The invention discloses a roll-to-roll printing electronic ink-jet processing platform based on an air floating roller support. According to the processing platform, an rolling mechanism (1), a tension adjusting mechanism (2), a static air floating roller (4), a tension detecting mechanism (5) and a unrolling mechanism (6) are mounted on the same bottom plate (7C) from right to left successively.A nozzle mounting mechanism is fixed above the static air floating roller. The processing platform replaces a conventional rotating roller by the static air floating roller, generates a gas film between a porous cylinder body and a flexible film, separates the film from the porous cylinder body, eliminates the position error of the film caused by the processing error and assembly error of the rotating drum, and improves the printing accuracy of printing electronic ink-jet printing.
