Abstract
The utility model discloses a rotary diffusion head for an electrostatic spray gun, which comprises a short tubular body, wherein an adapter is arranged at the rear end of the short tubular body and engaged with the gun barrel opening of the electrostatic spray gun, an annular groove is formed inside the short tubular body, a fan blade is assembled inside the annular groove and can rotate freely around the annular groove, the fan blade comprises a rotary ring which is in clearance fit with the annular groove, more than two vanes are uniformly distributed on the inner circumference of the rotary ring, and the vanes are fixedly connected with one another. The diffusion head can further reduce the particle size of coating powders jetted out of the electrostatic spray gun, so as to improve the diffusion effect and reduce deposition of the coating powders.
Description
Technical field
The present invention relates to the electrostatic gun in the coated metal field, especially relate to a kind of diffusion tip that is installed on electrostatic gun gun barrel mouth.
Background technology
For hardware, under more situation, need carry out application to its surface, so that metal component surface has good antiseptic property, and make it more neat and artistic.For this reason; Usually adopt simple manual work to spray paint or the mode of electrostatic spraying; When adopting simple and easy manual work to spray paint,, therefore make surface of the work that the uneven situation of paint trickling takes place easily because the ejection of common spray gun is liquid paint; Finally cause coating fruit after the uneven thickness everywhere, coating quality is relatively poor.
In view of the foregoing; In the coated metal technology of present high requirement; Require to adopt the electrostatic spraying mode to carry out application, promptly adopt electrostatic gun that pulverous charged coating particles is sprayed to charged workpiece, make coating particles be adsorbed in surface of the work equably; Through high temperature melting, levelling, curing process, make coating be coated on surface of the work equably again; Its principle is: electrostatic gun connects a utmost point of power supply; Workpiece connects another utmost point of power supply; The powder type coating prepn particle is blown out by compressor in electrostatic gun, through the electrostatic generator (constituting) of muzzle by static pin or electrostatic disk charged after, make it evenly to be adsorbed by workpiece.
In this kind electrostatic gun, in order to improve the diffusion of the Powdered charged coating particles in rifle head place, to improve the spraying uniformity of coating particles; Generally need to increase a diffuser plate, yet the diffuser plate that adds usually is a staticizer; Its diffusion effect is still very limited, is easy to generate laying dust on the other hand, therefore; Rifle head disperser for electrostatic gun needs further improvement
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of electrostatic gun rotation diffusion tip, this diffusion tip can further improve diffusion effect to the further refinement of coating powder of electrostatic gun ejection, and is difficult for causing the alluvial of coating dust.
The technical solution adopted for the present invention to solve the technical problems is: this electrostatic gun rotation diffusion tip comprises the short tube body, and said short tube body rear end is provided with the running-on that is complementary with electrostatic gun gun barrel mouth; Offer cannelure one in the said short tube body, the flabellum that one of assembling can rotate freely around cannelure in this cannelure; Said flabellum comprises a change with said cannelure matched in clearance, circumferentially is uniformly distributed with two in the said change with blade, and each blade is fixed each other.
As preferably, the cross section of said change with the contacted fillet of all leading everywhere of said cannelure, to reduce the friction between change and the cannelure.
As preferably, said change inboard is provided with an annulus concentric with this change, is used for connecting fixing each said blade, thereby reduces the resistance of said flabellum center to coating powder.
Further improvement as above-mentioned optimal way; Said annulus, blade are made up of metallic object; And be electrically connected with electrostatic generator; The section edges of said annulus, blade is wedge angle, thereby makes annulus, blade edge place produce the electrostatic charge concentration effect, makes it in the process that coating powder is spread, further improve the carried charge of powder particle.
Beneficial effect of the present invention is: this electrostatic gun rotation diffusion tip in use; Only need to be set in the gun barrel mouth of electrostatic gun, when spray gun sprays coating powder through compressed air stream, will promote said flabellum rotation through said running-on; In rotary course; Flabellum makes coating powder obtain the centrifugal motion of dispersing, and outwards radial in the shape of a spiral ejection has improved diffusion effect greatly.
Description of drawings
Fig. 1 is the longitudinal section of first embodiment of a kind of electrostatic gun rotation of the present invention diffusion;
Fig. 2 is the front view of flabellum among Fig. 1 embodiment;
Fig. 3 be among Fig. 2 A-A to cutaway view.
Among the figure: 1, short tube body; 10, running-on; 21, blade; 22, change; 23, annulus.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
In the embodiment of Fig. 1-shown in Figure 3, this electrostatic gun rotation diffusion tip comprises short tube body 1, and said short tube body 1 rear end is provided with the running-on 10 that is complementary with electrostatic gun gun barrel mouth; Offer cannelure one in the said short tube body 1, the flabellum that one of assembling can rotate freely around cannelure in this cannelure; Said flabellum comprises a change 22 with said cannelure matched in clearance; Circumferentially be uniformly distributed with three blades 21 in the said change 22; Each blade 21 is consolidated on the concentric annulus 23 of said change 22 inboard and this change 22; Through this kind structure, can reduce the resistance of said flabellum center to coating powder.
Above-mentioned electrostatic gun rotation diffusion tip, the cross section of said change 22 with the contacted fillet of all leading everywhere of said cannelure, to reduce the friction between change 22 and the cannelure.
Above-mentioned electrostatic gun rotation diffusion tip, said annulus 23, blade 21 are made up of metallic object, and are electrically connected with electrostatic generator; The section edges of said annulus 23, blade 21 is wedge angle; As shown in Figure 3, the both sides of the edge of blade 21 cross sections are wedge angle, so; Can make annulus 23, blade 21 edges produce the electrostatic charge concentration effect, make it in the process that coating powder is spread, further improve the carried charge of powder particle; Inner in order to make electrostatic charge remain on this diffusion tip as much as possible, said short tube body 1 is made up of non-conductor, and its inwall can be made up of smooth pottery.
Above-mentioned electrostatic gun rotation diffusion tip in use; Only need to be set in the gun barrel mouth of electrostatic gun, when spray gun sprays coating powder through compressed air stream, will promote said flabellum rotation through said running-on 10; In rotary course; Flabellum makes coating powder obtain the centrifugal motion of dispersing, and outwards radial in the shape of a spiral ejection has improved diffusion effect greatly.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
