Compared with the prior art, the textile cutting method and device of the present invention can ensure that the textile is cut into a uniform shape shards, and make sure they can be cut without sticking.

Background technique

In the field of textile testing, sheet-like textiles (such as fabrics, non-woven fabrics, fabric composite Pew, etc.) are often required to be shredded for the detection of various indicators, such as the detection of the pH value of textile water extract and its formaldehyde In the test of content, etc., it is necessary to cut the side textile into small squares of about 5 mm, and it is necessary to put the cut textile samples into containers to prepare multiple parallel samples. At present, the relevant work is mainly done manually. Due to the large number of textiles that need to be tested, a large number of personnel are required in the testing institution to manually cut the textiles into shredded samples with scissors, and then cut the shredded samples as needed. The sample is redistributed into the container.

At present, there are machines that can shred textiles, but they basically use a spiral knife to cut the fabric samples. The spiral knife has high requirements for installation and adjustment, and is easy to wear. After the tool is worn, the cutting will be incomplete. It is not easy for the shredded textile pieces to be automatically separated by weight, that is to say, the swatches chopped with a spiral knife are in a messy state, and it is difficult to automatically separate the shredded fabric samples according to the weight requirements of the inspection procedures. Put into a container such as a beaker or Erlenmeyer flask.

In view of the above problems, the present invention discloses a textile shredding method and a textile shredding device using the method. The textile shredding method uses a plurality of needles arranged in rows and columns to penetrate the textile and fix the textile in the On the needles, the textile is first cut into strips along the row or column arrangement direction of the needles by using a cutter, and then cut into pieces along the columns or rows of the needles, and the textile shredding device adopts The textile shredding method shreds textiles. Compared with the prior art, the textile shredding method and device of the present invention can ensure that the textiles are cut into pieces of uniform shape, and can be cut without sticking.

SUMMARY OF THE INVENTION

To the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a textile shredding method and a textile shredding device applying the method, the solutions of which are:

A textile shredding method, which is characterized in that needles parallel to each other and arranged in rows and columns are used to vertically pierce the textile with the needle tip along the length direction of the needle to keep the textile on the needle, and a cutter is used to cut the needle along the needle. The textile is cut into pieces in both the row and column directions of the needle arrangement, between the rows and rows of the needles and between the columns and the column, that is, the textile is cut into the row direction along the row direction of the needle arrangement. Strip, and then cut the strip textile into pieces along the column direction in which the needles are arranged.

A plurality of needles arranged in rows and columns are arranged in parallel at equal intervals in each row, and the distances between the rows and columns of the needles are respectively equal to the lengths of adjacent two sides of the textile pieces.

The number of the cutters is one or two, and each cutter includes one or more blades arranged in parallel. The larger number of the number of rows and columns of the object is less than 1. When there are two cutters, the arrangement direction of the blades on the two cutters is parallel to the row and column directions of the needle-like objects respectively.

The tips of the needles first pass through a blocking member with the same number and arrangement of holes as the needles, before piercing the textile, the needles can pass through the holes in the blocking member but are shredded The textile fragments cannot pass through. After the cutter cuts the textile into fragments, the needles are withdrawn from the textile fragments in the opposite direction as when piercing the textile, and the shredded textile fragments are blocked by the blocking member from the needles. quit.

The blocking member has protrusions protruding from the side surface on the side where the tip of the needle protrudes, the number and arrangement spacing of the protrusions are the same as the number and arrangement spacing of the needles, and each protrusion has a needle energy. Through holes, the needles first pass through the blocking member and its raised holes before piercing the textile, after the textile is shredded, the textile fragments are blocked by the protrusions when the needles move in the opposite direction as when piercing the textile Exit on the object.

When the textile is shredded, the needles move in the opposite direction to when the textile was pierced to remove the textile fragments from the needles, the needles can move one by one, row by row or multiple rows at the same time, corresponding to the textile fragments One-by-one, row-by-row, or simultaneous shedding from needles.

The textile pieces withdrawn from the needles fall onto the conveying device, and the conveying device conveys the textile pieces to move away from the conveying device sequentially along the length of the arrangement of the textile pieces.

The textile pieces withdrawn from the needles fall onto the conveying device. When the conveying device has only one conveying direction, the conveying device conveys the textile pieces and leaves the conveying device sequentially. When the conveying device has two conveying directions, the The textile pieces fall on the conveying device in the first conveying direction at the same time, and the conveying device in the first direction conveys the textile pieces on them to the conveying device in the second direction row by row or column by column, and the conveying device in the second direction conveys them in the upper row. The textile pieces are conveyed piece by piece from the conveyor.

In order to make the textile (especially the knitted fabric that is easy to curl) more stable when placed on the holding member, a negative pressure adsorption device can be used at the position where the holding member places the textile.

In order to prevent the textile fragments from falling on the blocking member or the convex lower end face of the blocking member normally, the needle moves in the opposite direction of the movement direction when it pierces the textile until the tip of the needle returns to the inside of the protrusion or blocking member Afterwards, the textile fragments are blown by the air blown out from the gap between the needle and the hole of the blocking member, so as to assist the textile fragments to retreat and clean the blocking member.

A textile shredding device is characterized in that it adopts the textile shredding method to cut textiles into pieces, which comprises a machine base, a needle board, a cutter, and a cutting moving device;

The needle plate is a plate-like or strip-like part on which at least one row of needle-like objects is installed at equal intervals. The other end of the needle-like objects that is different from the tip is fixed on the needle plate. The rows and columns are arranged in parallel and neatly, there is 1 row of needles on the strip needle plate, at least 2 rows of needles on the plate needle plate, at least one needle plate on the textile shredding device, there are multiple rows of needles, There are multiple columns, the spacing between the rows and columns of the needles is respectively equal to the length of two adjacent sides of the shredded textile pieces, and the needles are perpendicular to the needle plate.

The number of said cutters is one or two, and each cutter includes at least one blade. When a cutter contains multiple blades, the blades are equally spaced and aligned, and the blade spacing is the same as the needle row spacing or column spacing. Equally, the cutting edges of all blades are located on one face, and the number of blades is 1 less than the number of rows and columns of needles, whichever is greater. A relative cutting movement occurs in the row and column directions of the objects; when the blade is a circular blade, multiple circular cutters are worn on the cutter shaft, and the cutter shaft is installed on the machine base or the cutting moving device through the bearing seat. When there are two cutting knives, the blades on the two cutting knives are respectively parallel to the row and column directions of the needles.

The cutting moving device movably connects the machine base and the cutter or movably connects the machine base and the needle plate, drives and guides the cutter or the needle plate, so that the cutter and the needle plate can be opposed to each other along the row and column directions of the needle-shaped objects. The movement is to achieve two cutting movements respectively, the first cutting movement first cuts the textile into strips, and the second cutting movement cuts the strips of textiles into pieces.

