Abstract
The utility model discloses a nozzle for powder spraying, which comprises a connecting pipe and a diffusion pipe, wherein one end of the connecting pipe is communicated with a spray gun for providing powder fluid, and the other end of the connecting pipe is communicated with the diffusion pipe; the diffusion tube stretches into the connecting pipe and the junction between the two is equipped with the dispersion seam, the diffusion tube stretches into the end frame and is equipped with the spiral fan. The utility model discloses discrete powder that both can be even at the spraying in-process can improve the blowout powder directive property again to improve the utilization ratio of powder. The effect of uniform spraying is realized through spraying at two positions of the dispersing seam and the outlet of the diffusion tube; diffusion tube one end stretches into in the connecting tube, has and carries out directive discrete effect to the powder fluid, has improved the blowout powder directive property, and the utilization ratio of powder improves.
Description
Technical field
The utility model relates to nozzle technology field, especially a kind of powder spraying nozzle.
Background technology
Powder spraying is a kind of widely used spraying technology, its working process is: powder sprays in electrostatic field by nozzle is evenly discrete, by the effect of electrostatic field, powder being adsorbed on workpiece surface, the powder then adsorbed is through high bake, solidification, and finally forms coating.
Traditional nozzle is primary structure only, and by the compulsory object that the separation of powder fluid reaches even discrete powder, although can reach uniform effect like this, but the directive property of ejection powder greatly reduces, and the utilization ratio of powder is low.
Practical novel content
The utility model is for the deficiencies in the prior art, it is proposed to a kind of powder spraying nozzle, sprays evenly, and directive property is good.
In order to realize the novel object of above-mentioned practicality, the utility model provides following technical scheme: a kind of powder spraying nozzle, comprises pipe connecting and diffuser tube, and the spray gun of powder fluid is connected with providing in described pipe connecting one end, and the other end is connected with described diffuser tube; Described diffuser tube stretch into described pipe connecting and between the two junction be provided with dispersion seam, described diffuser tube inserting end erection have screw fan.
Preferably, described diffuser tube stretches into the length of described pipe connecting is 30mm.
Preferably, the cross section of described pipe connecting is circular or square.
Compared with prior art, the utility model has the following advantages: in spraying process both can uniform discrete powder, again can improve ejection powder directive property, to improve the utilization ratio of powder. The spraying of two places is exported, it is achieved the evenly effect of spraying by dispersion seam and diffuser tube; Diffuser tube one end is stretched in pipe connecting, have the discrete effect that powder fluid carries out directive property, it is to increase ejection powder directive property, and the utilization ratio of powder improves.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of powder spraying nozzle of the utility model.
Embodiment
Being described in detail by the utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, it should not protection domain of the present utility model is had any restriction.
A kind of powder spraying nozzle as shown in Figure 1, comprise pipe connecting 1 and diffuser tube 2, the cross section of pipe connecting 1 is circular or square, the spray gun of powder fluid is connected with providing in its one end, the other end is connected with diffuser tube 2, both junctions are provided with dispersion seam 3, and powder will spray to workpiece from dispersion seam 3 and diffuser tube 2 exit end, it is to increase uniformity coefficient.
Diffuser tube 2 part stretches in pipe connecting 1, and the length of inserting end is 30mm, and sets up screw fan 4 at inserting end, the powder come in by pipe connecting 1, part drives screw fan 4 to rotate and obtain flowing to change, and through dispersion seam 3 ejection, another part enters diffuser tube 2 through the entrance 21 of diffuser tube 2.
During work, a part for powder fluid is by dispersion seam 3 by evenly discrete and form Uniform jet and spray to workpiece, and another part arrives diffuser tube 2 by entrance 21 and exports, and has the jet of directive property, sprays to workpiece, and the utilization ratio of powder is improved.
The above is only preferred implementation of the present utility model; it is noted that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also making some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (3)
1. a powder spraying nozzle, it is characterised in that: comprising pipe connecting and diffuser tube, the spray gun of powder fluid is connected with providing in described pipe connecting one end, and the other end is connected with described diffuser tube; Described diffuser tube stretch into described pipe connecting and between the two junction be provided with dispersion seam, described diffuser tube inserting end erection have screw fan.
2. powder spraying nozzle as claimed in claim 1, it is characterised in that: it is 30mm that described diffuser tube stretches into the length of described pipe connecting.
