Description

Technical Field

[0001] The utility model belongs to the technical field of plastic processing equipment, in particular to a cooling device for preparing masterbatch for uniformly coloring plastic products. Background Art

[0002] Plastic masterbatch is a material used to color plastic products. It is usually a granular substance composed of pigments, carrier resins and auxiliary additives. Masterbatch can provide a variety of colors and effects, such as transparent, translucent, matte or metallic luster, etc. They play a key role in the plastic processing industry and can adjust the color, appearance and texture of plastic products according to needs. After the molten mixture is extruded into granular materials through equipment such as extruders or granulators, it needs to be cooled by cooling equipment to make it solidify quickly and ensure that the temperature of the masterbatch drops below room temperature to avoid adhesion or agglomeration during packaging and storage.

[0003] However, in the prior art, plastic masterbatch cooling methods are mostly performed by spraying cooling water and air cooling. When spraying cooling water, the liquid will adhere to the surface of the masterbatch, which is easy to affect the subsequent pigment coloring. When air cooling is used for cooling, the accumulation of masterbatch will also make the heat dissipation insufficient. For this reason, we provide a masterbatch preparation cooling device for uniformly coloring plastic products to solve the above problems. Utility Model Content

The device solves the problem in the prior art of plastic masterbatch cooling equipment that, when dissipating heat through water cooling, liquid adheres to the surface of the masterbatch and affects the subsequent pigment coloring by coordinating the ventilation component and the refrigeration component.
