Definitions
- the invention relates to a nozzle change holder for high-pressure paint spray guns according to the preamble of claim 1.
- nozzle change holders are generally known and available on the market.
- the object of the present invention is therefore to provide an improved nozzle change holder for high-pressure paint spray guns, which enables quick and easy replacement of the nozzles and is simple and inexpensive to manufacture, but nevertheless ensures the required tightness.
- the solution to this problem results from the characterizing features of the protection claim 1.
- the replacement of the nozzle can thus be accomplished by simply pulling out and pushing in the nozzle holder which has a handle, which can be carried out quickly and without tools.
- excellent tightness is guaranteed over a long period of use because the seals used are only statically loaded and can be axially clamped.
- slight screw movements can be used to re-tighten seals that are in use for longer periods of time, and moreover, a simple adjustment of the slot direction of slot nozzles is possible by moving the handle of the nozzle holder.
- the interchangeable holder consists of a union nut 10 with a sealing ring 11, a retaining screw 12 with a brake spring 13 and a sealing cup 14, a nozzle cage 15 with an axial slot 15a and a retaining spring 16, a nozzle holder 17 and a nozzle guard 18.
- the nozzle holder 17 has an axial bore for inserting a nozzle 19, a sealing washer 20 and a press ring 21 and a laterally projecting handle 22.
- the retaining screw 12 is inserted into the union nut 10 and the sealing ring 11 is inserted, whereupon the union nut is screwed onto the usual external thread of the mouth of the paint spray gun barrel (not shown), namely until the edge of the gun barrel mouth and the rear edge of the retaining screw 12 compress the sealing ring 11.
- the retaining spring 16, which has the shape of a slotted ring with bent slot ends, and the nozzle guard 18 are plugged onto the nozzle holder 15 in such a way that the axial slot of its sleeve part 18a with the axial slot 15a of the nozzle cage 15 flees.
- the nozzle change holder is now ready for use with the nozzle holder 17.
- the nozzle 19, which may be a standard nozzle, and the sealing disk would be inserted into the axial bore of the nozzle holder 17 and secured in the axial bore by pressing the press ring 21.
- the nozzle holder 17 can now be pushed into the nozzle cage 15 by widening the slot end of the retaining spring 16 through the slot 15a, the central axis of the nozzle 19 then coinciding with the central axis of the nozzle cage 15 and the handle 22 outward from the slot 15a of the nozzle cage 15 protrudes; the retaining spring 16 which contracts again due to its own elasticity after the insertion process ensures that the nozzle holder remains in the nozzle cage and can only be pulled out of the nozzle cage 15 again using tensile force.
- the nozzles for high-pressure paint spray guns are generally slot nozzles and it can now be the case with the assembly described above that the slot direction of the nozzle 19 deviates considerably from the desired spray jet level.
- the union nut 10 is loosened again slightly, the component protruding from the union nut is rotated in the desired direction (pre-adjustment of the nozzle slot direction) and the union nut is tightened again.
- a fine adjustment of the nozzle slot direction can now be carried out in such a way that the handle 22 of the nozzle holder 17 is moved a little bit upwards or downwards, with the result of a rotation of the nozzle cage 15 on the thread of the retaining screw 12.
- the rotation can be in in each direction by an amount of, for example, up to twenty degrees, without the cup seal 14 being compressed too much or being relieved in such a way that a seal would no longer be guaranteed. It is essential here that with this movement of the handle 22, the nozzle guard 18 also rotates in a corresponding manner, so that there is no need to readjust the nozzle guard 18, but rather it is always in the desired manner relative to the nozzle slot.
- the spraying process can now be carried out, and, as tests have shown, also with color presses up to 400bar and above that the required sealing is guaranteed.
- nozzle 19 If the nozzle 19 is now to be exchanged for another nozzle, for example with a larger or smaller throughput, then it is only necessary to pull the nozzle holder 17 by its handle 22 out of the nozzle cage 15 against the force of the retaining spring 16, the nozzle 19 by a replace other nozzle and push the nozzle holder 17 back into the nozzle cage 15 in the manner described above. It is even easier if there are several nozzle holders 17 available which are equipped with different nozzles 19; in this case, only the socket 17 located in the cage 15 is then pulled out and replaced by a socket 17 with another nozzle 19; in this case only seconds are required to change the nozzle.
- the invention is not limited to the exemplary embodiment shown, rather numerous modifications are possible without departing from the scope of the invention. It is essential, however, that the seals are only subjected to static loads and can be axially clamped, because this ensures the least possible wear and aging of the seals and it is also possible to compensate for any aging of the seal by, for example, opening the nozzle cage a little further unscrewed the retaining screw.
