A conveying belt conveying device with self-correcting function

Abstract

This invention relates to a conveyor belt conveying device with self-correcting function; it relates to the technical field of correction devices, including a mid-section correction assembly. One side of the mid-section correction assembly has a front correction assembly, and the other side has a rear correction assembly. Multiple trough-shaped idlers are evenly arranged between the mid-section correction assembly and the front correction assembly, and between the mid-section correction assembly and the rear correction assembly. The front correction assembly and the rear correction assembly are located at the inner ends of the conveyor belt, respectively. When the front rotating frame drives the mid-section rotating frame to rotate using two push-pull rods, the two toothed plates are not engaged with the toothed ring. At this time, the mid-section rotating frame drives the connecting rod and the toothed plates to move in the opposite direction, without affecting the rear rotating frame. When the rear rotating frame drives the mid-section rotating frame to rotate through the toothed ring, two toothed plates, and two connecting rods, the two movable grooves provide sufficient space for the two connecting parts to move, ensuring that the mid-section rotating frame does not affect the front rotating frame.

Description

Technical Field

[0001] This invention relates to the field of belt alignment device technology, and specifically to a conveyor belt conveying device with self-alignment function. Background Technology

[0002] A conveyor belt is an automated device that uses a continuously moving belt to transport materials or goods. It is widely used in industrial production, logistics and transportation, agricultural processing and other fields. Its core advantage is that it can continuously, efficiently and stably transport large quantities of materials and reduce manual intervention. During operation, conveyor belts are prone to deviation due to various factors. Failure to correct the conveyor belt's trajectory in time will seriously affect its normal use.

[0003] Chinese Patent Publication No. CN114572639A discloses a conveyor belt correction device, which relates to the field of conveyor belt equipment technology. It includes a conveyor belt body, a base plate, and a correction roller. The correction roller includes an intermediate roller and side rollers symmetrically arranged on both sides of the intermediate roller. The intermediate roller and the side rollers are both arranged on the base plate. The conveyor belt is laid on the correction roller. A rigid strip is provided at the middle position of the conveyor belt. The width of the rigid strip is adapted to the width of the intermediate roller. The aforementioned belt-correcting device uses a telescopic rod to drive the side rollers to rotate, thereby changing the angle of the side rollers to correct the belt's deviation. However, the device requires the telescopic rod to extend and retract during correction, meaning it doesn't correct itself based on the belt's offset. Instead, it changes the force on the belt to achieve correction. Consequently, the device requires operators to visually inspect the conveyor belt and operate the telescopic rod only after the belt has shifted, increasing workload and preventing the belt from being corrected immediately. Summary of the Invention

[0004] Technical problems to be solved The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a conveyor belt conveying device with self-correcting function. By using a mid-section correction component, a front correction component, and a rear correction component in combination, it can automatically correct the deviation of each position of the conveyor belt without the need for manual operation, thereby solving the above-mentioned technical problems.

The top of each of the two connecting parts is integrally provided with a cover, which is located outside the movable groove and the diameter of the cover is greater than the width of the movable groove. The rear-mounted correction assembly includes a rear-mounted rotating frame, with a toothed ring fixedly connected to the bottom center of the rear-mounted rotating frame. The toothed ring has two sets of convex teeth symmetrically arranged on one side near the middle section of the rotating frame. Toothed plates are provided on both sides of the toothed ring adjacent to the two sets of convex teeth. The inner side of the toothed plate near the toothed ring has convex teeth. Connecting rods are rotatably connected to the ends of the two toothed plates away from the toothed ring. The ends of the two connecting rods away from the toothed plates are rotatably connected to two connecting parts.

[0006] As a further technical solution of the present invention, the top middle and both ends of the front rotating frame are rotatably connected to front idlers, and the three are distributed in a V-shape; the top of both ends of the front rotating frame are rotatably connected to front correction rollers, and the two front correction rollers are respectively located on the outer sides of the conveyor belt; the bottom middle of the front rotating frame is fixedly connected to the top of the front rotating seat, and the bottom of the front rotating seat is fixedly connected to the top middle of the front base frame.

[0007] As a further technical solution of the present invention, multiple support seats are symmetrically provided below the middle section of the two push-pull rods, and the top of the multiple support seats is provided with a limiting groove for receiving the push-pull rods; the initial position of the two connectors is located in the middle section of the movable groove.

[0008] As a further technical solution of the present invention, the bottom ends of both the middle section base frame and the front base frame are fixedly connected to the top of the truss; the four corners of the bottom of the truss are fixedly connected to the support legs; the central shafts at both ends of the two drive rollers are rotatably connected to the truss through bearing seats; the central shaft at one end of one drive roller is drivenly connected to the output end of the reducer, and the input end of the reducer is drivenly connected to the output shaft of the motor; the reducer and the motor are both fixedly connected to the truss.

