Technical Field

The invention belongs to the technical field of textile equipment, and in particular relates to a shoe upper machine which is easy to repair and adjust.

Background Art

In the field of knitting technology, hosiery machines are one of the most common knitting equipment. The most important functional part is the loop forming system, which includes a needle cylinder with a needle groove in which knitting needles are placed. The knitting needles are driven by a triangle to move along the needle groove to realize needle collection and needle release to complete the loop forming process.

With the continuous updating of textile technology, the structure of hosiery machines has become more and more complex, and the functions have become more and more. At the same time, there are also some problems. For example, the Chinese invention patent with publication number CN207659604U and the Chinese invention patent with publication number CN111118722B both have the problem that during the operation of the machine, the internal situation cannot be checked and the program cannot be adjusted in time.

By adopting the above technical scheme, the current upper machines are relatively mature, including a syringe, a hood, a half disk, a yarn feeding assembly, a first power assembly, a second power assembly and a third power assembly, etc. In order to realize the ability to observe the internal situation of the machine at any time, it is necessary to be able to open the machine head at any time, that is, to separate the half disk from the syringe. To solve this technical problem, the present invention is provided with a support seat and a mounting ring, and the half disk and the mounting ring are hinged on the support seat, and the yarn feeding assembly is installed on the mounting ring, so that the machine can be separated from the syringe by flipping the mounting ring or the half disk without stopping, thereby facilitating the staff to observe the internal situation of the machine.

The present invention is further configured as follows: two first mounting ear plates are arranged on the outer wall of the mounting ring, and the two first mounting ear plates are hinged to the support seat.

By adopting the above technical solution, the mounting ring is hinged to the support seat through two second mounting ear plates, so as to facilitate installation and disassembly.

The present invention is further configured as follows: a first limiting portion is provided on the outer wall of the mounting ring and is arranged opposite to the first mounting ear plate; when the mounting ring is covered on the sinker cover, a first supporting portion for supporting the first limiting portion is provided at a position on the frame directly opposite to the first limiting portion so that the mounting ring is on a horizontal plane.

By adopting the above technical solution and providing the first limiting portion and the first supporting portion, the mounting ring can be stably covered on the sinker cover.

The present invention is further configured as follows: the third power assembly includes an articulated seat, a connecting seat, a power motor, a rotating shaft, a first transmission shaft, a second transmission shaft, a third transmission shaft, a first umbrella gear, a second umbrella gear, a third umbrella gear, a fourth umbrella gear, a fifth umbrella gear and a sixth umbrella gear;

The hinge seat is provided with two second mounting ear plates, and the hinge seat is hinged to the support seat through the two second mounting ear plates. The hinge shaft on the first mounting ear plate is the same as the hinge shaft on the second mounting ear plate. The connecting seat is fixed to the upper end of the side of the hinge seat. The lower end of the rotating shaft is connected to the power motor through a gearbox, and its upper end is rotatably connected to the support seat and extends upward. The first bevel gear is arranged on the protruding end of the upper end of the rotating shaft; the lower end of the first transmission shaft passes through the hinge seat and leads to the first bevel gear. The second bevel gear is arranged at the lower end of the first transmission shaft and is connected to the first bevel gear. The gears are engaged, the upper end of the first transmission shaft is rotatably connected to the connecting seat, and the third bevel gear is arranged on the upper side of the first transmission shaft; the second transmission shaft is located in the connecting seat, and both ends extend out of the connecting seat respectively, the fourth bevel gear is arranged at one end of the second transmission shaft and is meshed with the third bevel gear, and the fifth bevel gear is arranged on the other end of the second transmission shaft; a mounting plate is also arranged on the side of the connecting seat away from the first transmission shaft, the third transmission shaft is rotatably connected to the mounting plate, the sixth bevel gear is arranged on the third transmission shaft, and the lower end of the third transmission shaft extends downward to the half plate;

By rotating the hinge seat, the Huff plate rotates toward or away from the sinker cover, and the meshing teeth between the first bevel gear and the second bevel gear increase or decrease.

By adopting the above technical scheme, in order to achieve flipping, the present invention improves the transmission mode of the third power component for driving the Huff disk to rotate, which mainly includes an articulated seat, a connecting seat, a power motor, a rotating shaft, a first transmission shaft, a second transmission shaft, a third transmission shaft, a first umbrella gear, a second umbrella gear, a third umbrella gear, a fourth umbrella gear, a fifth umbrella gear and a sixth umbrella gear; first, the power motor drives the rotating shaft to rotate at a certain speed and low speed under the action of the reducer, and under the action of the first umbrella gear and the second umbrella gear, the first transmission shaft also rotates, and the third umbrella gear on the first transmission shaft also rotates, and drives the second transmission shaft on the connecting seat to rotate, and then the fifth umbrella gear on the second transmission shaft drives the sixth umbrella gear. Because the sixth umbrella gear is connected to the third transmission shaft, and the third transmission shaft is connected to the Huff disk, the rotation of the Huff disk is realized under multi-stage transmission. Of course, more importantly, the rotation between the Huff disk and the articulated seat is realized through the first umbrella gear and the second umbrella gear.

