Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice impurity detection technology, and in particular to a rice packaging line with impurity detection function. Background Technology
[0002] Rice packaging lines with impurity detection functions occupy a crucial position in the rice processing industry. With the continuous improvement of people's requirements for rice quality and the trend of large-scale and automated development in the rice processing industry, this production line has become a key piece of equipment to ensure rice quality and production efficiency. It integrates multiple functions such as paddy cleaning, impurity detection, and rice packaging. Through a series of mechanical equipment and advanced technologies, it can quickly and accurately remove impurities from rice and package it according to different specifications to meet the diverse needs of the market. However, in practical applications, in order to further improve the quality of rice and production efficiency, it is necessary to continuously optimize and improve each link in the production line.
[0003] In existing rice packaging lines with impurity detection capabilities, the color sorter, as the core equipment for impurity detection, typically employs optical detection technology. Its working principle utilizes the differences in optical properties such as color and reflectivity between rice and impurities. A high-speed camera and image processing system monitor and analyze the rice in real time. When an impurity is detected, the control system drives a corresponding jet device to blow the impurity out, thereby achieving impurity separation. In addition, other equipment in the production line, such as rice cleaning machines and packaging machines, also have their own unique mechanical structures and working principles. Rice cleaning machines remove large particles of impurities and dust from rice through methods such as vibrating screens and air separation; packaging machines quantitatively package qualified rice through processes such as weighing and sealing.
[0004] However, existing rice packaging lines with impurity detection functions have significant shortcomings in the color sorting stage. Because the optical properties of rice and impurities are sometimes similar, or the distribution of impurities in rice is complex, color sorters often cannot completely remove all impurities in a single color sorting process. This results in a certain amount of impurities remaining in the rice after color sorting, which not only affects the quality and market competitiveness of the rice, but also leads to quality problems in subsequent processing and sales. Therefore, a rice packaging line with impurity detection function is proposed to solve the above problems. Utility Model Content

[0035] 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.
[0036] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a rice sorting production line with impurity detection function, including a color sorter 1. The color sorter 1 has an inlet 3 inside, which is funnel-shaped and has a smooth inner wall to ensure that the rice flows smoothly into the color sorter 1 and avoids blockage. The color sorter 1 has a control screen 4 inside, and a finished product discharge pipe 5 is fixedly connected to the bottom of the control screen 4. A defective product discharge pipe 8 is connected to the bottom of the control screen 4. A finished product collection box 6 is set at the bottom of the finished product discharge pipe 5, and a defective product collection box 7 is set at the bottom of the defective product discharge pipe 8. A circulation component is set on the outer wall of the color sorter 1, and a stabilizing component is set at the bottom of the color sorter 1.
[0037] The circulation assembly includes a circulating fan 11 and a circulating pipe 2. The outer wall of the circulating fan 11 is fixedly connected to the outer wall of the color sorter 1. The circulating fan 11 is a high-performance centrifugal fan with an aluminum alloy shell, which is lightweight and has good heat dissipation. The outer wall of the circulating fan 11 is firmly fixed to the outer wall of the color sorter 1 with bolts to ensure operational stability. A fixing ring 10 is fixedly connected to the outer wall of the color sorter 1. The circulating pipe 2 is made of soft and wear-resistant rubber. Its outer wall is located inside the circulating fan 11 and passes through the fixing ring 10 for fixation. The outer wall of the circulating pipe 2 is located inside the circulating fan 11 and inside the fixing ring 10. One end of the circulating pipe 2 is located at the top of the inlet 3, and the other end of the circulating pipe 2 is slidably connected to the inside of the defective product outlet pipe 8.
[0038] Specifically, in the rice processing process, efficient and accurate testing and screening of rice is a key step in ensuring rice quality. Rice is fed into color sorter 1 through inlet 3. Color sorter 1, as the core equipment, can precisely screen rice based on the differences in optical properties between rice and impurities. Operators can also flexibly adjust mechanical parameters via control panel 4 to adapt to the screening needs of different rice varieties. After screening by color sorter 1, the rice is divided into finished product and substandard product. Finished product falls into finished product collection box 6 through finished product discharge pipe 5, while substandard product... The defective products fall into the defective product collection box 7 through the defective product discharge pipe 8, realizing the separation of finished products and defective products. In order to further improve the quality and purity of rice, the circulating fan 11 can be started during the screening process. The circulating fan 11 drives the circulating pipe 2 to suck out the defective products in the defective product discharge pipe 8 and transport them back to the top of the inlet 3 through the circulating pipe 2 for secondary screening. This circulating screening method can effectively remove residual impurities, enabling rice to reach a higher quality standard, while avoiding resource waste and improving the efficiency and benefits of the entire rice processing process.
