Topology analysis and structure optimization of the heat-sealing knife of the bagging machine

Abstract:

In order to reduce heating waiting time of the heat-sealing knife, and concentrate energy generated by the heating tube on the contact surface of heat-sealing film, the structure of heat-sealing knife in the packaging machine is improved. First, establish the temperature field model of heat-sealing knife and verify the accuracy of model. Then, use the goal-driven optimization tool in Ansys Workbench to optimize the specific size of heat-sealing knife. Next, use the Genesis module in Ansys Workbench to perform topological analysis and optimize the structure of heat-sealing knife. On the basis of the optimization of the two, the simulation experiment was carried out by trial and error method, and the size of the heat-sealing knife was gradually adjusted. Finally, under the condition that the quality of the sealing film is guaranteed and the installation size of the heat sealing knife remains unchanged, most of the energy generated by the heating tube is concentrated on the sealing film contact surface, and the maximum temperature of the sealing film contact surface is increased from 160.25℃ to 330.11℃.According to the result, with the help of Ansys Workbench simulation software, the structure of heat-sealing knife is improved, which can achieve the purpose of reducing heating waiting time of the heat-sealing knife, and concentrate energy generated by the heating tube on the contact surface of heat-sealing film at the same time.
