Description

Technical Field

[0001] This application relates to the technical field of inch pad cutting, and particularly relates to an inch pad cutting device. Background Art

[0002] An inch pad is a commonly used component, which is widely used in multiple fields such as mechanical manufacturing, electronic equipment, and the automotive industry. Among them, in mechanical manufacturing, inch pads are generally used for sealing and buffering of equipment parts. In electronic equipment, inch pads usually play the role of insulation and shock absorption. In the automotive industry, inch pads are mainly arranged at key parts of engines and transmissions.

[0003] Typically, in the production and manufacturing of new energy vehicle batteries in the automotive industry, inch pads are generally used to be attached and installed at one end of the battery. The inch pad is usually annular, and this kind of inch pad is mainly used to protect the battery and prevent the battery from short - circuiting or leaking. It is also conducive to heat dissipation and can protect the battery shell from wear.

[0004] Generally, referring to Figure 1 , the inch pad is composed of a release film, an adhesive film, and an inch pad sheet which are arranged in sequence. Generally, before production, it is necessary to prepare continuous release film material a, adhesive material b, and inch pad strip material c in advance. Due to storage and transportation problems, the two sides of the adhesive material b are usually respectively pasted with a first protective film b1 and a second protective film b2. 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 material a, the adhesive material b, and the inch pad strip material c in sequence to form a product strip. Then, a cutting device is used to cut out inch pads on the product strip. Based on the different installation requirements of different batteries, the inch pads need to have different sizes and different thicknesses.

[0005] The existing cutting device includes a supporting table for laying flat the product strip. Above the supporting table, there is a driving member and a cutting blade. By driving the driving member, the cutting blade is driven to move downward quickly to quickly cut out inch pads on the product strip.

[0006] The cutting blade for cutting may adhere to the glue of the adhesive film. When cutting, since the cutting blade is too perpendicular to the product strip, the pressure of the cutting blade on the adhesive film is relatively large, which may cause a large extrusion of a part of the adhesive film, and the glue may be extruded out and adhered to the side wall of the cutting blade. When too much glue adheres, the cutting may get stuck, the cutting accuracy will also decrease, and the cutting efficiency will be affected. Summary of the Invention

[0007] In order to minimize the situation where the cutting blade adheres to the glue as much as possible, this application provides an inch pad cutting device.

[0008] The inch pad cutting device provided by this application adopts the following technical solutions:

[0009] A pad cutting device includes a frame. The frame is equipped with a material making and unwinding mechanism, a cutting mechanism, and a winding mechanism. The material making and unwinding mechanism is configured to be able to make a product strip and unwind it. The cutting mechanism is configured to be able to cut pads on the product strip. The winding mechanism is configured to be able to wind the product strip.

[0010] The cutting mechanism includes a first driving component connected to the frame. The first driving component is connected to a first frame body. The first frame body is equipped with a second driving component. The second driving component is connected to a second frame body. The second frame body is equipped with two oppositely arranged supporting feet. Each of the supporting feet is provided with a cutting blade. 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 second driving component is configured to be able to drive the two cutting blades to rotate and move simultaneously. Among them, the movement trajectory of each cutting blade is a spiral. A third driving component is also installed on the second frame body. The third driving component is connected to the two supporting feet. Each supporting foot is rotatably connected to the second frame body. The third driving component is configured to be able to drive the two supporting feet to rotate in opposite directions so that the two cutting blades move away from or close to each other. A material punching component is also installed on the frame. The material punching component is used to punch the pads away from the product strip.

[0011] By adopting the above technical solution, the following actions can be achieved: The material making and unwinding mechanism makes the product strip and the winding mechanism winds it. The product strip will pass by one side of the cutting mechanism and be cut into pads by the cutting mechanism.

[0012] Since the pads are annular, in this application, the cutting of the product strip by the cutting blade needs to be carried out twice. Specifically, first cut along a small circle trajectory and then along a large circle trajectory on the product strip. In this application, driving the third driving component can drive the two cutting blades to move away from or close to each other so as to adjust the size of the circle drawn by the cutting blade to meet the requirements of the two cuts.

[0013] Regarding this, taking the specific action of one of the cuts as an example: Driving the second driving component drives the two supporting feet to rotate and move simultaneously, thereby driving the two cutting blades to rotate and draw a circle, and then cutting the product strip.

