Description

Technical Field

[0001] This invention relates to the field of yarn processing machinery technology, and in particular to a yarn guiding and threading mechanism and its method of use for textile yarn processing machinery. Background Technology

[0002] In the development of modern textile industry, various forms of shuttleless looms have emerged, including rapier looms, projectile looms, air-jet looms, water-jet looms, multiphase looms, and magnetic weft-introducing looms. Compared with shuttle looms, shuttleless looms produce fabrics with unparalleled advantages in terms of output, quality, and variety. They have replaced shuttle looms in most weaving fields, and this pace is accelerating, expanding from the textile industries of developed countries to developing countries. From the perspective of international shuttleless loom technology development and the needs of the textile industry, air-jet looms have made rapid progress in terms of high speed, wide width, and serialization. Besides their widespread application in the large-scale cotton textile industry, they are increasingly used in yarn-dyed and jacquard fabrics. Rapier looms, on the other hand, have advantages in terms of adaptability to different fabric types, variety of fabric patterns, and a wider range of suitable fabrics. These two types of looms have become the two most widely used types in the textile industry.

[0003] Traditionally, looms that use yarn for weaving can be divided into two main categories: woven looms and knitted looms. Woven looms include the original shuttle looms and the newer shuttleless looms. Shuttleless looms mainly include rapier looms, air-jet looms, water-jet looms, and rapier looms. Knitted looms are divided into two main categories: warp knitting and weft knitting, with many subcategories within each category.

[0004] In the knitting industry, the development of Chinese weaving machinery products is uneven. Circular knitting machines and warp knitting machines have developed relatively quickly, while flat knitting machines and sock knitting machines have developed relatively slowly, and crochet machines have developed rapidly. Domestically produced circular knitting machines, which are widely used, have a relatively complete range of basic products, including single-jersey and double-jersey circular knitting machines, rib knitting machines, and artificial fur knitting machines. Single-jersey circular knitting machines include four-needle track, terry, weft-inserted, and multi-functional single-jersey machines.

[0005] The specific function varies depending on the type of knitting machine. On a circular knitting machine, the yarn guide, also known as a steel shuttle, serves two purposes: first, it accurately places the yarn onto the knitting needles through its guide holes; second, it strictly controls the movement of the needle tongue to prevent the free-moving needle tongue from closing the needle opening after unwinding, thus ensuring smooth knitting. On a flat knitting machine, the yarn guide moves back and forth along the needle bed with the cam, placing the yarn onto the corresponding needle. On a circular hosiery machine, the yarn guide moves in (lowers) or out (raises) as needed. On a warp knitting machine, the yarn guide needle oscillates between the needles or moves laterally in front of or behind the needles as needed, accurately placing the yarn onto the knitting needles.

[0006] For example, application number 201810097112.1 discloses a yarn guiding device for a flat knitting machine, including a base plate, a yarn guiding pulley, a single yarn detection ring, a short-circuit sensor, an upper lead wire, and a lower lead wire. A metal contact needle is provided on the inner side of the outer wall, and a metal movable push plate is provided between the inner and outer walls. The metal movable push plate and the inner wall form a single yarn channel that allows only a single yarn to pass through. An adjusting shaft is rotatably mounted on the base plate. The yarn guiding pulley, single yarn detection ring, first yarn threading ring, and second yarn threading ring cooperate sequentially to guide the yarn into the knitting mechanism. This invention, through the cooperation of the single yarn detection ring, the metal movable push plate, the metal contact needle, and the short-circuit sensor, promptly issues an alarm and automatically stops the machine when yarn knots or tangles occur, preventing knotted or tangled yarn from entering the textile components. Furthermore, the short-circuit sensor, in conjunction with alarm lights and alarms, accurately and clearly alerts users to equipment problems.

