Description

Technical Field

[0001] This invention relates to the field of cotton testing, and more particularly to an intelligent testing device for fine-grained classification of cotton color grades. Background Technology

[0002] Cotton color grade is one of the main quality parameters for grading and classifying cotton. Rd and +b are color parameters obtained based on HVI testing. Rd (reflectance percentage) represents the brightness or darkness of the sample (i.e., Rd=100 for pure white and Rd=0 for pure black), while +b measures the yellowness of the sample. Cotton Rd values ​​are typically between 40 and 80; while +b values ​​are typically between 5 and 17. The higher the +b value, the greater the yellowness of the cotton. Generally, fully opened cotton has an Rd ≥ 70 and a +b ≤ 9. Cotton color grade is affected by cotton variety, weather conditions after the bolls open, the harvesting process, and the ginning process. A chromaticity diagram can be used to convert various combinations of grayscale and yellowness into chromaticity values ​​based on the Rd and +b values.

[0003] In sensory inspection, the final results are subject to subjective errors due to various factors, including the overall inspection level of the inspectors, their sensitivity to color, their grading mindset, their methods, the storage and use of physical standards, and their own qualities and psychological factors. Instrument testing is relatively stable, less affected by environmental factors, and yields more objective results, with standardized color charts and permissible error ranges. However, when using instruments to inspect and classify cotton, inspectors typically collect and analyze images of the cotton on the sample surface after sampling. If the cotton is unevenly distributed during sampling, resulting in obvious stratification, the accuracy of this inspection method will be greatly reduced, the cotton data will be less reliable, and consequently, the grading and classification of cotton will be inaccurate.

[0004] Furthermore, since the cotton on the sample surface is image-acquired and analyzed after sampling, the container carrying the cotton does not have any measures in place to prevent the cotton from falling out of the container during the transport process. The cotton falls into the gaps in the transport equipment, causing the cotton to get tangled inside the equipment, resulting in equipment malfunction and preventing the cotton inspection work from proceeding normally. Summary of the Invention

[0005] To overcome the shortcomings of using instruments to inspect and classify cotton, which only detect a portion of the sample cotton, resulting in weak reference value of the cotton data and inaccurate grading and classification, and the problem that cotton falling into the gaps of the transmission equipment can cause cotton to get tangled inside the equipment, leading to equipment malfunction and preventing the cotton inspection work from proceeding normally, this invention provides an intelligent detection device for fine-grained classification of cotton color.

[0009] As a further preferred embodiment, the anti-drop system includes airbags, squeezing rods, air blowing pipes, first one-way valves, a cooling suction assembly, and a collection assembly. Several airbags are fixedly attached to the inside of the inspection cabinet. Each airbag has a squeezing rod fixedly attached to its upper side. The front of each squeezing rod is curved downwards. Several airbags are connected together to an air blowing pipe to prevent cotton from falling from the loading tray. A first one-way valve is fixedly attached to the left and right sides of the air blowing pipe. Both first one-way valves are configured to open towards the center of the air blowing pipe and close towards both ends of the air blowing pipe. A cooling suction assembly for heat exchange and cooling of the grading lamps is fixedly attached to the inside of the inspection cabinet. A collection assembly for collecting cotton scraps and which is easy to disassemble is provided on the cooling suction assembly.

[0010] As a further preferred option, each air inlet on the air blowing pipe faces the center of the material tray.

[0011] As a further preferred embodiment, the cooling suction assembly includes a transfer pipe, a heat exchanger, and a second one-way valve; several transfer pipes are fixedly connected to the upper side of each airbag; a heat exchanger for cooling the grading lamp is fixedly connected to the inside of the inspection cabinet; several suction holes are opened on the heat exchanger facing the grading lamp; several transfer pipes are fixedly connected to the lower side of the heat exchanger; a second one-way valve is fixedly connected to each transfer pipe; each second one-way valve is configured to close when facing upwards and open when facing downwards.

[0012] As a further preferred option, several through holes are provided on both the left and right sides of the grading lamp; each through hole is located between two adjacent lamp tubes on the grading lamp, and several through holes are connected to the air extraction hole.

