Hydraulic Calendering Machine Unwinding and Rewinding Unit XN-FSJ300

Product Introduction
This automatic unwinding and rewinding unit is designed for material roll unwinding and winding. It can be integrated with a hydraulic calendering machine to realize continuous processing of battery cathode and anode electrode sheets. The system is also suitable for unwinding and rewinding of optical films, functional films, and other flexible sheet materials.

Product Features
Unwinding and rewinding adopt servo motor automatic tension control, ensuring stable and uniform winding quality.
Both unwinding and rewinding units are equipped with automatic deviation correction, providing high winding precision.
Independent electric control system enables stable and reliable operation.
Modular structure with separate unwinding and rewinding units allows flexible configuration.
Designed to work in combination with hydraulic calendering machines for integrated operation.
