[0062] like Figures 1 to 12 As shown, this embodiment proposes a fully automatic integrated packaging bag production line, including a film blowing machine 1, a printing machine 2, a cutting machine 3 and a conveyor 4, and also includes a transfer mechanism, a cooling mechanism and a robot arm 5. Compared with the packaging bag production equipment in the prior art, the present invention organically combines multiple independent devices through a conveying roller 102 to form a complete production line, and at the same time, the cut packaging bags are transferred by the robot arm 5. In the process of the conveying roller 102 conveying the packaging bags, the chiller 201 conveys cold water to the inside of the conveying roller 102 to cool the packaging bags. At the same time, the fan 402 performs air cooling and dust removal protection on the packaging bags. The packaging bags are leveled and tensioned by the pressing roller 704 and the tensioning roller to ensure the production quality of the packaging bags.

[0063] The film blowing machine 1 adds dry plastic particles into the lower hopper, and the particles enter the screw from the hopper by their own weight. When the particles come into contact with the bevel of the thread, the rotating bevel surface generates a thrust perpendicular to the bevel surface on the plastic, pushing the plastic particles forward. During the pushing process, due to the friction between the plastic and the screw, the plastic and the barrel, and the collision and friction between the particles, and also due to the external heating of the barrel, the molten plastic is gradually melted. The molten plastic is filtered through the machine head to remove impurities and comes out from the die mouth of the die head.
