The invention discloses an intelligent curtain driving mechanism. The mechanism comprises two fixing supports and a roller. The two fixing supports are symmetrically arranged on the two sides of the roller correspondingly. A first motor shell is fixedly mounted on one fixing support through a connecting plate. A second motor shell is fixedly mounted on the other fixing support through a connectingplate. A first motor is arranged in the first motor shell. The first motor drives a hollow annular iron block to move, accordingly, stainless steel rods can be inserted into circular grooves correspondingly, therefore, a first cylindrical iron block is fixed, accordingly, the roller is prevented from rotating, accordingly, a curtain does not slide downwards under the effect of self gravity, and it is guaranteed that the curtain can be maintained stable; and the mechanism is connected to the fixing supports through the connecting plates during mounting, in addition, the connecting plates are connected with the fixing supports in an inserting mode, and an operator can mount or dismount the mechanism conveniently.
