Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and more specifically to a segmented conveyor with a stable structure. Background Technology

[0002] Segmented conveyors are commonly used in material loading and unloading, and are widely applied in material transfer processes across various industries such as mining, metallurgy, and building materials. However, long-term operation has revealed two critical technical challenges that urgently need to be addressed, severely impacting conveying efficiency and equipment lifespan: Firstly, during the high-speed rotation of the conveyor belt, the belt loses the compaction effect of the material above during the return phase, and the bottom naturally sags due to its own weight. Simultaneously, the combined effect of inertia easily generates significant vibration, leading to a substantial decrease in the stability of the entire conveying process. To address this issue, existing technologies generally employ the improvement of adding support rollers to the bottom of the conveyor belt. While this can suppress the belt's sag to some extent, the contact between the support rollers and the conveyor belt is only a line contact, with a relatively small contact area, resulting in very limited buffering and suppression of vibration. Therefore, it is difficult to fundamentally solve the problem of unstable conveying.

[0003] Secondly, the distribution of materials on the conveyor belt surface is often difficult to achieve completely uniformly, which directly causes an imbalance of forces on both sides of the conveyor belt. This is especially true when conveying crushed metals such as copper, iron, and aluminum, as well as mixtures of foam, plastic, and glass. These materials have a relatively large individual weight, and the uneven force distribution is further amplified, easily causing the conveyor belt to tilt and subsequently leading to belt misalignment. Misalignment not only accelerates the friction and wear between the conveyor belt edge and the frame, shortening the equipment's service life, but in severe cases, it can directly cause the conveyor belt to tear or break, leading to production interruptions. Currently, the industry often uses drum rollers and side baffles to improve the misalignment problem. However, these solutions only provide passive limiting and cannot actively apply adaptive reverse corrective thrust based on the real-time tilt of the conveyor belt. Therefore, the anti-misalignment effect is limited, and the limiting process also exacerbates localized wear between the rollers and the conveyor belt, increasing the equipment's maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide a segmented conveyor with a stable structure, which can improve the stability of the conveying process and actively prevent deviation according to the material distribution, thereby directly extending the service life of the equipment.

[0005] To achieve this objective, the present invention adopts the following technical solution: A segmented conveyor with a stable structure is provided, including a housing and a support frame. The top of the support frame is fixedly connected to the bottom of the housing. The housing has an L-shaped inclined structure. The conveyor also includes a first drive roller, a second drive roller, a conveyor belt, a stabilizing support assembly, and an active correction assembly. The first drive roller and the second drive roller are rotatably connected to the inner wall of the housing. The conveyor belt is wound around the periphery of the first drive roller and the second drive roller and rotates synchronously with them. The stabilizing support assembly includes a pair of support rollers and a support belt. The support rollers are rotatably connected to the inner wall of the housing. The support belt is wound around the periphery of the two support rollers and rotates synchronously with them. The top of the support belt is in contact with the bottom of the conveyor belt. The active correction assembly is installed in the housing and is used to actively correct the conveyor belt deviation.

[0006] Preferably, there are multiple stabilizing support components, which are distributed at equal intervals.

[0007] Preferably, the adjusting mechanism includes a screw and a fixed block, the fixed block is fixedly connected to the housing, the screw passes through the fixed block and is threadedly connected to it, and the screw is rotatably connected to the rotating seat.

[0008] Preferably, there are multiple active correction components located above the support roller and near the second drive roller. The active correction component includes a support plate, a pair of rotating frames, a pair of correction rollers, and a pair of triggering mechanisms. The support plate is fixedly connected to the inner wall of the housing, the rotating frames are rotatably connected to the bottom of the support plate, and the correction rollers are rotatably connected to the inner wall of the rotating frames. The correction rollers are located above the support rollers and are in contact with the bottom wall of the conveyor belt. The triggering mechanisms are installed on the support plate and are used to drive the correction rollers to rotate according to the tilt angle of the conveyor belt.

[0009] Preferably, the active correction assembly further includes a base plate, a rotating shaft, a pair of first toothed rings and a pair of second toothed rings. The center of the base plate is fixedly connected to the rotating shaft, the rotating shaft passes through the support plate and is rotatably connected to it, the first toothed rings are fixedly connected to both ends of the base plate, the second toothed rings are fixedly connected to the rotating frame, the second toothed rings mesh with the first toothed rings, and the two first toothed rings are centrally symmetrically distributed on both sides of the rotating shaft.

