Belt conveyor

Abstract

This application discloses a belt conveyor including a base, flat idlers, inclined idlers, a detection component, and a synchronous drive mechanism. During operation, the flat idlers and the inclined idlers arranged on both sides together form the conveyor belt support structure, ensuring stable material transport. The detection component continuously monitors the tilt state of the flat and inclined idlers, capturing real-time attitude changes during equipment operation. When the conveyor belt shows a tendency to deviate or the idlers tilt abnormally, the detection component quickly sends a feedback signal. Upon receiving the signal, the synchronous drive mechanism starts, transmitting power through the transmission component to precisely drive the flat and inclined idlers to rotate synchronously relative to the base. By adjusting the tilt angle of the idlers, a directional corrective force is provided to the conveyor belt, causing the deviated conveyor belt to gradually return to its original position until the detection component detects that the idlers have returned to their normal tilt state. At this point, the synchronous drive mechanism stops operating, ensuring the continuous and stable operation of the conveyor.

Description

Technical Field

[0001] This application relates to the field of coal mine equipment technology, and in particular to a belt conveyor. Background Technology

[0002] Belt conveyors, as core material conveying equipment in coal, port, and metallurgical industries, are indispensable in industrial production logistics due to their advantages of strong conveying capacity, long distance, and low cost. They are particularly crucial in coal mining, undertaking the key task of raw coal transfer. However, due to multiple factors such as installation accuracy deviations, uneven belt tension, and material imbalance, belt misalignment is prone to occur during conveyor operation, affecting not only conveying efficiency but also potentially causing equipment failure.

[0003] Existing correction solutions mostly employ hydraulically driven adjustment of the support deflection, such as the patented technology with publication number CN106628936A. However, this method has significant drawbacks: support deflection easily narrows the conveyor channel, exacerbating belt compression and wear; hydraulic drive adjustment force is limited, response is slow, and correction accuracy is insufficient, easily leading to incomplete or over-correction; furthermore, the adjustment angle is limited, making it difficult to adapt to dynamic deviation conditions. These problems increase equipment maintenance costs and affect conveying continuity, necessitating a correction technology solution that is less damaging, more accurate, and more flexible in adjustment. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This part of the invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0009] In one feasible implementation, the detection component includes: A detection sensor is mounted on the base. A detection stop bar, one end of which is connected to the detection sensor, is arranged on the side of the inclined roller.

[0010] In one feasible implementation, the transmission assembly includes: The first transmission rod is arranged below the flat idler roller; The second transmission rod is arranged below the inclined roller; Multiple rotating connecting shafts are provided, wherein the first transmission rod is connected to the flat support roller via the rotating connecting shaft, and the second transmission rod is connected to the inclined support roller via the rotating connecting shaft; The driving component is connected to the first transmission rod and / or the second transmission rod.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: The belt conveyor provided in this application includes a base, flat idlers, inclined idlers, a detection component, and a synchronous drive mechanism. During operation, the flat idlers and the inclined idlers arranged on both sides together form the conveyor belt support structure, ensuring stable material transport. The detection component continuously monitors the tilt state of the flat and inclined idlers, capturing real-time attitude changes during equipment operation. When the conveyor belt shows a tendency to deviate or the idlers tilt abnormally, the detection component quickly sends a signal. Upon receiving the signal, the synchronous drive mechanism starts, transmitting power through the transmission component to precisely drive the flat and inclined idlers to rotate synchronously relative to the base. By adjusting the tilt angle of the idlers, a directional correction force is provided to the conveyor belt, causing the deviated conveyor belt to gradually return to its normal tilt state until the detection component detects that the idlers have returned to their normal tilt state. The synchronous drive mechanism then stops operating, ensuring continuous and stable operation of the conveyor. The belt conveyor provided in this application, on the one hand, utilizes the combined arrangement of flat and inclined idlers with a synchronous drive to specifically adjust the idler attitude, avoiding the rigid compression of the conveyor belt by traditional correction methods, significantly reducing conveyor belt wear, and extending equipment lifespan. On the other hand, the real-time monitoring of the detection components and the rapid response of the synchronous drive mechanism form a closed-loop control, which can promptly detect abnormal tilting of the idler rollers and accurately adjust the correction force and angle, effectively solving the problems of incomplete or excessive correction and improving conveying accuracy and stability. Furthermore, the synchronous drive mechanism links the flat and inclined idler rollers through the transmission components, ensuring consistent action, avoiding conveying imbalance caused by unilateral adjustment, guaranteeing continuous material conveying, and making it suitable for various complex working conditions, significantly improving the conveyor's operating efficiency and reliability.

