[0033] In the embodiment of the present disclosure, the head end of the inner spiral roller 401 and the tail connecting tube 403 are connected to each other by rotating shaft and driven by a motor. The negative pressure fan 405 is bolted to the outside of the main frame 1. The inner spiral roller 401 reduces the internal space of the dust removal suction tube 4, and the reduced space increases the air flow rate and suction force of the dust removal suction tube 4. The inner spiral roller 401 generates an axial thrust while rotating in a circular direction. The axial thrust generated by the rotation of the inner spiral roller 401 can accelerate the movement speed of the dust on the velvet cloth inside the dust removal suction tube 4 toward one end of the tail connecting tube 403.

[0034] In the disclosed embodiment, the lower part of the main frame 1 and the first outer ring frame 101 on the rear side are welded with a dust removal suction pipe 4, the second outer ring frame 203 is welded with a dust removal suction pipe 4, and the upper guide nozzle 402 is located on the inner side of the first outer ring frame 101 and the second outer ring frame 203.

[0035] Embodiment 2, on the basis of embodiment 1, the inner spiral roller 401 is thicker at one end close to the tail connecting tube 403, and thinner at the other end away from the tail connecting tube 403. The inner spiral roller 401 reduces the air suction space at one end of the dust removal suction tube 4 close to the tail connecting tube 403, and expands the air suction space at one end of the dust removal suction tube 4 away from the tail connecting tube 403, so that the suction force at both ends of the dust removal suction tube 4 is more balanced.

[0036] The working principle of this embodiment is as follows: the cotton feeding roller 202 evenly introduces the polyester washed cotton, and then the polyester washed cotton enters the licker-in roller 201, and the metal needle cloth on the licker-in roller 201 tears the large pieces of fiber into small pieces, and then the cylinder 102 covered with the metal needle cloth combs and oriented fibers, the doffer 301 and the cylinder 102 work closely together to peel off the combed fiber layer, and the movable cover plate 103 combs the dust or short hair therein, and the first outer ring frame 101 and the second outer ring frame 203 are both provided with cotton removal knives, carding plates, cotton guide plates and other components to perform short hair combing and separation operations, and the short hair and dust are sucked away by the dust removal suction pipe 4. When maintenance is required, the rear frame 3 and the front frame 103 are The fixing bolts between the frame body 2 and the main frame body 1 are removed, and the rear frame body 3 and the front frame body 2 slide away from the main frame body 1 along the side slide rails 104 of the main frame body 1, and the distance between the cylinder 102 and the licker-in roller 201 and the doffer 301 increases. The cylinder 102 and the licker-in roller 201 and the doffer 301 are directly exposed to the outside, which is convenient for cleaning and maintaining the cylinder 102, the licker-in roller 201 and the doffer 301 from the axial direction. Compared with cleaning from the front end or the rear end of the cylinder 102, the licker-in roller 201 and the doffer 301, it is more convenient, and the cumbersome disassembly and installation of the rear frame body 3, the front frame body 2 and the main frame body 1 as a whole is avoided, the number of disassembled parts is reduced, and the disassembly and installation time for regular maintenance is shortened;

[0037] The negative pressure fan 405 is started to connect the external connecting pipe 404, the tail connecting pipe 403, and the upper guide nozzle 402 of the dust removal suction pipe 4 to generate suction, and the internal space of the dust removal suction pipe 4 is reduced by the inner spiral roller 401. The reduced space increases the air flow rate and suction of the dust removal suction pipe 4, and the suction of the upper guide nozzle 402 is increased. The inner spiral roller 401 has a spiral structure on the outside, and the inner spiral roller 401 generates an axial thrust while rotating in a circular direction. The axial thrust generated by the rotation of the inner spiral roller 401 can speed up the movement speed of the flannel dust inside the dust removal suction pipe 4 toward one end of the tail connecting pipe 403, thereby reducing the amount of residual flannel dust inside the dust removal suction pipe 4.
