Description

Technical Field

[0001] This utility model relates to the field of knitting machinery parts technology, and more specifically, to a knitting needle anti-snagging structure. Background Technology

[0002] In the textile production process, knitting needles, as the core actuators of knitting equipment, directly affect the fabric forming quality and production efficiency due to their operational stability. Knitting needles must perform the actions of hooking, weaving, and releasing yarn in high-frequency reciprocating motion. However, yarn is easily affected by factors such as tension fluctuations and equipment vibration during the weaving process. If the hooking structure of the knitting needles cannot effectively secure the yarn, it is very easy for the yarn to come loose, leading to defects such as missed stitches and skipped stitches in the fabric. This not only increases the labor costs of subsequent repair processes but may also affect the continuity of production.

[0003] In existing technologies, knitting needles typically use their hook-like structure in conjunction with elastic components to limit the yarn. Common elastic components are often made of ordinary elastic materials, relying solely on their own elastic tension to close and limit the hook-like structure. However, these knitting needles have significant shortcomings in practical use: Firstly, the elastic components are constantly under dynamic conditions of high-frequency stretching and bending, which can easily lead to elasticity decay, breakage, or wear, resulting in a gradual weakening of the yarn-limiting effect and a significant increase in the risk of decoupling. Secondly, some elastic components have a high coefficient of friction or are made of materials with incompatible hardness, which can easily scratch the yarn fibers during frequent contact and friction, leading to yarn breakage or fabric pilling, affecting fabric quality and lifespan. Furthermore, the existing knitting needles lack sufficient coordination between the elastic components and the overall structure, making it difficult to ensure both anti-decoupling effect and smooth yarn guidance, further restricting the stability and efficiency of knitting production. Therefore, we urgently need a knitting needle anti-decoupling structure to solve these problems. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a knitting needle anti-slip structure. Through the synergistic effect of magnetic attraction, locking, and elastic reset, combined with a precise guiding design, it achieves reliable yarn anti-slip and smooth knitting, thereby improving the stability of textile production and the quality of fabrics.

[0005] According to a first aspect of this utility model, a knitting needle anti-slip structure is provided, including a knitting needle and a sleeve rod matched with the knitting needle. The knitting needle includes a needle bar section, a sliding section, a hook section, and a spring-loaded section. The sliding section is integrally formed with the end of the needle bar section, and the hook section is integrally formed with the other end of the needle bar section. The spring-loaded section is hinged to the needle bar section. When the spring-loaded section contacts the end of the hook section, a closed area is formed. A guide is provided on the needle bar section, and a locking member for stabilizing the spring-loaded section is provided at the end of the hook section. The sleeve rod is connected to the needle bar section through an elastic member.

[0006] Optionally, the sleeve rod is provided with a sliding groove adapted to the sliding section, and the inner wall of the sliding groove is symmetrically provided with guide grooves. The sliding section is provided with a protrusion corresponding to the groove. When the protrusion is in the groove, the sliding section slides in the sliding groove and forms a sliding area.

[0007] Optionally, the needle bar section is provided with a flip groove, and a shaft is fixedly connected in the flip groove. The spring tongue section is rotatably connected to the shaft to form a rotating area. The spring tongue section is provided with a first placement groove, and a first magnetic block is fixedly installed in the first placement groove.

[0008] Optionally, the guide includes a triangular block welded to the needle bar section. The triangular block has a long side inclined surface and a short side inclined surface. The long side inclined surface is oriented towards the flip groove, and a second placement groove is formed on the long side inclined surface. A second magnetic block that matches the first magnetic block is fixedly installed in the second placement groove. When the first magnetic block and the second magnetic block are magnetically attracted, an adsorption area is formed.

[0009] Optionally, a guide arc for guiding the yarn direction is provided on the short side inclined surface, and a guide groove is provided on the tongue segment. When in the adsorption zone, the guide groove connects with the end of the guide arc to form a guide path, and the curvature of the guide groove on the side away from the guide arc gradually decreases.

[0010] Optionally, the engaging component includes an engaging groove formed at the end of the hook section, the engaging groove being adapted to the spring section, and elastic sheets being fixedly installed on both inner walls of the engaging groove. When in the adsorption zone, the end of the spring section is inserted into the engaging groove and abuts against the elastic sheets to form an engaging zone.

