Description

Technical Field

[0001] This invention relates to the field of optical fiber and cable processing technology, specifically to a cutting device for optical fiber and cable processing. Background Technology

[0002] Optical fiber, short for optical waveguide fiber, is a type of fiber made of glass or plastic used as a means of light transmission. The transmission principle of optical fiber is "total internal reflection of light." Typically, a transmitting device at one end of the fiber uses a light-emitting diode or a laser beam to transmit light pulses into the fiber, while a receiving device at the other end uses a photosensitive element to detect the pulses. Because the transmission loss of light in an optical fiber is much lower than the transmission loss of electricity in a wire, optical fiber is often used for long-distance information transmission. Fine optical fibers are encapsulated in a plastic sheath to form optical cables. The outer protective and insulating layers of the fiber prevent damage from the surrounding environment.

[0003] However, during the processing of optical fibers, because the outer surface of the optical fiber is encapsulated with an insulating protective layer, it is often necessary to separate the surface insulating layer when cutting the optical cable to expose the internal optical fiber. In practice, operators often need to use different tools to cut and separate the optical fiber insulation layer, and different specifications of cutting tools need to be prepared according to the thickness of the optical cable, which is quite inconvenient.

Detailed Implementation

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figure 1 , Figure 2 , Figure 4 As shown, the optical fiber and cable cutting device of the present invention includes an installation cylinder 1, a positioning structure 2 on the inner side of the installation cylinder 1, a cutting structure 3 in the middle of the positioning structure 2, a cutting structure 5 at the end of the installation cylinder 1, a release structure 6 connected between the cutting structure 5 and the installation cylinder 1, a fixing structure 7 on the positioning structure 2, and a control structure 4 connected between the installation cylinder 1 and the fixing structure 7.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the positioning structure 2 includes a first positioning plate 204 and a second positioning plate 206. Two first positioning plates 204 and two second positioning plates 206 are oppositely provided in the middle of the mounting cylinder 1. The first positioning plate 204 and the second positioning plate 206 are slidably connected to the inner side of the mounting cylinder 1 in a "cross" shape. Two first positioning wheels 205 are rotatably connected to the side surface of the first positioning plate 204, and a second positioning wheel 207 is rotatably connected to the side surface of the second positioning plate 206. A first spring 208 is fixedly connected between the first positioning plate 204 and the mounting cylinder 1, and a second spring 209 is fixedly connected between the second positioning plate 206 and the mounting cylinder 1. The side surfaces of the first positioning plate 204 and the second positioning plate 206 are provided with inclined surface structures. An adjusting sleeve 201 is rotatably connected to the end of the mounting cylinder 1, and a threaded sliding sleeve 202 is slidably connected to the inner side of the mounting cylinder 1. The adjusting sleeve 201 is threadedly connected to the threaded sliding sleeve 202. Four inclined surface pushing blocks 203 are fixedly connected to the end of the adjusting sleeve 201 in a circular shape. The inclined surface pushing block 203 has a "U" - shaped structure, and the end of the inclined surface pushing block 203 is provided with an inclined surface structure. The first positioning plate 204 and the second positioning plate 206 are slidably connected to the corresponding inclined surface pushing blocks 203 through the inclined side surfaces;

[0037] When the optical cable to be cut passes through the mounting cylinder 1, through the sliding of the first positioning plate 204 and the second positioning plate 206 inside the mounting cylinder 1, the optical cable can be positioned at the central axis position of the mounting cylinder 1 through the clamping action of the first positioning wheels 205 and the second positioning wheels 207. In order to ensure that the first positioning plate 204 and the second positioning plate 206 move synchronously, after the user passes the optical cable to be cut through the mounting cylinder 1, the adjusting sleeve 201 located at the end of the mounting cylinder 1 can be rotated. When the adjusting sleeve 201 rotates, it will drive the threaded sliding sleeve 202 to move towards the inner side of the mounting cylinder 1. At this time, the multiple inclined surface pushing blocks 203 arranged at the end of the threaded sliding sleeve 202 will push the first positioning plate 204 and the second positioning plate 206 through the inclined surfaces, thereby driving the first positioning plate 204 and the second positioning plate 206 to clamp the optical cable in the middle through the first positioning wheels 205 and the second positioning wheels 207. At the same time, due to the setting of the first positioning wheels 205 and the second positioning wheels 207, the optical cable can be kept in the middle of the mounting cylinder 1 and move, which is convenient for the fixation of optical cables of different specifications and the cutting of the insulating skin.

