Abstract
Description
Technical Field
[0001] This application relates to the field of textile equipment technology, and in particular to isolation components, tension isolation mechanisms, tension detection methods, and tension adjustment methods. Background Technology
[0002] Textile equipment includes two main categories: spinning and weaving. In the spinning and weaving process, controlling the tension of the yarn is particularly important.
[0003] The inventor previously disclosed a tension isolation mechanism, a tensioning frame with a tension isolation mechanism, and a circular weaving production system in utility model publication number CN217948404U. The system includes a warp frame, a tensioning frame, and a circular loom. Raw yarn is continuously released from the warp frame, passes through the tensioning frame, and moves to the circular loom, where it is woven. The tension isolation mechanism is located on the tensioning frame and includes a tensioning rod and a pressing unit. The yarn passes through the pressing unit, and the tensioning rod and pressing unit apply a pair of opposing forces to the yarn. When the pair of forces are equal in magnitude, the yarn forms a wave shape and is in a state of tension equilibrium.
[0004] However, after practical use and in-depth research, the inventors found that if the yarn itself has good stiffness, the tension isolation mechanism can prevent the pressing unit from falling rapidly when the yarn comes loose or breaks. However, if the yarn itself is soft, the pressing unit will fall rapidly under its own weight when the yarn comes loose or breaks, causing the tension of the moving yarn to drop to zero instantly. This makes it difficult for operators to repair and adjust in time, leading to malfunctions and shutdowns of the circular loom, and further limiting the application range of the tension isolation mechanism. Summary of the Invention
[0005] To address the issue that the tension of the moving yarn instantly drops to zero due to the rapid descent of the pressing unit, making timely maintenance and adjustment impossible for operators, and to improve the limitation of the original tension isolation mechanism to yarns with a certain degree of stiffness, i.e., mainly confined to the field of plastic weaving, this application provides an isolation component, a tension isolation mechanism, a tension detection method, and a tension adjustment method.
[0006] The isolation component, tension isolation mechanism, tension detection method, and tension adjustment method provided in this application adopt the following technical solutions:
[0007] An isolation element is disposed on a tension rod for supporting the isolation element, including an open connector and a wire pressing unit disposed at the open end of the connector. Two wire pressing units are provided, and the wire pressing units are hung on the wire. The two wire pressing units are inclined towards each other and abut against the outer wall of the tension rod that cooperates with them. The wire pressing units and the tension rod press and clamp the wire.
[0008] By adopting the above technical solution, the yarn passes through the pressing unit. The pressing unit and the tensioning rod cooperate, and the distance between the two pressing units is less than the diameter of the tensioning rod. The pressing unit is elastic and can maintain the distance between the two pressing units to less than the diameter of the tensioning rod after the tensioning rod is attached. The tensioning rod supports the pressing unit. At the same time, the yarn is positioned between the pressing unit and the tensioning rod, clamping the yarn and making it adhere to the outer wall of the tensioning rod, forming a wave shape. This maintains stable friction between the yarn and the outer wall of the tensioning rod, ensuring that the yarn at the front is always under tension that meets the process requirements when pulled forward. Even if the tension disappears when the yarn at the rear moves forward, the clamping cooperation between the pressing unit and the tensioning rod maintains the wave shape of the yarn, ensuring that the yarn at the front of the pressing unit is always under tension that meets the process weaving requirements. The yarn at the rear will lose tension when it loses tension. Two scenarios are possible: First, if only a portion of the rear thread has come loose or become slack, it will move forward under the pull of the front thread, gradually tightening and automatically restoring its original tension. Production continues uninterrupted in this cycle, and no defects are generated in the preceding processes. Second, if a thread breaks at the rear end, it will move forward under the pull of the front thread but cannot automatically restore its original tension. An alarm signal is set to be issued the instant the tension at the rear disappears. If the broken end is manually repaired within a set time, restoring the original tension, production will still continue uninterrupted, and no defects will be generated in the preceding processes. If the broken end is not repaired within the set time, the production system will automatically stop to prevent the broken end from crossing the tension isolation mechanism and causing defects in the preceding processes, thus improving product yield. Furthermore, this application is applicable to all tension detection and adjustment involving silk, thread, rope, etc., and is particularly suitable for tension detection and adjustment of silk threads in the textile industry.
[0009] Preferably, the connector and the two pressing units are arranged symmetrically.
