Abstract

The blade is held by a holder (8) comprising a single profile (11) with a cross-section that forms a channel (10) for supplying wetting fluid to a nozzle (16). The blade is mounted in a groove (13) in the profile.

Description

25 30 35 40 525 302 2 uppfinningen åstadkoms detta genom att skrapbladshållaren utgörs av en strängpressad eller formgjuten profil med en innesluten kanal för framledning av vatten eller emulsion till vätningsmunstycken. Den inneslutna kanalen undanröjer tidigare tätningsproblem och bibehåller sin funktion vid yttre påverkan även om denna orsakar mindre kvarstående deformationer av profilen. Den inneslutna kanalen ger dessutom skrapbladshållaren en ökad böj styvhet. Den strängpressade profilen kan med fördel utföras i aluminium men även andra metallegeringar eller polymerer är tänkbara. 25 30 35 40 525 302 2 the invention is achieved in that the scraper blade holder consists of an extruded or molded profile with an enclosed channel for the supply of water or emulsion to wetting nozzles. The enclosed channel eliminates previous sealing problems and maintains its function in the event of external influences, even if this causes minor residual deformations of the profile. The enclosed channel also gives the scraper blade holder an increased bending stiffness. The extruded profile can advantageously be made of aluminum, but other metal alloys or polymers are also conceivable.

En arman fördel är att en skrapa, utförd enligt uppfinningen, har betydligt färre ingående detaljer än kända skrapor. Antalet ingående detaljer i skrapan kan givetvis ytterliggare reduceras om man integrerar skrapbladet i profilen. Det är då lämpligast att utforma profilen i ett polymerrnaterial, Uppfinningen kommer att närmare beskrivas med hjälp av bifogade figurer, där Figur l visar skrapors placering på en tvåvals självgående vibrationsvält. Figur 2 visar skrapan enligt utföringsexempel 1 fiamifrån med välten delvis visad. Figur 3 visar en vertikalsektion av skrapan enligt utföringsexempel 1 medan Figur 4 visar samma men enligt utföringsexempel 2.Another advantage is that a scraper, made according to the invention, has significantly fewer detailed details than known scrapers. The number of components in the scraper can of course be further reduced if the scraper blade is integrated in the profile. It is then most suitable to design the profile in a polymeric material. Figure 2 shows the scraper according to embodiment 1 fi from the outside with the roller partially shown. Figure 3 shows a vertical section of the scraper according to embodiment 1 while Figure 4 shows the same but according to embodiment 2.

I Figur l är de avsuykande och vätande skrapoma 2 anbringade mot valsama 3 på den självgående välten 1. Skrapoma trycksätts med vatten eller emulsion från vältens vattentankar 5 genom självtryck eller via pumpar 4.In Figure 1, the suction and wetting scrapers 2 are mounted against the rollers 3 on the self-propelled roller 1. The scrapers are pressurized with water or emulsion from the water tanks 5 of the roller by self-pressure or via pumps 4.

I Figur 2 visas den främre skrapan 2 enligt utföringsexempel l fiarnifrån anbringad mot valsen via skrapfästen 6 vilka kan utföras stelt eller fördelaktigare ledbart och fjäderbelastat infásta i vältens valsram 7. Det senare för att möjliggöra att skrapan enkelt kan fällas ut från valsen för rengörning av denna men också för att ge skrapbladet 12 ett lämpligt anliggningstryck mot valsen 3. Skrapan består av en skrapbladshållare 8 vars i gavlama myrmande inre kanal 10 tillslutes med pluggar 9.Figure 2 shows the front scraper 2 according to exemplary embodiment l from the outside mounted against the roller via scraper brackets 6 which can be made rigid or more advantageously articulated and spring-loaded fastened in the roller frame 7 of the roller. but also to give the scraper blade 12 a suitable abutment pressure against the roller 3. The scraper consists of a scraper blade holder 8 whose inner channel 10 muddy in the ends is closed with plugs 9.

Skrapbladshållaren bör ges en längd L som är något kortare än valsbredden B och kan med fördel utgöras av en strängpressad aluminiumprofil. På Skrapbladshållaren monteras skrapbladet 12 som bör ges en längd som något överstiger B. Skrapbladet bör utformas i ett polymerrnaterial, speciellt rekommenderas polyuretan.The scraper blade holder should be given a length L which is slightly shorter than the roll width B and can advantageously consist of an extruded aluminum profile. The scraper blade holder 12 is mounted on the scraper blade holder, which should be given a length that slightly exceeds B. The scraper blade should be designed in a polymeric material, polyurethane is especially recommended.

I Figur 3 visas en vertikalsektion av skrapan från figur 2 enligt utföringsexempel 1 där kanalen 10 är arrangerad sluten i den profil 11 som utgör Skrapbladshållaren. Skrapbladet 12 är monterad i ett i profilen 11 öppet arrangerat fástspår 13 och är låst i detta med ett antal skruvförband 14. Kanalen 10 trycksätts med vatten eller emulsion via en koppling 15 och de till kanalen anslutna vätningsmunstyckena 16 påverkas på detta sätt till lO 15 20 25 30 35 40 525 302 3 att väta valsen 3 genom besprutning. Vätningsmunstyckena har i detta utfóringsexempel integrerats i profilen och får i detta utförande en fast orientering relativt avstrykaren. Vätningsmunstyckena kan även bestå av separata munstycken med fast eller justerbar orientering som ansluts till kanalen.Figure 3 shows a vertical section of the scraper from figure 2 according to embodiment 1 where the channel 10 is arranged closed in the profile 11 which constitutes the scraper blade holder. The scraper blade 12 is mounted in a fastening groove 13 arranged in the profile 11 and is locked therein with a number of screw connections 14. The channel 10 is pressurized with water or emulsion via a coupling 15 and the wetting nozzles 16 connected to the channel are actuated in this way to 10 25 30 35 40 525 302 3 to wet the roll 3 by spraying. In this exemplary embodiment, the wetting nozzles have been integrated in the profile and in this embodiment have a fixed orientation relative to the wiper. The wetting nozzles can also consist of separate nozzles with fixed or adjustable orientation which are connected to the duct.

I Figur 4 visas samma som i Figur 3 men enligt utfóringsexempel 2.Figure 4 shows the same as in Figure 3 but according to embodiment 2.

Fästspâret 13 har här en annan geometri och skrapbladet 12 fastklämmes mot skrapbladshållaren 8 med ett anhåll 17 och ett antal skruvtörband 14.The fastening groove 13 here has a different geometry and the scraper blade 12 is clamped against the scraper blade holder 8 with a stop 17 and a number of screw dryer bands 14.
