Description
Technical Field
[0001] This utility model relates to the field of belt conveyor technology, and in particular to a damping idler roller for belt conveyors. Background Technology
[0002] Belt conveyors, also known as belt conveyors, are mechanical devices that continuously transport materials. They are widely used in industries such as coal, mining, ports, power, building materials, chemicals, and metallurgy. Belt conveyors transport materials by rotating multiple damping idlers below. The function of the damping idlers is to absorb vibration, buffer impact, reduce noise, and extend service life during the operation of the conveyor belt.
[0003] Damping idlers are typically installed on belt conveyors, below the conveyor belt. During operation, they absorb material impacts and equipment vibrations, providing flexible support for the conveyor belt. However, existing damping idler structures generally lack auxiliary support structures. During high-speed rotation, the idlers are prone to vertical or radial swaying, which can lead to uneven tension distribution of the conveyor belt and material dispersion, thereby reducing the working efficiency of the belt conveyor. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-3This utility model provides an embodiment of a damping idler for a belt conveyor, comprising: a base 1; a mounting frame 2 for mounting the damping idler; multiple mounting plates 3, which are fixed to the top of the mounting frame 2 from left to right; multiple rotating shafts 4 and multiple damping idler bodies 5, the multiple rotating shafts 4 engaging with the multiple mounting plates 3, and the multiple damping idler bodies 5 rotatably connected to the outside of the multiple rotating shafts 4; multiple L-shaped plates 6, which are fixedly connected to the outer sides of the mounting frame 2; multiple lead screws 7 and multiple knobs 8, the multiple lead screws 7 being threaded into the inside of the multiple L-shaped plates 6, and the multiple knobs 8 being fixedly connected to the bottom of the multiple lead screws 7; multiple arc-shaped plates 9 and multiple auxiliary wheels. 10. Multiple arc-shaped plates 9 are rotatably connected to the top of multiple lead screws 7, and multiple auxiliary wheels 10 are rotatably connected to the outer periphery of multiple arc-shaped plates 9; and a disassembly and assembly assembly is used to install and disassemble the damping roller. The multiple auxiliary wheels 10 are all made of rubber, which effectively absorbs the vibration and impact force generated by contact and impact. Multiple L-shaped plates 6 are all fixedly connected to the inside of telescopic rods 11, and the top of multiple telescopic rods 11 is fixedly connected to the outside of multiple arc-shaped plates 9. The telescopic rods 11 serve to assist the movement of the arc-shaped plates 9. The mounting plate 3 has a mounting groove 19 in the middle, and the rotating shaft 4 is set inside the mounting groove 19. The mounting groove 19 facilitates the installation of the rotating shaft 4.
[0033] Specifically, when supporting the damping roller body 5, firstly, the knob 8 needs to be operated. Turning the knob 8 will cause the lead screw 7, which is fixedly connected to its exterior, to rotate. The rotation of the lead screw 7 causes the arc-shaped plate 9, which is rotatably connected at the top, to move laterally. During the movement of the arc-shaped plate 9, it causes multiple auxiliary wheels 10, which are evenly installed around its exterior, to move laterally in sync. As the arc-shaped plate 9 moves, the auxiliary wheels 10 gradually approach and eventually contact the outer surface of the damping roller body 5. Once it is confirmed that the auxiliary wheels 10 are in full contact with the damping roller body 5, the knob 8 can be stopped from being turned further to maintain the current support position. In order to achieve stable support for the entire idler body, the other support points can be set one by one according to the above steps. By repeatedly rotating the knob 8, driving the lead screw 7, moving the arc plate 9, and pushing the auxiliary wheel 10 to fit against the outside of the damping idler body 5, a multi-point stable support structure can be formed. Through the above structural design, multiple auxiliary wheels 10 form stable contact with the outer surface of the damping idler body 5, and successfully achieve comprehensive support for the damping idler body 5. This can effectively prevent the idler from shaking, swaying, or other unstable phenomena during high-speed rotation, and ensure the balance and consistency of the idler in actual operation.
