Description

Technical Field

[0001] This utility model relates to the technical field of yarn guiding mechanisms, specifically a yarn guiding mechanism for a large circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular knitting weft knitting machines (or circular knitting weft knitting machines), have developed rapidly due to their numerous loop-forming systems (referred to as yarn feed paths or loop-forming paths in enterprises, or simply paths), high speed, high output, fast pattern changes, good fabric quality, fewer processes, and strong product adaptability. In the process of using circular knitting machines, yarn guiding mechanisms are used.

[0003] During the yarn guiding process of the circular knitting machine, the yarn moves at high speed, and there is a large friction between the yarn and the guide hole and the feeding hole. Because there are sharp edges on the hole wall, the yarn is prone to breakage due to long-term friction with the hole wall. In addition, when conveying the yarn, there may be insufficient tension and the yarn is conveyed too loosely, which may lead to subsequent yarn tangling. Overall, the practicality is not good.

[0004] Therefore, we propose a yarn guiding mechanism for circular knitting machines to solve the above problems. Utility Model Content

This solves the problems mentioned in the background section regarding the high-speed movement of the yarn during yarn guiding, the significant friction between the yarn and the guide holes and feed holes, and the potential breakage of the yarn due to the sharp edges of the hole walls. Furthermore, existing yarn guiding mechanisms lack a structure for adjusting yarn tension, which can lead to insufficient tension, excessively loose yarn feeding, and subsequent yarn tangling, resulting in poor overall practicality.

[0025] 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.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a yarn guiding mechanism for a large circular knitting machine, including a machine body 1, a support frame 2 fixed to the top of the machine body 1, and an extension seat 3 fixed to one side of the top of the support frame 2. The extension seats 3 are equidistantly distributed along the center point of the support frame 2.

[0028] An adjusting plate 4 is fixedly connected to the inner front end of the extension seat 3, and a first mounting plate 5 is connected to the top front end of the adjusting plate 4. A positioning bolt 6 is connected to one bottom end of the first mounting plate 5, and a first yarn guide wheel 7 is connected to the inner top end of the first mounting plate 5. A first yarn guide groove 8 is formed on the outer ring surface of the first yarn guide wheel 7. The first yarn guide wheel 7 is rotatably connected to the first mounting plate 5 through a bearing seat, and the inner side wall of the first yarn guide groove 8 is arc-shaped. A second mounting plate 9 is fixedly connected to the front bottom end of the adjusting plate 4, and a second yarn guide wheel 10 is rotatably connected to the inner side of one end of the second mounting plate 9. A second yarn guide groove 11 is provided on the annular surface. A guide groove 12 is provided at the bottom front end of the adjusting plate 4. A lock hole 13 is connected to one side of the guide groove 12. A slider 14 is distributed on the inner side of the guide groove 12. A linkage rod 15 is rotatably connected to the front end of the slider 14. One end of the linkage rod 15 is rotatably connected to the slider 14 through a connecting ear, and the other end is rotatably connected to the push plate 16 through a connecting ear. The other end of the linkage rod 15 is rotatably connected to the push plate 16. A tension roller 17 is rotatably connected to the inner side of the end of the push plate 16 away from the linkage rod 15. The linkage rod 15 is rotatably connected to the push plate 16 through a bearing seat.

[0029] In use, the extension seat 3 is pre-fixed onto the surface of the support frame 2. Then, the yarn is passed through the slot opened on one end surface of the first mounting plate 5, and the yarn moves along the first guide groove 8 opened on the outer ring surface of the first guide wheel 7. Since the bottom of the inner wall of the first guide groove 8 is arc-shaped, the first guide groove 8 can effectively protect and limit the yarn. Then, in conjunction with the rotatable first guide wheel 7, the yarn can be effectively prevented from breaking due to friction during the conveying process. After the initial guidance, the yarn will pass through the tension roller 17, and the tension roller 17 will effectively tension the yarn. After being tensioned, the yarn moves along the second guide groove 11 on the outer ring of the second guide roller 10, which further assists in the yarn transport. When it is necessary to adjust the position of the tension roller 17 to perform different degrees of yarn tensioning, the slider 14 is pushed so that it slides longitudinally along the guide groove 12. When the slider 14 slides, it pushes the linkage rod 15 connected to its front end, which in turn pushes the push plate 16 connected to its other end through the connecting ear. Then the push plate 16 rotates along the adjusting plate 4, thereby realizing the adjustment of the position of the tension roller 17, which facilitates the subsequent different degrees of yarn tensioning.

