Description

Technical Field

[0001] This invention relates to the field of conveyor technology, specifically to an intelligent belt conveyor with a correction mechanism. Background Technology

[0002] Traditional belt conveyors often experience deviation due to factors such as uneven material loading, roller wear, and uneven belt tension. Furthermore, they rely heavily on manual observation and adjustment, resulting in three major drawbacks: delayed correction, over-correction, and belt damage. The correction and maintenance of traditional belt conveyors require manual intervention, leading to high labor intensity, low efficiency, and significant errors. Additionally, the fixed support structure of traditional conveyors cannot accommodate conveyor belts of different widths. Moreover, the asynchronous rotation of the support rollers in traditional conveyors results in high friction and rapid wear. Therefore, we have introduced an intelligent belt conveyor with corrective deviation. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent belt conveyor for correcting deviations, in order to solve the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An intelligent belt conveyor with a correction mechanism includes a conveyor frame and a control console. The upper end of the conveyor frame is provided with mounting plates at equal intervals. The upper end of the middle part of the mounting plates is provided with an intermediate support roller assembly, side support roller assemblies that are driven to both sides of the intermediate support roller assembly, and side bracket roller assemblies that are driven to the end of the side support roller assembly.

[0006] A drive motor is installed at the lower middle part of the mounting plate;

[0007] Several sets of position sensors are evenly spaced on both sides of the upper end of the conveyor frame. When the position sensors detect that the conveyor belt on the conveyor frame is deviating, the control console controls the drive motor to work. The drive motor drives the side support roller assembly to adjust the tilt angle of the side bracket roller assembly through the side support roller assembly, so that the side bracket roller assembly contacts the conveyor belt and corrects the conveyor belt deviation. At the same time, the side support roller assembly also lubricates the side rollers of the side bracket roller assembly through the lubrication assembly on the mounting plate.

[0008] Preferably, the top two ends of the conveyor frame are respectively provided with a driving roller and a driven roller for driving the conveyor belt.

[0009] Preferably, the intermediate support roller assembly includes an intermediate U-shaped seat fixed to the middle of the upper end of the mounting plate, an intermediate support roller movably connected within the intermediate U-shaped seat, and a square transmission arm fixed to the middle of the intermediate support roller.

[0010] Preferably, a first bearing cylinder is fixed to the outer side wall of the intermediate U-shaped seat, a first bearing is provided inside the first bearing cylinder, a first rotating shaft is provided in the middle of the intermediate support roller, and the first bearing is sleeved on the first rotating shaft.

[0011] Preferably, the side support roller assembly includes a side U-shaped seat slidably mounted on the mounting plate and a side support roller movably connected within the side U-shaped seat;

A second rotating shaft is provided in the middle of the side support roller, and the second bearing is sleeved on the second rotating shaft.

[0013] The second rotating shaft has a first square through slot in the middle for inserting a square transmission arm.

[0014] The mounting plate has a limiting sliding groove in the middle, and a limiting slider that slides in the limiting sliding groove is located at the lower middle of the side U-shaped seat. A rack is provided on the side of the limiting slider, and the gear at the upper end of the drive motor meshes between the racks distributed in front and behind.

[0015] Preferably, the side support roller assembly includes a U-shaped support movably connected to the upper end of the conveyor frame and a lubricating oil open box fixed in the middle of the upper end of the U-shaped support;

[0016] The upper end of the conveyor frame is provided with an L-shaped frame, and the L-shaped frame is provided with an inclined groove. The two ends of the support rod at the middle of the lower end of the U-shaped bracket are slidably connected to the inclined groove.

[0017] The side roller is movably connected to the U-shaped bracket, and the bottom of the side roller is located inside the open lubricating oil box;

[0018] The side rollers and the corresponding second rotating shafts are connected by a universal joint transmission assembly.

[0019] Preferably, a piston is fixed to the end of the extension rod in the middle of the side of the U-shaped seat;

[0020] The lubrication assembly includes a pneumatic cylinder body fixed to a mounting plate, lubricating oil tanks located on both sides of the pneumatic cylinder body, an air pipe connecting the side of the pneumatic cylinder body and the upper part of the lubricating oil tank, and a hose connecting the bottom of the lubricating oil tank and the inside of the lubricating oil open box.

