Film slitting machine with finished film take-up shafts and edge film take-up shafts separate from each other

Abstract

The invention discloses a film slitting machine with finished film take-up shafts and edge film take-up shafts separate from each other. The film slitting machine comprises a take-up contact roller, a plurality of finished film rolls, two edge film rolls, two finished film take-up shafts, and two edge film take-up shafts. The finished film take-up shafts are disposed on two sides of the take-up contact roller and axially parallel to the take-up contact roller. The finished film rolls alternately disposed on the two finished film take-up shafts at intervals. The edge film take-up shafts are disposed around the take-up contact roller and axially parallel to the take-up contact roller. The two edge film rolls are disposed on the edge film take-up shafts and arranged at two ends of the take-up contact roller respectively. The film slitting machine has the function that take-up defects of the edge film roll are prevented from causing quality problem in the finished film rolls.

Description

technical field [0001] The invention relates to a film slitting machine in which a finished film winding shaft is separated from an edge film winding shaft, and belongs to the technical field of film cutting equipment. Background technique [0002] Metallized film cutting equipment commonly used in the prior art, specifically the J70820-I / zF metallized film cutting machine produced by Xi’an Metro Technology Co., Ltd., its working principle is to put the semi-finished film roll on the On the unwinding shaft of the slitting machine, the film is cut into predetermined specifications after running through a series of guide rollers, flattening rollers, knife groove rollers, pressure rollers, winding rollers and other roller groups. The entire process of film from rolling to winding has strict requirements on process and equipment parameters, especially in the winding stage, the winding structure of the film will directly affect the quality of the finished film roll. [0003] The...

AI Technical Summary

Problems solved by technology

[0005] The present invention is aimed at the deficiencies of the prior art, and provides a film slitting machine in which the finished film winding shaft is separated from the edge film winding shaft, so as to overcome the problems of the finished film when the edge film roll breaks and collapses in the prior art. The roll will produce defects such as loose rolls, inner wrinkles, and uneven edges, which will lead to the problem of scrapping
