Description

Technical Field

[0001] The utility model relates to the technical field of cloth weaving equipment, in particular to a multi-layer cloth edge feeding device for clothes production. Background Art

[0002] In an automated production line, some products can be transported by vacuum adsorption, which is highly efficient and low in cost. However, breathable and non-steel products cannot be transported by vacuum adsorption, which leads to a needle-piercing gripper device, such as the Chinese utility model patent with announcement number CN208179564U, which records a needle-piercing gripper device, in which the air needle is driven through the oblique hole by the first and second air cylinders respectively, and the breathable and non-steel products are pierced by the exposed part of the first and second air needles from the bottom of the air needle block to fix the products, thereby transporting the products to other locations, which is highly efficient, low in cost and has a better use effect. When it needs to be put down, the air needle is retracted by the first and second air cylinders, so that the fabric and substrate fall down.

[0003] However, the penetration depth and angle of the air needles on both sides are limited by the shape of the air needle block. When encountering the clamping of multi-layer fabrics, due to the large thickness of the multi-layer fabrics and the shallow penetration depth of the air needles on both sides, the bottom layer of the multi-layer fabrics cannot be grasped, resulting in poor feeding effect of the gripper device for the multi-layer fabrics. Therefore, in view of these current situations, it is urgent to develop a multi-layer fabric edge feeding device for clothing production to meet the needs of actual use. Utility Model Content

The piston rod of the pushing cylinder is connected to one end of the air needle fixing block and drives the air needle fixing block to move.

[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0020] See also Figure 1-5 A multi-layer cloth edge feeding device for clothing production is specifically implemented, comprising a moving module 1 and an air needle gripper 2, the air needle gripper 2 and the moving module 1 are connected by a connecting slider 3, the air needle gripper 2 can be located on one side of the moving module 1 for horizontal movement, the air needle gripper 2 comprises an air needle block 21 and a first air needle 24 structure and a second air needle 24 structure which are symmetrically arranged, the two side walls of the air needle block 21 are inwardly inclined interlaced inclined surfaces 211, the top of the interlaced inclined surfaces 211 is provided with a downwardly protruding rotating protrusion 2112, the first air needle 24 structure and the second air needle 24 structure are provided with a rotating support 222 matching the rotating protrusion 2112 on one side close to the rotating protrusion 2112, the first air needle 24 structure and the second air needle 24 structure are rotatably connected to the rotating protrusion 2112 through the rotating support 222.

[0021] A downwardly protruding rotating protrusion 2112 is provided in the interlaced inclined surfaces 211 on both sides of the air needle block 21, wherein the first air needle 24 structure and the second air needle 24 structure can be rotatably connected through a rotating support 222 matching the rotating protrusion 2112. In the case of multi-layer fabrics, the angle between the first air needle 24 structure and the second air needle 24 structure and the air needle block 21 can be adjusted by adjusting the rotating protrusion 2112 and the rotating support 222, thereby reducing the interlaced angle between the first air needle 24 structure and the second air needle 24 structure, thereby increasing the insertion depth of the air needle 24, and ensuring that the air needle 24 can grab the bottom layer of the multi-layer fabric.

[0022] Specific as Figure 4 and Figure 5 As shown, the first air needle 24 structure and the second air needle 24 structure both include a pushing cylinder 22, an air needle fixing block 23 and several air needles 24. The air needles 24 are multiple metal needles arranged in parallel and at intervals. The pushing cylinder 22 is installed on the air needle block 21. The air needle fixing block 23 is an L-shaped block. The piston rod 221 of the pushing cylinder 22 is connected to one end of the air needle fixing block 23 and drives the air needle fixing block 23 to move. The other end of the air needle fixing block 23 is connected to the air needle 24.

[0023] Among them, air-avoiding slots 2111 are opened on both sides of the bottom of the air needle block 21, and the end of the air needle 24 away from the air needle fixing block 23 is embedded in the air-avoiding slot 2111, and the bottom end of the air needle 24 can be extended to the bottom of the air needle block 21 by pushing the cylinder 22. When the rotating protrusion 2112 and the rotating support 222 are adjusted to adjust the angle between the first air needle 24 structure and the second air needle 24 structure and the air needle block 21, the air needle 24 can move inside the air-avoiding slot 2111, so that the movement trajectory of the air needle 24 and the air needle block 21 form a complementary interference effect.

[0024] Specific as Figure 2 As shown, a guide rail 11 is provided on the top of the movable module 1, and the air needle gripper 2 is slidably arranged in the middle of the guide rail 11 through a connecting slider 3.

The other end of the connecting slider 3 is a connecting portion 32, and one end surface of the air needle block 21 is fixedly connected to the connecting portion 32.

[0026] The working process of a multi-layer edge feeding device for clothing production is as follows: by measuring the thickness of the multi-layer edge material, the angle between the first air needle 24 structure and the second air needle 24 structure and the air needle block 21 is adjusted by correspondingly rotating the rotating protrusion 2112 and the rotating support 222, and the staggered angle between the first air needle 24 structure and the second air needle 24 structure is reduced, so that the insertion depth of the air needle 24 is increased, and it is ensured that the air needle 24 can grab the bottom layer of the multi-layer fabric;

[0027] Then, by pushing the piston rod 221 of the cylinder 22, the air needle fixing block 23 is driven to move downward, and the air needle 24 at the bottom of the air needle fixing block 23 can penetrate the interlaced inclined surface 211 and extend to the bottom of the air needle block 21, so as to interlace the multiple layers of cloth alternately. At the same time, the synchronous wheel 13 is driven to rotate by the motor 14, and the synchronous belt 12 can move horizontally by engaging with the synchronous wheel 13. At the same time, the air needle gripper 2 can move by following the movement of the synchronous belt 12 by connecting the slider 3, so as to drive the multiple layers of cloth to be fed.
