In the present embodiment, the top plate 6 is attached to the first middle plate 2.
The principle of use of the utility model is described below with reference to fig. 5, in order to understand the utility model:
first, a pocket fabric 100 is placed on the front end of the top plate 6, and then a feeding mechanism (not shown) above the top plate 6 pushes the pocket fabric 100 to move backward. In the moving process of the pocket cloth 100, the end part of the pocket cloth needing to be curled enters the curling groove and enters between the first middle plate 2 and the bottom plate 1 through the guiding of the curling plate 4 to form a first curled edge; then, when the pocket cloth 100 continues to move, the pocket cloth 100 enters the guide arc-shaped groove 53 through the end of the first curled edge, and gradually enters between the second middle plate 3 and the top plate 6 under the guide of the guide arc-shaped groove 53 to form a second curled edge, and then the pocket cloth 100 contacts with the second guide plate 52 after continuing to move and is shaped; at this time, the shape of the pocket fabric 100 is as shown in fig. 5, and a first hem portion 101 and a second hem portion 102 are formed; finally, the sewing machine head (not shown) can be used for sewing the specific position of the pocket cloth. When the position of the guide plate 5 needs to be adjusted, the position is directly controlled on an industrial personal computer, and the adjustment data can also be set on the industrial personal computer; during the adjustment process, the motor 71 drives the screw 72 to rotate, so as to drive the slider 73 to move, and the first guide plate 51 and the second guide plate 52 are driven by the first connecting strip 74 and the second connecting strip 75 to move synchronously, so that the distance between the guide plate 5 and the hemming plate 4 is changed, for example, is increased or decreased, it is not difficult to imagine that if the distance between the guide plate 5 and the hemming plate 4 is increased, the width between the left and right sides of the first hemming portion 101 is increased and the width between the left and right sides of the second hemming portion 102 is decreased, compared with the pocket cloth 100 shown in fig. 5, after the pocket cloth 100 is hemmed twice, and similarly, if the distance between the guide plate 5 and the hemming plate 4 is decreased, the width between the left and right sides of the first hemming portion 101 is decreased compared with the pocket cloth 100 shown in fig. 5, the width between the left side and the right side of the second crimping portion 102 will be increased, and different manufacturing requirements can be met by adjusting the width of the first crimping portion 101 and the second crimping portion 102.
The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
