A driven gear 19 is respectively fixed at the front and rear ends of each housing 3 at the outer side of the tin plate 1, an outer gear ring 20 is rotatably connected to the front side of the annular block, the outer gear ring 20 is engaged with each driven gear 19, and the outer gear ring 20 is driven to rotate by a motor; A rotating shaft 21 is fixed in the middle of the tin plate 1, and a fixedly placed motor is arranged at the rear end of the rotating shaft 21. The rotating shaft of the motor is fixedly connected with the rotating shaft 21, and the motor can drive the tin plate 1 to rotate through the rotating shaft 21. The outer end of the needle 5 and the housing 3 are bent at a certain angle of inclination in the radial direction, and all the needles 5 on the same housing 3 have the same bending angle and bending direction, and the needles 5 on the left and right sides of the tin plate 1 are bent in the opposite direction. The cleaning mechanism comprises a roller 22 arranged horizontally in front of and behind an axis. The outer edge surface of the roller 22 is uniformly distributed with bristles. When the housing 3 rotates to a lower end with the cylinder disc 1, the bristles can contact the outer edge surface of the housing 3, and the roller 22 is driven by a motor to rotate around the axis all the time.

The napping roller 2 can perform napping operation on the lower end face of the cloth, specifically, When the shell 3 rotates in the upper part of the cylinder plate 1, the slide rod 12 and the pulley 18 are always located closer to the inner side of the shell 3 under the limiting action of the annular chute 10, and all the long rods 6 are always located at the nearest position to the inner edge of the shell 3 under the extrusion force of the conical surface on the front side of the cylinder block 7. All the needles 5 protrude the maximum length from the outer edge of the shell 3, which can roughen the inner end face of the cloth. During the roughening process, As the needle drags and destroys the fiber on the cloth surface, cotton fiber and thread residue will be left in the interval of needle 5. When the housing 3 rotates to the lower side with the cylinder disc 1, the annular sliding groove 10 deflects to the outside, and the slider 12 and pulley 18 drive the cylinder block 7 to move outward relative to the housing 3.

When the housing 3 passes through the roller 22, The bristles on the outer side of the roller 22 can wipe off the cotton wool around the needle 5. When the housing 3 continues to rotate with the tin plate 1 to the upper side, because the annular chute 10 resets to the inner side, the slider 12 and the pulley 18 drive the cylinder block 7 to continue to move relative to the housing 3 to the inner side. Under the compression force of the conical surface at the inner end of the cylinder block 7, the long rod 6 continues to move close to the inner edge of the housing 3, so that the needle 5 resets to the outer side of the pinhole 4 again, Continue to contact with the inner end of the cloth for napping. In the present invention, the fixed tube 15 restricts the moving direction of the pull rope 13, so that the long rod 6 can be pulled to move toward the inner edge of the housing 3 when the cylinder block 7 moves outward. By changing the different positions of the annular chute 10 at the upper and lower parts of the annular block 8 and the different distances from the longitudinal plane of the annular sunk groove 9, the slide rod 12 and the pulley 18 can drive the cylinder block 7 to move outward at the lower position and drive the cylinder block 7 to move inward at the upper position, It not only does not affect the revolution of the tin plate 1 and the rotation of the napping roller 2, but also can realize the shrinkage and extension of the needle 5 in the pinhole 4, so that the existing napping structure is slightly modified, the napping effect is not affected, and the blockage cleaning is more convenient; The internal and external movement of the needle 5 can collect the cotton and thread ends in the gap of the needle 5 in the front end of the needle 5 under the blocking effect of the outer edge surface of the housing 3, which is convenient for the roller brush to centrally brush the blockage and greatly improve the cleaning efficiency of the roller brush.
