A plurality of stirring blades 8 are provided, and a plurality of stirring blades 8 are evenly spaced on the outer wall of the stirring rod 23, which can fully and comprehensively stir the plastic particles. The mounting seat 22 is provided with two groups, and the two groups of mounting seats 22 are symmetrically distributed about the central axis of the collecting box 17. The cross-section of the mounting seat 22 is larger than the cross-section of the dust collecting net box 21, and a locking structure is formed between the mounting seat 22 and the dust collecting net box 21, which is convenient for disassembly and assembly of the dust collecting net box 21, and then the dust and impurities collected therein are cleaned. The fan 20 is provided with two groups, and the two groups of fans 20 are symmetrically distributed about the central axis of the collecting box 17, which has a better adsorption effect on dust and impurities.

[0024] Specifically, if Figure 1 and Figure 3 As shown, the second servo motor 11 is started to drive the stirring blade 8 to rotate through the stirring rod 23 to stir the plastic particles falling into the feed hopper 9. During the stirring process, the light dust and impurities adhering to the surface of the plastic particles will fly up.
