Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to a self-adjusting idler roller. Background Technology

[0002] In belt conveyor systems, idlers, as key components directly supporting the conveyor belt and materials, directly affect the stability of the conveyor belt's operation. Traditional idlers are mostly passively designed, relying on the friction of the conveyor belt to drive their rotation. This passive structure inherently lacks the ability to actively correct the conveyor belt's trajectory. When the conveyor belt deviates due to uneven tension, uneven material loading, or roller installation errors, traditional idlers cannot dynamically adjust the belt, causing the deviation to persist and worsen, leading to a series of chain-reaction operational problems: 1. Belt deviation causes material spillage, resulting in material loss, environmental pollution, and increased cleanup burden and costs; 2. The edges of the conveyor belt experience abnormal wear due to continuous friction with the frame and protective covers, significantly shortening its service life; 3. A deviated conveyor belt subjects the idlers to uneven radial loads, which, over long-term operation, can cause abnormal temperature rise and lubrication failure in the idler bearings, accelerating bearing wear and even causing them to seize. If the belt misalignment is not addressed in time, it may lead to serious malfunctions such as belt tearing and drive motor overload, or even cause the entire belt conveyor system to shut down.

[0003] To address the aforementioned technical problems, the technical solution disclosed in Chinese Utility Model Patent Application No. CN202320799587.1 is an automatically adjustable belt conveyor alignment idler, comprising a self-aligning idler frame body, an electric actuator, and a deviation alarm device. The electric actuator is mounted on the cross brace of the alignment idler frame via an actuator support. The telescopic rod of the electric actuator cooperates with the self-aligning idler frame body. Deviation sensors are installed on both the left and right sides of the self-aligning idler frame body, and the deviation sensors are connected to a control box. The control box is connected to the actuator, and the deviation sensors and control box together form the deviation alarm device. This utility model has a reasonable structural design, achieving accurate and automatic alignment of the belt conveyor alignment idler, and has a long service life.

[0004] However, the above-mentioned existing technology has the following technical problems: The above-mentioned automatically adjustable belt conveyor belt alignment rollers rely on belt deviation sensors and electric actuators to actively correct the belt deviation. In actual operation, especially under harsh conditions such as high dust and high humidity, the detection part of the belt deviation sensor is easily affected by dust or humid air intrusion, causing inaccurate signal acquisition or transmission delay. This makes it impossible for the electric actuator to correct the belt deviation in time, resulting in delayed or failed correction action. Not only can it not effectively suppress the belt deviation, but it may also aggravate the deviation due to untimely response, increasing the risk of equipment failure. Utility Model Content

[0005] In view of this, it is necessary to provide a self-aligning idler roller that does not rely on external sensors and electric actuators, but achieves the correction action of the conveyor belt through the interaction of mechanical components. It can correct the conveyor belt in a timely manner even under harsh working conditions, thereby reducing the risk of equipment failure.

Each alignment component includes a support assembly, an adjustment assembly, and a triggering assembly. The support assembly includes a first support frame and a second support frame, which are sequentially fixedly mounted on the base component along the direction outward from the support component, with the second support frame being higher than the first support frame.

[0009] Preferably, each of the two support brackets has a support groove at its top, and the two ends of the horizontal roller shaft are respectively engaged in the support grooves of the two support brackets to achieve detachable installation between the two ends of the horizontal roller shaft and the two support brackets.

[0010] Preferably, the adjustment assembly includes an adjusting roller shaft and an adjusting guide roller. The adjusting guide roller is rotatably sleeved on the adjusting roller shaft, and its outer surface is used to support the corresponding side of the conveyor belt. The first end of the adjusting roller shaft is rotatably mounted on the top of the first support frame, and the second end is slidably mounted on the top of the second support frame, so that by sliding the second end of the adjusting roller shaft, the adjusting roller shaft can deflect with its first end as the axis, thereby increasing or decreasing the tilt angle of the adjusting guide roller relative to the top surface of the rectangular substrate.

