[0027] Example: Refer to Figures 1-6 A double-blade edge-cutting machine for PE protective film includes a base 1, and further includes: a mounting frame 2 fixedly mounted on the base 1, the mounting frame 2 having a clamping part for holding the PE protective film; a first mounting plate 3 slidably mounted on the mounting frame 2, the first mounting plate 3 having two sets arranged symmetrically, each set of the first mounting plate 3 having a guide rail 4 fixedly mounted, and each set of guide rails 4 having a mounting seat 5 slidably mounted; a cutting machine 6 having two sets, respectively fixedly mounted on the two sets of mounting seats 5; an adjustment part mounted on the mounting frame 2 and connected to the first mounting plate 3; and a drive part mounted on the mounting frame 2 and connected to the mounting seat 5.

[0028] In this embodiment, by driving two sets of cutting machines 6 to simultaneously cut the two ends of the PE protective film, there is no need to reverse the PE protective film, thereby reducing labor costs and improving the efficiency of cutting the protective film.

[0029] Reference Figure 2 and Figure 3 The adjustment unit includes a second mounting plate 7 fixedly mounted on the mounting bracket 2. A left and right rotating screw 8 is rotatably mounted on the second mounting plate 7. The two ends of the left and right rotating screw 8 are respectively threaded to two sets of first mounting plates 3. A first motor 9 is fixedly mounted on the second mounting plate 7. The output end of the first motor 9 is fixedly connected to the left and right rotating screw 8.

[0030] In this embodiment, the first motor 9 is started, and the first motor 9 drives the left and right rotating screws 8 to rotate. The left and right rotating screws 8 drive the two sets of first mounting plates 3 to slide simultaneously. When sliding, the two sets of first mounting plates 3 slide towards both ends of the mounting frame 2 or move towards the middle of the mounting frame 2 simultaneously, thereby controlling the distance between the two sets of cutting machines 6, which facilitates the cutting of PE protective films of different widths.

[0031] Reference Figures 1-3The drive unit includes a third mounting plate 10 fixedly mounted on the mounting bracket 2. A first lead screw 12 is rotatably mounted on the third mounting plate 10. A push-pull rod 13 is threadedly connected to the first lead screw 12. The two ends of the push-pull rod 13 are slidably connected to two sets of mounting seats 5 respectively. A second motor 11 is fixedly mounted on the third mounting plate 10. The output end of the second motor 11 is fixedly connected to the first lead screw 12. A first handwheel 14 is fixedly mounted on the end of the first lead screw 12 away from the second motor 11.

[0032] Turn the first handwheel 14 or start the second motor 11 to drive the first lead screw 12 to rotate. The first lead screw 12 drives the push-pull rod 13 to move. The push-pull rod 13 drags the two sets of mounting seats 5 to move simultaneously, thereby driving the two sets of cutting machines 6 to move towards the PE protective film at the same time or simultaneously cut the PE protective film, so that the two sets of cutting machines 6 cut synchronously, thereby improving the cutting accuracy.

[0033] Reference Figures 1-3 The clamping part includes a mounting box 15 fixedly mounted on the mounting frame 2 and a slide block 19 slidably mounted on the mounting frame 2. A fourth mounting plate 17 is fixedly mounted on the slide block 19. The fourth mounting plate 17 and the mounting box 15 are respectively located at both ends of the mounting frame 2. A third motor 16 is fixedly mounted inside the mounting box 15. The output end of the third motor 16 extends to the outside of the mounting box 15 and a second insertion rod 34 is fixedly mounted thereon. A first insertion rod 18 is rotatably connected to the fourth mounting plate 17. The end of the PE protective film is inserted into the first insertion rod 18 and the second insertion rod 34. A second lead screw 20 is rotatably connected to the mounting frame 2. The second lead screw 20 is threadedly connected to the slide block 19. A second handwheel 21 is fixedly mounted at the end of the second lead screw 20.

