Description

Technical Field

[0001] The invention belongs to the technical field of mechanical component detection equipment, and in particular relates to a twisting shaft dynamic balance detection mechanism for a nylon rope twisting machine. Background Art

[0002] Nylon rope twisting machine is a kind of textile machinery equipment, and its core function is to twist multiple strands of fine nylon filaments into nylon rope through precise mechanical movement. This process not only involves merging individual nylon filaments, but also twisting these filaments to increase their strength and durability so that they can meet the needs of weaving and various operations. The twisting shaft, also known as the spindle, is used to support the yarn to ensure the stability of the yarn during the twisting process and prevent the yarn from breaking due to uneven tension or external forces. The stability of the spindle is crucial to ensure the quality of the nylon rope, which directly affects the uniformity and strength of the final product.

[0003] However, in the prior art, the twisting machine has some shortcomings in the process of twisting nylon filaments. Especially in the way of fixing the bobbin, many twisting machines adopt a relatively simple method, which causes the bobbin to easily shake slightly or heavily during the twisting process. If this shaking cannot be discovered and adjusted or repaired in time, it will not only affect the smoothness of the wire drawing process, but also increase the possibility of the nylon filament breaking during the twisting process. Sometimes the nylon filament will even get stuck on the wire rollers, bearings and other parts of the equipment due to this instability. This situation will not only reduce the quality of the nylon filament twisting, resulting in the performance of the finished nylon rope not meeting the standards, but may also cause equipment failure, thereby affecting the operation of the entire production line, and then causing the equipment to stop working, which will not only cause delays in production progress, but also increase maintenance costs, and have a negative impact on the company's production costs and profits.

[0004] Therefore, it is necessary to study a dynamic balance detection mechanism for a nylon rope twisting machine that can detect in real time whether the twisting shaft is shaking, so that when the twisting shaft shakes, it can stimulate and remind the staff to stop the equipment for adjustment or maintenance to avoid affecting the quality of the finished product.

[0038] See also Figures 1 to 10 As shown, a twisting shaft dynamic balance detection mechanism for a nylon rope twisting machine includes: a frame 1 for connecting to and supporting the twisting machine, a shaft end detection mechanism 2 for real-time detection of both ends of the twisting shaft, a shaft body detection module 3 for detecting the twisting shaft body, and a telescopic linkage rod 4 for linkage adjustment of the shaft body detection module 3 position.

[0039] The frame 1 is provided with a first slide rail 11, a first hinge shaft 12, and a second slide rail 13. The first slide rail 11 and the second slide rail 13 are arranged horizontally on the frame 1, and the first hinge shaft 12 is fixedly arranged on the frame 1. Specifically, the frame 1 is provided with connecting members 15 on both sides, and the connecting members 15 are connected to the twisting machine.

[0040] The shaft end detection mechanism 2 includes a first slider 21, a first adjustment rod 22, a second adjustment rod 23, a third adjustment rod 24, a second spring 25, a lever 26 and a first pressure sensor 27. The first slider 21 is slidably arranged on the first slide rail 11, and a second hinge shaft 211 is also arranged at the rear end of the first slider 21. The first adjustment rod 22 is fixedly arranged at the front end of the first slider 21, and the second adjustment rod 23 is slidably arranged on the first adjustment rod 22. Specifically, a first positioning hole 221 is arranged on the first adjustment rod 22, and correspondingly, a second positioning hole 231 is arranged on the second adjustment rod 23. The second adjustment rod 23 can be fixed by passing a bolt through the first positioning hole 221 and the second positioning hole 231. It can be understood that during installation, by pulling out at least part of the second adjustment rod 23 from the first adjustment rod 22, and aligning the corresponding first positioning hole 221 and the second positioning hole 231, the second adjustment rod 23 can be fixed by passing a bolt through the aligned first positioning hole 221 and the second positioning hole 231.

[0041] Specifically, the second adjusting rod 23 is also provided with a first rotating wheel 232, a guide hole 233 and a first positioning pin 234. The first rotating wheel 232 is rotatably arranged at the front end of the second adjusting rod 23, and the first positioning pin 234 is arranged above the guide hole 233. It can be understood that the first rotating wheel 232 is squeezed together with the twisting shaft, and the first rotating wheel 232 can rotate together with the twisting shaft.

[0042] The third adjusting rod 24 is slidably arranged on the second adjusting rod 23. Specifically, the third adjusting rod 24 is provided with a guide rod 241, a first spring 242 and a second rotating wheel 243. The guide rod 241 is fixedly arranged at the rear end of the third adjusting rod 24. The guide rod 241 is slidably arranged in the guide hole 233. The guide rod 241 is pressed and matched with the first positioning pin 234. The third adjusting rod 24 is connected to the second adjusting rod 23 through the first spring 242. The second rotating wheel 243 is rotatably arranged On the third adjusting rod 24, it can be understood that, during installation, the first positioning pin 234 is loosened, and the third adjusting rod 24 is pulled so that at least part of the guide rod 241 extends from the guide hole 233, so that the second rotating wheel 243 cooperates with the other side of the twisting shaft, and the first spring 242 releases the elastic force and contracts to ensure that the second rotating wheel 243 always cooperates with the twisting shaft, and then the first positioning pin 234 is locked. The third adjusting rod 24 can ensure that the first rotating wheel 232 on the second adjusting rod 23 always cooperates with the twisting shaft when the twisting machine is working.

