The downward rotating dustproof plate no longer blocks the feed hopper of the crusher body, and the raw material falls downward along the inclined anti-sticking pad. It slides into the grinder body, and the grinder body starts to crush the raw materials. After the raw materials are separated from the anti-sticking pad, the anti-sticking pad no longer squeezes the piezoelectric sensor, and the servo motor drives the worm gear to rotate in the opposite direction through the worm, and the reverse rotating worm gear drives the connecting plate and the dustproof plate to rotate upward, and the upward rotating dustproof plate will block the feed hopper of the grinder body again. When feeding, workers do not need to manually open the feed hopper, which solves the problem that the existing raw material crushing device is equipped with a sealing cover at the feed port to prevent dust from entering. Workers need to remove the sealing cover when feeding, and put the seal back after feeding is completed, which is a time-consuming and labor-intensive operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0024] A tablet raw material pulverizing device includes a pulverizer body 1, a dustproof mechanism 2 is provided on the outer wall of the feed hopper of the pulverizer body 1, a controller 3 is mounted on the outer wall of the pulverizer body 1, a terminal 4 is mounted on the outer wall of the pulverizer body 1 near the controller 3, and a conveyor plate 5 is fixedly connected to the discharge port of the pulverizer body 1;

[0025] The conveying plate 5 is made of ABS plastic and has a semicircular structure. The connection between the controller 3 and the terminal 4 is an electrical connection.

[0026] In this embodiment, reference Figure 2 and Figure 3 The dustproof mechanism 2 includes a fixed frame 201 fixedly connected to the outer wall of the feed hopper of the crusher body 1, a rotating shaft 202 fixedly connected inside the fixed frame 201, a connecting plate 203 fixedly connected to the outer wall of the rotating shaft 202 inside the fixed frame 201, a dustproof plate 204 fixedly connected to the outer wall of the connecting plate 203 outside the fixed frame 201, a sealing gasket 205 fixedly connected to the outer wall of the dustproof plate 204 away from the rotating shaft 202, and a top of the dustproof plate 204 fixedly connected to the outer wall of the dustproof plate 204. There is a support block 206, a top of the support block 206 is fixedly connected to an anti-sticking pad 207, a piezoelectric sensor 208 is fixedly connected to the inside of the dustproof plate 204 and below the anti-sticking pad 207, a worm gear 209 is fixedly connected to the outer wall of the connecting plate 203 and near the rotating shaft 202, a worm 210 is meshedly connected to the outer wall of the worm gear 209 and on the side away from the connecting plate 203, and a servo motor 211 is fixedly connected to the top of the worm gear 210 and inside the fixed frame 201;

[0027] The fixing frame 201, the connecting plate 203 and the dustproof plate 204 are all made of aluminum alloy. The shape of the fixing frame 201 is adapted to the shape of the feed hopper of the grinder body 1. The connection between the worm 210 and the fixing frame 201 is a rotating connection. The sealing gasket 205 is made of silicone. The rotating shaft 202, the connecting plate 203, the dustproof plate 204 and the worm gear 209 are all provided in two groups. The connection between the connecting plate 203 and the dustproof plate 204 and the fixing frame 201 is a sliding connection. The anti-sticking pad 207 is made of PVC plastic film, the support block 206 is a ring structure design, and the dustproof plate 204 is a trapezoidal structure design. The connection between the servo motor 211, the piezoelectric sensor 208 and the controller 3 is an electrical connection.

[0028] The working process of the utility model is as follows: when the tablet raw material crushing device designed by the present invention is in operation, the raw material is put into the feed hopper of the crusher body 1, and the raw material will fall downward onto the anti-sticking pad 207 on the top of the dustproof plate 204, and the raw material will squeeze the piezoelectric sensor 208 under the anti-sticking pad 207. When the piezoelectric sensor 208 is squeezed, it will input a signal to the controller 3, and the controller 3 will start the servo motor 211. The servo motor 211 will drive the worm gear 209 to rotate through the worm 210, and the worm gear 209 will drive the connecting plate 203 and the dustproof plate 204 to rotate downward. The downward rotating dustproof plate 204 no longer blocks the feed hopper of the grinder body 1, and the raw materials slide down along the inclined anti-sticking pad 207 into the grinder body 1. The grinder body 1 begins to crush the raw materials. After the raw materials are separated from the anti-sticking pad 207, the anti-sticking pad 207 no longer squeezes the piezoelectric sensor 208, and the servo motor 211 drives the worm gear 209 to rotate in the opposite direction through the worm 210. The reverse rotating worm gear 209 drives the connecting plate 203 and the dustproof plate 204 to rotate upward, and the upward rotating dustproof plate 204 will block the feed hopper of the grinder body 1 again.
