Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn tension detection technology, specifically a yarn tension detection mechanism. Background Technology
[0002] The ring spinning machine has a history of over 160 years, dating back to the initial prototype invented by Chap in 1828. However, its development has long been limited by the constraints imposed by the ring and traveler. The traveler, used for over a century, presents increasingly more problems in this modern, high-speed, and digital age.
[0003] During spinning, the tension of the yarn is entirely controlled by the friction of the traveler. Therefore, to change the tension of the yarn during spinning, the machine must be stopped and the traveler manually replaced. In this mode, it is unnecessary to dynamically test the tension of the yarn during spinning. The traditional method is to manually touch the yarn and judge the tension based on the worker's experience. Since the tension cannot be adjusted in real time during spinning, the machine must be stopped and the traveler replaced. Therefore, a yarn tension detection mechanism is proposed.

Example
[0029] Please see Figure 1-6This utility model provides a technical solution: a yarn tension detection mechanism, including a mounting plate 1, a motor 2 mounted on one side of the top of the mounting plate 1, a yarn tube 3 mounted on the output shaft end of the motor 2, a yarn body 4 wound around the outside of the yarn tube 3, the drawn yarn body 4 output from the front roller nip, is wound into the electromagnetic collar, the yarn body 4 passes through one side of the yarn guide hook 5, and is wound around the outside of the yarn tube 3, the switch is pressed to control the output shaft of the motor 2 to drive the yarn tube 3 to rotate; a support plate 9 is fixed on one side of the top of the mounting plate 1, a connecting plate 8 is fixed on one side of the support plate 9, a tension sensor 6 is provided on one side of the connecting plate 8, and a yarn guide hook 5 is mounted on one end of the tension sensor 6. The support plate 9 has a display screen 10 and a controller 11 installed on one side of its back. When the yarn body 4 slides on the side of the yarn guide hook 5, the yarn guide hook 5 generates a lateral pressure. The lateral pressure is applied to the side of the tension sensor 6, and the resistance strain gauge of the tension sensor 6 generates a corresponding voltage signal. The strain gauge signal is amplified by the zero-drift amplifier circuit of the tension transmitter plate and then transmitted to the controller 11 for processing. An electromagnetic cable (not shown in the figure) is installed on the side of the motor 2. The electromagnetic cable is located on the lower side of the yarn tube 3. The tension is sampled every 30 degrees of the electromagnetic cable, and the average value is calculated for each 360 degrees to obtain the tension of each twist of the yarn body 4.
[0030] The model number of tension sensor 6 is HY-639M;
[0031] The model of controller 11 is STM32G431RBT6.
[0032] The signal output terminal of the tension sensor 6 is electrically connected to the input terminal of the display screen 10 and the controller 11. The output terminal of the controller 11 is electrically connected to the input terminal of the motor 2. The required spinning tension of the yarn body 4 is set on the display screen 10. The outer side of the yarn body 4 is slidably connected to one side of the yarn guide hook 5. The yarn guide hook 5 is located on the top side of the yarn tube 3.
[0033] One side of the connecting plate 8 is provided with a connecting assembly 7 for assembling and disassembling the tension sensor 6;
[0034] The connecting assembly 7 includes a connecting frame 71 and a connecting rod 79. A locking groove 710 is provided on one side of the connecting rod 79. A sliding groove 77 and a limiting groove 711 are provided inside the connecting frame 71. A sliding plate 74 is slidably connected to the inner side of the sliding groove 77. A locking rod 78 is fixed to one side of the bottom of the sliding plate 74. When the pull rod 72 is pulled upward, the pull rod 72 drives the sliding plate 74 and the locking rod 78 to move upward, so that the locking rod 78 leaves the inner side of the locking groove 710. At this time, the tension sensor 6 can be removed.
[0035] A pull rod 72 is fixed to one side of the top of the slide plate 74. A spring 76 is sleeved on the outside of the pull rod 72. A cover plate 73 is threaded to one side of the top of the connecting frame 71. The connecting rod 79 of the tension sensor 6 is inserted into the inner side of the limiting groove 711. Then, the pull rod 72 is pulled upward to compress the spring 76. The two ends of the spring 76 are respectively connected to the cover plate 73 and one side of the slide plate 74. One side of the connecting frame 71 is fixed to one side of the connecting plate 8. One side of the connecting rod 79 is fixed to one side of the tension sensor 6. A vent hole 75 is opened on one side of the slide plate 74. When the connecting rod 79 is inserted to the bottom, the pulling force of the pull rod 72 is released. Under the elastic force of the spring 76, the locking rod 78 is pushed into the inner side of the locking groove 710. At this time, the installation of the tension sensor 6 is completed.
[0036] Working principle: When spinning is required, the yarn body 4 is passed through one side of the yarn guide hook 5 and wrapped around the outside of the yarn tube 3. Pressing the switch controls the output shaft of the motor 2 to drive the yarn tube 3 to rotate, wrapping the yarn body 4 around the outside of the yarn tube 3. When the yarn body 4 slides on one side of the yarn guide hook 5, the yarn guide hook 5 generates a lateral pressure. The lateral pressure is applied to one side of the tension sensor 6, and the resistance strain gauge of the tension sensor 6 generates a corresponding voltage signal. The strain gauge signal is amplified by the zero-drift amplifier circuit of the tension transmitter board and transmitted to the controller 11 for processing. At this time, the display screen 10 displays the tension value of the yarn body 4. According to the user's yarn tension setting value, the controller 11 controls the magnitude and direction of the electromagnetic force of the motor 2, thereby achieving stable yarn tension control during the spinning process. The motor 2 is driven by a three-phase split bridge. The controller 11 changes the magnitude and direction of the electromagnetic force of the motor 2 by changing the voltage output duty cycle and direction of the three-phase split bridge, thereby achieving real-time control of the tension of the yarn body 4.
[0037] When the tension sensor 6 needs to be disassembled for maintenance, simply pull the lever 72 upwards. At this time, the lever 72 will drive the slide plate 74 and the locking lever 78 to move upwards, so that the locking lever 78 leaves the inside of the locking groove 710. Then, pull the tension sensor 6 to one side, so that the tension sensor 6 will drive the connecting rod 79 to move out from the inside of the limiting groove 711. At this time, the tension sensor 6 can be removed.
[0038] Insert the connecting rod 79 on one side of the maintained tension sensor 6 into the inner side of the limiting groove 711, and then pull the pull rod 72 upward to compress the spring 76. When the connecting rod 79 is fully inserted, release the pulling force of the pull rod 72. Under the elastic force of the spring 76, push the locking rod 78 into the inner side of the locking groove 710. At this time, the installation of the tension sensor 6 is completed.
[0039] In summary, by using tension sensor 6 to detect the lateral pressure generated by the yarn body 4 on one side of the yarn guide hook 5 in real time and converting it into a voltage signal and transmitting it to controller 11, the tension value of the yarn body 4 can be obtained in real time and dynamically adjusted according to the user's setting value to ensure the stability of the tension of the yarn body 4 during the spinning process.
[0040] Users can easily unlock the tension sensor 6 by simply pulling the lever 72 upwards and remove it from the equipment for maintenance. The installation process is also simple: insert the connecting rod 79 into the limiting slot 711, pull the lever 72 again to release it, and the spring 76 will automatically push the locking rod 78 to lock it. This greatly simplifies the operation process, reduces the skill requirements for operators, and makes disassembly and installation quick and easy. Users can replace or maintain the tension sensor 6 more quickly, thereby shortening equipment downtime and improving the overall maintenance efficiency of the production line.