[0013] As a further preferred embodiment, it also includes an air outlet; the upper middle part of the air outlet is connected to an air outlet to prevent cotton from blocking the camera from taking pictures; the upper part of the air outlet is arranged in a ring around the front of the camera, and each air outlet on the air outlet faces downwards from the camera.

[0015] As a further preferred option, the interception net is arranged in a shape that gradually bulges towards the center from the front and rear sides.

[0016] The present invention has the following advantages: The present invention realizes that the sample cotton on the upper surface of the material tray can be turned up by the suction device, which prevents the equipment from only taking pictures of the upper surface of the sample cotton for inspection, avoids low inspection accuracy, and improves the accuracy of cotton inspection. The protrusions push out the cotton adhering to the filter screen, preventing the cotton adhering to the filter screen from clogging the suction device and ensuring the normal operation of cotton inspection. The push rod drives the elastic membrane to seal the sliding groove, preventing airflow from entering the sliding groove when the suction device is drawing in, thus preventing cotton from entering the suction device from the sliding groove, thereby preventing the suction device from being blocked by cotton. At the same time, it prevents the suction effect of the suction device on cotton from being reduced, further ensuring the normal operation of cotton inspection work. Air is blown from the back of the tray to the front through the air nozzle on the air pipe to prevent the cotton in the tray from being blown out to the back of the tray when the suction device is closed. This avoids the cotton falling into the gaps on the conveyor belt and causing the conveyor belt to get tangled with the cotton, thereby avoiding equipment malfunctions and ensuring the normal operation of cotton inspection. By blowing air through the air outlet to the lower side of the camera, the floating cotton lint is guided downwards to prevent it from obstructing the camera and avoid abnormal images of the cotton samples, thus ensuring the normal operation of cotton inspection. The heat exchanger is used to evacuate and dissipate heat from the outer surface of the grading lamp to prevent the grading lamp from getting too hot and generating static electricity. This also prevents the grading lamp from actively attracting cotton lint floating inside the inspection cabinet, thus preventing the grading lamp from being blocked by cotton lint and ensuring the lighting effect during cotton inspection. The cotton lint transported through the transmission tube is intercepted by an interception net to prevent it from entering the air bladder, thus avoiding blockage of the air blowing and air outlet pipes and ensuring the normal operation of cotton inspection.

[0020] Example 1 like Figures 3-7 As shown, a cotton color grade fine-grained classification intelligent detection device includes an inspection cabinet 1, a conveyor belt 2, and a camera 3; the conveyor belt 2 is set in the middle of the inspection cabinet 1; several cameras 3 are installed inside the inspection cabinet 1. It also includes a grading light 4, a suction device 5, a filter 6, a pushing assembly, and an anti-drop system; the grading light 4 is installed inside the inspection cabinet 1; the suction device 5 is installed at the front inside the inspection cabinet 1; the suction device 5 is connected to an external air pump; the filter 6 is installed on the suction device 5; the pushing assembly is installed inside the inspection cabinet 1; the anti-drop system is installed at the rear inside the inspection cabinet 1; the sample cotton on the upper surface of the material tray is turned up by the suction device 5, and then the camera 3 takes pictures of the inside of the sample cotton in the material tray for inspection, preventing the equipment from only taking pictures of the upper surface of the sample cotton for inspection, avoiding low inspection accuracy, and improving the accuracy of cotton inspection.

[0021] The pushing assembly includes a connecting rod 101, a pushing rod 102, a protrusion 10201, a first magnet 103, and a second magnet 104; two symmetrical connecting rods 101 are rotatably connected inside the inspection cabinet 1 via torsion springs; two symmetrical sliding grooves 5001 are provided on the suction device 5; a pushing rod 102 is rotatably connected between the two connecting rods 101; the pushing rod 102 is located inside the suction device 5, and the left and right ends of the pushing rod 102 respectively pass through adjacent sliding grooves 5001; the pushing rod The surface of 102 is provided with several protrusions 10201; several first magnets 103 are rotatably connected to the outside of each sliding groove 5001 via a torsion spring; several second magnets 104 are rotatably connected to the inside of each sliding groove 5001 via a torsion spring; the suction device 5 is flipped to drive the push rod 102 to roll inside the suction device 5, and then the cotton adhering to the filter screen 6 is pushed out through the protrusions 10201, preventing the cotton adhering to the filter screen 6 from clogging the suction device 5, and ensuring the normal operation of the cotton inspection work.

