Description
Technical Field
[0001] This invention relates to the field of equipment for processing Chinese medicinal herbs, and in particular to an online method and equipment for detecting the ash content of processed Chinese medicinal herbs. Background Technology
[0002] The processing of Chinese medicinal herbs has a significant impact on their quality and efficacy. Scientific processing can reduce toxicity and increase efficacy, while unscientific processing often leads to the loss of effective components and even increases toxic side effects. Therefore, quality testing is required for processed Chinese medicinal herbs. Generally, the ash content of the herbs is measured during quality testing. Ash is a solid component in Chinese medicinal materials, mainly consisting of inorganic substances and oxides.
[0003] Current methods for detecting the ash content of Chinese herbal medicine slices typically involve using a detector to analyze the components of the slices on a conveyor belt. However, this method of directly detecting the slices exposed on the conveyor belt in real time is not conducive to avoiding the impact of conveyor belt fluctuations and external environmental factors on the detection. This reduces the accuracy of the detector and makes it impossible to promptly separate qualified and unqualified slices, which can easily lead to confusion and make effective differentiation difficult. Summary of the Invention
[0004] The present invention proposes an online ash content detection method and equipment for processing Chinese herbal medicine slices. The purpose is to solve the problem that the traditional method of directly detecting Chinese herbal medicine slices exposed on the conveyor belt in real time is not conducive to avoiding the impact of conveyor belt fluctuations and external environmental influences on the detection.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An online ash content detection device for processed traditional Chinese medicine decoction pieces includes:
[0007] A frame on which a conveyor belt is mounted;
[0008] The testing mechanism includes a testing groove, a receiving frame, a drive cylinder, a gravity sensor, a tray, a testing box, and a testing instrument. The testing groove is located on a frame, with the top of a conveyor belt passing through it. The receiving frame is slidably connected within the testing groove, with a gap between the receiving frame and the conveyor belt. The same drive frame is fixedly connected to both sides of the receiving frame. A drive cylinder is installed at the bottom of the frame, with one end of the drive frame away from the receiving frame fixedly connected to the output end of the drive cylinder. A tray is slidably connected to the receiving frame, and a gravity sensor is installed between the tray and the receiving frame. Both ends of the tray abut against the upper surfaces of the conveyor belt at both ends within the testing groove. The testing box is fixedly connected to the frame, with an opening at the bottom that is vertically sealed and slidingly fitted with the tray. A testing instrument is installed at the top of the testing box, with its output end facing the tray. The upper surface of the tray and the inner periphery of the testing box form a sealed testing cavity.
[0009] Preferably, guide rollers are rotatably connected to both ends of the top of the detection groove, and pressure rollers are rotatably connected to both ends of the bottom of the detection groove, wherein the top of the conveyor belt passes over the guide rollers, two pressure rollers and the bottom of another guide roller in sequence.
[0010] Preferably, the bottom of the tray is fixedly connected with multiple limiting posts, and the receiving frame is provided with multiple limiting grooves, with the multiple limiting grooves and the multiple limiting posts corresponding to each other and slidingly engaging.
[0011] Preferably, a cleaning assembly is connected to the frame. The cleaning assembly includes a sliding frame, an electric telescopic rod, and a cleaning brush. The sliding frame is slidably connected to the frame. The electric telescopic rod is installed on the frame. The output end of the electric telescopic rod is fixedly connected to the sliding frame. A cleaning brush is fixedly connected to the end of the sliding frame away from the electric telescopic rod. The sliding frame is U-shaped. The receiving frame and the tray are clearance-fitted with the inner circumference of the sliding frame. The bottom of the cleaning brush is slidably fitted with the upper surface of the tray. A discharge port is opened at the bottom of the tray. A valve is installed in the discharge port. The bottom of the discharge port faces the conveyor belt. A collection trough is installed on the frame. The collection trough is located at the bottom of the tray on the side away from the cleaning brush.
