The braiding device for oxygenated membrane fibers includes a frame, a braiding mechanism, a filament unwinding mechanism, a filament tension detection device, and a filament tension adjusting mechanism. The oxygenated membrane fibers are sequentially conveyed to the braiding mechanism after passing through the filament tension adjusting mechanism and the filament tension detection device. The filament tension adjusting mechanism includes a counterweight storage assembly and a traction component arranged sequentially along the feeding direction of the oxygenated membrane fibers.

Description

Technical Field

[0001] This application relates to the field of oxygenated membrane fiber processing technology, and in particular to an apparatus and method for weaving oxygenated membrane fibers. Background Technology

[0002] Oxygenation membrane fibers are used in medical device manufacturing to provide raw materials for oxygenators. Oxygenation membrane fibers are hollow inside with fixed inner and outer diameters. After being produced through a spinning process, they are wound into coils. During oxygenator assembly, these coiled oxygenation membrane fibers need to be woven into a mat-like membrane for application. However, during the unwinding and weaving process, the hollow state of the oxygenation membrane fibers is easily damaged by excessive stretching, leading to gaps in operation, waste of weaving material, low weaving efficiency, and hindering large-scale production. Summary of the Invention

[0003] Therefore, it is necessary to provide a weaving device and method for oxygen film yarns to address the problem that the hollow state of oxygen film yarns is easily damaged during the unwinding and weaving process, resulting in low production efficiency.

[0004] An embodiment of the first aspect of this application provides a weaving apparatus for oxygenated membrane filaments, comprising:

[0005] rack; and

[0006] Both the braiding mechanism and the membrane fiber unwinding mechanism are mounted on the frame. The membrane fiber unwinding mechanism outputs oxygenated membrane fibers to the braiding mechanism.

[0007] A membrane fiber tension detection device is used to detect the working tension value of the oxygenated membrane fiber;

[0008] The oxygenated membrane filaments are sequentially fed to the weaving mechanism after passing through the membrane filament tension adjustment mechanism and the membrane filament tension detection device.

[0009] The membrane tension adjustment mechanism includes a counterweight storage assembly and a traction component arranged sequentially along the feeding direction of the oxygenated membrane filament. The counterweight storage assembly is used to take in and release the oxygenated membrane filament, and the traction component is used to pull the oxygenated membrane filament.

[0010] When the working tension value of the oxygenated membrane filament is greater than the preset tension value of the oxygenated membrane filament, the traction speed of the traction member increases, thereby accelerating the output of the oxygenated membrane filament at the counterweight storage assembly.

[0011] When the working tension value of the oxygenated membrane filament is less than the preset tension value of the oxygenated membrane filament, the traction speed of the traction member decreases, thereby causing the oxygenated membrane filament at the counterweight storage assembly to decelerate and output.

[0012] In one embodiment, the counterweight storage assembly includes a first guide wheel and a counterweight, and the oxygenated membrane filament is sequentially wound around the first guide wheel, the counterweight, and the traction member;

[0013] When the working tension value of the oxygenated membrane filament is greater than the preset tension value of the oxygenated membrane filament, the counterweight moves close to the line connecting the first guide wheel and the traction member to release the oxygenated membrane filament.

[0014] When the working tension value of the oxygenated membrane filament is less than the preset tension value of the oxygenated membrane filament, the counterweight moves away from the line connecting the first guide wheel and the traction member, and is used to tighten the oxygenated membrane filament.

[0015] In one embodiment, the braiding device for the oxygenated membrane filament further includes a braiding filament unwinding mechanism and a braiding filament tension detection device. The braiding filament unwinding mechanism outputs multiple braiding filaments, which are then conveyed to the braiding mechanism after passing through the braiding filament tension detection device. The braiding filament tension detection device is used to detect the working tension value of the braiding filaments.

[0016] In one embodiment, the braiding device for the oxygenated membrane filament further includes a braid tension adjustment mechanism, through which the braided filament is conveyed to the braid tension detection device.

