[0002] In the process of plastic processing, the plastic mixture needs to be mixed and mixed. The mixed plastic raw materials are melted by a melting machine and finally made into plastic. In the past, a mixer was generally used to mix and stir the plastic.

[0003] Plastic raw materials are generally mixed with plastic particles and various pigment powders. When mixing, first fill a large amount of plastic particles into the mixing barrel, and then fill a variety of powders into the mixing barrel in a certain proportion and mix with the plastic particles;
