Description

Technical Field

[0001] The utility model relates to a mixer, in particular to a raw material mixer for the production of masterbatch. Background Technique

[0002] Masterbatch is a kind of high-concentration colored particles, which is a mixture of high-concentration colors prepared from resin and pigments or dyes. When processing masterbatch, the resin and pigments need to be fully mixed in a certain proportion, and then formed through a series of processes such as cooling and granulation.

[0003] When producing masterbatch, a variety of raw materials need to be mixed together. The existing premixing devices generally use stirring rods to stir directly in the stirring tank. The centrifugal force generated when the stirring rods stir easily causes the raw materials to be in a "water vortex" state, thereby reducing the contact between the raw materials, reducing the mixing efficiency and effect of the raw materials, and it is easy to produce dead corners in the stirring tank when using the stirring rods to stir, resulting in uneven mixing of the raw materials. For example, the application with the application number CN202220278636.2. Content of the Utility Model

[0026] The stirring and rotating mechanism is used to drive the mixing barrel 2 to rotate, so as to rotate and mix the masterbatch raw materials. At the same time, a number of stirring convex columns 35 are used to disperse the raw materials during the rotating stirring, so that the raw materials are quickly and evenly mixed, improving the mixing efficiency.
