The medicine cap and the method of medicine filling

Abstract

The invention discloses a drug-feeding cap and a drug-feeding method, which comprise a fixed shell, a metering plate, a shielding plate and a rotating shell which are overlapped in order from top to bottom and coaxially arranged, a circular through hole is set in the middle of the shielding plate, and the metering There is a downward triangular protrusion in the middle of the bottom surface of the plate, and a triangular groove is correspondingly provided on the rotating shell, and the triangular protrusion passes through the circular through hole to fit in the triangular groove, and uses a screw to pass through the metering plate from top to bottom , the metering plate is connected and fixed with the rotating shell, and the metering plate can rotate freely between the shielding plate and the fixed shell. There are support blocks. When the lower drug cover of the present invention is assembled to the drug cover installation port of the drug dispensing machine, the fixed shell is stuck at the drug cover installation port by rotating the lower drug cover, so that the lower drug cover is vertically limited to prevent it from being lifted by the transmission part .

Description

technical field [0001] The invention relates to a medicine automatic dispensing and metering device in a medicine dispensing system, in particular to a medicine cap and medicine filling method. Background technique [0002] my country's traditional Chinese medicine culture has a long history and is rich in traditional Chinese medicine resources. In recent years, due to the outstanding advantages of traditional Chinese medicine such as good curative effect, less side effects, and less environmental pollution, the "traditional Chinese medicine craze" has become popular in the world. However, at present, China only accounts for a small part of the export volume of traditional Chinese medicine in the world. The main reason is that my country is still using the traditional method of dispensing raw crude medicine and weighing by hand. The speed of dispensing traditional Chinese medicine is slow and the measurement error Large, and it is difficult to connect with the standardized, ...

Problems solved by technology

However, at present, China only accounts for a small part of the export volume of traditional Chinese medicine in the world. The main reason is that my country is still using the traditional method of dispensing raw crude medicine and weighing by hand. The speed of dispensing traditional Chinese medicine is slow and the measurement error Large, and it is difficult to integrate with the standardized, standardized and scientific international market for dispensing

[0003] In order to solve the above-mentioned problems, a medicine dispensing machine has appeared on the market, but the medicine cap that cooperates with the medicine bottle in the existing medicine dispensing machine has the following deficiencies: (1) the metering plate and the movable housing of the existing medicine cap are used The screws are connected and fixed from bottom to top. Long-term use will cause the screws to loosen or even fall off completely; (2) There is a gap on the outer wall of the drug cover, which is prone to material leakage and running, resulting in material loss and affecting the measurement accuracy; (3) ) The rotating shell and the metering plate are connected by screws, and the screws drive the metering plate to rotate. The screws need to bear a large shear force, which may easily cause the screws to break

(4) If the medicine in the medicine bottle absorbs moisture and agglomerates, the existing lower medicine cap cannot handle it, and there is a phenomenon that the medicine in the medicine hole is distributed unevenly

(5) For powdery medicinal materials, stagnation is prone to occur during the feeding process, and the medicinal materials do not fall automatically. It needs to be tapped outside the medicine bottle to make the medicinal materials fall again.

(6) When the existing medicine cap cooperates with the transmission part to realize automatic drug dispensing, since each transmission part has a lifting action, it is easy to cause the medicine cap to be jacked up, affecting work efficiency
