Study on the Structure Optimization and Simulation Analysis of Oven System in Gravure Press

Based on traditional gravure press drying system in the uneven distribution of internal hot air oven, drying problem such as low efficiency and large energy consumption, refer to the original structure of the wind drying oven design experience, design a kind of adjustable air nozzle, optimize the structure of original oven, at the same time in the middle of the oven and wind mouth entrance increase wind plate uniform, chamfering is set in the oven outlet. In this way, the hot air reaching the inlet of the air nozzle, the outlet of the air nozzle and the surface of the base material is more uniform, improving the drying efficiency of the oven, saving energy and reducing consumption. CFD simulation software was used to establish the fluid domain model of air nozzle and oven. Simulation analysis was carried out on the adjustable air nozzle and the whole oven before and after optimization, and the velocity values of key parts were extracted for numerical analysis. Finally, the oven structure with the highest drying efficiency was obtained. The experimental platform of oven system was built, and the results of the optimized oven were verified experimentally. The simulation results are basically consistent with the experimental data analysis results.
