The initial tension is too small. The tension at the separation point of the belt and the roller is not enough. This situation generally occurs at startup.
The friction between the roller and the conveyor belt is not enough. The reason for this is most likely that there is water on the conveyor belt or the environment is humid.

The load of the conveyor belt is too much.
Low temperatures, cold temperatures can reduce the grip between the pulley and belt.
Improperly installed pulley lagging
