摘　　要：卷纸上料装置是纸袋生产机械中实现成卷的纸上、下料功能的机械装置。经过一段时间的使用后,该上料装置的摇臂轴受力分析及结构出现强度问题而失效。针对以上出现的强度失效问题,经过对该上料装置的摇臂轴进行理论分析和计算,查找其结构尺寸的不合理环节,并进行优化设计。最后,基于有限元法对该装置的原结构和优化后结构进行建模计算,优化后结构应力小于材料屈服强度,解决了原结构出现的大面积屈服失效问题。The paper roll feeder is a mechanical device in the paper sack production machinery that realizes the functions of loading and unloading rolled paper.After a period of use,the rocker arm shaft of the feeder fails due to stress and structural strength problems.In view of the above strength failure problems,through theoretical analysis and calculation of the rocker arm shaft of the feeder,the unreasonable aspects of its structural dimensions are identified,and the design is optimized.Lastly,based on the finite element method,the original structure and optimized structure of the feeder are modelled and calculated,and the stress of the optimized structure is less than the yield strength of the material,which solves the large-are a yield failure problem of the original structure.
