Description

Technical Field

[0001] The present invention relates to the technical field of textile machinery, in particular to a high-speed stable yarn supply and yarn breakage early warning device for a warping machine. Background Art

[0002] Warping machines are critical equipment in the textile industry, used to wind a predetermined quantity of yarn onto a warp beam in parallel, to a specified length and width, in preparation for the subsequent weaving process. Their efficiency and yarn supply stability directly impact textile quality and production progress. Yarn supply is central to the warping machine's operation, ensuring continuous, uniform, and interference-free yarn delivery to the winding mechanism to meet the stringent yarn tension and path requirements of high-speed warping. Yarn break warnings monitor yarn status and issue timely signals when a break occurs, enabling operators to quickly address the situation and reduce downtime and defective products caused by breakage.

[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 winding device to rotate the bobbin to release the yarn. The yarn movement direction is often perpendicular to the bobbin, which can easily cause yarn breakage due to excessive tension. The other method adjusts the position to make the yarn movement direction parallel to the bobbin, but due to the large number of bobbins, it is difficult to maintain a uniform level, resulting in the yarn being affected by its own interference and affecting the release of the yarn, which is also prone to yarn breakage. At the same time, traditional early warning devices lack a precise sensing mechanism, making it difficult to detect yarn breakage in time. The threading process is cumbersome and difficult to adapt to the warping needs of different yarn quantities, seriously affecting warping efficiency.

[0004] Therefore, the present invention proposes a high-speed and stable yarn feeding and yarn breakage warning device for a warping machine, which uses a rotating ball with adjustable direction to keep the yarn movement direction and the yarn bobbin in the same straight line, and cooperates with the matrix-type wire holes and the hierarchical progressive threading method to reduce interference and yarn breakage; the yarn bobbin is conveniently installed and firmly fixed through the pin and pull rod structure; and the yarn breakage is timely warned through the induction cooperation of the rotating rod, the wire ring and the signal rod, ultimately achieving the effects of stable yarn feeding, convenient operation and timely detection of yarn breakage in the high-speed warping process, thereby improving the warping efficiency and quality. Summary of the Invention

[0005] Technical problems solved: Traditional yarn supply is prone to yarn breakage and early warning is not timely.

[0006] In view of the deficiencies in the prior art, the present invention provides a high-speed and stable yarn feeding and yarn breakage warning device for a warping machine, thereby solving the technical problems mentioned in the background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: The warping machine has a high-speed and stable yarn supply and yarn breakage warning device, including a yarn supply component and a warning component: The yarn supply assembly comprises: A rack with fixed trays arranged in a 10*10 array; The front side of the fixed plate is connected to the base through bolts, and the base is movably connected to the spherical rotating ball through a fixed ring; One side of the fixed ring is threadedly connected to the screw, and the end of the screw is rotated to connect to the extrusion disk, and a frosted groove is provided at the corresponding position of the rotating ball; The yarn winding rod is fixed on the outside of the rotating ball, and a latch with a spring 1 and a pull rod with a spring 2 are arranged inside the rod; The rack is provided with multiple sets of wire holes 2; The early warning component includes: A fixed frame, on which a slide bar, a socket and a wire hole are provided; A signal rod and a fixed rod are provided in the middle of the fixed frame, and the fixed rod is rotatably connected to a rotating rod with a torsion spring; A wire loop is provided at the end of the rotating rod, and the fixed frame is connected to the lifting frame; The rotating ball can adjust the fixed angle through the screw to keep the direction of the yarn winding rod consistent with the yarn movement trajectory; the early warning component realizes yarn break detection through the contact / separation of the rotating rod and the signal rod.

[0008] In one possible implementation, the rotating ball can rotate between the base and the fixed ring to adjust the extension direction of the yarn winding rod. The extrusion disk is pushed into contact with the frosted groove by the screw, and the frosted surface is used to limit the rotation of the rotating ball, so that the yarn winding rod always points to the wire hole one.

[0009] In one possible implementation, the spring pushes the outer end of the pin to protrude from the surface of the yarn winding rod to limit the movement of the yarn tube sleeved on the outside of the yarn winding rod to prevent it from slipping; the inclined surface design on the outside of the pin makes it easier to squeeze the pin inward when installing the yarn tube.

