A film take-up roll device

Abstract

A film wind-up roll device comprises a guide roll rotating anticlockwise, a first wind-up roll rotating clockwise, a second wind-up roll which rotates clockwise and is parallel to the first wind-up roll, a cutter device and a support, wherein a converting roll which is capable of rotating in two directions and parallel to the first wind-up roll is arranged in the support, a rotary shaft is arranged in the middle of the converting roll, and the two ends of the rotary shaft are supported by the support; the first wind-up roll and the second wind-up roll are located in the converting roll, the two ends of the first wind-up roll are erected in the converting roll through first support shafts respectively and can be taken down, the two ends of the second wind-up roll are erected in the converting roll through second support shafts respectively and can be taken down, the cutter device comprises a lifting cylinder arranged in the support, a cutter is connected to the output end of the lifting cylinder, and the converting roll is provided with a hollowed-out portion allowing the cutter to penetrate therein. By the adoption of the device, full-process automation of rolling up and reel alternation of films is achieved, the success rate of rolling up is effectively increased, product loss is reduced, and product cost is reduced.

Description

technical field [0001] The invention relates to a film winding roller device. Background technique [0002] At present, most of the biaxially stretched film production lines use double-station automatic winding machines, which maintain continuous production without stopping during winding. The knife cuts the winding film, cuts the film with one hand, and attaches the film to the surface of the empty winding roller with the other hand, gradually let the film attach to the winding roller, then runs the winding roller to the normal working position, and then removes the winding roller. Finished rolling rollers, complete winding and changing rolls. Such a winding and changing method consumes manpower, and there is a risk of manual film cutting and changing operations. At the same time, the success rate of such a winding and changing method is unstable, which is likely to cause film waste and defective products. Contents of the invention [0003] In order to overcome the abov...

AI Technical Summary

Problems solved by technology

This kind of winding and changing method is labor-intensive, and there is a danger of manual film cutting and changing operations. At the same time, the success rate of this kind of winding and changing method is unstable, which is easy to cause waste of film and defective products.
