A transmission device in which the plate CAM on the input shaft engages parallel with the driven roller on the indexing wheel of the output shaft. The splitter has a structure design of parallel conjugate CAM. Suitable for supplying conveyor belt drive with larger pitch or for intermittent indexing with longer residence time. The divider can realize the output of small division and large distance. It is especially suitable for occasions requiring fewer stops within a cycle, such as various carton die-cutting machines, fruit milk jelly filling and forming machines.
