Abstract

The invention discloses a coating machine for polyimide film preparation. According to the technical scheme, the coating machine comprises a first machine body, a second machine body, a first tensioning device, a smearing device and a second tensioning device, wherein connecting buckles are arranged on the two sides of the first machine body and the two sides of the second machine body; universalwheels are fixedly mounted at the bottom of the first machine body and the bottom of the second machine body; the first machine body and the second machine body are movably connected through the connecting buckles; the first tensioning device is arranged on the inner wall of the first machine body; the smearing device is arranged on the left side of the first tensioning device and fixedly mountedon the inner wall of the first machine body; and the second tensioning device is fixedly mounted on the inner wall of the second machine body. The coating machine has the beneficial effects that a first glue storage groove and a second glue storage groove are formed in the two sides of the bottom of a glue outlet barrel, an L-shaped cam shaft is fixedly mounted on the inner wall of the glue outletbarrel, a push plate is fixedly mounted at the output end of the L-shaped cam shaft, thus the L-shaped cam shaft is pushed circularly, meanwhile, the first glue storage groove and the second glue storage groove are subjected to glue supplementing through cooperation of a first glue supplementing hole and a second glue supplementing hole, and the effects of energy saving and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of coating devices, in particular to a coating machine for preparing polyimide films. Background technique [0002] As we all know, polyimide film is one of the earliest commodities of polyimide. It is used for slot insulation of motors and cable wrapping materials, and is widely used in the above fields. Acetic anhydride and DMF are mixed in a certain ratio, and then mixed with the polyamic acid solution in a mass ratio of 100:30-100:40, stirred evenly in an environment below 0 °C, and the prepared material is coated with a coating machine Apply glue on the release film, put it in an oven at 120°C and 300°C successively, and obtain a polyimide film after dehydration and curing. [0003] The prior art has the following deficiencies: in most cases, the existing coating machines for the preparation of polyimide films are huge, heavy and take up space, are very difficult to operate, have very low work efficien...
