The technical scheme of the invention is as follows:

an ink-jet digital printer is composed of a machine frame with a print platform, a longitudinal moving unit consisting of longitudinal guide track on said machine frame, a transverse beam supporter sliding along said longitudinal guide track, and a longitudinal moving actuator for driving said transverse beam supporter to move along said longitudinal guide track, a transverse moving unit consisting of transverse beam, transverse guide track, ink car and transverse moving actuator, and a trigger unit consisting of trigger rod, trigger sensor and eccentric sensor.

The method comprises the steps of laying a printing stock on the upper surface of a printing platform during ink jet printing of a printing machine, driving a transverse moving device (comprising an ink car) to move along a longitudinal guide rail through a longitudinal moving execution mechanism, moving a nozzle group on the ink car to a designated position according to printing requirements, driving the nozzle group on the ink car to move along a transverse guide rail through the transverse moving device, simultaneously ejecting ink from nozzles of the nozzle group to be sprayed and printed on the printing stock under the control of an ink jet controller, wherein in the process, an anti-collision touch rod of the anti-collision device also moves along with the ink car , if the printing stock is arched and wrinkled, or other foreign matters exist on the upper surface of the printing platform, the anti-collision touch rod touches the arched or wrinkled printing stock, or other foreign matters on the upper surface of the printing platform, so that the anti-collision touch rod rotates around a horizontal rotating shaft and separates the swinging rod from a limiting block, at the moment, the horizontal rotating shaft drives a triggering eccentric block to rotate and trigger a triggering sensor to control the ink jet type digital printing ink car to stop moving along the transverse guide rail, thereby effectively solving the problem that the printing stock.

Therefore, when the ink vehicle is driven to move back and forth along the transverse guide rail by the transverse moving actuating mechanism, no matter which direction the ink vehicle moves transversely, if the printing stock is arched or wrinkled or other foreign matters are on the upper surface of the printing platform, the anti-collision touch rod touches the arched or wrinkled printing stock or other foreign matters on the upper surface of the printing platform before the ink vehicle, so that the anti-collision touch rod rotates around the horizontal rotating shaft, the trigger eccentric block rotates and the trigger sensor is triggered, the ink vehicle is controlled by the ink jet type digital printer to stop moving along the transverse guide rail, and the step is further performed to effectively solve the problem that the printing stock or other foreign matters are involved in the nozzle to cause the damage of the nozzle of the ink vehicle.
