The first photoelectric sensor and the second photoelectric sensor are signal-connected to the driving device.

[0005] Based on the above technical solution, the present invention can be further improved as follows.

[0006] Furthermore, the wire guiding device includes a wire guiding plate and a wire pressing roller. The wire pressing roller is rotatably mounted on one end of the wire guiding plate.

[0018] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0019] This utility model provides a plastic optical fiber cutting system that can solve the problems of low automation and wasted manpower in related technologies.

[0020] See Figure 1 and Figure 2 As shown, a plastic optical fiber cutting system provided by this utility model embodiment includes a wire feeding device 1, a wire guiding device 2, and a cutting device 3. The wire feeding device 1 includes a mounting base 11, a wire roller 12, and a driving device 13. The wire roller 12 and the driving device 13 are mounted on the mounting base 11, and the driving device 13 is connected to the wire roller 12. A first photoelectric sensor 14 and a second photoelectric sensor 15 are mounted on the mounting base 11. The first photoelectric sensor 14 is located below the wire roller 12, and the second photoelectric sensor 15 is located at the lower end of the mounting base 11. The first photoelectric sensor 14 and the second photoelectric sensor 15 are signal-connected to the driving device 13. By setting photoelectric sensors on the wire feeding device, after the sensor below the wire roller senses the optical fiber, the wire roller automatically accelerates to pull the optical fiber for cutting. When a roll of optical fiber reaches its last turn, the end falls to the bottom of the mounting base, and the lower sensor detects this, causing the wire roller to automatically stop. This realizes the automation of the wire feeding device's switching, saves manpower, and improves efficiency.

[0021] See Figure 3 As shown, in some embodiments, the wire guiding device 2 includes a wire guiding plate 21 and a wire pressing roller 22. The wire pressing roller 22 is rotatably mounted on one end of the wire guiding plate 21. The upper end of the wire guiding plate 21 is provided with a plurality of U-shaped openings 23. The wire pressing roller 22 is used to press the U-shaped openings 23. The wire guiding groove adopts a U-shaped opening to facilitate wire passing. The wire pressing roller 22 is used to press the U-shaped openings 23 to prevent the wire from jumping out.

[0022] See Figure 1 As shown, in some embodiments, the wire guiding device 2 is provided with a hot water tank 4 on the side near the cutting device 3, which can soften the hard outer material of the optical fiber and make it easier to cut.

[0023] See Figure 4 As shown, in some embodiments, the cutting device 3 includes a feeding roller 31 and a cutting machine 32. A plurality of the feeding rollers 31 are arranged on the inlet and outlet sides of the cutting machine 32, and the feeding and discharging of the cutting are driven forward by the feeding rollers 31.

[0024] See Figure 4As shown, in some embodiments, a lower pressure roller 33 is provided above the feeding rollers 31 on both sides of the cutting machine 32. The lower pressure roller 33 is mounted on a moving device and can move downward. By cooperating with the feeding rollers 31, the lower pressure roller 33 clamps the optical fiber and rolls it, realizing the composite correction of axial torsion and radial bending of the optical fiber. This effectively eliminates the influence of material springback on the cutting accuracy, while firmly clamping the optical fiber to ensure stability during the processing and guarantee the quality of the cut surface, thereby ensuring stable and reliable processing quality.

[0025] See Figure 4 As shown, in some embodiments, the moving device includes a linear guide rail 34, on which a slider 35 is mounted. The two ends of the lower pressure roller 33 are connected to the slider 35 through a linkage mechanism 36. The movement of the slider 35 drives the lower pressure roller 33 to rise or fall, enabling the lower pressure roller 33 to quickly release the clamp on the optical fiber, greatly improving the transfer efficiency of the optical fiber. The structure is simple and improves the ease of operation.

[0026] See Figure 4 As shown, in some embodiments, there are two sliders 35, and the linkage mechanism 36 is square. The left and right ends of the linkage mechanism 36 are respectively connected to the two sliders 35. The two sliders 35 can move simultaneously in opposite directions, thereby driving the linkage mechanism 36 to deform and causing the lower pressure roller 33 to rise or fall.

[0027] See Figure 4 As shown, in some embodiments, the upper end of the linkage mechanism 36 is connected to the lower pressure roller 33, and the lower end is installed in the guide groove 37, which guides the movement of the lower end of the linkage mechanism 36, thereby ensuring the stability of the movement of the lower pressure roller 33.

[0028] See Figure 4 As shown, in some embodiments, an encoder 38 is installed at one end of the lower pressure roller 33 at the outlet of the cutting machine 32. The encoder 38 can measure the rotation angle of the lower pressure roller 33, thereby calculating the number of rotations of the lower pressure roller 33. When the cable passes under the lower pressure roller 33 at the outlet of the cutting machine 32, the lower pressure roller 33 descends to press the cable and rotates to continue conveying the cable. When the encoder 38 detects that the number of rotations of the lower pressure roller 33 has reached a set value, it indicates that the required fiber length (circumference of the lower pressure roller * number of rotations + distance from the lower pressure roller to the cutting machine blade) has been reached. After driving the cutting machine 32 to cut, the required length can be obtained.

[0029] See Figure 4As shown, in some embodiments, the encoder 38 is connected to the cutting machine 32. A photoelectric sensor is provided on the frame near the lower pressure roller 33. The photoelectric sensor, encoder 38, and cutting machine 32 are all connected to the control device. When the photoelectric sensor detects the optical fiber, the control device drives the lower pressure roller 33 to descend. The encoder 38 detects the number of rotations of the lower pressure roller 33. The control device drives the cutting machine 32 to cut, realizing automated length counting and cutting, significantly improving length accuracy and cutting efficiency, optimizing the overall process, reducing manual intervention, and lowering production costs.