[0017] In one embodiment, the braid tension adjustment mechanism includes a pressure rod, a support frame, and an adjusting member. Multiple braids are respectively threaded on the pressure rod. The pressure rod is slidably connected to the support frame. The adjusting member is drively connected to the pressure rod. The adjusting member drives the pressure rod to move closer to or away from the braids to adjust the pressure force of the pressure rod on the braids.

[0018] In one embodiment, the weaving mechanism includes a working platform, a fabric weaving mechanism, and a weaving head. The weaving head is disposed on the working platform. The oxygen membrane filaments are threaded through the fabric weaving mechanism. The fabric weaving mechanism drives the oxygen membrane filaments to reciprocate and lay the fabric filaments. The weaving filaments are threaded through the weaving head. The weaving head drives multiple weaving filaments to weave the oxygen membrane filaments.

[0019] In one embodiment, the weaving mechanism further includes at least two straightening mechanisms, which are arranged opposite to each other on both sides of the working platform along the first direction, and the oxygenated film filaments output by the weaving mechanism are wound between the opposite straightening mechanisms.

[0020] In one embodiment, the weaving mechanism further includes a wire clamping mechanism disposed on the side of the work platform, the wire clamping mechanism being used to clamp the end of the oxygenated membrane filament.

[0021] In one embodiment, the weaving mechanism further includes a finished product traction mechanism and a cutting mechanism. The finished product traction mechanism is disposed on the working platform and is used to drive the woven finished product film to move and output. The cutting mechanism is disposed on the side of the working platform and is used to cut and seal the side of the finished product film.

[0022] An embodiment of the second aspect of this application provides a method for weaving oxygenated membrane fibers, based on the aforementioned weaving apparatus for oxygenated membrane fibers, the weaving method comprising:

[0023] Oxygen membrane yarns and braided yarns are available;

[0024] Obtain the working tension value of the oxygenated membrane filament;

[0025] When the working tension value of the oxygen membrane filament is greater than the preset tension value of the oxygen membrane filament, the traction speed of the oxygen membrane filament is increased, and the oxygen membrane filament is released.

[0026] When the working tension value of the oxygen membrane filament is less than the preset tension value of the oxygen membrane filament, the traction speed of the oxygen membrane filament is reduced and the oxygen membrane filament is tightened.

[0027] The oxygenated membrane filaments and the braided filaments are braided.

[0028] The aforementioned oxygenated membrane yarn weaving device incorporates a membrane yarn tension detection device and a membrane yarn tension adjustment mechanism during the process of outputting the yarn from the unwinding mechanism to the weaving mechanism. This allows for real-time monitoring and adaptive adjustment of the oxygenated membrane yarn's tension during weaving, maintaining a relatively stable tension. This reduces excessive stretching of the oxygenated membrane yarn during unwinding and weaving, avoids damage to the hollow state of the yarn, makes the weaving operation smoother, reduces intermittent operation and material waste, and improves production efficiency.

[0044] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0045] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0046] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0047] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0048] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0049] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0050] See Figure 1The figure shows an overall schematic diagram of the oxygenated membrane fiber weaving device according to an embodiment of this application. The oxygenated membrane fiber weaving device provided in one embodiment of this application includes a frame 1, a weaving mechanism 2, a membrane fiber unwinding mechanism 3, a membrane fiber tension detection element 4, and a membrane fiber tension adjusting mechanism 5. Both the weaving mechanism 2 and the membrane fiber unwinding mechanism 3 are mounted on the frame 1. The membrane fiber unwinding mechanism 3 outputs oxygenated membrane fibers 9 to the weaving mechanism 2 for weaving. The membrane fiber tension detection element 4 is used to detect the working tension value of the oxygenated membrane fiber 9, so as to facilitate real-time monitoring of the tension state of the oxygenated membrane fiber 9.

[0051] The oxygenated membrane filaments 9 output from the membrane filament unwinding mechanism 3 are sequentially conveyed to the weaving mechanism 2 after passing through the membrane filament tension adjusting mechanism 5 and the membrane filament tension detection element 4. This allows for adaptive adjustment of the tension of the oxygenated membrane filaments 9 during the weaving process based on tension changes. The membrane filament tension adjusting mechanism 5 includes a counterweight storage assembly 51 and a traction element 52 arranged sequentially along the feeding direction of the oxygenated membrane filaments 9. The counterweight storage assembly 51 has a certain range of motion for winding and unwinding the oxygenated membrane filaments 9, reducing excessive pulling on them. The traction element 52 is used to pull the oxygenated membrane filaments 9 for output.

