Driving drum head or tail bend pulley axis is not perpendicular to the centerline of the conveyor belt patterns wholesale, causing the conveyor belt at the head or tail bend drum roll at the deviation. When deflection rollers, conveyor rollers tightness in both sides of the inconsistency, along the width direction of traction Fq also suffered inconsistent, as increasing or decreasing trend, which would make the conveyor belt attached to the descending direction of a moving force Fy led to the loose side of the conveyor belt deviation, the so-called "run do not run loose tight." The adjustment method is: as for the head drum roller conveyor deviation to the right, then to the right of the bearing seat should be moved forward pattern conveyor manufacturing plant, conveyor roller deviation to the left, then on the left side bearing should be moved forward, also corresponding to the left rear bearing bearing on the right-shift or shift. Rear roller adjustment methods and the head drum opposite. After repeated adjustments until the conveyor transferred to an ideal position. The best and accurate installation drive before adjusting its position or bend pulley drum outer surface machining error, sticky material or wear caused by uneven diameter sizes, the conveyor will deviation to the side of the larger diameter. So-called "big run do not run small." Its force situation shown in Figure IV: Fq traction belt moves to produce a large-diameter side of the force Fy pattern conveyor belt, in the component Fy role conveyor shifted. In this case, the solution is to clean the surface of the drum stick materials, processing errors and uneven wear to be replaced down the reworked package of plastic processing production pattern conveyor | Conveyor Belt | Central Asia, Central Asia and the whole of the industrial belt from Qingdao entire industrial belt Limited.
