Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically a continuous slicing device for traditional Chinese medicine decoction pieces based on automated control. Background Technology
[0002] Slicing Chinese medicinal herbs is one of the core processes in the processing of Chinese medicinal materials, especially for rhizomes, where the quality of the slices directly affects the dissolution of active ingredients and the efficiency of subsequent processing. Currently, most mainstream production equipment adopts an intermittent / batch operation mode, with a typical process: manual feeding → slicing → machine shutdown and unloading → equipment reset → reloading cycle. This mode has the following significant drawbacks: Production efficiency bottlenecks: Frequent equipment start-ups and shutdowns between processes result in over 30% of the time being wasted, severely limiting production capacity and making it difficult to meet the demands of large-scale production. High reliance on manual labor (e.g., adjusting the posture of medicinal materials, handling blockages) requires 2-3 operators per shift, with labor costs accounting for over 25% of total costs.
[0003] Quality inconsistency defects: The thickness of slices within a batch varies by ±0.5mm (e.g., when the thickness is set to 2mm, the actual output is 1.5-2.5mm), leading to uneven drying and differences in packaging filling. There is no real-time compensation mechanism for blade wear; after one hour of continuous processing, the slice pass rate decreases by 15%-20%.
[0004] Equipment operating losses: The motor starts and stops more than 200 times a day, the inrush current increases energy consumption by 18%, and shortens the life of mechanical transmission components by 30%.
[0005] Production line coordination obstacles: When connecting with continuous cleaning and drying equipment, a buffer hopper needs to be added. Material transfer leads to a 5% increase in the fragmentation rate and is prone to cross-contamination.
[0006] Therefore, there is an urgent need to develop an innovative device that can connect the entire chain of "continuous feeding → precise cutting → online quality inspection → adaptive control → continuous output" in order to break through the technical barriers to the continuous production of Chinese herbal medicine pieces.

The lower end of the conveyor belt 3 is rotatably connected to the drive shaft 402 along the conveying direction. One end of the drive shaft 402 is fixedly connected to the drive motor 401, which is fixedly connected to the conveyor belt 3. Two sets of worm gears 404 are fixedly connected to the drive shaft 402, each meshing with a worm 405. The worm 405 is fixedly connected to the transmission shaft 403, which is rotatably connected below the conveyor belt 3. Both ends of the transmission shaft 403 are connected to either a distributor 2 or a slicing mechanism 6, i.e., both ends of the transmission shaft 403 are fixedly connected to either a first rotating disk 106 or a second rotating disk 311. A vibrating screen 7 is installed at one end of the conveyor belt 3.
[0023] The working principle of this utility model is as follows: In use, firstly, the conveyor belt 3 and drive motor 401 are started. The drive motor 401 drives the drive shaft 402 to rotate. The drive shaft 402 drives two sets of transmission shafts 403 to rotate via worm gear 404 and worm 405 respectively. The transmission shafts 403 drive the first rotating disk 106 to rotate. The first rotating disk 106 drives the movable frame 104 to move up and down reciprocally via the first connecting rod 105. The movable frame 104 drives the movable plate 102 inside the slot plate 101 to move up and down reciprocally via the side guide rod 103. At this time, root and rhizome medicinal materials are placed into the feed hopper 1. The movable plate 102 moves up and down to make the length direction of the medicinal materials consistent with the conveying direction of the conveyor belt 3, and they fall from between the slot plates 101 into the conveying channel, and are conveyed by the conveyor belt on the conveyor belt 3. When passing through the pressing mechanism 5, the medicinal materials are squeezed between the rubber belt 204 and the conveyor belt. Under the action of the pressing spring 206, the wheel groove frame 202 applies downward pressure through the sliding guide rod 205, causing the rubber belt 204 to... 04. The herbs on the conveyor channel are pressed tightly. The pressed herbs continue to move forward with the conveyor belt 3 and enter the slicing mechanism 6. At this time, the second rotating disk 311 drives the operating rod 308 to move up and down reciprocally through the second linkage rod 310. When the operating rod 308 moves upward, the spiral spring 307 provides the reset power, which causes the operating block 304 to drive the slicing knife 303 to move upward. When the operating rod 308 moves downward, the buffer spring 309 applies force to the operating block 304, which causes the operating block 304 to drive the slicing knife 303 to move downward, thereby slicing the herbs on the conveyor belt 3. The buffer spring 309 provides a flexible pressure, which ensures that the blade can effectively cut the material rather than make a hard impact, even when cutting herbs of different hardness or size, thus protecting the blade and equipment. The sliced herbs fall from the end of the conveyor belt 3 onto the vibrating screen 7. The vibrating screen 7 separates the sliced herbs that meet the specifications from the debris, powder, etc., completing the preliminary cleaning process and directly obtaining high-quality sliced products.
[0024] In this invention, the conveying process of the conveyor belt 3 and the reciprocating motion of the slicing blade 303 need to be precisely coordinated. That is, an intermittent motion mechanism is used to enable the conveyor belt 3 to perform an intermittent motion of "one step (one slice thickness), then a stop." The moment the conveyor belt 3 stops, the slicing blade quickly drops to complete the slice, then lifts up, and the conveyor belt 3 then advances a fixed distance. This cycle is precisely controlled by a control system (such as a PLC or microcontroller) or a mechanical linkage device. Since this technology is mature, it will not be described in detail here.
[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
