Background
The water-base externally applied electrostatic spray gun is a spraying tool for coating surface, and is mainly used for coating metal surface.
The water-based external electrostatic spray gun has the working principle that a spray gun sprays paint from a nozzle and atomizes the paint into fine particles, a static needle of the electrostatic spray gun carries negative high-pressure ionized air to enable the paint particles to uniformly carry negative charges, and finally, coating particles are adsorbed on the surface of a sprayed workpiece with opposite electrostatic charges.
For the electrostatic spraying of the water paint, the traditional internal electrification electrostatic spraying needs to insulate the paint and a pipeline completely, and a high-voltage system must be disconnected during feeding, so that the practical production operation is inconvenient and the safety is not high.
SUMMERY OF THE UTILITY MODEL
In order to achieve the purpose, the utility model adopts the technical scheme that:
an external electric spray gun for spraying water paint comprises an insulating spray head main body, wherein a liquid cavity channel is arranged in the middle position in the insulating spray head main body, a high-voltage cable wiring pile is arranged at the right side position, close to the bottom, in the insulating spray head main body, and a conductive copper plate electrically connected with the high-voltage cable wiring pile is arranged at the position, outside the liquid cavity channel, in the insulating spray head main body;
the position that the left side of insulating shower nozzle main part is close to the outward flange can be dismantled and be connected with several and electrically conductive copper electric connection's electrode needle, static high pressure is leading-in through high tension cable wiring stake by outside electrostatic generator, and release by the electrode needle, insulating shower nozzle main part can guarantee except that static needle, there is not static release to outside air, thereby guarantee that the spray gun when the spraying, paint particle can all be full of the electric charge, and do not influence original fog type, can solve the defect of adding the interior electricity electrostatic spraying of waterborne coating and add the electricity electrostatic spraying more safely than in waterborne in the past, improve work efficiency greatly.
Furthermore, the left side of the insulating nozzle body is located at the position of the liquid cavity channel and is fixedly connected with an atomizing cap through a fastening cap, and the right side of the insulating nozzle body is located at the position of the liquid cavity channel and is in threaded connection with a rear fastening cover.
Further, the bottom of the insulating nozzle body is fixedly connected with a support rod through a bolt, and the support rod can be replaced by different lengths so as to be conveniently fixed on a machine arm or other spraying machines.
Furthermore, the number of the electrode needles is eight, and the electrode needles are distributed on the left side of the insulating spray head main body at equal angles so as to ensure that paint particles can be fully filled with charges.
The working principle and the beneficial effects are as follows: the high voltage is led in by an external electrostatic generator through a high-voltage cable wiring pile and is released by an electrode needle, the insulating spray head main body can ensure that no static electricity is released to external air except the electrostatic needle, so that paint particles can be fully charged when a spray gun is used for spraying, the original fog type is not influenced, the defect that the water-based paint is internally electrified for electrostatic spraying is overcome, and the water-based paint is safer than the water-based internally electrified electrostatic spray gun, and the working efficiency is greatly improved.
