Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine decoction piece processing technology, specifically to a traditional Chinese medicine decoction piece processing device. Background Technology

[0002] In the processing of traditional Chinese medicine (TCM) decoction pieces, sun-drying is a crucial and time-consuming step. Traditional TCM sun-drying relies mainly on open-air drying yards or fixed drying racks. Open-air drying yards are greatly affected by weather, easily exposed to rain, pests, and dust contamination, and require a large area, making management inconvenient. While fixed drying racks can mitigate weather risks to some extent, their drying area is fixed, resulting in wasted space when the quantity of herbs is small, and requiring frequent relocation or additional equipment when the quantity is large, lacking flexibility. Furthermore, whether sun-drying is done outdoors or indoors, spreading and turning the herbs requires manual operation, which is labor-intensive, inefficient, and uneven turning can lead to uneven drying, affecting the quality of the decoction pieces. Additionally, the stagnant air environment during the drying process prolongs the drying cycle and easily accumulates dust on the surface of the herbs, causing secondary contamination.

[0003] Therefore, there is an urgent need in this field for a Chinese herbal medicine processing device that can flexibly adjust the drying area, integrate automatic spreading and turning functions, and actively promote air circulation and dust prevention, so as to improve drying efficiency, ensure the hygienic quality of the herbs, reduce labor intensity and save space. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a traditional Chinese medicine decoction piece processing device, which solves the problems mentioned above.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a Chinese herbal medicine processing device, comprising a support and a fixed drying tray fixed above the support, wherein a fixed cylinder is fixedly connected to the surface of the support, and a support rod is rotatably connected to both sides of the fixed cylinder, and both support rods are fixedly connected to the side of the fixed drying tray through a movable drying cloth, wherein the movable drying cloth is flush with the side of the fixed drying tray; The inner cavity of the fixed cylinder is rotatably connected to a fan driven by a motor. Multiple air outlets facing the medicinal herbs are opened on the outer surface of the fixed cylinder surrounding the fan. A filter screen is fixedly connected to the top of the fixed cylinder, and a comb plate driven by a motor is rotatably connected to the surface of the fixed cylinder. In use, the cylinder is first unfolded, and the two support rods are rotated and brought together. At this time, the positioning pin is inserted into the positioning hole for positioning. The movable drying cloth is then fully unfolded, forming a complete circle with the fixed drying tray for laying and drying the medicinal herbs. After the movable drying cloth is unfolded... At this point, with no obstruction on the side, the herbs are prone to falling. Slide the curved limit bar to move it to the side of the movable drying cloth to cover the top and prevent the herbs from falling. Place the herbs on top of the fixed drying tray, then start the motor to drive the comb plate to rotate, pushing the herbs to spread flat on the fixed drying tray and the movable drying cloth. The comb plate rotates intermittently in both directions to turn the herbs over and ensure the drying effect. The motor also drives the fan to rotate, blowing air through the air outlet of the fixed cylinder to assist in the drying of the herbs. This accelerates airflow and blows away floating dust, preventing dust from settling on the herbs.

[0006] As a further aspect of the present invention: the two support rods are connected on their adjacent sides by a snap-fit ​​assembly. The snap-fit ​​assembly includes a positioning pin that fixes the side of the left support rod and a positioning hole that is opened in the inner cavity of the right support rod and is adapted to the positioning pin. When the two support rods are rotated and brought together, the positioning pin is inserted into the positioning hole to position them. At this time, the movable drying cloth is fully spread out and forms a complete circle with the fixed drying tray to lay and dry the medicinal materials.

[0007] As a further aspect of the present invention: a fixed frame is fixedly connected to the side of the fixed drying tray, and an arc-shaped limiting rod is slidably connected to the inner cavity of the fixed frame. When the movable drying cloth is unfolded during use, the side is unobstructed, and the medicinal materials are prone to fall. The arc-shaped limiting rod is slid to the side of the movable drying cloth to block the top and prevent the medicinal materials from falling.

[0008] As a further aspect of the present invention: the bracket is a semi-circular frame and has a built-in counterweight to prevent tipping.

[0009] As a further aspect of the present invention: the inner cavity of the bracket is rotatably connected to an embedded top rod. When the movable drying cloth is unfolded, it may sag under the weight of the medicinal materials. Rotating the top rod will support it under the movable drying cloth, thus providing reinforcement.