[0011] Preferably, the triggering component includes a linkage and an adjusting roller. The linkage is L-shaped, with its inflection point rotatably mounted on the top of the second support frame. The first end of the linkage extends upward above the second end of the adjusting roller shaft. The top of the adjusting roller is rotatably mounted on the first end of the linkage, and its bottom maintains a preset gap with the side of the conveyor belt so that the misaligned side of the conveyor belt can push the bottom of the adjusting roller, thereby causing the linkage connected to the adjusting roller to rotate around the inflection point of the linkage. The second end of the linkage is connected to the second end of the adjusting roller shaft so that the rotating second end of the linkage can drive the second end of the adjusting roller shaft to slide.

[0012] Preferably, the first end of the adjusting roller shaft has a first connecting hole; the top of the first support frame has a first mounting hole, and the first connecting hole and the first mounting hole are connected by a pin to realize the rotational connection between the first end of the adjusting roller shaft and the first support frame.

[0013] Preferably, the second end of the adjusting roller shaft has a second connecting hole; the top of the second support frame has an arc-shaped groove and a second mounting hole, and the arc-shaped groove is closer to the horizontal roller shaft; the inflection point of the linkage has a third connecting hole, and the second end has a horizontal groove; the second connecting hole is slidably connected to the arc-shaped groove by a pin, and the horizontal groove is slidably engaged with the same pin to achieve a slidable connection between the second end of the adjusting roller shaft and the top of the second support frame, and at the same time, to achieve a slidable connection between the linkage and the second end of the adjusting roller shaft, so that the second end of the linkage can drive the adjusting roller shaft to slide; the third connecting hole and the second mounting hole are connected by a pin to achieve a rotational connection between the linkage and the top of the second support frame.

[0014] The aforementioned self-aligning idler includes a base component, a support component, and two identical alignment components. The support component and the two alignment components are all mounted on the top surface of the base component. The support component is located in the middle of the base component, and its top supports the middle of the conveyor belt. The two alignment components are symmetrically arranged on both sides of the support component. Each alignment component includes a support assembly, an adjustment assembly, and a trigger assembly. The support assembly includes a first support frame and a second support frame, which are sequentially fixed to the base component along the direction outward from the support component, with the second support frame being higher than the first support frame. The top of the adjustment assembly supports the conveyor belt. The corresponding side of the conveyor belt; the first end of the adjusting component is rotatably mounted on the top of the first support frame, and the triggering component is rotatably mounted on the top of the second support frame. Its first end, located on one side of the rotation connection point, extends above the second end of the adjusting component, so that the misaligned conveyor belt side can push the first end of the triggering component; the second end of the triggering component, located on the other side of the rotation connection point, is connected to the second end of the adjusting component, so that when the misaligned conveyor belt side can push the first end of the triggering component upwards, the triggering component rotates, and the second end of the triggering component drives the second end of the adjusting component upwards, increasing the tilt angle; thus, when the conveyor belt... When the conveyor belt deviates to one side, the edge of the conveyor belt on that side contacts and pushes the first end of the trigger component in the corresponding adjustment component, forcing the trigger component to rotate outward around its connection point with the second support frame. This rotation causes the second end of the trigger component to rotate upward, and drives the second end of the adjustment component to slide upward on the top of the second support frame. Simultaneously, because the first end of the adjustment component is rotatably mounted on the first support frame, the tilt angle of the adjustment component relative to the base component increases, thereby generating a corrective force on the deviated conveyor belt running on top of it, pointing towards the center of the top surface of the bearing component. Under the action of this corrective force, the conveyor belt... The conveyor belt moves towards the center of the top surface of the supporting component. When the conveyor belt returns to its normal position, its edge separates from the first end of the trigger component. The second end of the trigger component and the second end of the adjustment component slide downwards and reset under the action of gravity, which reduces the tilt angle of the adjustment component relative to the base component. The correction force of the adjustment component on the conveyor belt disappears, and the conveyor belt maintains normal operation under the stable support of the top surface of the supporting component. The entire correction process is achieved by mechanical linkage triggered by the conveyor belt deviation. No external sensors or electric actuators are required. It can still work reliably under harsh working conditions, effectively reducing the risk of equipment failure due to untimely correction. Attached Figure Description

