Some embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

See fig. 1-4;

as shown in fig. 1, the present embodiment provides a lancing apparatus 100 including a first lancing device 200 and a second lancing device 300 sequentially disposed on a transport 400.

The puncture equipment is used for puncturing the puncture material to form holes, so that the absorption efficiency and the infiltration capacity of the disposable sanitary article are improved. The corresponding puncturing device can be actually selected according to the structure of the puncturing material, for example, when the puncturing material is only an absorber, full puncturing is adopted, the used device is the first puncturing device 200, and if the puncturing material is a combination of the absorber, the surface layer and the bottom film, half puncturing is adopted, namely, the puncturing depth needs to be controlled. The lancing apparatus employed at this time is a second lancing apparatus 300. Two kinds of punctures may be performed simultaneously in the puncture device 100.

The first piercing apparatus 200 includes a first roller 210, a first piercing assembly 220 for piercing material, and a first compacting apparatus 230 for compacting the pierced material. The first roller 210 is disposed at one side of the transporting device 400 and is selectively connected to the transporting device 400. The first puncture assembly 220 and the first pressing apparatus 230 are both detachably connected to the first roller 210 along the outer circumference of the first roller 210.

The first roller 210 provides the necessary installation space for the piercing assembly, the first compaction apparatus 230. The first roller 210 is a cylinder, so that the structure of the puncturing device 100 is simplified, meanwhile, the puncturing material is convenient to squeeze immediately after puncturing, and the integrity of the puncturing material structure is ensured. The first roller 210 is disposed at a side near the transporting device 400 for transporting and can selectively act on the surface of the transporting device 400 for transporting the puncture material.

It should be noted that, when the first roller 210 can realize piercing and compacting at the same time, the speed of transporting the piercing material is slow, and the speed of rotating the first roller 210 is fast, so that after piercing, the displacement of the piercing material is small, even basically unchanged, and then the piercing material is immediately extruded. The time difference between the pressing and the puncturing can be controlled by adjusting the relative values of the rotation speed and the transport speed of the first roller 210, thereby ensuring that the puncturing and the pressing can be performed rapidly.

The first puncture assembly 220 is detachably connected with the first roller 210, so that the application range of the first puncture device 200 is wider, the first puncture assembly 220 can be replaced according to production requirements, or the shape of the first puncture assembly 220 is changed, the production cost is reduced, and meanwhile, the maintenance cost of the puncture device 100 is reduced.

Further, first piercing assembly 220 includes a first piercing member 221 and a second piercing member 223. The first piercing member 221 and the second piercing member 223 are detachably connected to the first roller 210 in the circumferential direction of the first roller 210. The first piercing member 221 and the second piercing member 223 are spaced apart from the first compacting apparatus 230.

When the puncture material is transported to the lower side of the first roller 210, the first puncture member 221 or the second puncture member 223 acts on the puncture material to puncture the puncture material, and the puncture material is immediately fixed by the first pressing device 230 after the puncture is completed. The first pressing device 230 is arranged between the first piercing member 221 and the second piercing member 223 at intervals, so that the piercing material can be pressed immediately after being pierced, and the structural integrity of the piercing material is further ensured.

It should be noted that the number of piercing elements provided on the first roller 210 is not limited to two, and may be increased appropriately according to the production requirement. Meanwhile, the distance between the first piercing member 221 and the second piercing member 223 may be appropriately set according to actual production requirements, for example, the first piercing member 221 and the second piercing member 223 may be disposed opposite to each other or spaced apart by a fixed distance.

Further, the first puncture member 221 includes a plurality of puncture needles 222, and the plurality of puncture needles 222 are wound around the circumference of the first roller 210 and are interference fit with the first roller 210.

Further, referring to fig. 2, a plurality of mounting members 211 are disposed on the circumferential surface of the first roller 210, and the plurality of puncture needles 222 are in interference fit with the plurality of mounting members 211, so that the puncture needles 222 and the first roller 210 can be firmly connected together, and meanwhile, when the puncture needles 222 need to be disassembled, the puncture needles 222 and the first roller 210 can be separated. The interference fit can enhance the connection force between the puncture needle 222 and the first roller 210, so that the possibility of sliding of the puncture needle 222 can be reduced when the puncture needle 222 acts on the puncture material, and the accuracy and the integrity of the punctured graph are ensured.

Further, each lancet 222 includes a connector 224 and a lancet body 226. The connecting member 224 is connected to one end of the lancet body 226, and the connecting member 224 is selectively connected to the first roller 210. And a plurality of mounting members 211 are provided on the circumferential surface of the first roller 210, and the plurality of mounting members 211 are selectively connected with the connecting member 224. And each of the mounting pieces 211 includes a first protrusion 213, a second protrusion 215, and a connection hole 217. The first protrusion 213 and the second protrusion 215 are both in communication with the connection hole 217, the first protrusion 213 and the second protrusion 215 are disposed opposite to each other, and both ends of the first protrusion 213 and the second protrusion 215 and the connection piece 224 can be selectively connected.

