The leveling machine with this structure prevents two adjacent leveling rollers from touching too close together, so the shaft diameter of the leveling rollers cannot be made too small, and the distance between the leveling rollers in the same row cannot be too small. The leveling effect of the leveling machine is closely related to the roller spacing of the same row of leveling rollers. The larger the roller spacing, the worse the leveling effect. Therefore, the existing leveling machine has the defect that the roller spacing of the same row of leveling rollers is too large, which affects the leveling effect.
