Description
Pouch Cell Second Sealing Machine – Vacuum Heat Sealer with Puncture & Waste Recovery
This Pouch Cell Second Sealing Machine is specifically designed for the final packaging of medium and small-size pouch lithium batteries after bayonet piercing. It performs vacuum extraction and hot press sealing to ensure hermetic encapsulation of battery cells.
Working Principle:
After the battery undergoes bayonet piercing, it is placed in the sealing machine. The equipment performs:
- Automatic puncture of the air bag
- Vacuum extraction within the sealed cavity
- Hot press sealing of the aluminum-plastic film
The cover cavity is driven by a cylinder and guided by linear guide sleeves, ensuring flexible movement and precise alignment for consistent sealing quality.
Key Features:
- Automatic Puncture Function: Integrated mechanism for piercing the air bag before sealing.
- Waste Liquid Recovery Device: Safely collects any expelled electrolyte during the vacuum process.
- Precision Guidance: Cylinder-driven cavity with linear guide sleeves ensures accurate positioning and tight seals.
- Copper Sealing Head: Made of copper material for excellent heat transfer, reduced power consumption, and improved energy efficiency compared to similar products.
- Adjustable Parameters: Upper and lower head pressure adjustable via pressure regulating valve to meet various process requirements.
- Corrosion-Resistant Cavity: Aluminum alloy construction resists corrosion and provides structural integrity.
- Flexible Vacuum Control: Vacuum degree adjustable from -90KPa to 0 (customer-provided vacuum pump required).
Applications:
- Second sealing of pouch lithium batteries after electrolyte filling and formation
- Vacuum packaging of medium and small-size pouch cells
- Battery R&D laboratories
- Small to medium-scale battery production