[0010] In one possible implementation, pulling the pull rod can drive the squeezing block and the squeezing slope to move, forcing the latch to move inward to remove the yarn bobbin; after releasing the pull rod, the second spring pushes the squeezing block to reset, and the latch is reset under the action of the first spring.

[0011] In a possible implementation, the number of yarn supply assemblies is determined according to the number of warping yarn rolls, and the yarn passes through the second thread hole and the warning assembly in a specific order; when 1000 rolls of yarn require 10 sets of yarn supply assemblies, a 10 The yarn passes through a plurality of thread holes and then enters the early warning component.

[0012] In one possible implementation, the yarn passes through the first thread hole, the thread ring and the first thread hole on the other side. When winding, the yarn is tightened and the thread ring is pulled up, so that the rotating rod and the signal rod are separated. After the thread breaks, the rotating rod contacts the signal rod under the action of the torsion spring, breaking the initial state to realize early warning.

[0013] In one possible implementation, the rebound force of the torsion spring can push the rotating rod to contact the signal rod, providing an initial trigger force for the yarn break warning. Rotating the lifting rod frame can drive the rotating rod and the threading ring to lift up, so that the threading ring is flush with the threading hole, facilitating the yarn threading operation.

[0014] In one possible implementation, the threading order of the yarn reels at different coordinates on each group of yarn supply components follows the same logic, that is, the yarns of the latter group of corresponding coordinates pass through the thread holes 2 of the former group of corresponding coordinates in turn and then enter the early warning component.

[0015] Beneficial effects compared with existing technologies: 1. In this solution, the precise alignment of the yarn movement direction and the yarn bobbin is achieved through the cooperation of the rotating ball with adjustable direction and the yarn winding rod. The rotating ball can flexibly rotate between the base and the fixed ring, and the extension direction of the yarn winding rod is adjusted so that it always points to the thread hole 1. The screw is used to push the extrusion disk to contact the frosted surface of the frosting groove at a fixed angle, avoiding the problem of the yarn pulling the yarn bobbin to rotate or being interfered with by the yarn bobbin due to direction deviation in traditional yarn supply, reducing the risk of yarn breakage, and ensuring the stability of high-speed yarn supply.

[0016] 2. In this solution, timely warning of yarn breakage is achieved through the inductive coordination of the rotating rod, thread ring and signal rod in the early warning component. When the yarn is taut, the thread ring drives the rotating rod and the signal rod to separate. After the yarn breaks, the torsion spring pushes the rotating rod to contact the signal rod, breaking the initial state and triggering the early warning. At the same time, the lifting rod frame facilitates yarn threading. Multiple sets of early warning components can be adapted to different yarn quantities, ensuring that yarn breaks are quickly detected during the warping process and reducing production delays caused by yarn breaks.

[0017] 3. In this scheme, the yarn threading path is planned according to the order of yarn supply components and coordinate numbers, so that the yarn can be combed in an orderly manner when multiple yarn supply components work together. For example, when 1000 rolls of yarn correspond to 10 sets of yarn supply components, a 10 The yarn of (1,1) passes through a9 (1,1)9 to a1 (1,1)9 in turn and then enters the warning component. This hierarchical threading logic avoids the entanglement and interference of multiple groups of yarns during the yarn feeding process, ensuring the neatness and order of a large number of yarns when feeding at the same time; the number of yarn feeding components and the threading sequence are flexibly adjusted according to the number of warping yarns, realizing the adaptation to the warping needs of different scales. For example, when 500 rolls of yarn use 5 groups of yarn feeding components, the yarn of a5 (6,3) is arranged according to a4 (6,3)9→a3 (6,3)9→a2 (6,3)9→a 1（6,3) 9 → Sequential threading of the warning assembly meets varying production requirements without requiring additional adjustments to the equipment structure, enhancing the device's versatility and practicality. Combined with the matrix arrangement of the second threading hole and the yarn supply assembly, precise yarn guidance from the supply to the warning assembly is achieved. The second threading hole next to each fixed disk forms a dedicated channel for the corresponding yarn reel. A rotating ball adjusts the direction of the yarn reel rod, ensuring stable yarn movement along the preset path. This reduces friction and pulling caused by path deviation, further minimizing the probability of yarn breakage and ensuring stable high-speed yarn supply. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The 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 forms, so the present invention is not limited to the embodiments described below. In addition, in order to describe the present invention more clearly, parts that are not connected with the invention will be omitted from the accompanying drawings.