[0007] However, current yarn guiding and threading mechanisms often suffer from poor yarn stability and consistency during the weaving process, unstable tension control, yarn tangling and misalignment, leading to unstable machine operation and resulting in yarn loosening or breakage. Furthermore, the loop-forming mechanism has a complex structure, resulting in a high equipment maintenance rate; the needle heel and needle tip are prone to wear and breakage, leading to high maintenance costs. Summary of the Invention

[0008] The technical problem this invention aims to solve is to improve the stability and consistency of yarn during the weaving process, enhance the stability of tension control, reduce yarn tangling and misalignment, improve the smoothness of the spinning machine operation, and reduce yarn slack or breakage. Furthermore, it simplifies the loop-forming mechanism, reduces equipment maintenance rates, minimizes wear and breakage of the needle heel and needle tip, and lowers maintenance costs.

[0020] A method of using a yarn guiding and threading mechanism for a textile yarn processing machine includes the following steps:

[0021] S1. The yarn passes through the external yarn carrying mechanism, around the yarn reversing support wheel on the tail contour wheel support, enters the yarn passing cone on the tail contour wheel support, and then flows through the yarn reversing support wheel on the end contour wheel support before passing through the yarn passing cone on the end contour wheel support.

[0022] S2. The drive motor drives one of the sets of spindles to rotate. Through the pulley and belt drive, the belt rotates. The belt passes through the bottom of the sliding seat and is fixed by the belt pressure plate. Therefore, the sliding seat moves linearly along the circular guide rail, thereby driving the yarn guiding mechanism to move linearly along the circular guide rail.

[0023] S3. The yarn enters multiple sets of yarn guide rollers through the yarn guide cone on the end contour wheel support and is then passed downward through the guide groove on the drive wheel.

[0024] S4. After passing through the yarn guide roller, the yarn passes through the tensioning wheel guide groove on the tensioning wheel and enters the drive wheel. The tensioning wheel seat is movably connected to the tensioning wheel motor through a screw passing through its interior, which converts the linear motion along the end of the tensioning wheel motor shaft into rotation along the short shaft on the yarn guide roller seat, thereby adjusting the yarn tension.

[0025] The S5, X, Y, and Z axes are connected to an adjustment rod, which allows for slight adjustment of the position of the conformal guide block in the three coordinate directions. After the thread passes through the drive wheel, it enters the thread guide spool and then passes through the thread guide hole. The sinking cylinder moves and, through the movable hinge of the first hinge wall and the second hinge wall, drives the conformal guide block to reach the working position.

[0026] S6. The conformal slider moves linearly along the motor magnetic strip, and the tail of the resilient threading hook is provided with a round head boss that moves in the flexible guide groove, thereby realizing that the spline guide rail on the resilient threading hook moves linearly along the guide sleeve hole.

[0027] S7. When the resilient threading hook moves upward to the top, the return spring is compressed, the yarn-blocking arm disengages from the U-shaped closing groove and from the resilient threading hook. At this time, the conforming guide block moves to this position, and the yarn enters the resilient threading hook. When the conforming slider continues to move forward, the resilient threading hook moves downward under the elastic force of the return spring, and the yarn-blocking arm is restricted by the U-shaped closing groove and hinged to close with the resilient threading hook, completing one threading action.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. By setting up a linear yarn guide drive mechanism, the stability and consistency of the yarn during the weaving process can be ensured, thereby improving production efficiency. Closed-loop control enables high-precision position, speed, and torque control. This control method overcomes the stepper motor's step loss problem, ensuring the accuracy and stability of the motion. Furthermore, the precision of the servo motor drive can be achieved through precise control of electrical parameters (such as voltage and current), resulting in more direct and accurate motion outcomes.

[0030] 2. By setting up a multi-stage yarn guiding and adjusting mechanism, the yarn is guided smoothly from the spindle through various components and finally reaches the fabric or ribbon. At the same time, the multi-stage yarn guiding and adjusting mechanism also helps control the yarn tension, prevents yarn tangling and misalignment, maintains the balance and stability of the spinning machine, and prevents the yarn from loosening or breaking. Additionally, the tension and speed of the spinning machine can be adjusted to adapt to different yarn and fabric requirements.

