[0042] See also Figure 1 , Figures 6 to 11 In one embodiment of the present invention, it also includes a conveying part 3, which includes a rotating shaft 31, a conveying screw 32 and a third transmission gear 33.

[0043] In the embodiment of the present invention, the rotating first transmission gear 16 drives the conveying screw 32 to rotate through the third transmission gear 33, and the rotating conveying screw 32 automatically conveys the small-granular plastic particles to the designated position.

[0044] Working principle: First, the plastic particles in the storage box are transported to the annular housing 11 through the feed pipe 19, and then the driving unit 23 controls the central tube 24 and the first transmission gear 16 to rotate through the second transmission gear 25. Fig. 9 The ring 21, the inclined plate 22, the blanking port 26, and the dynamic material distribution component 4 rotate clockwise around the central tube 24. The fourth transmission gear 43 in the dynamic material distribution component 4 controls the small-diameter mesh belt 41 to slide between the three rotating rollers 42 by means of transmission connection with the gear ring 15. At the same time, the rotating first transmission gear 16 drives the conveying screw 32 to rotate through the third transmission gear 33. Based on the above technical principles, the following technical effects can be achieved:

[0045] (1) When the plastic particles fall on the surface of the small-diameter mesh belt 4, since the small-diameter mesh belt 4 can rotate clockwise with the central tube 24 as the axis and slide between the three rotating rollers 42, the plastic particles can roll evenly on one side of the surface of the small-diameter mesh belt 41, so that the small-particle plastic particles can efficiently enter between the two inclined plates 22, and then enter the small-particle material conveying pipeline 12 through the blanking port 26 and the receiving port 121. It should be noted that after the rotating mechanism 2 rotates 120 degrees clockwise, the driving unit 23 controls the rotating mechanism 2 to rotate 60 degrees counterclockwise, and then continues to rotate clockwise to the initial position. On the one hand, it ensures that the small-particle plastic particles can completely enter between the two inclined plates 22, and on the other hand, it ensures that the small-particle plastic particles between the two inclined plates 22 can completely enter the small-particle material conveying pipeline 12 through the blanking port 26 and the receiving port 121. Finally, the rotating conveying screw 32 automatically conveys the small-particle plastic particles to the specified position;

[0046] (2) When the remaining plastic particles pass through the medium-diameter dividing hole 111 clockwise, the medium-particle plastic particles enter the medium-particle material cavity 131 through the medium-diameter dividing hole 111; when the remaining plastic particles pass through the large-diameter dividing hole 112 clockwise, the large-particle plastic particles enter the large-particle material cavity 132 through the large-diameter dividing hole 112; finally, the medium-particle plastic particles and the large-particle plastic particles are transported to the designated position through the medium-particle material conveying pipe 17 and the large-particle material conveying pipe 18, respectively.

[0047] To summarize, the present application utilizes a structural design that combines a shell mechanism 1, a rotating mechanism 2, and a dynamic material distribution component 4. On the one hand, the present application can utilize a small-diameter mesh belt 41 that rotates clockwise with the center tube 24 as the axis and slides between three rotating rollers 42 to enable small-particle plastic particles to efficiently enter between the two inclined plates 22, and then enter the small-particle material conveying pipe 12 through the drop port 26 and the receiving port 121, and utilize the first transmission gear 16 and the third transmission gear 33 to drive the conveying screw 32 to convey the small-particle plastic particles to the specified position. On the other hand, the present application utilizes the rotating mechanism 2 and the small-diameter mesh belt 41 to drive the remaining plastic particles to pass through the medium-diameter material distribution holes 111 and the large-diameter material distribution holes 112 in turn, so as to control the medium-particle plastic particles and the large-particle plastic particles to be conveyed to the specified position through the medium-particle material conveying pipe 17 and the large-particle material conveying pipe 18 respectively. The present application has the characteristics of ingenious structural coordination, good material distribution effect, and high working efficiency.
