The invention discloses a direct-drive type active cam shedding mechanism. The mechanism comprises direct-drive cam devices connected on a harness frame through connection rods, wherein each connection rod comprises a first connection rod and a second connection rod, one end of the first connection rod of each connection rod is connected with the corresponding direct-drive cam device, the other end of the first connection rod of each connection rod is connected with the front end of the corresponding second connection rod, and the tail end of the corresponding second connection rod is connected with the harness frame. According to the direct-drive type active cam shedding mechanism, transmission is simple and reliable, a few of moving members are required, light-weight transmission is realized, motion friction pairs are reduced, friction loss is reduced, the rotation speed of a loom is much increased and cannot be reached by a single-cam shedding device, the stress condition of cams is improved, the service life of the cam shedding mechanism is prolonged, and a width-breadth loom can realize high-speed shedding.
