Automatic cable twisting and winding production line and method thereof for precisely controlling pitch

Abstract

The invention relates to the technical field of wire winding and discloses an automatic cable twisting and winding production line which comprises a driving paying out machine, wherein an untwisting paying out machine, a cable collecting device, a material coating device, a belt storage device and a winding machine are sequentially arranged at the output end of the driving paying out machine; the driving paying out machine and the untwisting paying out machine unwind cable, the cable penetrates through the cable collecting device to form a cable harness, the winding machine rotates to twist, wind and form the cable harness, the twisted and winded cable harness penetrate through the material coating device, the material coating device coats the twisted and winded cable harness, and the finished cable enters the winding machine to be taken up; and the untwisting paying out machine unwinds the cable and rotates a paying out shaft for storing the cable to release twisting and winding stress transmitted by the winding machine through the cable. The automatic cable twisting and winding production line prevents the finished cable from the bump phenomenon due to stress accumulation, the cable is high in quality, and the advantage of manual work saving; and an accurate pitch control method, provided by the invention, can ensure that output of the twisting and winding stress is more stable and can manufacture the cable with high precision requirement for pitch.

AI Technical Summary

Benefits of technology

This patented technology allows for efficient creation of helically wrapped electrical conductors without excessive strain on them during their process or use. It achieves this by automatically unwrapping each strand after being fed onto one side (the primary) of two drums - either before or afterwards. A concentratory device separats these bundles together and forms packages containing the final product. These packages then go through various steps like wrapping around insulators, forming wraps over protectively coated metal tubes, and finally covering them with plastic covers. After finishing all three processes, they exit the system where they were stored until needed again. Overall, this technology simplifies the way electric cabling was made and improves its overall performance.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the accuracy and consistency during manufacturing of high voltage electrical conductors (HVAC) which require precise placement of insulation material on both ends of these strands. Experimental results showed that increasing tension force caused by twist strain could cause damage to the HVAC's structure while reducing its performance. To address this issue, there was developed a device called a spooler that controls the amount of twist applied to the electricity lines without causing any issues like bulging out the outer layer of insulating materials around them.
