Circular tube polishing and painting device

Abstract

The invention aims to provide a circular tube polishing and painting device capable of improving the polishing and painting efficiency and lowering the labor burden of workers. The circular tube polishing and painting device is composed of a travelling frame, a polishing mechanism, a paint spraying mechanism and a painting mechanism, wherein the polishing mechanism, the paint spraying mechanism and the painting mechanism are arranged on the travelling frame; the polishing mechanism is composed of a rotating frame of a tubular structure and a driving mechanism for driving the rotating frame torotate, and grindstones are mounted on the inner wall of the rotating frame through elastic mechanisms; the paint spraying mechanism comprises three or more clasping arms, one ends of the clasping arms are connected with the travelling frame through elastic mechanisms so that the free ends of the clasping arms tend to be in a clasping state, and the free ends of the clasping arms are provided withidler wheels; the clasping arms are provided with paint tubes, the ends of the paint tubes are provided with paint spraying holes, the paint tubes are connected with a paint storage cylinder on the travelling frame, and the paint storage cylinder is provided with a pressurizing device; and the painting mechanism is composed of a rotating frame of a tubular structure and a driving mechanism for driving the rotating frame to rotate, and brushes are mounted on the inner wall of the rotating frame through elastic mechanisms.

Description

technical field [0001] The invention belongs to the technical field of mechanical surface processing, and in particular relates to a circular tube polishing and painting device. Background technique [0002] In order to prevent rust, the surface of the metal round tube generally needs to be polished and painted. The traditional polishing method is to manually polish the round tube with a grinding wheel. The traditional painting method is to manually brush around the round tube with a brush. The above operations are very inconvenient. It is convenient, and it is difficult to ensure that all positions of the round tube are polished and painted evenly. For longer circular pipes, the efficiency of the above-mentioned manual polishing and painting methods is low, and the labor intensity of workers is also greatly increased. Therefore, be badly in need of a kind of circular tube polishing and painting device that can improve polishing and painting efficiency, reduce worker's labo...
