Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine powder detection, and particularly to an apparatus and method for rapidly detecting traditional Chinese medicine powder by using near-infrared. Background Art

[0002] The detection of traditional Chinese medicine powder is crucial in the field of traditional Chinese medicine. Traditional Chinese medicine powder is usually ground from various Chinese medicinal materials, and its quality is directly related to the safety and effectiveness of traditional Chinese medicine preparations. Multiple methods are comprehensively used in the detection process. First, appearance inspection can preliminarily judge the color, texture, uniformity, etc. of the powder, and screen out obvious impurities and abnormalities. Microscopic inspection can observe the microscopic structure of the powder, and identify the authenticity and variety of medicinal materials based on cell characteristics, crystal morphology, etc. Chemical detection qualitatively analyzes chemical components through specific color reactions, thin-layer chromatography, etc., and accurately determines the content of active ingredients by using techniques such as high-performance liquid chromatography. In addition, near-infrared spectroscopy technology can evaluate the quality of Chinese medicinal materials. The quality evaluation of Chinese medicinal materials mainly includes indicators such as humidity, moisture content, impurity content, etc. These indicators are closely related to the quality of Chinese medicinal materials. Through near-infrared spectroscopy technology, these indicators can be rapidly and accurately measured, thereby evaluating the quality of Chinese medicinal materials.

[0003] After traditional Chinese medicine powder is stored for a long time, affected by seasons and sunny / rainy weather, the humidity of the air changes, and the traditional Chinese medicine powder comes into contact with moisture, making it prone to agglomeration, which will affect the efficacy. The agglomerated traditional Chinese medicine may lead to uneven distribution of active ingredients. During decoction or preparation, it is difficult to ensure the uniform release of active ingredients in each part of the medicine, thus reducing the therapeutic effect. For example, for some prescriptions that require precise dosages to take effect, the agglomeration of traditional Chinese medicine may cause the dosages of some herbs to be relatively insufficient or excessive, affecting the stability of the overall efficacy. Secondly, it increases the risk of deterioration. The interior of the agglomerated traditional Chinese medicine powder is prone to form a humid microenvironment, which is conducive to the growth of microorganisms. The water content is also an important indicator for judging whether it has expired and deteriorated. Therefore, the water content of traditional Chinese medicine powder needs to be detected regularly, and corresponding drying treatments should be carried out according to the detection results. Although in traditional detection methods, online detection can be carried out through near-infrared spectroscopy technology combined with a material conveyor belt to obtain the highest, lowest, and average water content data of the traditional Chinese medicine powder in the corresponding batch, and the drying power and duration can be set for the traditional Chinese medicine powder according to the average water content data, the agglomerated traditional Chinese medicine powder usually has a higher water content. If the drying power and duration are set according to the average water content data, it will not only result in incomplete drying but also low energy utilization efficiency. Therefore, the agglomerated traditional Chinese medicine powder needs to be detected separately, and then pre-dried according to the detection data to first reduce the water content of this part of the traditional Chinese medicine powder, and then mix it with other traditional Chinese medicine powders for unified drying treatment. In addition, the near-infrared spectrometer can only detect the water content of the outer materials of the traditional Chinese medicine agglomerates. Due to the wrapping of the outer materials, the interior of the traditional Chinese medicine agglomerates cannot be detected. If the traditional Chinese medicine agglomerates are not crushed first, the detected data will have a large error from the actual data, resulting in a deviation in the judgment of whether the traditional Chinese medicine powder has expired and deteriorated.

[0012] Preferably, a central controller is fixedly connected to the outer surface of the first fixing frame. The central controller, the near-infrared spectrometer, and the heating wire power supply are connected through electrical signals.

[0013] Step 1: First, through the central controller, control the motor to start, the external power supply to heat the heating wire, and the infrared spectrometer to start working. The motor drives the rotating box, the cutting knife, and the blower fan blade to rotate. Then, slowly pour the mixed traditional Chinese medicine powder into the inner cavity of the screening frame. The unagglomerated powder in the traditional Chinese medicine powder will fall into the inner cavity of the collection box through the holes of the screening frame. When the agglomerated traditional Chinese medicine powder passes through the feed pipe, it is first crushed by the rapidly rotating cutting knife, and then falls into the inner cavity of the rotating box. Step 2: After the traditional Chinese medicine powder enters the rotating box, the rotating box drives the traditional Chinese medicine powder to rotate and enters the inner cavity of the transfer box through the unblocked connection port.

