Description

Cleaning equipment for notebook printing roller

Technical Field

The invention relates to the technical field of printing roller cleaning, in particular to a cleaning device for a notebook printing roller.

Background

In a lithographic printing machine, when printing a printed sheet, printing ink may remain on the surface of a printing roller, and when the printing is repeated, problems such as uneven printing ink, uneven depth and the like are caused, and the printing roller needs to be cleaned, otherwise, the next printing is inconvenient, and the labor intensity and the working time of workers are increased. If the printing press has a conventional inking unit with inking zones, the above-described alternating action can be counteracted by adjusting the inking zones. By correspondingly adjusting the ink zones outside the specification width, the ratio between printing ink and dampening solution can be influenced in such a way that disturbing effects are suppressed. However, this is not possible when the printing press has a screen ink device without ink zones. The anilox roller of such an anilox ink set delivers a constant ink quantity over its entire roller length, i.e. also over the full width of the printed sheet to be printed, the size of which depends on the so-called fill volume of the small grooves or channels of the anilox roller anilox. The ratio between printing ink and dampening solution present here is therefore influenced only by the change in the amount of dampening solution, for which purpose the dampening unit has to be designed accordingly, which increases the production and equipment costs. To this end, we propose a cleaning device for a notebook printing roller.