[0009] As a further technical solution of the present invention, the rear rotating frame is rotatably connected to the top middle and both ends of the rear rotating frame, and the three rear rotating rollers are distributed in a V-shape; the top of both ends of the rotating frame is rotatably connected to the rear correction rollers, and the two rear correction rollers are respectively located on the outer sides of the conveyor belt; the bottom middle of the rear rotating frame is fixedly connected to the top of the rear rotating seat, and the bottom of the rear rotating seat is fixedly connected to the top middle of the rear base frame; the bottom of both ends of the rear base frame is fixedly connected to the top of the truss.

[0010] As a further technical solution of the present invention, a slide rail is provided below each of the two toothed plates, and the two toothed plates are slidably connected to the two slide rails by multiple sliders, with the tops of the multiple sliders fixedly connected to the bottoms of the two toothed plates respectively; the bottoms of the two slide rails are fixedly connected to multiple bases respectively.

[0011] Beneficial effects: 1. In this invention, when the end of the conveyor belt deviates, the conveyor belt will squeeze multiple front idlers or multiple rear idlers, thereby causing the front rotating frame or the rear rotating frame to rotate and drive the multiple front idlers or multiple rear idlers to change position, thereby generating a thrust on the deviated conveyor belt in the opposite direction of the deviation, thus correcting the deviated conveyor belt; the correction of the multiple front idlers or multiple rear idlers is automatically activated by the deviation of the conveyor belt, without the need for real-time monitoring by the staff, reducing the workload of the staff.

[0012] 2. In this invention, when the conveyor belt deviates slightly at one end of the front-mounted correction assembly, the front-mounted rotating frame rotates, driving two push-pull rods to move. The two push-pull rods exert pulling and pushing forces on the middle-mounted rotating frame, respectively. When the conveyor belt deviates slightly, the rotation angle of the front-mounted rotating frame is small, and the movement distance of the two push-pull rods is also small, preventing the two connecting parts from contacting the end of the movable groove. At this time, the front-mounted rotating frame rotates while the middle-mounted rotating frame remains stationary, thus correcting the slight deviation at the end of the conveyor belt. When the conveyor belt deviates significantly, with both the end near the front-mounted correction assembly and the middle section deviating, the rotation angle of the front-mounted rotating frame increases, increasing the movement distance of the two push-pull rods and pushing the two connecting parts, thereby causing the middle-mounted rotating frame to rotate. This allows multiple middle-mounted idlers and multiple front-mounted idlers to simultaneously correct the conveyor belt. After correction, the front-mounted rotating frame automatically resets under the pressure of the conveyor belt, while the middle-mounted rotating frame automatically resets under the pull of two springs.

[0013] 3. In this invention, when the conveyor belt deviates slightly at one end of the rear correction assembly, the rear rotating frame rotates synchronously, driving the toothed ring to rotate and correcting the conveyor belt. At this time, because the conveyor belt deviates slightly, the toothed ring rotates at a small angle, and the protruding teeth on the toothed ring do not mesh with the protruding teeth of the toothed plate, thus not causing the toothed plate to move. This allows the rear rotating frame to rotate while the middle rotating frame remains stationary, correcting the slight deviation at the end of the conveyor belt. When the conveyor belt deviates significantly, with both the end near the rear correction assembly and the middle section deviating, the rotation angle of the rear rotating frame increases, and the rotation angle of the toothed ring increases synchronously. During the rotation, the protruding teeth of the toothed ring mesh with the protruding teeth of the toothed plate, causing the toothed plate to move. When the toothed plate moves, it can drive the connecting rod to move, which in turn drives the middle rotating frame to rotate, enabling multiple middle idlers and multiple rear idlers to simultaneously correct the conveyor belt.

[0014] 4. In this invention, when the front rotating frame drives the middle rotating frame to rotate using two push-pull rods, the two toothed plates do not mesh with the toothed ring. At this time, the middle rotating frame drives the connecting rod and toothed plate to move in the opposite direction, which will not affect the rear rotating frame. When the rear rotating frame drives the middle rotating frame to rotate through the toothed ring, two toothed plates, and two connecting rods, the two movable slots can provide sufficient space for the two connecting parts to move, so that the middle rotating frame will not affect the front rotating frame. In summary, the front and rear correction components can both operate independently and drive the middle correction component to operate, and the operations of the front and rear correction components do not interfere with each other, greatly improving the flexibility of the correction work.

