Description

Technical Field

[0001] This application belongs to the technical field of belt conveyors, and specifically relates to a belt conveyor alignment device. Background Technology

[0002] Belt conveyors are primarily used for transporting bulk materials and are widely used in metallurgy, mining, and other fields. During operation, belt misalignment can occur due to factors such as frame installation deviations, belt adhesion, and material sticking to idlers. Severe misalignment can lead to belt edge damage and tearing, affecting the service life of the belt conveyor and even preventing the transported material from reaching its designated location. To correct belt misalignment, belt conveyors are typically equipped with a belt alignment device. This device adjusts the belt's direction, reducing belt damage and material delays caused by misalignment.

[0003] In related technologies, such as Chinese utility model patent CN217837103U, an intelligent heavy-duty belt alignment device is disclosed. It includes a support frame, a connecting frame mounted on the support frame, a detection wheel mounted on the connecting frame, a PLC control console mounted on the support frame, a hydraulic cylinder mounted on the connecting frame, and a guide roller rotatably connected to the support frame. The piston rod of the hydraulic cylinder is connected to the guide roller. When the conveyor belt deviates, the belt contacts the detection wheel, causing the detection wheel to send a signal to the PLC control console. This, in turn, causes the PLC control console to send a signal to the hydraulic cylinder, driving the piston rod of the hydraulic cylinder to drive the guide roller. This causes the guide roller to rotate relative to the support frame, thus adjusting the belt alignment using the guide roller. To facilitate power supply to the PLC control console, the device also discloses that the detection wheel includes a rotating wheel, a second rotating shaft, a first gear, a rotary encoder, and a power generation unit. The power generation unit includes a battery, a generator, a third rotating shaft, and a second gear. When the conveyor belt deviates... At this time, the conveyor belt contacts the rotating wheel, which drives the second shaft to rotate. The second shaft drives the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the third shaft to rotate, and the third shaft drives the input shaft of the generator to rotate. This causes the generator to generate electricity and send the electrical energy to the battery for storage. The battery is electrically connected to the PLC control console to facilitate power supply to the PLC control console. However, since the conveyor belt only contacts the rotating wheel when it deviates from its path, causing the wheel to rotate and enabling the generator to power the battery, if the conveyor belt does not contact the rotating wheel for a long time, the generator will not be able to power the battery for a long time, which can easily lead to battery depletion and damage, thus affecting the battery's service life. At the same time, because it uses a hydraulic cylinder to adjust the guide roller, the rotation response of the guide roller is slow, which affects the efficiency of adjusting the conveyor belt deviation. Utility Model Content

[0004] This application provides a belt alignment device for a belt conveyor to ensure the service life of the battery and improve the belt alignment efficiency.

[0005] The technical solution adopted in this application is as follows:

[0006] A belt conveyor alignment device includes:

[0007] Support frame;

[0008] The alignment assembly includes a roller frame rotatably connected to the support frame and an alignment roller rotatably connected to the roller frame.

[0009] An electric drive assembly, which is disposed on the support frame and is used to drive the roller frame to rotate;

[0010] A belt misalignment switch is provided on the support frame and located on both sides of the conveyor belt;

[0011] The power generation assembly includes a power generation roller rotatably connected to the support frame, a generator disposed on the support frame, and a storage battery disposed on the support frame. The power generation roller is used to support the conveyor belt and is drively connected to the input shaft of the generator. The generator is electrically connected to the storage battery, and the storage battery is electrically connected to the electric drive assembly and the belt misalignment switch.

[0012] By adopting the above technical solution, when using the belt alignment device of this application, it needs to be installed on the belt conveyor so that both the alignment idler and the power generation idler are located at the bottom of the belt, and both the alignment idler and the power generation idler are in contact with the belt, thereby enabling both the alignment idler and the power generation idler to support the belt, and the belt deviation switch is located on both sides of the belt; when the belt of the belt conveyor moves to transport materials, since the power generation idler is located at the bottom of the belt and in contact with the belt, the power generation idler is thus able to support the belt. The downward rotation of the generator roller drives the input shaft of the generator to rotate, so that the generator produces electrical energy and transmits the electrical energy to the battery for storage. When the conveyor belt deviates, one side of the conveyor belt contacts the deviation switch, so that the deviation switch drives the electric drive component. Under the action of the electric drive component, the roller frame drives the adjusting roller and the support frame to rotate relative to each other, so that the adjusting roller and the conveyor belt are set at an angle. Thus, the conveyor belt gradually returns to the set position under the action of the adjusting roller, so as to achieve the deviation adjustment of the conveyor belt.

