The auxiliary cloth-carrying roller 533 can move up and down under the control of the cylinder, and can assist the sewing machine to drive the cut-parts to roll when pressing the cut-parts downwards and rolling.

Because the shirt body is longer, the cut pieces of the shirt body are clamped by the U-shaped frame of the cylinder auxiliary rotating device during sewing. During sewing, the cylinder auxiliary rotating device rotates to drive the shirt body to rotate, so that the sewing resistance is reduced.

The deviation of the whole collar and shirt body is mainly corrected by the conical limiting wheel 320.

During sewing, circular collars, shirt bodies or shirt feet and the like are sleeved on the edge control cones at two ends, the conical limiting wheel 320 is driven to rotate by rotary power, and due to the conical shape of the conical limiting wheel 320, force towards the direction of the limiting plate 340 is generated on the cutting pieces when the conical limiting wheel 320 rotates, so that the deviated cutting pieces gradually move towards the direction of the limiting plate 340 along with the rotation of the conical limiting wheel 320 until being propped by the limiting plate 340, and the positioning is realized.

The round slope surface is added, so that the cut pieces are staggered or retracted and are limited by the angle formed between the round slope surface and the cone, and the cut pieces are in a folding effect and do not slide in any direction, so that the cut pieces are kept aligned at the edge in the whole sewing process. So that the sewing effect is better.

The conical limiting wheel 320 plays an integral role in correcting the deviation of the circular collar and the shirt body, but the distance between the conical limiting wheel 320 and a sewing needle of a sewing needle device is far in the sewing process, and the deviation correction of the double-layer cloth of the collar part is matched with a cut-part edge control device 500. Collar portion is close to clothing sewing needle position and is packed in cut-parts accuse limit device 500 during sewing, down in the material passageway 270, cut-parts accuse limit device 500's first blast pipe 250 and second blast pipe 260 are bloied, blow out after coming out to blow in the material passageway 270, the edge of the cut-parts in the material passageway 270 will be crossed is fixed a position, in order to prevent to blow too much to make the cut-parts arch up in passing material passageway 270 the inside, first air-out groove 221 and second air-out groove 241 have been set up in order to be used for the wind, discharge too much wind, guarantee that the cut-parts are leveled.

The sensing component 520 is used for controlling the edge position of the cut piece, the mop wheel 531 is not pressed on the cut piece at ordinary times, and when the sensing component 520 senses the deviation of the cut piece, the mop wheel 531 presses down and rotates to correct the position of the cut piece after receiving a signal. The circumferential edge of the driving bull wheel of the mop wheel 531 is uniformly provided with rollers 533, and the rollers 533 can rotate along the circle center of the rollers.

The surfaces of the mop wheel 531 and the small-circumference roller 533 are smooth to ensure that the filaments on the surface of the cut pieces are not caught during the mop process. When the mop wheel 531 is used for correcting deviation, certain resistance is provided for the forward movement of the cut pieces, and when the cut pieces are knitted cut pieces, the cut pieces are easy to deform and stretch, so that the sewing effect is influenced. Therefore, the roller 533 which can rotate along the center of circle of the mop wheel 531 is added on the circumferential edge of the mop wheel 531, when the cut piece moves, the friction force between the mop wheel 531 and the cut piece is reduced by the rolling of the roller 533 and the smooth outer surfaces of the mop wheel 531 and the roller 533 when the mop wheel 531 presses the cut piece, so that the cut piece can rotate more smoothly in the sewing process.