[0021] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows: The yarn is then fed back into the yarn feeder, and the yarn feeder is ... Therefore, this embodiment introduces the specific structure of the high-speed stable yarn supply and yarn breakage warning device of the warping machine, please refer to Figures 1 to 17 As shown, the yarn feeding and yarn breakage warning device includes a yarn feeding assembly, which is provided with 10 groups of yarn feeding assemblies, each group including a rack 1, a group of 10*10 fixed disks 2 are provided on the rack 1, the front side of each fixed disk 2 is mounted with a base 3 by bolts, the front side of the base 3 is rotatably connected to a spherical rotating ball 4 through a fixing ring 5, one side of the fixing ring 5 is threadedly connected to a screw 7, and the end of the screw 7 close to the rotating ball 4 is rotatably connected to an extrusion disk 8, and a frosted groove 6 is provided on the side of the rotating ball 4 close to the screw 7, and the frosted groove 6 and the side of the extrusion disk 8 close to the frosted groove 6 are both set as frosted surfaces; The outer side of the rotating ball 4 is fixedly connected to a yarn winding rod 9, which is pushed by the screw 7 to squeeze the extrusion plate 8 into contact with the frosting groove 6, and then the rotation of the rotating ball 4 is limited by the frosted surface of the two. When the extrusion plate 8 is not in contact with the frosting groove 6, the extension direction of the yarn winding rod 9 is adjusted by rotating the rotating ball 4 between the base 3 and the fixed ring 5. By adjusting the extension direction of the yarn winding rod 9, the yarn winding rod 9 can always point to the threading hole 27 where the thread needs to be threaded, so that the moving direction of the yarn and the yarn drum are in the same straight line. In this way, it is possible to avoid the need to pull the yarn drum to rotate in order to realize the yarn unwinding. On the other hand, the yarn unwinding can also avoid the situation where the yarn winding rod 9 cannot be at the same level as the threading hole 27, and the yarn is disturbed by the yarn drum itself when moving, which affects the yarn unwinding and then causes yarn breakage. The inner part of the end of the yarn winding rod 9 away from the base 3 is slidably connected with a latch 10 on all sides. A spring 12 is provided between the latch 10 and the inner part of the yarn winding rod 9. The rebound force of the spring 12 pushes the outer end of the latch 10 to protrude from the surface of the yarn winding rod 9. Then, when the yarn bobbin is sleeved on the outer side of the yarn winding rod 9, the latch 10 can limit the movement of the yarn bobbin. Then, when the yarn winding rod 9 is adjusted in direction, if the angle is tilted downward, the yarn bobbin can be prevented from sliding off the outer side of the yarn winding rod 9. The outer side of the bayonet 10 is designed with an inclined surface. With this design, when the yarn bobbin is installed on the outer side of the yarn winding rod 9, the inner wall of the yarn bobbin can squeeze the inclined surface of the bayonet 10, and then squeeze the bayonet 10 to move inward, and then the yarn bobbin can be directly installed on the outer side of the yarn winding rod 9. The inner sides of the plurality of bayonet pins 10 are all provided with pressure grooves 11, and the inner side of the end of the yarn winding rod 9 away from the base 3 is also slidably connected to a pull rod 13, and the end of the pull rod 13 close to the inner side of the yarn winding rod 9 is also fixedly connected to a plurality of extrusion blocks 14, and the junction of the plurality of extrusion blocks 14 and the pressure groove 11 is provided with an extrusion inclined surface 15. By pulling the pull rod 13, the extrusion block 14 is driven and the extrusion inclined surface 15 is driven to move toward the inner side of the pressure groove 11. Due to the special design of the inclined surface of the extrusion inclined surface 15, when the extrusion block 14 gradually moves to the inner side of the pressure groove 11, it also moves and forces the bayonet pin 10 to move toward the inner side of the yarn winding rod 9. When the bayonet pin 10 is completely moved into the inner side of the yarn winding rod 9, the bayonet pin 10 no longer restricts the movement of the yarn bobbin, and the yarn bobbin can be moved out from the outer side of the yarn winding rod 9; In addition, a second spring 16 is sleeved on the outer side of the pull rod 13. The second spring 16 is arranged between the extrusion block 14 and the inner wall of the yarn winding rod 9. When the pull rod 13 drives the extrusion block 14 to move