[0029] The driving mechanism includes a motor 13, and an L-shaped fixing plate 14 is fixedly connected to one side of the box body 2, and the motor 13 is fixedly connected to one side of the fixing plate 14. The output shaft of the motor 13 rotates through the fixing plate 14, and the end of the output shaft of the motor 13 is fixedly connected to the first connecting rod 7, and the end of the first connecting rod 7 is rotatably connected to the second connecting rod 15. The two adjacent surfaces of the first connecting rod 7 and the second connecting rod 15 are slidably matched.

[0030] A fixed shaft 17 is fixedly connected to one side of the sieve plate 5 , one end of the fixed shaft 17 passes through the slide slot 12 and extends to the outside of the box body 2 , and the second connecting rod 15 is rotatably sleeved on the fixed shaft 17 at one end away from the first connecting rod 7 .

[0031] The top of the box body 2 is fixedly connected with the granulator body 1, and the discharge port of the granulator body 1 is located just above the sieve plate 5. The granules produced by the granulator body 1 fall on the sieve plate 5.

[0032] A dust suction component is provided on the box body 2 , and a dust suction port of the dust suction component is located directly above the sieve plate 5 .

[0033] The dust suction assembly includes an air pump 9, which is fixedly connected to the inner wall of the box body 2. The air outlet pipe of the air pump 9 passes through the side of the box body 2 and extends to the outside of the box body 2, and one end of the air inlet pipe of the air pump 9 is fixedly connected to the air suction port 8. Both ends of the air suction port 8 are fixed to the inner wall of the box body 2. The length of the air suction port 8 is adapted to the moving range of the sieve plate 5, so that the air suction port 8 can suck away the medicine powder scattered on the sieve plate 5 when the sieve plate 5 moves to different positions. A filter screen is provided at the air inlet of the air suction port 8, which can block the medicine particles to prevent the medicine particles from being sucked away when the suction force is too large.

[0034] The collecting box 3 is fixedly connected to one side of the box body 2 near the air pump 9, and a filter plate 10 is slidably arranged inside the collecting box 3. The end of the air outlet pipe of the air pump 9 is located in the collecting box 3 and above the filter plate 10, and the bottom of the collecting box 3 is open. The gas discharged by the air pump 9 is discharged through the opening, and the absorbed powder is filtered on the filter plate 10.

[0035] Both ends of the filter plate 10 are fixedly connected with sealing plates 4, and a through hole is provided on the collection box 3. Two sealing plates 4 are arranged in the through hole, and a magnet 11 is fixedly connected to one side of one sealing plate 4. The top of the magnet 11 extends to the outside of the sealing plate 4, and a magnetic block matching the magnet 11 is provided on the side of the collection box 3, and the magnet 11 and the magnetic block attract each other. A handle is also fixed on one sealing plate 4 fixed with the magnet 11.

[0036] Support legs are fixedly connected to the four corners of the bottom of the box body 2, and a material receiving box 6 is arranged below the box body 2. One end of the sieve plate 5 extending outside the box body 2 is located above the material receiving box 6. The medicine particles on the sieve plate 5 fall into the material receiving box 6 for collection.

[0037] A discharge hole 18 is provided on the side of the box body 2, and the discharge hole 18 is located below the sieve plate 5. When the sieve plate 5 is in use, part of the powder will fall to the bottom surface of the inner cavity of the box body 2, and an air pump connected to the discharge hole 18 can be used to extract the powder.

[0038] Working principle:

[0039] When in use, the starter motor 13 drives the first connecting rod 7 to rotate, and the second connecting rod 15 pushes the fixed shaft 17 to make the screen plate 5 slide back and forth inside the box body 2. At the same time, the T-shaped block 16 slides inside the chute 12.

[0040] Start the air pump 9 to inhale air at the air inlet 8, and the inhaled air is discharged into the collection box 3, and then passes through the filter plate 10 and is discharged through the opening at the bottom of the collection box 3. The suction force of the air pump 9 should not be too large to prevent the air inlet 8 from sucking away the medicine particles together.

[0041] The material is placed in the granulator body 1 for processing, and the prepared granules fall onto the sliding screen plate 5. Since the screen plate 5 is inclined, the granules will roll while sliding downward. The powder on the surface of the granules will fall off while the air inlet 8 will suck away the powder that falls off during the rolling process of the granules, thereby cleaning different surfaces of the granules to achieve a better cleaning effect.

[0042] The medicine particles will fall into the material receiving box 6 after passing through the air inlet 8. The medicine powder sucked away by the air inlet 8 will be blown into the collecting box 3, and then filtered by the filter plate 10, so that the medicine powder is collected on the top of the filter plate 10.

[0043] When the filter plate 10 needs to be cleaned, the handle is pulled to drive the sealing plate 4 and the magnet 11 to slide toward the outside of the collecting box 3, and the magnet 11 leaves the magnetic block on the collecting box 3. Until the filter plate 10 is completely slid out, the powder on the filter plate 10 is cleaned.

[0044] After cleaning, the filter plate 10 is pushed into the collection box 3 so that the magnet 11 is attracted to the magnetic block and the filter plate 10 is fixed for reuse.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
