▎ 摘　　要

NOVELTY - Device comprises base (1) with shaft bracket (13) that is fixedly connected to an upper surface side of the base. The inner side of the bracket is connected with a first extruding roller (11) and a second pressing roller (12) through a shaft. The surface of the first extruding roller is in close contact with the second pressing roller. The upper side of the locating plate is fixedly connected with a side plate (21), and the side plate is fixedly connected with a side plate. USE - Device for optimizing high-quality monolithic graphene film (claimed). ADVANTAGE - The device enables to provide effective protection to the graphene film, and improves the production efficiency. DETAILED DESCRIPTION - Device comprises base (1) with shaft bracket (13) that is fixedly connected to an upper surface side of the base. The inner side of the bracket is connected with a first extruding roller (11) and a second pressing roller (12) through a shaft. The surface of the first extruding roller is in close contact with the second pressing roller. The upper side of the locating plate is fixedly connected with a side plate (21), and the side plate is fixedly connected with a side plate. The inner side of the panel is provided with a circular hole. The inner side of the circular hole is slidably fitted with a round bar fixedly connect with extrusion and cutter rod that is fixedly connected with a spring. The upper end of the spring is fixed with the lower surface of the connecting plate. The inner ends of the sipe are welded with cutting blades. The inner lower end of the heat insulating box is fixedly connected with a first motor and the heat insulation. The upper end of the box is provided with a sealing ring in which the position of the port of the first motor that is connected with the blade through the seal ring. An air filter is fixedly connected with an inner end of the heating cylinder, and a shaft base is fixedly connected to an inner side of the heating cylinder, and the heating shaft. The inside of the shaft seat is fitted with a ceramic tube, and the surface of the ceramic tube is wound with an electric heating wire. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene film optimizing device. Base (1) First extruding roller (11) Second pressing roller (12) Shaft bracket (13) Side plate (21)
