[0066] Working principle: The traditional Chinese medicine is fed into the traditional Chinese medicine mixing and preparation device 2 along the feed pipe 21 through the feed port 211. The driving motor 22 is started to automatically control the rotation of the first drive shaft 221 and the drive wheel 222. The rotation of the drive wheel 222 drives the rotation of the runner 25 through the transmission belt 24, thereby driving the stable rotation of the shaft rod 26, and the extrusion and conveying spiral knife 261 conveys the traditional Chinese medicine to the right.

[0067] At the same time, the first motors 3463 of the upper particle size adjustment mechanism 3 and the lower particle size adjustment mechanism 4 are started to automatically control the rotation of the first lead screw 3461 and the second lead screw 3462. Through the action of the thread, the sliding cylinder 3492 and the first slider 3491 are driven to slide, driving the moving plate 348, the convex plate 3481 and the clamping block 3482 to move the first particle size adjustment limit plate 341, the second particle size adjustment limit plate 342 or the third particle size adjustment limit plate 343 horizontally for adjustment, and making it correspond to the right end of the traditional Chinese medicine mixing and preparation device 2 as required.

[0068] The electric push rod device 347 is started to automatically control the telescopic adjustment of the push rod 3471, so that the first particle size adjustment limit plate 341, the second particle size adjustment limit plate 342 or the third particle size adjustment limit plate 343 is adjusted longitudinally, and the concave hole 344 is butted against the shaft collar 292 to limit and block the right end of the traditional Chinese medicine mixing and preparation device 2.

[0069] The traditional Chinese medicine material is extruded through the particle holes 345 and then granulated by the rotation and cutting of the cutting blade 29.

[0070] At the same time, the second motor 529 of the moving adjustment structure 52 is started to automatically control the second drive shaft 5291 and the drive shaft disk 528. The drive shaft disk 528 drives the driven shaft disk 527 through belt transmission, so that the third lead screw 524 rotates to control the lateral sliding of the second slider 525 and the support column 526 through the action of the thread, and further makes the discharge plate 51 move to the left end, corresponding to the lower part of the right end of the first particle size adjustment limit plate 341, the second particle size adjustment limit plate 342 or the third particle size adjustment limit plate 343, so as to stably output the traditional Chinese medicine particles.

Their structures and principles can all be learned by those skilled in the art through technical manuals or through conventional experimental methods. The problem solved by the present invention is that traditional traditional Chinese medicine granulation equipment can only produce traditional Chinese medicine of the same particle size in a single way, and cannot quickly produce traditional Chinese medicine of different particle sizes according to requirements. When adjusting the particle size, it is necessary to stop the machine to replace parts, resulting in low efficiency and poor discharge accuracy. Through the mutual combination of the above parts of the present invention, by arranging the extrusion and conveying spiral knife 261 and the pelletizing blade 29 inside and at the right end of the traditional Chinese medicine mixing and preparation device 2, the traditional Chinese medicine directly enters the rotating cutting area after being formed by spiral extrusion, avoiding the adhesion problem caused by the cooling of traditional Chinese medicine in the traditional process, facilitating the extrusion and pushing of the mixed traditional Chinese medicine to the right end for rotating cutting and discharging. By arranging the upper particle size adjusting mechanism 3 and the lower particle size adjusting mechanism 4 above and below between the right end of the traditional Chinese medicine mixing and preparation device 2 and the pelletizing blade 29, through mechanical linkage and position closed-loop control, a dynamically adaptable particle size screening channel is formed. The upper particle size adjusting mechanism 3 and the lower particle size adjusting mechanism 4 quickly switch the particle size adjusting limit plates of different particle sizes through horizontal movement, and at the same time, through the relative movement up and down, a hierarchical screening flow channel is constructed to realize the output of traditional Chinese medicine with different particle sizes, breaking through the technical bottleneck of the rigid particle size adjustment of traditional granulation equipment and avoiding the cumbersome operation of replacing traditional mesh plates. By arranging the discharge positioning mechanism 5 on the right side of the traditional Chinese medicine mixing and preparation device 2, it is convenient to automatically control the discharge positioning mechanism 5 to move horizontally and position it at the outlet end of the traditional Chinese medicine mixing and preparation device 2.The rapid output after cutting traditional Chinese medicine into granules is realized.
