[0027] Working principle: align the dust suction port 2 with the working position of the circular knitting machine, start the air pump 1, and the dust and fluff generated during knitting will enter the second connecting pipe 4 along the dust suction port 2, and then enter the inside of the connecting sleeve 5, and be blocked by the filter 12. At this time, the driving motor 7 is started, and the transmission ring 15 and the transmission ring 2 17 cooperate with the transmission belt 18 to drive the support rod 13 to rotate. The filter 12 ensures the rotation stability of the support rod 13. The rotation of the support rod 13 causes the pointed cone 16 to rotate, and the dust and fluff accumulated in the connecting sleeve 5 are entangled and concentrated, while the air passes through the filter 12 and the first connecting pipe 3 normally, and is finally discharged from the air outlet of the air pump 1. When the knitting work is completed, until Rotate the two extension tubes 6. Since the threaded ring 11 is rotatably connected to the threaded groove 9, the extension tube 6 automatically shrinks toward the inside of the connecting sleeve 5, completing the removal of the connecting sleeve 5. Then rotate the nut 14 to separate it from one end of the support rod 13, and then remove the support rod 13. Finally, clean the dust and fluff wrapped around the outside of the cone 16 and the dust and fluff adhered to the surface of the filter screen 12. Then, pass the support rod 13 through the filter screen 12 again, reposition it through the nut 14, and rewind the lower end of the transmission belt 18 around the outside of the transmission ring 15. Then, fix the two clamping grooves 10 to one end of the first connecting tube 3 and one end of the second connecting tube 4, respectively, and continue to collect dust.