[0014] Since the movement trajectory of the cutting blade is a spiral, when the cutting blade cuts the viscous adhesive material in the product strip, the pressure on the viscous adhesive material is relatively small. It is equivalent to the cutting blade performing continuous circular shallow cuts on the viscous adhesive material, and the glue is not easily extruded and adhered to the cutting blade.

[0015] This application is applicable to cutting mats of different sizes and thicknesses. Specifically, for mats with different thicknesses and sizes, different cutting methods can be adopted to prevent glue from adhering to the cutting tool. For the product strip with a smaller thickness, the angle of the cutting edge can be changed to change the angle when the cutting edge cuts into the product strip, so as 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 during cutting. Moreover, since the thickness of the product strip is small, usually only need to drive the second driving component to drive the two cutting edges to rotate one week together, that is, each rotates half a week to complete the cutting, which ensures the processing efficiency. For the product strip with a larger thickness, the above-mentioned spiral trajectory cutting method is usually adopted.

[0016] Preferably, the second driving component includes a first housing connected to the first frame. A first gear is rotatably connected to the first housing. The first gear is provided with a connection hole, and a first linkage column is threadedly connected to the connection hole. The first linkage column is also slidably connected to the first frame. The rotation of the first gear can drive the first linkage column to move.

[0017] The first frame is further provided with a driving member, and the driving member is connected to a second gear. The second gear is in transmission connection with the first gear.

[0018] The first linkage column is rotatably connected to a second linkage column, and the first linkage column and the second linkage column can move synchronously. The second linkage column is connected to the second frame.

[0019] The first frame is connected to a second housing. A third gear is rotatably connected to the second housing. The third gear is in transmission connection with the second gear. The third gear is connected to a transmission column that can rotate together. The first linkage column is provided with a receiving hole, and the second linkage column is provided with a transmission groove communicating with the receiving hole. The transmission column passes through the receiving hole. One end of the transmission column close to the second linkage column has a transmission portion, and the transmission portion is inserted into the transmission groove. The transmission portion and the second linkage column can rotate synchronously. When the second linkage column moves relative to the transmission column, the transmission portion can always drive the transmission groove to rotate so as to drive the second linkage column to rotate.

[0020] By adopting the above technical solution, driving the driving member can drive the second gear to rotate, thereby driving the first gear and the third gear to rotate simultaneously. Among them, the rotation of the first gear will drive the first linkage column to move, thereby driving the second linkage column to move. And the rotation of the third gear will drive the transmission column to rotate, thereby driving the second linkage column to rotate through the transmission portion. The above realizes the relatively stable rotation and movement of the second linkage column, and the cutting feed amount of the cutting edge is stable.

[0021] Preferably, the third driving assembly includes a first transmission rod. One end of the first transmission rod is hinged to the second frame body, and the other end is hinged to a second transmission rod. The end of the second transmission rod away from the first transmission rod is hinged to one of its feet. A third transmission rod is hinged at the middle position of the first transmission rod. The end of the third transmission rod away from the first transmission rod is hinged to the other foot. The second frame body is connected with an installation box, and a worm and worm gear transmission member and a rotating member connected to the worm and worm gear transmission member are installed in the installation box. The worm and worm gear transmission member can be self-locked, and the worm and worm gear transmission member is also connected to the first transmission rod. The worm and worm gear transmission member can drive the first transmission rod to rotate.

[0022] By adopting the above technical solution, driving the rotating member can drive the first transmission rod to rotate through the worm and worm gear transmission member. The rotation of the first transmission rod will drive the two feet to rotate away from or close to each other through the transmission of the second transmission rod and the third transmission rod, 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 pads of different sizes.

[0023] Preferably, a first ring plate and a second ring plate are provided at the end of the foot. Both the first ring plate and the second ring plate have the ability to deform. A connecting shaft is fixedly connected to the cutting blade. One end of the connecting shaft is rotatably connected to the ring hole of the first ring plate, and the other end is rotatably connected to the ring hole of the second ring plate. A locking member is threadedly connected to the end of the connecting shaft away from the first ring plate. The locking member is configured to be able to rotate and press against the second ring plate so that the first ring plate and the second ring plate clamp the cutting blade.

[0024] By adopting the above technical solution, rotating the locking member can release the pressing of the second ring plate on the cutting blade. At this time, the cutting blade can be rotated to adjust the angle of the cutting blade.

