The invention relates to a pneumatic hole burning machine, and belongs to the technical field of plastic woven bag hole burning. The machine comprises a rack (1) and a cylinder (1); the machine is characterized in that a tool mounting frame is installed on the rack (1), the middle of the tool mounting frame is fixedly connected with the lower portion of a piston rod (6) of the cylinder (2), multiple heating tools (5) are installed on the lower end face of the tool mounting frame which is provided with a rotating shaft (9) driving the tool mounting frame to rotate, and the rotating shaft (9) isconnected with a motor (3) through a transmission mechanism (3). Accordingly, a traditional hole burning machine structure is changed, the multiple heating tools can be installed through the tool mounting frame, then burning of multiple holes is completed simultaneously by cooperating with the same action of the cylinder, and the work efficiency is improved; one side of the tool mounting frame isconnected with the transmission mechanism, by means of the transmission shaft and the rotating shaft, the tool mounting frame and the multiple tools installed on the upper portion of the tool mounting frame can be driven to rotate together, and hole burning positions of the heating tools can be rotationally adjusted according to the arrangement rules of the multiple heating tools arranged on thetool mounting frame.