When the textile shredding device has only one cutter, the textile shredding device further includes a rotating device, the rotating device movably connects the machine base and the needle board or movably connects the machine base and the cutter, and drives and guides the needle board or The cutter makes relative rotation between the needle plate and the cutter. The angle of relative rotation between the needle plate and the cutter is equal to the angle between the row direction and the column direction of the needles. No matter whether the needle plate rotates or the cutter rotates, as long as The projection of the needle-shaped object and the cutter on the plane where the cut textile is located produces a relative rotation, so that the two cuttings can be carried out in the row and column directions of the needle-shaped object respectively.

The textile shredding device further comprises a blocking part, a holding part, a holding moving device and a needling driving device,

The blocking member is a plate-shaped member with holes, and the number and distribution of the holes are the same as the number and distribution of the needles. The needle plate and the blocking member are aligned and movably connected, and there is a gap between the needle plate and the blocking member. The freedom of approaching and moving away, the needle passes through the hole of the blocking member, when the distance between the needle plate and the blocking member is relatively close, the tip of the needle penetrates the blocking member and protrudes a section, between the needle plate and the blocking member At greater distances, the tip of the needle does not penetrate the blocking member.

The holding member is a member for carrying the cut textile, the needle can pierce the textile placed thereon, the holding member is located on the side where the tip of the needle protrudes from the blocking member, and the holding moves The device is movably connected with the base and the holding part, and is used for guiding and driving the holding part to move to approach and away from the blocking part.

In order to make the textile more stable when placed on the holding member, a negative pressure adsorption device can be used at the position where the holding member places the textile.

The acupuncture driving device indirectly connects the machine base with the needle board or simultaneously connects the machine base with the needle board and the supporting part, drives and guides the needle board to drive the needle to move along the length direction of the needle or simultaneously drives and guides the needle board and The holding member moves along the length direction of the needle, so that there are three relative working positions between the tip of the needle and the holding member. When the needle is in its first working position, the needle does not pierce the blocking member, When the needle is in its second working position, the tip of the needle is between the holding member and the blocking member, and when the needle is in its third working position, the needle tip penetrates the holding member.

The blocking member has protrusions protruding from the side surface on the side where the tip of the needle protrudes, the number and arrangement spacing of the protrusions are the same as the number and arrangement spacing of the needles, and each protrusion has a needle energy. Through holes, the needles first pass through the blocking member and its raised holes before piercing the textile, and the needles can move freely along the length of the needles in the blocking member and its raised holes. The distance between the outer sides of each protrusion can be passed through the blade of the cutter, the needle tip is downwardly passed through the blocking member and the hole in the protrusion below it, and the protrusion blocks the movement of the textile toward the blocking member when the textile is cut. After the textile has been shredded, when the needle moves in the opposite direction as when piercing the textile, the textile fragments are blocked by the protrusions from exiting from the needle.

The textile shredding device also includes a conveying device installed on the machine base for receiving the shredded textiles detached from the needles and conveying them to leave in an orderly manner, and the conveying device at least includes a conveying device in one direction. When the conveying device includes two-direction conveying devices, the conveying directions of the two-direction conveying devices are horizontal and orthogonal, and the textile fragments detached from the needles fall on the first-direction conveying device and row by row or column by column. Being conveyed onto the conveying device in the second direction, the row of textile pieces on the conveying device in the second direction leaves the conveying device in the second direction piece by piece.

The needle plate side of the blocking member builds a quasi-closed positive pressure space, when the textile is chopped, the needle moves in the opposite direction of the movement when piercing the textile until the needle tip returns to the protrusion or blocking member After the inside, the positive pressure air in the positive pressure space is blown towards the textile pieces from between the needle and the hole of the blocking member, which can ensure that the textile pieces are normally withdrawn from the needle.

Due to the above mechanism, when the textile needs to be chopped, the needle plate carries the tip of the needle to pierce the textile, so that the textile is kept on the needle, and the cutter and the needle plate move relative to the row and column arrangement direction of the needle. The textile on the needle is shredded twice, the needle moves in the opposite direction when piercing the textile, and the shredded textile is blocked by the blocking member from being withdrawn from the needle.

Detailed ways

Several specific embodiments of a textile shredding method of the present invention and a textile shredding device applying the method are given below in conjunction with the legends. These embodiments are only examples of the present invention, and do not constitute a limitation to the claims of the present invention. What is not described in the present invention applies to the prior art.

Embodiment 1 of a textile shredding method of the present invention (as shown in Figures 3, 5, 6, and 7):

A textile shredding method, using a plurality of needles 61 parallel to each other and arranged in rows and columns along the length direction of the needles to pierce the textile with the tip of the needles 61 and then keep the textile on the needles 61,

The other end of the needle-shaped object 61 different from the tip is fixed on the needle plate 60, and the needle-shaped objects arranged in rows and columns have 20 (other numbers are not excluded) equally spaced (in this embodiment, the spacing is 6 mm, not Excluding other spacings), the row spacing of the needles is equal and equal to the length of one side of the textile fragment, the needle 61 has 20 (not excluding other numbers) columns, and the column spacing is equal to the other side of the textile fragment that needs to be chopped In this embodiment, the column spacing of the needles 61 is also 6 mm, but other column spacings are not excluded.

The cutter includes a plurality of circular cutters 34 arranged at equal intervals on the cutter shaft 37, and the number of the circular cutters 34 is larger than both the number of needles 61 in each row and the number of rows of needles 61. The number is less than 1. Since the needles 61 in this embodiment are 20 rows and 20 columns, the cutter has 19 circular cutters, and the distance between the circular cutters is equal to the row or column spacing of the needles 61, so that the cutters are cut once The textile to be cut can be cut into 20 pieces. Of course, the method of cutting one incision at a time with a single cutting blade is not excluded. When a single cutting blade is used to cut one incision at a time, the single cutting blade needs to be along the row direction of the needle and the direction of the needle. Cut multiple times in the column direction. In this case, the row spacing and column spacing of the needles can vary greatly. If a cutter with multiple blades is used to cut the textile into pieces in two times, the needles The difference between the row spacing and the column spacing of 61 should not be too large.