[0022] It also includes an elastic membrane 105; the suction device 5 has two symmetrical movable cavities 5002; each movable cavity 5002 is movably connected to an elastic membrane 105; the two elastic membranes 105 are rotatably connected to the left and right ends of the push rod 102 respectively; the push rod 102 drives the elastic membranes 105 to block the sliding groove 5001, preventing airflow from entering the sliding groove 5001 when the suction device 5 is suctioning, avoiding cotton from entering the suction device 5 from the sliding groove 5001, thus preventing the suction device 5 from being blocked by cotton, and at the same time, preventing the suction effect of the suction device 5 from being reduced due to airflow dispersion, further ensuring the normal operation of cotton inspection.

[0023] It also includes a drive assembly, which includes a slide rail 106, an electric slider 107, and a motor 108; two left-right symmetrical slide rails 106 are fixedly connected inside the inspection cabinet 1; each slide rail 106 is arc-shaped; an electric slider 107 is slidably connected to each slide rail 106; the two electric sliders 107 are fixedly connected to the grading lamp 4; a motor 108 is fixedly connected to the front right side of the inspection cabinet 1; the output end of the motor 108 is fixedly connected to the lower right side of the suction device 5.

[0024] The specific process by which this invention enhances the accuracy of cotton inspection is as follows: When fine particle size testing of cotton color grades is required, the staff first weighs the sample cotton and places it in a loading tray, then places the tray on conveyor belt 2. The conveyor belt 2 transports the sample cotton to be tested into the testing cabinet 1. An electric slider 107 drives the grading lamp 4 to slide in an arc on the slide rail 106, illuminating the surface of the sample cotton from multiple angles. A camera 3 then photographs the surface of the sample cotton for inspection. After the sample cotton surface is tested, a motor 108 drives the suction device 5 to rotate, causing the suction device 5, initially perpendicular to the surface of the conveyor belt 2, to close and... The sample cotton is placed on the loading tray, making the suction device 5 parallel to the surface of the conveyor belt 2. Then, an external air pump is used to evacuate the sample cotton in the loading tray, causing the sample cotton in the loading tray to adhere to the filter screen 6. Then, the motor 108 drives the suction device 5 to rotate, causing the suction device 5 to pick up the sample cotton and reset it, revealing the inside of the sample cotton in the loading tray. Then, the camera 3 takes pictures of the inside of the sample cotton in the loading tray and the sample cotton picked up by the suction device 5 for inspection, preventing the equipment from only taking pictures of the upper surface of the sample cotton for inspection, avoiding low inspection accuracy, and improving the accuracy of cotton inspection.

[0025] The suction device 5 flips, causing the push rod 102 to roll on the sliding groove 5001. During this rolling process, the push rod 102 pushes open the first magnet 103 and the second magnet 104 one by one. After passing each of the first magnet 103 and the second magnet 104, the magnets are reset by a torsion spring, stabilizing the sliding groove 5001 and preventing deformation. This ensures the push rod 102 can properly clean the cotton on the filter screen 6. When the suction device 5 picks up the cotton and flips it upwards, the push rod 102 rolls downwards in the sliding groove 5001 near the front of the inspection cabinet 1, preventing the cotton adhering to the filter screen 6 from being pushed out by the push rod 102 and falling back into the loading tray. When the suction device 5 is tilted downwards, the external air pump on the suction device 5 stops working, and the push rod 102 rolls upwards in the sliding groove 5001 on the side near the rear of the inspection cabinet 1. The protrusion 10201 pushes out the cotton adhering to the filter screen 6, preventing the cotton adhering to the filter screen 6 from clogging the suction device 5, thus ensuring the normal operation of the cotton inspection work. During the rolling process of the push rod 102, the push rod 102 drives the elastic membrane 105 to seal the sliding groove 5001, preventing the airflow from entering the sliding groove 5001 when the suction device 5 is suctioning, and preventing cotton from entering the suction device 5 from the sliding groove 5001, thereby preventing the suction device 5 from being blocked by cotton. At the same time, it prevents the suction effect of the suction device 5 from being reduced, further ensuring the normal operation of the cotton inspection work.

