The upper and lower rollers of the main drive system are fully driven, driven by two motors, can be braked in an emergency, have a soft start device, have a small impact on the power grid, have reliable performance, low noise, and compact structure.
The upper and lower supporting rollers are supported by multiple rows of diameters and are arranged in a chess pattern with the work roller. The bottom is equipped with an integral inclined iron adjustment mechanism. The shape of the upper and lower leveling rollers can be adjusted by manual fine-tuning to maintain the rigidity of the work roller and level the wave of the thin plate. When bending, convex, and concave buckling deformation, it is necessary to use the backing roll to change the convexity of the work roll, and manually adjust the opening amount and inclination angle of the upper leveling roll, which can easily adapt to the correction requirements of wave bending and scoop-shaped plates.
