[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figures 1-3 The illustrated double-jet weft feeder includes a feeder body 1, a guide wire opening 2, a support mechanism 3, and an adjustment mechanism 4. The guide wire opening 2 is located on the front of the feeder body 1. One end of the yarn passes through the inner cavity of the guide wire opening 2 and enters the inner cavity of the feeder body 1. The support mechanism 3 is located on the guide wire opening 2 and is used to support and limit the yarn. By supporting and limiting the yarn passing through the guide wire opening 2, the support mechanism 3 prevents the yarn from rubbing against the inner wall of the guide wire opening 2 and reduces wear on the yarn. The adjustment mechanism 4 is located on the support mechanism 3 and is used to adjust the tension of the support mechanism 3. By adjusting the angle of the support mechanism 3, the adjustment mechanism 4 ensures that the support mechanism 3 tensions the yarn.

[0033] Specifically, the support mechanism 3 includes a movable rod 31, a connecting shaft 32, a support roller 33, a limiting groove 34, and a rotating shaft 35. The movable rods 31 are located on both sides of the guide opening 2, with two movable rods 31 on each side. The movable rods 31 are used to mount the support rollers 33 and drive their movement. One end of the connecting shaft 32 is fixedly connected to one side of the outer wall of the guide opening 2, and the other end of the connecting shaft 32 is rotatably connected to the other end of the movable rod 31. One end of the movable rod 31 is rotatably connected to one side of the guide opening 2 via the connecting shaft 32, allowing the movable rod 31 to rotate around the connecting shaft 32, facilitating the adjustment of the angle between the movable rod 31 and the support roller 33. The support roller 33 is located at the guide opening... On the front of 2, the support rollers 33 are arranged vertically. The support rollers 33 are used to support the yarn. One end of the yarn is inserted between the two support rollers 33. The limiting groove 34 is set in the middle of the support rollers 33. One end of the yarn is set between the inner cavities of the two limiting grooves 34, which plays a limiting role for the yarn and prevents the yarn from deviating. The rotating shaft 35 is fixedly inserted and connected to the support rollers 33. One end of the rotating shaft 35 is rotatably inserted and connected to the other end of the movable rod 31. The support rollers 33 are rotatably connected to the other end of the movable rod 31 through the rotating shaft 35, so that the support rollers 33 rotate around the rotating shaft 35, which facilitates the feeding of the yarn and reduces the frictional resistance between the yarn and the outer wall of the support rollers 33.

[0034] Furthermore, the adjusting mechanism 4 includes a movable groove 41, a connecting rod 42, a movable ring 43, a fixing block 44, a compression spring 45, and a fastening bolt 46. The movable groove 41 is located at one end of the movable rod 31 and is used to install the connecting rod 42, facilitating the movement of the connecting rod 42. One end of the connecting rod 42 is slidably inserted into the inner cavity of the movable groove 41. The connecting rod 42 is positioned between the movable rods 31 and is used to limit and fix the two movable rods 31 on the same side, ensuring the stability of the movable rods 31 and the support roller 33. The connecting rod 42 slides in the inner cavity of the movable groove 41, and the movable ring 43 is connected to the connecting rod 44. One end of the connecting rod 42 is slidably inserted and connected. One end of the movable ring 43 is in contact with the outer wall of the movable rod 31. One end of the movable ring 43 is curved. The movable ring 43 is used to compress and deform the movable rod 31 to ensure the stability of the movable rod 31. The fixed block 44 is fixedly connected to one end of the connecting rod 42. The fixed block 44 is used to limit the compression spring 45. The compression spring 45 is movably sleeved with one end of the connecting rod 42. The compression spring 45 is set between the fixed block 44 and the movable ring 43. The elasticity of the compression spring 45 is used to compress and push the movable ring 43, so that the outer wall of the movable ring 43 is in contact with the movable rod 31. The fastening bolt 46 is tightened. One end of the bolt 46 is threaded to one side of the movable ring 43. One end of the fastening bolt 46 is pressed against the outer wall of the connecting rod 42. By rotating the fastening bolt 46, one end of the fastening bolt 46 is pressed against the connecting rod 42, which in turn presses and fixes the movable ring 43, ensuring that the movable ring 43 stably limits and fixes the movable rod 31. The front of the guide wire opening 2 is provided with a through hole, which corresponds to the position of the support roller 33. The limiting groove 34 is set in an arc-shaped groove. The guide wire opening 2 is used to insert and set the yarn. By inserting one end of the yarn between the two support rollers 33, the yarn slides in the inner cavity of the two limiting grooves 34, and then the compression spring 45 is used to... The elastic action compresses and pushes the movable ring 43, causing it to slide along both ends of the connecting rod 42. The outer wall of the movable ring 43 fits against the movable rod 31. Rotating the fastening bolt 46 causes one end of the fastening bolt 46 to compress the connecting rod 42, thus compressing and fixing the movable ring 43. This limits and fixes the movable rod 31, ensuring the stability of the support roller 33. As the yarn is conveyed, it slides in the inner cavity of the limiting groove 34, which limits the yarn and prevents it from deviating. It also reduces the frictional resistance between the yarn and the outer wall of the support roller 33, facilitating the conveying of the yarn.
