Abstract
The work aims to design a new intermittent motion mechanism of fixed cam linkage to fulfill the intermittent paper feeding function of high-speed die cutting machine. Firstly, the working principle and the combination block diagram of the intermittent mechanism were analyzed. Secondly, after the motion continuity of a fixed cam five-bar mechanism was studied, the bar length of the intermittent mechanism was determined according to motion continuity conditions. Thirdly, a profile curve of fixed cam was designed by generating the entity with relative trajectory curves in ADAMS software. Finally, the kinematics analysis on the intermittent mechanism based on simple harmonic motion, cycloid motion and quintic polynomial motion was carried out separately. The intermittent mechanism of fixed cam linkage based on quintic polynomial not only fulfilled the expected dynamic and static ratio, but also was stable in high-speed operation. The intermittent mechanism of fixed cam linkage has good kinematic performance and can meet the working requirements of high-speed die cutting machine.
