Double-module multifunctional roll-to-roll micro-nano imprinting system

The invention discloses a double-module multifunctional roll-to-roll micro-nano imprinting system. The problem that in the prior art, a roll-to-roll imprinting device is single in function is solved,and the double-module multifunctional roll-to-roll micro-nano imprinting system has different functions of single-face hot rolling, single-face ultraviolet rolling, double-face hot/ultraviolet mixed rolling, double-face ultraviolet rolling and the like. According to the technical scheme, the double-module multifunctional roll-to-roll micro-nano imprinting system comprises an unwinding unit, a pretreatment unit, a first module, a second module and a winding unit which are sequentially arranged, wherein the first module is a hot rolling and ultraviolet rolling shared module, a gradient hydraulicsystem is adopted for providing different magnitudes of pressure, single-face hot rolling and single-face ultraviolet rolling can be achieved through the first module, and a functional micro-nano structure array is machined o
