By starting the servo motor 2 to rotate forward, multiple yarns can be wound together through the connection of the driving gear 4, the driven gear 5 and the round seat 6. Then, the servo motor 2 is reversed, and the yarns can be reversely wound together, so that the yarns are short and curved, which increases the tensile properties of the yarns without destroying the structural strength of the yarns. The socks fabric woven with yarns with small bends at intervals is soft. When the power output shaft of the servo motor 2 rotates, the rotating shaft 3 fixed to the shaft end of the power output shaft of the servo motor 2 can be rotated, thereby rotating the driving bevel gear 81 fixed on the rotating shaft 3. , and then the driven bevel gear 82 meshing with the active bevel gear 81 can be rotated, so that the bent rod 83 can be rotated. Under the rotation of the bent rod 83, the piston 85 can be connected by the sleeve rod 84 movably sleeved on the bent rod 83 to slide back and forth up and down in the inner cavity of the cylinder 86. Through the connection of the bent pipe 88, the fluff produced by the kneading can be sucked into the inner cavity of the fluff collection box 87 through the dust suction head 89 and fall on the top of the filter screen 873 under the connection of the hose 891, so as to avoid inhalation by the staff and improve the safety of the device. Under the rotation of the bent rod 83, the cam 91 fixed on the bent rod 83 can be rotated. Under the connection of the mounting plate 92, the angle of the dust suction head 89 can be deflected under the action of the torsion spring 941, thereby increasing the adsorption range of the dust suction head 89 and improving the effect of sucking fluff.