The present invention is further configured as follows: the second power assembly includes a cylinder seat fixedly connected to the upper end of the connecting seat side and a lifting cylinder arranged on the cylinder seat; the upper end of the third transmission shaft is a spline end, a spline sleeve is provided on the spline end, the sixth bevel gear is arranged on the spline sleeve, and the piston rod end of the lifting cylinder is rotatably connected to the spline end.

By adopting the above technical solution, of course, since the Huff disk also needs to be driven by the second power assembly to move up and down, that is, to lift and lower; for this reason, the present invention also improves the transmission mode of the second power assembly, that is, a lifting cylinder is used to drive the Huff disk to lift and lower, wherein the upper end of the third transmission shaft is set as a spline end, that is, the outer surface has a plurality of splines evenly distributed circumferentially, and then a spline sleeve that meshes with each other is sleeved on the outer wall of the spline end, and the sixth umbrella gear is connected to the spline sleeve, so that the spline sleeve and the sixth umbrella gear can rotate, but cannot move up and down, for this reason, a positioning part is provided to limit the spline sleeve. A radially inwardly arranged annular groove is provided on the outer wall of the spline sleeve, and the positioning part includes a positioning seat arranged on the mounting plate and two positioning side plates arranged on the positioning seat, and the opposite ends of the two positioning side plates have a guide wheel arranged to rotate, and the two guide wheels are arranged in a rolling manner in the annular groove. Since the spline sleeve needs to rotate continuously when the machine is working, in order to reduce friction and increase the service life of the spline sleeve, the spline sleeve is limited by rolling friction.

The present invention is further configured as follows: the yarn feeding assembly includes a yarn guide seat, a shuttle arranged on the yarn guide seat, and a fourth power assembly, the shuttles are multiple and arranged side by side, the fourth power assembly is used to drive a single shuttle to rotate downward or reset, or two or more shuttles to rotate downward or reset at the same time, and is characterized in that: in the initial stage of the shuttle, one end of the shuttle having the wire feed hole is tilted upward, and the fourth power assembly drives the shuttle to a motion state in which the end of the shuttle having the wire feed hole rotates downward to the lowest point and then continues to move forward a certain distance or resets.

By adopting the above-mentioned technical scheme, some current yarn feeding assemblies have the problem of needle blocking, which leads to the need to frequently replace the hook needle. The needle blocking is actually caused by the influence of the trajectory of the shuttle. For this reason, the present invention improves the yarn feeding assembly, and drives the shuttle to rotate to the lowest point through the fourth power assembly, and then drives it forward for a certain distance. Through the forward distance, it cooperates with the hook needle in a horizontal insertion manner, thereby greatly reducing the possibility of needle collision and effectively improving the service life of the hook needle and the shuttle.

The present invention is further configured as follows: the yarn guide seat includes two side plates distributed on the left and right, and the plurality of shuttles are arranged between the two side plates. The shuttle is in a W shape, and is divided into a limiting part at one end, a connecting part in the middle, and a line-inlet part at the other end. A limiting slot hole penetrating through both side ends of the limiting part is provided below the side surface thereof. A first limiting guide post, a second limiting guide post, and a third limiting guide post are connected between the two side plates. The first limiting guide post is arranged to pass through the limiting slot hole on each of the shuttles, and the outer wall of the second limiting guide post contacts or presses against the limiting slot hole on each shuttle. The upper connection of the part and the connecting part is arranged, the outer wall of the third limiting guide column is in contact with or pressed against the rear side surface of the limiting part on each shuttle, there is a certain distance between the limiting slot and the first limiting guide column, and the distances between the second limiting guide column and the third limiting guide column and the bottom of the yarn guide seat are greater than the distance between the first limiting guide column and the yarn guide seat; the limiting part is pushed toward one end of the thread feeding part of the shuttle, and after the shuttle rotates a certain angle with the first limiting guide column as the rotation point, the shuttle is moved forward a certain distance under the guidance of the distance between the limiting slot and the first limiting guide column.