[0010] By adopting the above technical solution, the symmetrical arrangement of the connector and the wire pressing unit ensures that when the two wire pressing units cooperate with the tensioning rod, the two contact points on the tensioning rod can remain balanced, which is beneficial to maintaining the balanced tension of the wire.
[0011] Preferably, it also includes a counterweight, which is detachably connected to the connector.
[0012] By adopting the above technical solution, after the counterweight and connector are connected, the weight of the pressing unit meets the process requirements. During the movement of the yarn, the tension of the yarn at the front always meets the needs of the textile process. At this time, the weight of the pressing unit is greater than the vertical component of the yarn tension force. The pressing unit always relies on its own weight to press against the outer wall of the tension rod, and at the same time, it can press the yarn, so that the yarn maintains a wavy movement. The counterweight and connector are easy to assemble and disassemble, and it is convenient to select different weights of counterweights according to the different stiffness and softness of the yarn to adapt to different yarns, such as polyethylene yarn, polypropylene yarn, or cotton yarn, etc., which provides high flexibility. If the vertical component of the tension force is greater than the weight of the pressing unit, it means that the yarn tension exceeds the set tension of the textile process. The yarn is straightened, the pressing unit detaches from the outer wall of the tension rod, and the pressing unit can be set to trigger an alarm and stop the machine to avoid the yarn breaking.
[0013] A tension isolation mechanism with an isolator includes a tensioning frame and a tensioning rod. The forward movement of the wire is powered by a front pull. The tensioning frame is located in the middle of the wire, dividing it into a front wire and a rear wire. The tensioning rod is mounted on the tensioning frame, and the isolator is mounted on the tensioning rod. A wire-pressing unit abuts against the outer wall of the tensioning rod. The wire-pressing unit and the tensioning rod press and clamp the wire. The two wire-pressing units have the same inclination angle relative to the connecting member.
[0014] By adopting the above technical solution, since the inclination angles of the two wire pressing units relative to the connecting parts are the same, that is, the wire pressing unit abuts against the tensioning rod without any external force, at this time, the wire pressing unit relies on its own weight to abut against the tensioning rod. Therefore, the pressure on the wire at the abutting position of the two wire pressing units and the tensioning rod tends to be consistent, that is, the tension of the current section of the wire can be kept consistent and stable. The rear wire, which is pulled forward by the front, becomes the front wire after passing through the tensioning frame until it reaches the front process. When the wire is on the tensioning frame, the operator assembles the isolation part with the tensioning rod and the isolation part with the wire, so that the two abutting points of the two wire pressing units and the tensioning rod are dynamically balanced, ensuring the stability of the clamping position of the wire, and thus keeping the wire in a state of tension balance.
[0015] Preferably, the tensioning frame is also provided with wire support rods, which are symmetrically arranged on both sides of the tensioning rod. The distance between the highest points of the two wire pressing units is less than the diameter of the tensioning rod. The wire is in contact with the outer walls of the two wire support rods, the two wire pressing units and the tensioning rod, so that the wire forms a wavy shape.
[0016] By adopting the above technical solution, as long as the yarn tension does not exceed the tension set in the textile process, the tensioning rod will always apply a supporting force to the isolating element, and the isolating element will always be in contact with the tensioning rod. Simultaneously, the yarn will adhere to the outer wall of the tensioning rod, making the yarn wavy. The wavy yarn generates friction with the contact surfaces of the yarn support rod, the yarn pressing unit, and the tensioning rod. The entire yarn is divided into a front yarn and a rear yarn by the yarn pressing unit. The tension of the front and rear yarns is isolated by the yarn pressing unit, meaning the yarn tensions on both sides of the yarn pressing unit are different. Under normal circumstances, the front yarn pulls the entire yarn forward, while the rear yarn is in a passive, low-tension state of being released. The tension of the thread is not affected by the thread behind it. Even in extreme cases where the tension of the thread behind it is zero, the tension of the thread in front still maintains the tension required by the production process. This reduces the probability of the tension of the thread in front fluctuating or dropping to zero due to various situations such as the thread behind it coming off or breaking, which would cause an immediate shutdown. At the same time, due to the isolation of the thread tension, the defects generated in the process in front are greatly reduced, further improving the quality and yield of production. If the thread tension exceeds the tension set by the process, the thread will be straightened and the pressing unit will detach from the outer wall of the tensioning rod. In this case, the setting alarm device can be used to trigger the alarm of the pressing unit and stop the machine to prevent the thread from breaking.
