Stamping climb Hook has an important role in the application of roller, roller is an important accessories and equipment.The convex section of the belt conveyor often occurs in the middle of the belt section in the direction of the arching, both the middle of the projection.And will make the belt discount, stacked after entering the redirection drum or drive drum section will exacerbate the degree of damage to the belt.The main reason for arching and discount is the tension value per unit length on the middle and outer cross-section of the belt difference is too large, so that the belt slide to the middle of the formation of arching or discount.The size of the difference between the tension value per unit length and the radius of curvature of the convex section, the roller groove angle.The larger the groove angle,the smaller the radius of curvature of the convex section, the more serious the arching and discount.When the belt conveyor groove angle reaches greater than or equal to 40 degrees, even in the belt conveyor straight section of the head or tail roller groove angle transition section can also occur arching and discount, this time should reduce the groove angle or lengthen the distance between the length of the transition section, so that the belt groove angle slow transition.For the convex section belt conveyor should be as much as possible to increase the radius of curvature of the convex section and reduce the roller groove angle under the conditions of meeting the conveying capacity.
