Description
Gegenwärtig existieren eine Reihe von verschiedenen Spritzpistolen (Handapplikationen), mit welchen 2-Komponentenkleber auf die zu verklebende Oberfläche aufgetragen wird. Diese Handapplikationen bestehen darin, die beiden Komponenten des Klebers zusammenzuführen, durchzumischen und in der erforderlichen Geometrie mit dem erforderlichem Druck austreten zu lassen, sodass sie auf die Klebefläche aufgetragen werden können. Die 2-Komponentenkleber bestehen üblicherweise aus einer Härterkomponente und einer entsprechenden Klebstoffkomponente.At present, there are a number of different spray guns (hand applications), with which 2-component adhesive is applied to the surface to be bonded. These hand applications consist in bringing together the two components of the adhesive, mixing them and leaving them in the required geometry with the required pressure so that they can be applied to the adhesive surface. The 2-component adhesives usually consist of a hardener component and a corresponding adhesive component.
Für die Verarbeitung werden verschiedene Typen von Handapplikationen verwendet Das heißt, die Verarbeitung, Zuführung und Durchmischung der 2 Komponenten miteinander ist unterschiedlich. Zentrale Zuführung der B Komponente, dezentrale Zuführung der B Komponente mit anschließender Durchmischung in einem statischen Mischer. Zuführung der beiden Komponenten in ein dynamisches Mischwerk.Various types of hand applications are used for processing. That is, the processing, feeding and mixing of the two components is different. Central feeding of the B component, decentralized feeding of the B component with subsequent mixing in a static mixer. Feeding the two components into a dynamic mixer.
Die zum Auspressen nötige Druckkraft kann dabei elektrisch oder pneumatisch erzeugt werden.The pressure required for pressing pressure can be generated electrically or pneumatically.
Dabei treten oft folgende Probleme auf
- – Beim Auspressen der Klebstoffkomponente aus dem Beutel kommt es zum Verkannten des mit der Schubstange fest verbundenen Presskolben, sodass keine gleichmäßige Bewegung mehr stattfindet, gegebenenfalls wird der Beutel zwischen Presskolben und Zylinder eingeklemmt und damit beschädigt.
- – Ein weiteres Hindernis besteht darin, dass meist Restteile und Klebstoff in der Handapplikation verbleiben, sodass eine sehr zeitaufwendige Reinigung erfolgen muss.
- - When squeezing the adhesive component from the bag it comes to Verkve of firmly connected to the push rod connected pressing piston, so that no more uniform movement takes place, possibly the bag between the plunger and cylinder is clamped and thus damaged.
- - Another obstacle is that mostly residual parts and adhesive remain in the hand application, so that a very time-consuming cleaning must be done.
Diese Hindernisse sollen durch das vorliegende Gebrauchsmuster gelöst werden. Üblicherweise besteht die Handapplikation im Wesentlichen aus der Austrittsdüse, dem statischem Mischer, in welcher die beiden Komponenten durchgemischt werden, der Vormischkammer, in welcher die beiden Komponenten zusammentreffen, dem Presszylinder, in welchem sich der Klebstoffbeutel befindet, einer aufgesetzten Plastikscheibe und einer dahinter befindlichen Metallplatte, die den Druck erzeugt (siehe Zeichnung 1 und 2). Um ein Verkanten zu vermeiden, wird auf die Metallplatte ein Kunststoffpresskolben aufgesetzt, der mit der Platte nicht fest verbunden ist Der Kunststoffpresskolben verfügt beidseitig über angearbeitete Dichtlippen. Auf diesen Kunststoffpresskolben kann, ebenfalls flexibel, auf der Auspressseite in Kolbenrichtung eine entsprechende Auspressform aufgesetzt werden, sodass sich die Effektivität der gesamten Anordnung erhöht, d. h. dass weniger Restmaterial im Zylinder nach Beendigung des Prozesses verbleibt Druckseitig wird der Kunststoffpresskolben von einer Metallplatte angetrieben, die auf der Schubstange fest angebracht ist. Damit wird der gesamte Druck auf die Scheibe, Kunststoffpresskolben, Presskolbenaufsatz und somit auf den Klebstoffmaterialbeutel übertragen. Von besonderer Bedeutung ist dabei, dass der Druck, welcher sowohl pneumatisch als auch elektrisch erzeugt werden kann, während des gesamten Prozesses homogen und ohne Rucken und Verklemmen erfolgt Deshalb ist die Verbindung zwischen dem Kunststoffpresskolben und der Metallscheibe nicht fest, sondern flexibel. Das wird dadurch erreicht, dass der Kunststoffpresskolben auf die Metallscheibe nur aufgesteckt ist. Außerdem besitzt die Metallscheibe eine Unterlegscheibe, sodass beim Andrücken der Metallscheibe auf die Kunststoffscheibe eine leichte Wölbung stattfindet. Dadurch entsteht der Effekt, dass die sich die Kunststoffscheibe im Zylinder anpasst und somit eine ruckfreie, homogene Bewegung zulässt. Des Weiteren ist ein Teil der Vormischkammer auswechselbar, d. h. ein Teil besteht aus einem einfachen Plastikkörper, welcher nach Beendigung des Prozesses ausgewechselt und verworfen werden kann. Dadurch entfällt der aufwendige Reinigungsprozess.These obstacles are to be solved by the present utility model. Usually, the manual application consists essentially of the outlet nozzle, the static mixer, in which the two components are mixed, the premixing chamber, in which the two components meet, the pressing cylinder, in which the adhesive bag is located, an attached plastic disc and a metal plate located behind it that creates the pressure (see drawing 1 and 2). In order to avoid tilting, a plastic plunger is placed on the metal plate, which is not firmly connected to the plate The plastic plunger has on both sides on-worked sealing lips. On this plastic pressing piston can, also flexible, on the extrusion side in the piston direction a corresponding Auspressform be placed, so that the effectiveness of the entire arrangement increases, d. H. that less residual material remains in the cylinder after completion of the process on the pressure side, the plastic pressing piston is driven by a metal plate which is fixedly mounted on the push rod. Thus, the entire pressure on the disc, plastic plunger, pressing piston attachment and thus transferred to the adhesive material bag. Of particular importance is that the pressure, which can be generated both pneumatically and electrically, during the entire process is homogeneous and without jerking and jamming Therefore, the connection between the plastic piston and the metal disc is not fixed, but flexible. This is achieved by the fact that the plastic press piston is only attached to the metal disk. In addition, the metal disc has a washer, so that when pressing the metal disc on the plastic disc takes place a slight curvature. This creates the effect that the plastic disc in the cylinder adapts, allowing a jerk-free, homogeneous movement. Furthermore, a part of the premixing chamber is interchangeable, d. H. a part consists of a simple plastic body, which can be replaced and discarded after completion of the process. This eliminates the costly cleaning process.
