Description

Technical Field

[0001] This utility model relates to the field of conveyor belts, and in particular to a conveyor belt structure that prevents belt misalignment. Background Technology

[0002] Conveyor belts, as core transmission equipment in the material handling field, are widely used in many industries such as mining, metallurgy, chemical industry, logistics, and food processing. Through the cooperation of a ring-shaped belt and drive rollers, they can achieve continuous, efficient, and long-distance transport of block, granular, powdery, and packaged goods, significantly reducing manual handling costs and improving operational efficiency in production and logistics. In practical applications, the conveyor belt body is typically composed of a high-strength base belt (such as rubber base belt, polyester canvas base belt, etc.) and a wear-resistant surface layer, with both ends wrapped around drive rollers. The rotational driving force of the rollers drives the belt body in a cyclical motion, thereby completing the transfer of materials from the starting point to the end point. It is an indispensable key component in modern industrial production and logistics transportation systems.

[0003] However, during long-term operation, conveyor belts are prone to "deviation" due to various factors, meaning the conveyor belt deviates from the preset center transmission path and shifts to one or both sides. The causes of deviation are complex, mainly including insufficient roller installation precision (e.g., non-parallel axes of the two rollers, uneven wear on the roller surface), quality deviations in the conveyor belt itself (e.g., inconsistent belt edge thickness, uneven base belt tension distribution), material loading position deviation (e.g., material accumulating on one side of the belt for a long time), and environmental interference (e.g., dust or slippery materials adhering to the conveyor belt surface changing the coefficient of friction). Conveyor belt deviation not only affects the stability and accuracy of material transmission, leading to material spillage and waste, but also causes direct friction between the conveyor belt edge and the equipment support, accelerating belt wear and cracking, shortening the conveyor belt's service life, and in severe cases, even causing conveyor belt jamming and tearing, resulting in equipment downtime and significant economic losses and safety hazards in production operations. Therefore, this application proposes an anti-deviation conveyor belt structure. Utility Model Content

[0004] The main purpose of this invention is to provide a conveyor belt structure that prevents belt misalignment, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An anti-deviation conveyor belt structure includes a conveyor belt body, which is mounted on two rotating rollers. The rotating rollers are rotatably mounted on a main support frame. Two drag-reducing structures are symmetrically fixedly fitted around the edge of the conveyor belt body. Each drag-reducing structure consists of a rubber strip and a contact roller. Several contact rollers are evenly rotatably mounted inside the rubber strip. Four mounting brackets are symmetrically fixedly mounted on the upper end of the main support frame. Each mounting bracket consists of a support plate and a fixing plate. The fixing plate is fixedly mounted on the inner end of the support plate. A limit assembly is mounted on the support plate. The limit assembly consists of a limit plate, a scale, a connecting cylinder, a lead screw, and a handle. There are two scales symmetrically fixedly mounted on the outer end of the limit plate. The connecting cylinder is also fixedly mounted on the outer end of the limit plate. The lead screw is rotatably mounted on the connecting cylinder, and the handle is fixedly mounted on the outer end of the lead screw.

[0006] Preferably, the outer end of the rubber strip on the drag-reducing structure is evenly provided with several roller grooves, the contact roller is rotatably installed in the roller grooves, and the rubber strip is fixedly sleeved on the edge of the conveyor belt body.

[0007] Preferably, the fixing plate on the mounting bracket is fixedly installed on the upper end of the main support by bolts. Two through slots are symmetrically opened on the support plate, and a threaded hole is opened on the support plate between the two through slots. Both the through slots and the threaded hole penetrate the inside and outside of the support plate.

[0008] Preferably, the limiting plate on the limiting assembly is located inside the support plate, and the inner end of the limiting plate is in contact with the contact roller.

