Description

Technical Field

[0001] This invention belongs to the field of color sorting machine technology, and specifically relates to a color sorting machine for pepper production. Background Technology

[0002] During the harvesting, drying, and initial processing of Sichuan peppercorns, various impurities inevitably get mixed in, and peppercorns of different qualities also become mixed together. Traditional methods relying on manual visual sorting are extremely inefficient, labor-intensive, and prone to oversights due to fatigue. Using a color sorter ensures uniform color and purity, achieving higher market standards. In the color sorter, a vibrating feeder evenly arranges the peppercorns into a single layer, which fall into a channel. As the peppercorns fall freely, a high-resolution color camera scans them at high speed. The image processing system compares the captured images with preset "good" standards, instantly identifying defective peppercorns with abnormal color or shape. Once a defective peppercorn is identified, the system immediately instructs the solenoid valve to open the corresponding compression point. An air nozzle blows a high-speed airflow into the waste inlet, thus completing the color sorting process. Existing color sorters for Sichuan pepper production can basically meet the daily sorting needs. However, the spectral response characteristics of the image sensor in the vision camera drift with temperature. To ensure the stable operation of the image acquisition unit in the color sorter, a heat dissipation mechanism is needed for cooling. However, the heat dissipation structure in existing color sorters is mostly simply arranged on the shell, making it difficult to adjust the direction of the internal airflow, which affects the heat dissipation effect and may lead to incomplete sorting due to local overheating. At the same time, since Sichuan pepper sorting itself generates a lot of dust and particulate impurities, they are very easy to adhere to and block the heat dissipation air inlet, resulting in reduced airflow and unstable heat dissipation performance. Therefore, it is necessary to design a color sorter for Sichuan pepper production. Summary of the Invention

[0011] As a further optimization of the present invention, a support frame is provided on the side support, a collection pipe is provided on the support frame and connected to the collection hopper, and inclined material plates are evenly arranged on the support frame, with a separation air outlet opened at the bottom of the inclined material plates near the air outlet.

[0012] As a further optimization of the present invention, the main frame is provided with a separation shell, the bottom of the separation shell is provided with a first discharge shell and a second discharge shell respectively, and the first discharge shell and the second discharge shell are both sleeved in the through groove opened in the main frame.

[0014] The beneficial effects of this invention are as follows: 1. This invention uses a lead screw motor to drive the connecting lead screw to rotate, which in turn drives the moving platform on one side of the moving block to slide along the axis of the connecting lead screw. During the sliding process, the cleaning frame on the moving platform works together to clean the dust and particulate impurities intercepted on the filter plate, preventing impurities or dust from clogging the filter plate and causing airflow reduction and unstable heat dissipation performance.

[0015] 2. When the moving stage of the present invention moves to the top two sides of the visual inspection shell as the connecting screw rotates, the cleaning frame stops moving under the limiting action of the limiting frame. While the moving stage continues to move and compresses the support spring, it pushes the lower scraper to move down along the inclined slide groove, automatically scraping off the dust attached to the cleaning frame, ensuring the cleanliness of the cleaning frame itself, and preventing the cleaning frame from accumulating a layer of sticky dust during repeated scraping, which would cause the cleaning effect to gradually decrease.

[0016] 3. During the movement of the moving block along the connecting screw, the adjusting frame will move. Then, through the cooperation of the adjusting frame and the adjusting groove, the adjusting plate and the pull rod will swing back and forth, which will in turn drive the air guide plate to swing on the fixed strip to adjust the direction of the airflow. This allows the airflow passing through the vision inspection shell to completely cover the internal space of the vision inspection shell, avoiding local heat accumulation that could affect the image recognition effect of the vision camera.

