Description

Technical Field

[0001] The present invention relates to the technical field of deviation-correcting devices, and in particular to a conveyor belt transport device with a self-correcting function. Background Art

[0002] A conveyor belt (also known as a conveyor belt) is an automated device that uses a continuously moving belt body to transport materials or items. 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 complete the transportation of large quantities of materials, reducing human intervention. During operation, the conveyor belt is 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 number CN114572639A discloses a conveyor belt deviation correction device, which relates to the technical field of conveyor belt equipment. The device comprises a conveyor belt body, a bottom plate, and deviation correction rollers. The deviation correction rollers comprise 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 bottom plate. The conveyor belt is draped over the deviation correction rollers. A hard strip is provided in the middle of the conveyor belt. The width of the hard strip matches the width of the intermediate roller. The above-mentioned correction device uses a telescopic rod to drive the side rollers to rotate, and corrects the deviation of the conveyor belt by changing the angle of the side rollers. However, the above-mentioned correction device requires the telescopic rod to perform an extension and retraction action when correcting the deviation. Therefore, it does not correct the deviation by itself according to the deviation of the conveyor belt, but changes the force on the conveyor belt through the telescopic rod to achieve the purpose of correction. Therefore, the above-mentioned correction device requires the staff to visually observe the conveyor belt and find that the conveyor belt is deviated before operating the telescopic rod. This not only increases the workload of the staff, but also makes it impossible for the conveyor belt to be corrected in the first time. Summary of the Invention

[0006] As a further technical solution of the present invention, the top middle and both ends of the front rotating frame are rotatably connected with front rollers, and the three are distributed in a V shape; the tops of both ends of the front rotating frame are rotatably connected with front correcting rollers, and the two front correcting rollers are respectively located on the outside of both 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 sections of the two push-pull rods, and the tops of the multiple support seats are provided with limiting grooves for accommodating the push-pull rods; the initial positions of the two connecting parts are both located in the middle section of the movable groove.

[0008] As a further technical solution of the present invention, the bottom ends of the middle frame and the front frame are fixedly connected to the top of the truss; the four corners of the bottom of the truss are fixedly connected with support legs; the central axes at both ends of the two driving rollers are rotatably connected to the truss through seat bearings; the central axis at one end of one of the driving rollers is transmission-connected to the output end of the reducer, and the input end of the reducer is transmission-connected to the output shaft of the motor; the reducer and the motor are both fixedly connected to the truss.

[0011] Beneficial effects: 1. In the present invention, when the end of the conveyor belt deviates, the conveyor belt will squeeze the multiple front rollers or the multiple rear rollers, thereby causing the front rotating frame or the rear rotating frame to rotate and drive the multiple front rollers or the multiple rear rollers to change positions, thereby generating a thrust in the opposite direction of the deviation to the deviated conveyor belt, and correcting the deviated conveyor belt; the multiple front rollers or the multiple rear rollers perform the deviation correction automatically due to the deviation of the conveyor belt, and do not require real-time monitoring by staff, thereby reducing the workload of staff.

[0012] When the conveyor belt is deflected slightly at one end of the front deviation-correcting assembly, the front rotating frame can drive the two push-pull rods to move, and the two push-pull rods can respectively form a pulling force and a pushing force on the middle rotating frame; when the deviation amplitude of the conveyor belt is small, the rotation angle of the front rotating frame is small, and the moving distance of the two push-pull rods is also small, so that the two connecting members cannot contact the ends of the movable groove. At this time, the front rotating frame can rotate without the middle rotating frame taking action, and the small deviation of the conveyor belt end can be corrected; when the deviation amplitude of the conveyor belt is large, and one end and the middle section of the conveyor belt are deflected near the front deviation-correcting assembly, the rotation angle of the front rotating frame increases, so that the moving distance of the two push-pull rods increases and pushes the two connecting members, thereby allowing the middle rotating frame to rotate, so that multiple middle-section rollers and multiple front rollers can correct the deviation of the conveyor belt at the same time; after the deviation correction is completed, the front rotating frame automatically resets under the pressure of the conveyor belt, and the middle-section rotating frame automatically resets under the pull of the two springs.

