Description

Technical Field

[0001] This application relates to the field of weaving technology, and in particular to a bipolar tension-regulating flexible transmission device suitable for weaving technology. Background Technology

[0002] Currently, in weaving processes, the warping frame, as the core equipment for arranging yarn packages according to a certain pattern and applying appropriate tension, has a crucial impact on the quality and production efficiency of woven products. With the continuous progress and expansion of the textile industry, the types of fiber materials are constantly becoming more diverse. From the initially widely used common fibers such as cotton and polyester, to the later emerging new fibers such as glass fiber and basalt fiber, they have demonstrated unique advantages and application value in various fields. The extensive application of new fibers necessitates continuous innovation and improvement in warping technology to adapt to the special warping needs of different fiber materials, thereby improving the quality and production efficiency of woven products.

[0003] In traditional weaving processes, various conventional methods are employed to address tension adjustment during warping. For warping ordinary fibers, traditional warping frames primarily rely on tension rollers and pressure plates for tension adjustment. The tension rollers apply tension to the fibers through contact and rolling, while the pressure plates further regulate the tension by adjusting the pressure applied to the fibers. For warping special fibers such as glass fibers and basalt fibers, two approaches are used: first, adding a tension adjustment frame with multiple tension plates, allowing each glass fiber bundle to pass through a separate tension plate for tension adjustment; second, installing tension rollers followed by ceramic perforations. Additionally, other auxiliary methods, such as adding guiding devices, are employed to ensure smooth fiber transport during the warping process.

[0004] Regarding the aforementioned technologies, tension rollers are commonly made of stainless steel or galvanized steel. Friction between the fibers and the surface of these materials can easily lead to increased fuzz, affecting the quality of the finished product. While ceramic holes can reduce friction to some extent, they cannot effectively solve the static electricity problem. Furthermore, static electricity attracts dust and lint from the air, further exacerbating the fuzz problem and potentially causing fibers to entangle, affecting the smoothness of unwinding and further reducing product quality. Summary of the Invention

[0005] To improve product quality, this application provides a bipolar tension-adjustable flexible transmission device suitable for weaving processes.

[0006] This application provides a bipolar tension-adjustable flexible transmission device suitable for weaving processes, employing the following technical solution: A bipolar tension-regulating flexible transmission device suitable for weaving processes includes a weaving device and several warping frames arranged perpendicular to the yarn transmission direction. Each warping frame includes a frame body, several support plates, and several antistatic guide components. The antistatic guide components are located above the corresponding support plates. The support plates and antistatic guide components are arranged sequentially along the height direction of the frame body. Each antistatic guide component includes two pressure rollers arranged along the yarn transmission direction. The pressure rollers are rotatably connected to the support plates perpendicular to the yarn transmission direction. A roller assembly is provided at one end of the weaving device near the warping frame. The part of the roller assembly that contacts the yarn and the surface of the pressure roller are both made of antistatic material.

[0007] By adopting the above technical solution, this bipolar tension-regulating flexible transmission device, with its several warping frames arranged perpendicular to the yarn transmission direction, and each warping frame including a support plate and an anti-static guide assembly arranged sequentially along the height of the frame, is suitable for unwinding yarns of various winding forms and is compatible with the warping needs of both internally wound and externally wound packaged yarns. The two pressure rollers in the anti-static guide assembly are arranged along the yarn transmission direction and rotatably connected to the support plate. Furthermore, the yarn-contacting parts and pressure roller surfaces in the roller assembly near the warping frame end of the weaving device are all made of anti-static material. This improves the accuracy of tension regulation, meets the special requirements of glass fiber and basalt fiber, reduces static electricity, fly waste, and fuzz, minimizes the adverse effects of friction between glass fiber and basalt fiber and surfaces such as stainless steel or galvanized rollers, protects brittle fibers from breakage during warping, and improves the quality of the finished product.

[0008] Optionally, the antistatic guide assembly further includes a guide plate and a guide sleeve. The guide plate is fixedly connected to one end of the frame near the weaving device. The guide plate has several guide holes for inserting the guide sleeve. The pressure roller is located on the side of the guide plate away from the weaving device.