[0013] Because the battery in this application is electrically connected to the belt misalignment switch and the electric drive assembly, the battery can be used to power the belt misalignment switch and the electric drive assembly, thus avoiding the need for an additional power supply to power the belt misalignment switch and the electric drive assembly, thereby reducing the energy consumption of the belt conveyor. Furthermore, because the idler frame is driven by the electric drive assembly in this application, compared with the prior art scheme that uses a hydraulic cylinder to drive the idler frame, the driving efficiency of the idler frame when the belt misaligns is improved, thereby improving the response efficiency of the belt adjustment device when the belt misaligns, and thus improving the belt adjustment efficiency.

[0014] Furthermore, since the generator roller in this application is used to support the conveyor belt, it can maintain rotation under the action of the conveyor belt during belt movement. This ensures that the generator remains in a power-generating state throughout the conveyor belt's movement. Compared to the prior art, where the generator only generates electricity when the conveyor belt deviates from its designated path, the solution in this application can continuously generate electricity for the battery, preventing potential battery depletion and thus ensuring the battery's lifespan. This, in turn, ensures the normal operation of the belt alignment device and reduces the usage and maintenance costs of the belt alignment device.

[0015] Optionally, the electric drive assembly includes an electric cylinder disposed on the support frame and a fixed arm disposed on the roller frame, wherein the piston rod of the electric cylinder is hinged to the end of the fixed arm away from the roller frame.

[0016] By adopting the above technical solution, when the conveyor belt deviates, one side of the conveyor belt contacts the deviation switch. The deviation switch sends a signal to the electric cylinder, which in turn causes the piston rod of the electric cylinder to extend or retract according to the signal sent by the deviation switch. This causes the piston rod to drive the fixed arm to move, and the fixed arm to drive the idler frame to move, causing the idler frame and the support frame to rotate relative to each other. As a result, the idler frame rotates to the set position according to the signal sent by the deviation switch. The adjusting idler then follows the idler frame to the set position. At this time, the adjusting idler applies resistance to the conveyor belt to continue moving in the deviation direction, so that the conveyor belt deviates towards the correct position under the action of the deviation idler, thereby achieving the deviation adjustment of the conveyor belt.

[0017] In this application, an electric cylinder is used to drive the idler frame, which improves the response efficiency of the belt alignment device and thus improves the belt alignment efficiency compared to the prior art that uses a hydraulic cylinder to drive the idler frame.

[0018] Optionally, the power generation assembly further includes a gearbox, one end of the power generation roller is driven to the input shaft of the gearbox, the output shaft of the gearbox is driven to the input shaft of the generator, and the rotational speed of the input shaft of the gearbox is less than the rotational speed of the output shaft of the gearbox.

[0019] By adopting the above technical solution, since one end of the generator roller is driven to the input shaft of the gearbox, and the output shaft of the gearbox is driven to the input shaft of the generator, and the speed of the input shaft of the gearbox is less than the speed of the output shaft of the gearbox, the speed of the generator input shaft can be increased by the gearbox to meet the generator's speed requirements, thereby ensuring the generator's power output and further preventing the battery from being depleted, thus further ensuring the battery's service life.

[0020] Optionally, both ends of the generator roller are provided with retaining edges, which extend circumferentially along the generator roller and are located outside the deviation switch.

[0021] By adopting the above technical solution, since both ends of the generator roller are equipped with retaining edges that extend circumferentially along the generator roller, the retaining edges can be used to block the conveyor belt when it runs off track or the electric cylinder malfunctions, thereby preventing the conveyor belt from continuing to move toward the off track position.

[0022] Optionally, the generator roller includes a rotating shaft and a roller sleeved outside the rotating shaft. An electromagnet electrically connected to the battery is provided outside the rotating shaft. The electromagnet has an energized state and an de-energized state. When the electromagnet is energized, it can generate a magnetic attraction force on the roller, so that the rotating shaft can rotate with the roller under the action of the electromagnet. The rotating shaft is driven to the input shaft of the generator.

[0023] By adopting the above technical solution, after the belt conveyor is installed, the belt contacts the rollers. When the belt moves, the rollers rotate under the action of the belt. At the same time, the battery supplies power to the electromagnet, which in turn energizes the electromagnet and generates a magnetic attraction force. This causes the rotating shaft to rotate with the rollers under the magnetic attraction force of the electromagnet. The rotating shaft then drives the input shaft of the generator to rotate, and the generator generates electricity for the battery. As the working time of the belt conveyor increases, the battery stores more and more electricity under the action of the generator. When the battery is fully charged, it stops supplying power to the electromagnet, and the electromagnet is de-energized. This causes the electromagnet to lose its magnetic attraction force on the rollers, and the rotating shaft can no longer rotate synchronously with the rollers. This causes the rollers and the rotating shaft to rotate relative to each other, and the input shaft of the generator is stationary, so that the generator stops generating electricity for the battery. This avoids the situation where the generator continuously generates electricity for the battery, which would affect the battery's service life, and further ensures the battery's service life.

