Description

Düsenkopf an Spritzvorrichtungen für Farben, Lacke und ähnliche Überzugsstoffe Zusatz zum Patent 7705299 Die Erfindung bezieht sich auf ehren Düsenkopf für Spritzvorrichtungen mit gleich-. achsig angeordneter Spritzstoff- iuid Preßluftdüse derart, daß letztere die Stoffdüse ringförmig umgibt und mit Einrichtung zur Formung des Spritzstrahls zu einem Flach-, Breit-, Lireuz- oder Sternstrahl nach Patent 705 299 versehen ist. Die Verbesserung und weitere Ausgestaltung des Düsenkopfes gemäß vorliegender Erfindung besteht darin, daß zusätzlich zu den üi Stirnflächen des Preßluftdüsen-körpers angebrachten, von der Düsenbohrung ausgehenden Formkanälen zu ihnen parallele ,ebenfalls von der Preßluftdüse ausgehende Nebenkanäle vorgesehen sind, welche zu den Hauptformk.anälen parallel geführt oder derart schräg geführt sind," daß. sie sich ihnen nähern oder sich mit ihnen vereinigen. Durch die Anordnung dieser iNebeirforml:anä.le wird der durch die Hauptkanäle gebildete Formstrahl. seitlich mehr zusammengehalten und die .außerhalb der Breite der Formkanäle aus der ringförmigen Preßluftdüse austretende Preßluft stärker in den Hauptstrom hineingeführt und daran gehindert, sich außerhalb des Formstrahls zu verbreiten. Dadurch wird zugleich der aus der Düsenmitte austretende Spritzstoff voin dien Seiten her mehr in den Hauptstrom, d. i. in den Formstrahl, hineingeführt. Zweckmäßig sind zur möglichst vollständigen Erfassung der austretenden Preßluft und des austretenden Spritzstoffes die Nebenkanäle derart ,angeordnet, däß sie etwa -tangential von der äußersten Stelle der ringf:örrnigen Preßluftdüse ausgehen. Die schon durch die Ha-uptformhanäle gemäß dem Hauptpatent erzielte Wirkur- der Verringerung der Stoftvernebehtn- wird durch Anordnung der N ebenforrnkanäle gemäß vorliegender Eifindling in verstärktem Maße erreicht. .Nozzle head on spraying devices for paints, varnishes and similar coating materials Addition to patent 7705299 The invention relates to an honor nozzle head for spraying devices with the same. axially arranged spray material iuid compressed air nozzle in such a way that the latter surrounds the material nozzle in a ring shape and is provided with a device for shaping the spray jet into a flat, broad, Lireuz or star jet according to patent 705,299. The improvement and further development of the nozzle head according to the present invention consists in the fact that, in addition to the end faces of the compressed air nozzle body, there are formed channels extending from the nozzle bore parallel to them, also extending from the compressed air nozzle, which are parallel to the main molding channels are guided or so inclined, "that. They approach them or unite with them. By the arrangement of these iNebeirforml: anä.le, the shape beam formed by the main channels is held together laterally and the outside of the width of the shape channels from the The compressed air exiting the ring-shaped compressed air nozzle is guided more strongly into the main flow and is prevented from spreading outside the mold jet. As a result, the spray substance exiting from the center of the nozzle is simultaneously fed into the main flow, i.e. into the mold jet, from the sides Capture The secondary channels of the exiting compressed air and the exiting spray material are arranged in such a way that they extend approximately tangentially from the outermost point of the annular compressed air nozzle. The effect already achieved by the main molding channels in accordance with the main patent - the reduction of the substance diffusion - is achieved to a greater extent by arranging the secondary molding channels in accordance with the present Eifindling. .

Die Zeichnung veranschaulicht ein Ausführungsheispiel der Erfindung, und zwar -zeigt :Ibb. 1 in der linken Hälfte eine Ansicht, in der rechten Hälfte einen Achsenschnitt, Abb. a einen :\chsenschnitt nach Linie:=1-B der Abh. 1 und _Ub- ; eine Ansicht der Stirnseite des Düsenkopfes.The drawing illustrates an embodiment of the invention, namely -shows: Ibb. 1 in the left half a view, in the right half an axis section, Fig. a a: \ axis section according to line: = 1-B of dep. 1 and _Ub-; a view of the face of the nozzle head.

