Abstract
Description
Die Erfindung betriff eine Düse, insbesondere für den Auftrag hochviskoser Stoffe, mit einem Stoffauslass und einem um diesen herum angeordneten Gasauslass.The invention relates to a nozzle, in particular for the application of highly viscous substances, with a pulp outlet and a gas outlet arranged around it.
Eine derartige Düse ist beispielsweise aus der
Hierbei kann die Luftzufuhr so geregelt werden, dass dickere Klebstoffstränge, feine Klebstofffäden oder gesprühte Klebstofftröpfchen entstehen.Here, the air supply can be controlled so that thicker adhesive strands, fine adhesive threads or sprayed adhesive droplets arise.
Durch Bohrungen oder Ausfräsungen in der Luftdüse kann die Luft optimal zugeführt werden, um auch Klebstoffe mit hohen Viskositäten auftragen zu können.Through holes or cutouts in the air nozzle, the air can be optimally supplied in order to apply even adhesives with high viscosities.
Diese Düsen haben sich gut bewehrt, sie sind jedoch aufwendig in der Herstellung.These nozzles have been well armed, but they are expensive to manufacture.
Der Erfindung liegt daher die Aufgabe zu Grunde, eine derartige Düse weiterzuentwickeln, indem die Herstellungsweise vereinfacht wird.The invention is therefore based on the object to further develop such a nozzle by the manufacturing method is simplified.
Diese Aufgabe wird mit einer gattungsgemäßen Düse gelöst, bei der der Gasauslass ein Deflektorblech aufweist.This object is achieved with a generic nozzle in which the gas outlet has a deflector plate.
Das Deflektorblech ist ein einfaches Bauteil, das im Gasauslass angeordnet werden kann, um dem Gas eine spezielle Strömungsrichtung zu geben. Je nach technischer Anforderung kann ein anderes Deflektorblech in den Luftkanal der Düse eingesetzt werden um eine spezielle Luftströmung zu erzielen. Bei einer Beschädigung des Deflektorbleches, einer Verschmutzung durch von der Luft eingebrachten Partikeln oder bei Korrosion am Deflektorblech kann das Deflektorblech einfach ausgetauscht werden.The deflector plate is a simple component that can be placed in the gas outlet to give the gas a specific flow direction. Depending on the technical requirements, another deflector plate can be inserted into the air duct of the nozzle to achieve a special air flow. In the event of damage to the deflector plate, contamination caused by airborne particles or corrosion on the deflector plate, the deflector plate can be easily replaced.
Während bisher spezielle Düsen durch Bohrungen oder erodierte Kanäle bereitgestellt werden mussten, reicht im vorliegenden Fall ein einfaches Deflektorblech, das in den Luftkanal der Düse eingelegt wird. Die Düse ist daher einfach herstellbar, individuell anpassbar und leicht zu reparieren.While previously special nozzles had to be provided by drilling or eroded channels, in the present case, a simple deflector plate is sufficient, which is inserted into the air duct of the nozzle. The nozzle is therefore easy to manufacture, customizable and easy to repair.
Besonders vorteilhaft ist es, wenn das Deflektorblech eine Fächerscheibe ist. Fächerscheiben sind als Schraubensicherungen bekannt und besonders günstig in der Herstellung. Dabei können verschiedene Arten an Fächerscheiben verwendet werden, sofern sie in ihrem radialen Bereich einen Gasdurchfluss quer zur Erstreckung der Fächerscheibe erlauben und dabei dem Gas einen Drall verleihen.It is particularly advantageous if the deflector plate is a fan disc. Fan discs are known as threadlockers and are particularly inexpensive to manufacture. In this case, different types of fan discs can be used, provided they allow in their radial region a gas flow across the extension of the fan disc and thereby impart a twist to the gas.
Es wird daher vorgeschlagen, dass das Deflektorblech aus der Ebene des Bleches herausragende, verdrehte Flügel aufweist. Das Deflektorblech kann damit im Wesentlichen die gleiche Materialstärke aufweisen. Durch die aus der Ebene des Bleches herausragenden, leicht verdrehten Flügel entsteht eine Luftführung, die dem Luftstrom einen Drall verleiht. Derartige Bleche können einfach gestanzt werden und sie sind daher besonders günstig herstellbar.It is therefore proposed that the deflector plate has protruding, twisted wings out of the plane of the sheet. The deflector plate can thus have substantially the same material thickness. The lightly twisted wings, which protrude from the plane of the sheet, create an air duct that gives the air flow a twist. Such sheets can be easily stamped and they are therefore particularly inexpensive to produce.
Um von außen einen zentralen Stoffauslass zu umgeben und dadurch den Stoff mit einem Gas zu führen, wird vorgeschlagen, dass der Stoffauslass konzentrisch im Gasauslass angeordnet ist. Somit umgibt die zugeführte Luft ringförmig den Stoffauslass, um den austretenden Stoff zu führen.In order to surround from the outside a central Stoffauslass and thereby to lead the substance with a gas, it is proposed that the substance outlet is arranged concentrically in the gas outlet. Thus, the supplied air surrounds annularly the pullout outlet to guide the exiting material.
Vorteilhaft ist es, wenn das Deflektorblech ringförmig um den Stoffauslass angeordnet ist. Dies ermöglicht es, mit einem einzigen Deflektorblech die um den Stoffauslass herum zuströmende Gasströmung zu führen.It is advantageous if the deflector plate is arranged in a ring around the substance outlet. This makes it possible to use a single deflector plate to guide the gas flow flowing around the material outlet.
Das Deflektorblech kann einfach auf den Stoffauslass aufgesetzt sein. Eine für die Luftführung benötigte Hülse kann dann das Deflektorblech halten und gegen den Stoffauslass drücken.The deflector plate can simply be placed on the Stoffauslass. A sleeve needed for the air guide can then hold the deflector plate and press against the fabric outlet.
Insbesondere bei der Verwendung von Klebstoffen oder zähflüssigen Materialien ist es vorteilhaft, wenn der Stoffauslass eine Öffnung mit einem Nadelventil aufweist. Das die Öffnung verschließende Nadelventil sorgt dafür, dass sich kein Klebstoff im Stoffauslass verfestigt oder eintrocknet.In particular, when using adhesives or viscous materials, it is advantageous if the Stoffauslass has an opening with a needle valve. The needle valve closing the opening ensures that no glue solidifies or dries in the fabric outlet.
Bei der Verwendung eines derartigen Nadelventils ist es vorteilhaft, wenn das Deflektorblech in der Ebene des Nadelventils angeordnet ist. Dadurch wird der Gasströmung direkt am Auslass des Stoffes ein Drall aufgeprägt, der direkt anschließend den austretenden Stoff erfasst und führt.When using such a needle valve, it is advantageous if the deflector plate is arranged in the plane of the needle valve. As a result, the gas flow is imparted a swirl directly at the outlet of the substance, which then directly detects and guides the exiting substance.
Um die Düse optimal einstellen zu können wird vorgeschlagen, dass Stoffauslass und Gasauslass mit einer regulierbaren Zuführung in Verbindung stehen. Die Zuführung kann den Druck am Stoff und am Gas variieren, um je nach Einsatzgebiet eine Leimraupe oder einen Sprühnebel zu erzeugen.In order to be able to optimally adjust the nozzle, it is proposed that the substance outlet and gas outlet be connected to a regulatable feed. The feeder may vary the pressure on the fabric and on the gas to produce a glue bead or spray, depending on the application.
