The electrode sheet base material from the unwinding device enters the swing arm tension system after automatic deviation correction. After tension adjustment, it proceeds to the coating head where electrode slurry is applied according to programmed settings. The coated electrode sheet enters the oven for hot air drying. Tension is adjusted throughout the process, with winding speed synchronized to coating speed. Automatic correction maintains center position during winding.

Comprising servo unwinding, tension-controlled unwinding shaft, and automatic deviation correction system. Maintains constant tension through sensor feedback to tension controller.

Absorbs speed variations and space fluctuations during coating intervals. Adjusts substrate tension via swing arm position to maintain synchronization between unwinding and coating speeds.

PLC-controlled system with precision mechanical and opto-mechanical integration. Features extrusion die, coating roller, drive motor, optical fiber sensors, and high-performance pneumatic components. Supports continuous and intermittent coating modes with programmable parameters.
