Abstract: The present disclosure relates to the technical field of printing, and provides a digital printing press. The digital printing press includes a frame, and an unwinder, a driver, an inkjet printer, a curer and a winder that are arranged on the frame, where the driver drives a substrate to move from the unwinder to the winder along a substrate path, the inkjet printer and the curer are arranged above a printing segment of the substrate path, the printing segment of the substrate path is in the shape of an arch, and the arch bends toward the inkjet printer and the curer. The UV light from the curer can be reflected by the substrate to a position other than the inkjet printer as a result of the arched printing segment. UV light is prevented from entering the inkjet printer's nozzle, extending the inkjet printer's service life.

Abstract: The present invention has disclosed an automatic quality inspection machine and a control method thereof, which relates to the technical field of inspection devices. The machine comprises a frame, an unrolling device provided at the frame, an inspection mechanism, a button operating platform for removing a defective roll-type printing product, a slitting mechanism, a main controller, a display device, and a rolling device. The rolling device includes a first rolling mechanism and a second rolling mechanism, the first rolling mechanism includes a first rolling airshaft and a first outgoing feed roller corresponding to the first rolling airshaft; the second rolling mechanism includes a second rolling airshaft and a second outgoing feed roller corresponding to the second rolling airshaft.

Abstract: The present invention provide a full-servo label inspection machine and a control method thereof; the machine includes a frame, the frame is provided with an unrolling mechanism, a rolling mechanism, a visual inspection mechanism, a label removal mechanism, and a label replacement mechanism. In the label removal mechanism, when the paper pressing roller is at the label removal position, it presses the material to be inspected downwards to form an angle of less than 180° with the rear end of a label removal plate. After a defective label on the material to be inspected passes the label removal plate, a front end of the defective label curls up and eventually sticks onto the label removal paper. The present invention allows fully automation of the removal and replacement of labels, achieving high inspection efficiency and accuracy.

Abstract: The present invention has disclosed a multifunctional automatic quality inspection machine and a control method thereof. The machine comprises a frame, an unrolling device provided at the frame, an inspection mechanism, a button operating platform, a slitting mechanism, a main controller, a display device, and a rolling device; a paper movement route is provided between the unrolling device and the rolling device; the inspection mechanism and the display device are respectively electrically connected to the main controller; the rolling device includes a first rolling airshaft, a second rolling airshaft, and a rolling drive device; the first rolling airshaft and the second rolling airshaft are provided on the rolling drive device; the first rolling airshaft and the second rolling airshaft swap their positions via the rolling drive device. The machine has a number of functions including automatic unrolling, high inspection precision, discharging waste materials, splitting and quick rolling.
