Description

In der Klebstoffauftragstechnik sind zum beschichten,kaschieren Schlitzdüsen bekannt.
Um einen gleichmäßigen Auftrag (Schichtstärke) über die gesamte Breite zu erzielen werde verschiedene Techniken eingesetzt.
zB. Kleiderbügelform, Fächeraufteilung oder großer Stauraum vor dem Düsenaustrittschlitz.In adhesive application technology, slot nozzles are known for coating, laminating.
In order to achieve a uniform application (layer thickness) over the entire width, various techniques are used.
e.g. Hanger shape, compartment division or large storage space in front of the nozzle outlet slot.

Die hier erfindungsgemäß vorgestellte Technik soll das strömende Fluid gleichrichten und Turbolenzen bremsen (STRÖMUNGSVERGLEICHMÄSSIGER)The technology presented here according to the invention is intended to rectify the flowing fluid and brake turbulence (FLOW COMPARISON).

Funktionsbeschreibung:Function description:

Fluid strömt unter Druck durch Eingangsbohrung 1 in Stauraum 2 Fluid flows under pressure through the inlet bore 1 in storage space 2nd

Zum Düsenaustritt hin wird das Fluid durch eine Struktur 3 (STRÖMUNGSVERGLEICHMÄSSIGER) mit vielen kleinen kommunizierenden Hohlräumen gepresst.The fluid flows through a structure towards the nozzle outlet 3rd (FLOW COMPARISON) pressed with many small communicating cavities.

Hierfür kann man offenporige Metall oder Keramikschäume, auch Sintermetalle verwenden.Open-pore metal or ceramic foams, including sintered metals, can be used for this.

Über die Austrittkammer 4 strömt das Fluid zum Düsenschlitz 5 und tritt dort über die gesamte Breite gleichmäßig aus.Via the outlet chamber 4th the fluid flows to the nozzle slot 5 and exits there evenly across the entire width.
