Problems solved by technology

But this method has the following disadvantages: ① powder is easily adsorbed in the gap between the external multi-needle ring and the outer diameter of the spray gun barrel, and it is not easy to clean up
②The external multi-needle ring and the grounding loop rod are easy to collide and damage, and it is not easy to clean

Abstract

The invention discloses an electrostatic powder spray gun with a built-in ion collector, which mainly comprises an electrostatic spray gun tube, an integrated spray gun locking cap, a discharge needle seat, a discharge needle, a flat spray flow guiding port and an ionic collecting ring and is characterized in that the ionic collecting ring is inlaid into the front part of the integrated spray gun locking cap, the outer side edge of the ionic collecting ring is exposed, and the rest part of the ionic collecting ring is inlaid into the inner part of the integrated spray gun locking cap. The electrostatic powder spray gun is easy to clean, has reasonable and compact structure and can completely avoid the problem of power concealment inside gaps; and a wire guiding passage is arranged on the side face of the integrated spray gun locking cap, a ground-return circuit lead wire penetrates inside the wire guiding passage, and one end of the ground-return circuit lead wire is electrically connected with the ionic collecting ring, therefore, the grounding reliability is high and the stability of a spraying process is improved.

Description

Technical field: [0001] The invention mainly relates to an electrostatic powder spray gun with a built-in ion collector. Background technique: [0002] During electrostatic powder spraying, the powder on the nozzle of the spray gun is sprayed out by pneumatic conveying power, and corona charging is carried out at the front of the spray gun muzzle. Generally, the corona charging electrode is usually connected to a negative high voltage generator in the range of (10-110) KV , during powder spraying, the tip of the discharge needle releases free ions to the workpiece, most of the charged ions in the electrostatic field will charge the powder particles in the atomized state, and the remaining small part of the free ion charges will not charge the powder particles, but this part Free ions will also fly to the surface of the workpiece, because the workpiece is grounded, and the potential difference between the two will inevitably lead to the adsorption of some free charged ions on...
