[0023] Working principle:

[0024] In use, the adjusting device 4 is arranged to control the distance between the crushing rollers 3, the screw rod 42 is rotated by starting the servo motor 41, and then the rotating of the screw rod 42 is controlled, the clamping block 44 is moved under the driving of the screw thread of the screw rod 42, the limiting device 43 at the top of the screw rod 42 is determined in position at the top of the screw rod 42 through the connecting hole 433 and the anti-dropping groove 434, and can rotate around the axis of the screw rod 42, so as to limit the clamping block 44, and the limiting block 431 slides on the limiting groove 45 through the sliding block 432, and the clamping block 44 body slides on the base 1, so as to limit the moving direction of the clamping block 44, since the adjusting device 4 is arranged at both ends of the crushing roller 3 at the same time, and the clamping block 44 moves synchronously, the clamping block 44 clamps the crushing roller 3 and moves, so that the crushing roller 3 moves at both ends, the two crushing rollers 3 rotate in opposite directions through the direct current motor 7, the crushing roller 3 clamped by the clamping block 44 can approach or move away from the other crushing roller 3 rotating at a fixed position on the base 1 under the control of the adjusting device 4, and then the effect of adjusting the crushing gap is obtained, and the effect makes the crushing device adapt to plastic product raw materials of different sizes and hardnesses, for larger size or harder raw materials, the distance between the crushing rollers 3 can be appropriately increased to ensure smooth feeding and preliminary crushing, and for smaller size or softer raw materials, the distance is reduced to achieve more fine crushing effect, and then the flexibility and controllability of crushing are improved, the distance can be adjusted at any time according to production needs and product requirements, so as to achieve the best crushing particle size and quality, at the same time, unreasonable distance can be avoided to cause excessive wear or uneven stress, the equipment maintenance cost is reduced, and reasonable distance adjustment can reduce the jamming and failure in the crushing process, so that the crushing process is smoother, thereby the production speed is accelerated, and the stability of product quality is ensured.

[0025] The shaking device 5 is arranged to shake the rotating plate 2 and accelerate the plastic product raw materials to move to the position of the crushing roller 3. In use, the staff on the side of the crushing device holds the rotating handle 54 and moves the connecting rod 53, so that the extension rod 52 rotates, and then the cam bar 51 rotates, the cam bar 51 rotates to lift the rotating plate 2 through the protruding part, and the cam bar 51 will lose the lifting effect on the rotating plate 2 for part of the time in the rotating process. When the rotating plate 2 loses the lifting force, the rotating plate 2 falls due to its own gravity and is blocked by the limiting strip 6, and finally the rotating plate 2 shakes, which can effectively break the adhesion and accumulation between the raw materials. Since the plastic product raw materials may be adhered to each other or accumulated together during storage and transportation, the shaking action can make them dispersed, move more uniformly to the position of the crushing roller 3, and then improve the smoothness of the feeding, and secondly accelerate the feeding speed. Through the power generated by the shaking, the raw materials are pushed to reach the crushing roller 3 faster, so as to improve the efficiency of the whole crushing process and help to reduce the occurrence of feeding blockage. The uniformly dispersed and fast moving raw materials are not easy to form blockage at the feeding port, so as to ensure the continuity of the crushing work and reduce the downtime and maintenance time caused by blockage.