By adopting the above technical scheme, traditional shuttles are hinged on the yarn guide seat. In order to be able to change its travel path, the present invention sets the shuttle in a W shape, and limits the shuttle by means of the first limiting guide post, the second limiting guide post and the third limiting guide post. After the first limiting guide post is embedded in the limiting slot on the shuttle, there is a certain distance between the first limiting guide post and the limiting slot, so that the travel path of the shuttle is possible to rotate-move forward. Under the action of the fourth power component, the shuttle first rotates with the first limiting guide post as the rotating axis. During this process, the second limiting guide post rolls on the surface of the limiting part of the shuttle, and the third limiting guide post detaches from the limiting part. After rotating to the lowest point, the first limiting guide post moves in the limiting slot and stops when the first limiting guide post moves to the other end of the limiting slot. When resetting is required, the fourth power component can be used for reverse movement.

The present invention is further configured as follows: a front thread hole and a rear thread hole are provided on the thread feeding part of the shuttle, and the yarn feeding assembly further comprises a thread blocking assembly for increasing the height of the yarn passing through the front thread hole;

The thread blocking assembly includes a limit seat body, a limit blocking rod, a torsion spring, a transmission block and a transmission sheet. The limit seat body is arranged at the front side of the yarn guide seat. The limit blocking rod is an L-shaped structure and is divided into a limit rod part and a connecting rod part. The limit rod part is transversely arranged below the line feed part of the shuttle and is used to tension the yarn passing through the line feed hole. The connecting rod part passes through the limit seat body and is rotatably connected with the limit seat body.

When one or more of the shuttles rotate downward, after contacting the limit rod, the limit rod is pushed to rotate downward with the connecting rod as the rotating shaft, and the torsion spring is arranged on the protruding end of the connecting rod. After the end of the shuttle slides on the limit rod and detaches from the limit rod, the torsion spring is used to drive the connecting rod to reset; the transmission block is arranged on the protruding end of the connecting rod, the transmission sheet is hinged on the yarn guide seat, and one end of the transmission sheet is close to the upper end surface of the transmission block, and the transmission sheet is controlled by the fourth power assembly to rotate downward or reset;

When the transmission sheet rotates downward, the transmission block and the connecting rod are pushed to rotate simultaneously, so that the limiting rod rotates downward, so that the shuttle that rotates downward and moves forward is not blocked by the limiting rod when resetting.

By adopting the above technical solution, in order to avoid interference between the two bundles of yarn entering the front thread hole and the rear thread hole, the present invention is provided with a thread blocking assembly to increase the height of the yarn passing through the front thread hole;

When the shuttle pushes the limit rod to rotate downward, a large external noise will occur, and the friction between the two is relatively serious. In this regard, the fourth power component is used to control the operation of the thread blocking component. Its working method is as follows:

The fourth power component first drives the transmission plate to rotate, so that the transmission block drives the connecting rod and the limit rod to rotate downward, and then the fourth power component drives one or more of the shuttles to rotate and move forward. Then the fourth power component controls the connecting rod and the limit rod to reset. During the resetting process of the limit rod, the yarn entering the forward line hole will be pulled outward to avoid interference.

The present invention is further configured as follows: the first power component includes a transmission rack, which is arc-shaped and arranged on the outer wall of the hood; a motor, whose output shaft is arranged upward on the outside of the hood; and a transmission gear, which is arranged on the output shaft of the motor and meshes with the transmission rack; the motor rotates forward or reversely to drive the hood to swing circumferentially.

By adopting the above technical solution, since some cut yarn ends will remain on the syringe during the operation of the machine, most of the yarn ends will be sucked out through the air suction port on the half disk, and a very small part will remain on the syringe, which is easy to clog the syringe after a long time, so it needs to be cleaned regularly. At present, the circumferential swing of the scissor cover is controlled by pneumatic means. When the syringe is seriously clogged, it cannot be known in time, and can only be handled by regular cleaning. However, when the syringe is seriously clogged, it will affect the hook needle on it, causing the equipment to be stuck and hit the needle, and in severe cases, the syringe will be damaged. To this end, the present invention improves the first power component, using a motor to drive the transmission gear to rotate, and drives the transmission rack connected to the scissor cover to rotate, thereby driving the scissor cover and the syringe to rotate.

The present invention is further configured as follows: the first power component also includes a controller, the controller includes a detection module, which is used to detect the torque of the motor when it moves, and convert the signal and send it to the PLC control module; the PLC control module is used to control the operating state of the motor, and change the operating state of the motor according to the torque signal sent by the detection module; and an alarm module, which is electrically connected to the PLC control module; when the torque signal detected by the detection module is greater than a preset threshold, the PLC control module turns off the motor and starts the alarm module to make it sound an alarm.

By adopting the above technical solution, in order to serve as an alarm, a detection module for detecting the motor torque and an alarm module are provided. When the motor torque gradually increases to and exceeds the preset threshold, it indicates that the syringe is blocked. At this time, the motor is turned off by the PLC control module, and the alarm module is started to sound an alarm, thereby reminding the staff to clean the syringe in time.