[0010] Preferably, the active correction component further includes a slide plate, a pair of tension springs, and a cam shaft. The slide plate is slidably connected to the top of the support plate. The top of the slide plate has an elongated groove for the rotating shaft to pass through. The rotating shaft has an L-shaped structure and a fisheye groove on its top. The cam shaft is fixedly connected to the top of the slide plate. The cam shaft passes through the fisheye groove and is slidably connected to it. The two tension springs are symmetrically arranged on both sides of the support plate. The opposite ends of the two tension springs are fixedly connected to the slide plate, and the opposite ends of the two tension springs are fixedly connected to the support plate.

[0011] Preferably, two triggering mechanisms are symmetrically arranged on both sides of the support plate. Each triggering mechanism includes a telescopic rod, a spring, a pressure plate, a roller, and a push block. The bottom of the telescopic rod is fixedly connected to the top of the support plate, and the telescopic end of the telescopic rod is fixedly connected to the bottom of the pressure plate. The spring is sleeved around the telescopic rod, and both ends of the spring are fixedly connected to the bottom of the pressure plate and the top of the support plate, respectively. The roller is rotatably connected to one end of the pressure plate and is in contact with the top wall of the conveyor belt. One end of the push block has an inclined structure and abuts against the other end of the pressure plate. The other end of the push block is fixedly connected to the slide plate, and one end of the push block has a groove for the telescopic rod to move.

[0012] Preferably, multiple baffles are spaced apart around the periphery of the conveyor belt, and side skirts are fixedly connected to both sides of the conveyor belt. The bottom of the baffles and the bottom of the side skirts are in contact with the top of the support belt. A pair of pressure rollers are rotatably connected to the inner wall of the housing, and the bottom of the two pressure rollers are in contact with the top of the conveyor belt and the bottom wall of the conveyor belt, respectively.

[0013] Preferably, the assembly further includes a motor and a braking component.

The slide is fixedly connected to the side wall of the housing, and the stop bar passes through the slide and is slidably connected to it. The stop bar has an L-shaped rod structure. When the bottom of the stop bar abuts against the bottom wall of the slide, the stop bar separates from the pawl, and the pawl can limit the rotation direction of the ratchet. When the bottom of the stop bar abuts against the inner wall of the slide, the top of the stop bar abuts against the bottom of the pawl, the pawl separates from the ratchet, and the ratchet can rotate freely.

[0014] Preferably, it also includes a tension assembly, which includes a pair of sliders, a pair of bearing seats, a threaded rod, a guide rod, and a motor. The sliders pass through the sidewall of the housing and are slidably connected thereto. The two sliders are rotatably connected to both ends of the second drive roller, respectively.

The motor is fixedly connected to the sliders. The output shaft of the motor passes through the sliders and is coaxially connected to the threaded rod.

[0015] The beneficial effects of this invention are: 1. This invention optimizes the conveyor belt support structure through stabilizing support components, replacing traditional line contact with surface contact, significantly improving conveying stability and reducing vibration. Multiple equidistantly distributed stabilizing support components provide comprehensive support for the conveyor belt's return section, ensuring complete contact between the support belt and the bottom of the conveyor belt. This increases the contact area while dispersing the force on the belt, effectively suppressing vibrations caused by gravity and inertia. By rotating the screw in conjunction with the adjusting mechanism, the rotating seat moves the support rollers, allowing for flexible adjustment of the support belt tension. This ensures the support belt remains in close contact with the conveyor belt, adapting to the conveying needs of materials of varying weights.

