Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a screening device for pharmaceutical preparation particles. Background Technology

[0002] In the production process of pharmaceutical granules, it is necessary to screen the granules and remove those with larger particle sizes. According to the patent authorization announcement number: CN213194565U, a pharmaceutical granule screening device is disclosed. This utility model discloses a pharmaceutical granule screening device, which includes a box body. The upper end of the box body is provided with a feeding hopper. The two sides of the feeding hopper are provided with first spring assemblies. The two sides of the lower end of the feeding hopper are provided with support rods. The two sides of the inside of the box body are provided with first cylinders. The telescopic end of the first cylinder is provided with a buffer block. The lower part of the first cylinder is provided with a support plate. The upper end of the support plate is provided with a groove near the support rod.
