IV. Equipment Basic Functions

This equipment is suitable for synchronous dual-edge trimming, folding, and heat-sealing shaping after vacuum packaging of soft pack batteries.

– Folding mechanism adopts specially designed rollers that match the geometric groove curve of the battery edge, ensuring a perfect fold effect.

Operating Procedure:

The operator manually places the battery into the clamp.

Upon dual-hand simultaneous start, the cylinder presses down to secure the cell, then the clamp automatically moves through:

1. Edge flattening roller,

2. Rotary cutter,

3. First-stage folding roller,

4. Second-stage folding roller,

5. Third-stage folding roller,

6. Heated sealing area for heat pressing (time adjustable).

After heat sealing:

l The clamp cylinder lifts,

l A vacuum manipulator picks up the cell and places it on the conveyor,

l The clamp returns to home position,

l The next cycle begins automatically.
