[0020] As Figure 1 and Figure 2As shown in the figure, the needle-punching material-taking mechanism of the present utility model includes a mounting base 1 and two needle-punching assemblies fixedly connected to the mounting base 1. The two needle-punching assemblies drive the needle 7 to pass through the through slot 1c on the mounting base 1, and use the part of the needle 7 exposed from the bottom surface of the mounting base 1 to staggeredly pierce the sewing material and grab the sewing material.

[0021] The mounting base 1 is composed of a material-grabbing flat plate 1a at the bottom and two inclined mounting plates 1b. The material-grabbing flat plate 1a is provided with a plurality of parallel through slots 1c for the needle 7 to pass through. The needle 7 staggeredly pierces the sewing material, so that the sewing material fits the lower surface of the material-grabbing flat plate 1a to fix the sewing material. The left side plate 10 and the right side plate 9 of the needle-punching assembly are respectively fixedly connected to the left and right sides of the mounting plate 1b on the mounting base 1.

[0022] As Figure 3 shown in the figure, the needle-punching assembly includes a micro cylinder 2, a cylinder bracket 3, a connecting plate 5, a bolt 6, a needle 7, a needle mounting bracket 8, a right side plate 9, and a left side plate 10. The cylinder bracket 3 obliquely mounts the micro cylinder 2, and the long screw 4 passes through the cylinder bracket 3 to obliquely mount it on the right side plate 9. The connecting plate 5 is in an "L" shape, with one end connected to the driving link of the micro cylinder 2 and the other end connected to the first needle slot plate 8c of the needle mounting bracket 8.

[0023] The driving link of the micro cylinder 2 drives the connecting plate 5 to move, the connecting plate 5 drives the needle mounting bracket 8 to move, and the needle 7 mounted on the needle mounting bracket 8 passes through the through slot 1c on the mounting base 1.

[0024] The needle mounting bracket 8 includes an upper cover plate 8a, a lower cover plate 8b, a first needle slot plate 8c, a second needle slot plate 8e, and a needle slot 8f. The left and right sides of the first needle slot plate 8c have two protruding parts 8d. The inner sides of the right side plate 9 and the left side plate 10 are provided with two inclined grooves 11. The protruding parts 8d of the first needle slot plate 8c just engage with the grooves 11 on the inner sides of the left side plate 10 and the right side plate 9, and the first needle slot plate 8c moves obliquely along the grooves 11, and the needle mounting bracket 8 moves obliquely along the grooves 11.

[0025] The lower surface of the first needle slot plate 8c is provided with a plurality of parallel needle slots 8f, and a plurality of needles 7 are installed in the corresponding needle slots 8f. The second needle slot plate 8e is installed on the first needle slot plate 8c. The upper surface of the second needle slot plate 8e is provided with the same number of needle slots 8f as the first needle slot plate 8c. The needle slots 8f on the first needle slot plate 8c correspond to the needle slots 8f on the second needle slot plate 8e one by one. The upper cover plate 8a and the lower cover plate 8b respectively fix the needle 7 in the corresponding needle slot 8f, and the needles 7 mounted on the same needle mounting bracket point in the same direction.

[0026] Two needle-piercing components are installed on the mounting base 1 facing each other, and the moving directions of the needle-passing holes 7 on the two needle-piercing components are mirror-symmetrical. The needle-passing holes 7 on the two needle-piercing components jointly pass through the corresponding through slots 1c on the mounting base 1, and the number of through slots 1c on the mounting base 1 should be twice the number of needle-passing slots 8f on the first needle slot plate 8c.

[0027] In this embodiment, the first needle slot plate 8c and the second needle slot plate 8e are respectively provided with three needle-passing slots 8f, and the number of through slots 1c on the mounting base 1 is six. Three needle-passing holes 7 are installed on both the first needle slot plate 8c and the second needle slot plate 8e. The three needle-passing holes 7 on the right needle-piercing component respectively pass through the odd-numbered through slots 1c on the mounting base 1, and the three needle-passing holes 7 on the left needle-piercing component respectively pass through the even-numbered through slots 1c on the mounting base 1. The needle-passing holes 7 on the two needle-piercing components are staggered with each other to attach the sewing material to the bottom surface of the mounting base 1 and grab the sewing material.

[0028] The head end of the bolt 6 is rotatably installed on the connecting plate 5, and the screw rod of the bolt 6 passes through the connecting plate 5 and extends downward. When the driving link of the micro cylinder 2 drives the connecting plate 5 to move obliquely downward, the connecting plate 5 drives the needle-passing mounting bracket 8 to move obliquely downward. At the same time, the lower end of the bolt 6 on the connecting plate 5 moves obliquely downward until the lower end of the screw rod of the bolt 6 abuts against the long screw 4 passing through the cylinder bracket 3, and then the needle-passing mounting bracket 8 stops moving, and the needle-passing holes 7 installed on the needle-passing mounting bracket stop moving. By adjusting the bolt 6, the moving stroke of the driving link of the micro cylinder 2 is controlled, so as to adjust the exposed length of the needle-passing holes 7 driven by the needle-passing mounting bracket 8 through the through slots 1c to adapt to the needle piercing of sewing materials with different characteristics and thicknesses.

[0029] The best embodiment of the present utility model has been illustrated, and various changes or modifications made by those of ordinary skill in the art will not depart from the scope of the present utility model.
