Research On The Multi-Conical Surface Of Forming Shoulder

Forming shoulder has the direct influence on the packaging quality, which is already widely used in packaging engineering as an important part of forming, filling and sealing packaging machine. So it is important to study on it.In order to study more on the forming shoulder, optimize the performance of the existing forming shoulders, this article focuses on the new multi-conical surface type of the shoulder based on previous studies, mainly include three kinds of multi-mode conical shape.Because the forming shoulder is a developable surface , we can establish the mathematical model of the bending curve, the working surfaces, the boundary curves of every forming shoulder, and obtain their 3-dimensional model using Pro/E software to verify the model's accuracy.Comparing the performance of this three models,including sealing method, the model allows changes in height and curvature of the bending curve, then we can obtain the optimization model; according to the difference between the production manufacturing process and the fundamental research and on the basis of the theory of the offset bending curve we can ontain the offset bending curve of the optimization model. and established their three-dimensional model.On the basis of the previous studies,we focus on the mathematical model of the complex ross-section of multi-cone forming shoulder,and established their three-dimensional model under Pro/E.This article is mainly study on the multi-conical surface type of the shoulder which is based on the traditional shoulder. This research has improved the sealing method and the model allows changes in height, has important significance to the study on the forming shoulder,and has enriched the existing forming shoulder's type.
