Abstract

The invention relates to an application device (V) for applying an application agent to a component, preferably for applying a coat to a motor-vehicle body component. The application device (V) comprises a printhead (100) for preferably serially and/or continuously applying the application agent, wherein the printhead (100) has: a nozzle plate (1), at least one nozzle (2) in the nozzle plate (1) for dispensing the application agent, at least one valve element (9) movable relative to the nozzle plate (1) for controlling the dispensing of the application agent by means of the at least one nozzle(2), wherein the at least one movable valve element (9) closes the at least one nozzle (2) in a closed position and opens the at least one nozzle in an open position, and at least one drive (A) for moving the at least one valve element (9). The application device (V) is characterized in particular in that the application device comprises at least one temperature-control device (T1-T8) for reducing heating of the at least one drive (A) during the application of the application agent.

Description

technical field [0001] The invention relates to an application device for applying a coating medium to components, preferably for applying paint to motor vehicle body components, comprising a printing head for preferably serially and / or Or apply the coating medium without overspray. Background technique [0002] Atomizers (such as rotary atomizers, air mixing atomizers, airless atomizers, etc.) are commonly used as application equipment for the continuous spraying of automotive body parts, but these have limited application efficiency The disadvantage is that only a part of the applied paint is deposited on the part to be coated, while the rest of the applied paint has to be disposed of as so-called overspray. [0003] With regard to the general prior art, reference is first made to DE 20 2013 101 134 U1, DE 10 2010 019 612 A1 and DE 197 43 804 A1. [0004] US 9,108,424 B2 discloses a drop-on-demand valve jet printer whose working principle is based on the use of electric ...
