Technical Field

[0001] The utility model relates to the technical field of vacuum devices, in particular to a packaging bag processing vacuum device. Background Art

[0002] Vacuuming a packaging bag usually refers to extracting the air from the packaging bag to achieve a predetermined vacuum level in the packaging bag, in order to extend the shelf life of the food and prevent the food from spoiling.

[0003] Application number: 201920525345.7, a food vacuum packaging device, a movable cover is movably hingedly provided on the top of the box body, a working chamber is provided in the box body, two rows of placement grooves are longitudinally opened in the working chamber, and a lower pressure plate is longitudinally fixedly arranged in the working chamber outside each row of the placement grooves, and an upper pressure plate is movably connected downward at the bottom of the movable cover and the corresponding positions of the two lower pressure plates, and a heating plate is fixedly connected to the bottom of the upper pressure plate and the top of the lower pressure plate, and a vent hole is horizontally opened on the box body on one side of the working chamber, and an interface is fixedly connected to the outer wall of the box body on the outer side of the vent hole, and an air pump is movably connected to the outer side of the interface.