[0017] Preferably, the angle between the normals of the planes containing the two pressing units is α, where 90° < α < 180°.
[0018] By adopting the above technical solution, the contact area between the wire and the outer wall of the tension rod can be increased as much as possible, and the wavy section of the wire can be lengthened as much as possible, which is conducive to stabilizing the friction between the wire and the tension rod.
[0019] A tension detection method using any one of the above-described tension isolation mechanisms, wherein the tension isolation mechanism is disposed on a moving wire, the isolation element is attached to the wire, and the isolation element abuts against the tensioning rod;
[0020] The tensioning frame is also equipped with a tension detection mechanism, which is located on the rear wire of the isolation member and is used to detect the tension of the rear wire.
[0021] Preferably, the tension detection mechanism includes a tension detection support rod, a first tension detection rod, and a detection switch for cooperating with the first tension detection rod. There are at least two tension detection supports rods, and at least two tension detection supports rods are slidably mounted on the tensioning frame. The first tension detection rod is hung on the wire and located between two adjacent tension detection supports rods. The detection switch is located below the first tension detection rod and is used to trigger an alarm.
[0022] When the rear end of the thread comes loose or breaks, the first tension detection rod moves under its own weight. When the first tension detection rod comes into contact with the detection switch, the detection switch triggers an alarm.
[0023] By adopting the above technical solution, the tensioning rod, tensioning frame, isolator, first tension detection rod, and yarn are assembled and connected, ensuring that the yarn maintains the required tension during weaving as it passes through the tension isolator to become the forward yarn. Simultaneously, the first tension detection rod is hung between two tension detection supports. When the rear yarn loses tension due to detachment or breakage, the first tension detection rod sends an alarm signal to the production system. Due to the cooperation between the pressing unit and the tensioning rod, the forward yarn from the pressing unit to the preceding process sequence is maintained at the required tension. There are two scenarios where the rear yarn loses tension: one is that the rear yarn is not broken, but only partially detached or loosened; in this case, under the pull of the forward yarn... If the thread moves forward, any loose or slack threads gradually tighten and automatically restore their original tension. The first tension detection rod automatically resets. During this cycle, production continues uninterrupted, and no defects are generated in the preceding process. Alternatively, if a thread breaks at the rear, it moves forward under the pull of the preceding thread but cannot automatically restore its original tension. An alarm signal is triggered the moment the tension at the rear disappears. If the broken thread is manually repaired within a set time, restoring the original tension, the first tension detection rod resets, and production continues uninterrupted. No defects are generated in the preceding process. If the broken thread is not repaired within the set time, the first tension detection rod cannot reset, and the production system automatically stops to prevent the broken thread from crossing the tension isolation mechanism and causing defects in the preceding process.
[0024] A tension adjustment method using any one of the above-described tension isolation mechanisms, characterized in that: the tension isolation mechanism is disposed on a movable wire, the isolation element is attached to the wire, and the isolation element abuts against the tensioning rod;
[0025] The tensioning frame is also equipped with a tension adjustment mechanism, which is located on the front thread of the isolator. The tension adjustment mechanism is used to detect the tension of the front thread, and the tension adjustment mechanism and the isolator are dynamically balanced.
[0026] Preferably, the tension adjustment mechanism includes a tension detection rod 2 and a tension detection rod 2. The second tension detection rod 2 is attached to the wire and located between two adjacent tension detection rods 2. The second tension detection rod 2 is used to detect the tension of the wire in front of the isolator.
[0027] When the second tension detection rod detects that the tension value of the front thread is lower than the preset tension value, the weight of the counterweight on the connector is increased, thereby increasing the pressure of the two pressing units pressing the thread against the outer wall of the tensioning rod. The friction between the thread and the pressing unit and the tensioning rod increases, that is, the tension of the front thread increases accordingly.
[0028] When the second tension detection rod detects that the tension value of the front thread is greater than the preset tension value, the weight of the counterweight on the connector is reduced, thereby reducing the pressure of the two pressing units pressing the thread against the outer wall of the tensioning rod. The friction between the thread and the pressing unit and the tensioning rod is reduced, and the tension of the front thread is reduced accordingly.
