[0002] In the production process of traditional Chinese medicine decoction pieces, processing is a key link to ensure the quality and efficacy of traditional Chinese medicine, which covers many important steps such as cleaning, softening, drying, pulverizing, and tabletting. As the primary process, cleaning directly affects subsequent operations and the quality of the final product. Therefore, efficient and precise cleaning equipment is crucial for the production of traditional Chinese medicine decoction pieces.

[0003] Currently, most of the common traditional Chinese medicine decoction piece cleaning equipment on the market uses a fixed-hardness brush or a fixed cleaning force method for cleaning. In actual operation, it is difficult for such equipment to balance the cleaning requirements of traditional Chinese medicine raw materials with different hardnesses. When cleaning raw materials with a higher hardness, due to the insufficient rigidity of the brush, it is impossible to effectively remove the dirt on the surface of the raw materials, resulting in incomplete cleaning; while when cleaning raw materials with a lower hardness, the fixed-hardness brush is prone to over-brushing the raw materials, damaging the organizational structure of the raw materials and affecting the quality of traditional Chinese medicine decoction pieces.

[0048] The outer wall of the transmission member 54 is provided with an adjusting member 55. The adjusting member 55 is used to adjust the rigidity of the brush 57, including a rotating disk 551. The inner sides of multiple rotating disks 551 are fixedly connected to the outer wall of the transmission rod 547 and rotate under the drive of the transmission rod 547. The inner arc-shaped grooves 552 therein guide the movement of the sliding columns 555; multiple arc-shaped grooves 552 are formed inside the rotating disk 551 to provide a movement track for the sliding columns 555, converting the rotation of the rotating disk 551 into the linear motion of the sliding columns 555 driving the sliders 554; multiple fixed disks 553 are fixedly connected to the inner wall of the cleaning roller 56, and the inner sides of the fixed disks 553 are rotatably connected to the outside of the transmission rod 547 to provide an installation base and movement guidance for the sliders 554; one side of the fixed disk 553 is slidably connected to multiple sliders 554, which move linearly under the drive of the sliding columns 555 and drive the inner support shafts 556 to move; the outer walls of the sliders 554 are fixedly connected to the sliding columns 555 and slide outside the arc-shaped grooves 552 to transmit the motion of the rotating disk 551 and drive the sliders 554 to move; the far ends of the sliders 554 are fixedly connected to inner support shafts 556, which are adapted to the shape of the inner side of the base of the brush bristles 571.

On the top of the box shell 51, multiple spray nozzles 59 are fixed to spray water on the traditional Chinese medicine raw materials, cooperating with the brush 57 to clean the raw materials and improving the cleaning effect.

[0050] A processing method based on traditional Chinese medicine decoction pieces, applicable to the above - mentioned processing equipment for traditional Chinese medicine decoction pieces, includes the following steps:

[0051] S1. Cleaning: Put the traditional Chinese medicine raw materials to be cleaned into the rough - washing box for preliminary cleaning, then put the washed raw materials into the grading sieve 4 for grading according to the material size, and the graded materials are respectively put into two fine - washing boxes 5. When the materials enter the fine - washing box 5 and contact the receiving part 52, due to the hardness and gravity of the materials, the pressing plate 533 in the receiving part 52 rotates downward, thereby driving the slider 554 in the adjusting part 55 to slide through the transmission part 54, driving the inner support shaft 556 to move outward into the inside of the brush hair 571 and expand the conical spring 572, thereby increasing the overall rigidity of the brush 57.

[0052] S2. Softening: Put the cleaned materials into the two cylinder cavities of the steam softening cylinder 6 respectively, so that the traditional Chinese medicine raw materials are softened by high - temperature steam first to facilitate subsequent crushing.

[0053] S3. Drying: After being softened, the two sizes of materials are transported to two parts in the drying box 7, and the moisture on the surface of the materials is carried out through the operation of the drying box 7 to facilitate subsequent grinding into powder.

[0054] S4. Forming into slices: Place the prepared raw material solid powder in the multi - layer mold in the tablet press 9 for preliminary pressing to make the powder preliminarily formed, and then transfer the preliminarily formed decoction pieces to the hot - pressing section for secondary hot - pressing forming under certain temperature and pressure.

[0055] Working principle: Put the raw materials of Chinese medicine to be cleaned into the rough washing tank 3, and the rough washing tank 3 performs preliminary cleaning on them to remove most of the mud and impurities on the surface. The raw materials after preliminary cleaning are transferred to the grading screen 4, and the grading screen 4 is started to screen according to the size of the raw materials. The larger raw materials are left in the upper layer, and the smaller raw materials fall into the lower layer. Put the raw materials of different levels into two fine washing boxes 5 respectively. The materials enter the fine washing box 5 and contact with the guide plate 522. Due to their own gravity, the guide plate 522 rotates downward along the axis of the fixed pile 521. The trigger member 53 works, and the contact head 531 is close to the surface of the material under the action of the compression spring 534. According to the hardness of the material, the trigger rod 532 is displaced, pushing the extrusion plate 533, and then squeezing the L-shaped transmission plate 542, so that the L-shaped transmission plate 542 rotates, so that its long side is lifted upward, thereby driving the rack plate 545 to move upward, so that the gear 546 rotates, and finally drives the rotating disk 551 to rotate through the transmission rod 547. And due to the guiding effect of the arc groove 552, the rotating disk 551 rotates to make the slide column 555 drive the slider 554 to slide outward, thereby driving the inner support shaft 556 to enter the brush 571 to open the conical spring 572, thereby enhancing the rigidity of the brush 57. At this time, the nozzle 59 sprays water, the driving member 58 drives the cleaning roller 56 to rotate, and the brush 57 cleans the raw material finely.

[0056] The cleaned materials are placed in the two barrel cavities of the steam softening cylinder 6 respectively, and the high-temperature steam is used to soften the Chinese medicine raw materials and reduce the hardness for subsequent crushing. The two softened materials of different sizes are respectively transferred to the two parts of the drying box 7. Then, the surface moisture of the materials is removed by heating and evaporation to prevent adhesion during subsequent grinding and ensure the crushing effect. The dried and proportioned raw material solid powder is then placed in the multi-layer mold of the tablet press 9, and is preliminarily pressed to make it preliminarily formed. Finally, the preliminarily formed pieces are transferred to the hot pressing section, and are hot-pressed for a second time at a specific temperature and pressure to obtain finished Chinese medicine pieces.

[0057] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
