Description

Technical Field

[0001] This utility model relates to the field of optical fiber cutting technology, and more specifically, to an optical fiber cutting machine. Background Technology

[0002] Optical fiber is a type of fiber made of glass or plastic. It is a light transmission tool that uses the principle of total internal reflection to transmit light within these fibers. During the processing and use of optical fibers, they need to be cut, usually using a cutting machine. Existing optical fiber cutting machines have low efficiency in adjusting the position of the cutting mechanism for different cutting lengths, lacking a suitable and efficient adjustment mechanism. Furthermore, the clamping plate structure used for installation is prone to bending and damage after prolonged use, lacking a suitable quick replacement and maintenance mechanism. In addition, the cutter head is exposed for extended periods during loading and unloading before and after cutting, posing a danger to operators, and lacks a suitable installation protection mechanism.

The clamping mechanism clamps and holds the installed fiber.

[0029] When in the cutting state, after the optical fiber is installed, rotate the adjusting rod 27 in the opposite direction. The L-shaped protective plate 24 slides to a position that does not obstruct the cutting blade 22. The control device has its own control system, which starts the hydraulic cylinder 21. The hydraulic cylinder 21 extends and drives the bottom cutting blade 22 downward. The cutting blade 22 and the cutting groove 23 of the cutting seat 7 cooperate to cut the optical fiber.

[0030] When the clamping mechanism is under maintenance, after prolonged use, the entire pressure seat 15 is disassembled. The positioning ring 20 is rotated, and the positioning ring 20 and the positioning rod 18 are threaded together. After the positioning ring 20 is removed, the entire pressure seat 15 that drives the positioning rod 18 is disassembled. The new pressure seat 15 is installed corresponding to the pressure plate 14. The positioning rod 18 and the positioning hole 19 are positioned together. The positioning ring 20 and the positioning rod 18 are threaded together to achieve installation and locking, which facilitates replacement and maintenance.