[0031] 3. By setting up a tensioning wheel and tensioning wheel guide groove, power from the spinning machine is transmitted to the dynamic yarn tension device via electricity, thereby achieving control of yarn tension. In actual production, by adjusting the output power and speed of the motor, the yarn tension can be precisely controlled, thus achieving smooth yarn operation and the production of high-quality textiles.

[0032] 4. By incorporating a shuttle-top yarn-feeding mechanism, the yarn reciprocates along its length during the loop-forming process, weaving the yarn into loops. As the hook moves relative to the yarn, the old loop on the needle bar causes the needle latch to rotate, closing the needle opening and placing the yarn and the old loop on opposite sides of the needle latch. As the needle moves further, the yarn passes through the old loop to form a new loop. This shuttle-top yarn-feeding mechanism simplifies the loop-forming mechanism, reduces redundant movements, lowers manufacturing costs, and reduces equipment maintenance.

[0033] 5. By setting up a double-spring threading hook, the yarn will automatically descend under the force of the spring after passing through, simplifying the equipment mechanism. The hook is simpler in structure and easier to manufacture than the latch needle, and can weave relatively thin fabrics. However, the other looping parts that work with it are more complex.

[0034] 6. By setting round head bosses, conformal sliders, and flexible guide grooves, wear parts are dispersed, service life is extended, and while increasing machine speed, the impact force on the knitting needles by the conformal sliders is reduced, thus reducing damage to the needle heel and needle head.

[0035] 7. By setting up a linear motor magnetic strip and a conformal slider, the system structure is greatly simplified, and the weight and volume are also greatly reduced. This reduces the moment of inertia, improves the dynamic response performance and positioning accuracy, eliminates positioning errors caused by intermediate links, and achieves high positioning accuracy. Since there are no mechanical connections or conversion devices, the linear motor runs smoothly and has extremely low noise.

[0036] 8. By setting wear-resistant blocks, the durability and replaceability of the conformal slider are improved. When wear occurs, it is ineffective to replace the conformal slider; only the wear-resistant blocks need to be replaced, thus reducing maintenance costs. Attached Figure Description

In use, the yarn enters the multiple sets of yarn guide rollers 306 through the thread-passing cone 111 on the end contour wheel support 109 and then passes through the wire groove 311 on the drive wheel 309 and is then passed downward.

[0061] In some embodiments, see Figure 9 , Figure 11The multi-stage yarn guiding adjustment mechanism 3 further includes a tensioning wheel motor base 315, a tensioning wheel motor 316, a tensioning wheel seat 317, a tensioning wheel 318, and a tensioning wheel guide groove 319.

The tensioning wheel 318... The tensioning wheel 318 is movably mounted on the tensioning wheel seat 317 via a bearing. A tensioning wheel guide groove 319 is formed on the outer circumference of the tensioning wheel 318. In use, the yarn passes through the yarn guide roller 306, then around the tensioning wheel guide groove 319 on the tensioning wheel 318 before entering the drive wheel 309. The tensioning wheel seat 317 is movably connected to the tensioning wheel motor 316 via a screw passing through it, converting the linear motion along the shaft end of the tensioning wheel motor 316 into rotation along a short shaft on the yarn guide roller seat 305, thereby adjusting the yarn tension. A multi-stage yarn guiding adjustment mechanism guides the yarn, allowing it to smoothly pass from the spindle through various components and ultimately onto the fabric or ribbon. Simultaneously, the multi-stage yarn guiding adjustment mechanism also helps control the yarn tension, preventing yarn tangling and misalignment, maintaining the balance and stability of the spinning machine, and preventing yarn slack or breakage. Furthermore, the tension and speed of the spinning machine can be adjusted to adapt to different yarn and fabric requirements. By incorporating a tensioning wheel and its guide groove, electrical energy is transmitted from the spinning machine to a dynamic yarn tension device, thereby controlling the yarn tension. In actual production, by adjusting the motor's output power and speed, the yarn tension can be precisely controlled, resulting in smooth yarn operation and the production of high-quality textiles.

