The output end of the first motor 10 is connected to the driving wheel 7. A support frame 11 is fixedly connected to the top end of the main board 2. A feeding bin 12 is fixedly connected to the support frame 11. The feeding bin 12 is located above the sliding groove 5. Materials fall from the feeding bin 12 onto the main board 2. The first motor 10 is started to drive the driving wheel 7 to rotate. The driving wheel 7 drives the driving chain 8 to rotate. The driving chain 8 drives the pushing plate 9 to move. One end of the pushing plate 9 passes through the sliding groove 5 to push the materials, thereby pushing the materials towards the grinding bin 4, so as to achieve the purpose of automatic feeding, so that the pushing plate 9 always moves in the clockwise direction, so as to avoid pushing the materials in the reverse direction, so as to achieve the purpose of maintaining the working efficiency of the equipment.

[0029] Referring to Figure 2 and Figure 3, a support member 13 is fixedly connected between the pusher plate 9 and the transmission chain 8. The support member 13 is used to support the pusher plate 9, reducing the probability of the pusher plate 9 bending or deflecting when pushing the material, so as to achieve the purpose of improving the stability of the equipment.

[0030] Refer to Figure 1 , a guide rail 14 matching the sliding groove 5 is fixedly connected to the top end of the main board 2. One end of the guide rail 14 is connected to the grinding chamber 4. The guide rail 14 is used to guide the material, so that when the pusher plate 9 pushes the material, the material moves in a straight line, so that the material can smoothly enter the grinding chamber 4, so as to achieve the purpose of improving work efficiency.

[0031] Refer to Figures 1 - 4 , first grooves and second grooves are opened at both the left end and the right end of the feeding bin 12.

The driving wheel 7 drives the driving chain 8 to rotate. The driving chain 8 drives the pusher plate 9 to move. One end of the pusher plate 9 passes through the sliding groove 5 to push the material, thereby pushing the material towards the grinding bin 4, achieving the purpose of automatic feeding. In this way, the pusher plate 9 always moves in the clockwise direction, avoiding the situation of pushing the material in the opposite direction, and achieving the purpose of maintaining the working efficiency of the equipment. The support member 13 is used to support the pusher plate 9, reducing the probability of the pusher plate 9 bending or deflecting when pushing the material, thereby achieving the purpose of improving the stability of the equipment. The guide rail 14 is used to guide the material, so that when the pusher plate 9 pushes the material, the material moves in a straight line, thereby enabling the material to smoothly enter the grinding bin 4, achieving the purpose of improving the working efficiency. When the material passes through the feeding bin 12, the reciprocating motor 16 is started to drive the connecting member 15 to move reciprocally, thereby driving the first partition plate 18 and the second partition plate 19 to move reciprocally. When the first partition plate 18 and the second partition plate 19 move to the left, the material passes through the first through groove 20 and falls onto the second partition plate 19. When the first partition plate 18 and the second partition plate 19 move to the right, the first partition plate 18 isolates the material above, and the material on the second partition plate 19 falls onto the main board 2 through the second through groove 21. This process is repeated, ensuring that only one workpiece falls each time, thus eliminating the need for manual feeding and improving the feeding efficiency.
