[0042] Reference Figure 1-Figure 6 A yarn guide device for a circular knitting machine comprises a bearing seat 1, a yarn guide wheel 2 and an elastic limit assembly 3. The bearing seat 1 is composed of a bottom plate 11 and side plates 12 arranged on both sides of the bottom plate 11. Through holes 121 are arranged on the two groups of side plates 12. Since the two groups of through holes 121 are respectively located on both sides of the bottom plate 11, the two groups of through holes 121 form a yarn outlet hole and a yarn inlet hole of the yarn guide device. The yarn guide wheel 2 is arranged on the bottom plate 11. The yarn guide wheel 2 is used to reduce friction with the yarn to ensure smooth sliding of the yarn. When the yarn extends from the through hole 121 on one side to the through hole 121 on the other side, the yarn needs to contact the yarn guide wheel 2 and the elastic limit assembly 3.

[0043] The elastic limiting assembly 3 includes a cushion block 31, a guide rod 32, an elastic member 33 and a support plate 34. The cushion block 31 is located on one side of the yarn guide wheel 2. The cushion block 31 is made of rubber material to avoid damage to the yarn. A limited area is formed between the cushion block 31 and the bottom plate 11. The yarn is located in the limited area. The guide rod 32 is provided with two groups and is respectively arranged on both sides of the cushion block 31. The two groups of guide rods 32 are evenly connected to the cushion block 31.

[0044] One end of the guide rod 32 passes through the base plate 11 and is located outside the base plate 11. The support plate 34 is connected to the guide rod 32 located outside the base plate 11. The elastic member 33 is located between the base plate 11 and the support plate 34. There are several elastic members 33, and the elastic members 33 are evenly distributed along the length direction of the support plate 34. One end of the elastic member 33 is connected to the base plate 11, and the other end is connected to the support plate 34. According to the cooperation between the support plate 34 and the elastic member 33, when the support plate 34 approaches or moves away from the base plate 11, the range of the limiting area increases or decreases.

[0045] Based on the above structure, the yarn passes through the through hole 121 at one end and out of the through hole 121 at the other end. When part of the yarn is located in the supporting seat 1, the yarn contacts the rotating yarn guide wheel 2, which is convenient for the transportation of the yarn. The elastic limiting component 3 is located between the side plate 12 and the yarn guide wheel 2. Since the yarn is located in the limiting area formed by the cushion block 31 and the bottom plate 11, and is connected to the cushion block 31 and the support plate 34 through the guide rod 32, when the support plate 34 moves away from the bottom plate 11 under the action of the elastic member 33, the cushion block 31 will lean against the bottom plate 11 until it is against the bottom plate 11, so that the yarn is subjected to the pressure applied by the bottom plate 11 and the cushion block 31, thereby completing the limitation of the yarn. It can only move in a straight line but cannot sway left and right, and the pad 31 squeezes the yarn to keep uniform tension during transmission. The setting of the elastic limit assembly 3 can achieve the fixation of the yarn through the cooperation between the pad 31 and the base plate 11, and since the support plate 34 is connected to the pad 31 through the guide rod 32, and an elastic member 33 is connected between the support plate 34 and the base plate 11, the thickness of the yarn can be adaptively adjusted according to the characteristics of the elastic member 33 itself, thereby improving the flexibility of the elastic limit assembly 3, avoiding the shaking of the yarn during transportation, and solving the problem of yarn breakage during transportation due to shaking.

[0046] The elastic member 33 can be any one of a telescopic spring, a pressure spring or a torsion spring in the prior art.

[0047] In one embodiment, referring to Figure 1 , Figure 4 and Figure 6, further comprising a tension component 4, the tension component 4 being located on a side of the yarn guide wheel 2 away from the elastic limiting component 3, and the tension component 4 being used to increase the tension of the yarn during transportation;

[0048] The tension assembly 4 includes a support component 41 and a tension roller 42. The support component 41 has two groups and is spaced apart on the bottom plate 11. Both ends of the tension roller 42 are evenly rotated and set on the two groups of support components 41. When they are on the same horizontal plane, the height of the tension roller 42 is higher than the height of the yarn guide wheel 2. Through the height difference, when the yarn is against the outer periphery of the yarn guide wheel 2, the yarn will be tightened. This natural tightening effect can increase the tension of the yarn, making it more stable during the weaving process and reducing the situation of broken thread or loosening.

[0049] The supporting component 41 is composed of a fixing seat 411 and a connecting frame 412. The fixing seat 411 is disposed on the bottom plate 11 and has a receiving groove 4111.

[0050] One end of the connecting frame 412 is sleeved in the receiving groove 4111, and the other end is rotatably connected to the tension roller 42. When one end of the connecting frame 412 moves in the receiving groove 4111, the height of the tension roller 42 also changes synchronously. Since the height of the tension roller 42 changes with the position of one end of the connecting frame 412 in the receiving groove 4111, the position of the connecting frame 412 can be changed according to actual operating conditions, thereby achieving different degrees of tension adjustment for different yarns.

[0051] In one embodiment, referring to Figure 1-Figure 5 , further comprising a yarn splitting plate 5, two groups of slots 122 spaced apart are provided on the side plate 12, the through hole 121 is located between the two groups of slots 122, a protrusion 51 is provided at the position of the yarn splitting plate 5 corresponding to the slot 122, and the yarn splitting plate 5 is connected to the side plate 12 by embedding the protrusion 51 into the slot 122, and a plurality of yarn threading holes 52 spaced apart are provided on the yarn splitting plate 5;

[0052] A plurality of spaced-apart limiting grooves 311 are provided on the side of the pad 31 facing the base plate 11, and a plurality of spaced-apart yarn grooves 421 are provided on the tension roller 42. By providing the yarn threading hole 52 on the yarn dividing plate 5, it is possible to place a plurality of yarns on a yarn guiding device. In addition, by cooperating with the yarn threading hole 52, the spaced-apart limiting grooves 311 and the yarn grooves 421, it is possible to prevent different yarns from interfering with each other, thereby avoiding entanglement during transportation and improving the load-bearing capacity of the yarn guiding device. Since the yarn dividing plate 5 is connected to the slot 122 of the side plate 12 via the protrusion 51, the installation of the yarn dividing plate 5 can be adjusted according to actual usage.

[0053] In one embodiment, referring to Figure 1 , Figure 2 , Figure 3 and Figure 6 , a first magnetic layer 1221 is provided in the slot 122 , and a second magnetic layer 511 is provided on a side of the protrusion 51 facing the slot 122 ;

[0054] Through the cooperation of the first magnetic layer 1221 and the second magnetic layer 511, when the protrusion 51 is embedded in the slot 122, the yarn separating plate 5 and the side plate 12 are magnetically connected. In order to enhance the stability of the connection between the yarn separating plate 5 and the side plate 12, they can be firmly connected through magnetic connection.

[0055] In one embodiment, referring to Figure 1 A mounting frame 111 is provided at the bottom of the base plate 11, and the mounting frame 111 is connected to the bracket on the circular knitting machine, so that the yarn guiding device is located above the circular knitting machine, which is convenient for conveying yarn to the circular knitting machine.

[0056] In one embodiment, referring to Figure 1 and Figure 2 A handle portion 312 is provided on the side of the pad 31 away from the bottom plate 11. When the yarn needs to be placed, the pad 31 needs to be separated from the bottom plate 11 to facilitate the placement of the yarn between the pad 31 and the bottom plate 11. Therefore, the setting of the handle portion 312 makes it easier for the operator to lift the pad 31.
