Offset printer with enhanced drying system

Abstract

The invention discloses an offset printer with an enhanced drying system. The offset printer comprises a front paper conveying roller, a middle paper conveying roller, a coating disc, a coating disc roller, a measurement anilox roller, a glue coating roller, an impression roller, a paper collecting roller, a multi-layer paper collecting platform and the drying system; the drying system comprises a hot air drying device arranged in the paper collecting roller, and a UV drying device arranged between the paper collecting roller and the multi-layer paper collecting platform; the hot air drying device is a cross flow fan, and a shell of the hot air drying device is provided with a plurality of rows of air outlets; the UV drying device comprises a base, a cable and uniformly-distributed UVLED lamps; and a monitor and an adjuster are connected to the UV drying device. According to the offset printer with the enhanced drying system, drying is conducted through two modes of the hot air drying device and the UV drying device, the hot air drying device can reduce paper deformation while conducts drying, the UV drying device generates little heat and do not produce ozone, and in addition, the lamps can be turned on or off instantly; and the working efficiency is improved, and meanwhile, electric energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of printing machinery, in particular to an offset printing machine with an enhanced drying system. Background technique [0002] The offset printing machine is a kind of lithographic printing machine. When printing, the printed image and text are first printed from the printing plate to the rubber cylinder, and then transferred to the paper by the rubber cylinder. Offset printing machines can be divided into sheet-fed offset printing machines and web offset printing machines according to different feeding methods; according to the number of printing colors completed in one pass, they can be divided into single-color, two-color, four-color and multi-color printing machines; The largest paper format can be divided into small offset printing machines, six-fold, four-fold, folio and full-sheet printing machines, and there is also a double-sided printing machine that can print on both sides at the same time with ...
