Abstract
The utility model relates to a spiral spray gun pipe, which is applied to the field of electrostatic spraying in metal coating. The spray gun pipe comprises a straight spiral pipe, wherein the rear end of the straight spiral pipe is an inlet end connected with a gun body; the front end of the straight spiral pipe is an outlet end; and a spiral corona wire which extends along a spiral path of the straight spiral pipe is arranged in the straight spiral pipe and is electrically connected with an electrostatic electrode of the gun body. By the spray gun pipe, the contact length of coating powder in a spray gun and the corona wire can be greatly increased, and the contact time of the coating powder and the corona wire can be greatly prolonged, so that the electrification effect of the coating powder is improved to a large extent.
Description
Technical field
The utility model relates to a kind of electrostatic gun in the coated metal field, especially, relates 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 purpose of the utility model 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 utility model solves the technical scheme that its technical problem adopted: 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.
The beneficial effect of the utility model 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 the utility model helix tube type lance tube.
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 utility model 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 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.
