Moreover, when the counter-pulling spring 72 is in a natural state, the two inner pressing plate adapter seats 14 are correspondingly abutted against the two adapter seat positioning blocks one by one; at this time, the spacing between the two inner platen adapters 14 is at a design minimum.

Referring to fig. 5 and 6, there are two spindle retainers 73, and the two spindle retainers 73 are correspondingly mounted on the two presser foot spindles 12 one by one; specifically, the rotating shaft retainer 73 is fixedly installed at one end of the presser foot rotating shaft 12 far away from the flattening screw 711, so that the rotating shaft retainer 73 can move along with the presser foot rotating shaft 12. Meanwhile, one end of the inner pressure plate push plate 74 is mounted on the inner pressure plate adapter 14 through a bolt, and the other end of the inner pressure plate push plate is connected with a sleeving ring 741; the sleeving ring 741 is sleeved on the presser foot rotating shaft 12, and the inner diameter of the sleeving ring 741 is larger than the diameter of the presser foot rotating shaft 12.

Referring to fig. 5 and 6, the position of the sleeving ring 741 is on a side of the rotating shaft retaining ring 73 facing the flattening screw 711, and when the distance between the two inner pressing plate adapters 14 is the minimum, there is a gap between the sleeving ring 741 and the rotating shaft retaining ring 73. Meanwhile, the distance between the sleeving ring 741 and the rotating shaft retainer ring 73 is smaller than the movement distance of the presser foot rotating shaft 12 driven by the rotating shaft stretching assembly 71; so that in the process that the presser foot rotating shaft 12 is driven to move in the direction away from the other presser foot rotating shaft 12, the rotating shaft retainer ring 73 gradually approaches and abuts against the sleeve joint ring 741 of the inner pressing plate push plate 74 along with the movement of the presser foot rotating shaft 12, and then drives the inner pressing plate push plate 74 to move together, thereby achieving the effect of increasing the distance between the two inner presser foot pressing rods 51.

The implementation principle of this application embodiment presser foot device does: the cloth material and the fly cloth material are placed on the bottom plate 2, and the presser foot rotating shaft 12 is driven to rotate by the outer presser bar pressing mechanism, so that the outer presser bar assembly 3 swings towards the bottom plate 2 to tightly support the cloth material.

Then, the flattening screw 711 in the flattening driving mechanism 7 is started to drive the two flattening sliders 713 to be away from each other, so that the two presser foot rotating shafts 12 are kept away from each other, and the two sets of outer presser bar assemblies 3 are driven to be away from each other, thereby realizing the effect of flattening the cloth of the clothes. At this time, the shaft retainer ring 73 gradually approaches the sleeve joint ring 741 of the inner pressing plate push plate 74 along with the movement of the presser foot shaft 12.

When the rotating shaft retainer ring 73 is abutted with the sleeving ring 741 of the inner pressing plate push plate 74, the inner pressing pin pressing mechanism drives the inner pressing rod assembly 5 to descend to tightly abut the front fly cloth. Then, the rotating shaft retainer ring 73 continues to move along with the presser foot rotating shaft 12, and the two groups of inner pressure rod assemblies 5 are driven to start to be away from each other by the abutting action between the rotating shaft retainer ring 73 and the sleeve joint ring 741 of the inner pressure plate push plate 74, so that the effect of flattening the placket front cloth is achieved.

In the whole flattening process, the cloth of the clothes is firstly flattened, then the cloth of the front fly is flattened, and finally the cloth of the front fly and the cloth of the clothes are flattened, so that the phenomenon that the cloth of the clothes and the cloth of the front fly are wrinkled to influence the flatness of the cloth of the clothes and the cloth of the front fly after subsequent sewing is effectively reduced.

On the contrary, the two sets of shaft stretching assemblies 71 respectively drive the presser foot shafts 12 to move along the mutually approaching direction, so as to directly drive the two sets of outer presser bar assemblies 3 to approach each other, and the two sets of inner presser bar assemblies 5 to approach each other under the elastic restoring force action of the counter-pulling springs 72.

After the sewing device sews the U-shaped stitch on the front fly cloth and the clothes cloth, if the front fly cloth needs to be turned over and a stitch is sewed along the turning edge of the front fly cloth, the outer side blow pipe 321 on one side needing to be turned over can be directly used for blowing the front fly cloth after the front fly inner pressing plate 52 is driven to be lifted, so that the effect of turning over the front fly cloth is achieved. After the sewing device is utilized to make stitches at the folded edge of the fly fabric, the folded side of the fly fabric can be blown and unfolded by using the inner side blowing pipe 521, so that the clothes fabric and the fly fabric can be cut by using the shearing device in the following process.

The embodiment of the application further discloses a front fly machine, which comprises the presser foot device, so that the front fly cloth and the clothes cloth can be flattened, and the condition that the clothes cloth and the front fly cloth are wrinkled to influence the flatness of the clothes cloth and the front fly cloth after subsequent sewing is effectively reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
