Problems solved by technology

[0002] In the process of using the spray gun, when the applied static electricity is too strong, it will cause the phenomenon of sparking, which will cause unsafe use, so it will lead to the control of the electrostatic intensity in the process of using the spray gun, and the process of controlling the electrostatic intensity Just can't meet the needs of electrostatic strength, so, in the prior art, need a kind of under the situation of providing enough electrostatic strength badly, the electrostatic spraying spray gun that is difficult to produce the phenomenon of electrostatic ignition

Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] The object of the present invention is to provide a method and system for controlling the voltage of an electrostatic spraying gun under the condition that sufficient electrostatic strength is provided, and the phenomenon of electrostatic sparking is not easy to occur.

[0045] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjun...

Abstract

The invention discloses an electrostatic spraying spray gun voltage control method and system. The electrostatic spraying spray gun voltage control method includes the steps that sampling data of output currents of a spray gun in the electrostatic spraying process are obtained in a timing manner; the current set value and the voltage set value set by a user of the spray gun are obtained; and the output voltage of the spray gun in the electrostatic spraying process is calculated according to the sampling data, the current set value and the voltage set value. The output voltage of the spray gunis controlled so that the fire striking phenomenon caused by the too strong spray gun static can be effectively inhibited, and the spray gun can work in a state that enough static currents can be generated and static fire striking is not likely to be generated.

Description

technical field [0001] The invention relates to the field of electrostatic spraying, in particular to a method and system for controlling voltage of an electrostatic spraying spray gun. Background technique [0002] In the process of using the spray gun, when the applied static electricity is too strong, it will cause the phenomenon of sparking, which will cause unsafe use, so it will lead to the control of the electrostatic intensity in the process of using the spray gun, and the process of controlling the electrostatic intensity Just can't satisfy the requirement of electrostatic intensity, so, in the prior art, under the situation of providing enough electrostatic intensity, the electrostatic spray gun that is difficult to produce the phenomenon of electrostatic ignition is badly needed. Contents of the invention [0003] The object of the present invention is to provide a method and system for controlling the voltage of an electrostatic spraying gun under the condition...
