Battery Vacuum Liquid Injection & Hot Sealing Machine

Battery Vacuum Liquid Injection & Hot Sealing Machine

Applications:

This vacuum liquid injection & hot sealing machine is primarily designed for the absorption of electrolyte during the injection process of pouch and cylindrical batteries. It facilitates a more complete fusion with the electrode sheets in a vacuum environment. Additionally, it is suitable for the vacuuming and heat-sealing pre-encapsulation of pouch batteries after electrolyte injection. The machine achieves this through precise control of the vacuum pumping box and pneumatic heat-sealing components, automatically completing the vacuum heat-sealing of the aluminum-plastic shell of the battery.

Features and Benefits:

1.The sealing head is made of copper for efficient heat transfer, saving energy and improving work efficiency, making it more energy-efficient compared to similar products.
2.The pressure of the upper and lower sealing heads can be adjusted through a pressure regulating valve to meet different process parameter requirements.
3.The upper and lower sealing heads are driven by cylinders and guided by two linear guide sleeves, ensuring flexible movement and accurate guidance to meet the parallelism requirements after sealing.
4.Changes inside the chamber can be observed through a transparent window during operation.
5.It can adapt to batteries of different specifications, and adjustment is simple and convenient.
6.The machine adopts a split design of the main unit and control box, allowing it to work inside a glovebox or on a production line.
7.The product features multi-cycle operation, aiding in more thorough fusion of the electrolyte.
8.The upper chamber is driven by a cylinder and guided by two linear guide sleeves, ensuring flexible movement and accurate guidance to meet the sealing requirements.
9.It has an attractive appearance, compact size, and light weight.
10.PLC + touchscreen control for easy and intuitive operation.
