▎ 摘　　要

NOVELTY - The device has a coating printing device provided with a pressing roller, an active silica gel roller and a driving steel roller. The steel roller is immersed in a glue pool that is filled with viscous material. A metal foil (5) is arranged between the pressing roller and the steel roller. The metal foil is supported on a supporting roller. The metal foil is pressed on an upper surface of the active silicon rubber roller. A gap is formed between the active silica gel roller and the driving steel roller. A glue film is transferred to a surface of the metal foil through the pressing roller. USE - Metal foil surface graphene coating device. ADVANTAGE - The device coats on the surface of the metal foil by a material thin layer in a uniform manner implemented with sub-micron thickness so as to satisfy graphene coating thickness requirement on the metal foil, and has better adhesive force and less contact resistance between a carbon particle and the metal foil. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a metal foil surface graphene coating device in partial section. Metal foil (5) Roasting unit (12) Driving roller (23) Winding unit (41)
