A drug particle screening device

Abstract

The invention discloses a drug particle screening device, and belongs to the technical field of drug preparation. The drug particle screening device comprises a feeding mechanism, a cabinet body, a screening mechanism and a recycling mechanism, wherein the feeding mechanism is installed at the top of the cabinet body; the screening mechanism and the recycling mechanism are both arranged in the cabinet body; a circulating mechanism is arranged on the side of the cabinet body and comprises a circulating assembly and a receiving assembly; one end of the circulating assembly extends into the feeding mechanism, and the other end of the circulating assembly extends into the receiving assembly; and one end of the receiving assembly penetrates through the side wall of the cabinet body to be matched with the recycling mechanism. According to the drug particle screening device, when large-particle medicines are clamped in screening holes, a driving motor drives a driving gear on an output shaftof the driving motor to rotate, and the driving gear rotates to drive a shifting gear meshing with the driving gear and a repressing roller fixedly connected with the shifting gear to roll the large-particle medicines getting stuck in the screening holes so that the crushed medicines can be small enough to pass through the screening holes, so that the situation that the large-particle medicines block the screening holes so as to reduce the screening efficiency is avoided.

Description

technical field [0001] The invention relates to the technical field of medicine preparation, in particular to a drug particle screening device. Background technique [0002] Drugs refer to chemical substances that can affect the physiological, biochemical and pathological processes of the body, and are used for the prevention, diagnosis, treatment of diseases and family planning. Drugs include hypnotics, cold medicines, antipyretics, stomach medicines, laxatives, etc. that are beneficial to health. Drugs can be purchased in pharmacies, prescription drugs must be purchased with a prescription, and there are great differences between drugs and drugs. Among them, filtering and screening devices are often used in the production process of granular drugs. The traditional filtering and screening devices have complex structures and cumbersome operations. They mainly use motors to drive the screen to vibrate to achieve drug screening. People supervise at all times, which increases...
