Capsule polishing machine capable of improving sorting precision

Abstract

The invention relates to the technical field of pharmaceutical equipment and discloses a capsule polishing machine capable of improving sorting precision. The capsule polishing machine comprises a base, a barrel fixedly connected to the outer side of the upper end of the base, a sliding groove fixedly connected to the upper end of the inner wall of the barrel, an end cover movably sleeved with thesliding groove, handles fixedly connected to two sides of the upper end of the end cover, and supporting rods fixedly connected with the two sides of the inner wall of the barrel are arranged below the sliding groove. When a negative air pressure device in a waste remover of existing capsule polishing equipment absorbs unqualified capsules, due to the fact that a large number of capsules fall down, part of the unqualified capsules located in the middle are prone to being blocked by external qualified capsules and are difficult to be attracted by negative pressure, and the unqualified capsuleson the outer side are easily influenced by the capsules falling from the upper part when being attracted, so that the unqualified capsules are easily not absorbed under the interference of other capsules, a large number of unqualified capsules are mixed into qualified capsules, the screening precision is difficult to guarantee, and great influence is brought to the use of subsequent capsules in the medical treatment process.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical equipment, in particular to a capsule polishing machine for improving sorting accuracy. Background technique [0002] Capsule polishing machine is a special polishing equipment for capsules and tablets. It can remove the dust on the surface of capsules and tablets and improve the surface finish. It is suitable for the production of various capsules and tablets. The polishing machine is mainly composed of a hopper, a polishing cylinder, a brush, and a motor. , waste removal head, discharge hopper, vacuum cleaner and frame, etc. Its working principle is to drive the capsule to make a circular spiral movement along the wall of the polished tube through the rotating motion of the brush, so that the capsule advances along the helical spring, and is in contact with the brush, Under the continuous friction of the polishing cylinder wall, the outer surface of the capsule shell is polished, and the ...

AI Technical Summary

Problems solved by technology

[0004] 1. When the negative wind pressure device in the waste removal device of the existing capsule polishing equipment absorbs unqualified capsules, due to the falling of a large number of capsules, some unqualified capsules located in the middle are easily blocked by the external qualified capsules, and are difficult to be blocked by negative pressure. Attraction, and the unqualified capsules located on the outside are easily affected by the capsules falling above them when they are attracted, resulting in the unqualified capsules being easily not absorbed under the interference of other capsules, resulting in a large number of unqualified capsules mixed into the qualified capsules, It is difficult to guarantee the screening accuracy, which has a huge impact on the use of subsequent capsules in the medical process

[0005] 2. The existing polishing machine will use a vacuum cleaner to remove the dust and polished waste on the surface of the capsule when polishing the capsule with a brush. However, when a large number of capsules are polished inside the polishing machine due to the rotational force of the brush The extrusion of a large number of capsules leads to a relatively tight fit between a large number of capsules. Not only is it difficult to ensure that the capsules are fully polished, but also when the dust and waste are sucked, usually only the dust that is randomly exposed on the surface can be absorbed cleanly, and the polishing and dust absorption effects are excellent.
