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

Abstract

The invention relates to the technical field of electrostatic spraying, in particular to a disc type electrostatic spraying device and process for low-temperature quick-drying water-based paint. The disc type electrostatic spraying device comprises a device body and an electric telescopic rod. The device body comprises a main bottom plate, and an auxiliary bottom plate is fixedly installed at one end of the main bottom plate. The electric telescopic rod is connected to the portion, on one face of the auxiliary bottom plate, of the main bottom plate, and an electrostatic sprayer body is fixedly installed at one end of the electric telescopic rod. According to the disc type electrostatic spraying device and process for low-temperature quick-drying water-based paint, a U-shaped strip plates and clamping tooth sleeves are arranged, so that clamping tooth strips are engaged with the clamping tooth sleeves, a U-shaped conveying chain body can drive a workpiece to rotate during movement, when the workpiece is subjected to electrostatic spraying, paint can be more evenly attached to the whole workpiece, then the spraying quality of the workpiece is improved, the situation of uneven spraying is reduced, the qualified rate of the workpiece is increased, the production cost of enterprises is indirectly reduced, and follow-up personnel maintenance and detection are indirectly reduced.

Description

technical field [0001] The invention relates to the technical field of electrostatic spraying, in particular to a disc-type electrostatic spraying device and process for low-temperature quick-drying water-based paint. Background technique [0002] Electrostatic spraying refers to the coating method that uses the principle of corona discharge to make the atomized paint negatively charged under the action of a high-voltage direct current electric field, and adsorbed on the surface of the positively charged substrate to discharge. Electrostatic spraying equipment consists of a spray gun, a spray cup, and a high-voltage power supply for electrostatic spraying. The fixed electrostatic spraying equipment which is widely used is usually combined with the 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 th...

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
