Description

Technical Field

[0001] The present application relates to the technical field of inch-mat cutting, and in particular to an inch-mat cutting device. Background Art

[0002] Inch pads are a commonly used component, which are widely used in many fields such as mechanical manufacturing, electronic equipment, and automobile industry. Among them, in mechanical manufacturing, inch pads are generally used for sealing and cushioning of equipment parts, in electronic equipment, inch pads usually play a role of insulation and shockproof, and in the automobile industry, inch pads are mainly set in key parts of engines and transmissions.

[0003] Typically, in the production of new energy vehicle batteries in the automotive industry, an inch pad is generally used to fit one end of the battery. The inch pad is usually ring-shaped. This inch pad is mainly used to protect the battery and prevent the battery from short circuit or leakage. It is also conducive to heat dissipation and can protect the battery casing from wear.

[0004] Usually, refer to Figure 1 The inch pad is composed of a release film, an adhesive film and an inch pad arranged in sequence. Generally, before production, it is necessary to prepare continuous release film a, adhesive material b and inch pad tape c in advance. Due to storage and transportation issues, the two sides of the adhesive material b are usually affixed with a first protective film b1 and a second protective film b2 respectively. During production, it is necessary to first tear off the first protective film b1 and the second protective film b2 on the adhesive material b, and then stack the release film a, adhesive material b and inch pad tape c in sequence to form a product tape, and then use a cutting device to cut the inch pad on the product tape. Based on the different installation requirements of different batteries, the inch pad needs to have different sizes and different thicknesses.

[0005] The existing cutting device includes a supporting platform for laying the product strip flat, and a driving member and a cutting blade are arranged above the supporting platform. The driving member is driven to drive the cutting blade to move downward quickly to quickly cut out a inch pad on the product strip.

[0006] The cutting blade may adhere to the glue of the sticky film. When cutting, because the cutting blade is too vertical to the product strip, the pressure of the cutting blade on the sticky film is relatively large, which may cause the sticky film to be squeezed to a large extent, and the glue may be squeezed out and adhere to the side wall of the cutting blade. When too much glue adheres, the cutting may be stuck, the cutting accuracy will also decrease, and the cutting efficiency will be affected. Summary of the invention

[0007] In order to reduce the occurrence of the cutting blade adhering to the glue as much as possible, the present application provides a inch pad cutting device.

[0008] The present application provides a inch pad cutting device adopts the following technical solution: A inch-mat cutting device comprises a frame, wherein the frame is equipped with a material preparation and unwinding mechanism, a cutting mechanism and a rewinding mechanism, wherein the material preparation and unwinding mechanism is configured to prepare and unwind product strips, the cutting mechanism is configured to cut inch-mats from the product strips, and the rewinding mechanism is configured to rewind the product strips; The cutting mechanism includes a driving component 1 connected to the frame, the driving component 1 is connected to a frame 1, the frame 1 is installed with a driving component 2, the driving component 2 is connected to a frame 2, the frame 2 is installed with two relatively arranged legs, each of the legs is provided with a cutting blade, and the cutting blade is configured to be able to rotate and be fixed so as to change the angle at which the cutting blade cuts into the product strip; the driving component 2 is configured to be able to drive the two cutting blades to rotate and move simultaneously, wherein the movement trajectory of each of the cutting blades is a spiral line; the frame 2 is also installed with a driving component 3, the driving component 3 is connected to the two legs, each of the legs is rotatably connected to the frame 2, and the driving component 3 is configured to be able to drive the two legs to rotate in opposite directions so that the two cutting blades move away from or close to each other; the frame is also installed with a poking component, which is used to poke the inch pad away from the product strip.

[0009] By adopting the above technical solution, the following actions can be achieved: the material making and unwinding mechanism produces the product strip and the winding mechanism winds it up, and the product strip passes through one side of the cutting mechanism and is cut into a sized pad by the cutting mechanism.

