Description

Technical Field

[0001] The utility model relates to the field of optical cable production devices, in particular to a continuous production type yarn tying machine for optical cables. Background Technique

[0002] An optical cable is a medium for transmitting optical signals. It consists of numerous optical fibers and is wrapped in a protective layer to ensure stable signal transmission. This transmission medium is widely used in multiple fields such as telecommunications, network communication, and radio and television. Yarn tying is a fiber material with high toughness, mainly used to fix the optical fibers inside the optical cable. Its material is usually polyester, with the characteristics of high strength and low thermal shrinkage rate. An optical cable yarn tying machine is a mechanical device specifically designed for optical cable production. During the optical cable production process, it can tightly tie the yarn around the outside of the optical fibers to maintain its structural stability, thereby preventing damage to the optical fibers caused by external forces or signal transmission interruption.

[0003] The existing patent (Publication No.: CN202649566U) "The utility model discloses a continuous production type yarn tying machine for optical cables, including a wire gathering rotating shaft and a hollow rotating shaft. The wire gathering rotating shaft and the hollow rotating shaft are located at the same horizontal position, with one end of the two approaching each other and the other end being installed on a rigid machine base through bearings. The wire gathering rotating shaft and the hollow rotating shaft are respectively driven to rotate by motors. At least two yarn bobbins and flying devices are arranged on the wire gathering rotating shaft and the hollow rotating shaft. The flying device is installed at one end where the wire gathering rotating shaft and the hollow rotating shaft approach each other through a bearing. The flying device includes two symmetrically arranged connecting shafts and a hollow shaft installed on the connecting shafts. The beneficial effect of the utility model is: By setting multiple yarn bobbins, the continuous production time is increased, which not only reduces the operation amount but also improves the productivity."

[0004] In the process of realizing the present application, the inventor found that the prior art has the following problems: Although multiple yarn bobbins are provided in the above comparative technology, the duration of one cycle can be extended, and the frequency of replacing the yarn bobbins can be greatly reduced. However, the number of yarn bobbins replaced at one time is often relatively large, so the time spent on replacing the yarn bobbins each time may still be relatively long. In addition, the production process may need to be paused during the replacement process, and other structures may need to be removed during the replacement process, which may affect the efficiency and continuity of the entire production process.

[0005] Therefore, those skilled in the art provided a continuous production type yarn tying machine for optical cables to solve the problems raised in the above background technique. Content of the Utility Model

[0006] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a continuous production type yarn tying machine for optical cables is proposed. This yarn tying machine can not only effectively control the tension of the yarn but also replace the yarn bobbin by transferring the yarn to ensure the continuity and high efficiency of production.

[0007] To achieve the above object, the utility model provides the following technical solutions:

Fixing plates are fixedly arranged at both front and rear ends close to the upper end of the base. A wire threading hole is formed at a position close to the upper end of one of the two fixing plates close to the rear end. Two central shafts are fixedly arranged on the opposite sides of the two fixing plates. A first rotating shaft is rotatably sleeved outside the two central shafts. An adjusting mechanism is rotatably sleeved at one end close to the wire threading hole outside the two first rotating shafts. Wire changing mechanisms are fixedly arranged at both sides close to the upper end of the base;

[0009] The two adjusting mechanisms each include a second rotating shaft. Connecting rods are fixedly arranged at both the upper and lower ends of the outer surface of the two second rotating shafts. Sliding rods are slidably arranged on the opposite sides between every two of the four connecting rods. Hollow shafts are fixedly arranged on the opposite sides between every two of the four sliding rods;

[0010] Each of the two wire changing mechanisms includes a fixing frame, a support frame and a vertical rod. A limiting frame is rotatably arranged in the middle of each of the two fixing frames. Two turning cylinders are rotatably sleeved at positions close to the upper end of the rod bodies of the two vertical rods.

[0011] Further, the two second rotating shafts are respectively rotatably sleeved at one end close to the wire threading hole on the outer surfaces of the two first rotating shafts.

[0012] Further, springs are fixedly arranged inside each of the four connecting rods. The opposite ends of every two of the four springs are respectively fixedly connected to the sliding rods.

[0013] Further, the two fixing frames are respectively fixedly arranged at positions close to both sides of the upper end of the base. The two vertical rods are respectively fixedly arranged at positions close to both sides of the upper end of the base.

[0014] Further, the two support frames are respectively fixedly arranged at positions close to both sides of the upper end of the base. The two limiting frames are respectively clamped with the two support frames.

[0015] Further, two first motors are fixedly arranged at one end of the upper end of the base far from the wire threading hole.