The axis line of the cutter shaft 37 is along the column direction of the needles 61. The rotation of the cutter around the axis of the cutter shaft drives the circular cutter 34 to rotate while moving in the row direction of the needles 61. The cutting edge moves and cuts between the rows of needles 61, so that the textile can be cut into strips parallel to the direction of the rows of needles, and the needle plate drives the textiles cut into strips to rotate 90 degrees or the cutter shaft 37 After rotating 90 degrees, the axis line of the cutter shaft 37 is along the row direction of the needles 61, and the edge cutting edge of the circular cutter 34 cuts the needles on the needles 61 between the rows of the needles 61 along the row direction of the needles 61. The strips of textiles are cut into textile pieces. No matter whether the needle plate rotates or the cutter rotates relative to the needle plate as a whole between two cuts, as long as the cutter can perform two cutting movements in the row and column directions of the needles 61, in comparison, The scheme of needle plate rotation is relatively simple. If the rows and columns of the needles 61 are not arranged in an orthogonal direction, the relative rotation angle between the textile and the cutting knife driven by the needles 61 between two cuts is not 90 degrees, but the rows and columns of the needles 61 are rotated. The angle between the arrangement directions. In addition, during the cutting movement, the needle-shaped object can also carry the textile to move in the horizontal plane, and the cutter rotates around its own axis at a fixed position, whether the needle-shaped object or the cutter translates in the horizontal plane to realize the cutting movement. The cutting motion can be realized as long as the projections of the needles and the cutter on the plane of the textile are moved relative to the row and column directions of the needles.

In order to facilitate the needles 61 to pierce the textile 9, the textile can be placed on a supporting board, which can be a hard board covered with a layer of soft, easily pierced objects (such as sponges, quilts, etc.) (like objects, fiber aggregates, etc.), the textiles 9 are placed on the surface of objects that are easily penetrated, and the textiles 9 placed on the hard board are manually aligned with the area where the needles 61 are located to make the textiles 9 and the needle-like objects. The objects 61 move toward each other until the needles 61 pierce the textile. Due to the friction between the textile 9 and the outer surface of the needle 61 after the textile 9 is pierced by the needle 61 , the friction can prevent the textile 9 from falling off the needle 61 .

After the textile is chopped, a fork with 21 long teeth is inserted horizontally between the textile pieces and the needle board along the column or row direction of the needle arrangement, and the textile pieces on the needle are pushed toward the needle tip with the fork. Push it away from the needle, the spacing between the tines is greater than the diameter of the needle, but not too much.

Embodiment 2 of a textile shredding method of the present invention (as shown in Figures 1-5 and 8-11):

The difference between this embodiment and the embodiment 1 of the method for shredding textiles is that:

As shown in Figures 10 and 11, in order to facilitate the removal of the shredded textiles from the needles 61, in this embodiment, an orifice plate 50 is added as a blocking member for withdrawing the textile fragments from the needles. The orifice plate 50 is a plate-like member having the same number and arrangement of holes as the needles 61 . In this embodiment, there are 20 rows and 20 columns of 400 orthogonally arranged holes on the orifice plate 50, which are arranged in a square matrix form. The outer diameter, the needles can pass through the holes on the orifice plate, but it is not excluded that the needles 61 and the holes on the orifice plate 50 are arranged in the shape of rectangle, diamond, etc. The round tube-shaped (not excluding hollow square tube and other shapes) protrusions 51 on the surface of the orifice plate 50, the number of protrusions 51 extending from one side of the orifice plate 50 and their arrangement spacing and the number of holes on the orifice plate 50 and their arrangement spacing The same, and each protrusion 51 has a through hole concentric with the hole on the corresponding orifice plate 50, the needle 61 can move freely along the length direction of the needle 61 in the hole of the orifice plate 50 and the protrusion 51 .

Each needle 61 first passes through a hole in the orifice plate 50 before piercing the textile 9. The tip of the needle 61 in FIG. 4 has been inserted into the hole of the orifice plate 50, as shown in FIG. 60 drives the needle-like object 61 to move downward through the holes in the orifice plate 50 and its protrusion 51 and then penetrate the textile 9, so that the textile 9 is fixed on the needle-like object 61, and the cutter shaft 37 rotates around its axis to drive While the circular cutter 34 rotates, it performs two cutting motions respectively along the row and column directions of the needles 61. The cutting edge of the circular cutter 34 is between the protrusions 51, so that the textile can be cut into side length and needle shape. When the cutting knife cuts the textiles, the textiles can contact the protrusions 51 to prevent the textiles from sliding along the length direction of the needles 61 to the needle board 60 when they are cut. At the same time, due to the protrusions The rib 51 has a certain height in the length direction of the needle. Even if the tensile deformation of the textile is large, as long as a certain staggered distance is maintained between the edge of the cutting edge and the end face of the protrusion contacting the textile, it can be cut to ensure that it will be cut open. After the textile is cut into pieces, the needle plate 60 drives the needle 61 to move upward in the opposite direction as when piercing the textile, and the tip of the needle 61 retracts into the hole of the protrusion 51 (as shown in FIG. 4 ), Fragments of the textile 9 are blocked by the lower end surfaces of the protrusions 51 from being withdrawn from the needle.

In order to facilitate the automatic tying of the textiles 9 to the needles 61 , the support plate 44 is arranged at a lower level than the lower end surface of the protrusion 51 of the orifice plate 50 , and the support plate 44 is provided with holes in the same way as the holes on the orifice plate 50 . a corresponding hole. When starting to cut the textile, put the textile 9 on the support plate 44, align the holes on the support plate 44 with the needles 61 on the needle plate, and the protrusions 51 of the hole plate 50 or the support plate 44 move towards each other to clamp To hold the textile, the needle plate 60 drives the needle 61 to move downward, the tip of the needle 61 pierces the textile 9 and then passes through the hole of the support plate 44, the textile 9 is held on the needle 61, the needle plate 60 and the The orifice plate 50 moves up and away from the support plate 44 together, so that the tip of the needle 61 is higher than the support plate 44, and the cutter performs a cutting motion. The relative movement between the supporting plate 44 and the orifice plate 50 is no matter which side moves, as long as the textile 9 can be clamped between the supporting plate 44 and the protrusion 51, and the supporting plate 44 can be separated to prevent it from hindering the cutting of the textile by the cutter. That's it. The support plate 44 can also be a flat box with holes on the top surface (the surface close to the protrusion 51). The box body is connected to the fan to make the inside of the box negative pressure. When the textile is placed on the top surface of the support plate, it can be relatively firm. It is a curled knitted fabric, which can effectively prevent curling. It is not excluded that the support plate 44 adopts the plan of the support plate in the first embodiment of the textile shredding method, and even the support plate is made of steel mesh or fabric stretched on the frame. Laid textiles and facilitate needle penetration of textiles.

