Vacuum packaging machine operation and equipment functions

Zhucheng Senyue vacuum packaging machine talk about the operation process and equipment functions of vacuum packaging machine

Heat sealing: The heating time relay is energized and the heating circuit is switched on. Nichrome is heated. The air chamber solenoid valve is de-energized, the valve core is reset, the passage of the valve and the outside is opened, so that the atmosphere enters the heat-sealing air chamber through the upper air inlet hole thereof, and the pressure difference between the vacuum chamber and the heat-sealing air chamber is utilized, and the heat sealing gas is used. The inflation of the room inflates the thermal heating strip and presses the bag tightly to begin sealing and print the date.

Cooling: At the same time when the heating time relay is de-energized, the cooling time relay is energized, and the cooling function is to use the residual heat to compress the bag opening to prevent the bag mouth from shrinking during cooling, so as to maintain the flat appearance of the bag mouth. After the set cooling time is reached, the cooling time relay is de-energized. (Cooling time relay is installed in the electric appliance, and it is adjusted well before leaving the factory.) The circuit of the bleeder solenoid valve is connected, and the solenoid valve is energized. The valve opens and the atmosphere enters the studio. The heating head is reset, and when the pressure of the working chamber is equal to the outside air pressure, the vacuum chamber cover is automatically opened and the limit switch is reset, ie, a packaging procedure is completed.
