[0025] Among them, the packaging bag containing food to be packaged is placed on the material rack component 2, the vacuum component 3 is used to vacuum the packaging bag, and the first hot pressing plate 23 and the second hot pressing plate 24 constitute a hot pressing sealing component, which is used to hot pressing and sealing the vacuumed packaging bag.

[0026] One end of the third electric cylinder 34 is connected to the vacuum cover 31 via a driving plate 35 .

[0027] The second hot pressing plate 24 is located above the first hot pressing plate 23 , and a sealing position is formed between the first hot pressing plate 23 and the second hot pressing plate 24 , and the second hot pressing plate 24 is electrically connected to the first hot pressing plate 23 .

[0028] Among them, multiple groups of packaging bags are arranged and placed on the placement plate 22, and the parts of the packaging bags to be sealed are located at the hot-pressing sealing position. The elastic rope 27 limits and fixes the multiple groups of packaging bags. When the first electric cylinder 21 is working, it drives the placement plate 22 to slide, and the placement plate 22 drives the multiple groups of packaging bags on the upper part to move into the vacuum area;

[0029] The third electric cylinder 34 drives the vacuum cover 31 downward, and a seal is formed between the lower part of the vacuum cover 31 and the substrate 1 and the placement plate 22. After the seal is formed, the vacuum pump 32 operates to perform a vacuum operation through the hose 33, and the inside of the vacuum cover 31 is evacuated to a vacuum state, that is, the packaging bag is evacuated to a vacuum state.

The first electric cylinder 21 works to drive the placement plate 22 to slide, and the placement plate 22 drives the multiple groups of packaging bags on its upper part to move into the vacuum area. The third electric cylinder 34 works to drive the vacuum cover 31 to move downward, and the lower part of the vacuum cover 31 is sealed with the base plate 1 and the placement plate 22. After sealing, the vacuum pump 32 works to perform vacuum operation through the hose 33. The interior of the vacuum cover 31 is evacuated to a vacuum state, thereby evacuating the packaging bag to a vacuum state. After the vacuuming is completed, the second electric cylinder 25 drives the second hot pressing plate 24 to move downward, and the first hot pressing plate 23 and the second hot pressing plate 24 clamp the sealing portion of the packaging bag to be sealed to perform hot pressing and sealing.