[0024] Optionally, the power generation roller further includes a central cylinder fixedly connected to the rotating shaft. The central cylinder is located inside the roller, and both ends of the central cylinder are provided with flanges located outside the roller. The diameter of the flanges is larger than the diameter of the roller.

[0025] By adopting the above technical solution, since the central cylinder is fixedly connected to the rotating shaft, the structural strength of the rotating shaft is increased to ensure the supporting effect of the rotating shaft on the roller. Furthermore, since both ends of the central cylinder are provided with flanges located outside the roller, and the diameter of the flanges is larger than the diameter of the roller, the flanges can be used to block the movement of the roller in its own axial direction, thereby increasing the connection stability between the roller and the rotating shaft, and thus increasing the stability of the generator roller. At the same time, when the conveyor belt deviates severely or the electric cylinder malfunctions, the flanges can be used to block the conveyor belt to prevent the conveyor belt from continuing to move towards the deviated position.

[0026] Optionally, a bearing is provided between the central cylinder and the roller, with the inner circumferential surface of the bearing contacting the outer circumferential surface of the central cylinder and the outer circumferential surface of the bearing contacting the inner circumferential surface of the roller.

[0027] By adopting the above technical solution, since a bearing is installed between the central shaft and the roller, the central cylinder supports the roller through the bearing, and the friction between the roller and the central cylinder during relative rotation can be reduced, thereby reducing the resistance of the belt when the roller rotates alone, thus reducing the energy consumption of the belt conveyor, and also reducing the noise when the roller rotates relative to the central cylinder.

[0028] Optionally, the rotating shaft is coaxially provided with a central hole, and the wall of the central hole is provided with a wire hole corresponding to the electromagnet, the wire hole extending to the central cylinder.

[0029] By adopting the above technical solution, since the rotating shaft is coaxially provided with a central hole, and the wall of the central hole is provided with a wire hole corresponding to the electromagnet, and the wire hole extends to the central cylinder, the wires used to electrically connect the electromagnet and the battery can be arranged in the wire hole and the wire hole, so as to facilitate the electrical connection between the electromagnet and the battery.

[0030] Optionally, an electric slip ring is provided at the end of the rotating shaft away from the generator, and the electromagnet is electrically connected to the battery through the electric slip ring.

[0031] By adopting the above technical solution, since the electromagnet is electrically connected to the battery through the slip ring, the situation where the wires connecting the battery and the electromagnet will accumulate force around itself during the rotation of the generator roller is avoided. This prevents the wires from easily getting tangled and damaged, and thus ensures the stability of the electrical connection between the electromagnet and the battery.

[0032] Optionally, the belt misalignment switch is located between the belt alignment idler and the power generation idler, and the belt alignment idler, the belt misalignment switch, and the power generation idler are arranged sequentially along the conveying direction of the conveyor belt.

[0033] By adopting the above technical solution, since the alignment idler, the belt misalignment switch, and the generator idler are arranged sequentially along the conveying direction of the belt, the belt first passes through the alignment idler when it moves, and then the belt after being adjusted by the alignment idler passes through the belt misalignment switch. This allows the belt misalignment switch to provide real-time feedback on the belt misalignment based on the alignment effect of the alignment idler, thereby avoiding over-adjustment of the belt and improving the belt alignment effect.

[0034] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0035] 1. The belt alignment device in this application includes a support frame, an alignment assembly, an electric drive assembly, a belt misalignment switch, and a power generation assembly. The alignment assembly includes a roller frame rotatably connected to the support frame and an alignment roller rotatably connected to the roller frame. The electric drive assembly is mounted on the support frame and is used to drive the roller frame to rotate. The belt misalignment switch is mounted on the support frame and located on both sides of the conveyor belt. The power generation assembly includes a power generation roller rotatably connected to the support frame, a generator mounted on the support frame, and a battery mounted on the support frame. The power generation roller supports the conveyor belt and is drively connected to the input shaft of the generator. The generator is electrically connected to the battery, and the battery is electrically connected to... The electric drive assembly and belt misalignment switch ensure that the generator roller remains rotating under the action of the belt during belt movement. This allows the generator to maintain power generation throughout the belt's movement. Compared to existing technologies where the generator only generates power when the belt misaligns, the solution in this application continuously generates power for the battery, preventing potential battery depletion and ensuring battery lifespan. This, in turn, ensures the normal operation of the belt misalignment device and reduces its usage and maintenance costs.

