Description

Technical Field

[0001] This invention relates to the field of near-infrared spectroscopy octagonal detection technology, and in particular to a rapid octagonal detection device based on near-infrared spectroscopy. Background Technology

[0002] Star anise is an important economic tree species in my country that is both food and medicine. It is a specialty spice and traditional Chinese medicine. Due to differences in place of origin, ecological environment, harvesting season, processing methods and storage conditions, the quality of star anise varies, especially its effective components. General sensory tests (color, smell, etc.) cannot accurately determine the intrinsic quality of star anise. Therefore, it is of great significance to establish quality evaluation standards for star anise.

[0003] A rapid near-infrared spectroscopy method for detecting the quality of star anise, with announcement number CN106770008A, includes sample set construction, influencing factor analysis, model establishment, and performance prediction. Based on near-infrared spectroscopy, this method, through a series of operations such as sample particle size determination, sample quantity, number of scans, spectral preprocessing, characteristic spectrum extraction, model establishment, and predictive analysis, can rapidly and accurately determine the content of effective components in star anise, thus confirming its quality. This provides technical support for industry supervision, management, and standardization, and has significant practical application value.

[0004] The above technical solution demonstrates how to detect the component content of star anise using near-infrared spectroscopy. However, how to accurately capture infrared spectral images of star anise and avoid affecting the resolution quality of the spectral images due to shaking or stacking of star anise is a difficult problem in this field. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an octagonal rapid detection device based on near-infrared spectroscopy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An octagonal rapid detection device based on near-infrared spectroscopy includes a conveyor belt assembly. An intermittent drive mechanism is installed on one side of the conveyor belt assembly. A near-infrared spectroscopy detection device is installed on the conveyor belt assembly. Support mechanisms are provided on both sides of the conveyor belt assembly. Two pressure plates are provided on the support mechanisms. A linkage mechanism is provided on one side of the pressure plates. A bending partition and a synchronous belt drive assembly are provided on the linkage mechanism. An adaptation mechanism is provided on the pressure plates. A slider is provided on the adaptation mechanism. A push-pull mechanism is provided at the upper end of the pressure plates. A top plate is provided on the push-pull mechanism. Tensioning shafts are rotatably sleeved on one side of the upper end of the pressure plates, the upper end of the slider, and both sides of the lower end of the top plate. A limiting conveyor belt is sleeved on the four tensioning shafts located on the same side. The opposite ends of the two limiting conveyor belts are located at the top of the conveyor belt assembly, and the two limiting conveyor belts are located on one side of the two bent partitions respectively. One of the top plate components is equipped with a lifting mechanism, and the other top plate component is equipped with an elastic mechanism. Both the lifting mechanism and the elastic mechanism are equipped with lifting rods, and the upper ends of the two lifting rods are rotatably connected to a flat scraper component. The flat scraper is located between the two limiting conveyor belts, and the flat scraper is located at the upper end of the conveyor belt assembly.

[0007] Compared with the prior art, the present invention enables the conveyor belt assembly to operate intermittently, thereby causing the octagonal components transported on it to move intermittently, and avoiding the stacking of the octagonal components during movement. This ensures that there is no obstruction between the octagonal components under the near-infrared spectroscopy detection equipment, thereby improving the quality of infrared spectroscopy imaging and thus improving the detection quality based on infrared spectroscopy.

[0008] Preferably, the linkage mechanism includes a lifting rod that passes through one end of the pressure plate. A first shaft assembly is fixed to the upper end of the lifting rod. A first horizontal shaft is sleeved inside the first shaft assembly. A first abutting wheel is fixed to one end of the first horizontal shaft. The bending partition and the first abutting wheel are rotatably connected. One end of the bending partition extends to the outside of the conveyor belt assembly. A support frame is fixed to one side of the bending partition. The support frame is slidably installed on one side of the first shaft assembly. A double bevel gear transmission assembly is installed at the end of the first horizontal shaft away from the first abutting wheel. The double bevel gear transmission assembly is installed on the first shaft assembly. A synchronous belt transmission assembly is connected to the lower end of the double bevel gear transmission assembly. The synchronous belt transmission assembly is connected to a tensioning shaft that is rotatably sleeved on the upper end of the pressure plate on the same side as the synchronous belt transmission assembly. The lifting rod is connected to the support mechanism. A support rod is provided between the first horizontal shaft and the support mechanism on the same side as the synchronous belt transmission assembly.

