Description
Technical field
The present invention relates to a kind of static nozzle that sprays paint and dust, especially relate to a kind of high speed pneumatic rotary cup static nozzle.
Background technology
Electrostatic spraying is a new technology in the modern spraying industry, and it is widely used in spraying paint and coating industry such as dust at present.
Existing electrostatic spraying roughly is divided into the spraying of air atomizing formula and revolves two kinds of glass atomization type sprayings, the used spray gun of air atomizing formula spraying sprays similar with common used compressed ir spray gun, but its version is distinct, whole spray gun removes handle, painting nozzle and utmost point pin are outside the metal, all other is a nylon products, negative high voltage just turns on painting nozzle and the utmost point pin, coating is under compressed-air actuated effect, be spray pattern, penetrate, be incident upon painting nozzle mouth and utmost point pin place by painting nozzle, the paint atomization particle of electric field, be subjected to the splitting action of inhomogeneous highfield again, thereby further atomizing and charged becomes " ion lacquer grain group "." ion lacquer grain group " under the effect, guide polarity surface of the work adsorbs neutralization in electric field force blast injection power (same direction), and this has just constituted the electrostatic spraying of air atomizing formula.The rotary cup electrostatic spraying is to utilize to have the metal cup that sharpened edge rotates at a high speed, revolving connection negative high voltage static on the cup axle, the inwall that revolves cup is because rotation, coating is subjected to action of centrifugal force, to diffusion all around, thereby forms uniform filminess, and get rid of to revolving rim of a cup stream, stream gets rid of to the coating that revolves rim of a cup, is subjected to the splitting action of forceful electric power field force again, and further atomizing is paint particles.Meanwhile, paint particles has also obtained electric charge, becomes negative electrical charge lacquer grain, and the rapid guide polarity of lacquer population workpiece absorption neutralization under the effect of electric field force is so coating just firmly is adsorbed on the surface of the work equably.
The scope of application of electrostatic spraying at present mainly is the industry of spraying paint, dusting, so most spray gun, the shower nozzle selling on the market now and produce and revolve cup and all be applicable to spray paint and dust, but to some special industries, as the liquid coating that contains the acid medium of inorganic acid itself has stronger corrosivity because of its masking liquid, thereby these spray guns, shower nozzle and revolve the cup material and structure inapplicable, in use or not corrosion-resistant, service life is short, or atomizing effect is bad, influence the uniformity of Workpiece painting, or cause the wastage of masking liquid big.
As shown in Figure 1: at present, revolving cup is broadening formation or V-type mostly, comprises that revolving a glass main body (1), attaching nut (2), deflection plate (3), gripper shoe (4), conveying pipeline (5), rotating shaft (6) and spray orifice parts such as (7) combines.Coating or masking liquid tangentially fly to and revolve a glass main body (1) inwall through conveying pipeline (5) ejection during work, and revolving under the cup effect of rotating at a high speed, coating or masking liquid atomize thereupon.
But this structure to revolve the required workpiece of cup many, make, assembly process is many, if can influence atomizing effect during the not high use of machining accuracy.Simultaneously when work V-type rim of a cup part masking liquid fly that to get rid of area big, haze is disperseed, might cause the masking liquid wastage big like this, and the workpiece uniformity is bad.
Summary of the invention
The present invention has designed a kind of high speed pneumatic rotary cup corrosion-resistant static nozzle, and it has solved following technical problem:
(1) solved that to revolve the required workpiece of cup many, made, assembly process is many, if the problem of machining accuracy is not high when can influence using atomizing effect;
What (2) solved V-type rim of a cup part masking liquid flies that to get rid of area big, makes haze disperse the problem that the masking liquid wastage is big;
(3) solved the not corrosion resistant problem of static nozzle.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of high speed pneumatic rotary cup corrosion-resistant static nozzle comprises; Revolve a glass cup, revolve a glass liquid spout, liquid transporting apparatus, liquid outlet, deflection plate, gripper shoe and liquid-inlet.Revolve a glass cup, deflection plate, gripper shoe and revolve glass liquid spout and be processed into cup, deflection plate, gripper shoe and spout integral piece by a bar.
The rim of a cup that revolves glass cup revolves cup for the U type.
Electric injector is made with corrosion resistant Titanium or titanium alloy.
Deflection plate is designed to the flywheel shape.
This high speed pneumatic rotary cup corrosion-resistant static nozzle compared with prior art has following beneficial effect:
(1) since the present invention will revolve a glass cup, deflection plate, gripper shoe and revolve glass liquid spout and be processed into cup, deflection plate, gripper shoe and spout integral piece by a bar, can realize that component processing is simple, reduce the mismatch error between the sub-assembly, the advantage of assurance machining accuracy.
(2) revolve cup because the rim of a cup that the present invention will be revolved glass cup is designed to the U type, when revolving cup work, can make the haze of masking liquid concentrated, be difficult for causing dispersing of masking liquid than the V-type rim of a cup, help improving the utilization rate of masking liquid, cut the waste, particularly use valuable coating, can save cost.
(3) because the present invention makes electric injector with corrosion resistant Titanium or titanium alloy, can go for having corrosive masking liquid environment such as hydrochloric masking liquid so that the workpiece corrosion resistance is good.
