The present invention provides a constant force multiple spring curtain winding system, including a mounting bracket fixedly connected to a wall, and a revolving drum connected to a curtain, wherein one end of the mounting bracket is connected to a rotating rod through a speed change mechanism, a constant force spring mechanism fixedly connected to the revolving drum is arranged on the rotating rod, and the rotating rod is fixedly connected to a constant force elastic piece in the constant force spring mechanism. According to the present invention, a speed of the revolving drum is adjusted by the speed change mechanism, and the rotating rod rotates at a low speed by the speed change mechanism when the revolving drum rotates at a high speed, thus ensuring that the revolving drum rotates for enough turns to meet a height of the curtain, maximizing a width of the curtain and reducing a counterweight of a lower rail of the curtain; and the requirement on the size of the curtain is met by increasing or decreasing the number of the constant force spring mechanisms, and the curtain is capable of staying at any positions. The constant force multiple spring curtain winding system is novel in structure, simple to operate, wide in application and easy to popularize.
