Description

Paper thickness adjusting mechanism of multifunctional gravure printing machine

Technical Field

The utility model belongs to the technical field of printing machine, in particular to a paper thickness adjustment mechanism for multi-functional gravure press.

Background

The intaglio printing press is characterized in that the picture and text carved on the intaglio roller are immersed in an ink tank to rotate, a doctor blade scrapes off ink on the surface of the roller, the ink in picture and text carving net holes is left, the ink in the net holes on the surface of the printing plate roller is pressed to be attached to the surface of paper which is bitten by the impression roller to form intaglio picture and text, and the intaglio ink is solidified to form color blocks or characters through irradiation of ultraviolet light. Because the depth of the cells on the surface of the gravure cylinder is larger, more ink can be stored, so that the thickness of the patterns or characters formed by gravure printing is larger, and obvious convex feeling such as lines and patterns on paper money can be achieved by touching the patterns or characters with hands. This is called the first generation gravure press, and is a gravure press which simply prints patterns, lines, and characters.

The paper thickness regulating mechanism is an important component of the gravure printing machine, the mechanism is designed in a way of being connected with a roller clutch mechanism, and the action principle is that a cylinder pushes a swing arm and a connecting rod to enable an eccentric sleeve to rotate for a certain angle, so that the circumferential surface of a printing roller is separated from or attached to the surface of an impression roller, and the printing process is interrupted or continued. As shown in fig. 1, in the first generation of intaglio printing presses, a set of worm gear and worm mechanism is designed on the swing arm, and respectively connected with two end connecting rods, the worm is rotated, the worm gear rotates, the positions of the two end connecting rods are changed, and as a result, the rotation angle of the eccentric sleeve is correspondingly changed, the center distance between the printing plate roller and the impression cylinder is changed, the center distance is opened when thick paper is printed, and the center distance is closed when thin paper is printed. The paper thickness adjusting mechanism is time-consuming and labor-consuming in operation, low in accuracy and not in line with the operation requirement of machine automation. It has become a real need to redesign a set of paper thickness adjustment mechanisms.

SUMMERY OF THE UTILITY MODEL
