Description
Einrichtung an Vulkanisiermas chinen Die Erfindung betrifft eine Einrichtung an Vulkanisiermaschinen, die im wesentlichen aus einer rotierenden Trommel, über die das zu vulkanisierende Gut geleitet wird, und einem mit der Trommel umlaufenden Anpreßband bestehen, welches das Vulkanisat gegen die Trommel drückt, wobei sowohl die Trommel als auch das Anpreßband beheizt sind und die Beheizung des Anpreßbandes mittels Strahlungswärme erfolgt.Device on Vulkanisiermas chinen The invention relates to a device on vulcanizing machines, which essentially consist of a rotating drum which is directed to the material to be vulcanized, and one rotating with the drum There are pressure belt, which presses the vulcanizate against the drum, with both the drum and the pressure belt are heated and the pressure belt is heated takes place by means of radiant heat.
Derartige Vulkanisfermaschinen eignen sich vor allem zur kontinuierlichen Vulkanisation von Platten und bandförmigen Gegenständen. Die Umlaufges chwind igkeit der Trommel und die Beheizung bestimmen hierbei die höchstmögliche Stärke des Vwlkanisates.Such Vulkanisfermaschinen are particularly suitable for continuous Vulcanization of plates and tape-shaped objects. The speed of circulation the drum and the heating determine the maximum strength of the volcanic material.
Zur Steigerung der Beheizung wurde deshalb bereits vorgeschlagen, nicht nur die Trommel von innen her, sondern auch das Anpreßband von außen her, also dessen Rückenfläche, mittels D ampfschl augen oder elektrisch zu beheizen. Des weiteren ist es bekannt, das zu vulkanisierende einlaufende Gut durch die von der Trommel abgestrahlte Wärme vorzuwärmen, wobei das Gut dicht an den freien Mantelteil der Heiztrommel herangeführt wird. Eine Rückenbeheizung des Anpreßbandes ist hierbei jedoch nicht vorgesehen. To increase the heating, it has therefore already been proposed that not only the drum from the inside, but also the pressure belt from the outside, So its back surface can be heated by means of steam blowers or electrically. It is also known that the incoming goods to be vulcanized by the to preheat the heat radiated from the drum, with the material close to the free shell part the heating drum is brought up. A back heating of the pressure belt is here but not provided.
Zur Lenkung des Gutes um die Trommel muß dieses eine bestimmte Formbeständigkeit besitzen. Dünnwandige und ausschließlich aus Kautschuk bestehende Bahnen müssen daher von einer Stoffbahn, z. B. einem zugfesten Band, geleitet werden.To direct the goods around the drum, it must have a certain dimensional stability own. Thin-walled membranes made exclusively of rubber must be used therefore from a web of fabric, e.g. B. a tensile tape are conducted.
Auch ist es bekannt, thermoplastische Massen mittels Infrarotstrahlern zu erwärmen. It is also known to produce thermoplastic compositions by means of infrared emitters to warm up.
Im Gegensatz hierzu ist gemäß der Erfindung vorgesehen: 1. die Beheizung des Anpreßhandes mittels Infrarotstrahlern durchzuführen, 2. die Strahler so anzuordnen, daß die Einlaufstelle für das zu vulkanisierende Gut stärker beheizt wird als die Aulslaufstelle. und 3. an der Einlaufstelle zwischen dem zu vulkanisierenden Gut und der Trommel Strahlungsquellen anzubringen. In contrast, the invention provides: 1. The heating of the contact hand by means of infrared radiators, 2. to arrange the radiators in such a way that that the inlet point for the material to be vulcanized is heated more than that Starting point. and 3. at the point of entry between the item to be vulcanized and to attach radiation sources to the drum.
Dlie Beheizung mittels Infrarotstrahlern ermöglicht das Ein- und Ausschalten der Anlage innerhalb von wenigen Minuten, da beim Einschalten unverzüglich eine intensive Erwärmung einsetzt und nach dem Abschalten der Strahlungsquellen keine Wärme mehr erzeugt wird. Durch die Beheizung mit Infrarotstrahlern läßt sich die Wärmezufuhr sehr gut regeln. und es sind hohe Temperaturen an dem Anpreßband erzielbar. Dlie heating by means of infrared heaters enables the on and off The system is switched off within a few minutes, since it is switched on immediately intensive heating begins and after the radiation sources have been switched off no more heat is generated. By heating with infrared radiators, regulate the heat supply very well. and there are high temperatures on the pressure belt achievable.