[0010] Since the inch pad is annular, in the present application, the cutting blade needs to cut the product strip twice, specifically, first cutting with a small circle trajectory and then cutting with a large circle trajectory on the product strip. In the present application, the driving component three can drive the two cutting blades to move away from or close to each other, thereby adjusting the size of the circle drawn by the cutting blades to meet the needs of two cuttings; In this regard, take a specific cutting action as an example: driving component 2 drives the two legs to rotate and move simultaneously, thereby driving the two cutting blades to rotate and draw a circle and then cut the product strip.

[0011] Since the movement trajectory of the cutting blade is a spiral line, the pressure on the viscous adhesive material in the product strip is relatively small when the cutting blade cuts the viscous adhesive material, which is equivalent to the cutting blade making continuous circular shallow cuts on the viscous adhesive material, and the adhesive is not easily squeezed out and adheres to the cutting blade.

[0012] The present application can be applied to cutting out inch pads of different sizes and thicknesses. Specifically, different cutting methods can be used for inch pads of different thicknesses and sizes to prevent the glue from adhering to the cutting tool. For product strips with smaller thicknesses, the angle of the cutting blade can be changed to change the angle at which the cutting blade cuts into the product strip to reduce the deformation and extrusion of the sticky rubber pad during the cutting process. This can also reduce the pressure on the sticky rubber material when it is cut. Moreover, since the thickness of the product strip is relatively small, it is usually only necessary to drive the second drive component to drive the two cutting blades to rotate a total of one circle, that is, each of them rotates half a circle to complete the cutting, which ensures processing efficiency. For product strips with larger thicknesses, the above-mentioned spiral trajectory cutting method is usually used.

[0013] Preferably, the driving assembly 2 comprises a housing 1 connected to the frame 1, the housing 1 is rotatably connected to a gear 1, the gear 1 is provided with a connecting hole, the connecting hole is threadedly connected to a linkage column 1, the linkage column 1 is also slidably connected to the frame 1, and the rotation of the gear 1 can drive the linkage column 1 to move; The frame body 1 is also equipped with a driving member, the driving member is connected to a gear 2, and the gear 2 is drivingly connected to the gear 1; The linkage column 1 is rotatably connected to the linkage column 2 and the linkage column 1 and the linkage column 2 can move synchronously, and the linkage column 2 is connected to the frame 2; The frame body 1 is connected to the shell body 2, the shell body 2 is rotatably connected to the gear 3, the gear 3 is transmission-connected to the gear 2, the gear 3 is connected to a transmission column that can rotate together, the linkage column 1 is provided with a receiving hole, the linkage column 2 is provided with a transmission groove connected to the receiving hole, the transmission column is penetrated by the receiving hole, the transmission column has a transmission part at one end close to the linkage column 2, the transmission part is inserted in the transmission groove, the transmission part and the linkage column 2 can rotate synchronously, and when the linkage column 2 moves relative to the transmission column, the transmission part can always drive the transmission groove to rotate, thereby driving the linkage column 2 to rotate.

[0014] By adopting the above technical solution, the driving driving member can drive gear 2 to rotate, thereby driving gear 1 and gear 3 to rotate at the same time, wherein the rotation of gear 1 will drive the linkage column 1 to move, thereby driving the linkage column 2 to move, and the rotation of gear 3 will drive the transmission column to rotate, thereby driving the linkage column 2 to rotate through the transmission part. The above realizes the relatively stable rotation and movement of the linkage column 2, and the cutting feed amount of the cutting blade is stable.

[0015] Preferably, the driving component three includes a transmission rod one, one end of the transmission rod one is hinged to the frame body two, and the other end is hinged to the transmission rod two, and the end of the transmission rod two away from the transmission rod one is hinged to one of its legs; a transmission rod three is hinged to the middle position of the transmission rod one, and the end of the transmission rod three away from the transmission rod one is hinged to the other leg; the frame body two is connected to an installation box, and the installation box is equipped with a worm gear transmission and a rotating member connected to the worm gear transmission, the worm gear transmission can be self-locking, and the worm gear transmission is also connected to the transmission rod one, and the worm gear transmission can drive the transmission rod one to rotate.

