Working principle: before the vacuum packaging machine starts to work, the bag mouth of the sealing packaging bag is placed in the first vacuum groove, and the gland is turned downwards, so that the pressing columns on two sides of the gland extend into and are clamped in the rubber plug holes on the bottom box. When the gland is buckled, the gear on the gland drives the rack to move towards the direction of the rack, so that the piston of the air suction cylinder is pulled by the rack, the pipeline of the vacuum system is vacuumized in the air suction cylinder, and negative pressure is formed in the pipeline. Wherein, because the pumping capacity of the pumping cylinder is larger, a larger negative pressure can be generated in the pipeline of the vacuum system in a short time. When the position switch on the bottom box 1 detects that the buckling of the gland 2 is in place, the sealing valve is conducted, the negative pressure of the vacuum system is utilized to generate a rapid and large-flow air flow adsorption force, the pressure column is rapidly adsorbed into the rubber plug hole by utilizing high-speed air flow, so that a sealing state is formed between the pressure column and the rubber plug hole, a user can work after closing the gland, the gland is not required to be pressed for a long time, the gland can be loosened after the vacuum in the system is established, the user operation is further facilitated, and the vacuumizing efficiency is improved.

And finally, closing the sealing valve, opening the evacuating valve, and vacuumizing the vacuum tank by using the vacuum pump to finally realize the purpose of vacuumizing the sealing bag.
After the vacuumizing treatment is finished, the vacuumizing valve, the sealing valve and the exhaust valve are opened, air reversely enters the vacuum system, the vacuum environment between the pressing column and the rubber plug hole is broken, the air suction cylinder reversely pulls the pressing cover to reset upwards under the action of negative pressure, the purpose that the pressing cover is automatically opened and reset is achieved, and finally the purpose that the pressing cover is automatically opened after the vacuumizing treatment is finished is achieved. After the vacuumizing is completed, the user does not need to manually open the gland, so that the operation of the user is facilitated, and the user is reminded that the vacuumizing is completed.
Compared with the prior art, when the gland is closed, the power mechanism drives the air suction cylinder to firstly establish a high-air-volume vacuum environment in the system, and after the gland is buckled in place, the high-air-volume air flow adsorption is utilized, so that the pressure column is rapidly adsorbed into the rubber plug hole, a sealing state is rapidly formed between the pressure column and the rubber plug hole, and sealing conditions are provided for later-stage vacuum pump adsorption. Therefore, the defect that the vacuum environment is built because the air leakage between the pressing column and the rubber plug hole is difficult to be compensated due to the insufficient air suction amount of the vacuum pump in unit time is overcome. The quick sealing and pressing of the gland are realized, and meanwhile, a power support is provided for the automatic opening of the gland. The evacuation efficiency is ensured while the operation of a user is convenient, so the evacuation device can be widely popularized and used.
