Spraying device for processing inner wall of cylindrical container

Abstract

The invention relates to a spraying device for processing the inner wall of a cylindrical container. The device comprises a base, a top plate, a controller, a placing mechanism, a spraying mechanism,two vertical rods and two sealing mechanisms, wherein the placing mechanism comprises a platform, a driving assembly, a plurality of positioning assemblies and a plurality of supporting legs, the positioning assemblies comprise strip-shaped openings, transmission bevel gears, screw rods, translation blocks, movable plates, cross rods and clamping plates, the sealing mechanisms comprise side plates, lifting assemblies, telescopic assemblies, air cylinders, sleeve rings and sealing plates. According to the spraying device for processing the inner wall of the cylindrical container, the position of the container is adjusted conveniently through the placing mechanism, so that a spray pipe in the spraying mechanism and the axis of the container are positioned on the same straight line, uniform spraying is facilitated, and the spraying quality is ensured, moreover, a bottle opening of the container can be sealed by the sealing mechanisms in a spraying process, so that the situation that paintis diffused to the outside of the container to influence the respiratory health of a user is prevented, the spraying safety is guaranteed, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the field of spraying equipment, in particular to a spraying device for processing the inner wall of a cylindrical container. Background technique [0002] Spraying is a coating method in which spray guns or butterfly atomizers are dispersed into uniform and fine droplets 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, and electrostatic spraying. And various derivative methods of the above basic spraying forms, such as large flow and low pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc., the production efficiency of spraying operation is high, suitable for manual operation and industrial automation production, and the application range is wide , mainly in hardware, plastics, furniture, military industry, ships and other fields, is the most common coating method used today.

AI Technical Summary

Problems solved by technology

However, the existing spraying device usually sprays in an open container when spraying, and the sprayed paint easily overflows the outside of the container and diffuses into the surrounding air, affecting the respiratory health of the operator. When spraying, it usually relies on spraying to rotate inside the container to spray the surrounding inner wall, but the existing equipment cannot accurately position the nozzle on the central axis of the cylindrical container, resulting in a gap between the nozzle and the inner wall of the container during the rotation of the nozzle. There is a change in the distance between them. For the inner wall with a closer distance, the paint coverage is thicker, which wastes spraying materials. For the inner wall with a longer distance, the paint coverage is thinner, and the corrosion resistance is poor, which reduces the quality of spraying, which in turn leads to the existing spraying. Reduced utility of the device
