Embodiment Construction

[0027] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0028] A data-based positioning method for printing rubber roller cutting, the method comprising the following steps:

[0029] Step 1. Coincide the midline of the printing paper in the axial direction with the midline of the ink form roller, the ink spreader and the ink transfer roller in the axial direction to determine the working area, and mark the work area, wherein the ink form roller, the ink spreader to The working part of the ink transfer roller increases gradually;

[0030] Step 2, according to the axial length of the image and text area on the printing plate, determine the reserved area and the cutting area in the working part on the ink form roller, the ink equalizing roller and the ink transfer roller, and mark the line;

[0031] Step 3, cutting and removing the glue layer outside the working part of the ink form roller, ink equalizing roll...

Abstract

The invention discloses a cutting datamation locating method for printing rubber rollers. The method comprises the following steps that 1, the axial dimensions of work parts of the rubber rollers are determined according to the specification of printing paper, lines are marked, and the work parts from the inking roller and the ink distributing roller to the ink transfer roller are gradually enlarged; 2, according to the axial length of a graphic area on a printing plate, reserved areas and cutting areas in the work parts on the rubber rollers are determined, and lines are marked; 3, the parts, except the work parts of the inking roller, the ink distributing roller and the ink transfer roller, of rubber layers and the parts, of the cutting areas, of the rubber layers are cut and removed; and 4, lines are marked, and a database is set up. A dimension determining method for the complete set of rubber rollers required when a printing machine table product is replaced is converted from a traditional machine-on 'rubbing method' into calculation 'datamation'. The progressiveness of the method is mainly embodied in that when a past product is replaced, the process method that various tasks are conducted term by term in a in a 'series connection mode' is converted into the process method that the various tasks are conducted simultaneously in a 'parallel connection mode'. The invention further discloses a cutting and line-marking device for the printing rubber rollers.

Description

technical field [0001] The invention relates to the field of printing, in particular to a data-based cutting and positioning method for printing rubber rollers and a cutting and scribing device for printing rubber rollers. Background technique [0002] The printing rubber roller is the main component of the inking system of the offset printing machine. Its function is to transfer and apply ink to the printing plate, and its quality directly affects the quality of the product. During the working process, the printing rubber roller is a vulnerable part, and there are often phenomena such as wear and tear, and it can be repaired when the printing quality is not high. For important products such as banknotes and securities, once the printing rubber roller is damaged, a new rubber roller is directly replaced. [0003] In order to print out the set pattern, it is necessary to scribe and cut the surface of the complete cylindrical rubber roller every time a new rubber roller is r...
