The starting end of the oil baffle is located on the discharge side of the upper work roll cylinder and corresponds to the bottom of the upper work roll cylinder, and the terminal end extends in the rotation direction of the upper work roll cylinder to the top of the upper work roll cylinder, so that the cold rolling oil splashed from the upper work roll cylinder is blocked by the oil baffle on the corresponding side and drips along the starting end of the oil baffle to the collecting device matched with the cold rolling equipment, thereby recycling the cold rolling oil and avoiding environmental pollution caused by the cold rolling oil.
