[0015] A method for drying traditional Chinese medicine herbs, using the intelligent drying equipment for traditional Chinese medicine herbs as described above, includes the following steps: Step 100: Using manual labor or robotic arms, place the cleaned herbs into several herb storage compartments on the board.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed merely to enable those skilled in the art to better understand and implement the subject matter described herein. Furthermore, features described in some examples may be combined in other examples.

[0020] likeFigures 1 to 7 As shown, a smart drying device for traditional Chinese medicine includes: Conveyor belt 1; A hot air conveying mechanism 2 is provided on the conveyor belt 1. The hot air conveying mechanism 2 is used to convey hot air with a set temperature and flow rate to a set area on the conveyor belt 1. Several herb storage mechanisms 3, each herb storage mechanism 3 includes a plate 301 and several herb storage sections and speed-up reflux sections disposed on the plate 301. The herb storage sections are used to store herbs to be dried, and the speed-up reflux sections are used to discharge the hot air flowing through the herb storage sections. The conveyor belt 1 is used to drive the plate 301 to a set area on the conveyor belt 1 and place it for a set time. The directional flow guide mechanism 4 is connected to the hot air conveying mechanism 2. The directional flow guide mechanism 4 includes a lifting component, a sealing return component connected to the lifting component, a telescopic flow guide component and a flow splitter component connected to the sealing return component, several airflow guide components connected to the output end of the airflow component, and a partition component connected to the airflow guide component. The lifting component is used to adjust the distance between the sealing return component and the upper end surface of the plate 301. When the sealing return component contacts the upper end surface of the plate 301, the airflow guide component is used to adjust the hot air to flow sequentially through the herb stem diameter and herb leaves before flowing into the sealing return component. The partition component is used to block the hot air from flowing through the herb leaves.

[0021] It should be noted that when using the aforementioned intelligent drying equipment for Chinese herbal medicines to dry herbs whose stems and leaves are medicinal components, the following steps are included: Step 1: Using manual labor or robotic arms, place the cleaned herbs into several herb storage compartments on plate 301. Step 2: The plate 301 filled with herbs is moved to the set area corresponding to the output end of the hot air conveying mechanism 2 by the conveyor belt 1. Step 3: The lifting assembly drives the sealing return assembly to move downward until the lower end of the sealing return assembly contacts and seals the upper end of the plate 301. The hot air conveying mechanism 2 is activated to convey hot air at the set temperature and flow rate to the telescopic guide assembly. The hot air is diverted by the diversion assembly and then conveyed to the corresponding airflow guide assembly. Part of the hot air is guided by the airflow guide assembly and flows through the herb stem diameter and herb leaves in sequence before being discharged into the sealing return assembly. The other part of the hot air flows through the speed-up return section and is discharged into the sealing return assembly. In this process, the stem diameter and leaves can be dried simultaneously by the hot air. The wind force generated by the airflow diverted to the leaves acts on the leaves, so that the leaves can be combed to both sides of the stem diameter. Step 4: After the first set time, the hot air flow through the herb leaves is blocked by the partition component, and all the hot air is driven to flow through the speed-increasing reflux section and then discharged into the sealed reflux component. The first set time is set according to the type of herb to be dried. When the leaves are dried to the required degree after the first set time, in order to prevent them from being dried further and affecting the pharmacological components of the leaves, the airflow diverted to the leaves is blocked by the partition component, so that the leaves are kept in the best drying state. All the hot air can only flow through the speed-increasing reflux section and then be discharged back into the sealed reflux component, which can further improve the drying efficiency of the rod diameter, and the energy consumption remains unchanged, which can effectively increase the production capacity. Step 5: After the second set time, turn off the hot air conveying mechanism 2 and control the partition component and lifting component to return to their original positions in sequence; the second set time is set according to the type of herbs to be dried. Step 6: Drive the next set of plates 301 to the set area on the conveyor belt 1, and repeat steps 3 to 5.

[0022] In an optional embodiment of the invention, such as Figure 2 and Figure 3 As shown, the conveyor belt 1 is provided with several evenly distributed L-shaped positioning members 101, and a limiting area is formed between four adjacent L-shaped positioning members 101 to cooperate with the plate 301.

[0023] It should be noted that, as mentioned above, several L-shaped positioning members 101 are fixedly connected to the conveyor belt body on the conveyor belt 1. The square area formed between every four cooperating L-shaped positioning members 101 is the same area as the plate 301. After the plate 301 is located in the square area, it can move with the L-shaped positioning members 101. When the plate 301 moves to the area covered by the hot air conveying mechanism 2, the conveyor belt 1 stops transporting, so that the plate 301 can be stably located in the area covered by the hot air conveying mechanism 2 for subsequent drying treatment.