[0011] Optionally, the elastic element includes a first buckle symmetrically installed on the sleeve rod, a second buckle symmetrically installed on the spring tongue segment, and an elastic rope symmetrically arranged on the sleeve rod, with the two ends of the elastic rope respectively sleeved on the first buckle and the second buckle to form a pulling area for the spring tongue segment.

[0012] Optionally, the elastic rope is made of one of the following materials: polyurethane elastic fiber, polyamide fiber, polyether ester elastomer, or spandex fiber.

[0013] 1. According to one embodiment of this disclosure, the anti-snagging structure of the knitting needle achieves multiple stable positioning of the closed area through a dual fixing design of magnetic adsorption and snap-fit ​​clamping, combined with the stable restoring force provided by the elastic element. This effectively resists the risk of dehooking caused by high-frequency vibration of the equipment and yarn tension fluctuations, significantly reduces fabric defects such as missed needles and skipped stitches, and lowers subsequent repair costs. At the same time, the precise docking design of the spring tongue section and the hook needle section ensures that the contour of the closed area matches the yarn diameter, which not only avoids yarn shaking and displacement, but also prevents squeezing damage, greatly improving the fabric forming quality and production continuity.

[0014] 2. According to one embodiment of this disclosure, the anti-slip structure of the knitting needle, through the seamless connection design of the guide arc and guide groove, combined with the inner wall polishing treatment and gradient curvature optimization, constructs a smooth yarn guiding path, reducing the frictional resistance and jamming phenomenon of the yarn during hooking and knitting. With the selection of low friction material of elastic rope, the yarn fibers are prevented from being scratched, fuzzed or broken. At the same time, each moving part adopts wear-resistant material and precision fit design to reduce wear and stress concentration under high frequency movement, extend the service life of core components such as knitting needles and loopers, and take into account knitting efficiency, yarn quality and equipment operation and maintenance cost control.

Detailed Implementation

[0022] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0023] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0024] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0025] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0026] like Figure 1-4 As shown, a knitting needle 1 anti-slip structure includes a knitting needle 1 and a sleeve 2 that matches the knitting needle 1. The knitting needle 1 includes a needle bar section 11, a sliding section 12, a hook section 13, and a spring tongue section 14. The sliding section 12 is integrally formed with the end of the needle bar section 11, the hook section 13 is integrally formed with the other end of the needle bar section 11, and the spring tongue section 14 is hinged to the needle bar section 11. When the spring tongue section 14 contacts the end of the hook section 13, a closed area is formed.

[0027] Here, each section of the knitting needle 1 is manufactured using an integrated molding process. The needle bar section 11 serves as the core support structure, and its material is high-strength alloy steel to ensure that the knitting needle 1 has sufficient structural rigidity and fatigue resistance during high-frequency reciprocating motion, thus preventing bending or breakage due to long-term stress. The connection between the sliding section 12 and the needle bar section 11 adopts an arc transition design to reduce stress concentration during the movement process and extend the service life of the knitting needle 1. The hook-shaped structure of the hook section 13 adopts a gradient arc design, and its end is polished into a smooth rounded corner, which facilitates smooth hooking of yarn and avoids sharp edges from scratching the yarn fibers.

[0028] Furthermore, the hinge position of the spring tongue section 14 is set on the side of the needle bar section 11 near the hook needle section 13, ensuring that the spring tongue section 14 can accurately align with the end of the hook needle section 13 when it flips. The contour of the closed area is adapted to the diameter of the yarn, ensuring that the yarn can be stably contained in the closed area without the yarn shaking due to excessively large closed space or being squeezed and damaged due to insufficient space.

[0029] Furthermore, the thickness of the spring-loaded segment 14 is gradually varied along its length. The thickness is greater near the hinge end to ensure structural strength, and less near the free end to improve the flexibility of flipping. This allows the spring-loaded segment 14 to withstand the pushing force of the yarn and the pulling force of the elastic element during opening and closing, while also responding quickly to action commands and avoiding jamming or delay.

[0030] The sleeve rod 2 has a groove 3 adapted to the sliding section 12. The inner wall of the groove 3 is symmetrically provided with grooves 4 for guidance. The sliding section 12 is provided with a protrusion 5 corresponding to the groove 4. When the protrusion 5 is in the groove 4, the sliding section 12 slides in the groove 3 and forms a sliding area.