[0012] Preferably, the tray has an inclined groove, wherein the discharge port is located at the bottom of the inclined groove near the collection groove, and multiple sealing rings are fixedly connected to the inner circumference of the detection box.
[0013] Preferably, the testing box is connected to a dehumidification assembly, which includes an air inlet pipe, an air outlet pipe, a dehumidifying fan, and a hygrometer. The air inlet pipe and the air outlet pipe are both connected to the top of the testing box. The testing box is equipped with a dehumidifying fan, the input end of which is connected to the output end of an external dry heat source, and the output end of which is connected to the air inlet pipe. A solenoid valve is installed on the air outlet pipe, and the hygrometer is installed inside the testing box.
[0014] An online method for detecting ash content in processed traditional Chinese medicine decoction pieces:
[0015] S1: The conveyor belt transports the Chinese herbal medicine pieces to be tested to the testing tank. Under the action of inertia, the Chinese herbal medicine pieces enter the tray through the inclined chute. The gravity sensor detects the weight of the Chinese herbal medicine pieces, and the driving cylinder drives the receiving frame and the tray to move upward until the tray is sealed and slides into the testing box.
[0016] S2: The dehumidifying fan operates, introducing dry, hot air from the outside into the detection chamber until the humidity meter detects that the humidity inside the detection chamber has stabilized at the predetermined humidity.
[0017] S3: The detector operates to perform component analysis on the Chinese herbal medicine slices on the tray and obtain the ash content information of the Chinese herbal medicine slices;
[0018] S4: After the test is completed, the electric telescopic rod will work to push the Chinese herbal medicine pieces on the reset tray. If the Chinese herbal medicine pieces are qualified, the valve on the discharge port will be opened, so that the Chinese herbal medicine pieces will be pushed from the discharge port onto the conveyor belt to continue the subsequent operation; if the Chinese herbal medicine pieces are unqualified, they will be pushed into the collection tank.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. In this invention, the traditional Chinese medicine (TCM) decoction pieces are carried in a tray and sealed into the detection chamber, which facilitates the detection instrument to perform detection and analysis of the TCM decoction pieces in the sealed detection chamber. Compared with the existing technology of directly detecting TCM decoction pieces exposed on the conveyor belt in real time, this method effectively avoids the impact of conveyor belt fluctuations and external environmental influences on the detection, thereby improving the detection accuracy of the TCM decoction pieces.
[0021] 2. In this invention, the electric telescopic rod pushes the Chinese herbal medicine slices on the reset tray. By opening and closing the valve, qualified and unqualified Chinese herbal medicine slices can be processed accordingly. At the same time, the output end of the electric telescopic rod can be controlled to reciprocate, driving the cleaning brush to clean the upper surface of the tray, preventing dust and moisture from adhering to the upper surface of the tray and improving the protection effect of the tray.
[0022] 3. In this invention, by setting a sealing ring, when the tray is inserted into the detection chamber, the tray vibrates as it passes the sealing ring, which effectively ensures that the Chinese herbal medicine pieces fall to the bottom of the inclined groove and avoids the Chinese herbal medicine pieces from being stuck on the side of the inclined groove. At the same time, the sealing ring improves the sealing of the detection chamber and ensures the stability of the detection environment.
[0023] 4. The present invention includes a dehumidification component, which can perform preliminary heat treatment on the Chinese herbal medicine pieces in the detection chamber, and at the same time keep the humidity in the detection chamber stable at the predetermined humidity, so as to ensure the accuracy of the detection instrument in detecting and analyzing the Chinese herbal medicine pieces.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0031] Reference Figure 1-3 An online ash content detection device for processed traditional Chinese medicine decoction pieces, comprising:
[0032] A frame 1 is provided, on which a conveyor belt 2 is installed. The conveyor belt 2 uses existing technology to transport Chinese herbal medicine slices.