[0025] Preferably, the cutting blade includes a blade body connected to the connecting shaft. The bottom end of the blade body has a cutting edge, and the cutting edge includes an anti-sticking coating on the wall surface.

[0026] By adopting the above technical solution, the anti-sticking coating can prevent adhesion to the cutting edge as much as possible.

[0027] Preferably, the punching component includes a fixed frame provided on the machine frame. A lifting member is installed on the fixed frame, a fixing plate is installed on the lifting member, and a punching column is installed on the fixing plate.

[0028] By adopting the above technical solution, since the spiral cutting method is adopted in the present application to cut the product strip, after the cutting is completed and the cutting blade retracts, the pad usually adheres to the product strip due to viscosity. For this reason, it is necessary to drive the lifting member to drive the punching column to punch the pad off.

[0029] Preferably, a collection cylinder with an upward opening is further provided on the frame below the punching post, and the collection cylinder is detachably connected to the frame.

[0030] By adopting the above technical solution, the collection cylinder can facilitate the collection of the dropped inch pads.

[0031] Preferably, the material feeding and unwinding mechanism includes a first unwinding assembly for unwinding a sticky adhesive material with a first protective film and a second protective film attached thereto, a second unwinding assembly for unwinding a release film material, a third unwinding assembly for unwinding an inch pad material, a first winding assembly for winding the first protective film, and a second winding assembly for winding the second protective film. 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 the frame. A guiding roller group and a pressing assembly are further arranged on the frame. The guiding roller group is used for guiding the separation of the first protective film and the second protective film on the sticky adhesive material and guiding the superposition of the release film material, the sticky adhesive material, and the inch pad strip. The pressing assembly is used for pressing the release film material, the sticky adhesive material, and the inch pad strip into a formed product strip.

[0032] By adopting the above technical solution, 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 guiding roller group, the first protective film and the second protective film on the sticky adhesive material will be separated and the release film material and the inch pad strip will be respectively superimposed on both sides. Then, the release film material, the sticky adhesive material, and the inch pad strip can be pressed into a formed product strip by using the pressing assembly, and the efficiency is relatively high.

[0033] In summary, the present invention includes at least one of the following beneficial technical effects:

[0034] 1. Since the inch pads are annular, in this application, the cutting blades need to cut the product strip twice. Specifically, first cut along a small circle trajectory and then along a large circle trajectory on the product strip. In this 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 requirements of the two cuts. For this, taking the specific movement of one of the cuts as an example: the driving component two drives the two supporting feet to rotate and move simultaneously, thereby driving the two cutting blades to rotate and draw a circle, and then cutting the product strip. Since the movement trajectory of the cutting blade is a spiral line, when the cutting blade cuts the viscous adhesive material in the product strip, the pressure on the viscous adhesive material is relatively small, which is equivalent to the cutting blade making continuous circular shallow cuts on the viscous adhesive material, and the glue is not easily extruded and adhered to the cutting blade. This application can be applied to cut inch pads of different sizes and thicknesses. Specifically, for inch pads with different thicknesses and sizes, different cutting methods can be used to avoid the glue adhering to the cutting tool. For a product strip with a smaller thickness, the angle of the cutting blade can be changed to change the angle at which the cutting blade cuts into the product strip, so as to reduce the deformation and extrusion of the viscous adhesive pad during the cutting process. This can also reduce the pressure on the viscous adhesive material during cutting. And because the product strip has a smaller thickness, usually only need to drive the driving component two to drive the two cutting blades to rotate one full circle, that is, each rotates half a circle to complete the cutting, which ensures the processing efficiency. For a product strip with a larger thickness, the above-mentioned spiral trajectory cutting method is usually adopted;

[0035] 2. By driving the rotating part, the driving worm and worm gear transmission part can drive the first transmission rod to rotate. The rotation of the first transmission rod will drive the two supporting feet to rotate away from or close to each other through the transmission of the second transmission rod and the third transmission rod, thereby changing the distance between the two cutting blades. This application can adjust the distance between the two cutting blades in real time to facilitate cutting inch pads of different sizes. In addition, by rotating the locking part, the pressing of the second ring plate on the cutting blade can be released. At this time, the cutting blade can be rotated to adjust the angle of the cutting blade;

[0036] 3. Since the spiral cutting method is adopted in this application to cut the product strip, after the cutting is completed and the cutting blade retracts, the inch pads usually adhere to the product strip due to viscosity. For this, it is necessary to drive the lifting part to drive the punching column to punch down the inch pads, and the collecting cylinder can facilitate the collection of the dropped inch pads.