[0038] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 6As shown, the cutting structure 3 includes a mounting slider 306. The mounting slider 306 is slidably connected to the middle of the first positioning plate 204. A first cutting blade 305 is fixedly connected to the end of the mounting slider 306. The other end of the mounting slider 306 is slidably connected to the inner wall of the mounting cylinder 1. A first screw 304 is rotatably connected to the side of the mounting cylinder 1. The first screw 304 is threadedly connected to the mounting slider 306. The end of the first cutting blade 305 has a triangular structure. A drive gear 303 is fixedly connected to the end of the first screw 304 away from the mounting slider 306. A transmission gear ring 302 is rotatably connected to the outer side of the mounting cylinder 1. The side of the transmission gear ring 302 meshes with the drive gear 303. An adjusting gear 301 meshes with the other side of the transmission gear ring 302. The adjusting gear 301 is rotatably connected to the mounting cylinder 1.

[0039] After the optical cable is cut, in order to facilitate the removal of the insulation at the end of the optical cable, after the optical cable is fixed by the positioning structure 2, the user can rotate the adjusting gear 301 located on the side of the mounting cylinder 1. The adjusting gear 301 will drive the transmission gear ring 302 to rotate, and the transmission gear ring 302 will further drive the two drive gears 303 on both sides and the first screw 304 to rotate, thereby adjusting the position of the mounting slider 306 with less effort. The mounting slider 306 is slidably connected to the first positioning plate 204. By adjusting the position of the mounting slider 306, the distance between the first cutting blades 305 on both sides can be adjusted. The end of the first cutting blade 305 has a triangular structure. At this time, the user slowly pulls out the optical cable, and the first cutting blade 305 can cut the insulation on the surface of the optical cable, which facilitates the subsequent cleaning of the internal optical fiber.

[0040] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 11 As shown, the cutting structure 5 includes a rotating sleeve 501. The end of the mounting cylinder 1 is rotatably connected to the rotating sleeve 501. The two sides of the rotating sleeve 501 are respectively slidably connected to a first lifting block 506 and a second lifting block 507. A second cutting blade 503 is fixedly connected to the side of both the first lifting block 506 and the second lifting block 507. A reversing gear ring 504 is rotatably connected to the middle of the rotating sleeve 501. A side rack 505 is fixedly connected to the side of the first lifting block 506 and the second lifting block 507. The side rack 505 is slidably connected to the inner side of the rotating sleeve 501. The two side racks 505 are respectively meshed with the two sides of the reversing gear ring 504. A second screw 502 is rotatably connected to the side of the rotating sleeve 501. The second screw 502 is threadedly connected to the first lifting block 506.

[0041] When it is necessary to cut the optical cable, the user can directly rotate the second screw 502 on the side of the rotating sleeve 501. The second screw 502 will drive the first lifting block 506 to slide. At the same time, the side rack 505 on the side of the first lifting block 506 will drive the second lifting block 507 to slide in the opposite direction to the first lifting block 506 through the reversing gear ring 504 in the middle and the side rack 505 on the other side. Meanwhile, the sides of the first lifting block 506 and the second lifting block 507 are fixed with second cutting blades 503. The user can adjust the distance between the two second cutting blades 503. The distance between the first cutting blade 305 and the second cutting blade 503 can be adjusted to directly cut the optical cable. In addition, in order to improve the cutting effect on the optical fiber insulation, the user can also adjust the distance between the second cutting blades 503 before cutting with the first cutting blade 305, so that the second cutting blade 503 can cut the insulation. At this time, with the fixing effect of the positioning structure 2, the user can directly rotate the rotating sleeve 501 to achieve a circumferential cut on the outer insulation of the optical cable. Combined with the subsequent cutting effect of the first cutting blade 305, the cut of the insulation is clean, and the cutting effect on the optical fiber is improved.

