Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of house building construction, in particular to a wall rolling brush mechanism for house building construction. BACKGROUND

[0002] In the house building construction process, wall painting is a very key construction process. Among them, according to the differences of construction methods, materials, effects and application scenes, different construction methods are correspondingly adopted. In terms of construction methods, it is mainly divided into two categories of manual painting and mechanical painting, and manual painting covers a variety of specific processes such as roller, brush and spatula.

[0003] In order to improve the rolling brush efficiency, the existing rolling brush mechanism adopts the mode of adding feeding assembly outside the roller, and matching with external feeding equipment, so as to add paint to the bristles of the roller in an orderly manner. In this way, the operation of manually adding paint to the paint bucket frequently in the rolling brush process is avoided. However, this feeding mode will cause the paint to be concentrated and accumulated at the part where the bristles first contact with the paint, so that the paint cannot uniformly cover the surface of the bristles, and the situation of too much paint in some parts and too little paint in some parts occurs. In order to make the paint uniformly cover the wall, the rolling brush times have to be increased to make up for it. Although this structure design solves the problem of workload in the feeding process, it increases the workload in the rolling process to some extent. Therefore, the design structure has poor practicability in actual application. In view of this, the present application arises at the historic moment. SUMMARY

[0004] The purpose of the present application is to provide a wall rolling brush mechanism for house building construction, which can improve the uniformity of paint added to the bristle sleeve, thereby reducing the workload of manual rolling brush, improving the construction efficiency and construction quality, and making the design structure have better practicability.

[0005] The above technical purpose of the present application is realized by the following technical scheme: a wall rolling brush mechanism for house building construction, comprising a roller, a handle and a bristle sleeve arranged on the outer peripheral wall of the roller, wherein the inside of the roller is formed with a feeding cavity, a plurality of penetration holes communicating between the feeding cavity and the bristle sleeve are arranged on the roller, a feeding assembly is arranged in the feeding cavity, the feeding assembly is formed with a feeding area feeding towards the penetration hole side, a sealing assembly is formed between the feeding assembly and the feeding cavity, the feeding assembly is connected with a driving assembly driving the feeding assembly to rotate along the inner peripheral wall of the feeding cavity, the feeding assembly is connected with a feeding pipe penetrating out of the roller without interfering with the rotation of the roller, and the feeding pipe is connected with an external feeding equipment.

[0006] By adopting the above technical scheme, the external feeding device delivers the paint into the feeding assembly through the feeding pipeline, and then the paint is delivered to the side of the penetration hole through the feeding assembly, so that the paint can penetrate into the brush sleeve outside the roller through the penetration hole, and the brush sleeve can be coated with paint to perform the rolling operation. During the feeding process of the feeding assembly towards the side of the penetration hole, the driving assembly arranged in cooperation drives the feeding assembly to move along the rolling path of the roller, so that the paint can quickly and uniformly penetrate into the entire brush sleeve, to avoid the uneven distribution of the paint in the brush sleeve, reduce the labor intensity of the rolling operation for uniformly coating the paint on the wall, improve the construction efficiency and quality, and make the design structure have better practicability.
