[0025] It should be noted that some common catalyst adding equipment is relatively simple in actual use, and cannot quantitatively add catalysts in different states well, and its use is relatively limited;

[0026] In this embodiment, when preparing medicines, the entire device is installed on the corresponding workstation. When it is necessary to add a liquid catalyst, the liquid catalyst is placed in the second storage space 102. First, the amount to be added is set by the controller. When it is necessary to add liquid catalyst, the second solenoid valve on the connecting pipe 5 is started by the controller, and then the controller starts the telescopic rod 2 to drive the piston 4 to move a certain distance, so that a certain amount of liquid catalyst is drawn into the metering barrel 3. Then the controller closes the second solenoid valve on the connecting pipe 5, and then opens the second solenoid valve on the discharge pipe 7. Then the controller starts the telescopic rod 2 again to drive the piston 4 to move downward, so that a certain amount of liquid catalyst is pumped into the discharge pipe 7 (the discharge pipe 7 is connected to the corresponding drug preparation equipment), thereby completing the automatic quantitative addition operation of the liquid catalyst.

[0027] When it is necessary to add granular or powdered catalysts, the amount to be added is set in advance through the controller, and the granular or powdered catalysts are placed in the first storage space 101. The first solenoid valve on the connecting pipe is opened by the controller to discharge the granular or powdered catalysts in the first storage space 101 into the weighing barrel 9. Under the action of the weighing frame 8, the weighing operation of the granular or powdered catalysts is completed. When the corresponding weight requirement is reached, the controller closes the first solenoid valve on the connecting pipe, and then opens the first solenoid valve on the discharge pipe 901 (the discharge pipe 901 is connected to the corresponding drug preparation equipment). At the same time, the controller starts the cleaning mechanism 10 to scrape the granular or powdered catalysts adhered to the inner wall of the weighing barrel 9, thereby improving the cleanliness of the discharge in the weighing barrel 9, thereby improving the accuracy of the catalyst discharge. During the entire operation, different forms of catalysts can be quantitatively added well, which better meets the addition requirements of different catalysts during drug preparation and is more flexible to use.

[0028] In a further preferred embodiment of the utility model, the cleaning mechanism 10 includes: a servo motor 1001 fixedly mounted on the outer wall of one side of the weighing barrel 9; a connecting shaft 1002 rotatably mounted on the weighing barrel 9, and one end of the connecting shaft 1002 is fixedly connected to the output shaft of the servo motor 1001; a vertical shaft 1003 rotatably mounted in the weighing barrel 9; a mounting shaft 1004 rotatably mounted on the weighing barrel 9; a cleaning brush 1005 fixedly mounted on the mounting shaft 1004, and the cleaning brush 1005 is in contact with the inner wall of the weighing barrel 9; four bevel gears 1006 fixedly mounted on the connecting shaft 1002, the vertical shaft 1003 and the mounting shaft 1004, respectively, and the four bevel gears 1006 are meshed with each other.

[0029] In this embodiment, when the cleaning mechanism 10 is used, the servo motor 1001 is started by the controller to drive the connecting shaft 1002 to rotate. Under the interaction of the vertical shaft 1003 and the bevel gear 1006, the cleaning brush 1005 on the mounting shaft 1004 is driven to rotate to scrape the granular or powdered catalyst adhered to the inner wall of the weighing barrel 9, thereby improving the cleanliness of the material discharged into the weighing barrel 9, thereby improving the accuracy of the catalyst discharge.

[0031] In this embodiment, when the servo motor 1001 rotates, the pulley 12 and the belt 13 interact with each other, thereby driving the material feeding rack 11 to rotate, thereby feeding the granular or powdered catalyst in the discharge pipe 901, thereby avoiding blockage in the discharge pipe 901 and increasing the material discharge speed.

[0035] In this embodiment, when it is necessary to feed the granular or powdered catalyst into the weighing bucket 9 for weighing, the controller starts the drive motor 14 and the stirring frame 15 to rotate, thereby stirring the granular or powdered catalyst in the first storage space 101, so that the granular or powdered catalyst can be quickly fed into the weighing bucket 9.

[0036] In a further preferred embodiment of the utility model, a second solenoid valve is provided on both the connecting pipe 5 and the feeding pipe 7 , and the second solenoid valve is used to control the connecting pipe 5 and the feeding pipe 7 .

[0037] In this embodiment, the second solenoid valve is used to facilitate the control operation of the connecting pipe 5 and the feeding pipe 7, thereby facilitating the metering operation of the liquid catalyst.
