Distance adjusting mechanism and photogravure press thereof

Abstract

The invention discloses a distance adjusting mechanism and a photogravure press thereof. The photogravure press of the distance adjusting mechanism comprises an outer shell. The outer shell is internally provided with an inner printing cavity and a rear processing cavity. The rear processing cavity is internally provided with a baking plate, fourth conveying rollers, a blowing box, a sucking box and fifth conveying rollers. The baking plate is internally provided with heating wires. The blowing box is used for blowing the two end faces of a printing stock. The sucking box is used for sucking air in the rear processing cavity. The two fourth conveying rollers and the two fifth conveying rollers form two pairs respectively, and each fourth conveying roller and each fifth conveying roller arearranged on an upper roller shaft or a lower roller shaft correspondingly. The air inlet end of the blowing box communicates with an exhausting joint of an antistatic device, an air inlet joint of the antistatic device communicates with a dust removing exhaust pipe of the dust removing device, a first air passing pipe and a second air passing pipe of the antistatic device communicates with an exhaust port of a booster pump, and the dust removing exhaust pipe further communicates with an air inlet of the booster pump. The dust removing air inlet pipe of the dust removing device communicates with an exhaust port of an air pump, and an air inlet of the air pump communicates with the interior of the sucking box.

Description

technical field [0001] The invention relates to printing technology, in particular to a pitch-adjusting mechanism and a gravure printing machine thereof. 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 t...

Problems solved by technology

Although the filtering effect of this method is very good, the resistance generated by it is relatively large, which results in relatively high energy consumption, and the filter element needs to be repaired and replaced regularly, which greatly increases the cost of use and maintenance.