Detailed Implementation

[0017] Please see Figure 1-13 A conveyor belt conveying device with self-correcting function includes a middle section correction component 1. A front correction component 2 is provided on one side of the middle section correction component 1 and a rear correction component 3 is provided on the other side. Multiple trough-shaped idlers 4 are evenly arranged between the middle section correction component 1 and the front correction component 2, and between the middle section correction component 1 and the rear correction component 3. The front correction assembly 2 and the rear correction assembly 3 are located at the inner ends of the conveyor belt 5, respectively; drive rollers 6 are connected to the inner sides of both ends of the conveyor belt 5. The mid-section correction assembly 1 includes three mid-section idlers 11 arranged in a V-shape, and all three mid-section idlers 11 are rotatably connected to the mid-section rotating frame 13; the bottom of the mid-section rotating frame 13 is fixedly connected to the top of the mid-section rotating seat 14, and the bottom of the mid-section rotating seat 14 is fixedly connected to the top middle of the mid-section base frame 15; mid-section correction rollers 12 are rotatably connected to the top of both ends of the mid-section rotating frame 13, and the two mid-section correction rollers 12 are respectively located on the outer sides of both sides of the conveyor belt 5; Springs 16 are fixedly connected to the middle of both ends of the middle section rotating frame 13. The ends of the two springs 16 away from the middle section rotating frame 13 are fixedly connected to the top of both ends of the middle section base frame 15 respectively. Connector 17 is symmetrically fixedly connected to the inner side of the middle section rotating frame 13, and connector 2 18 is symmetrically fixedly connected to the bottom of the middle section rotating frame 13. The aforementioned front-mounted correction assembly 2 includes a front-mounted rotating frame 23, on which two push-pull rods 26 are symmetrically rotated and connected. Each of the two push-pull rods 26 has a movable groove 28 at the end away from the front-mounted rotating frame 23, and two connecting parts 17 are respectively located in the two movable grooves 28. The top of the two connecting parts 17 is integrally provided with a cover, which is located outside the movable groove 28 and the diameter of the cover is greater than the width of the movable groove 28. The rear-mounted correction assembly 3 includes a rear-mounted rotating frame 33. A toothed ring 37 is fixedly connected to the bottom center of the rear-mounted rotating frame 33, and two sets of protruding teeth are symmetrically arranged on the side of the toothed ring 37 near the middle section of the rotating frame 13. Toothed plates 36 are provided on both sides of the toothed ring 37 adjacent to the two sets of protruding teeth. The inner side of the toothed plate 36 near the toothed ring 37 is provided with protruding teeth. A connecting rod 38 is rotatably connected to the end of the two toothed plates 36 away from the toothed ring 37. The ends of the two connecting rods 38 away from the toothed plates 36 are rotatably connected to two connecting parts 18 respectively.

[0018] By adopting the above technical solution, when the end of the conveyor belt 5 deviates, the conveyor belt 5 will squeeze multiple front idlers 21 or multiple rear idlers 31, thereby causing the front rotating frame 23 or the rear rotating frame 33 to rotate and drive the multiple front idlers 21 or multiple rear idlers 31 to change position, thereby generating a thrust on the deviated conveyor belt 5 in the opposite direction of deviation, and correcting the deviated conveyor belt 5; the correction of the multiple front idlers 21 or multiple rear idlers 31 is automatically activated by the deviation of the conveyor belt 5, without the need for real-time monitoring by the staff, reducing the workload of the staff.

[0019] Please see Figure 1-9 In this embodiment, the front rotating frame 23 is rotatably connected to the top middle and both ends of the front rotating frame 23, and the three are distributed in a V-shape; the top of both ends of the front rotating frame 23 is rotatably connected to the front correction rollers 22, and the two front correction rollers 22 are respectively located on the outer sides of the conveyor belt 5; the bottom middle of the front rotating frame 23 is fixedly connected to the top of the front rotating seat 24, and the bottom of the front rotating seat 24 is fixedly connected to the top middle of the front base frame 25; The two push-pull rods 26 are symmetrically provided with multiple support seats 27 below the middle section, and the top of each of the multiple support seats 27 is provided with a limiting groove for receiving the push-pull rods 26; the initial position of the two connectors 17 is located in the middle section of the movable groove 28.