In order to simplify the design of the scheme and reduce the difficulty and cost of processing, as shown in Figures 8 and 9, it is not excluded that the orifice plate 50 does not have protrusions 51, the orifice plate is only a plate-like part with holes, and the textile on the needle-like object 61 is not excluded. When the 9 is cut, the textile 9 keeps a certain distance from the lower surface of the orifice plate 50 and does not contact the orifice plate 50, and the cutting blade rotates at a high speed, so that even without the blocking of the protrusion 51, it can rely on the textile 9 and the needle 61. The frictional force of the textile keeps the position of the textile on the needle unchanged during the cutting process of the textile. After the textile is chopped, the needle moves upward, and the chopped textile is moved upward with the needle 61. The lower end face of the orifice plate 50 is blocked so that the shredded textile is withdrawn from the needles 61 . In this embodiment, the orifice plate 50 is used as the blocking member, and it is not excluded to use a sheet-like material that can be pierced by needle-shaped objects, such as fabric, wire mesh or film, which is straight and stretched in the photo frame-shaped member, as the blocking member. 61 first pierces the sheet material of the blocking member downward, and then continues to pierce the cut textile downward. After the textile is chopped, when the needle 61 is withdrawn, the sheet material of the blocking member can block the textile fragments from removing them from the needle. Up and down. It is also possible to use unidirectional parallel-arranged steel wires and other similar fence structure-shaped components as the blocking components, and the principle is the same.

Embodiment 3 of a textile shredding method of the present invention (as shown in Figures 1-5, 12, and 13):

The difference between this embodiment and the embodiment 2 of the method for shredding textiles is that:

20 needles 61 in each row are fixed on a strip-shaped needle strip 600. The cross-section of the needle strip 600 is rectangular (but other cross-sectional shapes such as circle or square are not excluded), and there are 20 needle plates in total When the needle strip 600 drives the needles 61 to move downward, all (20) needle strips can move downward together or one by one to penetrate the textile 9. After the textile 9 is cut into pieces, the needle strips can move upward one by one. Lift up, so that the textile fragments will be separated from the needles 61 row by row, and a conveyor belt 22 is arranged under the protrusion 51, and the transmission direction of the conveyor belt 22 is parallel to the length direction of the textile fragments falling on the needle strip 600. The textile scraps fall on the conveyor belt 22. When the conveyor belt rotates, the textile scraps can leave the conveyor belt piece by piece. At the end of the textile scraps leaving the conveyor belt 22, a collecting device for textile scraps (such as a bell mouth collecting device) is provided, and the textile scraps can enter the collection piece by piece. The device, the textile fragments exited by the collecting device fall into the container placed on the balance (conical flask, beaker, etc. or other revolving containers with smaller mass), which is beneficial to realize the automatic quantitative conveying of textile fragments after the textile is chopped Sampling, because the quality of a single chopped textile fragment is small, the accuracy of quantitative control can easily be controlled within the range of positive and negative textile fragments, which can meet the precision requirements for fixed-weight sample preparation in textile testing. If the textile is relatively light and thin, two, three or more needle strips 600 can be lifted at a time, so that two, three or more rows of textile fragments will fall on the conveyor belt, and there will be two, three or more rows of textile fragments when the conveyor belt 22 rotates. Three or more pieces of textile fragments are gradually collected into the collection device, thereby improving the speed of automatic custom-weight sample making.

The cutter adopts a row of wallpaper knife blades arranged at equal intervals. The blade spacing is equal to the spacing between the rows and columns of the needles. The cutter moves horizontally along the 61 rows and columns of the needles. The wallpaper knife is between the needles to cut textiles. In addition to wallpaper knife blades, it is not excluded to use other shapes of plane blades, such as razor blades.

Embodiment 4 of a textile shredding method of the present invention:

The difference between this embodiment and the embodiment 2 of the method for shredding textiles is that:

In this embodiment, two sets of cutting knives are used. The cutting blades of the two sets of cutting knives are respectively parallel to the row and column directions of the needles. The two sets of cutting knives cut the textiles along the row and column directions of the needles. The needle and cutter do not need to be rotated to adjust the cutting direction between cutting movements.

Two conveyor belts with horizontal and orthogonal conveying directions are arranged below the protrusions 51. The conveying direction of the second conveyor belt is parallel to the row direction or column direction of the textile pieces falling on the needle board. All the textile pieces falling on the needle board are arranged in parallel. Falling on the first conveyor belt, the first conveyor belt conveys the textile scraps on it row by row or column to the second conveyor belt, and the second conveyor belt transports a row of textile scraps placed along its length on it piece by piece The conveying leaves the conveyor belt, and the requirement of constant weight control can also be realized.

Embodiment 5 of a textile shredding method of the present invention:

The conveyor belt not only serves as a component for transporting textile fragments, but also replaces the pallet as a component for placing the textiles to be cut. The conveyor belt has the freedom to approach and move away from the tip of the needle. It is relatively stable when placed on the part, and the part where the textile is placed on the supporting part adopts a negative pressure adsorption device. After the textile to be cut is placed on the conveyor belt, the textile is adsorbed on the surface of the conveyor belt by negative pressure, and the conveyor belt moves to the blocking part to make the textile contact the blocking part. or bulge, the needles pierce the textile and the conveyor belt and keep the textile on the needles, the conveyor belt is away from the blocking part or the bulge, the cutter cuts the textile into pieces, the conveyor belt moves again until the textile pieces are in contact with the conveyor belt and the fan is started Negative pressure adsorption is generated on the surface of the conveyor belt, and at the same time, the needle moves in the opposite direction of the movement direction when piercing the textile until the needle tip returns to the inside of the protrusion or blocking member, and the textile fragments are adsorbed on the conveyor belt.

Further, in order to prevent the textile fragments from falling on the blocking member or the convex lower end surface of the blocking member, a quasi-closed positive pressure space is constructed on the side of the needle plate of the blocking member. When piercing the textile, the movement direction moves in the opposite direction until the needle tip returns to the inside of the protrusion or the blocking member, and the positive pressure air in the positive pressure space is blown to the textile fragments from between the needle and the hole of the blocking member, It ensures that the textile pieces are properly withdrawn from the needle.

Embodiment 1 of the textile cutting device of the present invention (as shown in Figures 6 and 7):

A textile shredding device is characterized in that it adopts the textile shredding method to cut textiles into pieces, and includes a machine base 10, a needle plate 60, a rotating device, a cutter, and a cutting moving device.

The machine base 10 is a plate-shaped or frame-shaped part, and a foot 11 is installed at the lower part thereof, and the machine base 10 can be placed on a test bench or on the ground by means of the foot 11 .

