Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber cable equipment, and particularly relates to an automatic butterfly cable cutting, disc-changing and threading device and its usage method. Background Art

[0002] Currently, during the production of butterfly cables in enterprises, when the length of a reel of butterfly cable reaches the service length and production is completed, an operator needs to perform the operation of changing the disc. The main operations include cutting the butterfly cable, pulling the butterfly cable forward to the position of an empty disc tool, threading the butterfly cable from the inside of the disc tool to the outside, and then from the outside into the inner cylinder of the disc tool, and then clicking the start button to complete the operation of changing the butterfly cable disc.

[0003] All of the above operations need to be completed manually, and this operation has timeliness, that is, the operation must be performed immediately after the butterfly cable reaches the service length to complete the disc-cutting operation. If the disc-changing operation is not performed after the length is exceeded or the disc-changing operation time is too long, it will cause the scrapping of the next reel of butterfly cable products or the shutdown of the production line due to faults, resulting in losses.