[0009] By adopting the above technical solution, the yarn can be guided more accurately during transmission, avoiding yarn deviation and ensuring that the yarn accurately enters the weaving device, thus improving the stability of yarn transmission. In addition, in conjunction with the pressure roller, the accuracy of tension adjustment is further improved, better meeting the special warping requirements of glass fiber and basalt fiber. At the same time, due to the setting of the guide sleeve, the friction between the yarn and the guide component can be reduced to a certain extent, reducing the generation of fuzz and static electricity, which is conducive to improving the quality of finished products.

[0010] Optionally, the antistatic material is copper, antistatic ceramic, or antistatic fiberglass.

[0011] By adopting the above technical solution, the antistatic materials for the roller and pressure roller surfaces are selected as copper, antistatic ceramics, or antistatic fiberglass. Compared with commonly used materials such as stainless steel pipes, copper, antistatic ceramics, and antistatic fiberglass have moderate hardness and good antistatic properties. During yarn transmission, it can effectively reduce static electricity generated by friction between the yarn and the roller and pressure roller surfaces, thereby reducing fly yarn caused by static adsorption. At the same time, it avoids yarn fuzz caused by static electricity, meeting the special requirements of glass fiber and basalt fiber in reducing static electricity, fly yarn, and fuzz during the warping process, and improving the finished yarn quality.

[0012] Optionally, the roller assembly has a frame on the side near the warping frame, and a number of elastic spacers are fixed inside the frame. The elastic spacers are used to limit the position of the yarn and for cleaning.

[0013] By adopting the above technical solution, the elastic spacer can limit the yarn, keeping the yarn in a stable position during transmission and preventing the yarn from shifting or shaking. At the same time, the elastic spacer can also clean the yarn, removing impurities and dust attached to the yarn surface, improving the cleanliness of the yarn, and thus improving the quality of the weaving process and the quality of the final product.

[0014] Optionally, the roller assembly has several selvage tension adjustment components arranged perpendicular to the yarn transport direction on the side near the warping frame. Each selvage tension adjustment component includes a base plate, a guide, and two sets of limiting components arranged along the yarn transport direction. The guide is located between the two sets of limiting components, and the limiting components are installed on the upper surface of the base plate. The base plate has an arc-shaped groove coaxial with one of the limiting components. The lower end of the guide passes through the arc-shaped groove and is rotatably connected to the base plate along the axis of the arc-shaped groove.

[0015] By adopting the above technical solution, the limiting component in the selvage tension adjustment assembly can limit the selvage yarn, and the guide component, located between the two sets of limiting components, can guide the transmission direction of the yarn. Simultaneously, the arc-shaped groove on the base plate, coaxial with one of the limiting components, allows the lower end of the guide component to rotate and connect with the base plate along the axis of the arc-shaped groove. This enables flexible adjustment of the yarn tension and direction, achieving fine adjustment of the selvage tension and improving the accuracy of tension adjustment.

[0016] Optionally, the limiting component includes a guide cylinder, a lower disc, an upper disc, an elastic element, and a clamping element. The lower disc, the upper disc, and the elastic element are sequentially sleeved on the outside of the guide cylinder from bottom to top. The clamping element is located above the guide cylinder. The elastic element is sandwiched between the upper disc and the clamping element. The guide cylinder is fixedly connected to the upper end face of the base plate.

[0017] By adopting the above technical solution, the yarn can be effectively limited. The elastic element can expand and contract according to the yarn tension changes, thereby adaptively adjusting the pressure on the yarn, improving the accuracy of yarn tension adjustment, and meeting the requirements of precise tension control for special fibers such as glass fiber and basalt fiber during warping. At the same time, this structural design can reduce yarn swaying and deviation during transmission, reduce friction between the yarn and other components, thereby reducing static electricity, fly hair, and fuzz, and improving the quality of the finished product.

