Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and in particular to a high-speed stable yarn feeding and yarn breakage early warning device for warping machines. Background Technology

[0002] Warping machines are crucial equipment in the textile industry, used to wind a certain amount of yarn parallel to a warp beam according to specified lengths and widths, preparing it for subsequent weaving processes. Their efficiency and yarn supply stability directly affect the quality and production schedule of textiles. Yarn supply is the core of warping machine operation, requiring a continuous, uniform, and uninterrupted delivery of yarn to the winding mechanism to meet the stringent requirements of high-speed warping for yarn tension and path. Yarn breakage warnings monitor yarn conditions and promptly issue signals when a breakage occurs, allowing operators to quickly address the issue and reduce downtime losses and defective products caused by yarn breaks.

[0003] Traditional yarn feeding devices have significant shortcomings: one method places the yarn bobbin directly on a support rod, relying on the tension of the yarn winding device to rotate the bobbin and release the yarn. The yarn movement is often perpendicular to the bobbin, making it prone to breakage due to excessive tension. Another method adjusts the position to align the yarn movement horizontally with the bobbin, but with numerous bobbins, maintaining uniform horizontality is difficult, leading to interference with yarn release and similar breakage. Furthermore, traditional warning devices lack precise sensing mechanisms, making it difficult to detect yarn breakage promptly. The yarn feeding process is also cumbersome and unsuitable for warping different quantities of yarn, severely impacting warping efficiency.

[0004] Therefore, this invention proposes a high-speed stable yarn feeding and yarn breakage early warning device for warping machines. An adjustable rotating ball ensures the yarn movement direction is aligned with the yarn bobbin, while a matrix-style threading hole and a progressive threading method reduce interference and yarn breakage. A locking pin and pull rod structure facilitates convenient installation and secure fixation of the yarn bobbin. The coordinated operation of the rotating rod, thread guide ring, and signal rod provides timely warnings of yarn breakage. Ultimately, this achieves stable yarn feeding, convenient operation, and timely detection of yarn breakage during high-speed warping, improving warping efficiency and quality. Summary of the Invention

[0005] Technical problems to be solved: Traditional yarn supply methods are prone to yarn breakage and lack of timely early warning.

[0006] To address the shortcomings of existing technologies, this invention provides a high-speed, stable yarn feeding and yarn breakage early warning device for warping machines, thereby solving the technical problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] High-speed stable yarn feeding and yarn breakage early warning device for warping machines, including yarn feeding assembly and early warning assembly:

[0009] The yarn supply assembly includes:

[0010] The shelf has fixed plates arranged in a 10*10 array.

[0011] The front side of the fixed plate is connected to the base by bolts, and the base is movably connected to the spherical rotating ball via a fixing ring;

[0012] A screw is threaded to one side of the fixed ring, and an extrusion disc is rotatably connected to the end of the screw. A frosted groove is provided at the corresponding position of the rotating ball.

[0013] The outer side of the rotating ball is fixed with a yarn roll rod, and the rod is equipped with a locking pin with spring one and a pull rod with spring two.

[0014] The rack is equipped with multiple sets of cable guide holes;

[0015] The early warning component includes:

[0016] A mounting bracket is provided with a slider, an insertion hole, and a cable pass-through hole.

[0017] A signal rod and a fixed rod are installed in the middle of the fixed frame, and the fixed rod is rotatably connected to a rotating rod with a torsion spring;

[0018] A wire loop is provided at the end of the rotating rod, and the fixed frame is connected to the lifting rod frame;

[0019] The rotating ball can be adjusted to a fixed angle via a screw to ensure that the direction of the yarn roll rod is consistent with the movement trajectory of the yarn; the early warning component detects yarn breakage by contacting / separating the rotating rod with the signal rod.

[0020] In one possible implementation, the rotating ball can rotate between the base and the fixed ring to adjust the extension direction of the yarn roll rod. The screw pushes the extrusion plate to contact the abrasive groove, and the abrasive surface restricts the rotation of the rotating ball so that the yarn roll rod always points to the first thread hole.

