Medicine storage tank of automatic traditional Chinese medicine dispensing machine

Abstract

The invention relates to a medicine storage tank of an automatic traditional Chinese medicine dispensing machine. The medicine storage tank comprises a tank body and a discharge device. The tank body is provided with a medicine inlet. The bottom of the tank body is provided with a medicine outlet. The discharge device comprises a motor and a roll shaft connected with an output shaft of the motor. The motor is connected with a servo controller. The roll shaft is arranged at the medicine outlet. The surface of the roll shaft is provided with a plurality of tooth blades. The outer ends of the tooth blades selectively abut against the inner wall of the medicine outlet. Airbags are arranged between the tooth blades. The outer surfaces of the airbags are partially pasted onto the surfaces of the tooth blades and the surface of the roll shaft. A ventilation channel is formed in the roll shaft and communicates with inlets of the airbags. One end of the roll shaft is provided with a valve and a ventilation rotary connector. The medicine storage tank has the following obvious advantages that the roll shaft and the tooth blades are of the same specifications; before use, the size of the space between the tooth blades is changed by regulating the size of the airbags so as to meet the requirement for different medicine amounts, and the trouble of manufacturing different specifications of roll shafts and tooth blades is avoided.

Description

technical field [0001] The invention relates to a traditional Chinese medicine storage tank, in particular to a medicine storage tank for automatically dispensing traditional Chinese medicine. Background technique [0002] The patent application with the application number 2016103127911 discloses an automatic traditional Chinese medicine dispensing machine.

The weighing device controls the rotation of the feeding motor to achieve the purpose of obtaining the appropriate amount of medicine. The disadvantage of this kind of storage tank is that differen...

AI Technical Summary

Problems solved by technology

The disadvantage of this kind of storage tank is that different traditional Chinese medicines are used in different amounts, and the requirements for the size of the teeth are different. If the rollers and teeth of different sizes are manufactured, it is inconvenient and inflexible to manufacture; the weight of the traditional Chinese medicine is applied to the rollers. In the upper part, the motor drives the roller to rotate, and it needs to overcome the gravity, which consumes more electricity