[0018] Optionally, the limiting assembly further includes a first bolt and a second bolt. The threaded end of the first bolt passes through the clamping member, guide cylinder, and base plate of one of the limiting assemblies in sequence from top to bottom. The first bolt is coaxially fixedly connected to a first fastener. A second fastener is provided below the base plate and threadedly connected to the first bolt. The threaded end of the second bolt passes through the base plate, the guide cylinder of the other limiting assembly, and the clamping member in sequence from bottom to top. The second bolt is threadedly connected to a third fastener. The first fastener and the third fastener are respectively located between the corresponding clamping member and the guide cylinder. The second bolt is threadedly connected to the corresponding clamping member.

[0019] By adopting the above technical solution, the first and second bolts ensure that the limiting assembly can be securely installed on the base plate. The first and third fasteners work together to fix the corresponding guide cylinder, and the second and third fasteners work together to fix the corresponding guide cylinder. The bolted connection between the first and second fasteners and the threaded connection between the second bolt and the corresponding clamping member respectively compress the corresponding elastic element and the upper disc, thereby adjusting the tension of the limiting assembly to meet the tension requirements of glass fiber and basalt fiber during the warping process.

[0020] Optionally, a rotating plate is sandwiched between the second fastener and the lower end face of the base plate. The rotating plate is rotatably connected to the first bolt along the axis of the first bolt, and the lower end of the guide is fixedly connected to the upper end face of the rotating plate.

[0021] By adopting the above technical solution, the guide component can rotate around the axis of the first bolt. During yarn transmission, the position of the guide component can be adjusted by flexibly rotating the rotating plate according to the actual situation, thereby adjusting the yarn tension. This effectively improves the accuracy of yarn tension and position adjustment, ensures the stability of the yarn during transmission, and avoids yarn deviation, knotting, and other issues, thus guaranteeing the smooth progress of the weaving process and the quality of the finished product.

[0022] Optionally, the frame is fixedly provided with a number of support frames for supporting the bearing plate. The lower end face of the bearing plate abuts against the upper end face of the support frame. Above the bearing plate, there are a number of sliding shafts arranged along the yarn transmission direction and fixedly connected to the bearing plate. A number of pulleys are sleeved on the outside of the sliding shafts. The pulleys are slidably connected to the sliding shafts along their own axial direction and rotatably connected to the sliding shafts along their own axis.

[0023] By adopting the above technical solution, the support frame installed on the frame can support the bearing plate, ensuring its stability and thus the overall structural integrity of the device. A sliding shaft is installed above the bearing plate, arranged along the yarn transmission direction and fixedly connected to it. Pulleys fitted on the outer side of the sliding shaft can be slidably and rotatably connected to the sliding shaft along their own axes. This design allows the pulleys to rotate flexibly with the movement of the yarn during transmission. The pulleys can slide according to the position of the guide holes, reducing friction between the yarn and the bearing plate, lowering the probability of yarn damage, ensuring smooth yarn transmission, and also helping to improve the efficiency of yarn transmission.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. This bipolar tension-regulating flexible transmission device, equipped with several warping frames arranged perpendicular to the yarn transmission direction, and each warping frame including a support plate and an anti-static guide assembly arranged sequentially along the height of the frame, is suitable for unwinding yarns of various winding forms and is compatible with the warping needs of both internally wound and externally wound packaged yarns. The two pressure rollers in the anti-static guide assembly are arranged along the yarn transmission direction and rotatably connected to the support plate. The parts of the roller assembly near the warping frame of the weaving device that come into contact with the yarn and the surface of the pressure rollers are all made of anti-static material. This improves the accuracy of tension regulation, meets the special requirements of glass fiber and basalt fiber, reduces the generation of static electricity, fly hair, and fuzz, reduces the adverse effects of friction between glass fiber and basalt fiber and surfaces such as stainless steel or galvanized rollers, protects brittle fibers from breakage during the warping process, and improves the quality of the finished product. 2. It enables more precise guidance of the yarn during transmission, preventing yarn deviation and ensuring that the yarn accurately enters the weaving device, thus improving the stability of yarn transmission. In conjunction with the pressure roller, it further enhances the precision of tension adjustment, better meeting the special warping requirements of glass fiber and basalt fiber. At the same time, due to the setting of the guide sleeve, it can reduce the friction between the yarn and the guide components to a certain extent, reducing the generation of fuzz and static electricity, which is conducive to improving the quality of finished products. 3. The antistatic materials used for the rollers and pressure rollers are copper, antistatic ceramics, or antistatic fiberglass. Compared to commonly used materials such as stainless steel pipes, copper, antistatic ceramics, and antistatic fiberglass have moderate hardness and good antistatic properties. During yarn transport, they effectively reduce static electricity generated by friction between the yarn and the rollers / pressure rollers, thereby reducing fly yarn caused by static adsorption. They also prevent yarn fuzzing caused by static electricity, meeting the specific requirements of glass fiber and basalt fiber in reducing static electricity, fly yarn, and fuzz during warping, thus improving the quality of the finished yarn.

