[0029] Working principle: When in use, the utility model puts the drug raw materials to be prepared into the granulation tube 3 through the feed trough 9. When the drug raw materials are put into the granulation tube 3, the main drive motor 22 is turned on by control. When the main drive motor 22 is turned on, it will drive the first pulley 23 to rotate. When the first pulley 23 rotates, it will drive the second pulley 24 to rotate through the transmission belt. When the second pulley 24 rotates, it will drive the reducer 2 to rotate. When the reducer 2 rotates, it will drive the spiral extrusion shaft 4 through the coupling. When the spiral extrusion shaft 4 rotates, the drug raw material inside the granulation tube 3 is pushed forward by the force generated by the rotation of the spiral blade on the outer curved surface of the spiral extrusion shaft 4. When the drug raw material inside the granulation tube 3 moves forward, the heater 10 is turned on by control. When the heater 10 is turned on, the heating copper tube 11 is heated. When the heating copper tube 11 is heated, the drying fan 12 is turned on by control. When the drying fan 12 is turned on, the heat generated by the heating copper tube 11 is blown upward, thereby pre-drying the drug raw material inside the granulation tube 3. After the drug raw materials inside the granulation hole 7 are pre-dried while moving forward, the drug raw materials will be preliminarily extruded through the extrusion hole plate 5. After the drug raw materials are preliminarily extruded through the extrusion hole plate 5, they will continue to enter the granulation hole 7 along the outer end of the extrusion cone 8 for secondary extrusion. After the drug raw materials are secondary extruded through the granulation hole 7, the auxiliary driving motor 15 is turned on by control. When the auxiliary driving motor 15 is turned on, it will drive the cutting knife frame 16 to rotate. When the cutting knife frame 16 rotates, it will drive the cutting blade 17 to cut the drug raw materials that have been secondary extruded through the granulation hole 7. The drug raw material is cut into granules at the front end outlet of the granulation hole 7, and the granules fall into the collecting bucket 21. When the granules fall into the collecting bucket 21, the discharge fan 19 is turned on by controlling. When the discharge fan 19 is turned on, the granules falling to the bottom of the collecting bucket 21 are finally blown and dried, and the granules are blown out along the discharge pipe 20, so that the drug granules are prepared and the drug raw material can be pre-dried before the preparation of the granules is completed.

[0030] At the same time, by rotating the loosening nut, when the fastening nut is loosened, by rotating the adjusting screw 18, when the adjusting screw 18 rotates, the adjusting screw 18 will move forward and backward due to the force generated by the threaded connection with the upper end of the auxiliary support frame 25. When the adjusting screw 18 moves forward and backward, it will drive the triangular mounting platform 14 to move forward and backward along the outer curved surface of the limiting slide bar 13. When the triangular mounting platform 14 moves forward and backward in a straight line, it will synchronously drive the cutting blade 17 to move forward and backward in a straight line. When the cutting blade 17 moves forward and backward in a straight line, the distance between the cutting blade 17 and the granulation hole 7 will become larger or smaller, thereby achieving the effect of facilitating the adjustment of the length of the medicine cut into granules.
