Deep roller bending device of uncoiler with dust collection function

Technical Field

The utility model is mainly used for a flat trimming production line of a hot rolling finishing area, and particularly relates to a deep roller bending device of an uncoiler with a dust collection function.

Background

The deep bending roll device of the traditional hot rolling finishing line uncoiler has the function of giving a back bending force to a strip steel head so as to eliminate the convexity formed by the strip steel during uncoiling and facilitate strip threading; meanwhile, the iron scale of the strip steel is broken by bending the strip steel by utilizing the brittleness of the surface layer of the iron scale. In the production process, the broken iron scale particles and powder need to be cleaned in time, and if the iron scale particles and the powder are not cleaned in time, the iron scale particles and the powder can turn to the pinch roll along with the strip steel inlet and turn to the straightening machine behind the pinch roll. These scale particles and powders are pressed into the strip, affecting the quality of the hot rolled coil surface.

At present, the iron scale particles and powder are cleaned by mainly arranging a blower beside a machine for blowing, so that the iron scale is blown away. However, the iron scales cannot be completely blown away by the blower, and the iron scales are still brought to the surface of the roller in the production process to cause indentation on the surface of the strip steel. In addition, the blown iron scale can pollute the environment, and some fine iron scale particles can diffuse into the air along with the air flow, so that the respiratory tract of field operators can be damaged.