[0031] Here, the sleeve 2 is injection molded from wear-resistant engineering plastic. The length of its internal groove 3 matches the reciprocating stroke of the needle 1. The inner wall of the groove 3 is polished to reduce the coefficient of friction with the sliding section 12, thereby reducing movement resistance and wear. The symmetrically arranged groove 4 is a long strip structure, and its length direction is consistent with the extension direction of the groove 3. The cross-section of the groove 4 is semi-circular, and the inner wall is smooth and burr-free to avoid scratching or jamming the protrusion 5.

[0032] Furthermore, the protrusion 5 on the sliding section 12 is an integrally molded structure, and its height is slightly less than the depth of the groove 4. The surface of the protrusion 5 is polished to ensure that the protrusion 5 can slide smoothly in the groove 4. At the same time, the gap between the protrusion 5 and the groove 4 is controlled within a reasonable range, which not only ensures the guiding accuracy of the movement of the needle 1, but also avoids the needle 1 from deviating due to excessive gap, or the movement resistance from increasing due to insufficient gap.

[0033] Furthermore, limit structures are provided at both ends of the sliding area to prevent the sliding section 12 from coming out of the groove 3 during movement. The limit structure adopts an elastic buffer design, which can play a buffering role when the needle 1 moves to the end of the stroke, reducing the impact force on the needle 1 and the sleeve 2, while improving the overall structure's movement stability and service life.

[0034] A flip groove 6 is provided on the needle bar section 11, and a shaft 7 is fixedly connected in the flip groove 6. The spring tongue section 14 is rotatably connected to the shaft 7 to form a rotating area. A first placement groove 8 is provided on the spring tongue section 14, and a first magnetic block 9 is fixedly installed in the first placement groove 8.

[0035] Here, the width of the flip groove 6 is matched with the thickness of the spring section 14. When the spring section 14 is fully closed, it can be partially embedded in the flip groove 6 to avoid protruding from the surface of the needle bar section 11 and causing the yarn to snag. The shaft 7 is made of stainless steel and is fixed to the two side walls of the flip groove 6 by interference fit. The surface of the shaft 7 is chrome plated to improve wear resistance and rust prevention, and to ensure that the spring section 14 rotates flexibly.

[0036] Furthermore, the first placement groove 8 is opened on the side of the spring tongue section 14 near the hinge end. The depth and width of the first placement groove 8 are precisely matched with the size of the first magnetic block 9. The first magnetic block 9 uses neodymium iron boron permanent magnets, which are magnetically stable and not easily decayed. The first magnetic block 9 is fixed in the first placement groove 8 with strong adhesive to prevent it from falling off during high-frequency movement.

[0037] Furthermore, the gap in the rotating area is controlled at the micrometer level, which ensures that the spring segment 14 can rotate freely while avoiding wobbling caused by excessive gap. A lubricating layer is provided at the contact point between the spring segment 14 and the shaft 7 to further reduce rotational friction, improve the opening and closing response speed of the spring segment 14, and ensure precise synchronization of the weaving action.

[0038] A guide is provided on the needle bar section 11. The guide includes a triangular block 10 welded to the needle bar section 11. The triangular block 10 has a long side inclined surface 101 and a short side inclined surface 102. The long side inclined surface 101 faces the flip groove 6 and a second placement groove 103 is opened on the long side inclined surface 101. A second magnetic block 104 adapted to the first magnetic block 9 is fixedly installed in the second placement groove 103. When the first magnetic block 9 and the second magnetic block 104 are magnetically attracted, an adsorption area is formed. A guide arc 105 for guiding the yarn direction is provided on the short side inclined surface 102. A guide groove 106 is opened on the spring tongue section 14. When in the adsorption area, the guide groove 106 connects with the end of the guide arc 105 to form a guide path. The curvature of the guide groove 106 on the side away from the guide arc 105 gradually decreases.

[0039] Here, the triangular block 10 is made of the same alloy steel as the needle bar section 11 and is fixed by argon arc welding. The weld is polished to ensure that the surface is smooth and without protrusions to avoid snagging the yarn. The tilt angle of the long side inclined surface 101 is adapted to the angle when the spring tongue section 14 is closed, so that the first magnetic block 9 and the second magnetic block 104 can be precisely aligned and adsorbed to ensure the stability of the adsorption force.

