Description

Technical Field

[0001] This application relates to the field of warping machine technology, and in particular to a warping and winding device for aramid yarn based on constant contact pressure control. Background Technology

[0002] Aramid yarn is a high-performance fiber material that is widely used in many fields such as aerospace, defense, transportation, and communication cables. In the production process of aramid yarn, warping and winding is a key process, and its forming quality directly affects the subsequent processing and performance.

[0003] A search revealed an existing patent (publication number: CN219772369U) disclosing a warping machine, relating to the field of textile equipment. The machine includes a frame for mounting a yarn separating plate and a yarn collecting frame. A winding rod is rotatably mounted on the frame, located on the side of the yarn collecting frame away from the yarn separating plate. The winding rod is used for winding yarn, and two limiting plates are movably mounted on the winding rod, through which the winding rod passes. The two limiting plates together limit the winding width of the yarn. An adjustment component is connected to each of the two limiting plates, used to adjust the position of the limiting plates on the winding rod. When the required yarn widths are different, the adjustment components adjust the positions of the two limiting plates on the winding rod, thereby adjusting the distance between the two limiting plates and thus adjusting the winding width when winding the yarn. This process reduces the time and manpower required to remove and replace the warp beam, improving work efficiency. In the process of developing this application, the inventors discovered the following problems with the existing technology:

[0004] While existing warping machines can control the winding width of yarn by adjusting the position of the limit plate during the winding process, pressure control during the winding process is crucial for high-performance fiber materials such as aramid yarn in actual production. However, most existing warping machines lack constant contact pressure control functions, making it impossible to monitor and adjust the winding pressure in real time during the winding process, which makes it difficult to meet the high precision requirements of aramid yarn warping. In addition, the cleaning of the yarn separating plate during the winding process of existing warping machines often requires manual operation, which is not only inefficient but also makes it difficult to guarantee the cleaning effect, easily affecting the winding quality of the yarn.

[0005] Therefore, in response to the aforementioned technical problems, a warping and winding device for aramid yarn based on constant contact pressure control is proposed. Summary of the Invention

[0006] To address the aforementioned issues, this application provides an aramid yarn warping and winding device based on constant contact pressure control.

[0007] This application provides a warping and winding device for aramid yarn based on constant contact pressure control, which adopts the following technical solution:

[0008] A warping and winding device for aramid yarn based on constant contact pressure control includes a base plate placed on the ground or a table and two machine bodies. The bottoms of the two machine bodies are fixedly mounted on the top of the base plate. A control panel is installed on one of the machine bodies. A first protective frame is fixedly mounted on one side of one of the machine bodies. An auxiliary cleaning winding component is fixedly installed inside the first protective frame. Slide grooves are provided on the inner sides of the two machine bodies. Mounting groove one and mounting groove two are respectively opened on the other side of one of the machine bodies and on the other side of the other machine body. An angle-adjustable yarn breakage positioning component is installed inside mounting groove two. Two telescopic rods are fixedly mounted on the top of the base plate. Mounting blocks are fixedly mounted on the top of the two telescopic rods. An adjusting roller for adjusting the winding pressure of the aramid yarn is rotatably mounted between the two mounting blocks.

[0009] Preferably, a pressure sensor is fixedly installed on the inner wall of the bottom of the slide, a movable block is slidably arranged inside the slide, a spring is fixedly connected between the bottom of the movable block and the inner wall of the bottom of the slide, a pressure rod is fixedly installed at the bottom of the movable block and the pressure rod is located above the pressure sensor, and a connecting frame is fixedly connected between the two movable blocks.

[0010] By adopting the above technical solution, the aramid yarn will exert a certain pressure on the connecting frame, causing the moving block to slide in the groove and compress the spring. The pressure rod then moves downward and exerts pressure on the pressure sensor. The pressure sensor can monitor the pressure applied by the pressure rod in real time and convert the pressure signal into an electrical signal and transmit it to the control panel. The control panel controls the position of the adjusting roller according to the received pressure signal, thereby achieving precise adjustment of the aramid yarn winding pressure and maintaining constant contact pressure.

[0011] Preferably, two L-shaped mounting brackets are fixed to the top of the base plate, a yarn guide rod is fixedly connected between the two L-shaped mounting brackets, a fixing groove is opened on each of the two L-shaped mounting brackets, and a second protective frame is fixed to the outer side of each of the two L-shaped mounting brackets.