The beneficial effects of the present invention are:

1. In order to be able to observe the internal situation of the machine at any time, it is necessary to be able to open the machine head at any time, that is, to separate the Huff disk from the syringe. To solve this technical problem, the present invention is provided with a support seat and a mounting ring, and the Huff disk and the mounting ring are hinged on the support seat, and the yarn feeding assembly is installed on the mounting ring, so that the machine can be separated from the syringe by flipping the mounting ring or the Huff disk without stopping, thereby facilitating the staff to observe the internal situation of the machine.

2. In order to achieve flipping, the present invention improves the transmission mode of the third power component for driving the Huff disk to rotate, which mainly includes an articulated seat, a connecting seat, a power motor, a rotating shaft, a first transmission shaft, a second transmission shaft, a third transmission shaft, a first umbrella gear, a second umbrella gear, a third umbrella gear, a fourth umbrella gear, a fifth umbrella gear and a sixth umbrella gear; first, the power motor drives the rotating shaft to rotate at a certain speed and low speed under the action of the reducer, and under the action of the first umbrella gear and the second umbrella gear, the first transmission shaft also rotates, and the third umbrella gear on the first transmission shaft also rotates, and drives the second transmission shaft on the connecting seat to rotate, and then the fifth umbrella gear on the second transmission shaft drives the sixth umbrella gear. Because the sixth umbrella gear is connected to the third transmission shaft, and the third transmission shaft is connected to the Huff disk, the rotation of the Huff disk is realized under multi-stage transmission. Of course, more importantly, the rotation between the Huff disk and the articulated seat is realized through the first umbrella gear and the second umbrella gear.

3. The present invention also improves the transmission mode of the second power assembly, that is, a lifting cylinder is used to drive the half plate to lift, wherein the upper end of the third transmission shaft is set as a spline end, that is, the outer surface has a plurality of splines evenly distributed in the circumferential direction, and then a spline sleeve that meshes with each other is sleeved on the outer wall of the spline end, and the sixth bevel gear is connected to the spline sleeve;

In order to ensure that the spline sleeve and the sixth bevel gear can rotate but cannot move up and down, a positioning part is provided to limit the position of the spline sleeve. A radially inwardly arranged annular groove is provided on the outer wall of the spline sleeve, and the positioning part includes a positioning seat arranged on the mounting plate and two positioning side plates arranged on the positioning seat. The two positioning side plates have guide wheels arranged for rotation at opposite ends, and the two guide wheels are arranged in the annular groove for rolling. Since the spline sleeve needs to rotate continuously when the machine is working, in order to reduce friction and increase the service life of the spline sleeve, the spline sleeve is limited by rolling friction.

4. Some current yarn feeding assemblies have the problem of needle blocking, which leads to the need to frequently replace the hook needle. The needle blocking is actually caused by the movement trajectory of the shuttle. For this reason, the present invention provides a yarn feeding assembly, which drives the shuttle to rotate to the lowest point through the fourth power assembly, and then drives it to move forward a certain distance. Through the forward distance, it cooperates with the hook needle in a horizontal insertion manner, thereby greatly reducing the possibility of needle collision and effectively improving the service life of the hook needle and the shuttle.

5. During the operation of the machine, some cut yarn ends will remain on the syringe. Most of the yarn ends will be sucked out through the air suction port on the half disk, and a small part will remain on the syringe. After a long time, the syringe is easily blocked. Therefore, it needs to be cleaned regularly. At present, the circumferential swing of the hood is controlled by pneumatic means. When the syringe is seriously blocked, it cannot be known in time and can only be handled by regular cleaning. However, when the syringe is seriously blocked, it will affect the hook needle on it, causing the equipment to be blocked and hit the needle, and in severe cases, the syringe will be damaged. To this end, the present invention improves the first power component, using a motor to drive the transmission gear to rotate, and drives the transmission rack connected to the hood to rotate, thereby driving the hood and the syringe to rotate.

The first umbrella gear 87 is arranged on the protruding end of the upper end of the rotating shaft 83; the lower end of the first transmission shaft 84 passes through the articulated seat 81 and leads to the first umbrella gear 87, and the second umbrella gear 88 is arranged at the lower end of the first transmission shaft 84 and meshes with the first umbrella gear 87 , the upper end of the first transmission shaft 84 is rotatably connected to the connecting seat 82, and the third bevel gear 89 is arranged on the upper side of the first transmission shaft 84; the second transmission shaft 85 is located in the connecting seat 82, and both ends extend out of the connecting seat 82 respectively, the fourth bevel gear 891 is arranged at one end of the second transmission shaft 85 and meshes with the third bevel gear 89, and the fifth bevel gear 892 is arranged on the other end of the second transmission shaft 85; a mounting plate 821 is also arranged on the side of the connecting seat 82 away from the first transmission shaft 84, the third transmission shaft 86 is rotatably connected to the mounting plate 821, the sixth bevel gear 893 is arranged on the third transmission shaft 86, and the lower end of the third transmission shaft 86 extends downward to the half plate 4;

By rotating the hinge seat 81, the half plate 4 rotates toward or away from the sinker cover 3, and the number of meshing teeth between the first bevel gear 87 and the second bevel gear 88 increases or decreases.

