Problems solved by technology

In order to transform the pre-shaped beam from the cylindrical tube of the central air nozzle opening into other shapes, for example from a round beam to a flat beam, the high energy from the beam shaping hole and the angular hole is necessary, which results in large energy losses and limits beam shaping
[0008] The big disadvantage of this method of beam shaping is that a large part of the energy used for beam shaping and re-atomization is already on the surface due to narrow boreholes and multiple discharges to the ambient air (in connection with the large velocity difference). large shear plane) and loses its effect

Embodiment Construction

[0031] exist figure 1 and 2 The spray head for a paint spray gun shown in , has a paint nozzle body 1 with a substantially cylindrical paint channel 2 which opens centrally into a paint nozzle 3 . A hollow paint needle 4 is inserted into the paint nozzle 3 . The paint nozzle 3 is surrounded by an air ring nozzle 5 into which air can be supplied via a channel 6 . The air cap 7 is screwed onto the gun body by means of a ring 203, commonly referred to as an air nozzle ring. However, the gas cap 7 may also be fixed on the gun body by other means. In this embodiment, the air cap 7 is made by plastic injection molding. The gas cap has an annular section 8 which rests snugly against the gun body. A substantially planar cover plate 9 is connected to the annular section 8 . In the region of the so-called spout, the cover plate 9 has an annular bead 10 protruding from the planar region 9 , in the center of which an opening 11 emerges. When the paint nozzle 3 is mounted, the openi...

Abstract

The invention relates to a nozzle head for a spray device, comprising a central material nozzle, an air ring nozzle surrounding said material nozzle, and preferably at least two laterally projecting horns, into each of which at least one horn air nozzle is incorporated, and optionally comprising a material-conducting needle, characterized in that at least one nozzle (3, 3a, 3b, 5, 5a, 12, 12a, 12b, 15, 16, 17, 17a, 17b, 17c, 18, 18a, 18b1, 18b2, 18b3, 300a, 300b), preferably at least one horn air nozzle (15, 16, 17, 17a, 17b, 18, 18b1, 18b2, 18b3, 300a), has a non-cylindrical shape.

Description

[0001] This application is based on the invention that entered the Chinese national phase on November 28, 2012, the national phase application number is 201180026602.9, and the invention name is "spray head for spraying device" (international application number is "PCT / EP2011 / 002544") Divisional application. technical field [0002] The invention relates to a spray head for a spray device according to the preamble of claim 1 . Background technique [0003] Such nozzles are used in spraying devices for hydrostatic atomization, pneumatic atomization or combined hydrostatic and pneumatic atomization of paints, lacquers, adhesives or other liquid materials, especially on paint spray guns. common. [0004] In the spray head of such a spray device, the function of the air ring nozzle is to discharge the compressed air supplied to the device as an air jet with high energy, which sucks up, atomizes the material from the other central nozzle and A spray jet entraining the material ...
