[0002] Existing plastic products usually require the use of multiple different plastic particles at the same time due to different requirements for properties such as color, density and corrosiveness. Before hot-melting the mixed plastic particles, a plastic mixer is usually used to stir and mix the various plastic particles. The uniformity of the stirring will directly determine the quality of the finished product. Patent application number: CN201520583916.4 discloses a plastic particle mixer, including a stirring tank, on which a feed funnel and a discharge port are provided. The top of the stirring tank is provided with a stirring motor connected together. The stirring motor transmits power to a stirring screw in the stirring tank by rotation, and the stirring motor drives the stirring screw to rotate to stir the plastic particles.
