Description

Technical Field

[0001] The present invention relates to the technical field of large circular knitting machines, and in particular to a yarn feeding device for a circular knitting machine. Background Art

[0002] During the knitting process of the large circular knitting machine, the yarn is guided to the needle tongue by the yarn feeding device so that the yarn is pulled by the knitting hook to work. Since the bending angle of the guide plate on the traditional yarn feeding device is fixed and cannot be adjusted, during the knitting process, the friction force is easily increased when guiding the yarn, resulting in uneven yarn tension, which can cause the guide yarn eye to wear and even cause the yarn to break.

[0035] Reference Figure 1-Figure 8 , a yarn feeding device for a circular knitting machine, comprising a body 1, a yarn guide portion 2, and a yarn feeding portion 3, wherein the body 1 is located between the yarn guide portion 2 and the yarn feeding portion 3;

[0036] The upper part of the body 1 is provided with a rotating part 11 and a guide plate 12. The rotating part 11 includes a fixed shaft 111, a rotating shaft 112 and an adjusting button 113. The rotating shaft 112 is movably installed inside the fixed shaft 111. The fixed shaft 111 is provided with an opening 1111. One end of the guide plate 12 passes through the opening 1111 and is fixedly connected to the internal rotating shaft 112. The adjusting button 113 is provided with two groups. The two groups of adjusting buttons 113 are symmetrically distributed on both sides of the rotating shaft 112 and are both arranged in a hexagonal structure. The adjusting buttons 113 on both sides are arranged to facilitate the operator to adjust the directions of both sides of the yarn feeding device, thereby improving the use flexibility of the yarn feeding device. The hexagonal structure setting also makes the adjusting button 113 have better smooth performance during use. By rotating the adjusting button 113, the guide plate 12 can be rotated along the path of the opening 1111, and the angle of the yarn guide part 2 can be adjusted to change the direction of the yarn, thereby reducing the friction coefficient, making the yarn tension uniform and stable, preventing the situation of yarn breakage caused by direct pulling, and improving work efficiency.

[0037] The yarn guiding portion 2 is located above the yarn feeding portion 3, and is provided with a guide yarn eye 21 and a first guide groove 22. The guide yarn eye 21 is arranged at the end of the yarn guiding portion 2 away from the guide plate 12, and the guide yarn eye 21 and the first guide groove 22 are distributed at both ends of the yarn guiding portion 2 at intervals. The guide yarn eye 21 is located at the end of the yarn guiding portion 2 away from the guide plate 12, and the first guide groove 22 is located at the end of the yarn guiding portion 2 close to the guide plate 12. The yarn guiding portion 2 is snap-fitted with the first engaging opening 121 through the first guide groove 22, which is convenient for installing and disassembling the yarn guiding portion 2, is conducive to replacing the worn guide yarn eye 21, reduces the yarn breakage rate, and improves the quality of the woven fabric.

[0038] A second engaging opening 13 connected to the yarn feeding part 3 is also provided at the lower end edge of the main body 1, and a ceramic eye 31 and a second guide groove 32 are provided on the yarn feeding part 3. The ceramic eye 31 is arranged at the end of the yarn feeding part 3 away from the main body 1. The ceramic eye 31 is made of ceramic material and has stronger wear resistance. The second guide groove 32 is located at the end of the yarn feeding part 3 close to the second engaging opening 13. The yarn feeding part 3 is snap-fitted with the second engaging opening 13 through the second guide groove 32, which is convenient for installing and disassembling the yarn feeding part 3, is conducive to replacing the worn ceramic eye 31, reduces the yarn breakage rate, and improves the quality of the woven fabric.

[0039] Based on the above structure, since one end of the guide plate 12 passes through the opening 1111 and is fixedly connected to the rotating shaft 112, when the yarn passes through the guide yarn eye 21 and is guided to the porcelain eye 31, the guide plate 12 can be rotated along the path of the opening 1111 by rotating the rotating shaft 112, so that the angle of the yarn guide part 2 can be adjusted to change the direction of the yarn, thereby reducing the friction coefficient, making the yarn tension uniform and stable, and preventing the yarn from breaking due to direct pulling. The yarn guide part 2 is connected to the first fitting mouth 121 through the first guide groove 22, so that the first guide groove 22 and the first fitting mouth 121 form a detachable structure, which can facilitate the installation or disassembly of the yarn guide part 2, and realize the quick and convenient replacement of the guide yarn eye 21, avoiding the operator's uneven tension and increased friction coefficient during the weaving process, which makes the guide yarn eye 2 easy to wear and increase the yarn breakage rate.

[0040] In one embodiment, referring to Figure 1-Figure 8 The first fitting opening 121 and the second fitting opening 13 are both provided with a U-shaped structure, and a magnetic pole is provided in the concave side. The first guide groove 22 and the second guide groove 32 are both provided with a cross-shaped structure, and the cross-shaped structure and the U-shaped structure are used for buckling connection. After buckling, it is not easy to deviate, and it has a limiting effect. The first guide groove 22 and the second guide groove 32 are made of magnetic material, and the magnetic pole is magnetically connected to the first guide groove 22 and the second guide groove 32, so that it is not easy to fall off during the weaving process, which facilitates more stable limiting.

[0041] In one embodiment, referring to Figure 4 A fixing seat 14 and a limiting groove 15 for fixing on the support ring are provided in the middle of the main body 1. The main body 1 is fixed to one side of the fixing seat 14 through the limiting groove 15 by a fastener 4. The main body 1 can move vertically in the limiting groove 15 under the support of the fastener 4, and has good versatility.

[0042] In one embodiment, referring to Figure 1-Figure 4 and Figure 6 The main body 1 is also provided with a through hole 16, and the through hole 16 is provided with two groups. The two groups of through holes 16 are symmetrically arranged on both sides of the limiting groove 15. According to different yarn and knitting needle requirements, the yarn guide wheel can be inserted into the through hole 16 to adjust the direction of the yarn to obtain the best weaving effect.
