APPARATUS FOR SUPPLYING RAW MATERIAL CAPABLE OF IMPROVING PROCESS EFFICIENCY BY AUTOMATICALLY CONTROL WATER LEVEL OF RAW MATERIAL

摘要

PURPOSE: An apparatus for supplying raw material is provided to minimize thickness deviation of films due to apply constant amount of film materials because level of the film materials is maintained constantly in the raw material storage unit.;CONSTITUTION: An apparatus for supplying raw material comprises a raw material storage unit(110), a carrier film(120), a casting roller(130), a level regulating plate(140), and a plate driving unit(150). The film materials are inserted into the raw material storage unit. The carrier film is horizontally transferred to one side of the raw material storage unit. The casting roller rotates along a transferring direction of the carrier film and it applies the liquefied film materials inserted into the raw material storage unit onto the carrier film. The level regulating plate vertically drives in the raw material storage unit and controls the level of the liquefied film materials. The plate driving unit let the level regulating plate move upward and downward.;COPYRIGHT KIPO 2012