[0016] 2. This invention achieves real-time adaptive correction of conveyor belt misalignment through an active correction component, solving the problem of belt deviation at its source. The rollers of the trigger mechanism are in real-time contact with the top of the conveyor belt. When uneven material distribution causes the conveyor belt to tilt, the rollers on one side are squeezed, causing the pressure plate to move downward. The inclined surfaces of the pressure plate and the push block push the slide plate to slide. The slide plate drives the bottom plate and the first toothed ring to rotate through the fisheye groove transmission between the cam shaft and the rotating shaft. Then, the meshing of the first toothed ring and the second toothed ring drives the rotating frame and the correction roller to deflect, applying a reverse correction force to the conveyor belt. The tension spring can pull the slide plate to reset after the conveyor belt returns to horizontal, realizing the automatic return of the correction mechanism. Compared with the traditional passive limit solution, the correction is more timely and accurate, and can avoid additional wear and extend the service life of the conveyor belt. At the same time, multiple sets of active correction components work together to further improve the anti-deviation effect. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] like Figures 1 to 13 As shown: A segmented conveyor with a stable structure includes a housing 1 and a support frame 10. The top of the support frame 10 is fixedly connected to the bottom of the housing 1. The housing 1 has an L-shaped inclined structure. It also includes a first drive roller 11, a second drive roller 12, a conveyor belt 13, a stabilizing support assembly 2, and an active correction assembly 3. The first drive roller 11 and the second drive roller 12 are rotatably connected to the inner wall of the housing 1. The conveyor belt 13 is wound around the periphery of the first drive roller 11 and the second drive roller 12 and rotates synchronously with them. The stabilizing support assembly 2 includes a pair of support rollers 20 and a support belt 21. The support rollers 20 are rotatably connected to the inner wall of the housing 1. The support belt 21 is wound around the periphery of the two support rollers 20 and rotates synchronously with them. The top of the support belt 21 is in contact with the bottom of the conveyor belt 13. The active correction assembly 3 is installed on the housing 1 and is used to actively correct the deviation of the conveyor belt 13.

[0037] Before the equipment is put into operation, the tension of the support belt 21 of the stabilizing support assembly 2 is adjusted by adjusting mechanism 24: rotating screw 240, the screw 240 and the fixed block 241 are threaded together to push rotating seat 23 to slide along the side wall of housing 1. Rotating seat 23 drives the corresponding support roller 20 to move until the support belt 21 is taut and tightly attached to the bottom of conveyor belt 13. Multiple equidistantly distributed stabilizing support assemblies 2 can form a continuous supporting surface to ensure that the force on the return section of conveyor belt 13 is uniform. At the same time, the tension of conveyor belt 13 is adjusted by tension assembly 6. Starting motor 64 drives threaded rod 62 to rotate. Threaded rod 62 and bearing seat 61 are threaded together to push slider 60 to slide. Slider 60 drives second drive roller 12 to move. With the guidance of guide rod 63, the tension of conveyor belt 13 is precisely adjusted to adapt to different material conveying needs.

[0038] The motor 15 is started, and its output shaft drives the first drive roller 11 to rotate. The first drive roller 11 and the second drive roller 12 work together to drive the conveyor belt 13. The material is placed on the conveyor belt 13, and the baffle 130 prevents the material from sliding. The side skirt 131 prevents the material from spilling from both sides of the conveyor belt 13. During the operation of the conveyor belt 13, the support belt 21 of the stabilizing support assembly 2 rotates synchronously with the conveyor belt 13, providing support to the conveyor belt 13 in a surface contact manner. Compared with traditional line contact support, this greatly increases the contact area, effectively disperses the belt pressure, suppresses the vibration of the conveyor belt 13 caused by gravity and inertia, and improves the conveying stability.

[0039] like Figures 1 to 6 As shown: There are multiple stabilizing support components 2, which are distributed at equal intervals. Each stabilizing support component 2 also includes a pair of support seats 22, a pair of rotating seats 23, and a pair of adjusting mechanisms 24. The support seats 22 are fixedly connected to the bottom of the housing 1 and are rotatably connected to both ends of one of the support rollers 20. The rotating seats 23 pass through the side wall of the housing 1 and are slidably connected to it. The rotating seats 23 are rotatably connected to both ends of the other support roller 20. The adjusting mechanisms 24 are installed on the housing 1 and are used to maintain the tension of the support belt 21.

[0040] The adjusting mechanism 24 includes a screw 240 and a fixing block 241. The fixing block 241 is fixedly connected to the housing 1. The screw 240 passes through the fixing block 241 and is threadedly connected to it. The screw 240 is rotatably connected to the rotating seat 23.

[0041] When the support belt 21 becomes loose after long-term use, the screw 240 can be rotated again to adjust the position of the support roller 20, ensuring that the support belt 21 is always taut and preventing increased vibration of the conveyor belt 13 due to the looseness of the support belt 21. The support seat 22 is a fixed end, ensuring the stability of the position of the support roller 20 on one side, while the sliding design of the rotating seat 23 provides space for tension adjustment. The structure is simple and easy to adjust, and it can be adapted to support belts 21 with different degrees of wear.

