Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments.

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0040] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0041] like Figures 1 to 7 As shown, the embodiment of the utility model provides a device for finely grinding raw materials for pharmaceutical use, including a raw material mixing mechanism 1, a mixing material pipe 2, a first screw conveyor 3, a first grinding bin 4, an extrusion grinding mechanism 5, a second grinding bin 6, a high-pressure airflow generator 7, a discharge bin 8 and a stirring mechanism 9;

[0042] The raw material mixing mechanism 1 is connected to the first screw conveyor 3 through the mixing material pipe 2, and the raw material mixing mechanism 1 is used to mix a variety of drug raw materials to be refined and crushed; in this embodiment, the raw material mixing mechanism 1 can mix different batches of the same drug raw material, or mix different types of drug raw materials, so as to reduce the operation steps and improve production efficiency.

[0043] The first crushing bin 4 is arranged at the discharge end of the first screw conveyor 3, and the extrusion and grinding mechanism 5 is arranged in the first crushing bin 4. The extrusion and grinding mechanism 5 is used for extruding and crushing the drug raw materials transported by the first screw conveyor 3 to the first crushing bin 4; the extrusion and grinding mechanism 5 can preliminarily destroy and crush the structure of the drug raw materials through the extrusion effect.

[0044] like Figure 1 As shown, the second crushing bin 6 is a conical structure that is wide at the top and narrow at the bottom. The second crushing bin 6 has a feed port and an air inlet at the top. The feed port is connected to the bottom of the first crushing bin 4 to receive the squeezed and crushed drug raw materials. The high-pressure airflow generator 7 is arranged on the top of the air inlet to spray a high-pressure airflow for impacting the drug raw materials toward the inside of the second crushing bin 6 through the air inlet; the squeezed and crushed drug raw materials can enter the feed port of the second crushing bin 6 from the bottom of the first crushing bin 4 and move downward along the conical structure. The high-pressure airflow generator 7 can spray a high-pressure airflow into the inside of the second crushing bin 6 through the air inlet. These high-pressure airflows will collide with the drug raw materials in the second crushing bin 6, thereby generating a strong impact force. This impact force will cause the drug raw materials to collide and break, thereby crushing the drug raw materials into finer particles, effectively improving the crushing effect of the drug raw materials.

The rotation driving assembly 51 is connected to the movable grinding disc 53 to drive the second grinding rods 531 of the movable grinding disc 53 to rotate in the grinding channel 522. When the extrusion and grinding mechanism 5 is working, the drug raw materials can enter the material guide hole 520 through the first screw conveyor 3, and flow into the grinding channel 522 under the action of gravity. The drug raw materials are squeezed by the first grinding rod 521 and the second grinding rod 531 in the grinding channel 522, thereby achieving crushing and grinding to obtain refined drug raw materials with a certain particle size.
