Circular hollow pipe outer side wall paint spraying equipment and working method thereof

Abstract

The invention discloses circular hollow pipe outer side wall paint spraying equipment, and relates to the technical field of pipe paint spraying equipment. The circular hollow pipe outer side wall paint spraying equipment comprises a workbench and a rack, the rack is fixedly installed on the outer wall of the top of the workbench, clamps are arranged at the left end of an electric telescopic rod and an output shaft on the right side of a motor, a sliding rail is fixedly installed between the inner walls of the tops of the left side and the right side of the rack, the outer wall of the slidingrail is sleeved with a servo sliding table, a guide device is fixedly installed on the outer wall of the bottom of the servo sliding table, and a spray head is arranged on the outer wall of the bottomof the guide device. In the device, a trowelling block makes contact with the outer side wall of a circular hollow pipe, when the diameter of the circular hollow pipe is reduced, the trowelling blockcan move downwards under the action of a telescopic device, thus the guide device can automatically adjust the position of the spray head according to the diameter change of the circular hollow pipe,it is ensured that the distance between the spray head and the outer side wall of the circular hollow pipe cannot be changed, the situation that the circular hollow pipe is sprayed unevenly is avoided, and resources are saved.

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.

[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