Detailed Implementation

[0035] The present application will be further described in detail below with reference to all the accompanying drawings.

[0036] This application discloses a bipolar tension-adjustable flexible transmission device suitable for weaving processes.

[0037] Reference Figure 1A bipolar tension-regulating flexible transmission device suitable for weaving processes includes a weaving device 1 and several warping frames 2 arranged perpendicular to the yarn transmission direction. The weaving device 1 is used to weave the weft threads of several warp threads output from the warping frames 2. The warping frames 2 are mainly used to wind the yarn parallel and evenly from the yarn bobbins onto the warp beams of the weaving device 1, preparing for subsequent weaving processes. The number of yarn bobbins is determined according to the number of warp threads required for the width of the fabric to be woven in actual production needs, thereby determining the number of warping frames 2. The warping frames 2 and the weaving device 1 cooperate to achieve stable yarn transmission from the warping frames 2 to the weaving device 1, achieving the effect of meeting the warping requirements of special fibers such as glass fiber and basalt fiber, and improving the quality of woven products.

[0038] Reference Figure 2 The warping frame 2 includes a frame body 21, several support plates 22, and several anti-static guide components 23. The frame body 21 is the main supporting structure of the warping frame 2, typically made of metal, and possesses high strength and stability. The support plates 22 are used to hold components such as yarn bobbins; by fixing U-shaped plates to the upper surface of the support plates 22, they can be transported using a forklift. The anti-static guide components 23 are used to guide the yarn and perform initial tension adjustment. The support plates 22 and the anti-static guide components 23 are arranged sequentially along the height of the frame body 21.

[0039] Reference Figure 2 The frame 21 is fixed with several support frames 211 along the vertical direction. The lower end face of the bearing plate 22 abuts against the upper end face of the support frame 211. The support frame 211 is fixedly connected to the frame 21 by welding or bolts, etc., to provide stable support for the bearing plate 22.

[0040] Reference Figure 2 and Figure 3 The antistatic guide assembly 23 is located above the corresponding support plate 22. The antistatic guide assembly 23 includes a guide plate 232 and a guide sleeve 233. The guide plate 232 is fixedly connected to the end of the frame 21 near the weaving device 1. The guide plate 232 has several guide holes for inserting the guide sleeve 233. The pressure roller 231 is located on the side of the guide plate 232 away from the weaving device 1. The guide plate 232 is generally a metal plate, and its function is to guide the yarn so that it can accurately enter the guide sleeve 233. The guide sleeve 233 is usually made of antistatic ceramic material, which has a low coefficient of friction, reducing friction between the yarn and the guide sleeve 233. After the guide sleeve 233 is inserted into the guide hole, it can be fixed by glue or by interference fit.

[0041] Reference Figure 2 and Figure 3Mounting brackets are fixedly installed on both sides of the upper surface of the support plate 22 along the yarn transmission direction. Several sliding shafts 24, arranged along the yarn transmission direction and fixedly connected to the support plate 22, are located above it. Both ends of the sliding shafts 24 are fixedly connected to the mounting brackets. Several pulleys 241 are sleeved on the outer side of the sliding shafts 24, and the pulleys 241 are slidably connected to the sliding shafts 24 along their own axes. The position of the guide hole for threading is determined according to the number of yarn bobbins placed on each layer of the support plate 22, and then the position of the pulleys 241 is adjusted so that each pulley 241 is aligned with one of the guide holes. The pulleys 241 are rotatably connected to the sliding shafts 24 along their own axes, and their function is to guide the transmission of the yarn.