[0052] When the working tension of the oxygenated filament 9 is greater than its preset tension, i.e., when the oxygenated filament 9 is relatively taut, the traction speed of the traction member 52 increases. This accelerates the output of the oxygenated filament 9 at the counterweight storage assembly 51, allowing more of the oxygenated filament 9 to enter the weaving range of the weaving mechanism 2. This reduces excessive pulling on the oxygenated filament 9 and makes the weaving operation of the weaving mechanism 2 smoother. When the working tension of the oxygenated filament 9 is less than its preset tension, i.e., when the oxygenated filament 9 is relatively slack, the traction speed of the traction member 52 decreases. This slows down the output of the oxygenated filament 9 at the counterweight storage assembly 51, allowing fewer of the oxygenated filament 9 to enter the weaving range of the weaving mechanism 2. This gradually brings the working tension of the oxygenated filament 9 closer to its preset tension, making the working tension of the oxygenated filament 9 more stable and uniform, and facilitating the weaving operation.

[0053] The aforementioned oxygenated membrane yarn weaving device, by adding a membrane yarn tension detection element 4 and a membrane yarn tension adjustment mechanism 5 during the process of outputting the membrane yarn from the unwinding mechanism 3 to the weaving mechanism 2, facilitates real-time monitoring and adaptive adjustment of the tension state of the oxygenated membrane yarn 9 during the weaving process. This maintains a relatively stable tension state for the oxygenated membrane yarn 9, thereby reducing excessive pulling on the oxygenated membrane yarn 9 during the unwinding and weaving process, avoiding damage to the hollow state of the oxygenated membrane yarn 9, making the weaving operation of the oxygenated membrane yarn 9 smoother, reducing intermittent operation and waste of weaving materials, improving production efficiency, and solving the problem of low production efficiency caused by the easy damage to the hollow state of the oxygenated membrane yarn 9 during the unwinding and weaving process.

[0054] In this embodiment, the membrane fiber tension detection element 4 and the membrane fiber tension adjustment mechanism 5 can be installed on the frame 1 between the membrane fiber unwinding mechanism 3 and the weaving mechanism 2 to facilitate a smoother and more continuous laying of the oxygenated membrane fiber 9. The preset tension value of the oxygenated membrane fiber 9 can be set by the weight of the preset counterweight storage component 51 and / or the traction speed of the preset traction component 52. The preset tension value can be, but is not limited to, 0.3N and can be selected according to actual usage needs.

[0055] The traction component 52 can move the oxygen membrane filament 9 by relying on the friction between itself and the oxygen membrane filament 9. Optionally, the traction component 52 may include a rotating wheel, on which the oxygen membrane filament 9 is wound. The rotation of the rotating wheel can move the oxygen membrane filament 9. The driving method of the rotating wheel can be, but is not limited to, servo motor drive, which allows for more flexible and accurate control of the traction speed. The frame 1 can be a frame structure, providing a large layout space. The material of the frame 1 can be, but is not limited to, aluminum or stainless steel. A second guide wheel 41 can be provided on the frame 1. The second guide wheel 41 can be positioned between the membrane filament tension detection component 4 and the weaving mechanism 2. The oxygen membrane filament 9 is sequentially conveyed to the weaving mechanism 2 after passing through the membrane filament tension detection component 4 and the second guide wheel 41. The second guide wheel 41 can guide the oxygen membrane filament 9 and reduce friction, preventing the oxygen membrane filament 9 from turning at too large an angle or changing angle frequently at the membrane filament tension detection component 4, which would affect the detection.