[0021] The piston is slidably connected to the pneumatic cylinder body;

[0022] The inner wall of the open lubricating oil box is equipped with a brush.

[0023] Preferably, a third rotating shaft is provided in the middle of the side roller, a third bearing cylinder is fixed at the upper end of the U-shaped bracket, and a third bearing sleeved on the third rotating shaft is provided inside the third bearing cylinder;

[0024] The universal joint drive assembly includes a first universal joint fixed to the inner end of a corresponding third rotating shaft, a second universal joint fixed to the end of a corresponding second rotating shaft, and a cross shaft connecting the first universal joint and the second universal joint.

[0025] The first universal joint includes a first connecting shaft, first connecting lugs symmetrically arranged on the inner end of the first connecting shaft, and a first flange arranged on the outer end of the first connecting shaft. The first flange is fixed to the inner end of the corresponding third rotating shaft with bolts.

[0026] The second universal joint includes a second connecting shaft, second connecting lugs symmetrically arranged at one end of the second connecting shaft, and a second flange arranged at the other end of the second connecting shaft. The second flange is fixed to the corresponding end of the second rotating shaft with bolts.

[0027] The cross shaft is movably connected between the first connecting ear and the second connecting ear;

[0028] The second connecting shaft has a second square through slot in the middle for inserting a square transmission arm.

[0029] Compared with the prior art, the beneficial effects of the present invention are: the present invention continuously monitors the edge position of the conveyor belt through a position sensor, accurately judges the direction and degree of deviation, controls the drive motor to adjust the side support roller assembly, and then links the side bracket roller assembly to tilt. Through "precise mechanical adjustment", "on-demand correction" is achieved, avoiding damage to the conveyor belt caused by excessive operation.

[0030] This invention adjusts the distance between the side support rollers and the middle support rollers, making it adaptable to conveyor belts of different specifications from narrow to wide without the need to replace support components. Furthermore, regardless of the width adjustment, the middle support rollers, side support rollers, and side idler rollers can maintain synchronous rotation, preventing transmission disconnection, eliminating relative friction, and extending the service life of the conveyor belt and support rollers.

[0031] This invention utilizes a "correction-lubrication" linkage structure to simultaneously correct the conveyor belt and lubricate the surface of the side idler rollers, achieving "correction as lubrication," eliminating the need for manual operation and preventing lubrication omissions.

[0045] 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example:

[0047] Please see Figure 1-12 The present invention provides a technical solution:

[0048] An intelligent belt conveyor with a correction mechanism includes a conveyor frame 1 and a control console 2. The top two ends of the conveyor frame 1 are respectively provided with an active roller 3 and a driven roller 4 for driving the conveyor belt.

[0049] The control console 2 includes a touch screen and a PLC built into the touch screen. A servo motor is installed on the conveyor frame 1. The output end of the servo motor is equipped with a chain gear. One end of the drive roller 3 is also equipped with a chain gear. A chain is connected between the chain gears.

[0050] The servo motor is controlled by the PLC. The servo motor drives the drive roller 3 to rotate, thereby causing the conveyor belt to rotate between the drive roller 3 and the driven roller 4.

[0051] The upper end of the conveyor frame 1 is provided with mounting plates 11 at equal intervals. The upper part of the middle of the mounting plate 11 is provided with an intermediate support roller assembly 8, a side support roller assembly 9 connected to both sides of the intermediate support roller assembly 8, and a side bracket roller assembly 6 connected to the end of the side support roller assembly 9.

[0052] The intermediate support roller assembly 8 includes an intermediate U-shaped seat 801 fixed at the middle of the upper end of the mounting plate 11, an intermediate support roller 804 movably connected within the intermediate U-shaped seat 801, and a square transmission arm 806 fixed at the middle of the intermediate support roller 804.

