[0029] As Figures 1 to 6 shown, a solid pharmaceutical preparation screening and packaging device includes: a fixed seat 1, with a fixing member 101 provided on the outside. A groove is provided inside the fixing member 101, and the groove penetrates the fixing member 101. A discharge pipe 104 is provided on the outside of the fixing member 101, and the discharge pipe 104 is communicated with the fixing member 101. A packaging machine 2 is provided on the outside of the discharge pipe 104; a screening mechanism, which is arranged inside the fixing member 101 and is used for screening the pharmaceutical agents. The screening mechanism includes a rotating assembly 4 and a screening assembly. The rotating assembly 4 is arranged inside the fixing member 101, and the rotating assembly 4 rotates relative to the fixing member 101. The screening assembly is arranged inside the rotating assembly 4, and the rotating assembly 4 drives the screening assembly to screen the solid pharmaceutical agents; a limiting assembly 3, which is arranged outside the screening assembly and is used for adjusting the screening diameter of the screening assembly. Specifically, during use, the screening assembly is driven to rotate through the cooperation of the fixed seat 1 and the rotating assembly 4. During the rotation process, the damaged solid pharmaceutical agents inside the screening assembly are separated. During the use process, the screening diameter of the screening assembly can be adjusted through the limiting assembly 3, so as to screen pharmaceutical agents of different sizes and increase the compatibility of screening. The packaging machine 2 can automatically count and package the screened pharmaceutical agents. The packaging machine 2 is a prior art and will not be explained in detail here.
[0030] As Figures 1 to 6 shown, one end of the fixing member 101 is further provided with a cover plate 102, and a feed hopper 103 is provided on the outside of the cover plate 102. Specifically, the feed hopper 103 is in a funnel shape, so as to guide the pharmaceutical agents when adding the pharmaceutical agents. The cover plate 102 and the fixing member 101 can be connected by a buckle or a thread. The cover plate 102 cooperates with the fixing member 101 to block the pharmaceutical agents inside the screening assembly and prevent the pharmaceutical agents from leaking during screening.
[0031] As Figures 1 to 6 shown, a collecting plate 105 is further provided inside the fixing member 101, and the collecting plate 105 is inclined. Specifically, the collecting plate 105 can be in a flat shape or an arc plate shape. The inclined collecting plate 105 guides the screened pharmaceutical agents, and the discharge pipe 104 is arranged at the bottommost side of the collecting plate 105, so as to discharge the pharmaceutical agents guided by the collecting plate 105 during the screening process.
[0032] As Figures 1 to 6As shown in the figure, the rotating assembly 4 includes a support tube 401 and a rotating ring 402. The support tube 401 is arranged inside the fixing member 101, and the support tube 401 rotates relative to the fixed seat 1. The rotating ring 402 is connected to the fixing member 101. A plurality of positioning pins 403 are arranged on the side of the rotating ring 402 relative to the support tube 401. The positioning pins 403 are connected to the support tube 401. A toothed ring 404 is arranged on the outer side of the rotating ring 402. A gear 406 is meshed inside the toothed ring 404. A fixing plate 405 is arranged on the outer side of the gear 406. The gear 406 rotates relative to the fixing plate 405, and the fixing plate 405 is connected to the fixing member 101. Specifically, the support tube 401 is inclined. The rotating ring 402 is rotatably connected to the fixing member 101. The positioning pins 403 connect the support tube 401 and the rotating ring 402 to ensure that the support tube 401 can rotate synchronously with the rotating ring 402. The gear 406 cooperating with the toothed ring 404 can drive the support tube 401 and the rotating ring 402 to rotate. While the support tube 401 rotates, the medicament inside the screening assembly is turned over, so as to realize the screening of the medicament.
[0033] As Figures 1 to 6 shown, the screening assembly includes a support plate 407. The support plate 407 is arranged inside the support tube 401. A through hole 410 is formed on one side of the support plate 407. A sieve plate 408 is arranged on one side of the support plate 407. The sieve plate 408 rotates relative to the support plate 407. A plurality of sieve hole groups 412 are formed inside the sieve plate 408. A plurality of limiting grooves 409 are formed on the other side of the support plate 407. A limiting assembly 3 for fixing the angle of the sieve plate 408 is further arranged on the outer side of the support plate 407. Specifically, the aperture sizes of the multiple groups of sieve hole groups 412 are different, so that different aperture sizes can be selected according to the use requirements during use. When screening the medicament, first rotate the sieve plate 408 to select a suitable sieve hole group 412 to coincide with the through hole 410, so as to complete the adjustment of the screening aperture. Then drive the support plate 407 and the sieve plate 408 to rotate through the support tube 401. During the rotation process, drive the medicament to move on the surface of the support plate 407, so as to avoid the medicament piling up at the through hole 410 during the screening process and causing blockage of the sieve hole groups 412, and ensure the stability of the medicament screening.
[0034] As Figures 1 to 6As shown, the limit component 3 includes a support block 301. The support block 301 is connected to the support plate 407. A cavity is provided inside the support block 301. A connecting plate 303 is provided inside the cavity. The connecting plate 303 moves relative to the support block 301, and the moving direction of the connecting plate 303 is parallel to the height direction of the support block 301. A threaded rod 302 is provided on one side of the connecting plate 303, and the threaded rod 302 penetrates through the support block 301. A plurality of limiting rods 304 are provided on the other side of the connecting plate 303. A plurality of limiting blocks 305 are movably connected inside the support block 301, and the limiting blocks 305 correspond to the limiting rods 304 one by one. The limiting blocks 305 are adapted to the limiting grooves 409. Specifically, the adaptation of the limiting blocks 305 to the limiting grooves 409 means that the limiting blocks 305 can be inserted into the limiting grooves 409 and fix the angle of the sieve plate 408 to prevent the sieve plate 408 from rotating relative to the support plate 407 during use. The support block 301 is connected to the sieve plate 408, so that the sieve plate 408 can be controlled through the support block 301. The threaded rod 302 cooperates with the connecting plate 303 and the limiting rods 304 to control the relative positions of the limiting blocks 305. When the sieve plate 408 needs to be rotated, first, the threaded rod 302 drives the connecting plate 303 and the limiting rods 304 to separate from the limiting blocks 305, so that the limiting blocks 305 can slide inside the support block 301. Then, the sieve plate 408 is rotated. After the rotation is completed, the threaded rod 302 drives the connecting plate 303 and the limiting rods 304 to move in the reverse direction. The limiting rods 304 moving in the reverse direction contact the limiting blocks 305 to fix the positions of the limiting blocks 305. While the positions of the limiting blocks 305 are fixed, the angle of the sieve plate 408 is fixed in cooperation with the limiting grooves 409 to prevent the sieve plate 408 from rotating relative to the support plate 407 during use, resulting in a change in the diameter of the pharmaceutical screening.