[0012] By adopting the above technical solution, the setting of the yarn guide rod can provide a stable guiding effect for the aramid yarn, ensure that the yarn maintains a straight movement during the winding process, avoid deviation or entanglement, and improve the quality of winding.

[0013] Preferably, a yarn separating plate is provided inside the fixing groove, and a second spring is fixedly connected between the top of the fixing groove and the top of the yarn separating plate. The yarn separating plate is provided with yarn separating holes for yarn separating.

[0014] By adopting the above technical solution, it is ensured that each yarn can be evenly distributed through the yarn separating hole, effectively preventing yarn breakage or overlap caused by uneven tension during winding, and further improving the consistency and stability of winding.

[0015] Preferably, a motor is fixedly installed inside the mounting slot, and a screw with a threaded groove on the outer side is installed at the output end of the motor. The other end of the screw is rotatably installed on the other side of the other machine body, and an anti-rotation rod is fixedly installed between the two machine bodies.

[0016] By adopting the above technical solution, the motor can drive the screw to rotate after starting. Since the screw has a threaded groove on the outside and the other end is rotatably mounted on another machine body, and an anti-rotation rod is fixed between the two machine bodies, the rotation of the screw will cause the slider to move linearly on the screw and the anti-rotation rod. This design allows the yarn collecting frame to be adjusted in position between the two machine bodies to adapt to different winding requirements.

[0017] Preferably, a slider is slidably provided on the outer side of the screw and the anti-rotation rod, the slider is threadedly connected to the screw, and a yarn collecting frame is fixedly installed on the top of the slider.

[0018] By adopting the above technical solution, the yarn collecting frame can move smoothly in a straight line on the screw and anti-rotation rod under the drive of the slider, thereby flexibly adjusting its position according to the actual winding situation, ensuring that the aramid yarn can be accurately collected and wound, and improving the adaptability and winding efficiency of the device.

[0019] Preferably, the auxiliary cleaning winding assembly includes a second motor and a rotating shaft. The second motor is fixedly installed inside the first protective frame. One end of the rotating shaft is installed at the output end of the second motor, and the other end of the rotating shaft passes through the two machine bodies in sequence. A winding roller for winding aramid yarn is installed on the outside of the rotating shaft, and the winding roller is located between the two machine bodies. A mounting shaft is rotatably connected between the second protective frame and the L-shaped mounting frame. A teardrop-shaped protrusion is fixed on the outside of the mounting shaft, and the teardrop-shaped protrusion is located below the yarn separating plate.

[0020] By adopting the above technical solution, the teardrop-shaped protrusion will rotate continuously as the mounting shaft rotates. Its special shape can vibrate and clean the yarn separating plate to a certain extent during the rotation. The vibration can effectively prevent yarn fuzz, wax residue and dust from accumulating in the yarn separating hole and keep the yarn channel smooth.

[0021] Preferably, a timing pulley is fixedly installed on both the outer side of the rotating shaft and the outer side of the mounting shaft, and a timing belt is engaged between the two timing pulleys.

[0022] By adopting the above technical solution, the synchronous pulley on the mounting shaft will also rotate synchronously through the transmission action of the synchronous belt, thereby driving the mounting shaft to rotate, so that the teardrop-shaped protrusion can continuously vibrate and clean the yarn separating plate. This synchronous transmission design ensures the synchronous operation of the rotating shaft and the mounting shaft, improving the cleaning effect and the stability of the device.

[0023] Preferably, the angle-adjustable yarn breakage positioning component includes a gantry-shaped adjustment frame and a mounting base. The mounting base is rotatably mounted on one side of one of the machine bodies. One end of the gantry-shaped adjustment frame is fixed to the outside of the mounting base. A light strip is installed on the inner wall of the top of the gantry-shaped adjustment frame. A connecting shaft is fixed through the other end of the gantry-shaped adjustment frame.

[0024] By adopting the above technical solution, the gantry-shaped adjustment frame can rotate flexibly around the mounting base as the axis, thereby adjusting its overall angle. The setting of the light strip can provide a clear light source indication when the yarn breaks, making it easy for operators to quickly locate the broken yarn position and improve maintenance efficiency. The connecting shaft is used to connect the gantry-shaped adjustment frame and the subsequent adjustment mechanism to achieve precise angle adjustment.

