The running deviation of conveyor belt is the most common fault of belt conveyor, and its timely and accurate treatment is the guarantee of its safe and stable operation. The phenomenon and reason of running deviation are many, and it is necessary to adopt different adjustment methods according to different running deviation phenomenon and reason to solve the problem effectively. Based on years of practice, this paper analyzes and describes the causes and treatment of such faults from the perspective of users.
The axial line of the head driving roller or tail is not perpendicular to the center line of the conveyor belt, causing the conveyor belt to run sideways at the head roller or tail. Roller deflection, firmness, on either side of the conveyor belt in the cylinder along the width direction of the traction Fq are inconsistent, increasing or decreasing trend, so you can make the belt attached a movement in the direction of decreasing Fy, cause the conveyor belt running deviation to loose side, known as the "running loose not tight. The adjustment method is: for cylinder head such as the right side of the conveyor belt to the roller running deviation, is on the right side of the bearing should be moving forward, P send to cylinder on the left side of the wandering, is on the left side of the bearing should be moving forward, can also be on the left side of the corresponding bearing seat back or on the right side of bearing seat back. The tail drum adjustment method is the opposite of the head roller. After repeated adjustment until the conveyor belt is tuned to an ideal position. It is best to install the position before adjusting the drive or turning the drum.
The diameter of the outer surface of the roller is different, and the conveyor belt will run sideways to the larger side. The so-called "running big does not run small". The traction Fq of PVC conveyors produces a moving component with a large diameter side. Under the action of ffy, the conveyor belt generates deviation. In this case, the solution is to clean the surface of the drum, and the processing error and the uneven wear will be replaced.