[0040] Furthermore, the guide arc 105 is a smoothly transitioned arc structure. Its curvature is designed according to the diameter and tension characteristics of common yarns, which can guide the yarn to move smoothly along the preset path and avoid the yarn from deviating or tangling during the movement. The position of the second placement groove 103 corresponds to the first placement groove 8. The second magnetic block 104 also uses neodymium iron boron permanent magnets. Its magnetic pole direction is opposite to that of the first magnetic block 9, ensuring that the two can generate a stable attraction force. The formed attraction area can provide a reliable positioning function for the closure of the spring tongue segment 14.

[0041] Furthermore, the inner wall of the guide groove 106 is polished to reduce frictional resistance with the yarn. The curvature of the guide groove 106 on the side away from the guide arc 105 gradually decreases, which can guide the yarn from a dispersed state to gradually converge to the hooking area of ​​the hook section 13, improving the accuracy of yarn hooking. When in the adsorption area, the guide groove 106 and the end of the guide arc 105 are seamlessly connected to form a continuous guide path, avoiding the yarn from getting stuck or damaged at the transition.

[0042] The end of the hook section 13 is provided with a locking member for securing the spring section 14. The locking member includes a locking groove 15 opened at the end of the hook section 13. The locking groove 15 is adapted to the spring section 14. Elastic pieces 16 are fixedly installed on both sides of the inner wall of the locking groove 15. When in the adsorption area, the end of the spring section 14 is inserted into the locking groove 15 and abuts against the elastic piece 16 to form a locking area.

[0043] Here, the depth and width of the locking groove 15 are precisely matched with the free end of the spring tongue segment 14. After the spring tongue segment 14 is inserted into the locking groove 15, it can achieve a tight fit, avoiding gaps that could cause the yarn to come out. The elastic sheet 16 is made of spring steel and is thin to ensure good elastic deformation capability. One end of the elastic sheet 16 is fixed to the inner wall of the locking groove 15 by welding, and the other end is a free end that is inclined inward into the locking groove 15.

[0044] Furthermore, the free end of the elastic piece 16 is provided with a smooth rounded corner to avoid scratching the surface of the spring segment 14. The elastic deformation range of the elastic piece 16 is adapted to the insertion depth of the spring segment 14. When the spring segment 14 is inserted into the locking groove 15, the elastic piece 16 is squeezed to generate an elastic recovery force, which forms a lateral clamping force on the spring segment 14 to ensure a stable engagement.

[0045] Furthermore, the interlocking area and the adsorption area work together, with the adsorption force providing initial positioning for the closure of the spring tongue segment 14, and the clamping force of the interlocking area further enhancing the fixing effect. This double protection prevents the spring tongue segment 14 from accidentally opening during the weaving process due to equipment vibration or yarn tension fluctuations. At the same time, the elastic design of the elastic sheet 16 allows the spring tongue segment 14 to smoothly disengage from the interlocking groove 15 when it opens, without generating excessive resistance.

[0046] The sleeve rod 2 is connected to the needle bar section 11 by an elastic element. The elastic element includes a first buckle 17 symmetrically installed on the sleeve rod 2, a second buckle 18 symmetrically installed on the spring tongue section 14, and an elastic rope 19 symmetrically arranged on the sleeve rod 2. The two ends of the elastic rope 19 are respectively sleeved on the first buckle 17 and the second buckle 18 to form a pulling area for the spring tongue section 14.

[0047] Here, the first buckle 17 and the second buckle 18 are both made of stainless steel and are fixed to the outer wall of the sleeve rod 2 and the side of the spring tongue section 14 respectively by welding. The buckle is designed as a ring to facilitate the putting on and taking off of the elastic rope 19. At the same time, the ring structure can prevent the elastic rope 19 from falling off during the movement.

[0048] Furthermore, the elastic cords 19 are symmetrically arranged on both sides of the knitting needle 1 to ensure balanced tension on the spring section 14 and prevent the spring section 14 from flipping or shifting due to excessive tension on one side. The tension in the pulling area is adjusted by the elastic coefficient and initial tension of the elastic cords 19, which can provide auxiliary tension for opening the spring section 14 and reliable restoring force when closing, while preventing damage to the yarn or spring section 14 due to excessive tension.

[0049] Furthermore, wear-resistant sleeves are provided at the contact points between the elastic cord 19 and the first buckle 17 and the second buckle 18 to reduce wear on the elastic cord 19 during high-frequency stretching and friction, and extend the service life of the elastic cord 19; the overall structural design of the elastic component does not affect the reciprocating motion of the knitting needle 1 and the guiding path of the yarn, ensuring that the components work together without interference.

