Automatic Roll Grooving Machine For Cylindrical Cell Production Plant

Introduction

This equipment can be used in the rolling groove process of rechargeable NiMH, NiCd and cylindrical lithium battery. Through PLC, intermediate relay and time relay, the grooving machine controls the coordinated action of each cylinder, the motor drives the machine body to run at high speed, and the cylindrical steel shell with electric core is uniformly and automatically grooved. We provide a full ranges of Li ion cell making Machine.
