This machine is a leveling machine with two rows which are upper and lower shaft rollers. It is mainly composed of a frame, upper roller row seat, lower roller row seat, transmission mechanism, adjustment mechanism and other components. During work, the reduction gearbox is driven by the motor, and the transmission roller shaft in the upper and lower roller row seats is driven by the chain transmission to realize the leveling function of the busbar. The power in the transmission chain is transmitted to the leveling roller shafts in the upper and lower roller rows through the upper and lower chains so that the roller shafts of the upper and lower roller rows become power rollers. In this way, the leveling machine works stably.
