A deviation correction mechanism and method for a belt conveyor

Abstract

The application provides a deviation rectifying mechanism and method of a belt conveyor, and relates to the technical field of belt conveyors, which comprises a mounting plate, a conveying belt, a truss and a deviation rectifying assembly. Two side plates are fixed to the outer wall of the mounting plate, positioning plates are fixed to the two sides of the mounting plate and outside the two side plates, and a first rotating plate and a second rotating plate are respectively rotatably connected to the upper surfaces of the two side plates. Two deviation rectifying modes are provided in the application. The first mode is to use conical first and second deviation rectifying rollers. The conical surface can ensure a larger contact surface of the conveying belt, thereby ensuring a larger deviation rectifying force. The second mode is to control the mutual folding of the bending plate and the connecting plate to generate a larger inclined surface for limiting the conveying belt when the conveying belt deviates to the position of the bending plate, so that the conveying belt can move within a predetermined deviation rectifying range, and the deviation rectifying force can be increased with the increase of the deviation force.

Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and more particularly to a belt conveyor correction mechanism and method. Background Technology

[0002] A belt conveyor is a continuous conveying machine that uses a flexible conveyor belt as the material carrying and traction component. An endless conveyor belt wraps around a drive drum and guide drums, and the upper and lower branches between the drive drum and guide drums are each supported by several idlers. The material is placed on the upper branch, and the friction between the drive drum and the belt pulls the conveyor belt and the material.

[0003] In mining and tunneling processes, belt conveyors are widely used for material transport. When belt conveyors operate for extended periods, uneven material distribution can cause the belt to deviate from the rollers and idlers. This deviation can lead to friction between the belt edge and the frame, which can easily cause belt damage, reduce belt lifespan, and affect equipment operation.

[0004] Announcement No.: CN217946626U discloses a belt alignment device and a belt conveyor. The belt alignment device is mounted on a belt conveyor, which has a frame. A drive roller and a guide roller are mounted on the frame. The belt is wound around the drive roller and the guide roller, and idlers supporting the belt are mounted on the frame. The device includes a first alignment mechanism and a second alignment mechanism, mounted on the frame. The first and second alignment mechanisms are used to correct belt alignment during the conveying and return processes, respectively. By setting the first and second alignment mechanisms, belt alignment can be achieved during both the conveying and return processes. Both mechanisms can adjust their relative positions to the frame, adapting to different belt alignment requirements.

[0005] However, in actual use, the above-mentioned devices are mostly used in mining. In harsh environments (dust, humidity, high temperature), the hydraulic / pneumatic or automatic correction system is prone to failure. The sensors may be interfered with. Secondly, the correction rollers of the above-mentioned devices are straight rollers. This greatly limits the contact area between the conveyor belt and the correction rollers during the rotation correction process, which will waste the power generated by correction. In fact, derailment may even occur when the deviation is large.

[0006] Therefore, it is necessary to provide a belt conveyor correction mechanism and method to solve the above-mentioned technical problems. Summary of the Invention

[0007] This invention provides a belt conveyor correction mechanism and method, which solves the technical problems of poor environmental adaptability and poor correction effect of straight correction rollers in the existing correction mechanism.

The correction assembly includes a base plate, a top plate is bolted to the bottom of the base plate, a positioning seat is fixed at the center of the top of the top plate, a receiving roller is rotatably connected inside the positioning seat, a first mounting seat and a second mounting seat are fixed on the upper surface of the top plate and on both sides of the positioning seat respectively, a first bracket is rotatably connected inside the first mounting seat, a first correction roller is rotatably connected inside the first bracket, a second bracket is rotatably connected inside the second mounting seat, and a second correction roller is rotatably connected inside the second bracket. The bottom of the base plate and the two sides of the center seat are rotatably connected to a linkage plate. The correction assembly also includes two sliding plates. The outer wall of the sliding plates is equidistantly connected to a curved plate around the axis. The curved plate has a slot inside. The top axis of the first correction roller and the second correction roller are both fixed with a central shaft. The top of the two central shafts are both fixed with a turntable. The outer wall of the turntable is equidistantly connected to a connecting plate around the axis.

[0009] Preferably, the first trigger roller and the second trigger roller are inclined in opposite directions, the cross-section of the first rotating plate and the second rotating plate are both "L" shaped, and the bottom of the two linkage plates are rotatably connected to the upper surface of the first rotating plate and the second rotating plate.

