Fault early-warning device for polyimide film production equipment

Abstract

The invention discloses a fault early-warning device for polyimide film production equipment, and relates to the technical field of polyimide film production equipment. The device comprises a machinebody and a working motor disposed on the machine body. The working motor and the polyimide film production equipment are in transmission through a gear, and the exterior of the working motor is provided with a standby motor which is parallel to the working motor. The exterior of the working motor is provided with a transmission part, and the transmission part is used for the transmission between adrive gear or a standby gear and a driven gear. An output shaft of the working motor is provided with the drive gear, and the output shaft of the standby motor is correspondingly provided with the standby gear which has the same structure as the structure of the drive gear. The polyimide film production equipment is provided with the driven gear. The device provided by the invention can be switched to the standby motor when the motor has a fault, and gives an alarm for reminding an operator of the damage of the motor for processing, thereby reducing the impact on production from the damage ofthe motor, and reducing the possibility of an accident.

Description

technical field [0001] The invention relates to the technical field of polyimide film production equipment, in particular to a polyimide film production equipment fault warning device. Background technique [0002] Polyimide film includes two types of polyimide film of homophenylene type and biphenyl type polyimide film. The former is made of pyromellitic anhydride and diaminodiphenyl ether, and the latter is made of biphenyltetracarboxylic acid diphenyl Anhydride and diphenyl ether diamine (R type) or m-phenylenediamine (S type) in the system. [0003] The film preparation method is as follows: polyamic acid solution is cast to form a film, stretched, and then imidized at high temperature. The film is yellow and transparent, with a relative density of 1.39-1.45. It has outstanding high temperature resistance, radiation resistance, chemical corrosion resistance and electrical insulation performance. It can be used for a long time in the air at 250-280 °C. The glass transit...

Problems solved by technology

[0007] This polyimide film production device for automatically wiping the release agent can automatically and evenly wipe the release agent to the edge of the strip during the production process, avoiding the problem of broken edges and ensuring the quality of the film. However, due to polyimide The film production process requires uninterrupted production for many years, and it usually stops once every 3 to 5 months, so it cannot be stopped during the production process. In the production workshop, the temperature is high, and the motor is often damaged, which may seriously cause production failure. ACCIDENT