[0013] When the gear wheel is rotated, the gear ring is rotated, and the gear wheel is rotated, so that the gear wheel can be rotated.

[0014] 4. In the present invention, when the front rotating frame uses the two push-pull rods to drive the middle rotating frame to rotate, the two tooth plates are not engaged with the gear ring. At this time, the middle rotating frame drives the connecting rod and the tooth 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 gear ring, the two tooth plates and the two connecting rods, the two movable grooves can provide sufficient movable space for the two connecting parts, so that the middle rotating frame will not affect the front rotating frame; in summary, the front correcting assembly and the rear correcting assembly can not only move on their own, but also drive the middle correcting assembly to move, and the actions of the front correcting assembly and the rear correcting assembly do not interfere with each other, which greatly improves the flexibility of the correction work.

The ends of the two springs 16 away from the middle rotating frame 13 are fixedly connected to the top of both ends of the middle base frame 15 respectively; a connecting piece 17 is symmetrically fixedly connected to the inner side of the middle rotating frame 13, and a connecting piece 2 18 is symmetrically fixedly connected to the bottom of the middle rotating frame 13; The front deviation correction component 2 includes a front rotating frame 23, and two push-pull rods 26 are symmetrically connected to the inner side of the front rotating frame 23. The ends of the two push-pull rods 26 away from the front rotating frame 23 are each provided with a movable groove 28, and the two connecting members 17 are respectively located in the two movable grooves 28. The tops of the two connecting members 17 are integrally provided with a blocking cover, which is located outside the movable groove 28 and has a diameter greater than the width of the movable groove 28. The rear deviation correction component 3 includes a rear rotating frame 33, which is fixedly connected to a gear ring 37 in the middle of the bottom of the rear rotating frame 33, and two groups of convex teeth are symmetrically provided on one side of the gear ring 37 close to the middle rotating frame 13; the gear ring 37 is provided with a gear plate 36 on both sides adjacent to the two groups of convex teeth, and the inner side of the end of the gear plate 36 close to the gear ring 37 is provided with convex teeth; the two gear plates 36 are rotatably connected to a connecting rod 38 at one end away from the gear ring 37, and the two connecting rods 38 are rotatably connected to the two connecting members 18 at one end away from the gear plate 36.

[0018] By adopting the above technical solution, when the end of the conveyor belt 5 is offset, the conveyor belt 5 will squeeze the multiple front rollers 21 or the multiple rear rollers 31, thereby causing the front rotating frame 23 or the rear rotating frame 33 to rotate and drive the multiple front rollers 21 or the multiple rear rollers 31 to change position, thereby generating a thrust in the opposite direction of the offset to the offset conveyor belt 5, and correcting the offset conveyor belt 5; the correction of the multiple front rollers 21 or the multiple rear rollers 31 is automatically caused by the offset of the conveyor belt 5, and does not require real-time monitoring by staff, thereby reducing the workload of staff.

[0019] See also Figure 1-9 In this embodiment, the top middle and both ends of the front rotating frame 23 are rotatably connected to the front rollers 21, and the three are distributed in a V shape; the tops of both ends of the front rotating frame 23 are rotatably connected to the front deviation correcting rollers 22, and the two front deviation correcting rollers 22 are respectively located on the outside of the two 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; A plurality of support seats 27 are symmetrically provided below the middle sections of the two push-pull rods 26 , and the tops of the plurality of support seats 27 are provided with limiting grooves for accommodating the push-pull rods 26 ; the initial positions of the two connecting members 17 are both located in the middle section of the movable groove 28 .

