Description

Technical Field

[0001] This invention relates to the field of PE film production equipment technology, and in particular to a PE film production edge recycling device. Background Technology

[0002] PE film, or polyethylene film, refers to films produced using PE film. PE film has high air permeability, which decreases with increasing density. Existing PE film production requires size limitations, and there is a lack of convenient and quick waste recycling components after edge trimming.

[0003] Chinese utility model application number CN202320227998.3 discloses a PE film production edge-cutting and recycling device. This device uses a cutter to slit the film and a clamping block that drives the insertion groove to fix the cut film waste edges, causing them to wind around the take-up roller as it rotates. However, this method is susceptible to interference from the cutter when winding the film onto two roll rollers, and requires an additional third servo motor to control the take-up roller's rotation, increasing costs. Furthermore, the method of winding the film waste edges into a single strand and inserting it into the insertion groove requires manual cutting, winding, and insertion, increasing the workload for workers and making it more difficult to reuse the recycled film waste edges, thus reducing the recycling efficiency. Summary of the Invention

[0004] The present invention proposes an edge-cutting and recycling device for PE film production, which aims to solve the problem that the traditional method of winding the waste film edges into a strand and inserting it into the insertion groove for winding requires manual cutting and winding of the waste film edges, which increases the workload of the workers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] Preferably, the threaded rod and the threaded connection parts of the two sliding blocks have the same pitch and opposite helical directions, one end of the threaded rod passes through the sliding groove and is fixedly connected to a handle.

[0014] Preferably, the top of the recycling tank is connected to a slitting groove near the unwinding roller, and the slitting groove cooperates with two slitting blades.

[0015] Preferably, the pressing assembly includes a telescopic plate, a connecting rod, and a pressing structure. A vertical sliding groove is provided on the side of the cutter holder away from the unwinding roller. Two telescopic plates are slidably connected in the vertical sliding groove. A connecting rod is fixedly connected to the output end of each of the two telescopic plates. The two connecting rods are connected to the two sliding frames one-to-one. A pressing structure is connected to the bottom of both ends of the telescopic plates. The output ends of the two pressing structures abut against the sides of the film waste.

[0016] Preferably, the telescopic plate includes a vertical slide plate and a sliding plate. The vertical slide plate is slidably connected in the telescopic groove along the vertical direction. Each of the two vertical slide plates has a telescopic groove on its opposite side. A sliding plate is slidably connected in the telescopic groove. The gap between the sliding plates is located in the telescopic groove, and the end of the sliding plate away from the vertical slide plate is fixedly connected to the connecting rod. The bottom of the opposite side of the vertical slide plate and the sliding plate is connected to the pressing structure.

[0017] Preferably, the pressing structure includes a pressing block, a rotating shaft, a pressing rod, and a torsion spring.

[0019] Preferably, both the vertical slide plate and the sliding plate are fixedly connected to a face cutter at their bottom sides near the take-up roller, and a face cutter groove is provided on the clamping block near the take-up roller, with both face cutters cooperating with the face cutter groove.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This invention, by setting up a cutting mechanism, can perform cutting operations on the film during transport. The position of the two slitting blades can be adjusted by the adjustment component to facilitate different cutting requirements of the film. The up and down position of the slitting blades can be controlled by setting up an electric telescopic rod, which effectively avoids the film being affected by the slitting blades when winding the film on the unwinding roller to the take-up roller, and reduces the operating burden of the operator.

[0022] 2. By setting up a drive mechanism and driven gear, the present invention can simultaneously drive the unwinding roller, the take-up roller and the waste roller to rotate. By briefly starting the drive motor, the unwinding roller and the take-up roller rotate to transport the film, so that the slitting knife cuts the film to a certain length, avoiding damage to the film body during subsequent recycling of the waste film edge. At the same time, it is used to adjust the waste roller so that the clamping groove of the waste roller faces upward, which facilitates the subsequent recycling operation.

[0023] 3. By setting a telescopic plate, when adjusting the horizontal position of the slitting blade, the sliding frame drives the sliding plate to move through the connecting rod, so that the sliding plate extends out of the telescopic groove in the vertical slide plate, thereby ensuring that the vertical slide plate and the sliding plate always correspond to the edge of the cut film waste, which facilitates the subsequent pressing and cutting operation of the film waste edge.

[0024] 4. By setting up a recycling mechanism, when the output ends of the two electric telescopic rods continue to extend briefly, the telescopic plate pushes the film waste edge downward through the two pressing components, so that the film waste edge is clamped between the two clamping blocks. At the same time, the face cutter on the telescopic plate cuts into the knife groove on the clamping block near the winding roller, cutting off the clamped film waste edge near the winding roller, thus completing the cutting and clamping operation of the film waste edge. This facilitates the winding operation of the film waste edge while the waste roller is rotating, eliminating the need for operators to cut and wind up the film waste edge.