Detailed Implementation

[0021] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Please refer to Figures 1 to 3 This utility model provides a self-aligning idler roller 10, including a base component 20, a bearing component 30, and two identical alignment components 40. The bearing component 30 and the two alignment components 40 are all mounted on the top surface of the base component 20. The bearing component 30 is located in the middle of the base component 20, and its top is used to support the middle of the conveyor belt 50. The two alignment components 40 are symmetrically arranged on both sides of the bearing component 30. Each alignment component 40 includes a support assembly 41, an adjustment assembly 42, and a trigger assembly 43. The support assembly 41 includes a first support frame 411 and a second support frame 412. The first support frame 411 and the second support frame 412 are sequentially fixedly mounted on the base component 20 in a direction outward from the bearing component 30, and the second support frame 412 is higher than the bearing component 30. The first support frame 411; the top of the adjusting assembly 42 is used to support the corresponding side of the conveyor belt 50; the first end of the adjusting assembly 42 is rotatably mounted on the top of the first support frame 411, and the trigger assembly 43 is rotatably mounted on the top of the second support frame 412, with its first end on one side of the rotation connection point extending above the second end of the adjusting assembly 42 so that the misaligned side of the conveyor belt 50 can push the first end of the trigger assembly; the second end of the trigger assembly 43 on the other side of the rotation connection point is connected to the second end of the adjusting assembly 42 so that when the misaligned side of the conveyor belt can push the first end of the trigger assembly 43 to lift upward, the trigger assembly 43 rotates, and the second end of the trigger assembly 43 drives the second end of the adjusting assembly 42 to lift upward, increasing the tilt angle;

[0023] Specifically, when the conveyor belt 50 deviates to one side, the edge of the conveyor belt 50 on that side contacts and pushes the first end of the trigger component 43 in the corresponding adjustment component 40, forcing the trigger component 43 to rotate outward around its connection point with the second support frame 412. The rotation of the trigger component 43 causes its second end to rotate upward, and drives the second end of the adjustment component 42 to slide upward on the top of the second support frame 412. At the same time, since the first end of the adjustment component 42 is rotatably mounted on the first support frame 411, the tilt angle of the adjustment component 42 relative to the base component 20 increases, thereby generating a corrective force on the deviated conveyor belt 50 running on top of it, pointing towards the center of the top surface of the bearing component 30. When in use, the conveyor belt 50 automatically moves towards the center of the top surface of the supporting member 30; when the conveyor belt 50 returns to the normal position, its edge separates from the first end of the trigger component 43, and the second end of the trigger component 43 and the second end of the adjusting component 42 slide downwards and reset under the action of gravity, so that the tilt angle of the adjusting component 42 relative to the base member 20 is reduced, and the correction force of the adjusting component 42 on the conveyor belt 50 disappears. The conveyor belt 50 maintains normal operation under the stable support of the top surface of the supporting member 30; the entire correction process is achieved by the mechanical linkage triggered by the deviation of the conveyor belt 50, without the need for external sensors and electric actuators, and can still work reliably under harsh working conditions, effectively reducing the risk of equipment failure due to untimely correction.

[0024] Please refer to Figure 2 Furthermore, the base component 20 includes a rectangular base plate 21. The bottom of the bearing component 30 and the bottom of the two alignment components 40 are fixedly mounted on the top surface of the rectangular base plate 21, so as to provide stable support for the bearing component 30 and the two alignment components 40 through the rectangular base plate 21. Specifically, the flat top surface of the rectangular base plate 21 ensures that the bearing component 30 and the alignment components 40 can be stably fixed on the same horizontal plane, thereby providing uniform support for the conveyor belt 50.