[0053] A first bearing cylinder 802 is fixed to the outer side wall of the intermediate U-shaped seat 801. A first bearing 803 is provided inside the first bearing cylinder 802. A first rotating shaft 805 is provided in the middle of the intermediate support roller 804. The first bearing 803 is sleeved on the first rotating shaft 805.

[0054] The side support roller assembly 9 includes a side U-shaped seat 901 slidably connected to the mounting plate 11 and a side support roller 903 movably connected within the side U-shaped seat 901. A second bearing cylinder 902 is fixed to the outer side wall of the side U-shaped seat 901. A second bearing 909 is provided inside the second bearing cylinder 902. A second rotating shaft 910 is provided in the middle of the side support roller 903. The second bearing 909 is sleeved on the second rotating shaft 910.

[0055] The second rotating shaft 910 has a first square through slot 911 in the middle for inserting the square transmission arm 806. This connection method ensures the stability of the second rotating shaft 910 when it moves with the side U-shaped seat 901, and can drive the side support roller 903 to rotate synchronously when the middle support roller 804 rotates. The middle support roller 804 and the side support roller 903 are supported at the bottom of the conveyor belt. When the conveyor belt rotates, the middle support roller 804 and the side support roller 903 rotate under the action of friction. At this time, the rotational connection between the middle support roller 804 and the side support roller 903 ensures that the middle support roller 804 and the side support roller 903 rotate synchronously.

[0056] The mounting plate 11 has a limiting sliding groove 110 in the middle, and the lower end of the side U-shaped seat 901 has a limiting slider 905 that slides in the limiting sliding groove 110. The limiting slider 905 has a rack 904 on its side.

[0057] The side support roller assembly 6 includes a U-shaped support 604 movably connected to the upper end of the conveyor frame 1 and a lubricating oil open box 602 fixed in the middle of the upper end of the U-shaped support 604. The upper end of the conveyor frame 1 is provided with an L-shaped frame 12, and the L-shaped frame 12 is provided with a sloping groove 121. The support rod 603 in the middle of the lower end of the U-shaped support 604 is slidably connected to the sloping groove 121 at both ends.

[0058] The inclined groove 121 provides guidance for the movement of the support rod 603, ensuring that the U-shaped bracket 604 and the side roller 601 move along the preset trajectory when tilted synchronously, avoiding poor contact between the side roller 601 and the conveyor belt caused by the offset of the U-shaped bracket 604, thereby ensuring the stability of the correction effect; at the same time, this sliding fit structure is simple, which can reduce frictional loss between components and extend service life.

[0059] The side roller 601 is movably connected to the U-shaped bracket 604, and the bottom of the side roller 601 is located inside the lubricating oil open box 602. The side roller 601 and the corresponding second rotating shaft 910 are connected by a universal joint transmission assembly.

[0060] A piston 907 is fixed to the end of the extension rod 906 in the middle of the side of the U-shaped seat 901.

[0061] The lubrication assembly 10 includes a pneumatic cylinder 1001 fixed on the mounting plate 11, lubricating oil tanks 1002 located on both sides of the pneumatic cylinder 1001, an air pipe 1003 connecting the side of the pneumatic cylinder 1001 and the upper part of the lubricating oil tank 1002, and a hose 1004 connecting the bottom of the lubricating oil tank 1002 and the inside of the lubricating oil open box 602. The piston 907 is slidably engaged in the pneumatic cylinder 1001. During the correction, the movement of the side U-shaped seat 901 directly drives the piston 907 to slide, thereby squeezing the lubricating oil in the lubricating oil tank 1002 through air pressure changes, realizing the synchronous action of "correction and lubrication". There is no need to set up an additional lubrication power source, which simplifies the equipment structure, reduces energy consumption, and ensures that the lubrication action and the correction action are carried out synchronously, avoiding the aggravated wear of the side roller 601 due to lack of lubrication.

[0062] The inner wall of the open lubricating oil box 602 is equipped with a brush 610. The open lubricating oil box 602 stores lubricating oil, and the bottom of the side roller 601 is immersed in it for basic lubrication. The brush 610 can evenly apply the lubricating oil to the surface of the side roller 601 and the bearing, avoiding local accumulation or leakage of lubricating oil and ensuring comprehensive and uniform lubrication. At the same time, the open lubricating oil box 602 can prevent lubricating oil splashing, reduce lubricating oil waste, and keep the equipment clean.

