In the process, the piston rods at the two ends of the bidirectional cylinder 52 continuously stretch out and draw back to drive the two racks 51 to synchronously move towards the directions approaching or separating from each other, so that the rotation directions of the two mounting rings 2 are just opposite, the directions of the paint speeds of the spray heads 31 on the two mounting rings 2 sprayed into the steel member are crossed, namely, the directions of the speeds along the tangential directions of the mounting rings 2 are opposite, the paint spraying dead angles in the steel member are reduced, the uniformity of paint spraying on the inner surface and the outer surface of the steel member is ensured, and the paint spraying quality is improved. In the process of rotating the mounting ring 2, the spray head 31 rotates relative to the steel member, and the spraying angle of the paint is changed differently, so that the paint is easier to spray into the I-steel or the channel steel, and the quality of the paint is improved.
Because the length of steel members such as the I-steel is generally longer, the weight is larger, if the uniform paint spraying is realized by rotating the I-steel, a rotating mechanism capable of rotating the whole I-steel and a fixing mechanism for fixing the position of the I-steel are required to be arranged, the structure is complex, the energy consumption is serious, and therefore, the mode is not applicable.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