When the detected water content decreases, it controls to decrease the power of the heating wire. The traditional Chinese medicine powder that has been detected and pre-dried passes through the arc-shaped screen and then enters the collection cloth bag through the connecting frame for collection. After a certain amount is collected, it is mixed with the traditional Chinese medicine powder in the collection box for the subsequent formal drying process.

[0015] By setting the driving mechanism, the rotating box, the cutting knife, and the blower fan blades can be rotated simultaneously. The agglomerated traditional Chinese medicine powder is first crushed by the cutting knife, and the second-stage crushing is carried out by the crushing mechanism arranged in the rotating box, so that the traditional Chinese medicine mass is crushed into powder, and then the water content is detected, avoiding the problem of inaccurate detection data caused by the agglomeration of traditional Chinese medicine powder. At the same time, the crushing mechanism can prevent the air in the detection box and the transfer box from carrying the material back to the rotating box, preventing the air circulation between the detection box and the rotating box. The multiple crushing cylinders in the crushing mechanism intermittently contact the arc-shaped rolling plate to complete the process of supplementing materials from the rotating box to the transfer box and then outputting materials from the transfer box to the detection box. While the materials are being directionally transported, the second crushing operation is carried out on the materials, enabling the device to have the function of continuous feeding. In addition, by setting the connection of the central controller, the near-infrared spectrometer, and the heating wire power supply, the heating power can be intelligently controlled, which can not only ensure the drying efficiency but also avoid over-drying and save energy.

One end inner wall of the rotating box 53 away from the motor 51 is fixedly connected with a sliding bearing 58. The inner ring of the sliding bearing 58 is fixedly connected with a feed pipe 59. One end of the feed pipe 59 away from the sliding bearing 58 is fixedly connected with a screening frame 510. The outer surface of the screening frame 510 is fixedly connected with the top end of the first support rod 10. One end of the rotating rod 52 extending outside the rotating box 53 is fixedly connected with a cutting knife 511. The cutting knife 511 is located in the inner cavity of the feed pipe 59. By setting the cutting knife 511, large pieces of traditional Chinese medicine mass in the inner cavity of the feed pipe 59 can be cut and broken when the rotating rod 52 rotates. By setting the sliding bearing 58, the friction between the rotating box 53 and the feed pipe 59 can be reduced, so that when the rotating box 53 rotates, the feed pipe 59 will not rotate. By setting the screening frame 510, the traditional Chinese medicine powder entering the inner cavity of the rotating box 53 can be screened, so that the unclumped traditional Chinese medicine powder can pass through the holes of the screening frame 510 and fall into the collection box 9. By setting the feed pipe 59, the clumped traditional Chinese medicine powder can enter the inner cavity of the rotating box 53 from the screening frame 510.

[0021] The outer surface of the rotating box 53 is provided with a crushing mechanism 57.

By arranging the blocking plate 5710, the inner cavity of the connection port 571 can be blocked by the blocking plate 5710 when the sliding plate 575 moves downward. By arranging the limiting frame 574, the sliding plate 575 can be limited, so that the sliding plate 575 can move vertically up and down in the inner cavity of the limiting frame 574. By arranging the spring 576, the sliding plate 575 can be extruded, so that the sliding plate 575 is always subjected to an upward force. By arranging the limiting block 577, the crushing cylinder 578 can be limited, so that the crushing cylinder 578 can rotate stably.

The arc-shaped crushing plate 66 is in extrusion fit with the crushing cylinder 578. A transparent plate penetrates through the outer surface of the detection box 61. By providing the arc-shaped crushing plate 66, it can cooperate with the crushing cylinder 578, so that the agglomerated traditional Chinese medicine mass is crushed into powder. An installation frame 64 penetrates through one side of the detection box 61 away from the transparent plate. A near-infrared spectrometer 65 penetrates through the outer surface of the installation frame 64. A central controller 11 is fixedly connected to the outer surface of the first fixing frame 2. By providing the central controller 11 and the near-infrared spectrometer 65, the traditional Chinese medicine in the inner cavity of the detection box 61 can be detected, so as to detect the particle size and mixing degree of the traditional Chinese medicine particles. An arc-shaped sieve mesh 62 is embedded in the bottom surface of the inner cavity of the detection box 61. A connecting frame 67 is fixedly connected to the lower surface of the arc-shaped sieve mesh 62. A collecting cloth bag 68 penetrates through and is connected to the lower surface of the connecting frame 67. The collecting cloth bag 68 is used for collecting the traditional Chinese medicine powder after preliminary drying and at the same time allowing the air in the detection box 61 to flow out.