[0063] A third rotating shaft 605 is provided in the middle of the side roller 601. A third bearing cylinder 608 is fixed at the upper end of the U-shaped bracket 604. A third bearing 609 is provided inside the third bearing cylinder 608 and sleeved on the third rotating shaft 605. The universal joint transmission assembly includes a first universal joint fixed to the inner end of the corresponding third rotating shaft 605, a second universal joint fixed to the end of the corresponding second rotating shaft 910, and a cross shaft 607 connecting the first universal joint and the second universal joint. The first universal joint includes a first connecting shaft 606, a first connecting lug 6061 symmetrically arranged on the inner end of the first connecting shaft 606, and a first flange 6062 arranged on the outer end of the first connecting shaft 606. The first flange 6062 is fixed to the inner end of the corresponding third rotating shaft 605 with bolts. The second universal joint includes a second connecting shaft 908, a second connecting lug 9083 symmetrically arranged on one end of the second connecting shaft 908, and a second flange 9081 arranged on the other end of the second connecting shaft 908. The second flange 9081 is fixed to the end of the corresponding second rotating shaft 910 with bolts.

[0064] The cross shaft 607 is movably connected between the first connecting ear 6061 and the second connecting ear 9083.

[0065] The second connecting shaft 908 has a second square through slot 9082 in the middle for inserting the square transmission arm 806.

[0066] The side idler roller 601 and the corresponding side support roller 903 are connected by a universal joint transmission assembly. This connection method can accommodate the movement of the side U-shaped seat 901 and ensures that the power and displacement of the second rotating shaft 910 can be accurately transmitted to the third rotating shaft 605 when the side idler roller 601 adjusts its angle, avoiding component damage caused by rigid connection and ensuring the smoothness of the correction action.

[0067] When the side support roller 903 rotates, the universal joint transmission assembly ensures that the side idler roller 601 rotates synchronously. This synchronous rotation of the middle support roller 804, the side support roller 903, and the side idler roller 601 further reduces the friction when the conveyor belt rotates.

[0068] A drive motor 7 is mounted on the lower middle part of the mounting plate 11; the gear 71 on the upper end of the drive motor 7 meshes between the racks 904 distributed in front and behind. The drive motor 7 is controlled by a PLC, and the drive motor 7 drives the gear 71 to rotate, thereby causing the gear 71 to drive the two sets of side U-shaped seats 901 to move closer or further apart through the racks 904.

[0069] The gear 71 at the upper end of the drive motor 7 meshes between two sets of racks 904. This meshing transmission method can convert the rotational motion of the drive motor 7 into the linear motion of the side U-shaped seat 901. It has high transmission efficiency and precise position control. The two sets of side U-shaped seats 901 can be easily moved closer or further apart by the forward and reverse rotation of the gear 71, providing stable power for the correction action. At the same time, the gear and rack transmission structure is simple, easy to maintain, and can adapt to long-term high-frequency correction operations.

[0070] Several sets of position sensors 5 are evenly spaced on both sides of the upper end of the conveyor frame 1;

[0071] The position sensor 5 is connected to the PLC. The position sensor 5 is evenly distributed on both sides of the upper end of the conveyor frame 1, which can cover the edge monitoring range of the conveyor belt in all directions and ensure timely capture of deviation signals. The position sensor 5 interacts directly with the PLC of the control console 2. The signal transmission delay is low, which can realize real-time detection and fast response of deviation, and avoid serious deviation of the conveyor belt or material spillage due to detection lag.

[0072] The PLC is connected to the drive motor 7 for control. After receiving the deviation signal from the position sensor 5, the PLC can accurately determine the direction and degree of deviation, and then control the direction, speed and running time of the drive motor 7 to achieve "on-demand correction", avoid excessive correction that causes the conveyor belt to run in the opposite direction, and improve the correction accuracy.