[0033] The testing mechanism includes a testing trough 3, a receiving frame 6, a drive cylinder 7, a gravity sensor 8, a tray 9, a testing box 12, and a testing instrument 14. The testing trough 3 is located on the frame 1, with the top of the conveyor belt 2 passing through it. The receiving frame 6 is slidably connected inside the testing trough 3, with the gap in the receiving frame 6 located above the conveyor belt 2. Guide rollers 4 are rotatably connected to both ends of the top of the testing trough 3, and pressure rollers 5 are rotatably connected to both ends of the bottom of the testing trough 3. The top of the conveyor belt 2 passes around the bottom of the guide rollers 4, two pressure rollers 5, and another guide roller 4 in sequence. The two guide rollers 4 and two pressure rollers 5 make the conveyor belt 2 close to the testing trough 3 and pass around it, facilitating the receiving and return of the Chinese herbal medicine pieces on the conveyor belt 2.
[0034] The same drive frame 71 is fixedly connected to both sides of the receiving frame 6. A drive cylinder 7 is installed at the bottom of the frame 1. The end of the drive frame 71 away from the receiving frame 6 is fixedly connected to the output end of the drive cylinder 7. A tray 9 is slidably connected to the receiving frame 6. A gravity sensor 8 is installed between the tray 9 and the receiving frame 6. The two ends of the tray 9 are respectively abutted against the upper surfaces of the two ends of the conveyor belt 2 located in the detection groove 3. Under the conveying action of the conveyor belt 2, the Chinese medicine decoction pieces pass through the tray 9 under the action of inertia before being inspected.
[0035] The testing box 12 is fixedly connected to the frame 1. The bottom of the testing box 12 has an opening 13, which is sealed and slides in a vertical direction with the tray 9. The top of the testing box 12 is equipped with a detector 14, and the output end of the detector 14 faces the tray 9. The upper surface of the tray 9 and the inner periphery of the testing box 12 form a sealed testing cavity 15. The drive cylinder 7 works and its output end extends, pushing the receiving frame 6 and the tray 9 upward until the tray 9 carries the Chinese herbal medicine pieces and slides into the testing box 12 in a sealed manner. This allows the detector 14 to perform detection and analysis of the Chinese herbal medicine pieces in the sealed testing cavity 15. Compared with the existing technology of directly detecting Chinese herbal medicine pieces exposed on the conveyor belt 2 in real time, this method effectively avoids the influence of conveyor belt 2 fluctuations and external environment on the detection, and improves the detection accuracy of the detector 14.
[0036] The bottom of the tray 9 is fixedly connected with multiple limiting posts 10, and the receiving frame 6 is provided with multiple limiting grooves 11. The multiple limiting grooves 11 and the multiple limiting posts 10 are slidably engaged in a one-to-one correspondence to prevent the tray 9 from twisting on the receiving frame 6, ensuring the stability of the tray 9 during movement, and facilitating the formation of the sealed detection cavity 15.
[0037] A cleaning assembly is connected to the frame 1. The cleaning assembly includes a sliding frame 16, an electric telescopic rod 17, and a cleaning brush 18. The sliding frame 16 is slidably connected to the frame 1. The electric telescopic rod 17 is installed on the frame 1. The output end of the electric telescopic rod 17 is fixedly connected to the sliding frame 16. The cleaning brush 18 is fixedly connected to the end of the sliding frame 16 away from the electric telescopic rod 17. The sliding frame 16 is U-shaped. The receiving frame 6 and the tray 9 are clearance-fitted with the inner circumference of the sliding frame 16. The bottom of the cleaning brush 18 is slidably fitted with the upper surface of the tray 9. The bottom of the tray 9 has a discharge port 19. A valve 20 is installed inside the discharge port 19. The bottom of the discharge port 19 is directly opposite the conveyor belt 2. A collection trough 21 is installed on the frame 1. The collection trough 21 is located at the bottom of the tray 9 on the side away from the cleaning brush 18. When the electric telescopic rod 17 is working, it pushes the Chinese herbal medicine pieces on the reset tray 9. If the Chinese herbal medicine pieces are qualified, the valve 20 on the discharge port 19 is opened, so that the Chinese herbal medicine pieces are pushed from the discharge port 19 onto the conveyor belt 2 to continue the subsequent operation. If the Chinese herbal medicine pieces are unqualified, they are pushed into the collection trough 21 for convenient subsequent unified reprocessing.