Der Preßluftdüsenhörper 12 umschließt den mit ihre gleichachsig angeordneten. Stoff körper 11 derart. daß eine ringförmige Prof:)-luftdüsenöffnun-- 14 gebildet ist, zu welcher die Preßluft durch in die Urnfangslläche des Stoffdiisenki«r-pe3-s r 1 citlgehettet-e Kanäle 13 e an-t. In den zviindrisch oder ku-eli- -e- i , l# II l# stalteten Stirnflächen der die Düse Ciberragc)1-den VorsprVinge 16 des I'reßluftdiis.enl@örpc)-s 12 sind die nutartigen, den Spritzstrahl formenden Kanäle 15 eingearbeitet, «-elche von der Preßluftdüse 14 ausgehen und nach der Außenkante der zylindrischen oder kugeligen Stirnfläche des Düsenkörpers zu in ihrer Tiefe allmählich abnehmen.The compressed air nozzle body 12 encloses the coaxially arranged with their. Fabric body 11 such. that an annular profile is formed - air nozzle opening 14, to which the compressed air flows through channels 13 e in the circumferential surface of the material nozzle. The groove-like channels that form the spray jet are located in the cylindrical or ku-eli- -e- i , l # II l # shaped end faces of the nozzle Ciberragc) 1-the projection 16 of the stress air diis.enl@bodyc) -s 12 15 incorporated, "-which start from the compressed air nozzle 14 and gradually decrease in depth towards the outer edge of the cylindrical or spherical end face of the nozzle body.

Zu den Hauptformhanälen 15 sind beiderseits parallel laufende kleinere Nehünforrnkanäleangeordnet, die ebenfalls von der Preßluftdü:se ausgehen und hei kürzerer Länge allmählich in ihrer Tiefe sich verringern, so daß sie in die bogenförmige Stirnfläche des Düsenk.örpers l2 auslaufen. Die Nebenkanäle 1; sind etwa tan-enti.al zur Luftdüse angeordn(,t, so daß sie von denjenigen Stellen der rinförmigen Luftdüse ausgehen, die von deren Hauptformkanälen 15 a)n weitesten entfernt sind. 1)ttrclr die Nebenkanäle wird auch diejenige Preßluft erfaßt und in der Richtung der Hauptformkanäle 15 .auseinandergezogen, die etwa «regen der Entfernung vom Ha.uptformkan,al von der :ausziehenden Wirkung desselben nicht oder nicht in vollem Maße erfaßt wird. Mit dieser Preßluft wird zugleich der .aus der Stoffdii.se austretende Spritzstoff stärker in den Hauptstrom hineingeführt und gehindert, sich außerhalb des Hauptstromes zu verbreiten.Smaller ones running parallel to the main moldings 15 are on both sides Nehünforrnkanäleanarranged, which also emanate from the Preßluftdü: se and hot shorter lengths gradually decrease in depth, so that they are arched End face of the nozzle body l2. The secondary channels 1; are about tan- ti.al arranged to the air nozzle (, t, so that they come from those points of the ring-shaped air nozzle proceed, which are farthest away from the main mold channels 15 a) n. 1) ttrclr the secondary channels is also detected that compressed air and in the direction of the main mold channels 15. Pulled apart, the approximate distance from the main channel, al from the: pulling effect of the same is not or not fully grasped. With this compressed air at the same time the spray material emerging from the material nozzle is released more strongly led into the main stream and prevented from outside the main stream to spread.

Die Nebenformkanäle i; können auch schräg zu. den HauptIzanälen 15 hingefiihrt sein und sich so weit erstrecken, daß sie sich mit den Hauptkanälen vereinigen. Irr Sinne der Erfindung liegt es auch, die Hauptkanäle und Nehenkallä.le derart völlig zu ve)-schmelzen, daß die Hauptkanäle 15 an der Düsenbohrung 1 4. eine Breite besitzen, die dem Durchmesser der Preßluftdüse 14 entspricht.The secondary shape channels i; can also be slanted too. the main izan channels 15 and extend so far that they coincide with the main canals unite. It is also in the wrong sense of the invention to include the main channels and Nehenkallä.le so completely to ve) -melt that the main channels 15 at the nozzle bore 1 4. have a width which corresponds to the diameter of the compressed air nozzle 14.
