Description

A new type of coating machine

technical field

The invention relates to the technical field of coating, in particular to a novel coating machine.

For the purposes of anti-corrosion, insulation, and decoration, liquid or powder and other forms to coat a thin layer of plastic on the surface of fabrics, paper, metal foil or boards. At present, when the existing coating machines accurately coat various liquid coatings on the surface of PVA, PET and other film materials, they generally use anilox coating rollers for coating. Accurate, but the amount of coating is difficult to adjust.

When using anilox roller coating, the amount of coating is mainly related to the depth of the concave hole of the anilox roller and the precision of the glue type. The deeper the concave hole depth of the anilox roller, the more the amount of glue transferred from the concave hole to the substrate; on the contrary, the shallower the concave hole depth of the anilox roller, the less the amount transferred to the substrate. It also has a lot to do with viscosity. Too much or too little glue viscosity is not conducive to the normal transfer of glue.
