The function flows from the powder outlet 23 to between the tank body 1 and the grinding cylinder 2; since the filter screen 231 is installed in the powder outlet 23, the filter screen 231 can block the solid raw material, thereby ensuring the passage of the powdery raw material; During the rotation of the vane 24, when the vane 24 pushes the surrounding airflow into the grinding barrel 2, the air pressure above the vane 24 is reduced, so that the air between the milling barrel 2 and the tank body 1 flows toward the vane. 24 and the cover plate 11; at this time, the powder located between the grinding cylinder 2 and the tank body 1 is not blown upward by the air flow due to its own gravity; because the air flow in the tank body 1 reciprocates around the grinding cylinder 2 Swirling, so that the reciprocating airflow can drive the powder in the grinding cylinder 2 to between the grinding cylinder 2 and the tank body 1, so that the powder gathers between the grinding cylinder 2 and the tank body 1, and is located between the grinding cylinder 2 and the tank body 1. The stirring plate 22 between the tank body 1 will be driven by the grinding cylinder 2 to stir and mix the powder between the grinding cylinder 2 and the tank body 1. When the raw materials in the grinding cylinder 2 are ground and pulverized, the The electromagnetic valve 17 in the air port 16 and the circular groove 111 is opened, and the connecting pipe 151 of the vacuum conveying pump 15 is connected with the air outlet 16 first, so that the powder positioned between the grinding cylinder 2 and the tank body 1 is in the vacuum conveying pump 15. Under the adsorption, it is discharged from the air outlet 16, and the external air enters the tank body 1 through the circular groove 111, the communication groove 121 and the suction pipe 25, which not only ensures the stability of the air pressure inside the tank body 1, but also makes the external gas blow the grinding cylinder 2 The dust floating inside flows from the powder outlet 23 to between the grinding cylinder 2 and the tank body 1 and is sucked away by the vacuum conveying pump 15. When the powder between the grinding cylinder 2 and the tank body 1 is completely discharged, it will be vacuum conveyed The connecting pipe 151 of the pump 15 communicates with the circular groove 111, and drives the grinding cylinder 2 to rotate through the drive motor 14, so that the powder remaining at the bottom of the grinding cylinder 2 can pass through the communication groove 121 and the The circular groove 111 is discharged; thereby reducing the residue of powder in the grinding cylinder 2 and the tank body 1, reducing the waste of drug powder; and the collected mixed raw materials can be put into the grinding cylinder 2 again for grinding, and can also Pack and transport directly;

Wherein, as the grinding cylinder 2 rotates, the grinding cylinder 2 drives the stirring plate 22 to rotate, so that the stirring plate 22 is in rolling contact with the inner wall of the tank body 1 through the rollers 222 on the surface, so that the rollers 222 roll in the process of rotating. The column 222 can drive the rotating shaft 223 on the upper end of the stirring plate 22 to rotate through the helical gear set 228, so that the rotating shaft 223 drives the transmission belt 224 on the surface to circulate around the rotating shaft 223. During the rotation of the stirring plate 22, the lower end surface of the stirring plate 22 is in contact with the tank. The lower end surface of the tank body 1 is in sliding contact, so that the powder particles on the lower end surface of the tank body 1 are shoveled by the spiral groove and converge on the upper end surface of the stirring plate 22. After being conveyed to the upper end of the grinding cylinder 2, since the surface of the transmission belt 224 is provided with a sieve 225, the powder particles with a small particle size can directly fall from the sieve 225 to the bottom of the tank body 1, so that the powder can fall from the sieve 225 During the falling process, the powders can be mixed with each other by the blowing of the updraft, which improves the mixing uniformity of the powders, and the powder particles with large particle diameters are conveyed to the upper end of the grinding cylinder 2 by the transmission belt 224, so that the powder particles with large particle diameters The powder particles fall back to the grinding cylinder 2, so that the grinding wheel 21 in the grinding cylinder 2 will grind them again, so as to ensure that the particle size of the powder particles between the grinding cylinder 2 and the tank body 1 is small and uniform, And the setting of shovel plate 26 makes shovel plate 26 can shovel the raw material at the bottom of the rotating grinding cylinder 2, avoiding that the raw material is adhered and compacted at the bottom of grinding cylinder 2 under the rolling of grinding wheel 21, The raw materials compacted at the bottom of the grinding cylinder 2 can be separated from the grinding cylinder 2 under the action of the shovel plate 26 and effectively ground by the grinding wheel 21, thereby improving the grinding effect of the grinding wheel 21 on the raw materials in the grinding cylinder 2 ; and when the vacuum delivery pump 15 is connected with the air outlet 16, the control drive motor 14 rotates in reverse, and the grinding cylinder 2 drives the stirring plate 22 and the blade plate 24 to rotate in reverse, so that the outside of the grinding cylinder 2 enters from the communication