The work aims to analyze the working principle of the NEWTOP high-speed intelligent paper cup machine, study the overall forming process of paper cups and the operating rules of each mechanism, design an indexing mechanism with globoidal cams that meets the requirements of the NEWTOP high-speed intelligent paper cup machine, and verify its rationality through simulation analysis. A conjugate coordinate system was established to calculate the surface equation. The SOLIDWORKS software was used to establish the model of the globoidal cam indexing mechanism. The UG software was employed to conduct kinematic simulation analysis on the globoidal cam indexing mechanism, and the Origin software was used for data sorting. The angular displacement of the turntable could precisely achieve seven-station indexing and positioning. Its angular velocity curve changed smoothly, ensuring the stability of the mechanism operation. Meanwhile, the angular acceleration curve fluctuated within a reasonable range, avoiding excessive shock and vibration. By analyzing the graphs of angular displacement, angular velocity, and angular acceleration of the turntable of the globoidal cam mechanism, it is verified that this globoidal cam indexing mechanism can enable the seven-station precise stop of the main rotating tower forming mechanism, which is in line with the design requirements, meets the expected design, and ensures that the NEWTOP high-speed intelligent paper cup machine can operate at high speed and stably.