In order to achieve flipping, the present invention improves the transmission mode of the third power assembly 8 for driving the Huff disk 4 to rotate, which mainly includes an articulated seat 81, a connecting seat 82, a power motor (not shown in the figure), a rotating shaft 83, a first transmission shaft 84, a second transmission shaft 85, a third transmission shaft 86, a first umbrella gear 87, a second umbrella gear 88, a third umbrella gear 89, a fourth umbrella gear 891, a fifth umbrella gear 892 and a sixth umbrella gear 893; first, the power motor drives the rotating shaft 83 to rotate at a certain speed and at a low speed under the action of the reducer, and the first umbrella gear 87 and the third umbrella gear 88 are connected to each other. Under the action of the second umbrella gear 88, the first transmission shaft 84 also rotates, and the third umbrella gear 89 on the first transmission shaft 84 also rotates, and drives the second transmission shaft 85 on the connecting seat 82 to rotate, and then the fifth umbrella gear 892 on the second transmission shaft 85 drives the sixth umbrella gear 893. Since the sixth umbrella gear 893 is connected to the third transmission shaft 86, and the third transmission shaft 86 is connected to the half disk 4, the rotation of the half disk 4 is realized under multi-stage transmission. Of course, more importantly, the rotation between the half disk 4 and the articulated seat 81 is realized through the first umbrella gear 87 and the second umbrella gear 88.

As shown in Fig. 2 and Fig. 4, in order to make the half plate 4 cover the mounting ring 12 stably, a second supporting portion 1221 is provided at the upper end of the first limiting portion 122, and a second limiting portion 8211 for supporting the half plate 4 when the half plate 4 covers the mounting ring 12 is provided on the outer wall of the mounting plate 821. The second limiting portion 8211 can not only play a stabilizing role, but also can drive the half plate 4 to flip by pushing the second limiting portion 8211 upwards, which is very convenient.

As shown in Figures 4, 5 and 6, the second power assembly 7 of the present invention includes a cylinder seat 71 fixedly connected to the upper end of the connecting seat 82 and a lifting cylinder 72 arranged on the cylinder seat 71; the upper end of the third transmission shaft 86 is a spline end 861, and a spline sleeve 862 is sleeved on the spline end 861. The sixth umbrella gear 893 is arranged on the spline sleeve 862, and the piston rod end of the lifting cylinder 72 is rotatably connected to the spline end 861.

Of course, since the Huff disk 4 also needs to be driven by the second power assembly 7 to move up and down, that is, to be lifted and lowered; for this reason, the present invention also improves the transmission method of the second power assembly 7, that is, a lifting cylinder 72 is used to drive the Huff disk 4 to lift and lower, wherein the upper end of the third transmission shaft 86 is set to a spline end 861, that is, the outer surface has a plurality of splines evenly distributed circumferentially, and then a spline sleeve 862 that meshes with each other is sleeved on the outer wall of the spline end 861, and the sixth umbrella gear 893 is connected to the spline sleeve 862, so that the spline sleeve 862 and the sixth umbrella gear 893 can rotate but cannot move up and down, for this reason, a positioning portion is provided to limit the spline sleeve 862. A radially inward annular groove is provided on the outer wall of the spline sleeve 862, and the positioning portion includes a positioning seat 8212 arranged on the mounting plate 821, two positioning side plates 8213 arranged on the positioning seat 8212, and guide wheels 8214 are rotatably arranged at opposite ends of the two positioning side plates 8213. The two guide wheels 8214 are rollingly arranged in the annular groove. When the machine is working, the spline sleeve 862 needs to rotate continuously. In order to reduce friction and increase the service life of the spline sleeve 862, the spline sleeve 862 is limited by rolling friction.

As shown in Figure 7, the yarn feeding assembly 5 of the present invention includes a yarn guide seat 51, a shuttle 52 and a fourth power assembly 53 arranged on the yarn guide seat 51. There are multiple shuttles 52 and they are arranged side by side. The fourth power assembly 53 is used to drive a single shuttle 52 to rotate downward or reset, or two or more shuttles 52 to rotate downward or reset at the same time. In the initial stage of the shuttle 52, the end with the wire feed hole is tilted upward. The fourth power assembly 53 drives the shuttle 52 to move in a state where the end of the shuttle 52 with the wire feed hole rotates downward to the lowest point and then continues to move forward for a distance or resets.

