Steel tube UV-curing color-painting mechanism

Abstract

The invention discloses a steel tube UV-curing color-painting mechanism. A cylinder and a guide rail of a linear guide rail pair are horizontally arranged on a cantilever beam bracket. A piston rod end of the cylinder and a sliding block of the linear guide rail pair are respectively fixedly connected with a lifting cylinder support, the lifting cylinder support horizontally is driven to move long the linear guide rail through the retraction of a piston rod of the cylinder; the cylinder body of a lifting cylinder is fixedly connected with the support, a piston rod end of the lifting cylinder are fixedly connected with a rubber roll color-painting device, the rubber roll color-painting device is driven to move vertically through the retraction of the piston rod of the lifting rod; and a UV lamp shade is arranged on a steel tube. When the UV-curing color-painting mechanism works, ink (paint) is evenly printed on the steel tube after transferred through an anilox roller, a distributor roller and an offset printing roller to form a color ring. By adopting a principle of curing UV ink (paint) by UV, the color ring painted on the steel tube is instantly dried, thus the working efficiency and the color ring effect are greatly improved. Especially, the invention avoids the drop of corrosion resistant coating because color ring coating is not dried fully to influence the UV corrosion resistance.

Description

technical field [0001] The invention relates to a steel pipe ultraviolet curing coloring ring mechanism, in particular to a steel pipe ultraviolet curing coloring ring mechanism. Background technique [0002] In the current existing steel pipe color ring equipment, there are two ways of painting with a roller and spraying with a spray gun. The purpose of spraying the color ring is to distinguish the steel grade of the steel pipe. If the paint is applied directly with a roller, the thicker the coating, the phenomenon of dripping will appear, the coating will be uneven, and it will not be easy to dry; if the paint is sprayed with a spray gun, the edge of the color circle will be unclear, and the air pollution will be serious. The disadvantage of spraying the color circle with ordinary paint is that the paint dries slowly, and when the steel pipe is transported, the paint is printed or dripped on other equipment to damage the environment, and the color circle of the steel pipe ...

AI Technical Summary

Problems solved by technology

The color ring paint contains volatile agents, which are dried by the volatilization of the volatile agent. Before spraying the UV anti-corrosion paint (the color ring paint is covered by the UV paint), if the color ring paint is not completely dry, after the UV anti-corrosion paint is cured, the color ring paint The volatile agent in the UV paint cannot be volatilized through the UV paint, so the paint on the color ring part is easy to peel and fall off, which will affect the anti-corrosion effect

If the color ring paint is completely dry before spraying anti-corrosion paint, it will greatly affect the production efficiency
