Description
Spannvorrichtung für Siebgewebe bei Querspannern Die Erfindung bezieht sich auf eine Spannvorrichtung, durch welche das Siebgewebe elastisch gespannt wird, bei der die Spannkraft unmittelbar in die Siebrahmenquerträger übertragen wird und deren Durchtrittsöffnung durch die Rahmenseitenwand vollkommen und einfach abgedichtet werden kann.Tensioning device for screen mesh in cross tensioners The invention relates on a tensioning device through which the screen mesh is elastically tensioned, in which the clamping force is transmitted directly to the screen frame cross member and whose passage opening is completely and simply sealed by the frame side wall can be.
Es sind Spannvorrichtungen bekannt, bei denen die nachlassende Elastizität des Siebgewebes im Gebrauch durch zusätzliche elastische Mittel, wie Schrauben- oder Tellerfedern, ausgeglichen wird. Nach Nachteil dieser Mittel besteht darin, daß sie beim Gewebewechsel leicht verlorengehen. Ein weiterer Nachteil der bekannten Spannvorrichtungen ist darin zu sehen, daß die Spannkraft ein großes Biegemoment auf die Seitenwand ausübt, so daß diese zusäztlich ausgesteift werden muß. Außerdem kann bei den bekannten Spannvorrichtungen der Durchtritt durch die Seitenwand nur unvollkommen oder mit großem Aufwand abgedichtet werden.There are clamping devices known in which the decreasing elasticity of the screen mesh in use by additional elastic means, such as screw or disc springs. The disadvantage of these means is that that they are easily lost when the tissue is changed. Another disadvantage of the known Clamping devices can be seen in the fact that the clamping force has a large bending moment exerts on the side wall, so that this must be additionally stiffened. aside from that can only pass through the side wall with the known clamping devices imperfectly or with great effort.
Die Spannvorrichtung gemäß der Erfindung besteht in bekannter Weise aus einer Spannschiene, an welcher ein Spannbolzen gelenkig angreift, dessen Spannmutter sich außerhalb der Siebrahmenwand über eine kugelige Scheibe an einem Widerlager abstützt. Die Erfindung ist jedoch dadurch gekennzeichnet, daß dieses Widerlager selbst elastisch ist, vorzugsweise eine gebogene Blattfeder, die durch Schrauben oder Niete unmittelbar mit einem Querträger des Siebrahmens verbunden ist.The clamping device according to the invention consists in a known manner from a tensioning rail, on which a tensioning bolt engages in an articulated manner, its tensioning nut outside the screen frame wall via a spherical disc on an abutment supports. However, the invention is characterized in that this abutment itself is elastic, preferably a curved leaf spring, which is screwed or rivet is connected directly to a cross member of the screen frame.
In den Zeichnungen sind Ausführungsformen der Erfindung schematisch dargestellt. Im einzelnen zeigt A b b. 1 einen Schnitt durch die Spannvorrichtung in Normalausführung, A b b. 2 die Ansicht einer Einzelheit in Pfeilrichtung A, A b b. 3 einen Schnitt durch die Spannvorrichtung in Sonderausführung, A b b. 4. die Ansicht einer Einzelheit in Pfeilrichtung B.In the drawings, embodiments of the invention are schematic shown. In detail, A b b. 1 shows a section through the clamping device in standard design, A b b. 2 shows a view of a detail in the direction of arrows A, A. b b. 3 a section through the clamping device in special design, A b b. 4. the View of a detail in the direction of arrow B.
An der Spannschiene 1 greift der Spannbolzen 2 gelenkig an. Die Spannmutter 3 stützt sich außerhalb der Siebrahmenwand 4 über die kugelige Scheibe 5 gegen die gebogene Blattfeder 6 ab. Die Spannkraft wird durch Schrauben oder Niete 7 in den Querträger 8 übertragen. Bei Naßabsiebung kann die Durchtrittsöffnung 9 durch ein elastisches Formstück 10, beispielsweise aus Gummi oder Kunststoff, abgedichtet werden. Zur Zeitersparnis beim Gewebewechsel kann die Spannmutter 3 auf einer Seite des Siebrahmens durch einen Riegel 11 ersetzt werden, der durch einen entsprechenden Schlitz im Spannbolzen 2 geschoben wird.The tensioning bolt 2 engages the tensioning rail 1 in an articulated manner. The clamping nut 3 is supported outside the screen frame wall 4 via the spherical disk 5 against the curved leaf spring 6. The clamping force is transmitted to the cross member 8 by screws or rivets 7. In the case of wet screening, the passage opening 9 can be sealed by an elastic molded piece 10, for example made of rubber or plastic. To save time when changing the tissue, the clamping nut 3 can be replaced on one side of the sieve frame by a bolt 11 which is pushed through a corresponding slot in the clamping bolt 2.
