摘要
为解决烟草制丝行业中粉尘大、维护保养不便问题,提高烟草制丝的生产效率和设备保养效率,构建了一种针对烟草用电子皮带秤侧板开合的连杆机构模型,并在此基础上对秤台其他部分进行结构优化。首先分析现有烟草用电子皮带秤的结构和实际生产情况,模拟护板闭合与开启状态建立了2种模型,并结合电子皮带秤内部实际尺寸进行计算校核;然后优化称重传感器连接部件和秤体支撑部件,建立优化后的传感器支撑与U型支撑组件模型,并与原有模型对比,阐述其优点;最后进行有限元静力学分析,比较新旧2种结构的静力学计算结果。结果表明,优化后的传感器支撑结构最大应力与应变远小于现有结构,进一步验证了烟草用电子皮带秤结构优化的重要性与新传感器支撑的可用性。开合用连杆机构模型与相应部件的结构优化为烟草行业电子皮带秤的后续发展提供了一种新的方案。
In order to solve the problems of heavy dust and inconvenient maintenance in the tobacco silk processing industry,and improve the production efficiency of workers and equipment maintenance efficiency in the tobacco silk making process,a connecting rod mechanism model for the opening and closing of the side plate of the tobacco electronic belt scale was constructed,and the structure of other parts of the scale platform was optimized on this basis.This connecting rod model analyzed the structure deficiency and the actual production situation of the existing electronic belt scale for tobacco,and established two different models to simulate the closing and opening of the guard plate.The connecting parts of the weighing sensor and the supporting parts of the weighing body were optimized,and the optimized model of the sensor support and U-shaped support module was established,and its advantages were compared with the original model.On this basis,the finite element statics analysis was carried out,and the statics calculation results of the new and old structures were compared.The results showed that the maximum stress and strain of the optimized sensor support structure was much smaller than that of the existing structure,which further confirmed the importance of structural optimization and the availability of the new sensor support.The connecting rod mechanism model for opening and closing and the structural optimization of corresponding components provide a new scheme for the subsequent development of electronic belt scale in tobacco industry.
