Research On Some Key Problems In Amyloidal Tableware Product Line

Optimal mould structure and high efficient heating method are the decisive factors in the product quality, operational performance and working cost of an amyloidal tableware product line. The research object of this thesis is the amyloidal tableware product line type LW501, and it mainly discusses the key technologies introducing microwave heating method to environmental protection tableware production line, and the finite element analysis and structural optimization design of mould frame with ANSYS software.Firstly the characteristics of microwave heating technology and its application status at home and aboard are analyzed, then combined with the special needs of the tableware production line, technological scheme of the microwave heating system is given, including the detailed design of important components of the microwave heating system. Secondly by a microwave heating experiment the distribution rules of the microwave power fielding in a microwave oven cavity are illustrated and then some methods to obtain a more uniform heating field are put forward. Mould frame is a very important component in the production line. It must be rigid enough to resist the enormous force generated by the sparking material, at the same time it must be simply and light, which makes the manufacturing and the running of the product line easier. In the thesis, we obtained the deformation results of the mould frame by finite element analysis with ANSYS. As the great difference of the deformation results at different positions, we carried out two sizing optimizations and a topological optimization with ANSYS optimization module based on the studies of optimization theory. In the sizing optimization, we obtained a more rigid structure with weight not changed, and a lighter structure with the same deformation as the origin design by setting different objective functions. By applying the topological optimization to the mould frame, we get the material distribution trends, and follow the trends two new structures are brought forward. By finite element analysis the two new structures is proved to be more rigid and practical.