[0016] By adopting the above technical solution, the driving member can drive the transmission rod 1 to rotate through the worm gear transmission member. The rotation of the transmission rod 1 will drive the two supporting legs to rotate away or closer through the transmission of the transmission rod 2 and the transmission rod 3, thereby changing the distance between the two cutting blades. The present application can adjust the distance between the two cutting blades in real time to facilitate cutting of different sizes of inch pads.

[0018] By adopting the above technical solution, the pressing of the second ring plate on the cutting blade can be released by rotating the locking member, and the cutting blade can be rotated to adjust the angle of the cutting blade.

[0019] Preferably, the cutting blade comprises a blade body connected to a connecting shaft, the bottom end of the blade body comprises a blade portion, and the blade portion comprises an anti-stick coating on a wall surface.

[0020] By adopting the above technical solution, the anti-stick coating can prevent the glue from sticking to the blade as much as possible.

[0021] Preferably, the poking material assembly comprises a fixing frame arranged on a frame, the fixing frame is provided with a lifting member, the lifting member is provided with a fixing plate, and the fixing plate is provided with a poking column.

[0022] By adopting the above technical solution, since the spiral cutting method is used to cut the product strip in this application, after the cutting blade is retracted after the cutting is completed, the inch pad will usually stick to the product strip due to viscosity. For this, it is necessary to drive the lifting part to drive the poking column to poke the inch pad off.

[0023] Preferably, a collecting cylinder with an upward opening is provided on the frame below the poking column, and the collecting cylinder is detachably connected to the frame.

[0024] By adopting the above technical solution, the collecting cylinder can easily collect the fallen inch pads.

[0025] Preferably, the material preparation and unwinding mechanism includes a first unwinding assembly for unwinding a viscous adhesive material with a first protective film and a second protective film affixed thereto, a second unwinding assembly for unwinding a release film material, a third unwinding assembly for unwinding a inch pad material, a first winding assembly for winding up the first protective film, and a second winding assembly for winding up the second protective film, and the first unwinding assembly, the second unwinding assembly, the third unwinding assembly, the first winding assembly, and the second winding assembly are all arranged on a frame; the frame is also provided with a guide roller group and a pressing assembly, the guide roller group is used for guiding the first protective film and the second protective film on the separated viscous adhesive material and for guiding the release film material, the viscous adhesive material and the inch pad tape material to overlap, and the pressing assembly is used for pressing the release film material, the viscous adhesive material and the inch pad tape material into a product tape.