The needle plate 60 is a plate-like part on which a plurality of needles 61 are installed at equal intervals. The other end of the needles 61 different from the tip is fixed on the needle plate 60. The needles on the needle plate 61 are arranged in rows and columns, and the needles arranged in the rows and columns have 20 (other numbers are not excluded) equally spaced in each row (the spacing in this embodiment is 6mm, other spacings are not excluded) arranged in parallel, the needles 61 The rows of the arrangement are equally spaced and equal to one side of the textile piece, the needles have 20 (other numbers not excluded) columns and the column spacing is equal to the length of the other side of the textile piece that needs to be chopped, for example, textile 9 needs to be cut into 6mm sides For a long square, the row and column spacings of the needles 61 are both 6mm. A needle board with 20 rows and 20 columns of needles with a spacing of 6mm can fix up to a square with a side length of 120mm.

The rotating device is a device that drives and guides the needle 61 or the cutter to rotate. In this example, the needle 61 is rotated, and the rotating plate 570 is downward and the corner cylinder 57 indirectly hung on the upper part of the machine base 10 is used as the rotation. Device, the top surface of the needle plate 60 is connected to the rotating plate 570 of the corner cylinder 57 through the needle plate connector 550, the tip of the needle 60 is downward, the corner cylinder 57 drives the needle plate 60 to rotate, and the needle plate 60 rotates with an orthogonal There are two working positions, and the included angle between the two working positions is 90 degrees. It is not ruled out that other methods such as motor, cylinder plus connecting rod, cylinder plus rack and pinion are used as rotating devices to drive the needle plate to rotate, and a guide mechanism is added accordingly. At the same time, it is not ruled out that the way of manually rotating the needle plate 60 is used to replace the rotation driving function of the rotating device. In this case, the rotating device only retains the guide bearing.

The cutter includes a plurality of circular cutters 34 with holes in the middle, which are coaxially sleeved on the cutter shaft 37 and arranged at equal intervals. The cutting edges of the circular cutters 34 are located on the outer circumferential surface of an imaginary cylinder. The number is one less than the number of needles 61 in each row and the number of rows of needles 61 , whichever is greater. Since the needles 61 in this embodiment are 20 rows and 20 columns, there are 19 circles on the cutter. The distance between the cutter and the circular cutter is equal to the row or column spacing of the needles 61, so that the cutter can cut the textile to be cut into 20 pieces at a time. When a single cutting blade is used to cut one incision at a time, the difference between the row spacing and column spacing of the needles can be relatively large. big. It is not ruled out that the cutter adopts a row of equally spaced, non-rotating wallpaper knife blades, the blade spacing is equal to the spacing between the rows and columns of the needles, and the cutting edge of the blade is located on a plane with a certain angle to the plane where the needle tip is located. In the above, the cutter moves horizontally along the row and column directions of the needles 61. During the horizontal movement of the cutter, the cutting edge of the wallpaper knife is located between the needles to cut textiles. Except for the wallpaper knife blade, it is not excluded to use other shapes of planes. Blades, such as razor blades, etc., also do not exclude the use of a single non-rotating blade for cutting textiles.

The cutter shaft 37 is connected with the shaft of the motor 35 through the coupling 36. The motor 35 and the cutter are respectively installed on the cutting slide block 32 through the motor mounting bracket 350 and the cutter bearing seat 33, and the cutting slide block 32 is slidably assembled on the cutting guide rail. 31, the cutting guide 31 is horizontally installed on the machine base 10, the cutting slider 32 and the cutting guide 31 are used as the cutting guide parts of the cutting mobile device, the length direction of the cutting guide 31 is parallel to the plane where the circular cutter 34 is located, and the motor 35 passes through the coupling shaft. The cutter 36 drives the circular cutter 34 on the cutter shaft 37 to rotate, and at the same time, the driving part of the cutting moving device is used to drive the cutting knife to move along the length of the cutting guide rail 31. The driving part of the cutting moving device is not shown in the figure. The range of movement of the cutting guide 31 ensures that the cutter can cut the entire range of textiles, that is, the cutter can move to the left until the axis of the cutter shaft 37 is located to the left of the projection of the plumb bob of the leftmost needle (the position shown in FIG. 6 ). ), and can move to the right until the axis of the cutter shaft 37 is located on the right side of the projection of the plumb bob of the rightmost needle. The cylinder connected to the cutting slider 32 can also use a motor plus a lead screw, a motor plus a pulley plus a belt, a cylinder plus a connecting rod system, etc.

Due to the above mechanism, when the textile needs to be chopped, the needle 61 on the needle plate 60 is used to pierce the textile, so that the textile 9 is kept on the needle 61. The cutter rotating around the axis of the cutter shaft is shown in Figure 6. The whole piece of textile on the needle 61 is cut into 20 pieces by moving from left to right in the middle. The corner cylinder 57 drives the needle plate 60 to rotate 90 degrees, and the rotating cutter moves from right to left (or left to right). Cut the 20 textile strips into 400 textile pieces with a side length of 6 mm. During the movement, the cutter is driven by the motor 35 to rotate around the axis of the cutter shaft, which is conducive to smooth cutting. If the cutter blade is sharp enough, the motor 35 and the coupling 36 can be removed. Contact and cutting with the textile causes the cutter to rotate about the cutter axis.

In order to facilitate the needles 61 to pierce the textile 9, the textile can be placed on a supporting board (the supporting board can be a hard board covered with a layer of soft, easily penetrated, such as sponge, quilt-like Objects, fiber aggregates, etc., the textile 9 is placed on the surface of the object that is easily penetrated) or on a frame-shaped holding frame (the holding frame is stretched with fabrics, steel meshes, etc., which are easily penetrated by needle-like objects. The frame-like part of the object, the textile is placed on the fabric or wire mesh that is easily penetrated), the textile 9 can be aligned with the area where the needle 61 is located by manually holding the holding plate or the holding frame, and then the textile 9 will be moved to the area where the needle 61 is located. The needle plate 60 is moved in a direction to cause the needles to pierce the textile. Because of the friction between the textile 9 and the outer surface of the needle 61 after the textile 9 is pierced by the needle 61 , the friction can stably prevent the textile 9 from falling off the needle 61 .

Although the needle plate is used in this embodiment to drive the textile 9 to rotate 90 degrees, it is not excluded that the needle plate does not rotate but changes the moving direction of the cutter, and the cutter shaft 37 is rotated 90 degrees in the horizontal plane between two times of cutting the textile. degree, so that the circular cutter 34 reciprocates and cuts along the row and column directions of the needles 61, respectively. It has 90 degrees of rotational freedom in the horizontal plane, and has movement degrees of freedom in the two orthogonal directions of the rows and columns of the needles 61; The above additional angle motor drives the movement of the cutter in two horizontal and orthogonal directions; these specific implementations are common knowledge in the field, and will not be repeated here, and these solutions are not simpler than the aforementioned solutions. In short, as long as the cutter and the needle plate can be realized The relative cutting motion between the two directions of the rows and columns in which the needles 61 are arranged is sufficient. In this embodiment, the needle plate is placed horizontally, and the tips of all needles are located on a horizontal plane, and the movement of the cutter is also horizontal. The cutter moves up and down horizontally, in short, as long as the relative cutting motion between the needle and the cutter is realized.

