Description

Technical Field

[0001] This invention relates to the field of textile technology, and more particularly to an irregularly shaped ribbing, its weaving method, and sock-like shoes. Background Technology

[0002] The shape of the ribbing in existing sock knitting machines is limited by the machine itself. Ribbing knitting typically uses at least two yarns: one is the backing yarn, which provides elasticity and is not visible on the surface of the ribbing. This backing yarn is also used as the starting yarn for weaving anti-slip loops and is actively fed by an elastic motor to prevent the ribbing from breaking at the beginning. The remaining yarn is the face yarn, which is passively fed by the shuttle. During normal operation, the backing yarn passes through the feed roller on the elastic motor, which feeds it into the knitting mechanism at a set speed for the loop-forming parts to knit. The needle cylinder rotates forward with the feed roller to knit the ribbing. The resulting ribbing is usually a single, straight cylindrical shape. Although the shape of the ribbing can be changed by adjusting the set feed speed of the elastic motor (i.e., changing the ratio of the feed speed of the backing yarn to the face yarn), this only changes the size of the ribbing, such as creating a flared ribbing that is narrow at the top and wide at the bottom. The shape of the ribbing is limited, and irregular ribbing shapes cannot be knitted.

[0003] Existing irregular ribbing is usually made of multiple knitted blocks spliced ​​together. Patent application publication number CN109736001A discloses a knitted ribbing for an integrated shoe and its knitting process. Although it discloses an integrally formed irregular ribbing, it only uses elastic yarn for the anti-slip loops. The yarn is actively fed by an elastic band motor. When knitting the beginning, the elastic band motor stops rotating, and only the yarn shuttle is passively fed. The needle cylinder knits in both forward and reverse directions to form the irregular ribbing. This ribbing only uses elastic yarn for the anti-slip loops, and the ribbing has the problem of poor elasticity.

[0004] The main reason why the cylinder cannot perform alternating forward and reverse knitting when the elastic motor actively feeds yarn is that during the alternating forward and reverse rotation of the cylinder, the yarn feeding wheel of the elastic motor keeps feeding yarn. The yarn fed by the yarn feeding wheel will bend and pile up outside the knitting mechanism, forming entanglement or entanglement with other yarns. In some cases, the yarn may even become wrapped around the yarn feeding wheel, causing the yarn to break and the yarn feeding wheel to be unable to rotate, thus preventing the ribbing from continuing to knit.

[0005] The existing tension adjustment structure for back-hanging yarn, as seen in authorized patent number CN217947224U, is a constant tension conveying device for elastic bands. It is designed to solve the problem of tension adjustment of elastic yarns during the conveying process. However, the adjustment is passive, the yarn tension (yarn length) is limited, and the tension adjustment is uncontrollable. It is usually located before the elastic band motor to adjust the yarn tension when the yarn enters the elastic band motor from the bobbin. It cannot effectively solve the problem that the yarn will bend and accumulate outside the weaving mechanism and become entangled when the yarn feeding wheel keeps feeding the yarn. Summary of the Invention

[0006] Therefore, it is necessary to provide a non-standard rib to solve the problem of poor elasticity in existing non-standard ribs.

[0007] To achieve the above objectives, the present invention provides a shaped ribbing, wherein the ribbing is woven from at least a plurality of yarns, one of which is an elastic yarn; the elastic yarn and other yarns are woven synchronously to form the backing yarn and face yarn at various positions of the ribbing; the ribbing includes a ribbing body, the upper end of which at least partially has a shaped portion; the shaped portion is formed by alternating forward and reverse weaving of the elastic yarn and other yarns.

[0008] Furthermore, the irregular part is a front pull part located at the front end of the screw mouth and / or a rear pull part located at the rear end of the screw mouth.

[0009] Furthermore, the upper end of the slub also includes an anti-slip coil, which is formed by separately feeding elastic yarn into the woven section.

[0010] A sock-like shoe, employing the aforementioned irregularly shaped ribbing, the sock-like shoe including a ribbing unit, the ribbing unit being an irregularly shaped ribbing.

