AI Technical Summary
Existing coating equipment for composite plastic woven bags cannot effectively remove debris from the surface of the woven bag substrate before spraying, resulting in poor spraying effect.
A coating device was designed, comprising a fan, a housing, and an air distribution plate. The fan blows air through a duct and guides it to the air distribution plate. The gas is blown at an angle onto the surface of the woven bag to clean up debris. The gas is preheated by heating wires to heat the substrate. Combined with auxiliary cooling components, the coating is cooled down quickly to ensure good adhesion.
It effectively removes debris from the surface of woven bag substrate, improves the spraying effect and adhesion of coatings, and saves energy consumption.
