Description

Roller brush capable of automatically supplying paint

Technical Field

The invention relates to the field of decoration tools, in particular to a roller brush capable of automatically supplying paint.

Background

The roller brush is also called a roller, is divided into three types, namely long hair, medium hair and short hair, and is a tool for rolling and coating large-area paint. The classification of the roller brush is mainly divided according to the different applications, and generally, the main applications of the roller brush include brushing, napping and the like, so the roller brush can be divided into various types such as a paint roller brush, a napping roller brush, a floor paint roller brush, a flat-coating roller brush and the like, is mainly applied to relatively large-area brushing of architectural decoration engineering, and can be used for brushing and rolling various mixed paints. When the roller brush is used, the roller brush only needs to keep straight brushing, if the roller brush is used for uniformly brushing, the roller is preferably put into a coating cylinder and the like, is taken out after being completely absorbed, is rolled on an inclined plane, and is brushed again after excessive paint is extruded.

However, in actual practice, there are the following problems:

1. the coating needs to be repeatedly dipped manually, so that more time is wasted, and the working efficiency is reduced;

2. the dipped roller brush needs to be placed for a period of time, and the wall brushing operation can be carried out when the paint on the roller brush does not drip any more, so that a large amount of time is wasted;

3. in the process of brushing the wall, because the brush hair adsorbs a large amount of paint, the roller brush is easy to splash in rolling and fall on the ground or clothes of people, and the cleaning is troublesome;

4. in the actual operation process, the coating drips to cause waste and increase the capital investment.

In order to avoid the above problems, it is necessary to design a roller brush capable of solving the above problems.