[0025] In this embodiment, the first support frame 411, the second support frame 412 and the bearing bracket 31 are fixed to the top surface of the rectangular substrate 21 by welding.

[0026] Please refer to Figure 2Furthermore, the supporting member 30 includes two supporting supports 31, a horizontal roller 32, and a horizontal guide roller 33. The bottom of each of the two supporting supports 31 is fixedly connected to the top surface of the rectangular base plate 21, and the two supporting supports 31 are symmetrically arranged about the width direction of the base member 20. The two ends of the horizontal roller 32 are detachably mounted on the top of the two supporting supports 31, and the horizontal guide roller 33 is rotatably sleeved on the horizontal roller 32. Its outer surface is used to stabilize the middle of the conveyor belt 50. Specifically, the two supporting supports 31 are symmetrically fixed on the rectangular base plate 21 to ensure that the installation position of the horizontal roller 32 is centered and horizontal. The horizontal guide roller 33 is rotatably sleeved on the horizontal roller 32 and can rotate freely to reduce the friction between its outer surface and the conveyor belt 50, thereby stabilizing the middle of the conveyor belt 50 and preventing unnecessary shaking or deviation of the conveyor belt 50 during normal operation.

[0027] Please refer to Figure 2 and Figure 4 Furthermore, each of the two support brackets 31 has a support groove 34 on its top, and the two ends of the horizontal roller 32 are respectively engaged in the support grooves 34 of the two support brackets 31 to achieve detachable installation between the two ends of the horizontal roller 32 and the two support brackets 31.

[0028] Please refer to Figure 2 and Figure 3 Furthermore, the adjustment assembly 42 includes an adjusting roller shaft 421 and an adjusting guide roller 422. The adjusting guide roller 422 is rotatably sleeved on the adjusting roller shaft 421, and its outer surface is used to support the corresponding side of the conveyor belt 50. The first end of the adjusting roller shaft 421 is rotatably mounted on the top of the first support frame 411, and the second end is slidably mounted on the top of the second support frame 412, so that by sliding the second end of the adjusting roller shaft 421, the adjusting roller shaft 421 can be deflected with its first end as the axis, thereby increasing or decreasing the tilt angle of the adjusting guide roller 422 relative to the top surface of the rectangular substrate 21. Specifically, through By rotatably connecting the first end of the adjusting roller shaft 421 to the top of the first support frame 411 and slidably connecting the second end of the adjusting roller shaft 421 to the top of the second support frame 412, the adjusting roller shaft 421 can deflect with its first end as the axis. When the second end of the adjusting roller shaft 421 slides upward under the drive of the trigger component 43, the tilt angle of the adjusting roller shaft 421 increases, which causes the tilt angle of the adjusting guide roller 422 to increase synchronously, thereby generating a corrective force on the side of the conveyor belt 50 pointing towards the center of the horizontal roller shaft 32, causing the misaligned conveyor belt 50 to move towards the center of the horizontal roller shaft 32.

[0029] Please refer to Figure 5Furthermore, the triggering component 43 includes a linkage 431 and an adjusting roller 432. The linkage 431 is L-shaped, and its inflection point is rotatably mounted on the top of the second support frame 412. The first end of the linkage 431 extends upward above the second end of the adjusting roller shaft 421. The top of the adjusting roller 432 is rotatably mounted on the first end of the linkage 431, and its bottom maintains a preset gap with the side of the conveyor belt 50 so that the misaligned side of the conveyor belt 50 can push the bottom of the adjusting roller 432, thereby causing the linkage 431 connected to the adjusting roller 432 to move at the inflection point of the linkage 431. The linkage 431 rotates around its axis; the second end of the linkage 431 is connected to the second end of the adjusting roller shaft 421 so that the rotating second end of the linkage 431 can drive the second end of the adjusting roller shaft 421 to slide; specifically, the "L"-shaped linkage 431 can convert the lateral movement of the adjusting roller 432 into its own rotational movement; when the edge of the conveyor belt 50 deviates and pushes the adjusting roller 432, the linkage 431 rotates around its inflection point, and its second end moves upward, thereby driving the second end of the adjusting roller shaft 421 to slide on the top of the second support frame 412, realizing the change of the tilt angle of the adjusting component 42.

