Monomer suction device of spunbonded non-woven fabric production line

The utility model provides a monomer suction device of a spunbonded non-woven fabric production line. The monomer suction device of the spunbonded non-woven fabric production line comprises a suction head, a pressure stabilizing pipe and a centrifugal fan. A perforated plate is arranged on one end face of the suction head. A flow guiding piece is arranged in the suction head and corresponds to the perforated plate. A plurality of horn-shaped suction flow channels are further arranged in the suction head. The big-opening end of each horn-shaped suction flow channel corresponds to the corresponding flow guiding piece. The small-opening end of each horn-shaped suction flow channel corresponds to a first suction pipe. The suction head is communicated with the pressure stabilizing pipe through the multiple first suction pipes. The pressure stabilizing pipe is communicated with the centrifugal fan through a second suction pipe. By the adoption of the monomer suction device of the spunbonded non-woven fabric production line, the accumulation amount of monomer micromolecules on a spinneret plate is greatly reduced, the service life of the spinneret plate is effectively prolonged, the stability of spinning is guaranteed, stability of suction airflow is guaranteed through the arrangement of the perforated plate and the flow guiding pieces, and adverse effects on a tow are avoided.
