When packaging, the fixed heat sealing plate and the movable heat sealing plate seal the packaging film twice, and the pressing plate rotates with the rotating seat, so that the sauce flows to the side sealed by the fixed heat sealing plate, and the air in the packaging box is squeezed out by the vibration of the vibrator and the extrusion head of the packaging box, and then it is completely sealed by the movable heat sealing plate, and the air in the packaging box can be greatly reduced.
