[0021] The top of the fixed block 8 is set as an inclined surface, the end of the rotating rod 7 away from the servo rod 5 is set as an arc surface, and a No. 1 spring is arranged between the fixed ring 10 and the crushing frame 1, and the No. 1 spring can drive the fixed ring 10 to reset.

[0022] The crushing device 3 is in contact with the operating hole 12, the feeding frame 2 is connected to the inside of the crushing frame 1, and an auxiliary frame 151 is fixedly installed on the top of the crushing frame 1. The tablets entering the crushing frame 1 are broken up by the dispersion rod 9 and fall evenly into the crushing device 3 under the action of their own gravity.

[0023] When this embodiment is working: the tablets to be ground are put into the pulverizing frame 1 through the feeding frame 2, and the servo motor 4 drives the servo rod 5 to rotate. The rotation of the servo rod 5 drives the hollow rod 6 to rotate. The rotation of the hollow rod 6 drives the rotating rod 7 to rotate. The rotating rod 7 rotates and contacts the inclined surface of the fixed block 8 and squeezes the fixed block 8. The rotating rod 7 is subjected to the reaction force of squeezing the fixed block 8 and moves in the direction away from the servo motor 4.

The dispersion rod 9 reciprocates to break up the tablets entering the crushing frame 1. After being broken up by the dispersion rod 9, the tablets entering the crushing frame 1 fall evenly into the crushing equipment 3 under the action of their own gravity. At the same time, the crushing equipment 3 operates to grind the tablets.

[0024] See also Figure 1-Figure 8 On the basis of the above embodiment, in another embodiment of the present invention, a shielding device for controlling the feeding amount of tablets is provided on the top of the inner wall of the crushing frame 1, and an auxiliary device is provided on the top of the crushing frame 1.

By controlling the feeding speed of the tablets, excessive tablets are prevented from accumulating inside the crushing frame 1, ensuring that the tablets can fully contact with the crushing device 3, thereby improving the crushing effect.

[0025] A reset spring 147 is arranged between the support plate 142 and the crushing frame 1, the support plate 142 is in contact with the feed plate 143, and a No. 2 spring is arranged between the sealing plate 146 and the feed frame 2. The No. 2 spring can drive the sealing plate 146 to reset, and the sealing plate 146 can ensure the sealing of the feed frame 2, effectively seal and avoid dust loss, protect the health of the operator, and reduce pollution to the environment.

[0026] The auxiliary device includes an auxiliary rod 152, a polygonal plate 153, an adding hole 154, a connecting hole 155, a placement slot 156, a tooth block 157, a moving rod 158, a gear 159 and a stirring rod 1510. The auxiliary rod 152 is fixedly mounted on the left side of the auxiliary frame 151, and the polygonal plate 153 is slidably mounted on the circumferential surface of the auxiliary rod 152. The adding hole 154 is provided at the bottom of the inner wall of the auxiliary frame 151, the connecting hole 155 is provided at the top of the inner wall of the crushing frame 1, and the placement slot 156 is provided at the polygonal plate 15 3, the gear block 157 is fixedly installed on the inner wall of the placement groove 156, the moving rod 158 rotates and penetrates the top of the auxiliary frame 151, the gear 159 is fixedly installed on the circumferential surface of the moving rod 158, and the stirring rod 1510 is fixedly installed on the circumferential surface of the moving rod 158.

The anti-caking agent can be evenly stirred by rotating the stirring rod 1510 to avoid the problem of clogging of the adding hole 154 due to the agglomeration of the anti-caking agent.

[0027] A No. 3 spring is arranged between the polygonal plate 153 and the auxiliary frame 151 , and the No. 3 spring can drive the polygonal plate 153 to reset.

[0028] The tooth block 157 is meshed with the gear 159, and a granular anti-caking agent is arranged inside the auxiliary frame 151. The adding hole 154 is in contact with the connecting hole 155. The moving rod 158 rotates to drive the stirring rod 1510 to rotate to stir the anti-caking agent inside the auxiliary frame 151 to prevent the anti-caking agent inside the auxiliary frame 151 from clumping.

