[0002] Mixing raw materials is an important step in the injection molding process. It ensures that the plastic raw materials are evenly mixed before injection molding, thereby improving the quality of the molded product. In injection molding, different mixing techniques may be used, such as using an agitator or mixer to mix colorants with pure materials, or using masterbatches, colored granules, and liquid pigments for coloring. Therefore, a raw material mixing device is needed.

[0003] When dust is mixed in the injection molding raw materials, it may cause spots, unevenness or impurities on the product surface, affecting the appearance of the product. The mixing of dust may weaken the strength of the material, so it is necessary to remove the dust in the raw materials before injection molding. The existing mixing device is difficult to remove the dust on the surface of the injection molding raw materials, which will reduce the quality of the product. Utility Model Content