[0011] A knitting process for irregular ribbing, wherein the irregular ribbing is knitted using a sock knitting machine, the elastic yarn is fed by an active yarn feeding mechanism, and then fed into the knitting mechanism after passing through a tensioning mechanism; other yarns are fed into the knitting mechanism by a passive yarn feeding mechanism.

[0012] Special-shaped section: Elastic yarn and other yarns are knitted by the needle cylinder of the knitting mechanism through forward and reverse knitting directions. The needle cylinder rotates along both sides of the special-shaped section. During the rotation of the needle cylinder, the active yarn feed of the elastic yarn is decelerated.

[0013] Ribbed body: Elastic yarn and other yarns are formed by the forward rotation of the needle cylinder of the knitting mechanism.

[0014] Furthermore, when knitting the irregular section at the upper end of the ribbing, during the cylinder rotation, the yarn feeding of the active yarn feeding mechanism is reduced to 0-5 mm / s.

[0015] Furthermore, the elastic yarn is fed into the weaving mechanism via an active yarn feeding mechanism through four No. 5 shuttles; other yarns are fed into the weaving mechanism via passive yarn feeding mechanisms through three No. 3 shuttles, three No. 4 shuttles, two No. 2 shuttles, and one No. 2 shuttle.

[0016] Furthermore, the tensioning mechanism includes a first tensioning structure, which includes a first fixed seat, a first support, a second support, a tension plate, and a yarn guide rod. The first support and the second support are sequentially arranged on one side of the first fixed seat along the length of the first fixed seat. A fixed rod passes through the first support, and the tension plate is mounted on the fixed rod. The yarn guide rod passes through the second support.

[0017] Furthermore, the tensioning mechanism also includes a second tensioning structure, which includes a second fixed seat, a cylinder, a push plate, a spring, and a main shuttle; the second fixed seat is vertically fixed to the other side of the first fixed seat; the cylinder is located at one end of the second fixed seat corresponding to the first support, and the telescopic rod of the cylinder extends and retracts toward the other end of the second fixed seat; one end of the push plate is connected to the end of the telescopic rod of the cylinder, and the other end abuts against one end of the main shuttle; one end of the spring is fixed to the second fixed seat, and the other end is connected to one end of the main shuttle; the other end of the main shuttle has a yarn guide hole, and the two sides of the main shuttle are located between the main shuttle guide posts fixed to the second fixed seat.

[0018] Furthermore, the cylinder is controlled to extend and retract by a solenoid valve.

[0019] Unlike existing technologies, the above-mentioned technical solution weaves at least part of the upper part of the ribbing into an irregular shape, which allows for unrestricted ribbing shape design and enriches the diversity of ribbing. The entire ribbing is woven with elastic yarn and other yarns together, providing elasticity and adaptability, allowing the ribbing to fit closely to the skin and ensuring it does not slip during wear. It effectively wraps and fixes the ribbing to the skin, while preventing the irregular part from turning outward or wrinkling during wear. The irregular part is formed by alternating forward and reverse weaving of elastic yarn and other yarns, making the entire ribbing integrally formed without splicing, resulting in good integrity. This avoids loosening or breakage at splicing points, improves the stability and durability of the ribbing, and also makes the ribbing more aesthetically pleasing. Attached Figure Description

[0040] See Figures 1 to 9 As shown, the present invention provides a non-circular ribbed rib, wherein at least part of the upper end of the ribbed rib body 102 is a non-circular portion 101, which allows for unrestricted shape design of the ribbed rib 10 and enriches the diversity of the ribbed rib 10. The entire ribbed rib 10 is woven together with elastic yarn and other yarns to provide elasticity and adaptability, allowing the ribbed rib 10 to fit closely to the skin, ensuring that it will not slip during wear and can effectively wrap and fix it to the skin. At the same time, it prevents the non-circular portion 101 from turning outward or wrinkling during wear. The non-circular portion 101 is formed by alternating forward and reverse weaving of elastic yarn A and other yarns, which allows the entire ribbed rib 10 to be integrally formed without splicing, with good integrity, avoiding loosening or breakage at splicing points, improving the stability and durability of the ribbed rib 10, and making the ribbed rib 10 more aesthetically pleasing.

