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.
