The invention discloses a dust suction assembly of a textile machine. The dust suction assembly of the textile machine comprises a bracket, a dust blowing pipe, a dust cover, two exhaust fans and a dust collector, wherein the bracket is arranged above the textile machine, and the dust cover is arranged on the top of the bracket; the tail of the dust blowing pipe is communicated with a blower through a bubble pipe, and the head of the dust blowing pipe is detachably provided with a blowing head; the blowing head blows dust toward the bottom surface of the dust cover, and the two exhaust fans are installed at both ends of the top surface of the dust cover separately; the air outlet of each exhaust fan is communicated with one end of an exhaust pipe, and the other ends of the exhaust pipes are communicated with each other in an intersection mode, and are connected with the dust collector, so that the dust collected at the bottom of the dust cover can be sucked by the exhaust fans to the dust collector for collection along the exhaust pipes. The dust suction assembly of the textile machine is simple in structure and convenient to use, the cleanliness of a textile workshop is ensured, and meanwhile the threat of the health of workers from the dust can be avoided.