[0041] See Figure 1 As shown, to better understand the present invention, the following provides a specific structure of an irregularly shaped rib. An irregularly shaped rib 10 is woven from at least a plurality of yarns, one of which is an elastic yarn A; the elastic yarn A and other yarns are woven synchronously to form the backing yarn and face yarn at various positions of the rib 10; the rib 10 includes a rib body 102, the upper end of which at least partially has an irregularly shaped portion 101; the irregularly shaped portion 101 is formed by alternating forward and reverse weaving of the elastic yarn A and other yarns.

[0042] The aforementioned backing yarn refers to the yarn that is not exposed on the surface of the rib 10, but is hidden inside the rib 10, giving the rib 10 elasticity. It is woven from elastic yarn A. The aforementioned face yarn refers to the yarn exposed on the surface of the rib 10, used for skin contact and appearance display. The face yarn of the rib 10 can be woven with other yarns to create the desired pattern for appearance display. During the weaving process, different weaving strategies can be used for different parts of the face yarn of the rib 10. In some parts, multiple different yarns can be used to form the face yarn, in some parts, multiple identical yarns can be used, and even in some parts, a single yarn can be used. Of course, the weaving strategy can be the same for all parts. That is, in some embodiments, the entire face yarn of the rib 10 is woven with multiple different yarns; in some embodiments, the entire face yarn of the rib 10 is woven with multiple identical yarns; and in some embodiments, the entire face yarn of the rib 10 is woven with a single yarn. The aforementioned irregularly shaped portion 101 can be convex upwards or concave downwards. The convex and concave shapes can be regular shapes such as arcs or polygons, or they can be irregular shapes. It is formed by weaving elastic yarn A together with other yarns, thus forming the backing yarn and face yarn of the irregularly shaped portion 101. There can be multiple irregularly shaped portions 101, or just one. Multiple irregularly shaped portions 101 can have the same shape or different shapes. It should be noted that the entire rib 10 is woven as a single piece, and the irregularly shaped portion 101 is part of the rib 10. The weaving strategy of the irregularly shaped portion 101 is the weaving strategy of the rib 10.

[0043] It should be noted that the rib 10 described in this embodiment can be either a single rib 10 structure or a double rib 10 structure. When the rib 10 is a double rib 10 structure, the rib body 102 includes an inner rib 10 and an outer rib 10. In some embodiments, the double rib 10 structure is formed by folding inward, that is, during weaving, the inner rib 10 is located above the outer rib 10. At this time, at least a portion of the irregular portion 101 is located at the lower end of the inner rib 10, and at least a portion of the irregular portion 101 is located at the upper end of the outer rib 10. The upper end of the inner rib 10 has a starting opening, and the lower end of the outer rib 10 has a binding opening. The inner rib 10 is folded inward. The starting opening and the binding opening are connected to form a double-ribbed 10 structure. In some embodiments, the double-ribbed 10 structure is formed by folding outwards. That is, during weaving, the outer ribbed 10 is located above the inner ribbed 10. At this time, at least a portion of the irregularly shaped portion 101 is located at the upper end of the inner ribbed 10, and at least a portion of the irregularly shaped portion 101 is located at the lower end of the outer ribbed 10. The lower end of the inner ribbed 10 has a binding opening, and the upper end of the outer ribbed 10 has a starting opening. The inner ribbed 10 is folded outwards, and the starting opening and the binding opening are connected to form a double-ribbed 10 structure. The positions of the irregularly shaped portions 101 of the inner ribbed 10 and the irregularly shaped portions 101 of the inner ribbed 10 can be symmetrically arranged at the folding points or asymmetrically arranged to form a layered pattern. The shapes of the irregularly shaped portions 101 at the lower end and the irregularly shaped portions 101 at the upper end of the inner ribbed 10 can be the same or different, depending on the design of the ribbed 10 shape, making the shape of the ribbed 10 more diverse.

