The principle is that first, solid preparations of different sizes are loaded into the screening area inside the device through the feed port. Turn on the device, a vibration motor is provided in the device, and the screening bin 1 starts to work, generating vortex vibration. Under the action of vibration, the solid preparations are layered and graded through the screening bin 1, and larger particle materials gradually move downward from the upper layer of the material, and smaller particle materials are screened out through the screening bin 1. Solid preparations of different particle sizes screened out by the screening bin 1 are discharged from different distribution outlets respectively. This is the prior art.

[0027] A feeding pipe 2 is fixedly connected in the screening bin 1 , and a guide plate 5 is fixedly connected to the inner wall of the feeding pipe 2 . The middle part of the guide plate 5 is arc-shaped, and the guide plate 5 and the feeding pipe 2 form a feeding channel.

[0028] In addition, a buffer sleeve 3 is fixedly connected to the discharge pipe 2 through a connecting rod, and the buffer sleeve 3 cooperates with the guide plate 5. The top of the buffer sleeve 3 is arc-shaped, and the outside of the buffer sleeve 3 is provided with rubber, and the discharge end of the feed pipe 101 is toward the top of the buffer sleeve 3. When the solid preparation passes through the top of the buffer sleeve 3, the solid preparation can be buffered, which effectively reduces the impact force of the solid preparation, protects the integrity of the solid preparation, and reduces the phenomenon of drug particle breakage.

[0029] In addition, a driving machine 301 is fixedly connected inside the buffer sleeve 3, and a rotating shaft 302 is fixedly connected to the output end of the driving machine 301. The driving machine 301 can drive the rotating shaft 302 to rotate, and a soft strip 4 is fixedly connected to the rotating shaft 302, and the contact end of the soft strip 4 fits with the outside of the guide disk 5.

[0030] By utilizing the soft strip 4 to rotate on the guide disk 5, the solid preparation can be pushed to prevent the solid preparation from piling up on the guide disk 5, and the solid preparation can be moved into the material discharge channel to reduce the phenomenon of concentrated accumulation and falling of materials.

[0031] A guide plate 6 is also fixedly connected in the screening bin 1, and the middle part of the guide plate 6 is arc-shaped and the two ends are inclined and bent. One end of the guide plate 6 forms a diversion channel with the screening bin 1. A diversion plate 7 is arranged in the diversion channel, and the diversion plate 7 is spiral.

At this time, the solid preparation can be moved under the guidance of the limit frame 8 to the middle position of the screen of the screening bin 1 for screening and discharge, thereby preventing the screening bin 1 from accumulating.

[0034] The other part of the solid preparation will move to the diverter plate 7. During this process, the screening bin 1 is always in a vibrating state, and the spiral diverter plate 7 will distribute the solid preparation to the screen of the screening bin 1 for screening, thereby preventing the screen in the screening bin 1 from being filled up, so that it can continue to screen and discharge materials.
