Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and more specifically, to a method and system for preventing uneven wear in texturing machines based on dynamic stroke adjustment. Background Technology

[0002] The texturing machine yarn guide anti-wear system is an intelligent textile machinery control system specifically designed to solve the problem of uneven yarn wear caused by the fixed stroke during the production process of a texturing machine (false twist texturing machine). Through real-time monitoring, dynamic adjustment, and intelligent control technology, this system achieves uniform yarn wear on the yarn guide, extending equipment life and improving product quality.

[0003] The current texturing machine's wire transfer mechanism has a fixed stroke; it uses a wire transfer motor to drive a cam, turning the rotary operation into a reciprocating motion.

[0004] The existing wire transfer mechanism has a fixed stroke, which causes the wire to wear at a fixed position on the guide wheel. In particular, the wire stays on both sides of the reciprocating motion for the longest time, resulting in the most severe wear on the guide wheel on both sides and affecting its service life. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a method and system for preventing uneven wear of texturing machine yarn shifting based on dynamic stroke adjustment, so as to solve the problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] A texturing machine wire shifting and anti-wear method based on dynamic stroke adjustment includes the following steps:

[0008] S1. The controller controls the motor to rotate forward and reverse at a constant speed through the frequency converter. The motor drives the lead screw to switch back and forth between forward and reverse rotation.

[0009] S2. When the lead screw rotates forward and backward, it will drive the slider to move back and forth along the guide rail, and the guide wheel will be driven to move back and forth.

[0010] S3. During the reciprocating motion of the guide wheel, distance sensor one and distance sensor two will be activated by the controller.

[0011] S4. The distance sensor will detect the distance between the fixing bar and the guide wheel in real time and send it to the difference calculation module.

[0012] S5. Distance sensor 2 will detect the distance between the guide wheel and the inner right side wall of the base in real time and send it to the controller.

[0013] S6. After receiving the data, the difference calculation module will subtract the distance detected by the distance sensor from the distance between the guide wheel and the fixing bar when it is not in use.

[0014] S7. If a difference occurs, the difference calculation module will send the difference data to the wear analysis module.

[0015] S8. If no difference is found, it will work normally.

[0016] S9. After a difference occurs, the wear analysis module will analyze the severity of the wear based on the size of the difference data and generate the required frequency conversion value for motor one. The required frequency conversion value will be sent to the controller.

[0017] S10, The controller will simultaneously receive the distance between the guide wheel and the inner right side wall of the base, as well as the value of the motor frequency conversion to be applied at that position;

[0018] S11. The controller will input the frequency conversion values ​​of the motor under different position states into the drive data storage module for storage.

[0019] S12. In subsequent use, the controller will control the inverter in real time according to the frequency conversion values ​​of motor 1 stored in the drive data storage module under different position states.

[0020] S13. When the severely worn part of the guide wheel moves to the yarn position, the frequency converter will increase the speed of the motor to reduce the contact time between the yarn and the guide wheel.

[0021] S14. After the normally worn part of the guide wheel moves to the yarn position, the motor will rotate at a constant speed to maintain the initial speed of the guide wheel.

[0022] This solution also provides a texturing machine wire shifting and anti-wear system based on dynamic stroke adjustment, including a base. A lead screw is rotatably connected to the inner side of the base. A motor is fixedly connected to the right side of the base. The output shaft of the motor is fixedly connected to the lead screw. A slider with a threaded connection is fitted onto the lead screw. A guide rail is fixedly connected to the inner bottom wall of the base. The bottom of the slider is slidably connected to the guide rail. A bracket is connected to the top of the slider. A wire guide wheel is rotatably connected to the inner side of the bracket. A fixing strip is fixedly connected to the inner side of the base. A distance sensor is fixedly connected to the top of the fixing strip. A distance sensor is also fixedly connected to the inner side of the base. Second, a controller and a frequency converter are fixedly connected to the left side of the base. The controller integrates a difference calculation module, a wear analysis module, and a drive data storage module. The output of the controller is connected to the frequency converter, the output of the frequency converter is connected to the motor, the output of the distance sensor is connected to the difference calculation module, the output of the distance sensor is connected to the controller, the output of the difference calculation module is connected to the wear analysis module, the output of the wear analysis module is connected to the controller, and the controller is bidirectionally connected to the drive data storage module.

[0023] As a further description of the above technical solution:

[0024] A second motor is fixedly connected to the right side of the bracket, and the output shaft of the second motor is fixedly connected to the guide wheel. A second frequency converter is fixedly connected to the left side of the base, and the input terminal of the second frequency converter is connected to the controller signal, and the output terminal of the second frequency converter is connected to the second motor signal.

