Intelligent spraying process for metal chair processing and production

Abstract

The invention discloses an intelligent spraying process for metal chair processing and production. The intelligent spraying process comprises the following steps of firstly, cleaning a metal chair, wherein the cleaning sequence comprises washing with water, oil removing cleaning, acid pickling and washing with water again; secondly, carrying out drying and cooling; thirdly, carrying out grinding and thermal spraying, specifically, carrying out grinding, polishing and thermal spraying on the surface of the metal chair at the same time through a grinding and thermal spraying device; fourthly, controlling temperature and humidity, specifically, controlling the temperature of the surface of the metal chair, and controlling the humidity in a spraying chamber; fifthly, carrying out paint surface primary spraying, specifically, carrying out paint surface primary spraying on the surface of the metal chair through a spraying device; sixthly, measuring the paint surface thickness, specifically, measuring the paint surface degree of the surface of the metal chair V through a coating thickness gauge; and seventhly, carrying out flow control and re-spraying, specifically, carrying out re-spraying on the surface of the metal chair V through the spraying device, wherein a PLC triggers a flow control device according to paint surface thickness data during re-spraying so as to carry out flow control on the spraying device. The intelligent spraying process can avoid metal dust pollution and is uniform in paint layer thickness after spraying.

Description

technical field [0001] The invention mainly relates to the technical field of metal chair preparation, in particular to an intelligent spraying process for the processing and production of metal chairs. Background technique [0002] The surface of the metal chair needs to be sprayed with paint when it is prepared. The paint can not only protect the metal surface, but also decorate and beautify the metal chair. [0003] According to a metal surface spraying process provided by the patent document with the application number CN201911420600.2, it can be known that the process includes the following steps: degreasing, cleaning and degreasing the surface of the metal surface material; grinding, cleaning the surface of the metal surface material Grinding and polishing; epoxy primer, epoxy primer on the polished metal surface; grinding, surface grinding of the metal surface with epoxy primer; colored topcoat, the polished metal surface There is a colored topcoat on the material, p...