The support frame fixes the replacement cylinder at a horizontal height, and the rotation of the limiting frame and the clamping connection with the support frame fix the position of the replacement cylinder in the horizontal direction. Then, through the rotation of the wire cylinder, the yarn is transferred from the replacement cylinder to the fixed wire cylinder. Among them, the turning cylinder is used as a transition device to adjust the tension of the first yarn. Such a yarn replenishment method is easy to operate and does not require pausing the production process of the optical cable, ensuring the continuity of the production process and significantly improving the production efficiency.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Refer to Figure 1 , Figure 3 , an embodiment provided by the present invention: A continuous production type optical cable tying machine, including a base 1, a first yarn 14 and a second yarn 15. Fixed plates 2 are fixedly arranged at both ends of the upper end of the base 1 near the front and rear. A wire threading hole 3 is opened at a position near the upper end of one of the two fixed plates 2 close to the rear end. Two central axes 4 are fixedly arranged on the opposite sides of the two fixed plates 2. A first rotating shaft 5 is rotatably sleeved outside the two central axes 4. An adjusting mechanism 6 is rotatably sleeved at one end of the two first rotating shafts 5 near the wire threading hole 3. Wire changing mechanisms 7 are fixedly arranged at both sides of the upper end of the base 1. Two first motors 8 are fixedly arranged at one end of the upper end of the base 1 away from the wire threading hole 3. The output ends of the two first motors 8 are sleeved with first conveyor belts 9. The two first conveyor belts 9 are respectively sleeved between the two first motors 8 and the two first rotating shafts 5. Two second motors 10 are fixedly arranged at one end of the upper end of the base 1 near the wire threading hole 3. The output ends of the two second motors 10 are sleeved with second conveyor belts 11. The two second conveyor belts 11 are respectively sleeved between the two second motors 10 and the two second rotating shafts 601. Replacement cylinders 12 are rotatably sleeved on the outer surfaces of the two support frames 703. Two fixed wire cylinders 13 are fixedly sleeved on the outer parts of the two first rotating shafts 5;

[0030] Specifically, the base 1 supports all the structures at the upper end. The fixing plate 2 fixes the central shaft 4 from both ends. The wire-unifying hole 3 integrates two yarns together. The central shaft 4 is the rotation center of the bobbin and the rotating shaft. The first motor 8 can drive the rotation of the first rotating shaft 5 through the first conveyor belt 9. The rotation of the first rotating shaft 5 can drive the rotation of the bobbin and the second rotating shaft 601. The adjusting mechanism 6 is a structure that can adjust the yarn tension. On the one hand, the adjusting mechanism 6 and the first rotating shaft 5 will rotate relatively. This relative movement can not only effectively control the yarn tension but also ensure the smoothness during the production process. On the other hand, the adjusting mechanism 6 can adjust the position of the hollow shaft 604 according to the rotation speed to adjust the yarn tension. The wire-changing mechanism 7 ensures the continuity of the yarn during the production process by replacing the replacement bobbin 12. The first motor 8 and the first conveyor belt 9 together can drive the rotation of the first rotating shaft 5. The second motor 10 and the second conveyor belt 11 together can drive the rotation of the second rotating shaft 601. The replacement bobbin 12 is a replaceable bobbin, and the fixed bobbin 13 is a non-detachable bobbin. The first yarn 14 will, along with the operation of the device, pass through the turning cylinder 705 from the replacement bobbin 12 and transfer to the fixed bobbin 13. The second yarn 15 will, along with the operation of the device, pass through the hollow shaft 604 from the fixed bobbin 13 and reach the wire-unifying hole 3 to converge with other yarns.

[0031] Referring to Figure 4 、 Figure 5 , the two adjusting mechanisms 6 include the second rotating shafts 601. The two second rotating shafts 601 are respectively rotatably sleeved on the outer surfaces of the two first rotating shafts 5 near one end of the wire-unifying hole 3. Connecting rods 602 are fixedly arranged at the upper and lower ends of the outer surfaces of the two second rotating shafts 601. Sliding rods 603 are slidably arranged on the opposite sides between every two of the four connecting rods 602. Hollow shafts 604 are fixedly arranged on the opposite sides between every two of the four sliding rods 603. Buffer pads 605 are fixedly arranged on the opposite sides between every two of the four connecting rods 602 and on the relative sides between every two of the four sliding rods 603. Springs 606 are fixedly arranged inside the four connecting rods 602. The opposite ends of the four springs 606 are respectively fixedly connected to the sliding rods 603;

