Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to an intelligent sorting and monitoring device for food processing. Background Technology

[0002] Intelligent sorting and monitoring devices for food processing are typically integrated devices that combine sensing and detection, machine vision, intelligent algorithms, and automated sorting mechanisms. They are mainly used in the pre-processing, grading, and quality inspection stages of food processing. Their core function is to achieve automated quality screening, specification grading, and foreign object removal of food raw materials or semi-finished products. They are widely used in fruit and vegetable processing, grain processing, and other fields.

[0003] Traditional intelligent sorting and monitoring devices can only achieve single size classification or defect detection functions. The classification and detection processes are independent of each other, requiring an additional material transfer mechanism. At the same time, materials are prone to collision damage during the transfer process. Furthermore, some vision-based sorting devices do not consider the material's rotation requirements. The camera can only capture the surface of the material facing the lens on one side, making it difficult to achieve full-surface defect detection. There are blind spots in the detection, which cannot meet the requirements of high-precision sorting and have certain shortcomings. Utility Model Content

[0015] 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.

[0016] Example 1: Please refer to Figure 1 - Figure 6This utility model provides a technical solution: an intelligent sorting and monitoring device for food processing, including a screening box 1. Multiple screening cylinders 14 are evenly rotatably mounted in the middle of the screening box 1. Multiple openings 15 are evenly distributed in the middle of the multiple screening cylinders 14. Multiple guide holes 16 are evenly distributed on one side of the middle of one end of the screening box 1. An arc-shaped guide plate 17 is fixedly mounted at one end of each of the multiple guide holes 16. An arc-shaped cover plate 18 is fixedly mounted in the middle of the arc-shaped guide plate 17 located in the middle. A screening box 23 is fixedly connected to one end of the arc-shaped guide plate 17 located in the middle. A screening mechanism 24 is fixedly installed on one side of the middle of the screening box 23. Drive rollers 28 are rotatably installed at both ends of the middle of the screening box 23. A discharge port 32 is opened at both ends of one side of the middle of the screening box 23. A discharge spool plate 33 is fixedly connected to one end of each of the two discharge ports 32. A drive shaft 19 is fixedly installed at one end of each of the multiple screening cylinders 14. The multiple drive shafts 19 pass through one side of the screening box 1. Multiple drive shafts 19 are connected by a drive belt 22. A bracket 20 is fixedly installed on one side of the screening box 1. A motor 21 is fixedly installed in the middle of the bracket 20. The motor 21 is fixedly connected to one of the drive shafts 19. The openings 15 on the surfaces of multiple screening cylinders 14 gradually increase in size as the distance from the feed platform 11 increases. Two motors 29 are fixedly installed on both sides of the middle of one end of the screening box 23. The output ends of the two motors 29 are fixedly connected to one end of two drive rollers 28 respectively. The two drive rollers 28 rotate in opposite directions. The distance between the two drive rollers 28 is slightly smaller than the size of the opening 15 on the surface of the screening cylinder 14 located in the middle. Cylinders 30 are fixedly installed at both ends of the middle of one end of the screening box 23. The telescopic ends of the two cylinders 30 pass through the screening box 23 and are fixedly connected to push plates 31. One end of the two push plates 31 is slidably engaged with the middle of the corresponding feed tray 33. The industrial vision camera 27 is electrically connected to the cylinders 30.

[0017] In this embodiment, the size of the openings 15 on the surfaces of the multiple screening cylinders 14 gradually increases with the distance from the feeding platform 11. Combined with the rotation of the screening cylinders 14, this allows for precise grading of fruits of different sizes, such as oranges and apples, avoiding mixing of materials of different sizes and improving grading efficiency and accuracy. The screening cylinders 14 are synchronously driven by the drive shaft 19 and the drive belt 22, requiring only a single motor 21 to drive multiple screening cylinders 14, simplifying the drive structure and reducing equipment energy consumption and maintenance costs. The spacing between the two counter-rotating drive rollers 28 inside the screening box 23 is adapted to the size of the openings 15 of the central screening cylinder 14. The two drive rollers 28 rotate in opposite directions, allowing them to rotate while conveying fruits that have undergone initial size screening. Combined with the industrial vision camera 27 above, this enables more precise grading. The device comprehensively screens fruits with intact appearances and can perform secondary conveying of materials that have undergone preliminary grading by the screening cylinder 14. With the defect detection function of the industrial vision camera 27, it can accurately identify defects on the surface of the materials. The detection signal directly links the cylinder 30 to drive the push plate 31 to achieve automated and rapid removal of defective materials. It can effectively replace manual sorting, significantly reduce labor costs, and avoid the subjective errors of manual sorting, ensuring sorting consistency. The device can be adapted to the screening and sorting of different types and sizes of spherical or near-spherical fruits and vegetables by adjusting the size of the opening 15 of the screening cylinder 14, the distance between the transmission rollers, and the stroke of the cylinder 30 and the push plate 31. It does not require large-scale modification of the equipment structure, which can enhance the versatility and flexibility of the device and meet the production needs of diversified food processing.

[0018] Example 2: Figure 1 - Figure 3 As shown, a feeding platform 11 is fixedly installed at one end of the screening box 1. Multiple support legs 13 are evenly fixedly installed at the lower end of the feeding platform 11. A ramp 12 is provided in the middle of the feeding platform 11. The side of the ramp 12 with the lower height is connected to the screening box 1.

