Electrostatic spraying device for bamboo products and spraying process of electrostatic spraying device

Abstract

The invention relates to an electrostatic spraying device for bamboo products. The electrostatic spraying device comprises a conveying mechanism and a disk spray gun, wherein the conveying mechanism is used for conveying the bamboo products to be sprayed, and in contact with the ground and takes the shape of omega; one or more hoisting tools are arranged on the conveying mechanism at intervals; the upper end of each hoisting tool is hinged to the conveying mechanism, and the bamboo products to be sprayed are mounted at the lower ends of the hoisting tools; the disk spray gun is used for spraying the bamboo productd and is vertically arranged at the middle part of the conveying mechanism; the disk spray gun is connected with a high-voltage power supply, a paint feeding device, a driving device for controlling the disk spray gun to rotate and a lifting device for controlling the disk spray gun to move up and down. The electrostatic spraying device has the benefits that the utilization ratio of paint is increased greatly and can reach 85%-90% or above; the quality of a sprayed product is good, a coating formed on a surface is uniform, flat, smooth and rich in paint film; the spraying efficiency is high, so that the electrostatic spraying device is suitable for large-batch automatic flow line production.

Description

technical field [0001] The invention relates to the field of bamboo product processing, in particular to an electrostatic spraying device for bamboo products. Background technique [0002] Electrostatic coating technology is widely used on metal products. The essence of electrostatic coating on metal products is to make the paint particles negatively charged, and to make the surface of the coated metal products positively charged. The mixture of paint particles sprayed from the nozzle of the spray gun and compressed air and the air around the electrode are ionized (negatively charged) by high-voltage static electricity, and the metal product workpiece passes through the hanger and passes through the conveying link (ground electrode), so that there is a gap between the spray gun and the workpiece An electric field station is formed between them, so that the powder reaches the surface of the workpiece under the double push of the electric field force and compressed air pre...

AI Technical Summary

Problems solved by technology

[0003] Bamboo products are generally considered as poor electrical conductors. Due to the fact that the base material of bamboo products cannot be charged and the products vary greatly, the influence of environmental factors on coating is complicated. At present, there are still some technical problems in electrostatic coating that have not been completely resolved.
