Problems solved by technology

[0004] For this kind of electrostatic spray gun, it can only spray smoke-like paint powder, and in the actual spraying process, sometimes it is necessary to spray some extremely small parts. There is no fine channel guide path inside the spray gun, so a good paint concentration effect cannot be achieved, and the stab spray effect cannot be achieved

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the drawings and embodiments:

[0018] in figure 1 , figure 2 In the illustrated embodiment, the piercing spray gun includes a gun handle 2 and a barrel 1. A trigger 3 is provided at the gun handle 2, and the trigger 3 controls the start of the electrostatic spray gun, and is electrically related to the air source and the electrostatic generation structure; The barrel 1 includes an annular passage 11 and a narrow tube passage 12. The annular passage 11 is provided with a corona wire 13 parallel to the axis of the barrel 1, and the annular passage 11 passes through a paint conduit 110 and a compressed air source. It is connected to a paint powder container (not an improvement of the present invention, not shown), and the thin tube passage 12 is connected in series with a solenoid valve 121 and then only connected to a compressed air source through a thin air flow conduit 120.

Abstract

The invention discloses a spray gun with a spot spraying function, which comprises a grip and a gun pipe. A trigger is arranged on the grip. The gun pipe comprises an annular passage and a thin tubular passage, a corona wire parallel to the axis of the gun pipe is arranged in the annular passage, the annular passage is connected with a compressed air source and a spray powder container, and the thin tubular passage is connected with the compressed air source after being connected with an electromagnetic valve in series. The spray gun can not only be used for atomizing but realizing fine spot spraying effect.

Description

Technical field [0001] The invention relates to a spray gun in the field of metal coating, in particular, an electrostatic spray gun that uses compressed gas to drive paint powder, including a gas source and an electrostatic generating structure. Background technique [0002] For metal components, in most cases, the surface of the metal component needs to be painted to make the surface of the metal component have good anti-corrosion performance and make it more tidy and beautiful. For this reason, simple manual spraying or electrostatic spraying is usually used. When simple manual spraying is used, because the ordinary spray gun sprays liquid paint, it is easy to cause uneven paint flow on the surface of the workpiece, which will eventually cause all parts of the coating The result of uneven thickness is poor coating quality. [0003] In view of the above reasons, in the current high-demand metal coating process, electrostatic spraying is required for coating, that is, the electr...
