Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a redirecting roller for a belt conveyor. Background Technology

[0002] In belt conveyors, the conveyor belt is typically supported and guided by a series of rollers. Among these, the redirecting roller is a crucial component used to change the direction of the conveyor belt. By looping the conveyor belt around the redirecting roller, materials can be transported from one direction to another, adapting to different process requirements. Because the redirecting roller is located at the point where the conveyor belt's direction of travel changes, it is more prone to lateral deviation during material transport. This deviation can easily cause material spillage, and severe deviation can lead to conveyor malfunctions. Therefore, a redirecting roller capable of automatically detecting and adjusting conveyor belt deviation is needed. Utility Model Content

[0003] This invention aims to address the shortcomings of existing technologies by providing a redirecting roller for a belt conveyor.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a redirecting roller for a belt conveyor, comprising a base, a roller platform, roller supports, a roller assembly, a hydraulic cylinder, and a controller. The base is fixedly installed on the ground. One end of the roller platform is rotatably installed on the base. The fixed end of the cylinder body of the hydraulic cylinder is hinged to the base, and the telescopic end of the piston rod of the hydraulic cylinder is hinged to the bottom of the other end of the roller platform. The hydraulic cylinder is controlled by the controller. The roller supports are respectively fixedly installed on the top surfaces at both ends of the roller platform, and the roller assembly is rotatably installed between the roller supports. The roller assembly includes a cylindrical body and a frustum plate. The frustum plate is respectively fixedly installed at both ends of the cylindrical body. A pressure sensor is embedded in the outer side of the frustum plate, and the pressure sensor is electrically connected to a signal transmission device.

[0005] Furthermore, the roller assembly also includes: a roller support shaft, a connecting cover plate, a cover plate, and a bearing. The connecting cover plates are fixedly installed on both sides of the cylindrical body. A cover plate is detachably installed on the outside of the connecting cover plate. The bearing is fixedly installed between the cover plate and the connecting cover plate. The roller support shaft rotatably passes through the bearing, the connecting cover plate, and the cover plate.

[0006] Furthermore, several connecting rods are evenly installed inside the opening of the frustum plate, and bushings are fixedly installed at the inner ends of the connecting rods. The roller support shaft is rotatably inserted through the inner side of the bushings.

[0007] Furthermore, a support column is fixedly installed below the extension end of the piston rod of the hydraulic cylinder, and a sliding groove is provided on the base, with the bottom of the support column engaging in the sliding groove.

[0008] Furthermore, two spiral rubber strips are fixedly wound around the outer side of the cylindrical body. The spiral rubber strips are inclined to the axial direction of the cylindrical body and the two spiral rubber strips are inclined in opposite directions.

[0009] The beneficial effects of this utility model are as follows: A pressure sensor is fixedly installed on the truncated cylindrical plate. When the conveyor belt deviates, it exerts pressure on the truncated cylindrical plate. The pressure sensor sends a signal to the controller, which automatically controls the extension and retraction of the hydraulic cylinder, thereby changing the angle between the radial direction of the redirecting roller and the direction of movement of the conveyor belt. The redirecting roller generates a radial thrust on the conveyor belt, moving the conveyor belt back to its original position. The process of detecting and adjusting the conveyor belt deviation is automatically controlled, which effectively improves production efficiency and maintains the safety of the belt conveyor.

[0015] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] like Figures 1-3As shown, a redirecting roller for a belt conveyor includes a base 1, a roller platform 2, roller supports 3, a roller assembly 4, a hydraulic cylinder 5, and a controller 6. The base 1 is fixedly installed on the ground. One end of the roller platform 2 is rotatably installed on the base 1. The fixed end of the cylinder body of the hydraulic cylinder 5 is hinged to the base 1, and the extension end of the piston rod of the hydraulic cylinder 5 is hinged to the bottom of the other end of the roller platform 2. The hydraulic cylinder 5 is controlled by the controller 6. The roller supports 3 are respectively fixedly installed on the top surfaces of both ends of the roller platform 2. The roller assembly 4 is rotatably installed between the roller supports 3. The roller assembly 4 includes a cylindrical body 40 and a frustum plate 41. The frustum plate 41 is respectively fixedly installed at both ends of the cylindrical body 40. A pressure sensor 7 is embedded in the outer side of the frustum plate 41, and the pressure sensor 7 is electrically connected to a signal transmission device 8.

