[0035] The working principle of the utility model is as follows:

[0036] The fabric to be folded is pushed in from the front side of the operation panel 1 through the conveying device until one end of the fabric is located above the hollow rectangular rod 408. At this time, the negative pressure air pump 405 is started, and the negative pressure air pump 405 generates suction to make the hollow rectangular rod 408 absorb the fabric through the air hole 407. At this time, the servo motor 406 drives the hollow rectangular rod 408 to flip through the transmission rod 410 until the hollow rectangular rod 408 folds and presses the fabric. At this time, the cylinder 2 413 pushes the folding strip 412 to move and tighten the fabric until it moves above the inclined bottom strip 402. At this time, the folding of the fabric is completed and a crease is formed;

[0037] The cylinder 301 pushes the U-shaped bar 303 forward until the bottom of the heating block 305 contacts the fabric and stops. At this time, the driving motor 306 drives the threaded rod 307 to rotate through the output shaft. The threaded rod 307 rotates the two heating blocks 305 to move from the middle to both sides, and the wrinkles of the fabric at the crease are smoothed while the fabric is hot-pressed until the heating block 305 leaves the folded fabric. At this time, the folding of the fabric is completed, the folded fabric is removed, and the sewing operation is carried out.
