Description

Technical Field

[0001] This application relates to the field of large-width double-sided knitting machine technology, and more particularly to a yarn guiding device for a large-width double-sided knitting machine. Background Technology

[0002] A large-width double-sided knitting machine is a type of knitting machinery typically used to produce double-sided fabrics. During the knitting process, the yarn needs to be fed into the knitting area in a specific order and path through a yarn guide device. The yarn can accurately enter the various needle positions of the knitting system for orderly knitting. However, since the tension required by existing yarns varies, and the existing yarn guide devices cannot adjust the tension, unstable yarn tension during the yarn feeding process can lead to uneven fabric density, thus affecting the appearance and feel of the fabric. Enterprises need to equip themselves with yarn guide devices of different tensions to adapt to different yarns, which increases the enterprise's procurement and maintenance costs. Utility Model Content

[0013] In one embodiment, a support seat is provided on the connecting rod, the support seat has an opening, a receiving rod is provided in the opening, a bearing seat is rotatably provided on the receiving rod, and the bearing seat is connected to the third guide wheel.

[0014] The cooperation between the bearing seat and the receiving rod enables the third guide wheel to rotate in a circle with the receiving rod as the center.

[0015] In one embodiment, a receiving groove is provided at one end of the support rod near the second guide wheel, and a movable rod is provided at the bottom of the second guide wheel, with part of the movable rod embedded in the receiving groove;

[0016] The second guide wheel is moved closer to or away from the support rod by the movement of the movable rod within the receiving groove.

[0017] In one embodiment, a sleeve is provided at the bottom of the support plate, and the sleeve is fitted onto the annular protrusion.

Since the support rod connecting the second guide roller is threaded onto a limiting shaft, and the limiting shaft has several through holes in the mounting base, the position of the second guide roller can be changed by installing the limiting shaft into different through holes. Furthermore, since the connecting rod connected to the third guide roller is connected to a sliding seat located on the slide groove, the position of the third guide roller can be changed by moving the sliding seat, thereby adjusting the distance between the second and third guide rollers. The tension borne by the yarn during the movement also changes, thus enabling adjustment of the tension required for different types of yarn. This solves the problem that existing yarn guiding devices can only provide a single tension to the yarn and cannot adjust according to the yarn condition, resulting in unstable yarn tension.

[0043] The names of the messages or information exchanged between multiple devices in the embodiments of this application are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0044] Reference Figures 1-6 A yarn guiding device for a large-width double-sided machine includes a machine body 1, a yarn frame 11 on the machine body 1, and several yarn guiding mechanisms spaced apart along the circumference of the yarn frame 11. The several yarn guiding mechanisms are used to guide multiple yarns. The yarn guiding mechanism includes a mounting plate 2 and a placement seat 3. The placement seat 3 is disposed on the mounting plate 2. The mounting plate 2 has a bearing plate 21 distributed perpendicularly to the mounting plate 2. The bearing plate 21 has a hollow part. A rod 211 is disposed in the hollow part. A first yarn guiding wheel 212 is sleeved on the rod 211. The first yarn guiding wheel 212 is used to guide the external yarn to the position of the placement seat 3.

[0045] The storage base 3 has through holes 31, and several through holes 31 are provided and distributed at intervals along the length of the storage base 3. The through holes 31 have mounting holes 311, one end of which extends to the outside of the storage base 3. A guide wheel component 4 is installed in one group of through holes 31. The arrangement of several through holes 31 can adjust the guide wheel component 4 to different positions according to the yarn characteristics and needs.

[0046] The guide wheel component 4 includes a limiting shaft 41, which is movably installed in one of the through holes 31. The limiting shaft 41 has a through groove 411 communicating with the mounting hole 311. The through groove 411 has a threaded groove. A support rod 42 is threadedly connected to the through groove 411. The other end of the support rod 42 extends through the mounting hole 311 to the outside of the holder 3 and is equipped with a second guide wheel 43. The support rod 42 can be fixed to the limiting shaft 41 by means of threaded connection, and the limiting shaft 41 plays a limiting role in the through hole 31.

[0047] A groove 32 is provided on the side of the storage base 3 away from the mounting hole 311. A sliding seat 33 is movably disposed in the groove 32. A connecting rod 5 is provided on the sliding seat 33. The other end of the connecting rod 5 is connected to a third guide wheel 51. Through the cooperation of the groove 32, the sliding seat 33 can drive the connecting rod 5 to move relative to each other along the length direction of the groove 32, thereby changing the position of the third guide wheel 51.

[0048] The second guide roller 43 and the third guide roller 51 are staggered or parallel on both sides of the holder 3. The first guide roller 212 is located between the second guide roller 43 and the third guide roller 51. By staggering the second guide roller 43 and the third guide roller 51, the tension of the yarn can be adjusted when it moves.

