Advantages of vacuum packaging machine

If you want to create maximum benefits for yourself within the specified time, you must ensure that your food packaging production line is running well, and there will be no errors in the production process, so as to avoid the impact of errors and failures as much as possible. Businesses get the most benefit. The level of automation in the manufacturing industry is constantly improving, and the scope of application is expanding. Automation in the packaging machinery industry is changing how the packaging process moves and how packaging containers and materials are processed. The packaging system that realizes automatic control can greatly improve the production efficiency and product quality, significantly eliminate the errors caused by the packaging process and printing and labeling, effectively reduce the labor intensity of employees and reduce the consumption of energy and resources. Revolutionary automation is changing how the packaging machinery industry is manufactured and how its products are transported. The designed and installed automatic control packaging system plays a very obvious role in improving the product quality and production efficiency of the packaging machinery industry, eliminating processing errors and reducing labor intensity. Especially for the food, beverage, pharmaceutical, electronics and other industries, it is crucial. The technology of automatic device and system engineering is further deepened and applied more widely.

Working process of vacuum packaging machine:

1. Vacuum: when the vacuum chamber is closed, the vacuum pump works, the vacuum chamber starts to be evacuated, the inside of the packaging bag is vacuumed at the same time, the pointer of the vacuum gauge rises, and the rated vacuum degree (controlled by the time relay ISJ) is reached. The vacuum pump stops working and the vacuum stops. While the vacuum is working, the two-position three-way solenoid valve IDT works, the heat-sealing air chamber is vacuumized, and the heat-pressing frame remains in place.

2. Heat sealing: When the IDT is broken, the outside air enters the heat sealing air chamber through the upper air inlet hole. Using the pressure difference between the vacuum chamber and the heat sealing air chamber, the heat sealing air chamber is inflated and expanded, so that the upper hot pressing frame is lowered. Move and press the bag mouth; at the same time, the heat-sealing transformer works and starts to seal; at the same time, the time relay 2SJ works, and the heat-sealing ends after a few seconds.

3. Air return: The 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 hot-pressing frame is reset by the return spring, and the vacuum chamber is opened.

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