Double-chamber vacuum packaging machine operation method: First: turn on the power supply to ensure that the vacuum pump is not reversed; then: set the pumping time, heating time, pumping time, the customer can test several times, the heating time is generally set at 2 according to the thickness of the bag. -4 seconds; three: close the upper cover of the device, the vacuum pump starts to draw air from the studio, when the set pumping time is reached, the vacuum pump stops working, then the pressure valve automatically opens, the airbag is inflated, the airbag is inflated The plate, the phenolic plate and the heating strip are integrally pressed down to the sealing portion, and at the same time, the heating strip can be heated electrically. When the sealing of the packaging bag is completed, the heating bar stops heating and is continuously cooled, the deflation valve is automatically opened, the air is placed, and the air is opened. Cover, complete a work cycle.
The continuous automatic vacuum packaging machine process description: the upper and lower membranes of the continuous packaging machine adopt the film, the upper film uses the composite film, the lower film uses the stretch film, and the lower film is driven by the chain to drive into the molding die, in the molding die. The inside is formed by heating and air pressure, so that the lower film is stretched out to the desired groove shape, and the product to be packaged in the swinging area (through the pendulum device) is placed in the stretched lower film, along with the chain. The forward running enters the sealing mold, and the upper film is attached to the lower film in the sealing mold, first vacuuming and then sealing (sealing the upper and lower membranes together). The venting, mold reduction, and packaged product continue to run forward, first printing each product's production date through a mobile coding system. The product is cut transversely into a single row in the cross-cutting zone, and then the product is longitudinally slit by a slitting device so that each product is individually formed. The device also attaches a cursor-aligned color film system to save costs for the user. The user is equipped with a waste edge material recovery suction cylinder system to maintain environmental sanitation.