[0049] Based on the above structure, the external yarn is drawn onto the first guide roller 212 on the mounting plate 2, then extends into the storage seat 3 and is drawn onto the second guide roller 43 and the third guide roller 51 respectively. Since the second guide roller 43 is mounted on the limiting shaft 41 via the support rod 42, and the storage seat 3 has several through holes 31 for mounting the limiting shaft 41, the position of the second guide roller 43 is changed by mounting the limiting shaft 41 onto one set of through holes 31. Furthermore, the connecting rod 5 connected to the third guide roller 51 is movably mounted on the sliding groove 32 via the sliding seat 33. The movement of the sliding seat 33 can drive the third guide wheel 51 to change its position, thereby forming an "S"-shaped multi-stage yarn guiding path between the second guide wheel 43 and the third guide wheel 51, dispersing the tension concentration point, avoiding yarn breakage or slack, and increasing or decreasing the distance between the second guide wheel 43 and the third guide wheel 51 according to the tension requirements of the yarn, thereby adjusting the tension required when the yarn moves. It can be flexibly adjusted according to actual needs, solving the problem that existing yarn guiding devices can only provide a single tension to the yarn, resulting in unstable yarn tension and uneven fabric density.

[0050] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 4 and Figure 7 The top of the bearing plate 21 is provided with an annular protrusion 213, and a support plate 6 is provided on the annular protrusion 213. A screw rod 61 is threadedly connected to the support plate 6. A mounting bracket 62 is provided at the bottom of the screw rod 61. A shaft rod 621 is provided on the mounting bracket 62. A roller 622 is sleeved on the shaft rod 621. Part of the roller 622 is located outside the mounting bracket 62. The roller 622 is used to abut against the yarn.

[0051] The roller 622 is located above the holder 3. Through the cooperation of the screw 61, the roller 622 can be moved closer to or away from the yarn, so that it can be adjusted according to different yarn characteristics. By rotating the screw 61, the vertical height of the roller 622 can be precisely controlled, so that it is closer to or away from the holder 3, and the yarn tension or contact pressure can be flexibly adjusted to avoid yarn breakage or loosening.

[0052] A sleeve 63 is provided at the bottom of the support plate 6. The sleeve 63 is fitted onto the annular protrusion 213. Through the cooperation of the sleeve 63 and the annular protrusion 213, the support plate 6 can rotate circumferentially around the annular protrusion 213, causing the screw 61 to rotate relative to it. The circumferential rotation of the support plate 6 drives the screw 61 to rotate synchronously, realizing the multi-directional position adjustment of the roller 622. Furthermore, when the roller 622 contacts the yarn, the rotation can drive the yarn to change its angle of movement, further adjusting the yarn tension.

[0053] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5 The connecting rod 5 is provided with a support seat 52, which has an opening. A receiving rod 521 is provided in the opening, and a bearing seat 522 is rotatably provided on the receiving rod 521. The bearing seat 522 is connected to the third guide wheel 51. Through the cooperation of the bearing seat 522 and the receiving rod 521, the third guide wheel 51 can rotate in a circle with the receiving rod 521 as the center. By rotating the third guide wheel 51, the yarn movement path can be changed, thereby increasing the tension generated during movement and dynamically adapting to changes in the yarn path, reducing the risk of yarn deviation or entanglement.

[0054] In one embodiment, reference is made to Figure 1 , Figure 4 and Figure 8 The support rod 42 has a receiving groove 421 at one end near the second guide wheel 43. The bottom of the second guide wheel 43 has a movable rod 431, part of which is embedded in the receiving groove 421. By moving the movable rod 431 in the receiving groove 421, the second guide wheel 43 can be moved closer to or away from the support rod 42, thereby adjusting the horizontal displacement of the second guide wheel 43. This facilitates adjusting the spacing between the guide wheels according to the yarn specifications, thereby adjusting the yarn on the second guide wheel 43 and changing the tension during movement.

[0055] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 7 The roller component 622 is provided with a yarn placement groove 6221. There are several yarn placement grooves 6221 and they are distributed at intervals along the length direction of the roller component 622. Each yarn placement groove 6221 independently accommodates a single yarn, preventing multiple yarns from rubbing or tangling with each other, realizing the separate management of yarns. The groove spacing is designed according to the yarn diameter to ensure that the yarn is evenly distributed and avoid local stress concentration that leads to roller wear.

[0056] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 6A limiting plate 412 is provided on the limiting shaft 41. The diameter of the limiting plate 412 is larger than the diameter of the through hole 31. The difference in diameter prevents the limiting plate 412 from falling into the through hole 31. When the limiting shaft 41 is located in the through hole 31 and the through groove 411 and the mounting hole 311 are on the same center line, the limiting plate 412 abuts against the top end face of the holder 3. The limiting plate 412 prevents the limiting shaft 41 from being over-inserted into the through hole 31, ensuring consistent installation depth and preventing component misalignment. When the through groove 411 is aligned with the mounting hole 311, the limiting plate 412 contacts the end face of the holder 3, providing intuitive feedback on installation position and simplifying the assembly process.

[0057] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 The bottom of the slide groove 32 is provided with a limiting groove 321, and the bottom of the sliding seat 33 is provided with a protrusion 331 corresponding to the position of the limiting groove 321. The protrusion 331 is embedded in the limiting groove 321 and slides along the limiting groove 321, restricting the sliding seat 33 to move only along a predetermined path, avoiding deviation or jamming, and playing a dual role of guiding and limiting.

[0058] In one embodiment, reference is made to Figures 1-3 A clamping plate 22 is provided on the side of the mounting plate 2 away from the bearing plate 21. By engaging the yarn frame 11 with the clamping plate 22, the mounting plate 2 is installed on the yarn frame 11. The tight fit between the clamping plate 22 and the yarn frame 11 prevents the mounting plate 2 from shaking during high-speed operation and ensures the stability of the yarn guiding system.
