针对折页滚筒夹板机构在运行时存在的磨损、冲击以及噪声等问题，建立了折页滚筒夹板机构的运动方程，并对其进行了运动学分析。研究表明，机构中凸轮廓线设计不够合理和机构运动存在加速度突变，是导致机构存在磨损与冲击的主要因素。为折页滚筒夹板机构的改进设计提供了分析依据。

There are some problems with splint mechanism of folding roller in operation, such as big abrasion of cam, big impact and noise. Kinematic analysis equations of splint mechanism of folding roller were established and the analysis was carried out. The results showed that the main reasons of abrasion and impact are irrational cam profile of the mechanism and mutation of acceleration in operation process. The purpose was to provide analysis basis for improvement of the splint mechanism.
