PRESSURE FEED TYPE ROLLER COATING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a pressure feed type roller coating machine usable widely from photocatalytic coating materials and other low viscosity coating materials to general coating materials containing pigments. SOLUTION: In this pressure feed type roller coating machine A, a roller shaft 4 has a plurality of small holes 41 axially provided in a row and a coating roller 5 is a composite cylindrical rotary body and comprises outer cylindrical elements 52 (520, 521 and 522) being coating action members and one or plurality of inner cylindrical elements 51 (511) being coating solution dispersing members. The coating roller 5 is sealed at both ends thereof in the state mounted on the roller shaft 4 and has a large number of coating solution flow routes 510 comprising fine gaps or reticulated fine pipes at least continuted in the cross-sectional radial direction of the inner cylindrical elements 51 (511). Further, a flow rate-finely adjusting valve is provided to a coating solution flow channel 6. The coating solution is introduced into the coating roller 5 under pressure and particles in the coating solution are forcibly dispersed in a flow process by coating solution flow routes 510 of the coating roller 5 before the coating solution is allowed to uniformly penetrate into the coating action members.