[0073] Position sensor 5 adopts a non-contact detection principle, and its installation method and working logic are as follows:

[0074] Position sensors 5 are evenly distributed on both sides of the upper end of the conveyor frame 1. The monitoring range of each side position sensor 5 accurately covers the "preset running trajectory zone" of the conveyor belt edge. That is, when the conveyor belt is running normally, the edge should be in the "non-trigger area" of the sensor; when the conveyor belt deviates, the edge will shift to one side and enter the "trigger area" of the corresponding side sensor. For example, if the normal width of the conveyor belt is 1 meter, the position sensors 5 on both sides are aligned with the outer edge of the conveyor belt 5-10mm. During normal operation, the edge does not block the sensor, but when the belt deviates, the edge will block one side sensor.

[0075] Real-time edge displacement sensing: Taking the most commonly used infrared through-beam sensor as an example, the position sensor 5 consists of a "transmitter" and a "receiver," which are installed at corresponding positions on the same side of the conveyor frame 1. Infrared light passes laterally through the monitoring area outside the edge of the conveyor belt.

[0076] When the conveyor belt is running normally, the infrared light is unobstructed, the receiving end continuously receives the complete light signal, and the sensor is in the "no signal output" state.

[0077] When the conveyor belt deviates to this side, the edge of the conveyor belt will block the infrared light, and the intensity of the light signal received by the receiver will drop sharply or be interrupted. The position sensor 5 will be "triggered" immediately to confirm that the conveyor belt has deviated.

[0078] When the position sensor 5 detects that the conveyor belt on the conveyor frame 1 is off-track, the control console 2 controls the drive motor 7 to work. The drive motor 7 drives the side support roller assembly 6 to adjust the tilt angle through the side support roller assembly 9, so that the side support roller assembly 6 contacts the conveyor belt and corrects the conveyor belt. At the same time, the side support roller assembly 9 also lubricates the side support roller 601 of the side support roller assembly 6 through the lubrication assembly 10 on the mounting plate 11.

[0079] Traditional belt conveyors have fixed support roller positions, which can only accommodate conveyor belts of a single width. However, this invention achieves full bottom coverage support for conveyor belts of different widths through the movable design of the side support roller assembly 9.

[0080] When the width of the conveyor belt changes, the PLC controls the drive motor 7 to rotate the gear 71. This, via the rack 904, drives the two sets of side U-shaped supports 901 to move away from each other along the limiting sliding groove 110. The two sets of side U-shaped supports 901 move outwards, and the side support rollers 903 expand outwards simultaneously, forming a wide-spacing support layout with the central support roller 804. This ensures uniform force distribution on the bottom of the wide conveyor belt. This adjustable design overcomes the width limitations of the support structure, adapting to different specifications of conveyor belts from narrow to wide, significantly improving the equipment's versatility.

[0081] A breakthrough was achieved through the insertion transmission structure of the intermediate support roller assembly 8 and the side support roller assembly 9.

[0082] A square transmission arm 806 is fixed in the middle of the intermediate support roller 804. A first square through groove 911 is provided in the middle of the second rotating shaft 910 of the side support roller assembly 9. A second square through groove 908 is provided in the middle of the second connecting shaft 908 of the universal joint transmission assembly. The square transmission arm 806 is inserted into both the first square through groove 911 and the second square through groove 9082.

[0083] Regardless of how far the side U-shaped seat 901 moves as the conveyor belt width is adjusted, the square drive arm 806 always maintains an interlocking engagement with the square through slot. When the conveyor belt is running, friction drives the central support roller 804 to rotate, which in turn drives the two side support rollers 903 and the side idler rollers 601 to rotate synchronously via the square drive arm 806, achieving synchronous transmission of the three components: central-side-support. This design ensures that all support rollers can rotate synchronously with the conveyor belt when supporting conveyor belts of different widths, avoiding frictional damage to the conveyor belt caused by stationary support rollers.

[0084] The synchronous rotation of the intermediate support roller 804, the side support roller 903, and the side idler roller 601 eliminates relative friction.

