Abstract

The invention discloses a stretching length adjusting device of a polyimide film stretching machine, relates to the technical field of polyimide film stretching machines, and aims to solve the problems that the stretching length of an existing polyimide film stretching machine is inconvenient to adjust, more time is occupied, production is influenced, the adjusting precision is poor and product quality is influenced. A second support is installed on one side of the lower end face of a first support, the second support is welded with the first support, a third support is installed on the otherside of the lower end face of the first support, the third support is welded with the first support, an adjusting screw rod is installed between the second support and the third support, the adjustingscrew rod is connected with the second support and the third support through bearings, anti-collision photoelectric switches are installed on two sides of the front end face of the first support, andthe anti-collision photoelectric switches are connected with the first support through screws.

Description

technical field [0001] The invention relates to the technical field of polyimide film stretching machines, in particular to a stretching length adjusting device of a polyimide film stretching machine. Background technique [0002] Polyimide film includes two types: isophenylene polyimide film and biphenyl polyimide film. The former is a product of DuPont in the United States, made from pyromellitic anhydride and diaminodiphenyl ether. The latter is produced by Japan's Ube Industrial Co., Ltd., and is made of biphenyl tetracarboxylic dianhydride and diphenyl ether diamine (R type) or m-phenylenediamine (S type). Its physical properties: thermosetting polyimide has excellent Excellent thermal stability, chemical resistance and mechanical properties, usually orange. The flexural strength of graphite or glass fiber reinforced polyimide can reach 345 MPa, and the flexural modulus can reach 20 GPa. Thermosetting polyimide has very little creep and has high tensile strength. The...
