Agitated wet process machine

Abstract

An agitated wet process machine comprises a delivery system and many jets. The delivery system comprises a delivery belt and many rollers, wherein the rollers on the upper side or the lower side of the delivery belt are used to deliver workpieces. Many blades are added on each of the rollers to agitate a chemical solution. The jets above and below the delivery belt are used to spray or supply the chemical solution to the workpieces.