[0044] See Figure 2As shown, the aforementioned irregular part 101 diversifies the shape design of the ribbed 10 and can be applied to certain products, such as socks and socks. When designed in certain specific positions, it also has some practical functions. Taking the direction when wearing the ribbed as the reference, the direction where the toes are located is the front end, the direction of the heel is the rear end, the two sides corresponding to the sole of the foot are the left and right ends, the direction of the sole of the foot is the lower end, and the direction of the instep is the upper end. The irregular part 101 at the upper end of the ribbed body 102 is the front pull part 1011 located at the front end of the ribbed 10 and / or the rear pull part 1012 located at the rear end of the ribbed 10. In some embodiments, the irregular portion 101 of the cuff 10 is positioned at the front end, forming a front pull portion 1011 at the front end of the cuff 10. This front pull portion 1011 makes it easier for the foot to enter the sock / sock, providing a point of leverage, increasing the area of ​​force application on the cuff 10, and increasing the friction of pulling the cuff 10, thus preventing slippage during wear. Only a small pulling force is needed to insert the foot into the sock / sock. In other embodiments, the irregular portion of the cuff 10 is positioned at the rear end, forming a rear pull portion 10 at the rear end of the cuff 10. 12. The rear pull portion 1012 makes it easier for the heel to be put into the sock-shoe or sock, providing a force application point for the sock-shoe or sock, increasing the force application area of ​​the fingers on the cuff 10, increasing the friction of pulling the cuff 10, and preventing slippage when wearing. Only a small pulling force is needed to put the heel into the sock-shoe or sock. In some embodiments, there is a front pull portion 1011 at the front end of the cuff 10 and a rear pull portion 1012 at the rear end of the cuff 10, so that the cuff 10 has the advantages of the above two embodiments, making it easier for the foot to be put into the sock-shoe or sock.

[0045] The upper end of the rib 10 also includes an anti-slip loop, which is separately fed in and woven from elastic yarn A. The anti-slip loop forms the beginning of the rib 10, preventing the rib 10 from breaking at the beginning, thus enhancing its durability. It is typically woven from elastic yarn (this yarn does not specifically refer to the elastic yarn A used as the backing yarn, but rather to any elastic yarn). The anti-slip loop and the backing yarn share the same elastic yarn A, allowing for a tighter bond between the anti-slip loop and the rib 10, reducing the number of loose threads on the rib 10, resulting in good overall integrity and contributing to improved strength, stability, and durability of the rib 10.

[0046] See Figure 3 and Figure 6 As shown, the present invention also provides a knitting process for irregular ribbing, which is used to knit the above-mentioned irregular ribbing. It is knitted by a sock machine. Elastic yarn A is fed through an active yarn feeding mechanism 70, and then fed into the knitting mechanism 90 after passing through a tensioning mechanism 80; other yarns are fed into the knitting mechanism 90 through a passive yarn feeding mechanism.

[0047] Shaped section 101: Elastic yarn A and other yarns are knitted by the needle cylinder of the knitting mechanism 90 through forward and reverse knitting directions. The needle cylinder rotates along both sides of the shaped section 101. During the rotation of the needle cylinder, the active yarn feed of elastic yarn A is decelerated.

[0048] The rib body 102 is formed by knitting elastic yarn A and other yarns through the forward rotation of the needle cylinder of the knitting mechanism 90.

