A lower leveling roller is arranged in the machine base, and multiple lower leveling rollers are arranged at intervals along the conveying direction of the metal profile. The axes of the multiple lower leveling rollers are parallel. An upper leveling roller is arranged at the bottom end of the lifting seat. The axis of the upper leveling roller is parallel to the axis of the lower leveling roller.