[0026] By adopting the above technical scheme, based on the flexible combination of the first unwinding assembly, the second unwinding assembly, the third unwinding assembly, the first winding assembly and the second winding assembly and under the guidance of the guide roller group, the first protective film and the second protective film on the viscous adhesive material will be separated and the release film material and the inch pad tape will be superimposed on both sides respectively, and then the release film material, the viscous adhesive material and the inch pad tape can be pressed into the product tape by using the pressing assembly, which is highly efficient.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects: 1. Since the inch pad is annular, in this application, the cutting blade needs to cut the product strip twice, specifically, first cutting with a small circle trajectory and then cutting with a large circle trajectory on the product strip. In this application, the driving drive component three can drive the two cutting blades to move away from or close to each other, thereby adjusting the size of the circle drawn by the cutting blades to meet the needs of two cuttings; in this regard, taking the specific action of one of the cutting as an example: the driving drive component two drives the two legs to rotate and move at the same time, thereby driving the two cutting blades to rotate and draw a circle and then cut the product strip. Since the movement trajectory of the cutting blade is a spiral line, the pressure on the viscous adhesive material in the product strip is relatively small when the cutting blade cuts the viscous adhesive material, which is equivalent to the cutting blade making a continuous circular shallow cut on the viscous adhesive material, and the adhesive is not easily squeezed out and adheres to the cutting blade. This application can be applied to cutting inch pads of different sizes and thicknesses. Specifically, different cutting methods can be used for inch pads of different thicknesses and sizes to prevent the adhesive from adhering to the cutting tool. For thinner product strips, the cutting blade angle can be changed to change the cutting blade angle when it cuts into the product strip to reduce the deformation and extrusion of the sticky pad during the cutting process, which can also reduce the pressure on the sticky material when it is cut. In addition, since the product strip is thin, it is usually only necessary to drive the second drive component to drive the two cutting blades to rotate a total of one circle, that is, each rotating half a circle to complete the cutting, which ensures processing efficiency. For thicker product strips, the above-mentioned spiral track cutting method is usually used; 2. By driving the rotating member, the worm gear transmission member can drive the transmission rod 1 to rotate. The rotation of the transmission rod 1 will drive the two legs to rotate away or closer through the transmission of the transmission rods 2 and 3, thereby changing the distance between the two cutting blades. The present application can adjust the distance between the two cutting blades in real time to facilitate cutting of different sizes of inch pads. In addition, the rotation of the locking member can release the pressure of the second ring plate on the cutting blade, and the cutting blade can be rotated to adjust the angle of the cutting blade; 3. Since the present application adopts a spiral cutting method to cut the product strip, after the cutting blade is retracted after cutting, the inch pad will usually stick to the product strip due to stickiness. For this reason, it is necessary to drive the lifting member to drive the poking column to poke the inch pad off, and the collecting cylinder can facilitate the collection of the fallen inch pad.

[0032] The embodiment of the present application discloses a inch-pad cutting device, which is used to cut out annular inch-pads and minimize the occurrence of glue being squeezed out and causing the cutting blade to adhere to the glue. The present application can be applied to cutting inch-pads of different thicknesses and sizes.

[0033] Reference Figure 2 A inch-mat cutting device includes a frame 1, on which a material preparing and unwinding mechanism 2, a cutting mechanism 3 and a rewinding mechanism 4 are installed from left to right. The material preparing and unwinding mechanism 2 can prepare product strips and unwind them, the cutting mechanism 3 can cut inch-mats from the product strips, and the rewinding mechanism 4 can rewind the remaining product strips after cutting.

[0034] The material making and unwinding mechanism 2 produces the product strip and is reeled up by the reeling mechanism 4. The product strip moves to the right and passes through one side of the cutting mechanism 3 to be cut into a sized pad by the cutting mechanism 3.

[0035] Reference Figure 3 The material preparation and unwinding mechanism 2 includes a first unwinding component 21 for unwinding a viscous adhesive material b with a first protective film b1 and a second protective film b2, a second unwinding component 22 for unwinding a release film a, a third unwinding component 23 for unwinding a pad material, a first rewinding component 24 for rolling up the first protective film b1, and a second rewinding component 25 for rolling up the second protective film b2. The first unwinding component 21, the second unwinding component 22, the third unwinding component 23, the first rewinding component 24, and the second rewinding component 25 are all arranged on the frame 1; the frame 1 is also provided with a guide roller group 26 and a pressing component 27, the guide roller group 26 is used to guide the first protective film b1 and the second protective film b2 on the separated viscous adhesive material b, and guide the release film a, the viscous adhesive material b and the pad tape c to overlap, and the pressing component 27 is used to press the release film a, the viscous adhesive material b and the pad tape c into a product tape.