[0036] 2. The electric drive assembly in this application includes an electric cylinder mounted on a support frame and a fixed arm mounted on a roller frame. The piston rod of the electric cylinder is hinged to the end of the fixed arm away from the roller frame. Compared with the prior art scheme of using a hydraulic cylinder to drive the roller frame, this improves the response efficiency of the belt alignment device, thereby improving the belt alignment efficiency.

[0037] 3. The power generation component in this application also includes a gearbox. One end of the power generation roller is driven to the input shaft of the gearbox, and the output shaft of the gearbox is driven to the input shaft of the generator. The rotational speed of the input shaft of the gearbox is less than the rotational speed of the output shaft of the gearbox. This allows the gearbox to increase the rotational speed of the generator input shaft to meet the generator's speed requirements, thereby ensuring the generator's power output and further preventing the battery from experiencing power depletion, thus further ensuring the battery's service life.

[0053] Reference Figures 1 to 7 A belt conveyor alignment device is disclosed, comprising a support frame 1, an alignment component 2, an electric drive component 3, a belt misalignment switch 4, and a power generation component 5. The alignment component 2 includes a roller frame 21 rotatably connected to the support frame 1 and an alignment roller 22 rotatably connected to the roller frame 21. The electric drive component 3 is located on the support frame 1 and is used to drive the roller frame 21 to rotate. The belt misalignment switch 4 is located on the support frame 1 and is situated on both sides of the belt. The power generation component 5 includes a power generation roller 51 rotatably connected to the support frame 1, a generator 52 located on the support frame 1, and a battery 53 located on the support frame 1. The power generation roller 51 is used to support the belt and is drive-connected to the input shaft of the generator 52. The generator 52 is electrically connected to the battery 53, and the battery 53 is electrically connected to the electric drive component 3 and the belt misalignment switch 4.

[0054] It is understood that there are two belt misalignment switches 4, located on both sides of the conveyor belt. The belt misalignment switch 4 is a safety protection device used to detect the belt misalignment of the conveyor belt. It can achieve graded control through a two-stage angle detection mechanism. The first-stage alarm angle range is 10°-20°, triggering an alarm message. The second-stage stop angle is 30°-45°, forcibly cutting off operation. It can automatically reset after the fault is cleared. For the specific structure of the belt misalignment switch 4, please refer to the prior art. The belt misalignment device in this application also includes a PLC controller (programmable logic controller). The battery 53, the belt misalignment switch 4, and the electric drive assembly 3 are all electrically connected to the PLC controller. That is, the battery 53 supplies power to the belt misalignment switch 4 and the electric drive assembly 3 through the PLC controller. When the conveyor belt misaligns and contacts the vertical roller of the belt misalignment switch 4, the belt misalignment switch 4 can send the belt misalignment information to the PLC controller. The PLC controller controls the electric drive assembly 3 to work according to the information sent by the belt misalignment switch 4, so that the electric drive assembly 3 drives the idler frame 21 to the set position.

[0055] When using the belt alignment device in this application, it needs to be installed on the belt conveyor so that the alignment idler 22 and the power generation idler 51 are both located at the bottom of the belt, and the alignment idler 22 and the power generation idler 51 are both in contact with the belt, so that the alignment idler 22 and the power generation idler 51 can support the belt, and the belt deviation switch 4 is located on both sides of the belt.

[0056] When the belt conveyor transports materials, the generator roller 51 is located at the bottom of the belt and in contact with it. This causes the generator roller 51 to rotate under the action of the belt, driving the input shaft of the generator 52 to rotate. The generator 52 then generates electrical energy, which is stored in the battery 53. When the belt deviates from its designated path, one side of the belt contacts the deviation switch 4, causing the deviation switch 4 to send a signal to the PLC controller. The PLC controller then supplies power to the electric drive assembly 3 based on the signal, driving the roller frame 21 to a set position. Under the action of the electric drive assembly 3, the roller frame 21 drives the adjusting roller 22 to rotate relative to the support frame 1, so that the adjusting roller 22 is set at an angle to the conveying direction of the belt. This allows the belt to gradually return to the set position under the action of the adjusting roller 22, thus achieving belt deviation adjustment.

