Description

Technical Field

[0001] The present invention relates to a processing technology for communication cables, and particularly to a processing technology for communication cables. Background Art

[0002] A communication cable is a communication line composed of multiple mutually insulated wires or conductors forming a cable core, with a sealed sheath on the outside. Some also have an outer protective layer outside the sheath. There are various laying methods such as overhead, direct burial, pipeline, and underwater. It is divided into symmetrical, coaxial, and integrated cables according to the structure; and into field and permanent cables (underground and submarine cables) according to the function. The communication cable has a relatively wide transmission frequency band, a large communication capacity, and is less affected by external interference, but it is not easy to repair. It can transmit telephone, telegraph, data, images, etc.

[0003] In the production process, various different cables are used. Different types of cables require different pitches, and finally the thickness of the coil formed by the coiling machine is also different. When two cables are twisted together, the spiral distance of a small section between them is also called the pitch. During the production process, cables with different pitches are processed. During the process of adjusting the pitch of the cable by the current twisting machine, four adjusting gears need to be replaced, and different adjusting gears are used to change the processing speed, so as to achieve the effect of changing the cable pitch.

[0004] However, currently, during the replacement process of the four gears of the twisting machine, manual replacement is carried out. Nuts are screwed onto the threaded rods to clamp the gears. Manual replacement is time-consuming and laborious, and during the replacement process, the gears are prone to falling off, causing gear damage, resulting in a decrease in accuracy. Moreover, the coiling machine needs different thicknesses to form a coil. Since the length of the drum cannot be changed, the drum needs to be replaced at this time, but the drum replacement is troublesome. Summary of the Invention
