Definitions

  • the invention relates to a device for generating a adjustable liquid jet, especially when applying Glue and / or soft liquid on a web, with a nozzle head, one with one at the end one with the one to be processed Arranged liquid flow path Opening provided nozzle, being in the area of the opening elastic element is provided, the one with the Has flow path communicating passage recess and that between two by means of one on the nozzle holder provided adjusting device adjustable relative to each other Press organs inform one of the front, the elastic element receiving nozzle tube and an engaging, pierced pressure bolt is arranged.
  • a at least one with the passage recess of the elastic Elements communicating, through hole provided Piston arrangement is provided, which in the nozzle tube, the Nozzle head is rigidly attached, engaging pressure bolts, one adjoining this, on the side facing away from the pressure pin Side a pressure chamber to which a pressure medium can be applied limiting actuating piston and one of them on the Push pin protruding from the opposite side, one has a smaller diameter sealing pin, the sealing in one going from the pressure room, with the processing fluid pressurized bore intervenes.
  • the drawing shows a nozzle head according to the invention partially on average.
  • the nozzle head 5 shown consists of a housing block 40, to which a nozzle 41 is flanged. This has one on her front end conically narrowed, a front opening 34 having nozzle tube 19 which is connected to a rear flange 42nd is formed, which is fastened to the housing block 40 by screws is.
  • a Housing block 40 provided cylinder space 43. This owns a larger diameter than the bore of the nozzle tube 19 and is closed outside of this by the flange 42.
  • elastic element 18 is provided, which is a central Passage recess 17 which is in the region of the front Opening 34 of the nozzle tube 19 opens out and with a feed line 16 for in the form of a beam onto a substrate, for example a moving paper web, liquid that can be applied, for example glue or soft liquid.
  • a substrate for example a moving paper web
  • liquid that can be applied for example glue or soft liquid.
  • the nozzle tube 19 which is rigidly arranged is inserted and supported by this elastic element 18 by an in the nozzle tube 19 engaging pressure pin 20 more or less strongly pressed against the associated support surface of the nozzle tube 19.
  • the pressure pin 20 is in the housing block 40 arranged actuating device actuated.
  • an adjusting piston 44 is arranged in the cylinder space 43 provided, of which the one with a smaller diameter Push pin 20 protrudes downwards and on the Push pin 20 opposite side a pressure chamber 45 limited by a supply connection 46 with a Pressure medium, for example compressed air, can be acted upon.
  • the pressure of the pressure medium can be used to regulate the crushing of the elastic element 18 to be adjustable.
  • the maximal Actuating movement of the actuating piston 44 is by a stop limited.
  • the flange 42 can be threaded be provided in which an adjusting screw 47 is received, the forms an adjustable stop.
  • the flange 42 can also with be provided with a ventilation recess 48.
  • a blind bore 49 goes upwards, into which the feed line 16 opens for the liquid to be processed.
  • an attached to the actuating piston 44 engages the sealing pin 50 opposite the pressure pin 20. This is opposite the wall of the blind bore 49 by means of O-rings sealed.
  • the actuating piston 44 is also opposed by O-rings sealed the wall of the associated cylinder space 43.
  • the actuating piston 44 and the pressure bolt 20 and Sealing pin 50 form a piston arrangement in the form of a Stepped piston.
  • This entire piston assembly is one central through hole 51 to which the Through recess 17 of the elastic element 18 connects, whereby the through recess 17 of the elastic Element 18 is connected to the feed line 16.
  • the depth of engagement of the sealing pin 50 in the blind bore 49 is larger than that maximum travel of the actuating piston 44, so that the sealing pin 50th in any case remains in engagement with the blind bore 49, whereby the pressure chamber 45 reliably with respect to the feed line 16 for the liquid to be processed remains sealed. This will regardless of the position of the actuating piston 44 via the central Through recess 51 of the central through recess 17 of the elastic element 18 supplied.
