Disc-type electrostatic spraying device and process for low-temperature and quick-drying water-based paint

Abstract

The present invention relates to the field of electrostatic spraying technology, in particular to a disc-type electrostatic spraying device and process for low-temperature, quick-drying water-based paint, comprising: a main body of the device, the main body of the device includes a main base, and an auxiliary base is fixedly installed at one end of the main base. Bottom plate; an electric telescopic rod, the electric telescopic rod is connected to the main bottom plate on one side of the auxiliary bottom plate, and one end of the electric telescopic rod is fixedly installed with an electrostatic nozzle body. The present invention is provided with a U-shaped bar and a tooth sleeve, so that the tooth bar and the tooth sleeve are engaged with each other, so that the U-shaped conveyor chain body can drive the workpiece to rotate when it moves, so that the workpiece is statically charged. When spraying, the paint can be more evenly attached to the workpiece as a whole, thereby improving the spraying quality of the workpiece, reducing the occurrence of uneven spraying, increasing the pass rate of the workpiece, and indirectly reducing the production cost of the enterprise and the subsequent Personnel maintenance and testing.

Description

technical field [0001] The invention relates to the technical field of electrostatic spraying, in particular to a disc-type electrostatic spraying device and a process for low-temperature quick-drying water-based paints. Background technique [0002] Electrostatic spraying refers to a coating method that uses the principle of corona discharge to make the atomized paint negatively charged under the action of a high-voltage DC electric field, and adsorbed on the surface of the positively charged substrate for discharge. Electrostatic spraying equipment consists of spray gun, spray cup and high-voltage power supply for electrostatic spraying. The stationary electrostatic spraying equipment that is widely used is usually matched with a suspension conveying device to form a continuous coating production line. In this case, the operator's work is limited to the preparation and loading and unloading of the painted workpiece, as well as the regulation and care of the equipment, etc...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of low-temperature fast-drying water-based paint disc-type electrostatic spraying device and technology, to solve the above-mentioned background technology proposed in order to complete the turn-over action of strip work and the spraying time that allows both sides to be subjected to approximately the same, The turning mechanism is generally set at the arc-shaped apex of the Ω-shaped or U-shaped conveying device, but in this process, due to factors such as the conveying device's conveying speed, turning over, and residence time, the two sides of the side of the strip-shaped workpiece or near the side are often The paint is not balanced enough, which affects the pass rate of the final product, increases the production cost of the enterprise, and also leads to the need to occupy a certain amount of human resources for inspection and repair in the later stage