[0030] In this embodiment, the top of the alignment roller 432 is rotatably connected to the first end of the linkage 431 via a pin. This connection method allows the alignment roller 432 to rotate when it receives the lateral thrust of the conveyor belt 50, thereby converting the sliding friction between the alignment roller 432 and the conveyor belt 50 into rolling friction. This reduces the frictional resistance between the alignment roller 432 and the conveyor belt 50, reduces the wear of the alignment roller 432 and the conveyor belt 50, and improves the service life of the alignment roller 432 and the conveyor belt 50.

[0031] In this embodiment, the preset gap is a reasonable range that allows the conveyor belt 50 to fluctuate normally during transportation and ensures timely triggering of the correction action. Specifically, when the conveyor belt 50 is running normally, this gap can prevent the edge of the conveyor belt 50 from contacting the bottom of the adjustment roller 432 and prevent malfunction. When the deviation of the conveyor belt 50 exceeds the normal range, the edge of the conveyor belt 50 can immediately contact and push the bottom of the adjustment roller 432, thereby initiating the correction action in a timely manner.

[0032] Please refer to Figure 2 and Figure 4 Furthermore, the first end of the eccentric roller shaft 421 has a first connecting hole; the top of the first support frame 411 has a first mounting hole 413, and the first connecting hole and the first mounting hole 413 are connected by a pin to realize the rotational connection between the first end of the eccentric roller shaft 421 and the first support frame 411.

[0033] Please refer to Figure 3 and Figure 4Furthermore, the second end of the adjusting roller shaft 421 has a second connecting hole; the top of the second support frame 412 has an arc-shaped groove 414 and a second mounting hole 415, and the arc-shaped groove 414 is closer to the horizontal roller shaft 32; the inflection point of the linkage 431 has a third connecting hole 433, and the second end has a horizontal groove 434; the second connecting hole is slidably connected to the arc-shaped groove 414 by a pin, and the horizontal groove 434 is slidably engaged with the same pin to achieve a sliding connection between the second end of the adjusting roller shaft 421 and the top of the second support frame 412, and at the same time achieve a sliding connection between the linkage 431 and the second end of the adjusting roller shaft 421, so that the second end of the linkage 431 can drive the adjusting roller shaft 421 to slide; the third connecting hole 433 and the second mounting hole 415 are connected by a pin to achieve a rotational connection between the linkage 431 and the top of the second support frame 412.

[0034] Example 1: Working process of the self-adjusting idler roller 10

[0035] 1. When one side of the conveyor belt 50 deviates, its edge will gradually approach and eventually contact the bottom of the corresponding adjusting vertical roller 432;

[0036] 2. The vertical roller 432 moves outward under the push of the edge of the misaligned conveyor belt 50. At the same time, it drives the first end of the linkage 431 to rotate outward with its inflection point as the axis, and causes the second end of the linkage 431 to rotate upward with its inflection point as the center.

[0037] 3. The second end of the adjusting roller 421 slides upward along the arc-shaped slide groove 414 under the drive of the second end of the linkage 431, which increases the tilt angle of the adjusting roller 421 relative to the top surface of the rectangular base plate 21, thereby generating a corrective force on the conveyor belt 50 pointing towards the center of the horizontal roller 32. Under the action of this corrective force, the edge of the conveyor belt 50 gradually moves towards the center of the horizontal roller 32.

[0038] 4. After the conveyor belt 50 returns to the normal position, its edge separates from the corresponding straight roller 432. The second end of the linkage 431 and the second end of the straight roller shaft 421 rotate downward under the action of gravity, so that the tilt angle of the straight roller shaft 421 relative to the top surface of the rectangular substrate 21 is restored to the initial state, thus completing the correction of the conveyor belt 50.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