[0022] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0023] like Figures 1 to 4As shown in the figure, this application proposes a belt conveyor, including: a base 1; a flat idler 2 and an inclined idler 3, the flat idler 2 being arranged above the base 1, and the inclined idler 3 being arranged on both sides of the flat idler 2, the inclined idler 3 being arranged at an angle relative to the flat idler 2; a detection component, the detection component being disposed on the base 1, for detecting the tilt state of the flat idler 2 and the inclined idler 3; and a synchronous drive mechanism 6, the synchronous drive mechanism 6 including a drive component 67 and a transmission component, the drive component 67 being connected to the flat idler 2 and the inclined idler 3 through the transmission component, the synchronous drive mechanism 6 being used to drive the flat idler 2 and the inclined idler 3 to rotate relative to the base 1.

[0024] The belt conveyor provided in this embodiment includes a base 1, flat idlers 2, inclined idlers 3, a detection component, and a synchronous drive mechanism 6. During operation, the flat idlers 2 and the inclined idlers 3 arranged on both sides together form the conveyor belt support structure, ensuring stable material transport. The detection component continuously monitors the tilt state of the flat idlers 2 and inclined idlers 3, capturing changes in the equipment's posture in real time. When the conveyor belt shows a tendency to deviate or the idlers tilt abnormally, the detection component quickly sends a feedback signal. Upon receiving the signal, the synchronous drive mechanism 6 activates its drive component 67 and transmits power through the transmission component, precisely driving the flat idlers 2 and inclined idlers 3 to rotate synchronously relative to the base 1. By adjusting the tilt angle of the idlers, a directional corrective force is provided to the conveyor belt, causing the deviated conveyor belt to gradually return to its original position until the detection component detects that the idlers have returned to their normal tilt state. At this point, the synchronous drive mechanism 6 stops operating, ensuring the continuous and stable operation of the conveyor. The belt conveyor provided in this application embodiment, on the one hand, utilizes a combination of flat idlers 2 and inclined idlers 3 with synchronous drive to selectively adjust the idler posture, avoiding the hard compression of the conveyor belt by traditional correction methods, significantly reducing conveyor belt wear, and extending equipment service life. On the other hand, the real-time monitoring by the detection component and the rapid response of the synchronous drive mechanism 6 form a closed-loop control, which can promptly detect abnormal idler tilting, accurately adjust the correction force and angle, effectively solve the problems of incomplete or excessive correction, and improve conveying accuracy and stability. Furthermore, the synchronous drive mechanism 6 links the flat idlers 2 and inclined idlers 3 through the transmission component, ensuring consistent action, avoiding conveying imbalance caused by unilateral adjustment, ensuring continuous material conveying, and is suitable for various complex working conditions, significantly improving the operating efficiency and reliability of the conveyor.

[0025] like Figures 1 to 4 As shown, in one feasible embodiment, the base 1 includes: a first support 11 and a second support 12, the second support 12 being disposed on the first support 11; a plurality of roller brackets 4, the roller brackets 4 being rotatably connected to the second support 12, and flat rollers 2 and inclined rollers 3 being disposed on the roller brackets 4.