[0049] The present invention will be further described in detail below with reference to the accompanying drawings.

[0050] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0051] The embodiment of the present application discloses a cutting device for inch pads, which can cut out annular inch pads and minimize the situation where glue is extruded and adheres to the cutting blade. The present application can be applicable to cutting inch pads with different thicknesses and sizes.

[0052] Refer to Figure 2, A cutting device for inch pads includes a frame 1. From left to right, a material feeding and unwinding mechanism 2, a cutting mechanism 3, and a winding mechanism 4 are successively installed on the frame 1. The material feeding and unwinding mechanism 2 can produce a product strip and unwind it. The cutting mechanism 3 can cut inch pads on the product strip. The winding mechanism 4 can wind the remaining product strip after cutting is completed.

[0053] The material feeding and unwinding mechanism 2 produces the product strip and the winding mechanism 4 winds it. The product strip will move to the right and pass by one side of the cutting mechanism 3, where the cutting mechanism 3 cuts out inch pads.

[0054] Refer to Figure 3 , The material feeding and unwinding mechanism 2 includes a first unwinding assembly 21 for unwinding a sticky adhesive material b with a first protective film b1 and a second protective film b2 attached, a second unwinding assembly 22 for unwinding a release film material a, a third unwinding assembly 23 for unwinding inch pad materials, a first winding assembly 24 for winding the first protective film b1, and a second winding assembly 25 for winding the second protective film b2. The 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 are all arranged on the frame 1. A guiding roller group 26 and a pressing assembly 27 are also arranged on the frame 1. The guiding roller group 26 is used to guide the separation of the first protective film b1 and the second protective film b2 on the sticky adhesive material b and to guide the superposition of the release film material a, the sticky adhesive material b, and the inch pad strip c. The pressing assembly 27 is used to press the release film material a, the sticky adhesive material b, and the inch pad strip c into a product strip.

[0055] Refer to Figure 3 and Figure 4 , The structures of the 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 are the same. Taking 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. A roller body 212 is rotatably connected to the connecting frame 211, and a driving member 213 connected to the roller body 212. The driving member 213 is preferably a motor. The guiding roller group 26 includes a first guide roller 261, a second guide roller 262, a third guide roller 263, and a fourth guide roller 264 rotatably connected to the frame 1. The second unwinding assembly 22, the first winding assembly 24, the second guide roller 262, the first guide roller 261, the first unwinding assembly 21, the third guide roller 263, the second winding assembly 25, the fourth guide roller 264, and the third unwinding assembly 23 are arranged in sequence from left to right. The pressing assembly 27 includes a frame plate 271 arranged on the frame 1. Two upper and lower hot pressing rollers 272 are rotatably connected to the frame plate 271. A hot pressing motor is connected to each hot pressing roller 272 on the frame plate 271. Of course, in order to ensure the stable movement of the product, multiple pairs of guiding roller groups 28 are rotatably arranged on the frame 1, and the product will pass through between the guiding roller groups 28.

[0056] First, the first unwinding assembly 21 unwinds the adhesive material b with the first protective film b1 and the second protective film b2 attached. The adhesive material b with the first protective film b1 and the second protective film b2 attached is guided by the first guide roller 261 to reach the second guide roller 262. At this time, the first winding assembly 24 separates the first protective film b1 from the adhesive material b. Then, the adhesive material b with the second protective film b2 attached reaches the third guide roller 263 under the guidance of the second guide roller 262. During this process, the second unwinding assembly 22 unwinds the release film material a so that the release film material a reaches below and contacts the adhesive material b with the second protective film b2 attached. And at the position of the third guide roller 263, the second protective film b2 is wound and separated by the second winding assembly 25. When the adhesive material b with the release film material a attached reaches the position of the fourth guide roller 264, the second winding assembly 25 unwinds and stacks the inch pad tape on the upper end of the adhesive material b. Then, the stacked release film material a, adhesive material b, and inch pad tape material c reach between the two hot pressing rollers 272 and are pressed together.

