Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of garbage bag production and processing, in particular to a film blowing machine for garbage bag processing. Background Art
[0002] Garbage bags, as the name implies, are bags for garbage. Garbage bags are mainly made of plastic. Plastic garbage bags are made of plastic film and are widely used in all aspects of daily life and production. The raw material of plastic garbage bags is plastic, which is a kind of resin. Resin refers to a polymer compound that has not been mixed with various additives. In addition to the polymers we often talk about, the constituent materials of plastics also include various plastic additives, such as antioxidants, light and heat stabilizers, reinforcing agents and fillers, to improve the processing and use performance of plastics. Film blowing machines are required in the production and processing of garbage bags.
[0003] Common film blowing machines for garbage bag processing are usually composed of extruder systems, die head systems, film blowing chambers, inflation steam generators, compressed air pumps, winding devices, and cutting devices. When the mold temperature reaches a suitable temperature, the raw materials are put into the extruder, the raw materials are melted under high temperature and high pressure, and pass through the film blowing chamber and the inflation steam generator to form a film, so that air enters the film, the film enters the winding device for winding, and the cutting device is used to cut it off. This is the common structure and use of film blowing machines for garbage bag processing. Traditional film blowing machines for garbage bag processing are prone to cause the garbage bags to deviate when there is external wind, affecting the collection of garbage bags, making the collected garbage bags uneven and affecting subsequent sales. For example, patent number CN218256753U is an automatic film blowing machine for pet garbage bag processing, which is equipped with a connecting plate and a first limiting wheel. When the hydraulic rod drives the second limiting wheel and the first limiting wheel, the garbage bag is further limited to prevent the garbage bag from being deviated by the external wind during the film blowing process. However, this method can only limit the center of the film surface, but not the side of the film, because there are only two sets of upper and lower limiting wheels in a single direction. As a result, the side of the film is unstable under the influence of external wind, and may even be torn or damaged. Therefore, a film blowing machine for garbage bag processing is proposed.
