Automatic Roll to Roll Pouch Cell Die Cutter for Electrode Cutting

Function overview

1. The device is suitable for automatic die-cutting of lithium battery electrode.

1.2 Operation process:

The coil material of the pole piece is controlled by the variable frequency motor. After the tension float roller and the precision correction mechanism, the circulating conveyor belt of the highland wheat paper driven by the servo motor is sent to the die-cutting machine. After the die-cutting, the edge material is collected by the edge material receiving mechanism, and the pole piece automatically flows into the tray.

1.3 Action process:

Auto unwinding → Unwinding correction → Tension & Material storage → Receiving platform → Die-cut part → up-collection → Automatically drop into the receiving box
