The resultant force of the external force on the tape in the width direction of the tape is not zero or caused by uneven tensile stress perpendicular to the width of the tape. Since there are many factors that cause the tape deviation, it is necessary to solve the deviation of the tape from the aspects of the design, manufacturing, installation and debugging, use and maintenance of the conveyor. For example, the tightness of the two sides of the tape is different, and the height of the two sides of the tape is different. Similarly, if the roller bracket and other devices are not installed on the vertical section of the belt running direction, it will cause the belt to deviate.
Concrete mixing plant belt deviation solution:
1. When the tape is running, if it runs off the same side under no load and heavy load, it means that the tightness of the two sides of the tape is not the same, adjust the tightness of the left and right; if the tape runs off the left and right without a fixed direction, then It means that the tape is loose and the tensioning mechanism should be adjusted.
2. If the tape runs off the roller, it means that the roller is not installed horizontally, the roller is moving axially, or one end of the roller is at the front and the other is at the back. At this time, the levelness and parallelism of the roller should be corrected.
3. If the tape always deviates to one side when there is no load, move the roller support on the deviated side by 1-2cm in the running direction of the tape, or move the other roller support (or rack) appropriately Heighten.
4. If there is material sticking to the part of the roller or the supporting roller, the diameter of the part will increase, which will increase the tension of the tape and cause deviation. Adhesive materials should be cleaned up in time.
5. If the tape does not deviate when there is no load, but always deviates to one side under heavy load, it means that the tape has been eccentrically loaded. The position of the receiving hopper or the tape conveyor should be adjusted so that the tape is evenly loaded to prevent deviation.
6. If the edges of the tape are severely worn or the seams of the tape are not parallel, the tension on both sides of the tape will be inconsistent. The tape should be re-dressed or replaced.
7. If several sets of self-aligning rollers (flat rollers or grooved rollers) are installed on the conveyor, the deviation of the tape can be automatically corrected. For example: when the tape runs off and rubs against the small stop roller on one side, the bracket on that side should be moved forward along the running direction of the tape, and the other side should move relatively backward. At this time, the tape will move backward. The stop roller moves on one side until it returns to the normal position.
8. If the tape always deviates to one side, a limit vertical roller can be installed on the rack on the deviated side; this way, on the one hand, the tape can be forced to reset, and on the other hand, the vertical roller can reduce the tension of the tape on the deviated side. To move the tape to the other side.
