Pneumatic material feeding roller brush

Abstract

The invention belongs to a roll painting device, and in particular relates to a pneumatic loading roller brush. The aim of the invention is to provide a highly-efficient roll painting device integrating the functions of automatic loading and roll painting. The pneumatic loading roller brush comprises a bearing frame, a cylindrical roller, a roller enwrapping layer and a handle, wherein round through holes are distributed all over the cylindrical roller, a common bearing is embedded on the left end of the cylindrical roller, a sealed bearing is embedded on the right end of the cylindrical roller, inner rings of the common bearing and the sealed bearing are in small interference connection with a hollow shaft which is fixedly connected with the bearing frame, the outer port of the right end of the hollow shaft is sleeved with a material-injecting hose one end of which is sleeved on a discharge port of a pneumatic material storage bucket, and the material-injecting hose is provided with a flow regulating valve for controlling the flow rate of the paint. The roll painting device has the advantage of integrating the functions of automatic loading and roll painting, not only can improve the working efficiency, relieve the labor intensity, save paint and reduce environmental pollution, but also can keep the even material-discharging quantity by keeping the roller brush constant due to the stability of the liquid pressure in the cylindrical roller, thereby improving the roll painting quality.

Description

technical field

[0001] The invention belongs to a rolling coating device, in particular to a rolling coating operation tool for automatically pumping liquid paint through air pressure, which is used for the rolling coating operation on the inner and outer walls and ceilings of buildings. Background technique

[0002] The existing roller coating operation method is carried out by dipping and absorbing the paint into the artificial wool fabric on the surface of the roller brush. The workers continue to repeat the process of dipping the material-rolling coating, which is labor-intensive and inefficient. The woolen fabric is soaked with paint, and it is easy to drip the paint during the process of moving the roller brush from the bucket to the working surface, which wastes the paint and pollutes the environment. Continuous consumption during the coating process will inevitably lead to uneven coating thickness on the working surface, and it is difficult to guarantee the quality o...