[0057] In this application, the battery 53 is electrically connected to the belt misalignment switch 4 and the electric drive assembly 3 via a PLC controller. This allows the battery 53 to power the belt misalignment switch 4 and the electric drive assembly 3, thus avoiding the need for an additional power supply and reducing the energy consumption of the belt conveyor. Furthermore, since the electric drive assembly 3 drives the idler frame 21 in this application, compared to the prior art which uses a hydraulic cylinder to drive the idler frame 21, the driving efficiency of the idler frame 21 when the belt misaligns is improved. This improves the response efficiency of the belt alignment device when the belt misaligns, thereby increasing the belt alignment efficiency.

[0058] Furthermore, since the generator roller 51 in this application is used to support the conveyor belt, it can maintain rotation under the action of the conveyor belt during the belt's movement. This allows the generator 52 to maintain power generation throughout the belt's movement. Compared to the prior art, where the generator 52 only generates power when the conveyor belt deviates from its designated path, the solution in this application can continuously generate power for the battery 53, preventing potential power depletion and ensuring the battery 53's lifespan. This, in turn, ensures the normal operation of the belt alignment device and reduces the usage and maintenance costs of the belt alignment device.

[0059] To facilitate understanding of the technical solutions in this application, Figure 4To illustrate the belt alignment process, if the conveyor belt deviates to the right, its right side will contact the vertical roller of the belt deviation switch 4 located on the right. The belt deviation switch 4 sends the belt deviation information to the PLC controller. The PLC controller then sends a signal to the electric drive assembly 3 based on the deviation information sent by the belt deviation switch 4. This causes the electric drive assembly 3 to drive the idler frame 21 to rotate clockwise, so that the alignment idler 22 rotates to a set angle less than 90° with the conveying direction of the conveyor belt. At this time, the force on the alignment idler 22 has a component force in its own axial direction, causing the alignment idler 22 to tend to slide along its own axial direction. Since the idler frame 21 can limit the axial movement of the alignment idler 22, the alignment idler 22 applies a reverse force to the conveyor belt, ultimately causing the conveyor belt to gradually return to its original position under the action of the reverse force. Similarly, when the conveyor belt deviates to the left, the electric drive assembly 3 drives the idler frame 21 to rotate counterclockwise.

[0060] This application does not specifically limit the structure of the electric drive assembly 3; preferably, refer to... Figure 1 , Figure 2 , Figure 4 and Figure 5 The electric drive assembly 3 includes an electric cylinder 31 mounted on the support frame 1 and a fixed arm 32 mounted on the roller frame 21. The piston rod of the electric cylinder 31 is hinged to the end of the fixed arm 32 away from the roller frame 21.

[0061] Understandably, the fixed arm 32 is fixedly connected to the roller frame 21.

[0062] When the conveyor belt deviates from its designated path, one side of the belt contacts the deviation switch 4. The deviation switch 4 sends a signal to the electric cylinder 31, causing the piston rod of the electric cylinder 31 to extend or retract according to the signal sent by the deviation switch 4. This causes the piston rod to drive the fixed arm 32 to move, and the fixed arm 32 to drive the idler frame 21 to move, causing the idler frame 21 to rotate relative to the support frame 1. As a result, the idler frame 21 rotates to the set position according to the signal sent by the deviation switch 4. The adjusting idler 22 follows the idler frame 21 to the set position. At this time, the adjusting idler 22 applies resistance to the conveyor belt to continue moving in the deviation direction, so that the conveyor belt deviates towards the correct position under the action of the deviation idler, thereby achieving the adjustment of the conveyor belt.

[0063] In this application, an electric cylinder 31 is used to drive the idler frame 21. Compared with the prior art, which uses a hydraulic cylinder to drive the idler frame 21, this improves the response efficiency of the belt alignment device and thus improves the belt alignment efficiency.

[0064] Specifically, the idler frame 21 has a rotating shaft rotatably connected to the support frame 1. The rotating shaft is vertically arranged. When the piston rod of the electric cylinder 31 extends or retracts, the piston rod pushes or pulls the fixed arm 32 to move, so that the fixed arm 32 drives the idler frame 21 to move, thereby causing the rotating shaft to rotate relative to the support frame 1, so as to realize the adjustment of the idler frame 21.

[0065] This application does not specify the connection method between the electric cylinder 31 and the support frame 1. Preferably, refer to... Figure 2 and Figure 5 The support frame 1 is provided with a hinge seat 11, and the cylinder body of the electric cylinder 31 is hinged to the hinge seat 11. The rotation axis of the electric cylinder 31 is horizontally set to ensure the connection stability between the electric cylinder and the support frame 1. Compared to directly using fasteners to fix the electric cylinder 31 to the support frame 1, this avoids the situation where the connection stability between the cylinder body of the electric cylinder 31 and the support frame 1 is affected by the force exerted on the cylinder body. In other embodiments, fasteners can also be used to fix the cylinder body of the electric cylinder 31 to the support frame 1.

