Abstract
The utility model relates to a head of a static spray gun. The head of the static spray gun comprises a cylinder, wherein a rotatable joint matched with a barrel of the static spray gun is arranged at the rear end of the cylinder; a spiral channel is formed inside the cylinder; the inlet end of the spiral channel penetrates through the rear end of the cylinder along the axial line of the cylinder in an extension mode, and the outlet end of the spiral channel is deviated from the axial line of the cylinder and penetrates through the front end of the cylinder in an extension mode; and the inner wall of the spiral channel is a rough surface. Compared with a diffusion plate, the static spray gun has the advantages that the diffusion degree of powdery coating particles can be improved to a great extent, and dust is difficult to accumulate.
Description
Technical field
The utility model relates to a kind of coated metal instrument, especially relates to electrostatic gun, especially, relates to the rifle head accessory of electrostatic gun.
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 purpose of the utility model is to provide a kind of electrostatic gun head, and this electrostatic gun can improve the diffusion of powder type coating prepn particle largely, and be difficult for laying dust with respect to diffuser plate.
The utility model solves the technical scheme that its technical problem adopted: this electrostatic gun head comprises one section cylinder; This cylinder rear end is equipped with the rotatable joint that is complementary with the electrostatic gun gun barrel; Said cylinder inside offers helical duct; The upstream end of this helical duct extends through the cylinder rear end along said cylinder axis, and the port of export of this helical duct departs from said cylinder axis and extends through the cylinder front end; Said helical duct inwall is a matsurface.
As preferably, said helical duct inwall is the annular burr that relies closely, and the spiral path line quadrature of each annular burr and said helical duct is to increase the circumferential thrust of coating powder air-flow to the helical duct inwall.
As preferably, the port of export of said helical duct is a horn mouth, so that good diffusion space is provided for coating powder.
As preferably, be provided with sealing ring in the said rotatable joint, be a hermetic seal swivel joint.
The beneficial effect of the utility model is: this electrostatic gun head can be assemblied in the gun barrel mouth of common electrostatic gun, and Compressed Gas sprayed coating powder from gun barrel after, the powder air communication sprayed after crossing said helical duct; Because the helical duct inwall is a matsurface, therefore, during powder airflow passes helical duct; To circumferentially promote helical duct, thereby force this electrostatic gun head rotation, in this process; The port of export of helical duct will make the powder of ejection under centrifugal action, improve diffusivity around said cylinder axis rotation, thereby obtain the better spraying uniformity; In addition, this diffusion structure is a bascule, therefore is difficult for laying dust.
Description of drawings
Fig. 1 is the structural representation of the utility model electrostatic gun head;
Fig. 2 is the vertical profile sketch map of Fig. 1 embodiment;
Fig. 3 is the spraying effect sketch map of the utility model electrostatic gun head.
Among the figure: 1, cylinder; 10, helical duct; 11, upstream end; 12, the port of export; 2, rotatable joint; 3, electrostatic gun gun barrel.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
In Fig. 1, embodiment shown in Figure 2; This electrostatic gun head comprises one section cylinder 1; This cylinder 1 rear end is equipped with the rotatable joint 2 that is complementary with electrostatic gun gun barrel 3; Said cylinder 1 inside offers helical duct 10, and the upstream end 11 of this helical duct 10 extends through cylinder 1 rear end along said cylinder 1 axis, and the port of export 12 of this helical duct 10 departs from said cylinder 1 axis and extends through cylinder 1 front end; Said helical duct 10 inwalls are matsurface, and this matsurface is made up of the annular burr that relies closely, and the spiral path line quadrature of each annular burr as shown in Figure 2 and said helical duct 10 is to increase the circumferential thrust of coating powder air-flow to helical duct 10 inwalls.
Above-mentioned electrostatic gun head, the port of export 12 of said helical duct 10 is a horn mouth, so that good diffusion space is provided for coating powder.
Above-mentioned electrostatic gun head is provided with sealing ring in the said rotatable joint 2, is a hermetic seal swivel joint.
Above-mentioned electrostatic gun head can be assemblied in the gun barrel mouth of common electrostatic gun, and Compressed Gas sprayed coating powder from gun barrel after, the powder air communication was crossed said helical duct 10 back ejections; Because helical duct 10 inwalls are matsurface, therefore, during powder airflow passes helical duct 10; To circumferentially promote helical duct 10, thereby force this electrostatic gun head rotation, in this process; The port of export of helical duct 10 will make the powder of ejection under centrifugal action, improve diffusivity around said cylinder 1 axis rotation, thereby obtain the better spraying uniformity; As shown in Figure 3; Dotted arrow has been illustrated the roughly sprinkling path of coating powder, and it had both had a circumferential diffusion motion, had an axial advancement motion again.
In addition, this electrostatic gun head is bascule as diffusion structure, therefore is difficult for laying dust.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
