Description

Technical Field

[0001] The present invention relates to the technical field of spraying devices, and particularly to a spraying device for building decoration with adjustable spraying range. Background Art

[0002] During the process of building decoration, it is necessary to spray paint on walls or decorative panels so that the walls or decorative panels can achieve the specified aesthetic effect. During the spraying process, a spraying device is required to spray the paint evenly.

[0003] Considering that during the spraying process, the shapes and sizes of the spraying plates or spraying walls are different, spraying equipment with fixed nozzle shapes and spraying ranges will cause low spraying efficiency or repeated spraying. Therefore, some spraying equipment with special structures and functions can be applied.

[0004] Generally, the spraying range shape and size of the nozzles of traditional nozzle equipment are fixed. When spraying some relatively wide walls, the efficiency will be low. If the spraying range of the nozzle is increased, when spraying some relatively narrow walls, repeated spraying will occur at the edges, which will affect the thickness of the colored paint. Moreover, the spraying shape is fixed, so when spraying some circular decorative panels, repeated spraying will occur at the edges. During the spraying process, the connection between the top of the wall and the vertical wall needs to be protected separately to avoid mutual influence during the spraying process, which is very inconvenient. Therefore, it is necessary to design a spraying device for building decoration with adjustable spraying range. Summary of the Invention
