Description

Blockkochpresse zur Herstellung von zwei Blöcken aus Celluloid oder ähnlicher 1Vlasse Blockkochpressen für Celluloitd und ähnliche Massen dienen dazu, -den vosb:ere@tetem Rohstoff in einem Preßraum (Blockkorffer) unter Druck zu erhitzen und darauf wieder ,ukühlen und dadurch ein Block zu er-# -tb7 en zeugen, der dann weiterverarbeitet wird. Es sind Blockkochpressen bekannt, bei welchen in jedem Arbeitsgang nur ein Block erzeugt wird; jedoch- gibt :es auch Blockkoühpressen;, bei welchen zwei Blöcke in einem Preßraum (Blockkoffer) gleichzeitig hergestellt werden.Block cooking press for the production of two blocks of celluloid or similar 1Vlasse block cooking presses for celluloid and similar masses are used to - heat the prepared raw material in a press room (block body) under pressure and then cool it again, thereby creating a block # -tb7 en which is then further processed. Block presses are known in which only one block is produced in each operation; However, there are: there are also block presses, in which two blocks are produced in one press room (block case) at the same time.

Bei solchen Zweiblockpressen wird der Preßraum für die beidem. Blöcke durch eine Zwischenplatte in zwei Teile geschieden. Bei den- bekannten Pressen lieb diese Zwischenplatte lose zwischen den beiden Blöcken, so daß sie bei ungleichmäßiger Einfüllung und bei der durch die Erhitzung verfolgenden Erweichung des Rohstoffes sich schief stellen konnte, was den Nachteil hat, daß die Blöcke nicht genau prismatisch ausfaHen und bei der Weiterverarb:eitungerheblichen Abfall jergebexn.In such two-block presses, the press room is for both. blocks divided into two parts by an intermediate plate. Loved by the well-known presses this intermediate plate loosely between the two blocks, so that they are uneven when Filling and the softening of the raw material as a result of the heating could be askew, which has the disadvantage that the blocks are not exactly prismatic dump and in further processing: inconsiderable waste is discarded.

Dieser Nachteil wird durch die Bleckkochpresse nach der Erfindung dadurch 'vermieden, daß die Zwischenplatte in dem Blockkoffer durch Riegel :oder andere Befestigungsmittel, die während des Ausstoßeis der fertigen Blöcke ausgelöst werden können, feststellbar ist.This disadvantage is caused by the sheet cooking press according to the invention thereby 'avoided that the intermediate plate in the block case by bolt: or other fasteners triggered during the ejection of the finished blocks can be determined.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt. Die Presse besteht aus dem Preßzyli;ndera, dem Preßkolbenb und ,der Preßplatte c sowie dem Oberholm d, welcher durch die Säulen e mit dem Preßzylinder a verbunden isst. Der Blockkoffer f ist an den Säulen verschiebbar und kann :durch die Hebekolbeng gehoben und die an dem Oberholm befestigten Druckkolbenh gesenkt werden. In Abb. i ist in den Blockleoffer f der Rohstoff 1 für den ersten Block eingefüllt. Auf den Rohstoff i wird die Zwischenplatte h aufgelegt und durch lUegell befestigt, welche von außen her durch die Wandung des Blockkoffers/ eingeschoben werden. Die Riegel l können durch Hebel. und Zugstangen in beliebiger Weise so verbunden werden, daß sie durch einen einzigen Handgriff vorgeschoben werden. Auf die Zwischenplatte k wird der Rohstoffan für den zweiten Block Jufgeschichbet. Nunmehr wird der Blockkoffer f durch die Flebekolbeng angehoben und gleichzeitig der Hauptpreßkolbenh unter Druck gesetzt, so daß der Rohstoff i und m für die beiden Blöcke zwischen der Preßplatte c und dem von oben her in den Blockkoffer eindringen; den Oberholm d gepreßt wird. Gleichzeitig wird durch Heizeinrichtungen der Rohstoff erhitzt und durch Kühleinrichtungen nachher abgekühlt. Nacherfolgtem Arb.eibsvorgang wird der Blockkoffer f durch die Druckkolbenh heruntergedrückt. Nachdem die Riegell zurückgezogen und die Verbindung zwischen Zwischenplatte k und Blockkoffer f gelöst ist, können die beiden fertigen Blöcke nebst der Zwischenplatte h durch den Preßkolben h nach Oben ausgestoßen werden. Während des Preßvorganges ist also die Zwischenplatte h mit dem Blockk offer f fest verbunden und kann sich nicht schief stellen.An exemplary embodiment is shown in the drawing. The press consists of the press cylinder, the press piston b and, the press plate c and the upper beam d, which is connected to the press cylinder a by the columns e. The block case f can be moved on the pillars and can: be lifted by the lifting piston and the pressure pistons attached to the upper beam lowered. In Fig. I, the raw material 1 for the first block is filled into the block loader f. The intermediate plate h is placed on the raw material i and fastened by lUegell, which are inserted from the outside through the wall of the block case /. The latch l can by lever. and tie rods are connected in any manner so that they are advanced by a single handle. The raw material for the second block is placed on the intermediate plate k. Now the block case f is raised by the Flebekolbeng and at the same time the Hauptpreßkolbenh is put under pressure, so that the raw material i and m for the two blocks between the press plate c and the penetrate into the block case from above; the upper beam d is pressed. At the same time, the raw material is heated by heating devices and then cooled down by cooling devices. After the work process has taken place, the block case f is pressed down by the pressure pistons. After the bolt has been withdrawn and the connection between the intermediate plate k and the block case f has been released, the two finished blocks along with the intermediate plate h can be ejected upwards through the plunger h. During the pressing process, the intermediate plate h is firmly connected to the Blockk offer f and cannot be askew.
