[0030] The following will be combined with the drawings in this embodiment of the present invention to clearly and completely describe the technical solution in this embodiment of the present invention. Obviously, the embodiment described is only one embodiment of the present invention, not all embodiments of the present invention. Based on this embodiment of the present invention, all other embodiments of the present invention obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this utility model.

[0031] Example 1:

[0032] See also Figures 1 to 2 An embodiment of the utility model provides a sewing mechanism for a flap sewing tape, comprising a frame 1 and a sewing machine head 2 mounted on the frame 1, a sewing table 3 mounted below the sewing machine head 2, and a placement table 4 mounted at one end of the sewing table 3, a material moving mechanism 5 mounted on one side between the sewing table 3 and the placement table 4, the material moving mechanism 5 comprising a transverse driving module 51, a lifting driving module 52 mounted on the transverse driving module 51, and a pressing plate 53 mounted on the lifting driving module 52.

[0033] The transverse driving module 51 drives the lifting driving module 52 to move back and forth transversely, and the lifting driving module 52 drives the pressing plate 53 to move up and down.

[0034] The horizontal drive module 51 includes a rotary drive motor 511, a ball screw assembly 512 that is transmission-connected to the rotary drive motor 511, a first slide rail slider assembly 513 installed on one side of the ball screw assembly 512, and a vertical plate 514 installed on the ball screw assembly 512 and slidingly connected to the first slide rail slider assembly 513. The lifting drive module 52 is installed on the vertical plate 514.

[0035] The rotation drive motor 511 is a servo drive motor or a stepping drive motor.

[0036] A protective cover 517 is provided on the outside of the ball screw assembly 512. The protective cover 517 prevents sewing waste from entering the ball screw assembly 512 during the sewing process, thereby avoiding cleaning troubles and damaging the movement accuracy of the ball screw assembly 512.

[0037] Buffer blocks 518 are mounted on both ends of one side of the ball screw assembly 512 to match the vertical plate 514. The buffer blocks 518 prevent the pressure plate 53 from overshooting.

[0038] The lifting drive module 52 includes a lifting drive cylinder 521 installed on the horizontal drive module 51, a second slide rail slider assembly 522 installed on both sides of the lifting drive cylinder 521, and an L-shaped connecting plate 523 installed on the lifting drive cylinder 521 and slidingly connected to the second slide rail slider assembly 522.

[0039] An inverted L-shaped connecting plate 524 is installed at the bottom end of the L-shaped connecting plate 523, and the pressing plate 53 is installed on the inverted L-shaped connecting plate 524. Through the L-shaped connecting plate 523 and the inverted L-shaped connecting plate 524, the connection distance of the pressing plate 53 can be made farther, making it easier to transfer large and distant materials.

[0040] The operating principle of the sewing mechanism of a flap sewing tape in an embodiment of the present utility model is as follows:

[0041] S1: The flap and sewing tape are placed manually or automatically on the sewing table 3, and then the material transfer mechanism 5 transfers them. The transverse drive module 51 drives the lifting drive module 52 to the top of the sewing table 3, and the lifting drive module 52 drives the pressing plate 53 to press down the flap and sewing tape.

[0042] S2; Since the sewing table 3 and the placement table 4 are smooth metal plate table, so the pressure plate 53 can be pressed by the lateral drive module 51 and directly transferred to the sewing table 3;

[0043] S3: When the pressing plate 53 is in place, the sewing machine head 2 automatically executes the sewing program to sew the folding piece and the sewing tape.

[0044] Example 2:

[0045] See also Figures 3 to 5 An embodiment of the present invention provides a sewing and unloading device for a flap sewing tape, comprising a sewing mechanism for a flap sewing tape as described in Example 1, a sewing mechanism for a flap sewing tape having a unloading mechanism 6 installed on one side of a sewing table 3, the unloading mechanism 6 comprising a material taking component 61 installed on one side of the sewing table 3 and a material storage rack 62 installed on one side of the material taking component 61.

[0046] The material picking assembly 61 includes a hinge support 612, a pushing cylinder 611, a transmission rocker arm 613 and a material picking rocker arm 614. The hinge support 612 and the pushing cylinder 611 are respectively mounted on the frame 1. One end of the transmission rocker arm 613 is mounted on the pushing cylinder 611, and one side of the transmission rocker arm 613 is mounted on the hinge support 612. The material picking rocker arm 614 is mounted on the other end of the transmission rocker arm 613. The material storage rack 62 includes a fixed seat 621 mounted on the frame 1 and a hanging material bend 622 mounted on the fixed seat 621.

[0047] The operating principle of the sewing mechanism of a flap sewing tape in an embodiment of the present utility model is as follows:

[0048] Steps S1-S3 are similar to the operating principles of the sewing mechanism of the flap sewing tape in Example 1;

[0049] S4: When the sewing machine head 2 has finished sewing, the cylinder 611 is pushed to retract, causing one end of the transmission rocker 613 to rotate upward. At the same time, the transmission rocker 613 is restricted by the hinge support 612, causing the other end of the transmission rocker 613 to swing downward, thereby causing the material taking rocker 614 to swing downward, pulling the sewing tape and the flap onto the material hanging elbow 622 of the material storage rack 62;

[0050] S5: Conversely, the cylinder 611 is pushed out to reset, and the material-taking swing rod 614 swings upward and rotates. During this process, the sewing tape and the flap leave the material-taking swing rod 614 and are hung on the material-hanging elbow 622.

[0051] The advantages of the sewing mechanism of the flap sewing tape in the embodiment of the present invention are: fully automatic material transfer, sewing and cutting of the sewing tape and the flap are realized, thereby improving the degree of automation, effectively improving the sewing and sewing cutting efficiency, and greatly reducing the labor intensity of workers.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
