Description

Leak-proof air sealing device of vacuum sealing machine Technical Field The application relates to the technical field of vacuum sealing machines, in particular to an anti-leakage air sealing device of a vacuum sealing machine. Background Vacuum sealers play a vital role in many industries, such as food, electronics, and the like. The air in the packaging bag can be pumped out to form a vacuum environment, and then the sealing operation is carried out, so that the quality guarantee period of the article is effectively prolonged, and the article is protected from being damaged by external air, moisture, dust and the like. The vacuum sealing machine mainly comprises a machine body, a vacuum pump, a heating device, a sealing structure and the like.
