AI Technical Summary

Technical Problem

In existing technologies, when packaging bags are vacuum sealed, the opening is squeezed by the sealing gasket, which reduces the air extraction efficiency and makes it impossible to quickly extract the air from the packaging bag.

Method used

A horizontal plate is installed inside the annular sealing gasket for quick extraction of gas from the packaging bag through the guide hole, and the snap-fit ​​assembly is used to keep the sealing gasket stable and pressurized, thereby improving the extraction efficiency.

Benefits of technology

This technology enables rapid extraction of gas from the bag even when the sealing gasket squeezes the opening of the packaging bag, thus improving the efficiency of vacuum sealing.

Abstract

The utility model relates to vacuum sealing machine technical field especially simple type plastic packaging bag vacuum sealing device, its technical scheme: including shell, the shell bottom is fixed with bottom shell, the vacuum pump is installed in the bottom shell, the shell upper end front side is equipped with the sealing cavity, the sealing cavity bottom rear side is equipped with the air extraction hole, the sealing cavity bottom and located the air extraction hole peripheral fixed sealing pad, the sealing cavity bottom front side is fixed with the electric heating wire, the sealing cavity is hinged with the flap, is provided with same sealing pad in the sealing cavity in the flap. The utility model sets up the transverse plate that stretches out in the annular sealing pad of air extraction, when air extraction, utilizes the transverse plate and inserts into the packaging bag, can quickly extract the gas in the packaging bag through the flow guide hole, effectively avoids the packaging bag opening to be extruded by the sealing pad, leads to the problem that the gas is difficult to discharge outward, improves the vacuumizing efficiency.