[0042] Reference Figure 2 and Figure 3 The antistatic guide assembly 23 also includes two pressure rollers 231 arranged along the yarn transport direction. The pressure roller 231 furthest from the weaving device 1 is positioned above the pressure roller 231 closest to the weaving device 1. The pressure rollers 231 are rotatably connected to the support plate 22 perpendicular to the yarn transport direction. The pressure rollers 231 can be made of antistatic materials such as copper, antistatic ceramic, or antistatic fiberglass. These materials not only effectively reduce static electricity generation but also lower the coefficient of friction with the yarn, reducing fuzz formation. The surface of the pressure roller 231 is a smooth cylindrical surface. Both ends of the pressure roller 231 are rotatably connected to the mounting bracket on the support plate 22 via bearings to ensure flexible rotation of the pressure roller 231.

[0043] Reference Figure 4 The weaving device 1 has a roller assembly 3 located at one end near the warping frame 2. Through the cooperation of the warping frame 2 and the roller assembly 3, bipolar tension adjustment during yarn transport is achieved, improving the accuracy of tension adjustment and meeting the warping requirements of special fibers such as glass fiber and basalt fiber. The rollers and pressure rollers 231 in the roller assembly 3 are both made of anti-static material, such as copper, anti-static ceramic, or anti-static fiberglass. This effectively prevents the generation of static electricity during yarn transport, reducing fuzz and fly waste, and improving the quality of the finished product. The rollers in the roller assembly 3 can be a single roller or a group of multiple rollers, selected according to the actual tension adjustment requirements.

[0044] The rollers in roller assembly 3 and the pressure rollers 231 in antistatic guide assembly 23 can also be replaced by stainless steel rollers with antistatic coatings on the surface, instead of pressure rollers made of copper, antistatic ceramic, or antistatic fiberglass. These stainless steel rollers with antistatic coatings on the surface ensure a certain level of strength while also providing antistatic protection.

[0045] Reference Figure 4The roller assembly 3 includes a frame 31, two guide rollers 32, a first tension roller 33, a second tension roller 34, and a false warp beam 35. The two guide rollers 32 and the false warp beam 35 are arranged sequentially along the yarn transport direction, and both the guide rollers 32 and the false warp beam 35 are located below the tension rollers. The two ends of the second tension roller 34 are rotatably connected to rotating plates. The side of the second tension roller 34 away from the first tension roller 33 is provided with a rotating shaft fixedly connected to the rotating plate. The two guide rollers 32, the first tension roller 33, the rotating shaft, and the false warp beam 35 are rotatably connected to the frame 31 along a direction perpendicular to the yarn transport direction. The end of the rotating plate away from the second tension roller 34 is provided with a driving component that drives the rotating plate to rotate along the axis of the rotating shaft. The driving component can be a cylinder, the cylinder body of which is rotatably connected to the frame 31, and the telescopic end of the cylinder is rotatably connected to the rotating plate.

[0046] Reference Figure 4 A frame 4 is provided on the side of the roller assembly 3 near the warping frame 2. The frame 4 is fixedly connected to the machine frame 31. Several elastic spacers 41 are fixed inside the frame 4. The elastic spacers 41 are used to limit the movement of the yarn and for cleaning. The elastic spacers 41 can be rubber spacers or silicone spacers, and have a certain degree of elasticity and flexibility. When the yarn passes between two adjacent elastic spacers 41, the elastic spacers 41 can limit the movement of the yarn to prevent it from shaking, and at the same time clean the dust and impurities on the surface of the yarn.

