Coating spraying device and method for steel bar production with anti-collision mechanism

Abstract

The invention discloses a steel bar production coating spraying device with an anti-collision mechanism in the technical field of steel bar production. There are openings on the top, the derusting chamber is provided with a derusting mechanism, the left side of the partition plate is provided with a cleaning mechanism, the spraying chamber is provided with an anti-collision spraying device, and the drying There is a drying mechanism in the cavity. The rust removal mechanism in the rust removal cavity can remove the rust on the steel bar through the rust removal solution before the steel bar is sprayed, and a cleaning mechanism is also provided. The rotation of the ring piece makes the contact block The outer wall of the steel bar is cleaned by the bristles to ensure the spraying quality of the steel bar by the subsequent anti-collision spraying device. On the one hand, the adhesion of the subsequent coating is improved, so that the coating will not fall off and there is no need to transport the steel bar to the derusting equipment, which greatly improves Work efficiency is reduced at the same time.

Description

technical field [0001] The invention relates to the technical field of steel bar production, in particular to a coating spraying device and method for steel bar production with an anti-collision mechanism. Background technique [0002] Reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including plain round bars, ribbed bars, twisted bars. [0003] Steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures. In order to avoid a large amount of corrosion on the surface of steel bars during long-term use, most of the steel bars are sprayed with paint. [0004] But the existing steel bar production coating spraying device has the following defects in use: 1, the steel bar tends to get rusty due to air humidity in the process of storage, and the direct spraying paint is not carried out t...

Problems solved by technology

[0004] But the existing steel bar production coating spraying device has the following defects in use: 1, the steel bar tends to get rusty due to air humidity in the process of storage, and the direct spraying paint is not carried out to the steel bar for derusting, which not only affects the spraying process. The anti-rust quality of the formed coating, and the coating adhesion is poor, easy to fall off, reducing the protection of the steel bar, and the rust removal of the steel bar needs to transport the steel bar to the derusting equipment for derusting and then spraying. A large amount of manpower is required, which reduces work efficiency; 2. The existing spraying device is not adjustable, and at the same time, due to the unstable transportation of the steel bar, the outer wall of the steel bar is easy to collide with the spraying device, which greatly reduces the spraying quality and reduces the spraying device. At the same time, the quality of spraying on steel bars is poor, and it cannot be sprayed comprehensively. Therefore, we propose a coating spraying device and method for steel bar production with an anti-collision mechanism
