Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch production equipment, and more specifically to a particle extruder used for masterbatch granulation and molding. Background Art

[0002] Masterbatch is a new type of colorant specially used for polymer materials, also known as pigment preparation. Masterbatch is mainly used in plastics. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading an extraordinary amount of pigment into the resin. The ink method is a commonly used masterbatch processing method. The specific steps of the ink method include: coating a low-molecular protective layer on the surface of the pigment through three-roll grinding, then mixing the ground fine color paste with the carrier resin, plasticizing it through a two-roll plasticator, and finally granulating it through a pellet extruder.

[0003] Insufficients of existing technology: In order to ensure that the masterbatch raw materials have a certain fluidity during use, a heating device is installed inside the pellet extruder to heat the masterbatch raw materials during operation. However, the heating devices of existing pellet extruders are mostly installed inside the casing, which may cause uneven heat distribution during use, affecting the quality of subsequent finished products. Existing pellet extruders mostly use a spiral to drive the masterbatch raw materials to flow in the equipment and finally extrude them from the mesh plate and cut them. After extrusion, the masterbatch temperature is high and deformation is likely to occur. Utility Model Content
