Abstract

A device for powder coating of crevices is mainly a powder spraying chamber with a plurality of nozzles and electrode needles inside. The nozzles spray powder particles for coating on an article to be processed through a powder supplying system, and the electrode needles simultaneously perform corona discharging on the article to be coating-processed through a static generator, so that electrostatic charges generate on the article to be processed, accordingly effect of electrostatic attraction of the article to be processed can be used, the powder particles can be attached on surfaces of the crevices of the article to be processed deeply, and accordingly even and intact powder coating of the article to be processed can be achieved.

Description

The finedraw powder body coating is used device

Technical field

The utility model is the innovative design of relevant a kind of finedraw powder body coating with device; Especially a kind of order of finger treats that application processing object produces static electrification; And make powder be adsorbed in the electrostatic spraying design of processing object surface, be specially adapted to have the application of the processing object of small finedraw.

Background technology

Adopt thermosetting powder body coating know-why by this industry; Be derived from the recommendation of the one's nine six 0 from Europe; Because the used powder of application do not have the adding volatile solvent, do not have the effect of environmental protection so environment is not produced public hazards, also there are not the danger such as inflammability, explosivity of traditional application of spraying paint; More accord with the standard of construction safety health, adopted by relevant dealer.

And in the present every profession and trade powder body coating; Use the most extensively and popularize with electrostatic spray again, it roughly can divide into general charged and frictional electrification dual mode, and general charged method is for to be provided with electrode in spray gun gun barrel end; And by cathode voltage that high-voltage generator produced (pact-30KV to-between 100KV); Connect and to deliver to the terminal electrode of gun barrel, make be positioned at the lance tube end near air molecule produce ionization, and the application powder is just drawn anion when conduct is faster than ion under compressed-air actuated driving and electronegative; Positive electron on the coated article that this electronegative application powder just can be grounded attracts; And be formed with the powder coating of one deck, again via toasting thermoset processes together, to accomplish the work of application.Only this kind electric discharge will make and reach painting effect because corona discharge produces powerful space electric field, make powder can't get into faraday and be with the dead angle, and it is bad to cause the powder covering, locates like coated article back, depressed part and inside etc.Wherein so-called faraday's phenomenon; For in space electric field; Power line increases the phenomenon that the power line of density recess lowers in the tip, so powder depressed part more difficult to get access just, and makes the inequality of filming; Because of above-mentioned charged method has the shortcoming that is difficult to overcome, so be not suitable for the application of the big coated article spare of tool finedraw or variation in moulding.

In addition, a kind of electrostatic spraying method of frictional electrification is also arranged in the streets, for utilizing a kind of particles of powder and gun barrel, process and the phase mutual friction on its principle, make the induction of its powder particle produce electric charge, mat electrostatic attraction and the coated article that is attached to ground connection like nonconducting iron fluorine.This kind method is owing to be that indivedual frictions make it charged to powder; Therefore the electric-field intensity between spray gun and coated article a little less than; Though do not influence, has more excellent penetration power, because of it only depends on the mutual friction mutually between the tube wall of powder particle and gun barrel passage charged so more be not subject to Faraday effect during application; So the charged value of powder belt particulate is less and wayward, cause coating quality still desirable not to the utmost.

In view of this, the inventor is think of, the design team's system of grinding with great concentration to the shortcoming that said structure haves much room for improvement, and the phase can effectively be improved above-mentioned shortcoming, desires to grind the invention motivation of wound for the utility model.

Summary of the invention

The main purpose of the utility model is to provide a kind of finedraw powder body coating to use device, and order processing object produces static electrification, so that in each finedraw or groove of the deep enough machining object part of powder particle ability, reach the effect of complete and uniform external coating.

For reaching above-mentioned purpose; The utility model is mainly and is provided with one and can supplies to treat the powder spray chamber that application processing object is provided with, the powder-supply system of supply spray chamber powder eruption; And the power system of a generation electrostatic charge constitutes; It is characterized in that: this powder spray is indoor for being designed with a plurality of powder jet and sparking electrode pins that are provided with towards the processing object; And be connected to powder-supply system in the nozzle rear end by transfer pipeline, electrode needle is then joined by the electrostatic generator of electric wire and power system, makes electrode needle to processing the object corona discharge to discharge electric charge; Can make the processing object produce static by this, and make even and complete being coated with of powder particle of nozzle eruption invest the processing object surface.

The actual gain of the utility model; Be that design provides a kind of finedraw powder body coating to use device; Carry out the integrally formed shape application processing at outer surface and finedraw place thereof with the object that will have finedraw, the powder that application is used can get into the finedraw place because of the used powder of Electrostatic Absorption application, so that the operation back segment carries out heated baking again and is melted into lacquer painting; Have the effect that the protection workpiece is difficult for contacting with air fosterization, integral body also makes workpiece have beautiful outer top coat and increases aesthetic property.

Other characteristics of the utility model and specific embodiment can further be understood in the detailed description of following conjunction with figs..