[0057] Referring to Figure 5 and Figure 6 As shown in FIGS. 7 and 8, the cutting mechanism 3 includes a first driving assembly 31 connected to the frame 1. The first driving assembly 31 is connected to a first frame 32. The first frame 32 is provided with a second driving assembly 33. The second driving assembly 33 is connected to a second frame 34. The second frame 34 is provided with two oppositely arranged supporting feet 35. At the bottom end of each supporting foot 35, a cutting blade 36 is provided. The cutting blade 36 is configured to be able to rotate and be fixed so as to change the angle at which the cutting blade 36 cuts into the product strip. The second driving assembly 33 can drive the two cutting blades 36 to rotate and move simultaneously. Among them, the movement track of each cutting blade 36 is a spiral line. A third driving assembly 37 is also installed on the second frame 34. The third driving assembly 37 is connected to the two supporting feet 35. Each supporting foot 35 is rotatably connected to the second frame 34. The third driving assembly 37 can drive the two supporting feet 35 to rotate in opposite directions so that the two cutting blades 36 move away from or close to each other.

[0058] Since the inch pad is annular, in this application, the product strip needs to be cut by the cutting blade 36 twice. Specifically, it is first cut in a small circle track and then in a large circle track on the product strip. In order to improve the cutting efficiency, referring to Figure 2 FIGS. 7 and 8, in this embodiment, two cutting mechanisms 3 are provided. The left cutting mechanism 3 is used to cut the product strip in a small circle track, that is, to cut out the inner hole of the annular inch pad, and the right cutting mechanism 3 is used to cut the product strip in a large circle track, that is, to cut out the outer circle of the inch pad.

[0059] Taking the specific action of cutting the inch pads by one of the cutting mechanisms 3 as an example: The driving component one 31 drives the two cutting blades 36 to move above the product strip. The driving component two 33 drives the two support feet 35 to rotate and move downward simultaneously, thereby driving the two cutting blades 36 to rotate in a circle and move downward simultaneously to cut the product strip.

[0060] Since the movement trajectory of the cutting blade 36 is a spiral line, when the cutting blade 36 cuts the viscous adhesive b in the product strip, the pressure on the viscous adhesive b is relatively small. It is equivalent to the cutting blade 36 performing continuous circular shallow cuts on the viscous adhesive b, and the glue is not easily extruded and adhered to the cutting blade 36.

[0061] This application can be applicable to cutting inch pads of different sizes and thicknesses. Specifically, for inch pads with different thicknesses and sizes, different cutting methods can be adopted to avoid the glue adhering to the cutting tool. For product strips with a smaller thickness, the angle of the cutting blade 36 can be changed to change the angle when the cutting blade 36 cuts into the product strip to reduce the deformation and extrusion of the viscous glue pad during the cutting process. This can also reduce the pressure on the viscous adhesive b during cutting. And since the thickness of the product strip is smaller, usually only the driving component two 33 needs to drive the two cutting blades 36 to rotate one full circle (i.e., each rotates half a circle) to complete the cutting, which ensures the processing efficiency. For product strips with a larger thickness, the above-mentioned method of cutting with a spiral trajectory is usually adopted.

[0062] Refer to Figure 5 , the driving component one 31 includes a horizontally reciprocating cylinder 311 installed on the frame 1 and a vertically reciprocating cylinder 312 installed on the horizontally reciprocating cylinder 311. The frame one 32 is installed on the vertically reciprocating cylinder 312.

[0063] Drive the vertically reciprocating cylinder 312 to drive the two cutting blades 36 to move above the product strip to prepare for cutting.

[0064] Refer to Figure 6 and Figure 7 , the driving component two 33 includes a housing one 331 connected to the frame one 32. The housing one 331 is rotatably connected with a gear one 332 through a bearing. The gear one 332 is provided with a connection hole 3321, and a coaxial linkage column one 333 is threadedly connected to the connection hole 3321. The linkage column one 333 is also slidably connected to the frame one 32. The rotation of the gear one 332 can drive the linkage column one 333 to move up and down. In order to be able to drive the gear one 332 to rotate, the frame one 32 is also provided with a driving and rotating part 334. The driving and rotating part 334 is a motor. The driving and rotating part 334 is connected with a gear two 335, and the gear two 335 is externally engaged with the gear one 332. Driving the driving and rotating part 334 can drive the gear two 335 to rotate and thus drive the gear one 332 to rotate.