[0010] Preferably, the bottom center of the base plate and the top center of the center seat are rotatably connected, and the first and second correction rollers are two identical tapered structures that are narrow at the bottom and wide at the top.

[0011] Preferably, the axis of the turntable is rotatably connected to the top of the first support and the second support, and the slide plate and the central shaft are slidably connected.

[0012] Preferably, it also includes an adjustment assembly, which includes a dual-head motor installed in the interlayer between the bottom plate and the top plate. The dual-head motor has a positive and negative screw installed inside. The outer wall of the positive and negative screw is threaded with two sliders. The top of each slider is rotatably connected to a connecting plate. The bottom of the first bracket and the second bracket are both fixed with connecting seats.

[0013] Preferably, both sides of the positive and negative screws are rotatably connected to the interlayer of the bottom plate and the top plate via bearings, and the tops of the two connecting plates are rotatably connected to the two connecting seats.

[0014] Preferably, it also includes an auxiliary component, which includes a gear rotatably connected inside the center seat, two racks meshing on both sides of the gear, a top block fixed at the front end of each of the two racks, two limiting frames fixed on the outer wall of the mounting plate, a lifting plate slidably connected inside the two limiting frames and above the two top blocks, and an auxiliary roller rotatably connected to the top of each of the two lifting plates.

[0015] Preferably, the shaft of the gear is connected to the bottom keyway of the base plate, and the outer walls of the two top blocks and the bottoms of the two lifting plates are all constructed with a 45-degree slope and fit together.

[0016] A method for using a belt conveyor's correction mechanism includes the following steps: S1: Preparations before installation Stop the machine and disconnect the power supply, hang warning signs, and implement the "lock and tag" procedure. Clean up coal gangue and debris on the conveyor belt and truss. The entire correction mechanism needs to be installed at the left or right end of the truss (the specific location depends on the site environment, but it is often chosen near the starting point of the deviation, such as behind the drive roller or the redirecting roller). S2: Installation; Two positioning plates are mounted on the truss, and the mounting plates are fastened to the truss with bolts to ensure that the mounting plates are level with the truss. Secondly, the first correction roller, the second correction roller and the receiving roller can preferably be made of rubber material. S3: Correcting deviations during work; When the conveyor belt deviates to the left, the left side of the conveyor belt will be subjected to the force of the first trigger roller. When the first vertical plate and the first rotating plate are subjected to the left deviation force, they will rotate clockwise, causing the linkage plate to pull the bottom plate and top plate in the installation state to rotate counterclockwise. When rotating counterclockwise, the rotational thrust generated by the counterclockwise rotation of the first correction roller will push the left-deviated conveyor belt to the right, and straighten the conveyor belt to the right. When the conveyor belt deviates to the right, the right side of the conveyor belt will be subjected to the force of the second trigger roller. When the second vertical plate and the second rotating plate are subjected to the rightward deviation force, they will rotate counterclockwise, causing the linkage plate to pull the bottom plate and top plate in the installation state to rotate clockwise. When rotating clockwise, the rotational thrust generated by the clockwise rotation of the second correction roller will push the rightward deviated conveyor belt to the left, and straighten the conveyor belt to the left.

[0017] Compared with related technologies, the belt conveyor correction mechanism and method provided by the present invention have the following beneficial effects: Compared to traditional belt alignment component designs, this design improves the belt alignment method by employing a multi-plate connection. When the conveyor belt deviates to the left or right, the first and second trigger rollers immediately trigger the "V"-shaped first and second alignment rollers to rotate to the left or right, applying rotational force to correct the deviated conveyor belt. This method ensures precise alignment. Furthermore, the purely mechanical linkage ensures normal operation even in harsh mining environments, eliminating concerns about environmental factors affecting electronic sensors. In addition, compared to traditional alignment designs, this design incorporates two alignment methods. The first uses conical first and second alignment rollers, whose conical surfaces ensure a larger contact area with the conveyor belt, resulting in a stronger alignment force. The second method, as the conveyor belt deviates further, triggers a bending plate when it reaches the bending plate, causing the bending plate and connecting plate to fold and bend against each other, creating a larger slope to restrict the conveyor belt's movement within a predetermined alignment range. The alignment force increases with the degree of deviation. Attached Figure Description

[0021] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] This invention provides a belt conveyor correction mechanism and method.