[0023] An arc-shaped crushing plate 66 is fixedly connected to the top surface of the inner cavity of the detection box 61. The arc-shaped crushing plate 66 is in extrusion fit with the crushing cylinder 578. It should be noted that the arc-shaped crushing plate 66 protrudes from the top surface of the inner cavity of the detection box, and both ends of the arc-shaped crushing plate 66 are transitioned with the inner cavity wall of the detection box 61 through an arc surface to ensure that the crushing cylinder 578 can smoothly roll onto the surface of the arc-shaped crushing plate 66.

[0024] The drying mechanism 7 includes a first roller 71 and a third support rod 74. The first roller 71 is fixedly connected to the outer surface of the rotating rod 52. The first roller 71 is connected to a second roller 73 through a belt 72. The third support rod 74 is fixedly connected to the lower surface of the bottom frame 8. A limit sleeve 75 is fixedly connected to the end of the third support rod 74. A circular ring 76 is rotatably connected to the inner cavity of the limit sleeve 75. A rotating column 77 is fixedly connected to the inner ring of the circular ring 76. The end of the rotating column 77 is fixedly connected to the outer surface of the second roller 73.

A heating wire 79 is fixedly connected to the inner wall of the connecting pipe 78. The heating wire 79 is connected to an external power supply. The power supplies of the central controller 11, the near-infrared spectrometer 65, and the heating wire 79 are connected through electrical signals. The other end of the connecting pipe 78 is fixedly connected to an air inlet box 710. A separation net 711 is fixedly connected to the opening of the air inlet box 710. A blower fan blade 712 is fixedly connected to one end of the rotating column 77 located in the inner cavity of the air inlet box 710. By providing the limit sleeve 75, the circular ring 76 can be limited, so that the circular ring 76 and the rotating column 77 rotate stably. By providing the first roller 71, the second roller 73, and the belt 72, when the rotating rod 52 rotates, the rotating column 77 can be driven to rotate. By providing the blower fan blade 712 and drivingly connecting it to the drive shaft of the motor 51, the motor 51 can not only drive the rotating box 53 to rotate, but also drive the blower fan blade 712 to work, input air into the detection box 61. The air passes through the heating wire 79 and is heated and raised in temperature, and the traditional Chinese medicines in the detection box 61 can be pre-dried respectively, reducing the water content of the agglomerated traditional Chinese medicine powder, and avoiding incomplete drying caused by uneven water content of the traditional Chinese medicine powder in the subsequent drying process. The near-infrared spectrometer 65 monitors the water content of the traditional Chinese medicine powder in the detection box 61 and transmits the real-time data to the central controller 11. When the detected water content increases, the central controller 11 controls to increase the power of the heating wire 79 to ensure the drying effect. When the detected water content decreases, it controls to reduce the power of the heating wire 79 to avoid over-drying and wasting energy.

[0025] A method for quickly detecting traditional Chinese medicine powder using near-infrared includes the following steps: Step 1: First, through the central controller 11, control the motor to start, the external power supply to heat the heating wire 79, and the infrared spectrometer 65 to start working. The motor drives the rotating box 53, the cutting knife 511, and the blower fan blade 712 to rotate. Then, slowly pour the mixed traditional Chinese medicine powder into the inner cavity of the screening frame 510. The unagglomerated powder in the traditional Chinese medicine powder will fall into the inner cavity of the collection box 9 through the holes of the screening frame 510. When the agglomerated traditional Chinese medicine powder passes through the feed pipe 59, it is first broken by the rapidly rotating cutting knife 511, and then falls into the inner cavity of the rotating box 53; Step 2: After the traditional Chinese medicine powder enters the rotating box 53, the rotating box 53 drives the traditional Chinese medicine powder to rotate and enters the inner cavity of the transfer box 573 through the unblocked connection port 571; Step 3: After the grinding cylinder 578 in the transfer box 573 contacts and presses against the arc-shaped rolling plate 66, the traditional Chinese medicine mass is ground into powder and falls into the inner cavity of the detection box 61. The blower fan blade 712 blows air into the detection box 61, and the air flow is heated when passing through the heating wire 79 to pre-dry the traditional Chinese medicine powder after secondary crushing; Step 4: During the pre-drying process, the near-infrared spectrometer 65 real-time detects the water content of the traditional Chinese medicine powder in the inner cavity of the detection box 61 and transmits the real-time data to the central controller 11. When the detected water content increases, the central controller 11 controls the external power supply to increase the power of the heating wire 79. When the detected water content decreases, it controls to decrease the power of the heating wire 79. The traditional Chinese medicine powder that has been detected and pre-dried passes through the arc-shaped screen 62 and then enters the collection cloth bag 68 through the connection frame 67 for collection. After a certain amount is collected, it is mixed with the traditional Chinese medicine powder in the collection box 9 for subsequent formal drying process.

