The invention discloses a pulse type macromolecule material suction machine and an application method thereof, and belongs to the field of machining equipment. The pulse type macromolecule material suction machine and the application method thereof aim to reduce the overflow of dust. The pulse type macromolecule material suction machine comprises a macromolecule hopper, a one-way valve, a macromolecule filter, a vortex fan, an air inlet pipe, an air outlet pipe, a first dust removal cloth bag and a pipe head, wherein the air inlet pipe is arranged on the vortex fan, the air outlet pipe is arranged on the vortex fan, the first dust removal cloth bag is arranged on the one-way valve, and the pipe head inserted into macromolecule materials; and a feed port, a discharge port and an air outlet are formed in the macromolecule hopper. The pulse type macromolecule material suction machine and the application method thereof have the advantages that the macromolecule materials can be provided for equipment, meanwhile, the external overflow of the dust can be greatly reduced, the waste of raw materials can be reduced, and the health of workers can be effectively protected; and in addition, the environment-friendly grade of a factory can be improved.
