[0002] At present, packaging bags are widely used in our daily life and work because they are convenient to use and carry. Among various packaging bags, plastic bags are particularly widely used because of their unique sealing and lightness. Plastic packaging bags include polyethylene plastic bags, polypropylene plastic bags and polyvinyl chloride plastic bags, which can not only protect products and facilitate storage and transportation, but also promote sales and beautify products. When producing plastic packaging bags, an extruder is used to melt plastic particles, and then a film blowing molding mechanism is used to blow out the molten material evenly. Since the material temperature is high when it is blown out, it is difficult to form a film quickly, which affects the work efficiency of the molten material film making. It is necessary to use an air wind ring on the outside of the film to evenly blow and cool the film, so that the temperature of the material drops quickly and evenly to ensure that the material can form a film quickly.