[0021] In one possible implementation, the spring pushes the outer end of the locking pin to protrude from the surface of the yarn roll rod to restrict the movement of the yarn bobbin fitted on the outside of the yarn roll rod and prevent it from slipping off; the inclined surface design on the outside of the locking pin facilitates the squeezing of the locking pin to move inward when the yarn bobbin is installed.

[0022] In one possible implementation, pulling the lever can move the extrusion block and the extrusion ramp, forcing the locking pin to move inward so as to remove the yarn bobbin; after releasing the lever, the second spring pushes the extrusion block to reset, and the locking pin is reset under the action of the first spring.

[0023] In one possible implementation, the number of yarn feeding assemblies is determined based on the number of warp yarn rolls, and the yarn passes through the yarn guide hole and the warning assembly in a specific order; when 1000 rolls of yarn require 10 sets of yarn feeding assemblies, a 10 The yarn passes through multiple thread holes and then enters the warning component.

[0024] In one possible implementation, the yarn passes through the first thread guide hole, the thread guide ring, and the other thread guide hole. When winding, the yarn tightens and pulls up the thread guide ring, causing the rotating rod to separate from the signal rod. After the yarn breaks, the rotating rod contacts the signal rod under the action of the torsion spring, breaking the initial state and realizing the early warning.

[0025] In one possible implementation, the rebound force of the torsion spring can push the rotating rod to contact the signal rod, providing an initial triggering force for the yarn breakage warning. Rotating the lifting frame can drive the rotating rod and the thread guide ring to rise, so that the thread guide ring is flush with the thread guide hole, facilitating the yarn threading operation.

[0026] In one possible implementation, the yarn winding sequence at different coordinates on each group of yarn supply components follows the same logic, that is, the yarn of the next group corresponding to the coordinate passes through the threading hole 2 of the previous group corresponding to the coordinate in sequence and then enters the warning component.

[0027] Beneficial effects compared to existing technologies:

[0028] 1. In this solution, the precise alignment of the yarn movement direction with the yarn bobbin is achieved through the cooperation of an adjustable rotating ball and a yarn winding rod. The rotating ball can rotate flexibly between the base and the fixing ring, adjusting the extension direction of the yarn winding rod so that it always points to the first thread hole. In conjunction with the screw, it pushes the extrusion plate to contact the abrasive surface of the abrasive groove at a fixed angle, avoiding the problem of the yarn bobbin being pulled or interfered with by the yarn bobbin due to the direction deviation of the yarn in traditional yarn feeding, reducing the risk of yarn breakage and ensuring the stability of high-speed yarn feeding.

[0029] 2. In this solution, timely warning of yarn breakage is achieved through the sensing and coordination of the rotating rod, the thread guide ring, and the signal rod in the early warning component. When the yarn is taut, the thread guide ring causes the rotating rod to separate from the signal rod. After the yarn breaks, the torsion spring pushes the rotating rod to contact the signal rod, breaking the initial state and triggering the warning. At the same time, the lifting frame facilitates yarn feeding, and multiple sets of early warning components can be adapted to different yarn quantities, ensuring that yarn breakage problems are quickly detected during the warping process and reducing production delays caused by yarn breakage.

[0030] 3. In this solution, the yarn threading path is planned according to the sequence and coordinate numbering of the yarn supply components, achieving orderly yarn management when multiple sets of yarn supply components work together. For example, when 1000 rolls of yarn correspond to 10 sets of yarn supply components, a 10The yarn at (1,1) passes sequentially through a9(1,1)9 to a1(1,1)9 before entering the warning assembly. This hierarchical threading logic avoids tangling and interference between multiple yarns during the yarn supply process, ensuring neatness and order when a large number of yarns are supplied simultaneously. The number of yarn supply assemblies and the threading sequence can be flexibly adjusted according to the number of warping yarns, achieving adaptation to different scale warping needs. For example, when using 5 sets of yarn supply assemblies for 500 rolls of yarn, the yarn at a5(6,3) is threaded in the order of a4(6,3)9→a3(6,3)9→a2(6,3)9→a 1（ The sequential threading of the 6,3)9→early warning components eliminates the need for additional equipment structure adjustments to meet varying production demands, enhancing the device's versatility and practicality. Combined with the matrix arrangement of the thread guide holes and the yarn supply components, precise guidance of the yarn from the supply unit to the early warning components is achieved. Each fixed disc's thread guide hole two forms a dedicated channel with its corresponding yarn roll. The rotating ball adjusts the direction of the yarn roll rod, ensuring the yarn always moves stably along the preset path. This reduces friction and pulling caused by path deviations, further lowering the probability of yarn breakage and guaranteeing the stability of high-speed yarn supply. Attached Figure Description

