When using the pharmaceutical preparation granule screening machine, the screen 16 is driven by the motor 2 to reciprocate, which can effectively separate the fine particles that meet the requirements and push them to the discharge port, facilitating the collection by the staff. The design of the disc 24 and the fixed column 25 enables the push plate 27 to reciprocate on the receiving table 35, pushing the screened particles towards the discharge port, preventing the blockage of the particles during the screening process, and ensuring the continuity and high efficiency of the screening process.

[0025] The output end of the motor 2 is fixedly connected with a first bevel gear 18. A second bevel gear 19 is meshed with the first bevel gear 18. A second rotating shaft 20 is fixedly connected to the second bevel gear 19. The second rotating shaft 20 is rotatably connected to the box body 1.

The receiving table 35 is fixedly connected to the box body 1. A feed hopper 28 is fixedly connected to the box body 1. A first discharge port 29 is fixedly connected to the box body 1. A second discharge port 30 is fixedly connected to the box body 1. A third discharge port 31 is fixedly connected to the box body 1. A box door 32 is slidably connected to the box body 1.

When using the pharmaceutical preparation granule screening machine, the staff can easily change the angle of the screen 16 by adjusting the handle 14, so as to change the movement track and speed of the material on the screen 16, so that the screening machine can adapt to the screening requirements of different material characteristics, achieve a more accurate screening effect, and effectively prevent the occurrence of blockage phenomena.

[0026] Working principle: When using the pharmaceutical preparation granule screening machine, the staff first turn on the motor 2. The motor 2 drives the first pulley 3 to rotate. The first pulley 3 drives the first belt 4 to rotate. The first belt 4 drives the second pulley 5 to rotate. The second pulley 5 drives the first rotating shaft 6 to rotate on the box body 1. The first rotating shaft 6 drives the cam 7 to rotate. The rotation of the cam 7 causes the fixed plate 11 on the roller 34 to drive the sliding rod 9 to slide in the spring 10. Thus, due to the shape of the cam 7 and the action of the spring 10, the fixed plate 11 moves up and down reciprocally. Then the fixed plate 11 drives the screen 16 to reciprocate through the support column 12 and the telescopic rod 17, which is suitable for screening during the screening of pharmaceutical preparation granules. At the same time, the motor 2 drives the first bevel gear 18 to rotate. The first bevel gear 18 drives the second bevel gear 19 to rotate. The second bevel gear 19 drives the second rotating shaft 20 to rotate on the box body 1. The second rotating shaft 20 drives the third bevel gear 21 to rotate. The third bevel gear 21 drives the fourth bevel gear 22 to rotate. The fourth bevel gear 22 drives the third rotating shaft 23 to rotate on the box body 1. The third rotating shaft 23 drives the disc 24 to rotate. The disc 24 eccentrically drives the fixed column 25 to rotate. The rotation of the fixed column 25 drives the ring 26 to move. The ring 26 drives the push plate 27 to slide on the receiving table 35, which is used to push the screened pharmaceutical preparation granules into the second discharge port 30 and the third discharge port 31. This is convenient for the staff to collect and at the same time prevents the pharmaceutical preparation granules from being blocked under long-term screening, thus affecting the screening efficiency. Then the pharmaceutical preparation granules are gradually placed on the feed hopper 28 and fall onto the screen 16 from the feed hopper 28. The screen 16 reciprocates to screen them. The screened pharmaceutical preparation granules fall on the receiving table 35 and slide out from the second discharge port 30 and the third discharge port 31 respectively through the reciprocating scraping of the push plate 27, which is convenient for the staff to collect. And the larger pharmaceutical preparation granules fall onto the first discharge port 29 through the inclined setting of the screen 16 and then fall into the collection container from the first discharge port 29, which is convenient for subsequent processing. When there are larger particles in the pharmaceutical preparation granules, the staff drive the box door 32 to slide to one side on the 1 by pulling the handle 33. Then turn the handle 14. The handle 14 drives the threaded lead screw 13 to rotate on the screen 16. The threaded lead screw 13 drives the screen 16 to rotate on the support column 12 through the threaded connection with the threaded sleeve 15. And the screen 16 simultaneously drives the telescopic rod 17 to expand and contract, thus completing the angle adjustment of the screen 16. By adjusting the angle of the screen 16, the movement trajectory and speed of the material on the screen 16 can be changed, thereby reducing the residence time of the larger particles and effectively reducing the occurrence of blockage phenomena.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
