Description
Technical Field
[0001] This utility model relates to the field of color sorters, and in particular to a stainless steel color sorter track structure that is easy to clean. Background Technology
[0002] A color sorter is a non-destructive sorting device based on the differences in the optical properties of materials. It automatically sorts particles of different colors using photoelectric detection technology and is widely used in industries such as food, chemicals, and mining to achieve quality inspection and grading of bulk materials and industrial products. The main core functional modules of a color sorter include a vibrator, conveyor belt, solenoid valve, display screen, air supply unit, and hardware modules such as a camera board, main light board, and light control board. The conveyor belt (tracked conveyor) can be selected in different ways depending on the material characteristics, such as tracked or free-fall conveying.
[0003] During operation, the conveyor belt of a color sorter is in constant contact with materials, making it prone to accumulating residual dust, debris, and other impurities, which can easily form scale on the belt surface. To improve detection accuracy, it is necessary to keep the conveyor belt surface clean and prevent contaminants from interfering with the identification of the materials being sorted. Therefore, regular cleaning and maintenance of the conveyor belt is a key aspect of ensuring the stable operation of the color sorter.
[0004] One of the commonly used cleaning methods is to physically scrape the surface of the conveyor belt with a brush. This method relies solely on the mechanical contact between the brush bristles and the conveyor belt surface to remove contaminants, resulting in insufficient cleaning power. The dust removed and the dust on the brush are also easily dispersed. At the same time, the brush itself is prone to accumulating dust, which may become a source of pollution, causing cross-contamination and affecting the cleaning effect of the conveyor belt. Utility Model Content
[0005] This invention provides an easy-to-clean stainless steel color sorter track structure, which solves the problems of insufficient cleaning power, easy dust dispersion, and easy impact on cleaning effect of existing easy-to-clean stainless steel color sorter track structures, where brushes are used to scrape the conveyor belt.
[0006] An easy-to-clean stainless steel color sorter track structure includes a frame located on one side of the color sorter and a track conveyor belt mounted on the frame. The bottom of the track conveyor belt is provided with a plurality of dust collection baskets arranged in a staggered and spaced manner. Each dust collection basket is rotatably connected to a brush roller that contacts the surface of the track conveyor belt. One of the dust collection baskets located at the edge is provided with a drive component for driving the brush roller to rotate synchronously.
[0007] Multiple dust collection baskets are fixedly connected to each other. One side of another dust collection basket located at the edge is provided with a control component for driving the dust collection basket and the brush roller inside the dust collection basket to reciprocate in a direction perpendicular to the running direction of the conveyor belt. An impact rod is fixed on the inner wall of the dust collection basket and below the brush roller. The impact rod is located within the area of the brush roller bristle rotation zone.
[0008] Preferably, each of the dust collection baskets is provided with a dust collection component at the bottom, and a dust collection system is provided on one side of the frame. Each of the dust collection baskets is connected to the dust collection system through a corresponding dust collection component.
[0009] Preferably, each plurality of brush rollers located on the same horizontal line are fixedly connected by a coupling, one end of which extends to a drive assembly, which can drive two couplings to rotate synchronously.
[0010] Preferably, the drive assembly includes a first motor fixed to the dust collection basket and two pulleys. The two pulleys are fixed to the corresponding ends of a coupling. The two pulleys are connected by a belt. One of the couplings is fixedly connected to the output shaft of the first motor.
[0011] Preferably, two fixing plates are fixedly provided at the bottom of the frame and on the side near the dust collection basket. The control component includes a rotating shaft rotatably connected between the fixing plates, a crank fixedly mounted on the rotating shaft, a connecting rod rotatably connected to the eccentric part of the crank, and a second motor fixedly mounted on one of the fixing plates. One end of the rotating shaft is fixedly connected to the output shaft of the second motor, and one end of the connecting rod is rotatably connected to the dust collection basket.
[0012] Preferably, guide rails are fixedly provided on both the fixed plate and one side of the dust collection basket, and slide rails that are slidably connected to the corresponding guide rails are fixedly provided on the dust collection basket.
[0013] Preferably, the dust collection assembly includes a dust collection hood fixed to the bottom of the dust collection basket and a connecting hose fixed to the bottom of the dust collection hood, the connecting hose being connected to the dust collection system.
[0014] Preferably, the vacuuming system includes a vacuum cleaner located on one side of the frame and a dust collection pipe fixed at the air inlet of the vacuum cleaner, with the bottom end of each connecting hose connected to the dust collection pipe.
[0015] Preferably, each of the brush rollers is provided with a plurality of impact rods below it, and each of the impact rods has a protrusion structure of different heights on its surface.
[0016] Preferably, a gap is provided between the top of each dust collection basket and the surface of the conveyor belt.
