Description
Rotierender Zweikomponentensprühkopf für elektrostatische Lackiervorrichtungen Es ist bereits ein rotierender Zweikompoientensprühkopf für elektrostatische Lackiervorricltungen vorgeschlagen worden, der aus zwei mit desselben Drehzahl rotierenden Sprühglocken besteh, von denen die eine gleichachsig innerhalb der aideren angeordnet ist und jede eine Zuführung für eile der Komponenten aufweist.Rotating two-component spray head for electrostatic painting devices It is already a rotating two-component spray head for electrostatic painting devices has been proposed that consists of two spray bells rotating at the same speed exist, of which one is arranged coaxially within the aideren and each has a feed for some of the components.
Es wurde nun gefunden, daß die Vereiniguig der beiden Lackkomponenten wesentlich verbesset werden kann, wenn erfindungsgemäß der äußere Iprühkörper glockenförmig und der innere Sprühlörper als Sprühscheibe ausgebildet ist, wobei die Frühscheibe ungefähr in der Ebene der Sprühkan-, der Sprühglocke liegt.It has now been found that the union of the two paint components can be significantly improved if, according to the invention, the outer spray body is bell-shaped and the inner spray body is designed as a spray disk, the early disk lies approximately in the plane of the Sprühkan-, the spray bell.
Die günstige Wirkung beruht auf den untershiedlichen Kantenrichtungen der äußeren Sprühjocke und der inneren Sprühscheibe, wodurch die va der Scheibe abgesprühten Tröpfchen sich anfäglich radial nach außen, also auf die von der Sprühjocke hauptsächlich in Achsrichtung abgesprühten Töpfchen hin, bewegen.The favorable effect is based on the different edge directions the outer spray jock and the inner spray disc, whereby the va of the disc The sprayed droplets initially move radially outwards, i.e. onto those of the spray jock mainly in the axial direction of the sprayed pots, move.
Hierbei ist es vorteilhaft, wenn die Sprühseeibe und die Sprühglocke axial gegeneinander eittellbar sind.It is advantageous if the spray disc and the spray bell are axially eittellbar against each other.
Bei einem bekannten elektrostatischen Spritgerät für einfache Lacke ist innerhalb eines glockenlrmigen Zerstäuberkörpers konzentrisch ein zviter, wesentlich kleinerer glockenförmiger Zerstäberkörper angeordnet. Die beiden Zerstäuberllrper sollen mit verschiedener Drehzahl, der größereangsamer als der kleinere, jedoch so schnell umlafen, daß die Farbe allein durch die Fliehkräfte zeräubt wird. Die elektrostatischen Feldkräfte sind ir der Hauptsache nur dazu da, um den Farbteilcherden Weg zu dem lackierenden Gegenstand vorzusoreiben. Der Zweck dieser Doppelglockenanordnunist, die freie Fläche in der Mitte des von einer ei en Glocke erzeugten kranzförmigen Farbniedersc gs auf dem zu lackierenden Gegenstand gleichfallänit Farbe auszufüllen oder wenigstens zu verkleiner Für die Zweikomponentenlackierung ist esekannt, einen einzigen scheibenförmigen Zerstäiirkörper zu verwenden, dem die Komponentenietrennt auf beiden Seiten zugeführt werden. Ilse Anordnung ist nur für den Betrieb mit lotrecier Scheibenachse und Führung der Werkstücke umie Scheibe herum verwendbar.In a known electrostatic sprayer for simple paints is a concentric zviter, essential within a bell-shaped atomizer body arranged smaller bell-shaped atomizer body. The two atomizers should run at different speeds, the larger one slower than the smaller one, however run around so fast that the paint is atomized by centrifugal forces alone. the electrostatic field forces are mainly there only to earth the color particles Rubbing away to the object to be painted. The purpose of this double bell arrangement is the free area in the middle of the wreath-like shape created by an egg bell Color lowersc gs on the object to be painted also to be filled in with color or at least too small For the two-component painting it is known to to use a single disc-shaped atomizer body, which separates the components fed on both sides. Ilse arrangement is only for operation with lotrecier Disc axis and guidance of the workpieces around the disc can be used.
In der Zeichnung ist ein Ausführungsbeispiel er Erfindung im Schnitt dargestellt.In the drawing, an embodiment of the invention is in section shown.
Die Sprühglocke 1 mit einer messerartigen Kamt weist eine Hohlwelle 3 auf, die mit Bohrungen 4 @-sehen ist, durch die die aus dem Rohr 5 ausfließe Lackkomponente auf die Innenseite der Glocke 1 gelangt. Mit geringem Abstand hinter der Ebene der Sprühkante 2 ist eine Sprühscheibe 6 mit gleichfalls messerartiger Sprühkante 7 angeordnet, deren hohle, vorn offene Welle 8 fest mit der Hohlwelle 3 der Glocke 1 verbunden ist. Beide Hohlwellen 3 und 8 können mit Gewinde versehen sein, so daß eine axiale Einstellung der Scheibe 6 um den Betrag 10 in die strichpunktierte Lage möglich ist.The spray bell 1 with a knife-like chamber has a hollow shaft 3, which is 4 @ -seen with holes through which the paint component flowing out of the tube 5 reaches the inside of the bell 1. At a slight distance behind the plane of the Spray edge 2 is a spray disk 6 with a knife-like spray edge 7 arranged, the hollow, front open shaft 8 fixed to the hollow shaft 3 of the bell 1 is connected. Both hollow shafts 3 and 8 can be threaded so that an axial adjustment of the disc 6 by the amount 10 in the dot-dash position is possible.
Für die Zufuhr der zweiten Lackkomponenten zu der Vorderseite der Scheibe 6 ist ein Rohr 9 vorgesehen, das in die Hohlwelle 8 der Scheibe 6 hineinragt.For the supply of the second paint components to the front of the Disc 6, a tube 9 is provided which protrudes into the hollow shaft 8 of the disc 6.