[0026] This technical solution further provides the structural composition of the base 1, which may include a first support 11, a second support 12, and multiple idler roller brackets 4. The layered layout of the first support 11 and the second support 12 provides a stable installation foundation for the idler roller assembly, while facilitating overall equipment assembly and subsequent maintenance, reducing installation and commissioning difficulty, and improving equipment operation and maintenance convenience. The design of the idler roller brackets 4 being rotatably connected to the second support 12 allows the flat idler roller 2 and the inclined idler roller 3 to flexibly adjust their tilt angles, breaking free from the limitations of fixed structures. This allows for precise adaptation to different degrees of conveyor belt misalignment, significantly improving the flexibility and adaptability of correction. The arrangement of the idler rollers and idler roller brackets 4 ensures the structural stability of the idler rollers during rotation, avoiding component loosening or damage caused by uneven force on one side, and extending the service life of the equipment. In addition, the cooperation between the layered supports and the rotatable brackets ensures that the idler rollers maintain support stability during adjustment, without narrowing the conveyor belt passage, reducing compression and wear on the conveyor belt, ensuring the continuity and safety of material conveying, and making it suitable for complex and demanding industrial conveying scenarios such as coal mines.

[0027] like Figures 1 to 4 As shown, in one feasible embodiment, the base 1 includes: a connecting plate 15, which is arranged on both sides of the base 1; and a connecting slot 151, which is formed on the connecting plate 15, and a fastening bolt passes through the connecting slot 151 and is connected to the second support 12.

[0028] In this technical solution, the base 1 may also include a connecting plate 15 and a connecting slot 151. The design of the connecting plates 15 on both sides of the base 1 and the connecting slot 151, with fastening bolts, provides a convenient and precise solution for adjusting the height of the flat idler 2 and the inclined idler 3. By loosening the fastening bolts, the installation height of the second support 12 can be flexibly adjusted along the vertical stroke of the connecting slot 151, thereby simultaneously changing the support height of the flat idler 2 and the inclined idler 3. This structure does not require disassembling complex parts, and the adjustment operation is simple and efficient. It can quickly adapt to conveyor belts of different thicknesses or different material conveying needs, ensuring that the conveyor belt is always in the optimal support state. At the same time, the bolt fastening combined with slot positioning ensures strong structural stability after adjustment, avoiding height deviation from affecting conveying accuracy and effectively improving the adaptability of the equipment to diverse working conditions.

[0029] like Figures 1 to 4 As shown, in one feasible embodiment, the detection component includes: a detection sensor 7, which is disposed on the base 1; and a detection stop bar 8, one end of which is connected to the detection sensor 7 and arranged on the side of the inclined roller 3.

[0030] In this technical solution, the detection stop bar 8 is precisely positioned on the side of the inclined idler roller 3, directly capturing the contact signal when the conveyor belt deviates. Combined with the detection sensor 7 on the base 1, it can quickly respond to the deviation status, avoiding signal delays that could lead to untimely correction. Its structure is simple and its installation position is reasonable, not occupying space in the conveyor channel and not interfering with material conveying. Simultaneously, through direct contact detection, it can accurately identify the direction and degree of deviation, providing reliable signal support for the synchronous drive mechanism 6, ensuring that the correction action accurately adapts to the deviation situation, effectively solving the problem of insufficient accuracy in traditional detection methods, and improving the operational stability of the conveyor.

[0031] like Figures 1 to 4 As shown, in one feasible embodiment, the transmission assembly includes: a first transmission rod 61, which is arranged below the flat idler roller 2; a second transmission rod 62, which is arranged below the inclined idler roller 3; and a plurality of rotary connecting shafts 5, wherein the first transmission rod 61 is connected to the flat idler roller 2 via the rotary connecting shafts 5, and the second transmission rod 62 is connected to the inclined idler roller 3 via the rotary connecting shafts 5; wherein a driving member 67 is connected to the first transmission rod 61 and / or the second transmission rod 62.