[0017] 4. During the conveying process in the conveying shell, the hot air drawn out by the centrifugal fan is discharged into the conveying shell through the guide pipe and the hot air shell to dry the peppercorns. The peppercorns are dried while being pushed at low speed, which prevents the damp peppercorns from sticking together and affecting the sorting effect. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: Please refer to Figure 1-10A color sorter for Sichuan pepper production includes a main frame 1, with side supports symmetrically mounted on the main frame 1. An air blowing shell 4 and a vision inspection shell 6 are arranged obliquely between the side supports 2. The air blowing shell 4 has an air outlet 10, and air blowing nozzles are evenly arranged near the air outlet 10 within the air blowing shell 4. A connecting pipe is provided on the air blowing shell 4 to connect an external air source and the air blowing nozzles. A photoelectric receiver 8 and a vision camera 12 are fixedly mounted in the vision inspection shell 6. During the color sorting process, the photoelectric receiver 8 detects whether material is falling. If signal obstruction is detected, the vision camera 12 performs a high-speed scan, and the captured image is compared with a preset good product standard for color and shape sorting, rejecting defective products. Foreign objects in the product mainly include: pepper stalks, pepper thorns, snails, pepper seeds, hair, ribbons, and other malicious foreign objects such as insect eggs, insect carcasses, and rat droppings. The visual inspection shell 6 is equipped with an air vent cleaning mechanism 3 to prevent impurities from clogging the air inlet structure. The air vent cleaning mechanism 3 is equipped with an air direction adjustment mechanism 5 to regulate airflow direction. An air supply mechanism 7 is located at the bottom of the visual inspection shell 6. An upper support 11 is located between the side supports 2, and a raw material processing mechanism 9 is located on the upper support 11. The air supply mechanism 7 extracts hot air from the visual inspection shell 6 and transports it to the raw material processing mechanism 9. This, combined with the feeding process, provides preliminary drying of the peppers to prevent them from becoming damp and sticking together, thus affecting sorting. A support frame 14 is located on the side supports 2, and the support frame 14 is equipped with... A collection pipe 15 is connected to a collection hopper 16. A screen is installed in the collection hopper 16 facing the raw material processing mechanism 9 to prevent peppercorns from entering. A flange is installed on the collection pipe 15 to connect to an external air extraction device. During operation, the external air extraction device draws air out of the collection pipe 15, creating negative pressure in the collection hopper 16. Air at the opening of the collection hopper 16 then passes through the screen and enters the collection hopper 16. Inclined material plates 17 are evenly distributed on the support frame 14. A separation air outlet is located at the bottom of the inclined material plates 17 near the air outlet 10. During color sorting, the solenoid valve in the air nozzle opens, and high-pressure gas from the external air source is instantly ejected through the air nozzle and passes through the air outlet 10 and... The separation vent blows foreign objects and impurities out of the qualified peppercorns. A transparent observation plate is installed on the side of the visual inspection shell 6 facing the inclined material plate 17. The light signal of the photoelectric receiver 8 can pass through the transparent observation plate to detect the falling peppercorns, and at the same time, it is convenient for the visual camera 12 to collect images of the falling peppercorns. Multiple separation shells 18 are set on the main frame 1. The bottom of the separation shell 18 is respectively set with a first discharge shell 19 for discharging qualified peppercorns and a second discharge shell 20 for discharging foreign objects and impurities. The first discharge shell 19 and the second discharge shell 20 are both fitted into the through slot opened in the main frame 1. The top of the separation shell 18 is set with a first feed port and a second feed port. The first feed port and the second feed port are respectively connected to the first discharge shell 19 and the second discharge shell 20.After being dried by the raw material processing unit 9, the Sichuan peppercorns fall onto the inclined material plate 17 and slide down the slope. During this descent, the photoelectric receiver 8 and the vision camera 12 work together to collect image information. If a product is determined to be defective, the high-speed solenoid valve on the air nozzle in the air blowing shell 4 opens and closes instantaneously once. The instantaneous airflow blows the defective product to the second feed inlet, and then it is discharged through the second discharge shell 20. Meanwhile, the good Sichuan peppercorns enter the first feed inlet and are discharged through the first discharge shell 19.

[0022] Please see Figure 1 and Figure 5-10 The air vent cleaning mechanism 3 includes a connecting screw 31 rotatably connected between side supports 2 via bearings. A movable block 32 is provided on the connecting screw 31, and the movable block 32 is connected to the connecting screw 31 by a ball nut embedded inside. A screw motor 33 for driving the connecting screw 31 to rotate is provided on one side of the side support 2. The movable block 32 is fixed on one side of the moving platform 34. Cleaning frames 35 slide through both sides of the moving platform 34. The cleaning frames 35 are attached to the filter plate 13. The filter plate 13 is a perforated mesh plate and a precision woven metal material. The double-layer structure consists of a perforated mesh plate to intercept dust and large particles, while the precision woven metal mesh intercepts and holds fine dust particles, preventing them from entering the vision inspection housing 6 and damaging the photoelectric receiver 8 and vision camera 12. A filter plate 13 is fixed to the vision inspection housing 6. A support spring 36 is provided between the cleaning frame 35 and the moving stage 34. A guide rod on one side of the cleaning frame 35 is slidably connected to a limiting frame 37, which is fixed to the vision inspection housing 6 and restricts the movement path of the cleaning frame 35. The 5 is equipped with a self-cleaning component, which includes inclined slide grooves 301 on both sides of the scraper 35. Side sliders 302 are slidably connected in the inclined slide grooves 301. The side sliders 302 are fixedly installed on the lower scraper 38. Three support rails 39 are evenly arranged on one side of the lower scraper 38. The support rails 39 are slidably connected to the slide grooves on the moving platform 34. When the lead screw motor 33 drives the connecting lead screw 31 to rotate, it can drive the moving platform 34 on one side of the moving block 32 to slide along the axis of the connecting lead screw 31. During the sliding process, it cooperates with the slide platform 34. The cleaning frame 35 is used to clean the dust and particulate impurities intercepted on the filter plate 13. After the moving stage 34 moves to the top two sides of the vision inspection housing 6, the cleaning frame 35 stops moving under the limiting action of the limiting frame 37. The moving stage 34 continues to move and compresses the support spring 36. The side slider 302 pushes the lower scraper 38 to move down along the inclined slide groove 301, automatically scraping off the dust attached to the cleaning frame 35. This ensures the cleanliness of the cleaning frame 35 itself and prevents the cleaning frame 35 from accumulating a layer of sticky dust during repeated scraping, which would cause the cleaning effect to gradually decrease.