[0062] In some embodiments, see Figure 9 , Figure 12The yarn guiding and threading mechanism for the textile yarn processing machine further includes a conformal yarn rewinding mechanism 4.

The Y-axis sliding seat 406 is movably disposed on the Y-axis adjusting seat 404 and moves linearly along the axial direction of the Y-beam adjusting rod 405. The Z-axis adjusting seat 407 is fixedly disposed on the Y-axis sliding seat 406. The Z-beam adjusting rod 408 passes through the X-axis adjusting seat 402 via a threaded connection. The Z-axis adjusting seat 407 is fixedly connected to the Z-axis slide 409. The Z-axis slide 409 is movably mounted on the Z-axis adjusting seat 407 and moves linearly along the axial direction of the Z-beam adjusting rod 408. The cylinder fixing crank arm 410 is fixedly mounted on the Z-axis slide 409. The first hinge wall 411 and the second hinge wall 412 are respectively movably hinged to the upper and lower ends of the cylinder fixing crank arm 410.

In use, the position of the conformal guide block 416 in the three coordinate directions can be slightly adjusted by the adjusting rod movably mounted on it in the X, Y, and Z directions. After the wire passes through the drive wheel 309, it enters the wire guide 417 and then passes through the wire guide hole 418. The sinking cylinder 414 moves and, through the movable hinge of the first hinge wall 411 and the second hinge wall 412, drives the conformal guide block 416 to the working position when it is working.

[0063] In some embodiments, see Figure 15-16The yarn guiding and threading mechanism for the textile yarn processing machine further includes a shuttle top threading mechanism 5. The shuttle top threading mechanism 5 includes a threading valve seat 501, a clearance groove 502, a motion guide groove 503, a U-shaped closing groove 505, a guide sleeve hole 506, a resilient threading hook 507, and a spline guide sleeve 510. The threading valve seat 501 is fixedly mounted on the welding frame 101. The side of the threading valve seat 501 has a clearance groove 502 and a motion guide groove from top to bottom, and its top has multiple sets of U-shaped closing grooves. 505, the bottom surface of the clearance groove 502 has multiple sets of guide sleeve holes 506, corresponding to the U-shaped closed groove 505. Multiple sets of spline guide sleeves 510 are provided, each fixedly installed within a guide sleeve hole 506. Multiple sets of resilient yarn-threading hooks 507 are provided, each movably installed within a spline guide sleeve 510, and can move linearly along the axis of the spline guide sleeve 510. By setting a shuttle-top yarn-threading mechanism, during the loop-forming process, the hook reciprocates along its own length direction, weaving the yarn into a loop. When the hook moves relative to the yarn, it relies on the old loop on the needle bar to rotate the needle tongue, closing the needle opening, so that the yarn under the hook and the old loop are respectively on opposite sides of the needle tongue. As the needle moves further, the yarn passes through the old loop to form a new loop. By setting a shuttle-top yarn-threading mechanism, the structure of the loop-forming mechanism is simplified, redundant movements are reduced, not only lowering manufacturing costs but also reducing equipment maintenance rates. By setting up a double-spring threading hook, the yarn automatically descends under the force of a spring after passing through, simplifying the equipment mechanism. The hook is simpler in structure and easier to manufacture than the latch needle, and can weave relatively thin fabrics, but the other looping parts that work with it are more complex.

