Description

Technical Field

[0001] The utility model relates to a spraying technology, in particular to a steel structure spraying device. Background Art

[0002] Spraying is a coating method that uses a spray gun or a disc atomizer to disperse into uniform and fine droplets with the help of pressure or centrifugal force and apply them to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivative methods of the above basic spraying forms, such as high-flow low-pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc. Spraying operations have high production efficiency and are suitable for manual operations and industrial automation production. Since steel structures require large-area spraying, the nozzles need to be used for a long time during spraying, and the spraying area is large. Long-term use will cause paint dirt to form around the nozzles, thereby affecting the normal spraying of the nozzles, and they need to be disassembled and cleaned in time. A nozzle installation structure that can be disassembled in a timely and convenient manner is required. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figures 1 to 5As shown, the steel structure spraying device of the utility model comprises a conveyor belt 1, a fixed component 2 and a spray head 3, wherein the fixed component 2 is arranged above the conveyor belt 1, and the spray head 3 is installed on the fixed component 2. The conveyor belt 1 is used to convey the steel structure workpiece to be sprayed, and when the steel structure workpiece is conveyed to the lower end of the fixed component 2, the spray head 3 arranged on the fixed component 2 is used to spray the steel structure workpiece at the lower end.

[0023] Both ends of the conveyor belt 1 are provided with symmetrically arranged mounting columns 4, and a mounting plate 5 is symmetrically arranged between the mounting columns 4. A mounting hole 6 is provided on the mounting plate 5, and a plurality of bayonet holes 7 are provided in the mounting hole 6, so that the hanging member 8 can be installed in the bayonet holes 7 at different angles, so that the hanging member 8 can fix the nozzle 3 at different angles to adapt to the extension direction of the spray pipe.

[0024] The fixing assembly 2 is provided with a hanging member 8 and a retaining ring 9. The fixing assembly 2 realizes the installation of the hanging member 8 by the cooperation between the hanging member 8 and the mounting hole 6. The hanging member 8 is installed on the retaining ring 9, and the upper end of the hanging member 8 is arranged in the mounting hole 6. A through hole 10 is formed in the middle of the retaining ring 9. The hanging member 8 is composed of an arc segment 12 and a symmetrically arranged hanging segment 11.
