The working principle and the using method of the guide device for automatically sewing the arc-shaped open thread at the lower collar of the shirt of the embodiment are as follows:

according to the guide device for automatically sewing the arc-shaped open thread on the lower collar of the shirt, the movable guide plate 3 is pushed to move towards the fixed guide plate 4 through the elasticity of the elastic limiting mechanism 6, the irregular-shaped cloth 12 (such as an arc-shaped collar) placed in the feeding channel is enabled to be close to the side edge of the fixed guide plate 4 and always attached to the fixed guide plate 4 to form a corresponding folded edge, the collar is pulled to move forwards through the pulling force of the sewing machine, the movable guide plate can always keep extruding the collar, and therefore the arc-shaped folded edge of the collar is automatically sewn;

the collar can accurately enter the guide groove 31 of the movable guide plate 3 by using the arc-shaped guide block 7 overlapped with the movable guide plate;

the thrust of the limiting torsion spring to the movable guide plate 3 is adjusted by the elasticity adjusting mechanism 8, so that the guide device for automatically sewing the arc-shaped open thread on the lower collar of the shirt can be suitable for sewing arc-shaped folded edges of collars with different thicknesses;

the adjusting device 9 is used for controlling the initial distance between the movable guide plate 3 and the fixed guide plate 4, namely, the width of the feeding channel can be adjusted to different sizes, so that the requirements of collar hem sewing with different widths are met; the position of the adjusting device 9 can also adjust the force of the elastic limiting mechanism 6 acting on the movable guide plate 3, that is, within the elastic range of the elastic limiting mechanism 6, a plurality of adjusting modes can be adopted (such as independently adjusting the elastic adjusting mechanism 8 or the adjusting device 9, or adjusting the elastic adjusting mechanism 8 and the adjusting device 9 for matching adjustment); to meet the requirements of hemming and sewing of the cloth 12 with different sizes and thicknesses.

When in use, the guiding device for automatically sewing the arc-shaped open thread on the lower collar of the shirt is arranged on the sewing machine, and the discharge port of the hem channel 41 of the fixed guiding plate 4 is aligned with the needle head of the sewing machine; then, placing the cloth 12 (such as an arc collar) with an irregular shape to be processed in a feeding channel, and when the width of the cloth 12 channel is smaller than the width of the front end of the cloth 12 to be processed, manually rotating the movable guide plate 3 around the positioning shaft 5 by an operator so as to adjust the distance between the movable guide plate 3 and the fixed guide plate 4, so that the side edge of the cloth 12 to be processed enters the hem channel of the fixed guide plate and forms a hem to be sewn;

and the arc-shaped guide block 7 overlapped with the movable guide plate 3 can further ensure that the collar accurately enters the guide groove 31 of the movable guide plate 3.

When the processed cloth 12 is thick, the resistance of the movable guide plate 3 to the fixed guide plate 4 is correspondingly increased, the acting force of the elastic limiting mechanism 6 for pushing the movable guide plate 3 to rotate needs to be increased, an operator can move the movable block 83 of the elastic adjusting mechanism 8 to one side close to the movable guide plate 3 (namely, the movable block moves leftwards in fig. 1) along the telescopic groove 84, so that the elasticity of the elastic limiting mechanism 6 is increased, and the requirement for the thrust required by the rotation of the movable guide plate in the sewing process of the corresponding cloth 12 is met. On the contrary, when the processed cloth 12 is thin, the operator can move the movable block 83 of the elastic force adjusting mechanism 8 to the side far away from the movable guide plate 3 (i.e. the movable block moves to the right in fig. 1) along the telescopic slot 84, so that the elastic force of the elastic limiting mechanism 6 is reduced, the thrust required by the rotation of the movable guide plate in the sewing process of the corresponding cloth 12 is met, and the cloth 12 is placed to be excessively pressed against the fixed guide plate 4.
