Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag processing, in particular to a plastic bag film blowing rapid cooling device. Background Art

[0002] Food packaging bags are generally made of polyethylene and polypropylene, and synthetic resins are almost always used for packaging among plastics. However, when the existing cooling device uses air cooling for cooling, dust accumulates inside after long-term use, and the dust is carried when it is blown out again, resulting in a poor production environment.

[0003] In the related technology, such as the Chinese patent with application number: "202121836199.3", its name is: "A cooling device for a plastic bag film blowing machine". Through the cooperation of the hollow rod and the holes, and the cooperation of the filter screen and the filter element, the wind in the hollow rod is blown out through the holes, and finally blown to the plastic film on the rotating rod through the filter element and the filter screen. The filter screen and the filter element achieve the purpose of filtering the air and keep the air near the plastic film clean. Through the cooperation of the slider and the slide groove, and the cooperation of the baffle and the limiting structure, the wind blown out at the filter screen can quickly cool down the plastic film. At the same time, the position of the baffle can be adjusted. The slider on the baffle can move inside the slide groove, and the position of the baffle is fixed by the limiting structure. The position of the air outlet is adjusted, the exposed filter area is large, and the blown wind is relatively scattered. On the contrary, the blown wind is more concentrated in one position, which can be adjusted according to actual usage conditions. It has strong flexibility and is conducive to promotion.
