Lithium Battery Precision Extrusion Coating Machine
Prosuct Specification
The electrode substrate mounted on the unwinding device enters the unwinding tension system after automatic deviation correction. After adjusting the unwinding tension, it enters the coating head. The electrode is coated according to the setting procedure of the coating system. After coating the wet electrode into the oven by hot air drying. The dry electrode is adjusted by the tension system, and the winding speed is controlled to keep it in sync with the coating speed. The electrode is kept in the set position by the automatic rectifying system, and the rewinding device is used to rewind the chip.
