Problems solved by technology

[0002] The general transfer rate of the ink in the gravure mesh of the gravure rotary printing machine is 1 / 2, that is, 1 / 2 remains on the printing plate, the viscosity of the ink is high, and the drying speed of the ink is too fast, so that the ink dries on the anilox network The holes, or pattern mesh holes have been blocked by dry agglomeration, and the new ink cannot be completely redissolved, and it will pile up on the printed matter in a large area, and the pattern text will be smeared. , repeated many times in this way, the ink transfer rate decreases, and finally becomes a problem of plate blocking

Abstract

The invention discloses a combined type intaglio wheel rotary printing machine. The structure of the rotary printing machine comprises printing paper conveying mechanisms, a conveying roller, a printing structure, supporting bases, winding rollers and a printer body. The supporting bases are vertically fixed to the two horizontal sides of the top end face of the printer body. The printing structure is arranged between the two supporting bases. The conveying roller is installed on the bottom of the printing structure. The printing paper conveying mechanisms and the winding rollers are installedon the front sides and the rear sides of the supporting bases correspondingly. The winding rollers and the printing paper conveying mechanisms are movably matched. The printing structure is composedof an ink groove, an ink conveying roller, an intaglio drum and a wetting clearer. The ink groove is installed below one side of the intaglio drum. The ink conveying roller is arranged in the ink groove. The ink conveying roller and the intaglio drum are movably attached. The wetting clearer is arranged at the other end, opposite to the ink conveying roller, of the intaglio drum. According to therotary printing machine, by means of a water distributing device, after the intaglio drum rolls for one third, water directly acts into the intaglio drum and flushes a notch of the intaglio drum, inkis gradually softened, or ink in the notch of the intaglio drum is removed.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a combined gravure rotary printing machine. Background technique [0002] The general transfer rate of the ink in the gravure mesh of the gravure rotary printing machine is 1 / 2, that is, 1 / 2 remains on the printing plate, the viscosity of the ink is high, and the drying speed of the ink is too fast, so that the ink dries on the anilox network The holes, or pattern mesh holes have been blocked by dry agglomeration, and the new ink cannot be completely redissolved, and it will pile up on the printed matter in a large area, and the pattern text will be smeared. , Repeated this many times, the ink transfer rate decreased, and finally became a problem of plate blocking. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention is realized through the following technical solutions: a combined gravure rotary printing machine, the structure...