[0049] The aforementioned active yarn feeding mechanism 70 refers to a mechanism that actively feeds yarn into the working area of ​​the knitting mechanism 90 during the spinning or knitting process through a mechanical device or control system. This mechanism can automatically control the yarn supply speed and tension to ensure a stable yarn supply, thereby improving production efficiency and product quality, such as an elastic band motor. The aforementioned passive yarn feeding mechanism refers to a mechanism where the yarn is naturally fed into the working area of ​​the knitting mechanism 90 by gravity or tension during the spinning or knitting process, such as a yarn shuttle or yarn guide. The aforementioned tensioning mechanism 80 is located between the active yarn feeding mechanism 70 and the knitting mechanism 90. It is a device or system used to adjust, maintain, or increase yarn tension, ensuring that the yarn maintains an appropriate tension state during its feeding into the working area of ​​the knitting mechanism 90. This prevents the yarn from bending, piling up, becoming entangled, or getting tangled with other yarns, or even from getting wrapped around the active yarn feeding mechanism 70 (such as the yarn feeding wheel of an elastic band motor). The aforementioned tensioning mechanism 80 can be either active or passive. Passive adjustment is adaptive adjustment based on the yarn tension, while active adjustment typically allows for active control and adjustment of the yarn tension as needed.

[0050] Elastic yarn A is fed through active yarn feeding mechanism 70, and then through tensioning mechanism 80 before being fed into knitting mechanism 90. Elastic yarn A and other yarns are knitted into the irregular section 101 by the needle cylinder of knitting mechanism 90 through forward and reverse knitting directions. The needle cylinder rotates along both sides of irregular section 101. During the rotation of the needle cylinder, active yarn feeding mechanism 70 decelerates to reduce the length of elastic yarn A bending and piling outside knitting mechanism 90, reducing the possibility of yarn crossing and entanglement, and reducing the risk of yarn knotting. After adjustment by tensioning mechanism 80, elastic yarn A is made straight and does not entangle with other yarns. It is fed into knitting mechanism 90 under a certain tension, which can make the rib 10 have a more uniform and flat knitting structure, ensuring the quality and appearance of rib 10. At the same time, the irregular part 101 can also be woven with the elastic yarn A of the active yarn, ensuring that the irregular part 101 and the rib body 102 have the same backing yarn, ensuring the elasticity of the irregular part 101, and the rib 10 has good overall integrity, which helps to improve the strength, stability and durability of the rib 10.

[0051] During cylinder rotation, it is preferable to reduce the yarn feed rate of the active yarn feeding mechanism 70 to 0-5 mm / s. A yarn feed speed of 0-5 mm / s ensures greater yarn stability during cylinder rotation, guaranteeing that the length of yarn fed (the length of the pile) during rotation remains within the adjustment range of the tensioning mechanism 80. This reduces yarn tension fluctuations, improves the uniformity of the ribbing 10, and enhances its quality. Despite the reduced feed speed, maintaining a stable yarn supply during cylinder adjustment minimizes downtime and increases production efficiency. The specific yarn feed deceleration range should be determined based on actual conditions and equipment requirements. Different types of machines and elastic yarn A may require different yarn feed deceleration ranges; therefore, adjustments should be made based on experience and experimental results during actual operation.

