Diese Erfindung betrifft eine Vorrichtung zum Schmelzen und Verteilen thermoplastischen Werkstoffes und besteht aus einem Gehäuse mit einer darinnen gelegenen Ausgabeöffnung, einer Wärmeschmelzkammer und einem mit diesen koaxial ausgerichteten Einlaßkanal für einen thermoplastischen Werkstoffkörper. Die Erfindung bezieht sich insbe- ' sondere auf ein Handwerkzeug zum Schmelzen und Verteilen thermoplastischen Klebstoffes.This invention relates to an apparatus for melting and dispensing thermoplastic material and consists of a housing with a dispensing opening therein, a heat melting chamber and an inlet channel coaxially aligned therewith for a thermoplastic Material body. The invention relates in particular to a hand tool for melting and Spreading thermoplastic adhesive.
Wärmeschmelzzemente bieten, da sie lösemittelfrei sind und schnell abbinden, eine Reihe von Vorteilen. Ein aus vielerlei Gründen beliebtes »System«, das sich wegen seiner einfachen Klebstoffzuführung und wegen der kurzen Zeit, während derer der Klebstoff auf erhöhten Temperaturen gehalten zu werden 1S braucht, mit dem thermoplastischer Klebstoff direkt geschmolzen und verteilt werden kann, ,ist in verschiedenen Ausführungsarten zur Anwendung gekommen. In einem derartigen System wird eine Stange oder ein Strang festen thermoplastischen Klebezements nach Bedarf in die Einlaßöffnung eines erwärmbaren Schmelzkanals, in dem der Zement schmilzt, eingeschoben und alsdann in geschmolzenem Zustand auf die zu verklebende Fläche aufgetragen. Im allgemeinen stammt die zum Fördern des Klebstoffes durch die Vorrichtung nötige Kraft von einem Pumpmittel, das als sich drehendes Rad, als Zahnradpumpe oder als einfache Kolben-Zylinder-Einheit ausgebildet sein kann. Derlei Pumpvorrichtungen werden angewandt, weil es in der Praxis schwierig ist, die Einlaßöffnung des Schmelz- und Verteilergerätes dem Klebstoffkörper derart eng anzupassen, um auf die Stange oder den Strang des Klebstoffes einen zum Treiben des Klebstoffes durch die Vorrichtung hinreichend starken Druck auszuüben. Außerdem erwärmt sich die Einlaßöffnung mitunter so weit, daß der Klebstoffkörper erweicht oder sogar schmilzt, so daß er an den Wänden der Einlaßöffnung festklebt und beim Weitertreiben der Stange einige Schwierigkeiten verursacht, besonders beim erneuten Inbetriebnehmen der Vorrichtung nach ihrem Erkalten. Um solchen Schwierigkeiten vorzubeugen, sind schon Vorrichtungen verwendet worden, die entweder mit Kühlvorrichtungen versehen waren oder deren Einlaßkanäle aus einem Wärme nicht leitenden Stoff mit niedriger Reibung bestanden. Es hat sich jedoch erwiesen, daß selbst selche Maßnahmen unter Umständen ein Erwärmen des Einlaßkanals nötig machen, ehe die Stange oder der Strang des Werkstoffes frei durch die Vorrichtung getrieben werden kann.As they are solvent-free and set quickly, hot-melt cements offer a number of advantages. A favorite for many reasons "system", which because of its simple adhesive supply and because of the short time during which to be held, the adhesive at elevated temperatures for 1 S needs directly melted with the thermoplastic adhesive and can be distributed, is in various Types of execution come into use. In such a system, a rod or a strand of solid thermoplastic adhesive cement is pushed as required into the inlet opening of a heatable melt channel in which the cement melts and then applied in the molten state to the surface to be bonded. In general, the force required to convey the adhesive through the device comes from a pumping means, which can be designed as a rotating wheel, as a gear pump or as a simple piston-cylinder unit. Such pumping devices are used because it is difficult in practice to adapt the inlet opening of the melting and distribution device to the adhesive body so closely as to exert sufficient pressure on the rod or strand of adhesive to force the adhesive through the device. In addition, the inlet opening sometimes heats up to such an extent that the adhesive body softens or even melts, so that it sticks to the walls of the inlet opening and causes some difficulties in driving the rod further, especially when the device is restarted after it has cooled down. In order to prevent such difficulties, devices have already been used which were either provided with cooling devices or whose inlet channels consisted of a heat-non-conductive material with low friction. It has been found, however, that even such measures may require the inlet duct to be heated before the rod or strand of material can be driven freely through the device.

Schmelz- und Verteilervorrichtung zu schaffen, die einem teilweise geschmolzenen und sich anschließend an den Wänden der Einlaßöffnung erhärteten Klebstoffkörper bei dessen Durchtreiben durch die Vorrichtung merklich verringerten Widerstand entgegensetzt, wobei das Vorwärtsbewegen eines festen thermoplastischen Klebezementkörpers einen wirksamen Druck hervorruft, um geschmolzenen Klebstoff aus der Vorrichtung auf ein Werkstück aufzutragen.Melting and distributing device to create a partially melted and subsequently hardened adhesive body on the walls of the inlet opening as it is driven through the device opposed noticeably reduced resistance, the advancement of a solid thermoplastic Glue cement body creates effective pressure to pull molten glue out to apply the device to a workpiece.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß der Einlaßkanal aus durch eine radial ausbiegbare Manschette aus einem wärmebeständigen, Wärme nicht leitenden gummiartigen elastischen Material gebildet ist, deren innere Flächen sich den äußeren Flächen des Klebstoffkörpers anpassen.According to the invention, the object is achieved in that the inlet channel by a radially bendable Cuff made of a heat-resistant, heat-non-conductive rubber-like elastic Material is formed, the inner surfaces of which adapt to the outer surfaces of the adhesive body.
Vorzugsweise liegt die Manschette, weiche zweckmäßigerweise aus einem Silikon- oder Fluorelastomer besteht, axial in einer Höhlung des Gehäuses, welche eine größere lichte Weite als der Außendurchmesser der Manschette aufweist.The cuff is preferably made from a silicone or fluoroelastomer consists, axially in a cavity of the housing, which has a greater internal width than the outer diameter of the cuff.