[0038] Meanwhile, the output end of the electric telescopic rod 17 can be controlled to reciprocate, thereby driving the cleaning brush 18 to clean the upper surface of the tray 9, preventing dust and moisture from adhering to the upper surface of the tray 9. When the tray 9 is not working, it is located inside the detection box 12, further improving the protection effect of the tray 9.
[0039] The tray 9 has an inclined groove 26, with the discharge port 19 located at the bottom of the inclined groove 26 near the collection tank 21. When the Chinese herbal medicine pieces enter the tray 9, they fall into the bottom of the inclined groove 26 under the action of gravity, preventing the Chinese herbal medicine pieces from scattering and facilitating testing. Multiple sealing rings 27 are fixedly connected to the inner circumference of the testing chamber 12. When the tray 9 is extended into the testing chamber 12, it shakes as it passes the sealing rings 27, effectively ensuring that the Chinese herbal medicine pieces fall into the bottom of the inclined groove 26 and preventing them from being stuck on the side of the inclined groove 26. At the same time, the sealing rings 27 improve the sealing of the testing chamber 15 and ensure the stability of the testing environment.
[0040] A dehumidification assembly is connected to the testing chamber 12. The dehumidification assembly includes an air inlet pipe 22, an air outlet pipe 23, a dehumidifying fan 24, and a hygrometer 25. Both the air inlet pipe 22 and the air outlet pipe 23 are connected to the top of the testing chamber 12. The dehumidifying fan 24 is installed on the testing chamber 12. The input end of the dehumidifying fan 24 is connected to the output end of an external dry hot air source, and the output end of the dehumidifying fan 24 is connected to the air inlet pipe 22. A solenoid valve is installed on the air outlet pipe 23. The hygrometer 25 is installed inside the testing chamber 12. When the dehumidifying fan 24 is working, it introduces external dry hot air into the testing chamber 15 through the air inlet pipe 22 to perform preliminary heat treatment on the Chinese herbal medicine pieces. The humid and hot air in the testing chamber 15 is discharged through the air outlet pipe 23 until the hygrometer 25 detects that the humidity in the testing chamber 15 is stable at a predetermined humidity level. Then, the solenoid valve on the air outlet pipe 23 is closed to ensure the stability of the humidity in the testing chamber 15 and to ensure the accuracy of the testing and analysis of the Chinese herbal medicine pieces by the testing instrument 14.
[0041] An online method for detecting ash content in processed traditional Chinese medicine decoction pieces:
[0042] S1: The conveyor belt 2 transports the Chinese herbal medicine pieces to be tested to the testing tank 3. Under the action of inertia, the Chinese herbal medicine pieces enter the tray 9 through the inclined chute 26. The gravity sensor 8 detects the weight of the Chinese herbal medicine pieces. The drive cylinder 7 drives the receiving frame 6 and the tray 9 to move upward until the tray 9 is sealed and slides into the testing box 12.
[0043] S2: Dehumidifying fan 24 operates, introducing dry hot air from the outside into detection chamber 15 until hygrometer 25 detects that the humidity in detection chamber 15 is stable at the predetermined humidity.
[0044] S3: The detector 14 operates to perform component analysis on the Chinese herbal medicine slices on the tray 9 and obtain the ash content information of the Chinese herbal medicine slices;
[0045] S4: After the test is completed, the electric telescopic rod 17 works to push the Chinese herbal medicine pieces on the reset tray 9. If the Chinese herbal medicine pieces are qualified, the valve 20 on the discharge port 19 is opened, so that the Chinese herbal medicine pieces are pushed from the discharge port 19 onto the conveyor belt 2 to continue the subsequent operation; if the Chinese herbal medicine pieces are unqualified, the Chinese herbal medicine pieces are pushed into the collection tank 21.