[0026] Example 2 Based on Example 1, such as Figures 8-11As shown, the anti-fall system includes an airbag 201, a compression rod 202, an air blowing pipe 203, a first one-way valve 204, a cooling suction assembly, and a collection assembly. Two symmetrically arranged airbags 201 are fixedly attached to the rear inner side of the inspection cabinet 1. A compression rod 202 is fixedly attached to the upper side of each airbag 201. The front of each compression rod 202 is curved downwards to reduce mechanical wear. An air blowing pipe 203 is fixedly attached to the lower side of both airbags 201. A first one-way valve 204 is fixedly attached to the left and right sides of the air blowing pipe 203. Both first one-way valves 204 are oriented towards… The air blowing pipe 203 is opened on one side of the center and closed at both ends towards the air blowing pipe 203; a cooling suction assembly is fixedly connected to the rear of the inner side of the inspection cabinet 1; a collection assembly is provided on the cooling suction assembly; the gas in the air bag 201 is squeezed towards the air blowing pipe 203 by the squeezing rod 202, and then blown out from the rear side of the loading tray through the air blowing port on the air blowing pipe 203, preventing the cotton in the loading tray from being blown out towards the rear side of the loading tray when the suction device 5 is closed, avoiding the cotton from falling into the gaps on the conveyor belt 2 and causing the conveyor belt 2 to wrap around the cotton, thereby avoiding equipment malfunction and further ensuring the normal operation of cotton inspection.

[0027] Each air outlet on the air blowing pipe 203 faces the center of the material tray; this prevents the air blowing pipe 203 from blowing cotton from the rear left and rear right sides of the material tray into the gaps on the conveyor belt 2, thus avoiding equipment malfunctions and further ensuring the normal operation of cotton inspection.

[0028] The cooling suction assembly includes a transmission pipe 206, a heat exchanger 207, and a second one-way valve 208. Two transmission pipes 206 are fixedly connected to the upper side of each airbag 201. A heat exchanger 207 is fixedly connected to the rear inner side of the inspection cabinet 1. Several suction holes 20701 are opened on the heat exchanger 207 facing the grading lamp 4. Several transmission pipes 206 are fixedly connected to the lower side of the heat exchanger 207. A second one-way valve 208 is fixedly connected to each transmission pipe 206. Each second one-way valve 208 is configured to close upwards and open downwards. The suction force generated when the airbag 201 expands is transmitted from the transmission pipe 206 to the heat exchanger 207, evacuating and dissipating heat from the outer surface of the grading lamp 4. This prevents the grading lamp 4 from overheating and generating static electricity, and avoids the grading lamp 4 actively attracting cotton lint floating inside the inspection cabinet 1, thus preventing the grading lamp 4 from being blocked by cotton lint and ensuring the lighting effect during cotton inspection.

[0029] The grading lamp 4 has several through holes 4001 on both the left and right sides; each through hole 4001 is located between two adjacent lamp tubes on the grading lamp 4, and the through holes 4001 are connected to the air extraction hole 20701; through the through holes 4001, the heat exchanger 207 can suck up the cotton lint adhering between two adjacent lamp tubes on the grading lamp 4, further preventing the grading lamp 4 from being blocked by cotton lint and ensuring the lighting effect during cotton inspection.

[0030] It also includes an air outlet pipe 205; the upper middle part of the air blowing pipe 203 is connected to the air outlet pipe 205; the upper part of the air outlet pipe 205 is arranged in a ring around the front side of the camera 3, and each air outlet on the air outlet pipe 205 faces downward of the camera 3; by blowing air through the air outlet pipe 205 to the lower side of the camera 3, the floating cotton lint is guided downward of the camera 3 to prevent the floating cotton lint from blocking the camera 3, avoid abnormal images of the sample cotton, and further ensure the normal operation of cotton inspection.

