In the following embodiments, the definitions of each direction are as follows: the extending direction of the X-axis is defined as the left-right direction, the extending direction of the Y-axis is defined as the front-rear direction, the extending direction of the Z-axis is defined as the up-down direction, and the front direction is defined as the sleeve direction. The fork sewing unit faces in the direction of the operator.

The present application provides a material transfer mechanism, which is mainly used in sleeve fork sewing equipment. As shown in Figures 1 to 4, the material transfer mechanism includes an outer binder 1 and an inner binder 2 installed on the outer binder 1, and the outer binder 1 can be used in the hemming mechanism and the sleeve fork sewing equipment. Moving between the sewing heads, both the lower end of the outer binder plate 1 and the lower end of the inner binder plate 2 have a binder surface for contacting with the cut pieces, and the outer binder plate 1 is provided with a storage space through up and down. Cavity 101, the inner binder plate 2 is placed in the receiving cavity 101, and a needle movement gap 3 is formed between it and the outer binder plate 1, and the needle movement gap 3 allows the pieces pressed by the material transfer mechanism to be exposed , and allowing the needles 36 on the sewing head to pass through, the inner hold-down plate 2 can move forward away from the receiving cavity 101 and move upward away from the cutting piece. In this embodiment, the width of the needle movement gap 3 is 2.2mm-2.5mm.

In the initial state, the material transfer mechanism is far away from the hemming mechanism of the sleeve fork sewing equipment. After the small piece is folded by the hemming mechanism and the large piece is placed above the small piece, the material transfer mechanism moves to the upper side of the large piece, and the outer pressure plate 1 drives the inner pressure plate 2 Press down, and then press the cutting pieces on the platen of the sleeve fork sewing equipment, and the inner pressing plate 2 is mainly used for pressing and sticking on the large cutting piece on the upper side of the small cutting piece, and the outer pressing plate 1 is mainly used for Because it is pressed on the large cut piece on the peripheral side of the small cut piece, the contact area between the outer pressing plate 1 and the big cut piece is relatively large. Afterwards, the material transfer mechanism moves to the sewing head, and then transfers the large and small pieces to the sewing head together; during this process, the small pieces are always in a tight state without wrinkles. Afterwards, the material transfer mechanism presses against the cutting piece and moves relative to the machine needle 36 on the sewing head, so that the machine needle 36 moves in the needle movement gap 3 to form the sleeve cross stitch 38; specifically, as shown in Figure 8a As shown, the needle movement start point 301 and the needle movement turning point 302 are set at the needle movement gap 3, and the needle 36 starts to sew large and small pieces at the needle movement start point 301, and then the material transfer mechanism presses against the cut piece. The piece moves relative to the needle 36, so that the needle 36 moves in one direction along the needle movement gap 3; , then the material shifting mechanism needs to move along the left and right direction to form a section of stitches extending left and right. , so that when the material shifting mechanism presses against the cut piece and moves in the left and right direction, the inner hold-down plate 2 will not collide with the needle 36, and then the rear end of the inner hold-down plate 2 moves downward to press and stick on the cut piece , and finally the material shifting mechanism presses against the cut piece and moves in the left and right directions, finally forming the sleeve cross stitch 38, as shown in Figure 8c. After the sewing finishes, the inner hold-down plate 2 resets. Therefore, the material transfer mechanism involved in this application has the functions of avoiding the wrinkles of the small pieces and driving the movement of the large pieces during the process of transferring the pieces, and the process of sewing the pieces with the needle 36 to form the sleeve cross stitch 38 Among them, the inner binder 2 and the outer binder 1 are always pressed against the cut pieces, which finally greatly guarantees the aesthetics of the stitches of the sleeve cuffs, making this application very suitable for sewing cuffs.
