When the gap is cut, the feeding mechanism feeds the new optical fiber into the cutting cylinder 1, completing the automatic cutting of multiple optical fibers and improving the cutting efficiency.

[0024] In one embodiment of the present application, preferably, an annular groove 6 is provided on the fixed clamping seat 2, the bottom of the groove 6 is located on the center circumference of the optical fiber hole 3, a plurality of wedge-shaped telescopic cavities 7 are provided in the groove 6, the telescopic cavities 7 are cross-arranged with the optical fiber hole on the circumference of the bottom of the groove 6, a slidable wedge block 8 is provided in the telescopic cavity 7, an elastic tensioning belt 9 is provided in the groove 6, the outer side of the wedge block 8 is in contact with the tensioning belt 9, specifically, when the wedge block 8 is extended, the tensioning belt 9 is lifted, and the tensioning belt 9 no longer presses the optical fiber, at this time the feeding mechanism feeds the optical fiber into the cutting barrel 1, and when the wedge block 8 is retracted, the tensioning belt 9 clamps the optical fiber on the groove 6, so that the optical fiber is stabilized in the optical fiber hole 3, which is convenient for the blade 5 to cut.

[0025] In one embodiment of the present application, preferably, a cavity (not marked in the figure) is provided in the center of the fixed clamping seat 2, and a sliding rod 10 is fixedly connected in the cavity. A sliding sleeve 11 is sleeved on the sliding rod 10, and a slip ring 12 is slidably connected to the sleeve 11. A plurality of push rods 13 are hinged on the slip ring 12, and the other end of the push rod 13 is hinged to the inner side of the wedge block 8. Specifically, when the slip ring 12 moves, the push rod 13 pushes the wedge block 8 to extend out of the telescopic cavity 7 or pulls the push rod 13 to retract the wedge block 8 into the telescopic cavity 7.

[0026] In one embodiment of the present application, preferably, the feeding mechanism includes a movable clamping seat 14 which can slide on the slide rod 10. The movable clamping seat 14 is provided with the same clamping structure as the fixed clamping seat 2. The slip rings 12 of the fixed clamping seat 2 and the movable clamping seat 14 are both located between the fixed clamping seat 2 and the movable clamping seat 14, and are used to enable the movable clamping seat 14 to also loosen or press the optical fiber by moving the slip ring 12.

[0027] In one embodiment of the present application, preferably, a first fixing ring 15, a second fixing ring 16 and a third fixing ring 17 are fixedly connected to the sleeve 11. The first fixing ring 15 and the second fixing ring 16 are both located between the fixed clamping seat 2 and the movable clamping seat 14. The third fixing ring 17 and the second fixing ring 16 are respectively located on both sides of the slip ring 12 of the movable clamping seat 14. The first fixing ring 15 is used to push the slip ring 12 of the fixed clamping seat 2 to loosen the optical fiber by the fixed clamping seat 2. The second fixing ring 16 is used to push the slip ring 12 of the movable clamping seat 14 to loosen the optical fiber by the movable clamping seat 14. The third fixing ring 17 is used to push the slip ring 12 of the movable clamping seat 14 to clamp the optical fiber by the movable clamping seat 14. When the first fixing ring 15 moves away from the slip ring 12 along with the sleeve 11, the wedge block 8 retracts into the telescopic cavity 7 under the pressure of the tension belt 9 on the slip ring 12 of the fixed clamping seat 14 and pushes the slip ring 12 to move by itself, forming a self-clamping state.

[0028] In one embodiment of the present application, preferably, the fixed clamping seat 2 is fixedly connected with a bracket 18. One end of the bracket 18 is rotatably connected to the cutting cylinder 1. The other end of the bracket 18 is fixedly connected with a two-stage electric push rod 19. The first-stage push rod 20 of the electric push rod 19 is fixedly connected with the movable clamping seat 14. The second-stage push rod 21 of the electric push rod 19 is fixedly connected with the sleeve 11. The two-stage electric push rod 19 is used to make the movements of the sleeve 11 and the movable clamping seat 14 out of sync. Specifically, when feeding, the second-stage push rod 21 pushes the sleeve 11 forward. At this time, the third fixing ring 17 pushes the slip ring 12 to clamp the optical fiber by the movable clamping seat 14. The first fixing ring 15 pushes the slip ring 12 of the fixed clamping seat 2 to loosen the optical fiber by the fixed clamping seat 2. After the second-stage push rod 21 extends, the first-stage push rod 20 pushes the movable clamping seat 14 clamping the optical fiber to move towards the fixed clamping seat 2. After the optical fiber extends a target distance from the optical fiber hole 3 of the fixed clamping seat 2, the extension of the first-stage push rod 20 is stopped, and the second-stage push rod 21 is retracted. The first fixing ring 15 is disengaged from the slip ring 12 of the fixed clamping seat 2, and the tension belt 9 of the fixed clamping seat 2 clamps the optical fiber. At this time, the second fixing ring 16 pushes the slip ring 12 of the movable clamping seat 14 to loosen the tension belt 9 of the movable clamping seat 14 from the optical fiber. The first-stage push rod 20 starts to retract to drive the movable clamping seat 14 to reset, and the cutting is completed after the fixed clamping seat 2 clamps the optical fiber.

[0029] In an embodiment of the present application, preferably, a rotating motor 22 is fixedly connected to the bracket 18, and the drive shaft of the rotating motor 22 is fixedly connected to the cutting cylinder 1 for rotating the cutting cylinder 1 to complete the optical fiber cutting.

[0031] In summary, for the optical fiber rapid cutting device in the above embodiments of the present utility model, specifically, when starting the electric push rod 19, during feeding, the secondary push rod 21 pushes the sleeve 11 forward. At this time, the third fixing ring 17 pushes the sliding ring 12 to clamp the optical fiber by the moving clamping seat 14, and the first fixing ring 15 pushes the sliding ring 12 of the fixed clamping seat 2 to release the optical fiber by the fixed clamping seat 2. After the secondary push rod 21 extends, the primary push rod 20 pushes the moving clamping seat 14 to clamp the optical fiber and move towards the fixed clamping seat 2, so that the optical fiber extends into the cutting cylinder 1 from the optical fiber hole 3 of the fixed clamping seat 2. After extending the target distance, stop the extension of the primary push rod 20, retract the secondary push rod 21, the first fixing ring 15 disengages from the sliding ring 12 of the fixed clamping seat 2, and the tension belt 9 of the fixed clamping seat 2 clamps the optical fiber. Start the rotating motor 22 to drive the cutting cylinder 1 to drive the blade 5 to rotate to complete the cutting of the optical fiber. At the same time, the secondary push rod 21 continues to retract, and the second fixing ring 21 pushes the sliding ring 12 of the moving clamping seat 14 to release the tension belt 9 of the moving clamping seat 14 from the optical fiber. The primary push rod 20 starts to retract to drive the moving clamping seat 14 to reset. Repeat the above actions. When the cutting cylinder 1 rotates, the cut optical fiber heads fall into the fiber collecting box 24 from the fiber outlet 23. The automatic feeding of the optical fiber is completed through the cooperation of the feeding mechanism and the tensioning and releasing of the fixed clamping seat 2. The cutting cylinder 1 with the rotating multi-blades 4 is used to complete the cutting of multiple optical fibers at the same time, improving the cutting efficiency and meeting the needs of mass production.
