Damage treatment method of welding roller frame

When the welded roller frame is manufactured, the rollers and welded parts are round, and all the rollers are the same length, and the axes are parallel. Then the influence of the automatic sprocket weldment is the force under the weldment, and the reaction force of the rolling sprocket to the weldment, which is what we call the circumferential force. That is, if the weldment is rotated around its axis, its axis will not move up and down. If the axes of the welded roller frame are in the same plane, the distance between the rollers has no effect on the speed of the shaft's up and down movement. Therefore, if there is any error in the time division of the idler equipment, it is not allowed. If the number of rollers deflected at the same angle is large, the up and down movement speed of the welding shaft will be faster and faster. There is also a focal point for the left and right sides of the weldment, which also changes the speed of the axes.