[0009] Furthermore, by fixing the first fixed frame and the conveyor belt assembly together, the pressure plate can abut against both sides of the upper end of the frame inside the conveyor belt assembly. The conveyor belt inside the conveyor belt assembly is located between the two pressure plates. The lifting rod facilitates the installation of the first shaft assembly, which drives the first abutting wheel so that the lower end of the first abutting wheel abuts against the upper end of the conveyor belt inside the conveyor belt assembly. Through friction transmission, the first abutting wheel rotates in the opposite direction to the conveyor belt inside the conveyor belt assembly. Through the cooperation of the first horizontal shaft and the double bevel gear transmission assembly, the synchronous belt transmission assembly is driven to operate. The synchronous belt transmission assembly can drive the tensioning shaft connected to it to rotate. Through the rotation of the tensioning shaft, the section of the limiting conveyor belt located at the upper end of the conveyor belt assembly can be moved in the same direction as the conveyor belt inside the conveyor belt assembly. During actual production, workers need to note that the double bevel gear transmission assembly consists of two meshing bevel gears and corresponding mounting brackets. It can connect to the first shaft assembly without affecting the rotation of the double bevel gear transmission assembly. The first horizontal shaft passes through one bevel gear in the double bevel gear transmission assembly and allows that bevel gear to rotate, causing the other bevel gear to rotate. At the same time, the other bevel gear can drive the components in the synchronous belt transmission assembly. The synchronous belt transmission assembly consists of pulleys and belts. To ensure the power transmission effect, a toothed structure can be set. The other bevel gear can drive one of the pulleys to rotate, allowing the other pulley to rotate through the belt. The other pulley and one of the tensioning shafts are fixedly mounted and coaxially arranged, driving the tensioning shaft to rotate, thus providing power. Furthermore, during manufacturing, the specifications and proportions between the corresponding components can be controlled, which helps to achieve the same speed rotation of the limit conveyor belt and the conveyor belt in the conveyor belt assembly.

[0010] Preferably, the support mechanism includes two first fixed frames detachably connected to both sides of the conveyor belt assembly, two pressure plates respectively fixed to the upper ends of the two first fixed frames, the two pressure plates respectively disposed on both sides of the conveyor belt assembly, a second fixed frame detachably connected to the side of the first fixed frame near the conveyor belt assembly, a pressing mechanism installed at the end of the second fixed frame away from the first fixed frame, the pressing mechanism being provided with second abutment wheels, the two second abutment wheels being respectively located at the lower ends of the two bent partitions, and the lifting rod and the support rod being connected to the pressing mechanism.

[0011] Furthermore, multiple through holes can be opened on the first fixed frame. Bolts can be installed through the uppermost through hole and any other through hole. The bolt in the uppermost through hole can be screwed into the transport frame inside the conveyor belt assembly to ensure the connection is firm. Another bolt will be inserted into the corresponding through hole according to the actual situation to facilitate the lifting and lowering of the second fixed frame that passes through it. The second fixed frame can be controlled to drive the second abutment wheel through the second shaft assembly and the second horizontal shaft to enable the second abutment wheel to cooperate with the first abutment wheel located above it, and to closely abut against the upper and lower ends of the conveyor belt inside the conveyor belt assembly to ensure the quality and effect of friction transmission. Furthermore, textures can be provided on the first abutment wheel and the conveyor belt assembly to increase friction.

[0012] Preferably, the adaptation mechanism includes a slide groove disposed on one side of the upper end of the pressure plate, the slider is slidably installed in the slide groove, and a resistance spring is fixed together on the slider and the side wall of the slide groove.

