Intelligent airless spray gun for spraying semi-enclosed space

Abstract

The invention discloses an intelligent airless spray gun for spraying a semi-enclosed space. The intelligent airless spray gun comprises a spraying part; the spraying part comprises a gun pipe, a connecting pipe, a cylindrical shell and a hollow rotating shaft; a cylindrical connector is arranged at one end of the gun pipe integrally; one end of the connecting pipe is spirally connected with the interior of the cylindrical connector; the other end of the connecting pipe is spirally connected into the interior of one end of the cylindrical shell; a fixed sleeve is welded at the end part of theother end of the cylindrical shell in a communicating manner; the hollow rotating shaft is fixedly mounted in the fixed sleeve by means of a rolling bearing; one end of the hollow rotating shaft extends out of the fixed sleeve; and the other end of the hollow rotating shaft extends into the cylindrical shell. Semi-enclosed spaces can be effectively sprayed, the spraying quality is high, the spraying efficiency is high, the intelligent airless spray gun is convenient to dredge and clean when being blocked, the dismounting and the mounting are convenient, the applicability is high, and the surface of the intelligent airless spray gun is not likely to be tainted with a large amount of oil paint in the spraying operation.

Description

technical field [0001] The invention relates to the technical field of spray guns, more specifically, it relates to an intelligent airless spray gun for spraying in a semi-enclosed space. Background technique [0002] Existing ordinary high-pressure airless spray guns are used for steel structure coating and spraying. High-pressure airless spraying, also known as airless spraying, refers to the use of high-pressure plunger pumps to directly pressurize the paint to form high-pressure paint. A spraying method that sprays out the muzzle to form an atomized airflow that acts on the surface of the object (wall or wood surface). Compared with air spraying, the paint surface is uniform without graininess. Due to the isolation from the air, the paint is dry and clean. Airless spraying can be used for the application of high-viscosity paint, and the edges are clear, and it can even be used for some spraying projects with boundary requirements. According to the type of machinery, i...

Problems solved by technology

[0003] The existing high-pressure airless spray guns cannot effectively spray some semi-closed spaces (such as the inside of the telescopic boom, square cross-section or other shaped tubular objects), the spraying quality is poor, the spraying efficiency is low, and it is difficult to unblock when blocked It is inconvenient to clean, disassemble and assemble, and the applicability is not good. During the spraying work, the surface is easily contaminated with a large amount of paint. Therefore, an intelligent airless spray gun for spraying in a semi-enclosed space is proposed.
