Abstract

The invention relates to the technical field of roll paper intaglio printing press accessories, in particular to a novel double-faced drying box for a roll paper intaglio printing press. The novel double-faced drying box for the roll paper intaglio printing press comprises a middle wall panel. An upper spacer and a lower spacer are mounted on the middle wall panel, wherein the upper spacer and thelower spacer are distributed vertically. A middle box is fixed to the upper spacer and the lower spacer and only internally provided with a guiding roll set. A left box is arranged at the left side of the middle box, and a right box is arranged at the right side of the middle box. The left box and the right box are each provided with an air inlet and an air outlet. The novel double-faced drying box is simple in structure, reasonable in design, easy and convenient to operate and good in drying effect; the middle box is fixed to the upper space and the lower spacer of a rack in a manner that the middle box is in a saddle shape. The air inlets are connected with a hot air drying system, and the air outlets are connected with an exhaust gas discharging system.

Description

technical field [0001] The invention relates to the technical field of accessories for a web gravure printing machine, in particular to a novel double-sided drying box for a web gravure printing machine. Background technique [0002] Gravure printing, referred to as gravure printing, is one of the four printing methods. Gravure printing is a direct printing method. It imprints the ink contained in the gravure pits directly onto the substrate. The shades of the printed picture are determined by the size and depth of the pits. If the pits are deep , it contains more ink, and the ink layer left on the substrate after embossing is thicker; on the contrary, if the pit is shallower, the amount of ink contained is less, and the ink layer left on the substrate after embossing Just thinner. The printing plate of gravure printing is composed of pits corresponding to the original graphics and the surface of the printing plate. When printing, the ink is filled into the pits, and the ...