[0029] When the present embodiment is working, the rotating rod 7 moves in the direction away from the servo motor 4, driving the hollow rod 6 to move. The hollow rod 6 moves and drives the linkage ring 13 to move and contact the support plate 142 and squeeze the support plate 142. The support plate 142 is squeezed by the linkage ring 13 and moves in the direction away from the servo motor 4. The support plate 142 moves in the direction away from the servo motor 4 and squeezes the reset spring 147. The reset spring 147 is squeezed by the support plate 142 to deform and accumulate force. At the same time, the support plate 142 moves in the direction away from the servo motor 4, disengages from the contact with the feed plate 143 and releases the shielding of the feed frame 2. After the shielding of the feed frame 2 is released, the tablets inside the feed frame 2 quickly enter the inside of the crushing frame 1 through the feed frame 2. When the fixed ring 10 moves and resets in the direction close to the servo motor 4, driving the hollow rod 6 to move and reset, the hollow rod 6 moves and resets and drives the linkage ring 13 to move and reset. The linkage ring 13 moves and resets and disengages from the support plate 1 42, the support plate 142 is separated from the contact with the linkage ring 13, so that the support plate 142 moves and resets in the direction close to the servo motor 4 under the elastic force of the reset spring 147, and the support plate 142 moves and resets in the direction close to the servo motor 4 to contact the feed plate 143 and restore the shielding of the feed frame 2. When putting the tablets into the feed frame 2, first manually pull the sealing plate 146 to the right side, and the sealing plate 146 moves to the right side to squeeze the No. 2 spring. The No. 2 spring is squeezed by the sealing plate 146 to produce deformation and accumulate force. At the same time, the sealing plate 146 moves to the right side to release the seal on the top of the feed frame 2. After the seal on the top of the feed frame 2 is released, the tablets are put into the feed frame 2. After the tablets are put into the feed frame 2, the sealing plate 146 is manually loosened so that the sealing plate 146 is reset to the left side under the elastic force of the No. 2 spring. The sealing plate 146 resets to the left side to restore the seal of the feed frame 2 to prevent dust leakage during tablet grinding.

[0030] The support plate 142 moves in a direction away from the servo motor 4 and contacts and squeezes the polygonal plate 153. The polygonal plate 153 is squeezed by the support plate 142 and moves in a direction away from the servo motor 4. The polygonal plate 153 moves in a direction away from the servo motor 4 to pull the No. 3 spring. The No. 3 spring is pulled by the polygonal plate 153 and deforms and accumulates force. At the same time, the polygonal plate 153 moves in a direction away from the servo motor 4 and breaks away from the contact with the adding hole 154. The polygonal plate 153 breaks away from the contact with the adding hole 154, so that the anti-caking agent inside the auxiliary frame 151 enters the inside of the pulverizing frame 1 through the adding hole 154 and the connecting hole 155 and mixes with the ground tablets. When the support plate 142 moves closer to the servo motor 4, the No. 3 spring is deformed and accumulates force. When the servo motor 4 moves in the direction of reset, the support plate 142 breaks away from the contact with the polygonal plate 153 toward the direction close to the servo motor 4, so that the polygonal plate 153 moves toward the direction close to the servo motor 4 under the elastic force of the No. 3 spring, and the polygonal plate 153 moves toward the direction close to the servo motor 4 to restore the covering of the top of the adding hole 154. At the same time, the polygonal plate 153 moves in the direction away from the servo motor 4, driving the tooth block 157 to move, and the tooth block 157 moves to squeeze the gear 159 to rotate, and the gear 159 rotates to drive the moving rod 158 to rotate, and the moving rod 158 rotates to drive the stirring rod 1510 to rotate to stir the anti-caking agent inside the auxiliary frame 151 to prevent the anti-caking agent inside the auxiliary frame 151 from clumping.
