Abstract
The utility model relates to a magnetic control electrostatic powder spray gun, comprising a spray gun body, a powder channel, a discharge electrode, a plurality of high-voltage cables, and a diffuser arranged at the head of the discharge electrode. A plurality of multitude permanent magnets are positioned at the side of the powder channel near the head end.. A spraying diameter controller is sleeved outside the tubular body and can slide along the outer part of the tubular body. The utility model has the advantages of high charged rate of powder, high powder spraying ratio, even coating of spraying surface of the workpieces and powder saving.
Description
The utility model relates to a kind of electrostatic powder paint gun, and especially a kind of charged probability of powder that can make improves, sprays uneven magnetic control electrostatic powder paint gun greatly.
In the external coating operation of various workpiece, because the effect of electrostatic spraying is better, it is increasingly extensive therefore to utilize electrostatic powder paint gun to carry out application.Existing electrostatic powder paint gun generally has two kinds of outer charged or interior charged formulas.As shown in Figure 1, the termination portion of spray gun body 1 is an air diffuser 6, is provided with sparking electrode 2 in the close end, and body 1 is mainly the powder channel 3 of powder, and handle portion 5 is power supply, the powder break-make position of gauge tap high-tension cable 4.The spray gun electrode 2 of interior charged formula is positioned at powder channel 3, and the charged rate of its powder is extremely low, present less application.The sparking electrode of outer charged formula spray gun is the single needle form, and the concrete structure schematic diagram as shown in Figure 2.The front portion of the termination portion air diffuser 6 of spray gun body 1 is a sparking electrode 2, and body 1 is mainly the powder channel 3 of powder, and handle portion 5 is power supply, the powder break-make position of gauge tap high-tension cable 4.In the use, sparking electrode 2 energisings of needle point formula make powder charged, and charged powder is sprayed onto on the surface of workpiece.Because the electron beam after the discharge can not be strapped near the electrode, so the charged rate of powder is not high.Have again, do not have the qualification of spraying area near the existing sparking electrode, therefore spray inhomogeneous, and the diameter of uncontrollable spraying, and the waste of powder is also bigger.
The purpose of this utility model is to provide a kind of magnetic control electrostatic powder paint gun, and the charged rate of its powder is higher, spraying powder utilization height.
Another purpose of the present utility model is to provide a kind of magnetic control electrostatic powder paint gun, and the surface coating of its spraying is even, can also save powder.
The purpose of this utility model is achieved in that a kind of magnetic control electrostatic powder paint gun, and it comprises the air diffuser at spray gun body, powder channel high-tension cable and termination portion sparking electrode place, and the powder channel side of wherein said body proximal end head is provided with magnet.
Described magnet is the multipole permanent magnetic iron more than.
Described body tubular outer cover is provided with can be along the spraying diameter controller of body tubular slide outside.
According to the technique scheme analysis as can be known, the utlity model has following advantage:
1, owing to the multipole magnet that is provided with at powder channel, make the charged rate of powder be further enhanced about 20%.
2, the coating uniformity of surface of the work is improved greatly, save powder about 10%.
3, sparking electrode is parallel with surface of the work, therefore is difficult for puncturing the bisque surface, can not produce spark discharge.
Below in conjunction with accompanying drawing and concrete implementer's case the utility model is described in further detail.
Fig. 1 is the prior art structural representation;
Fig. 2 is another kind of prior art structural representation;
Fig. 3 is the structural representation of the utility model improvement part;
As shown in Figure 3, the utility model is a kind of magnetic control electrostatic powder paint gun, and it comprises spray gun body 1, powder channel 3, the air diffuser 6 at high-tension cable 4 and body end head sparking electrode 2 places.Primary mixture arrives in the air diffuser 6 by powder channel 3, and powder is to radially scattering, and slows down and atomizes, and increase powder in time that high electric field region was detained.Improvement of the present utility model is: powder channel 3 sides at the body proximal end head are provided with magnet 7, and magnet be multipole permanent magnetic iron 7 ' more than one.Like this.Because multipole permanent magnetism 7,7 ' effect, with the electronics behind the corona discharge in the air be strapped in sparking electrode 2 near, increased the collision probability of electronics and powder greatly, the charged rate of powder is further improved, thereby has improved the powder utilization that sprays.In addition, be provided with spraying diameter controller 8 in body 1 tubular outer cover, spraying diameter controller 8 can so can control powder easily at the spraying diameter that is coated with on the workpiece, not only can make spraying evenly, and can save powder along body 1 tubular slide outside.
Claims (3)
