Driving device of flexible belt conveyor

The utility model relates to a driving device of a flexible belt conveyor. The driving device comprises a support and a driving belt assembly. The driving belt assembly comprises a first driving wheel, a second driving wheel and a driving belt, the first driving wheel and the second driving wheel are both rotatably arranged on the support, and the two ends of the driving belt are wound around the first driving wheel and the second driving wheel respectively. Wherein the number of the driving belt assemblies is two, a belt can penetrate through the space between the two driving belts, and the driving belts are attached to the belt. The driving belt can drive the belt to move under the action of friction force between the driving belt and the belt so as to convey materials in the belt. Compared with the mode that a driving wheel makes contact with the belt directly, the mode that the driving belt makes contact with the belt can increase the contact area of the driving device and the belt, and the belt is preven
