Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical machinery, and particularly relates to a centrifugal pill selecting machine. Background Art

[0002] The pill selecting machine is a supporting equipment for pill production, which can screen defective pills such as non-round or multi-particle adhesion pills to make the roundness of the pills consistent. At present, the spiral pill selecting machine is mostly used on the market. It feeds the pills into the high inlet, and the pills roll down naturally along the spiral track by their own weight, and uses the rotational speed difference between good and bad pills to sort the pills respectively.

[0003] However, the above operation method has the following defects, which are as follows:

[0004] 1. Since the pills roll down naturally along the spiral track by their own weight, for pills with different diameters and weights, there are differences in their sorting effects. And the equipment is of an integrated design, and the spiral track is relatively fixed, making it difficult to adjust its rolling speed by adjusting the track slope and height, so the applicability is poor;

[0005] 2. During the process of the pills rolling down naturally along the spiral track, under the action of centrifugal force, the pills concentrate on the outer side of the track and roll down from top to bottom. Due to the high speed, the distance between the pills is very close, and defective pills such as non-round or multi-particle adhesion pills are easily carried forward by the surrounding pills, so it is very difficult to separate defective pills with low speed or inconsistent movement directions, resulting in poor sorting effects;

[0006] 3. The equipment is of an integrated design and is relatively high, making it difficult to disassemble and clean;

[0007] Therefore, it is of great significance to study a new centrifugal pill selecting machine to solve the above problems. Content of the Utility Model