[0032] This technical solution further provides the structural composition of the transmission assembly, which may include a first transmission rod 61, a second transmission rod 62, and multiple rotating connecting shafts 5. During belt conveyor operation, the first transmission rod 61 is positioned below the flat idler 2, and the second transmission rod 62 is positioned below the inclined idler 3, forming a precise transmission layout. When the detection assembly detects belt misalignment or idler tilting, the drive unit 67 starts and outputs power to the first transmission rod 61 and / or the second transmission rod 62. The power is transmitted to each rotating connecting shaft 5 via the transmission rods, and then the rotating connecting shafts 5 drive the corresponding flat idler 2 or inclined idler 3 to rotate synchronously. By coordinating the adjustment of the tilt angles of the flat idler 2 and the inclined idler 3, a directional correction force is generated, pushing the conveyor belt back to its original position until the equipment returns to normal operation, at which point the drive unit 67 stops working.

[0033] In this technical solution, the transmission assembly achieves precise power transmission through the cooperation of split transmission rods and rotating connecting shaft 5. On one hand, the transmission rods are arranged one-to-one with the idlers, resulting in a short transmission path, low loss, and guaranteed driving efficiency, allowing for faster idler response. On the other hand, the drive component 67 can flexibly connect single or multiple transmission rods, enabling simultaneous adjustment of the flat idler 2 and the inclined idler 3, as well as targeted fine-tuning to adapt to different deviation scenarios and improve correction flexibility. Furthermore, the overall structure is simple and compact, facilitating installation and maintenance, avoiding potential malfunctions caused by complex transmissions, while ensuring consistent idler movement, reducing uneven conveyor belt stress, extending equipment lifespan, and ensuring continuous conveying.

[0034] like Figures 1 to 4As shown, in one feasible embodiment, the transmission assembly includes: a plurality of first transmission teeth 65, which are sleeved on the first transmission rod 61 and the second transmission rod 62; and a plurality of second transmission teeth 66, which are disposed on the rotary connecting shaft 5, and the first transmission teeth 65 mesh with the second transmission teeth 66.

[0035] In this technical solution, the transmission component may further include a first transmission gear 65 and a second transmission gear 66. The meshing transmission of the first transmission gear 65 and the second transmission gear 66 features a precise transmission ratio and low power loss, efficiently transmitting the power of the drive component 67 to the rotating connecting shaft 5. This ensures rapid response and precise angle adjustment of the flat idler roller 2 and the inclined idler roller 3, effectively improving the correction accuracy and avoiding the problem of incomplete correction caused by power transmission deviation in traditional transmission methods. On the other hand, the corresponding assembly structure of the first transmission gear 65 connecting to the first transmission rod 61 and the second transmission rod 62, and the second transmission gear 66 connecting to the rotating connecting shaft 5, ensures that the driving force of each idler roller is balanced and stable, guaranteeing that the flat idler roller 2 and the two inclined idler rollers 3 rotate synchronously, avoiding secondary deviation of the conveyor belt caused by unilateral force imbalance, and further improving the conveying stability. Furthermore, the gear transmission structure has high strength and good wear resistance, making it suitable for complex and harsh industrial conditions such as coal mines. It can reduce potential failures during long-term operation, extend the service life of the transmission component, and reduce equipment maintenance costs. Meanwhile, the meshing structure is simple and compact, which facilitates installation, commissioning and subsequent maintenance, and improves the overall ease of operation and maintenance of the equipment.

[0036] like Figures 1 to 4 As shown, in one feasible embodiment, the drive member 67 is connected to the first transmission rod 61. The transmission assembly further includes a transmission member, through which the first transmission rod 61 is connected to the second transmission rod 62.

