Description

Technical Field

[0001] This utility model belongs to the field of yarn processing technology, specifically relating to a low-friction yarn guide. Background Technology

[0002] The yarn guide is a key loop-forming component in textile machinery. Its core function is to precisely guide the yarn into the knitting needles in weft knitting machines, circular knitting machines, and sock knitting machines, ensuring uniform yarn tension and optimizing the loop-forming process. By adjusting the installation position of the yarn guide (height, front / back, left / right), the yarn feeding angle can be controlled, avoiding problems such as missed needles or needle hook collisions. This component often works in conjunction with needle cylinders, cams, and other components to improve yarn stability and fabric quality.

[0003] Domestic utility model patent application number CN202320949983.8 discloses an anti-spinning yarn guide, specifically relating to the technical field of yarn guiding devices. This utility model includes a body, with a support rod on its outer surface and a fixing device on the outer surface of the support rod. The fixing device includes a locking block, with a protrusion fixedly connected to the outer surface of the locking block, which is fixedly connected to the outer surface of the support rod. A first threaded rod is threadedly connected to the inner wall of the locking block, and an L-shaped block is rotatably connected to the outer surface of the first threaded rod. By setting the locking block, when installing the yarn guide, the locking block can be locked onto the outer surface of the yarn guiding machine rod. Rotating the first threaded rod causes it to move along the inner wall of the locking block, moving the L-shaped block and pressing it against the outer surface of the machine rod, thus fixing the locking block to the outer surface of the yarn guiding machine and fixing the position of the body. Rotating the first threaded rod can loosen the L-shaped block and adjust the position of the locking block and the body. The above-mentioned utility model has the function of being able to move in position. As the core component of the textile equipment that guides the yarn path, the design of the yarn guide to reduce friction has a decisive impact on yarn quality, equipment efficiency and production cost. When the friction of the yarn guide is high, the high friction will directly lead to yarn fuzzing and breakage, which is especially obvious when running at high speed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a low-friction yarn guide, including a mounting frame that is installed with the yarn guiding device, multiple sets of fixed mounting mechanisms fixedly installed on the mounting frame, a yarn guide plate fixedly installed on the top of the fixed mounting mechanism, and a yarn guiding mechanism installed on the yarn guide plate. A soft polishing pad is installed on the yarn guide plate on one side of the yarn guiding mechanism, and the two ends of the soft polishing pad are connected to the yarn guide plate through an adjustment mechanism.

[0005] As a further preferred technical solution of this utility model; the mounting bracket is provided with a through groove, and a snap-fit ​​block is fixedly installed inside the mounting bracket between the through grooves, and snap-fit ​​curved surfaces are fixedly installed on the top and bottom of the snap-fit ​​block.

[0006] A limiting plate for auxiliary installation is provided at the through groove position, and the fastening of the fixed installation mechanism is increased by the snap-fit ​​block.

[0007] As a further preferred technical solution of this utility model; the fixed installation mechanism includes a docking frame and a limiting block fixedly installed at the end of the docking frame in a symmetrical arrangement. The docking frame and the mounting frame are fixedly installed by fixing bolts. The limiting block is respectively engaged and positioned with two sets of the snap-fit ​​curved surfaces. A fixing rod is fixedly installed on the top of the docking frame. The top of the fixing rod is fixedly installed with the yarn guide plate.

[0008] By connecting the docking frame and the mounting frame together, it is convenient to install and use multiple sets of yarn guides.

[0009] As a further preferred technical solution of this utility model, the yarn guiding mechanism includes a yarn guiding wheel, a bearing seat fixedly installed at the bottom of the yarn guiding wheel, and a connecting block fixedly installed at the bottom of the bearing seat. The bottom of the bearing seat and the top surface of the yarn guiding plate are fixedly installed. A curved limiting groove is opened in the inner ring of the yarn guiding wheel, and an arc-shaped groove is opened on the yarn guiding wheel at the position of the outer ring of the curved limiting groove.

