Description

Technical Field

[0001] This utility model relates to the field of color sorter anti-jumping technology, specifically to a color sorter anti-jumping material device. Background Technology

[0002] Color sorters are devices that automatically separate defective materials from granular materials based on differences in their optical properties using photoelectric detection technology. Currently, color sorters are used in the fields of bulk materials or packaging industrial products, food quality testing and grading. Waterfall color sorters are currently the most widely used type of color sorter. However, belt color sorters currently suffer from problems when sorting nearly round materials, as the materials are difficult to stabilize on the belt and may jump or roll, thus affecting identification and reducing color sorting accuracy. Therefore, anti-jumping devices are needed to prevent materials from jumping or rolling.

[0003] In the prior art, a color sorter anti-jumping device with publication number "CN221714951U" relates to the field of color sorter anti-jumping technology. This utility model includes a machine body with two vertical plates and a feeding hopper. The two vertical plates are fixedly installed on the surface of the machine body, and the feeding hopper is fixedly installed between the two vertical plates. A discharge hopper is located between the two vertical plates. When the rotating roller rotates, it drives multiple spreading plates to rotate. The spreading plates can flatten the material transported on the conveyor belt, preventing material accumulation and keeping the material stable during transport, reducing jumping or rolling phenomena, facilitating material identification, and helping to reduce the accuracy error of the color sorter during color sorting. The striking rod can intermittently contact the bottom of the discharge hopper, and in conjunction with the connecting block and telescopic spring, it can cause the discharge hopper to vibrate and discharge material, improving discharge efficiency. Furthermore, during vibration, the material is more easily dispersed, reducing the probability of material accumulation.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] During use, the aforementioned device can flatten the materials transported on the conveyor belt using a flat plate, preventing material accumulation and ensuring stability during transport, preventing jumping or rolling. However, since the materials vary in size, even when the flat plate is adjusted to a suitable height, smaller particles may still pile up. During color sorting, good quality materials will block defective materials, affecting the color sorter's identification of materials and consequently impacting the sorting accuracy, making it impossible to separate defective materials. Utility Model Content

[0006] The purpose of this invention is to provide a color sorter anti-jumping device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A color sorter anti-jumping device includes a workbench, several support legs fixedly installed below the workbench, a color sorter housing fixedly installed on the side of the workbench, a control panel and an air compressor fixedly installed on the outer wall of the color sorter housing, a partition fixedly installed inside the color sorter housing, LED lights and several optical lenses fixedly installed on both sides of the partition inside the color sorter housing, a spray valve fixedly inserted below the optical lens, the spray valve being connected to the air compressor through a connecting pipe, and an inclined plate fixedly installed below the color sorter housing.

[0009] The workbench is equipped with a filtration mechanism capable of separating materials by size.

[0010] The workbench is equipped with an anti-jump mechanism to prevent the separated material from jumping.

[0011] Preferably, the filtration mechanism includes a filter box fixedly mounted on a workbench, a feed hopper fixedly connected to the filter box, several sliding rods fixedly mounted inside the filter box, a filter screen and a receiving plate slidably mounted on the sliding rods respectively, a rotating shaft rotatably mounted below the filter screen and the receiving plate inside the filter box, a cam fixedly mounted on the rotating shaft, two pulleys fixedly mounted on the outside of the filter box on the two rotating shafts, a belt mounted on the two pulleys, and a second pulley fixedly mounted on one of the rotating shafts outside the filter box;

[0012] The filter box has two discharge ports, and a chute is fixedly installed at the discharge port. The filter screen and the receiving plate are both located above the chute.

[0013] Preferably, the anti-jump mechanism includes three parallel baffles fixedly mounted on the worktable. A drive shaft and a driven shaft are rotatably inserted into the three baffles. A drive roller is fixedly mounted between the baffles on the drive shaft, and a driven roller is fixedly mounted between the baffles on the driven shaft. A conveyor belt is fitted onto the drive roller and the driven roller. A motor is fixedly mounted at one end of the drive shaft, and the motor is fixedly mounted on the baffle. A pulley three is fixedly mounted at the end of the drive shaft away from the motor. A belt two is fitted onto the pulley three and the pulley two. A smoothing component for leveling the material is provided on the conveyor belt.

[0014] Preferably, the smoothing component includes a plurality of movable slots opened on the baffle, in which a threaded rod is rotatably engaged, and in the movable slots of two adjacent baffles, scrapers that are threadedly engaged with the threaded rod are movably engaged.

