Description

Technical field [0001] The invention belongs to the field of printing equipment, and relates to an optimized design method for an air inlet duct system of a gravure printing machine oven. Background technique [0002] At present, most of the drying ovens of gravure printing presses are located between the printing units, and the printing ink on the web substrate or substrate is dried by hot air blown from rows of air nozzles. Among them, the air inlet duct system of the gravure printing machine oven is composed of a fan, a heater, an air inlet pipe, a return air pipe, and a tube cavity, and is responsible for the work of delivering hot air to the oven. After being heated by the heater, the fresh air and the re-used hot air are sent to the oven through various forms of pipes. Existing gravure printing machine drying oven air inlet duct system design generally adopts empirical design method without optimization design, but the designed oven is prone to eddy currents, resulting in ...
