The roller wheel tower features a cam-type transmission with two plates fixed to the input shaft, equipped with a mechanism design of parallel conjugate cams. It achieves the function of dividing the output shaft by rotating the roller wheel tower through the rotation of the two cam plates attached to 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 compared to the two-piece design.
