Problems solved by technology

[0008] (1) It solves the problem that the rotary cup requires many workpieces, many manufacturing and assembly processes, and if the processing accuracy is not high, it will affect the atomization effect during use;
[0009] (2) It solves the problem that the spray area of ​​the V-shaped cup mouth part is large, which makes the mist disperse and the waste of the coating liquid is large;
[0010] (3) Solve the problem that the electrostatic nozzle is not resistant to corrosion

Embodiment Construction

[0026] Combine below Figure 2 to Figure 3 , the present invention is further described:

[0027] Such as figure 2 As shown, a high-speed pneumatic rotary cup type corrosion-resistant electrostatic spray head includes: rotary cup body 22, rotary cup liquid nozzle 24, liquid delivery device 25, liquid outlet 26, baffle plate, support plate and liquid inlet 27. The cup body 22, the baffle plate, the supporting plate and the liquid spout 24 of the rotary cup are processed into the integrated part 23 of the cup body, the baffle plate, the supporting plate and the spout by a piece of bar stock. When the rotary cup body 22 , the baffle plate, the support plate and the rotary cup liquid nozzle 24 are processed into one piece 23 , the processing is simple, the matching error between the components is reduced, and the processing accuracy is guaranteed.

[0028] The mouth of the cup body 22 is a U-shaped cup 21 . The U-shaped cup mouth can make the mist of the coating liquid more co...

Abstract

A high speed pneumatic rotary cup corrosion-resistant static nozzle comprises a rotary cup body, a rotary cup liquid jet, a liquid delivery device, a liquid outlet, a traverse baffle, a support plate and a liquid inlet. The rotary cup body, the traverse baffle, the support plate and the rotary cup liquid jet are manufactured into an integral piece of the cup body, the traverse baffle, the support plate and the jet by a barstock. The nozzle has the advantages of simple part processing, reduced mismatch error between the components, guaranteed machining precision, improved utilization factor of masking liquid, corrosion resistance and the like.

Description

technical field [0001] The invention relates to an electrostatic spray head for painting and powder spraying, in particular to a high-speed pneumatic rotary cup type electrostatic spray head. Background technique [0002] Electrostatic spraying is a new technology in the modern spraying industry, and it is widely used in coating industries such as spray painting and powder spraying. [0003] The current electrostatic spraying is roughly divided into two types: air atomization spraying and rotary cup atomization spraying. The spray gun used in air atomization spraying is similar to that of ordinary compressed air spray guns, but its structure is completely different. The whole spray gun except The handle, spray nozzle and pole needle are all made of nylon, and the negative high pressure is connected to the paint spray nozzle and pole needle. At the spray nozzle and pole needle, the paint atomized particles in the electric field are split by the uneven and strong electric fie...