[0025] Preferably, a knob is fixed at one end of the connecting shaft, and the other end of the connecting shaft is rotatably installed inside the second mounting groove. A turbine is fixed on the outside of the connecting shaft, and a worm gear is rotatably installed inside the second mounting groove. The turbine and the worm gear mesh with each other.

[0026] By adopting the above technical solution, the worm gear transmission design has self-locking properties, which can ensure that the gantry adjustment frame remains stable after being adjusted to the required angle and will not easily deviate in angle due to external factors. This ensures the accuracy and reliability of the light strip in yarn breakage positioning and improves the ease of use and stability of the entire device.

[0027] 1. Compared with the prior art, this aramid yarn warping and winding forming device based on constant contact pressure control can not only achieve effective winding of aramid yarn through an auxiliary cleaning winding component, but also automatically clean the yarn separating plate during the winding process, preventing yarn fuzz, wax residue and dust from accumulating in the yarn separating hole, ensuring smooth yarn passage, improving the quality and efficiency of winding forming, and the micro-oscillation can also reduce the static friction points between the yarn and the yarn separating hole wall, reducing yarn wear.

[0028] 2. Compared with existing technologies, this aramid yarn warping and winding forming device based on constant contact pressure control utilizes an angle-adjustable yarn breakage positioning component, which can quickly and accurately locate the yarn breakage position when the yarn breaks. Through the light source indication of the light strip, the operator can intuitively find the yarn breakage point, thereby carrying out timely maintenance and avoiding production interruption and yarn waste caused by yarn breakage. At the same time, the self-locking design of the worm gear also ensures the stability of the gantry adjustment frame after the angle is adjusted, further improving the reliability and practicality of the device.

[0029] 3. Compared with the existing technology, this aramid yarn warping and winding forming device based on constant contact pressure control realizes real-time monitoring and precise adjustment of aramid yarn winding pressure through the cooperation of pressure sensor and adjusting roller. It effectively avoids problems such as yarn breakage or loose winding caused by excessive or insufficient pressure, ensures the consistency and stability of winding forming, and improves product quality.

[0030] 4. Compared with the existing technology, this aramid yarn warping and winding forming device based on constant contact pressure control provides stable guidance and uniform distribution for aramid yarn through the synergistic effect of the yarn guide rod and the yarn separating plate. It effectively prevents the yarn from deviating, tangling, breaking or overlapping during the winding process, further improving the quality and consistency of winding forming. At the same time, the position of the yarn collecting frame can be flexibly adjusted to adapt to different winding requirements, improving the adaptability and flexibility of the device.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail below.

[0042] A warping and winding device for aramid yarn based on constant contact pressure control includes a base plate 1 placed on the ground or table and two machine bodies 2. The bottoms of the two machine bodies 2 are fixedly mounted on the top of the base plate 1. A control panel 3 is installed on one of the machine bodies 2. A first protective frame 4 is fixed on one side of one of the machine bodies 2. The first protective frame 4 can provide good protection for the internal motor 501, preventing damage from external factors and ensuring the stable operation of the auxiliary cleaning winding assembly 5. The auxiliary cleaning winding assembly 5 is fixedly installed inside the first protective frame 4. Slide grooves 11 are provided on the inner sides of the two machine bodies 2. The other side of one machine body 2 and the other side of the other machine body 2 are respectively provided with a first mounting groove 12 and a second mounting groove 13. An angle-adjustable yarn breakage positioning assembly 6 is installed inside the second mounting groove 13. Two telescopic rods 7 are fixedly mounted on the top of the base plate 1. An mounting block 8 is fixedly mounted on the top of each of the two telescopic rods 7. An adjusting roller 9 for adjusting the winding pressure of the aramid yarn is rotatably mounted between the two mounting blocks 8.

