The invention discloses a high-speed single concave printing machine. Its structure includes a paper feeder, a printing box, a drying mechanism and a paper delivery machine. The paper feeder is connected to the left side of the printing box, and the right side of the printing box is connected to the drying mechanism. The right side of the drying mechanism is connected to the delivery machine. The printing box includes an impression cylinder, an upper support shaft, a printing plate cylinder, a doctor blade, a lower support shaft, an ink tank, a frame, a synchronizing device, a substrate, A support and a pressing device, a printing plate cylinder is arranged under the imprinting cylinder, a substrate is arranged between the impressing cylinder and the printing plate cylinder, and the lower part of the printing plate cylinder is immersed in the ink tank. The beneficial effect of the present invention is: through the connecting bar The replacement of the drive belt can make the impression cylinder and the plate cylinder move synchronously all the time, avoid the occurrence of slippage, improve the printing quality, and the printing material can be compressed by the pressing device to prevent loosening, and the movable disc is adjusted on the chute It can adapt to substrates of different thicknesses and improve the use value.
Description
technical field [0001] The invention relates to the field of printing machines, in particular to a high-speed single gravure printing machine. Background technique [0002] There are four printing methods for printing machines, among which gravure printing is to fill the ink into the depression of the gravure, scrape off the remaining ink with a doctor blade, and then print on the substrate by embossing. [0003] In the current gravure printing, because the impression cylinder and the gravure cylinder roll with each other to drive the substrate to move, when one of them slips or there is a differential speed, the substrate will be pulled, making the printed font elongated or the border blurred, affecting printing the quality of. Contents of the invention [0004] The main purpose of the present invention is to overcome the deficiencies of the prior art and provide a high-speed single gravure printing machine. [0005] The present invention adopts the following technical ...
