Description

Technical Field

[0001] The utility model relates to the technical field of film production, in particular to a film blowing device suitable for fully biodegradable plastics. Background Art

[0002] Fully biodegradable plastic is a type of plastic synthesized from natural polymers or materials modified from natural polymers. It can be completely decomposed by microorganisms in the natural environment and eventually converted into water, carbon dioxide or other harmless substances. When using fully biodegradable plastics to produce films, film blowing equipment is required.

[0003] After searching, the announcement number is CN219523014U, and the name is a film blowing machine, including a bottom plate. Through research and analysis, it is found that although it can suppress the advantages of films of different thicknesses, it still has the following disadvantages to a certain extent.

[0004] For example, because the blown film is hot during use, there is no function to quickly cool the blown film, so the film cannot be quickly solidified, which easily causes stretching deformation, affects the quality of the film, and easily leads to dust absorption. Moreover, when the film is rolled up, there is no function to cut the film. Therefore, after the rolling is completed, the staff needs to cut it, which affects the shearing quality. In order to solve the above technical problems, we have designed a film blowing equipment suitable for fully biodegradable plastics. Utility Model Content

[0005] The purpose of the utility model is to provide a film blowing equipment suitable for fully biodegradable plastics, which has the advantages of quickly cooling the blown film and being able to shear the film, thereby solving the problems of not being able to quickly cool the blown film and not being able to shear the film.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The utility model cooperates with a fan, a long plate, an air blowing pipe, a mesh cover, a static eliminator, an air outlet head and an air blowing ring, and has the advantage of quickly cooling the blown film. The blown film first passes through the static eliminator to eliminate static electricity on the film surface, making it easier for dust to fall off, ensuring that the film surface is not easily adsorbed by dust. The air is transported into the air blowing ring through the fan and the air blowing pipe and blown out by the air outlet head, thereby quickly cooling the blown film.

By setting the static eliminator 705, static electricity on the surface of the blown film can be eliminated, so that dust on the surface of the film can fall off more easily and is not easily absorbed by dust;

[0024] See also Figure 1 and Figure 4 The tops of the long plates 702 on the front and rear sides are connected to the connecting plates 18 by bolts.

The winding roller 15 is driven by the driving motor 6 to rotate and rewind the film. When rewinding, the blown film first passes through the static eliminator 705 to eliminate the static electricity on the surface. At the same time, the fan 701 is running, and the film is blown out through the blowing pipe. 703 transports air into the blowing ring 707, and the air outlet head 706 blows out to quickly cool the surface of the film.

At the same time, the film is extruded and formed when it passes through the extrusion roller 12. After the film is rolled up, the drive motor 6 stops, and the electric telescopic rod 502 extends to push the movable frame 504 down, allowing the lower pressure roller 505 to descend to press the film. At the same time, the cutter 503 contacts the surface of the film to cut it, which facilitates the cutting of the film and improves the flatness of the cutting.
