Device of thermal lamination in advance of film

The utility model relates to a laminating device especially relates to a device of thermal lamination in advance of film. Including the support frame, set up a preheating roller on the support frame,the 2nd preheating roller and thermal lamination roller in advance, preheating roller heating the first film, the 2nd preheating roller heating second film, the first film and second film add thermallamination in thermal lamination roller department in advance and form composite membrane layer. The device is at the other rubber roll that all is provided with of each preheating roller, and the effect of rubber roll at first is that to make film and preheating roller laminate inseparabler, and also with the air escape between film and the preheating roller, it is inhomogeneous to avoid the filmto be heated, influences preheating effect in addition. In addition the utility model discloses in, do not produce unsettledly after the heating of film as far as possible, avoid the air temperaturelow and take away the heat o