[0009] Preferably, the lead screw on the limiting assembly is installed in a threaded hole, the handle is located on the outside of the support plate, and the scale passes through the through groove.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By fixing a drag-reducing structure consisting of rubber strips and contact rollers onto the conveyor belt body, and fixing a mounting frame consisting of a support plate and a fixing plate to the upper end of the main support, and installing a limiting assembly consisting of a limiting plate, a scale, a connecting cylinder, a lead screw, and a handle on the mounting frame, the drag-reducing structure, mounting frame, and limiting assembly work together to limit the conveyor belt body and prevent it from deviating. Simultaneously, the presence of the contact rollers on the drag-reducing structure causes rolling friction between the drag-reducing structure and the limiting plate on the limiting assembly, thus limiting the frictional resistance experienced by the conveyor belt body while simultaneously limiting its movement. With lower force, energy loss due to friction is effectively reduced, thus ensuring the efficiency of the conveyor belt's rotation and avoiding a decrease in conveying speed or wasted power. Furthermore, by rotating the handle, the lead screw rotates within the threaded hole of the mounting bracket support plate. During the rotation of the lead screw, the connecting cylinder and the connected limiting plate move synchronously. Combined with a scale, the displacement of the limiting plate can be accurately observed, thereby enabling flexible adjustment of the limiting plate's position. The position of the limiting plate can be adjusted according to the actual width of the conveyor belt, ensuring that the limiting effect is always in the best state, thus improving the applicability and practicality of the structure.

Detailed Implementation

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, an anti-deviation conveyor belt structure includes a conveyor belt body 1, which is mounted on two rotating rollers 5. The rotating rollers 5 are rotatably mounted on a main support 6. Two drag-reducing structures 2 are symmetrically fixedly sleeved on the edge of the conveyor belt body 1. The drag-reducing structure 2 consists of rubber strips 7 and contact rollers 9. Several contact rollers 9 are uniformly rotatably mounted inside the rubber strips 7. Four mounting brackets 3 are symmetrically fixedly mounted on the upper end of the main support 6. The mounting brackets 3 consist of support plates 10 and fixing plates 11. The fixing plates 11 are fixedly mounted on the inner end of the support plates 10. The support plates 10 are equipped with... A limiting component 4 is provided, consisting of a limiting plate 14, a scale 15, a connecting cylinder 16, a lead screw 17, and a handle 18. Two scales 15 are symmetrically and fixedly installed on the outer ends of the limiting plate 14. The connecting cylinder 16 is also fixedly installed on the outer end of the limiting plate 14. The lead screw 17 is rotatably mounted on the connecting cylinder 16. The handle 18 is fixedly installed on the outer end of the lead screw 17. A drag-reducing structure 2, consisting of a rubber strip 7 and a contact roller 9, is fixedly sleeved on the conveyor belt body 1. A mounting frame 3, consisting of a support plate 10 and a fixing plate 11, is fixedly installed on the upper end of the main support 6. The mounting frame 3 is equipped with a limiting component 4 consisting of a limiting plate 14, a scale 15, a connecting cylinder 16, a lead screw 17, and a handle 18. This allows the drag-reducing structure 2, in conjunction with the mounting frame 3 and the limiting component 4, to limit the conveyor belt body 1 and prevent it from deviating. Simultaneously, the presence of the contact roller 9 on the drag-reducing structure 2 results in rolling friction between the drag-reducing structure 2 and the limiting plate 14 on the limiting component 4. This minimizes the frictional resistance experienced by the conveyor belt body 1 while it is being limited, effectively reducing energy loss due to friction and ensuring the smooth operation of the conveyor belt body. 1. Improves the efficiency of rotary conveying, avoiding a decrease in conveying speed or wasted power; and by rotating the handle 18, the lead screw 17 rotates within the threaded hole 13 of the support plate 10 of the mounting frame 3. During the rotation of the lead screw 17, it pushes the connecting cylinder 16 and the connected limiting plate 14 to move synchronously. Combined with the scale 15, the displacement of the limiting plate 14 can be accurately observed, thereby realizing flexible adjustment of the position of the limiting plate 14. The position of the limiting plate 14 can be adjusted according to the actual width of the conveyor belt body 1, ensuring that the limiting effect is always in the best state, thus improving the applicability and practicality of the structure.

