Description

Technical Field

[0001] The utility model relates to the field of vacuum packaging machines, and particularly relates to a new type of food vacuum packaging machine. Background Art

[0002] A vacuum packaging machine is a device commonly used for packaging products such as food. When an operator puts the product to be packaged into the vacuum chamber, the door of the vacuum chamber is first closed. Then the vacuum packaging machine is started, and the control system begins to work. The vacuum pump system starts to extract the air in the vacuum chamber, and at the same time the sealing system starts to seal the packaging bag or container. As the air is extracted, the air pressure in the vacuum chamber gradually decreases, forming a vacuum environment. Once the preset vacuum degree is reached, the control system stops the work of the vacuum pump system and heats the sealing system to make the sealing strip closely combine with the packaging bag or container to ensure the sealing property. After the sealing is completed, the sealing system stops heating, and the sealing strip cools and solidifies to complete the entire packaging process. The main purpose of vacuum packaging is to extend the shelf life of products such as food and prevent oxidation and spoilage of the products by oxygen, moisture, etc.

[0003] When food is conveyed by a conveyor belt, the vacuum extraction and sealing of the vacuum packaging machine are not tight.

[0004] Therefore, there is an urgent need to provide an improved technical solution to solve the above technical problems. Summary of the Utility Model