[0042] like Figures 3 to 10 As shown: There are multiple active correction components 3 located above the support roller 20 and near the end of the second drive roller 12. The active correction component 3 includes a support plate 30, a pair of rotating frames 31, a pair of correction rollers 32 and a pair of triggering mechanisms 4. The support plate 30 is fixedly connected to the inner wall of the housing 1. The rotating frames 31 are rotatably connected to the bottom of the support plate 30. The correction rollers 32 are rotatably connected to the inner wall of the rotating frames 31. The correction rollers 32 are located above the support roller 20 and are in contact with the bottom wall of the conveyor belt 13. The triggering mechanisms 4 are installed on the support plate 30 and are used to drive the correction rollers 32 to rotate according to the tilt angle of the conveyor belt 13.

[0043] The active correction assembly 3 also includes a base plate 33, a rotating shaft 34, a pair of first toothed rings 35 and a pair of second toothed rings 36. The middle part of the base plate 33 is fixedly connected to the rotating shaft 34. The rotating shaft 34 passes through the support plate 30 and is rotatably connected to it. The first toothed rings 35 are fixedly connected to both ends of the base plate 33. The second toothed rings 36 are fixedly connected to the rotating frame 31. The second toothed rings 36 and the first toothed rings 35 mesh with each other. The two first toothed rings 35 are centrally symmetrically distributed on both sides of the rotating shaft 34.

[0044] The active correction component 3 also includes a slide plate 37, a pair of tension springs 38, and a cam shaft 39. The slide plate 37 is slidably connected to the top of the support plate 30. The top of the slide plate 37 has a long groove 370 for the rotating shaft 34 to pass through. The rotating shaft 34 has an L-shaped structure and a fisheye groove 340 on its top. The cam shaft 39 is fixedly connected to the top of the slide plate 37. The cam shaft 39 passes through the fisheye groove 340 and is slidably connected to it. The two tension springs 38 are symmetrically arranged on both sides of the support plate 30. The opposite ends of the two tension springs 38 are fixedly connected to the slide plate 37, and the opposite ends of the two tension springs 38 are fixedly connected to the support plate 30.

[0045] Two triggering mechanisms 4 are symmetrically arranged on both sides of the support plate 30. The triggering mechanism 4 includes a telescopic rod 40, a spring 41, a pressure plate 42, a roller 43, and a push block 44. The bottom of the telescopic rod 40 is fixedly connected to the top of the support plate 30, and the telescopic end of the telescopic rod 40 is fixedly connected to the bottom of the pressure plate 42. The spring 41 is sleeved around the telescopic rod 40, and both ends of the spring 41 are fixedly connected to the bottom of the pressure plate 42 and the top of the support plate 30, respectively. The roller 43 is rotatably connected to one end of the pressure plate 42, and the roller 43 is in contact with the top wall of the conveyor belt 13. One end of the push block 44 has an inclined structure and abuts against the other end of the pressure plate 42. The other end of the push block 44 is fixedly connected to the slide plate 37. One end of the push block 44 has a groove 440 for the telescopic rod 40 to move.

[0046] When uneven material distribution causes the conveyor belt 13 to tilt to one side, the tilted conveyor belt 13 will exert downward pressure on the roller 43 of the corresponding triggering mechanism 4, pushing the pressure plate 42 down, the telescopic rod 40 retracts, and the spring 41 is compressed. During the downward movement of the pressure plate 42, its end interacts with the inclined surface of the push block 44, pushing the push block 44 to drive the slide plate 37 to slide along the support plate 30. One side of the tension spring 38 is stretched, and the other side of the tension spring 38 is compressed. When the slide plate 37 slides, the cam shaft 39 slides in the fish-eye groove 340 of the rotating shaft 34, driving the rotating shaft 34 to rotate around its own axis. The rotating shaft 34 drives the bottom plate 33 and the first toothed rings 35 at both ends to rotate synchronously. Since the two first toothed rings 35 are centrally symmetrically distributed, their rotation directions are opposite. Then, through the meshing of the first toothed ring 35 and the second toothed ring 36, the two rotating frames 31 are driven to deflect in opposite directions. The rotating frames 31 drive the straightening roller 32 to deflect, applying a reverse corrective thrust to the conveyor belt 13, so that the conveyor belt 13 gradually returns to a horizontal state.

