Problems solved by technology
During the production process of polyimide film, it needs to be dried, and it needs to be conveyed during the drying process. However, during the transmission process, a large amount of iron filings and dust will inevitably be generated due to friction during the operation of the chain and sprocket. , and the iron filings and dust generated will fall on the film it conveys, causing film pollution

The invention proposes a polyimide casting film drying equipment, comprising: a drying box with an inlet and an outlet and a conveying line inside the drying box, the conveying line includes a drying box arranged side by side from the inlet to the outlet of the drying box The conveying roller, the sprocket and chain installed at both ends of the conveying roller, and the power mechanism, wherein: the inside of the drying box is provided with the first power chamber and the second power chamber which are arranged on both sides of the direction of the conveying roller; one end of the conveying roller Extend through the side wall of the first power chamber to the first power chamber and set a first rotary dynamic seal at the joint with the first power chamber, and the other end of the transmission roller passes through the side wall of the second power chamber to extend into the first power chamber. The second power chamber and the second rotary dynamic seal are installed at the junction with the second power chamber; the sprocket and chain installed at one end of the conveying roller are located in the first power chamber, and the sprocket and chain installed at the other end of the conveying roller are located in the second power chamber Two power room. The invention can effectively avoid the problem of film pollution.
Description
Technical field [0001] The present invention relates to the technical field of casting film drying equipment, specifically to a polyimide casting film drying equipment. Background [0002] Polyimide film is a kind of organic polymer material made of film, which has outstanding high temperature resistance, radiation resistance, chemical corrosion resistance and electrical insulation performance, suitable for flexible printing circuit board substrate and a variety of high temperature resistant motor electrical insulation materials, which in aviation, aerospace, electronics, liquid crystal and other fields have been widely used, polyimide film production is divided into two steps, the first step of the synthesis of polyamide acid solution, the second step of the polyamide acid solution for casting, stretching, iminoization and winding into a polyimide film. Polyimide film in the process of making, need to dry it, drying over the need to transmit, but because in the transmission proc...