[0056] The membrane fiber unwinding mechanism 3 includes a reel and a servo drive mechanism connected in a transmission relationship. The servo drive mechanism drives the reel to rotate. Using a servo drive method, the unwinding speed of the oxygen membrane fiber 9 can be made stable, accurate, and controllable, which can reduce the stretching and deformation of the oxygen membrane fiber 9 to a certain extent. The reel may include a reel body and an air shaft. The reel body is sleeved on the air shaft, and the servo drive mechanism is connected in a transmission relationship with the air shaft. The reel is mounted using an air shaft, which makes the assembly and disassembly of the reel body more convenient and quick.

[0057] See Figure 1-2 In some embodiments, the counterweight storage assembly 51 includes a first guide wheel 511 and a counterweight 512. The oxygenated membrane filament 9 is sequentially wound around the first guide wheel 511, the counterweight 512 and the traction member 52. That is, the first guide wheel 511 and the traction member 52 can support the oxygenated membrane filament 9. The counterweight 512 is disposed between the first guide wheel 511 and the counterweight 512, and can press the oxygenated membrane filament 9 with its own weight and leave a certain length of oxygenated membrane filament 9, so that the oxygenated membrane filament 9 maintains stable tension.

[0058] When the working tension of the oxygenated filament 9 is greater than its preset tension, the counterweight 512 moves closer to the line connecting the first guide wheel 511 and the traction member 52. This allows the oxygenated filament 9 between the first guide wheel 511 and the traction member 52 to be released and output more quickly with the traction member 52, greatly reducing the pulling force of the braiding mechanism 2 on the oxygenated filament 9 and preventing damage to it. When the working tension of the oxygenated filament 9 is less than its preset tension, the counterweight 512 moves away from the line connecting the first guide wheel 511 and the traction member 52. This helps maintain a stable tension on the oxygenated filament 9 between the first guide wheel 511 and the traction member 52, tightening the oxygenated filament 9 and preventing insufficient tension from affecting the braiding. It also reduces the localized excessive instantaneous tension caused by uneven tension distribution of the oxygenated filament 9.

[0059] In this embodiment, the arrangement of the counterweight 512 can be selected according to actual needs, specifically:

[0060] Optionally, the counterweight 512 may include a first pressure block, which may be, but is not limited to, a column or a wheel. The side of the first pressure block may press against the oxygen membrane fiber 9, and the end of the first pressure block may be slidably connected to the frame 1. Its sliding direction may be along the vertical height direction of the frame 1. The weight of the counterweight 512 may be selected and set according to the preset tension value of the oxygen membrane fiber 9, so that the counterweight 512 can press down and guide the oxygen membrane fiber 9 without damaging the hollow state of the oxygen membrane fiber 9. When the working tension value of the oxygen membrane fiber 9 is greater than or less than the preset tension value of the oxygen membrane fiber 9, the traction member 52 pulls the oxygen membrane fiber 9 to move. The counterweight 512 moves vertically up and down with the movement state of the oxygen membrane fiber 9, thereby keeping the tension of the oxygen membrane fiber 9 stable and avoiding excessive pulling on the oxygen membrane fiber 9.

[0061] Optionally, the counterweight 512 may include a second pressure block and a position drive. The second pressure block presses onto the oxygenated membrane fiber 9 and is connected to the position drive. The position drive can move the second pressure block closer to or away from the line connecting the first guide wheel 511 and the traction member 52. Optionally, the movement direction of the second pressure block can be along the vertical height direction of the frame 1, that is, the position drive can drive the second pressure block to move vertically up and down. The position drive is communicatively connected to the membrane fiber tension detection element 4. When the membrane fiber tension detection element 4 detects that the working tension value of the oxygenated membrane fiber 9 is greater than the preset tension value of the oxygenated membrane fiber 9, the membrane fiber tension detection element 4 will transmit a signal to the position drive and the traction member. The position drive drives the second pressure block closer to the line connecting the first guide wheel 511 and the traction member 52, and the traction speed of the traction member increases, causing the oxygenated membrane fiber 9 wound around the range of the first guide wheel 511 and the traction member 52 to accelerate its output, thereby adjusting the tension of the oxygenated membrane fiber 9. Similarly, the opposite is true.

[0062] The second pressure block can be, but is not limited to, a column or a wheel, and the position drive can be, but is not limited to, a cylinder, a hydraulic cylinder, or a motor coupled with a lead screw and nut. The weight of the counterweight 512 can be adjusted by hooking weights onto the pressure block, making adjustment convenient.