[0066] In other embodiments, the electric drive assembly 3 may also include a servo motor mounted on the support frame 1, a drive gear coaxially fixedly connected to the output shaft of the servo motor, and a driven gear coaxially fixedly connected to the rotating shaft. The drive gear and the driven gear are meshed and connected to drive the roller frame 21 to rotate using the servo motor; or, an electric actuator may be used to replace the electric cylinder 31 in the above embodiments.

[0067] In a preferred embodiment, refer to Figure 1 and Figure 4 The power generation assembly 5 also includes a gearbox 54. One end of the power generation roller 51 is driven to the input shaft of the gearbox 54, and the output shaft of the gearbox 54 is driven to the input shaft of the generator 52. The rotational speed of the input shaft of the gearbox 54 is less than the rotational speed of the output shaft of the gearbox 54.

[0068] Understandably, the generator roller 51 is connected to the input shaft of the generator 52 via a gearbox 54.

[0069] It should be noted that the above-mentioned "the speed of the input shaft of gearbox 54 is less than the speed of the output shaft of gearbox 54" means that when the input shaft of gearbox 54 rotates with the generator roller 51, the speed of the output shaft of gearbox 54 is greater than the speed of the input shaft of gearbox 54, that is, gearbox 54 can increase the speed of the input shaft of generator 52.

[0070] Since one end of the generator roller 51 is driven to the input shaft of the gearbox 54, and the output shaft of the gearbox 54 is driven to the input shaft of the generator 52, and the speed of the input shaft of the gearbox 54 is less than the speed of the output shaft of the gearbox 54, the speed of the input shaft of the generator 52 can be increased by the gearbox 54 to meet the speed requirements of the generator 52, thereby ensuring the power generation of the generator 52 and further preventing the battery 53 from being depleted, thus further ensuring the service life of the battery 53.

[0071] This application does not specifically limit the transmission connection method between the generator roller 51 and the input shaft of the gearbox 54. Preferably, the generator roller 51 is coaxially and fixedly connected to the input shaft of the gearbox 54, that is, the generator roller 51 is welded to the input shaft of the gearbox 54, so as to ensure the connection stability of the generator roller 51 and the input shaft of the gearbox 54 while realizing the transmission connection between them. In other embodiments, the generator roller 51 can also be connected to the input shaft of the gearbox 54 using a coupling.

[0072] This application does not specifically limit the transmission connection method between the output shaft of the gearbox 54 and the input shaft of the generator 52. Preferably, the output shaft of the gearbox 54 is connected to the output shaft of the generator 52 via a coupling to facilitate the transmission connection between the two. In other embodiments, the output shaft of the gearbox 54 may also be fixedly connected to the input shaft of the generator 52 by welding.

[0073] In a preferred embodiment, refer to Figure 6 Both ends of the generator roller 51 are provided with a retaining edge 516. The retaining edge 516 extends along the circumference of the generator roller 51 and is located outside the deviation switch 4.

[0074] It should be noted that the outer side of the deviation switch 4 refers to the side where the two deviation switches 4 are opposite to each other.

[0075] Since both ends of the generator roller are equipped with retaining edges 516, which extend circumferentially along the generator roller 51, the retaining edges 516 can block the conveyor belt when it runs off track or the electric cylinder 31 malfunctions, thereby preventing the conveyor belt from continuing to move toward the off track position.

[0076] Preferably, the opposite end faces of the two side guards 516 are inclined, that is, the opposite end faces of the two side guards 516 are inclined in a direction away from each other along the direction away from the central axis of the generator roller 51.

[0077] This application does not specifically limit the structure of the power generation roller 51, which can adopt any of the following embodiments:

[0078] Implementation Method 1, in this implementation method, refer to Figure 7 The generator roller 51 includes a rotating shaft 511 and a roller 512 sleeved outside the rotating shaft 511. An electromagnet 517 electrically connected to the battery 53 is provided outside the rotating shaft 511. The electromagnet 517 has an energized state and an de-energized state. When the electromagnet 517 is energized, the electromagnet 517 can generate a magnetic attraction force on the roller 512, so that the rotating shaft 511 can rotate with the roller 512 under the action of the electromagnet 517. The rotating shaft 511 is driven to the input shaft of the generator 52.

[0079] It is understood that, in the above embodiment with gearbox 54, one end of the rotating shaft 511 is connected to the input shaft of gearbox 54; the electromagnet 517 is electrically connected to the PLC controller so that the battery 53 supplies power to the electromagnet 517 through the PLC controller.