[0029] By adopting the above technical solution, the tension of the front yarn is monitored in real time through the second tension detection rod. Based on the tension value of the front yarn detected by the second tension detection rod, the pressure of the pressing unit pressing the yarn against the outer wall of the tensioning rod is adjusted by adjusting the weight of the counterweight. This, in turn, adjusts the friction between the yarn, the pressing unit, and the tensioning rod, thus adjusting the tension of the front yarn. This ensures that the tension of the front yarn remains within a relatively precise range during the weaving process, which is beneficial to improving the yield of woven products.
[0030] In summary, this application includes at least one of the following beneficial technical effects:
[0031] 1. The wire passes through the pressing unit, which cooperates with the tensioning rod. The tensioning rod supports the pressing unit, preventing it from falling due to its own weight or the automatically adjusting tension. Simultaneously, it positions the wire between the pressing unit and the tensioning rod, clamping it and ensuring the wire adheres to the outer wall of the tensioning rod, forming a wave shape. This maintains stable friction between the wire and the outer wall of the tensioning rod, ensuring the wire is always under tension as it moves forward, meeting process requirements. Even if the tension disappears as the rear wire moves forward, the clamping cooperation between the pressing unit and the tensioning rod maintains the wave shape, ensuring the tension of the front wire between this tension isolation mechanism and the preceding process always meets process requirements. There are two scenarios where the rear wire loses tension: one is that the rear wire... If a thread breaks, but only partially comes off or loosens, it will move forward under the pull of the preceding thread, gradually tightening and automatically restoring its original tension. Production continues uninterrupted in this cycle, and no defects are generated in the preceding processes. Secondly, if the rear thread breaks, it will move forward under the pull of the preceding thread but cannot automatically restore its original tension. An alarm signal is issued the instant the tension at the rear thread disappears. If the broken end is manually repaired within a set time, restoring the original tension, production will still not stop, and no defects will be generated in the preceding processes. If the broken end is not repaired within the set time, the production system will automatically stop to prevent the broken end from crossing the tension isolation mechanism and causing defects in the preceding processes. This tension isolation mechanism is applicable to all tension detection and adjustment involving silk, thread, rope, etc., and is especially suitable for tension detection and adjustment of silk threads in the textile industry.
[0032] 2. The angle between the normals of the planes containing the two pressing units is α, where 90° < α < 180°. This maximizes the contact area between the wire and the outer wall of the tension rod, and lengthens the wavy section of the wire, thereby stabilizing the friction between the wire and the tension rod.

[0038] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0039] This application discloses an isolation component, such as... Figure 1 and 2 As shown, the device includes a connector 11 with an opening and wire pressing units 12 located at both ends of the opening of the connector 11. The connector 11 is integrally bent into a U-shape, and there are two wire pressing units 12. An isolator 1 is disposed on a tension rod 31 for supporting the isolator 1. The wire 6 passes through the wire pressing units 12. The two wire pressing units 12 are inclined towards each other. The connector 11 and the two wire pressing units 12 are symmetrically arranged. The two wire pressing units 12 abut against the outer wall of the tension rod 31. The wire pressing units 12 and the tension rod 31 press and clamp the wire 6.
[0040] like Figure 1 and 2 As shown, the isolation component 1 also includes a counterweight 13, which is detachably connected to the connector 11. After the counterweight 13 is connected to the connector 11, the weight of the pressing unit 12 meets the process requirements. If the tension of the yarn 6 in front is always in line with the needs of the textile process during the movement of the yarn 6, the weight of the pressing unit 12 is greater than the vertical component of the tension of the yarn 6. The pressing unit 12 always relies on its own weight to abut against the outer wall of the tension rod 31, so that the yarn 6 maintains a wavy shape.
[0041] Depending on the stiffness and softness of the yarn 6, different weights of counterweights 13 are selected to accommodate different yarns 6, such as polyethylene yarn, polypropylene yarn, or cotton yarn, providing high flexibility in use. An alarm device can also be installed. If the vertical component of the tension force exceeds the weight of the pressing unit 12, it indicates that the tension of the yarn 6 exceeds the set tension of the textile process. The yarn 6 is straightened, the pressing unit 12 disengages from the outer wall of the tensioning rod 31, triggering an alarm and stopping the machine to prevent the yarn 6 from breaking.
