Packaging bag sealing machine and packaging bag sealing method

Abstract

The invention discloses a packaging bag sealing machine. The packaging bag sealing machine comprises a machine body. A cutting device used for cutting packaging bags is arranged on the machine body. The machine body is further provided with a vacuumizing device and a sealing device, wherein the vacuumizing device draws out air in the packaging bags, and the sealing device seals the edges of the packaging bags. According to the packaging bag sealing machine, the cutting device, the sealing device and the vacuumizing device are arranged on the machine body at the same time, and therefore a series of steps comprising cutting, vacuumizing and sealing of the packaging bags can be completed. The packaging bag sealing machine has the advantages of being simple in structure and convenient to use. The invention further discloses a packaging bag sealing method. The packaging bag sealing method comprises the steps that the packaging bags are cut, one edge of each packaging bag is sealed, objects are put in the packaging bags, vacuumizing is conducted, and the other edge of each packaging bag is sealed. By the adoption of the packaging bag sealing method, the packaging bag of an appropriate length can be obtained through cutting according to the length of the packaged objects, and then packaging of the objects is conducted; and in this way, packaging bag materials are saved, and the packaging demands of objects of different lengths is also met.
