Ink drier for sheet-fed rotary press

Abstract

Abstract PURPOSE:To reduce the amount of spray powder or dust attached to a heat source or reflecting plate and to improve the drying efficiency and working properties, by providing ribs on the outer surfaces of, at least, a half of the reflecting plates, thereby forming an air circulating slit between the adjacent reflecting plates. CONSTITUTION:The air flow raised by a ventirating fan 50 is blown from a vent 51 into a hermetically-sealed space defined between a rear cover 33 and reflecting plates 38 and is further blown toward infrared lamps 36 through a slit formed between the adjacent reflecting plates 38 by means of spacer ribs 38a, thus forming convection currents. Accordingly, spray powder or dust is blown away by this strong air flow and is consequently prevented from adhering to the lamps 36 and the reflecting plates 38. Further, the inside of a casing 31 is cooled by the air. When it is necessary to clean the infrared lamps 36 or the reflecting plates 38 because they have become dirty through the use over a long period of time, or when the infrared lamps 36 are to be replaced with new ones, bolts 34 are untightened, and the rear cover 33 is removed from the machine, whereby the reflecting plates 38 are also taken out of the machine, together with the rear cover 33. Thus, cleaning can be easily effected.
