目的 为了解决成摞纸质金融产品捆扎效果差等问题。方法 通过对一代结构机进行设计、实验，以及对二代结构机进行优化设计，完成捆扎条传送、产品定位与捆扎条烫接、捆扎条裁切、捆扎条折纸及勉纸等机构的模块化设计。结果 该捆扎机能自动实现捆扎条的定长传送、定长裁切、折纸及烫接；当出现故障时，可实现线下维修，能够将因停机维修造成的损失降到最低。还能根据不同产品厚度自适应调整折纸位置，实现捆扎百张纸质金融产品松紧一致的目标。结论 经过实际应用，文中研究的自动捆扎机工作可靠、运转良好，具有推广价值。

The paper aims to solve the problem of poor strapping effect of stacks of paper financial products. The conveyor mechanism, product positioning and ironing mechanism, cutting mechanism, origami mechanism and scrap mechanism of the automatic strapping machine was researched in modules through design and test on this generation of structural machine and optimizing and design on the second generation of structural machine. The strapping machine could automatically realize the fixed length transmission, fixed length cutting, origami and ironing of the strapping; when a fault occurred, the offline maintenance could be realized, and the loss caused by the shutdown maintenance could be minimized. The origami position could be adaptively adjusted according to the thickness of different products to achieve the tightness of the bundled paper financial products. The practical application shows that the automatic trapping machine researched in this paper works reliably, runs well and worth popularization.
