DETAILED DESCRIPTION

[0032] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, the specific implementation manners of the present application will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0034] In this paper, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0035] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] Referring to Figs. 1-4 A fine wire mesh braider is provided, a storage reel 1 is rotationally arranged for winding weft wires, the storage reel 1 has a gap 101; a wire moving member 2 is arranged eccentrically relative to the rotation axis of the storage reel 1, and revolves around the axis of the storage reel 1 and rotates, the wire moving member 2 has a claw portion 201 which is movable in the gap 101 for moving the weft wires.

[0037] In this embodiment, the storage reel 1 is used for winding weft wires, and can rotate, the rotation of the storage reel 1 enables the weft wires to be uniformly wound thereon without the need for additional complex guiding mechanisms. The gap 101 on the storage reel 1 is used to accommodate the claw portion 201 of the wire moving member 2, ensuring that the claw portion 201 can smoothly enter and exit the storage reel 1, and realizing the movement of the weft wires. The wire moving member 2 is arranged eccentrically relative to the rotation axis of the storage reel 1, which means that its center of rotation does not coincide with the axis of the storage reel 1. This eccentric arrangement enables the wire moving member 2 to revolve around the axis of the storage reel 1 while also rotating, and the claw portion 201 of the wire moving member 2 is designed to be freely movable in the gap 101 of the storage reel 1. When the wire moving member 2 revolves, the claw portion 201 will periodically enter and exit the gap 101, thereby moving the weft wires.

[0038] As a preferred, a large-diameter storage reel 1 is designed, so that the wound spiral is larger, the weft wires are not easy to bend, and the overall shape is well maintained. This not only facilitates subsequent processing, but also improves the winding quality, ensures the overall shape and stability of the weft wires, simplifies the mechanical structure, and reduces the maintenance cost. The weaving efficiency and quality are improved.

[0039] Further, the angular velocity of the self-rotation of the wire moving member 2 is the same as the angular velocity of the rotation of the storage reel 1.

[0040] In this embodiment, due to the same angular velocity, the claw portion 201 of the wire moving member 2 can freely enter and exit the gap 101 of the storage reel 1, and will not be stuck or collided due to the difference in angular velocity. This ensures that the claw portion 201 can accurately move the weft wires, realizing stable winding operation.

[0041] Further, the sun gear 3 is arranged coaxially with the storage reel 1; the planetary gear 4 is engaged with the sun gear 3 and revolves around the sun gear 3, and the wire moving member 2 is arranged on the planetary gear 4, the planetary gear 4 revolves and rotates, synchronously driving the wire moving member 2 to revolve around the axis of the storage reel 1 and rotate.

[0042] In this embodiment, the sun gear 3 is coaxial with the yarn storage frame 1, providing a basic connection for power transmission. The planetary gear 4 is engaged with the sun gear 3. Due to the gear transmission characteristics, the planetary gear 4 not only revolves around the sun gear 3, but also rotates due to the engagement relationship. The yarn moving piece 2 is installed on the planetary gear 4, and revolves and rotates around the axis of the yarn storage frame 1 synchronously with the revolution and rotation of the planetary gear 4, thereby driving the claw part 201 to move the weft yarn. By utilizing the high precision and stability of gear transmission, the complex revolution and rotation movement of the yarn moving piece 2 is achieved. Compared with other transmission modes, the structure is compact, the transmission ratio is accurate, the yarn moving action can be maintained stably for a long time, and the continuity of the weaving process is ensured.

[0043] Further, the number of teeth of the sun gear 3 is Z1, and the number of teeth of the planetary gear 4 is Z2.

[0044] In this embodiment, as a preferred example, the time for the planetary gear 4 to revolve around the sun gear 3 for one revolution is T, the rotation angular velocity of the yarn moving piece 2 is ω1, and the rotation angular velocity of the yarn storage frame 1 is ω2, wherein Z1 / Z2*360°=ω1T=ω2T, the number of teeth Z2 of the planetary gear 4 is greater than the number of teeth Z1 of the sun gear 3, so that the planetary gear 4 revolves for one revolution around the sun gear 3 while rotating less than one revolution. The effect is to make the rotation angular velocity of the yarn moving piece 2 the same as the rotation angular velocity of the yarn storage frame 1. For example, when Z1 / Z2=1 / 10, i.e. 1 / 10*360°=36°, the planetary gear 4 revolves for one revolution while rotating 36°, i.e. the yarn moving piece 2 revolves for one revolution while rotating 36°, and because the rotation angular velocity of the yarn moving piece 2 is the same as the rotation angular velocity of the yarn storage frame 1, the yarn storage frame 1 also rotates 36°. As a preferred example, the number of teeth can be matched to ensure the regularity of the movement of the yarn moving piece 2, and the cooperation of each revolution and rotation is accurate, so that the claw part 201 can grasp and release the weft yarn in a fixed mode, improve the precision of weft yarn transfer, make the position of the weft yarn supplied to the weaving area more accurate, and help to improve the fineness of the metal wire mesh weaving.