[0037] In this technical solution, during the operation of the belt conveyor, the detection component monitors the status of the conveyor belt and idlers in real time. When the conveyor belt deviates and triggers a detection signal, the drive component 67 connected to the first transmission rod 61 starts. Power is transmitted to the transmission component via the first transmission rod 61, and then the transmission component drives the second transmission rods 62 on both sides to operate synchronously. Through the gear meshing structure of the transmission component, power is transmitted to the rotating connecting shaft 5, which drives the flat idler 2 and the two inclined idler rollers 3 to rotate synchronously to adjust the tilt angle, generating a directional correction force to push the conveyor belt back to its original position. After resetting, the drive component 67 stops working, ensuring stable conveying.

[0038] In this technical solution, the drive component 67 is connected to the first transmission rod 61, and the transmission component links the second transmission rod 62. On the one hand, the single drive component 67 is used in a centralized drive mode, and multiple transmission rods are synchronously linked through the transmission component to ensure that the flat idler 2 and the two inclined idler rollers 3 move at the same height. This avoids the imbalance of force on the conveyor belt caused by unilateral adjustment, significantly improves the correction accuracy, and completely solves the problems of incomplete or excessive correction in traditional solutions. On the other hand, the setting of the transmission component effectively adapts to the spatial arrangement requirements of the transmission rods, realizes stable and efficient power transmission, reduces power loss, and makes the idler rollers respond more quickly. It can quickly adapt to the dynamic deviation of the conveyor belt and improve the correction efficiency under complex working conditions. Furthermore, the single-drive transmission component linkage structure simplifies the overall layout, reduces the number of drive components, reduces equipment manufacturing costs and potential failures, and the transmission structure has high strength and stability, which can withstand the long-term test of harsh working conditions such as coal mines. At the same time, this design does not require adjustment of the overall position of the support, avoids narrowing of the conveyor channel, reduces the squeezing and wear on the conveyor belt, extends the service life of the equipment, and ensures the continuity and stability of logistics transportation.

[0039] like Figures 1 to 4 As shown, in one feasible implementation, the transmission component includes a universal joint 64 or a bevel gear. This configuration, using a universal joint 64 or a bevel gear as the transmission component, provides an efficient and adaptable power transmission solution for the transmission assembly. The universal joint 64 has angle compensation capabilities, flexibly adapting to spatial arrangement deviations between the first transmission rod 61 and the second transmission rod 62, ensuring smooth power transmission even in non-collinear transmission. The bevel gear achieves precise conversion of power direction through meshing transmission, adapting to vertical or cross-arranged transmission scenarios. Both ensure efficient power transmission from the drive component 67 to each transmission rod, guaranteeing synchronous operation of the flat idler roller 2 and the inclined idler roller 3, and improving consistency in alignment. Simultaneously, both types of transmission components have high structural strength and good wear resistance, are suitable for complex industrial conditions, and are easy to install and maintain, reducing potential transmission failures and further improving the operational stability and service life of the belt conveyor.

[0040] In one feasible embodiment, the belt conveyor further includes: a telescopic slide bar 13, with a sliding cavity formed at the end of the base 1, and one end of the telescopic slide bar 13 disposed in the sliding cavity; and a connector 14 connected to the other end of the telescopic slide bar 13.

[0041] In this technical solution, the belt conveyor also includes a telescopic slide bar 13 and a connector 14. During installation, the extension length of the telescopic slide bar 13 within the sliding cavity at the end of the base 1 is adjusted according to the installation position requirements of the belt conveyor. After determining the position, it is locked in place using fixing screws. Then, using the connector 14 at the other end of the telescopic slide bar 13, the base 1 is precisely connected to the conveyor frame and fixed with bolts and other fasteners, quickly achieving the installation and positioning of the belt conveyor and adapting to different installation spacing requirements. The design of the telescopic slide bar 13 and the sliding cavity allows for flexible adjustment of the installation spacing of the base 1. The connector 14 can quickly adapt to conveyor frames of different specifications, significantly improving the equipment's installation adaptability. No additional processing of adaptable parts is required, simplifying the installation process and reducing construction difficulty and cost. At the same time, the telescopic slide bar 13 is structurally stable after being locked, ensuring the stability of the idler roller support and preventing the correction effect from being affected by loose installation during operation, thus ensuring the long-term reliable operation of the conveying equipment.

