Description

Technical Field

[0001] This utility model belongs to the field of waste treatment, and specifically relates to an anti-deviation idler roller assembly. Background Technology

[0002] Currently, belt conveyors are widely used in waste disposal. These conveying devices use a belt as both the traction and load-bearing component, relying on the friction between the drive roller and the belt to transmit traction. However, in transportation projects, uneven material distribution or uneven stress during operation often causes belt misalignment. When misalignment occurs, the belt wears severely and may even seize up. Belt misalignment significantly affects the belt's lifespan and the stability of the conveyor's operation; therefore, effective control of belt misalignment is crucial. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects and provide an anti-deviation idler group that can automatically adjust belt deviation and make the belt that is running off-track self-correct.

[0004] The purpose of this utility model is achieved through the following technical solution: an anti-deviation idler assembly, characterized in that: it includes a conical idler, a short idler, and a long idler; the long idler and idler bracket are arranged at intervals along the direction of the conveyor belt; the idler shaft inside the long idler is equipped with a bearing; the two ends of the idler shaft are mounted on the idler bracket; the side idler bracket is inclined toward the idler bracket; the idler shaft inside the conical idler and the short idler is equipped with a bearing; the conical idler and the short idler are coaxially and symmetrically mounted on the side idler brackets on both sides of the idler bracket; the surface of the conical idler is a concave arc surface; the short idler is closer to the long idler; the bottom of the conical idler is away from the long idler; a belt is placed on the long idler; the two sides of the belt are placed on the short idler and the conical idler on both sides.

[0005] The angle between the side roller support and the horizontal direction is 25°-40°.

[0006] The beneficial effects of this utility model are:

[0007] 1. Using conical idlers, the concave arc surface of the conical idler generates a force on the belt pointing towards the center of the conveyor belt, which increases with the increase of the curvature of the generatrix. This effectively prevents the belt from continuing to run off-center and can also push the belt to move towards the center of the conveyor belt, so that the belt returns to its normal position. This achieves automatic adjustment of belt deviation, allowing the belt to self-correct when it is running off-center.

[0008] 2. It utilizes appropriate principles, has a simple composition, and achieves good results. Attached Figure Description

[0012] 1-Idler bracket, 2-Conical idler, 3-Short idler, 4-Belt, 5-Long idler, 6-Side idler bracket. Detailed Implementation

[0013] Example: As shown in the figure, an anti-deviation idler assembly includes a conical idler 2, a short idler 3, and a long idler 5. The long idler 5 and the idler bracket 1 are arranged at different intervals of different sizes along the belt conveyor body according to different material requirements. The idler shaft inside the long idler 5 is equipped with bearings, and the two ends of the idler shaft are mounted on the idler bracket 1. The side idler bracket 6 is inclined towards the idler bracket 1, and the angle between the side idler bracket 6 and the horizontal direction is 25°-40°. The idler shaft inside the conical idler 2 and the short idler 3 is equipped with bearings. The conical idler 2 and the short idler 3 are coaxially and symmetrically mounted on the side idler brackets 6 on both sides of the idler bracket 1. The surface of the conical idler 2 is a concave arc surface. The short idler 3 is closer to the long idler 1, and the bottom of the conical idler 2 is away from the long idler 5. A belt 4 is placed on the long idler 5, and the two sides of the belt 4 are placed on the short idler 3 and the conical idler 2 on both sides.

[0014] Working principle: The tapered idler sleeve 2 uses the component force generated on the belt 4 by the tapered idler sleeve 2 in the direction of the belt conveyor center to prevent the belt from continuing to run off-center and push the belt to return to its original position, thereby achieving the purpose of preventing belt from running off-center.

[0015] The working process of this device is as follows: When belt 4 deviates to one side due to uneven force, that is, when the edge of belt 4 moves upward along the curved generatrix of the conical idler sleeve 2 on this side, the component force generated by the conical idler sleeve 2 on belt 4 pointing towards the center of the belt conveyor increases with the increase of the curvature of the generatrix. This component force not only effectively prevents belt 4 from continuing to deviate, but also pushes belt 4 to move towards the center of the belt conveyor, so that belt 4 returns to its normal position, thereby achieving the purpose of preventing belt deviation.