[0042] Specifically, such as Figure 1 , Figure 5 , Figure 11 As shown, the release structure 6 includes a positioning slide rod 603. The positioning slide rod 603 is slidably connected to the inner side of the rotating sleeve 501. Both ends of the positioning slide rod 603 are hemispherical structures. The end of the mounting cylinder 1 is provided with multiple positioning grooves 604. The multiple positioning grooves 604 are arranged in a ring. One end of the positioning slide rod 603 abuts against the mounting cylinder 1 through the positioning groove 604. The side of the rotating sleeve 501 is slidably connected with a release block 601. A third spring 602 is fixedly connected between the release block 601 and the rotating sleeve 501. The side of the release block 601 abuts against the end of the positioning slide rod 603. The side of the release block 601 is provided with an abutment groove 605.

[0043] To facilitate control of the rotation of the rotating sleeve 501, a positioning slide rod 603 is provided on the inner side of the rotating sleeve 501. When the rotating sleeve 501 does not need to be rotated, one end of the positioning slide rod 603 abuts against the mounting cylinder 1 through the positioning groove 604, while the other end of the positioning slide rod 603 directly abuts against the side of the release block 601. Since the positioning slide rod 603 cannot slide, the rotating sleeve 501 cannot rotate at this time, which facilitates the user to perform preliminary fixing or cutting of the optical cable in the mounting cylinder 1. When it is necessary to rotate the rotating sleeve 501 to perform circumferential cutting of the outer insulation of the optical cable, the user can press the release blocks 601 located on both sides of the rotating sleeve 501. At this time, the abutment groove 605 on the side of the release block 601 is aligned with the positioning slide rod 603, so that the positioning slide rod 603 can slide towards the abutment groove 605, thereby releasing the locking state of the rotating sleeve 501 and facilitating the cutting of the optical cable.

[0044] Specifically, such as Figure 4 , Figure 7 As shown, the fixed structure 7 includes a side toothed ring 701. A side toothed ring 701 is fixedly connected to each end of the second positioning wheel 207. A brake toothed plate 703 is slidably connected to the side of the second positioning plate 206. The side of the brake toothed plate 703 has a toothed structure. A fourth spring 704 is fixedly connected between the brake toothed plate 703 and the second positioning plate 206. A push rod 702 is rotatably connected to the middle of the second positioning plate 206. The push rod 702 has a cross-shaped structure. Two protrusions 705 are symmetrically provided on the side of the brake toothed plate 703. The two sides of the push rod 702 are slidably connected to the protrusions 705.

[0045] When cutting the optical cable, the optical cable can also be fixed to ensure the stability of the cutting. The second positioning wheel 207 on the second positioning plate 206 is provided with a side toothed ring 701 on each side. When the push rod 702 on the second positioning plate 206 rotates, the rod-shaped parts on both sides of the push rod 702 will rotate to the top of the protrusion 705, thereby pushing the brake toothed plate 703 to the bottom, so that the toothed structure on both sides of the brake toothed plate 703 meshes with the side toothed ring 701, preventing the second positioning wheel 207 from rotating. At this time, combined with the clamping effect of the first positioning wheel 205 on the optical cable, the current position of the optical cable can be fixed to ensure the fixation of the optical cable when the second cutting blade 503 performs circumferential cutting or cuts the optical cable.