[0050] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can also be implemented in various different forms, and therefore the present invention is not limited to the embodiments described below. In addition, for the purpose of more clearly describing the present invention, parts not connected to the invention will be omitted from the drawings.

[0051] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0052] Example: Traditional yarn feeding devices typically place the yarn bobbin directly on the support rod of the yarn frame. Yarn feeding is entirely driven by the tension of the yarn winding equipment, which rotates the yarn bobbin on the support rod for spinning. During yarn feeding, the yarn's movement direction is mostly perpendicular to the yarn bobbin, and such tension easily causes yarn breakage, affecting warping efficiency. Another traditional yarn feeding device adjusts the relative position of the yarn frame and the warping machine so that the yarn's movement direction is horizontal to the direction of the yarn bobbin. In this way, the yarn does not need to be fed by pulling the yarn bobbin to rotate. However, since there are many yarn bobbins, it is impossible for them all to be kept at the same level as the warping machine. As a result, during yarn feeding, the yarn is often interfered with by the yarn bobbins themselves, affecting yarn feeding and causing yarn breakage.

[0053] Therefore, this embodiment describes the specific structure of the high-speed stable yarn feeding and yarn breakage early warning device for warping machines. Please refer to [link / reference]. Figures 1 to 17 As shown, the yarn supply and yarn breakage warning device includes a yarn supply assembly, which consists of 10 sets. Each set includes a frame 1, and a set of 10*10 fixed plates 2 are provided on the frame 1. A base 3 is bolted to the front of each fixed plate 2. A spherical rotating ball 4 is rotatably connected to the front of the base 3 through a fixing ring 5. A screw 7 is threaded to one side of the fixing ring 5. An extrusion plate 8 is rotatably connected to the end of the screw 7 near the rotating ball 4. A sanding groove 6 is provided on the side of the rotating ball 4 near the screw 7. Both the sanding groove 6 and the side of the extrusion plate 8 near the sanding groove 6 are sanded.

[0054] A yarn winding rod 9 is fixedly connected to the outside of the rotating ball 4. The screw 7 pushes the extrusion plate 8 to contact the abrasive groove 6, and then the abrasive surface of the two contacts restricts the rotation of the rotating ball 4. When the extrusion plate 8 and the abrasive groove 6 are not in contact, the rotating ball 4 rotates between the base 3 and the fixing ring 5 to adjust the extension direction of the yarn winding rod 9. By adjusting the extension direction of the yarn winding rod 9, the yarn winding rod 9 can always point to the thread hole 27 that needs to be threaded, so that the movement direction of the yarn is in the same straight line as the yarn bobbin. This can avoid the need to pull the yarn bobbin to rotate in order to achieve yarn release, and the yarn release can also avoid the yarn being interfered with by the yarn bobbin itself when the yarn winding rod 9 is not in the same horizontal position as the thread hole 27, which would affect the yarn release and cause yarn breakage.

[0055] The yarn roll rod 9 has a locking pin 10 slidably connected to the inside of the end away from the base 3. A spring 12 is provided between the locking pin 10 and the inside of the yarn roll rod 9. The rebound force of the spring 12 pushes the outer end of the locking pin 10 to protrude from the surface of the yarn roll rod 9. Then, when the yarn bobbin is sleeved on the outside of the yarn roll rod 9, the movement of the yarn bobbin can be restricted by the locking pin 10. Furthermore, when the yarn roll rod 9 is adjusted in direction, such as tilting downwards, the yarn bobbin can also be prevented from slipping off the outside of the yarn roll rod 9.

