包芯线自动包装机的设计与分析

目的针对手工包装包芯线卷效率低和包装质量参差不齐等问题,设计一种最大质量为1500 kg的包芯线卷自动化包装机。方法根据包芯线卷的主要参数和包装工艺流程,结合包芯线卷在包装过程中的实际要求进行包装机的结构设计,包括包膜准备装置、热封装置、焊接系统、气压系统。结果设计出了完整的总体尺寸为3200 mm×1200 mm×2000 mm的包芯线卷自动包装机,完成了包装机模拟装配仿真、气压系统的调试。仿真结果表明,大小膜牵引器速度为0.11~0.5 m/s;关键零部件U形钩的有限元分析结果表明,最大位移发生在U形钩底部,其最大等效应力为29.871 MPa,装置的强度满足设计要求。结论总结包芯线包装目前存在的问题,从满足企业可持续化需求角度对包装机进行了创新设计与仿真优化,实现了包芯线卷自动化、标准化包装,为企业节约了人工成本。

Design and Analysis of Automatic Packaging Machine for Cored Wire

The work aims to design an automatic packaging machine of cored wire coil with a maximum weight of 1500 kg, aiming at the problems such as the low efficiency of hand-wrapped cored wire coil and the uneven quality of packaging. The structural design of the packaging machine was carried out according to the main parameters and packaging process of the cored wire coil and the actual requirements of cored wire in the packaging process, including the packaging preparation device, the heat sealing machine, the welding system and the pneumatic system. A complete automatic packaging machine of cored wire coil with an overall size of 3200 mm×1200 mm×2000 mm was designed. The virtual assembling simulation of the packaging machine and the debugging of the pneumatic system were completed. The simulation results showed that the packaging speed was the speed of the film tractor, i.e. 0.11-0.5 m/s. The finite element analysis results of the U-shaped hook of the key component showed that the maximum displacement occurred at the bottom of the U-shaped hook, and the maximum equivalent stress was 29.871 MPa. The strength of the device met the design requirements. Based on the summary of the existing problems of cored wire packaging, the innovative design and simulation optimization of the packaging machine are carried out from the perspective of satisfying the sustainable demand of the enterprises. Automatic and standardized packaging of cored wire coil is realized to reduce labor cost for enterprises.