[0065] Reference Figure 6 and Figure 7 In order to enable the first linkage column 333 to rotate while moving, the first linkage column 333 is rotatably connected to the second linkage column 336 through a bearing, and the first linkage column 333 and the second linkage column 336 can move up and down synchronously. The second linkage column 336 is connected to the second frame 34. The first frame 32 is connected to a second housing 337. The second housing 337 is rotatably connected to a third gear 338 through a bearing. The third gear 338 is located above the first gear 332. The third gear 338 is externally engaged with the second gear 335. The third gear 338 is fixedly connected to a transmission column 339 that can rotate together. The first linkage column 333 is provided with a receiving hole 3331. The end of the second linkage column 336 close to the first linkage column 333 is provided with a transmission groove 3361 communicating with the receiving hole 3331. The transmission column 339 is inserted into the receiving hole 3331. One end of the transmission column 339 close to the second linkage column 336 has a hexagonal transmission portion 3391. The transmission portion 3391 is inserted into the transmission groove 3361. Through the cooperation of the transmission portion 3391 and the transmission groove 3361, the transmission portion 3391 can rotate synchronously with the second linkage column 336. In this application, when the second linkage column 336 moves relative to the transmission column 339, the transmission portion 3391 can always drive the second linkage column 336 to rotate, and the transmission portion 3391 will not be completely separated from the transmission groove 3361.

[0066] This application can realize the simultaneous movement and rotation of the second linkage column 336, that is, the two cutting blades 36 move along a spiral trajectory. The specific implementation action is as follows: driving the driving and rotating member 334 to drive the second gear 335 to rotate, thereby driving the first gear 332 and the third gear 338 to rotate simultaneously. Among them, the rotation of the first gear 332 will drive the first linkage column 333 to move downward, thereby driving the second linkage column 336 to move, and the rotation of the third gear 338 will drive the transmission column 339 to rotate, thereby driving the second linkage column 336 to rotate through the cooperation of the transmission portion 3391 and the transmission groove 3361, and the cutting feed amount of the cutting blade 36 is stable.

[0067] Reference Figure 6 and Figure 8, the driving component three 37 includes a first transmission rod 371. One end of the first transmission rod 371 is hinged to the second frame 34, and the other end is hinged with a second transmission rod 372, and the hinge point is located at the end of the second transmission rod 372. The end of the second transmission rod 372 away from the first transmission rod 371 is hinged to one of its support feet 35, and the hinge point is located at the 1 / 3 position of the support foot 35 from bottom to top; the first transmission rod 371 is hinged with a third transmission rod 373, and the hinge point is located at the 2 / 5 position of the first transmission rod 371 from right to left. The end of the third transmission rod 373 away from the first transmission rod 371 is hinged to the other support foot 35, and the hinge point is located at the 1 / 5 position from top to bottom; the second frame 34 is connected with an installation box 374. The installation box 374 is installed with a worm and worm gear transmission part 375 and a rotating part 376 connected to the worm and worm gear transmission part 375. The rotating part 376 is a motor. The worm and worm gear transmission part 375 can be self-locked. The worm and worm gear transmission part 375 is connected with the first transmission rod 371, and the worm and worm gear transmission part 375 can drive the first transmission rod 371 to rotate.

[0068] In this application, the action of adjusting the distance between the two cutting blades 36 is as follows: driving the rotating part 376 to drive the first transmission rod 371 to rotate through the worm and worm gear transmission part 375, so as to drive the two support feet 35 to move away from or close to each other through the first transmission rod 371, the second transmission rod 372 and the third transmission rod 373, and then change the distance between the two cutting blades 36. This application can facilitate the cutting of cushion pads of different sizes.

[0069] Refer to Figure 9 , in order to facilitate the adjustment of the orientation of the cutting blade 36, that is, the angle at which the cutting blade 36 cuts into the product strip, parallel first ring plate 5 and second ring plate 51 are provided at the bottom end of the support foot 35. Both the first ring plate 5 and the second ring plate 51 have the ability to deform. A connecting shaft 52 is fixedly connected to the cutting blade 36. One end of the connecting shaft 52 is rotatably connected to the ring hole of the first ring plate 5, and the other end is rotatably connected to the ring hole of the second ring plate 51. The axial direction of the connecting shaft 52 is perpendicular to the walking direction of the product strip. A locking part 53 is threadedly connected to the end of the connecting shaft 52 away from the first ring plate 5. The locking part 53 is a nut. The locking part 53 is configured to be able to rotate and then press against the second ring plate 51 so that the first ring plate 5 and the second ring plate 51 clamp the cutting blade 36. Of course, the locking part 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 angle of the cutting blade 36 can be adjusted.

