The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing the utility model is further described, the content that embodiment is mentioned not is to qualification of the present utility model.
Be the embodiment one of modified spray nozzle described in the utility model as shown in Figures 1 to 4, comprise hollow airduct 1 and be sheathed on hollow feed pipe 2 in the hollow airduct 1, the lower end of hollow airduct 1 offers the conical tuyere 3 that goes out, this is conical to go out in tuyere 3 external contractings to expand, the lower end of described hollow feed pipe 2 is provided with the middle part and is hollow paint nozzle 4, the inwall lower end of this paint nozzle 4 is provided with conical discharging opening 5, the lower end of paint nozzle 4 is provided with wind-guiding outlet 41, this wind-guiding outlet 41 and go out between the tuyere 3 gapped, the inside of described hollow airduct 1 is provided with even air duct 6, and the inwall of this even air duct 6 offers the even wind groove 61 of internal spline shape.When carrying out spray process, high pressure draught flows downward from the gap between hollow airduct 1 and the hollow feed pipe 2, and from going out tuyere 3 ejections; Coating flows downward from the inside of hollow feed pipe 2, and comes out from the discharging opening 5 of paint nozzle 4 lower ends; Converge from discharging opening 5 coating that comes out and the high pressure draught that goes out tuyere 3, from going out tuyere 3 ejections, during ejection, coating becomes vaporific coating to last coating under the effect of high pressure draught with high pressure draught, vaporific coating is attached to coated surface, thereby realizes its spray process.The inside of hollow airduct 1 described in the utility model is provided with even air duct 6, when high pressure draught flows to the upper end of even air duct 6, stopped by even air duct 6, the high pressure draught of dense inequality converges at the upper end of even air duct 6, the high pressure draught of dense inequality forms dense uniform high pressure draught through converging the back, and be assigned to equably in the even wind groove 61 of spline shape, lower end ejection from even wind groove 61, after the uniform distribution of high pressure draught through even air duct 6, from going out tuyere 3 ejections, improve the uniformity of spraying greatly again, thereby effectively improved the coating quality of spray process, effect is remarkable, and is practical.
The described hollow airduct 1 and the even air duct 6 of present embodiment are one-body molded, to reduce the production process of hollow airduct 1 and even air duct 6, reduce production costs by enhancing productivity, with hollow airduct 1 and even air duct 6 one-body molded after, production cost is lower, and described modified spray nozzle is practical more economically.
Described hollow feed pipe 2 inside of present embodiment are provided with thimble 7 moving up and down, and the lower end of this thimble 7 is provided with the taper putty head 71 that cooperates with described discharging opening 5.These taper putty head 71 usefulness opening and closing discharging openings 5, after moving on the thimble 7, taper putty head 71 separates with discharging opening 5, coating can successfully flow out from discharging opening 5, after thimble 7 moved down, discharging opening 5 was blocked by taper putty head 71, thereby stopped the spraying action, control is convenient, and practicality is stronger.
Be provided with positioning sleeve 8 in the described hollow feed pipe 2 of present embodiment, this positioning sleeve 8 offers and is used for the material hole 81 that confession coating passes, and the middle part of positioning sleeve 8 offers correction hole 82, and described thimble 7 passes this correction hole 82.Because the length that thimble 7 extend in the hollow feed pipe 2 is longer, in actual spray process process, after thimble 7 passes this correction hole 82, can avoid influencing the effect of the conveying or the spraying of coating effectively, guarantee normally carrying out of spray process because of the swing of thimble 7.
