A liquid injection machine discharge sealing device

Abstract

The utility model provides a kind of liquid injection machine discharge sealing device, belong to battery liquid injection sealing technical field, including liquid injection machine, liquid injection machine has discharge box, discharge box includes box and sealing door, discharge box is equipped with the air pipe being communicated with its inside, solenoid valve is fixedly installed on air pipe, solenoid valve is electrically connected with opening and closing device, opening and closing device is used to control the switch of solenoid valve, to realize the start and stop of air pipe to the delivery of protective gas in box.This scheme is by respectively setting air pipe, solenoid valve and opening and closing device on discharge box, when battery packaging discharges, solenoid valve switch is controlled using opening and closing device, realize the delivery of protective gas in air pipe to discharge box, form micro positive pressure, so that protective gas continues to flow to discharge box outlet, prevent external air into discharge box, effectively isolate moisture, oxygen and other components in external air, which cause adverse effects on battery cell, improve the stability and sealing property of discharge box internal environment.