[0034] Reference Figures 3-4The assembly includes a mounting cavity 12, which is located inside the mounting plates 3 on the left and right sides. A slider 13 is slidably connected inside the mounting cavity 12. A crossbar 14 is fixedly connected to the top of the slider 13. A limit rod 15 is fixedly connected to the left side of the slider 13, and a spring 20 is fixedly connected to the right side of the slider 13. A through hole 17 is provided on the upper part of the mounting plate 3. The crossbar 14 is slidably connected inside the through hole 17. The through hole 17 facilitates the movement of the crossbar 14. A through hole 28 is provided inside the mounting plate 3. The limit rod 15 is slidably connected inside the through hole 28. The through hole 28 facilitates the movement of the limit rod 15. A slot 16 is provided on the left side of the mounting plate 3. The limit rod 15 is inserted into the slot 16, which limits and fixes the rotating shaft 4.
[0035] Specifically, when it is necessary to disassemble the damping roller body 5, firstly, the crossbar 14 should be moved so that it drives the slider 13 fixedly connected to the bottom to move inside the mounting cavity 12. Simultaneously, as the slider 13 moves, it also drives the limiting rod 15, which is fixedly connected to its outer left side, to move parallel. At the same time, as the slider 13 pushes inward, the spring 20 fixedly installed on its right side will be compressed, putting the spring 20 under stress. After pushing the slider 13 to a certain position, the limiting rod 15 will gradually disengage from the slot 16 provided on the left side inside the mounting plate 3. At this point, the rotating shaft 4, together with the damping roller body 5, can be smoothly removed from the mounting plate 3 as a whole. The internal parts of plate 3 are removed, completing the disassembly operation. This process does not require additional tools, simplifying the cumbersome steps of traditional disassembly. When reinstalling, first align the rotating shaft 4 with the pre-set mounting groove 19 in the middle of the mounting plate 3 and firmly embed it into the groove. Then, release the previously moved crossbar 14. Under the rebound force of the spring 20, the slider 13 returns to its original position, thereby driving the limit rod 15 to re-insert into the slot 16 set on the left side of the mounting plate 3, thus completing the locking and positioning function. Through the design structure, the operator does not need to rely on complicated tools. They can simply push or release the crossbar 14 to complete the installation or disassembly operation, effectively saving time and effort.
[0036] Working principle: When supporting the damping idler body 5, firstly, turn the knob 8 to rotate the externally fixed lead screw 7. The rotation of the lead screw 7 causes the top-rotating arc plate 9 to move laterally. When the arc plate 9 moves, it also causes the auxiliary wheels 10 installed around the outside to move synchronously, so that the auxiliary wheels 10 contact the outside of the damping idler body 5. Then, stop turning the knob 8. Repeat the above steps for other support methods. By having the auxiliary wheels 10 contact the outside of the damping idler body 5, the support of the damping idler can be completed. This facilitates the support of the damping idler, effectively reduces the swaying or wobble of the idler when rotating at high speed, and keeps the idler in a balanced state during operation, thereby improving the stability of the idler operation.
[0037] When it is necessary to disassemble the damping roller body 5, firstly, the moving crossbar 14 moves the bottom-fixed slider 13 inside the mounting cavity 12. During the movement of the slider 13, the limiting rod 15 fixed on the outer left side moves with it. At the same time, when the slider 13 moves, it squeezes the spring 20 fixed on the outer right side, causing the spring 20 to deform under force. Then, when the limiting rod 15 disengages from the slot 16 opened on the left side inside the mounting plate 3, the rotating shaft 4 and the damping roller body 5 can be removed from the inside of the mounting plate 3. During installation, the rotating shaft 4 is locked in the mounting groove 19 opened in the middle of the mounting plate 3. Then, the crossbar 14 is released, and under the reaction force of the spring 20, the limiting rod 15 is inserted into the slot 16, thus completing the installation of the damping roller. This makes it easy to install and disassemble the damping roller, and the operation is simple, convenient, time-saving, and labor-saving, thereby improving the efficiency of damping roller installation and disassembly.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