[0042] This application also discloses a tension isolation mechanism with the aforementioned isolation element, such as... Figure 2 and 3As shown, the system includes a tensioning frame (not shown), a tensioning rod 31, and a wire support rod 32. The tensioning frame is positioned in the middle of the moving wire 6. The forward movement of the wire 6 is powered by a front pull. The tensioning frame, positioned in the middle of the wire 6, divides the wire 6 into a front wire 6 and a rear wire 6. The tensioning rod 31 and the wire support rod 32 are mounted on the tensioning frame, with the wire support rod 32 symmetrically positioned on both sides of the tensioning rod 31. Both the tensioning rod 31 and the wire support rod 32 are round rods. An isolation element 1 is mounted on the tensioning rod 31. A wire pressing unit 12 abuts against the outer wall of the tensioning rod 31. The wire pressing unit 12 and the tensioning rod 31 press and clamp the wire 6. The line connecting the contact points of the two wire pressing units 12 and the tensioning rod 31 is parallel to the direction of wire 6 feeding and moving. Under the combined action of two wire support rods 32, two wire pressing units 12 and tension rod 31, the wire 6 moves in an S-shape along the feeding direction. The wire 6 is in contact with the outer wall of the wire support rod 32 and the tension rod 31 and forms a wave shape, which stabilizes the friction between the wire 6 and the outer wall of the tension rod 31.
[0043] The rear wire 6, pulled forward from the rear by the front, becomes the front wire 6 after passing through the tensioning frame until it reaches the front process. When the wire 6 is on the tensioning frame, the operator assembles the isolation piece 1 with the tensioning rod 31 and the isolation piece 1 with the wire 6, so that the two pressing units 12 and the two contact points of the tensioning rod 31 are balanced with each other, ensuring the stability of the clamping position of the wire 6, and thus keeping the wire 6 in a state of tension balance.
[0044] like Figure 1 As shown, when the two wire pressing units 12 abut against the outer wall of the tensioning rod 31, the distance between the highest points of the two wire pressing units 12 is less than the diameter of the tensioning rod 31, and the included angle between the normals of the planes containing the two wire pressing units 12 is α, 90° < α < 180°. Preferably, α = 150°. This is beneficial for making the wire 6 S-shaped along the feeding direction, and for the wire 6 to form a wave shape at the tension isolation mechanism. This maximizes the contact area between the wire 6 and the outer wall of the tensioning rod 31, and extends the wave-shaped section of the wire 6 as much as possible, thereby stabilizing the friction between the wire 6 and the tensioning rod 31.
[0045] The yarn 6 is continuously released and moves from the warp frame. Because the distance between the highest points of the two pressing units 12 is less than the diameter of the tension rod 31, the tension rod 31 always applies a supporting force to the separator 1. As long as the tension of the yarn 6 does not exceed the tension set in the textile process, the tension rod 31 will always apply a supporting force to the separator 1, and the separator 1 will always be in contact with the tension rod 31. The 150° angle between the normals of the planes containing the two pressing units 12 maximizes the contact area between the yarn 6 and the outer wall of the tension rod 31, and lengthens the wavy section of the yarn 6, thereby stabilizing the friction between the yarn 6 and the tension rod 31.
[0046] The entire thread 6 is divided into a front thread 6 and a rear thread 6 by the pressing unit 12. The tension of the front thread 6 and the rear thread 6 is isolated by the pressing unit 12, that is, the tension of the thread 6 on both sides of the pressing unit 12 is different. Under normal circumstances, the front thread 6 pulls the entire thread 6 forward, while the rear thread 6 is in a low tension state of passive unwinding. The tension of the front thread 6 is not affected by the rear thread 6. Even in extreme cases such as the tension of the rear thread 6 being zero, the front thread 6 can still maintain the tension required by the production process, thereby reducing the probability of the tension of the front thread 6 fluctuating or dropping to zero due to various situations such as the rear thread 6 coming off or breaking, causing an immediate shutdown. At the same time, due to the isolation of the tension of the thread 6, the defects generated in the front process are greatly reduced, further improving the quality and yield of production.
[0047] This application also discloses a tension detection method using the above-described tension isolation mechanism, such as... Figure 2 As shown, the tension isolation mechanism is located on the moving wire 6, the isolation element 1 is attached to the wire 6, and the isolation element 1 abuts against the tension rod 31;
[0048] The tensioning frame is also equipped with a tension detection mechanism, which is located on the rear thread 6 of the isolation element 1. The tension detection mechanism is used to detect the tension of the rear thread 6.