[0020] By adopting the above technical solution, when the conveyor belt 5 deviates slightly at one end of the front-mounted correction component 2, the front-mounted rotating frame 23 can drive the two push-pull rods 26 to move during rotation. The two push-pull rods 26 can respectively exert a pulling force and a pushing force on the middle-mounted rotating frame 13. When the deviation of the conveyor belt 5 is small, the rotation angle of the front-mounted rotating frame 23 is small, and the moving distance of the two push-pull rods 26 is also small, so that the two connecting parts 17 cannot contact the end of the movable groove 28. At this time, the front-mounted rotating frame 23 can rotate while the middle-mounted rotating frame 13 does not move, which can improve the control of the conveyor belt 5. The conveyor belt 5 is corrected for small deviations at its end; when the deviation of the conveyor belt 5 is large, and the deviation occurs at one end and the middle section near the front correction component 2, the rotation angle of the front rotating frame 23 increases, which increases the moving distance of the two push-pull rods 26 and pushes the two connecting parts 17, thereby causing the middle section rotating frame 13 to rotate, so that multiple middle section idlers 11 and multiple front idlers 21 can simultaneously correct the conveyor belt 5; after the correction is completed, the front rotating frame 23 automatically resets under the pressure of the conveyor belt 5, and the middle section rotating frame 13 automatically resets under the pull of the two springs 16.

[0021] Please see Figure 1-10In this embodiment, the bottom ends of both ends of the middle base frame 15 and the front base frame 25 are fixedly connected to the top of the truss 9; the four corners of the bottom of the truss 9 are fixedly connected to the support legs 10; the central shafts at both ends of the two drive rollers 6 are rotatably connected to the truss 9 through bearing seats; the central shaft at one end of one drive roller 6 is drivenly connected to the output end of the reducer 7, and the input end of the reducer 7 is drivenly connected to the output shaft of the motor 8; the reducer 7 and the motor 8 are both fixedly connected to the truss 9.

[0022] By adopting the above technical solution, when the front rotating frame 23 drives the middle rotating frame 13 to rotate using the two push-pull rods 26, the two toothed plates 36 do not mesh with the toothed ring 37. At this time, the middle rotating frame 13 drives the connecting rod 38 and the toothed plate 36 to move in the opposite direction, which will not affect the rear rotating frame 33. When the rear rotating frame 33 drives the middle rotating frame 13 to rotate through the cooperation of the toothed ring 37, the two toothed plates 36 and the two connecting rods 38, the two movable slots 28 can provide sufficient space for the two connecting parts 17 to move, so that the middle rotating frame 13 will not affect the front rotating frame 23. In summary, the front correction component 2 and the rear correction component 3 can both move independently and drive the middle correction component 1 to move. Moreover, the movements of the front correction component 2 and the rear correction component 3 do not interfere with each other, which greatly improves the flexibility of the correction work.

[0023] Please see Figure 10-14 In this embodiment, the rear rotating frame 33 is rotatably connected to the top middle and both ends of the rear idler roller 31, and the three rear idler rollers 31 are distributed in a V-shape; the top of both ends of the rotating frame 33 is rotatably connected to the rear correction roller 32, and the two rear correction rollers 32 are respectively located on the outer sides of the conveyor belt 5; the bottom middle of the rear rotating frame 33 is fixedly connected to the top of the rear rotating seat 34, and the bottom of the rear rotating seat 34 is fixedly connected to the top middle of the rear base frame 35; the bottom of both ends of the rear base frame 35 is fixedly connected to the top of the truss 9. Each of the two toothed plates 36 is provided with a slide rail 39 below it, and the two toothed plates 36 are slidably connected to the two slide rails 39 by multiple sliders 30 respectively. The tops of the multiple sliders 30 are fixedly connected to the bottoms of the two toothed plates 36 respectively; the bottoms of the two slide rails 39 are fixedly connected to multiple bases 310 respectively.

[0024] By adopting the above technical solution, when the conveyor belt 5 experiences a small deviation at one end of the rear correction assembly 3, the rear rotating frame 33 rotates synchronously, driving the toothed ring 37 to rotate and correcting the deviation of the conveyor belt 5. At this time, because the deviation of the conveyor belt 5 is small, the rotation angle of the toothed ring 37 is small, and the protruding teeth on the toothed ring 37 will not mesh with the protruding teeth of the toothed plate 36, thus not causing the toothed plate 36 to move. This achieves the rear rotating frame 33 rotating while the middle rotating frame 13 remains stationary, enabling correction of the small deviation at the end of the conveyor belt 5. Correction; When the deviation of the conveyor belt 5 is large, and the deviation occurs at one end and the middle section near the rear correction component 3, the rotation angle of the rear rotating frame 33 increases, and the rotation angle of the toothed ring 37 increases synchronously. During the rotation, the toothed ring 37 can mesh with the toothed plate 36 and drive the toothed plate 36 to move. When the toothed plate 36 moves, it can drive the connecting rod 38 to move. The connecting rod 38 can drive the middle section rotating frame 13 to rotate, so that multiple middle section idlers 11 and multiple rear idlers 31 can simultaneously correct the deviation of the conveyor belt 5.

[0025] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
