Battery electrode, wave edge, stretching, flattening, tension control, corrugated roll, plastic deformation

2: Introduction: 

Used to eliminate the wave edges produced during the rolling process of continuously or continuously slit-coated battery electrodes.

3: Technical Specifications:

• Traction roll diameter: φ200mm.

• Pinch roll diameter: φ120mm.

• Tension adjustment range: 10~1000N.

• Tension control accuracy: ≤±2N.

4: Technical Features:

• Includes tension isolation traction, swinging roll stretching, tension detection, and auxiliary threading devices.

• A corrugated roll is made according to the product width, and appropriate tension is applied to the material strip.

• Plastic deformation occurs in the non-coated foil area, reducing uneven deformation along the entire length of the electrode.

• This eliminates or reduces the formation of wrinkles in the transition area.

• Traction roll specification: φ200mm, with a hard chrome plated surface.

• Pinch roll specification: φ120mm, with a tri-polymer rubber surface.

• PLC + low-friction cylinder + servo motor dual closed-loop tension control, with a digital display showing the tension value.

• Tension adjustment range: 10~1000N, control accuracy ≤±2N.

5: Application: 

Battery electrode production line.
