Power system of belt conveying line

The invention discloses a power system of a belt conveying line, and solves the problem of belt fold or slip. The power system is characterized in that a driving shaft and a driven shaft are both driven by motors and a speed reducing mechanism. A driving motor for driving the driving shaft and a driven motor for driving the driven shaft synchronously operate, and cooperate to act on a belt. Therefore, the service life of the belt can be prolonged, and the whole system is more stable and reliable in operation.
