A support frame is fixedly supported on the top of the table body. A plurality of bases are fixedly arranged at equal intervals on the top of the table body. A cloth roller is arranged in each of the plurality of bases. A cylinder is installed at the center of the top of the support frame. A moving plate is fixedly connected to the power output end of the cylinder. The moving plate is located below the support frame. It also includes a threaded rod and a rotating block. The cutting blade is fixedly connected to the rotating block through a mounting plate. For the cutting device for a projectile loom of the utility model, through the settings of the threaded rod, the moving motor and the rotating block, it is convenient for the cutting blade to move horizontally, so as to facilitate the cutting blade to cut multiple pieces of woven fabric in a short time, further improving the practicability and processing efficiency of the cutting device.
