In conjunction with the gas sprayed by the telescopic airbag 603, the powder between the raw materials that have not been completely ground can be discharged from the discharge bin 502.

[0026] In this embodiment, Figures 1 to 10 As shown, the grinding assembly 7 includes a locking block 701, a grinding block 702 and an abutment bar 703. The outer wall of the locking block 701 is movably plugged into the inner wall of the locking groove, and the bottom of the locking block 701 is fixedly connected to the top of the grinding block 702. A rolling groove is provided on the inner wall of the grinding block 702, and the inner wall of the rolling groove is fixedly connected to one side of the abutment bar 703.

[0027] In this embodiment, Figures 1 to 10As shown, the grinding head assembly 8 includes a grinding rod 801, a return spring 802 and a grinding head 803.

When the pushing block 602 moves downward, it pushes the grinding rod 801 to extend out from the inside of the grinding block 702, thereby pushing the grinding head 803 out from the inside of the grinding block 702 and abutting against the inner wall of the discharge bin 502. When the pushing block 602 moves downward and separates from the grinding rod 801, the grinding rod 801 drives the grinding head 803 to retract into the grinding block 702 under the telescopic force of the reset spring 802, thereby vacating the gap between the grinding block 702 and the discharge bin 502, providing enough space for the raw materials above to fall.

[0028] In this embodiment, Figures 1 to 10 As shown, the inner top wall of the grinding block 702 is fixedly connected to the top of the telescopic airbag 603, and an air inlet valve and an air outlet valve are provided on the top of the grinding block 702, and the bottom ends of the air inlet valve and the air outlet valve are fixedly connected to the inner top wall of the telescopic airbag 603. When the grinding block 702 drives the telescopic airbag 603 to be pulled downward, air is inhaled and expanded through the air inlet valve to fill the interior of the grinding block 702. When the grinding block 702 drives the telescopic airbag 603 to be squeezed upward, air is exhausted through the air outlet valve, so that the powder that is not discharged in time after grinding is discharged from the screen 504 again into the collection bin 505, and at the same time, the powder blocked on the screen 504 will be cleared to avoid blockage of the screen 504.

[0029] The use method and advantages of the present invention: When the new hard carbon negative electrode material grinding machine is working, the working process is as follows: like Figures 1 to 10As shown, the raw material of the hard carbon negative electrode material is placed into the feed bin 401 from the feed pipe 402, and the drive motor 103 is started. The drive motor 103 drives the drive pipe 104 to rotate, and the drive pipe 104 directly drives the drive wheel 201 to rotate. The drive wheel 201 drives the drive wheel 203 to rotate through the transmission belt 202, and the drive wheel 203 drives the crushing rod 301 to rotate, and the crushing rod 301 drives the rotating disk 302 to rotate, and the rotating disk 302 drives the rotating rod 303 to revolve, and the rotating rod 303 drives the gear 306 to mesh with the toothed disk 307, so that the gear 306 drives the rotating rod 303 to rotate in the rotating disk 302, and the rotating rod 303 drives the crushing roller 304 to rotate, and the crushing roller 304 passes through the crushing hammer when rotating. 305 performs a crushing operation on the raw materials, and the raw materials crushed into small pieces enter the discharge bin 502 through the discharge pipe 403. The driving pipe 104 drives the linkage rod 601 to rotate when rotating. The linkage rod 601 moves downward under the force of the threaded engagement of the limit block 503. The linkage rod 601 pushes the push block 602 to move downward, and the push block 602 pushes the grinding rod 801 to extend outward. When the grinding rod 801 squeezes the return spring 802, the grinding head 803 extends out from the grinding block 702. When the linkage rod 601 abuts against the inner bottom wall of the grinding block 702, the grinding block 702 is pushed to continue to move downward, so that the engaging block 701 is disengaged from the limit block 503. The grinding block 702 starts to rotate and move downward. After the linkage rod 601 abuts against the inner bottom wall of the driving tube 104, the grinding head 803 also abuts against the inner side wall of the discharge bin 502. At this time, the linkage rod 601 disengages from the engagement with the limit block 503 and starts to rotate. At the same time, when the pushing block 602 moves downward in the grinding block 702, the flip wheel 605 on the outer wall of the flip rod 604 drives the flip rod 604 to rotate and move downward under the friction force with the abutment strip 703. Small pieces of raw materials are flipped by the flip plate 606 to the bottom of the discharge bin 502. When the pushing block 602 moves downward, it will pull the telescopic airbag 603 to start inhaling and expanding, filling the inside of the pushing block 602 to prevent the raw materials from entering the pushing block 602. 02, small pieces of raw materials are ground into powder by the grinding head 803 and then leak out from the screen 504 into the collecting bin 505. The driving motor 103 starts to move in the opposite direction after moving for a period of time. When the linkage rod 601 is threadedly connected to the limit block 503 again, the linkage rod 601 starts to rise in the opposite direction, and the flip plate 606 flips the uncompleted ground raw materials on the top downward, and the telescopic airbag 603 discharges the internal airflow, blowing the ground powder out of the discharge bin 502, thereby expanding the gap between the uncompleted ground raw materials. At the same time, the grinding head 803 shrinks again into the grinding block 702 under the telescopic force of the reset spring 802, providing enough space for the flip plate 606 to flip the upper raw materials to the bottom next time.
