Abstract

The invention provides an electrostatic powder spraying device and a spraying method of the electrostatic powder spraying device. The electrostatic powder spraying device comprises a jet airflow generating element, an electric field generating element and an electric field shaping element, wherein the jet airflow generating element is used for generating jet airflow carrying electrified powder particles, the electric field generating element is used for generating an electrostatic force field for guiding the electrified powder particles between the electric field generating element and an element to be sprayed, and the electric field shaping element is used for shaping the electrostatic force field so as to reduce the Faraday cage electrostatic shielding effect of electrostatic force around a concave area of the element to be sprayed. Due to the mode, the problem that no power can be applied to the concave area of the element to be sprayed because of the Faraday cage electrostatic shielding effect can be solved, and the powder applying depth in the concave area is increased.

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...