[0025] 5. By setting up a pressing component, when the pressing component moves upward, the pressing rod overcomes the elastic force of the torsion spring and rotates under the obstruction of the bottom of the clamping block, and is pulled back from the two clamping blocks, thus avoiding obstruction to the recycling of film waste.

[0026] In summary, the edge-cutting mechanism completes the edge-cutting operation of the conveyed film and simultaneously rewinds the cut-off film waste edges. This eliminates the need for workers to pull and cut the film waste edges, automatically recovering them and greatly reducing the workload of the workers. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Reference Figures 1-3 A PE film production edge recycling device, comprising:

[0036] The workbench 1 has two mounting slots 2 on both sides. One mounting slot 2 is rotatably connected to the unwinding roller 3, and the other mounting slot 2 is rotatably connected to the winding roller 4.

The output end of the drive motor 5 is coaxially and fixedly connected to one of the transmission gears 6. The same transmission toothed belt 7 is sleeved on the two transmission gears 6.

[0038] The edge trimming mechanism includes a cutter holder 9, an adjustment component, an electric telescopic rod 14, and a slitting blade 16. The cutter holder 9 is fixedly connected to the middle of the worktable 1. An adjustment component is connected to the cutter holder 9. Two electric telescopic rods 14 are connected to the output end of the adjustment component. The adjustment component is used to adjust the position of the two electric telescopic rods 14 at the same time. A sliding frame 15 is fixedly connected to the output end of the electric telescopic rod 14. The slitting blade 16 is fixedly connected to the sliding frame 15 on the side near the unwinding roller 3.

[0039] refer to Figure 5 The adjustment assembly includes a threaded rod 10 and a sliding block 13. A sliding groove 12 is provided inside the cutter holder 9. The threaded rod 10 is rotatably connected to the sliding groove 12. Two sliding blocks 13 are threadedly connected to the threaded rod 10. Both sliding blocks 13 are slidably connected to the sliding groove 12. Two electric telescopic rods 14 are installed on the two sliding blocks 13 one-to-one.

[0040] The threaded rod 10 and the two sliding blocks 13 have the same thread pitch and opposite helical direction at their threaded connection parts. One end of the threaded rod 10 passes through the sliding groove 12 and is fixedly connected to a handle 11, which allows the threaded rod 10 to be rotated easily.

[0041] refer to Figure 4 and Figure 6 The recycling mechanism includes a pressing component, a waste roller 27, and a clamping component. The input end of the pressing component is connected to the side of the sliding frame 15 away from the unwinding roller 3. A recycling trough 8 is provided on the worktable 1. The waste roller 27 is rotatably connected in the recycling trough 8. One end of the waste roller 27 passes through the recycling trough 8 and is coaxially fixedly connected to a driven gear 28. The driven gear 28 meshes with the middle of the transmission belt 7. A clamping component is connected to the waste roller 27. The output end of the pressing component is used to drive the edge of the film waste into the output end of the clamping component.

[0042] The top of the recycling trough 8 is connected to a slitting groove 17 near the unwinding roller 3. The slitting groove 17 cooperates with two slitting blades 16. The depth of the slitting groove 17 is greater than the vertical length of the slitting blades 16, so as to avoid obstructing the slitting blades 16 when they are working.

[0043] The pressing assembly includes a telescopic plate 19, a connecting rod 23, and a pressing structure. A vertical sliding groove 18 is provided on the side of the cutter holder 9 away from the unwinding roller 3. Two telescopic plates 19 are slidably connected in the vertical sliding groove 18. The output ends of the two telescopic plates 19 are fixedly connected to the connecting rods 23. The two connecting rods 23 are connected to the two sliding frames 15 one-to-one. The bottom of both ends of the telescopic plates 19 are connected to the pressing structure. The output ends of the two pressing structures abut against the sides of the film waste.

[0044] The telescopic plate 19 includes a vertical slide plate 20 and a sliding plate 22. The vertical slide plate 20 is slidably connected in the telescopic groove 21 in the vertical direction. The two vertical slide plates 20 are provided with telescopic grooves 21 on opposite sides. The sliding plate 22 is slidably connected in the telescopic groove 21. The gap of the sliding plate 22 is located in the telescopic groove 21, and the end of the sliding plate 22 away from the vertical slide plate 20 is fixedly connected to the connecting rod 23. The bottom of the opposite sides of the vertical slide plate 20 and the sliding plate 22 are both connected to the pressing structure.

[0045] The pressing structure includes a pressing block 24, a rotating shaft 25, a pressing rod 26, and a torsion spring. Multiple pressing blocks 24 are fixedly connected to two vertical sliding plates 20 and a sliding plate 22 in a one-to-one correspondence. The bottom of the pressing block 24 is fixedly connected to the rotating shaft 25, and the pressing rod 26 is coaxially rotatably connected to the rotating shaft 25. When the pressing rod 26 rotates to the horizontal plane, it abuts against the bottom of the pressing block 24. A torsion spring is fixedly connected between the pressing rod 26 and the rotating shaft 25. The pressing rod 26 is initially in a horizontal state.

