Product Description

Slot Die Extrusion Coating Coater Machine For Lithium ion Battery Production Line


 

1. Process Flow
The base material of the polar plate placed on the unwinding device enters the unwinding tension system after automatic correction, and enters the coating head after adjusting the unwinding tension. The polar plate is coated according to the setting procedure of the coating system. The coated wet electrode piece enters the oven and is dried by hot air. The tension of the dried pole piece is adjusted by the tension system, and the winding speed is controlled to synchronize with the coating speed. The pole piece is automatically rectified by the rectifying system to keep it in the set position, and is wound by the winding device.