[0056] The outer side of the locking pin 10 is designed with an inclined surface. With this design, when the yarn bobbin is installed on the outside of the yarn winding rod 9, the inclined surface of the locking pin 10 can be squeezed by the inner wall of the yarn bobbin, thereby squeezing the locking pin 10 to move inward, and then the yarn bobbin can be directly installed on the outside of the yarn winding rod 9.

[0057] Multiple locking pins 10 are provided with pressure grooves 11 on their inner sides. A pull rod 13 is slidably connected to the end of the yarn roll rod 9 away from the base 3. Multiple extrusion blocks 14 are fixedly connected to the end of the pull rod 13 near the inside of the yarn roll rod 9. Extrusion slopes 15 are provided at the joints of the multiple extrusion blocks 14 and the pressure grooves 11. By pulling the pull rod 13, the extrusion blocks 14 are driven to move into the pressure grooves 11. Due to the special design of the slope of the extrusion slope 15, as the extrusion blocks 14 gradually move into the inside of the pressure grooves 11, they also move and force the locking pins 10 to move into the inside of the yarn roll rod 9. When the locking pins 10 are completely moved into the inside of the yarn roll rod 9, the locking pins 10 no longer restrict the movement of the yarn bobbin, and the yarn bobbin can be moved out from the outside of the yarn roll rod 9.

[0058] In addition, a second spring 16 is sleeved on the outside of the pull rod 13. The second spring 16 is located between the inner wall of the extrusion block 14 and the yarn roll rod 9. When the pull rod 13 moves the extrusion block 14 into the interior of the pressure groove 11, the extrusion block 14 and the inner wall of the yarn roll rod 9 squeeze the second spring 16. When the yarn bobbin is removed, the pull rod 13 is released. At this time, the second spring 16 rebounds and pushes the extrusion block 14 to reset. Then the extrusion block 14 and the extrusion inclined surface 15 contact the restriction on the pressure groove 11, and then contact the restriction on the locking pin 10. At this time, the locking pin 10 is also reset under the push of the first spring 12.

[0059] The frame 1 is equipped with multiple cable guide holes 30, arranged in groups of nine (10 x 10 groups), and each group is located on one side of the fixed plate 2. Figure 1 and Figure 14 When there are multiple sets of yarn feeding components, they are arranged sequentially, one after another, and the multiple sets of yarn feeding components are respectively denoted as a1, a2, ..., a... 10 Because the yarn roll rods 9 are arranged in a 10*10 matrix on a single frame 1, such as Figure 2 As shown, each fixed disk 2 can then be assigned a single number, such as a1(1,1), a1(10,9), a5(6,7), etc.; additionally, as Figure 3 As shown, the nine wire holes 2 30 next to each fixed plate 2 are grouped together, and each wire hole 2 30 is also assigned a separate number, such as a1(1,1)1, a1(1,1)2, a1(2,2)1;

[0060] like Figure 1 and 14Assuming a total of 1000 rolls of yarn are being warped, 10 sets of yarn supply components are needed. These 10 sets are arranged sequentially (those closer to the warning component go first, those farther away go last) at certain intervals. During threading, the yarn of a1(1,1) is passed directly through the warning component, while the yarn of a2(1,1) must first pass through a1(1,1)1 before passing through the warning component. Therefore, the passing order of the yarn of a3(1,1) is a2(1,1)2 → a1(1,1)2 → warning component, and the passing order of the yarn of a4(1,1) is a3(1,1)3 → a2(1,1)3 → a1(1,1)3 → warning component, and so on. 10 The yarn passing sequence of (1,1) is a9(1,1)9→a8(1,1)9→a7(1,1)9→a6(1,1)9→a5(1,1)9→a4(1,1)9→a3(1,1)9→a2(1,1)9→a1(1,1)9→early warning component;