[0046] The diameter of the contact point between the pressure rod 26 and the edge of the film waste is relatively small, thus preventing the edge of the film waste from being directly squeezed and damaged when the pressure rod 26 contacts the clamping assembly.

[0047] The clamping assembly includes a clamping groove 29, a clamping block 31, and a clamping spring 32. The clamping groove 29 is formed on the waste roller 27. Both sides of the clamping groove 29 are connected to the extrusion groove 30. The clamping block 31 is slidably connected in both extrusion grooves 30. The clamping spring 32 is fixedly connected between the clamping block 31 and the inner wall of the extrusion groove 30.

[0048] The top of one of the two clamping blocks 31 is wedge-shaped, which makes it easy for the pressure rod 26 to push the two clamping blocks 31 open along the wedge-shaped surface.

[0049] Both the vertical slide plate 20 and the sliding plate 22 are fixedly connected to the bottom of the side near the take-up roller 4 with face cutters 33. The clamping block 31 near the take-up roller 4 is provided with a face cutter groove 34. Both face cutters 33 cooperate with the face cutter groove 34. The face cutter 33 cuts the film waste near the take-up roller 4, thus avoiding the film from being pulled in the direction of the take-up roller 4 when the waste roller 27 rotates.

[0050] During operation, pull out one end of the PE film on the unwinding roller 3, pass it under the cutter holder 9, and wind it onto the take-up roller 4. At this time, rotate the threaded rod 10 by the handle 11. The rotation of the threaded rod 10 drives the two sliding blocks 13 to move closer or further apart, thereby adjusting the position of the two slitting blades 16 to facilitate different edge cutting requirements of the film.

[0051] After the position adjustment of the slitting blade 16 is completed, the two electric telescopic rods 14 are started. The output end of the electric telescopic rods 14 extends out and drives the sliding frame 15 to move downward. The end of the sliding frame 15 close to the unwinding roller 3 drives the slitting blade 16 to move downward, so that the slitting blade 16 is in working state. The slitting blade 16 contacts the film before the recycling mechanism, cuts the film and falls into the slitting groove 17.

[0052] At this time, the drive motor 5 is briefly started. The output of the drive motor 5 drives a transmission gear 6 to rotate. The transmission gear 6 drives another transmission gear 6 and the driven gear 28 to rotate through the transmission belt 7, so that the slitting blade 16 cuts the film of a certain length, avoiding damage to the film body during subsequent recycling of the film waste edge. At the same time, it is used to adjust the waste roller 27 so that the clamping groove 29 of the waste roller 27 faces upward, which facilitates the subsequent recycling operation.

[0053] When the sliding block 13 moves, it drives the sliding plate 22 to move through the sliding frame 15, so that the sliding plate 22 extends out of the telescopic groove 21 in the vertical slide plate 20, and the vertical slide plate 20 and the sliding plate 22 correspond to the edge of the cut film waste.

[0054] Continue to briefly control the two electric telescopic rods 14 to extend their output ends, and the slitting blade 16 continues to move downward into the slitting groove 17 to maintain the cutting effect on the film. At the same time, the sliding frame 15 continues to drive the vertical slide plate 20 and the sliding plate 22 to move downward. The vertical slide plate 20 and the sliding plate 22 drive the two pressing components to move downward. The pressing rod 26 in the two pressing components abuts against both sides of the cut film waste edge and pushes the film waste edge downward. The pressing rod 26 moves downward to push open the two clamping blocks 31 and extends below the two clamping blocks 31, so that the film waste edge is clamped between the two clamping blocks 31. At the same time, the face cutting blade 33 on the vertical slide plate 20 and the sliding plate 22 cuts into the blade groove 34 on the clamping block 31 near the winding roller 4, cutting off the clamped film waste edge near the winding roller 4.

[0055] Then, the output ends of the two electric telescopic rods 14 retract to the slitting blade 16 to return to the working state. At this time, under the obstruction of the bottom of the clamping block 31, the pressing rod 26 overcomes the elastic force of the torsion spring and rotates, and is pulled out and retracted from the two clamping blocks 31, completing the preparation operation for recycling the film waste edge.

[0056] Finally, the drive motor 5 is activated to drive the unwinding roller 3 and the take-up roller 4 to rotate. Under the operation of the edge trimming mechanism, the edge trimming operation of the film being transported is completed. At the same time, the waste roller 27 is driven to rotate to complete the winding operation of the cut-off film waste edges during transport. There is no need for the staff to pull and cut the film waste edges. The film waste edges are automatically recovered, which greatly reduces the workload of the staff.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