[0036] Reference Figure 3 and Figure 4The first unwinding assembly 21, the second unwinding assembly 22, the third unwinding assembly 23, the first winding assembly 24 and the second winding assembly 25 have the same structure. Take the structure of the first unwinding assembly 21 as an example: the first unwinding assembly 21 includes a connecting frame 211 arranged on the frame 1, and a roller body 212 and a driving member 213 connected to the roller body 212 are rotatably connected to the connecting frame 211. The driving member 213 is preferably a motor. The guide roller group 26 includes a guide roller 1 261, a guide roller 2 262, a guide roller 3 263 and a guide roller 4 264 rotatably connected to the frame 1. The second unwinding assembly 22, the first winding assembly 24, the guide roller 2 262, the guide roller 1 261, the first unwinding assembly 21, the guide roller 3 263, the second winding assembly 25, the guide roller 4 264 and the third unwinding assembly 23 are arranged in sequence from left to right. The pressing assembly 27 includes a frame plate 271 disposed on the frame 1, and two upper and lower heat pressing rollers 272 are rotatably connected to the frame plate 271, and a heat pressing motor is connected to each heat pressing roller 272 on the frame plate 271. Of course, in order to ensure the stable movement of the product, a plurality of pairs of guide roller groups 28 are rotatably provided on the frame 1, and the product will pass between the guide roller groups 28.

[0037] First, the first unwinding assembly 21 unwinds the viscous adhesive material b with the first protective film b1 and the second protective film b2, and the guide roller 1 261 guides the viscous adhesive material b with the first protective film b1 and the second protective film b2 to the guide roller 2 262. At this time, the first winding assembly 24 separates the first protective film b1 from the viscous adhesive material b, and then the viscous adhesive material b with the second protective film b2 is guided by the guide roller 2 262 to the guide roller 3 263. In this process, the second unwinding assembly 22 unwinds the release film a so that the release film a reaches under and contacts the sticky adhesive material b with the second protective film b2, and the second protective film b2 is rolled up and separated by the second winding assembly 25 at the guide roller three 263 position. When the sticky adhesive material b with the release film a reaches the guide roller four 264 position, the second winding assembly 25 unwinds the inch padding tape to overlap on the upper end of the sticky adhesive material b, and then the overlapped release film a, sticky adhesive material b and inch padding tape c arrive between the two hot pressing rollers 272 and are pressed together.

[0038] Reference Figure 5 and Figure 6The cutting mechanism 3 includes a driving assembly 1 31 connected to the frame 1, the driving assembly 1 31 is connected to a frame 1 32, the frame 1 32 is equipped with a driving assembly 2 33, the driving assembly 2 33 is connected to a frame 2 34, the frame 2 34 is equipped with two oppositely arranged legs 35, each leg 35 is provided with a cutting blade 36 at the bottom, and the cutting blade 36 is configured to be able to rotate and fix so as to change the angle at which the cutting blade 36 cuts into the product strip. The driving assembly 2 33 can drive the two cutting blades 36 to rotate and move at the same time, wherein the motion trajectory of each cutting blade 36 is a spiral line. The frame 2 34 is also equipped with a driving assembly 3 37, the driving assembly 3 37 is connected to the two legs 35, each leg 35 is rotatably connected to the frame 2 34, and the driving assembly 3 37 can drive the two legs 35 to rotate in opposite directions so as to make the two cutting blades 36 move away from or close to each other.

[0039] Since the inch pad is annular, in the present application, the cutting blade 36 needs to cut the product strip twice, specifically, first cutting with a small circle track and then cutting with a large circle track on the product strip, and in order to improve the cutting efficiency, refer to Figure 2 In this embodiment, two cutting mechanisms 3 are provided. The left cutting mechanism 3 is used to cut the product strip with a small circle trajectory, that is, to cut out the inner hole of the annular inch pad. The right cutting mechanism 3 is used to cut the product strip with a large circle trajectory, that is, to cut out the outer circle of the inch pad.

[0040] Taking the specific action of one of the cutting mechanisms 3 cutting out a inch pad as an example: driving component 1 31 drives the two cutting blades 36 to move above the product strip, driving component 2 33 drives the two legs 35 to rotate and move downward at the same time, thereby driving the two cutting blades 36 to rotate in a circle and move downward at the same time to cut the product strip.