[0047] Once the conveyor belt 13 returns to horizontal, the pressure on the inclined side disappears, the spring 41 rebounds and pushes the pressure plate 42 to reset, the resistance of the push block 44 is released, the tension spring 38 pulls the slide plate 37 to reset, and then drives the correction roller 32 back to center through the cam shaft 39, rotating shaft 34, toothed ring and other structures, completing one automatic correction cycle. Multiple sets of active correction components 3 work together to achieve real-time correction of the conveyor belt 13 throughout its entire stroke, ensuring stable conveying.

[0048] like Figures 11 to 13 As shown: Multiple baffles 130 are arranged at intervals around the periphery of the conveyor belt 13. Side skirts 131 are fixedly connected to both sides of the conveyor belt 13. The bottom of the baffles 130 and the bottom of the side skirts 131 are in contact with the top of the support belt 21. A pair of pressure rollers 14 are rotatably connected to the inner wall of the housing 1. The bottom of the two pressure rollers 14 are in contact with the top of the conveyor belt 13 and the bottom wall of the conveyor belt 13, respectively.

[0049] It also includes a motor 15 and a braking assembly 5. The motor 15 is fixedly connected to the side wall of the housing 1. The output shaft of the motor 15 passes through the side wall of the housing 1 and is coaxially connected to the first drive roller 11. The braking assembly 5 includes a ratchet 50, a pawl 51, a stop bar 52, and a slide 53. The ratchet 50 is coaxially connected to the first drive roller 11. One end of the pawl 51 is rotatably connected to the side wall of the housing 1, and the other end of the pawl 51 abuts against a protrusion on the ratchet 50. The slide 53 is fixedly connected to the side wall of the housing 1. The stop bar 52 passes through the slide 53 and is slidably connected to it. The stop bar 52 is an L-shaped rod structure. When the bottom of the stop bar 52 abuts against the bottom wall of the slide 53, the stop bar 52 separates from the pawl 51. The pawl 51 can limit the rotation direction of the ratchet 50. When the bottom of the stop bar 52 abuts against the inner wall of the slide 53, the top of the stop bar 52 abuts against the bottom of the pawl 51, the pawl 51 separates from the ratchet 50, and the ratchet 50 can rotate freely.

[0050] It also includes a tension assembly 6, which includes a pair of sliders 60, a pair of bearing seats 61, a threaded rod 62, a guide rod 63, and a motor 64. The sliders 60 pass through the side wall of the housing 1 and are slidably connected to it. The two sliders 60 are rotatably connected to both ends of the second drive roller 12, respectively. The bearing seats 61 are fixedly connected to the housing 1. The threaded rod 62 passes through the bearing seats 61 and is threadedly connected to them. The threaded rod 62 is rotatably connected to one of the sliders 60. The guide rod 63 is fixedly connected to the other slider 63. The guide rod 63 passes through the bearing seats 61 and is slidably connected to them. The motor 64 is fixedly connected to the sliders 60. The output shaft of the motor 64 passes through the sliders 60 and is coaxially connected to the threaded rod 62.

[0051] The baffle 130 and side skirt 131 not only prevent material spillage, but their bottom contact with the support belt 21 also further restricts the lateral displacement of the conveyor belt 13, helping to improve conveying stability and reducing vibration at the edges of the conveyor belt 13. A pair of pressure rollers 14 squeeze the top and bottom walls of the conveyor belt 13 respectively, causing it to bend naturally, thereby cooperating with the housing 1 to lift the material.

[0052] During normal operation, the stop lever 52 is raised so that its bottom contacts the inner wall of the slide block 53, and its top contacts the pawl 51, separating the pawl 51 from the ratchet 50. The ratchet 50 then rotates freely with the first drive roller 11 without affecting the operation of the equipment. When the equipment stops or requires emergency braking, the stop lever 52 is lowered so that its bottom contacts the bottom wall of the slide block 53, separating the stop lever 52 from the pawl 51. Under its own weight, the pawl 51 contacts the protrusion of the ratchet 50, restricting the ratchet 50 from rotating in the opposite direction. This prevents the first drive roller 11 from reversing, avoiding the conveyor belt 13 from sliding in the opposite direction due to the weight of the material, and improving equipment safety.

[0053] By driving the threaded rod 62 to rotate by the motor 64, the position of the second drive roller 12 can be precisely adjusted, thereby adjusting the tension of the conveyor belt 13, avoiding excessive wear due to excessive tension or slippage due to insufficient tension, and extending the service life of the conveyor belt 13.