[0010] As the yarn passes through the guide wheel and rotates the conductor, the curved limiting groove and arc groove minimize the friction on the yarn, thereby reducing the possibility of fiber breakage or peeling, breakage or fuzzing on the yarn surface due to friction. At the same time, it reduces the wear caused by friction on the yarn and the impact on the overall elasticity of the yarn.

Guide holes are fixedly installed at both ends of the yarn guide plate that are close to the soft polishing pad.

[0012] The yarns introduced and guided by the curved limiting groove can be connected and discharged through the ceramic wire buckle position.

[0013] As a further preferred technical solution of this utility model, the adjustment mechanism includes a movable block inside the guide hole, a rotating screw threaded through the guide hole, and a connecting bearing connecting the rotating screw and the movable block. The other end of the movable block is connected to the inner wall of the guide hole by a spring spring. A guide hole is provided inside the guide hole. The two ends of the soft polishing pad pass through the guide hole and are fixedly installed with the two sets of movable blocks.

[0014] The position of the moving block is adjusted by rotating the rotating screw. When friction reduction is required, the soft polishing pad is adjusted to fit the curved surface limiting groove. When no work is required, the soft polishing pad is moved to the end, without affecting the yarn guiding operation of the yarn guide. Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The soft polishing pad is a non-woven fabric pad with colloidal SiO2 polishing liquid. After the yarn guiding is completed, the non-compliant yarns are arranged in the yarn guide for guiding. During the yarn guiding process, the yarn is positioned by one side of the yarn guide wheel, which drives the yarn guiding mechanism to rotate. On the other side of the yarn guiding mechanism, the soft polishing pad with colloidal SiO2 polishing liquid is applied and polished, thereby increasing the overall smoothness of the curved limiting groove and ensuring a low friction effect during long-term use.

[0017] As the yarn passes through the guide wheel and rotates the conductor, the curved limiting groove and arc groove minimize the friction on the yarn, thereby reducing the possibility of fiber breakage or peeling, breakage or fuzzing on the yarn surface due to friction. At the same time, it reduces the wear caused by friction on the yarn and the impact on the overall elasticity of the yarn. Attached Figure Description

[0024] This specific embodiment is a low-friction yarn guide.

[0025] The utility model mentioned above has the function of being able to move in position. As the core component of the textile equipment that guides the yarn path, the design of the yarn guide to reduce friction has a decisive impact on yarn quality, equipment efficiency and production cost. When the friction of the yarn guide is high, the high friction will directly lead to yarn fuzzing and breakage, which is especially obvious when running at high speed.

[0026] Example 1: Its structural schematic diagram is as follows Figures 1-5 As shown. The low-friction yarn guide includes a mounting frame 1 that is installed with the yarn guiding device, and multiple sets of fixed mounting mechanisms 3 fixedly installed on the mounting frame 1. The mounting frame 1 has through slots 11, and snap-fit ​​blocks 12 are fixedly installed inside the mounting frame 1 between the through slots 11. Snap-fit ​​curved surfaces 13 are fixedly installed on the top and bottom of the snap-fit ​​blocks 12. A limiting plate for auxiliary installation is provided at the position of the through slot 11, and the snap-fit ​​blocks 12 increase the tightness of the fixed mounting mechanism 3. The fixed mounting mechanism 3 includes a docking frame 32 and limiting blocks 33 symmetrically arranged at the ends of the docking frame 32. The docking frame 32 is fixedly installed to the mounting frame 1 by fixing bolts 34. The limiting blocks 33 are respectively snap-fitted and positioned with the two sets of snap-fit ​​curved surfaces 13. A fixing rod 31 is fixedly installed on the top of the docking frame 32, and the top of the fixing rod 31 is fixedly installed to the yarn guiding plate 2. The top of the fixing bolt 34 is provided with a bolt cap 341, and the bolt cap 341 is limited and fixed to the mounting frame 1 at the position of the through slot 11. By connecting the docking frame 32 to the mounting frame 1, it is convenient to install and use multiple sets of yarn guides. It also includes a yarn guide plate 2 fixedly installed on the top of the fixed mounting mechanism 3 and a yarn guide mechanism 4 installed on the yarn guide plate 2.

