Description

Technical Field

[0001] The utility model relates to the technical field of plastic sealing machines, in particular to an integrated vacuum plastic sealing machine. Background Art

[0002] The vacuum packaging machine can automatically extract the air in the packaging bag and complete the sealing process after reaching a predetermined vacuum degree. It can also be filled with nitrogen or other mixed gases to complete the sealing process. Vacuum packaging machines are often used in the food industry because after vacuum packaging, the food can resist oxidation and achieve the purpose of long-term preservation.

[0003] The existing Chinese utility model patent with reference announcement number: CN220616330U discloses an integrated vacuum plastic sealing machine, including a vacuum shell, the rear side wall of the vacuum shell is bolted with a vacuum motor, the movable end of the vacuum motor penetrates the rear side wall of the vacuum shell and is connected with a vacuum impeller, and the front side wall of the vacuum shell is fixedly connected with a plurality of connecting pipes distributed in a circumferential array. The utility model drives the vacuum impeller to rotate through the vacuum motor to discharge the gas in the vacuum shell, so that the vacuum shell is in a negative pressure environment, and the gas enters from a plurality of connecting pipes, thereby sealing the pipeline or packaging bag. The device has a simple structure and is easy to carry. The multi-dry connecting pipes can seal multiple packaging bags or pipelines, thereby improving work efficiency.

[0004] Because the plastic bag will deform based on the shape of the items inside the plastic bag after the air inside the plastic bag is sucked out, the existing vacuum laminator cannot limit the position of the edge of the opening of the plastic bag. The sealing position of the plastic bag may shift after the vacuum is drawn inside the plastic bag, resulting in the opening being unable to be completely closed, affecting the sealing operation. In addition, the existing laminator cannot maintain a certain relative pressure on the upper and lower sides of the seal when sealing, which may cause the seal to fail to fully bond, affecting the sealing effect.
