Description

Technical Field

[0001] This utility model relates to the field of color sorting machine technology, and in particular to a solid waste color sorting machine. Background Technology

[0002] Color sorters are important devices used to separate products of different qualities or specifications based on their color differences. Existing color sorters generally use photoelectric detection systems to detect products and sort them into different collection devices based on the detection results. However, color sorters in related technologies have some drawbacks, such as low sorting accuracy and limited processing capacity. In addition, because the materials contain a lot of dust, after a period of use, dust will accumulate on the surface of the photoelectric sensors of the color sorter, affecting the detection performance of the device.

[0003] To address this, utility model patent CN220970020U discloses a sorting mechanism for a color sorter, including a ramp, a pre-inspection device, and a cleaning air pump. An air jet assembly is located on one side of the bottom of the ramp, and the pre-inspection device is located on one side of the top of the ramp. A photoelectric sensor 1 is equidistantly arranged at the bottom of the pre-inspection device. A final inspection device is located on one side of the bottom of the ramp, and a photoelectric sensor 2 is equidistantly arranged at the bottom of the final inspection device. A cleaning air pump is located on the front of both the pre-inspection and final inspection devices, and a nozzle is installed at the output end of the cleaning air pump. This utility model, through pre-inspection, final inspection, and material deceleration design, can effectively improve the accuracy of the device in detecting discolored materials, while also increasing its processing capacity. Furthermore, the cleaning air pump generates a high-pressure airflow, which is ejected by the nozzles to clean dust from the surfaces of photoelectric sensors 1 and 2, ensuring the accuracy of their detection and making the device easier to clean and maintain.

[0004] In practical use, we found that when the above-mentioned materials are discharged from the storage hopper, they are discharged directly and continuously in one go, which makes it easy for the materials to accumulate and slide down, resulting in high color sorting pressure and thus affecting the accuracy of the test. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a solid waste color sorter. In actual use, this color sorter utilizes a feeding mechanism to allow for intermittent discharge of materials in small quantities per discharge, thereby effectively reducing the color sorting pressure and improving the actual color sorting accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A solid waste color sorter includes a base, the upper end of which is fixedly connected to a folded connecting plate. The folded connecting plate consists of a horizontal part and an inclined part. A material box is installed on the upper end of the horizontal part of the folded connecting plate, and an air jet assembly is installed on the right side of the inclined part of the folded connecting plate. The inclined part of the connecting plate has multiple material drop troughs. A detection mechanism includes two detection components, each comprising two L-shaped connecting plates symmetrically fixedly connected to the front and rear sides of the inclined part of the folded connecting plate. An mounting strip is fixedly connected between the vertical parts of the two L-shaped connecting plates, and multiple photoelectric sensors are installed at the bottom of each mounting strip. A material drop mechanism is used to disperse the material into the material drop troughs.

[0008] Preferably, a fixing tube is fixedly connected to the opposite side of the vertical portion of each pair of mating L-shaped connecting plates, and a rotating disk is rotatably connected to each fixing tube via a bearing. A transparent glass cylinder is fixedly connected between each pair of mating rotating disks.

[0009] Preferably, the material feeding mechanism includes a columnar cavity formed in the inner wall of the right side of the material box, a drive motor is installed on the front side of the material box, and the output shaft of the drive motor passes through the columnar cavity and extends to the outside.

[0010] Preferably, the output shaft of the drive motor is fixedly connected to a rotating column on the outer side of the inner wall of the columnar cavity. A temporary storage groove is provided on one side of the rotating column, a discharge port is provided on the left side wall of the columnar cavity, and a communication port is provided on the right side wall of the columnar cavity.

[0011] Preferably, the output shaft end of the drive motor is connected to the rear left rotating disk via a first transmission component, and the two front rotating disks are connected via a second transmission component. The first transmission component includes two first synchronous pulleys respectively mounted on the output shaft end of the drive motor and the rear left rotating disk, and the two first synchronous pulleys are connected via a first synchronous transmission. The second transmission component includes two second synchronous pulleys respectively mounted on the front rotating disks, and the two second synchronous pulleys are connected via a second synchronous belt.

[0012] Preferably, the upper ends of each pair of mating L-shaped connecting plates are all fixedly connected to a U-shaped plate, the lower end of each U-shaped plate is fixedly connected to a spring, the lower ends of each pair of mating springs are all fixedly connected to a scraper, the upper end of each scraper is symmetrically fixedly connected to a guide rod, and the upper end of each guide rod passes through the horizontal part of the corresponding U-shaped plate and is slidably connected.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] Intermittent material discharge is achieved by driving the rotating column with a drive motor, resulting in a smaller amount of material discharged at one time. This effectively reduces the material handling pressure during color sorting, avoids inaccurate detection caused by material accumulation, and significantly improves the accuracy of color sorting. The first and second transmission components keep the transparent glass cylinder in a rotating state, which is less prone to dust adhesion compared to a stationary state, reducing the frequency of dust cleaning and lowering maintenance costs. At the same time, the scraper can be manually pressed to contact the transparent glass cylinder for dust cleaning when needed, ensuring its transparency and the detection accuracy of the photoelectric sensor. After the scraper is released, it no longer contacts the transparent glass cylinder under the action of the spring, reducing scraper wear and extending the service life of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A solid waste color sorter includes a base 1, with a folded connecting plate 2 fixedly connected to the upper end of the base 1. The folded connecting plate 2 is composed of a horizontal part and an inclined part. A material box 4 is installed on the upper end of the horizontal part of the folded connecting plate 2, and an air jet assembly 11 is installed on the right side of the inclined part of the folded connecting plate 2. Multiple material drop troughs 3 are opened on the inclined part of the folded connecting plate 2.

