PE Double Color Strip Film Blowing Machine

The SJ40×2,45×2 PE double color strip film blowing machine developed by Huawei Machinery, as a representative equipment in the color stripe film blowing machine, adopts a two-sided three-tool screw barrel and a die head combination design, matched with two types of masterbatch configurations. It can directly blow produce various specifications of color stripe vest bags (procurement bags) without the need for printing, presenting colored text. It has the advantages of bright colors, reasonable structure, leading technology, smooth winding, high production and efficiency. Compared with the black and white film blowing machine that focuses on specific color film production, although the emphasis is different, it still demonstrates the precision of professional equipment.Specifically, as follows:

● 1.The whole machine is composed of a set of rotating host, two-sided three-tool barrel and a die head. The feeding is completed through the two-sided three-tool barrel feeding, and the single die head is synchronously extruded. Combined with a traction winding device, it can significantly improve the production of color strip film. This design allows it to achieve a much higher efficiency in mass production of color strip film than ordinary equipment.

● 2.Screw, barrel using 38CMoaAl, after nitriding treatment and precision processing, high hardness, high resistance, corrosion resistance, durable, just like the high standard requirements for core components of black and white film blowing machines, ensuring long-term efficient production.

● 3.The surface of the die is plated with hard chromium and adopts a spiral mandrel type structure, which ensures uniform distribution of extruded molten material and excellent smoothness of the blown film; The air cooling device is designed in a maze style, with uniform air output, effectively ensuring the quality of film forming.

● 4.The winding device adopts pressure friction winding and central winding, adopts torque motor adjustment and the rolled film is flat and standardized, and the replacement operation is convenient, further improving the continuity and convenience of production.