[0043] A pressure sensor 14 is fixedly installed on the inner wall of the bottom of the slide 11. A movable block 16 is slidably arranged inside the slide 11. The slide 11 and the movable block 16 are slidably engaged to prevent the movable block 16 from shifting or falling off during sliding, thus ensuring the accuracy of pressure monitoring. A spring 15 is fixedly connected between the bottom of the movable block 16 and the inner wall of the bottom of the slide 11. A pressure rod 17 is fixed to the bottom of the movable block 16 and is located above the pressure sensor 14. The pressure rod 17 can effectively apply pressure to the pressure sensor 14, ensuring that the pressure sensor 14 can accurately sense the pressure. Due to pressure changes, a connecting frame 18 is fixedly connected between the two moving blocks 16. Two L-shaped mounting brackets 19 are fixedly fixed on the top of the base plate 1, and a yarn guide rod 20 is fixedly connected between the two L-shaped mounting brackets 19. The yarn guide rod 20 is made of high-strength, wear-resistant alloy material, and its surface is finely polished to reduce friction with the yarn and ensure that the yarn moves smoothly during the guiding process. Each of the two L-shaped mounting brackets 19 has a fixing groove 21, and a second protective frame 10 is fixed to the outer side of each of the two L-shaped mounting brackets 19. A yarn separating mechanism is provided inside the fixing groove 21. A spring 22 is fixedly connected between the top of the fixed groove 21 and the top of the yarn separating plate 23. The spring 22 not only provides stable elastic support for the yarn separating plate 23, but also acts as a buffer when the yarn tension changes, preventing the yarn separating plate 23 from being damaged due to excessive force. The yarn separating plate 23 has a yarn separating hole 24 for separating yarn. A motor 25 is fixedly installed inside the mounting groove 12. A screw 26 with a threaded groove on the outside is installed at the output end of the motor 25. The other end of the screw 26 is rotatably installed on the other side of another machine body 2. The two machine bodies 2 An anti-rotation rod 27 is fixedly installed between the two parts. The anti-rotation rod 27 can prevent the slider 28 from rotating during the movement, ensuring that the yarn collecting frame 29 can move smoothly in a straight line. A slider 28 is slidably arranged on the outside of the screw 26 and the anti-rotation rod 27. The slider 28 is threadedly connected to the screw 26. The yarn collecting frame 29 is fixedly installed on the top of the slider 28. The yarn collecting frame 29 is made of lightweight and high-strength aluminum alloy material, which effectively reduces the overall weight while ensuring structural strength, making it easy for the slider 28 to drive it to adjust its position, thereby enabling the warping and winding of aramid yarn.

[0044] The working process of this application is as follows: The aramid yarn is manually passed sequentially through the guide rod 20, the yarn separating hole 24 on the yarn separating plate 23, the adjusting roller 9, and the yarn collecting frame 29, and then wound around to the outside of the auxiliary cleaning winding assembly 5. The device is then activated using the control panel 3. During the winding process of the aramid yarn, the auxiliary cleaning winding assembly 5 can automatically clean the yarn separating plate 23, preventing yarn fuzz, wax residue, and dust from accumulating in the yarn separating hole 24, ensuring a smooth yarn path. The aramid yarn also exerts a certain pressure on the connecting frame 18, causing the moving block 16 to slide within the slide groove 11 and compress the spring 15. The pressure rod 17 moves downwards and exerts pressure on the pressure sensor 14. The pressure sensor 14 can monitor the pressure applied by the pressure rod 17 in real time and convert the pressure signal into an electrical signal, which is transmitted to the control panel 3. The control panel 3 controls the extension and retraction of the telescopic rod 7 based on the received pressure signal, thereby adjusting the height of the adjusting roller 9. The device is designed to precisely adjust the winding pressure of aramid yarn, maintain a constant contact pressure, and prevent yarn quality problems caused by pressure fluctuations. During winding, if a yarn breakage occurs, the angle-adjustable yarn breakage positioning component 6 comes into play, allowing operators to visually identify the breakage point and promptly carry out repairs, avoiding production interruptions and yarn waste caused by yarn breakage. Simultaneously, after the motor 25 starts, it drives the screw 26 to rotate. Since the screw 26 has a threaded groove on its outer side and its other end is rotatably mounted on another machine body 2, and an anti-rotation rod 27 is fixed between the two machine bodies 2, the rotation of the screw 26 causes the slider 28 to move linearly on the screw 26 and the anti-rotation rod 27. The slider 28 drives the yarn collecting frame 29 to move smoothly. The position of the yarn collecting frame 29 can be flexibly adjusted according to the actual winding situation to ensure accurate collection and winding of the aramid yarn, adapting to different winding needs. After the winding work is completed, the operator can turn off the device through the control panel 3.