[0045] Further, the transmission cylinder 6 is rotationally arranged on the base frame 5, the planet carrier 7 is arranged at one end of the transmission cylinder 6, the arrangement direction of the planet carrier 7 is along the radial direction of the transmission cylinder 6, and the planetary gear 4 is rotationally arranged on the planet carrier 7. The rotation axis of the planetary gear 4 is parallel to the rotation axis of the transmission cylinder 6.

[0046] In this embodiment, the base frame 5 serves as the support structure of the entire device, the transmission cylinder 6 is rotatably installed on the base frame 5, the planet carrier 7 is installed radially on one end of the transmission cylinder 6, and the planetary gear 4 is rotatably arranged on the planet carrier 7, and the rotation axis is parallel to the rotation axis of the transmission cylinder 6. The planetary gear 4 is driven to rotate through gear meshing, and then the yarn shifting member 2 operates to realize the entire weft feeding process. Reasonable layout of components, radial arrangement of the planet carrier 7 provides stable support and suitable installation position for the planetary gear 4, and the transmission structure is clear in hierarchy, which is convenient for installation and debugging, and also helps to maintain stable power transmission during equipment operation, reduces vibration and component wear.

[0047] Further, the mounting table 8 is annular and rotatably arranged on the transmission cylinder 6 coaxially with the transmission cylinder 6, and the yarn storage rack 1 is arranged on the mounting table 8.

[0048] In this embodiment, the annular mounting table 8 is installed on the transmission cylinder 6 and rotatably arranged relative to the transmission cylinder 6. In general, the rotation angular velocity of the transmission cylinder 6 is greater than that of the mounting table 8, and the mounting table 8 can be driven by a gear assembly independently of the gear assembly driving the transmission cylinder 6. The mounting table 8 coaxially arranged with the transmission cylinder 6 can reduce the unbalanced force caused by eccentric rotation, avoid shaking during device operation, and ensure that the yarn shifting member 2 can accurately pick the weft from the yarn storage rack 1, thereby improving the reliability and durability of the entire weft feeding device.

[0049] Further, the transmission cylinder 6 has a cylinder cavity 601, the fixed rod 11 is arranged on the base frame 5 and penetrates the cylinder cavity 601, and the sun gear 3 is arranged at one end of the fixed rod 11.

[0050] In this embodiment, the transmission cylinder 6 has a cylinder cavity 601, the fixed rod 11 is arranged on the base frame 5 and penetrates the cylinder cavity 601, and the sun gear 3 is arranged at one end of the fixed rod 11. When the transmission cylinder 6 rotates, the sun gear 3 rotates around the fixed rod 11 and drives the planetary gear 4 to move through meshing. The fixed rod 11 serves to position and support the sun gear 3, ensuring the accuracy of gear transmission. The arrangement of the fixed rod 11 strengthens the installation stability of the sun gear 3, accurately maintains the center distance of gear transmission, reduces gear misalignment and wear caused by long-term operation, ensures long-term stable operation of the entire weft feeding device, and reduces maintenance cost.

[0051] Further, the yarn storage rack 1 is of a split structure and has a plurality of yarn storage members 9 arranged in a circumferential interval on the mounting table 8. The yarn storage member 9 is detachably arranged on the mounting table 8.

[0052] In this embodiment, the yarn storage rack 1 is composed of multiple independent yarn storage pieces 9, each of which can be individually disassembled and reinstalled. According to different weft requirements, different numbers of yarn storage pieces 9 can be selected for configuration to achieve a highly customized winding scheme. The multiple yarn storage pieces 9 are arranged in a circumferential interval along the mounting table 8, ensuring that the weft can be evenly wound on the yarn storage rack 1, avoiding the problem of local accumulation or uneven winding. The number and position of the yarn storage pieces 9 can be adjusted according to different weft types, diameters, and lengths to meet diverse production needs. The split structure provides redundancy, so even if a certain yarn storage piece 9 fails, the other yarn storage pieces 9 can still continue to work, reducing the risk of system downtime. Each yarn storage piece 9 can be individually replaced or repaired, reducing the overall equipment maintenance time and cost and improving the system's reliability and availability.

[0053] Further, the yarn storage piece 9 has a guide slope 10, which gradually decreases in height from close to the mounting table 8 to far from the mounting table 8, and is arc-shaped.

[0054] In this embodiment, the surface of the guide slope 10 is arc-shaped, providing a smooth transition path. When the weft enters the yarn storage rack 1, it will naturally slide down the slope of the guide slope 10. Due to the gradual decrease in height, the weft can be smoothly guided to the predetermined position of the yarn storage rack 1. The arc-shaped design makes the contact between the weft and the guide slope 10 during movement more gentle, reducing friction and mechanical stress on the weft and reducing the risk of breakage or deformation. The gradual height change and smooth arc-shaped design of the guide slope 10 help the weft form a tight and orderly spiral structure on the yarn storage rack 1, improving the overall winding effect. Whether the weft is soft or hard, the guide slope 10 can provide effective guidance, suitable for winding needs of various materials, and help improve the overall operation efficiency and weaving quality of the loom.
