Technical Field
[0001] This utility model relates to the field of protective film cutting technology, specifically to a high-efficiency cutting machine for PE protective film production. Background Technology
[0002] PE protective film is a protective film product made of special polyethylene plastic film as the base material. PE material is the simplest high-molecular organic compound in terms of structure and is also one of the most widely used polymer materials in the world today. It has advantages such as high transparency, good air release performance, strong adhesion, not easy to delaminate, high temperature resistance, wear resistance, scratch resistance, and good flexibility, and is widely used in various industries.
[0003] In the production of PE protective film, the finished PE protective film needs to be cut into a certain length and then wound onto a roll to obtain a roll of PE protective film. However, in existing equipment, it is difficult to complete the winding and cutting processes at the same time. Often, the PE protective film needs to be cut at equal intervals before winding and packaging, which is very troublesome and inefficient. Utility Model Content

The roll is sleeved and fixed on the rotating roller, which is arranged in the front-back direction. The rear end of the rotating shaft is rotatably mounted on the mounting rod and connected to the drive shaft of the film winding motor. The clamping roller is arranged parallel to the rotating roller, and the rear end of the rotating shaft is rotatably mounted on the slider. The slider is slidably mounted in the groove, and after the lower end of the slider and the groove are connected by a spring, the clamping roller and the rotating roller abut together.
[0012] As an improvement, the positioning structure includes a positioning frame and a positioning roller; the positioning frame is arranged with its opening facing to the left, and the bracket is connected and fixed on the rear frame rod of the positioning frame; the positioning roller is arranged parallel to the rotating roller, and the rotating shaft is rotatably set on the positioning frame; after the PE protective film passes through the bottom of the positioning roller, it overlaps on the roll of the adjacent film roll structure and is wound on the roll of another film roll structure.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.
[0026] A high-efficiency cutting machine for PE protective film production, such as Figure 1 , 2 As shown, it includes:
[0027] Positioning structures, such as Figure 1 As shown, it includes a positioning frame 2 and a positioning roller 4; the positioning frame 2 is arranged with its opening facing to the left and a base is provided at the bottom; the positioning roller 4 is arranged with its opening facing forward and backward, and its rotating shaft is rotatably set inside the opening of the positioning frame 2; the bracket 3 is an L-shaped plate structure, and one end of its horizontal section is connected and fixed to the rear frame rod of the positioning frame 2, and the process switching structure is set at the other end of the horizontal section.
[0028] Process switching structure such as Figure 5As shown, it includes a switching motor 9 and a turntable 5; the switching motor 9 is fixed on the rear side of the bracket 3, the turntable 5 is arranged on the front side of the bracket 3, and three mounting rods 10 are evenly formed along the circumferential opening on the side wall, and the rotating shaft is rotatably set on the bracket 3 and connected to the drive shaft of the switching motor 9. A sliding groove 11 is formed on the front side wall of the mounting rod 10.
[0029] Rolled film structure such as Figure 5 As shown, three components are arranged circumferentially on the process switching structure and correspondingly mounted on each mounting rod 10. The structure includes a rotating roller 6, a clamping roller 7, a slider 12, a spring 13, and a film winding motor 8. The film winding motor 8 is fixed on the rear side wall of the mounting rod 10. The rotating roller 6 is arranged in the front-back direction, and its rear end shaft is rotatably mounted on the mounting rod 10 and connected to the drive shaft of the film winding motor 8. The clamping roller 7 is arranged parallel to the rotating roller 6, and its rear end shaft is rotatably mounted on the slider 12. The slider 12 is slidably mounted in the groove 11 formed on the front side wall of the mounting rod 10. After the end of the slider 12 is connected to the groove 11 by the spring 13, the clamping roller 7 and the rotating roller 6 abut against each other.
[0030] PE protective film 18 and roll 17; the roll 17 is sleeved and fixed on each rotating roller 6, and after the PE protective film 18 is produced, it passes through the bottom of the positioning roller 4 and overlaps the roll 17 of the adjacent film structure, and finally winds onto the roll 17 of another film structure (e.g., Figure 1 As shown, another roll-up structure is the roll-up structure located on the outermost side.
[0031] Cutting structure, such as Figure 4 , 5 As shown, it includes a U-shaped knife holder 14, a cylinder telescopic rod 15, and a knife seat 16. The U-shaped knife holder 14 is fixed at the bottom of the vertical section of the support 3 (directly above the process switching structure), and its opening is set between the clamping roller 7 and the rotating roller 6 of the adjacent film winding structure. The front end of the knife seat 16 is fixed with a knife head 1, which is slidably set inside the U-shaped knife holder 14.

[0033] With manual assistance, the worker passes the PE protective film 18 through the bottom of the positioning roller 4, overlaps it on the roll 17 of the adjacent film winding structure, and winds it onto the roll 17 of the outermost film winding structure. The corresponding clamping roller 7 clamps the PE protective film 18 between the clamping roller 7 and the roll 17. The film winding motor 8 of the outermost film winding structure is turned on, and its rotating roller 6 drives the corresponding roll 17 to rotate, winding the PE protective film 18 onto the roll 17. When the length of the PE protective film 18 on the roll 17 is sufficient, the film winding motor 8 stops, and the film winding motor 8 of the adjacent film winding structure is turned on. The cylinder extension rod 15 extends, and the cutter head 1 inserts into the clamping roller 7 and the rotating roller 6. Meanwhile, the PE protective film 18 is cut and the cut end of the PE protective film 18 abuts against the roll 17 of the adjacent film winding structure. Under its rotation, it is wound onto the roll 17. At the same time, the cylinder extension rod 15 extends and retracts, the knife holder 16 retracts into the U-shaped knife holder 14, and the switching motor 9 starts. After the turntable 5 rotates 120°, the original adjacent film winding structure and its roll 17 are moved to the outermost position, and the original bottom film winding structure and its roll 17 are moved to the adjacent position and abut against the PE protective film 18. The original outer film winding structure is moved to the bottom, and the worker removes the PE protective film 18 roll 17 after winding and replaces it with a new roll 17.
