Description

Technical Field

[0001] This utility model belongs to the technical field of color sorter accessories, and in particular relates to an adjustable background plate for a color sorter. Background Technology

[0002] A color sorter is a precision device that separates materials based on differences in their optical properties. It is widely used in various fields such as grains, tea, plastics, and ores. Its working principle involves illuminating the material with a light source, capturing the image information of the material using a camera, and comparing it with the color of a preset background plate to identify and remove discolored particles or impurities. Therefore, the background plate serves as a crucial reference in the color sorting process, and its color and condition directly affect the accuracy and effectiveness of the sorting.

[0003] In practical applications, when faced with different types and colors of materials to be sorted, such as different varieties of rice, different grades of tea, and different types of plastic granules, it is often necessary to use background boards of different colors or hues to obtain the best contrast and sorting effect. Traditional color sorters usually use bolts to fix the background board. When it is necessary to replace the background board to adapt to different materials, the operator needs tools to remove the original background board and then install the new background board. This process is time-consuming, labor-intensive, and inefficient.

[0004] To address this issue, we provide an adjustable background plate for a color sorter. Utility Model Content

[0034] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0035] Please see Figures 1-6 The present invention provides the following technical solution:

[0036] An adjustable background plate for a color sorter includes:

[0037] Mounting plate 1;

[0038] Mounting slot 2 is located at the lower end of mounting plate 1;

[0039] The self-locking motor 3 is fixedly connected to the mounting slot 2 by bolts;

[0040] Rotating rod 4 is fixedly connected to the output shaft of self-locking motor 3 and rotatably connected to mounting plate 1;

[0041] Rotating frame 5 is fixedly connected to the circumferential surface of rotating rod 4;

[0042] Multiple slots 6 are respectively opened on the surface of the rotating frame 5 and pass through the upper end of the rotating frame 5;

[0043] Multiple first springs 17, with each pair of first springs 17 fixedly connected to the lower inner wall of one of the slots 6;

[0044] Multiple placement plates 18, each placement plate 18 being fixedly connected to the upper end of every two first springs 17;

[0045] The locking mechanism is provided in multiple ways. Each locking mechanism is set at the upper end of the rotating frame 5 to lock the positions of the background boards of various colors in the multiple placement plates 18, so as to facilitate quick disassembly and installation by personnel.

[0046] In a specific embodiment of this utility model, the mounting plate 1 serves as the basic frame of the entire device, providing a stable support structure. The mounting slot 2 is used to fix the self-locking motor 3, ensuring its stable operation. When the operator fixes the mounting plate 1 onto the color sorter, different colored background boards are selected according to different color sorting objects. Then, the background board is inserted into the slot 6, at which point it is placed on the upper end of the placement plate 18. The operator then locks the position of the background board using the locking mechanism. At this time, the first spring 17 is in a compressed state, and the elastic force of the first spring 17 drives the background board to press against the baffle 10, thereby locking the background board. When the color of the background board needs to be adjusted, the operator starts the self-locking motor 3, which drives the rotation... Rotating the lever 4 causes the rotating frame 5 fixed on it to rotate as well. By selecting the correct angle, the background board of the desired color can be rotated to the working position. After rotating to the appropriate working position, the self-locking motor 3 locks the rotating frame 5 on the lever 4 through its self-locking function to prevent it from rotating excessively. When the background board needs to be replaced, the operator only needs to release the locking mechanism from the locking state of the placement plate 18. In this way, due to the action of the first spring 17, the placement plate 18 will automatically pop out part of itself, allowing the operator to easily take it out or reinsert it. The locking mechanism is then used to lock the new background board again, which improves the speed and efficiency of background board replacement and also reduces the complexity of manual operation.

[0047] Please refer to the details. Figures 1-6 Each locking mechanism includes a fixed block 7, a rotating hole 8, a rotating rod 9, a baffle 10, a sliding groove 11, a second spring 12, a locking block 13, a connecting block 14, a locking groove 15, and a push rod 16. Each locking mechanism has two second springs 12. The fixed block 7 is fixedly connected to the upper end of the rotating frame 5. The rotating hole 8 is opened on one side of the fixed block 7 and passes through the fixed block 7. The rotating rod 9 is rotatably connected to the rotating hole 8. The baffle 10 is fixedly connected to the circumferential surface of the rotating rod 9. The sliding groove 11 is opened on one side of the baffle 10. One end of each of the two second springs 12 is fixedly connected to one side of the sliding groove 11. The locking block 13 is fixedly connected to the other end of the two second springs 12. The connecting block 14 is fixedly connected to one side of the rotating frame 5. The locking groove 15 is opened on one side of the connecting block 14. The locking groove 15 and the locking block 13 are matched. The push rod 16 is fixedly connected to the upper end of the locking block 13.

[0048] In this embodiment: when it is necessary to replace the background board placed on the placement plate 18, the operator pushes the push rod 16 forward. The push rod 16 drives the locking block 13 fixed to it to move within the slide groove 11, thereby compressing the two second springs 12. In this way, the locking block 13 disengages from the locking groove 15 of the connecting block 14, releasing the locking state of the slot 6. At this time, the two compressed first springs 17 release their elasticity, and the placement plate 18 will automatically pop out part of its length. The operator can then quickly remove the background board and insert the new background board into the slot. In step 6, pushing the push rod 16 causes the second spring 12 to retract the locking block 13 into the slide groove 11. At the same time, rotating the baffle 10 causes the rotating rod 9 to rotate in the rotating hole 8 on the fixed block 7. When the baffle 10 is rotated to the same horizontal plane as the connecting block 14, the push rod 16 is released. The elastic force of the second spring 12 automatically pushes the locking block 13 into the locking groove 15, thereby locking the background plate and preventing it from popping up. This ensures the stability of the background plate and realizes a simple and quick replacement process for the background plate.

