Abstract

The invention discloses a gravure printing machine, which comprises a casing and a distance adjusting mechanism. The casing is provided with a printing inner chamber and a post-processing chamber. The post-processing chamber is provided with a baking plate, a fourth conveying roller, an air blowing box and box, the fifth conveying roller, and the heating wire built into the baking plate; the air blowing box is used to blow air to both ends of the substrate; the suction box is used to suck the air in the post-processing chamber; two fourth conveying rollers, two Each of the fifth conveying rollers forms a pair, and each of the fourth and fifth conveying rollers is installed on the upper roller shaft or the lower roller shaft respectively; the air inlet end of the air blowing box is connected with the exhaust joint of the static removal device , the air intake joint of the static removal device is connected with the dust removal exhaust pipe of the dust removal device, and the first and second air passages of the static removal device are respectively connected with the exhaust port of the booster pump, and the dust removal exhaust pipe is also connected with the booster pump. The air inlet of the pump is connected; the dust removal inlet pipe of the dust removal device is connected with the exhaust port of the air pump, and the air inlet of the air pump is connected with the inside of the suction box.

Description

technical field [0001] The invention relates to printing technology, in particular to a gravure printing machine. Background technique [0002] The gravure printing machine is a commonly used printing equipment at present, and its structure is relatively simple, which can be applied to large-scale printing requirements. The current gravure printing machine mainly adopts a printing roller with an intaglio pattern, and the pattern is printed on the substrate by dipping the printing roller in ink. After using the gravure printing machine for a long time, the inventor found that the current gravure printing machine mainly has the following defects: [0003] 1. The requirement for the thickness of the substrate is fixed, mainly because the gap between the conveying rollers on both sides of the printed matter is fixed. Therefore, when facing substrates of different thicknesses, different printing machines need to be used for printing. On the one hand, this increases the cost of ...