[0085] When the conveyor belt is running, the friction force drives the intermediate support roller 804 to rotate, and the power is directly transmitted to the side support roller 903 through the square transmission arm 806. Then, the side idler roller 601 is driven to rotate synchronously through the universal joint transmission assembly (cross shaft 607, first / second universal joint).

[0086] The rotational speed of the three rollers is perfectly matched with the speed of the conveyor belt, avoiding the relative sliding friction between the support rollers (stationary / lagging) and the conveyor belt, significantly reducing wear on the bottom and edges of the conveyor belt, and extending the service life of the conveyor belt.

[0087] Uniform force protection conveyor belt structure: When the three rollers rotate synchronously, the supporting force on the conveyor belt is in a "uniform distribution" state. The middle support roller 804 supports the middle of the conveyor belt, the side support rollers 903 assist in supporting the two sides, and the side idler rollers 601 fit against the edge. The rotation direction of the three is consistent with the running direction of the conveyor belt, so there will be no "pulling force" due to local speed differences. This prevents problems such as local wrinkles and tears in the conveyor belt, and is especially suitable for the long-term stable operation of wide conveyor belts (which are prone to deformation due to uneven support).

[0088] Sliding adjustment does not affect the continuity of transmission: The side U-shaped seat 901 of the side support roller 903 is slidably connected to the limiting sliding groove 110 of the mounting plate 11 through the limiting slider 905. When adjusting the width of the conveyor belt, the drive motor 7 drives the side U-shaped seat 901 to move closer to or away from the middle support roller 804. Since the square transmission arm 806 is a "long strip" structure, it can slide synchronously with the movement of the side support roller 903 in the first square groove 911 and the second square groove 9082, always maintaining the plug-in fit, ensuring that the power transmission is uninterrupted, and the rotation state of the three rollers is not affected by the width adjustment.

[0089] Universal joint compensation for angular deviation ensures smooth rotation: When the side idler roller 601 tilts with the adjustment of the conveyor belt width or the correction action, the cross shaft 607 of the universal joint transmission assembly can flexibly adapt to the angle changes of the first connecting ear 6061 and the second connecting ear 9083. No matter how much the side idler roller 601 tilts, the cross shaft 607 can smoothly transmit the rotational power of the side support roller 903 to the third rotating shaft 605, avoiding the "jamming" or "shaft breakage" problems caused by rigid transmission due to angular deviation, ensuring that the side idler roller 601 always maintains smooth rotation during the adjustment process and does not affect the normal operation of the conveyor belt.

[0090] Specifically, during use, the operator sends a start command through the touch screen of the control console 2. After receiving the command, the PLC built into the touch screen first controls the servo motor installed on the conveyor frame 1 to start.

[0091] The chain gear at the output end of the servo motor is connected to the chain gear at one end of the drive roller 3 via a chain. When the servo motor rotates, it drives the drive roller 3 to rotate synchronously. Since the conveyor belt is installed between the drive roller 3 and the driven roller 4, the rotation of the drive roller 3 drives the conveyor belt to run through friction. The driven roller 4 rotates passively with the conveyor belt, thus realizing the material conveying function.

[0092] Conveyor belt misalignment detection:

[0093] During the operation of the conveyor belt, several sets of position sensors 5, which are equally spaced on both sides of the upper end of the conveyor frame 1, continuously monitor the edge position of the conveyor belt.

[0094] When the conveyor belt deviates from its preset running trajectory due to factors such as uneven material loading or roller wear, the edge of the conveyor belt will deviate from the preset running trajectory, triggering the position sensor 5 on the corresponding side. The position sensor 5 transmits the deviation signal to the PLC of the control console 2. The PLC quickly identifies the direction and degree of deviation, providing a signal basis for subsequent correction actions.

[0096] After receiving the deviation signal, the PLC immediately controls the drive motor 7 at the lower middle part of the mounting plate 11 to start; the drive motor 7 is precisely controlled by the PLC to control the speed and direction, and the gear 71 at its upper end rotates accordingly.

[0097] The gear 71 meshes between the racks 904 distributed in front and behind, and the racks 904 are located on the side of the limiting slider 905 at the lower end of the side U-shaped seat 901. When the gear 71 rotates, it drives the two sets of side U-shaped seats 901 to move closer to each other along the limiting sliding groove 110 in the middle of the mounting plate 11 through the racks 904.

