Spiral dosing mechanism and dosing method thereof

Abstract

The invention discloses a spiral dosing mechanism. The spiral dosing mechanism comprises thrust ball bearings, a bearing clamping spring, a dosing screw rod, a motor rotating shaft, a screw rod supporting plate and a dosing part, wherein the dosing screw rod is composed of a screw rod gear and a screw rod shaft; the motor rotating shaft is composed of a rotation shaft gear and a motor shaft; the motor shaft is connected to the motor, the other end is connected to the rotation shaft gear; a round hole A is arranged in the middle of the screw rod supporting plate; a round hole B is arranged at periphery of the round hole A center, the thrust ball bearings are arranged at upper and lower parts of the round hole A, one thrust ball bearing is arranged on the round hole B; the thread is arranged at the cover mouth of the dosing part, the cover bottom is provided with a shaft hole, the lower surface of the shaft hole is provided with the thrust ball bearings, and the shaft hole is provided with a dosing hole in the center. A dosing method comprises the following steps: the spiral dosing mechanism is arranged on a medicine bottle; and the motor rotating shaft rotates to drive the dosing screw rod so as to lead medicine powder to outflow through a spiral medicine groove and further finish medicine outflow. According to the spiral dosing mechanism, the structure is simple, the use is convenient, the installation is convenient, and the automatic dosing mechanism is used for metering and division of dosage, has good insulation from the outside, and can play a good role in preventing dust, air leakage and medicine leakage.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a screw dispensing mechanism, and also relates to a drug dispensing method of the screw dispensing mechanism. Background technique [0002] my country's traditional Chinese medicine culture has a long history and rich resources of traditional Chinese medicine. 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 fever" has become popular internationally. However, at present, China only accounts for a small part of the export volume of traditional Chinese medicines in the world. The main reason is that my country still adopts the traditional dispensing methods of crude crude drugs and hand grasping and weighing, and it is difficult to avoid drug crossover in the process of dispensing traditional Chinese medicines. Unfavorable factors such as po...

But 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 still adopts the traditional method of dispensing raw crude drugs and grasping and weighing by hand. Pollution and other unfavorable factors, and the speed is slow, the measurement error is large, and it is difficult to connect with the standardized, standardized and scientific international market of dispensing
