Roller

Abstract

The invention provides a roller. The interior of a roller body is hollow and openings are formed in the two ends of the roller body; a micropore is formed on the roller body; a hairbrush sleeve sleeves on the peripheral surface of the roller body; two roller support bases are respectively arranged on the openings in the two ends of the roller body; mounting holes are formed on both of the two roller support bases; the quantity of pipe sleeves is two; the pipe sleeves are respectively penetrated into two mounting holes; a first conveying pipe is located in the roller body and is coaxially arranged with the roller body; the two ends of the first conveying pipe are respectively penetrated into the two pipe sleeves; a conveying hole is formed on the first conveying pipe; a helical blade sleeves on the first conveying pipe; the two ends of the helical blade are respectively connected with the two roller support bases; a second conveying pipe is hollow; one end of the second conveying pipe is communicated with the first conveying pipe; a connector is arranged at the other end of the second conveying pipe. The roller has the beneficial effects that the structure is reasonable, the roller is beneficial to the draining of the coating slurry from the conveying hole, the coating slurry leakage can be prevented, the coating slurry in the roller main body is uniform, the coating effect is better and the use effect is good and reliable.

Description

technical field [0001] The invention belongs to the technical field of paint painting tools, and relates to a roller. Background technique [0002] Roller brushes are often used when rolling large-area paint in daily architectural decoration projects. After connecting the extension rod, it can easily paint the high part of the wall or the ceiling. [0003] The existing roller brush needs to be constantly dipped in paint and then paint the wall during use. Such reciprocating operation is very time-consuming, and it is easy to splash the paint on the ground, causing pollution. [0004] For example, the Chinese patent with application number 201521076979.7 discloses a self-supply wall brushing roller, which relates to the field of construction tools. A cylindrical handle is fixed on the outside of the bearing of the automatic supply wall brushing roller, and a cylindrical handle is fixed on the inner ring of the bearing. Rotating shaft, one end of the rotating shaft is fixed w...

Problems solved by technology

[0005] But above-mentioned wall brushing roller, the effect when using is relatively poor, needs to continuously pour paint slurry water into the roller body from infusion tube, otherwise paint slurry water is difficult to come out from liquid outlet hole, reliable during use. The durability is not high, and the pressure of the roller body will be high. Once it is used for a long time, the paint slurry is easy to leak out, and the paint slurry on the roller body is not uniform enough, and the effect of brushing is poor.
