Description

Technical Field

[0001] This utility model relates to the field of film winding technology, and in particular to an anti-wrinkle winding device for polyethylene film used in food packaging. Background Technology

[0002] Polyethylene film for food packaging is a type of film made primarily from polyethylene (PE) and used for packaging food. It functions to regulate the oxygen and moisture content around the food being preserved, and can block dust from the air, thereby extending the shelf life of food and preventing food contamination and waste.

[0003] During the winding process, if the tension is too high or uneven, the film edge will shorten and curl, forming excess film, which will eventually cause the film to wrinkle during winding. At the same time, the required rolling pressure is different for polyethylene films of different thicknesses and materials. In order to eliminate wrinkles as much as possible, we propose an anti-wrinkle winding device for polyethylene film for food packaging. Utility Model Content

A first electric telescopic mechanism is provided on the top of the fixed plate, and a crushing roller is provided at the end of the first electric telescopic mechanism. A connecting rod is vertically arranged on the first connecting rod, and a first limiting roller is fixedly arranged through the connecting rod.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the embodiments

[0019] Please see Figures 1-3 A wrinkle-resistant winding device for polyethylene film used in food packaging includes a base 1, two vertical rods 2 mounted on the base 1, and a horizontal rod 8 installed between the two vertical rods 2. A first connecting rod 23 and a second connecting rod 26 are fixedly arranged between the vertical rods 2. The first connecting rod 23 is positioned above the second connecting rod 26. A mounting base 22 is provided on the second connecting rod 26. A first rotating rod 5 is mounted on the mounting base 22. A collecting roller 6 is provided at the end of the first rotating rod 5. A first drive motor 3 is provided on one side of the vertical rod 2. The output shaft of the first drive motor 3 and the first rotating rod are also included. A first transmission belt 4 is tensioned between 5. Two second rotating rods 11 are fixedly installed on the crossbar 8. Each second rotating rod 11 is equipped with a fixed roller 12. An installation plate 15 is set between the two fixed rollers 12 on the crossbar 8. Fixed plates 17 are symmetrically arranged on the installation plate 15. A first electric telescopic mechanism 18 is set on the top of the fixed plate 17. A rolling roller 19 is set at the end of the first electric telescopic mechanism 18. A connecting rod is vertically set on the first connecting rod 23, and a first limiting roller 13 is fixedly set through the connecting rod. A second limiting roller 14 is slidably set on the first connecting rod 23.

[0020] The first limiting roller 13 and the second limiting roller 14 are arranged vertically and vertically respectively. A second electric telescopic mechanism 24 is provided on one side of the first connecting rod 23. A sliding plate 25 is fixedly installed at the end of the second electric telescopic mechanism 24. The sliding plate 25 is fixedly connected to the second limiting roller 14.

[0021] A number of L-shaped rods 20 are symmetrically arranged on the mounting plate 15. Each L-shaped rod 20 is provided with a limit block 21, and a gap is left between the bottom of the limit block 21 and the mounting plate 15.

[0022] A diagonal bar 9 is also provided on one side of the crossbar 8, and several transmission rods 10 are provided on the diagonal bar 9.

[0023] The fixed plate 17 has symmetrical through slots in the middle. The two ends of the rolling roller 19 extend to the outside of the fixed plate 17 through the through slots.