[0080] After the belt alignment device is installed on the belt conveyor, the belt contacts the roller 512. As the belt moves, the roller 512 rotates under the action of the belt. Simultaneously, the battery 53 supplies power to the electromagnet 517, which in turn energizes the electromagnet 517, generating a magnetic force. This causes the rotating shaft 511 to rotate along with the roller 512 under the magnetic force of the electromagnet 517. The rotating shaft 511 then drives the input shaft of the engine to rotate. The generator 52 generates electricity from the battery 53. As the belt conveyor's operating time increases, the battery 53 stores more and more electricity under the action of the generator 52. After the battery 53 is fully charged, it stops supplying power to the electromagnet 517, and the electromagnet 517 is de-energized. This causes the electromagnet 517 to lose its magnetic attraction to the roller 512, and the rotating shaft 511 can no longer rotate synchronously with the roller 512. This causes the roller 512 to rotate relative to the rotating shaft 511, which in turn causes the input shaft of the generator 52 to be stationary, so that the generator 52 stops generating electricity for the battery 53. This is to avoid the situation where the generator 52 continues to generate electricity for the battery 53, which would affect the service life of the battery 53, and to further ensure the service life of the battery 53.

[0081] Specifically, the PLC controller can monitor the power level of the battery 53. When the PLC controller detects that the power level of the battery 53 is lower than the preset minimum threshold, the battery 53 supplies power to the electromagnet 517 through the PLC controller. The electromagnet 517 generates magnetic attraction, causing the rotating shaft 511 to rotate synchronously with the roller 512 under the action of the electromagnet 517. This causes the rotating shaft 511 to drive the input shaft of the generator 52 to rotate through the gearbox 54, and the generator 52 generates electricity for the battery 53. When the PLC controller detects that the power level of the battery 53 is higher than the maximum threshold, the PLC controller controls the battery 53 to stop supplying power to the electromagnet 517. The electromagnet 517 loses its magnetic attraction, and the rotating shaft 511 can no longer rotate synchronously with the roller 512, so that the generator 52 stops generating electricity for the battery 53.

[0082] Furthermore, refer to Figure 7 The generator roller 51 also includes a central cylinder 513 fixedly connected to the rotating shaft 511. The central cylinder 513 is located inside the roller 512, and both ends of the central cylinder 513 are provided with side flanges 516 located outside the roller 512. The diameter of the side flanges 516 is larger than the diameter of the roller 512.

[0083] It is understandable that the electromagnet 517 is fixedly connected to the outer circumferential surface of the central cylinder 513.

[0084] Since the central cylinder 513 is fixedly connected to the rotating shaft 511, the structural strength of the rotating shaft 511 is increased to ensure the supporting effect of the rotating shaft 511 on the roller 512. Furthermore, since both ends of the central cylinder 513 are provided with flanges 516 located outside the roller 512, and the diameter of the flanges 516 is larger than the diameter of the roller 512, the flanges 516 can be used to block the movement of the roller 512 in its own axial direction, thereby increasing the connection stability between the roller 512 and the rotating shaft 511, and thus increasing the stability of the generator roller 51. At the same time, when the conveyor belt deviates severely or the electric cylinder 31 malfunctions, the flanges 516 can be used to block the conveyor belt to prevent the conveyor belt from continuing to move towards the deviated position.

[0085] Furthermore, refer to Figure 7 A bearing is provided between the center cylinder 513 and the roller 512. The inner circumferential surface of the bearing contacts the outer circumferential surface of the center cylinder 513, and the outer circumferential surface of the bearing contacts the inner circumferential surface of the roller 512. This allows the center cylinder 513 to support the roller 512 through the bearing, and also reduces the friction between the roller 512 and the center cylinder 513 when they rotate relative to each other. This reduces the resistance experienced by the belt when the roller 512 rotates alone, thereby reducing the energy consumption of the belt conveyor. It also reduces the noise when the roller 512 rotates relative to the center cylinder 513.

[0086] The better one is to refer to Figure 7 At least two bearings are provided at intervals between the center cylinder 513 and the roller 512, with the two bearings located at both ends of the roller 512, to increase the stability of the roller 512.

[0087] Preferably, bearings are also fitted at both ends of the rotating shaft 511, and the support frame 1 is provided with bearing seats located outside the two bearings, so as to realize the rotational connection between the rotating shaft 511 and the support frame 1, and at the same time reduce the resistance when the rotating shaft 511 rotates.

[0088] Furthermore, refer to Figure 7 The rotating shaft 511 is coaxially provided with a central hole 514, and the wall of the central hole 514 is provided with a wire hole 515 corresponding to the electromagnet 517. The wire hole 515 extends to the central cylinder 513.

