Description

Technical Field

[0001] This utility model relates to the field of masterbatch processing, and in particular to a screening device for modified color masterbatch. Background Technology

[0002] Masterbatch, also known as plastic masterbatch, is a plastic processing aid developed in the 1980s. It consists of a large amount of chemical additives, carrier resin, and dispersants. Masterbatch is an aggregate obtained by uniformly loading a large amount of pigment into resin. In plastic processing, masterbatch refers to the granular material produced by mixing various additives, fillers, and a small amount of carrier resin for ease of operation during the molding process. This mixture is then metered, mixed, melted, extruded, and pelletized using equipment such as extruders. Masterbatch is composed of carrier resin, various fillers, and various additives. The amount of additives or fillers in masterbatch is several to ten times higher than the amount required in the actual plastic product. During molding, the ratio of masterbatch to matrix resin must be adjusted according to the content of relevant components in the masterbatch and the amount required in the actual product. Masterbatch can generally be divided into ordinary filler masterbatch and functional masterbatch, such as color masterbatch and anti-fogging masterbatch.

[0003] However, modified masterbatches come in different sizes during production. To facilitate subsequent processing, it is necessary to separate and screen the modified masterbatches of different sizes. Traditional masterbatch screening equipment, such as the technical solution disclosed in the patent application number CN202221996673.3 entitled "Plastic Masterbatch Screening Machine," is not convenient for separating and collecting the screened masterbatches.
