AI Technical Summary
In existing technologies, direct reciprocating spraying results in uneven coating distribution, and changes in spray gun pressure damage the coating before it dries, causing problems such as coating peeling and wrinkling. Furthermore, traditional clamping methods cannot cover the spraying blind spots of complex castings.
The mechanically linked spraying device achieves continuous single-pass spraying through the cooperation of the insert plate and the baffle. Combined with the rotation of the clamping plate driven by the hydraulic cylinder, it realizes multi-directional spraying of the casting, ensuring that the paint covers the casting layer by layer in one direction and provides sufficient drying time during the spraying process.
It achieves a smooth, dense coating with excellent anti-peeling and anti-wrinkle properties, avoids paint waste, covers the blind spots of traditional clamping methods, and improves the integrity and protective performance of the coating.