[0024] First embodiment: Please see Figures 1 to 5A belt conveyor correction mechanism includes a mounting plate 1, a conveyor belt 15, a truss 16, and a correction assembly 6. Two side plates 2 are fixedly provided on the outer wall of the mounting plate 1. Positioning plates 9 are fixedly provided on both sides of the mounting plate 1 and on the outer sides of the two side plates 2. A first rotating plate 3 and a second rotating plate 10 are rotatably connected to the upper surfaces of the two side plates 2, respectively. A first upright plate 4 is bolted to the upper surface of the first rotating plate 3. A first trigger roller 5 is obliquely rotatably connected to the top of the first upright plate 4. A second upright plate 11 is bolted to the upper surface of the second rotating plate 10. A second trigger roller 12 is obliquely rotatably connected to the top of the second upright plate 11. A center seat 14 is fixedly provided at the center of the upper surface of the mounting plate 1. The correction assembly 6 includes a base plate 61. A top plate 62 is bolted to the bottom of the base plate 61. A positioning seat 63 is fixedly provided at the center of the top of the top plate 62. A receiving roller 64 is rotatably connected inside the positioning seat 63. A first mounting seat 65 and a second mounting seat 68 are fixedly provided on the upper surface of the top plate 62 and on both sides of the positioning seat 63. A first bracket 66 is rotatably connected inside the first mounting seat 65. A first correction roller 67 is rotatably connected inside the first bracket 66. A second bracket 69 is rotatably connected inside the second mounting seat 68. A second correction roller 610 is rotatably connected inside the second bracket 69. The bottom of the base plate 61 and the two sides of the center seat 14 are rotatably connected to the linkage plate 13. Please see Figure 2 and Figure 4 When the conveyor belt 15 (the mining conveyor belt 15 is generally a V-belt) passes through the correction mechanism, the left and right sides of the conveyor belt 15 need to be attached to the outer walls of the first correction roller 67 and the second correction roller 610, and the first trigger roller 5 and the second trigger roller 12 relatively restrict the two sides of the conveyor belt 15. Once the conveyor belt 15 deviates to the left, the left side of the conveyor belt 15 will be subjected to the force of the first trigger roller 5. When the first vertical plate 4 and the first rotating plate 3 are subjected to the leftward deviation force, they will rotate clockwise, causing the linkage plate 13 to pull the bottom plate 61 and the top plate 62 in the installation state to rotate counterclockwise. When rotating counterclockwise, the rotational thrust generated by the counterclockwise rotation of the first correction roller 67 will push the leftward deviated conveyor belt 15 to the right, and straighten the conveyor belt 15 to the right.

[0025] Please see Figure 3If the conveyor belt 15 deviates to the right, the right side of the conveyor belt 15 will be subjected to the force of the second trigger roller 12. When the second vertical plate 11 and the second rotating plate 10 are subjected to the rightward deviation force, they will rotate counterclockwise, causing the linkage plate 13 to pull the bottom plate 61 and the top plate 62 in the installation state to rotate clockwise. When rotating clockwise, the rotational thrust generated by the clockwise rotation of the second correction roller 610 will push the rightward deviated conveyor belt 15 to the left, and straighten the conveyor belt 15 to the left.

[0026] Please see Figure 4 The bottom of the conveyor belt 15 after the final return to center needs to be attached to the receiving roller 64.

[0027] The correction assembly 6 also includes two sliding plates 611. The outer wall of the sliding plates 611 is equidistantly connected to a curved plate 612 around its axis. The curved plate 612 has a slot 613 inside. The top axis of the first correction roller 67 and the second correction roller 610 are both fixed with a central shaft 615. The top of the two central shafts 615 are both fixed with a turntable 614. The outer wall of the turntable 614 is equidistantly connected to a connecting plate 616 around its axis.

[0028] Please see Figure 2 and Figure 3 Regardless of whether the conveyor belt 15 shifts to the left or right, the side of the conveyor belt 15 is always attached to the first correcting roller 67 or the second correcting roller 610. The greater the offset of the conveyor belt 15, the higher the contact surface between the side of the conveyor belt 15 and the first and second straightening rollers 67 and 610 will be. When moving upward, the edge of the conveyor belt 15 will contact the bending plate 612. During the process of applying force to the bending plate 612, the slide plate 611 will be driven to rise along the central axis 615. During the rising process, the bending plate 612 and the connecting plate 616 fold and bend each other, changing the bending angle. The angle of the bending plate 612 is large, which can effectively limit the large deviation of the conveyor belt 15.

