What Knowledge Should I Know After Purchasing A Vacuum Packaging Machine?

Oct. 22, 2021

We can see vacuum packaging products everywhere. The development and maturity of vacuum technology have played a big role in the development of many industries. It has solved many previous deficiencies and expanded the scope of the sales market many times. Therefore, its use is highly recognized by customers. Then, what knowledge should be understood after purchasing a vacuum packaging machine for the first time?

1. Vacuum

Vacuum operation is the first and very important step of the whole process. We need to prepare the packaging bags that need to be evacuated in advance, arrange them, and close the vacuum lid at the same time, and now we can start vacuuming. At the same time when the bag is vacuumed, the pointer of the vacuum gauge also rises, until the rated vacuum degree is reached, the vacuum pump stops working. In the process of vacuum work, the solenoid valve IDT also works, heat-sealing the vacuum of the air chamber, and the heat press frame remains in place.

2. Heat sealing

The solenoid valve is disconnected, and the outside atmosphere can enter the heat-sealed air chamber through the upper air inlet, so that the pressure difference between the vacuum chamber and the heat-sealed air chamber becomes larger, and the heat-sealed air chamber will be inflated and expanded, prompting the upper heat press frame to move toward Move down to press the bag mouth; at this time, the heat-sealing transformer can work and seal at the same time; at the same time, the time relay works, and the heat-sealing is finished after a few seconds.

3. Regain

Two-position two-way solenoid valve 2DT is open, the atmosphere enters the vacuum chamber, the pointer of the vacuum gauge returns to zero, the heat press frame is reset by the return spring, and the vacuum chamber is opened.

4. Loop

Move the above-mentioned vacuum chamber to another vacuum chamber, that is, enter the next working process, the left and right chambers work alternately, cyclically.