[0047] Reference Figure 5 The yarn output from the guide sleeve 233 of the warping frame 2 passes through the frame 4 and then passes around the lower side of the first guide roller 32, the upper side of the second guide roller 32, the lower side of the false warp roller, the false warp roller counterclockwise, the lower side of the first tension roller 33, the first tension roller 33 counterclockwise, the upper side of the second tension roller 34, and then is fed into the weaving device 1.

[0048] Reference Figure 4 The roller assembly 3 has several selvage tension adjustment components 5 arranged perpendicular to the yarn transport direction on one side near the warping frame 2. Each group of three or more selvage tension adjustment components 5 is fixed to both ends and the middle of the frame 4, respectively. The number of groups is set according to the required number of cuts, ensuring that each cut fabric has specific yarns on both sides. These specific yarn spools are placed below the corresponding selvage tension adjustment components 5. The frame 4 is detachably connected to the machine frame 31 by bolts, and a suitable frame 4 can be selected according to the number of cuts.

[0049] Reference Figure 6The selvage tension adjustment assembly 5 includes a base plate 51, a guide member 52, and two sets of limiting components 53 arranged along the yarn transmission direction. The guide member 52 is located between the two sets of limiting components 53, and the limiting components 53 are installed on the upper surface of the base plate 51. The limiting components 53 are used to limit and adjust the tension of the selvage yarn in the vertical direction, while the guide member 52 guides the selvage yarn and adjusts the tension in the horizontal direction.

[0050] Reference Figure 6 The base plate 51 can be a metal base plate or a plastic base plate, and its shape is usually rectangular. The base plate 51 is fixedly connected to the upper surface of the frame 4 by self-tapping screws. The lower end of the base plate 51 has an integrally formed protruding ring, which together with the base plate 51 forms a groove. A vertical plate is fixed on each side of the upper end of the base plate 51 along the yarn transmission direction, and a guide sleeve 233 is also inserted on the vertical plate. The base plate 51 has two through holes and an arc-shaped groove 511. The arc-shaped groove 511 is coaxial with one of the through holes. The design of the arc-shaped groove 511 allows the guide 52 to rotate within a certain range, thereby realizing flexible adjustment of the yarn tension.

[0051] Reference Figure 6 and Figure 7 The limiting component 53 includes a guide cylinder 531, a lower disc 532, an upper disc 533, an elastic element 534, a clamping element 535, a first bolt 536, and a second bolt 537. The lower disc 532, upper disc 533, and elastic element 534 are sequentially sleeved on the outside of the guide cylinder 531 from bottom to top. The clamping element 535 is located above the guide cylinder 531, and the elastic element 534 is sandwiched between the upper disc 533 and the clamping element 535. The guide cylinder 531 is fixedly connected to the upper end face of the base plate 51. The guide cylinder 531 is generally made of metal or plastic, with a smooth surface to reduce friction with the yarn. The lower disc 532 and upper disc 533 can be metal or plastic discs, and the elastic element 534 can be a spring or other elastic body. By adjusting the position of the clamping element 535, the compression degree of the elastic element 534 can be changed, thereby adjusting the clamping force of the limiting component 53 on the yarn and achieving adjustment of the yarn tension. The clamping member 535 is a plastic product with a raised protrusion integrally formed on the outer wall. The clamping member 535 can be rotated by holding the protrusion. The upper end of the clamping member 535 is provided with a groove, which is used to place the fastening end of the first bolt 536 in the groove to limit the clamping member 535.

[0052] Reference Figure 7 and Figure 8The threaded end of the first bolt 536 passes sequentially from top to bottom through the clamping member 535, guide cylinder 531, and base plate 51 of one of the limiting components 53. The first bolt 536 is coaxially fixedly connected to a first fastener 538. A second fastener 539, threadedly connected to the first bolt 536, is located below the base plate 51. The threaded end of the second bolt 537 passes sequentially from bottom to top through the base plate 51, the guide cylinder 531 of the other limiting component 53, and the clamping member 535. The second bolt 537 is threadedly connected to a third fastener. The first fastener 538 and the third fastener are respectively located between the corresponding clamping member 535 and guide cylinder 531. The second bolt 537 is threadedly connected to the corresponding clamping member 535. The first bolt 536 and the second bolt 537 are used to fix the various components of the limiting component 53, ensuring the stability and reliability of the limiting component 53. The first fastener 538 and the second fastener 539 can be nuts or washers. By tightening or loosening the nuts, the installation state of the limiting component 53 and the clamping force on the yarn can be adjusted.