[0024] In an optional embodiment of the invention, such as Figure 1 and Figure 2 As shown, the hot air conveying mechanism 2 includes a fixed cover 201 and a heater 202 fixedly installed on the conveyor belt 1, a blower 203 connected to the heater 202, a first conveying pipe 204 connected to the output end of the blower 203, a second conveying pipe 205 fixedly connected to the fixed cover 201, and a first connector 206 connected to the output end of the second conveying pipe 205. The input end of the second conveying pipe 205 is detachably connected to the output end of the first conveying pipe 204.

[0025] It should be noted that, as mentioned above, the blower 203 can guide the air heated inside the heater 202 into the first conveying pipe 204. The hot air flows through the first conveying pipe 204 and the second conveying pipe 205 in sequence before entering the telescopic guide assembly.

[0026] In an optional embodiment of the invention, such as Figure 4 and Figure 5 As shown, the herb storage section includes a storage groove 302 on the plate 301 and a V-shaped limiting groove 303 at the bottom of the storage groove 302. The V-shaped limiting groove 303 is configured to cooperate with the diameter of the herb stem. The speed-up reflux section includes two U-shaped reflux exhaust channels 304 located inside the plate 301. The input ends of the two U-shaped reflux exhaust channels 304 are symmetrically located on both sides of the V-shaped limiting slot 303 and are connected to the internal space of the storage slot 302. The output ends of the two U-shaped reflux exhaust channels 304 are symmetrically located on both sides of the upper opening of the storage slot 302.

[0027] It should be noted that, as mentioned above, after the herbs are cleaned, they are placed in the storage tank 302 by manual or robotic arms, and the stem diameter of the herbs is located in the V-shaped limiting slot 303, which can form a preliminary limit. At this time, the blades on the stem diameter are relatively disordered. However, after the hot air passes through the airflow guide component to adjust the path, the hot air is blown vertically towards the stem diameter and then split to the horizontal sides of the stem diameter. At this time, the blades can be gradually combed to the two sides of the stem diameter under the action of the wind, so that the partition component can separate the blade area from the stem diameter area, thereby preventing the blades from being over-dried.

[0028] In an optional embodiment of the invention, such as Figure 6 As shown, the lifting assembly includes two symmetrically arranged multi-section electric telescopic rods 401 and a welded component connected to the output end of the multi-section electric telescopic rods 401. The multi-section electric telescopic rods 401 are fixedly installed on the fixed cover 201, and the welded component is fixedly connected to the sealing return assembly.

[0029] The sealing reflux assembly includes a movable housing 402, an air inlet located at the upper end of the movable housing 402, and an exhaust port 412 located on the side wall of the movable housing 402. The air inlet is configured to cooperate with the output end of the telescopic flow guide assembly. A flexible hose is connected to the side wall of the movable housing 402, and the flexible hose communicates with the exhaust port 412.

[0030] The telescopic air guide assembly includes a bellows 403 and a connector 404 connected to the input end of the bellows 403. The connector 404 is detachably connected to the connector 206. The output end of the bellows 403 is fixedly connected to the upper outer side of the movable cover 402 and communicates with the air inlet.

[0031] The diversion assembly includes a main diversion pipe 405 and several branch diversion pipes 406 connected to the main diversion pipe 405. Several airflow guiding components are respectively connected to the output end of the corresponding branch diversion pipes 406. The main diversion pipe 405 is fixedly connected to the upper inner side of the movable cover 402 and communicates with the air inlet.

[0032] The airflow guiding assembly includes a sealing cover 407, an air distribution trough 4070 located at the lower end of the sealing cover 407, and two limiting plates 408 fixedly connected to the lower end of the sealing cover 407. The two limiting plates 408 are symmetrically arranged on both sides of the air distribution trough 4070. The length of the sealing cover 407 is greater than the length of the storage trough 302. The length of the limiting plate 408 is the same as the length of the storage trough 302. The thickness of the limiting plate 408 is less than the distance between the input end of the U-shaped return exhaust trough 304 and the side wall of the storage trough 302. A gap is provided between the bottom of the limiting plate 408 and the bottom of the movable cover 402.