[0015] Preferably, the filter screen is positioned above the receiving plate, and springs are fitted around both the filter screen and the receiving plate on the slide rod. A limit plate is fixedly positioned below the springs on the slide rod.

[0016] Preferably, a support plate is fixedly provided between two adjacent baffles, the support plate being located below the conveyor belt on the side near the scraper and in contact with the conveyor belt.

[0017] Preferably, the LED light, optical lens, and spray valve are all electrically connected to the control panel.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This device, through the setting of the filtration mechanism, can first filter and classify materials into two categories of different sizes, which then fall onto two conveyor belts respectively. By adjusting the distance between the scraper in the smoothing component and the conveyor belt according to the size of the different materials on the conveyor belt, the two different sizes of materials on the conveyor belt can be smoothed into a single layer without stacking. Finally, the materials are conveyed to the color sorter through the conveyor belt, where the color sorter picks out the defective products, preventing defective products from being mistakenly selected into good products, thereby improving the screening accuracy of the color sorter.

[0020] 2. While the motor drives the conveyor belt to rotate, it drives the rotating shaft in the filter box to rotate through the pulley three and belt two on the drive shaft. This causes the cam to rotate under the filter screen and receiving plate, making the filter screen and receiving plate vibrate up and down, thereby accelerating the filtration of materials and allowing the materials to fall onto the conveyor belt as quickly as possible, thus improving the operating efficiency of the device.

[0021] 3. The support plate can support the conveyor belt and the material on it, preventing the conveyor belt from deforming and increasing the gap between it and the scraper, causing the material to pile up and not be able to be flattened into a layer, thus further improving the screening accuracy of the color sorter.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 This utility model provides a technical solution: Example

[0030] A color sorter anti-jumping device includes a workbench 1. Several support legs 2 are fixedly installed under the workbench 1 to raise the entire device and facilitate the screening and separation of materials by the color sorter. A color sorter housing 3 is fixedly installed on the side of the workbench 1. A control panel 4 and an air compressor 5 are fixedly installed on the outer wall of the color sorter housing 3. A partition 6 is fixedly installed inside the color sorter housing 3. LED lights 7 and several optical lenses 8 are fixedly installed on both sides of the partition 6 inside the color sorter housing 3. A spray valve 9 is fixedly inserted below the optical lens 8. The spray valve 9 is connected to the air compressor 5 through a connecting pipe 10. An inclined plate 11 is fixedly installed at the bottom of the color sorter housing 3.

[0031] LED light 7, optical lens 8, and spray valve 9 are all electrically connected to control panel 4. Control panel 4 can control the on / off state of LED light 7 and optical lens 8. In addition, through the built-in CPU and program, it can work with optical lens 8 to automatically control the on / off state of spray valve 9. When optical lens 8 detects defective material, it opens the spray valve 9 below to blow the defective material onto inclined plate 11, separating the defective material from the good material. The working principle of the color sorter here is existing technology and can be replaced by existing technology, so it will not be described in detail.

[0032] The workbench 1 is equipped with a filtration mechanism capable of separating materials by size. The filtration mechanism includes a filter box 12 fixedly mounted on the workbench 1, with a feed hopper 13 fixedly connected to the filter box 12. Several sliding rods 14 are fixedly mounted inside the filter box 12, with filter screens 15 and receiving plates 16 slidably mounted on each rod 14. Both the filter screens 15 and the receiving plates 16 have a special sloping structure, with their lowest points at the discharge port 22. The filter screens 15 are positioned above the receiving plates 16. Springs 36 are fitted under each sliding rod 14 below the filter screens 15 and the receiving plates 16. A limit plate 37 is fixedly mounted below each sliding rod 14 and provides support for the filter screens 15 and 16. The filter screen 15 and the receiving plate 16 provide a slight buffer to prevent heavy impact on the limiting plate 37 and damage. Inside the filter box 12, a rotating shaft 17 is rotatably installed below the filter screen 15 and the receiving plate 16. A cam 18 is fixedly installed on the rotating shaft 17. Both rotating shafts 17 are fixedly installed with pulleys 19 on the outside of the filter box 12. A belt 20 is fitted on the two pulleys 19. One of the rotating shafts 17 is also fixedly installed with pulley 21 on the outside of the filter box 12. The filter box 12 has two discharge ports 22. A chute 23 is fixedly installed at the discharge port 22. The filter screen 15 and the receiving plate 16 are both located above the chute 23.

