Description

Zum flächigen Auftragen von Fluiden insbesondere Klebstoffe kommen u.A. auch Sprühdüsen zum Einsatz.Adhesives, in particular, are used for the flat application of fluids. spray nozzles are also used.

Hierbei haben sich auch außenmischende Düsen bewährt.External mixing nozzles have also proven their worth here.

Normal tritt bei diesen Düsen das Fluid (Klebstoff) aus einer Düsenbohrung aus .Diese Bohrung ist von einem Ringspalt oder ringförmig angeordneten Bohrungen umgeben aus denen mit hoher Geschwindigkeit Gas, üblicherweise Luft ausströmt und das Fluid in Tröpfchen oder hochviskose Klebstoffe zu Fäden zerreißt.With these nozzles, the fluid (adhesive) normally emerges from a nozzle bore. This bore is surrounded by an annular gap or ring-shaped bores from which gas, usually air, flows out at high speed and the fluid tears into threads in droplets or highly viscous adhesive.

  • 1 Das erfindungsgemäße Nutblech (1) legt nun Fluid (2) und Gasaustritt (3) in Reihe und beliebiger Zahl nebeneinander Die Nuten sind gegenüberliegend ineinander verzahnt eingearbeitet so das von einer Seite des Nutblechs Fluid (4) und der anderen Seite Gas (5) zugeführt wird. Das ausströmende Fluid wird hiervon zwei beidseitig liegenden Gasströmen fächerförmig zerrissen. So entsteht ein linienförmiger Auftrag wie bei einer Schlitzdüse nur als kontaktloser Auftrag. 1 The grooved plate according to the invention ( 1 ) now puts fluid ( 2 ) and gas outlet ( 3 ) in a row and any number next to each other The grooves are interlocked opposite one another so that fluid ( 4th ) and the other side gas ( 5 ) is supplied. The outflowing fluid is torn apart in a fan shape by two gas streams lying on both sides. This creates a line-like application like a slot nozzle only as a contactless application.
  • 2 Das erfindungsgemäße Nutblech (4) kann auch bei Schlitzdüsen mit Maskenblech (1) als Umbausatz in Verbindung mit einer Luftverteilerleiste (2) nachgerüstet werden. Bei Verarbeitung von Hotmelt muss die Luft(3) vorgeheißt werden. 2 The grooved plate according to the invention ( 4th ) can also be used with slot nozzles with masking plate ( 1 ) as a conversion kit in connection with an air distribution strip ( 2 ) can be retrofitted. When processing hot melt, the air ( 3 ) are given.

Dadurch gekennzeichnet ,dass der Werkstoff Stahl, Messing ,Alu oder für kalte Fluide auch PTFE,Peek oder anderer Kunststoff sein kann. This is characterized by the fact that the material can be steel, brass, aluminum or, for cold fluids, PTFE, PEEK or other plastic. Dadurch gekennzeichnet,dass die Nuten gefräst,erodiert,gelasert oder geätzt sind- Characterized in that the grooves are milled, eroded, Video- lasered or etched Dadurch gekennzeichnet,dass die Nuten beidseitig im Verbund gegeneinander vom Versorgungskanal bis Düsenaustritt verlaufen This is characterized by the fact that the grooves run against one another on both sides in a composite from the supply channel to the nozzle outlet Dadurch gekennzeichnet,dass die Nutbreite und Tiefe das heißt der Querschnitt der Nut dem Fließverhalten (Viskosität) des zu verarbeitenden Fluids angepasst werden kann. Characterized in that the groove width and depth that is the cross section of the groove the flow behavior (viscosity) of the fluid to be processed can be adjusted.