[0053] Reference Figure 7 A rotating plate 521 is sandwiched between the second fastener 539 and the lower end face of the base plate 51. The rotating plate 521 is rotatably connected to the first bolt 536 along its axis, and the lower end of the guide member 52 is fixedly connected to the upper end face of the rotating plate 521. The rotating plate 521 allows the guide member 52 to rotate around the axis of the first bolt 536, thereby enabling fine adjustment of the yarn tension. The rotating plate 521 can be a metal rotating plate or a plastic rotating plate, and its surface can be smoothed to reduce friction during rotation.

[0054] The installation steps of the limiting component 53, which is coaxial with the arc groove 511, are as follows: Starting from the threaded end of the first bolt 536, the clamping component 535, the first fastener 538, the guide cylinder 531, the elastic component 534, the upper disc 533, and the lower disc 532 are sequentially fitted onto the first bolt 536. Then, the threaded end of the first bolt 536 is inserted into the through hole coaxial with the arc groove 511. Below the base plate 51, the rotating plate 521 and the second fastener 539 are sequentially fitted onto the base plate 51. After adjusting the angle of the rotating plate 521 and the length of the elastic component 534, the first fastener 538 and the second fastener 539 are simultaneously tightened to fix the guide cylinder 531 and the rotating plate 521 to the base plate 51. The lower end of the guide component 52 is fixedly connected to the rotating plate 521 through the arc groove 511 using screws. The upper end of the guide component 52 has an integrally formed retaining ring. By rotating the guide component 52 within the arc groove 511, the tension of the yarn can be finely adjusted, making the tension of the fabric edge more uniform.

[0055] The installation steps of another limiting component 53 are as follows: After the threaded end of the second bolt 537 passes through another through hole upward, the guide cylinder 531, the lower disc 532, the upper disc 533, the third fastener, the elastic element 534 and the clamping element 535 are installed sequentially from bottom to top. First, after tightening the third fastener, the guide cylinder 531 is fixed to the base plate 51. Then, the clamping element 535 is tightened to adjust the length of the elastic element 534.

[0056] Reference Figure 9 The selvage yarn is fed sequentially through the inlet guide sleeve 233 of one selvage tension adjustment component 5, between the lower disk 532 and the upper disk 533 of one limiting component 53, around the guide cylinder 531 extending to the side wall of the guide member 52, extending to between the lower disk 532 and the upper disk 533 of another limiting component 53, around the guide cylinder 531 extending to the upper side of the first tension roller 33 and the second tension roller 34, and then input into the weaving device 1.

[0057] The implementation principle of a bipolar tension-adjustable flexible transmission device applicable to weaving processes in this application embodiment is as follows: This bipolar tension-adjustable flexible transmission device is equipped with several warping frames 2 arranged perpendicular to the yarn transmission direction. Each warping frame 2 includes a support plate 22 and an anti-static guide assembly 23 arranged sequentially along the height direction of the frame body 21. This allows it to be suitable for unwinding yarns of various winding forms, and is compatible with the warping requirements of both internally wound and externally wound packaged yarns. The two pressure rollers 231 in the anti-static guide assembly 23 are arranged along the yarn transmission direction and rotatably connected to the support plate 22. Furthermore, the roller shafts and pressure rollers 231 in the roller shaft assembly 3 near the warping frame 2 end of the weaving device 1 are all made of anti-static material. This improves the accuracy of tension adjustment, meets the special requirements of glass fiber and basalt fiber, reduces static electricity, fly waste, and fuzz, and minimizes the adverse effects of friction between glass fiber and basalt fiber and surfaces such as stainless steel or galvanized rollers. This protects brittle fibers from breakage during warping and improves the quality of the finished product.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