into the inner part of the pressure groove 11, the extrusion block 14 and the inner wall of the yarn winding rod 9 squeeze the second spring 16. When the yarn bobbin is moved out, 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 of the pressure groove 11, and then contact the restriction of the bayonet 10. At this time, the bayonet 10 is also reset under the push of the first spring 12. The rack 1 is provided with a plurality of wire holes 30, which are grouped into 9 groups, totaling 10*10 groups, and are respectively provided on one side of the fixed plate 2, such as Figure 1 and Figure 14 When there are multiple yarn supply components, they are arranged one after another, and the multiple yarn supply components are recorded as a1, a2, ..., a 10 , since the yarn winding rods 9 are arranged in a 10*10 matrix on a single rack 1, as Figure 2 As shown, each fixed disk 2 can be provided with a single number such as a1 (1, 1), a1 (10, 9), a5 (6, 7), etc.; in addition, as Figure 3 As shown, the nine second wire holes 30 next to each fixing plate 2 are set as a group therewith, and each second wire hole 30 is also individually numbered, such as a1 (1, 1) 1, a1 (1, 1) 2, a1 (2, 2) 1; like Figure 1 and 14 , assuming that the number of yarns to be warped this time is 1000 rolls in total, 10 sets of yarn supply components need to be set up, and these 10 groups are arranged one by one in a certain interval in order (the one close to the warning component is first, and the one far away from the warning component is last). When threading, the yarn of a1 (1,1) is passed directly through the warning component, and the yarn of a2 (1,1) needs to pass through a1 (1,1)1 first and then through the warning component. Therefore, the yarn crossing order of a3 (1,1) is a2 (1,1)2→a1 (1,1)2→warning component, and the yarn crossing order 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 crossing order 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; Similarly, the threading order of the yarn reels with coordinates (2, 2) on each group of yarn supply components is: the yarn of a1 (2, 2) directly passes through the early warning component, the yarn of a2 (2, 2) passes through the order of a1 (2, 2) 1 → early warning component, the yarn of a3 (2, 2) passes through the order of a2 (2, 2) 2 → a1 (2, 2) 2 → early warning component, the yarn of a4 (2, 2) passes through the order of a3 (2, 2) 3 → a2 (2, 2) 3 → a1 (2, 2) 3 → early warning component, and so on. 10 The yarn crossing order 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; The threading order of the yarn reels with coordinates (4, 3) on each group of yarn supply components is as follows: the yarn of a1 (4, 3) directly passes through the early warning component, the yarn of a2 (4, 3) passes through the order of a1 (4, 3) 1 → early warning component, the yarn of a3 (4, 3) passes through the order of a2 (4, 3) 2 → a1 (4, 3) 2 → early warning component, the yarn of a4 (4, 3) passes through the order of a3 (4, 3) 3 → a2 (4, 3) 3 → a1 (4, 3) 3 → early warning component, and so on. 10 The yarn crossing order 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; In addition, assuming that only 500 rolls of yarn need to be warped, 5 groups of yarn supply components need to be set up, and these 5 groups are arranged one by one in a certain order at a certain distance. Taking the threading order of the yarn rolls with coordinates (6, 3) on each group of yarn supply components as an example, the yarn a1 (6, 3) directly passes through the early warning component, the yarn a2 (6, 3) passes through the order of a1 (6, 3) 1 → early warning component, the yarn a3 (6, 3) passes through the order of a2 (6, 3) 2 → a1 (6, 3) 2 → early warning component, the yarn a4 (6, 3) passes through the order of a3 (6, 3) 3 → a2 (6, 3) 3 → a1 (6, 3) 3 → early warning component, and the yarn a5 (6, 3) passes through the order of a4 (6, 3) 9 → a3 (6, 3) 9 → a2 (6, 3) 9 → a1 (6, 3) 9 → early warning component; Based on the above, when warping of different numbers of yarn reels is required, the number of yarn supply assemblies required and the threading of the yarn between the yarn supply assemblies can be determined; like Figures 8 to 13 As shown, it includes multiple groups of warning components. Each group of warning components is installed on the lifting rod frame 26 by engaging the slide bar 20 on the warning component with the slot 18 on the lifting rod 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. Each set of warning components includes a fixed frame 19, and both sides of the fixed frame 19 are provided with slide bars 20 and jacks 21. The front and rear sides of the fixed frame 19 are provided with 100 wire holes 27, a signal rod 25 is installed in the middle, and a