Abstract

The invention discloses a transverse stretching mechanism for a polyimide film. The transverse stretching mechanism for the polyimide film comprises an imidization device, a stretching device and a preheating device. The imidization device and the preheating device are fixedly connected to the left side and the right side of the stretching device correspondingly. The imidization device, the stretching device and the preheating device are internally and correspondingly provided with two first film winding devices, two second film winding devices and two third film winding devices correspondingly. An infrared heating device is perpendicularly arranged at the bottom of the inner wall of the imidization device. The bottom of the inner wall of the stretching device is fixedly connected with a hot air heating device. The front side and the back side of the stretching device are both fixedly connected with heat preservation boards. The transverse stretching mechanism for the polyimide film has the advantages that two polyimide films are conveyed in the stretching device, during conveyance, heat on the front side and the back side of the stretching device can communicate with each other, so that heat loss can be reduced, and heat can be well utilized; and compared with original equipment, the stretching efficiency is improved by one time, and the stretching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a transverse stretching mechanism for polyimide films, in particular to a transverse stretching mechanism for polyimide films. Background technique [0002] The transverse stretching machine is a stand-alone machine in the polyimide film production line. Its main function is to stretch the film transversely according to a certain stretching ratio, and make the film reach a certain specification after imidization treatment. [0003] Existing transverse stretching machines have certain defects. One is that the utilization rate of internal heat is low; to the requirement, and the stretching is inefficient. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides a transverse stretching mechanism for polyimide film, which solves the problems of low heat utilization rate, uneven heating and direct heat treatment of...
