Paint spraying device for irregular curved surface metal

Abstract

The invention relates to the technical field of paint spraying equipment, in particular to a paint spraying device for irregular curved surface metal. The paint spraying device comprises a supportingtable and a spray gun; the supporting table comprises a circular supporting plate and supporting legs evenly arranged at the bottom of the circular supporting plate in the circumferential direction, and a first electric push rod and a second electric push rod are fixedly arranged on the two sides of the circular supporting plate correspondingly; the tops of the first electric push rod and the second electric push rod are fixedly connected with a first mounting sleeve body and a second mounting sleeve body correspondingly, a mounting block used for mounting the paint spraying gun is arranged atthe top of the first mounting sleeve body, and a hot air gun is mounted at the top of the second mounting sleeve body; and a motor connected with the bottom of a circular rotary table is arranged atthe bottom of the circular supporting plate, and a third electric push rod is fixedly arranged at the top of the circular supporting plate. By means of the paint spraying device, irregular curved surface metal can be well sprayed, a paint film attached to the surface of the irregular curved surface metal can be rapidly dried, and the paint spraying efficiency of the irregular curved surface metalis improved.

Description

technical field [0001] The invention relates to the technical field of painting equipment, in particular to a painting device for metal with irregular curved surfaces. Background technique [0002] Spray paint is a coating method that is dispersed into uniform and fine droplets by means of a spray gun or a disc atomizer by means of pressure or centrifugal force and applied to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derived methods of the above basic spraying forms, such as large flow and low pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc. [0003] At present, there are four main types: arc spray painting, flame spray painting, plasma spray painting and explosive spray painting. Using paint spraying technology, coatings with wear-resistant, corrosion-resistant, heat-insulating, conductive, insulating, sealing, lubricating and other special...

AI Technical Summary

Problems solved by technology

Although the existing paint spraying device can carry out spraying operation to relatively regular metal materials, it itself cannot carry out good spraying work to irregular curved surface metals, especially for the metal surface with the central axis, which has a deep and central axis. For the flush plane of the plane, it is impossible to spray the nozzles in the vertical plane evenly. In addition, because the metal body to be sprayed is vertically connected, if the spraying method in the horizontal plane is used, the spraying on the deeper flush concave surface can be achieved. , but the large range of horizontal spraying will easily cause the paint liquid to leak to the outside. In addition, it cannot quickly dry the paint film attached to the irregular curved metal surface after spraying, making the painting efficiency relatively low

In addition, in the prior art, most of the metals with irregular curved surfaces are fixed by multiple clamping devices. However, the painting operation at the clamping position cannot be carried out normally due to the obstruction of the clamping structure, resulting in only partial area spraying.