[0061] Similarly, the threading sequence of the yarn spool at coordinate (2,2) on each group of yarn supply components is as follows: the yarn at a1 (2,2) passes directly through the warning component; the yarn at a2 (2,2) passes through a1 (2,2)1 → warning component; the yarn at a3 (2,2) passes through a2 (2,2)2 → a1 (2,2)2 → warning component; the yarn at a4 (2,2) passes through a3 (2,2)3 → a2 (2,2)3 → a1 (2,2)3 → warning component, and so on. 10 The yarn passing sequence of (2,2) is a9(2,2)9→a8(2,2)9→a7(2,2)9→a6(2,2)9→a5(2,2)9→a4(2,2)9→a3(2,2)9→a2(2,2)9→a1(2,2)9→early warning component;

[0062] The threading sequence of the yarn spool at coordinate (4, 3) on each yarn supply assembly is as follows: the yarn at a1 (4, 3) passes directly through the warning assembly; the yarn at a2 (4, 3) passes through a1 (4, 3)1 → warning assembly; the yarn at a3 (4, 3) passes through a2 (4, 3)2 → a1 (4, 3)2 → warning assembly; the yarn at a4 (4, 3) passes through a3 (4, 3)3 → a2 (4, 3)3 → a1 (4, 3)3 → warning assembly, and so on. 10 The yarn passing sequence of (4,3) is a9(4,3)9→a8(4,3)9→a7(4,3)9→a6(4,3)9→a5(4,3)9→a4(4,3)9→a3(4,3)9→a2(4,3)9→a1(4,3)9→early warning component;

[0063] Additionally, assuming only 500 rolls of yarn need to be warped, 5 sets of yarn supply components need to be set up. These 5 sets are arranged one by one in sequence at certain intervals. Taking the yarn roll with coordinate (6,3) on each yarn supply component as an example, the yarn of a1 (6,3) passes directly through the warning component. The yarn of a2 (6,3) passes through the warning component in the following order: a1 (6,3)1 → warning component. The yarn of a3 (6,3) passes through the warning component in the following order: a2 (6,3)2 → a1 (6,3)2 → warning component. The yarn of a4 (6,3) passes through the warning component in the following order: a3 (6,3)3 → a2 (6,3)3 → a1 (6,3)3 → warning component. The yarn of a5 (6,3) passes through the warning component in the following order: a4 (6,3)9 → a3 (6,3)9 → a2 (6,3)9 → a1 (6,3)9 → warning component.

[0064] Based on the above, when different numbers of yarn rolls need to be warped, the required number of yarn feeding components and the yarn threading situation between each yarn feeding component can be determined.

[0065] like Figures 8 to 13 As shown, it includes multiple sets of warning components. Each set of warning components is installed on the lifting frame 26 by engaging the slide bar 20 on the warning component with the slot 18 on the lifting frame 26. At the same time, the warning component is locked by engaging the pin 17 with the socket 21 to prevent its position from shifting.

[0066] Each set of early warning components includes a fixed frame 19. Slide strips 20 and insertion holes 21 are provided on both sides of the fixed frame 19. 100 thread-passing holes 27 are opened on the front and rear sides of the fixed frame 19. A signal rod 25 is installed in the middle. A fixed rod 22 is fixedly connected to the middle side near the yarn supply component. 100 rotating rods 23 are rotatably connected to the outside of the fixed rod 22. Torsion springs 24 are provided between the multiple rotating rods 23 and the fixed rods 22. The rebound force of the torsion springs 24 pushes the rotating rods 23 to contact the signal rods 25. A thread-passing ring 28 is fixedly connected to the end of the multiple rotating rods 23 away from the fixed rods 22.

[0067] Ten sets of warning components can be installed on a single lifting frame 26. Of course, the design can be customized according to actual conditions. After the yarn spool undergoes initial combing by the yarn feeding component, such as... Figure 12As shown, each yarn is passed through the thread guide hole 27 on the side near the yarn supply assembly, then through the thread guide ring 28, and finally through the thread guide hole 27 on the other side. There is a contact sensor between the rotating rod 23 and the signal rod 25. When the yarn passes through the thread guide ring 28 and is being wound up, the yarn tension will lift the thread guide ring 28, causing the rotating rod 23 to separate from the signal rod 25. The rotating rod 23 connected to the thread guide ring 28 that has not been threaded will continue to contact the signal rod 25 under the action of the torsion spring 24. The state before winding up after threading is set as the initial state. When a yarn breakage occurs, the rotating rod 23, which is lifted by the yarn, will be rebounded by the torsion spring 24 and contact the signal rod 25 again. In this way, the initial state is broken, thus playing a warning role.

