Description

Technical Field

[0001] This utility model relates to mixers, and more particularly, to a high-efficiency mixer for the production of plastic masterbatch. Background Technology

[0002] The full name of color masterbatch is color masterbatch, which is a new type of special coloring granules for polymer materials. It is mainly used in plastic granules. Color masterbatch is composed of pigments, dyes or color powders mixed with carriers and additives. Generally, color masterbatch is made by mixing pigments with plastic raw materials, heating the mixture and sending it into an extruder to form color masterbatch. The color masterbatch is then sent into an injection molding machine to produce colored plastics.

[0003] Currently, Chinese patent CN216831688U discloses a structure for a color masterbatch mixer for plastic bottle production, including a mixing box. A feed pipe and a fixed column are fixedly connected to the upper surface of the mixing box, and a discharge pipe is fixedly connected to the periphery of the mixing box. A stirring rod is installed inside the mixing box to stir the materials.

[0004] The aforementioned patents still have shortcomings. The production of color masterbatch requires a strict pigment ratio; otherwise, the produced color masterbatch is prone to color differences. The aforementioned mixers require operators to accurately adjust the ratio of pigments and plastic raw materials, which places high demands on operators and can easily affect production efficiency.