[0010] Compared with the prior art, the present invention has the following advantages: This system achieves flexible expansion and efficient storage of the drying area: The combination of the expandable drying cloth and the fixed drying tray solves the problem of low utilization of fixed drying equipment. When a large amount of drying is needed, rotating the two support rods and locking them with the snap-fit ​​assembly allows the movable drying cloth to be fully expanded, forming a complete large-area circular drying surface together with the fixed drying tray. After drying is complete, releasing the snap-fit ​​and retracting the support rods restores the device to its compact state, greatly saving storage and operating space and achieving the flexibility of "one machine for two uses".

[0011] It provides automated functions for spreading and turning the medicinal materials, ensuring uniform drying: The spread and turning of the medicinal materials are automated through a motor-driven comb. During the spreading stage, the rotating comb evenly spreads the stacked medicinal materials across the entire drying surface. During the drying process, the control system can periodically drive the comb to rotate intermittently in both directions, gently and evenly turning the medicinal materials so that all sides can fully contact the air and airflow, ensuring uniform and thorough drying. This significantly improves the quality of the processed medicinal materials and completely replaces the heavy manual turning work.

[0012] Integrating an active ventilation and dust removal system, this system improves drying efficiency and hygiene. A fan inside the fixed cylinder generates directional airflow, which is directed towards the herbs on the drying surface through surrounding air outlets. This design not only accelerates airflow over the herbs, effectively shortening drying time, but also blows away lightweight debris, dust, and any dust that may fall from the herbs from the drying area. Combined with the top filter, this creates a relatively clean drying microenvironment, effectively ensuring the hygienic quality of the processed herbs.

[0013] Featuring comprehensive anti-fall and structural reinforcement designs, ensuring safe and reliable use: Addressing the issue of unobstructed edges on the unfolded drying cloth, a sliding, arc-shaped limiting rod is installed. This rod quickly moves to the edge after unfolding, forming an effective barrier to prevent herbs from falling during handling or wind. Simultaneously, a rotatable top rod provides bottom support for the unfolded drying cloth, preventing it from sagging, deforming, or even being damaged under load, ensuring the structural stability and lifespan of the device under full load.

[0016] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0017] Please see Figure 1-5 The present invention provides a technical solution: a Chinese herbal medicine processing device includes a support 1 and a fixed drying tray 2 fixed above the support 1. A fixed cylinder 3 is fixedly connected to the surface of the support 1. Support rods 8 are rotatably connected to both sides of the fixed cylinder 3. Both support rods 8 are fixedly connected to the side of the fixed drying tray 2 through a movable drying cloth 9. The movable drying cloth 9 is flush with the side of the fixed drying tray 2. A fan 5 driven by a motor is rotatably connected to the inner cavity of the fixed cylinder 3. Multiple air outlets 6 facing the medicinal materials are opened on the outer surface of the fixed cylinder 3 surrounding the fan 5. A filter screen 4 is fixedly connected to the top of the fixed cylinder 3, and a comb plate 7 driven by a motor is rotatably connected to the surface of the fixed cylinder 3. In use, the cylinder is first unfolded, and the two support rods 8 are rotated and brought together. At this time, the positioning pin is inserted into the positioning hole for positioning. Then, the movable drying cloth 9 is fully unfolded, forming a complete circle with the fixed drying tray 2 for laying and drying the medicinal materials. After the movable drying cloth 9 is unfolded, at this time... With no side obstruction, the medicinal herbs are prone to falling. The sliding arc-shaped limiting rod 13 is moved to the side of the movable drying cloth 9 to cover the top and prevent the herbs from falling. The herbs are then placed on top of the fixed drying tray 2. The motor is then started to drive the comb plate 7 to rotate, pushing the herbs to spread flat on top of the fixed drying tray 2 and the movable drying cloth 9. The comb plate rotates intermittently in both directions to turn the herbs over and ensure the drying effect. The motor drives the fan 5 to rotate, blowing air through the air outlet 6 of the fixed cylinder 3 to assist in the drying of the herbs. This accelerates airflow and blows away floating dust, preventing dust from settling on the herbs.

