DETAILED DESCRIPTION

[0019] As shown in the accompanying drawings, an automatic cloth hemming device includes a frame 1 and a sewing machine head 2, wherein the frame 1 is provided with an automatic cloth hemming device, a cloth conveying device and a cloth pressing and conveying clamp assembly 12; the automatic cloth hemming device includes a motor 22, a cloth folding reversing device 3 and a cloth pressing assembly; the cloth folding reversing device 3 includes a toothed body 17 and a steel sheet 18. A telescopic cylinder 4 and a reversing cylinder 5 are respectively provided at both ends of the cloth folding reversing device 3 to achieve reversal; the cloth pressing assembly includes two side fixing seats 6, two side connecting arms 7, a pressing plate 8, a pressure bearing 9 and a cloth pressing cylinder 10, wherein the two side fixing seats 6 are fixed on the frame 1, one end of the two side connecting arms 7 is respectively fixed on the fixing seats 6, and the other end is connected to the pressing plate 8, and a reinforcing plate 16 is also provided between the two side connecting arms 7. The two ends of the pressure bearing 9 are respectively connected to the connecting arms 7 on both sides and fixed to the fixing seat 6. The cloth pressing cylinder 10 is provided with a support arm 11, which is matched and clamped with the pressure bearing 9. The pressure bearing 9 is pushed by the cloth pressing cylinder 10 to realize the pressing plate 8 to press the cloth, so that the cloth can be folded in one fold. The connection between the support arm 11 and the pressing plate 8 is provided with a slider 13 and a slider control motor. After the cloth is folded in one fold, the cloth is pushed into the cloth folding reversing device 3. Then, the cloth folding reversing device 3 is used to realize two folds; the folded cloth is conveyed to the sewing machine head 2 for sewing through the cloth conveying device and the cloth pressing and conveying clamp assembly 12.
