At the same time, the servo motor 220 drives the stabilizer bar 214 to rotate synchronously through the second belt 219, ensuring that the action rhythm of the striking plate 213 and the agitator 215 is matched, so as to realize the continuous agitation and uniform crushing of the raw materials, and complete the stirring, crushing and precise collection of the powder.

[0039] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0040] [Second Embodiment] like Figure 11 As shown, the second embodiment of the present invention also provides a control method for a pharmaceutical powder raw material stirring and pulverizing device, comprising the following steps: S1: Feeding control of excipients and raw materials: The powder raw materials and excipients are fed in through the connector 43 of the feed pipe 42 in the excipient assembly 4, so that the powder raw materials and excipients enter the feed hopper 21 through the protective cover 41 and are initially mixed. The mixed material falls into the outer shell 23 of the processing chamber. S2: Material feeding and guiding control: Start the servo motor 220, drive the active rod 212 to drive the striking plate 213 to rotate periodically, so that the striking plate 213 continuously strikes the guide plate, and disperses the agglomerated material by rotating the agitator 215, while the arc-shaped guide plate 210 pushes the material towards the crushing roller 27 area. S3: Crushing control: Start the drive motor 22, which drives the crushing roller 27 to rotate via belt drive, and crushes the material pushed to the crushing roller 27 area by roller pressing and shearing. S4: Screening and receiving control: The receiving tray 31 is positioned by the cooperation of the limiting strip 315 of the receiving tray 31 and the limiting groove 314 of the stop bar 311, and the locking block 316 and the groove 313 of the protrusion 312. The crushed material falls into the receiving plate 34 through the discharge port 222. After sliding into the receiving tray 31 through the receiving plate 34, the material is guided to the screen plate 32 by the guide plate 33 to complete the screening of the material. S5: Material reprocessing: Pull the handle 310 upward to lift the screen plate 32 and add the unqualified material remaining on the top of the screen plate 32 back into the feed hopper 21 for further processing.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