[0052] See Figures 7-9As shown, the tensioning mechanism 80 described above is a passive adjustment structure in some embodiments, which adaptively adjusts according to the tension of the elastic yarn A. For example, the present invention provides a first tensioning structure, which includes a first fixed seat 8011, a first support 8012, a second support 8013, a tension plate 8015, and a yarn guide rod 8016. The first support 8012 and the second support 8013 are sequentially arranged on one side of the first fixed seat 8011 along its length. A fixed rod 8014 passes through the first support 8012, and the tension plate 8015 is mounted on the fixed rod 8014. The yarn guide rod 8016 passes through the second support 8013. When winding the elastic yarn A, the elastic yarn A comes down from the active yarn feeding mechanism 70, passes through the perforation 80151 in the tension plate 8015, and winds down from the back of the yarn guide rod 8016 (corresponding to the position of the first fixed seat 8011), before being fed into the weaving mechanism 90. The tension plate 8015 can apply appropriate tension to the passing elastic yarn A, achieving adaptive adjustment of the elastic yarn A's tension. The yarn guide rod 8016, threaded onto the second support 8013, can guide and position the yarn. The back of the guide rod 8016 allows the yarn to bypass from a specific position, ensuring accurate and stable entry into the weaving mechanism 90, preventing yarn deviation and misalignment during feeding. In practical applications, a first threading plate 8017 can also be installed at one end of the first fixed seat 8011 corresponding to the first support 8012. The elastic yarn A passes through the first threading plate 8017 before entering the tension plate 8015. The first threading plate 8017 guides the path of the elastic yarn A, guiding it orderly into the tension plate 8015, avoiding yarn crossing, tangling, and misalignment, ensuring smooth yarn transmission; similarly, a first threading plate 8017 can also be installed at the second support 8013. A second threading plate 8018 is provided at the other end of a fixed base 8011 corresponding to the second support 8013. The elastic yarn A passes through the perforation 80151 in the tension plate 8015, and then winds down from the back of the guide rod 8016 before passing through the second threading plate 8018. Similarly, the second threading plate 8018 guides the path of the elastic yarn A and guides the elastic yarn A to be fed into the weaving mechanism 90 in an orderly manner, avoiding the crossing, entanglement and misalignment of the elastic yarn A during the conveying process, and ensuring the smooth transmission of the yarn.

[0053] In some embodiments, the tensioning mechanism 80 described above is an active adjustment structure, while a passive adjustment structure actively adjusts according to the tension of the elastic yarn A. As provided in this invention, a second tensioning structure is included, comprising a second fixed base 8021, a cylinder 8022, a push plate 8023, a spring 8025, and a main shuttle 8024. The cylinder 8022 is located at one end of the second fixed base 8021, and the telescopic rod of the cylinder 8022 extends and retracts toward the other end of the second fixed base 8021 (i.e., forming an angle with the direction in which the elastic yarn A is fed into the weaving mechanism 90). One end of the push plate 8023 is connected to the end of the telescopic rod of the cylinder 8022, and the other end abuts against one end of the main shuttle 8024. One end of the spring 8025 is fixed to the second fixed base 8021, and the other end is connected to one end of the main shuttle 8024. The other end of the main shuttle 8024 has a yarn guide hole 80242, and the two sides of the main shuttle 8024 are located between the main shuttle guide posts 80241 fixed to the second fixed base 8021. When the elastic yarn A is wound, the elastic yarn A comes down from the active yarn feeding mechanism 70, passes through the yarn guide hole 80242 of the main shuttle 8024, and is then fed into the weaving mechanism 90. During operation, the cylinder 8022 extends and retracts to drive the push plate 8023 to move back and forth, which in turn causes the main shuttle 8024, which is against the push plate 8023, to move back and forth, thereby changing the path of the elastic yarn A into the weaving mechanism 90 and changing the angle at which the elastic yarn A is fed into the weaving mechanism 90. At the same time, the cylinder 8022 extends and drives the push plate 8023 to move towards the other end of the second fixed seat 8021, which in turn causes the main shuttle 8024 to move outward, increasing the path length of the elastic yarn A into the weaving mechanism 90 and actively adjusting the tension of the elastic yarn A. To ensure more precise transmission of the cylinder 8022, a guide groove 80231 can be opened at the corresponding push plate 8023 along the movement direction of the main shuttle 8024. The number of guide grooves 80231 is set according to actual needs. The second fixed seat 8021 is equipped with a push plate guide post 80232 corresponding to the guide groove 80231. When the cylinder 8022 extends and retracts to drive the push plate 8023 to move back and forth, the guide groove 80231 slides on the push plate guide post 80232. Through the cooperation of the guide groove 80231 and the push plate guide post 80232, the push plate 8023 can maintain stable guidance during the movement. This helps to reduce the offset and sway of the push plate 8023 and improve the accuracy and stability of the transmission.

