How to adjust the conveyor belt

<p>The <a href="https://www.uliflex.com/product-industrial-belt" rel="noopener noreferrer" target="_blank"><a href="https://www.uliflex.com/product-industrial-belt" target="_blank">conveyer belt</a></a> is the key equipment of the conveyer system, its safe and stable operation directly affects the production operation. Deflection of conveyor belt is the most common fault of conveyor belt, timely and accurate treatment is the guarantee of its safe and stable operation. There are various phenomena and causes of deviation, so different adjustment methods should be adopted according to different phenomena and causes of deviation to effectively solve the problem. Based on many years of field practice, this paper analyzes and explains the causes and treatment methods of such failures from the perspective of users using mechanical principles.</p><p><br></p><p><br></p><p>1. The verticality error between the installation position of the support roller set and the center line of the conveyor belt is large, resulting in the conveyor belt deviating from the loading area. As the belt moves forward, the idler wheels are subjected to a forward pull force Fq. The traction force is decomposed into the component force Fz and the transverse component force Fc to rotate the guide wheel. This horizontal component causes the guide wheel to move axial. The fixed roller of the support cannot move axially, which will inevitably produce a counterforce Fy on the conveyor belt, which will cause the conveyor belt to move to the other side, resulting in flexion.</p><p><br></p><p><br></p><p>After the force exerted by the charge roller set at the time of installation tilt is understood, it is not difficult to understand the cause of the conveyor belt deviation, and the adjustment method is also clear.</p><p><br></p><p><br></p><p>The first method is to process long holes on both sides of the roller group during the manufacturing process to facilitate adjustment. The specific adjustment method is shown in Figure 2. The method is which side of the belt is deflected, which side of the roller assembly moves forward in the forward direction of the belt, or the other side moves in the forward direction of the belt. Behind. As shown in Figure 2, the bottom of the drum group should be moved to the left, while the top of the drum group should be moved to the right.</p><p><br></p><p><br></p><p>The second method is to install a set of self-aligning rollers. There are many types of self-aligning roller groups, such as intermediate shaft type, four link type, vertical roller type and so on. The principle is to prevent or prevent the rotation of the drum in the horizontal plane. Or generate a side thrust to make the belt automatically centripetal, in order to achieve the purpose of adjusting the deflection of the belt, the force is the same as the deflection force of the support roller set. In general, it is reasonable to use this method when the total length of the conveyor is short or when the conveyor is running in two directions. The reason is that shorter belts are easier to run and less easy to adjust. It is best not to use this method on the long belt conveyor, because the use of automatic self-aligning roller group will have a certain impact on the service life of the conveyor belt.</p>
