Interpretation of redirection device of flat belt conveyor :
The belt conveyor uses a reversing roller or a reversing roller group to change the moving direction of the conveyor belt.
Redirection rollers can be used to change the direction of the conveyor belt by 180 °, 90 °, or <45 °. The reversing roller or vertical hammer-type tension roller generally arranged at the rear changes the conveyor belt to 180 °, and the roller above the vertical weight tensioning device changes to 90 °, and the direction below 45 ° is generally used to increase the conveyor belt. The wrap angle with the drive drum.
The diameter of the redirecting drum is 250, 315, 400, 500, 630, 800, 1000mm and other specifications. When selected, it can match the diameter of the driving drum. When turning to 180 °, its diameter can be one stop smaller than the diameter of the transmission drum. When turning to 90 ° or 45 °, it can be appropriately reduced by 1-2 steps as the turning angle decreases.
Reversing rollers are a number of supporting rollers arranged along the arc of the required radius. It is used in places where the radius of curvature of the conveyor belt is large, or in the grooved roller section. Can maintain grooved cross section.
When the conveyor belt passes through the convex arc section, the elongation of both sides of the conveyor belt is greater than the center due to the influence of the groove angle of the idler roller. In order to reduce the stress of the tape, the curvature radius of the convex arc segment should be as large as possible, and the elongation of the fabric core tape is generally 0.8%.
The flat belt conveyor should ensure the reliability and usefulness of the cleaner during operation, and there should be no material on the return belt. If the above content cannot be guaranteed, the material on the return belt will enter the driving roller or redirect the roller with the return belt. The belt will be damaged by the material and the vulcanized rubber layer on the surface of the roller will be damaged. Breaks will appear on the belt, reducing the belt's service life.