[0013] Furthermore, by controlling the extension and retraction of the electric telescopic rod, the piston rod of the electric telescopic rod pushes the top plate component fixed to it to move. When the top plate component drives the two tensioning shafts at its lower end to operate, the limiting conveyor belt applies pressure to the tensioning shafts on the slider component. The pressure can be transmitted to the resistance spring component through the slider component, causing the resistance spring component to contract in order to adapt to the movement of the slider component and its upper tensioning shafts. At the same time, the resistance spring component will give the slider component a reverse push, which helps to ensure the tension of the limiting conveyor belt. By driving the movement of the tensioning shafts at its lower end through the top plate component, the width of the conveyor belt within the conveyor belt assembly that allows the octagon to pass through can be adjusted. Moreover, the vertical setting of the limiting conveyor belt can effectively ensure that the octagon can only move between the two limiting conveyor belts; that is, it can fully limit the number of octagons that can pass through. In addition, with the help of the flat scraper component, it can avoid the situation of stacking, which improves the imaging quality of infrared spectrum when the near-infrared spectroscopy detection equipment is used for imaging.

[0014] Preferably, the push-pull mechanism includes an electric telescopic rod fixed to the upper end of the pressure plate, the piston rod end of the electric telescopic rod is fixedly connected to the lower end of the top plate, and the piston rod of the electric telescopic rod is located between two tensioning shafts at the lower end of the top plate.

[0015] Furthermore, the extension and retraction of the piston rod of the electric telescopic rod can drive the two tensioning shafts at the lower end of the top plate to move. Through the cooperation of the resistance spring, the slider, and the tensioning shafts on the slider, the tension of the limiting conveyor belt can be guaranteed.

[0016] Preferably, the lifting mechanism includes a lifting bolt threaded onto one of the top plate components, a linkage plate component rotatably connected to the lower end of the lifting bolt component, a lifting rod component rotatably connected to the upper end of the linkage plate component, and a lifting rod component sleeved on one of the top plate components.

[0017] Furthermore, the position and height of the lower linkage plate of the lifting bolt can be controlled by rotating the lifting bolt, and the leveling scraper can be raised and lowered by the lifting rod, which makes it easy to control the distance between the leveling scraper and the conveyor belt in the conveyor belt assembly, so as to achieve leveling octagonal; During actual preparation, the staff can control the distance between the flat scraper and the conveyor belt in the conveyor belt assembly to be greater than the height of an octagon after being laid flat and less than the height of two octagons stacked. At the same time, the flat scraper can be made of plastic or rubber materials, and the lower end of the flat scraper on the side near the octagon feeding can be inclined and chamfered to avoid damaging the octagon.

[0018] Preferably, the elastic mechanism includes a through opening on another top plate member, a linkage block is slidably installed in the through opening, another lifting rod is sleeved on the linkage block, and a tension spring is fixed together on the inner wall of the linkage block and the through opening.

[0019] Furthermore, when the two top plate components move in opposite directions, increasing the distance between them, the second fixed frame will drive the lifting rod in the linkage block to push the linkage block to move within the through opening, so that the second fixed frame gradually operates in a direction perpendicular to the two top plate components to adapt to the increase in the distance between them. When the distance between the two top plate components decreases, the tension spring component can pull the linkage block to cause the lifting rod component to tilt the second fixed frame. This will also cause the flat scraper component and the two top plate components to tilt, which is convenient to adapt to the gradual reduction of the distance between the two top plate components and will not affect the movement of the limiting conveyor belt. It can also perform flat laying operations on the octagon that enters between the two limiting conveyor belts.

[0020] Preferably, the extrusion mechanism includes a second fixed frame detachably connected to the first fixed frame, a second shaft assembly rotatably sleeved at the end of the second fixed frame away from the first fixed frame, a second horizontal shaft rotatably sleeved inside the second shaft assembly, a second abutting wheel fixed at one end of the second horizontal shaft extending into the conveyor belt assembly, a fastening bolt screwed onto the second shaft assembly, the fastening bolt abutting against the second horizontal shaft, the lower end of the support rod being mounted on one end of the second horizontal shaft, and the lifting rod being slidably mounted on one side of the second fixed frame.

[0021] Furthermore, during operation, the first and second horizontal axes can be finely adjusted via the support rod to align the first and second contact wheels with the conveyor belt within the conveyor belt assembly. The positional relationship between the second shaft assembly and the second horizontal axis is fixed by fastening bolts, ensuring the stability of the positions of the first and second horizontal axes. In actual manufacturing, both the fastening bolts and the second horizontal axis are slidably mounted on the support rod, allowing adjustment of the distance between the first and second contact wheels.

