Abstract:The component feed screw can complete the actions of increasing distance, reducing distance, diverging, merging, lifting, undulating, turning of regular or irregular batch packaging containers. Based on SolidWorks software, the steering screw design of complex bottle type was completed by using the principle of generating method. The operation process was modeled, and the screw design of the new bottle could be completed by directly modifying the corresponding model. Through the comparative analysis of the rotational acceleration curve, a suitable rotational curve was provided. At the same time, modeling error and transportation stability were analyzed.