[0049] The tension detection mechanism includes a tension detection rest 7, a first tension detection rod 4, and a detection switch for cooperating with the first tension detection rod 4. At least two tension detection rests 7 are provided, and these rests slidably mounted on the tensioning frame. The first tension detection rod 4 is hung on the thread 6 and positioned between two adjacent tension detection rests 7. The detection switch is located below the first tension detection rod 4 and is used to trigger an alarm. Specifically, when the rear end of the thread 6 detaches or breaks, the first tension detection rod 4 moves under its own weight. When the first tension detection rod 4 contacts the detection switch, the detection switch triggers an alarm.
[0050] The tensioning rod 31, tensioning frame, isolator 1, first tension detection rod 4, and yarn 6 are assembled and connected to ensure that yarn 6 maintains the required tension when passing through the tension isolator to form the front yarn 6. Simultaneously, the first tension detection rod 4 is hung between two tension detection supports 7. When the rear yarn 6 loses tension due to detachment or breakage, the first tension detection rod 4 sends an alarm signal to the production system. Due to the cooperation between the pressing unit 12 and the tensioning rod 31, the front yarn 6 from the pressing unit 13 to the preceding process sequence is always kept in the required tension. There are two situations where the rear yarn 6 loses tension: one is that the rear yarn 6 is not broken, but only partially detached or loosened, in which case the tension of the front yarn 6 will decrease. If the thread 6 moves forward under the pull of the front thread 6 and cannot automatically restore its original tension, the first tension detection rod 4 will automatically reset. During this cycle, production will not stop and no defects will be generated in the preceding process. If the thread 6 at the rear breaks, it will move forward under the pull of the front thread 6 and cannot automatically restore its original tension. The thread 6 is set to issue an alarm signal the moment the tension at the rear disappears. If the broken end is manually repaired within the set time and the original tension is restored, the first tension detection rod 4 will reset. Production will still not stop and no defects will be generated in the preceding process. If the broken end is not repaired within the set time, the first tension detection rod 4 will not reset and the production system will automatically stop to prevent the broken end from crossing the tension isolation mechanism and generating defects in the preceding process.
[0051] The implementation principle of a tension detection method using a tension isolation mechanism in this application embodiment is as follows:
[0052] The pressing unit 12 abuts against the tensioning rod 31 and clamps the thread 6, causing the thread 6 to adhere to the outer wall of the tensioning rod 31 and form a wave shape, ensuring that the thread 6 remains taut during feeding. When the thread 6 comes off or breaks during feeding, the clamping action of the pressing unit 12 and the tensioning rod 31 keeps the thread 6 in a wave shape and maintains the tension required for normal weaving. The remaining thread 6 can then be continuously released, and online self-adjustment is performed during the release process until the tension of this portion of the thread 6 automatically returns to the tension required for normal weaving.
[0053] In this process, if only the thread comes loose, the tension can be restored simply by the self-adjustment of the thread 6; if the thread breaks, the first tension detection rod 44 can trigger an alarm, giving the operator time for maintenance and adjustment, so as to restore the tension required for normal weaving in a timely manner and further reduce the frequency of circular loom shutdowns.
[0054] This application also discloses a tension adjustment method using the above-described tension isolation mechanism, such as... Figure 3As shown, the tension isolation mechanism is located on the moving wire 6, the isolation element 1 is attached to the wire 6, and the isolation element 1 abuts against the tension rod 31;
[0055] The tensioning frame is also equipped with a tension adjustment mechanism, which is located on the front thread 6 of the isolation element 1. The tension adjustment mechanism is used to detect the tension of the front thread 6, and the tension adjustment mechanism and the isolation element 1 are dynamically balanced.
[0056] The tension adjustment mechanism includes a tension detection rod 2 8 and a second tension detection rod 5. The second tension detection rod 5 is attached to the wire and located between two adjacent tension detection rods 2 8. The second tension detection rod 5 is used to detect the tension of the wire 6 in front of the isolation member 1.
[0057] When the second tension detection rod 5 detects that the tension value of the front wire 6 is lower than the preset tension value, the weight of the counterweight block 13 on the connector 11 is increased, thereby increasing the pressure of the two wire pressing units 12 pressing the wire 6 against the outer wall of the tensioning rod 31. The friction between the wire 6 and the wire pressing unit 12 and the tensioning rod 31 increases, that is, the tension of the front wire 6 increases accordingly.
