The two screw rods 8 rotate, and the outer side of the screw rod 8 is threadedly connected to a threaded block 9. The threaded block 9 is slidably connected to the inner wall of the mounting tube 2, further driving the threaded block 9 to slide on the inner wall of the mounting tube 2. A connecting block 10 is fixedly connected to one side of the threaded block 9. The connecting block 10 is slidably connected to the inside of the guide groove 11. The movement of the threaded block 9 drives the connecting block 10 to move inside the guide groove 11, and the guide groove 11 limits it to avoid deviation. A guide shaft 12 is fixedly connected between the two connecting blocks 10 on the corresponding sides, and a clamping roller 13 is rotatably connected to the outer side of the guide shaft 12. The movement of the connecting block 10 drives the guide shaft 12 and the clamping roller 13 to move up and down, thereby achieving the clamping and positioning effect of the printed film roll, ensuring that the end face of the POF printed film roll is effectively protected during the unloading process. By firmly clamping the two ends of the printed film, the end face of the printed film can be prevented from being damaged due to deviation or collision during transportation.

[0028] In this embodiment, a guide roller 14 is rotatably connected between the two mounting cylinders 2 on the corresponding sides. The guide roller 14 is located at the lower end of the clamping roller 13. The clamping roller 13 can be moved to shorten or expand the distance with the guide roller 14, so that printed films of different thicknesses can be clamped, further improving the applicability of the equipment.

[0029] Example 2

[0030] On the basis of Example 1, the preferred embodiment of the POF printed film roll unloading machine with end face protection function provided by the present invention is as follows: Figures 1 to 5 As shown: a fixing plate 15 is fixedly connected to the right side of the upper end of the base plate 1, and the base plate 1 has a fixed supporting effect on the fixing plate 15. A C-shaped frame 16 is fixedly connected to the upper end of the fixing plate 15, and the fixing plate 15 has a fixing effect on the C-shaped frame 16.

[0031] In this embodiment, the inner wall of the C-shaped frame 16 is provided with front and rear opposite sliding grooves 17 , and the upper end of the C-shaped frame 16 is fixedly connected with front and rear opposite adjustment cylinders 18 , and the C-shaped frame 16 has a fixing effect on the adjustment cylinders 18 .

[0032] In this embodiment, a spring 19 is fixedly connected to the bottom end of the inner wall of the adjusting cylinder 18 in order to further improve the stability of the spring 19. The other end of the spring 19 is fixedly connected to the adjusting rod 20. The spring 19 fixes the adjusting rod 20, and the adjusting rod 20 is slidably connected to the inside of the adjusting cylinder 18.

[0033] In this embodiment, the upper end of the adjusting rod 20 is fixedly connected to a fixed block 21, and the adjusting rod 20 has a fixing effect on the fixed block 21. The inner wall of the fixed block 21 is fixedly connected to a connecting shaft 22, and the middle part of the outer side of the connecting shaft 22 is rotatably connected to a guide roller 23. The connecting shaft 22 is slidably connected to the inside of the slide groove 17. The connecting shaft 22 slides inside the slide groove 17, and then drives the adjusting rod 20 to slide inside the adjusting cylinder 18, and then drives the spring 19 to contract, so that the printing film on the guide roller 23 can be adaptively adjusted in tension, thereby preventing the printing film from slipping on the guide roller 23 and reducing the conveying resistance.

[0034] In this embodiment, a fixing frame 24 is fixedly connected to the middle of the upper end of the base plate 1, and a guide roller 25 is rotatably connected to the inner side of the fixing frame 24. The upper right end of the fixing frame 24 is fixedly connected to front and rear supporting plates 26 opposite to each other, and a guide roller 3 27 is rotatably connected between the two supporting plates 26.

[0035] Furthermore, evenly distributed feet 28 are fixedly connected to the bottom end of the base plate 1 .

[0036] The working principle and usage process of the utility model are as follows: first, the printed film is placed on the two guide rollers 14, and the driving motor 4 is started. The driving motor 4 drives the gear 1 5 to rotate. During the rotation process, the gear 1 5 is meshed and transmitted through the internal rack chain 6 to further drive the gear 2 7 to rotate. The rotation of the gear 1 5 and the gear 2 7 drives the two screws 1 8 to rotate, and further drives the threaded block 1 9 to slide on the inner wall of the installation cylinder 2. The movement of the threaded block 1 9 drives the connecting block 10 to move inside the guide groove 11, and the guide groove 11 limits it to avoid it from deflecting. The movement of the connecting block 10 drives the guide shaft 12 and the clamping roller 13 to move up and down, thereby achieving the clamping and positioning effect of the printed film roll, ensuring that the end face of the POF printed film roll is effectively protected during the unloading process. By firmly clamping one end of the printed film, the end face of the printed film can be prevented from being damaged due to deflection or collision during transportation. The movement of the clamping roller 13 can shorten or expand the distance with the guide roller 14, so that printed films of different thicknesses can be clamped, further improving the applicability of the equipment. The protective film is passed from under the guide roller 25 to above the guide roller 3 27, and then passed from under the guide roller 1 23. In the process of the printed film passing through the guide roller 1 23, a tensioning force is generated on the guide roller 1 23, thereby causing the guide roller 1 23 to move. In the process of movement, the guide roller 1 23 drives the connecting shaft 22 to slide inside the slide groove 17, thereby driving the adjusting rod 20 to slide inside the adjusting cylinder 18, thereby driving the spring 19 to contract, so that the tension of the printed film on the guide roller 1 23 can be adaptively adjusted to prevent the printed film from slipping on the guide roller 1 23, and the tensioning force can be automatically adjusted according to the actual size and characteristics of the printed film, to ensure that the printed film roll always maintains appropriate tension during the unloading process, to avoid deformation or damage of the printed film caused by excessive tightness or excessive looseness.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
