A metal conductive printing film heat treatment device

The invention discloses a metal conductive printing film heat treatment device, which can improve the conductivity of a metal conductive printing film on a roll-to-roll continuous printed film, comprising a heating wheel (10) which is heated by electric power or heat medium oil and may be additionally heated outside the wheel surface by an infrared lamp tube (120) as needed; one or more heat-resistant pressure rollers (20) adjacent to the heating wheel and the surfaces may be tightly pressed against the heating wheel. The device is designed after a roll-to-roll printing unit (3) or after an oven unit (2) following the printing unit; after a metal-conducting ink (300) is printed on the film (200) by the roll-to-roll printing unit (3), the conductive printing film (400) on the film is bakedand cured by hot air, ultraviolet light or infrared rays, and then the heat treatment device (1) applies high temperature heat energy and rolling pressure to the conductive printing film on the film to be pressed.
