Head or tail bend pulley driven roller conveyor axis is not perpendicular to the center line, 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 polyester conveyor belt, which would make the conveyor belt to attach a descending direction The moving force Fy, lead to the loose side of the conveyor belt 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, the roller conveyor deviation to the left, the left side of the bearing seat should move forward move, can also be the corresponding left side 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 to produce a large-diameter side of the mobile component Fy, in the role of the food component Fy conveyor, 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 conveyor longitudinal tear ⑴ life reasons. Conveyor save poor, suffer the sun, rain and flooding suffered long run will involve the preparation of the core layer of the main conveyor belt, pulling the rope rust; long-term use tape prepared interlayer combination of fatigue, off shares will result in broken wires longitudinal tear phenomenon tape machine running. ⑵ transport bulky materials. Illegal use of tape machine transport large, long strips of material, material transport due to accidental encounter jamming, resulting in a longitudinal tear through the tape. ⑶ system into a hard piece of iron or gangue. Reprinted tape discharge point is an essential link in the transport conveyor belt buckle, when the transport system into a long iron or a hard piece of waste rock and whereabouts at the time of impact penetration reprint jammed tape or tape wear, causing tear split tape. ⑷ conveyor deviation. Belt Conveyor commissioning, maintenance is not good, substantial deviation conveyor belt, suffered rolled, hanging card, and then tear with accident occurred. ⑸ small piece of hard material stuck in the belt surface and the chute or sweeper of the question, gradually grinding through conveyor belt tear resulting polyester conveyor belt, conveyor Blue Village, Central Asia, Central Asia and the whole industrial belts from Qingdao entire industrial belt Limited The company offers.