[0042] Example like Figures 1 to 4 As shown, the belt conveyor provided in this application embodiment includes a base 1, which is used to fix it on the belt conveyor. The base 1 includes a first support 11 and a second support 12 disposed on the upper side of the first support 11. The second support 12 is an inverted trapezoid adapted to the conveyor belt. A horizontally arranged flat idler roller 2 is disposed in the middle of the upper side of the second support 12. An inclined idler roller 3 is disposed at both ends of the flat idler roller 2 in the axial direction. The inclined idler roller 3 gradually tilts away from the center of the base 1 from bottom to top. The flat idler roller 2 and the inclined idler rollers 3 at both ends constitute a support structure for the conveyor belt to pass through.

[0043] See Figures 1-4The flat idler roller 2 and the inclined idler roller 3 are provided with idler roller brackets 4 that cooperate with them. The bottom of the idler roller bracket 4 is rotatably mounted on the second support 12 via a rotating connecting shaft 5. The rotating connecting shafts 5 are synchronously driven by a synchronous drive mechanism 6. Detection sensors 7 are also provided on both sides of the base 1. Detection sensors 7 are provided with detection stops 8. The detection stops 8 are vertically mounted next to the inclined idler roller 3. The detection sensors 7 are controlled and connected to the synchronous drive mechanism 6. The conveyor belt passes over the flat idler 2 and the inclined idler 3. Under normal conditions, the conveyor belt does not contact the detection bars 8 on both sides. When the conveyor belt deviates to one side, the side of the conveyor belt will contact the detection bar 8. The detection sensor 7 receives the displacement signal, thereby controlling the synchronous drive mechanism 6 to start. The synchronous drive mechanism 6 drives the flat idler 2 and the inclined idler 3 to rotate around their respective rotating connecting shafts 5 at the same time, so that the flat idler 2 and the inclined idler 3 tilt according to the signal of the detection sensor 7. When the conveyor belt passes over the flat idler 2 and the inclined idler 3, the tilted flat idler 2 and the inclined idler 3 will drive the conveyor belt to reset, automatically correcting the deviation and preventing the conveyor belt from running off-track. This application achieves the correction of the conveyor belt by controlling the flat idler 2 and the inclined idler 3 to rotate at the same time. During the correction process, the compression of the conveyor belt is small, the damage to the conveyor belt is smaller, it is less likely to affect the logistics transportation, and the adjustment is flexible and the correction accuracy is high.

[0044] Specifically, the synchronous drive mechanism 6 includes a first transmission rod 61 parallel to the flat idler roller 2, second transmission rods 62 parallel to the inclined idler rollers 3 on both sides, and a drive member 67. The first transmission rod 61, the second transmission rod 62, and the second transmission rod 63 are rotatably mounted on the second support 12 and are synchronously connected via universal joints 64. Each of the first transmission rods 61, the second transmission rod 62, and the second transmission rod 63 is provided with a first transmission tooth 65, and each rotating connecting shaft 5 is provided with a second transmission tooth 66 for transmission connection with the first transmission tooth 65. The drive member 67 is transmissionally connected to the first transmission rod 61. When the drive member 67 drives the first transmission rod 61 to rotate, the universal joints 64 at both ends of the first transmission rod 61 drive the second transmission rods 62 to rotate synchronously, and the first transmission teeth 65 and the second transmission teeth 66 cooperate to drive the rotating connecting shafts 5 to rotate, thereby causing the flat idler roller 2 and the inclined idler roller 3 to swing.

[0045] Among them, the drive component 67 is mainly composed of a servo motor and a reduction gear, which enables precise control.

