Description

Technical Field

[0001] The utility model relates to the technical field of powder spraying machines, in particular to a powder spraying machine with a protective structure. Background Art

[0002] Electrostatic spraying refers to a coating method that uses the principle of corona discharge to make the atomized paint negatively charged under the action of a high-voltage DC electric field, and adsorbed on the surface of a positively charged substrate for discharge. The electrostatic powder spraying device uses a spray gun to spray powder. By making the dispersed powder ions negatively charged, the powder is coated on the surface of the workpiece under the action of electrostatic attraction, and then heated, melted and solidified into a film.

The utility model is provided with a good profile matching transmission structure, that is, a plurality of guide rollers are arranged on the front side of the base, and when the coating powder spraying work of the overall profile is carried out, the profile station can be quickly transmitted via the plurality of guide rollers. In the process of realizing the utility model, the inventor found that the prior art has the following problems: 1. The existing powder spraying machine mainly relies on the powder to adhere to the surface of the object under the action of static electricity, but the powder will float into the air at will, and long-term work in dust will affect the health of workers; 2. When the existing powder spraying machine is spraying powder on the profile, its powder spraying head can only move horizontally above the guide roller, and cannot be tilted, so the spraying effect on the side of the workpiece is poor and not comprehensive enough.