When the puncture needle 222 needs to be fixed to the first roller 210, the two ends of the connecting piece 224 are disposed in the first protruding portion 213 and the second protruding portion 215, and the first protruding portion 213 and the second protruding portion 215 prevent the connecting piece 224 from sliding, so as to fix the puncture needle 222. The connecting piece 224 is generally made of a material with a certain elasticity, such as rubber or latex, so that the connecting piece 224 can be smoothly placed into the mounting piece 211, and meanwhile, the connecting piece 224 can be relatively easily pulled out, so that the first puncture piece 221 can be replaced or the shape in the first puncture piece 221 can be changed conveniently, and the industrial production scale can be enlarged conveniently.

The second puncture member 223 and the first roller 210 are connected in the same manner as the first puncture member 221 and the first roller 210. Meanwhile, besides the interference fit disclosed by the invention, the connection mode of the puncture needle 222 in the first puncture member 221 and the first roller 210 can also adopt magnetic connection, namely, a magnetic iron sheet is arranged at one end of the puncture needle 222 connected with the first roller 210, the surface of the first roller 210 is also provided with a magnetic surface, and then the puncture needle 222 and the first roller 210 can be connected together through magnetic force, so that the technical problems that the shape of a puncture material is fixed and cannot be changed at will due to the fixed position of the puncture needle 222 on the puncture device 100 can be solved.

Further, referring to fig. 3, the first pressing apparatus 230 includes a first pressing member 231 and a second pressing member 233. The first pressing member 231 and the second pressing member 233 are detachably connected with the first roller 210 along the circumferential direction of the first roller 210, and the first piercing member 221, the first pressing member 231, the second piercing member 223 and the second pressing member 233 are sequentially arranged at intervals along the circumferential direction of the first roller 210.

The first pressing apparatus 230 further includes a first connecting member 232 and a second connecting member 234, one end of the first connecting member 232 is fixedly connected with the first roller 210 through a bolt, the other end of the first connecting member 232 is in bolt connection with one end of the first pressing member 231, one end of the second connecting member 234 is fixedly connected with the first roller 210 through a bolt, and the other end of the second connecting member 234 is in bolt connection with the other end of the first pressing member 231. The connection mode of the second pressing member 233 and the first roller 210 is identical to the connection mode of the first pressing member 231 and the first roller 210. When the pressing is required, the first and second connecting

members

232 and 234 are connected with the first roller 210 by bolts and the first pressing member 231, and the pressing is achieved. If the pressing member needs to be replaced, only the two ends of the first pressing member 231 need to be separated from the first connecting member 232 and the second connecting member 234 for replacement. Meanwhile, the positions of the first connecting piece 232 and the second connecting piece 234 connected with the first roller 210 can be adjusted, so that the puncture materials can be compressed in different degrees.

The first piercing member 221, the first pressing member 231, the second piercing member 223 and the second pressing member 233 are sequentially arranged at intervals along the circumferential direction of the first roller 210, so that the piercing material can be immediately pressed after being pierced, repeated piercing or repeated pressing is avoided, and the structural integrity of the piercing material is ensured.

It should be noted that the number of pressing members included in the first pressing device 230 is not limited to two, and may be appropriately increased or decreased according to the production requirements.

Further, the second lancing apparatus 300 includes a second roller 310, a second lancing assembly 320, and a second compaction apparatus 330. The second roller 310 is provided at one side of the transporting device 400 and is selectively connected to the transporting device 400, and the second penetration assembly 320 and the second pressing apparatus 330 are detachably connected to the second roller 310 along the circumferential direction of the second roller 310. The structures of the second roller 310, the second piercing assembly 320 and the second pressing device 330 are identical to those of the first roller 210, the first piercing assembly 220 and the first pressing device 230, and at the same time, the connection relationship between the second piercing assembly 320 and the second pressing device 330 and the second roller 310 is identical to the connection relationship between the first piercing assembly 220 and the first pressing device 230 and the first roller 210.

Further, the puncturing device 100 further includes a barrier 500 for controlling the puncturing depth of the second puncturing assembly 320, the barrier 500 being disposed around the circumference of the second roller 310 and the second puncturing assembly 320 passing through the barrier 500. The barrier 500 may prevent the second piercing assembly 320 from piercing too far and thereby damaging the structural integrity of the pierced material.