[0032] Specifically, the adjustment mechanism 6 can play the role of adjusting the yarn tension, which helps to ensure the smooth operation of the yarn during the production process and the production quality of the optical cable. The second shaft 601 can rotate under the action of the second conveyor belt 11, and at the same time rotate relative to the first shaft 5. Such relative movement can effectively control the tension of the yarn and effectively reduce the pause and waiting time in the production process. The connecting rod 602 is relatively perpendicular to the second shaft 601, and the sliding rod 603 and the hollow shaft 604 are also relatively perpendicular. The sliding rod 603 is slidably sleeved in the second shaft 601. When the second shaft 601 rotates, a certain centrifugal force will be generated. The sliding rod 603 is affected by the elastic force of the spring 606 and the centrifugal force, and then the position of the sliding rod 603 is adjusted, and the hollow shaft 604 moves accordingly. The movement of the hollow shaft 604 can adjust the tension of the yarn. The buffer pad 605 is located between the sliding rod 603 and the connecting rod 602, and can play a buffering and protective role when the sliding rod 603 rebounds.

[0033] Reference Figure 2 , the two line-changing mechanisms 7 each include a fixed frame 701, a support frame 703 and a vertical rod 704, the two fixed frames 701 are respectively fixedly arranged at positions near both sides of the upper end of the base 1, the two vertical rods 704 are respectively fixedly arranged at positions near both sides of the upper end of the base 1, the two support frames 703 are respectively fixedly arranged at positions near both sides of the upper end of the base 1, the two fixed frames 701 are rotatably provided with a limit frame 702 in the middle, the two limit frames 702 are respectively engaged with the two support frames 703, and the two vertical rods 704 are rotatably sleeved with two steering cylinders 705 near the upper ends;

[0034] Specifically, the line changing mechanism 7 is a structure for continuously renewing the line. The fixed frame 701 is used to fix the limiting frame 702. The limiting frame 702 can rotate around the cross bar of the fixed frame 701. The rotation position of the limiting frame 702 can determine the clamping state with the support frame 703. The width of the limiting frame 702 is the same as the width of the replacement cylinder 12. When the limiting frame 702 is clamped with the support frame 703, the replacement cylinder 12 can be stably fixed at the specified position of the support frame 703, ensuring that the replacement cylinder 12 can stably rotate around the support frame 703 during the production process. The vertical rod 704 is perpendicular to the base 1, and the steering cylinder 705 can rotate around the vertical rod 704 when subjected to force. The steering cylinder 705 can temporarily wrap a small part of the yarn, which plays a buffering role between the replacement cylinder 12 and the fixed wire cylinder 13, ensuring the smoothness and stability of the yarn transfer process.

[0035] Working principle: When the user uses this yarn tying machine, start the first motor 8 and the second motor 10. Among them, the first yarn 14 is originally wound around the replacement cylinder 12, wind it around the turning cylinder 705 for several turns, and then fix the yarn end to the fixed cylinder 13. The first motor 8 drives the first rotating shaft 5 to rotate through the first conveyor belt 9. The rotation of the first rotating shaft 5 can drive the rotation of the fixed cylinder 13, and the first yarn 14 will be continuously wound around the fixed cylinder 13 as it rotates, completing the transfer of the yarn from the replacement cylinder 12 to the fixed cylinder 13. And the second yarn 15 is wound around another fixed cylinder 13 on the same first rotating shaft 5. The second yarn 15 passes through the hollow shaft 604 and the yarn threading hole 3 in sequence. The rotation of the fixed cylinder 13 can drive the movement of the yarn, thereby ensuring the production of the optical cable;

[0036] Secondly, the second motor 10 drives the rotation of the second rotating shaft 601 through the second conveyor belt 11. The second rotating shaft 601 and the first rotating shaft 5 will generate relative rotation, effectively controlling the tension of the second yarn 15. At the same time, a certain centrifugal force is generated during the rotation of the second rotating shaft 601. The combined action of the centrifugal force and the elastic force of the spring 606 can drive the sliding rod 603 to slide along the connecting rod 602, adjusting the position of the hollow shaft 604, and further adjusting the yarn tension to ensure the smoothness of the production process;

[0037] Finally, when the transfer of the yarn on the replacement cylinder 12 is completed, rotate the limit frame 702, remove the replacement cylinder 12 from the support frame 703, replace it with a new replacement cylinder 12, and re - clamp the limit frame 702 to the support frame 703. Without stopping the production of the front - end optical cable, the yarn can be replenished, ensuring the continuity of the production process.

[0038] Finally, it should be noted that the above - mentioned are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