[0039] Reference Figures 1-3 The stabilizing component includes a locking block 17, which is made of high-strength carbon steel and undergoes fine forging and heat treatment processes, resulting in high hardness and wear resistance. Its surface is polished, making it smooth and flat, effectively reducing friction when in contact with other components. The locking block 17 has a unique shape design, with one side being a slope and the other a flat surface. This special shape facilitates subsequent locking and sliding operations. The locking block 17 is located on the outer wall of the finished product collection box 6. A placement rack 13 is fixedly connected to the bottom of the color sorter 1, and a placement plate 9 is fixedly connected to the bottom of the placement rack 13. The finished product collection box 6 is located inside the placement plate 9, and a ramp 12 is provided inside the finished product collection box 6. A fixing block 22 is fixedly connected to the outer wall of the finished product collection box 6, and a connecting column 20 is slidably connected inside the fixing block 22. The outer wall of the connecting column 20... A limiting ring 21 is fixedly connected. The limiting ring 21 is made of rubber and has a certain elasticity, which can play a role in buffering and limiting. The other end of the connecting column 20 is fixedly connected to the outer wall of the locking block 17. A second conical block 18 is provided on the outer wall of the locking block 17. A second spring 19 is sleeved on the outer wall of the connecting column 20. One end of the second spring 19 is fixedly connected to the outer wall of the locking block 17, and the other end of the second spring 19 is fixedly connected to the outer wall of the fixing block 22. A sliding column 15 is fixedly connected to the outer wall of the second conical block 18. The outer wall of the sliding column 15 is fixedly connected to the inside of the placement rack 13. A first conical block 16 is slidably connected to the outer wall of the sliding column 15. The second conical block 18 is in contact with the locking block 17. A first spring 14 is provided inside the placement rack 13. One end of the first spring 14 is fixedly connected to the inner wall of the placement rack 13, and the other end of the first spring 14 is provided on the outer wall of the finished product collection box 6.
[0040] Specifically, after rice screening, proper collection of the screened rice is a crucial step in the entire processing. When collecting the screened rice, the collection box can be placed inside the placement rack 13. During placement, because the contact surface of the locking block 17 is inclined, it will be pushed and moved by the conical block 18 when it comes into contact with it. As the locking block 17 moves, it will cause the connecting column 20 to slide inside the fixed block 22, while simultaneously compressing the spring 19. At the same time, the finished product collection box 6 will compress the spring 14 during placement. When the locking block 17 moves to the other side of the conical block 18, the spring 19 will rebound, causing the locking block 17 to slide onto the conical block 18. On the other side, since both the locking block 17 and the conical block 18 are flat, they can engage. Furthermore, the rebound of the spring 14 makes the engagement between the locking block 17 and the conical block 18 even more secure, effectively maintaining the stability of the collection box and preventing shaking during rice collection, thus ensuring smooth collection operations. When disassembly and maintenance of the finished product collection box 6 is required, the operator can continue to push the box. Because the locking block 17 has an inclined surface, it will slide to the other side of the conical block 16. Then, by pulling the box, the flat surface of the locking block 17 will move the conical block 16, bringing it into contact with the conical block 18. At this point, the conical block 16 is fixed and cannot move. Then, using the inclined surface of the conical block 16, the locking block 17 can slide out, allowing the finished product collection box 6 to be removed for easy maintenance. This design ensures the stability of the collection box during use and provides a convenient disassembly method, improving the maintainability of the equipment and overall production efficiency.
[0041] Working principle: When testing and screening rice, the rice is put in through the feed inlet 3 and screened by the color sorter 1. The machine can be adjusted through the control panel 4. Different types of rice are used. The screened rice is divided into finished product and substandard product. The finished product discharge pipe 5 and the substandard product discharge pipe 8 fall into the corresponding finished product collection box 6 and substandard product collection box 7 for separate placement. At the same time as screening, the circulating fan 11 can be started. The circulating fan 11 drives the circulating pipe 2 to suck out the substandard products in the substandard product discharge pipe 8 and transport them back to the top of the feed inlet 3 for secondary screening. This improves the quality and purity of the rice, enabling it to reach a higher quality standard and avoiding waste.
[0042] In addition, when collecting the sieved rice, the collection box can be placed inside the placement rack 13. Because the contact surface of the locking block 17 is inclined, the locking block 17 is moved by the second conical block 18. Then, the locking block 17 drives the connecting column 20 to slide inside the fixed block 22, compressing the second spring 19. The finished product collection box 6 compresses the first spring 14. When it reaches the other side of the second conical block 18, the second spring 19 rebounds, causing the locking block 17 to slide to the other side of the second conical block 18. Since both surfaces are flat, they engage. The first spring 14 then rebounds. The spring mechanism makes the locking block 17 and the second conical block 18 more securely engaged, thus maintaining the stability of the collection box and preventing shaking during collection. When disassembling and maintaining the finished product collection box 6, the locking block 17 can be pushed further through the inclined surface of the locking block 17, causing the locking block 17 to slide to the other side of the first conical block 16. Then, the finished product collection box 6 can be pulled, and the first conical block 16 can be moved through the plane of the locking block 17, so that it comes into contact with the second conical block 18, making the first conical block 16 fixed and unable to move. Then, the locking block 17 can be slid out through the inclined surface of the first conical block 16, allowing the finished product collection box 6 to be removed for maintenance.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
