DETAILED DESCRIPTION

[0020] The following is in conjunction with the appendix Figures 1-7 The specific embodiments of this utility model will be described in further detail.

[0021] In the first embodiment, the technical solution is to lay the fabric flat on the plate 1, fold the side of the fabric that needs to be hemmed and align it with the pressure plate 15, and then energize the electromagnet 20 in the upper mounting groove. After being energized, the electromagnet 20 will generate magnetism and create attraction between itself and the armature 19 on its corresponding side. Since the armature 19 is fixed in the lower mounting groove and cannot move, the electromagnet 20 will move closer to the armature 19 under the action of attraction. Consequently, the pressure plate 15, which is vertically sliding and engaged with the vertical shaft 14, will also move closer to the plate 1 along with the electromagnet 20 and press the side of the fabric that needs to be hemmed. At this time, the spring 18, which is fixedly connected between the pressure plate 15 and the baffle 17, is in a stretched state. After the fabric is pressed down by the pressure plate 15, adjusting the needle part 4 of the automatic sewing machine allows for sewing. Then, the motor 12 of the automatic sewing machine and drive unit is started. The drive unit moves the automatic sewing machine laterally to sew and hem the fabric. Because the fabric is pressed down by the pressure plate 15, no manual intervention is needed to pull or guide the fabric, ensuring safety and efficiency. When it is necessary to release the pressure on the fabric, simply de-energize the electromagnet 20. De-energizing the electromagnet 20 will cause it to lose its magnetism and no longer attract the armature 19. At this time, under the self-restoring action of the spring 18, the spring 18 will contract and drive the pressure plate 15 to move upwards along the vertical axis 14, releasing the pressure on the fabric.

[0022] Specifically, the front flange 10 of the lower body 3 of the automatic sewing machine is laterally slidably engaged with the side groove 9 on the front side wall of the through groove 6; the rear part of the lower body 3 passes through the connecting cavity 8 and is laterally slidably engaged with the connecting cavity 8; the needle plate 5 on the lower body 3 is laterally slidably engaged with the slide groove 7, which ensures the sliding support of the slide assembly for the automatic sewing machine and ensures that the automatic sewing machine can run normally along the slide assembly under the drive of the drive device.

[0023] After pressing the fabric and adjusting the sewing machine, start the automatic sewing machine and the motor 12 of the drive unit. The motor 12 will drive the reciprocating screw 11 to rotate. Since the automatic sewing machine is threadedly engaged with the reciprocating screw 11 through the threaded hole 13, the rotation of the reciprocating screw 11 will drive the automatic sewing machine to move laterally along the slide assembly. During this lateral movement, the automatic sewing machine will complete the overlocking of the fabric. The channel 16 on the pressure plate 15 corresponds to the needle punch 4 on the upper body 2, ensuring that the needle punch 4 can work normally without being affected by the pressure plate 15. The provided support legs 21 are used to support the flat plate 1.
