Coating brush facilitating control over coating thickness

Abstract

The invention relates to the field of coating devices, in particular to a coating brush facilitating control over the coating thickness. The coating brush comprises a fixing rod, an extension structure, a coating structure, a cleaning structure, an injection structure, a fixing structure, a pressure relief structure and a regulating structure; the feeding structure is driven to work by the coatingstructure synchronously while the coating structure works for coating; through cooperative application of the coating structure and the injection structure, the coating injection work can be made forthe coating structure automatically while the coating is performed, and manual repeated dipping of coatings or additional coating work is not required; not only can manpower be saved, but also the coating efficiency can be improved greatly, namely that when the coating structure does not work, the coatings are not injected into the coating structure; thus, the function of avoiding coating waste can be achieved, and through arrangement of the cleaning structure, particle impurities sticking to the coating structure can be cleaned in time; and the coating quality is ensured.

Description

technical field [0001] The invention relates to the field of paint painting devices, in particular to a paint brush which is convenient for controlling the coating thickness of paint. Background technique [0002] Paint (paint), what we usually call paint is just one of them. Refers to a type of liquid or solid material that can form a thin film coated on the surface of an object under certain conditions for protection, decoration or other special functions (insulation, rust prevention, mildew resistance, heat resistance, etc.). Because most of the early paints used vegetable oil as the main raw material, they are also called paints. Now synthetic resin has replaced vegetable oil, so it is called paint. Coatings are not liquid, and powder coatings are a large category of coatings. Coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the classification of modern chemical products, coating...

Problems solved by technology

[0003] Because paint brushes need frequent dipping operations when performing wall painting work, when painting high-altitude building walls, it is necessary to increase the labor intensity of operators, and due to frequent dipping work, there may be Causing the accidental fall of the operator will pose a hidden danger to the personal safety of the operator