[0043] The first slider 21 is connected to the frame 1 through the second spring 25, the middle part of the lever 26 is hinged on the first hinge shaft 12, the upper end of the lever 26 is hinged to the second hinge shaft 211, the first pressure sensor 27 is fixedly arranged on the frame 1, and the lower end of the lever 26 is squeezed and matched with the first pressure sensor 27. It can be understood that when the two ends of the twisting shaft shake, the twisting shaft pushes the first slider 21 to slide backward along the first slide rail 11 through the second adjusting rod 23 and the first adjusting rod 22, and the first slider 21 drives the lever 26 to squeeze the first pressure sensor 27 through the second hinge shaft 211. The first pressure sensor 27 feeds back the pressure value in real time. When it exceeds the threshold, it will prompt the staff to make adjustments or repairs.

[0044] The shaft body detection module 3 includes a bracket 31 , a second slider 32 , a third spring 33 and a second pressure sensor 34 . The bracket 31 is slidably set on the second slide rail 13, and the bracket 31 is provided with a third slide rail 312. The second slider 32 is slidably set on the third slide rail 312. The second slider 32 is provided with a third rotating wheel 321 and a contact 322. The front end of the second slider 32 is rotatably provided with the third rotating wheel 321, and the rear end of the second slider 32 is connected to the frame 1 through a third spring 33. The second pressure sensor 34 is fixedly set on the bracket 31, and the contact 322 is squeezed and matched with the second pressure sensor 34. It can be understood that when the twisting machine is working, the roller wrapped with nylon thread is sleeved on the twisting shaft, and the third rotating wheel 321 cooperates with the nylon thread on the roller. When the twisting shaft and the roller shake, the third rotating wheel 321 pushes the second slider 32 to slide backward along the third slide rail 312, and then squeezes the second pressure sensor 34 through the contact 322. The second pressure sensor 34 monitors the pressure value in real time, and when it exceeds the threshold, it will prompt the staff to make adjustments or repairs.

[0045] The frame 1 is provided with a first slide groove 14. Specifically, the bracket 31 is provided with a second positioning pin 311. The second positioning pin 311 cooperates with the first slide groove 14. It can be understood that the bracket 31 can be locked and unlocked by the second positioning pin 311. When the second positioning pin 311 is released to unlock the bracket 31, the bracket 31 can slide along the second slide rail 13. Correspondingly, a linkage shaft 313 is provided on the lower end surface of the bracket 31. The linkage shaft 313 is hinged on the telescopic linkage rod 4. The telescopic linkage rod 4 slides with the frame 1 and the bracket 31. It can be understood that since the overall side surface of the nylon wire on the drum may be a plane or an inclined surface, when installing, after releasing the second positioning pin 311 to unlock the bracket 31, the brackets 31 of the shaft body detection modules 3 on both sides are pushed to make the third rotating wheel 321 contact with the nylon wire. At this time, the telescopic linkage rod 4 will drive the third rotating wheel 321 of the middle shaft body detection module 3 to synchronously contact with the nylon wire, so that the installation can be completed quickly and conveniently, and the application range of the equipment can be improved.

[0046] Working principle of the present invention:

[0047] Installation and adjustment: The mechanism is installed on the twisting machine through the connecting piece 15; by pulling out at least part of the second adjusting rod 23 from the first adjusting rod 22, the first rotating wheel 232 is pressed and matched with one side of the twisting shaft, and the corresponding first positioning hole 221 and the second positioning hole 231 are aligned, and the second adjusting rod 23 can be fixed by passing the bolt through the aligned first positioning hole 221 and the second positioning hole 231; loosen the first positioning pin 234, pull the third adjusting rod 24, so that at least part of the guide rod 241 extends out of the guide hole 233, so that the second rotating wheel 243 is aligned with the twisting shaft. The other side of the first spring 242 releases its elastic force and contracts to ensure that the second rotating wheel 243 is always coordinated with the twisting shaft. Then, the first positioning pin 234 is locked. The third adjusting rod 24 can ensure that the first rotating wheel 232 on the second adjusting rod 23 is always coordinated with the twisting shaft when the twisting machine is working. After loosening the second positioning pin 311 to unlock the bracket 31, the brackets 31 of the shaft body detection modules 3 on both sides are pushed to make the third rotating wheel 321 contact with the nylon thread. At this time, the telescopic linkage rod 4 will drive the third rotating wheel 321 of the middle shaft body detection module 3 to synchronously contact with the nylon thread, so that the installation can be completed quickly and conveniently.

[0048] Working: When the twisting machine is working, when the twisting shaft shakes, the twisting shaft pushes the first slider 21 to slide backward along the first slide rail 11 through the second adjusting rod 23 and the first adjusting rod 22, and the first slider 21 drives the lever 26 to squeeze the first pressure sensor 27 through the second hinge shaft 211. The first pressure sensor 27 feeds back the pressure value in real time, and when it exceeds the threshold, it will remind the staff; the roller wrapped with nylon thread is sleeved on the twisting shaft, and the third rotating wheel 321 cooperates with the nylon thread on the roller. When the twisting shaft and the roller shake, the third rotating wheel 321 pushes the second slider 32 to slide backward along the third slide rail 312, and then squeezes the second pressure sensor 34 through the contact 322. The second pressure sensor 34 monitors the pressure value in real time, and when it exceeds the threshold, it will remind the staff. When the twisting shaft shakes, it can be discovered in time and the staff can be reminded to make adjustments or repairs to prevent this situation from reducing the quality of the nylon thread twisting, resulting in the performance of the finished nylon rope not meeting the standards, and at the same time prevent equipment failure, thereby affecting the operation of the entire production line.