[0025] As a further description of the above technical solution:

The inner wall of the groove has an installation groove, and a fan is embedded in the inner wall of both installation grooves. The input end of the fan is connected to the controller signal. The inner top wall of the groove has air intake grooves arranged at equal intervals.

[0027] As a further description of the above technical solution:

[0028] The base has air outlet slots on both the front and back, and both air outlet slots are square.

[0029] Compared with the prior art, the advantages of this invention are:

[0030] This solution can detect the wear condition of the guide wheel and locate the wear position. When the severely worn part of the guide wheel moves to the yarn position, the frequency converter will increase the speed of the motor to reduce the contact time between the yarn and the guide wheel, thereby effectively slowing down the wear of the severely worn part. When the normally worn part of the guide wheel moves to the yarn position, the motor will rotate normally at a constant speed to maintain the initial speed of the guide wheel. By dynamically adjusting the stroke of the guide wheel according to the wear condition, the uneven wear of the guide wheel can be effectively reduced, thus extending the service life of the equipment.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0040] Please see Figures 1-6 In this invention, the method for preventing uneven wear in a texturing machine based on dynamic stroke adjustment includes the following steps:

[0041] S1. Controller 11 controls motor 3 to rotate forward and reverse at a constant speed through frequency converter 12. Motor 3 drives lead screw 2 to switch back and forth between forward and reverse rotation.

[0042] S2, the forward and reverse rotation of the lead screw 2 will drive the slider 4 to move back and forth along the guide rail 5, and the guide wheel 7 will be driven to move back and forth left and right;

[0043] S3. During the reciprocating motion of the guide wheel 7, distance sensor 9 and distance sensor 10 will be activated by controller 11.

[0044] S4. Distance sensor 9 will detect the distance between the fixing strip 8 and the guide wheel 7 in real time and send it to the difference calculation module 13;

[0045] S5, Distance sensor 2 10 will detect the distance between guide wheel 7 and the inner right side wall of base 1 in real time and send it to controller 11;

[0046] S6. After receiving the data, the difference calculation module 13 will subtract the distance detected by the distance sensor 9 from the distance between the guide wheel 7 and the fixing bar 8 when the device is not in use.

[0047] S7. If a difference occurs, the difference calculation module 13 will send the difference data to the wear analysis module 14.

[0048] S8. If no difference is found, it will work normally.

[0049] S9. After a difference occurs, the wear analysis module 14 will analyze the severity of the wear based on the size of the difference data and generate the required frequency conversion value for the motor 3. The required frequency conversion value will be sent to the controller 11.

[0050] S10 and controller 11 will simultaneously receive the distance between guide wheel 7 and the inner right side wall of base 1, as well as the value of frequency conversion of motor 3 at that position;

[0051] S11, the controller 11 will input the frequency conversion values ​​of motor 3 required under different position states into the drive data storage module 15 for storage;

[0052] S12. In subsequent use, the controller 11 will control the inverter 12 in real time according to the frequency conversion values ​​of motor 3 stored in the drive data storage module 15 under different position states.

[0053] S13. When the severely worn part of the guide wheel 7 moves to the yarn position, the frequency converter 12 will increase the speed of the motor 3 to reduce the contact time between the yarn and the guide wheel 7.

[0054] S14. When the normally worn part of the guide wheel 7 moves to the yarn position, the motor 3 will rotate at a constant speed to maintain the initial speed of the guide wheel 7.

[0055] This invention also provides a texturing machine wire shifting anti-wear system based on dynamic stroke adjustment:

[0056] The system includes a base 1, a lead screw 2 rotatably connected to the inner side of the base 1, a motor 3 fixedly connected to the right side of the base 1, the output shaft of the motor 3 fixedly connected to the lead screw 2, a slider 4 threadedly connected to the lead screw 2, a guide rail 5 fixedly connected to the inner bottom wall of the base 1, the bottom of the slider 4 slidably connected to the guide rail 5, a bracket 6 connected to the top of the slider 4, a guide wheel 7 rotatably connected to the inner side of the bracket 6, a fixing strip 8 fixedly connected to the inner side of the base 1, a distance sensor 9 fixedly connected to the top of the fixing strip 8, a second distance sensor 10 fixedly connected to the inner side of the base 1, and a controller 11 and a frequency converter fixedly connected to the left side of the base 1. The controller 11 integrates a difference calculation module 13, a wear analysis module 14, and a drive data storage module 15. The output of the controller 11 is connected to the frequency converter 12, the output of the frequency converter 12 is connected to the motor 3, the output of the distance sensor 9 is connected to the difference calculation module 13, the output of the distance sensor 10 is connected to the controller 11, the output of the difference calculation module 13 is connected to the wear analysis module 14, the output of the wear analysis module 14 is connected to the controller 11, and the controller 11 has a bidirectional signal connection with the drive data storage module 15.