[0020] By adopting the above technical solution, when the conveyor belt 5 is located at one end of the front deviation-correcting component 2 and a small deviation occurs, the front rotating frame 23 can drive the two push-pull rods 26 to move during rotation, and the two push-pull rods 26 can respectively form a pulling force and a pushing force on the middle rotating frame 13; when the deviation amplitude of the conveyor belt 5 is small, the rotation angle of the front 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 ends of the movable grooves 28. At this time, the front rotating frame 23 can rotate without the middle rotating frame 13 moving, which can correct the conveyor belt 5. The conveyor belt 5 is corrected by a small deviation at the end thereof; when the deviation of the conveyor belt 5 is large, and deviation occurs at both the end near the front deviation correction component 2 and the middle section, the rotation angle of the front rotating frame 23 increases, so that the moving distance of the two push-pull rods 26 increases and pushes the two connecting parts 17, thereby causing the middle section rotating frame 13 to rotate, so that multiple middle section rollers 11 and multiple front rollers 21 can correct the deviation of the conveyor belt 5 at the same time; after the deviation 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] See also Figure 1-10In this embodiment, the bottom ends of the middle chassis 15 and the front chassis 25 are fixedly connected to the top of the truss 9; the four corners of the bottom of the truss 9 are fixedly connected with support legs 10; the central axes at both ends of the two driving rollers 6 are rotatably connected to the truss 9 through seat bearings; the central axis at one end of one of the driving rollers 6 is transmission-connected to the output end of the reducer 7, and the input end of the reducer 7 is transmission-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] When the front rotating frame 23 drives the middle rotating frame 13 to rotate by the two push-pull rods 26, the two tooth plates 36 do not mesh with the gear ring 37. At this time, the middle rotating frame 13 drives the connecting rod 38 and the tooth 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 gear ring 37, the two tooth plates 36 and the two connecting rods 38, the two movable grooves 28 can provide sufficient movable space for the two connecting parts 17, so that the middle rotating frame 13 will not affect the front rotating frame 23. In summary, the front correcting component 2 and the rear correcting component 3 can not only move on their own, but also drive the middle correcting component 1 to move, and the actions of the front correcting component 2 and the rear correcting component 3 do not interfere with each other, which greatly improves the flexibility of the correction work.

[0023] See also Figure 10-14 In this embodiment, the top middle and both ends of the rear rotating frame 33 are rotatably connected to the rear rollers 31, and the three rear rollers 31 are distributed in a V shape; the tops of both ends of the rotating frame 33 are rotatably connected to the rear correction rollers 32, and the two rear correction rollers 32 are respectively located on the outside of the two 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 bottoms of both ends of the rear base frame 35 are fixedly connected to the top of the truss 9; A slide rail 39 is provided below the two tooth plates 36, and the two tooth plates 36 are slidingly connected to the two slide rails 39 through multiple sliders 30, and the tops of the multiple sliders 30 are fixedly connected to the bottoms of the two tooth plates 36; the bottoms of the two slide rails 39 are fixedly connected to multiple bases 310.

[0024] By adopting the above technical solution, when the conveyor belt 5 is slightly deviated at one end of the rear deviation-correcting component 3, the rear rotating frame 33 synchronously drives the gear ring 37 to rotate during rotation and can correct 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 gear ring 37 is small, and the convex teeth on the gear ring 37 do not mesh with the convex teeth of the tooth plate 36, and thus will not drive the tooth plate 36 to move, thereby realizing the rotation of the rear rotating frame 33 while the middle rotating frame 13 does not move, and the small deviation of the end of the conveyor belt 5 can be corrected. Deviation correction: When the conveyor belt 5 has a large deviation, and deviation occurs at one end and the middle section near the rear deviation correction component 3, the rotation angle of the rear rotating frame 33 increases, and the rotation angle of the gear ring 37 increases synchronously. During the rotation of the gear ring 37, its convex teeth can mesh with the convex teeth of the tooth plate 36 and drive the tooth plate 36 to move. When the tooth plate 36 moves, it can drive the connecting rod 38 to move, and the connecting rod 38 can drive the middle section rotating frame 13 to rotate, so that multiple middle section rollers 11 and multiple rear rollers 31 can correct the conveyor belt 5 at the same time.
