A kind of equipment for spraying paint on the outer wall of a circular hollow pipe and its working method

Abstract

The invention discloses a painting equipment for the outer wall of a circular hollow pipe in the technical field of pipe painting equipment. It includes a workbench and a frame. The side output shafts are all provided with fixtures, slide rails are fixedly installed between the top inner walls on the left and right sides of the frame, the outer walls of the slide rails are sleeved with servo slides, and the outer walls of the bottom of the servo slides are fixed with guide devices. And the outer wall of the bottom of the guide device is provided with a nozzle, and the device contacts the outer wall of the circular hollow tube through a smoothing block. When the diameter of the circular hollow tube decreases, the smoothing block will move downward under the action of the telescopic device, so that the guide The device can automatically adjust the position of the nozzle according to the diameter change of the circular hollow tube to ensure that the distance between the nozzle and the outer wall of the circular hollow tube will not change, avoiding uneven spraying of the circular hollow tube and saving resources .

Description

technical field [0001] The invention relates to the technical field of pipe painting equipment, in particular to a round hollow pipe outer wall painting equipment and a working method thereof. Background technique [0002] During the painting process of the circular hollow pipe, the fixture is inserted into the inner cavity of the circular hollow pipe to fix it, and the paint is sprayed onto the circular hollow pipe through the nozzle by rotating it with the fixed circular hollow pipe. On the outer wall, however, when processing a pipe welded together by two circular hollow pipes with different diameters, when the nozzle moves to the top of the circular hollow pipe with a smaller diameter, the distance between the nozzle and the pipe will increase, resulting in When the paint sprayed from the nozzle reaches the outer wall of the circular hollow tube, the coverage of the paint increases. Because the diameter of the circular hollow tube becomes smaller, it is easy to cause par...

[0002] During the painting process of the circular hollow pipe, the fixture is inserted into the inner cavity of the circular hollow pipe to fix it, and the paint is sprayed onto the circular hollow pipe through the nozzle by rotating it with the fixed circular hollow pipe. On the outer wall, however, when processing a pipe welded together by two circular hollow pipes with different diameters, when the nozzle moves to the top of the circular hollow pipe with a smaller diameter, the distance between the nozzle and the pipe will increase, resulting in When the paint sprayed from the nozzle reaches the outer wall of the circular hollow tube, the coverage of the paint increases. Because the diameter of the circular hollow tube becomes smaller, it is easy to cause part of the paint to not be sprayed on the outer wall of the circular hollow tube, resulting in waste, and The increase of paint spraying range leads to the thinning of the paint sprayed on the outer wall of the circular hollow pipe. Because the pipe rotates at the same speed and the nozzle moves at a fixed speed, the paint thickness in the area with a large diameter of the pipe is greater than that in the area with a small diameter. area, resulting in poor quality of circular hollow pipe painting, for this reason, we propose a circular hollow pipe outer wall painting equipment and its working method
