[0022] like Figure 1-4 As shown, the outer surface of one of the pulleys 1 4 is transmission-connected with a transmission belt 2 14, the inner surface of the transmission belt 2 14 is transmission-connected with a pulley 2 15, the inner surface of the pulley 2 15 is fixedly mounted with a rotating shaft 2 16, the outer surface of the rotating shaft 2 16 is fixedly mounted with two cams 17, the outer surface of the housing 2 is fixedly connected with a plurality of spring pieces 18, the bottom of the plurality of spring pieces 18 is fixedly connected with a screening block 19, which avoids the situation where the product is too large, improves the quality of the product, and will not affect the subsequent material grading, mixing uniformity, and the performance and quality consistency of the final product.

[0023] like Figure 1-4As shown, the support plate 20 is fixedly connected to the outer surface of the housing 2 , and the support plate 20 can support the motor 6 and provide a good working environment for the motor 6 .

[0024] like Figure 1-4 As shown, the second rotating shaft 16 is movably embedded in the inner surface of the support frame 1, and the second rotating shaft 16 can transmit the power of the second pulley 15 to the cam 17 to make the cam 17 rotate.

[0025] Working principle: This equipment is a crushing device for preparing hard carbon negative electrode materials. When in use, the raw materials are poured into the shell 2 on the support frame 1, and then the motor 6 on the support plate 20 is started. The motor 6 drives one of the rotating shafts 3 to rotate through the output shaft. One of the rotating shafts 3 is matched with a pulley 4 and a transmission belt 5 to make multiple rotating shafts 3 rotate synchronously. The multiple rotating shafts 3 drive multiple square blocks 7 to rotate. The multiple square blocks 7 indirectly drive multiple working plates 11 to drive multiple crushing wheels 12 to rotate through multiple unit blocks 8. The multiple crushing wheels 12 crush the raw materials. When one of the crushing wheels 12 is damaged, the square block 7 is removed from the rotating shaft 3, and then the unit block 8 is removed from the square block 7. Then the damaged crushing wheel 12 is pushed, and the damaged crushing wheel 12 is The crushing wheel 12 moves the working plate 11 in the slot 10 and pushes the fastening block 13 out of the slot 9, and then moves the crushing wheel 12 in the opposite direction, so that the damaged crushing wheel 12 can be easily removed. At the same time, one of the pulleys 14 drives the pulley 15 to rotate through the transmission belt 14, and the pulley 15 drives the two cams 17 to rotate through the rotating shaft 16. As the two cams 17 rotate, the screening block 19 will be squeezed. At this time, multiple spring pieces 18 will bend and gain elastic potential energy. When the cam 17 no longer squeezes the screening block 19, the spring pieces 18 will release the elastic potential energy, so that the screening block 19 moves to the initial position, thereby causing the screening block 19 to vibrate, and the products are screened. Employees can continue to crush larger products.
