[Abstract]:With the rapid development of corrugated paperboard production equipment, under the development trend of green economy, corrugated machine, as the core machine of corrugated paperboard production line, can only develop in the direction of high efficiency and energy saving. Therefore, the independent development of high-speed and high-grade corrugated machine for our corrugated board industry has great significance. In this paper, the corrugated board production technology is studied for corrugated machine, and the related design structure of the high-speed corrugated machine is analyzed according to the problems in the actual production of the high-speed corrugated machine developed independently by the enterprise. Combined with the relevant parameters and data of corrugated machine in actual production, finite element simulation and mathematical modeling are used to analyze and calculate the production problems in corrugated machine, and to find out the root of the problem. Finally, the problems of corrugated machine in the production process are solved by improving the corrugated machine design, and the corrugated machine is reformed to improve the production efficiency and save energy. In this paper, the actual working conditions of the guide paper pressure chamber are simulated and analyzed by FLUENT simulation platform, the velocity and pressure distribution in the guide paper pressure chamber are obtained, and the structure of the guide paper pressure chamber is optimized according to the relevant process requirements. Finally, the structure of guide paper pressure chamber is obtained to meet the requirements of high speed corrugated machine. The mathematical model of steam system of high-speed corrugated machine is established, and the steam flow and pressure drop model are obtained. The problems of traditional and old corrugated machine are analyzed, and the problems are calculated and verified by combining with actual data. Finally, the problem of hydrophobic problem in traditional and old schemes is solved by reasonably arranging the steam path of the system, the steam path of high speed corrugated machine is optimized and the steam profit efficiency is improved. Based on the analysis and calculation of corrugated machine, the paper puts forward some suggestions for optimization and improvement, which provides theoretical basis and reference data for the research and development of high efficiency and energy saving single-sided corrugated machine.
