[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 2. The present invention realizes precise control of the medicines entering the crushing equipment by setting a rotating wheel structure. The rotation of the rotating wheel can deliver the medicines into the crushing chamber according to the preset amount and at a fixed time, avoiding insufficient crushing or overloading of the crusher caused by excessive one-time input of medicines, and ensuring the continuity and stability of the crushing process. At the same time, through the setting of the collecting barrel, when the internal pressure of the crushing equipment reaches the preset threshold, the leakage hole can be temporarily closed and the input of medicines can be suspended until the medicines in the crushing chamber are fully processed and the pressure is released, ensuring the maximization of the medicine crushing process and avoiding poor crushing effect or equipment damage caused by excessive backlog.
[0013] 3. The present invention provides an electrostatic adsorption magnetic ring, which can effectively adsorb fine dust and mixed iron debris generated during the crushing process by utilizing the electrostatic field generated by the electrostatic adsorption magnetic ring when the medicine is continuously crushed by multiple groups of crushing knives. This electrostatic adsorption mechanism not only has a wide range of action and high adsorption efficiency, but also can effectively prevent dust and iron debris from re-mixing into the medicine, ensuring the purity and safety of the medicine after crushing.

[0030] Among them, by starting the active motor 41, the active motor 41 drives the rotating drum 44 to rotate, and the rotating drum 44 drives the crushing knife 46 to rotate. At this time, the crushing knife 46 can crush the medicines inside the crushing equipment, and by starting the first auxiliary motor 42 inside the rotating drum 44, the first auxiliary motor 42 drives the multi-section rotating plate 45 to rotate, and the multi-section rotating plate 45 drives the crushing knife 46 to move inside the rotating drum 44. In this way, by introducing two groups of alternately retractable crushing knives 46 structures, the rotation use of the crushing knives 46 is realized, the load of a single tool is effectively dispersed, the fatigue strength of the tool is significantly reduced, and the service life of the tool is extended.
[0031] In some embodiments, the cross-section of the crushing knife 46 is arc-shaped, a grinding block 461 is embedded in the rotating drum 44 near the crushing knife 46 , and the blade of the crushing knife 46 slides inside the grinding block 461 .
[0032] Among them, the crushing knife 46 is designed to be arc-shaped, which not only enhances the crushing ability of the tool, but also can drive the material to turn synchronously during the crushing process, effectively avoiding material accumulation and the formation of "dead corners". At the same time, the grinding block 461 can intermittently grind the edge of the crushing knife 46, so that the crushing knife 46 maintains the blade, thereby improving the crushing efficiency of the medicine.
[0033] In some embodiments, a cutting assembly 48 is disposed on the outer surface of the rotating drum 44 , and the cutting assembly 48 includes a support plate 481 and a cutter 482 .

[0034] The cutting knife 482 can further break the medicines that are difficult to break at the top of the filter plate 47 , thereby ensuring that the medicines can be stably broken and introduced into the interior of the filter plate 47 .

At this time, the scraper 52 is driven to rotate by the active motor 41, and the scraper 52 can scrape the iron chips adsorbed on the inner wall of the electrostatic adsorption magnetic ring 51 to the surface of the rubber plate 53, until it passes through the magnet block and activated carbon block on the inner bottom wall of the collection box 54 to adsorb impurities and odors, thereby ensuring the purity and safety of the medicine after crushing.
