[0036] Reference Figure 1-Figure 7 A yarn feeder for a knitting machine comprises a guide plate 1, a yarn guide plate 2 and a yarn feeding plate 3, wherein the guide plate 1 is movably connected to the yarn guide plate 2, and the yarn feeding plate 3 is arranged in an L-shaped structure. The L-shaped structure is advantageous for improving the efficiency of installing and removing the yarn feeding plate 3, and is advantageous for users to thread yarn more conveniently, reduce the yarn breakage rate, and improve the quality of knitted fabrics;

[0037] The lower end of the guide plate 1 is provided with an engaging opening 11, and a pressing mechanism 12 is provided in the engaging opening 11. The pressing mechanism 12 includes a pull rod 121, a slider 122 and a return spring 123. The slider 122 is located between the pull rod 121 and the return spring 123. The slider 122 is provided with a guide groove 1221 and a hook 1222. The guide groove 1221 and the hook 1222 are spaced apart and distributed at both ends of the slider 122. The guide groove 1221 has a first guide rail 12211, a second guide rail 12212 and a groove 12213. The groove 12213 is located between the first guide rail 12211 and the second guide rail 12212. One end of the second guide rail 12212 is connected to the groove 12213, and the other end of the second guide rail 12212 is connected to the first guide rail 12211.

[0038] One end of the first guide rail 12211 gradually tilts toward the other end close to the groove 12213, and forms a drop between the first guide rail 12211 and the groove 12213; one end of the second guide rail 12212 close to the groove 12213 is lower than the groove 12213; one end of the second guide rail 12212 close to the groove 12213 gradually tilts toward the other end away from the groove 12213, and is connected to the first guide rail 12211, so that the pull rod 121 can only move along a specific track of the guide groove 1221, but cannot move in reverse, thereby improving the efficiency of installing and removing the yarn feeding plate 3;

[0039] Through the cooperation between the pull hook 1222 and the yarn feeding plate 3, the yarn feeding plate 3 is installed or popped out in the fitting opening 11. After the pull hook 1222 hooks the yarn feeding plate 3, it is not easy to be separated, which has a limiting effect. One end of the pull rod 121 is fixedly connected to the guide plate 1, and the other end moves along the path of the guide groove 1221. One end of the return spring 123 is fixedly connected to the guide plate 1, and the other end is connected to the end of the slider 122 away from the guide groove 1221.

[0040] When the yarn feeding plate 3 is pressed into the fitting opening 11, the yarn feeding plate 3 pushes the slider 122 to move inward. During the movement of the slider 122, the pull rod 121 moves along the path of the guide groove 1221, thereby changing the position of the yarn feeding plate 3.

[0041] The yarn guide plate 2 is provided with a guide yarn eye 21, which is arranged at the end of the yarn guide plate 2 away from the guide plate 1, and the guide yarn eye 21 is located above the yarn feeding plate 3, and the yarn feeding plate 3 is provided with a porcelain eye 31 and a locking groove 32. The porcelain eye 31 is made of ceramic material and has stronger wear resistance, thereby reducing the friction coefficient and improving the quality of the woven fabric. The porcelain eye 31 is arranged at the end of the yarn feeding plate 3 away from the guide plate 1, and the locking groove 32 is arranged at the end of the yarn feeding plate 3 close to the guide plate 1. The locking groove 32 and the hook 1222 are snap-fitted and connected, so that it is not easy to cause deviation during the weaving process, which facilitates more stable limiting.

[0042] The return spring 123 may be a tension spring.

[0043] Based on the above structure, since the pressing mechanism 12 is provided in the fitting opening 11, during installation, the user presses the yarn feeding plate 3 into the fitting opening 11, and the yarn feeding plate 3 pushes the slider 122 in the pressing mechanism 12 to move inward. During the movement of the slider 122, the pull rod 121 in the pressing mechanism 12 moves along the path of the guide groove 1221 provided on the slider 122. When the pull rod 121 moves to the groove 12213 provided in the guide groove 1221, and the pull hook 1222 provided on the slider 122 is engaged with the locking groove 32 provided on the yarn feeding plate 3, the yarn feeding plate 3 is fixed in the fitting opening 11. To achieve the connection, once the porcelain eye 31 is worn and needs to be replaced, the yarn feeding plate 3 is pressed again, and the yarn feeding plate 3 will push the slider 122 to continue to move inward, and the pull rod 121 continues to move along the path of the guide groove 1221, so that the pull rod 121 leaves the groove 12213 and returns to the starting point, and the slider 122 is reset to its initial position under the action of the reset spring 123, so that the yarn feeding plate 3 can be quickly and conveniently removed from the guide plate 1. This design improves the efficiency of installation and disassembly of the porcelain eye 31, and solves the problem that the porcelain eye 31 of the traditional yarn feeder needs to be disassembled when it is worn, which not only wastes working time but also increases production costs.

[0044] In one embodiment, referring to Figure 1-Figure 4, and also includes a base 4 and a limiting bolt 5. A limiting groove 41 is provided in the middle of the base 4. The limiting groove 41 fixes the guide plate 1 and the yarn guide plate 2 in the limiting groove 41 through the limiting bolt 5, which is not easy to deviate and has a limiting effect.

[0045] In one embodiment, referring to Figure 1-Figure 3 The guide plate 1 is also provided with an adjusting groove 13 and a through hole 14. The adjusting groove 13 is located at one end away from the fitting opening 11. Through the cooperation of the limit bolt 5 and the adjusting groove 13, the guide plate 1 can change its position, thereby improving the performance of the yarn feeder. The through hole 14 is located between the fitting opening 11 and the adjusting groove 13. According to the requirements of different yarns and knitting needles, the yarn guide wheel can be inserted into the through hole 14, thereby adjusting the direction of the yarn and improving the quality of the woven fabric.
