Definitions

  • the invention relates to a nozzle head for dispensing a flat spray jet of a coating agent, in particular an insulating material for the insulation of motor vehicle body components.
  • Such a nozzle head is known per se from the prior art and consists essentially of two identical outer plates and a thin, smaller center plate, which is inserted between the two outer plates, wherein FIG. 8 an embodiment of such a conventional center plate 1 shows.
  • the center plate 1 has spraying off an end edge 2 with a substantially V-shaped contour, so that between the adjacent outer plates and the front edge 2 of the center plate 1, a nozzle chamber is formed, in which the insulating material is introduced.
  • a flat, fan-shaped spray jet forms, which is well suited for the application of the insulating material.
  • the middle plate 2 has on both sides slots 3, 4 for the passage of screws in order to screw the outer plates to the middle plate 1.
  • the beam width - if the volume flow is kept constant - in the beam plane from a certain minimum distance in front of the nozzle head distance independent almost constant.
  • the beam width then varies only in a range of ⁇ 2 mm.
  • This distance-independent constant beam width is particularly advantageous in the treatment of strongly curved component surfaces, since it is then not necessary to maintain a constant distance between the nozzle head and the component surface when driving off the component surface.
  • the beam width varies depending on the volume flow of the applied insulating material, which is also acceptable within the scope of the invention.
  • nozzle head having features according to the preamble of claim 1.
  • the known nozzle head is used to deliver a spray jet of a coating agent, wherein the spray jet is substantially flat in a jet plane and thereby has a certain beam width, and has two outer plates and an intermediate middle plate with outer tips on both sides and a central recess.
  • DE 27 56 133 A discloses an extruder head for applying a high viscosity liquid such as. B. magnetic ink on a relatively moving substrate such. B. magnetizable recording tapes with a guide plate whose edge forms an acute angle with a guide surface for the magnetic tape.
  • a disadvantage of the known nozzle head described above is the fact that the distance-independence of the beam width is given only within a relatively narrow volume flow working range. On the other hand, outside of this volumetric flow operating range, the beam width varies relatively strongly as a function of the distance to the nozzle head. An operation is therefore possible in practice only within the relatively narrow volume flow working range.
  • the invention is therefore based on the object to improve the above-described conventional nozzle head accordingly.
  • the nozzle head according to the invention should be suitable for different volume flows of the insulating material, wherein the beam width should remain constant as independent as possible of the distance to the nozzle head.

  • the beam width is only independent of the distance to the nozzle head from the minimum distance, whereas the beam width can also vary in the nozzle head according to the invention as a function of the volume flow.
  • the jet width of the spray jet can also vary in the case of the nozzle head according to the invention as a function of the volume flow of the application medium. If, however, the volume flow is kept substantially constant within the volume flow working range, then the jet width in the nozzle head according to the invention is essentially constant independent of the distance from the minimum distance.
  • the volume flow or outflow rate can be, for example, 10 cm 3 / s, 20 cm 3 / s, 30 cm 3 / s, 40 cm 3 / s, 50 cm 3 / s, 60 cm 3 / s, 70 cm 3 / s, 80 cm 3 / s, 90 cm 3 / s or 100 cm 3 / s, in each case preferably ⁇ 5 cm 3 / s, ⁇ 10 cm 3 / s or ⁇ 15 cm 3 / s.
  • the beam width is not exactly constant even in the case of the nozzle head according to the invention. Rather, the jet width can also vary with the nozzle head of the invention depending on the distance to the nozzle head fluctuations of ⁇ 1mm, ⁇ 2mm, ⁇ 4mm, ⁇ 6mm, ⁇ 8mm, ⁇ 10mm, ⁇ 12mm, ⁇ 14mm or even ⁇ 16mm.

  • the nozzle head is in particular designed so that the volume flow working range with the substantially distance-independent constant beam width a Volumetric flow range of at least ⁇ 5 cm 3 / s, ⁇ 10 cm 3 / s, ⁇ 15 cm 3 / s, ⁇ 20 cm 3 / s, ⁇ 25 cm 3 / s, ⁇ 40 cm 3 / s, ⁇ 80 cm 3 / s or ⁇ 90 cm 3 / s.
