[0040] The working principle and use process of this utility model:
[0041] When the operator needs to crush the plastic, first start the third motor 27. The operation of the third motor 27 will cause the rotating rod 28 to rotate. At this time, the rotating rod 28 will cause the rotating plate 29 to rotate at the same time. At this time, the rotating plate 29 will cause the push-pull plate 30 to rotate and pull the baffle 25. At this time, the plastic inside the discharge chute 24 will automatically enter the inside of the casing 15. At this time, the operator starts the second motor 18. The operation of the second motor 18 will cause the rotating shaft 19 to rotate with the first gear 20 at the same time. At this time, the first gear 20 will cause the second gear 22 to rotate with the rotating rod 21 at the same time. At this time, the rotating shaft 19 and the rotating rod 21 will simultaneously cause the crushing roller 23 to rotate and crush the plastic. The crushed plastic will enter the top of the vibration plate 5 through the guiding effect of the inclined plate 16.
[0042] At this time, the operator starts the first motor 11. The operation of the first motor 11 will cause the rotating shaft 12 to rotate with the rotating block 13. Since the shape of the rotating block 13 is elliptical, the rotating block 13 will cause the lifting block 10 to move upward with the vibration plate 5. As the rotating block 13 rotates, the spring 8 will move the vibration plate 5 downward due to the recovery effect of the elastic force. At this time, the vibration plate 5 will vibrate and screen the crushed plastic. At this time, the plastic will fall into the collection box 3. The operator can take out the large particles of plastic on the top of the vibration plate 5 for secondary crushing. At this time, the operator pulls the collection box 3, and the collection box 3 will move forward smoothly under the limiting action of the fixed plate 2 and the limit block 14. At this time, the plastic inside the collection box 3 can be taken out.