Some of the current yarn feeding assemblies 5 have the problem of needle blocking, which requires frequent replacement of the hook needle 21. The needle blocking is actually affected by the trajectory of the shuttle 52. For this reason, the present invention provides a yarn feeding assembly 5, which drives the shuttle 52 to rotate to the lowest point through the fourth power assembly 53, and then drives it forward a certain distance. Through the forward distance, it cooperates with the hook needle 21 in a horizontal insertion manner, thereby greatly reducing the possibility of needle collision and effectively improving the service life of the hook needle 21 and the shuttle 52.

As shown in Figures 7, 8 and 9, the yarn guide seat 51 of the present invention includes two side plates 511 distributed on the left and right, and multiple shuttles 52 are arranged between the two side plates 511. The shuttle 52 is W-shaped, divided into a limiting part 521 at one end, a connecting part 522 in the middle and a line-inlet part 523 at the other end. A limiting slot 524 is provided on the lower side of the limiting part 521 and passes through its two side ends. A first limiting guide column 512, a second limiting guide column 513 and a third limiting guide column 514 are connected between the two side plates 511. The first limiting guide column 512 is arranged to pass through the limiting slot 524 on each shuttle 52, and the outer wall of the second limiting guide column 513 contacts or presses against the limiting part on each shuttle 52. The upper connection between the part 521 and the connecting part 522 is arranged, the outer wall of the third limiting guide post 514 is in contact with or pressed against the rear side surface of the limiting part 521 on each shuttle 52, there is a certain distance between the limiting slot hole 524 and the first limiting guide post 512, and the distance between the second limiting guide post 513 and the third limiting guide post 514 and the bottom of the yarn guide seat 51 is greater than the distance between the first limiting guide post 512 and the yarn guide seat 51; the limiting part 521 is pushed toward one end of the inlet part 523 of the shuttle 52, and after the shuttle 52 rotates a certain angle with the first limiting guide post 512 as the rotation point, the shuttle 52 is moved forward a certain distance under the guidance of the distance between the limiting slot hole 524 and the first limiting guide post 512.

The conventional shuttle 52 is hinged on the yarn guide seat 51. In order to change its path, the present invention sets the shuttle 52 in a W shape, and limits the shuttle 52 by means of the first limiting guide post 512, the second limiting guide post 513 and the third limiting guide post 514. After the first limiting guide post 512 is embedded in the limiting slot 524 on the shuttle 52, there is a certain distance between the first limiting guide post 512 and the limiting slot 524, so that the path of the shuttle 52 is rotation-forward movement. Possibly, under the action of the fourth power assembly 53, the shuttle 52 first rotates with the first limit guide column 512 as the rotating axis. During this process, the second limit guide column 513 rolls on the surface of the limit part 521 of the shuttle 52, and the third limit guide column 514 detaches from the limit part 521. After rotating to the lowest point, the first limit guide column 512 moves in the limit slot 524, and stops when the first limit guide column 512 moves to the other end of the limit slot 524; when resetting is required, the fourth power assembly 53 can be used for reverse movement.

As shown in Figures 8 and 9, a first concave arc surface 525 is provided at the upper connection between the limiting part 521 and the connecting part 522 of the present invention. When the shuttle 52 moves forward to the extreme end, a second concave arc surface 526 is provided at the position where the second limiting guide column 513 abuts against or presses against the limiting part 521, and an arc-shaped guide surface 527 protruding outward is also provided between the first concave arc surface 525 and the second concave arc surface 526 of the limiting part 521; when the shuttle 52 rotates, the second limiting guide column 513 disengages from the first concave arc surface 525 and slides on the arc-shaped guide surface 527; when the shuttle 52 moves forward, the second limiting guide column 513 slides from the end of the arc-shaped guide surface 527 to the second concave arc surface 526.

In order to enable the second limiting guide column 513 to slide smoothly on the limiting part 521 of the shuttle 52, a first concave arc surface 525, a second concave arc surface 526 and an arc-shaped guide surface 527 are provided. In the initial stage, the second limiting guide column 513 is adapted on the first concave arc surface 525. During movement, the second limiting guide column 513 first slides on the arc-shaped guide surface 527 and then slides onto the second concave arc surface 526, thereby reducing the friction between the second limiting guide column 513 and the shuttle 52 and improving the service life of the shuttle 52.

