The working process of the vacuum sealing machine

Can automatically extract air inside the bag, achieving complete after vacuum sealing process. Yi ke and blended into nitrogen or other gases, and then complete the sealing process. Vacuum packing machine is often used in food industry, because after vacuum packaging, food antioxidant, to achieve the purpose of long-term preservation.

vacuum packaging machine working process

1, vacuum, vacuum chamber cover, vacuum pump, vacuum chamber began pumping air into vacuum state, bags in vacuum at the same time, the vacuum degree of vacuum gauge pointer to rise to the rated ( By the time relay ISJ control) Vacuum pump stop working, and the vacuum stopped. In a vacuum, at the same time the work of two work the 3-way magnet valve (IDT, vacuum heat sealing, thermal in situ.

2, heat sealing, IDT, the outside air through the upper air inlet into the heat sealing gas chamber, using vacuum chamber with heat sealing air chamber, the pressure difference between the heat sealing chamber inflated, their hot pressing down, pressure mouth; Heat sealing transformer work at the same time, began to seal; 2 sj working at the same time, time relay, and a few seconds after the movement, heat sealing end.

3, back to the gas: 2 dt tong two two-way solenoid valve, air into the vacuum chamber, vacuum gauge pointer back to zero, and hot pressing on reset spring reset, vacuum chamber open cover.

4, cycle: move the vacuum chamber to another vacuum chamber, namely into the next process, around two rooms work alternately, cycling.
