Food full-automatic vacuum bag packing machine

The invention discloses a food full-automatic vacuum bag packing machine which comprises a packing film emptying mechanism, a filling mechanism, a side sealing mechanism, a bag cutting mechanism and a vacuum cavity rotary table mechanism in sequence. The packing film conveying lines of the packing film emptying mechanism, the filling mechanism, the side sealing mechanism and the bag cutting mechanism are located on the same straight line. The vacuum cavity rotary table mechanism comprises a disc-shaped rotary table, the edge of the rotary table is tangent with the position of the bag cutting mechanism, and a material bag blanking mechanism is arranged below the vacuum cavity rotary table mechanism. The side sealing mechanism can perform automatic feeding and heating packing. A rotary table device is arranged at the position of the filling mechanism, raw materials are filled into material bags after being quantitatively measured by a raw material conversion device (namely a measuring cup), the raw materials in the material bags are approximately rectangular or oval, and the weight and the shape of each bag of products keep the same. For the last sealing ports of the material bags, the material bags directly enter a vacuum cavity to be vacuumized and sealed, and meanwhile the material bags can slide off automatically by rotating a base plate.