[0031] The specific process of preventing falling and obstruction in this invention is as follows: When the suction device 5 draws in the cotton and it falls downwards, the upper part of the suction device 5 contacts the front part of the extrusion rod 202 and squeezes it downwards. The front part of the extrusion rod 202 is designed with a downward-curving arc shape, reducing mechanical wear between the upper part of the suction device 5 and the front part of the extrusion rod 202, thus extending the service life of the equipment. The extrusion rod 202 presses down on the air bladder 201, at which point the first one-way valve 204 opens and the second one-way valve 208 closes, allowing the compressed gas inside the air bladder 201 to be transmitted to the air blowing pipe 203 and the air outlet pipe 205. This, in turn, directs the gas from the air blowing pipe 203 towards the material. Each air outlet in the center of the tray blows air from the rear of the tray forward. When the suction device 5 is closed, the space between the suction device 5 and the tray decreases, and the airflow between the suction device 5 and the tray is discharged to the rear of the tray. This prevents the discharged airflow from blowing the cotton in the tray towards the rear of the tray, avoiding cotton falling into the gaps on the conveyor belt 2 and causing the conveyor belt 2 to become entangled with cotton, thus preventing equipment malfunctions and ensuring the normal operation of cotton inspection. At the same time, air is blown under the camera 3 through the air outlet pipe 205 to guide floating cotton dust downwards from the camera 3, preventing it from drifting. Floating cotton lint obstructs the camera 3, preventing abnormal images of the cotton samples and further ensuring the normal operation of cotton inspection. When the suction device 5 flips back to its original position, the air bladder 201 expands and resets. At this time, the grading lamp 4 moves to the lower side of the heat exchanger 207. Simultaneously, the first one-way valve 204 closes and the second one-way valve 208 opens. The suction force generated by the expansion of the air bladder 201 is transmitted to the heat exchanger 207 through the transmission pipe 206, and then the outer surface of the grading lamp 4 is cooled by suction through the air extraction hole 20701 to prevent the grading lamp 4 from overheating and generating static electricity, thus avoiding the formation of static electricity. The grade lamp 4 actively absorbs cotton lint floating inside the inspection cabinet 1. Hot air drawn from the outer surface of the grade lamp 4 is compressed by the air bag 201 and blown out from the rear side of the loading tray, which helps to dry the cotton inside the rear of the loading tray and facilitates subsequent cotton inspection. At the same time, through several through holes 4001, the heat exchanger 207 sucks up the cotton lint adhering between two adjacent lamp tubes on the grade lamp 4. The collection component intercepts and collects the cotton lint transported in the transmission pipe 206, preventing the grade lamp 4 from being blocked by cotton lint and ensuring the lighting effect during cotton inspection.

[0032] Example 3 Based on Example 2, such as Figure 1 , Figure 2 and Figures 8-12 As shown, the collection assembly includes a collector 301 and an interceptor net 302; two collectors 301 are fixedly attached to the rear inner side of the inspection cabinet 1; each collector 301 is a hollow structure; each collector 301 is connected to the adjacent transmission pipe 206; an interceptor net 302 is fixedly attached inside each collector 301; the interceptor net 302 intercepts the cotton lint transmitted in the transmission pipe 206, preventing the cotton lint from entering the air bag 201, avoiding the air blowing pipe 203 and the air outlet pipe 205 from being blocked by cotton lint, and ensuring the normal operation of cotton inspection.

[0033] The interception net 302 is designed to gradually bulge towards the center from the front and rear sides. The interception net 302, which gradually bulges towards the center from the front and rear sides, guides the cotton lint entering the collector 301 towards the front and rear inner sides of the collector 301, preventing the cotton lint from clogging the interception net 302. This avoids reducing the heat dissipation effect of the heat exchanger 207 on the grading lamp 4 and the collection effect of the cotton lint attached to the lamp tube of the grading lamp 4, and further ensures the normal operation of cotton inspection.