[0050] The elastic rope 19 is made of one of the following materials: polyurethane elastic fiber, polyamide fiber, polyether ester elastomer, or spandex fiber.

[0051] The selected materials all possess excellent elastic recovery properties, enabling them to quickly return to their original shape under high-frequency stretching and bending conditions, avoiding elastic decay and ensuring the tensile stability of the stretching zone; at the same time, the surface of these materials is smooth and has a low coefficient of friction, so they will not scratch the yarn fibers when in contact with the yarn, effectively protecting the yarn quality.

[0052] Furthermore, polyurethane elastic fibers possess excellent wear resistance and anti-aging properties, making them suitable for high-speed weaving equipment; polyamide fibers have high strength and can withstand greater tensile forces, making them suitable for roving weaving scenarios; polyether ester elastomers have good elastic memory and high reset accuracy, making them suitable for working conditions requiring high weaving precision; spandex fibers have a large stretch ratio, can adapt to large-angle flipping of the 14-section spring, and have a wide range of applications.

[0053] Furthermore, the selected materials all possess certain temperature resistance properties, enabling them to adapt to the temperature environment during the operation of textile equipment. This prevents the materials from hardening, becoming brittle, or softening due to temperature changes, ensuring that the elastic rope 19 maintains stable performance during long-term use and does not affect the overall working effect of the anti-disengagement structure of the knitting needle 1.

[0054] In this invention, after the textile equipment is started, the knitting needle 1 performs high-frequency reciprocating linear motion under the drive of the equipment transmission mechanism. Its sliding section 12 forms a sliding fit with the symmetrical groove 4 on the inner wall of the sliding groove 3 inside the sleeve rod 2 through the protrusion 5 on its surface, and precisely guides the movement along the sliding area to avoid deviation or jamming during the movement of the knitting needle 1. When the knitting needle 1 feeds towards the yarn side, the yarn first contacts the guide arc 105 of the inclined surface 102 of the short side of the triangular block 10 under the action of knitting tension. Under the guidance of the curved surface of the guide arc 105, it moves along the preset path until it abuts the entrance of the guide groove 106 of the spring tongue section 14. At this time, the yarn is under continuous tension. Under the combined action of the inertia of the needle 1 and the feed, a lateral thrust is applied to the spring section 14 along the arc direction of the guide groove 106. At the same time, the elastic rope 19 on the sleeve rod 2 applies an auxiliary pulling force in the same direction through the transmission structure formed by the first buckle 17 and the second buckle 18 on the spring section 14. The thrust and pulling forces work together to push the spring section 14 outward. The spring section 14 rotates counterclockwise around the shaft 7 fixed in the rotating groove 6 in the rotating area. The elastic rope 19 is stretched and stores elastic potential energy as it rotates. At the same time, the first magnetic block 9 on the spring section 14 disengages from the second magnetic block 104 on the inclined surface 101 of the long side of the triangular block 10. In the magnetic attraction state, after the spring-loaded section 14 is fully open, the yarn smoothly enters the hook-taking working area of ​​the hook section 13 along the extension direction of the guide groove 106. Once the yarn has fully entered the hook-taking working area and completed the winding action, the lateral thrust of the yarn on the spring-loaded section 14 disappears, and the elastic rope 19 releases its elastic restoring force. This, together with the magnetic attraction forces of the first magnetic block 9 and the second magnetic block 104, forms a synergistic restoring force, driving the spring-loaded section 14 to rotate clockwise around the shaft 7 and close. The free end of the spring-loaded section 14 is precisely inserted into the engaging groove 15 at the end of the hook section 13, forming an elastic abutment with the elastic plates 16 on both sides of the engaging groove 15, creating a stable engaging area. Together with the hook section 13, they form a closed area, reliably confining the yarn within the closed area and completely preventing the unhooking phenomenon caused by equipment vibration and tension fluctuations during the knitting process. After a single knitting action is completed, the knitting needle 1 moves in the reverse direction to reset under the drive of the transmission mechanism. The driving force applied by the transmission mechanism overcomes the magnetic attraction force of the first magnetic block 9 and the second magnetic block 104, the tension of the elastic rope 19, and the elastic clamping force of the elastic sheet 16, causing the spring tongue section 14 to rotate counterclockwise around the shaft rod 7. The locking area is released, the closed area is opened, the knitted yarn is separated from the hook section 13, the knitting needle 1 returns to the initial position, and enters the next reciprocating knitting cycle.
