The conveyor belt is the key equipment of the conveyor system, and its safe and stable operation directly affects the production operation. The deviation of the conveyor belt is the most common fault of the belt conveyor, and its timely and accurate treatment is the guarantee of its safe and stable operation. There are many phenomena and reasons for deviation. It is necessary to adopt different adjustment methods according to different deviations and causes to solve the problem effectively. This article is based on years of field practice, from the user's point of view, using mechanical principles to analyze and explain the causes and treatment of such failures.
1. The axis of the head drive roller or the tail redirection drum is not perpendicular to the conveyor center line, causing the conveyor belt to run off at the head roller or the tail redirection drum. When the drum is skewed, the tightness of the conveyor belt on both sides of the drum is inconsistent, and the traction force Fq received in the width direction is inconsistent, increasing or decreasing, so that the conveyor belt is attached with a moving force Fy in the decreasing direction. , causing the conveyor belt to go to the loose side, the so-called "running loose does not run tight." The adjustment method is as follows: for the head roller, such as the conveyor belt, to the right side of the drum, the right bearing housing should move forward, and the conveyor belt runs away from the left side of the drum, then the left bearing housing should be forward Move, corresponding to the left bearing housing back or the right bearing housing back. The tail roller is adjusted in the opposite way to the head roller. After repeated adjustments until the conveyor belt is adjusted to a better position. It is best to install the position accurately before adjusting the drive or reversing the drum.