[0018] Specifically, the conveyor belt passes around the front of the cylindrical body 40, driving the roller assembly 4 to rotate between the roller supports 3. When the conveyor belt deviates, it exerts pressure on the frustum plate 41. When the conveyor belt deviates away from the hydraulic cylinder 5, the pressure sensor 7 on the left receives a pressure signal, which is transmitted to the controller 6 via the signal transmission device 8. The controller 6 controls the piston rod of the hydraulic cylinder 5 to extend, causing the roller assembly 4 to rotate relative to the base 1. The conveyor belt will automatically move back to the right. When the pressure signal on the left disappears, the controller 6 controls the piston rod of the hydraulic cylinder 5 to return to its original position. When the conveyor belt deviates towards the hydraulic cylinder 5, the pressure sensor 7 on the right receives a pressure signal, which is transmitted to the controller 6 via the signal transmission device 8. The controller 6 controls the piston rod of the hydraulic cylinder 5 to shorten, causing the conveyor belt to automatically move back to the left. When the pressure signal on the right disappears, the controller 6 controls the piston rod of the hydraulic cylinder 5 to return to its original position. The pressure sensor 7 can be an NF127 model, and the controller 6 can be a Siemens PLC module 6ES7315-2AH14-0AB0.

[0019] The roller assembly 4 further includes: a roller support shaft 42, a connecting cover plate 43, a cover plate 44, and a bearing 45. Connecting cover plates 41 are fixedly installed on both sides of the cylindrical body 40. A cover plate 44 is detachably installed on the outer side of the connecting cover plate 41. The bearing 45 is fixedly installed between the cover plate 44 and the connecting cover plate 45. The roller support shaft 42 is rotatably inserted between the bearing 45, the connecting cover plate 43, and the cover plate 44.

[0020] Specifically, the roller support shaft 42 is rotatably connected to the cylindrical body 40 via a bearing 45. The end of the bearing 45 near the middle of the cylindrical body 40 is limited by a connecting cover plate 41, and the end near both sides of the cylindrical body 40 is limited by a cover plate 44.

[0021] A plurality of connecting rods 46 are evenly installed on the inner side of the opening of the frustum plate 40. A bushing 47 is fixedly installed on the inner end of the connecting rod 46, and the roller support shaft 42 is rotatably inserted through the inner side of the bushing 47.

[0022] Specifically, the connecting rod 46 and the bushing 47 increase the stability of the frustum plate 40.

[0023] A support column 9 is fixedly installed below the piston rod extension end of the hydraulic cylinder 5, and a sliding groove is provided on the base 1, with the bottom of the support column 9 being engaged in the sliding groove.

[0024] Specifically, the piston rod of the hydraulic cylinder 5 extends and retracts, causing the roller table 2 to rotate around the rotating axis. An arc-shaped groove is opened on the base 1 with the rotation connection point of the roller table 2 and the base 1 as the center and the distance between the rotation connection point of the roller table 2 and the base 1 and the hinge point of the piston rod of the hydraulic cylinder 5 as the radius, so that the support column 9 can slide in the groove.

[0025] Two spiral adhesive strips 48 are fixedly wound around the outer side of the cylindrical body 40. The spiral adhesive strips 48 are inclined to the axial direction of the cylindrical body 40 and the two spiral adhesive strips 48 are inclined in opposite directions.

[0026] Specifically, when material spillage occurs during the conveyor's transport process, foreign objects are more likely to enter the cavity formed between the spiral rubber strips 48. As the drum rotates, the foreign objects are discharged to both sides of the drum, ensuring the cleanliness of the drum.

[0027] The working principle of this utility model is as follows: when the conveyor belt deviates, it exerts pressure on the frustum plate. The pressure sensor sends a signal to the controller, which automatically controls the extension and retraction of the hydraulic cylinder, thereby changing the angle between the radial direction of the redirecting roller and the direction of movement of the conveyor belt. The redirecting roller generates a radial thrust on the conveyor belt, moving the conveyor belt back to its original position.

[0028] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
