Wall decoration coating roller capable of controlling uniform discharging

Abstract

The invention relates to the technical field of wall decoration, and discloses a wall decoration coating roller capable of controlling uniform discharging. The wall decoration coating roller comprises a rotating roller body and a rotating mounting shaft, the outer side of the rotating roller body is fixedly connected with a brushing layer, the rotating roller body is internally provided with a coating material storage cavity, the outer side of the coating material storage cavity is fixedly connected with a discharging pipeline, a liquid outlet switch valve is fixedly connected into the discharging pipeline, and a mounting groove is formed in the rotating roller body. According to the wall decoration coating roller capable of controlling uniform discharging, the brushing layer makes contact with the wall surface, the rotating roller body rolls along the wall surface, in the rolling process, the wall surface presses the brushing layer so as to press a corresponding induction pressing plate, a dielectric plate is inserted between a positive plate and a negative plate, the dielectric plate controls circuit voltage passing through the negative plate, after the working voltage of a piezoresistor is reached, the circuit is connected to open the liquid outlet switch valve for discharging, and the coating material is output into the brushing layer from the coating material storage cavity through the discharging pipeline for roller coating.

Description

technical field [0001] The invention relates to the technical field of wall surface decoration, in particular to a paint roller for wall surface decoration that can control uniform discharge. Background technique [0002] Roller coating uses a roller as the carrier of the paint. The paint forms a wet film of a certain thickness on the surface of the roller, and then the paint is applied to the surface of the object by contacting the object to be coated during the rotation of the roller. Roller coating is suitable for flat coated objects. It is widely used in the coating of metal plates, plywood, cloth and paper, especially for metal coil coating. [0003] The roller used for roller coating is a hollow cylinder with a small diameter, and the surface layer is usually made of a strong absorbent material such as synthetic fiber or wool. It can be roughly divided into three types: brush roller, cloth roller and pattern roller. It is most suitable for large-area painting of water...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a paint roller for wall surface decoration that can control uniform discharge, which has the advantages of good brushing effect and automatic replenishment of paint, and solves the problem that the existing roller structure is relatively simple, Generally, the paint is replenished by dipping. The paint is unevenly distributed on the surface of the roller, which will easily lead to uneven thickness of the brushing layer and affect the decorative effect.
