Do You Understand The Working Principle Of Tea Chamber Vacuum Machine?

When the tea chamber vacuum machine is working, manually place the filled packaging bag in the cavity, and place the mouth of the bag on the heat sealer, close and close the vacuum chamber cover, and lean against the seal ring on the vacuum chamber cover. The vacuum chamber is sealed and the system is controlled at the same time. A series of actions such as vacuuming, pressing the mouth of the bag, heating and sealing the heater, cooling, releasing the vacuum in the vacuum chamber, and lifting the lid of the chamber vacuum machine are automatically completed according to the working procedure.

1. Vacuum: The chamber vacuum machine is closed and the vacuum pump is working. The vacuum chamber starts to evacuate. At the same time, the vacuum in the packaging bag is raised, and the pointer of the vacuum gauge rises. When the rated vacuum is reached, the vacuum pump stops working. While the vacuum is working, the two-position three-way solenoid valve IDT works, heat-seals the vacuum chamber, and the hot-pressing frame stays in place.

2. Heat seal: The outside atmosphere enters the heat seal air chamber through its upper air inlet. Using the pressure difference between the chamber vacuum machine and the heat seal air chamber, the heat seal air chamber is inflated and expanded, causing it to move down on the hot press frame. Hold the bag mouth; at the same time, the heat-sealing transformer works and starts to seal; at the same time, the time relay starts to work, and the heat-sealing ends after a few seconds.

3. Air return: The two-position two-way solenoid valve 2DT is turned on, the atmosphere enters the vacuum chamber, the pointer of the vacuum gauge returns to zero, the hot pressing frame is reset by the reset spring, and the chamber vacuum machine is opened.

4. Circulation: Move the above chamber vacuum machine to another chamber vacuum machine, that is, enter the next working process, the left and right chambers work alternately, and reciprocate.
