Background

At present, after the section bar is subjected to shot blasting and rust removal, the H-shaped steel needs to be sprayed with the anti-rust primer immediately, and the manual spray painting or the automatic spray painting mode driven by a three-phase asynchronous motor is usually adopted. However, the manual paint spraying mode has low efficiency, wastes paint and has low spraying quality.

The automatic paint spraying mode driven by the three-phase asynchronous motor is adopted, so that the paint spraying efficiency is greatly improved, but the following problems are caused due to the defects of the structure and the performance:

the three-phase asynchronous motor has large braking inertia, so that the buffer stroke is large, the moving stroke of the spray gun is difficult to control, and the moving stroke of the common spray gun is at least increased by 25 percent compared with the effective spray painting stroke.

The horizontal chain type transmission structure enables the moving speed of the spray gun to be unstable, so that the thickness of the paint film is uneven, the paint spraying quality is affected, and the paint waste is increased by more than 20%.

The mechanism structure formed by the three-phase asynchronous motor and the chain type transmission structure is heavy and has high noise in the operation process.

The detection means is few or even no, which results in missed spraying, re-spraying and empty spraying, and the paint waste is increased by more than 30%.

Meanwhile, a common plate paint spraying system in the market is only suitable for spraying plates and small-sized steel with the height of less than 300mm, but not suitable for spraying relatively large H-shaped steel.