[0058] When the second tension detection rod 5 detects that the tension value of the front wire 6 is greater than the preset tension value, it reduces the weight of the counterweight 13 on the connector 11, thereby reducing the pressure of the two wire pressing units 12 pressing the wire 6 against the outer wall of the tensioning rod 31. The friction between the wire 6 and the wire pressing unit 12 and the tensioning rod 31 decreases, and the tension of the front wire 6 decreases accordingly.
[0059] Tension adjustment can be performed manually or automatically. Manual adjustment: When the tension of the front wire 6 is less than the preset tension value, the weight of the counterweight 13 on the connector 11 can be increased, thereby increasing the pressure of the two wire pressing units 12 pressing the wire 6 against the outer wall of the tensioning rod 31. This increases the friction between the wire 6 and the wire pressing units 12 and the tensioning rod 31, thus increasing the tension of the front wire 6. Conversely, when the second tension detection rod 5 detects that the tension of the front wire 6 is greater than the preset tension value, the weight of the counterweight 13 on the connector 11 can be reduced, thereby decreasing the pressure of the two wire pressing units 12 pressing the wire 6 against the outer wall of the tensioning rod 31. This reduces the friction between the wire 6 and the wire pressing units 12 and the tensioning rod 31, thus decreasing the tension of the front wire 6.
[0060] If automatic adjustment is selected, an automatic tension adjuster can be provided below the connector 11. The second tension detection rod 5 is electrically connected to the automatic tension adjuster. When the second tension detection rod 5 detects that the tension value of the thread 6 is outside the preset tension value range, it sends a signal to the automatic tension adjuster. The automatic tension adjuster adjusts the pressure of the pressing unit 12 on the thread 6 according to the set program, thereby adjusting the friction between the thread 6 and the outer wall of the tensioning rod 31 and the wire support rod 32, thereby adjusting the tension of the thread 6 itself in the reverse direction.
[0061] The implementation principle of a tension adjustment method using a tension isolation mechanism in this application embodiment is as follows:
[0062] The tension of the front yarn 6 is monitored in real time by the second tension detection rod 5. Based on the tension value of the front yarn 6 detected by the second tension detection rod 5, the weight of the counterweight 13 is adjusted to adjust the pressure of the pressing unit 12 pressing the yarn 6 against the outer wall of the tension rod 31, thereby adjusting the friction between the yarn 6 and the pressing unit 12 and the tension rod 31, that is, adjusting the tension of the front yarn 6. This ensures that the tension of the front yarn 6 is always kept within a relatively precise range when it enters the weaving process, which is beneficial to improving the yield of the woven products.
[0063] Example 2:
[0064] The difference between this embodiment and Embodiment 1 is that: Figure 4 As shown, the tension detection method using the tension isolation mechanism is used in conjunction with the tension adjustment method.
[0065] The system includes an isolator 1 mounted on a tensioning frame, a tension detection mechanism, and a tension adjustment mechanism. The isolator 1 is connected to the tensioning rod 31 and is attached to the moving yarn 6. The isolator 1 divides the yarn 6 into a front yarn 6 and a rear yarn 6. The tension detection mechanism is installed on the rear yarn 6 to detect whether the rear end of the rear yarn 6 has detached or broken, and to enable the rear yarn 6 to self-adjust during continuous movement, so that the rear yarn 6 becomes the front yarn 6 after passing the isolator, and at this time the front yarn 6 has the tension required by the process. The tension adjustment mechanism is installed on the front yarn 6 to cooperate with the isolator 1 to detect and dynamically adjust the tension of the front yarn 6, further controlling the tension of the yarn entering the textile processing area to be within a relatively stable range, so that the front yarn 6 always maintains the tension value required by the process when entering the textile processing area.
[0066] The tension detection method and the tension adjustment method are used in combination. Not only can they detect and adaptively adjust the tension of the thread 6 in time when the thread 6 breaks or comes loose, so that the thread 6 can automatically restore its tension; at the same time, when the thread 6 passes through the isolation piece 1 to become the front thread 6, the dynamic cooperation between the tension adjustment mechanism and the isolation piece 1 makes the tension accuracy of the thread 6 entering the textile processing area more stable, thereby preventing defects from occurring in the preceding process and greatly improving the yield of the processed products.
[0067] 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.