[0022] The system also includes a testing mechanism, which comprises two testing components. Each testing component includes two L-shaped connecting plates 9 symmetrically fixedly connected to the front and rear sides of the inclined portion of the folded connecting plate 2. An installation strip 19 is fixedly connected between the vertical portions of the two L-shaped connecting plates 9. Multiple photoelectric sensors are installed at the bottom of each installation strip 19. A processor, as shown in the figure, is also provided to cooperate with the photoelectric sensors and the jet assembly 11. The specific details can be found in the relevant part of the utility model patent with publication number CN220970020U. With the cooperation of multiple components, color sorting operations can be achieved.

[0023] Among them, each pair of L-shaped connecting plates 9 has a fixed tube 20 fixedly connected to the opposite side of the vertical part, and each fixed tube 20 is rotatably connected to a rotating disk 21 through a bearing, and a transparent glass tube 22 is fixedly connected between each pair of rotating disks 21.

[0024] The material also includes a material feeding mechanism, which is used to disperse the material into the material feeding trough 3. The material feeding mechanism includes a columnar cavity 12 opened in the inner wall of the right side of the material box 4. A drive motor 5 is installed on the front side of the material box 4. The output shaft of the drive motor 5 passes through the columnar cavity 12 and extends to the outside. A rotating column 13 is fixedly connected to the outer side of the inner wall of the columnar cavity 12. A temporary storage groove 14 is opened on one side of the rotating column 13. A discharge port 7 is opened on the left side wall of the columnar cavity 12. A communication port 6 is opened on the right side wall of the columnar cavity 12.

[0025] The output shaft of the drive motor 5 is connected to the rotating disk 21 on the left rear side via a first transmission component 8. The two rotating disks 21 on the front side are connected via a second transmission component 10. The first transmission component 8 includes two first synchronous pulleys respectively mounted on the output shaft of the drive motor 5 and the rotating disk 21 on the left rear side. The two first synchronous pulleys are connected via a first synchronous transmission. The second transmission component 10 includes two second synchronous pulleys respectively mounted on the rotating disks 21 on the front side. The two second synchronous pulleys are connected via a second synchronous belt. In actual use, the cooperation of the first transmission component 8 and the second transmission component 10 allows the transparent glass tube 22 to rotate. Compared to being fixed, it is less likely to attract dust.

[0026] In this configuration, the upper ends of each pair of mating L-shaped connecting plates 9 are all fixedly connected to a U-shaped plate 15, the lower ends of each U-shaped plate 15 are all fixedly connected to a spring 17, the lower ends of each pair of mating springs 17 are all fixedly connected to a scraper 16, the upper ends of each scraper 16 are symmetrically fixedly connected to a guide rod 18, and the upper ends of each guide rod 18 penetrate through the horizontal part of the corresponding U-shaped plate 15 and are slidably connected. This method can be used to achieve dust removal.

[0027] In this invention, the material is placed in the material box 4. At this time, the temporary storage slot 14 of the rotating column 13 is located in the columnar cavity 12 and is not connected to the discharge port 7 and the connecting port 6. When the color sorting operation needs to be started, the drive motor 5 is started, and the output shaft of the drive motor 5 starts to rotate. The output shaft of the drive motor 5 drives the rotating column 13 to rotate in the columnar cavity 12. When the temporary storage slot 14 of the rotating column 13 rotates to connect with the discharge port 7, the material in the material box 4 enters the temporary storage slot 14 through the discharge port 7. As the rotating column 13 continues to rotate, the temporary storage slot 14 connects with the connecting port 6. At this time, the material in the temporary storage slot 14 falls to the inclined part of the folded connecting plate 2 through the connecting port 6 and slides down along the inclined part. With the help of the photoelectric sensor and the jet assembly 11, color sorting can be achieved. This is the prior art. For details, please refer to the relevant part of the utility model patent with publication number CN220970020U. In this solution, the material is discharged intermittently with a small single discharge volume, thereby effectively reducing the color sorting pressure and improving the actual color sorting accuracy.

[0028] While the output shaft of the drive motor 5 rotates, it drives the rotating disk 21 on the rear left side to rotate via the first transmission component 8. Two first synchronous pulleys in the first transmission component 8 are respectively mounted on the end of the output shaft of the drive motor 5 and on the rotating disk 21 on the rear left side, and are connected by a first synchronous belt. Simultaneously, the two rotating disks 21 on the front sides are connected by a second transmission component 10, with two second synchronous pulleys in the second transmission component 10 respectively mounted on the front rotating disks 21, and connected by a second synchronous belt. Under the combined action of the first transmission component 8 and the second transmission component 10, all the transparent glass cylinders 22 are in a rotating state. This rotating state, relative to a stationary state, makes it less prone to dust adhesion, thus reducing the frequency of dust cleaning.

[0029] If cleaning is required, simply press the scraper 16 while the transparent glass tube 22 is rotating, keeping the scraper 16 in contact with the outer surface of the transparent glass tube 22. As the transparent glass tube 22 rotates, the scraper 16 will scrape off the dust and other impurities adhering to the outer surface of the transparent glass tube 22, ensuring the transparency of the transparent glass tube 22 and thus ensuring the detection accuracy of the photoelectric sensor. When cleaning is no longer required, release the scraper 16. Under the elastic action of the spring 17, the scraper 16 will no longer contact the transparent glass tube 22, reducing its wear.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