Specifically, the barrier 500 is a foam having elasticity, the foam being annularly disposed around the circumference of the second roller 310, and the thickness of the foam being smaller than the length of the second penetration assembly 320. The barrier 500 is formed of resilient foam, which can act on the piercing assembly to a limited extent when the piercing member pierces the piercing material, preventing the piercing needle 222 from penetrating the piercing material. Meanwhile, the distance between the second roller 310 and the conveying device 400 can be adjusted according to the penetration depth of the penetration needle 222 required by production, so that the action of foam on the penetration assembly can be adjusted, the penetration depth of penetration materials can be adjusted, and the application range of the penetration device 100 can be enlarged.

Further, the transportation device 400 can transport the puncture material, and when the puncture material is punctured, the transportation device 400 can also play a certain supporting role, so that the puncture material is prevented from sliding in the puncturing process, and the accuracy of the puncturing position is ensured.

The power device 420 is connected with the conveyor belt 410, and the first roller 210 and the second roller 310 are both arranged on one side of the conveyor belt 410, which is close to the conveyor belt 410 and used for transporting puncture materials. The power device 420 provides power for the conveyor belt 410 to transport the puncture material. The first roller 210 and the second roller 310 are disposed at one side of the conveyor belt 410 near the conveyor belt 410 for transporting the puncture material, so that the first roller 210 and the second roller 310 are convenient for puncturing the puncture material.

If only the piercing element pierces the piercing material in the piercing apparatus 100, and there is no space for accommodating the piercing element during piercing, the piercing element is liable to penetrate the piercing material, and at the same time, the piercing element may be damaged. While the roller having the accommodating space is disposed on the opposite side of the conveyor belt 410 to the first roller 210 or the second roller 310 in the prior art, the structure is too bulky to maintain or replace the apparatus, and the structure of the puncture needle 222 is more complex.

In this embodiment, a plurality of accommodating holes 411 are formed in the conveyor belt 410, so that the puncture member in the puncture assembly can have a space for puncturing during puncturing. The plurality of receiving holes 411 are selectively connectable with the first and

second spike assemblies

220 and 320. When the puncture member punctures, the puncture material is penetrated by the puncture member and the puncture member penetrates into the accommodating hole 411, so that the puncture member is prevented from being damaged. Meanwhile, the structure of the puncturing device 100 is simplified, the volume of the puncturing device 100 is reduced, and the occupied area of the puncturing device is reduced.

Further, the transporting apparatus further includes a plurality of brackets 413, and the plurality of brackets 413 are connected to the conveyor belt, so as to maintain the tension of the conveyor belt 410, and simultaneously enable the conveyor belt 410 to smoothly convey the puncture material.

Meanwhile, the other ends of the connecting components 415 and the accommodating holes 411 can be matched with each other, so that the position of the puncture member can be limited, and the puncture member is prevented from sliding.

Further, each connection assembly 415 includes a plurality of connection posts 416 and a plurality of sliding plates 417. The plurality of sliding plates 417 are disposed within the plurality of connecting posts 416 and slidably coupled to the plurality of connecting posts 416, and the plurality of connecting posts 416 are slidably coupled to the transportation device 400. Specifically, one connection post 416 corresponds to one sliding plate 417, one sliding plate 417 is disposed in the corresponding one connection post 416, and one end of the connection post 416 is connected to the corresponding one bracket 413, the other end of the connection post 416 is selectively engaged with the corresponding receiving hole 411, and the connection post 416 is selectively connected to the puncture assembly. Further, the length of the connecting post 416 is longer than the lengths of the first and

second spike assemblies

220, 320, i.e., the length of the connecting post 416 is longer than the length of the spike 222.

The sliding plate 417 slides within the connecting post 416, so that the connecting post 416 can accommodate different lengths of the piercing needle 222, thereby expanding the scope of use of the piercing device 100. Meanwhile, when the puncture material is a surface layer, an absorber and a bottom die, the sliding plate 417 can also play a certain role in protecting the bottom die and prevent the puncture material from being penetrated. The connecting column 416 may be a cylinder or a cylinder structure such as a cone.

In this embodiment, the operation method and principle of the puncture device are as follows:

the puncture needle is connected with the first roller and the second roller according to the shape required by production. Meanwhile, the rotation speed of the first roller and the second roller and the speed of the conveyor belt are set. And then the puncture material is put into the conveyor belt for conveying, and the region where the puncture material is to be punctured is placed in a region where a plurality of containing holes are arranged on the conveyor belt. And then transporting the puncture materials, and simultaneously rotating the roller. When the puncture material is transported to the lower part of the roller, the puncture assembly on the roller punctures the puncture material, and the puncture piece in the puncture assembly enters the connecting column, so that the puncture is completed. At this time, if the depth of the puncture material is required, the blocking piece can control the depth of the puncture piece, so that the puncture can be performed, and the integrity of the puncture material structure can be ensured.
