Rolling substrate printing machine printing and conveying mechanism

A printing transport mechanism for a roll substrate printer. The printing mechanism includes a printing unit and a printing and conveying mechanism matched with the printing machine frame. The printing mechanism is composed of a printing unit, a transfer blanket cylinder and an imprinting roller. The printing unit is arranged along the periphery of the transfer rubber cylinder. The printing unit is composed of a printing roller and a screen. The roller, the ink fountain roller, and the ink fountain constitute a printing and conveying mechanism comprising a conveying roller disposed in front of or behind a printing mechanism and a driving mechanism thereof, characterized in that a transfer rubber roller, an impression roller pair, is an intermittent contact structure, and a driving mechanism of the printing and conveying mechanism It is an intermittent drive. The utility model adopts a transfer rubber roller, an imprint roller pair, and does not need to replace the transfer rubber roller with different peripheral lengths, and can be suitable for printing jobs with different printing length specifications for different printing objects, so as to save the printing cost and improve the printing job.