[0046] Specifically, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 10 As shown, the control structure 4 includes a rotary rod 402. The rotary rod 402 is rotatably connected to the inner side of the mounting cylinder 1. The end of the rotary rod 402 has a square structure. The end of the rotary rod 402 is slidably connected to the corresponding push rod 702. The other end of the rotary rod 402 is vertically slidably connected to a drive slide rod 403. The end of the drive slide rod 403 is rotatably connected to a steering slider 404. The steering slider 404 is slidably connected to the inner side of the mounting cylinder 1. The outer side of the mounting cylinder 1 is rotatably connected to a control sleeve 401. A limit groove 407 is opened on the side of the control sleeve 401. The control sleeve 401 abuts against the mounting cylinder 1 through the limit groove 407. A limit rod 405 is fixedly connected to the inner side of the control sleeve 401. A guide groove 406 is opened in the middle of the limit rod 405. The limit rod 405 is slidably connected to the inner side of the mounting cylinder 1. The end of the steering slider 404 is slidably connected to the limit rod 405 through the guide groove 406.

[0047] To facilitate control of the rotation of the push rod 702, a control sleeve 401 is provided on the side of the mounting cylinder 1. The user can rotate the control sleeve 401, and the rotation angle of the control sleeve 401 can be controlled by the limiting groove 407 provided on the control sleeve 401. When the control sleeve 401 rotates, the limiting rod 405 provided on the inner side of the control sleeve 401 will rotate at the same time. At this time, the end of the steering slider 404 will slide on the inner side of the limiting rod 405 through the limiting groove 407, and at the same time drive the steering slider 404 to slide to one side. Furthermore, while the steering slider 404 is sliding, the drive slide rod 403 provided on its side will drive the rotating rod 402 to rotate, which will eventually change the contact state between the push rod 702 and the protrusion 705 on the brake tooth plate 703, thereby controlling the rotation state of the second positioning wheel 207 for convenient use.

