Dispensing bottle head, dispensing device and dispensing method for granular preparations

Abstract

The invention provides a dispensing bottle head, dispensing device and dispensing method for a granular preparations. The dispensing bottle head comprises an upper cover, a gear set, a lower cover anda connecting shaft. The upper cover is connected with a bottle opening. The connecting shaft connects the upper cover, the gear set and the lower cover together. The gear set can rotate around the connecting shaft. The upper cover and the lower cover do not rotate relative to the connecting shaft. The upper cover is provided with a feeding inlet. The lower cover is provided with a discharging outlet. The feeding inlet and the discharging outlet are arranged in a staggered mode. The gear set comprises a first gear and a second gear which are the same and is further provided with a first containing cavity, a second containing cavity and a third containing cavity. The two gears are controlled, so that the first containing cavity conveys granular preparations of a fixed volume from the feeding inlet to the discharging outlet. The second containing cavity and the third containing cavity are matched, and granular preparations of a set variable volume are conveyed from the feeding inlet to the discharging outlet. The dispensing bottle head can realize dispensing of granular preparations of the fixed volume and the variable volume, and accurate dispensing of a small quantity of preparations, can avoid influence on magnetic-sensitive preparations, and is small in volume and low in cost.

Description

technical field [0001] The invention relates to the technical field of dispensing granule preparations, and more specifically relates to a dispensing bottle head, a dispensing device and a dispensing method of traditional Chinese medicine granule preparations. Background technique [0002] In recent years, as the demand for traditional Chinese medicine formula granules has gradually expanded, the requirements for its production and dispensing have also gradually increased, and the realization of intelligence and automation is undoubtedly the choice for efficient production and dispensing of traditional Chinese medicine formula granules. The traditional Chinese medicine dispensing system can automate the dispensing of formula granules. It can implement automatic dispensing and monitor the whole process of the computer. Through the process of product name scanning, automatic calculation, automatic dispensing, and sealed packaging of the single dose of granules, accurate and rap...

AI Technical Summary

Problems solved by technology

The important part of automatic dispensing lies in the design of the dispensing bottle head, which is directly related to the accuracy and quality of the dispensing. In the prior art, the dispensing bottle head has direct drug dispensing, drawer type dispensing, and magnetic linear dispensing. , the existing dispensing bottle head has small dose dispensing accuracy that does not meet clinical requirements, or cannot realize the combination of constant volume dispensing and variable volume dispensing, or some magnetically sensitive traditional Chinese medicine particles cannot be dispensed due to the existence of magnetic force
