[0030] As Figure 1-7As shown in the figure, a crushing device based on plastic particles of the present utility model includes a feeding box 1. A crushing chamber 3 is provided on one side of the feeding box 1 and is connected to it. A feeding port 2 is provided on the upper surface of the feeding box 1. A through hole 10 is provided on the side of the feeding box 1 connected to the crushing chamber 3, and the bottom inner wall of the feeding box 1 is set as an inclined surface 11. The plastics to be broken are put into the feeding box 1 through the feeding port 2. Under the action of the inclined surface 11 and the through hole 10, the plastics enter the crushing chamber 3 for crushing. A speed reducer 5 is provided on one side of the crushing chamber 3, and a motor 4 is provided on one side of the speed reducer 5. A first support frame 6 is provided at the bottom of the feeding box 1, and a second support frame 7 is provided at the bottom of the speed reducer 5. The side wall of the second support frame 7 is fixedly connected to the motor 4 through a motor bracket. An annular cavity 12 is provided in the inner cavity of the crushing chamber 3. An annular die 9 is fixedly installed inside the annular cavity 12. There is a gap between the outer side wall of the annular die 9 and the inner wall of the annular cavity 12. An outlet 8 is provided on one side of the bottom of the crushing chamber 3. The plastics entering the crushing chamber 3 will be inside the annular die 9 and are broken into granular form by the continuous rotation of three crushing rollers 16. The granules will enter the outside of the annular die 9 through the annular die 9 and be in the gap between the annular cavity 12 and the annular die 9, and will be discharged through the outlet 8 for centralized collection. The surface of the annular die 9 is provided with a plurality of uniformly and orderly distributed round holes, and the width of the annular die 9 coincides with the thickness of the annular cavity 12. Through the round holes provided on the annular die 9, the crushed qualified granules will enter the gap between the annular die 9 and the annular cavity 12 through the round holes, and the unqualified granules will continue to be in the crushing chamber 3 for continuous crushing.

[0031] A rolling crushing assembly is arranged inside the annular die 9. The rolling crushing assembly includes two relatively distributed first triangular plates 14 and second triangular plates 15. A rotating shaft 13 is fixedly connected between the middle parts of the first triangular plate 14 and the second triangular plate 15. And the motor 4 is connected to the rotating shaft 13 through a speed reducer 5. Crushing rollers 16 with adjustable distances from the inner wall of the annular die 9 are arranged between the three corners of the first triangular plate 14 and the second triangular plate 15. A connecting shaft 17 is rotatably connected between the first triangular plate 14 and the second triangular plate 15. And the connecting shaft 17 is connected to the eccentric part of the crushing roller 16. The end of the connecting shaft 17 extends to the outside of the second triangular plate 15 and is sleeved with an adjusting plate 18 in a fan shape. An arc-shaped adjusting opening 19 is arranged on the surface of the adjusting plate 18. Three orderly distributed fixing holes 20 located on the path of the adjusting opening 19 are arranged on the surface of the second triangular plate 15. The adjusting opening 19 and the fixing hole 20 are fixedly connected by bolts. The adjusting opening 19 and the connecting shaft 17 are concentric. When it is necessary to adjust the distance between the crushing roller 16 and the inner wall of the annular die 9, loosen the bolts on the adjusting opening 19 and the fixing hole 20. At this time, the adjusting plate 18 can be rotated around the axis of the connecting shaft 17. At this time, the connecting shaft 17 drives the crushing roller 16 to rotate. Since the connecting shaft 17 is connected to the eccentric part of the crushing roller 16, during the rotation of the connecting shaft 17, the distance between the crushing roller 16 and the inner wall of the annular die 9 will change, so as to facilitate the adjustment of the crushing thickness, with strong flexibility and greatly improved practicability.