[0019] In this embodiment, a ramp 12 is provided in the middle of the feeding platform 11, and the lower side of the ramp 12 is connected to the screening box 1. The material can automatically slide into the screening cylinder 14 area inside the screening box 1 by its own gravity, which can simplify the equipment structure and realize continuous and smooth feeding of materials. The lower end of the feeding platform 11 is equipped with multiple support legs 13, which can effectively support the feeding platform 11 and effectively distribute the weight of the feeding platform 11 and the material, and prevent the feeding platform 11 from tilting or shaking due to excessive force on one side.

[0020] Example 3: As Figure 1 - Figure 6As shown, the screening mechanism 24 includes a top fixing plate 25, which is fixedly installed above one end of the screening box 23. An industrial vision camera 27 is fixedly installed in the middle of the top fixing plate 25. The camera end of the industrial vision camera 27 is located in the middle of the top fixing plate 25 and the screening box 23. Multiple light-shielding strips 26 are evenly arranged on both sides of the top fixing plate 25.

[0021] In this embodiment, the industrial vision camera 27 is suspended below the top fixed plate 25, with the camera end facing the material conveying path inside the screening box 23. This allows for full coverage imaging of the fruit surface without blind spots, ensuring accurate capture of minute defects such as mold, insect holes, and bruises. The industrial vision camera 27 adopts the working principle of patent number CN215964933U, which can effectively detect defects on the fruit surface. Multiple light-shielding strips 26 are set at both ends of the top fixed plate 25, which can effectively block stray light, backlight, or direct strong light in the workshop, avoiding problems such as image overexposure and blurring caused by light reflection, and providing stable and uniform detection lighting conditions for the industrial vision camera 27.

[0022] Working principle: like Figure 1 - Figure 6 As shown, the fruit material to be processed is first poured into the feeding platform 11. The inclined surface 12 in the middle of the feeding platform 11 provides guidance for the material. The material slides down the inclined surface 12 with its own gravity and finally enters the screening cylinder 14 area inside the screening box 1 smoothly. During this process, multiple support legs 13 evenly distributed at the lower end of the feeding platform 11 provide stable support, effectively distributing the weight of the feeding platform 11 and the material, preventing the feeding platform 11 from tilting or shaking, and ensuring a stable material conveying path.

[0023] When the material enters the screening box 1, motor 21 is started. Motor 21 drives one of the screening cylinders 14 to rotate via drive shaft 19, while the other screening cylinders 14 rotate synchronously with it via drive belt 22. Since the size of the openings 15 on the surfaces of the multiple screening cylinders 14 gradually increases with the distance from the feed platform 11, the material is graded according to its size during the rotation and conveying process of the screening cylinders 14: materials smaller than the opening 15 of the current screening cylinder 14 will fall through the opening 15 to the corresponding collection area; materials larger than the opening 15 will continue to be conveyed further along the screening cylinder 14 until they enter a matching screening cylinder 14 and are discharged through the corresponding guide hole 16 and arc-shaped guide plate 17. Driving multiple screening cylinders 14 synchronously with a single motor effectively reduces energy consumption and maintenance costs, and avoids mixing of materials of different sizes during screening.

[0024] After initial size classification, the material corresponding to the central screening cylinder 14, which conforms to the preset size specifications, will enter the arc-shaped guide plate 17 through the guide hole 16. Under the anti-leakage guidance of the arc-shaped cover plate 18, it will enter the screening box 23. The two motors 29 at both ends of the screening box 23 are started, and the two motors 29 drive the corresponding transmission rollers 28 to rotate in opposite directions. The distance between the two transmission rollers 28 is slightly smaller than the size of the opening 15 on the surface of the central screening cylinder 14, ensuring that the material can be stably clamped and conveyed by the two transmission rollers 28. Under the action of the reverse rotating transmission rollers 28, the material will rotate while being conveyed forward, so that all areas of the material surface can be fully displayed, providing the necessary conditions for the comprehensive inspection of the industrial vision camera 27. The industrial vision camera 27 in the screening mechanism 24 is suspended below the top fixed plate 25, and its camera end is directly facing the material conveying path of the transmission rollers 28, which can perform full-coverage imaging of the material during the rotation process without blind spots. During this process, multiple light-shielding strips 26 on both sides of the middle of the top fixing plate 25 can effectively block stray light, backlight, or direct strong light in the workshop, avoiding problems such as image overexposure and blurring caused by light reflection, and providing a stable and uniform detection lighting environment for the industrial vision camera 27. The industrial vision camera 27 adopts the working principle of patent number CN215964933U. Through image acquisition and analysis algorithms, it accurately identifies minute defects such as mold spots, insect holes, and dents on the surface of materials, and converts the detection results into electrical signals, which are transmitted to the control system in real time.

[0025] After receiving the detection signal from the industrial vision camera 27, the control system will make a real-time judgment on the signal. The material will continue to be conveyed forward with the transmission roller 28. If a defect is detected in the material, the control system will immediately send an action signal to the cylinder 30 at one end of the screening box 23. The telescopic end of the cylinder 30 drives the push plate 31 to move quickly. Since one end of the push plate 31 is slidably engaged in the middle of the feeding tray 33, the push plate 31 can accurately push the defective material into the corresponding feeding port 32 and feeding tray 33. The qualified material will also enter the corresponding feeding port 32 and feeding tray 33 through the push plate 31 under the push of the corresponding cylinder 30, thereby realizing the automated and rapid rejection of defective materials.
