The invention relates to the technical field of filter material manufacturing equipment, and discloses an ultrasonic composite perforating machine, which comprises a rack, a plurality of ultrasonic generators are arranged above the rack, the output ends of the ultrasonic generators are connected with a hot pressing block, sound waves are transmitted by the hot pressing block, a perforated paper roller is arranged below the rack, protruding points used for perforating the composite filter paper are arranged on the outer wall of the perforating paper roller, and a chain wheel mechanism is further arranged on the rack and driven by a motor to drive the perforating paper roller to rotate. The ultrasonic composite perforating machine has the advantages that the ultrasonic composite perforatingmachine can be suitable for composite work of an environment-friendly supporting composite material which is researched and developed by a company and used for manufacturing filter paper for a filter,the composite effect is strong, cracking and gaps are not generated after folding, required discrete holes can be perforated during composite work, and the ultrasonic composite perforating machine isconvenient to use, safe and easy to adjust; and the compounding steps are reduced.
