The U-shaped support frame 12 can be used to ensure the stability of the movable plate 6 when it moves forward and backward.

[0031] Reference Figure 4 As shown, in order to achieve the purpose of crushing the rubber in the processing frame 4, the movable plate 6 is located in the processing frame 4 and is fixedly connected to a crushing assembly at one end. The crushing assembly includes a mounting plate 13 fixedly connected to the end of the movable plate 6. The outer wall of the mounting plate 13 is fixedly connected to a plurality of equidistant crushing knives 14. The two groups of crushing knives 14 are staggered to achieve a better crushing effect.