[0063] See Figure 1-2 In some embodiments, the braiding device for the oxygen membrane filaments further includes a braiding unwinding mechanism 6 and a braiding tension detection element 7. The braiding unwinding mechanism 6 outputs multiple braiding filaments 10, which are used to wrap and bind the oxygen membrane filaments 9. After passing through the braiding tension detection element 7, the braiding filaments 10 are conveyed to the braiding mechanism 2. The braiding tension detection element 7 is used to detect the working tension value of the braiding filaments 10. That is, by setting the braiding tension detection element 7, the tension state of the braiding filaments 10 can be detected in real time, avoiding excessive or insufficient tension of the braiding filaments 10 from affecting the braiding operation.

[0064] See Figure 2 In this embodiment, the braided yarn unwinding mechanism 6 includes an unwinding carriage 61 and multiple fixed discs 62. The fixed discs 62 are mounted on the unwinding carriage 61 and are used to hold the wound braided yarns 10. Both the braided yarn tension detector 7 and the membrane yarn tension detector 4 can be tension detectors, which can perform tension detection while also displaying tension and providing a breakage alarm function.

[0065] In some embodiments, the oxygen membrane filament weaving device further includes a filament tension adjusting mechanism 8, through which the filament 10 is fed to the filament tension detection element 7. When the working tension value of the filament 10 is greater than the preset tension value of the filament 10, the filament tension adjusting mechanism 8 reduces the clamping force on the filament 10; when the working tension value of the filament 10 is less than the preset tension value of the filament 10, the filament tension adjusting mechanism 8 increases the clamping force on the filament 10, enabling the filament 10 to perform weaving operations with a more stable tension.

[0066] In this embodiment, the braid tension adjustment mechanism 8 includes a pressure rod 81, a support frame 82, and an adjustment element 83. The support frame 82 can be mounted at both ends of the pressure rod 81 to support it. Multiple braided filaments 10 are respectively threaded onto the pressure rod 81, meaning the pressure rod 81 can adjust the tension of multiple braided filaments 10 together. The pressure rod 81 is slidably connected to the support frame 82, and the adjusting component 83 is drivenly connected to the pressure rod 81. The adjusting component 83 drives the pressure rod 81 to move closer to or further away from the braided filament 10 along its own radial direction, which is used to adjust the pressing force of the pressure rod 81 on the braided filament 10. That is, when the pressure rod 81 moves closer to the braided filament 10, it can increase the pressing force of the pressure rod 81 on the braided filament 10, thereby increasing the tension of the braided filament 10; when the pressure rod 81 moves further away from the braided filament 10, it can decrease the pressing force of the pressure rod 81 on the braided filament 10, thereby reducing the tension of the braided filament 10, so that the tension of the braided filament 10 is more stable, and the weaving process with the oxygen membrane filament 9 is smoother.

[0067] The adjusting member 83 can be connected to the support frame 82 at one end and to the pressure rod 81 at the other end. The adjusting member 83 can move the pressure rod 81 closer to or further away from the braided yarn 10 by its own extension and retraction. The adjusting member 83 may include a cylinder or a hydraulic cylinder, or the adjusting member 83 may also include a motor and a lead screw and nut structure, with the motor and lead screw and nut cooperating to drive the pressure rod 81 to move.

[0068] See Figure 1-2 In some embodiments, the weaving mechanism 2 includes a working platform 21, a yarn-making mechanism 22, and a weaving head 23. The weaving head 23 is mounted on the working platform 21. The working platform 21 may have a first direction and a second direction that are perpendicular to each other. Figure 2 A rectangular coordinate system is established on the working surface of the working platform 21. The Y-axis represents the width of the working platform and can be denoted as the first direction. The X-axis represents the length of the working platform and can be denoted as the second direction. Oxygen membrane filaments 9 are threaded onto the weaving mechanism 22, which is located close to the braiding head 23. The weaving mechanism 22 reciprocates along the first direction on the working platform 21 to weave the filaments. Braiding filaments 10 are threaded onto the braiding head 23. The braiding head 23 drives multiple braiding filaments 10 to weave and bind the oxygen membrane filaments 9. The membrane formed by the weaving of the oxygen membrane filaments 9 and the braiding filaments 10 is output along the second direction. This embodiment can arrange the oxygen membrane filaments 9 in an orderly manner for weaving and binding, making them less prone to confusion.

