Detailed Embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0026] A PE heat shrinkable film trimming device is provided with a cleaning plate 9 at the top, and a trimming head 12 is arranged inside the lifting frame 2. It also includes:

[0027] A moving processing component, which is located inside the operating table 1 and is used to drive the cleaning plate 9 to move so as to process waste materials;

[0028] A trimming component, which is located on the outer surface of the lifting frame 2 and is used to drive the trimming head 12 to perform horizontal and vertical trimming. The trimming head 12 can flexibly perform precise trimming operations on the PE heat shrinkable film to remove unnecessary edges or irregular parts.

[0029] Furthermore, the moving processing component includes a rectangular groove 6, a first motor 7, a second threaded rod 10 and a second moving block 20. Two symmetrically distributed rectangular grooves 6 are opened at the top of the operating table 1. Second moving blocks 20 are slidably connected inside the two rectangular grooves 6. A second threaded rod 10 is rotatably connected inside one of the rectangular grooves 6. The outer surface of the operating table 1 is fixedly installed with a first motor 7. The output end of the first motor 7 is fixedly connected to the end of the second threaded rod 10. The second threaded rod 10 is threadedly sleeved with the corresponding second moving block 20. The tops of the two second moving blocks 20 are fixedly connected to the bottom of the cleaning plate 9. The first motor 7 drives the second threaded rod 10 to rotate in the rectangular groove 6. Since the second threaded rod 10 is threadedly sleeved with the second moving block 20, as the second threaded rod 10 rotates, the two second moving blocks 20 will move towards the middle or both sides along the rectangular groove 6. The movement of the second moving block 20 drives the cleaning plate 9 to move above the operating table 1.

[0030] Furthermore, a notch 5 is opened at the top of the operating table 1. The waste materials are pushed to the notch 5 by the movement of the cleaning plate 9 to realize automatic cleaning of the waste materials.

[0031] Furthermore, sliding grooves 19 are opened on the inner walls of the two corresponding sides of the fixed block 3. Sliders 11 are slidably connected inside the two sliding grooves 19. The outer surfaces of the two sliders 11 close to each other are fixedly connected to the outer surface of the lifting frame 2. A pushing cylinder 4 is fixedly installed at the top of the fixed block 3. The output end of the pushing cylinder 4 is fixedly connected to the top of the lifting frame 2. The height of the lifting frame 2 is adjusted by the pushing cylinder 4. The output end of the pushing cylinder 4 is fixedly connected to the top of the lifting frame 2. The up and down movement of the lifting frame 2 is controlled by the telescoping of the cylinder. The sliding grooves 19 and the sliders 11 on both sides of the fixed block 3 ensure the stable movement of the lifting frame 2 in the vertical direction, so that the lifting frame 2 covers the PE heat shrinkable film.

[0032] Furthermore, the trimming component includes a first threaded rod 8, a first moving block 15, a second guiding column 16, and a third motor 18. Two adapter blocks are fixedly connected to the top of the lifting frame 2. A first threaded rod 8 is rotatably connected between the two adapter blocks. A third motor 18 is fixedly installed on the top of one of the adapter blocks, and the output end of the third motor 18 is fixedly connected to the end of the first threaded rod 8. A second guiding column 16 is fixedly connected between the two adapter blocks. The outer surface of the first threaded rod 8 is threadedly sleeved with a first moving block 15, and the second guiding column 16 is movably sleeved with the other first moving block 15. The third motor 18 drives the first threaded rod 8 to rotate between the two adapter blocks. Since the first threaded rod 8 is threadedly sleeved with the first moving block 15 and the first moving block 15 is also guided by the second guiding column 16, the two first moving blocks 15 will move along the axial direction of the first threaded rod 8 on the outer surface of the lifting frame 2, realizing the lateral trimming of the trimming head 12.

[0033] Furthermore, a third threaded rod 13 is rotatably connected between the two first moving blocks 15. A first guiding column 14 is fixedly connected between the two first moving blocks 15. A second motor 17 is fixedly installed on the outer surface of one of the first moving blocks 15, and the output end of the second motor 17 is fixedly connected to the end of the third threaded rod 13. The trimming head 12 is threadedly sleeved with the third threaded rod 13 and movably sleeved with the first guiding column 14. The second motor 17 drives the third threaded rod 13 to rotate between the two first moving blocks 15. Since the trimming head 12 is threadedly sleeved with the third threaded rod 13 and guided by the first guiding column 14, the trimming head 12 will move along the axial direction of the third threaded rod 13, realizing the longitudinal trimming.

[0034] Furthermore, the two first moving blocks 15 are slidably connected to the outer surface of the lifting frame 2, and the two first moving blocks 15 will move along the axial direction of the first threaded rod 8 on the outer surface of the lifting frame 2.

[0035] Working principle: When the staff needs to use this PE heat shrinkable film trimming device, the roll of PE heat shrinkable film is placed on one side of the operating table 1, and then the PE heat shrinkable film is pulled and placed on the operating table 1. The height of the lifting frame 2 is adjusted by pushing the cylinder 4. The output end of the pushing cylinder 4 is fixedly connected to the top of the lifting frame 2. The up and down movement of the lifting frame 2 is controlled by the telescopic movement of the cylinder. The sliding grooves 19 and the sliding blocks 11 on both sides of the fixed block 3 ensure the stable movement of the lifting frame 2 in the vertical direction. When the lifting frame 2 covers the PE heat shrinkable film, the third motor 18 is started. The third motor 18 drives the first threaded rod 8 to rotate between the two adapter blocks. Since the first threaded rod 8 is threadedly sleeved with the first moving block 15, and the first moving block 15 is also guided by the second guiding column 16, the two first moving blocks 15 will move along the axial direction of the first threaded rod 8 on the outer surface of the lifting frame 2, realizing the horizontal trimming of the trimming head 12. When longitudinal trimming is required, the second motor 17 is started. The second motor 17 drives the third threaded rod 13 to rotate between the two first moving blocks 15. Since the trimming head 12 is threadedly sleeved with the third threaded rod 13 and is guided by the first guiding column 14, the trimming head 12 will move along the axial direction of the third threaded rod 13, realizing longitudinal trimming. By combining the horizontal and longitudinal trimming actions, the trimming head 12 can flexibly perform precise trimming operations on the PE heat shrinkable film, removing the unnecessary edges or irregular parts. After trimming, when it is necessary to clean the waste, the first motor 7 is started. The first motor 7 drives the second threaded rod 10 to rotate in the rectangular groove 6. Since the second threaded rod 10 is threadedly sleeved with the second moving block 20, as the second threaded rod 10 rotates, the two second moving blocks 20 will move towards the middle or both sides along the rectangular groove 6. The movement of the second moving block 20 drives the cleaning plate 9 to move above the operating table 1. The waste is pushed to the notch 5 through the movement of the cleaning plate 9, realizing the automatic cleaning of the waste.
