Flattening device for producing polyimide film

Abstract

The invention discloses a flattening device for producing a polyimide film, relates to the related field of polyimide film production, and aims to solve the problems that due to the fact that a flattening roller is directly used for flattening a polyimide film at present, the flattening roller can be stopped rotating, slurry is accumulated on one side of the flattening roller, and the flattening efficiency is influenced. A connecting frame comprises a connecting top plate, side baffles are fixedly connected to the front end and the rear end of the upper end of the connecting top plate, and a film flattening face is arranged on the portion, along the position between the two side baffles, of the upper end face of the connecting top plate; the connecting frame is provided with a first rolling unit, a second rolling unit and a third rolling unit, and rolling assemblies are arranged on the first rolling unit, the second rolling unit and the third rolling unit; and each rolling assembly comprises a lower rolling piece, each lower rolling piece comprises a plane part, a rolling part is arranged on one side of each plane part, and a connecting part is arranged on the other side of each plane part.

Description

technical field [0001] The invention relates to the field related to the production of polyimide films, in particular to a flattening device for producing polyimide films. Background technique [0002] Casting machine refers to the special equipment for making cast film. A high-precision electronic ceramic casting machine is used to use alumina as the main raw material for ceramic casting. Firstly, the pulverized powder is mixed with a binder, a plasticizer, a dispersant, and a solvent to make a slurry with a certain viscosity. It flows down from the hopper and is coated on the special base belt, and then the film is flattened by a flattening device, and after drying and curing, the film that becomes the green belt is peeled off from the top, and then the green belt is adjusted according to the size and shape of the finished product. For processing such as punching and lamination, it is made into a finished blank to be sintered. [0003] The current flattening device direc...