[0023] Please see Figure 9-10The wind direction adjustment mechanism 5 includes an adjustment frame 51 fixed to the bottom of the moving block 32. The adjustment frame 51 is slidably connected to a through groove in the vision inspection housing 6. The vision inspection housing 6 is provided with a sealing mechanism to seal the through groove and prevent dust and impurities from being introduced into the through groove as an air inlet. The sealing mechanism includes tensioning wheels 57 rotatably connected to both ends inside the vision inspection housing 6. A sealing strip 58 is tensioned on the tensioning wheels 57. The adjustment frame 51 is fixedly inserted through one side of the sealing strip 58, and the top of the sealing strip 58 is attached to the bottom of the through groove in the vision inspection housing 6. As the adjustment frame 51 moves with the moving block 32, the sealing strip 58 rotates around the tensioning wheel 57, thus keeping the through groove closed. The bottom of the adjustment frame 51 is slidably connected to an adjustment groove 52 with a continuous curved path. The adjustment groove 52 is opened on an adjustment plate 53, which is fixed to the pull rod. On the pull rod 54, a guide vane 55 is rotatably connected between the pull rods 54. The two ends of the guide vane 55 are rotatably connected to the fixing strip 56. The fixing strip 56 is fixed inside the vision inspection housing 6. When the moving block 32 moves along the connecting screw 31, it will drive the adjusting frame 51 to move. Then, through the cooperation of the adjusting frame 51 and the adjusting groove 52, it will drive the adjusting plate 53 and the pull rod 54 to swing back and forth. This will drive the guide vane 55 to swing on the fixing strip 56 to adjust the direction of the airflow. This will allow the airflow passing through the vision inspection housing 6 to completely cover the internal space of the vision inspection housing 6, avoiding the accumulation of local heat that may affect the image recognition effect of the vision camera 12.

[0024] Please see Figure 1-3 and Figure 5-6The air supply mechanism 7 includes centrifugal fans 71 symmetrically fixed to the bottom of the vision inspection housing 6. An exhaust housing 72 is mounted on the centrifugal fan 71 and fixed to the vision inspection housing 6. The vision inspection housing 6 and the exhaust housing 72 are interconnected. A guide pipe 73 is provided at the output end of the centrifugal fan 71. During operation, the centrifugal fan 71 can extract hot air from the vision inspection housing 6 through the exhaust housing 72. The raw material processing mechanism 9 includes multiple conveying housings 91 fixed to the upper support 11. A hot air housing 96 is provided between the conveying housings 91. An electric heating wire is embedded inside the hot air housing 96. An air inlet is provided at the connection between the conveying housing 91 and the hot air housing 96. The hot air housing 96 and the guide pipe 73... The conveyor housing 91 is interconnected, and a temperature sensor is installed on its inner wall to detect the internal temperature environment. A spiral conveyor rod 92, made of nylon, is rotatably connected to the conveyor housing 91 via bearings. This ensures food safety while preventing damage to the peppercorns. A feed hopper 90 is located at the top of one end of the conveyor housing 91, and a discharge hopper is located at the bottom of the other end. A feeding frame 93 is mounted on the side support 2. A vibrating conveyor frame 94 and a discharge shell 95 are evenly arranged on the top of the feeding frame 93. The discharge port at the bottom of the discharge shell 95 is located above the vibrating conveyor frame 94, and the square discharge port at the top of the discharge shell 95 is located below the discharge hopper. A vibrating conveyor frame 94 is equipped with a vibrating motor. Peppers entering the vibrating conveyor frame 94 from the discharge shell 95 will move forward under the directional vibration of the vibrating motor. A mounting frame 97 is fixed to the upper support 11. A transmission wheel 98 is rotatably connected to the mounting frame 97. A transmission belt 99 is tensioned on the transmission wheel 98. A transmission chain 100 is fixedly installed on the inner wall of the transmission belt 99. The transmission chain 100 is connected to a sprocket 101, which is fixed to one end of the screw conveyor rod 92. A conveyor motor 102 is fixedly installed on the upper support 11. A reducer is installed on the conveyor motor 102. The input end of the reducer is connected to the output end of the conveyor motor 102, and the output end of the reducer is connected to one of the... The rotational torque delivered by the output end of the conveyor motor 102 can be output to the drive wheel 98 through the reducer. During the operation of the drive wheel 98 and the drive belt 99, the drive chain 100 in the drive belt 99 can drive the sprocket 101 to rotate, thereby driving the spiral conveyor rod 92 to move, pushing the peppercorns put into the feed hopper 90 to the discharge hopper, and then entering the vibrating conveyor frame 94 and moving forward with the vibration. The intercepting mesh plate on the collection hopper 16 is located on the side and above the vibrating conveyor frame 94. The dust generated during the vibration and forward movement of the peppercorns will pass through the intercepting mesh plate and enter the collection hopper 16 under the negative pressure of the external air extraction equipment, until it falls onto the inclined material plate 17 for color sorting.During conveying in the conveying shell 91, a temperature sensor in the conveying shell 91 collects the temperature in real time. When the temperature exceeds the threshold, the heating wire is de-energized, and the hot air drawn out by the centrifugal fan 71 is discharged into the conveying shell 91 through the guide pipe 73 and the hot air shell 96 to dry the peppercorns. The peppercorns are dried during the low-speed pushing process to prevent the damp peppercorns from sticking together and affecting the sorting effect. When the temperature is below the threshold, the heating wire heats up to adaptively compensate for the temperature and ensure the drying effect.

