Therefore, without technical substantive significance, any modification of structure, change of proportional relationship or adjustment of size should still fall within the scope disclosed in the present invention without affecting the effect that the present invention can produce and the purpose that can be achieved. within the scope of technical content. At the same time, the terms such as "up", "down", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit the present invention. The practicable scope and the change or adjustment of the relative relationship thereof shall also be regarded as the practicable scope of the present invention without substantially changing the technical content.

In the following embodiments, each direction is defined 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 the sleeve Fork stitching equipment faces the direction of the operator.

The present application provides a material transfer mechanism, which is mainly used in a sleeve and fork sewing equipment. As shown in Fig. 1 to Fig. 4, the material transfer mechanism includes an outer pressing plate 1 and an inner pressing plate 2 installed on the outer pressing plate 1. The outer pressing plate 1 can be used in the hemming mechanism and the hemming mechanism of the sleeve and fork sewing equipment. Moving between the sewing heads, the lower end of the outer pressing plate 1 and the lower end of the inner pressing plate 2 both have a pressing surface for contacting with the cutting piece, and the outer pressing plate 1 is provided with an upper and lower through-hole receiving Cavity 101, the inner pressing plate 2 is arranged in the receiving cavity 101, and a needle moving gap 3 is formed between the inner pressing plate 2 and the outer pressing plate 1, and the needle moving gap 3 allows the cut pieces pressed by the feeding mechanism to be exposed. , and allow the needle 36 on the sewing head to pass through, the inner holding plate 2 can move forward in the direction away from the receiving cavity 101 and move upward in the direction away from the cutting piece. In this embodiment, the width of the needle moving gap 3 is 2.2 mm˜2.5 mm.

In the initial state, the material transfer mechanism is far away from the hemming mechanism of the sleeve and fork sewing equipment. When the small pieces are folded by the hemming mechanism and the large pieces are placed above the small pieces, the moving mechanism moves to the upper side of the large pieces, and the outer pressing plate 1 drives the inner pressing plate 2 Press down, and then press the cutting piece on the table board of the sleeve and fork sewing equipment, and the inner pressing material 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 material plate 1 is mainly used for Since the large cutting piece is pressed against the outer peripheral side of the small cutting piece, the contact area between the outer pressing plate 1 and the large cutting piece is relatively large. After that, the feeding mechanism moves to the sewing head, and then transfers the large piece and the small piece to the sewing head together; during this process, the small piece is always in a taut state without wrinkles. Afterwards, the material transfer mechanism moves relative to the needle 36 on the sewing head by pressing against the cutting piece, so that the needle 36 moves in the needle-moving gap 3 to form the sleeve fork stitch 38; specifically, as shown in FIG. 8a It is shown that the needle movement starting point 301 and the needle movement turning point 302 are set at the needle movement gap 3. The needle 36 starts to sew large pieces and small pieces at the needle movement starting point 301, and then the feeding mechanism is pressed against the cutting piece. The sheet moves relative to the needle 36, so that the needle 36 moves in one direction along the needle-moving gap 3; as shown in FIG. At this time, the moving mechanism needs to move in the left and right directions to form a stitch extending left and right. At this time, at least the rear end of the inner pressing plate 2 moves upwards and separates from the cutting piece, and then the inner pressing plate 2 moves forward. , so that when the material-moving mechanism moves in the left-right direction against the cutting piece, the inner pressure plate 2 will not collide with the needle 36, and then the rear end of the inner pressure plate 2 moves downward and is pressed against the top of the cutting piece. , and finally the material-moving mechanism moves in the left-right direction against the cut piece, and finally forms the sleeve fork stitch 38, as shown in Figure 8c. After the sewing is completed, the inner holding plate 2 is reset. Therefore, in the process of transferring the cut pieces, the material transfer mechanism involved in the present application has the functions of preventing the wrinkle of the small pieces and driving the large pieces to move, and the process of sewing the cut pieces with the machine needle 36 to form the sleeve fork stitches 38 In the middle, the inner pressing plate 2 and the outer pressing plate 1 are always pressed against the cut piece, which ultimately greatly ensures the aesthetics of the stitch of the sleeve and fork, making the present application very suitable for the sewing of the sleeve and fork. The shape of the outer contour of the inner blanking plate 2 and the shape of the needle-moving gap 3 formed between the inner blanking plate 2 and the outer blanking plate 1 are determined according to the required sleeve fork stitches.