[0054] The tensioning mechanism 80 described above includes both passive and active adjustment structures in some embodiments. For example, the present invention provides a first tensioning structure and a second tensioning structure. The first tensioning structure includes a first fixed seat 8011, a first support 8012, a second support 8013, a tension plate 8015, and a yarn guide rod 8016. The first support 8012 and the second support 8013 are sequentially arranged on one side of the first fixed seat 8011 along its length. A fixed rod 8014 passes through the first support 8012, and the tension plate 8015 is mounted on the fixed rod 8014. The yarn guide rod 8016 passes through the second support 8013. A first yarn threading plate 8017 is provided at one end of the first fixed seat 8011 corresponding to the first support 8012, and a second yarn threading plate 8018 is provided at the other end of the first fixed seat 8011 corresponding to the second support 8013. The second tensioning structure includes a second fixed seat 8021, a cylinder 8022, a push plate 8023, a spring 8025, and a main shuttle 8024. The second fixed seat 8021 is vertically fixed to the other side of the first fixed seat 8011. The cylinder 8022 is located at one end of the second fixed seat 8021 corresponding to the first support 8012, and the telescopic rod of the cylinder 8022 extends and retracts toward the other end of the second fixed seat 8021. One end of the push plate 8023 is connected to the end of the telescopic rod of the cylinder 8022, and the other end abuts against one end of the main shuttle 8024. One end of the spring 8025 is fixed to the second fixed seat 8021, and the other end is connected to one end of the main shuttle 8024. The other end of the main shuttle 8024 has a yarn guide hole 80242, and the two sides of the main shuttle 8024 are located between the main shuttle guide posts 80241 fixed to the second fixed seat 8021. When the elastic yarn A is wound, it comes down from the active yarn feeding mechanism 70, first passes through the first yarn feeding plate 8017, then through the tension plate 8015, then through the back of the guide rod 8016 and into the second yarn feeding plate 8018, and finally through the yarn guide hole 80242 of the main shuttle 8024 into the weaving mechanism 90. Through the combined adjustment of the passive and active adjustment structures, the tension of the elastic yarn A is controlled and adjusted to maintain a suitable tension, reducing the risk of yarn crossing and tangling, and ensuring that the elastic yarn A is fed straight into the weaving mechanism 90. This results in a more uniform and even weaving structure for the rib 10, guaranteeing the quality and appearance of the rib 10.

[0055] To prevent the main shuttle 8024 from extending or retracting too much, which could cause the tension of the elastic yarn A to exceed its elastic limit and break, an adjusting block 8026 can be rotatably connected above the push plate 8023 in some embodiments. The push plate 8023 has a stop 80233 extending upwards towards the adjusting block 8026 from one end corresponding to the cylinder 8022. Typically, the adjusting block 8026 is an irregular polygon. By adjusting the rotation angle of the adjusting block 8026, the furthest extension position and range of motion of the push plate 8023 can be controlled. The adjusting block 8026 requires the first adjusting bolt 8028 to abut against it, fixing the angle of the rotated adjusting block 8026. The adjusting bolt can be connected to either the first fixed seat 8011 or the second fixed seat 8021. In some embodiments, the upper part of the main shuttle 8024 that abuts against the push plate 8023 can also be designed to have a sloped shape. The lower part of one end of the main shuttle 8024 is connected to the spring 8025, and the upper part abuts against the second adjusting bolt 8027. The second adjusting bolt 8027 can be connected to the first fixed seat 8011 or the second fixed seat 8021.

[0056] The cylinder 8022 can be controlled to extend and retract by a solenoid valve 8029. That is, by controlling the on / off state of the solenoid valve 8029, the extension and retraction of the cylinder 8022 can be achieved. By setting an appropriate on / off state of the solenoid valve 8029, precise control of the extension and retraction of the cylinder 8022 can be achieved. This helps improve production efficiency, reduce manual operation, and ensure the stability and consistency of the cylinder 8022's transmission, thus achieving automated control. Simultaneously, by adjusting the on / off state of the solenoid valve 8029, the extension and retraction speed and force of the cylinder 8022 can be flexibly adjusted. According to different working requirements, the parameters of the solenoid valve 8029 can be adjusted to meet different motion requirements.