[0068] like Figure 1 and Figure 15 The warning component is matched with the yarn feeding component. The appropriate number of yarn feeding and warning components are selected based on the required number of warping yarn rolls. The specific details of their coordinated use are as follows: Figure 15 As shown ( Figure 15 The left side shows a set of yarn supply components and a set of warning components, which can perform warping work on up to 100 yarn rolls. The right side shows two sets of yarn supply components and two sets of warning components, which can perform warping work on up to 200 yarn rolls. Subsequent yarn supply components are added sequentially to the right, and warning components are added sequentially upwards. If 100 yarn rolls need to be warped, only one set of yarn supply components and one set of warning components are needed. The 100 yarn rolls are passed through the yarn supply components in the order of x-axis 1-10 and then y-axis 1-10, from the left to the right of the warning components. One set of yarn supply components corresponds to one set of warning components.

[0069] If there are more than 100 yarn rolls, such as 200 yarn rolls, first arrange the yarn according to the yarn feeding sequence of the yarn feeding component. At this time, the yarn feeding sequence of the warning component is carried out in the order of bottom to top and left to right. Starting from the yarn in the lower left corner of the yarn feeding component, first pass through the thread hole 27 on the left side of the lower warning component, and then pass the yarn to the right. After the lower warning component is completely fed, upgrade to the upper warning component until the yarn feeding is completed.

[0070] Similarly, for 350 rolls, 540 rolls, etc., first thread the yarn according to the yarn feeding assembly's threading sequence, and then thread it through the warning assembly in the order of bottom to top and left to right to complete the yarn combing work.

[0071] A square-shaped lifting rod frame 26 is rotatably connected to the middle of the fixed frame 19. Multiple rotating rods 23 pass through the lifting rod frame 26. Rotating one side of the lifting rod frame 26 causes the other side to lift up, which in turn drives the rotating rods 23 to lift up. Lifting the rotating rods 23 can drive the thread guide ring 28 to lift up. By lifting the thread guide ring 28, it is made to be flush with the thread guide hole 27, which facilitates the yarn threading work.

[0072] like Figure 16 and Figure 17 As shown, the warning component is also equipped with a combing roller 31. After the yarn passes through the combing roller 31, it is then wound up by the winding device. The rotation of the combing roller 31 relies on the friction of the winding device when winding the yarn. It is fixed by a bracket. The combing roller 31 may have yarn grooves, the number of which depends on the maximum number of yarn rolls that need to be warped. After the yarn passes through the warning component, the combing roller 31 completes the final combing and can then be wound up for use. The height of the combing roller 31 is higher than that of the warning component. The yarn on the warning component is connected to the combing roller 31 in the order from bottom to bottom and from the middle to both sides. The winding order of the yarn on the combing roller 31 is from the middle to both sides. Firstly, the regular winding can avoid interference between yarn bundles. Secondly, winding the yarn in sequence can prevent the yarn bundles from being too loose and affecting the warping effect.