[0089] It is understandable that the electromagnet 517 is electrically connected to the PLC controller via a wire, which passes through the central hole 514 and is connected to the electromagnet 517 via the wire hole 515.

[0090] Since the rotating shaft 511 is coaxially provided with a central hole 514, and the wall of the central hole 514 is provided with a wire hole 515 corresponding to the electromagnet 517, and the wire hole 515 extends to the central cylinder 513, the wires used for electrically connecting the electromagnet 517 and the PLC controller can be arranged in the wire hole 515 and the wire hole 515, so as to facilitate the electrical connection between the electromagnet 517 and the PLC controller.

[0091] Preferably, an electric slip ring is provided at the end of the rotating shaft 511 away from the generator 52. The electromagnet 517 is electrically connected to the battery 53 through the electric slip ring. That is, the wire used to electrically connect the electromagnet 517 and the PLC controller is divided into two sections. One end of the two sections of wire is connected to the input and output ends of the electric slip ring, respectively, and the other end of the two sections of wire is connected to the electromagnet 517 and the PLC controller, respectively. This avoids the situation where the wire connecting the battery 53 and the electromagnet 517 will accumulate force around itself during the rotation of the generator roller 51, thereby avoiding the situation where the wire is easily tangled and damaged, and thus ensuring the stability of the electrical connection between the electromagnet 517 and the battery 53.

[0092] Implementation Method Two: In this implementation method, refer to... Figure 1 , Figure 3 , Figure 4 and Figure 6 The generator roller 51 is an integral structure, that is, the generator roller 51 includes a roller body and connecting shafts located at both ends of the roller body. One end of the connecting shaft is connected to the input shaft of the gearbox 54 to reduce the manufacturing difficulty of the generator roller 51 and reduce the manufacturing cost of the alignment device.

[0093] This application does not specifically limit the position of the belt misalignment switch 4, the adjusting roller 22, and the generator roller 51. Preferably, the belt misalignment switch 4 is located between the adjusting roller 22 and the generator roller 51, and the adjusting roller 22, the belt misalignment switch 4, and the generator roller 51 are arranged sequentially along the conveying direction of the belt. This allows the belt to pass through the adjusting roller 22 first, and then pass through the belt misalignment switch 4 after being adjusted by the adjusting roller 22. This enables the belt misalignment switch to provide real-time feedback on the belt misalignment based on the adjustment effect of the adjusting roller 22, thereby avoiding over-adjustment of the belt and improving the belt misalignment effect.

[0094] In other embodiments, the generator roller 51, the alignment roller 22, and the belt misalignment switch 4 may be arranged sequentially along the conveying direction of the belt; or, the belt misalignment switch 4 may be located on the side of the alignment roller 22 away from the generator roller 51.

[0095] This application does not specifically limit the structure of the alignment roller 22. The conveyor belt has a ring structure and can be divided into a conveying section for transporting materials and a rotating section for returning to its original position after transporting. The cross-sectional shape of the conveying section is usually trough-shaped, while the cross-sectional shape of the rotating section is usually straight. Therefore, the alignment device can be divided into a conveying section alignment device for adjusting the conveying section and a rotating section alignment device for adjusting the rotating section. (Refer to...) Figure 1 and Figure 2 For the conveyor section alignment device, it may include multiple alignment rollers 22, each with a length less than the width of the conveyor belt. These rollers are rotatably connected to the roller frame 21 and together form a trough-shaped structure to improve the alignment effect on the conveyor section. (Refer to...) Figure 4 and Figure 5 For the slewing section alignment device, only one alignment roller 22 can be set, and the length of the alignment roller 22 is greater than the width of the conveyor belt, so as to improve the alignment effect of the slewing section.

[0096] Furthermore, refer to Figure 1 and Figure 3 For the conveyor section alignment device, it may also include auxiliary idlers 6. There are two auxiliary idlers 6, which are located on both sides of the conveyor section respectively. Each auxiliary idler 6 is inclined and adapted to the shape of both sides of the conveyor section. Each auxiliary idler 6 is rotatably connected to the support frame 1 to improve the support effect on the conveyor belt, thereby ensuring the conveying efficiency of the conveyor belt for materials.

[0097] Preferably, the ends of the two auxiliary rollers 6 that are far apart from each other are also provided with guards 516, so that when the conveyor belt runs off track seriously or the electric cylinder 31 malfunctions, the guards 516 provided on the auxiliary rollers 6 can be used to block the conveyor belt, thereby preventing the conveyor belt from continuing to move toward the off track position.