[0030] like Figure 2 and Figure 4As shown, in some embodiments, a return spring 18 is fixedly connected to the inner sidewall of the slider 14, and a locking rod 19 is fixedly connected to the other end of the return spring 18. The two ends of the return spring 18 are respectively fixedly connected to the inner sidewall of the slider 14 and one end surface of the locking rod 19. An auxiliary sliding plate 20 is fixedly provided on the outer ring surface of one end of the locking rod 19.

[0031] In use, when the slider 14 slides to a suitable position inside the guide groove 12, the locking rod 19 moves to one side of the lock hole 13. At this time, the pressure applied to the locking rod 19 disappears, and then the reverse force generated by the deformation of the return spring 18 will push the locking rod 19 in the opposite direction, thereby inputting one end of the locking rod 19 into the inside of the lock hole 13 to perform the positioning of the slider 14. The auxiliary slide plate 20 can improve the stability of the locking rod 19 during the movement.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the first yarn guide wheel 7 is rotatably connected to the first mounting plate 5 through a bearing seat, and the first yarn guide groove 8 is equidistantly distributed along the outer ring surface of the first yarn guide wheel 7;

[0033] When in use, when the yarn passes through the first guide wheel 7, it will move along the first guide groove 8 opened on the outer ring surface of the first guide wheel 7, which facilitates the subsequent use of the first guide groove 8 to guide the yarn delivery. At the same time, the arc-shaped surface on the inner side wall of the first guide groove 8 can effectively prevent the yarn from being broken by friction.

[0034] like Figure 2 and Figure 3 As shown, in some embodiments, the guide grooves 12 are symmetrically distributed along the vertical center line of the adjustment plate 4, and the guide grooves 12 and the adjustment plate 4 form an integrated structure.

[0035] In use, since the guide grooves 12 are symmetrically distributed along the adjustment plate 4, the stability of the slider 14 during its movement can be easily improved when the slider 14 slides along the guide grooves 12.

[0036] like Figure 2 and Figure 3 As shown, in some embodiments, the lock holes 13 are equidistantly distributed on one side of the bottom of the adjustment plate 4, and the inner diameter of the lock holes 13 is adapted to the outer diameter of the lock rod 19;

[0037] When in use, since the size of the lock hole 13 is compatible with the size of the lock rod 19, it is convenient to position the slider 14 after the lock rod 19 is inserted into the inside of the lock hole 13.

[0038] like Figure 2 and Figure 4As shown, in some embodiments, one end of the linkage rod 15 is slidably connected to the slider 14 via a connecting ear, and the other end of the linkage rod 15 is rotatably connected to the push plate 16 via a connecting ear.

[0039] When in use, when the slider 14 slides along the guide groove 12, it will push the linkage rod 15, which in turn will push the push plate 16, making it easier for the push plate 16 to rotate along the front surface of the adjustment plate 4.

[0040] In summary, during use, the extension seat 3 is pre-fixed onto the surface of the support frame 2. Then, the yarn is passed through the first mounting plate 5 and moves along the first guide groove 8 on the outer ring surface of the first guide wheel 7. The rotatable first guide wheel 7 effectively prevents the yarn from breaking due to friction during transport. After initial guidance, the yarn passes through the tension roller 17, which effectively tensions the yarn. The tensioned yarn then moves along the second guide groove 11 on the outer ring surface of the second guide wheel 10, further assisting in yarn transport. When the position of the tension roller 17 needs adjustment, the slider is pushed. 14. The slider 14 slides longitudinally along the guide groove 12. When the slider 14 slides, it pushes the linkage rod 15, which in turn pushes the push plate 16 to adjust the position of the tension roller 17. This facilitates subsequent tensioning of the yarn to different degrees. When the slider 14 slides to the appropriate position inside the guide groove 12, the locking rod 19 moves to one side of the locking hole 13. At this time, the pressure applied to the locking rod 19 disappears, and the reverse force generated by the deformation of the return spring 18 pushes the locking rod 19 in the opposite direction, thereby inputting one end of the locking rod 19 into the inside of the locking hole 13 to perform the positioning of the slider 14. The auxiliary slide plate 20 can improve the stability of the locking rod 19 during its movement.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
