A stirring motor 8 is fixedly connected to the outside, and the right side of the stirring shaft 6 is fixedly connected to the output end of the stirring motor 8. Both sides of the stirring shaft 6 are rotatably connected to the inner walls of the first frame 13 and the second frame 14 through bearings 5. The outer wall of the stirring shaft 6 is fixedly connected with a stirring blade 9. The stirring blade 9 adopts a turbine folding blade stirring structure, and three stirring blades 9 are evenly spaced. A transmission assembly 15 that can drive the mixing barrel 1 to rotate is provided between the mixing barrel 1 and the second frame 14. The transmission assembly 15 includes a driving motor 151 fixedly connected to the top of the second frame 14 and a driven ring 153 fixedly connected to the periphery of the mixing barrel 1. The output end of the driving motor 151 is movably connected to a driving wheel 152, and the driving wheel 152 and the driven ring 153 are connected by a transmission belt 154. The mixing barrel 1 and the stirring motor 8 drive the counterclockwise rotating stirring shaft 6 to cooperate with the guide plate 2 provided on the inner wall of the mixing barrel 1 to fully mix the materials inside the mixing barrel 1.

[0032] Reference Figure 1 and Figure 2 A positioning assembly 16 is provided between the second frame 14 and the mixing barrel 1. The positioning assembly 16 includes a mounting frame 161, a photoelectric positioning sensor 162, a lower material level photoelectric locator 163 and an upper material level photoelectric locator 164.

The stirring motor 8 drives the stirring shaft 6 to rotate counterclockwise to cooperate with the mixing barrel 1 to fully stir and mix the materials inside the mixing barrel 1. After the mixing is completed, the photoelectric positioning sensor 162 of the positioning component 16 senses the upper and lower material position photoelectric positioners 163 of the mixing barrel 1. Under the drive of the transmission component 15, the inlet and outlet 10 of the mixing barrel 1 is driven to rotate to the lower material position. The stirring motor 8 drives the stirring blade 9 on the stirring shaft 6 to rotate, and gradually pushes the mixed granulated plastic particles out from the rotation point of the stirring blade 9 for material removal.
