Abstract

A tablet crushing, sieving and mixing device comprises a frame, a grinding mechanism and a sieving and mixing mechanism are arranged in sequence from top to bottom in the frame, and the grinding mechanism comprises a grinding bin, an active grinding roller and a driven grinding roller, the active grinding roller and the driven A grinding cavity is formed between the grinding rollers. The upper end of the grinding chamber is provided with a feeding port, and the grinding chamber is provided with a scraper. The length of each scraper is set so that each scraper is tangent to the outer circumference of the corresponding grinding roller. It is set so that the scraper can scrape off the powder adhering to the moving grinding roller, and a discharge channel is formed between the two scrapers; the sieve mixing mechanism includes a sieve cylinder, a rotating support shaft and a motor II, the motor Ⅱ Drive the rotating support shaft to drive the sieve drum to rotate, the inlet of the sieve drum corresponds to the discharge channel, and the circumferential surface of the sieve drum is a screen structure; the bottom of the sieve mixing mechanism is provided with a receiving container, and the upper end of the receiving container and the lower end of the sieve drum are Take over the settings. The device of the invention integrates tablet crushing, powder mixing and sieving, and is flexible in use and sufficient in grinding.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a tablet crushing, sieving and mixing device. Background technique [0002] When people are sick, doctors often prescribe some tablet medicines for patients to take according to the condition. Solid tablet medicines are generally swallowed or chewed, but for infants or some special patients, swallowing or chewing is not recommended. Chewing is more difficult, so it is necessary to grind the tablet into powder before taking it, and crush the solid tablet into powder. This situation is mostly for infants or patients who need to divide the tablet into several portions. The existing tablet crushing method Most of them are manually pulverized, which requires a lot of effort, brings inconvenience to patients or medical staff, and the operation is complicated. [0003] In addition, especially for infants and young children, if multiple types of medicines need to be taken, it is often...