[0022] Preferably, the intermittent drive mechanism includes a drive motor assembly mounted on one side of the conveyor belt assembly, an intermittent output assembly connected to the end of the output shaft of the drive motor assembly, a speed regulating transmission assembly mounted on the intermittent output assembly, and the speed regulating transmission assembly connected to the conveyor belt assembly.

[0023] Furthermore, the drive motor assembly can drive the intermittent output assembly to operate, enabling the final output component to move intermittently. This movement method is an existing technical solution and does not need to be disclosed again. The speed regulation transmission assembly consists of two pulleys of different sizes and a belt fitted on these two pulleys. The large pulley is connected to the output end of the intermittent output assembly and moves synchronously. The small pulley is connected to the conveyor roller shaft inside the conveyor belt assembly to drive the conveyor belt assembly to move. This can drive the octagonal intermittent movement on it, so that the octagonal intermittent movement passes through the near-infrared spectroscopy detection equipment, so that the near-infrared spectroscopy detection equipment can improve the quality of the octagonal infrared spectroscopy detection image.

[0024] Preferably, the flat scraper is inclined.

[0025] Furthermore, by tilting the device, the distance between the two limiting conveyor belts can be reduced, thereby controlling the number of octagons passing between the two limiting conveyor belts and ensuring that the near-infrared spectroscopy detection equipment can accurately capture images of the octagons.

[0026] The beneficial effects of this invention are: 1. By controlling the extension and retraction of the electric telescopic rod, the piston rod of the electric telescopic rod pushes the top plate component fixed to it to move. When the top plate component drives the two tensioning shafts at its lower end to operate, the limiting conveyor belt will apply pressure to the tensioning shafts on the slider component. The pressure can be transmitted to the resistance spring component through the slider component, causing the resistance spring component to contract in order to adapt to the movement of the slider component and the tensioning shafts on it. At the same time, the resistance spring component will give the slider component a reverse push, which helps to ensure the tension of the limiting conveyor belt. The movement of the tensioning shafts at its lower end driven by the top plate component can adjust the width of the conveyor belt within the conveyor belt assembly that allows the octagon to pass through. Furthermore, the vertical setting of the limiting conveyor belt can effectively ensure that the octagon can only move between the two limiting conveyor belts; that is, it can fully limit the number of octagons that can pass through. In addition, with the help of the flat scraper component, it can avoid the stacking situation, which improves the imaging quality of infrared spectrum when the near-infrared spectroscopy detection equipment is used for imaging. 2. The staff can control the distance between the flat scraper and the conveyor belt in the conveyor belt assembly to be greater than the height of an octagon after being laid flat and less than the height of two octagons stacked. At the same time, the flat scraper can be made of plastic or rubber materials, and the lower end of the flat scraper on the side near the octagon feeding can be inclined and chamfered to avoid damaging the octagon. 3. The drive motor assembly can drive the intermittent output assembly to operate, so that the final output component can move intermittently. This movement method is an existing technical solution and does not need to be disclosed again. The speed regulation transmission assembly consists of two pulleys of different sizes and belts fitted on these two pulleys. The large pulley is connected to the output end of the intermittent output assembly and moves synchronously. The small pulley is connected to the conveyor roller shaft in the conveyor belt assembly to drive the conveyor belt assembly to move. This can drive the octagonal intermittent movement on it, so that the octagonal intermittent movement can pass through the near-infrared spectroscopy detection equipment, so that the near-infrared spectroscopy detection equipment can improve the quality of the octagonal infrared spectroscopy detection image.

Detailed Implementation

[0028] 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.

[0029] Reference Figure 1-8 An octagonal rapid detection device based on near-infrared spectroscopy includes a conveyor belt assembly 1. The conveyor belt assembly 1 adopts existing conveyor belt transportation equipment, which consists of a conveyor belt, a support frame, two drive shafts, multiple contact support shafts, a motor assembly, control equipment, etc. The multiple contact support shafts may also adopt a flat plate structure, so that they abut against the lower end of the conveyor belt to ensure the smooth movement of the conveyor belt. In this example, a conveyor belt device with one end that is telescopic and adjustable is used in the prior art. An intermittent drive mechanism is installed on one side of the conveyor belt assembly 1. A near-infrared spectroscopy detection device 31 is installed on the conveyor belt assembly 1. The near-infrared spectroscopy detection device 31 can take pictures of the octagon passing under its lower end to obtain the near-infrared spectral image of the octagon.

