Abstract
The invention discloses a spiral tubular spray gun tube and is applied to the field of metal coating electrostatic spraying. The spiral tubular spray gun tube comprises a straight spiral tube, wherein an inlet end which is connected with a gun body is arranged at the rear end of the straight spiral tube; an outlet end is arranged at the front end of the straight spiral tube; a spiral corona line which extends along a spiral path of the straight spiral tube is arranged in the straight spiral tube; and the corona line is electrically connected with a static electrode of the gun body. The contact length and the contact time of coating powder and the corona line in the spray gun are greatly increased by using the spiral tubular spray gun tube, so that the electrified effect of the coating powder is greatly increased.
Description
Technical field
The present invention relates to a kind of electrostatic gun in the coated metal field, especially, relate to the structure of gun barrel 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, and workpiece connects another utmost point of power supply, and the powder type coating prepn particle is blown out by compressor in electrostatic gun, through the electrostatic generator of muzzle charged after, make it evenly to be adsorbed by workpiece.
In electrostatic gun, its electrostatic generator makes coating powder charged through corona wire usually, and this kind corona wire is along the gun tube axis setting, coating powder when flowing through gun barrel, electrostatic charge on the corona tape; Yet, because present spray gun gun barrel is straight tube, therefore, its corona wire that length is set is very limited, the contact length of coating powder and corona wire is shorter, and can't guarantee the electrification time fully grown, therefore, the charged effect of coating powder is comparatively limited.
Summary of the invention
In order to address the above problem; The object of the present invention is to provide a kind of helix tube type lance tube; This lance tube can improve the contact length and the time of contact of coating powder and corona wire in the spray gun greatly, thereby improves the charged effect of coating powder largely.
The technical solution adopted for the present invention to solve the technical problems is: this helix tube type lance tube comprises straight helix tube, and said straight helix tube rear end is the entrance point that joins with the rifle body, and front end is the port of export; Be provided with the spirality corona wire that extends along this straight helix tube spiral path in the said straight helix tube, said corona wire and rifle body electrostatic attraction electrode are electrically connected.
As preferably, the said port of export is horn mouth, so that good diffusion orient space to be provided to coating powder.
As preferably, said straight helix tube inwall is made up of the high-temperature insulation pottery, thereby it is charged used for coating powder that most of electrostatic charge all is restrained in the pipe.
Beneficial effect of the present invention is: this helix tube type lance tube is owing to adopt straight spiral tube structure; With respect to the ordinary straight gun barrel; Its gun barrel path prolongs greatly, therefore, can hold the very corona wire of length; The contact length and the time of contact of coating powder and corona wire are improved greatly, thereby improve the charged effect of coating powder largely.
Description of drawings
Fig. 1 is the structural representation of an embodiment of a kind of helix tube type lance tube of the present invention.
Among the figure: 1, straight helix tube; 10, the port of export; 11, entrance point; 2, corona wire; 21, fixed support; 3, rifle body.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
In the embodiment shown in fig. 1, this helix tube type lance tube comprises straight helix tube 1, and said straight helix tube 1 rear end is the entrance point 11 that joins with rifle body 3, and front end is the port of export 10; Be provided with the spirality corona wire 2 that extends along this straight helix tube 1 spiral path in the said straight helix tube 1, said corona wire 2 is fixed in the straight helix tube 1 through fixed support 21, and said corona wire 2 is electrically connected with rifle body 3 electrostatic attraction electrodes.
Above-mentioned helix tube type lance tube, the said port of export 10 is horn mouth, so that good diffusion orient space to be provided to coating powder.
Above-mentioned helix tube type lance tube, said straight helix tube 1 inwall is made up of the high-temperature insulation pottery, thus it is charged used for coating powder that most of electrostatic charge all is restrained in the pipe.
Above-mentioned helix tube type lance tube is owing to adopt straight spiral tube structure; With respect to the ordinary straight gun barrel; Its gun barrel path prolongs greatly, therefore, can hold the very corona wire 2 of length; The contact length and the time of contact of coating powder and corona wire 2 are improved greatly, thereby improve the charged effect of coating powder largely.
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.
