Principle and Application of Advanced Winding Equipment

,

This state-of-the-art equipment is engineered for optimal performance in the production of pole sheets. It features an integrated system comprising unwinding, front and rear tension control, as well as front and rear correction control. The stretching mechanism and preheating (applicable only to the positive electrode) enhance processing efficiency. Our advanced roll pressing ensures improved density of the coating layer and precise thickness accuracy. The equipment supports a seamless transition from constant tension unwinding to constant pressure rolling, and culminates in an automated winding process. Furthermore, it enables historical data queries and exports, provides real-time display of key parameters, and includes a problem alarm system for traceability of issues. As a leading China suppliers and factory, we are committed to delivering high-quality solutions that meet industry standards.
