Analysis and Optimization of Hot Air Drying Device of a Gravure Printing Machine Based on Fluid Analysis
in this paper, analysis of the fluid dynamics was carried out on hot air in drying mechanism of a gravure printing machine by applying the fluid dynamics and aerodynamics theories. The kinematical equation and the kinetic equation were established respectively and the RNG model was added according to flowing conditions of hot air. The CFD analysis model was established by adopting the computational fluid dynamics (CFD) method to implement dynamic simulation analysis on air hot in the drying mechanism. Uniformity of drying was improved through adding clapboard and a flow guide plate to optimize the structure of air nozzles, so that the hot air convolutes for multi times on substrate and the utilization efficiency was increased.