[0046] See Figure 1 , Figure 4 In this embodiment, the base 1 includes a first support 11 and a second support 12 disposed on the upper side of the first support 11. The second support 12 is in the shape of an inverted trapezoid adapted to the conveyor belt. The idler roller bracket 4 is rotatably disposed on the second support 12 via a rotating connecting shaft 5. Among them, see Figure 1, Figure 4 The first support 11 has telescopic slide rods 13 at both ends, and a sliding cavity adapted to the telescopic slide rods 13 is provided on the first support 11. The telescopic slide rods 13 are slidably disposed in the sliding cavity, and a connecting member 14 is provided at the end of the telescopic slide rods 13. The position of the connecting member 14 can be adjusted by controlling the extension and retraction of the telescopic slide rods 13 to meet various fixing requirements.

[0047] In order to fix the telescopic slide rod 13, a fixing screw for cooperating with the telescopic slide rod 13 is also provided on the first support 11. After passing through the first support 11, the fixing screw abuts against the outer wall of the telescopic slide rod 13, thereby fixing the position of the telescopic slide rod 13.

[0048] See Figure 1 The first support 11 has vertically arranged connecting plates 15 on its front and rear sides, and the second support 12 is located between the two connecting plates 15. Vertically arranged connecting slots 151 are formed on the connecting plates 15. Fastening bolts pass through the connecting slots 151 and are then fixedly connected to the second support 12. The height of the second support 12 can be adjusted by fixing the fastening bolts at different heights in the connecting slots 151, meeting various usage requirements.

[0049] The automatic correction idler structure of the coal mine belt conveyor of the present invention has the following working principle: The conveyor belt passes over the flat idler 2 and the inclined idler 3. Under normal conditions, the conveyor belt does not contact the detection stops 8 on both sides. When the conveyor belt deviates to the right, the right side of the conveyor belt will contact the detection stop 8 on the right side. The detection sensor 7 on the right side receives the displacement signal, thereby controlling the synchronous drive mechanism 6 to start. The synchronous drive mechanism 6 drives the flat idler 2 and the inclined idler 3 to rotate counterclockwise around their respective rotating connecting shafts 5, so that the flat idler 2 and the inclined idler 3 tilt counterclockwise. When the conveyor belt passes over the flat idler 2 and the inclined idler 3, the tilted flat idler 2 and the inclined idler 3 will generate a correction force that drives the conveyor belt to move away from the right side, thereby resetting the conveyor belt. After the right side of the conveyor belt no longer contacts the detection stop 8, the synchronous drive mechanism 6 controls the flat idler 2 and the inclined idler 3 to reset. When the conveyor belt deviates to the left, the left side of the conveyor belt will contact the detection stop bar 8 on the left. The detection sensor 7 on the left receives the displacement signal, thereby controlling the synchronous drive mechanism 6 to start. The synchronous drive mechanism 6 drives the flat idler 2 and the inclined idler 3 to rotate clockwise around their respective rotating connecting shafts 5, so that the flat idler 2 and the inclined idler 3 tilt clockwise. When the conveyor belt passes over the flat idler 2 and the inclined idler 3, the inclined flat idler 2 and the inclined idler 3 will generate a correction force to drive the conveyor belt to move away from the left, thereby resetting the conveyor belt. After the left side of the conveyor belt no longer contacts the detection stop bar 8, the synchronous drive mechanism 6 controls the flat idler 2 and the inclined idler 3 to reset.

[0050] The belt conveyor provided in this application addresses the technical problems of existing belt conveyor correction equipment, such as significant conveyor belt damage, low correction accuracy, inflexible adjustment, and disruption to logistics transportation. By setting up a combined support structure of synchronously rotating flat and inclined idlers, and coordinating the control of detection sensors and a synchronous drive mechanism, precise and gentle correction of misaligned conveyor belts is achieved, reducing compression damage to the conveyor belt, improving correction flexibility and accuracy, and ensuring the continuity of logistics transportation.