[0069] In this embodiment, the weaving head 23 may include multiple loop hooks, each corresponding to a braiding thread 10. The loop hooks drive the braiding threads 10 to rise and fall, binding the corresponding oxygenated membrane threads 9. The loop weaving method of the weaving head 23 is similar to the loop weaving method in traditional mat processing, and will not be described in detail here. Of course, the weaving method of the weaving head 23 for the oxygenated membrane threads 9 and the braiding threads 10 can also be the warp and weft weaving method of traditional blankets, which can be selected according to actual needs, as long as the oxygenated membrane threads 9 can be woven into a membrane-like structure by the braiding threads 10.

[0070] In some embodiments, the weaving mechanism 2 further includes at least two straightening mechanisms 24, which are arranged opposite each other on both sides of the working platform 21 along a first direction, and the oxygenated film filaments 9 output by the weaving mechanism 22 are wound between the opposite straightening mechanisms 24.

[0071] In this embodiment, the straightening mechanism 24 may include a stop bar and a drive member. The drive member is connected to the stop bar and can drive the stop bar to move up and down along the vertical direction of the working platform 21. When the yarn-laying mechanism 22 moves the oxygen film yarn 9 towards one side of the first direction to the corresponding straightening mechanism 24, the drive member drives the stop bar to block the yarn-laying path of the oxygen film yarn 9. The oxygen film yarn 9 can be wrapped around the stop bar to form an inflection point. Then, the yarn-laying mechanism 22 can move the oxygen film yarn 9 towards the other side of the first direction to prevent the oxygen film yarn 9 from loosening and shifting due to the change in the direction of the yarn-laying mechanism 22. After the braiding head 23 weaves the section of oxygen film yarn 9 with the braiding yarn 10, the drive member drives the stop bar to move up and down to release the section of oxygen film yarn 9, and then repeats the yarn-laying action in cooperation with the yarn-laying mechanism 22. Alternatively, the straightening mechanism 24 may include a robotic arm positioned opposite to the work platform 21. After the oxygenated membrane filament 9 is delivered to the work platform 21, the robotic arm can smooth and flatten the oxygenated membrane filament 9 on both sides of the work platform 21.

[0072] See Figure 1-2 In some embodiments, the weaving mechanism 2 further includes a wire clamping mechanism 25, which is disposed on the side of the working platform 21. The wire clamping mechanism 25 is used to clamp the end of the oxygen film filament 9 to facilitate clamping and fixing the end of the oxygen film filament 9, thereby facilitating the initial weaving operation. In this embodiment, the wire clamping mechanism 25 may be, but is not limited to, a column or a claw, and can be selected according to actual needs, as long as it can clamp and fix the end of the oxygen film filament 9.

[0073] See Figure 2-3 In some embodiments, the weaving mechanism 2 further includes a finished product traction mechanism 26 and a cutting mechanism 27. The finished product traction mechanism 26 is disposed on the work platform 21 to facilitate the movement and output of the woven finished film. See also Figure 3The arrow indicates the cutting direction of the cutting mechanism 27. The cutting mechanism 27 is located on the side of the working platform 21 so that the side of the finished membrane can be cut and sealed during the process of the finished product traction mechanism 26 driving the finished membrane to move and output, thereby cutting the oxygenated membrane filaments 9 on the finished membrane into multiple segments.

[0074] In this embodiment, the cutting mechanism 27 may be, but is not limited to, an ultrasonic cutting and sealing machine. There may be two cutting mechanisms 27, which are respectively located on both sides of the working platform 21.

[0075] In some embodiments, the oxygenated membrane filament weaving device may further include a control system. The control system may include a PLC controller and a touch screen that are communicatively connected. The touch screen is used to display tension data. The specific structure of the control system is similar to that of the prior art and will not be described in detail here. The control system can be communicatively connected to the weaving mechanism 2, the membrane filament unwinding mechanism 3, the membrane filament tension detection element 4, and the braided filament tension detection element 7, and can display and monitor the tension status of the oxygenated membrane filament 9 and the braided filament 10.

