Description

Technical Field

[0001] The invention relates to the technical field of belt conveyors, in particular to a roller of a belt conveyor. Background Art

[0002] In modern industrial production, belt conveyors, as a highly efficient material conveying equipment, are widely used in many fields such as mining, ports, chemical industry, and electric power. As one of the key components of belt conveyors, the performance of rollers directly affects the overall operation effect and conveying efficiency of belt conveyors.

[0003] Traditional belt conveyor rollers are usually fixed structures with fixed height and inclination angle. In actual application, such fixed rollers have many limitations. First, for materials with different characteristics, such as materials with different particle sizes, shapes, and fluidity, fixed rollers are difficult to provide the most suitable conveying conditions. For example, when conveying materials with small particles and good fluidity, the conveyor belt is prone to material scattering; and when conveying blocky and irregularly shaped materials, it is easy for materials to pile up and get stuck, which seriously affects the conveying efficiency and the normal conveying of materials.

[0004] Secondly, conveyor belt deviation is a common problem in the operation of belt conveyors, and fixed-structure rollers cannot effectively compensate for the deviation of conveyor belts. Once the conveyor belt deviates, it will not only cause the material to spill, but also cause friction between the conveyor belt and components such as the frame, accelerate the wear of the conveyor belt, reduce its service life, and even cause equipment failure, affecting the continuity of production. Furthermore, traditional rollers are also insufficient in adjusting the tension of conveyor belts. During the operation of the conveyor belt, uneven tension distribution will lead to excessive local force, thereby aggravating the wear of the conveyor belt and increasing the energy consumption of the equipment. It is difficult for rollers with fixed structures to effectively optimize and adjust the tension of the conveyor belt. In addition, due to the large differences in the requirements for belt conveyors in different industrial environments and conveying tasks, the versatility and adaptability of rollers with fixed structures are poor. When the conveying line needs to be modified or the type of conveyed material changes, it is often necessary to replace the entire roller system or even the conveyor, which not only increases the cost, but also consumes a lot of time and manpower.

[0022] See also Figure 1-Figure 7 A roller of a belt conveyor comprises a main body mechanism 1, the main body mechanism 1 comprises a main frame 11, a roller assembly 12 is arranged near the bottom between the main frames 11, the roller assembly 12 comprises a fixing plate 127 fixedly connected to the main frame 11, a telescopic rod 128 is arranged at the bottom position of the inner side of the fixing plate 127, a fixing seat 2 1271 is arranged near the two ends of the inner bottom of the fixing plate 127, an output end of the telescopic rod 128 is fixedly connected to a mounting plate 121, and a limiting sliding rod 127 penetrating the main frame 11 and slidably connected is arranged at the bottom position of both ends of the mounting plate 121 11. A return spring 122 is sleeved on the circumferential outer surface of the limiting slide bar 1211 located outside the main frame, a mounting seat 123 is arranged on the top of the mounting plate 121, and a limiting slide 1212 is penetrated through the top of the mounting plate 121 near the two ends, a roller 124 is installed between the mounting seats 123, a roller 2 125 is hinged on the side of the mounting seat 123 away from the roller 1 124, and a connecting arm 126 is hinged on the end of the roller 2 125 away from the mounting seat 123, and one end of the connecting arm 126 passes through the limiting slide 1212 and is hinged to the fixed seat 2 1271.

[0023] By adopting the above technical solution, the fixing seat 2 1271 at the bottom of the inner side of the fixing plate 127 near the two ends is hinged with the connecting arm 126, and plays a key role in limiting and supporting when adjusting the tilt angle of the roller 2 125. The limiting slide bars 1211 at the bottom of the two ends of the mounting plate 121 penetrate the main frame 11 and are slidably connected. On the one hand, the stability of the mounting plate 121 during the up and down movement is ensured so that it will not deviate. On the other hand, the reset spring 122 sleeved outside the limiting slide bar 121 can play a buffering role when the telescopic rod 128 pushes the mounting plate 121, preventing damage to the equipment caused by excessive pushing, and assisting the mounting plate 121 to reset when the telescopic rod 128 retracts. The mounting seat 123 at the top of the mounting plate 121 is not only used to install the roller 124, but also plays a connecting and transmission role when adjusting the angle of the roller 2 125. The limiting sliding openings 1212 are provided at the top of the mounting plate 121 near both ends, providing space for the movement of the connecting arm 126, so that the second roller 125 can adjust the tilt angle by rotating the connecting arm 126 under the drive of the first mounting seat 123. The first roller 124 and the second roller 125 cooperate with each other, and by adjusting their positions and angles according to the characteristics and conveying requirements of different materials, it is ensured that the conveyor belt can efficiently and stably complete the material conveying task.