Embodiment 2 of the textile shredding device of the present invention (as shown in Figures 8 and 9):

This embodiment adds a blocking member, a holding member, a holding moving device (guide and drive the holding member to move) and a needling driving device on the basis of the first embodiment of the textile shredding device,

The blocking member is used to withdraw the textile fragments from the needle. In this embodiment, the blocking member adopts the orifice plate 50, and the holding member adopts the supporting plate 44. The orifice plate 50 and the supporting plate 44 are both. A plate-shaped component with holes, and the number and distribution of the holes are the same as the number and distribution of the needles 61. In this embodiment, there are 20 rows and 20 columns on the orifice plate 50 and the support plate 44, a total of 400 The orthogonally arranged holes are arranged in a square matrix form, which is the same as the number, arrangement method and arrangement spacing of the needles 61 on the needle plate, but it is not excluded that the holes on the needles 61, the orifice plate 50 and the support plate 44 are all the same. Arranged in shapes such as rectangles, diamonds and other numbers, the diameters of the holes on the orifice plate 50 and the support plate 44 are both larger than the outer diameter of the needles 61 .

The plate-shaped orifice hanging plate 56 is horizontally mounted on the lower end surface of the turning plate 570 of the corner cylinder 57 (rotating device), and the plate-shaped acupuncture cylinder mounting plate 53 is horizontally suspended by four column-shaped needle-punching cylinder mounting plate connectors 55. It is hung and installed under the hanging plate 56 of the orifice plate, and the acupuncture double-rod cylinder 540 installed on the acupuncture cylinder mounting plate 53 is used as the acupuncture driving device, and the double-rod cylinder is used as the needle. The needle plate 60 of the puncturing driving device will not rotate in the horizontal plane. The acupuncture double-rod cylinder 540 can not only drive the needle-like objects 61 to move, but also guide the needle-like movements. Therefore, it is not excluded to use a single-rod cylinder or a motor plus a screw rod as the acupuncture drive device. Even so, the needle plate will not rotate in the horizontal plane. The needles 61 installed on the plate 60 have their tips pointing downward, and the orifice plate 50 is horizontally hoisted under the acupuncture cylinder mounting plate 53 through four columnar orifice plate connectors 52, and the tips of each needle 61 pass downward through the holes. in a hole in the plate 50. The support plate 44 is horizontally installed on the support plate slider 42 under the hole plate 50 through the support plate bracket 43, the support plate slider 42 is movably assembled on the cutting guide rail 31, and the support plate slider 42 and the cutting guide rail 31 are supporting moving devices The holes on the support plate 44 are aligned with the holes on the orifice plate 50 in the plumb direction. The acupuncture double-rod cylinder 540 has two-stage strokes or two single-stage double-rod cylinders connected in series, and the cylinder rod at the end of the acupuncture double-rod cylinder 540 has three positions, corresponding to the needle-shaped object 61 having the third position in the height direction. The first, second and third positions are in total. The first working position of the needle 61 is the position where the needle 61 is higher than the position shown in FIG. 8 . When the needle 61 is in its first working position , the lower tip of the needle 61 is retracted upward into the hole of the orifice plate 50, that is, the tip of the needle 61 is higher than the lower surface of the orifice plate 50; the second working position of the needle 61 is the position shown in FIG. 8 , when the needle 61 is in its second working position, the tip of the needle 61 is higher than the upper surface of the support plate 44 and lower than the lower surface of the orifice plate 50; the third working position of the needle 61 is the needle The tip of the object 61 moves downward to a position lower than the lower surface of the pallet 44 .

The supporting mobile device guides and drives the supporting plate 44 to move. The driving components of the cutting mobile device and the driving components of the supporting mobile device are not shown in FIGS. 8 and 9. The cutting mobile device guides and drives the cutter to move along the cutting guide rail 31 to realize The method and method have been described in the previous embodiments, the driving component of the supporting mobile device drives the supporting plate 44 to move horizontally along the cutting guide rail 31, the structure and working principle of the supporting mobile device are the same as the cutting mobile device, and the moving range makes the supporting plate 44 move horizontally. The plate 44 has two working positions, namely the first working position of the pallet and the second working position of the pallet. When the pallet 44 is in the first working position of the pallet, the hole on the pallet 44 and the hole on the orifice plate 50 The direction of the plumb bob is aligned and the needle driving device can drive the needle to pierce the hole on the support plate 44. When the support plate 44 is in the second working position of the support plate, the needle cannot pierce the hole on the support plate 44. In the embodiment, when the supporting plate 44 is in the second working position of the supporting plate, the supporting plate 44 and the orifice plate 50 are completely separated from the projection in the plumb direction, corresponding to the movement of the supporting plate 44 to the right in FIG. Right side of the plumb projection of the needle on the right.

Thanks to the above mechanism, the working principle of the textile shredding device in this embodiment is: when the textile needs to be cut, the cylinder rod of the double-rod acupuncture cylinder 540 drives the needle 61 to move to its first or second working position, The pallet 44 is moved to its second working position, the textile 9 is placed on the pallet 44, the moving device drives the pallet to move to its first working position, and the needle-punching double-rod cylinder 540 drives the needle 61 to move to In its third working position, the tip of the needle-like object 61 pierces the textile on the pallet 44 and continues to move downward for a distance to pierce the lower surface of the pallet 44, the textile 9 is held on the needle-like object 61, and the needle The retraction of the cylinder rod of the thorn double-rod cylinder 540 drives the needle 61 to return to its second working position as shown in FIG. Drive the cutter to rotate, and the cutting moving device drives the cutter to move from the position shown in FIG. 8 to the right to cut the textile on the needle 61 into strips, and then continue to move to the right for a certain distance until the needle plate 60 rotates. At the position where 61 does not interfere with the cutter, the rotation of the rotating plate 570 of the corner cylinder 57 drives the needle plate 60 to rotate 90 degrees, the motor 35 drives the cutter to rotate, and the cutting moving device drives the cutter to move leftward to the position shown in Figure 8. At the position, the textile 9 is cut into small pieces, the holding and moving device drives the pallet 44 to move to its first working position, the cylinder rod of the double-rod acupuncture cylinder 540 continues to retract, and the needle continues to return upward to its first working position. In a working position, when the needle-like object 61 is rising, the textile fragments carried on the needle-like object 61 contact the lower surface of the orifice plate 50 and are prevented from falling off onto the support plate 44 .

