Example 1

Referring to fig. 1, 2, 3 and 10, a hemming mechanism for an annular skirt machine, located between a sewing table and a driving mechanism, includes: the mounting seat 1 is mounted on the expansion mechanism of the annular lower pendulum machine, and the mounting seat 1 is provided with a mounting boss 102; a guide plate 2 mounted on the mount 1; the baffle plate 3 is arranged on the mounting seat 1 and is positioned at the feeding end of the guide plate 2; a first driving assembly 4 mounted at one side of the mounting boss 102; a second driving assembly 5 mounted on the other side of the mounting boss 102; a first supporting plate 6 mounted on the first driving assembly 4 and above the guide plate 2 for supporting the hem of the sewing cloth hem; and a second supporting plate 7 mounted on the second driving assembly 5 and above the guide plate 2 for supporting the hem of the sewing cloth hem.

The flanging mechanism for the annular lower hem machine is arranged on the expansion mechanism, can be far away from or close to the sewing table along with the expansion mechanism, has a more compact structure by optimizing the driving mechanism, shortens the distance between the sewing table and the driving mechanism, and can sew the small-size upper garment.

Referring to fig. 1 and 4, the guide plate 2 includes a guide portion 201 and a flange portion 202, the flange portion 202 is disposed at one end of the guide portion 201, the guide portion 201 has an arc edge extending from the flange portion 202, and the cloth is gradually folded into a folded edge when passing through the arc edge. To further facilitate hemming, in this embodiment, the guiding portion 201 is disposed obliquely, and the oblique direction forms a horizontal angle with the advancing direction of the sewing cloth. In addition, two adjusting grooves are provided on the guide portion 201, the direction of the adjusting grooves is perpendicular to the advancing direction of the sewing cloth, the guide plate 2 can move back and forth by the adjusting grooves, and the distance between the flange portion 202 and the baffle 3 (the width of the folded edge is also changed).

The baffle 3 is mounted on the mounting base 1 and is located at the feed end of the guide plate 2, i.e. near the flange 202. The end of the baffle 3 is spaced from the flange 202. In the example of the coat, when the hem of the coat is abutted against the flange 202, the flange 202 is not supported by the baffle 3, so that the hem of the coat is partially sagged under the action of gravity. The sewing cloth is driven by the driving mechanism to form a 'turn' action, and the drooping part moves along with the sewing cloth, and the hemming is gradually formed through the guide part 201 in the moving process.

After all the hems of the lower hem are folded, the sewing is started, and after the sewing is finished, the first support plate 6 and the second support plate 7 are sequentially retracted under the drive of the first driving assembly 4 and the second driving assembly 5, so that the hems which are not sewn are sewn through the sewing table.

The expansion mechanism and the sewing table have a certain length, and the hem can displace due to vibration in the sewing process to influence the final sewing effect. Thus, a first support plate 6 and a second support plate 7 are provided. Because the part with a certain length, which is not sewn and is provided with the front hem, between the expansion mechanism and the sewing table is smooth, the hem is additionally provided with a stitch after sewing, so that the hem cannot perform a turning motion, and therefore, in order to ensure that the unsewn hem is sewn through the sewing table, the first support plate 6 and the second support plate 7 retract in sequence, and the hem can be supported while the turning motion of the hem is ensured.

Referring to fig. 5, the mounting base 1 includes a mounting body 101 and a mounting boss 102.