[0033] When material enters the filter box 12 from the feed hopper 13, it first falls onto the filter screen 15. The motor 30, through the cooperation of the drive shaft 25, pulleys, and belts, causes the rotating shaft 17 and cam 18 under the filter screen 15 to rotate, making the filter screen 15 vibrate up and down, thus enabling the material to be filtered quickly. Then, it falls onto the receiving plate 16. At the same time, the rotating shaft 17 and cam 18 under the receiving plate 16 are also rotated synchronously by the cooperation of two pulleys 19 and belt 20, causing the receiving plate 16 to vibrate up and down as well. This allows large particles on the filter screen 15 and small particles on the receiving plate 16 to slide quickly out of the discharge port 22 and fall into the chute 23, and finally onto different conveyor belts 29, so that the material is classified according to size. Example

[0034] The workbench 1 is equipped with an anti-jump mechanism to prevent material from jumping after separation. The anti-jump mechanism includes three parallel baffles 24 fixedly mounted on the workbench 1. The three baffles 24 divide the workbench 1 into two areas, which handle large particles and small particles respectively. A drive shaft 25 and a driven shaft 26 are rotatably inserted on the three baffles 24. A drive roller 27 is fixedly mounted on the drive shaft 25 between the baffles 24. A driven roller 28 is fixedly mounted on the driven shaft 26 between the baffles 24. A conveyor belt 29 is fitted on the drive roller 27 and the driven roller 28. A motor 30 is fixedly mounted on one end of the drive shaft 25. The motor 30 is fixedly mounted on the baffle 24. A pulley 31 is fixedly mounted on the end of the drive shaft 25 away from the motor 30. A belt 32 is fitted on the pulley 31 and the pulley 21.

[0035] When the motor 30 starts, the drive shaft 25 simultaneously drives the drive rollers 27 in both areas to rotate. The drive rollers 27 then drive the conveyor belts 29 in both areas to move towards the color sorter. When the conveyor belts 29 move, they cause the driven rollers 28 and driven shaft 26 to rotate, so that the conveyor belts 29 can move in a cycle, thereby continuously transporting the materials in the two areas to the color sorter. At the same time, when the drive shaft 25 rotates, the pulley 31 also rotates, and then drives the pulley 21 to rotate through the belt 32, causing the shaft 17 on the pulley 21 to rotate. Example

[0036] The conveyor belt 29 is equipped with a smoothing component for leveling materials. The smoothing component includes several movable grooves 33 opened on the baffles 24. A threaded rod 34 is rotatably engaged in the movable grooves 33. By rotating the threaded rod 34, the scraper 35 can be moved up and down, thereby adjusting the distance between the scraper 35 and the conveyor belt 29. The scrapers 35 in the two areas can be adjusted separately. The scraper 35 in the area of ​​large particles is higher than the scraper 35 in the area of ​​small particles. The height can be adjusted to a suitable height according to the size of the material. Scrapers 35 that are threadedly engaged with the threaded rod 34 are movably engaged in the movable grooves 33 on two adjacent baffles 24. A support plate 38 is fixedly installed between two adjacent baffles 24. The support plate 38 is located below the conveyor belt 29 on the side closer to the scraper 35 and is in contact with the conveyor belt 29. The support plate 38 can support the conveyor belt 29 and the material on it, preventing the material from piling up due to the increased gap between the conveyor belt 29 and the scraper 35 caused by deformation.

[0037] Working principle: First, adjust the two scrapers 35 to a suitable height by rotating the threaded rod 34. Then, control the motor 30, LED light 7, optical lens 8 and air compressor 5 through the control panel 4. Then, pour the material into the feed hopper 13. After the motor 30 starts, the conveyor belt 29 moves towards the color sorter through the drive shaft 25 and drive roller 27. At the same time as the drive shaft 25 rotates, the pulley 31 on it also rotates. The belt 22 drives the pulley 21 to rotate, and the rotating shaft 17 fixedly connected to the pulley 21 also rotates. When the rotating shaft 17 rotates, the two rotating shafts 17 rotate synchronously through the cooperation of the two pulleys 19 and belt 20, so that the two cams 18 rotate together, thereby causing the filter screen 15 and the receiving plate 16 to vibrate up and down, filtering and separating the material, which finally slides onto different conveyor belts 29.

[0038] The conveyor belt 29 will move the material on it towards the color sorter. When passing through the scraper 35, the material on the conveyor belt 29 can be smoothed into a layer. Finally, it enters the color sorter and falls in a parabolic direction. With the cooperation of LED light 7 and optical lens 8, defective products and good products can be distinguished. When a defective product is identified, the corresponding spray valve 9 will open instantly and spray the defective product onto the inclined plate 11, thereby separating the good and defective products of the material.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