[0034] In use, first turn the second handwheel 21 to drive the fourth mounting plate 17 to slide towards the second handwheel 21. Then, insert one end of the PE protective film into the second insert rod 34. Then, turn the second handwheel 21 again to drive the fourth mounting plate 17 to move away from the second handwheel 21, so that the first insert rod 18 is inserted into the PE protective film to fix the PE protective film. Then, start the third motor 16 to drive the second insert rod 34 to rotate, thereby driving the PE protective film to rotate, thus completing the full cutting.

[0035] Reference Figures 3-6The clamping part includes a fifth mounting plate 22 fixedly mounted on the first mounting plate 3. A mounting ring 23 is rotatably mounted on the fifth mounting plate 22, and the end of the PE protective film is inserted into the mounting ring 23. A hollow seat 31 is fixedly mounted on the fifth mounting plate 22, and a fourth motor 32 is fixedly mounted on the hollow seat 31. A spur gear 33 is fixedly mounted on the output shaft of the fourth motor 32. A spur gear ring 24 is fixedly mounted on the mounting ring 23, and the spur gear ring 24 meshes with the spur gear 33. A rotatable connecting rod is mounted on the mounting ring 23. A bevel gear 27 is connected to the mounting ring 23. A mounting rod 25 is slidably mounted on the mounting ring 23. A rubber pad 26 is fixedly mounted on one end of the mounting rod 25 extending to the inner side of the mounting ring 23. The mounting ring 23 also includes a third lead screw 28, which is threadedly connected to the bevel gear 27. One end of the third lead screw 28 extending to the inner side of the mounting ring 23 is fixedly connected to the rubber pad 26. A bevel ring 29 is rotatably connected to the mounting ring 23. The bevel ring 29 meshes with the bevel gear 27. A handle 30 is fixedly mounted on the outer side of the bevel ring 29.

[0036] In use, by starting the first motor 9, the distance between the two sets of first mounting plates 3 is increased, and then the PE protective film is rotated through the holes of the two sets of mounting rings 23. Then, the first motor 9 is started again to decrease the distance between the two sets of first mounting plates 3, so that the PE protective film is inserted into the inner holes of the two sets of mounting rings 23. Then, the handle 30 drives the bevel gear ring 29 to rotate, and the bevel gear ring 29 drives multiple sets of bevel gears 27 to rotate synchronously. There are 4-12 sets of bevel gears 27. In this embodiment, there are six sets. The multiple bevel gears 27 are circumferentially distributed on the mounting rings 23. When the bevel gears 27 rotate, the rubber pad 26 moves simultaneously to the center of the mounting ring 23 under the action of the mounting rod 25 and the third lead screw 28, thereby clamping the PE protective film. Then, the fourth motor 32 is started, and the fourth motor 32 drives the spur gear 33 to rotate. The spur gear 33 drives the spur gear ring 24 to rotate, thereby driving the mounting ring 23 to rotate. This drives the PE protective film to rotate and cooperate with the cutting machine 6 to complete the cutting.

[0037] In summary, this device, through two symmetrically arranged cutting machines 6, can simultaneously trim both ends of the PE protective film, avoiding the cumbersome operation of reversing direction required by traditional single-blade cutting, thereby significantly improving trimming efficiency and reducing labor costs.

[0038] By cooperating with the left and right rotating lead screw 8 and the first motor 9, the distance between the two sets of cutting machines 6 can be easily adjusted to accommodate PE protective films of different widths.

[0039] The drive unit in this device ensures that the two sets of cutting machines 6 can move synchronously and stably, thereby guaranteeing the accuracy and consistency of the cutting.

[0040] Both clamping designs effectively secure the PE protective film, preventing it from moving or shifting during cutting. The second clamping design, in particular, achieves tight clamping of the PE protective film through the cooperation of the bevel gear 27, mounting rod 25, and rubber pad 26. It is also easy to operate and adjust. Furthermore, it prevents the PE protective film from shaking due to the centrifugal force of rotation during cutting, further improving the cutting accuracy.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