[0098] The side U-shaped seat 901 is the core component of the side support roller assembly 9. Its movement drives the overall position adjustment of the side support roller assembly 9. The second rotating shaft 910 of the side support roller assembly 9 has a first square through groove 911 in the middle, which is inserted into the square transmission arm 806 of the middle support roller assembly 8. At the same time, the end of the second rotating shaft 910 is connected to the third rotating shaft 605 of the side bracket roller assembly 6 through the universal joint transmission assembly. Therefore, when the side U-shaped seat 901 moves, it will drive the universal joint transmission assembly to move synchronously through the second rotating shaft 910.

[0099] The first universal joint of the universal joint drive assembly is fixed to the inner end of the third rotating shaft 605 via the first flange 6062, and the second universal joint is fixed to the end of the second rotating shaft 910 via the second flange 9081. The cross shaft 607 is movably connected between the first connecting ear 6061 and the second connecting ear 9083. This flexible transmission structure can adapt to angle changes, ensuring that the displacement of the second rotating shaft 910 can be converted into the angle adjustment of the third rotating shaft 605, thereby driving the side roller 601 to tilt.

[0100] The side roller 601 is movably connected to the U-shaped bracket 604, and the support rod 603 at the lower middle part of the U-shaped bracket 604 is slidably connected to the inclined groove 121 of the L-shaped frame 12 at both ends.

[0101] The support rod 603 slides along the inclined groove 121, the tilt angle of the side idler roller 601 changes, and the U-shaped bracket 604 adjusts its posture synchronously with the side idler roller 601, so that the side idler roller 601 makes close contact with the side edge of the conveyor belt that is running off track, and pushes the conveyor belt back to the preset running track through friction, thus completing the correction action.

[0102] Synchronous lubrication maintenance phase:

[0103] While the side U-shaped seat 901 moves to correct its deviation, the piston 907 fixed at the end of the extension rod 906 in the middle of its side slides synchronously with the side U-shaped seat 901, and the piston 907 slides into the pneumatic cylinder 1001 of the lubrication assembly 10. The sliding of the piston 907 changes the air pressure in the pneumatic cylinder 1001.

[0104] The side of the pneumatic cylinder 1001 is connected to the upper part of the lubricating oil tank 1002 via an air pipe 1003. When the air pressure inside the pneumatic cylinder 1001 changes, the air inside the lubricating oil tank 1002 is squeezed through the air pipe 1003, causing the lubricating oil inside the lubricating oil tank 1002 to be transported through the bottom hose 1004 to the lubricating oil open box 602 of the side bracket roller assembly 6 under the action of air pressure.

[0105] The bottom of the side idler roller 601 is located inside the open lubricating oil box 602, and the inner wall of the open lubricating oil box 602 is equipped with a brush 610. When the side idler roller 601 rotates, its bottom is immersed in lubricating oil. At the same time, the brush 610 evenly applies lubricating oil to the surface of the side idler roller 601 and the bearings at both ends, realizing real-time lubrication of the side idler roller 601. A lubricating film is quickly and evenly formed on the surface of the side idler roller 601. Then, the side idler roller 601 contacts the conveyor belt, thereby reducing the friction between the side idler roller 601 and the conveyor belt, reducing the degree of wear, which is conducive to improving the service life of the side idler roller 601 and the conveyor belt. At the same time, it reduces maintenance costs and ensures the normal operation of the conveyor belt.

[0106] Once the conveyor belt is corrected to the preset track, the position sensor 5 detects that the edge of the conveyor belt has returned to the normal position and then sends a reset signal to the PLC. The PLC controls the drive motor 7 to stop working, the side U-shaped seat 901 stops moving, the side roller 601 returns to its initial posture, and the correction process ends.

[0107] Position sensor 5 continues to monitor the position of the conveyor belt in real time. If the belt deviates again, the equipment repeats the above correction and lubrication process to ensure the continuous and stable operation of the conveyor belt.

[0108] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