[0026] Working principle: When in use, the operator starts the motor first, and then pours the Chinese medicine powder to be tested into the inner cavity of the screening frame 510. The unagglomerated powder in the Chinese medicine powder will fall into the inner cavity of the collecting box 9 through the holes of the screening frame 510. The water content of the unagglomerated Chinese medicine powder is reduced, and there is no need to perform water content detection and pre-drying. When the agglomerated Chinese medicine powder passes through the feeding pipe 59 again, the cutting knife 511 rotates rapidly under the drive of the rotating rod 52, and performs the first crushing of the agglomerated Chinese medicine powder, which can eliminate larger Chinese medicine clumps. After the crushing, the Chinese medicine powder enters the rotating box 53 under the push of subsequent materials. The centrifugal force of the high-speed rotation of the rotating box 53 causes the Chinese medicine powder to enter the rolling mechanism 57, and the crushing cylinder 578 cooperates with the arc-shaped rolling plate 66 to crush the insufficiently crushed Chinese medicine powder. The medicine mass undergoes a second crushing and crushing process. During this process, when the crushing cylinder 578 is not in contact with the arc-shaped crushing plate 66, the crushing cylinder 578, under the action of the spring 576 and the centrifugal force, prevents the blocking plate 5710 linked thereto from blocking the connecting port 571, thereby allowing the material in the rotating box 53 to enter the transfer box 573; when the crushing cylinder 578 is in contact with the arc-shaped crushing plate 66, due to the contact and extrusion between the two, the crushing cylinder 578 shrinks into the transfer box 573, thereby causing a gap to appear between the crushing cylinder 578 and the upper end outlet of the transfer box 573, for the output of the Chinese medicine powder. At the same time, the crushing cylinder 578 rotates under the action of the contact and friction with the arc-shaped crushing plate 66, and crushes and crushes the agglomerated Chinese medicine powder output from the upper end opening of the transfer box 573, thereby crushing the agglomerated Chinese medicine powder output from the upper end opening of the transfer box 573. At the same time, driven by the retraction force of the crushing cylinder 578, the blocking plate 5710 blocks the connecting port 571 between the transfer box 573 and the rotating box 53, preventing the air in the detection box 61 and the transfer box 573 from carrying the material back into the rotating box 53, and preventing air circulation between the detection box 61 and the rotating box 53. In this way, multiple crushing cylinders 578 intermittently contact the arc-shaped crushing plate 66 to complete the process of replenishing materials from the rotating box 53 to the transfer box 573, and then outputting materials from the transfer box 573 to the detection box 61. While the materials are transported in a directional manner, a second crushing operation is performed on the materials, so that the device has the function of continuous feeding; by providing the blower blades 712 and connecting them to the driving shaft of the motor 51, the motor 51 can drive the rotating box 5 3 rotates, and can drive the blower blades 712 to work, blowing air into the detection box 61. The air passes through the heating wire 79 and is heated to pre-dry the Chinese medicine powder in the detection box 61, reducing the water content of the agglomerated part of the Chinese medicine powder, and avoiding incomplete drying due to uneven water content of the Chinese medicine powder in the subsequent drying process. During the pre-drying process, the near-infrared spectrometer 65 monitors the water content of the Chinese medicine powder in the detection box 61, and transmits the real-time data to the central controller 11. When the detected water content increases, the central controller 11 controls the external power supply to increase the power of the heating wire 79 to ensure the drying effect. When the detected water content decreases, the power of the heating wire 79 is controlled to decrease to avoid excessive drying and save energy.