[0041] Since the movement trajectory of the cutting blade 36 is a spiral line, the pressure on the viscous adhesive material b in the product strip is relatively small when the cutting blade 36 cuts the viscous adhesive material b, which is equivalent to the cutting blade 36 making continuous circular shallow cuts on the viscous adhesive material b, and the adhesive is not easily squeezed out and adheres to the cutting blade 36.

[0042] The present application can be applied to cutting out inch pads of different sizes and thicknesses. Specifically, different cutting methods can be used for inch pads of different thicknesses and sizes to prevent the glue from adhering to the cutting tool. For product strips with smaller thicknesses, the angle of the cutting blade 36 can be changed to change the angle at which the cutting blade 36 cuts into the product strip to reduce the deformation and extrusion of the sticky rubber pad during the cutting process. This can also reduce the pressure on the sticky rubber material b when it is cut. Moreover, since the product strip is relatively thin, it is usually only necessary to drive the second driving component 33 to drive the two cutting blades 36 to rotate a total of one circle, that is, each of them rotates half a circle to complete the cutting, which ensures processing efficiency. For product strips with larger thicknesses, the above-mentioned spiral trajectory cutting method is usually used.

[0044] The vertical reciprocating cylinder 312 is driven to move the two cutting blades 36 to above the product strip to prepare for cutting.

[0045] Reference Figure 6 and Figure 7 The driving assembly 2 33 includes a housing 1 331 connected to the frame 1 32. The housing 1 331 is rotatably connected to a gear 1 332 through a bearing. The gear 1 332 is provided with a connecting hole 3321. The connecting hole 3321 is threadedly connected to a coaxial linkage column 1 333. The linkage column 1 333 is also slidably connected to the frame 1 32. The rotation of the gear 1 332 can drive the linkage column 1 333 to move up and down. In order to drive the gear 1 332 to rotate, the frame 1 32 is also equipped with a driving member 334. The driving member 334 is a motor. The driving member 334 is connected to a gear 2 335. The gear 2 335 is externally meshed with the gear 1 332. Driving the driving member 334 can drive the gear 2 335 to rotate, thereby driving the gear 1 332 to rotate.

[0046] Reference Figure 6 and Figure 7In order to make the linkage column 1 333 rotate while moving, the linkage column 1 333 is rotatably connected to the linkage column 2 336 through a bearing, and the linkage column 1 333 and the linkage column 2 336 can move up and down synchronously, and the linkage column 2 336 is connected to the frame 2 34. The frame 1 32 is connected to the housing 2 337, and the housing 2 337 is rotatably connected to the gear 3 338 through a bearing. The gear 3 338 is located above the gear 1 332, and the gear 3 338 is externally meshed with the gear 2 335. The gear 3 338 is fixedly connected to a transmission column 339 that can rotate with it. The linkage column 1 333 is provided with a receiving hole 3331, and the end of the linkage column 2 336 near the linkage column 1 333 is provided with a transmission groove 3361 that is connected to the receiving hole 3331, and the transmission column 339 is penetrated through the receiving hole 3331. The transmission column 339 has a hexagonal transmission part 3391 at one end close to the linkage column 336. The transmission part 3391 is inserted into the transmission groove 3361. The transmission part 3391 and the transmission groove 3361 cooperate to make the transmission part 3391 and the linkage column 336 rotate synchronously.

[0047] The present application can realize the simultaneous movement and rotation of the linkage column 2 336, that is, the two cutting blades 36 move in a spiral trajectory, and the specific implementation action is: the driving driving member 334 drives the gear 2 335 to rotate, thereby driving the gear 1 332 and the gear 3 338 to rotate at the same time, wherein the rotation of the gear 1 332 will drive the linkage column 1 333 to move downward, thereby driving the linkage column 2 336 to move, and the rotation of the gear 3 338 will drive the transmission column 339 to rotate, thereby driving the linkage column 2 336 to rotate through the cooperation of the transmission part 3391 and the transmission groove 3361, and the cutting feed amount of the cutting blade 36 is stable.