fixed rod 22 is fixedly connected to the side of the middle close to the yarn supply assembly. The outer side of the fixed rod 22 is rotatably connected to 100 rotating rods 23, and a torsion spring 24 is provided between the plurality of rotating rods 23 and the fixed rod 22. The rebound force of the torsion spring 24 pushes the rotating rod 23 to contact the signal rod 25, and the ends of the plurality of rotating rods 23 away from the fixed rod 22 are fixedly connected to the wire ring 28; Ten groups of early warning components can be installed on a lifting rod frame 26. Of course, it can be designed according to actual conditions. After the yarn roll is initially combed by the yarn supply component, Figure 12 As shown, each yarn is passed through the thread hole 27 on one side of the yarn supply assembly, then through the thread ring 28, and finally through the thread hole 27 on the other side. A contact sensor is provided between the rotating rod 23 and the signal rod 25. When the yarn passes through the thread ring 28 and is winding the yarn, the yarn tension will lift the thread ring 28, and then the rotating rod 23 and the signal rod 25 are separated. The thread ring 28 that has not been threaded continues to be in contact with the signal rod 25 under the action of the rebound force of the torsion spring 24. The state before winding after threading is completed is set as the initial state. When the thread breaks, the rotating rod 23 lifted by the yarn is rebounded by the torsion spring 24 again and contacts the signal rod 25. In this way, the initial state is broken, which then serves as an early warning. like Figure 1 and Figure 15 The early warning component is matched with the yarn supply component. According to the number of yarn rolls to be warped, the appropriate amount of yarn supply component and early warning component are selected. The specific use of the two is as follows: Figure 15 As shown ( Figure 15 The diagram on the left shows a set of yarn supply components with a set of early warning components, which can be used to warp up to 100 yarn rolls. The diagram on the right shows two sets of yarn supply components with two sets of early warning components, which can be used to warp up to 200 yarn rolls. Subsequent yarn supply components are added in sequence to the right, and early warning components are added in sequence upwards. Assuming that 100 yarn rolls need to be warped, only one set of yarn supply components and one set of early warning components are required. The 100 yarn rolls are passed through the yarn supply components in the order of 1-10 on the x-axis and then 1-10 on the y-axis from the left to the right of the early warning components. One set of yarn supply components corresponds to one set of early warning components. Assuming that there are more than 100 yarn rolls, such as 200 yarn rolls, the yarn should be arranged first according to the threading order of the yarn supply component. At this time, the threading order of the early warning component should be carried out in the order of first bottom and then top, first left and then right. Starting from the yarn in the lower left corner of the yarn supply component, first pass through the thread hole 27 on the left side of the lower early warning component, and thread the yarn to the right in sequence. When all the early warning components on the lower side are threaded, upgrade to the early warning component on the upper side until the yarn threading is completed; The same goes for 350 rolls, 540 rolls, and so on. First, thread the yarn in the order of the yarn supply component, and then pass it through the warning component in the order of bottom first, top second, left first, and right second to complete the yarn combing work. The middle part of the fixed frame 19 is rotatably connected to a lifting rod frame 26 of square design. A plurality of rotating rods 23 pass through the lifting rod frame 26. When one side of the lifting rod frame 26 is rotated, the other side thereof is tilted, thereby driving the rotating rod 23 to be lifted. When the rotating rod 23 is lifted, the thread ring 28 can be lifted. By lifting the thread ring 28, it is flush with the thread hole 27, thereby facilitating the threading work. like Figure 16 and Figure 17 The yarn on the early warning component is connected to the combing roller 31 in the order from bottom to bottom and from the middle to both sides, and the winding order of the yarn on the combing roller 31 is from the middle to both sides. The regular winding can avoid interference between the wire bundles. In addition, winding step by step in sequence can avoid the wire bundles being too loose, which affects the warping effect. In summary, the yarn supply component