[0027] The yarn guiding mechanism 4 includes a yarn guiding wheel 41, a bearing seat 43 fixedly installed at the bottom of the yarn guiding wheel 41, and a connecting block 42 fixedly installed at the bottom of the bearing seat 43. The bottom of the bearing seat 43 and the top surface of the yarn guiding plate 2 are fixedly installed. The inner ring of the yarn guiding wheel 41 has a curved limiting groove 412, and the outer ring of the yarn guiding wheel 41 has an arc-shaped groove 411. The yarn guiding wheel 41 is made of ceramic. During the process of the yarn rotating through the yarn guiding wheel 41, the curved limiting groove 412 and the arc-shaped groove 411 minimize the friction on the yarn, thereby reducing the possibility of fiber breakage or peeling, breakage or fuzzing on the yarn surface due to friction. At the same time, it reduces the wear caused by friction on the yarn, which affects the overall elasticity of the yarn. A soft polishing pad 5 is installed on the yarn guiding plate 2 on one side of the yarn guiding mechanism 4. The soft polishing pad 5 is a non-woven fabric pad combined with colloidal SiO2 polishing liquid. After yarn guiding, non-compliant yarns are arranged in the yarn guide for guidance. During the guiding process, the yarn is positioned on one side of the yarn guide wheel 41, which drives the yarn guiding mechanism 4 to rotate. The other side of the yarn guiding mechanism 4 is polished by the soft polishing pad 5, which has been infused with colloidal SiO2 polishing liquid, thereby increasing the overall smoothness of the curved limiting groove 412 and ensuring a low-friction effect during long-term use. The two ends of the soft polishing pad 5 are connected to the yarn guide plate 2 via an adjustment mechanism 6. Positioning blocks 21 are fixedly installed at both ends of the middle position of the yarn guide plate 2, and ceramic wire clips 22 are fixedly installed on the positioning blocks 21 at the corresponding positions of the curved limiting groove 412. Guide holes 23 are fixedly installed at both ends of the yarn guide plate 2 that are close to the soft polishing pad 5. The yarns introduced and guided by the curved limiting groove 412 can be discharged through the ceramic wire clips 22. The adjusting mechanism 6 includes a movable block 61 inside the guide hole 23, a rotating screw 64 threaded through the guide hole 23, and a connecting bearing 62 connecting the rotating screw 64 and the movable block 61. The other end of the movable block 61 is connected to the inner wall of the guide hole 23 by a spring spring 63. A guide hole 23 is provided inside the guide hole 23. The soft polishing pad 5 is fixedly installed at both ends through the guide holes 23 and the two sets of movable blocks 61. By rotating the rotating screw 64, the position of the movable block 61 is adjusted. When friction reduction is required, the soft polishing pad 5 is adjusted to fit the curved limiting groove 412. When no work is required, the soft polishing pad 5 is moved to the end, without affecting the yarn guiding operation of the yarn guide.

[0028] The yarn is guided into the curved limiting groove 412 by the ceramic guide wire buckle 22, and then exits through another set of ceramic guide wire buckles 22 after circling the curved limiting groove 412 once, completing the yarn guiding operation. By docking the docking frame 32 with the mounting frame 1, it is convenient to install and use multiple sets of yarn guides. During the process of the yarn rotating the guide wire through the yarn guide wheel 41, the curved limiting groove 412 and the arc groove 411 minimize the friction on the yarn. By rotating the rotating screw 64, the position of the moving block 61 is adjusted. When it is necessary to reduce friction, the soft polishing pad 5 is adjusted to fit the curved limiting groove 412. When it is not needed, the soft polishing pad 5 is moved to the end, without affecting the yarn guiding operation of the yarn guide. After the yarn guiding is completed, the non-compliant yarns are arranged in the yarn guide for guiding. During the yarn guiding process, the yarn is positioned by one side of the yarn guide wheel 41, which drives the yarn guiding mechanism 4 to rotate. Meanwhile, the other side of the yarn guiding mechanism 4 is polished by a soft polishing pad 5 with infused colloidal SiO2 polishing liquid, thereby increasing the overall smoothness of the curved limiting groove 412 and ensuring a low friction effect during long-term use.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
