[0027] A scraping strip 9 is provided on one side of the connecting shaft 7, and a stirring plate 10 is provided on the other side of the connecting shaft 7. The stirring plates 10 and the stirring blades 4 are arranged alternately, and the width of the stirring blades 4 is smaller than the width of the stirring plates 10, and the length of the stirring blades 4 is greater than the length of the stirring plates 10 (not shown in the figure); during the rotation of the stirring plates 10 and the stirring blades 4 of the present application, a mixing zone is formed between the two, and the scraping strips 9 are arranged in contact with the inner wall of the preparation bin 1. During the rotation of the connecting shaft 7, the medicine adhered to the inner wall of the preparation bin 1 is cleaned, mixed and prepared, thereby ensuring the efficacy of the prepared medicine. The main drive motor 2 and the auxiliary drive motor 5 described in the present application are both equipped with a frequency converter, and the speed ratio of the main drive motor 2 and the auxiliary drive motor 5 is set to 1.4-1.7:1-1.35 by operating the controller.

[0033] Control group 1 The difference between the control group 1 and the embodiment 1 is that the scraping strips 9 and the stirring plates 10 are both in the shape of straight plates. The same batch of drugs with the same dosage are prepared. During the preparation of the drugs, the prepared drugs of the control group 1 and the embodiment 1 are sampled and compared every 30 seconds. The seventh round of sampling and detection observations show that the drug molecules prepared in the embodiment 1 are mixed evenly with each other, while the drug molecules prepared in the control group 1 are dispersed in small groups; the eighth round of sampling and detection observations show that the drug molecules prepared in the embodiment 1 are mixed evenly with each other, while the drug molecules prepared in the control group 1 are scattered; continue to compare the control group The tenth sampling and testing observation of the medicine prepared in group one showed that the prepared medicine molecules were mixed evenly with each other, and the eleventh sampling and testing observation of the medicine prepared in control group one showed that the prepared medicine molecules were mixed relatively evenly with each other; the twelfth sampling and testing observation of the medicine prepared in control group one showed that the prepared medicine molecules were mixed evenly with each other; through experimental comparison, it was found that the setting of the scraping strip 9 and the stirring plate 10 in this embodiment one is relative to the setting of the scraping strip 9 and the stirring plate 10 in the control group one, which can improve the efficiency and quality of medicine preparation and mixing in the preparation bin 1.

[0034] Control group 2 The difference between the control group 2 and the embodiment 4 is that a stirring blade 4 is provided in the preparation bin 1 of the control group 2, and the end of the stirring blade 4 is arranged in contact with the inner wall of the preparation bin 1, and a heating component is provided on the stirring blade 4 and the heating component rotates with the stirring blade 4; through experimental comparison, it is concluded that the heating component in the control group 2 can perform mobile temperature control on the medicine in the preparation bin 1, and the stirring blade 4 in the preparation bin 1 is stirred alternately in the forward and reverse directions, so that the mixing stability of the medicine components prepared by it is reduced by 8% compared with the mixing stability of the medicine components prepared in the embodiment 4, and the time used for preparing the medicine is increased by more than 5% compared with the time used for preparing the medicine in the embodiment 4.

[0036] The present application sets the main drive motor 2 and the auxiliary drive motor 5 to mix and prepare the medicine at a speed ratio of 1.65:1.25 by operating the controller. The main drive motor 2 and the auxiliary drive respectively drive the stirring blade 4 and the scraping strip plate 9 and the stirring plate 10 to rotate in opposite directions, which can perform multi-level stirring and mixing on the medicine in the preparation bin 1, so that the ingredients of the prepared medicine can be fully integrated, improve the quality of drug mixing, so that the prepared medicine has a stable concentration and uniformity, which can further improve the drug efficacy of the medicine prepared by the medicine dispenser of the present application and reduce the risk of disease. The present invention can effectively solve the problem that in the existing medicine dispenser, the stirring blade 4 is usually driven by a motor to stir the medicine alternately in a clockwise and counterclockwise direction during the preparation process, which makes the collision effect between the prepared medicine molecules poor, and easily leads to low medicine preparation efficiency. The medicine near the outer diameter of the stirring circle of the stirring blade 4 is easy to adhere to the inner wall of the preparation equipment under the stirring action, resulting in uneven medicine concentration, causing the efficacy to be reduced, and it is difficult to achieve the accuracy of the medicine preparation and medication efficacy. This may not only reduce the therapeutic effect of the medicine, but also increase the risk of medicine use for patients.