[0017] This utility model provides an easy-to-clean stainless steel color sorter track structure, which has the following beneficial effects:
[0018] 1. When cleaning dust from the surface of the conveyor belt using a rotating brush roller, a dust collection basket is installed outside the brush roller, and an impact bar is installed inside the dust collection basket. The dust and debris brushed off fall downwards under the force of gravity and the throwing action of the brush roller. As the brush roller rotates at high speed, its bristles periodically sweep across and impact the impact bar. This impact generates vibration and shock, effectively shaking off dust particles from the bristles, allowing the bristles to self-clean and maintaining the brush roller's continuous and effective cleaning ability. The shaken-off dust eventually falls into the dust collection hood, which is connected to a dust collection pipe via a connecting hose. The dust collection pipe is connected to the inlet of the vacuum cleaner, creating a continuous negative pressure to promptly suck out the dust collected in the basket, effectively preventing dust escape and achieving efficient and automated cleaning of the stainless steel color sorter conveyor belt.
[0019] 2. The dust collection baskets are staggered and spaced apart, arranged in a left-right configuration, with overlapping areas between adjacent brush rollers to ensure complete coverage of the conveyor belt surface. Driven by the control component, the dust collection baskets move synchronously back and forth beneath the conveyor belt. Simultaneously, the brush roller bristles maintain contact with the lower surface of the conveyor belt and rotate continuously under the drive component. While the brush bristles rotate and clean the conveyor belt surface, the movement of the dust collection baskets ensures that the cleaning action covers the entire surface of the conveyor belt, achieving comprehensive cleaning and improving the cleaning effect.

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0027] like Figures 1 to 4 As shown in the figure, an easy-to-clean stainless steel color sorter track structure provided by this utility model embodiment includes a frame 1 located on one side of the color sorter and a track conveyor belt 2 installed on the frame 1. The bottom of the track conveyor belt 2 is provided with a plurality of dust collection baskets 3 arranged in a staggered manner and at intervals. Each dust collection basket 3 is rotatably connected to a brush roller 4 that contacts the surface of the track conveyor belt 2. One of the dust collection baskets 3 located at the edge is provided with a drive component for driving the brush roller 4 to rotate synchronously. The plurality of dust collection baskets 3 are fixedly connected to each other. Another dust collection basket 3 located at the edge is provided with a control component on one side for driving the dust collection basket 3 and the brush roller 4 inside the dust collection basket 3 to reciprocate in a direction perpendicular to the running direction of the track conveyor belt 2. An impact rod 19 is fixedly provided on the inner wall of the dust collection basket 3 and below the brush roller 4. The impact rod 19 is located within the range of the brush roller 4's brush bristle rotation area.
[0028] When the tracked conveyor belt 2 transports dry powdery, granular, or flaky materials, mechanical adhesion or electrostatic adsorption often occurs between the material and the conveyor belt surface, potentially attracting dust, debris, and other impurities. The dust collection basket 3, driven by the control component, moves synchronously back and forth beneath the tracked conveyor belt 2. During this reciprocating movement, the bristles of the brush roller 4 remain in contact with the lower surface of the tracked conveyor belt 2 and rotate continuously under the drive of the drive component. While the brush bristles rotate and clean the track surface, the movement of the dust collection basket 3 ensures that the cleaning action covers the entire surface of the track, achieving comprehensive cleaning of the tracked conveyor belt 2. The dust and debris brushed off fall downwards under the influence of gravity and the throwing action of the brush roller 4. Furthermore, as the brush roller 4 rotates at high speed, its bristles periodically sweep across and impact the impact rod 19. This impact generates vibration and shock, effectively shaking off dust particles from the bristles, allowing them to self-clean and maintaining the continuous and effective cleaning capability of the brush roller 4. The dislodged dust eventually falls to the bottom of the dust collection basket 3 for easy collection and cleaning. Through the lateral movement and rotation of the brush roller 4 and the cleaning action of the brush bristles by the impact rod 19, efficient and automated cleaning of the stainless steel color sorter track is achieved.
[0029] In some specific implementation plans, such as Figure 2 and Figure 3 As shown, guide rails 8 are fixedly mounted on the fixed plate 10 and on one side of the dust collection basket 3, and slide rails 9 are fixedly mounted on the dust collection basket 3 and slidably connected to the corresponding guide rails 8. The dust collection basket 3 is mounted on the fixed plate 10 through the cooperation of the slide rails 9 and the guide rails 8, which supports the dust collection basket 3 and its internal components. At the same time, the cooperation of the slide rails 9 and the guide rails 8 ensures the free and smooth movement of the dust collection basket 3 and its internal brush rollers 4. To ensure the stability of the dust collection basket 3, at least four slide rails 9 are provided on each dust collection basket 3, arranged in an equidistant and symmetrical structure on the outside of the dust collection basket 3.
[0030] In some specific implementation plans, such as Figure 1 , Figure 2 and Figure 3 As shown, each dust collection basket 3 is equipped with a dust collection component at its bottom, and a dust collection system is located on one side of the frame 1. Each dust collection basket 3 is connected to the dust collection system via a corresponding dust collection component. The dust collection component includes a dust collection cover 18 fixed to the bottom of the dust collection basket 3 and a connecting hose 16 fixed to the bottom of the dust collection cover 18. The connecting hose 16 is connected to the dust collection system. The dust collection system includes a vacuum cleaner 17 located on one side of the frame 1 and a dust collection pipe 15 fixed at the air inlet of the vacuum cleaner 17. The bottom end of each connecting hose 16 is connected to the dust collection pipe 15.
