Self-aligning supporting roller mechanism for belt

Abstract

The invention relates to a self-aligning supporting roller mechanism for a belt. The self-aligning supporting roller mechanism comprises a fixed support, an eccentric disc, a movable support and connecting rods, wherein the eccentric disc is arranged in the middle in the fixed support in a rotating mode; supporting rods are vertically arranged at the two ends of the front of the fixed support, deflection stop wheels are arranged at the lower ends of the supporting rods in a rolling mode, when the belt located between the deflection stop wheels is deflected, external force is exerted on the deflection stop wheels by the deflected belt, the eccentric disc rotates and then drives the movable support to rotate under the effect of the external force, and the deflected belt can be adjusted along with rotation of the movable support. The self-aligning supporting roller mechanism has the beneficial effects that when the belt is deflected due to the load change, the working condition change and the steering change in the transportation process of a belt conveyor, the deflected belt can be adjusted and reset immediately by the self-aligning supporting roller mechanism for the belt, manual adjustment is not needed, and the belt is prevented from being deflected.

Description

technical field [0001] The invention relates to the field of belt transport mechanical equipment manufacturing, in particular to a belt self-aligning idler mechanism. Background technique [0002] The belt conveyor machinery industry is developing very fast and is widely used for long-distance transportation. However, due to the influence of factors such as manufacturing, installation, and incorrect joints, the deviation of the belt conveyor is inevitable. At present, there are many methods for correcting the deviation of the conveyor belt. The most common and effective way for the machine is to use self-aligning rollers. The mechanical adjustment methods for belt deviation are as follows: [0003] 1. The principle of self-aligning roller [0004] When the centerline of the idler roller is perpendicular to the centerline of the conveyor belt, take any contact point M between the conveyor belt and the idler roller, and the linear velocity V of the conveyor belt at this poin...

[0015] Since the upper beam of the friction self-aligning roller is connected to the lower beam through the rotary shaft, there is also a phenomenon of poor rotation in actual operation. In addition, the friction force of the friction disc is adjusted by a spring. Due to various errors in manufacturing and installation The existence of the friction disc is not ideal, thus losing the advantages of the friction disc

[0016] 3. Because many users are not good at using the current belt-aligning idler mechanism, they adopt local methods. The following idler adopts a zigzag bracket and is manually adjusted. However, during the transportation of the belt (especially the long belt), the working conditions Changes occur at any time, and the belt deviation is unstable, resulting in belt damage from time to time due to manual adjustment; remove the upper idler bolts and manually adjust, and also cause belt damage from time to time.
