[0021] A variety of different resin pellets are poured into the mixing barrel 1 through the circular groove. The various pellets gather at the bottom of the mixing barrel 1. At this time, the first motor 2 drives the round rod 3 to rotate, and the round rod 3 drives the spiral block 6 to rotate in the circular barrel 5. The spiral block 6 wraps the pellets and moves the pellets upward, detaches from the upper end of the spiral block 6, and falls freely. At the same time, along with the rotation of the spiral block 6, the pellets are thrown away at a high place and dispersed everywhere, which is beneficial to improve the mixing effect of the resin pellets and avoid the accumulation of the same kind of pellets. After a period of time, the electric valve 8 is opened, and the mixed pellets flow out through the output pipe 7.

[0022] The upper surface of the mixing cylinder 1 is fixedly connected to multiple rotating cylinders 9, the number of which is the same as the circular through grooves, and the rotating cylinder 9 is communicated with the circular through grooves.
