AI Technical Summary
During the spraying process, if the pressure of the spray head is insufficient, the viscosity of the paint is too high or too low, or there are bubbles in the paint, the paint cannot be evenly sprayed onto the substrate, resulting in the problem of uneven spraying.
A spray roller coating equipment is designed, including coating rollers and driving rollers parallel to each other. The coating roller is equipped with a cover plate and a liquid-absorbing brush. The paint spray head is arranged on the top of the cover plate. The cover plate is driven to move back and forth through the turntable. The liquid-absorbing brush reciprocates on the surface of the coating roller to apply the paint evenly to ensure uniform adhesion.
When the spray head is unevenly sprayed, the automatic uniform coating of the liquid-absorbing brush ensures uniform coverage and adhesion of the paint, solves the problem of uneven spraying, and saves power source.