[0015] Specifically, the outer end of the rubber strip 7 on the drag-reducing structure 2 is evenly provided with several roller grooves 8. The contact roller 9 is rotatably installed in the roller grooves 8. The rubber strip 7 is fixedly sleeved on the edge of the conveyor belt body 1. The fixing plate 11 on the mounting frame 3 is fixedly installed on the upper end of the main support 6 by bolts. Two through grooves 12 are symmetrically provided on the support plate 10. A threaded hole 13 is provided on the support plate 10 between the two through grooves 12. Both the through grooves 12 and the threaded hole 13 penetrate the support plate 10 inside and out. The limiting plate 14 on the limiting component 4 is located inside the support plate 10, and the inner end of the limiting plate 14 contacts the contact roller 9. The lead screw 17 on the limiting component 4 is installed in the threaded hole 13. The handle 18 is located outside the support plate 10. The scale 15 passes through the through groove 12. The position of the limiting component 4 is as close as possible to the rotating roller 5. During specific installation, the upper end of the main support 6 is... Four symmetrically fixed mounting brackets 3 are set in the area near the rotating roller 5. The reason for this arrangement is that the rotating roller 5 is the core component that drives the movement of the conveyor belt body 1. The conveyor belt body 1 is more prone to deviation due to uneven force in the area near the rotating roller 5. By installing the limiting component 4 close to the rotating roller 5, the position of the conveyor belt body 1 can be corrected in time when the limiting plate 14 contacts the contact roller 9 in the drag reduction structure 2 at the edge of the conveyor belt body 1 as soon as deviation occurs, so as to prevent the deviation trend from expanding further. This improves the timeliness and effectiveness of deviation prevention. At the same time, since the limiting component 4 is close to the rotating roller 5, it can also reduce the excessive stretching or friction of the conveyor belt body 1 in the area away from the rotating roller 5 due to deviation, better protect the structural integrity of the conveyor belt body 1 and extend its service life.

[0016] In use, the goods to be transported are first placed on the upper surface of the conveyor belt body 1. Then, the drive device is started to drive the rotating roller 5 to rotate on the main support 6. When the rotating roller 5 rotates, it drives the conveyor belt body 1 to move synchronously through friction. During the movement of the conveyor belt body 1, the goods on its surface can be transported from one end to the other. When the conveyor belt body 1 is transporting goods with the rotating roller 5, the working state of the drag reduction structure 2 is as follows: the drag reduction structure 2 moves synchronously with the conveyor belt body 1. Since the inner end of the limiting plate 14 of the limiting component 4 is always in contact with the contact roller 9 of the drag reduction structure 2, when the conveyor belt body 1 has a tendency to deviate, the limiting plate 14 will generate a blocking force on the contact roller 9, thereby limiting the deviation of the conveyor belt body 1 through the rubber strip 7. At the same time, the contact roller 9 rolls and rubs against the limiting plate 14 in the roller groove 8 of the rubber strip 7 as the conveyor belt body 1 moves. To reduce frictional resistance between the two and avoid affecting the conveying efficiency of the conveyor belt body 1 due to friction, the method for adjusting the position of the limiting plate 14 according to the actual width of the conveyor belt body 1 is as follows: First, observe the actual width of the conveyor belt body 1 to determine the direction and approximate distance that the limiting plate 14 needs to be adjusted. Then, manually rotate the handle 18 of the limiting component 4. The handle 18 drives the lead screw 17 to rotate in the threaded hole 13 of the support plate 10. During the rotation of the lead screw 17, it pushes the connected connecting cylinder 16 to move. The connecting cylinder 16 drives the limiting plate 14 to move synchronously. At this time, the scale 15 at the outer end of the limiting plate 14 will move synchronously in the through groove 12 of the support plate 10. By observing the scale changes on the scale 15, the displacement of the limiting plate 14 can be precisely controlled until the limiting plate 14 contacts the drag-reducing structure 2 at the edge of the conveyor belt body 1. Then, stop rotating the handle 18.

[0017] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
