Optimization Research of the Developing Machine Structure Based on Fluent

Abstract

Because of good and fine printing quality, screen printing is very common technology in printing and dyeing factory recently. Developing is important to insure the screen printing quality. In this paper, a developer structure is designed and studied. Fluent software is used to analyze the developing process. In this way, the numerical model of nozzle is founded. The jet flow fields of different structure fan-type nozzles are analyzed and compared. Depended on the simulation results, the right nozzle is chosen and used in the developer structure, and the structure of developer is modified to fit the cleaning quality required. The experiment of new structure developer with the chosen nozzle is done, and the experiment result shows better cleaning quality with the new developer and new nozzle.
