【摘要】 目的针对市场上常见的条码打印机不能进行自动贴标,打印出的标签需要由人工进行贴标,标签不美观也不卫生的问题,设计并制造一台自动试管贴标机。方法利用CATIA软件对试管贴标机进行三维建模,利用Ansys软件对贴标机的薄弱环节——副辊进行静力学分析,研究副辊的应力及变形情况。然后对组成试管贴标机的零件进行采购和加工,并进行装配。最后对直径为12 mm的试管进行贴标试验。结果试管贴标机中主辊电动机和回转轴电动机的转速分别为650 r/min和195r/min时,试管的线速度能与条码打印机出纸的速度相匹配,能够正确地进行贴标。结论试管贴标机理论上是正确的,能够实现高效、准确地贴标。更多还原

【Abstract】 Objective To solve the problems that general barcode printers in the market could not label automatically,the printed label is labeled by hand,and the label is neither beautiful nor sanitary,an automatic tube labeling machine was designed and manufactured. Methods The tube labeling machine was modeled by CATIA software. The vice- roll,which is the weakest part of labeling machine,was analyzed in statics by Ansys,and the stress and the deformation of the vice- roll were investigated. Then the components were purchased and processed,and the labeling machine was assembled. At last,tubes with a diameter of 12 mm were labeled by the tube labeling machine. Results When the speeds of the main roll and vice- roll motor were 650 r / min and 195 r / min respectively,the linear velocity of the tubes can match with the paper- out speed of the barcode printer,and the labeling machine could label accurately. Conclusion The tube labeling machine is correct in theory, and it could label efficiently and accurately.更多还原