[0030] In this embodiment, a support mechanism is provided on both sides of the conveyor belt assembly 1. The support mechanism is provided with two pressure plates 20. The support mechanism includes two first fixing frames 21 detachably connected to both sides of the conveyor belt assembly 1. The positions of the pressure plates 20 and the first fixing frames 21 can be set according to the structure of the conveyor belt assembly 1. The two pressure plates 20 are respectively fixed to the upper ends of the two first fixing frames 21. The two pressure plates 20 are respectively set on both sides of the conveyor belt assembly 1. A second fixing frame 28 is detachably connected to the side of the first fixing frame 21 near the conveyor belt assembly 1. A pressing mechanism is installed at the end of the second fixing frame 28 away from the first fixing frame 21. The pressing mechanism is provided with a second abutment wheel 27. The two second abutment wheels 27 are respectively located at the lower ends of the two bent partitions 23. The lifting rod 12 and the support rod are both connected to the pressing mechanism. After the positions of the pressure plates 20 and the first fixing frames 21 are fixed, other components can be installed to facilitate connection with the conveyor belt assembly 1 to form an integral device, so as to enable octagonal transportation and flat laying operation during transportation.

[0031] In this embodiment, the extrusion mechanism includes a second fixed frame 28 detachably connected to the first fixed frame 21. A second shaft assembly 24 is rotatably sleeved at the end of the second fixed frame 28 away from the first fixed frame 21. A second horizontal shaft 25 is rotatably sleeved inside the second shaft assembly 24. A second abutment wheel 27 is fixed at one end of the second horizontal shaft 25 extending into the conveyor belt assembly 1. A fastening bolt 26 is screwed onto the second shaft assembly 24. The fastening bolt 26 abuts against the second horizontal shaft 25. Rotating the fastening bolt 26 fixes the positional relationship between the second shaft assembly 24 and the second horizontal shaft 25, effectively ensuring that rotation of the second horizontal shaft 25 also causes rotation of the second shaft assembly 24, without affecting the rotation of the second abutment wheel 27. The lower end of the support rod is installed at one end of the second horizontal shaft 25, which will not interfere with the rotation of the second horizontal shaft 25. The lifting rod 12 is slidably installed on one side of the second fixed frame 28 to ensure that the first shaft assembly 14 can be raised and lowered smoothly. The upper end of the lifting rod 12 can be fixed to one side of the first shaft assembly 14, or it can be set in an inverted L shape to effectively ensure that the first contact wheel 22 is located at the upper end of the second contact wheel 27. The support rod can pull the first horizontal shaft 16 and the second horizontal shaft 25 to move slightly, so that the first contact wheel 22 can contact the edge of the conveyor belt in the conveyor belt assembly 1 and cooperate with the second contact wheel 27 to clamp it, ensuring stable power transmission without affecting the transportation of the octagon.

[0032] In this embodiment, a linkage mechanism is provided on one side of the pressure plate 20. The linkage mechanism is equipped with a bending partition 23 and a synchronous belt drive assembly 17. The linkage mechanism includes a lifting rod 12 that passes through one end of the pressure plate 20. A first shaft assembly 14 is fixed to the upper end of the lifting rod 12. A first horizontal shaft 16 is sleeved inside the first shaft assembly 14. A first contact wheel 22 is fixed to one end of the first horizontal shaft 16. The bending partition 23 and the first contact wheel 22 are rotatably connected. One end of the bending partition 23 extends to the conveyor belt assembly 17. On the outer side, a support frame 15 is fixed to one side of the bent partition 23. The support frame 15 is slidably mounted on one side of the first shaft assembly 14. A double bevel gear transmission assembly 13 is mounted on the end of the first horizontal shaft 16 away from the first contact wheel 22. The double bevel gear transmission assembly 13 is mounted on the first shaft assembly 14. A synchronous belt transmission assembly 17 is connected to the lower end of the double bevel gear transmission assembly 13. The synchronous belt transmission assembly 17 is connected to the tensioning shaft 3 on the same side and rotatably sleeved on the upper end of the pressure plate 20. The lifting rod 12 is connected to the support mechanism, and the first horizontal shaft 16 and the support mechanism on the same side are provided with a support rod. After the first fixed frame 21 and the conveyor belt assembly 1 are fixedly connected, the pressure plate 20 can abut against the two sides of the upper end of the frame inside the conveyor belt assembly 1. The conveyor belt inside the conveyor belt assembly 1 is located between the two pressure plates 20. The lifting rod 12 facilitates the installation of the first shaft assembly 14 to drive the first abutting wheel 22, so that the lower end of the first abutting wheel 22 abuts against the upper end of the conveyor belt inside the conveyor belt assembly 1. The first abutting wheel 22 rotates in the opposite direction with the conveyor belt inside the conveyor belt assembly 1 through friction transmission. The synchronous belt transmission assembly 17 is driven to operate through the cooperation of the first horizontal shaft 16 and the double bevel gear transmission assembly 13. The synchronous belt transmission assembly 17 can drive the tensioning shaft 3 connected to it to rotate. Through the rotation of the tensioning shaft 3, the section of the limiting conveyor belt 4 located at the upper end of the conveyor belt assembly 1 can move in the same direction as the conveyor belt inside the conveyor belt assembly 1.