As shown in FIG9 and FIG10, the thread feeding portion 523 of the shuttle 52 of the present invention has a front thread hole 528 and a rear thread hole 529, and the yarn feeding assembly 5 further includes a thread blocking assembly 54 for increasing the height of the yarn passing through the front thread hole 528;

As shown in FIG11 , the thread blocking assembly 54 includes a limiting seat body 541, a limiting blocking rod 542, a torsion spring 543, a transmission block 544 and a transmission sheet 545. The limiting seat body 541 is arranged at the front side of the yarn guide seat 51. The limiting blocking rod 542 is an L-shaped structure and is divided into a limiting rod portion 5421 and a connecting rod portion 5422. The limiting rod portion 5421 is transversely arranged below the line feed portion 523 of the shuttle 52 and is used to tension the yarn passing through the forward line hole 528. The connecting rod portion 5422 passes through the limiting seat body 541 and is rotatably connected to the limiting seat body 541.

When one or more shuttles 52 rotate downward, after contacting the limiting rod 5421, the connecting rod 5422 is used as a rotating shaft to push the limiting rod 5421 to rotate downward. The torsion spring 543 is arranged on the protruding end of the connecting rod 5422. After the end of the shuttle 52 slides on the limiting rod 5421 and disengages from the limiting rod 5421, the torsion spring 543 is used to drive the connecting rod 5422 to reset. The transmission block 544 is arranged on the protruding end of the connecting rod 5422. The transmission sheet 545 is hinged on the yarn guide seat 51, and one end thereof is close to the upper end surface of the transmission block 544. The transmission sheet 545 is controlled by the fourth power assembly 53 to rotate downward or reset.

When the transmission sheet 545 rotates downward, the transmission block 544 and the connecting rod 5422 are pushed to rotate simultaneously, so that the limiting rod 5421 rotates downward, so that the shuttle 52 that rotates downward and moves forward is not blocked by the limiting rod 5421 when resetting.

In order to avoid interference between the two bundles of yarn entering the front thread hole 528 and the rear thread hole 529, the present invention is provided with a thread blocking assembly 54 to increase the height of the yarn passing through the front thread hole 528;

When the shuttle 52 pushes the limit rod 5421 to rotate downward, a large external noise will occur, and the friction between the two is relatively serious. In this regard, the fourth power component 53 is used to control the operation of the line blocking component 54. Its working method is as follows:

The fourth power assembly 53 first drives the transmission plate 545 to rotate, so that the transmission block 544 drives the connecting rod 5422 and the limiting rod 5421 to rotate downward, and then the fourth power assembly 53 drives one or more of the shuttles 52 to rotate and move forward. Then, the fourth power assembly 53 controls the connecting rod 5422 and the limiting rod 5421 to reset. During the resetting process of the limiting rod 5421, the yarn entering the forward line hole 528 will be pulled outward to avoid interference.

As shown in FIG. 8 and FIG. 10 , the fourth power assembly 53 of the present invention includes

The cylinder group 531 is arranged at the rear side of the two side plates 511 and at the rear side of the shuttle 52. The cylinder group 531 has piston rods that are the same in number as the shuttles 52 and the transmission plates 545. The extended end of one of the piston rods corresponds to the upper rear end of the transmission plate 545, and the extended ends of the remaining piston rods correspond to the upper rear ends of the limiting parts 521 on the shuttles 52. The corresponding shuttle 52 or the transmission plate 545 is pushed to move by controlling the extension of each piston rod.

And a spring group 532, the spring group 532 has tension springs 5321 that are the same in number as the shuttles 52 and the transmission plates 545, and a pull rod 5322 is also provided between the two side plates 511 and located at the lower rear side thereof, one end of each tension spring 5321 is connected to the pull rod 5322, the other end of one of the tension springs 5321 is connected to the lower rear end of the transmission plate 545, and the other ends of the remaining tension springs 5321 are respectively connected to the lower rear ends of the limiting parts 521 of each shuttle 52, and are used to pull the corresponding shuttle 52 or the transmission plate 545 back and reset after the piston rod on the cylinder group 531 retracts.

In order to be able to control each shuttle 52 and the transmission plate 545, the present invention adopts pneumatic driving and resets it by the tension of the tension spring 5321; that is, the cylinder group 531 drives the shuttle 52 to flip, and after reaching the horizontal position, it moves forward, so that the thread-inlet part 523 of the shuttle 52 is embedded in the needle hole of the hook needle 23. When resetting, the cylinder group 531 retracts, and at the same time the tension spring 5321 pulls the shuttle 52, so that the thread-inlet part 523 is out of the needle hole of the hook needle 21, and then flips it, which is very convenient and practical.

Since the resetting of the shuttle 52 is controlled by the tension of the tension spring 5321, it is unstable to limit the shuttle 52 only by the second limit guide column 513 and the third limit guide column 514. For this reason, as shown in Figures 8 and 10, a fourth limit guide column 515 is also provided between the two side plates 511. The fourth limit guide column 515 is located above the shuttle 52. After the shuttle 52 is reset, the connecting part 522 on the shuttle 52 is pressed against the fourth limit guide column 515.