Further, in order to prevent the textile fragments from being caught by the blocking member or the lower end surface of the protrusion and cannot be dropped normally, the space between the orifice plate 50 as the blocking member and the acupuncture cylinder mounting plate 53 is closed, and the fan is connected to the Blow air in the closed space, so that the closed space is a positive pressure space, when the textile is chopped, the needle moves in the opposite direction of the movement direction when piercing the textile until the needle tip returns to the inside of the protrusion or blocking member Afterwards, the positive pressure air in the positive pressure space is blown towards the textile fragments from between the needle-shaped object and the hole of the blocking member, which can ensure that the textile fragments are normally withdrawn from the needle-shaped object.

In addition, it is not ruled out that the movement of the needle in its length direction only retains two working positions, and the support plate 44 as a holding member is added a degree of freedom of movement in the movement direction of the needle, which is used to stab the textile. Pierce and hold on the needle, in short, the needle and the holding part have 3 relative positions in the length of the needle to automatically pierce the textile, hold the textile cut, and cut the shredded textile pieces The function of withdrawing from the needle.

Although the orifice plate 50 is used as the blocking member in this embodiment, it is not excluded to use a sheet-like material that can be pierced by needles, such as fabric, wire mesh or film, which is stretched straight in the photo frame-shaped member, as the blocking member. The piece 61 first pierces the sheet material of the blocking member downward, and then continues to pierce the cut textile downward. After the textile is chopped, when the needle 61 is withdrawn, the sheet material of the blocking member can block the textile fragments from removing them from the needle. back up and down. Alternatively, unidirectional parallel-arranged steel wires, fibers, ropes and other similar fence structural parts can be used as the blocking parts. Before the needles pierce the textile, they first pass through the gaps of the fence structural blocking parts, and the textile fragments are retracted after the needles. During the process, it is blocked from the needle-like object by the blocking member in the shape of a fence structure.

Embodiment 3 of the textile shredding device of the present invention (as shown in Figures 10 and 11 ):

The difference between this embodiment and the second embodiment of the textile shredding device is:

The acupuncture double-rod cylinder 540 as the acupuncture driving device only has a single stroke, and the other stroke is replaced by the stroke of the pressing cylinder 572 installed on the machine base 10 with an indirect plumb. The corner cylinder mounting bracket 58 is installed on the pressing slide. On the block 571, the pressing slider 571 is slidably assembled on the pressing guide rail 573, the pressing guide rail 573 is indirectly installed on the machine base 10 in the direction of the plumb weight, and the pressing cylinder 572 drives the entire corner cylinder 57 to move up and down, that is, the acupuncture drive device A compression cylinder 572 and a double-rod cylinder 540 for acupuncture are included.

In Example 2 of the textile shredding device, the textiles tend to move upwards when they are cut on the needles 61, which may cause the incision to be completed. The number of protrusions 51 protruding from one side of the orifice plate 50 and their arrangement spacing are the same as the number of holes on the orifice plate 50 and their arrangement spacing, and each protrusion 51 There are holes concentric with the holes on the corresponding orifice plate 50 with the same diameter, and the needle-like objects 61 can move freely along the length direction of the needle-like objects 61 on the orifice plate 50 and in the holes of the protrusion 51. The spacing between the outer sides of the protrusions 51 can be passed through the blade of the cutter, and the tips of the needles 61 pass downwardly through the holes in the orifice plate 50 and the protrusions 51 below.

Due to the above mechanism, the working principle of the textile shredding device in this embodiment is: when the textile needs to be cut, the cylinder rod of the pressing cylinder 572 is extended to drive the corner cylinder 57 to rise, driving the needle 61 and the orifice plate 50 together. When the lower surface of the protrusion 51 is higher than the height of the support plate 44, the cylinder rod of the acupuncture double-rod cylinder 540 is retracted to drive the tip of the needle 61 to retract into the hole of the protrusion 51 (the The tip is higher than the lower surface of the protrusion 51), the pallet 44 is moved to its second working position, the textile 9 is placed on the pallet 44, the support moving device drives the pallet 44 to move to its first working position, and the press The cylinder rod of the tightening cylinder 572 is retracted to drive the corner cylinder 57 to descend, driving the needle 61 and the orifice 50 to descend together to the lower surface of the protrusion 51 to press the textile on the support plate 44 to prevent the needle 61 from piercing the textile. When the textile is wrinkled, the cylinder rod of the needle-punching double-rod cylinder 540 is extended to drive the tip of the needle 61 to pierce the textile on the pallet 44 and continue to move downward for a certain distance, and the textile 9 is held on the needle 61 , and the upper surface of the textile is in contact with the lower surface of the protrusion 51, and the cylinder rod of the pressing cylinder 572 is extended to drive the corner cylinder 57 to rise and drive the needle 61 to rise until the tip of the needle 61 is higher than the upper surface of the support plate 44. , the supporting moving device drives the pallet 44 to move to its second working position, the motor 35 drives the cutter to rotate, and the cutting moving device drives the cutter to move to the right from the position shown in FIG. After cutting into strips, continue to move a certain distance to the right to the position where the needle 61 does not interfere with the cutter when the needle plate 60 rotates. During the process of cutting the textile, the cutting edge of the circular cutter 34 is on the protrusion 51. In between, because the lower surface of the protrusion 51 blocks the textile so that it cannot move upward, it is ensured that it can be cut. The rotation of the rotating plate 570 of the corner cylinder 57 drives the needle plate 60 to rotate 90 degrees, the motor 35 drives the cutter to rotate, and the cutting moves The device drives the cutter to move to the left to its position as shown in FIG. 10 , cuts the textile 9 into small pieces, the supporting and moving device drives the pallet 44 to move to its first working position, and the needle punches the double-rod cylinder 540 . The retraction of the cylinder rod drives the needle 61 to retract upward into the hole of the protrusion 51, and the shredded textile pieces on the needle 61 are prevented from coming off the needle 61 to the lower surface of the protrusion 51 in contact with the lower surface of the protrusion 51. On the pallet 44, of course, it is not excluded that the shredded textile pieces fall into the manually-held container for receiving the textile pieces. When the textile pieces fall into the manually-held container, the pallet 44 can still be in its second position. work location.