structure is composed of: a total of 10 groups (multiple groups can be set, depending on the display, the size of the rack 1 and the number of fixed disks 2 on the rack 1, including the number of wire holes 30, can be changed according to actual conditions), each group includes a rack 1, and a 10*10 fixed disk 2 is provided on the rack 1. The front side of each fixed disk 2 is mounted on a base 3 by a bolt, and the front side of the base 3 is rotatably connected to a spherical rotating ball 4 through a fixing ring 5. One side of the fixing ring 5 is threadedly connected to a screw rod 7, and the end of the screw 7 close to the rotating ball 4 is rotatably connected to an extrusion disk 8. The rotating ball 4 has a frosting groove 6 on the side close to the screw 7, and the frosting groove 6 and the extrusion disk 8 are connected. The contact surface is frosted, and the outer side of the rotating ball 4 is fixedly connected to the yarn winding rod 9. The yarn winding rod 9 is away from the base 3 and is slidably connected to the bayonet 10 around the inner side. There is a spring 12 between the bayonet 10 and the inner side of the yarn winding rod 9. The outer side of the bayonet 10 is an inclined surface, and a pressure groove 11 is opened on the inner side. The yarn winding rod 9 is also slidably connected to the pull rod 13 at the inner side of the end away from the base 3. A plurality of extrusion blocks 14 are fixed on the inner end of the pull rod 13 close to the yarn winding rod 9. There is an extrusion inclined surface 15 at the contact point between the extrusion block 14 and the pressure groove 11, and a spring 16 is sleeved on the outer side of the pull rod 13; there are multiple wire holes 30 on the shelf 1, 9 of which are grouped into 10*10 groups, and are arranged on one side of the fixed disk 2; Working principle: the rotating ball 4 can rotate between the base 3 and the fixed ring 5 to adjust the extension direction of the yarn winding rod 9, and the extrusion disk 8 is pushed to contact the frosted groove 6 through the screw 7. The frosted surface is used to limit the rotation of the rotating ball 4, so that the yarn winding rod 9 always points to the thread 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 interference of the yarn bobbin to cause yarn breakage; the spring 12 pushes the outer end of the latch 10 to protrude from the surface of the yarn winding rod 9, limiting the movement of the yarn bobbin on the outside of the yarn winding rod 9 and preventing it from slipping; when installing the yarn bobbin, the inner wall of the yarn bobbin squeezes the latch 10 to tilt The surface causes the latch 10 to move inward for easy installation; pulling the pull rod 13 drives the extrusion block 14 and the extrusion slope 15 to move, forcing the latch 10 to move inward, and the yarn bobbin can be taken out. After loosening the pull rod 13, the spring 2 16 pushes the extrusion block 14 to reset, and the latch 10 is also reset under the action of the spring 12; when warping different numbers of yarn rolls, the number of yarn supply components is determined according to the number, and 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 a10 (1,1) needs to pass through multiple thread holes 2 30 before entering the warning component; The structure of the warning assembly consists of: multiple groups of warning assemblies are installed by engaging with the card slots 18 on the lifting rod frame 26 through the slide bar 20, and are locked by the pin 17 and the socket 21; each group includes a fixed frame 19, which has slide bars 20 and sockets 21 on both sides, 100 wire holes 27 on the front and back sides, a signal rod 25 installed in the middle, a fixed rod 22 is fixed on the side close to the yarn supply assembly, and the outer side of the fixed rod 22 is rotatably connected to 100 rotating rods 23, a torsion spring 24 is provided between the rotating rod 23 and the fixed rod 22, and a wire ring 28 is fixed on the end of the rotating rod 23 away from the fixed rod 22; the middle part of the fixed frame 19 is rotatably connected to the square lifting rod frame 26, and the rotating rods 23 all pass through the lifting rod frame 26; Working principle: the yarn passes through the thread hole 27, the thread ring 28 and the thread hole 27 on the other side. When winding, the yarn is tightened and the thread ring 28 is lifted, so that the rotating rod 23 is separated from the signal rod 25; after the thread breaks, the rotating rod 23 contacts the signal rod 25 under the action of the torsion spring 24, breaking the initial state to realize early warning; rotating the lifting rod frame 26 can drive the rotating rod 23 and the thread ring 28 to lift up, making it easier to thread the yarn.