[0049] In the present application, the action of adjusting the distance between the two cutting blades 36 is: driving the rotating member 376 to drive the transmission rod 1 371 to rotate through the worm gear transmission member 375, thereby driving the two legs 35 to move away or closer through the transmission rod 1 371, the transmission rod 2 372 and the transmission rod 3 373, thereby changing the distance between the two cutting blades 36. The present application can facilitate cutting of different sizes of inch pads.

The locking piece 53 is configured to be able to rotate and then press against the second ring plate 51 so that the first and second ring plates 51 clamp the cutting blade 36. Of course, the locking piece 53 can also be rotated to drive the second ring plate 51 to move outward to release the clamping of the cutting blade 36. At this time, the cutting blade 36 can be adjusted in angle.

[0052] Reference Fig.10Since the present application adopts a spiral cutting method to cut the product strip, after the cutting blade 36 is retracted after cutting, the inch pad may adhere to the product strip due to viscosity. Therefore, in order to ensure that the inch pad can be separated from the product strip, a poking assembly 11 is also installed on the frame 1, and the poking assembly 11 is used to poke the inch pad away from the product strip.

[0053] Reference Fig.10 The poking assembly 11 includes a fixed frame 111 disposed on the frame 1. The fixed frame 111 is equipped with a lifting member 112. The lifting member 112 is preferably a cylinder. The lifting member 112 is equipped with a fixed plate 113. A plurality of poking posts 114 are installed at the bottom of the fixed plate 113. The lifting member 112 is driven to drive the fixed plate 113 to move up and down, so that the inch pads adhered to the product strip are poked off by the plurality of poking posts 114. In order to facilitate the collection of the inch pads, a collection cylinder 12 with an upward opening is further provided on the frame 1 below the poking posts 114.

[0055] The implementation principle of a inch pad cutting device in the embodiment of the present application is: First, the first unwinding assembly 21 unwinds the viscous adhesive material b with the first protective film b1 and the second protective film b2, and the guide roller 1 261 guides the viscous adhesive material b with the first protective film b1 and the second protective film b2 to the guide roller 2 262. At this time, the first winding assembly 24 separates the first protective film b1 from the viscous adhesive material b, and then the viscous adhesive material b with the second protective film b2 is guided by the guide roller 2 262 to the guide roller 3 263. In this process, the second unwinding assembly 22 unwinds the release film a so that the release film a reaches below and contacts the sticky adhesive material b with the second protective film b2, and the second protective film b2 is rolled up and separated by the second winding assembly 25 at the position of the guide roller three 263. When the sticky adhesive material b with the release film a reaches the position of the guide roller four 264, the second winding assembly 25 unwinds the padding tape to overlap the upper end of the sticky adhesive material b, and then the overlapped release film a, sticky adhesive material b and padding tape c arrive between the two hot pressing rollers 272 and are pressed together; The vertical reciprocating cylinder 312 is driven to drive the two cutting blades 36 to move to the top of the product strip to prepare for cutting; The driving driving member 334 drives the gear 2 335 to rotate, thereby driving the gear 1 332 and the gear 3 338 to rotate at the same time, wherein the rotation of the gear 1 332 will drive the linkage column 1 333 to move downward, thereby driving the linkage column 2 336 to move, and the rotation of the gear 3 338 will drive the transmission column 339 to rotate, thereby driving the linkage column 2 336 to rotate through the cooperation of the transmission part 3391 and the transmission groove 3361, and the two cutting blades 36 cut on the product strip in a circular trajectory. After two rounds of cutting to cut out the inch pad, when the inch pad reaches the bottom of the poking material assembly 11, the driving lifting member 112 drives the fixed plate 113 to move up and down, thereby using multiple poking columns 114 to poke off the inch pad adhered to the product strip, and the inch pad falls into the collecting tube 12 and is collected; thereafter, the cut product strip is wound up by the winding mechanism 4.
