Automatic Pouch Cell Rotary Top and Side Hot Sealing Machine 

I. Functions and Working Process

l Function:

Performs thermal sealing on the top and side edges of square pouch lithium-ion cells, or top edge sealing for pouch cylindrical cells.

l Working Process:

Place the battery into the battery tray. Press the two control buttons on the front of the operation panel; the machine will automatically rotate the turntable to bring the battery into the sealing position. The lower and upper heat sealing bars will perform thermal sealing on the battery edge. After holding the pressure for the specified time, the heat sealing bars will return to their original positions. When the next battery enters, the previously sealed battery can be removed.

If no battery is placed in the tray, the corresponding upper and lower heat sealing bars will not operate.

IV. Process Performance

1. Rotary 4-station structure, with two sets of heat sealing heads

2. Top and side sealing temperatures (ambient ~250°C) are independently adjustable

3. For square pouch cells, top and side sealing can be performed simultaneously. Both soft and hard sealing processes can be achieved by changing the sealing strips

4. Touchscreen display operation, controlled by PLC

5. Top and side sealing pressures and cylinder strokes are independently adjustable

6. Top and side sealing times (0–99.9 seconds) are independently adjustable

7. The front of the machine is equipped with a safety light curtain. If a body enters during operation, the machine will immediately reset automatically—safe and reliable
