Embodiment Construction

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Example. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] Please join again figure 1 As shown, in the process of high-voltage electrostatic powder spraying, the principle of the Faraday cage electrostatic shielding effect around the recessed area is as follows:

[0036] Negatively charged free ions are generated when the spray gun head discharges, so that there is a cloud composed of charged powder particles and negatively charged free ions between the spray gun head and the component to...

Abstract

Provided are an electrostatic powder spray coating device and a spray coating method therefor. The device comprises a jet stream generating element (21), an electric field generating element (22) and an electric field shaping element (23), wherein the jet stream generating element (21) is used to produce a jet stream carrying electrically charged powder particles, the electric field generating element (22) is used to produce an electrostatic force field for guiding the electrically charged powder particles between the electric field generating element (22) and an element (30) to be spray-coated, and the electric field shaping element (23) is used to shape the electrostatic force field so as to reduce the Faraday cage electrostatic shielding effect of the electrostatic force around a recessed region (31) of the element (30) to be spray-coated. The spray coating device can improve the powdering depth in the recessed region (31).

Description

technical field [0001] The invention relates to the technical field of high-voltage electrostatic powder spraying, in particular to an electrostatic powder spraying device and a spraying method thereof. Background technique [0002] figure 1 It is a working schematic diagram of a high-voltage electrostatic powder spray gun in the prior art. see figure 1 As shown, when the high-voltage electrostatic powder spray gun 10 is spraying powder, it applies high-voltage electricity to the spray gun head 11 to discharge. When the spray powder mixed with the high-pressure jet airflow passes through the spray gun head 11, it is induced to be negatively charged to form a charged powder. The particles fly to the component to be sprayed 13, at this time the component to be sprayed 13 is grounded to form a positive pole, thereby generating an electrostatic force field between the spray gun head 11 and the component to be sprayed 13, and the charged powder particles are adsorbed on the com...