[0057] In this invention, during use, the controller 11 controls the motor 3 to rotate forward and reverse at a constant speed via the frequency converter 12. The motor 3 then drives the lead screw 2 to switch back and forth between forward and reverse rotation. Since the motor 3 is threadedly connected to the slider 4, the forward and reverse rotation of the lead screw 2 will drive the slider 4 to move back and forth along the guide rail 5. The slider 4 will drive the guide wheel 7 to move back and forth through the bracket 6. The yarn will evenly contact different positions of the guide wheel 7, thereby achieving uniform wear of the yarn on the guide wheel 7, extending the equipment life and improving product quality.

[0058] Simultaneously, during the reciprocating motion of the guide wheel 7, distance sensors 9 and 10 are activated by the controller 11. Distance sensor 9 detects the distance between the fixing strip 8 and the guide wheel 7 in real time and sends it to the difference calculation module 13. Distance sensor 10 detects the distance between the guide wheel 7 and the inner right side wall of the base 1 in real time and sends it to the controller 11. After receiving the data, the difference calculation module 13 subtracts the distance detected by distance sensor 9 from the distance between the guide wheel 7 and the fixing strip 8 in the unused state. If a difference exists, the difference calculation module 13 sends the difference data to the wear analysis module 14. If no difference exists, ... If the system is operating normally, and a difference occurs, the wear analysis module 14 will analyze the severity of the wear based on the difference data received from the difference calculation module 13. If the difference is too large, it indicates that the wear is relatively severe; otherwise, the wear is relatively light. Based on the severity of the wear, the required frequency conversion value for motor 3 will be generated and sent to the controller 11. The controller 11 will simultaneously receive the distance between the guide wheel 7 and the inner right side wall of the base 1, as well as the required frequency conversion value for motor 3 at that position. The controller 11 will input the required frequency conversion values ​​for motor 3 at different position states into the drive data storage module 15 for storage.

[0059] In subsequent use, the controller 11 will control the inverter 12 in real time according to the frequency conversion values ​​of motor 3 stored in the drive data storage module 15 under different position states. When the severely worn part of the guide wheel 7 moves to the yarn position, the inverter 12 will increase the speed of motor 3 to reduce the contact time between the yarn and the guide wheel 7, thereby effectively reducing the wear on the severely worn part. When the normally worn part of the guide wheel 7 moves to the yarn position, the motor 3 will rotate normally at a uniform speed to maintain the initial speed of the guide wheel 7. By dynamically adjusting the stroke of the guide wheel 7 according to the wear condition of the guide wheel 7, the wear of the guide wheel 7 can be effectively reduced, thereby improving the service life of the equipment.

[0060] Among them: a second motor 16 is fixedly connected to the right side of the bracket 6, and the output shaft of the second motor 16 is fixedly connected to the guide wheel 7. A second frequency converter 17 is fixedly connected to the left side of the base 1. The input terminal of the second frequency converter 17 is connected to the controller 11, and the output terminal of the second frequency converter 17 is connected to the second motor 16.

[0061] In this invention, the frequency converter 17 is controlled by the controller 11 to adjust the speed of the motor 16, so that the speed of the guide wheel 7 is consistent with the speed of the wire conveying, which can effectively reduce the wear between the wire and the guide wheel 7, thereby improving the practicality of the device.

[0062] In practical use, if dust or lint on the surface of the guide wheel 7 affects the ranging effect, it may lead to misjudgment of the wear condition of the guide wheel 7 surface. To solve this problem, the following solution is provided:

[0063] Among them: a groove 18 is provided on the left side of the bracket 6, a square box 19 is slidably connected to the inner wall of the groove 18, a filter plate 20 is embedded on the front and back of the square box 19, an installation groove 21 is provided on the inner wall of the groove 18, a fan 22 is embedded on the inner wall of the two installation grooves 21, the input end of the fan 22 is connected to the controller 11, and an air intake groove 24 is provided on the inner top wall of the groove 18 at equal intervals.

[0064] In this invention, when the fan 22 is turned on, the fan 22 will draw the air out of the groove 18. The air around the guide wheel 7 will be drawn into the groove 18 from the air intake groove 24. During the air flow, the dust and lint on the surface of the guide wheel 7 will be carried away, thereby achieving the effect of cleaning the surface of the guide wheel 7 and avoiding the influence of dust or lint on the wear detection of the guide wheel 7.

[0065] Airflow can also dissipate heat from the guide wheel 7, effectively extending the lifespan of the device.

[0066] Among them, air outlet slots 23 are provided on both the front and back of the base 1, and both air outlet slots 23 are square.

[0067] In this invention, the air outlet slot 23 helps to discharge air to the front and back of the base 1, reducing the occurrence of hot air accumulating on the base 1.

[0068] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
