Plasma surface treatment apparatus

Abstract

The invention relates to a plasma surface treatment device which comprises a shell, a plasma nozzle, a rotating neck, an insulator, a driving mechanism, an ionization mechanism, a metal member and an electrode. A power output shaft of the driving mechanism, the insulator and the ionization mechanism are respectively hollow structures. The metal member is arranged in the hollow structure of the insulator, and the metal member is a hollow annular structure. The electrode is arranged in the hollow portion of the metal member which is provided with two or more gas exhaust holes. The surfaces of the hole walls of the gas exhaust holes are disposed obliquely toward the direction of the plasma nozzle. The plasma surface treatment device of the present invention has the advantages of a more uniform spraying effect, less noises, effective reduction of loss and cost reduction.

Description

technical field [0001] The invention relates to plasma equipment, in particular to a plasma surface treatment device. Background technique [0002] Plasma, also known as plasma state. Substances in the plasma state have properties similar to those in the gaseous state, such as good fluidity and diffusivity. However, since the basic constituent particles of plasma are particles and electrons, it also has many properties different from gaseous state, such as good electrical conductivity and thermal conductivity. So the application of plasma is very extensive. With the continuous advancement of technology, the application fields of plasma rotary gun head are also very wide, including printing and packaging industry, digital industry and automobile industry, so the use of plasma spray gun is also increasing. [0003] The existing plasma rotary gun head has the following defects: there are fixed and static devices in the inner hole of the rotary head, and there are problems su...

AI Technical Summary

Problems solved by technology

[0003] The existing plasma rotary gun head has the following defects: that is, there are fixed and static devices in the inner hole of the rotary head, and there are problems such as easy drive failure.

The tilting nozzle means that the spray channel and the rotation axis of the plasma gun head form a certain angle, which can expand the spray area of ​​the sprayed plasma, but due to its low speed, the spraying effect is uneven and there are still problems such as large noise and easy heating.
