As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, a plastic film blowing machine 10 includes a feeding bin 100, a hot-melt stirring device 200, a film blowing device 300, and a shrinking and flattening device 400.

Thus, it should be noted that the feeding bin 100 plays a role of feeding; the hot melting stirring device 200 is used for stirring and hot melting the raw materials; the film blowing device 300 is used for blowing a film on the hot-melt raw material; the shrink flattening device 400 is used for shrinking and flattening the hot-melt raw materials.

Referring to fig. 1, the hot-melting stirring apparatus 200 includes a tube 210, a servo motor, a stirring rod, and a hot-melting module, the tube 210 is communicated with the feeding bin 100, the servo motor is disposed in the tube 210, the stirring rod is connected to a driving shaft of the servo motor, and the hot-melting module is disposed on an inner side wall of the tube.

So, it should be noted that, when hot melt stirring device 200 started work, the raw materials entered into to body 210 inside from pan feeding storehouse 100, and servo motor output power rotated the puddler, stirred solid-state raw materials, and meanwhile, the hot melt module produced heat hot melt raw materials.

Referring to fig. 1, the film blowing apparatus 300 includes a blower disposed in the tube 210, and a film blowing head 310, the film blowing head 310 being in communication with the tube 210, the film blowing head 310 being provided with a cooling ring 311.