[0033] In this embodiment, the pressure plate 20 is provided with an adaptation mechanism, and the adaptation mechanism is provided with a slider 18. The adaptation mechanism includes a slide groove 19 provided on one side of the upper end of the pressure plate 20. The slider 18 is slidably installed in the slide groove 19. A resistance spring 29 is fixed on the side wall of the slider 18 and the slide groove 19. The piston rod of the electric telescopic rod 30 pushes the top plate 8 fixed thereto to move. When the top plate 8 drives the two tensioning shafts 3 at its lower end to operate, the limiting conveyor belt 4 will apply pressure to the tensioning shafts 3 on the slider 18. The pressure can be transmitted to the resistance spring 29 through the slider 18, causing the resistance spring 29 to contract in order to adapt to the movement of the slider 18 and the tensioning shafts 3 on it, and also to ensure the tension of the limiting conveyor belt 4, so as to ensure that the limiting conveyor belt 4 can rotate stably.

[0034] In this embodiment, a push-pull mechanism is provided at the upper end of the pressure plate 20, and a top plate 8 is provided on the push-pull mechanism. The push-pull mechanism includes an electric telescopic rod 30 fixed to the upper end of the pressure plate 20. The piston rod end of the electric telescopic rod 30 is fixedly connected to the lower end of the top plate 8. The piston rod of the electric telescopic rod 30 is located between two tensioning shafts 3 at the lower end of the top plate 8. The extension and retraction of the piston rod of the electric telescopic rod 30 can drive the two tensioning shafts 3 at the lower end of the top plate 8 to move. Through the cooperation of the resistance spring 29, the slider 18 and the tensioning shafts 3 on the slider 18, the tension of the limiting conveyor belt 4 can be guaranteed, thus ensuring operation.

[0035] In this embodiment, tensioning shafts 3 are rotatably sleeved on one side of the upper end of the pressure plate 20, the upper end of the slider 18, and both sides of the lower end of the top plate 8. A limiting conveyor belt 4 is sleeved on all four tensioning shafts 3 located on the same side. The opposite ends of the two limiting conveyor belts 4 are located at the upper end of the conveyor belt assembly 1, and the two limiting conveyor belts 4 are respectively located on one side of the two bent partitions 23. A lifting mechanism is provided on one of the top plate 8, and an elastic mechanism is provided on the other top plate 8. Lifting rods 5 are provided in both the lifting mechanism and the elastic mechanism. The upper ends of the two lifting rods 5 are rotatably connected to a flat scraper 2. The flat scraper 2 is located between the two limiting conveyor belts 4, at the upper end of the conveyor belt assembly 1. When the tensioning shafts 3 rotate, they can drive the limiting conveyor belts 4 to rotate, and the lower end of the tensioning shafts 3 can... A ring-shaped component is provided to restrict and limit the conveyor belt 4, preventing it from falling off. The movement of the limiting conveyor belt 4 can push the octagonal piece to pass better through the gap between the flat scraper 2 and the conveyor belt assembly 1, achieving a flat setting of the octagonal piece. Furthermore, the cooperation between the limiting conveyor belt 4 and the bending partition 23 at its front end can fully ensure that the octagonal piece is on the conveyor belt assembly 1, and limit the position of the octagonal piece between the two bending partitions 23 and the two limiting conveyor belts 4. At the same time, when the octagonal piece passes through the gap between the flat scraper 2 and the conveyor belt assembly 1, the limiting conveyor belt 4 can also play a certain limiting role, making it easier for the octagonal piece to follow the movement of the conveyor belt assembly 1, so that the near-infrared spectroscopy detection device 31 can photograph the octagonal piece passing under it, and improve the quality of the photographed near-infrared spectrum, providing more accurate information for detection.

