Method and mechanism for rewinding preservative film

Abstract

The invention discloses a method for rewinding a preservative film. The method comprises the following steps of: unwinding and conveying a film, putting the film into a winding device, and simultaneously putting a paper tube into a paper tube conveyer through a paper tube discharging component; when the paper tube reaches a side edge of the winding device, winding the film on the paper tube under the rotation of a winding roller; placing the paper tube close to a preservative film cutting device, cutting the film by the preservative film cutting device, continuously winding one part of the film on the paper tube, and winding the other part of the film to a new paper tube of an upper track process step by blowing to automatically finish unwinding, conveying, winding, cutting process steps of the film so as to obtain a preservative film paper tube finished product. The invention also discloses a mechanism for rewinding the preservative film, wherein the paper tube conveyer is arranged at the side edge of the winding device on a frame, a paper tube bin and the paper tube discharging component are arranged above the paper tube conveyer on the frame, and the preservative film cutting device is arranged on the lower side part of the paper tube conveyer on the frame. By the method and the device, the working efficiency is high, the labor cost is low, and the rewinding quality of the preservative film paper tube is obviously improved.

Description

technical field [0001] The invention relates to a film rewinding method and a mechanism thereof, in particular to a film rewinding method and a rewinding mechanism for rewinding a large paper tube film onto a small paper tube. Background technique [0002] The film rewinding mechanism is a device that rewinds the large paper tube film onto the small paper tube through the processes of unwinding, conveying, winding and slitting. The small-sized plastic film and paper tubes made by it are widely used in food, medicine and other fields according to different materials and characteristics, and are suitable for various high-grade film packaging, plastic bag film, protective film and so on. At present, the rewinding of the plastic wrap is processed by unwinding, conveying, and rewinding, and then it needs to be manually cut to make a plastic wrap paper tube; With continuous conveying function. This method has low work efficiency, high input labor cost, and affects the cutting qu...

AI Technical Summary

Problems solved by technology

At present, the rewinding of plastic wrap is processed by unwinding, conveying, and winding, and then it needs to be cut manually to make plastic wrap paper tubes; and the paper tubes used for plastic wrap are individually conveyed, not with continuous delivery

This method has low working efficiency and high labor cost, and the cutting quality of the plastic wrap is affected due to manual operation.