[0018] As a further aspect of the present invention: the two support rods 8 are connected on their adjacent sides by a snap-fit ​​assembly 11. The snap-fit ​​assembly 11 includes a positioning pin that fixes the side of the left support rod 8 and a positioning hole that is opened in the inner cavity of the right support rod 8 and matches the positioning pin. When the two support rods 8 are rotated and brought together, the positioning pin is inserted into the positioning hole to position them. At this time, the movable drying cloth 9 is fully spread out and forms a complete circle with the fixed drying tray 2 to lay and dry the medicinal materials.

[0019] As a further aspect of the present invention: a fixed frame 12 is fixedly connected to the side of the fixed drying tray 2, and an arc-shaped limiting rod 13 is slidably connected to the inner cavity of the fixed frame 12. When the movable drying cloth 9 is unfolded during use, the side is unobstructed, and the medicinal materials are easy to fall. The arc-shaped limiting rod 13 is slid and moved to the side of the movable drying cloth 9 to block the top and prevent the medicinal materials from falling.

[0020] As a further aspect of the present invention: the bracket 1 is a semi-circular frame and has a built-in counterweight to prevent tipping.

[0021] As a further aspect of the present invention: the inner cavity of the support 1 is rotatably connected to an embedded top rod 10. When the movable drying cloth 9 is unfolded, it may sink under the weight of the medicinal materials. Rotating the top rod 10 will support it under the movable drying cloth 9, thus providing a reinforcing effect.

[0022] Phase 1: Equipment Deployment and Preparation First, rotate the two support rods 8 outward from their retracted state until they are close together. At this time, the positioning pin on the left support rod 8, under inertia or slight pushing, inserts into the positioning hole of the right support rod 8, and is automatically locked by the snap-fit ​​assembly 11. As the support rods 8 unfold, the movable drying cloth 9 connected to them is fully stretched and flattened, forming a complete circular drying surface together with the fixed drying tray 2. Then, manually slide the arc-shaped limiting rod 13 inside the fixing frame 12, so that its arc-shaped part moves above the outer edge of the unfolded movable drying cloth 9, forming a fall-prevention guardrail. Finally, rotate the top rod 10 inside the bracket 1 cavity so that it extends and supports the bottom center area of ​​the movable drying cloth 9, enhancing the load-bearing structure.

[0023] Phase Two: Placement and Automatic Spreading of Medicinal Herbs Place the raw Chinese medicinal herbs to be dried in the center of the fixed drying tray 2. Start the motor that drives the comb plate 7. The motor drives the comb plate 7 to rotate continuously in one direction. The comb teeth gently and evenly push the central pile of herbs outwards until the herbs are spread evenly on the circular drying surface formed by the fixed drying tray 2 and the movable drying cloth 9, forming a layer of herbs of uniform thickness.

[0024] Phase 3: Active drying and intermittent turning After the medicinal herbs are spread out, the motor driving the fan 5 is turned on. The fan 5 rotates, generating airflow. After passing through the filter screen 4, the airflow is blown out from multiple air outlets 6 around the fixed cylinder 3, acting on the herbs from top to bottom or diagonally across the entire drying surface, accelerating moisture evaporation and blowing away dust. Simultaneously, the control system sets the drive motor of the comb plate 7 to enter intermittent operation mode, automatically performing a brief forward and reverse rotation every certain period, such as 30 minutes. Each rotation causes the comb teeth of the comb plate 7 to slightly flip the herbs, exchanging the positions of the upper and lower layers, thus achieving uniform drying.

[0025] Phase Four: Organizing and Putting Things Back in Their Place After the medicinal materials are dried, first stop the fan 5 and the comb plate 7. Rotate the top rod 10 back into the inner cavity of the bracket 1 for storage. Place the sliding arc-shaped limiting rod 13 back into its original position on the fixed frame 12. Then, release the locking mechanism of the snap-fit ​​assembly 11 by pressing or flicking the release mechanism, and rotate the two support rods 8 inward to fold them together. During the folding process, the movable drying cloth 9 folds accordingly, and the device finally returns to a compact state with minimal space occupation, making it easy to transfer or store. The dried medicinal materials can be collected directly from the fixed drying tray 2.
