Device for uniform paint spraying on surface of metal pipeline

Abstract

The invention discloses a device for uniform paint spraying on the surface of a metal pipeline. A bottom plate is included. A left support and a right support are arranged on the two sides of the bottom plate correspondingly. An L-shaped plate is arranged on the top of the left support and provided with a paint box. A paint pump is arranged at the bottom of the inner side of the paint box and connected with a hose. One side of the right support is provided with a first bearing block. The first bearing block is rotationally connected with a rotation shaft. The rotation shaft is in cup joint with a big gear. The end portion of the rotation shaft is fixedly connected with a first clamping mechanism. A top plate is connected between the L-shaped plate and the top of the right support. A first support rod and a second support rod are connected to the two ends of the bottom of the top plate correspondingly. A motor is arranged at the bottom of the first support rod. An output shaft of the motor is provided with a first gear. The end portion of the second support rod is rotationally connected with a second gear. The second gear and the first gear are sleeved with a chain, and a guiding barrel is arranged below the chain. The device is simple in operation, and the effects that all-direction paint spraying is achieved, the paint spraying efficiency is high, paint spraying is uniform, applicability is wide, and paint waste is avoided are achieved.

Description

technical field [0001] The invention relates to the technical field of metal painting, in particular to a device for uniform painting on the surface of metal pipes. Background technique [0002] Painting metal surfaces is a method of protecting metal from oxidative corrosion. The corrosion phenomenon that occurs around us refers to the damage, performance degradation or deterioration of the state of various materials under the action of the environment. Spraying paint on the metal surface is a very important means of maintaining metal corrosion resistance. A good paint coating protection layer remains continuous and intact, well bonded, and can act as a barrier to inhibit the intrusion of corrosive media. Since corrosion is an irreversible spontaneous process, it is difficult to protect the metal from corrosion even with a high-quality paint coating, especially when the paint coating on the metal surface is poorly bonded, damaged, or has pinholes, bubbling, If there are d...

AI Technical Summary

Problems solved by technology

Since corrosion is an irreversible spontaneous process, it is difficult to protect the metal from corrosion even with a high-quality paint coating, especially when the paint coating on the metal surface is poorly bonded, damaged, or has pinholes, bubbling, Cracks, peeling and other defects, the protective effect of the spray paint coating will be greatly reduced, and even cause the consequences of increased metal corrosion

[0003] Most of the existing metal pipes are painted by manual spraying and device spraying. There are common problems such as inability to spray paint in all directions, low painting efficiency, uneven painting, poor applicability, and paint waste.