[0064] In some embodiments, see Figure 16 See Figure 2 The shuttle top threading mechanism 5 also includes a yarn blocking arm 508 and a return spring 509; the yarn blocking arm 508 is movably hinged to the spring-loaded threading hook 507, a spring support platform 511 is provided in the middle of the spring-loaded threading hook 507, the return spring 509 is movably sleeved on the spring-loaded threading hook 507 and is provided between the top surface of the clearance groove 502 and the spring support platform 511, and a spline guide rail 512 is provided at the lower part of the spring-loaded threading hook 507, which moves linearly along the guide sleeve hole 506;

[0065] In some embodiments, see Figure 15-16The shuttle top threading mechanism 5 also includes a linear motor magnetic strip 514 and a conformal slider 515. The linear motor magnetic strip 514 is fixedly mounted on the bottom surface of the motion guide groove 503, and the conformal slider 515 is movably mounted on the magnetic strip 514, moving linearly along the magnetic strip 514. A flexible guide groove 516 is provided on the upper surface of the conformal slider 515. The tail of the resilient threading hook 507 is provided with a round-headed boss 513, the axis of which is collinear with the center of the flexible guide groove 516. By setting the round-headed boss, conformal slider, and flexible guide groove, wear parts are dispersed, service life is extended, and while increasing machine speed, the impact force on the knitting needle by the conformal slider is reduced, reducing damage to the needle heel and needle head. By setting the linear motor magnetic strip and conformal slider, the system structure is greatly simplified, and the weight and volume are greatly reduced. The moment of inertia is reduced, the dynamic response performance and positioning accuracy are improved, and the positioning error caused by intermediate links is eliminated. The positioning accuracy is high. Since there is no mechanical connection or conversion device, the linear motor runs smoothly and with extremely low noise.

[0066] In some embodiments, see Figure 15-16 The shuttle top threading mechanism 5 also includes wear-resistant blocks 517; two wear-resistant blocks 517 are provided, respectively fixedly disposed on both sides of the conformal slider 515, and the top of the motion guide groove 503 is provided with a motion limiting groove 504, and the two sets of wear-resistant blocks 517 respectively contact the two sides of the motion limiting groove 504; in use, the conformal slider 515 moves linearly along the motor magnetic strip 514, and the tail of the resilient threading hook 507 is provided with a round head boss 513 that moves in the flexible guide groove 516, thereby realizing that the spline guide rail 512 on the resilient threading hook 507 moves linearly along the guide sleeve hole 506. When the resilient threading hook 507 moves upward to the top, the return When the return spring 509 is compressed, the yarn-blocking arm 508 disengages from the U-shaped closing groove 505 and the resilient threading hook 507. At this time, the conformal guide block 416 moves to this position, and the yarn enters the resilient threading hook 507. When the conformal slider 515 continues to move forward, the resilient threading hook 507 moves downward under the elastic force of the return spring 509. The yarn-blocking arm 508 is restricted by the U-shaped closing groove 505 and hinges to close with the resilient threading hook 507, completing one threading action. By setting the wear-resistant block, the durability and replaceability of the conformal slider are improved. When wear occurs, it is ineffective to replace the conformal slider; only the wear-resistant block needs to be replaced, reducing maintenance costs.

[0067] A method of using a yarn guiding and threading mechanism for a textile yarn processing machine includes the following steps:

[0068] S1. The yarn passes through the external yarn carrying mechanism, around the yarn reversing support wheel 110 on the tail contour wheel support 108, enters the yarn passing cone 111 on the tail contour wheel support 108, and then flows through the yarn reversing support wheel 110 on the end contour wheel support 109, and passes through the yarn passing cone 111 on the end contour wheel support 109.

[0069] S2. The drive motor drives one of the sets of spindles 205 to rotate. Through the pulley 206 and belt 207, the belt rotates. The belt 207 passes through the bottom of the sliding seat 203 and is fixed by the belt pressure plate 208. Therefore, the sliding seat 203 moves linearly along the circular guide rail 202, thereby driving the yarn guiding mechanism 1 to move linearly along the circular guide rail 202.

