Production line for automatically coating profile steel and coating method thereof

Abstract

The invention discloses a production line for automatically coating a profile steel and a coating method thereof, wherein a suspension conveying line (2) runs through the central axis of a coating chamber (4). A loading mechanism (3) is installed on the front end of the coating chamber (4); and the suspension conveying line (2) on the back end of the coating chamber (4) is provided with a drying channel (5). A back output end of the drying channel (5) is connected with a cooling area (7); and an unloading mechanism (8) is installed behind the cooling area (7). By utilizing the head-to-tail closed loop suspension conveying line and the tandem type hanging manner of hanging multiple workpieces on one hanger, procedures such as loading, finishing coat spraying, priming paint spraying, drying, cooling, unloading and storing are all finished automatically, accordingly achieving the automatic spraying of the profile steel having a long length, and optimizing the conventional profile steel coating technology. By utilizing electrostatic spraying in association with the position and the angle of the spraying gun, the coating problem of coating dead angle at inside corners of the profile steel is solved better, accordingly improving the coating quality of the entire profile steel.

Description

technical field [0001] The invention relates to a spraying production line and a spraying method thereof, in particular to an automatic steel spraying production line and a spraying method thereof, and belongs to the technical field of painting. Background technique [0002] Section steel is widely used in industrial and civil buildings, bridges, ports, etc. The production volume is large, and the surface of the material is required to be painted. Since the section steel components used in construction are generally long (4-10 meters) and the weight of a single piece is relatively large, the surface protection of the section steel component materials mostly adopts traditional air or airless spray guns and manual spraying at fixed sites. The quality of artificial hand-sprayed film is not easy to control, the environment is polluted, the labor intensity of workers is high, the production cycle is long, the paint takes about a week to dry, and the production efficiency is lo...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the simple spraying production process of the existing section steel, the difficult control of the coating quality on the surface of the section steel, the dead angle of the spraying at the inner corner of the section steel, the low degree of automation of the spraying production process, the high labor intensity of workers, the long production cycle and the large environmental pollution, and The existing spraying production line has a simple structure and a single function, and the loading and unloading and conveying methods are not suitable for long steel components. Now we provide a reasonable structure, automatic degree, paint and time saving, and a good loading and unloading and conveying method. It is an automatic spraying method for section steel that satisfies the coating requirements of longer section steel components, and can better solve the dead angle of spraying at the inner corner of section steel, and thus provides an automatic spraying production line
