The invention provides slitting equipment and a double-rolling-shaft unloading device thereof. The double-rolling-shaft unloading device comprises a movable frame and further comprises an upper rolling shaft unloading assembly and a lower rolling shaft unloading assembly which are mounted on the movable frame, can both move vertically and comprise unloading arms horizontally extending to an upper rolling shaft and a lower rolling shaft from the obverse side correspondingly. The unloading arms can be matched with external equipment to complete unloading. The two unloading assemblies can horizontally move to get close to/away from the upper rolling shaft and the lower rolling shaft from the obverse side simultaneously so as to bear and synchronously move roll materials on the upper rolling shaft and the lower rolling shaft away. The unloading arm of the lower rolling shaft unloading assembly can be turned over and folded so as to avoid vertical movement of the upper rolling shaft unloading assembly, and thus the unloading arm of the upper rolling shaft unloading assembly can move downwards to the preset position to be matched with the external equipment for receiving material rolls to complete unloading. The slitting equipment and the double-rolling-shaft unloading device thereof are high in efficiency and can reduce material roll damage in material roll unloading.
