Abstract
The utility model discloses a self-mixing flat gun nozzle for spraying, which comprises a guide tube and a flat gun nozzle, wherein the guide tube is of a cylindrical structure, and an inlet is tangentially injected into the cylinder; the flat gun nozzle is coaxially communicated with the guide pipe, a discharge needle is erected in the guide pipe, and the needle point of the discharge needle is arranged at the outlet of the flat gun nozzle. The utility model discloses establish the guiding tube into whirlwind formula and pour into the powder into for the powder is at intraductal evenly distributed, and spun powder is more even, reaches good spraying effect.
Description
Technical field
The utility model relates to spraying equipment technical field, and especially a kind of spraying is with from the flat rifle mouth of mixing.
Background technology
Powder spraying is a kind of widely used spraying technology, working process is: powder sprays in electrostatic field by Spray gun 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; The key part ensureing coating quality in spraying process is Spray gun nozzle.
A long hole is opened on all front section equal Spray gun nozzle top of the flat rifle mouth used on current domestic market, the powder of ejection is made to form fan-shaped dust cloud, owing to the factors such as the adhesion between the gravity of powder self, powder make the powder of ejection easily be deposited on the lower end of Spray gun nozzle, cause ejection powder uneven.
Practical novel content
The utility model is for the deficiencies in the prior art, it is proposed to a kind of spraying with from the flat rifle mouth of mixing, make the powder of ejection evenly, reach desirable spraying effect.
In order to realize the novel object of above-mentioned practicality, the utility model provides following technical scheme: a kind of spraying is used from the flat rifle mouth of mixing, comprises guiding tube and flat rifle mouth, and described guiding tube is cylinder-like structure, and entrance is in tangential injection cylinder; Described flat rifle mouth and described guiding tube are coaxial communication, and described guiding tube internal frame is provided with electric discharge pin, and the needle point of described electric discharge pin is located at the exit of described flat rifle mouth.
Preferably, described guiding tube is made up of the two cylindrical sections connections that diameter is different, and the cylindrical section diameter that entrance is connected is relatively big, two cylindrical section coaxial communication.
Preferably, described guiding tube length is 120mm.
Compared with prior art, the utility model has the following advantages: guiding tube is set to cyclone type and injects powder so that powder is uniformly distributed in pipe, and the powder of ejection is more even, reaches good spraying effect.
Accompanying drawing explanation
Fig. 1 is that a kind of use that sprays of the utility model is from the sectional view mixing flat rifle mouth.
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 spraying as shown in Figure 1 is with from the flat rifle mouth of mixing, comprising guiding tube 1, flat rifle mouth 2, guiding tube 1 is made up of two cylindrical section structure coaxial communication, and entrance 3 is for being tangentially connected cylinder, the drum diameter that entrance 3 is connected is greater than another cylindrical section, and the cylinder that diameter is little is connected with flat rifle mouth 2; Powder is through the atomization ejection of flat rifle mouth 2. Guiding tube 1 is long is 120mm.
Powder leads in guiding tube 1 through tangential inlet 3, and along guiding tube 1 circumferential wall helicoidal flow, then through small diameter cylinder section, flow of powder is not change flow direction, it is to increase powder uniformity coefficient, is finally sprayed by flat rifle mouth 2, obtain spraying effect well.
In guiding tube 1, also erection has electric discharge pin 4, the needle point of electric discharge pin 4 is located at the exit of flat rifle mouth 2, and powder is entered in default electrostatic field, and the powder being convenient to ejection is easy to be adsorbed on spray-coating surface, it is to increase coating quality.
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 spraying is with from the flat rifle mouth of mixing, it is characterised in that: comprising guiding tube and flat rifle mouth, described guiding tube is cylinder-like structure, and entrance is tangentially inject in cylinder; Described flat rifle mouth and described guiding tube are coaxial communication, and described guiding tube internal frame is provided with electric discharge pin, and the needle point of described electric discharge pin is located at the exit of described flat rifle mouth.
2. spray with from the flat rifle mouth of mixing as claimed in claim 1, it is characterised in that: described guiding tube is made up of the two cylindrical sections connections that diameter is different, and the cylindrical section diameter of entrance connection is relatively big, two cylindrical section coaxial communication.