Regarding the position where the shuttle 52 rotates downward to the lowest point, in fact, its line-inlet part 523 rotates from an upwardly tilted state to a horizontal state. In order to achieve precise control, a limit assembly 516 is provided for this purpose. As shown in FIGS. 8, 10 and 12, the limit assembly 516 includes a first limit shaft 5161, a second limit shaft 5162, a limit block 5163 and an adjustable limit bolt 5164; the number of shuttles 52 can generally be set to five, and the limit assembly 516 can also be adjusted to The transmission sheet 545 is controlled, so the limit block 5163 can be set to six pieces. The first limit shaft 5161 and the second limit shaft 5162 are both arranged on the two side plates 511, and both are located above the shuttle 52. A through hole is opened at one end of the limit block 5163, and it is rotatably connected with the first limit shaft 5161 through the through hole. The second limit shaft 5162 is located below the limit block 5163. The lower end surface of the limit block 5163 is an inclined surface. After being stable under the action of gravity, the second limit The positioning shaft 5162 supports the bottom of the limit block 5163, one of the limit blocks 5163 is opposite to the transmission sheet 545, and the other is opposite to the limit portion 521 on each shuttle 52. A cover plate 517 is provided at the upper end of the two side plates 511. There are six limit bolts 5164, which are arranged on the cover plate 517 in a threaded connection manner. After passing through the cover plate 517, the lower ends of the limit bolts 5164 are respectively opposite to the upper end faces of the limit blocks 5163. When the limit blocks 5163 are away from the second limit axis, the limit bolts 5164 are connected to the upper end faces of the limit blocks 5163. After rotating a certain angle in the direction of 5162, the upper end surface of the limit block 5163 is pressed against the bottom of the limit bolt 5164, which is used to limit the limit block 5163 from continuing to rotate; during the rotation and forward movement of the shuttle 52, its limit part 521 gradually approaches the limit block 5163 and pushes the limit block 5163 to rotate along the second limit axis 5162. After the upper end surface of the limit block 5163 is pressed against the corresponding limit bolt 5164, it indicates that the shuttle 52 has rotated to the lowest point.

Optimally, as shown in Figure 7, a threading baffle 55 is also provided on the yarn guide seat 51, and the threading baffle 55 is located obliquely above the inlet portion 523 of the shuttle 52. By arranging the threading baffle 55, each bundle of yarn is constrained to avoid interference.

As shown in FIG13 , the first power assembly 6 of the present invention includes a transmission rack 61, which is arc-shaped and disposed on the outer wall of the hood 3; a motor 62, whose output shaft is disposed upward on the outer side of the hood 3; and a transmission gear 63, which is disposed on the output shaft of the motor 62 and meshes with the transmission rack 61; the motor 62 rotates forward or reversely to drive the hood 3 to swing circumferentially.

During the operation of the machine, some cut yarn ends will remain on the syringe 2, most of which will be sucked out through the air suction port on the half disk 4, and a small part will remain on the syringe 2, which will easily block the syringe 2 after a long time, so it needs to be cleaned regularly. At present, the circumferential swing of the scissor cover 3 is controlled by pneumatic means. When the syringe 2 is seriously blocked, it cannot be known in time, and can only be handled by regular cleaning. However, when the syringe 2 is seriously blocked, it will affect the hook needle 21 thereon, causing the equipment to be blocked and hit the needle, and in severe cases, the syringe will be damaged. For this reason, the present invention improves the first power assembly 6, and uses a motor 62 to drive the transmission gear 63 to rotate, and drives the transmission rack 61 connected to the scissor cover 3 to rotate, thereby driving the scissor cover 3 to rotate.

As shown in Figure 14, the first power component 6 of the present invention also includes a controller 64, which includes a detection module 641, which is used to detect the torque of the motor 62 when it moves, and convert the signal and send it to the PLC control module 624; the PLC control module 624 is used to control the operating state of the motor 62, and change the operating state of the motor 62 according to the torque signal sent by the detection module 641; and an alarm module 643, which is electrically connected to the PLC control module 624; when the torque signal detected by the detection module 641 is greater than a preset threshold, the PLC control module 624 turns off the motor 62 and starts the alarm module 643 to make it emit an alarm sound.

In order to serve as an alarm, a detection module 641 for detecting the torque of the motor 62 and an alarm module 643 are provided. When the torque of the motor 62 gradually increases to and exceeds a preset threshold value, the surface syringe 2 has been blocked. At this time, the motor 62 is turned off through the PLC control module 624, and the alarm module 643 is started to sound an alarm, thereby reminding the staff to clean the syringe 2 in time.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