[0029] The first trigger roller 5 and the second trigger roller 12 are inclined in opposite directions. The cross-section of the first rotating plate 3 and the second rotating plate 10 is "L" shaped. The bottom of the two linkage plates 13 is rotatably connected to the upper surface of the first rotating plate 3 and the second rotating plate 10.

[0030] The bottom center of the base plate 61 is rotatably connected to the top center of the center seat 14, and the first correction roller 67 and the second correction roller 610 are two identical tapered structures that are narrow at the bottom and wide at the top.

[0031] The turntable 614 is rotatably connected to the top of the first bracket 66 and the second bracket 69 at its axis, and the slide plate 611 and the central shaft 615 are slidably connected.

[0032] Please see Figure 5 It is understandable that the slots 613 inside each bending plate 612 and each connecting plate 616 are adapted to each other. When the bending plate 612 and the connecting plate 616 are bent and folded, the slots 613 can ensure that the connecting plate 616 can pass smoothly and avoid interference. Secondly, the turntable 614, the central shaft 615, the first correction roller 67, and the second correction roller 610 are integrated into one unit, which ensures that the bending plate 612 and the connecting plate 616 can still rotate during the lifting process.

[0033] This embodiment, compared to the traditional correction component 6 design, improves the correction method by employing a multi-plate connection. When the conveyor belt 15 shifts to the left or right, the first trigger roller 5 and the second trigger roller 12 will immediately trigger the "V"-shaped first correction roller 67 and second correction roller 610 to rotate to the left or right, applying rotational force to correct the shifted conveyor belt 15. This working method ensures precise correction. Furthermore, the purely mechanical linkage ensures normal operation even in harsh mining environments, eliminating the need to consider the impact of environmental factors on electronic sensors. Compared to traditional correction designs, this design incorporates two correction methods. The first method uses a conical first correction roller 67 and a second correction roller 610. The conical surface ensures a larger contact area for the conveyor belt 15, resulting in a stronger correction force. The second method involves controlling the bending plate 612 and connecting plate 616 to fold and bend against each other as the conveyor belt 15 deviates further. This creates a larger inclination surface that restricts the conveyor belt 15, ensuring it can move within a predetermined correction range. Furthermore, the correction force increases with the increase in deviation force.

[0034] Second embodiment: Please see Figure 7 and Figure 8 It also includes an adjustment component 7, which includes a dual-head motor 71 installed in the interlayer between the base plate 61 and the top plate 62. The dual-head motor 71 has a positive and negative screw 72 installed inside. The outer wall of the positive and negative screw 72 is threadedly connected to two sliders 73. The top of each slider 73 is rotatably connected to a connecting plate 74. The bottom of the first bracket 66 and the second bracket 69 are both fixed with a connecting seat 75.

[0035] Both sides of the positive and negative screws 72 are rotatably connected to the interlayer of the bottom plate 61 and the top plate 62 via bearings, and the tops of the two connecting plates 74 are rotatably connected to the two connecting seats 75.

[0036] Please see Figure 7 and Figure 8The dual-head motor 71 can be started to control the forward and reverse rotation of the screw 72. During the rotation of the screw 72, the two sliders 73 can move relative to each other or move apart. If the two sliders 73 move relative to each other, they will control the two connecting plates 74 to change from an inclined state to an upright state. During the movement, they will control the connecting seat 75 to move the first bracket 66 and the second bracket 69 to change their relative angles synchronously. If the two sliders 73 move apart, they will control the two connecting plates 74 to change from an inclined state to a more inclined state. During the movement, the connecting seat 75 will be pulled to drive the first bracket 66 and the second bracket 69 to change their angles and move apart synchronously.

[0037] Combination Figure 8 It can be seen that the dual-head motor 71 is installed inside the base plate 61 and the top plate 62, which can ensure the sealing.

