Description
Technical Field
The invention relates to the field of spraying tools, in particular to a manual electrostatic spray gun convenient for changing the color of sprayed powder.
Background
In many cases, the surface of a metal member needs to be coated to make the surface of the metal member have good corrosion resistance and more neat and beautiful. Therefore, a simple manual paint spraying or electrostatic spraying mode is usually adopted, and when the simple manual paint spraying is adopted, because the liquid paint is sprayed by a common spray gun, the condition of uneven paint flowing is easily caused on the surface of a workpiece, the result of uneven thickness of each part of a coating is finally caused, and the coating quality is poor. In view of the above, in the metal coating process with high requirements at present, it is required to perform coating by electrostatic spraying, that is, to spray powdery charged coating particles to a charged workpiece by an electrostatic spray gun, so that the coating particles are uniformly adsorbed on the surface of the workpiece, and then to perform high-temperature melting, leveling and curing processes, so that the coating is uniformly coated on the surface of the workpiece. The principle is as follows: the negative electrode is arranged in the electrostatic spray gun, the workpiece is grounded, the powdery coating particles are blown out of the electrostatic spray gun by the compressor, and are uniformly adsorbed by the workpiece after being electrified by the electrostatic generator at the muzzle. When an existing manual moving and static electric spray gun is used, several different colors are often required to be used for spraying, after powder of one color is sprayed, part of the powder can be remained in a powder channel of the spray gun, and after the remained powder is contacted with new powder, the powder can be polluted to influence the spraying quality.
Disclosure of Invention
The invention aims to provide a manual electrostatic spray gun aiming at the problems that the conventional manual static and dynamic electric spray gun in the background art is easy to adhere powder on the wall of a powder channel and is difficult to clean.
The technical scheme for realizing the purpose of the invention is as follows:
a manual electrostatic spray gun comprises a spray gun shell, a spray head, a high-voltage electrostatic generator, a powder pipeline and an electrode, wherein the spray head is arranged on the left side of the spray gun shell, the powder pipeline is a straight pipe with a smooth inner wall, the powder pipeline extends to the spray head from the right side of the spray gun shell, the right end of the powder pipeline extends to the outside of the spray gun shell, the right end of the powder pipeline is provided with a pipe joint connected with an external powder pipeline, the inner hole of the spray head and the powder pipeline are coaxially arranged, the electrode is arranged on the central axis of the inner hole of the spray head, the high-voltage electrostatic generator is arranged in the spray gun shell, a power line connector is arranged on the right side of the spray gun shell, a branch connector for introducing air is arranged on the pipe connector of the powder pipeline, residual powder in the powder pipeline is removed by introducing air, a wrench is arranged on the spray gun shell and is connected with a switch for controlling the high-voltage electrostatic generator and the powder pump.
In the above scheme, the high-voltage electrostatic generator is arranged in the handle of the spray gun shell.
In the above scheme, the outer side of the handle of the spray gun shell is provided with a fixing clamp for fixing the external powder pipeline and the external power line.
The invention has the following beneficial effects: according to the manual electrostatic spray gun, the powder pipeline is arranged to be the straight pipe, so that the material powder remained in the powder pipeline is reduced when the spray gun is used, the branch interface is arranged on the pipe connector, when the color of the material powder needs to be changed, air is introduced into the branch interface to clean the powder pipeline, and the residual powder in the powder pipeline is thoroughly cleaned. Through this kind of setting, can make in the spray gun use, it is more convenient to change the material powder, can prevent moreover that different colours from expecting the powder and mixing, promotes the spraying quality.
