弧面分度凸轮机构在YB47型硬盒包装机包装轮中的应用

YB47型硬盒包装机包装轮的间歇运动对机器造成的冲击,易使包装轮包装过程产生铝箔纸破损或铝箔纸缺失现象.为此,利用弧面分度凸轮机构在高速运动中的高精度分度功能,应用于3号包装轮的驱动机构中,采用弧面分度凸轮机构代替槽轮机构,以减少分度机构对机器造成的冲击.应用效果表明,采用该机构的3号包装轮分度精度高,定位准确,传动平稳,结构紧凑,装配弧面分度凸轮机构步骤简化,操作方便.与YB45型硬盒包装机3号包装轮相比,YB47型包装机中的弧面分度凸轮机构有效减少了3号轮在高速运动中的振动和对机器的冲击；与YB45小包铝箔纸缺陷数据相比(5～9包/月),改进后YB47在3号轮包装过程中未出现铝箔纸破损或铝箔纸缺失现象,提高了烟包包装质量.

Application of Indexing Curved Cam Mechanism in Packaging Wheel of YB47 Hard Packer

The impact caused by the intermittent movement of packaging wheels in YB47 hard packer sometimes resulted in foil breakage or out of place,therefore the actuator was replaced by an indexing curved cam mechanism in No.3 packaging wheel of YB47 to reduce the impact.The practical application indicated that the improved No.3 packaging wheel featured high indexing precision,accurate positioning,smooth transmission,and it is compact in structure,simple in assembling the indexing cam mechanism and convenient in op...
