Efficient medicine grinding device

Abstract

The invention discloses an efficient medicine grinding device which comprises a machine body and a base, wherein a casing shell is in rotatable connection to the inner wall of the machine body; a rotation cylinder is in sealed threaded connection to a rotation center of the top of the cashing shell; a slide cavity is formed in the inner wall of the rotation cylinder; a slide plate is in sealed slide connection inside the slide cavity; a push rod is fixedly connected to the top of the slide plate; a press plate is fixedly connected to the top of the push rod; a grinding ball is welded on the bottom of the rotation cylinder; the outer wall of the grinding ball is sleeved by a rubber cover; and the rubber cover is filled with a magneto-rheological fluid. A feeding hole is formed in the top ofthe cashing shell, and the feeding hole is in sealed rotatable connection to a feeding plate. The efficient medicine grinding device disclosed by the invention has the beneficial effects that based on a characteristics of the magneto-rheological fluid that the fluid turns to a solid under magnetic field effects, a rubber layer can clean powder carried by a surface during extension and contractionthrough contact and separation of the slide plate and a conductor plate; and through breakdown of a metal plate capacity for recovery of metal constitution, auxiliary pushing of grinding of the grinding ball can be realized, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of medicine preparation, in particular to a high-efficiency medicine grinding equipment. Background technique [0002] In the development and preparation of medicines, it is usually necessary to grind the medicines into fine powders for tablet medicines, and then press the medicines into tablets, which is convenient for patients to take quantitatively; in the process of medicine grinding, a grinder is needed, Drug grinding usually uses a spherical grinder, so that the drug is concentrated at the bottom of the grinder, and can be squeezed and ground conveniently; since the radius of curvature of the grinding rod is inconsistent with the radius of curvature of the inner bottom of the grinder, the grinding process is like two The inscribed spherical surface can only achieve point contact, and the grinding efficiency is greatly reduced at this time; [0003] After retrieval, China Authorized Patent No. CN107020...

Problems solved by technology

[0003] After retrieval, China Authorized Patent No. CN107020184B discloses a solid drug grinder, the solid drug grinder includes a grinding disc and a grinding rod, and the grinding rod includes a handle and a grinding ball installed at the handle; in the grinding The outside of the ball is wrapped with an elastic layer, and the spherical space is filled with regulating liquid, which can effectively increase the grinding speed, enhance the grinding effect, effectively prevent the splashing and collapse of the drug, and realize the efficient and safe preparation of the drug. After analysis, this prior art The grinding area is increased through the elastic layer and the adjusting liquid, but in actual use, due to the good ductility of the elastic layer and the liquid, when the drug is stressed, the force is scattered and the grinding effect is poor. It takes a lot of energy and wastes labor costs. At the same time, during drug grinding, a large amount of drug powder will stick to the outside of the elastic layer when it is heated, which is difficult to clean and cause drug waste. Based on this, the present invention designs a high-efficiency drug grinding equipment