[0038] In this embodiment, the user can change the specifications of the first correction roller 67 and the second correction roller 610 according to different specifications of conveyor belts 15. The rotating positive and negative screws 72 can control the relative or disjoint movement of the slider 73. When moving relative to each other, the first support 66 and the second support 69 can rotate relative to each other, thus reducing the angle formed with the top plate 62, which is suitable for smaller conveyor belts 15. When moving disjointly, the first support 66 and the second support 69 can rotate apart, thus increasing the angle formed with the top plate 62, which is suitable for larger conveyor belts 15. This design can be directly adjusted on the mounting plate 1 after installation, and can be used to correct the deviation of conveyor belts 15 of different sizes, achieving stronger compatibility and avoiding repeated replacement and installation.

[0039] Third embodiment: Please see Figure 2 , Figure 3 , Figures 9 to 11 It also includes an auxiliary component 8, which includes a gear 17 rotatably connected inside the center seat 14. Two racks 81 are meshed on both sides of the gear 17. A top block 83 is fixed at the front end of each of the two racks 81. Two limiting frames 82 are fixed on the outer wall of the mounting plate 1. A lifting plate 84 is slidably connected inside the two limiting frames 82 and above the two top blocks 83. An auxiliary roller 85 is rotatably connected to the top of each of the two lifting plates 84.

[0040] The shaft of the gear 17 is connected to the bottom keyway of the base plate 61. The outer walls of the two top blocks 83 and the bottoms of the two lifting plates 84 are both constructed with a 45-degree slope and fit together.

[0041] Please see Figure 2 , Figure 9 and Figure 10 In the working state of the first embodiment, when the base plate 61 rotates counterclockwise, it will synchronously drive the gear 17 to rotate. The rotating gear 17 will control the two racks 81 to move relative to each other. One of the racks 81 will control the top block 83 to move forward through the inclined plane and control the inclined plane at the bottom of the lifting plate 84, so that the lifting plate 84 can drive the auxiliary roller 85 to rise.

[0042] Please see Figure 3 , Figure 9 and Figure 10 If the base plate 61 rotates clockwise, it will synchronously drive the gear 17 to rotate. The rotating gear 17 will control the two racks 81 to move relative to each other. One of the racks 81 will control the top block 83 to move forward and control the inclined plane at the bottom of the lifting plate 84 through the inclined plane force, so that the lifting plate 84 can drive the auxiliary roller 85 to rise. Therefore, regardless of whether the conveyor belt 15 is shifted to the left or to the right, in the first embodiment's correction state, it can also be assisted by the rise of the auxiliary roller 85.

[0043] Combination Figure 11 It can be seen that the bottom of the two racks 81 and the mounting plate 1 are slidably installed, which can ensure that the racks 81 can slide stably and prevent the racks 81 from derailing.

[0044] In this embodiment, compared to traditional correction designs, there are two racks 81 that move in conjunction with the first correction roller 67 and the second correction roller 610. Regardless of whether the conveyor belt 15 deviates to the left or to the right, at least one rack 81 can be guaranteed to move forward. The forward movement of the rack 81 can control the auxiliary roller 85 to rise and push the bottom surface of the conveyor belt 15, adding an upward pushing force on the basis of the rotational correction force. This can assist in correction and ensure that the conveyor belt 15 can quickly return to the correct position. At the same time, it can also effectively eliminate the tension of the conveyor belt 15 during the conveying process, ensuring that the tension of the conveyor belt 15 is tighter.