[0048] In use, to improve the efficiency and accuracy of optical cable cutting, two first positioning plates 204 and two second positioning plates 206 are arranged inside the mounting cylinder 1. When the optical cable to be cut passes through the mounting cylinder 1, the sliding of the first positioning plates 204 and the second positioning plates 206 inside the mounting cylinder 1, along with the clamping action of the first positioning wheel 205 and the second positioning wheel 207, positions the optical cable at the central axis position of the mounting cylinder 1. To ensure that the first positioning plates 204 and the second positioning plates 206 move synchronously, after the user passes the optical cable to be cut through the mounting cylinder 1, they can rotate the adjusting sleeve 201 located at the end of the mounting cylinder 1. When the adjusting sleeve 201 rotates, it will drive the threaded sliding sleeve 202 to move inward towards the mounting cylinder 1. Multiple inclined push blocks 203 at the end of the threaded sleeve 202 push the first positioning plate 204 and the second positioning plate 206 through the inclined surfaces. This causes the first positioning plate 204 and the second positioning plate 206 to clamp the optical cable in the middle through the first positioning wheel 205 and the second positioning wheel 207. Simultaneously, the placement of the first positioning wheel 205 and the second positioning wheel 207 allows the optical cable to remain in the middle of the mounting cylinder 1 and move freely, facilitating the fixing of optical cables of different specifications and the cutting of the insulation. After the optical cable is cut, to facilitate the removal of the insulation at the end of the optical cable, after the optical cable is fixed by the positioning structure 2, the user can rotate the adjusting gear 301 located on the side of the mounting cylinder 1. The adjusting gear 301 will drive the transmission gear ring 30... 2. Rotation of the transmission gear ring 302 will further drive the two drive gears 303 on both sides and the first screw 304 to rotate simultaneously, thereby adjusting the position of the mounting slider 306 with less effort. The mounting slider 306 is slidably connected to the first positioning plate 204. By adjusting the position of the mounting slider 306, the distance between the first cutting blades 305 on both sides can be adjusted. The end of the first cutting blade 305 has a triangular structure. When the user slowly pulls out the optical cable, the first cutting blade 305 can cut the insulation on the surface of the optical cable, which is convenient for subsequent cleaning of the internal optical fiber. A rotating sleeve 501 is located at the end of the mounting cylinder 1. When it is necessary to cut the optical cable, the user can directly rotate the second screw 50 on the side of the rotating sleeve 501. 2. The second screw 502 drives the first lifting block 506 to slide. Simultaneously, the side rack 505 on the side of the first lifting block 506, through the reversing gear ring 504 in the middle and the side rack 505 on the other side, drives the second lifting block 507 to slide in the opposite direction to the first lifting block 506. Meanwhile, second cutting blades 503 are fixed to the sides of the first lifting block 506 and the second lifting block 507. The user can directly cut the optical cable by adjusting the distance between the two second cutting blades 503. Furthermore, to improve the cutting effect on the optical fiber insulation, the user can also adjust the distance between the second cutting blades 503 before cutting with the first cutting blade 305, so that the second cutting blades 503 can precisely cut the insulation.At this point, combined with the fixing effect of the positioning structure 2, the user can directly rotate the rotating sleeve 501 to achieve circumferential cutting of the outer insulation of the optical cable. Combined with the subsequent cutting effect of the first cutting blade 305, this ensures a clean cut of the insulation and improves the cutting effect on the optical fiber. To facilitate control of the rotation of the rotating sleeve 501, a positioning slide rod 603 is provided on the inner side of the rotating sleeve 501. When the rotating sleeve 501 does not need to be rotated, one end of the positioning slide rod 603 abuts against the mounting cylinder 1 through the positioning groove 604, while the other end of the positioning slide rod 603 directly abuts against the side of the release block 601. Since the positioning slide rod 603 cannot slide, the rotating sleeve 501 cannot rotate at this time. This allows users to perform initial fixing or cutting of the optical cable within the installation cylinder 1. When it is necessary to rotate the rotating sleeve 501 to circumferentially cut the outer insulation of the optical cable, the user can press the release blocks 601 located on both sides of the rotating sleeve 501. At this time, the abutment groove 605 on the side of the release block 601 aligns with the positioning slide rod 603, allowing the positioning slide rod 603 to slide towards the abutment groove 605, thereby releasing the locking state of the rotating sleeve 501 and facilitating the cutting of the optical cable. During the cutting of the optical cable, it can also be fixed to ensure the stability of the cutting. A side toothed ring 701 is provided on each side of the second positioning wheel 207 located on the second positioning plate 206. When the push rod 702 on the second positioning plate 206 rotates, the rod-shaped parts on both sides of the push rod 702 rotate to the top of the protrusion 705, thereby pushing the brake tooth plate 703 to the bottom. This causes the toothed structure on both sides of the brake tooth plate 703 to mesh with the side tooth ring 701, preventing the second positioning wheel 207 from rotating. At this time, combined with the clamping effect of the first positioning wheel 205 on the optical cable, the current position of the optical cable can be fixed, ensuring the fixation of the optical cable when the second cutting blade 503 performs circumferential cutting or severing. To facilitate the control of the rotation of the push rod 702, a control sleeve 401 is provided on the side of the mounting cylinder 1. The user can rotate the control sleeve 401 to... The rotation angle of the control sleeve 401 can be controlled by the limiting groove 407 provided on the control sleeve 401. When the control sleeve 401 rotates, the limiting rod 405 provided on the inner side of the control sleeve 401 will rotate simultaneously. At this time, the end of the steering slider 404 will slide inside the limiting rod 405 through the limiting groove 407, and simultaneously drive the steering slider 404 to slide to one side. Furthermore, while the steering slider 404 is sliding, the drive slide rod 403 provided on its side will drive the rotating rod 402 to rotate, ultimately causing the pushing rod 702 to change the contact state with the protrusion 705 on the brake tooth plate 703, thereby controlling the rotation state of the second positioning wheel 207 for ease of use.
