Anti-wrinkle processing equipment for PE (polyethylene) antibacterial preservative film production

Abstract

The invention relates to anti-wrinkle processing equipment for PE (polyethylene) antibacterial preservative film production. The anti-wrinkle processing equipment for PE antibacterial preservative film production comprises a base, a supporting device, a winding device, a working table and a flattening device. According to the anti-wrinkle processing equipment for PE antibacterial preservative film production provided by the invention, through the winding device, a driving motor is started, and the output end of the driving motor drives a winding shaft to rotate, so that a preservative film is conveyed and wound at the same time; through the arranged flattening device, a flattening motor is started, the output end of the flattening motor drives a flattening shaft to rotate, and the flattening shaft rotates to drive a cam to rotate; when a reciprocating plate moves up and down, push rods on the two sides move relatively, so that vertical rollers on the two sides are driven to transversely remove wrinkles when the preservative film is wound; and when the reciprocating plate moves upwards, the reciprocating plate is pushed to ascend due to the acting force of a jacking spring, and the two vertical rollers are quickly close to each other through supporting rods on the two sides when the reciprocating plate ascends, so that the situation that when transverse wrinkle removal is conducted on the preservative film from the middle to the two sides, wrinkle removal and winding of the preservative film are affected is avoided.

Description

technical field [0001] The invention relates to the technical field of plastic wrap, in particular to anti-wrinkle processing equipment for producing PE antibacterial plastic wrap. Background technique [0002] PE is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, and is chemically stable. Good performance, resistant to most acid and alkali erosion, insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation; [0003] Cling film is a kind of plastic packaging product, which is usually made by polymerization reaction with ethylene as the masterbatch. Cling film can be divided into three categories: microwave food heating, refrigerator food preservation, fresh and cooked food packaging and other occasions. It is widely used in supermarkets, h...

AI Technical Summary

Problems solved by technology

[0005] (1) Due to the long length of the preservative film during processing, the existing device cannot unwind and rewind the preservative film during transportation, resulting in a large footprint of the preservative film;

[0006] (2) When the plastic wrap is rolled, the surface of the plastic wrap will wrinkle, and the existing device cannot horizontally and vertically smooth the plastic wrap stretched forward, thereby affecting the winding effect of the plastic wrap;

[0007] (3) During the wrinkle removal and winding when the plastic wrap is transported, the existing device cannot adjust the tightness of the plastic wrap when it is rolled, thus causing inconvenience to the plastic wrap