Hierbei können neben lampenförmigen Strahlern stabförmige Strahler Verwendung finden. Letztgenannte Strahlungsquellen haben den Vorteil, daß man sie in gebogener Form zur Anwendung bringen kann, wo sie der Trommelform angepaßt werden können. Eine zu starke oder ungleichmäßige, auf bestimmte Abschnitte konzentrierte Beheizung des Anpreßbandes ist nicht zu befürchten, da die gewöhnlich stählernen Anpreßbänder ein so großes Wärmeleitvermögen besitzen, daß ein schneller Temperaturausgleich stattfindet und eine örtliche Überhitzung nicht stattfinden kann. Da darüber hinaus die Einlaufstelle für das zu vulkanisierende Gut stärker beheizt wird als die Auslaufstelle, wird eine für die Vulkanisation günstige Wärmeverteilung erreicht. Die weiterhin vorgesehenen, zwischen dem zu vulkanisierenden Gut und der Trommel angeordneten Strahler wärmen das einlaufende Gut vor, so daß sich dieses wilhg verformen läßt, wenn es zwischen Anpreßband und Trommel gelangt. In addition to lamp-shaped emitters, rod-shaped emitters can be used here Find use. The latter radiation sources have the advantage that they can be used apply in a curved shape where they can be adapted to the shape of the drum can. Too strong or uneven, focused on certain sections There is no need to fear that the pressure belt will be heated, as they are usually made of steel Pressure bands have such a high thermal conductivity that a rapid temperature equalization takes place and local overheating cannot take place. Since in addition the inlet point for the product to be vulcanized is heated more strongly than the outlet point, a favorable heat distribution for vulcanization is achieved. Which continues provided, arranged between the material to be vulcanized and the drum Emitters preheat the incoming goods so that they can be deformed, if it gets between the pressure belt and the drum.
Es ist ferner von besonderer Bedeutung und sehr vorteilhaft, daß durch die auf die Rückenfläche des Anpreßbandes einwirkenden und die zwischen der Trommel und dem zu erwärmenden Gut befindlichen Strahler eine beidseitige innige Erwärmung des zu vulkanisierenden Gutes erfolgt. It is also of particular importance and very advantageous that by acting on the back surface of the pressure band and between the Drum and the radiator located to be heated is a two-sided intimate The material to be vulcanized is heated.
Die Erfindung wird an Hand einer schematischen Zeichnung beispielsweise dargestellt. Die Zeichnung zeigt eine Seitenansicht einer Vulkanisierneaschine. The invention is illustrated by means of a schematic drawing, for example shown. The drawing shows a side view of a vulcanizing machine.
Die Vulkanisiermaschine besteht im wesentlichen aus einer beheizten Trommel 1, die in Richtung des Pfeiles 2 rotiert. Das als Stahlband ausgebildete Anpreßband 3 ist um die Trommel 1 herumgeführt, und es bewegt sich ebenfalls in Richtung des Pfeiles 2. Das bereits bandförmig angelieferte, zu vulkanisierende Gut 4 wird auf das Stahlband 3 gelegt, so daß dieses zwischen Anpreßband 3 und der Trommel 1 gelangt. The vulcanizing machine essentially consists of a heated one Drum 1 rotating in the direction of arrow 2. The one designed as a steel band Pressure belt 3 is guided around the drum 1, and it also moves in Direction of arrow 2. The one to be vulcanized, which has already been delivered in the form of a tape Good 4 is placed on the steel belt 3, so that this between the pressure belt 3 and the Drum 1 arrives.
Das fertige Vulkanisat 4' verläßt die Trommel 1 an der Stelle 5. Die Beheizung der Rückenfläche des Anpreßbandes 3 erfolgt mit Hilfe von Infrarotstrahlern 6.The finished vulcanizate 4 'leaves the drum 1 the Point 5. The back surface of the pressure belt 3 is heated with the aid of Infrared emitters 6.
Diese sind an der Einlaufstelle konzentriert, während ihre Dichte zur Auslaufstelle 5 hin abnimmt. Zur Vorwärmung des Materials 4 sind noch Strahlungsquellen 6' zwischen dem einlaufenden Gut und der Trommel 1 vorgesehen.These are concentrated at the point of entry, while their density towards the outlet point 5 decreases. Radiation sources are still used to preheat the material 4 6 'is provided between the incoming goods and the drum 1.
