On rainy days, the open-air conveyor belt is easy to get wet, and the rollers and idlers of the conveyor are also easy to get wet.
The wet friction coefficient of rubber and metal is relatively small. If the roller is not flexible or the surface of the roller is stuck with material, the force on the conveyor belt on the roller will be unbalanced, or the resistance on the rollers on both sides will be inconsistent. , at this time, the conveyor belt will lose its balance and deviate.
In addition, when the surface of the idler sticks to the material that can be swelled by water, the thickness of the water film between the idler and the conveyor belt will increase, which will easily cause slippage and cause the conveyor belt to deviate.
