Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch production devices, in particular to a pelletizing device for masterbatch production. Background Art

[0002] Masterbatch is a color regulator widely used in the production process of plastic products. They are usually composed of pigments, additives and resins, which can provide the desired color and appearance characteristics for plastic products. In the plastics industry, masterbatches are widely used in automotive parts, household appliances, packaging materials and other fields. Masterbatch bars usually exist in the form of strips. In order to better mix with plastic materials during the production process, the masterbatch bars need to be cut into small particles so that they can be better mixed with plastic particles. Therefore, pelletizing equipment plays a vital role in the production process of masterbatch.

[0003] Traditional masterbatch pelletizing equipment has some defects, which may lead to poor cutting results and even affect the quality and appearance of the final plastic products. These defects include but are not limited to:

[0004] Uneven cutting: In traditional equipment, masterbatch strips are often mixed together when passing through the cutting channel. Due to the imprecise cutting process, it is easy to cause particles of different sizes, thus affecting the color uniformity and appearance quality of plastic products.

[0005] Low production efficiency: Traditional equipment may have problems such as complex operation and difficult adjustment, which will affect production efficiency and increase production costs. Utility Model Content