[0036] In this embodiment, the lifting mechanism includes a lifting bolt 10 threaded onto one of the top plate members 8, a linkage plate 11 rotatably sleeved at the lower end of the lifting bolt 10, a lifting rod 5 rotatably sleeved at the upper end of the linkage plate 11, and a lifting rod 5 sleeved on one of the top plate members 8; the rotation of the lifting bolt 10 can control the position and height of the linkage plate 11 at the lower end of the lifting bolt 10, and the lifting rod 5 can push the flat scraper 2 to rise and fall, so as to control the distance between the flat scraper 2 and the conveyor belt in the conveyor belt assembly 1, so as to achieve flat octagonal.

[0037] In this embodiment, the elastic mechanism includes a through-hole 7 opened on another top plate 8, a linkage block 6 slidably installed in the through-hole 7, and another lifting rod 5 sleeved on the linkage block 6. A tension spring 9 is fixed together on the inner wall of the linkage block 6 and the through-hole 7. When the two top plates 8 move in opposite directions, increasing the distance between them, the flat scraper 2 will drive the lifting rod 5 in the linkage block 6 to push the linkage block 6 to move in the through-hole 7, so that the flat scraper 2 gradually operates in a direction perpendicular to the two top plates 8, adapting to the increase in the distance between the two top plates 8.

[0038] In this embodiment, the intermittent drive mechanism includes a drive motor assembly 32 installed on one side of the conveyor belt assembly 1. The output shaft of the drive motor assembly 32 is connected to an intermittent output assembly 33. A speed adjustment transmission assembly 34 is installed on the intermittent output assembly 33. The speed adjustment transmission assembly 34 is connected to the conveyor belt assembly 1. The drive motor assembly 32 can drive the intermittent output assembly 33 to operate, so that the final output component can achieve intermittent movement. This movement method is a prior art solution and does not need to be disclosed again. The speed adjustment transmission assembly 34 consists of two pulleys of different sizes and a belt sleeved on these two pulleys. The large pulley is connected to the output end of the intermittent output assembly 33 and moves synchronously. The small pulley is connected to the conveyor roller shaft in the conveyor belt assembly 1 to drive the conveyor belt assembly 1 to move. This can drive the octagonal intermittent movement on it, so that the octagonal intermittent movement passes through the near-infrared spectroscopy detection device 31, so that the near-infrared spectroscopy detection device 31 can improve the quality of the octagonal infrared spectroscopy detection image.

[0039] In this embodiment, the flat scraper 2 is inclined; by being inclined, the distance between the two limiting conveyor belts 4 can be reduced, thereby controlling the number of octagons passing between the two limiting conveyor belts 4, and ensuring that the near-infrared spectroscopy detection device 31 can accurately photograph the octagons.

[0040] In this invention, the top plate 8 is moved by the electric telescopic rod 30, so that one end of the limiting conveyor belt 4 is located at the upper end of the conveyor belt assembly 1. The distance between the limiting conveyor belt 4 and the conveyor belt assembly 1 will not cause the octagon to fall off, nor will it affect the transportation of the octagon. The octagon is placed on the conveyor belt assembly 1 between the two bent partitions 23. The bent partitions 23 can fully ensure that the octagon is on the conveyor belt assembly 1. And through the operation of the conveyor belt assembly 1, the octagon can move between the two limiting conveyor belts 4. By adjusting the distance between the flat scraper 2 and the conveyor belt assembly 1, the octagon can be changed from stacked to flat so that it can pass between the flat scraper 2 and the conveyor belt assembly 1. It can control the number of octagons passing between the two limiting conveyor belts 4, ensuring that the near-infrared spectral detection device 31 can accurately capture images of the octagons to obtain accurate near-infrared spectral images of the octagons.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