groove 121 Part of the gas flows from the upper end of the grinding cylinder 2 to between the grinding cylinder 2 and the tank body 1 under the impetus of the blade plate 24, and the other part directly enters between the grinding cylinder 2 and the tank body 1 from the powder outlet 23. The shovel plate 26 shovels the powdery raw material at the bottom of the grinding cylinder 2 to prevent the raw material from adhering to the bottom of the grinding cylinder 2, and at this time the external gas is ejected from the air hole 261, so that the external gas can be blown directly through the air hole 261. The raw materials that are shoveled to the shovel plate 26 can improve the looseness of the raw materials on the one hand, and on the other hand, the raw materials can be quickly discharged from the powder outlet 23 with the air flow; The raw material will enter the vacuum delivery pump 15 under the suction of the air holes 261. By setting multiple groups of air holes 261, the adsorption range of the air holes 261 is increased, thereby accelerating the discharge speed of the raw materials in the grinding cylinder 2; During the process of the cover plate 11, the fixed column 122 will first enter the circular groove 111. At this time, the fixed column 122 is blocked by the bottom of the circular groove 111. At this time, the fixed column 122 is pushed by the cover plate 11 and moves downward, so that the telescopic column 123 compresses the connection spring 125 relative to the fixed column 122 and enters the groove 124 until the cover plate 11 is covered on the grinding cylinder 2. At this time, the telescopic column 123 is pushed by the restoring force of the connection spring 125 to produce a downward movement trend, so that The telescopic column 123 drives the grinding wheel 21 to press against the bottom of the grinding cylinder 2 through the connecting rod 13, thereby increasing the rolling pressure of the grinding wheel 21 on the raw material at the bottom of the grinding cylinder 2, thereby increasing the grinding effect of the grinding wheel 21 on the raw material , and through the setting of the straight rod 126, the straight rod 126 communicates with the communication groove 121 inside the fixed column 122 and the telescopic column 123, so that when the telescopic column 123 goes deep into the groove 124, the straight bar 126 moves with the telescopic column 123 and It is always in the communication groove 121 of the fixed column 122, so that when the vacuum delivery pump 15 communicates with the circular groove 111, the powder in the grinding cylinder 2 passes through the communication groove 121 and the straight rod 126 to cross the groove 124 to prevent the powder raw material from entering the groove 124, on the one hand, it prevents powder raw materials from accumulating in the groove 124 and prevents the telescopic column 123 from entering the groove 124, causing the fixed column 122 to fail to fully enter the tank body 1 and prevent the cover plate 11 from being tightly closed, thereby ensuring the normal use of the present invention. On the other hand, it prevents the powder raw material from deteriorating in the groove 124, thereby causing the degraded powder raw material to pass through the circular groove 111 and be sucked by the vacuum pump 15, causing other raw materials to be polluted; thereby improving the quality of raw material production; passing through the scraper 27 Set so that when the grinding wheel 21 rolls, the scraper 27 can scrape the rolling grinding wheel 21 surface, so that the scraper 27 will be squeezed by the grinding wheel 21 and adhere to the raw material on the grinding wheel 21 surface to scrape off, avoiding The raw material remains on the surface of the grinding wheel 21, and the scraper 27 is in sliding contact with the filter screen plate 231, so that when the filter screen plate 231 rotates to the scraper plate 27 with the grinding cylinder 2, the scraper plate 27 can not only be pushed close to the filter screen plate 231 The solid raw material is kept away from the filter screen plate 231 to prevent the raw material from covering the mesh of the filter screen plate 231, and the powder that is squeezed by the solid raw material and adhered to the surface of the filter screen plate 231 can be scraped off, so that the powder adhered to the filter screen plate 231 The powder on the surface can pass through the filter screen plate 231 and the powder outlet 23 to between the grinding cylinder 2 and the tank body 1 under the blowing of the airflow, and the setting of the impact block 233 makes the stirring plate 22 drive when the stirring plate 22 rotates. The blocking plate 226 on the surface rotates, so that when the blocking plate 226 rotates to the protrusion 18, the blocking plate 226 can be blocked by the protrusion 18 and rotate upwards, so that the upwardly rotating blocking plate can pull the impact block 233 to compress the fixed spring through the wire rope 227 234 is away from the filter screen plate 231, until the retaining piece 226 crosses the protrusion 18, the fixed spring 234 pushes the impact block 233 to reset, so that the impact block 233 impacts on the filter screen plate 231 under the action of inertia, so that the holes in the filter screen plate 231 gather The powder can break away from the filter screen plate 231 under the action of the vibration force, thereby ensuring the smoothness of the holes of the filter screen plate 231 and improving the ventilation effect of the filter screen plate 231.
