ABSTRACT:
An infrared dryer for printing presses has a main body (12), an ink shield (14), and a control box (16). The main body (12) has infrared lamps (30) positioned below a multiple-layer roof of sheet metal aluminum. The infrared lamps (30) are oriented toward the wet ink of printed matter at the delivery end of a printing press and the main body (12) is mounted within the printing press accordingly. The roof is comprised of an inside reflector (20) immediately above the infrared lamps (30) , a ligh box (22), and a direct space panel (b 24). These roof elements are separated by spacers (28) so that there are gaps between the elements. Fans (34) are employed to cool the main body (12) from the ehat generated by the infrared lamps (30). The fans (34) are mounted over a hole (36) in the direct spacer panel (24) and exhaust from the fans (34) goes through fan holes (38) and vent holes (48) in the other roof elements and through the gaps created by the spacers (28). Power is supplied to the infrared lamps (30) through bus bars (32) that are positioned in the gap created between the inside reflector (20) and light box (22) and is also cooled by the exhaust of the fans (34). The ink shield (14) is independent of the main body (12) and is positioned between the ink and water systems of the printing press and the main body (12) to act as a heat barrier to prevent the ink from thinning. A fan (106) is also mounted within the ink shield (14) to assist in cooling of the ink.
