The application provides a move material mechanism, mainly used sleeve vent makes up equipment. As shown in fig. 1 to 4, the material moving mechanism includes an outer material pressing plate 1 and an inner material pressing plate 2 mounted on the outer material pressing plate 1, the outer material pressing plate 1 can move between a hemming mechanism and a sewing head of the sleeve vent sewing device, the lower end of the outer material pressing plate 1 and the lower end of the inner material pressing plate 2 both have a material pressing surface for contacting with the cut pieces, an accommodating cavity 101 which is penetrated up and down is arranged in the outer material pressing plate 1, the inner material pressing plate 2 is arranged in the accommodating cavity 101 and forms a needle passing gap 3 with the outer material pressing plate 1, the needle passing gap 3 allows the cut pieces pressed by the material moving mechanism to be exposed and allows a needle 36 on the sewing head to pass through, and the inner material pressing plate 2 can move forward in a direction away from the accommodating cavity 101 and move upward in a direction away from the cut pieces. In this embodiment, the width of the stitch gap 3 is 2.2mm to 2.5 mm.

In the initial state, the material moving mechanism is far away from the edge folding mechanism of the sleeve fork sewing equipment. When the small-size piece by hem mechanism hem good, and place the top of small-size piece with big cut-size piece after, move material mechanism and remove the top side to big cut-size piece, and outer die plate 1 drives interior die plate 2 and pushes down, and then press the cut-size piece and paste on the platen of oversleeve sewing equipment, and, interior die plate 2 mainly used presses and pastes on the big cut-size piece of small-size piece top side, outer die plate 1 mainly used presses and pastes on the big cut-size piece of small-size piece periphery side, so the area of contact between outer die plate 1 and the big cut-size piece is great. Then, the material moving mechanism moves to the sewing head, and then the large cut piece and the small cut piece are moved to the sewing head together; in the process, the small cut pieces are always in a tight state, and no folds occur. Then, the material moving mechanism presses the cut pieces to move relative to the needle 36 on the sewing head, so that the needle 36 moves in the needle moving gap 3 to form an arm hole stitch 38; specifically, as shown in fig. 8a, a needle moving starting point 301 and a needle moving turning point 302 are arranged at the needle moving gap 3, the needle 36 starts to sew a large cut piece and a small cut piece at the needle moving starting point 301, and then the material moving mechanism presses the cut pieces to move relative to the needle 36, so that the needle 36 moves in one direction along the needle moving gap 3; as shown in fig. 8b, when the material moving mechanism presses against the cut piece to move and the needle 36 is located at the needle walking turning point 302, the material moving mechanism needs to move in the left-right direction to form a section of stitch extending left and right, at this time, at least the rear end of the inner pressing plate 2 moves upward and is separated from the cut piece, then the inner pressing plate 2 moves forward, so that the inner pressing plate 2 does not collide with the needle 36 when the material moving mechanism presses against the cut piece to move in the left-right direction, then the rear end of the inner pressing plate 2 moves downward and presses against the upper side of the cut piece, and finally the material moving mechanism presses against the cut piece to move in the left-right direction to finally form the sleeve fork stitch 38, as shown in fig. 8 c. After sewing, the inner pressing plate 2 is reset. Consequently, the in-process of cutting-parts is being transferred to the material moving mechanism that this application relates to has the effect of avoiding little cutting-parts fold and drive big cutting-parts removal concurrently to make the cutting-parts at eedle 36 and form the in-process of sleeve vent stitch 38, press flitch 2 and outer pressure flitch 1 to press the cutting-parts all the time, finally greatly guaranteed the pleasing to the eye degree of sleeve vent stitch, make this application be applicable to very much and make up the sleeve vent.