[0024] A driving mechanism 2 is installed at one end of the main mechanism 1, and the driving mechanism 2 includes a sub-frame 21 fixedly connected to the main frame 11, a driving roller 23 is rotatably connected inside the sub-frame 21, a driving unit 22 is arranged outside the sub-frame 21, and the output end of the driving unit 22 passes through the sub-frame 21 and is fixedly connected to the driving roller 23, an adjusting rod 24 is rotatably connected to the position below the driving roller 23 inside the sub-frame 21, both ends of the adjusting rod 24 extend to the outside of the sub-frame 21 and are fixedly connected to a pull plate 26, a connecting bolt 27 is rotatably connected to the outer wall of the sub-frame 21 near the pull plate 26, a screw 271 threadedly connected to the pull plate 26 is arranged on one side of the connecting bolt 27, and an adjusting plate 25 is arranged on the outer wall of the adjusting rod 24 located inside the sub-frame 21.

[0025] By adopting the above technical solution, the screw 271 on one side of the connecting bolt 27 is threadedly connected with the pull plate 26. When the connecting bolt 27 is rotated, the screw 271 will be screwed in or out on the pull plate 26, thereby controlling the flipping angle of the pull plate 26. The flipping of the pull plate 26 will drive the adjustment rod 24 to rotate, and the adjustment plate 25 arranged on the outer wall of the adjustment rod 24 inside the sub-frame 21 will change the distance between the adjustment rod 24 and the driving roller 23 as the adjustment rod 24 rotates. The role of the adjustment plate 25 is crucial, and it can smooth the conveyor belt. During the operation of the conveyor belt, wrinkles may appear due to various factors. The adjustment plate 25 applies appropriate pressure and friction to the conveyor belt by adjusting the distance between the adjustment plate 25 and the driving roller 23, which effectively prevents the generation of wrinkles, prolongs the service life of the conveyor belt, and ensures the stable operation of the belt conveyor.

[0026] A redirecting mechanism 3 is installed at the other end of the main mechanism 1, and the redirecting mechanism 3 includes a sub-frame three 31 fixedly connected to the main frame 11, an adjusting slide 32 is provided on one side of the sub-frame three 31, an adjusting bearing 33 is slidably connected inside the adjusting slide 32, a redirecting roller 34 is rotatably connected inside the adjusting bearing 33, a bolt opening 35 is provided on the side of the adjusting bearing 33 away from the main frame 11, an adjusting bolt 36 is arranged inside the bolt opening 35, and one end of the adjusting bolt 36 passes through the sub-frame three 31 and is threadedly connected.

[0027] By adopting the above technical solution, when the tension of the conveyor belt needs to be adjusted, the operator only needs to rotate the nut on the adjusting bolt 36. Since one end of the adjusting bolt 36 passes through the sub-frame 31 and is threadedly connected, the rotation of the nut causes the adjusting bolt 36 to move axially, thereby pushing or pulling the adjusting bearing 33 to move in the adjusting slide 32. As the adjusting bearing 33 moves, the position of the redirecting roller 34 will also change accordingly, thereby achieving precise adjustment of the tension of the conveyor belt.

[0028] A plurality of fixed plates 13 are arranged at the bottom of the main frame 11, and rollers 14 are installed between the fixed plates 13. A fixed plate 3 16 is fixedly connected to a position near the driving mechanism 2 inside the main frame 11, and a limiting column 17 is arranged on a side of the fixed plate 3 16 near the driving mechanism 2. A limiting plate 15 is arranged at a position near the driving mechanism 2 at the top of the main frame 11, and a fixed plate 4 18 is arranged at a position near the redirecting mechanism 3 inside the main frame 11, and a limiting column 17 is arranged on a side of the fixed plate 4 18 near the redirecting mechanism 3, and the bottom end of the limiting column 17 extends to the outside of the main frame 11.

[0029] By adopting the above technical solution, roller three 14 cooperates with roller one 124 and roller two 125 to support and guide the conveyor belt, ensuring its smooth operation and reducing material scattering and poor conveying. The limit column 17 limits the range of movement of the components of the drive mechanism 2 to prevent excessive displacement and collision interference, thereby ensuring the stable operation of the drive mechanism 2. The limit plate 15 at the top close to the drive mechanism 2 can prevent the components above it from moving upward excessively, thereby improving the safety and reliability of equipment operation. The fixed plate four 18 near the redirecting mechanism 3 in the main frame 11, its side limit column 17 limits the movement of the components of the redirecting mechanism 3, enhances the stability of the connection between the two, ensures that the redirecting mechanism 3 operates stably when adjusting the tension of the conveyor belt, and ensures the normal operation of the conveyor. These auxiliary structures work together to improve the overall performance of the equipment.

