Calendering&slitting machine

Equipment Introduction

A kind of positive/negative electrode sheet which is formed into a roll after coating is passed through a continuous hydraulic roller device, and the electrode sheet is uniformly milled to the thickness required by the process, and then slit into a plurality of electrode sheets which meet the width required by the process, and wound up in a neat roll.

Functional Features

1. "One key" fault self-test technology, can realize the equipment electrical system intelligent self-test, fault location, fault information prompt function; 

2. Closed-loop control of the roll seam pressure and closed-loop control of the position of the dual-mode;

3. Adoption of IO-LINK connecting technology, which improves the control accuracy and the level of intelligent sensors;

4. Rising process of the servo-proportional valves running fuzzy PD algorithms to quickly adjust the servo-proportional valves Opening degree, to ensure that the two sides of the main roller ascending roller synchronization error within 0.5s;

5. master cylinder pressure and bending cylinder pressure double PID regulation, pressure fluctuation value in the roller pressure + 0.5T or less.
