Problems solved by technology

[0005] Here, the problem can arise in the prior art that removing the parts to be cleaned from the machine is very laborious and thus takes a lot of time
In contrast, problems can arise when cleaning dryers in machines: cleaning may not be sufficient, or advantageous cleaning methods (such as ultrasonic cleaning) may not be performed at all
These problems can also lead to other problems: for example, the failure of the dryer due to an insufficient cleaning process

Embodiment Construction

[0029] figure 1 Shown is a side view of a preferred embodiment of a printing machine 1, in particular an ink printing machine 1, with a plurality of ink printing heads 2: one ink printing head 2a for printing white ink (zinc white) ( or a printing mechanism with such an ink print head 2a), and a plurality of ink print heads 2b for printing black ink and / or colored ink (such as the known color K CMY OGV) (or with such an ink print head 2b printing units), the ink printing heads 2b are arranged downstream of the ink printing heads 2a in the conveying direction 3 of the printing material 4 (in particular a web), for example made of paper or plastic film. The ink printing heads 2 are mounted so that they can move up and down (by means of drives not shown) at least in the side wall 5 on the operating side of the machine 1 . The side wall 5 has an opening 6 . The ink printing heads preferably each comprise a nozzle plate with a plurality of individually actuatable nozzles for eje...

Abstract

The invention relates to a printing machine with an inkjet printing head, a radiation drier and at least one light trap, the inkjet printing head (2) including separately controllable nozzles (11) forapplying ink to a transported printing material (4); the radiation drier (7) including radiation sources (12) for generating electromagnetic radiation (13) to at least partly dry or cure the appliedink on the transported printing material (4); the at least one light trap (9) being disposed between the inkjet printing head and the radiation drier in such a way that the light trap forms a barrier(14) for reflected and / or scattered radiation, thus protecting the inkjet printing head from radiation. The light trap (9) includes at least one channel (17) connected to an aspiration device (24) foraspirating contaminated ambient air (18) through the channel. The printing machine can advantageously reduce or prevent contamination of the radiation drier.

Description

[0001] This application is a divisional application of an invention patent application with an application date of July 18, 2019, an application number of 201910649695.9, and an invention title of "Printing Machine Equipped with an Ink Printing Head, a Radiation Dryer, and At Least One Light Capturer". technical field [0002] The invention relates to a printing press having the features of claim 1 , having an ink print head, a radiation dryer and at least one light trap. Background technique [0003] The invention belongs to the technical field of the graphics industry and in this context in particular the printing of inks and the drying and / or curing of the printed inks. [0004] When drying and / or hardening inks, it is known to use end dryers, which end-dry the ink after printing and before post-press processing (for example by evaporating water) and / or (for example by polymerization) ) to achieve final hardening. Furthermore, in the case of printing with several print h...