[0073] In summary, the yarn feeding assembly structure consists of 10 sets (more sets can be set, depending on the display; the dimensions of the frame 1 and the number of fixing plates 2 on the frame 1, including the number of thread guide holes 30, can be changed according to the actual situation). Each set includes a frame 1 with 10*10 fixing plates 2. Each fixing plate 2 has a base 3 bolted to its front side. The front side of the base 3 is rotatably connected to a spherical rotating ball 4 via a fixing ring 5. A screw 7 is threaded to one side of the fixing ring 5. The end of the screw 7 near the rotating ball 4 is rotatably connected to an extrusion plate 8. The rotating ball 4 near the screw 7 has a frosted groove 6, and the frosted groove 6 and the extrusion plate 8 are connected. The contact surface has a frosted finish. The outer side of the rotating ball 4 is fixedly connected to the yarn roll rod 9. The yarn roll rod 9 is slidably connected to the inner periphery of the end away from the base 3 by the locking pin 10. There is a spring 12 between the locking pin 10 and the inside of the yarn roll rod 9. The outer side of the locking pin 10 is inclined, and the inner side has a pressure groove 11. The inner side of the yarn roll rod 9 is also slidably connected to the pull rod 13. The end of the pull rod 13 near the inside of the yarn roll rod 9 is fixed with multiple extrusion blocks 14. There is an extrusion inclined surface 15 at the contact point between the extrusion block 14 and the pressure groove 11. The outer side of the pull rod 13 is fitted with a spring 16. The frame 1 has multiple thread holes 30, 9 holes per group, totaling 10*10 groups, located on one side of the fixed plate 2.

[0074] Working principle: The rotating ball 4 can rotate between the base 3 and the fixing ring 5 to adjust the extension direction of the yarn coil rod 9. The screw 7 pushes the extrusion plate 8 to contact the abrasive groove 6. The abrasive surface restricts the rotation of the rotating ball 4, so that the yarn coil rod 9 always points to the yarn hole 27, ensuring that the yarn movement direction is in the same straight line as the yarn bobbin, avoiding the yarn pulling the yarn bobbin to rotate and the yarn bobbin interference causing yarn breakage. The spring 12 pushes the outer end of the locking pin 10 to protrude from the surface of the yarn coil rod 9, restricting the movement of the yarn bobbin sleeved on the outside of the yarn coil rod 9 and preventing it from slipping off. When installing the yarn bobbin, the inner wall of the yarn bobbin presses the locking pin 10 to tilt. The pull rod 13 moves the locking pin 10 inward for easy installation; pulling the pull rod 13 moves the squeezing block 14 and the squeezing inclined surface 15, forcing the locking pin 10 to move inward, allowing the yarn bobbin to be removed. After releasing the pull rod 13, the spring 16 pushes the squeezing block 14 to reset, and the locking pin 10 is also reset under the action of the spring 12. When warping different quantities of yarn, the number of yarn supply components is determined according to the quantity. The yarn passes through the thread hole 2 30 and the warning component in a specific order. For example, 1000 rolls of yarn require 10 sets of yarn supply components, and the yarn of a10 (1,1) needs to pass through multiple thread holes 2 30 before entering the warning component.

[0075] The structure of the early warning assembly consists of multiple sets of early warning assemblies that are engaged with the slots 18 on the lifting frame 26 via slide bars 20 and locked by pins 17 and sockets 21. Each set includes a fixed frame 19 with slide bars 20 and sockets 21 on both sides, 100 thread-passing holes 27 on the front and rear sides, a signal rod 25 installed in the middle, a fixed rod 22 fixed near the yarn supply assembly, 100 rotating rods 23 rotatably connected to the outside of the fixed rod 22, a torsion spring 24 between the rotating rods 23 and the fixed rod 22, and a thread-passing ring 28 fixed to the end of the rotating rod 23 away from the fixed rod 22. The square lifting frame 26 is rotatably connected to the middle of the fixed frame 19, and all the rotating rods 23 pass through the lifting frame 26.

[0076] Working principle: The yarn passes through the first thread guide hole 27, the thread guide ring 28 and the other thread guide hole 27. When winding, the yarn is taut and pulls up the thread guide ring 28, causing the rotating rod 23 to separate from the signal rod 25. After the yarn breaks, the rotating rod 23 contacts the signal rod 25 under the action of the torsion spring 24, breaking the initial state and realizing the warning. Rotating the lifting rod frame 26 can drive the rotating rod 23 and the thread guide ring 28 to be lifted, which facilitates yarn threading.

[0077] Finally, it should be noted that: obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation; for those skilled in the art, other variations or modifications can be made based on the above description; it is neither necessary nor possible to exhaustively list all implementation methods; and obvious variations or modifications derived therefrom are still within the protection scope of the present invention.
