1 install the self-aligning idlers self-aligning rollers, there are many types such as intermediate shaft-style, four-link, such as vertical roll, the principle is used to block or roller in the horizontal direction blocking or transverse thrust automatic belt adjustment belt deviation of purpose that radial. General belt conveyor length is short or when the two-way running belt conveyer used this method is reasonable because shorter easier to belt conveyor deviation and no adjustment is easy. Long belt conveyor is best not to use this method, because the use of self-aligning roller will have a certain impact on the service life of the belt.
2 adjust the carrying rollers of belt conveyor's belt in the belt conveyer rollers can be adjusted when the deviation in the middle position to adjust the deviation; at the time of manufacture roller mounting hole processing growth on both sides of the hole in order to adjust. Specific method is what side belt deflection, which side of the roller belt direction moving forward, or the other side later. Belt upward direction deviation rollers, lower left, rollers, at the upper right.
3 of the tensioning adjusting belt tension adjustment adjustment of deviation of belt conveyor is a very important part. Weight tension at the top of two drum other than perpendicular to the belt length should be perpendicular to the gravity vertical, which is to ensure their level of shaft centerline. When spiral tensioning and hydraulic tensioning and tensioning rollers of two housings should at the same time the translation to ensure the belt and roller's axis perpendicular to the longitudinal direction. Specific adjustment method of belt deviation and roller adjustment are similar.
4 adjust the position-driven drum and drum-driven drum and drum belt deviation adjustment adjustment is an important link. At least 2 to 5 as a belt conveyor roller, all roller installation position must be perpendicular to the centerline of the belt conveyor length, if the deviation is too large deviation. The adjustment is similar to adjusting the rollers. Head drum belt to the deviation on the right side of the drum, the right bearing seat should be moved forward, to the left of the drum belt deviation, the left bearing seat should be moved forward, after the corresponding housings on the left can also be moved or shifted right bearing seat. Rear roller adjustment method with roller opposite the head. After repeated adjustments until the belt adjusting to a more ideal location. Adjustments before driving or drum the best accurate installation of its location.