[0049] Please refer to the details. Figures 1-6 Each rotating rod 9 has a limiting block 19 fixedly connected to both ends, and every two limiting blocks 19 are respectively attached to the two sides of each baffle 10.

[0050] In this embodiment: when the operator pushes the push rod 16 to make the rotating rod 9 rotate around the rotating hole 8, the limiting blocks 19 fixed at both ends of the rotating rod 9 will rotate accordingly. In this way, the limiting blocks 19 can fit against both ends of the baffle 10, restricting the axial movement of the rotating rod 9 during the rotation process.

[0051] Please refer to the details. Figures 1-6 The upper end of the mounting plate 1 is provided with a guide groove 20, and the lower end of the rotating frame 5 is fixedly connected with a guide block 21, which is rotatably connected in the guide groove 20.

[0052] In this embodiment: when the self-locking motor 3 drives the rotating rod 4 to rotate the rotating frame 5, the guide block 21 fixed at the lower end of the rotating frame 5 will rotate in the guide groove 20 opened at the upper end of the mounting plate 1. The cooperation between the guide block 21 and the guide groove 20 provides precise guidance and support for the rotation of the rotating frame 5. When the rotating frame 5 is subjected to uneven force or has slight manufacturing tolerances during rotation, the sliding of the guide block 21 in the guide groove 20 can effectively constrain its movement trajectory and prevent it from radially deviating or shaking.

[0053] Please refer to the details. Figures 1-6 A sealing ring 22 is fixedly connected to the circumferential surface of the rotating rod 4, and the sealing ring 22 is attached to the upper end of the mounting plate 1.

[0054] In this embodiment: when the rotating rod 4 rotates inside the mounting plate 1, the sealing ring 22 fixed on its circumferential surface will rotate together with the rotating rod 4 and continuously adhere to the upper end surface of the mounting plate 1. When there is dust, water vapor or other pollutants in the working environment of the color sorter, the sealing ring 22 can effectively prevent these impurities from entering the mounting groove 2 area where the self-locking motor 3 is located from the upper end of the mounting plate 1, thereby extending the service life of the equipment and reducing maintenance needs.

[0055] Please refer to the details. Figures 1-6 The upper end of the mounting plate 1 is provided with four mounting holes 23, which are distributed at the four corners of the mounting plate 1.

[0056] In this embodiment: when the entire adjustable background panel assembly needs to be installed onto the frame of the color sorter, the operator utilizes the four mounting holes 23 located at the four corners of the upper end of the mounting plate 1. Bolts or other fasteners can then be passed through these four mounting holes 23 to securely fix the mounting plate 1 to the predetermined position on the frame. The four mounting holes 23, distributed at the four corners of the mounting plate 1, provide the most balanced and stable support. Thus, when the equipment vibrates during operation, the mounting plate 1 and all its components remain stable and will not loosen or shift.

[0057] Please refer to the details. Figures 1-6 The rotating frame 5 is hexagonal in shape. When the first spring 17 is in a compressed state, the upper end of the background plate on the placement plate 18 is attached to the lower end of the baffle 10.

[0058] In this embodiment: Since the rotating frame 5 is hexagonal, each of its six sides is provided with a slot 6 and a corresponding placement plate 18, so it can accommodate six different colored background plates. When it is necessary to switch the background plate, the self-locking motor 3 drives the rotating frame 5 to rotate 60 degrees, so that the next placement plate 18 can be rotated to the working position. When the first spring 17 is in a compressed state, that is, when the background plate is pressed into the slot 6 for replacement, its range of motion is limited by the lower end face of the baffle 10, ensuring that the height of each background plate in the working position is consistent and stable. When different colored background plates are switched to the working position in sequence, the distance between them and the optical system of the color sorter can be precisely consistent, thereby ensuring the color sorting accuracy.

[0059] The working principle of this utility model is as follows: The mounting plate 1 is fixed to the designated position of the color sorter through the mounting holes 23 at the four corners. The self-locking motor 3 is connected to the drive system of the color sorter. A background plate of a suitable color is selected according to actual needs, and the background plate is inserted into the slot 6. At this time, the background plate is placed on the placement plate 18 supported by the first spring 17. Pushing the push rod 16 causes the second spring 12 to drive the locking block 13 back into the slide groove 11. Simultaneously, the baffle 10 is rotated. When the baffle 10 is rotated, the rotating rod 9 rotates within the rotating hole 8 on the fixing block 7. When the baffle 10 is rotated to the same horizontal plane as the connecting block 14, the push rod 16 is released. The elastic force of the second spring 12 automatically pushes the locking block 13 into the slot 15, thereby locking the background plate and preventing it from popping upwards. When the background plate needs to be replaced... Pushing the push rod 16 forward causes the locking block 13 to compress the second spring 12 and exit from the slot 15, releasing the lock on the background board. The compressed first spring 17 will automatically pop out part of the placement plate 18, making it easy to remove the old background board or insert a new background board. After inserting the new background board, operate the push rod 16 again to restore the locked state. When the background board needs to be adjusted to the working position during operation, the self-locking motor 3 is started, driving the rotating rod 4 and the rotating frame 5 fixed thereto to rotate. Since the rotating frame 5 is hexagonal, it rotates 60 degrees each time, which can accurately bring the required background board to the working position. When it is rotated to the appropriate working position, the self-locking motor 3 locks the rotating frame 5 on the rotating rod 4 through its own self-locking function to prevent it from rotating excessively, thereby completing the adjustment of the background board.

[0060] It should be noted that the installation and use of the self-locking motor 3 in this solution are existing technologies and will not be elaborated on in this article.