[0045] The auxiliary cleaning type winding assembly 5 includes a second motor 501 and a rotating shaft 502. The second motor 501 is fixedly installed inside the first protective frame 4. One end of the rotating shaft 502 is installed at the output end of the second motor 501, and the other end of the rotating shaft 502 passes through the two machine bodies 2 in sequence. A winding roller 503 for winding aramid yarn is installed on the outside of the rotating shaft 502 and the winding roller 503 is located between the two machine bodies 2. A mounting shaft 504 is rotatably connected between the second protective frame 10 and the L-shaped mounting frame 19. A teardrop-shaped protrusion 507 is fixed on the outside of the mounting shaft 504. The teardrop-shaped protrusion 507 can drive the yarn separating plate 23 to vibrate slightly. The teardrop-shaped protrusion 507 is located below the yarn separating plate 23. Synchronous pulleys 505 are fixedly installed on the outside of the rotating shaft 502 and the outside of the mounting shaft 504. A synchronous belt 506 is meshed between the two synchronous pulleys 505.

[0046] In use, the second motor 501 starts, driving the rotating shaft 502 to rotate. The winding roller 503 on the outer side of the rotating shaft 502 rotates accordingly, starting the winding operation of the aramid yarn. At the same time, the rotation of the rotating shaft 502 also drives the synchronous pulley 505 on its outer side to rotate. Since the synchronous belt 506 is meshed with the two synchronous pulleys 505, the synchronous pulley 505 on the outer side of the mounting shaft 504 will also rotate synchronously, thereby driving the mounting shaft 504 to rotate. When the mounting shaft 504 rotates, the teardrop-shaped protrusion fixed on its outer side... As 507 rotates continuously, the special shape of the teardrop-shaped protrusion 507 generates a certain degree of vibration on the yarn separating plate 23 during rotation. This vibration can effectively prevent yarn fuzz, wax residue, and dust from accumulating in the yarn separating hole 24, keeping the yarn channel smooth and ensuring that the aramid yarn will not have quality problems due to blockage of the yarn separating hole 24 during the winding process. This improves the quality and efficiency of winding and forming. Moreover, this micro-oscillation can also reduce the static friction points between the yarn and the wall of the yarn separating hole 24, reduce yarn wear, and extend the service life of the yarn.

[0047] The angle-adjustable yarn breakage positioning component 6 includes a gantry-shaped adjustment frame 601 and a mounting base 602. The mounting base 602 is rotatably mounted on one side of one of the machine bodies 2. The mounting base 602 improves the stability of the gantry-shaped adjustment frame 601 when it rotates. One end of the gantry-shaped adjustment frame 601 is fixed to the outside of the mounting base 602. A light strip 603 is installed on the inner wall of the top of the gantry-shaped adjustment frame 601. A connecting shaft 605 is fixed through and fixed to the other end of the gantry-shaped adjustment frame 601. A knob 604 is fixed to one end of the connecting shaft 605. The other end of the connecting shaft 605 is rotatably mounted inside the second mounting groove 13. A worm gear 606 is fixed to the outside of the connecting shaft 605. A worm 607 is rotatably mounted inside the second mounting groove 13. The worm gear 606 and the worm 607 mesh with each other.

[0048] In use, the operator can quickly rotate knob 604, which drives the connecting shaft 605 to rotate. The turbine 606 on the outside of the connecting shaft 605 rotates accordingly. Since the turbine 606 and the worm gear 607 mesh with each other, the rotation of the turbine 606 will drive the worm gear 607 to rotate. At the same time, the gantry-shaped adjustment frame 601 rotates, which can flexibly adjust its overall angle according to actual needs. At this time, the light strip 603 installed on the inner wall of the top of the gantry-shaped adjustment frame 601 lights up, providing a clear light source indicator even in dark environments. Once a yarn breaks, the light and shadow of the yarn will immediately disappear. The operator can intuitively and quickly find the yarn break point and carry out timely repairs, avoiding production interruptions and yarn waste caused by yarn breaks. Moreover, the transmission design between the turbine 606 and the worm gear 607 has self-locking properties, which ensures that the gantry-shaped adjustment frame 601 remains stable after being adjusted to the required angle and will not easily deviate due to external factors. This ensures the accuracy and reliability of the light strip 603 in locating yarn breaks, further improving the reliability and practicality of the device.
