Description

Das: Patent 864 7 ji. bezieht sich auf die Ausrüstung von -Kunststöffplattenträgern für Siebmaschinen äller Art mit Feinlochsiebblechen. Danach werden Feinlochsiebbleche auf bei normaler Temperatur harte thermoplastische Kunststoffplatten; die als Tragrahmen dienen, mit Hilfe von schlitzgeschweißten Raupen oder durch Hochfreduenzschweißung unter Druck befestigt. Auf diese Weise bleibt ein großer (Querschnitt für den Siebdurchgang frei, und die empfindlichen Siebbeläge werden beispielsweise auf rasch schwingenden, modernen Sieben weder durch Flatter-Bewegungen noch durch zu hohe Spannkräfte bei der Befestigung zerstört. In weiterer Ausbildung des Erfindungsgegenstandes wurde nun gefunden, daß man auch gröbere ,Siebbeläge, beispielsweise mit Maschenweiten zwischen o,2 und 1,5 mm, vorteilhaft auf thermoplastische Kunststoffplattenträger mit weiten Durchgangsöffnungen aufschweißen kann. Da aber bei diesen weitmaschigen Geweben das thermoplastische weichgemachte Material des Trägers leicht durch die Maschen durchtritt, gelingt es auf gegenüber dem Hauptpatent vereinfachte Weise die Siebe aufzuziehen.The: Patent 864 7 ji. refers to the equipment of plastic plate carriers for all kinds of screening machines with fine perforated screen plates. Then fine perforated sieve plates are made on thermoplastic plastic sheets that are hard at normal temperature; as a support frame serve, with the help of slot-welded beads or high-efficiency welding fastened under pressure. This leaves a large (cross-section for the sieve passage free, and the sensitive screen linings are, for example, on rapidly vibrating, modern sieving neither by fluttering movements nor by too high tension forces the fortification destroyed. In further training the subject of the invention was now found that you can also use coarser, screen coverings, for example with mesh sizes between 0.2 and 1.5 mm, advantageously on a thermoplastic plate carrier can weld on with wide openings. But since with these wide-meshed ones The thermoplastic plasticized material of the wearer easily weaves through the weave Meshes, it succeeds in a simplified manner compared to the main patent to open the sieves.

Erfindungsgemäß braucht man nur die Siebbeläge auf den weit perforierten Plattenträger oder die Stützplatte vorgespännt aufzulegen und dann längs der stehengebliebenenRippen usw. mit Hilfe eines heißen Plätteisens in den thermoplastischen Stoff hineinzudrücken. Verwendet man für den Kunststoffplattenträger beispielsweise den unter der 'Bezeichnung Hartigelit bekannten -Werkstoff oder Polyvinylchlorid, so wird man dem Plätteisen eine Flächentemperatur von ioo bis iio° C erteilen. Für Polystyrol ist eine etwas höhere Temperatur-zu wählen, während man für Silikone Temperaturen bis 2oo° C zum Einsatz bringen muß. Durch "das heiße Aufplätten unter geringen, leicht von Hand auszuübenden Drücken erzielt man eine Art Einschmelzen und Einsinken der Maschendrähte in den Kunststofftragrahmen.According to the invention, you only need the screen linings on the widely perforated ones Place the plate carrier or the support plate in a pretensioned position and then along the remaining ribs etc. to be pressed into the thermoplastic material with the help of a hot flat iron. If one uses for the plastic plate carrier, for example, the one under the name Hartigelit well-known material or polyvinyl chloride, this is how you get the flat iron give a surface temperature of 100 to 100 ° C. There's something for polystyrene higher temperature to choose, while for silicone temperatures up to 2oo ° C to Must bring commitment. By "the hot flattening under low, lightly by hand The pressures to be exerted produce a kind of melting and sinking of the wire mesh in the plastic support frame.

An Stelle von glatten Kunststoffstützplatten kann man auch nach der Abbildung Kunststoffstützplatten benutzen, an denen die Ränder der Durchbrechungen oder Löcher nach unten vom Sieb weg durchgedrückt sind. Auf diese Weise erhält man noch größere Versteifung der Stützplatte. Nach der Abbildung sind in der durchlaufend gedachten Platte i erfindungsgemäß die Durchbrechungen 2 vorgesehen, deren Wulst 3 die Durchbrechungen versteifend umgibt.Instead of smooth plastic support plates, you can also use the Use plastic support plates to fix the edges of the perforations or holes are pushed down away from the sieve. That way you get even greater stiffening of the support plate. According to the illustration are in the continuous imaginary plate i according to the invention provided the openings 2, the bead 3 surrounds the perforations stiffening.
