[0021] Working principle: When using, place the cotton roll 111 and the yarn roll 113 into... Figure 2At the indicated position, one end of the cotton roll 111 passes through the upper end of the hand-operated roller 109, then through the lower end of the shaping roller 108. One end of the yarn roll 113 passes through the lower end of the roller shaft and through the lower end of the hemming nylon wheel 102, then enters the lower end of the shaping roller 108 and overlaps with the cotton roll 111. The material consisting of the cotton roll 111 and the yarn roll 113 is then conveyed by the conveyor belt 107. It then passes through the middle of the drive roller 104 and follower roller 106, and through the lower end of the traction roller 105, then enters the automatic tape cutter 211 of the sewing assembly 2. The automatic tape cutter 211 then cuts and segments it, and then... The material picking guide block 208 moves on the material picking guide rail 210, thereby causing the material picking guide block 208 to drive the gripper cylinder to move, so that the gripper cylinder clamps the material to the upper end of the feeding plate 207. Then, the pressure plate 209 moves on the upper end of the pressure guide rail 206. With the cooperation of the liftable pressure plate 209, the material is conveyed to the lower end of the placement frame 212. Then, the servo motor 203 drives the pulley 215 to rotate, thereby driving the feeding belt 213 to move, thus conveying the material. At the same time, the material is sewn by the reverse overlock machine 205, and then conveyed to the folding assembly by the support plate 214. The material moves along the upper end of the ribbed belt 310, and then the drive motor 309 drives the supporting roller 311 to rotate, thereby moving the ribbed belt 310 and the material. Then, the material-grabbing guide block 304 moves on the upper end of the material-grabbing guide rail 306, thereby causing the clamping cylinder 303 to drive the material-grabbing clamping plate 305 to move the material to the upper end of the first conveyor belt 307. Then, the first conveyor belt 307 conveys the material. When it moves to the lower end of the first folding frame 302, the fourth electric telescopic rod drives the first insert plate 308 to descend, so that the first insert plate 308, together with the two first conveyor belts 307, feeds the material into the first folding frame 302. The material is initially folded and falls through the gap between the two first conveyor belts 307. Then, the second conveyor belt 323 transports it to the lower end of the second folding frame 313. The third insert plate 321 is then extended by the first electric telescopic rod 312, which folds the material again. The material then falls into the upper end of the third conveyor belt 324 and is transported by the third conveyor belt 324. The baffle plate 315 is then extended by the second electric telescopic rod 314 and is processed again by the flip plate 316. Finally, the material flows into the interior of the first receiving hopper, the second receiving hopper 318, and the third receiving hopper 317.
