Description

Technical Field

[0001] This utility model belongs to the field of roller brush technology, specifically relating to a roller brush for construction engineering. Background Technology

[0002] A roller brush is a painting tool consisting of a handle, a bracket, and a replaceable roller sleeve. It applies paint to the surface by rolling it over the roller sleeve, achieving large-area, high-efficiency paint application. It is mainly used in architectural decoration projects for walls, ceilings, and other areas. It is suitable for various liquid materials such as latex paint, rust-preventive paint, and interior and exterior wall paints. The length and material of the brush bristles affect the painting effect, and it needs to be used with a paint tray to control the amount of paint used. It features high construction efficiency and saves time and effort, but edges and corners require touch-ups.

[0003] For example, a roller brush for construction engineering with publication number CN223151579U addresses two problems existing in current roller brushes: 1. When using a roller brush to coat building walls, workers need to repeatedly dip the brush in the paint to complete the coating, which is inconvenient for workers and reduces work efficiency.

[0004] 2. When using a roller brush soaked in paint, the paint can easily drip onto the ground or onto the workers' arms, which not only pollutes the site but also results in some waste.

[0005] This technical solution, through the setting of a material conveying mechanism, can continuously deliver external paint to the discharge cylinder, and in conjunction with a roller brush, paint can be applied to the wall, achieving the goal of eliminating the need for multiple dips, making it easier for workers to operate and improving work efficiency. The solution, through the setting of protective plates, brushes, and triangular receiving boxes, can evenly scrape the paint on the roller brush surface and collect the scraped paint for reuse, achieving the goal of recycling. It also prevents paint from dripping down and causing stains on the floor, and reduces subsequent cleaning time.

[0006] However, in this technical solution, the paint spreads from the inside of the roller brush to the outside. During use, paint residue will remain inside the roller brush, and prolonged use will cause the roller brush to jam. The dripping paint is to be recycled, but the paint that has been in contact with the air will be contaminated. Direct reuse will contaminate the new paint, thus affecting the final spraying effect.

[0014] This utility model discloses a roller brush for construction projects. Compared with the prior art, the advantages of this roller brush are as follows: The roller brush uses a spraying structure to directly spray paint onto the wall surface, preventing excessive paint from adhering to the brush and thus avoiding paint waste to a certain extent. Simultaneously, a roller brush is installed at both the top and bottom of the spraying structure to evenly coat the paint on the wall surface. When paint falls off the wall, it falls directly onto the roller brush, ensuring a cleanliness of the work area to a certain extent. Attached Figure Description
