Abstract
Description
Technical Field
[0001] The utility model relates to the field of polyimide film production, in particular to an auxiliary winding device for the production and processing of polyimide films. Background Art
[0002] Polyimide, a general term for a class of aromatic heterocyclic polymers containing an imide ring in the backbone, is one of the best-performing organic polymer materials overall. Polyimide, synthesized from pyromellitic dianhydride and p-phenylenediamine, has a thermal decomposition temperature of 600°C, making it one of the most thermally stable polymers to date.
[0003] Polyimide is typically manufactured into thin films for use. During the production of polyimide products, a winding device is required to wind the produced polyimide film. During the film winding process, the polyimide film near the winding roller is prone to wrinkling due to slack, affecting the quality of the finished product. Furthermore, when the winding machine is docked with the front equipment, the discharge roller heights of different front equipment vary. Therefore, most manufacturers customize the winding machine based on the discharge roller height, resulting in high costs. Based on this, the present invention proposes an auxiliary winding device for polyimide film production and processing. This auxiliary winding device integrates four components: a front guide shaft, a film guide shaft, a rear guide shaft, and a winding shaft. The front guide shaft can be adjusted according to the height of the discharge roller by a servo, while the film guide shaft quickly guides the film introduced by the front guide shaft to the rear guide shaft. The rear guide shaft adopts a floating structure, which prevents the film from slack or breakage due to excessive tension. This provides excellent performance and does not affect the quality of the film winding. Utility Model Content
