Medicine powder grinding device for capsule tablet preparation

Abstract

The invention discloses a medicine powder grinding device for capsule tablet preparation. The medicine powder grinding device comprises a base, a rack, a grinding box, a driving motor, a semi-gear, a collision head, a grinding head, a preliminary grinding cavity and exquisite grinding cavities; the other end of a fixed support is fixedly provided with the driving motor, an output shaft of the driving motor is forward, the semi-gear is installed on the output shaft of the driving motor in an interference fit manner, a grinding shaft is installed at a gear core in an interference fit manner and extends into the preliminary grinding cavity, the grinding head is installed in the preliminary grinding cavity, a screen net is connected to the interior of the grinding box through a neck, and the two exquisite grinding cavities are further arranged inside the grinding box. According to the grinding device, the collision head is arranged, and therefore medicine powder can be effectively prevented from adhering to the inner wall of the grinding box; through left-right movement of the grinding box, the medicine powder screening speed is increased; and meanwhile, through the arrangement of the preliminary grinding cavity and the exquisite grinding cavities, medicine powder grinding is more sufficient, and the human body absorbing speed after a tablet is taken by a patient is increased.

Description

technical field [0001] The invention relates to a grinding device, in particular to a grinding device for preparing medicine powder from capsule medicine particles. Background technique [0002] Drugs packed in capsules are generally powders or granules that are irritating to the esophagus and gastric mucosa, or drugs that taste bad, are easy to volatilize, are easily decomposed by saliva in the mouth, and are easy to inhale into the trachea. These medicines are packed into capsules, which not only protects the properties of the medicine from being destroyed, but also protects the digestive organs and respiratory tract. Removing the capsule shell may result in drug loss, drug waste, and reduced drug efficacy. In addition, some drugs need to be dissolved and absorbed in the intestines, and the capsules protect the drugs from being destroyed by gastric acid. In medicine, it refers to a capsule made of special film-forming materials (such as gelatin, cellulose, polysaccharide...

AI Technical Summary

Problems solved by technology

[0003] The drug powder in the capsule generally needs to be finely ground before it can be loaded into the capsule, so as to facilitate the absorption of the human body. However, the existing drug powder grinding device often causes the drug powder to adhere to the inner wall of the grinding box during grinding, and the grinding effect is relatively low. Poor, there will still be large particles of powder after grinding
