Embodiment

[0020] A rewinding device for polyimide film production, including an electrostatic precipitator 1, a movable rewinding support 7 and an active rubber roller 3; the upper end of the movable rewinding support 7 is provided with a groove for placing the winding The reel of the film; the cylinder 8 is installed at the bottom of the support, and the inclination angle of the support is adjusted through the expansion and contraction of the piston rod of the cylinder, thereby controlling the distance between it and the active rubber roller, and controlling the speed and tension of film winding;

[0021] In this embodiment, a winding motor 9 is arranged below the driving rubber roller 3, and the winding motor 9 is connected to the rotating shaft of the driving rubber roller 3 through a belt. By controlling the winding speed of the winding motor 9, the winding speed and The tension is adjusted, the control is flexible and convenient, and the production efficiency is effectively improved...

Abstract

The invention relates to a winding device for polyimide film production. The winding device for polyimide film production comprises an electrostatic dust collection device, a movable winding support and a driving rubber roller. The angle of the movable winding support is adjusted through an air cylinder installed at the bottom, and the driving rubber roller is connected with a motor below through a belt. A rolling shaft is arranged in the electrostatic dust collection device, and an electricity removal roller is arranged below the electrostatic dust collection device. According to the winding device, the electrostatic field can be used for dedusting polyimide, meanwhile, the subsequent rubber rollers eliminate static electricity and flatten the film, and the rotating serrated knife is further arranged on the driving rubber roller so that the film can be cut off conveniently.

Description

technical field [0001] The invention belongs to the field of polyimide film production equipment, and in particular relates to a winding device for polyimide film production. Background technique [0002] Polyimide is a general term for a class of aromatic heterocyclic polymers containing imine rings in the main chain. This type of compound has excellent thermal stability, chemical corrosion resistance and mechanical properties; it is the best film in the world Class insulating materials are often used in the production of flexible circuit boards and other high temperature resistant electrical appliances. [0003] Polyimide is usually made into a film for use, so in the production process of polyimide products, winding and slitting is also a relatively important process. In the process of film winding, problems such as wrinkles are often caused by uneven film tension; especially when the film is cut during slitting and rewinding, the tension at the slitting point changes su...
