AI Technical Summary

Technical Problem

Existing technologies struggle to efficiently control the resin content during carbon fiber impregnation, and scraping or suction methods can easily cause the resin to adhere to the roller, resulting in reverse rotation and secondary impregnation.

Method used

It adopts an ultra-smooth roller and angle difference design, combined with vertical adjustment section and fine adjustment section, and achieves precise adjustment of roller height and angle through push section and glue push section, to prevent resin adhesion, and collects resin flow down through push plate.

Benefits of technology

It enables precise control of the resin content in the carbon fiber winding layer, avoiding secondary impregnation of the resin by reverse rotation on the roller, thus improving production efficiency and product quality.