[0076] See Figure 1-2 The weaving device for the oxygen-coated film filaments may further include a finished product storage mechanism 11 and a winding mechanism 12. The finished product storage mechanism 11 may be a liftable roller mechanism, capable of tensioning and storing the finished film to a certain extent. The winding mechanism 12 is used to wind and store the finished film. The winding mechanism 12 may include a cylinder and a rotating shaft. The cylinder is fitted onto the rotating shaft, which may be, but is not limited to, an air shaft, to facilitate the installation and removal of the cylinder.

[0077] Another embodiment of this application provides a method for weaving oxygenated membrane fibers, based on the above-described apparatus for weaving oxygenated membrane fibers. The weaving method includes:

[0078] Oxygen membrane filament 9 and braided filament 10 are provided;

[0079] Obtain the working tension value of oxygen membrane fiber 9;

[0080] When the working tension value of the oxygen membrane filament 9 is greater than the preset tension value of the oxygen membrane filament 9, the traction speed of the oxygen membrane filament 9 is increased and the oxygen membrane filament 9 is released so that more oxygen membrane filament 9 can enter the weaving range, thereby reducing the excessive pulling of the oxygen membrane filament 9.

[0081] When the working tension value of the oxygenated membrane filament 9 is less than the preset tension value of the oxygenated membrane filament 9, the traction speed of the oxygenated membrane filament 9 is reduced and the oxygenated membrane filament 9 is tightened, so that less oxygenated membrane filament 9 enters the weaving range, so that the working tension value of the oxygenated membrane filament 9 gradually approaches the preset tension value of the oxygenated membrane filament 9, making the working tension value of the oxygenated membrane filament 9 more stable and uniform.

[0082] The oxygen membrane filament 9 and the braided filament 10 are braided.

[0083] With this configuration, this embodiment monitors and adjusts the tension of the oxygen membrane yarn 9 in real time during the unwinding and weaving process, maintaining a relatively stable tension state for the oxygen membrane yarn 9. This reduces excessive stretching of the oxygen membrane yarn 9 during unwinding and weaving, avoids damage to the hollow state of the oxygen membrane yarn 9, makes the weaving operation of the oxygen membrane yarn 9 smoother, reduces intermittent operation and waste of weaving materials, and improves production efficiency.

[0084] In summary, the weaving method of oxygen membrane fibers is explained in conjunction with the weaving device for oxygen membrane fibers:

[0085] The rolled oxygen membrane filaments 9 are placed at the membrane filament unwinding mechanism 3. The oxygen membrane filaments 9 released from the membrane filament unwinding mechanism 3 are sequentially transported to the filament laying mechanism 22 via the first guide wheel 511, the counterweight 512, the traction component 52, the membrane filament tension detection component 4, and the second guide wheel. During the first filament laying, the filament laying mechanism 22 transports the oxygen membrane filaments 9 to the filament clamping mechanism 25. The filament clamping mechanism 25 clamps the end of the oxygen membrane filaments 9. Then, the filament laying mechanism 22 drives the oxygen membrane filaments 9 to reciprocate between the corresponding straightening mechanisms 24 to lay the filaments. The rolled braided yarn 10 is placed at the braided yarn unwinding mechanism 6. The braided yarn 10 output from the braided yarn unwinding mechanism 6 is then conveyed to the braiding head 23 after passing through the braided yarn tension adjustment mechanism 8 and the braided yarn tension detection device 7. The braiding head 23 drives the braided yarn 10 to braid and bind the oxygen membrane yarn 9. The oxygen membrane yarn 9 and the braided yarn 10 are conveyed in sequence to form a loop and form a finished film. The finished film traction mechanism 26 drives the finished film to be output, and the cutting mechanism 27 cuts and seals both sides of the finished film to divide the oxygen membrane yarn 9 into multiple segments of fixed length. Finally, the finished film is wound up at the winding mechanism 12.

[0086] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