[0070] S3. The yarn enters multiple sets of yarn guide rollers 306 through the yarn guide cone 111 on the end contour wheel support 109 and is then passed downward through the guide groove 311 on the drive wheel 309.

[0071] S4. After passing through the yarn guide roller 306, the yarn passes through the tensioning wheel guide groove 319 on the tensioning wheel 318 and enters the drive wheel 309. The tensioning wheel seat 317 is movably connected to the tensioning wheel motor 316 through a screw passing through its interior, which converts the linear motion along the shaft end of the tensioning wheel motor 316 into rotation along the short shaft on the yarn guide roller seat 305, thereby adjusting the yarn tension.

[0072] The S5, X, Y, and Z axes are connected by an adjustment rod, which allows for slight adjustment of the position of the conformal guide block 416 in the three coordinate directions. After passing through the drive wheel 309, the wire enters the wire guide spool 417 and then passes through the wire guide hole 418. The sinking cylinder 414 moves and, through the movable hinge of the first hinge wall 411 and the second hinge wall 412, drives the conformal guide block 416 to the working position.

[0073] S6. The conformal slider 515 moves linearly along the motor magnetic strip 514. The tail of the resilient yarn threading hook 507 is provided with a round head boss 513 that moves in the flexible guide groove 516, thereby realizing that the spline guide rail 512 on the resilient yarn threading hook 507 moves linearly along the guide sleeve hole 506.

[0074] S7. When the resilient threading hook 507 moves upward to its highest point, the return spring 509 is compressed, and the yarn-blocking arm 508 disengages from the U-shaped closing groove 505 and the resilient threading hook 507. At this time, the conformal guide block 416 moves to this position, and the yarn enters the resilient threading hook 507. When the conformal slider 515 continues to move forward, the resilient threading hook 507 moves downward under the elastic force of the return spring 509, and the yarn-blocking arm 508 is restricted by the U-shaped closing groove 505 and hinged to close with the resilient threading hook 507, completing one threading action.

[0075] Obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.

S4. After passing through the yarn guide roller (306), the yarn passes through the tensioning wheel guide groove (319) on the tensioning wheel (318) and enters the drive wheel (309). The tensioning wheel seat (317) is movably connected to the tensioning wheel motor (316) through a screw passing through its interior, which converts the linear motion along the shaft end of the tensioning wheel motor (316) into rotation along the short shaft on the yarn guide roller seat (305), thereby adjusting the yarn tension. S5. In the three coordinate directions of X, Y, and Z, the X-beam adjusting rod (402) movably set on the X-direction adjusting seat (401), the Y-beam adjusting rod (405) movably set on the Y-direction adjusting seat (404), and the Z-beam adjusting rod (408) movably set on the Z-direction adjusting seat (407) are used to slightly adjust the position of the conformal guide block (416) in the three coordinate directions. After the wire passes through the drive wheel (309), it enters the wire guide spool (417) and then passes through the wire guide hole (418). The sinking cylinder (414) moves and, through the movable hinge of the first hinge wall (411) and the second hinge wall (412), drives the conformal guide block (416) to reach the working position when working. S6. The conformal slider (515) moves linearly along the motor magnetic strip (514), and the tail of the resilient threading hook (507) is provided with a round head boss (513) that moves in the flexible guide groove (516), thereby realizing that the spline guide rail (512) on the resilient threading hook (507) moves linearly along the guide sleeve hole (506); S7. When the resilient threading hook (507) moves upward to the top, the return spring (509) is compressed, and the yarn-blocking arm (508) is released from the restriction of the U-shaped closing groove (505) and the resilient threading hook (507). At this time, the conformal guide block (416) moves to this position, and the yarn enters the resilient threading hook (507). When the conformal slider (515) continues to move forward, the resilient threading hook (507) moves downward under the elastic force of the return spring (509), and the yarn-blocking arm (508) is restricted by the U-shaped closing groove (505) and hinged to close with the resilient threading hook (507), completing one threading action.