[0025] It should be noted that, in the operation of this color sorter for Sichuan pepper production, the Sichuan peppers to be sorted are first fed into the conveying shell 91 from the feed hopper 90. The centrifugal fan 71 operates to extract hot air from the vision inspection shell 6. The ambient air, after passing through the filter plate 13, is replenished into the vision inspection shell 6 to continue exchanging heat with the photoelectric receiver 8 and the vision camera 12. The hot air extracted by the centrifugal fan 71 is discharged into the conveying shell 91 through the guide pipe 73 and the hot air shell 96 to dry the Sichuan peppers. The Sichuan peppers are dried while being pushed at low speed to prevent the damp peppers from sticking together and affecting the sorting effect. The rotational torque delivered by the output end of the conveying motor 102 can be output to the transmission wheel 98 through the reducer, and then driven by the transmission belt 99 and the transmission chain 100. The sprocket 101 and the spiral conveyor rod 92 move, pushing the peppercorns towards the discharge hopper. The peppercorns that have been conveyed into the discharge shell 95 will come to the vibrating conveyor frame 94 and move forward with the vibration until they fall onto the inclined material plate 17 to form a material curtain. During the color sorting process, the photoelectric receiver 8 detects the falling material. After detecting signal obstruction, the vision camera 12 scans it at high speed and compares the captured image with the preset good product standard to perform color sorting and shape sorting, remove foreign objects from the product, and determine that it is a defective product. The high-speed solenoid valve on the air nozzle in the air blowing shell 4 opens and closes once instantaneously. The instantaneous airflow blows the defective product to the second feed port and then discharges it through the second discharge shell 20, while the good peppercorns enter the first feed port and are discharged through the first discharge shell 19.

[0026] During the color sorting process, the lead screw motor 33 drives the connecting lead screw 31 to rotate, which in turn drives the moving stage 34 to slide along the axis of the connecting lead screw 31. This causes the cleaning frame 35 to scrape the dust and particulate impurities intercepted on the filter plate 13, preventing impurities or dust from clogging the filter plate 13 and causing airflow reduction and unstable heat dissipation performance. When the moving stage 34 moves to the top two edges of the vision inspection housing 6 as the connecting lead screw 31 rotates, the cleaning frame 35 stops moving. The moving stage 34 continues to move and compresses the support spring 36. At the same time, the side slider 302 pushes the lower scraper 38 down along the inclined slide groove 301, automatically scraping away the dust attached to the cleaning frame 35. Meanwhile, the moving block 32 moves and drives the adjusting frame 51 to move. Through the cooperation of the adjusting frame 51 and the adjusting groove 52, the air guide plate 55 swings to adjust the direction of airflow, so that the airflow passing through the vision inspection housing 6 can completely cover the internal space of the vision inspection housing 6, avoiding local heat accumulation that affects the image recognition effect of the vision camera 12.

[0027] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