[0031] During the cleaning process, the dust shaken off by the brush bristles and the impact bar 19, as well as the dust cleaned by the brush bristles and the surface of the conveyor belt, falls into the dust collection hood 18. The dust collection hood 18 is connected to the dust collection pipe 15 through the connecting hose 16. The dust collection pipe 15 is connected to the inlet of the vacuum cleaner 17, forming a continuous negative pressure, which promptly sucks out the dust collected in the basket, effectively preventing the dust from escaping.
[0032] In some specific implementation plans, such as Figure 2 and Figure 3 As shown, each of the multiple brush rollers 4 located on the same horizontal line is fixedly connected to a coupling 5, and the drive assembly can drive two couplings 5 to rotate synchronously. The drive assembly includes a first motor 6 fixed on the dust collection basket 3 and two pulleys 7. The two pulleys 7 are fixed to the ends of the corresponding couplings 5 and are connected by a belt. One of the couplings 5 is fixedly connected to the output shaft of the first motor 6.
[0033] The output shaft of the first motor 6 drives the brush roller 4 to rotate through the coupling 5. Under the action of the pulley 7 installed at the end of the coupling 5 and the belt drive, all the brush rollers 4 are driven to rotate synchronously to brush and clean the surface of the track conveyor belt 2.
[0034] In some specific implementation plans, such as Figure 2 and Figure 3As shown, two fixed plates 10 are fixed at the bottom of the frame 1 and on the side near the dust collection basket 3. The control component includes a rotating shaft 12 rotatably connected between the fixed plates 10, a crank 13 fixed on the rotating shaft 12, a connecting rod 14 rotatably connected to the eccentric part of the crank 13, and a second motor 11 fixed on one of the fixed plates 10. One end of the rotating shaft 12 is fixedly connected to the output shaft of the second motor 11, and one end of the connecting rod 14 is rotatably connected to the dust collection basket 3.
[0035] The second motor 11 drives the rotating shaft 12 to rotate, which in turn drives the crank 13 and connecting rod 14 to move, causing the entire dust collection basket 3 to reciprocate on the guide rail 8, and the brush roller 4 to reciprocate on the surface of the conveyor belt, thus enhancing the cleaning effect.
[0036] In some specific implementation plans, such as Figure 4 As shown, each brush roller 4 has multiple impact bars 19 below it, and each impact bar 19 has a raised structure of different heights on its surface. The raised structure is a protrusion of varying length extending outward from the edge of the bar base. The bristles of the brush roller 4 strike the protrusions in sequence. Due to the different lengths of the protrusions, different impact forces and vibration frequencies are generated, which helps to better shake off the dust on the bristles. The impact bars 19 are preferably made of wear-resistant and somewhat elastic materials (such as polyurethane, nylon, or rubber) to reduce noise and improve durability.
[0037] In some specific implementation plans, such as Figure 2 and Figure 3 As shown, each dust collection basket 3 has a gap between its top and the surface of the conveyor belt 2. The dust collection basket 3 is kept basically close to the surface of the conveyor belt 2, without contacting it. The minimum gap also reduces the escape of cleaned dust. The staggered and spaced structure of the dust collection baskets 3, arranged in a left-right configuration, with overlapping areas between adjacent brush rollers 4, ensures complete coverage of the conveyor belt surface.
[0038] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:
[0039] When the conveyor belt 2 transports materials to be sorted, its surface passes sequentially over the dust collection basket 3 area. The output shaft of the first motor 6 drives the brush rollers 4 to rotate via the coupling 5. Through the pulley 7 installed at the end of the coupling 5 and the belt drive, all the brush rollers 4 are driven to rotate synchronously, cleaning the surface of the conveyor belt 2. At the same time, the second motor 11 drives the rotating shaft 12 to rotate, which in turn drives the crank 13 and connecting rod 14 to move, causing the entire dust collection basket 3 group to reciprocate on the guide rail 8. The brush rollers 4 reciprocate on the surface of the conveyor belt, enhancing the cleaning effect.
[0040] The dust and debris brushed off fall downwards under the force of gravity and the throwing action of the brush roller 4. As the brush roller 4 rotates at high speed, its bristles periodically sweep across and impact the impact bar 19. This impact generates vibration and shock, effectively shaking off dust particles from the bristles, allowing the bristles to self-clean and thus maintaining the continuous and effective cleaning ability of the brush roller 4. During the cleaning process, the dust shaken off by the brush bristles and impact bar 19, as well as the dust cleaned by the brush bristles and conveyor belt surface, falls into the dust collection hood 18. The dust collection hood 18 is connected to the dust collection pipe 15 via the connecting hose 16. The dust collection pipe 15 is connected to the inlet of the vacuum cleaner 17, forming a continuous negative pressure to promptly suck out the dust collected in the basket, effectively preventing dust from escaping.
[0041] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
