[0002] Granules refer to dry granular preparations with a certain particle size made by mixing raw materials and suitable excipients. Screening in granule production is a key step to ensure that the particle size is uniform and meets quality standards.

[0003] A screening device for granule production, disclosed in CN 214812613 U, can perform multi-stage screening of granules, realize the screening and collection of granules of different sizes, is easy to use, the granules fall freely under the action of gravity, the discharge is smooth, and the lifting and lowering of the screening disc prevents the granules from clogging the filter screen at the bottom of the screening disc.

[0004] The screening device for granule production uses a threaded rod to move the screening disc downwards. However, the speed at which the threaded rod moves the screening disc downwards is relatively small, resulting in a small amplitude of granule shaking, making it difficult to screen the granules. Therefore, improvements are needed. Utility Model Content