[0033] It should be noted that, as mentioned above, when the multi-section electric telescopic rod 401 drives the movable cover 402 to move downward until the movable cover 402 is in close contact with the upper surface of the plate 301, a sealed hot air return chamber is formed between the movable cover 402 and the plate 301. At the same time, the limiting plate 408 is inserted into the storage slot 302. At this time, there is still a gap between the bottom of the limiting plate 408 and the bottom of the storage slot 302, as well as a gap between the two sides of the limiting plate 408 and the inner wall of the storage slot 302. These two gaps are connected in sequence to the gap between the two limiting plates 408 and the air distribution slot 4070. The hot air delivered by the second delivery pipe 205 flows in sequence through the corrugated pipe 403, the first main branch pipe 405 and the first branch pipe 406 before entering the sealing cover 40. In the air distribution trough 4070 on the 7, hot air enters the gap between the two limiting plates 408 after passing through the air distribution trough 4070. The stem diameter and some leaves of the herb are located at the connection between this gap and the gap between the limiting plate 408 and the bottom of the storage tank 302. The hot air blows vertically towards the stem diameter and then begins to split and flows into the gap between the bottom of the limiting plate 408 and the bottom of the storage tank 302. Finally, it is discharged from the gap between the limiting plate 408 and the inner wall of the storage tank 302 into the hot air return chamber. During this process, the wind force acts on the blades, which can gradually comb the blades into the gap between the bottom of the limiting plate 408 and the bottom of the storage tank 302. The other part of the hot air is discharged into the hot air return chamber through the U-shaped return exhaust trough 304.

[0034] In an optional embodiment of the invention, such as Figure 6 and Figure 7As shown, the partition assembly includes a bladder 409 connected to the bottom of the limiting plate 408. The limiting plate 408 has a through hole 4080 communicating with the internal space of the bladder 409. The sealing cover 407 has a through hole 4071 communicating with the through hole 4080. A diversion main pipe 410 is connected to the movable cover 402, and several output ends of the diversion main pipe 410 are connected to diversion branch pipes 411. The output end of the diversion branch pipes 411 is connected to the input end of the through hole 4071. A flexible hose is connected to the input end of the diversion main pipe 410.

[0035] It should be noted that, as mentioned above, after the blade drying time reaches the standard, an external air pressure regulator is used to connect the second hose to the second main diversion pipe 410, thereby adjusting the air pressure inside the bladder 409. This causes the bladder 409 to gradually expand and press against the connection between the rod diameter and the blade. Because the bladder 409 has considerable deformation capacity, it can fully fill the area between the bottom of the limiting plate 408 and the bottom of the storage groove 302, thus forming a stable sealing effect. This prevents hot air from being diverted to the bottom of the limiting plate 408 and the storage groove 302. In the area between the bottom of the groove 302, the blade is sealed, and the hot air can only be discharged through the U-shaped return exhaust groove 304. When the hot air is discharged from the U-shaped return exhaust groove 304, it can flow from the bottom area of ​​the blade, thus slowly drying the bottom of the blade. This can effectively prevent the hot air blown from the top in the previous step from not drying the bottom of the blade sufficiently. After the hot air can only be discharged from the U-shaped return exhaust groove 304, the flow rate of the hot air increases, thus effectively improving the drying efficiency of the hot air on the rod diameter.

[0036] The above description of this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.

10. A method for drying traditional Chinese medicine, characterized in that, The intelligent drying equipment for traditional Chinese medicine as described in any one of claims 1-9 includes the following steps: Step 100: Using manual labor or a robotic arm, place the cleaned herbs into several herb storage compartments on the plate (301); Step 200: The plate (301) filled with herbs is moved to the set area corresponding to the output end of the hot air conveying mechanism (2) by the conveyor belt (1); Step 300: Drive the sealing return assembly downward by the lifting assembly until the lower end of the sealing return assembly contacts and seals the upper end of the plate (301). Start the hot air conveying mechanism (2) to convey hot air with a set temperature and flow rate to the telescopic guide assembly. After the hot air is divided by the diversion assembly, it is conveyed to the corresponding airflow guide assembly. Part of the hot air is guided by the airflow guide assembly and flows through the herb stem diameter and herb leaves in sequence before being discharged into the sealing return assembly. The other part of the hot air flows through the speed-up return section and is discharged into the sealing return assembly. Step 400: After the first set time, the hot air is blocked from flowing through the herb leaves by the partition component, and all the hot air is driven to flow through the speed-up return section and then discharged into the sealed return component. Step 500: After the second set time, shut down the hot air conveying mechanism (2) and control the partition component and lifting component to return to their original positions in sequence; Step 600: Drive the next set of plates (301) to the set area on the conveyor belt (1) via the conveyor belt (1), and repeat steps 300 to 500.
