Problems solved by technology

[0004] 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

[0028] 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 comprising an ink printing head (2) comprising individually controllable ink for printing ink on a conveyed printing substrate (4), a radiation dryer and at least one light trap ) on the nozzle (11), the radiation dryer (7) includes a radiation source for generating electromagnetic radiation (13) for at least partially drying and / or hardening the ink printed on the conveyed printing substrate (4) (12), the light catcher (9) is arranged between the ink print head and the radiation dryer in such a way that the light catcher constitutes a barrier (14) for reflecting and / or scattering radiation and thus protects said ink print head from Influenced by the radiation, the light trap (9) comprises at least one duct (17), which is connected to a suction device (24) and through which polluted ambient air (18) can be sucked in. The invention advantageously makes it possible to reduce / avoid contamination of the radiation dryer.

Description

technical field [0001] The invention relates to a printing press having an ink print head, a radiation dryer and at least one light trap. Background technique [0002] 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. [0003] 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 heads, it is also known to use so-called intermediate dryers (Zwischenrockner) between these print heads, which carry out intermediate drying and / or intermediate curing of the ink (English : pinnen). Not only the end dryers but also the intermediate dryers can become contaminated, and it may be necessary to clean these dryers from time ...