[0070] Refer to Figure 9 , the cutting blade 36 includes a blade body 361 connected to the connecting shaft 52. The bottom end of the blade body 361 has a cutting edge 362. The cutting edge 362 includes an anti-adhesive coating on the wall surface. The anti-adhesive coating is an isolating agent such as zinc stearate.

[0071] Refer to Figure 10, since the spiral cutting method is adopted in this application to cut the product strip, after the cutting blade 36 retracts after the cutting is completed, 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 punching component 11 is also installed on the frame 1, and the punching component 11 is used to punch the inch pad off the product strip.

[0072] Refer to Figure 10 , the punching component 11 includes a fixed frame 111 provided on the frame 1. The fixed frame 111 is installed with a lifting member 112. The lifting member 112 is preferably a cylinder. The lifting member 112 is installed with a fixing plate 113, and the bottom end of the fixing plate 113 is installed with a plurality of punching columns 114. By driving the lifting member 112 to drive the fixing plate 113 to move up and down, the inch pad adhered to the product strip is punched off by the plurality of punching columns 114. In order to facilitate the collection of the inch pad, a collection cylinder 12 with an upward opening is also provided on the frame 1 below the punching columns 114. Combined with Figure 1 , a collecting box 13 is provided on the left side of the collecting cylinder 12 below the two cutting mechanisms 3. The collecting box 13 is used to collect the inch pads that may fall after the cutting mechanism 3 finishes cutting, and the collecting cylinder 12 is used to collect the inch pads punched off by the punching columns 114. The collecting cylinder 12 is detachably connected to the frame 1. Specifically, in this application, a limiting ring 14 is provided on the frame 1, and the collecting cylinder 12 is placed in the limiting ring 14.

[0073] Refer to Figure 10 , the winding mechanism 4 includes a winding roller 41 rotatably connected to the frame 1, and the winding roller 41 is connected to a motor.

[0074] The implementation principle of an inch pad cutting device in an embodiment of this application is as follows:

[0075] First, the first unwinding component 21 unwinds the adhesive material b with the first protective film b1 and the second protective film b2 attached. The adhesive material b with the first protective film b1 and the second protective film b2 attached reaches the guide roller two 262 under the guidance of the guide roller one 261. At this time, the first winding component 24 separates the first protective film b1 from the adhesive material b, and then the adhesive material b with the second protective film b2 attached reaches the guide roller three 263 under the guidance of the guide roller two 262. During this process, the second unwinding component 22 unwinds the release film material a so that the release film material a reaches below the adhesive material b with the second protective film b2 attached and contacts it. And at the position of the guide roller three 263, the second protective film b2 is wound and separated by the second winding component 25. When the adhesive material b with the release film material a attached reaches the position of the guide roller four 264, the second winding component 25 unwinds the inch pad strip and stacks it on the upper end of the adhesive material b. Then, the stacked release film material a, adhesive material b, and inch pad strip c reach between the two hot pressing rollers 272 and are pressed together;

[0076] Drive the vertical reciprocating cylinder 312 to drive the two cutting blades 36 to move above the product strip to prepare for cutting;

[0077] The driving and rotating member 334 drives the second gear 335 to rotate, thereby driving the first gear 332 and the third gear 338 to rotate simultaneously. Among them, the rotation of the first gear 332 drives the first linkage column 333 to move downward, thereby driving the second linkage column 336 to move. The rotation of the third gear 338 drives the transmission column 339 to rotate, and through the cooperation of the transmission part 3391 and the transmission groove 3361, drives the second linkage column 336 to rotate. The two cutting blades 36 cut on the product strip in a circular trajectory. After two rounds of cutting to cut out the inch pads, when the inch pads reach below the punching component 11, the driving lifting member 112 drives the fixing plate 113 to move up and down, thereby using a plurality of punching columns 114 to punch the inch pads adhered to the product strip. The inch pads fall into the collection cylinder 12 and are collected; then the cut product strip is wound by the winding mechanism 4.