[0045] Please refer to the reference again. Figures 1 to 11 The working principle of the belt conveyor correction mechanism provided by this invention is as follows: In step S1, when the conveyor belt 15 (a mining conveyor belt 15 is generally a V-belt) passes through the correction mechanism, the left and right sides of the conveyor belt 15 need to be against the outer walls of the first correction roller 67 and the second correction roller 610. The first trigger roller 5 and the second trigger roller 12 relatively restrict the two sides of the conveyor belt 15. Once the conveyor belt 15 shifts to the left, the left side of the conveyor belt 15 will be subjected to force from the first trigger roller 5. When the first vertical plate 4 and the first rotating plate 3 are subjected to the leftward shifting force, they will rotate clockwise, causing the linkage plate 13 to pull the bottom plate 61 and the top plate 62 in the installed state to rotate counterclockwise. When the conveyor belt 15 shifts to the right by the counterclockwise rotation of the first correction roller 67, the right side of the conveyor belt 15 will be pushed by the rotational thrust generated by the counterclockwise rotation of the first correction roller 67, and the conveyor belt 15 will be returned to the right. When the conveyor belt 15 shifts to the right, the right side of the conveyor belt 15 will be subjected to the force of the second trigger roller 12. When the second vertical plate 11 and the second rotating plate 10 are subjected to the rightward shifting force, they will rotate counterclockwise, causing the linkage plate 13 to pull the bottom plate 61 and the top plate 62 in the installation state to rotate clockwise. When rotating clockwise, the rotational thrust generated by the clockwise rotation of the second correction roller 610 will push the conveyor belt 15 shifted to the left, and the conveyor belt 15 will be returned to the left. The greater the offset of the conveyor belt 15, the higher the contact surface between the side of the conveyor belt 15 and the first and second straightening rollers 67 and 610 will be. When moving upward, the edge of the conveyor belt 15 will contact the bending plate 612. During the process of applying force to the bending plate 612, the slide plate 611 will be driven to rise along the central axis 615. During the rising process, the bending plate 612 and the connecting plate 616 fold and bend each other, changing the bending angle. The bending plate 612 has a large angle, which can effectively limit the large deviation of the conveyor belt 15. In step S2, during the actual process, the user can change the angle of the first straightening roller 67 and the second straightening roller 610 according to the different specifications of the conveyor belt 15. The rotating positive and negative screws 72 can control the relative or disjoint movement of the slider 73. When moving relative to each other, the first support 66 and the second support 69 can rotate relative to each other, so that the angle formed with the top plate 62 becomes smaller, which can be used for small-sized conveyor belts 15. When moving apart, the first support 66 and the second support 69 can rotate apart, so that the angle formed with the top plate 62 becomes larger, which can be used for larger-sized conveyor belts 15.

[0046] In step S3, when the base plate 61 rotates counterclockwise, it will synchronously drive the gear 17 to rotate. The rotating gear 17 will control the two racks 81 to move relative to each other. One of the racks 81 will control the top block 83 to move forward and control the inclined plane at the bottom of the lifting plate 84 through the inclined plane force, so that the lifting plate 84 can drive the auxiliary roller 85 to rise. When the base plate 61 rotates clockwise, it will synchronously drive the gear 17 to rotate. The rotating gear 17 will control the two racks 81 to move relative to each other. One of the racks 81 will control the top block 83 to move forward and pass through the inclined plane to control the inclined plane at the bottom of the lifting plate 84, so that the lifting plate 84 can drive the auxiliary roller 85 to rise.

[0047] Please refer to the reference again. Figures 1 to 11 A method for using a belt conveyor's correction mechanism includes the following steps: S1: Preparations before installation Stop the machine and disconnect the power supply, hang a warning sign, and perform "lock and tag". Clean the coal gangue and debris on the conveyor belt 15 and truss 16. The entire correction mechanism needs to be installed at the left or right end of the truss 16 (the specific situation depends on the site environment, but it is often chosen near the starting point of the deviation, such as behind the drive roller or the redirecting roller). S2: Installation; Two positioning plates 9 are mounted on the truss 16, and the mounting plate 1 is fastened to the truss 16 with bolts to ensure that the mounting plate 1 is horizontal to the truss 16. Secondly, the first correction roller 67, the second correction roller 610 and the receiving roller 64 can preferably be made of rubber material. S3: Correcting deviations during work; When the conveyor belt 15 deviates to the left, the left side of the conveyor belt 15 will be subjected to the force of the first trigger roller 5. When the first vertical plate 4 and the first rotating plate 3 are subjected to the left deviation force, they will rotate clockwise, causing the linkage plate 13 to pull the bottom plate 61 and the top plate 62 in the installation state to rotate counterclockwise. When rotating counterclockwise, the rotational thrust generated by the counterclockwise rotation of the first correction roller 67 will push the left-deviated conveyor belt 15 to the right, and return the conveyor belt 15 to the right. When the conveyor belt 15 deviates to the right, the right side of the conveyor belt 15 will be subjected to the force of the second trigger roller 12. When the second vertical plate 11 and the second rotating plate 10 are subjected to the rightward deviation force, they will rotate counterclockwise, causing the linkage plate 13 to pull the bottom plate 61 and the top plate 62 in the installation state to rotate clockwise. When rotating clockwise, the rotational thrust generated by the clockwise rotation of the second correction roller 610 will push the rightward deviated conveyor belt 15 to the left, and straighten the conveyor belt 15 to the left.