[0030] The working principle and use process of the embodiment of the present invention are as follows: When in use, the driving mechanism 2 is started to drive the driving roller 23 to rotate. The driving roller 23 drives the redirecting roller 34, the roller 1 124, the roller 2 125, and the roller 3 14 to rotate through the conveyor belt. The position of the adjusting bearing 33 inside the adjusting slide 32 can be adjusted by rotating the nut on the adjusting bolt 36. The redirecting roller 34 is driven to move by adjusting the adjusting bearing 33, so that the tension of the conveyor belt can be adjusted.

[0031] A nut is rotatably connected to the surface of the screw 271. The flipping angle of the pull plate 26 is controlled by adjusting the position of the nut on the screw 271. The distance between the adjustment plate 25 and the driving roller 23 is adjusted by controlling the flipping angle of the pull plate 26. The adjustment plate 25 is mainly used to smooth the conveyor belt and prevent wrinkles.

[0032] The fixing plate 127 is fixedly connected to the main frame 11. In the initial state, the mounting plate 121 is located at the bottom position of the inner side of the main frame 11. In the normal state, the roller 124 is in a horizontal state, and the roller 2 125 is in an inclined state. When the state of the roller assembly 12 needs to be adjusted, it is only necessary to push the mounting plate 121 through the telescopic rod 128. During the process of the mounting plate 121 being pushed up, the limiting slide bar 1211 is used to ensure the stability of its up and down movement. At the same time, the return spring 122 arranged on the outside of the limiting slide bar 1211 can prevent the telescopic rod 128 from being pushed excessively. When the mounting plate 121 is pushed up, the roller 124 will be driven to move up synchronously through the mounting seat 123. At the same time, one end of the roller 2 125 will be driven to move up through the mounting seat 123. The other end of the roller 2 125 will not move due to the restriction of the connecting arm 126. In this way, the inclination angle of the roller 2 125 can be adjusted.

[0033] When using a belt conveyor, for materials with small particles and good fluidity, by adjusting the angle and height of the rollers, the conveyor belt forms a smaller slope, which helps the materials to gather stably in the center of the conveyor belt and prevents the materials from scattering during transportation. For blocky and irregularly shaped materials, appropriately increasing the angle and height of the rollers to form a larger slope can allow the materials to roll and move forward better during transportation, avoiding accumulation or jamming of the materials on the conveyor belt.

[0034] In addition, deviation is a common problem during the operation of the conveyor belt. By adjusting the inclination angle and height of the roller, the deviation of the conveyor belt can be compensated. When the conveyor belt is found to deviate to one side, the angle and height of the roller can be appropriately increased on the opposite side of the deviation, so that the conveyor belt is subjected to a corrective force toward the center and guided back to the correct running track.

[0035] In different industrial environments and conveying tasks, the requirements for belt conveyors vary. This adjustable roller design allows a conveyor to be used in a variety of working conditions. For example, when the material conveying line within the factory needs to be modified or the type of conveyed material needs to be changed, only the angle and height of the roller need to be adjusted without replacing the entire conveyor system, which greatly improves the versatility and adaptability of the equipment.

[0036] In summary, compared with the prior art, the embodiments of the present invention have the following advantages: Advantage 1: In the roller assembly 12, the mounting plate 121 is pushed by the telescopic rod 128, which can drive the roller 124 to move upward and change the inclination angle of the roller 2 125. For materials with small particles and good fluidity, the conveyor belt can form a small slope, so that the materials can be stably gathered in the center to prevent scattering; for blocky and irregularly shaped materials, the angle and height of the rollers can be appropriately increased to form a larger slope to avoid material accumulation or jamming, which can adapt to various material characteristics.

[0037] Advantage 2: When the conveyor belt deviates, the inclination angle and height of the roller 1 124 and the roller 2 125 in the roller assembly 12 can be adjusted. By increasing the angle and height of the roller on the opposite side of the deviation, the conveyor belt is subjected to a corrective force toward the center, guiding it back to the correct track, and ensuring the stable operation of the conveyor belt.

[0038] Advantage 3: In the redirection mechanism 3, the position of the adjusting bearing 33 in the adjusting slide 32 can be adjusted by rotating the nut on the adjusting bolt 36, driving the redirection roller 34 to move, thereby adjusting the tension of the conveyor belt. In the driving mechanism 2, the position of the nut on the screw 271 is adjusted to control the flip angle of the pull plate 26, thereby adjusting the distance between the adjusting plate 25 and the driving roller 23, which is used to smooth the conveyor belt, prevent wrinkles, and extend the service life of the conveyor belt.

[0039] Advantage 4: The overall adjustable roller design enables a conveyor to be used in a variety of working conditions. When the material conveying line inside the factory is modified or the type of conveyed material is changed, it is only necessary to adjust the angle and height of the roller assembly 12 without replacing the entire conveyor system, which improves the versatility and adaptability of the equipment and reduces costs.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