Embodiment 4 of the textile shredding device of the present invention (as shown in Figures 12 and 13 ):

The textiles in Example 3 of the textile shredding device are cut into pieces and all fall down together, which is not conducive to automatically weighing the shredded textile pieces into a sample of fixed weight. The needle plate 60 is changed to a plurality of needle strips 600, and a conveyor belt 22 is added as a conveying device. Only one row (or one column) of needles 61 is installed on each needle strip 600. For example, in the foregoing embodiment, there are 20 rows, 20 The needle plate 60 of the column needles 61 is replaced with 20 long needle strips 600, 20 needles are installed on each needle strip 600, and the 20 needle strips are arranged in parallel with each other, so that the The spacing between rows and columns is the same as the spacing between the needles 61 in Example 3 of the textile shredding device, and the double-rod cylinder 540 used for driving the needle punching action is changed to 20 needle punching cylinders 54. A needle strip 600 is connected to the end of the cylinder rod with the plumb down of each acupuncture cylinder 54. Since the needle 61 is located in the hole of the orifice plate, even if a single-rod cylinder is used, the needle strip 600 will not be in the horizontal plane. turn inside. The conveyor belt 22 is installed on the machine base 10 through the conveyor belt bracket 20 and the conveyor belt roller 21. The transmission direction of the conveyor belt is the same as the moving direction of the pallet 44. Of course, it is not ruled out that the conveying direction of the conveyor belt is other directions, and even the moving direction of the pallet 44 can also be For other directions such as the direction orthogonal to the direction in Embodiment 3 of the textile shredding device in the horizontal plane, the conveyor belt is located at the lower part of the motor mounting bracket 350 to ensure that the cutter does not interfere with the conveyor belt 22 when the cutter moves.

The working principle of this embodiment:

When it is necessary to pierce the textile, the cylinder rods of all the needle punching cylinders 54 are extended simultaneously to drive the needles 61 on all the needle strips 600 to pierce the textile together. When the textile 9 is shredded, the textile fragments need to be removed from the needle When the needle 61 goes up and down, the needle punching cylinder 54 drives the needle strips 600 to lift up one by one or in a combination of different numbers. On the conveyor belt 22, the rotation of the conveyor belt 22 transports one or more rows of textile scraps falling on the conveyor belt 22 away from the conveyor belt 22 piece by piece, so that the textile scraps leave the conveyor belt 22 one by one in an orderly manner, or more (depending on the needle boards that are lifted at the same time) Strips 600 pieces) leave the conveyor belt 22 in an orderly manner, if a collecting device, a container and a balance are placed under the end of the conveyor belt 22, and the container is placed on the balance, the textile pieces leaving the conveyor belt 22 are ordered through the collecting device piece by piece (or Each time a few pieces) fall into the container, the mass of the textile fragments in the container increases monotonically, and the growth rate depends on the number of needle strips 600 lifted each time and the conveying speed of the conveyor belt 22, and the balance weighs out the textile fragments in the container. After mass, the weighing data is uploaded to the computer through communication, and the computer can control the lifting quantity of the needle strip 600 and the rotation of the conveyor belt 22 accordingly, which is convenient to automatically use the chopped textiles to prepare test samples that meet the weight requirements. It is not limited that the conveying device must be a conveyor belt, such as vibration transmission and other devices that can realize the orderly transmission of textile fragments can be used as the conveying device.

It is also possible to use a conveyor belt 22 to replace the function of the holding member. The conveyor belt uses a material that can be pierced by needles (such as a mesh conveyor belt or a perforated conveyor belt), and the textile is placed on the conveyor belt to add an approach to and away from the needle. The freedom of movement of the object (in the direction of the plumb bob in the figure), that is, the holding moving device guides and drives the conveyor belt to approach and move away from the needle in the direction of the plumb bob, and because of this degree of freedom, the pressing cylinder 572 can be removed. , when the textile needs to be cut, put the textile on the conveyor belt, the holding moving device drives the conveyor belt to rise to the upper surface of the conveyor belt and contacts the lower end surface of the protrusion 51, the needle driving device drives the needles to pierce the conveyor belt, and the holding The moving device drives the conveyor belt down so that the surface of the conveyor belt is at a distance from the tip of the needle, and the cutter cuts the textile into pieces and then falls off the textile pieces and transports them away on the conveyor belt. In order to make the textiles (especially the knitted fabrics that are easy to curl) more stable when placed on the holding member (the conveyor belt in this embodiment), in this embodiment, the conveyor belt adopts a negative pressure adsorption device, and the textile to be cut is placed on the conveyor belt. After loading, the textile is adsorbed on the surface of the conveyor belt by negative pressure. This kind of conveyor belt with negative pressure adsorption function is common knowledge in the industry. Basically, a space for connecting the fan is built under the conveyor belt. The specific implementation method will not be repeated. When the textile fragments fall on the conveyor belt, because the conveyor belt has the function of negative pressure adsorption, the textile fragments can be better controlled, so that the arrangement of the textile fragments can be kept orderly and conveyed. In this case, on the one hand, the textile to be cut is flat on the conveyor belt, and it is easier to penetrate evenly; on the other hand, after the textile is cut, the conveyor belt is raised again to contact the textile fragments, and the textile fragments are pulled back when the needles are withdrawn. Adsorbed on the conveyor belt, the textile pieces are not messed up and are more easily transported off the conveyor belt row by row or column by column.

And even the needle strip 600 can be further replaced with single needle drive, for example, using 400 individually driven needles, so that the conveying device can be omitted, and by controlling the number of single needles each time it is lifted, it is possible to control the number of textiles falling down to a fixed weight. , the falling textile fragments can fall directly into the collecting device located under the needle plate.

It is not excluded to add a second conveyor belt below the end of the conveyor belt 22 in the conveying direction, the conveying directions of the two conveyor belts are horizontally orthogonal, and the conveying direction of the second conveyor belt is parallel to the row direction or column direction of the arrangement of textile fragments falling on the needle board. , the needle slats are lifted together after the textile is chopped like a needle board, and all the textile fragments on the needle fall together on the first conveyor belt, and the first conveyor belt conveys the textile fragments on it row by row or column by column to the On the second conveyor belt, the second conveyor belt transports a row of textile scraps placed on it along its length away from the second conveyor belt piece by piece, so that the transfer of textile scraps can be controlled using both needle boards and fixed weights.

The movement driving mode of the needle plate and the needle strip 600 can also adopt a moving roller plus a lever or a jacking mechanism, or a pulling rope spring tightening mechanism, etc. No matter which method is adopted, it is necessary to ensure that the needle can pierce the textile and remove the textile. Fragments recede from the needle.

Example 5 of the textile cutting device of the present invention:

The difference between this embodiment and the first embodiment of the chopping device is that the rotating device in the first embodiment of the chopping device is eliminated, that is, the corner cylinder 57 in the first embodiment is removed, and the needle is no longer rotated. It can cut textiles in the row and column directions of the needles, respectively, and two sets of cutters with the axis line of the cutter shaft parallel to the row and column directions of the needles are arranged outside the distribution range of the needles. The textiles are cut along the row and column directions of the needles respectively, and the angle between the cutter axes of the two sets of cutters is equal to the angle between the rows and columns of the needles.
