Abstract
The utility model discloses an electrostatic spraying circuit which comprises a main circuit. An electronic transformer formed by a power supply circuit, an oscillating circuit, a booster circuit and a high voltage output circuit is arranged in the main circuit; one end of the electronic transformer is connected with the wire inlet end of a power supply and the other end of the electronic transformer is connected with an output polar on a spraying gun; and a feedback circuit for controlling the power supply is connected between the power supply circuit and the booster circuit in the main circuit. According to the utility model, a discharge voltage and a discharge current which are required in the working process can be regulated by the signal condition of the feedback circuit; and the electrostatic spraying circuit can adapt to different environments and sprayed materials, so that paint is uniformly and comprehensively adsorbed to a coated metal surface and the product quality and production efficiency are improved.
Description
Technical field
The utility model relates to the electrostatic spraying apparatus technical field, is specifically related to a kind of electrostatic spraying circuit.
Background technology
Electrostatic painting process is to utilize static to be adsorbed on the surface of workpiece to powder, through the coating process of barbecue film forming.Electrostatic spray be coated article with ground connection as anode, equipment high-tension electricity grid connect negative high voltage as negative electrode; Form the high-voltage electrostatic field at two interpolars, negative electrode produces corona discharge, makes the coating particle of ejection charged; And further atomizing, repel each other the principle that there is a natural attraction between the sexes by the same sex; Make charged coating particle in the effect lower edge of electrostatic field power line direction absorption coated article, stick to a kind of process on the coated article after the discharge.The weak point of traditional electrostatic spraying circuit is: can not make automatic adjustment according to the change of spraying environment, go out because spraying is inhomogeneous through regular meeting, the phenomenon that need process once more takes place.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of environment for use that do not receive to influence, and spraying effect is good is applied in the electrostatic spraying circuit in the electrostatic spraying apparatus.
A kind of electrostatic spraying circuit comprises main circuit; Be provided with by power circuit in the said main circuit; Oscillating circuit, the electronic transformer that booster circuit and high-voltage output circuit constitute, an end of said electronic transformer is connected with power inleting terminal; The other end is connected with output stage on the spray gun, is connected with the feedback circuit that is used to control power supply between power circuit in the said main circuit and the booster circuit.
The utility model can come discharge voltage required in the adjusting work and electric current through the RST of feedback circuit, can adapt to varying environment and coated article, and coating evenly comprehensively is adsorbed on by the metal surface of application, has improved product quality and production efficiency.
