A roller wheel tower with two plate cam drives fixed to the input shaft, featuring a mechanism design with parallel conjugate cams. It achieves the function of dividing the output shaft by rotating the roller wheel tower through the rotation of the two plate cams mounted on the input shaft, suitable for conveying belts with larger pitches or for intermittent divisions with longer dwell times. Additionally, the three-piece heavy-duty model is more suitable for rapid and long-pitch conveyances, with a longer dwell time than the two-piece model.
