[0022] Please see Figure 4 - Figure 5 The first granulation component 32 includes a first granulation plate 321 for preparing drug granules. A first connecting plate 322 is fixedly connected to the top of the left and right sides of the first granulation plate 321 for connecting to the mounting rod 31. A first fixing plate 323 is fixedly connected to the front side of the first connecting plate 322 for mounting the first granulation component 32. Bolts are movably connected between the first granulation component 32 and the mounting rod 31.

[0023] Furthermore, the second granulation component 33 includes a second granulation plate 331 for assisting in the preparation of drug granules. Second connecting plates 332 are fixed to the top of both the left and right sides of the second granulation plate 331 for connection with connecting rods 334. A second fixing plate 333 is fixedly connected to the front of the second connecting plate 332 for fixing with the connecting rods 334. Connecting rods 334 are provided on both the left and right sides of the second granulation plate 331. A second mounting groove 336 is provided on the side of the connecting rod 334 closest to the second granulation plate 331 for connection with the second connecting plate 332. The second connecting plate 332 and... The movable connection includes a second fixing groove 335 at the front of the second mounting groove 336, which is used to connect with the second fixing plate 333. The second fixing plate 333 is movably connected to it. The second fixing plate 333 and the connecting rod 334 are movably connected by bolts. The middle of the connecting rod 334 on the right side is threaded with a screw 337, which is used to adjust the position of the second granulation plate 331, thereby changing the position of its granulation hole 34. The middle of the connecting rod 334 on the left side is slidably connected with an auxiliary rod 338, which is used to assist in the position of the second granulation plate 331.

[0024] Furthermore, both the first granulation plate 321 and the second granulation plate 331 are provided with multiple granulation holes 34 for preparing drug granules. The granulation holes 34 on the two granulation plates are the same size, number, and position. The second granulation plate 331 is in close contact with the first granulation plate 321.

[0025] Specifically, a mounting groove 311 is provided on the side of the mounting rod 31 near the first granulation component 32 for connecting the first connecting plate 322. The first connecting plate 322 is movably connected to it. A fixing groove 312 is provided at the front of the mounting groove 311 for installing the first fixing plate 323. The first fixing plate 323 is movably connected to it. A sliding groove 313 is provided at the lower part of the mounting groove 311 for connecting the connecting rod 334. The connecting rod 334 is slidably connected to it. An auxiliary rod 338 passes through the mounting rod 31 on the left side and is fixedly connected to it. A screw 337 passes through the mounting rod 31 on the right side and is rotatably connected to it, for adjusting the position of the second granulation plate 331.

[0026] Working principle: In use, the material is poured into the outer shell 1 through the top of the outer shell 1. The motor 22 is turned on, and the motor 22 will drive the rotating shaft 21 connected to it to rotate. When the rotating shaft 21 rotates, the gear 25 connected to it will rotate, and drive the lower gear 25 that meshes with it to rotate. The lower gear 25 will then drive the rotating shaft 21 connected to it to rotate in the opposite direction. When the rotating shaft 21 rotates, the mounting plate 23 connected to it will rotate. The mounting plate 23 will further drive the dispersing roller 24 connected to it to rotate, dispersing the clump of material entering the outer shell 1. The dispersed material will fall onto the granulation component 3. When the mounting plate 23 located at the bottom rotates, the dispersing roller 24 connected to it can fit with the first granulation plate 321, thereby extruding the material through the granulation hole 34 to complete the preparation of the medicine granules.

[0027] When it is necessary to adjust the size of the drug granules, rotate the screw 337 to move the connecting rod 334 connected to it forward. The second granulation plate 331, which is connected to it through the second connecting plate 332, will also move forward and drive the connecting rod 334 on the other side to slide along the auxiliary rod 338. This will cause the granulation holes 34 on the second granulation plate 331 to be misaligned with the granulation holes 34 on the first granulation plate 321. The gap of the second granulation plate 331 will block part of the granulation holes 34 on the first granulation plate 321, thereby changing the size of the discharge area of ​​the granulation holes 34.

[0028] When it is necessary to replace, repair, or clean the pelletizing part, unscrew the bolt between the first fixing plate 323 and the mounting rod 31 to remove the first pelletizing part 32. Then loosen the bolt between the second fixing plate 333 and the connecting rod 334 to remove the second pelletizing plate 331. Replacement or cleaning / repair can then be performed. During installation, insert the first connecting plate 322 into the first mounting groove 311, so that the first fixing plate 323 is inserted into the first fixing groove 312. Then fix the first pelletizing part 32 to the mounting rod 31 with bolts. Then insert the second connecting plate 332 into the second mounting groove 336, so that the second fixing plate 333 is inserted into the second fixing groove 335. Finally, connect the second fixing plate 333 to the connecting rod 334 with bolts.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
