Description

Technical Field

[0001] The present invention relates to the technical field of optical cable production, and in particular to an optical cable production device. Background Art

[0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. They are communication cable components that use one or more optical fibers placed in a protective sheath as transmission media and can be used individually or in groups. Optical cables are mainly composed of optical fibers, plastic protective sheaths and plastic sheaths. The optical fiber in the optical cable is the most core component. The optical fiber is very sensitive to water and moisture. Water and moisture can expand cracks on the surface of the optical fiber, resulting in a decrease in the strength of the optical fiber and even an increase in optical fiber transmission loss, which seriously affects the quality and service life of the optical cable.

[0003] In order to improve the waterproof and moisture-proof performance of optical fibers, oil is usually applied to the surface of optical fibers during the production process of optical cables. In order to ensure the oiling effect of the optical cable, dust or water vapor on the surface of the optical fiber needs to be removed before the optical fiber is oiled. For example, an optical cable production device and production method disclosed in application number 202010362066.0 uses a cleaning brush to clean the surface of the optical fiber. However, impurities or water vapor cleaned from the surface of the optical fiber may adhere to and accumulate on the cleaning brush, resulting in a weaker continuous cleaning ability of the cleaning brush on the optical fiber, reducing the cleaning effect on the optical fiber.

[0034] Furthermore, the technical solutions between the various embodiments of the present application may be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in the field. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0035] like Figure 1-Figure 4 As shown, the embodiment of the present application provides an optical cable production device, including a support 100, a rotating shell 200, a driving mechanism 300, a cleaning belt 400 and a reeling and unreeling mechanism 500. The rotating shell 200 is a circular shell structure, and a connecting ring 210 is provided on one side of the rotating shell 200. The rotating shell 200 is rotatably mounted on the support 100 through the connecting ring 210. The interior of the rotating shell 200 has a cavity 220 for installing the cleaning belt 400 and the reeling and unreeling mechanism 500. The rotating shell 200 is provided with a through hole 230 connected to the cavity 220. The optical fiber 700 can enter and exit the cavity 220 through the through hole 230 and penetrate the rotating shell 200. The driving mechanism 300 is used to drive the rotating shell 200 to rotate.

[0036] The cleaning belt 400 is installed in the cavity 220 in a flowable manner. The cleaning belt 400 can contact a portion of the optical fiber 700 passing through the cavity 220, and the continuously transmitted optical fiber 700 is cleaned by the cleaning belt 400. In addition, the flow direction of the cleaning belt 400 is perpendicular to the travel direction of the optical fiber 700, so that the contact part between the cleaning belt 400 and the optical fiber 700 can be continuously updated to ensure the cleaning effect. The reeling and unreeling mechanism 500 is installed in the cavity 220, connected to both ends of the cleaning belt 400, and is used for the unreeling and reeling operations of the cleaning belt 400, providing support and power for the flow of the cleaning belt 400.

[0037] Through the above technical solution, before the optical fiber 700 is oiled, the optical fiber 700 is first passed through the rotating shell 200 through the through hole 230, so that the optical fiber 700 contacts the cleaning belt 400, and then the rotating shell 200 is driven to rotate by the driving mechanism 300, so that the cleaning belt 400 can also rotate around the optical fiber 700, so as to clean the continuously transmitted optical fiber 700; at the same time, the reeling and unreeling mechanism 500 can drive the cleaning belt 400 to flow, and the flow direction of the cleaning belt 400 is perpendicular to the travel direction of the optical fiber 700, so that the contact part between the cleaning belt 400 and the optical fiber 700 can be continuously updated to ensure the continuous cleaning effect of the cleaning belt 400 on the optical fiber 700, and each area on the cleaning belt 400 can contact the optical fiber 700, thereby improving the utilization rate of the cleaning belt 400.

[0038] In addition, it should be noted that the rotation speed of the rotating shell 200 needs to be adjusted according to the travel speed of the optical fiber 700 , which is not specifically limited in this embodiment, and it is only necessary to ensure that the surface of the optical fiber 700 can contact the cleaning belt 400 .

[0039] In a possible embodiment, the cleaning tape 400 can be made of paper material or cloth material. If the cleaning tape 400 is made of paper material, it is usually a disposable consumable; if the cleaning tape 400 is made of cloth material, it can be recycled.

[0040] In a possible embodiment, the rotating shell 200 is installed with a plurality of unloading side guide rollers 240, a plurality of receiving side guide rollers 250 and a plurality of face-changing guide rollers 260 in the cavity 220, and all the guide rollers are rotatably installed in the cavity 220. The unloading side guide rollers 240 and the receiving side guide rollers 250 are symmetrically arranged on both sides of the optical fiber 700. At least two unloading side guide rollers 240 are arranged, and the axes of all unloading side guide rollers 240 are located in the same plane. At least two receiving side guide rollers 250 are also arranged, and the axes of all receiving side guide rollers 250 are located in the same plane. At least four face-changing guide rollers 260 are arranged, one of which is close to the unloading side guide roller 240, and the remaining distribution positions are close to the receiving side guide roller 250. The specific installation position can be set according to actual conditions. The cleaning belt 400 is sequentially sleeved on the unwinding side guide roller 240, the face-changing guide roller 260 and the receiving side guide roller 250 along the flow direction, so that the front and back sides of the cleaning belt 400 are in contact with the optical fiber 700 respectively.

[0041] It should be noted that the cleaning belt 400 sleeved on the guide roller 240 on the unwinding side and the cleaning belt 400 sleeved on the guide roller 250 on the receiving side can both contact the optical fiber 700. The face-changing guide roller 260 can guide the cleaning belt 400 to change direction, so that the side of the cleaning belt 400 sleeved on the guide roller 240 on the unwinding side that contacts the optical fiber 700 is different from the side of the cleaning belt 400 sleeved on the guide roller 250 on the receiving side that contacts the optical fiber 700. In addition, under the action of all guide rollers, the cleaning belt 400 can also be in a tensioned state.

[0042] Through the above technical solution, both the front and back sides of the cleaning tape 400 can contact the optical fiber 700, so that both the front and back sides of the cleaning tape 400 can clean the optical fiber 700, thereby improving the utilization rate of the cleaning tape 400.

[0043] In a possible embodiment, the unwinding and rewinding mechanism 500 includes a discharge wheel 510, a take-up wheel 520, and a transmission assembly 530. The discharge wheel 510 and the take-up wheel 520 are both rotatably mounted in the cavity 220, and the transmission assembly 530 is used to drive the take-up wheel 520 to rotate. The discharge end of the cleaning tape 400 is wound on the discharge wheel 510, and the take-up end of the cleaning tape 400 is wound on the take-up wheel 520. By driving the take-up wheel 520 to rotate through the transmission assembly 530, the cleaning tape 400 can be driven to continuously flow between the discharge wheel 510 and the take-up wheel 520.

[0044] In a possible embodiment, since there is not too much dust and water vapor on the optical fiber 700, the flow update speed of the cleaning belt 400 does not need to be too fast, and in order to reduce costs and energy, the transmission assembly 530 includes a transmission gear 531 and a transmission rack 532. The transmission gear 531 is connected to the receiving wheel 520 in a transmission manner, and when the transmission gear 531 rotates, the receiving wheel 520 can be driven to rotate. The transmission rack 532 is fixed to the bracket 100 and is located on the motion track of the transmission gear 531. When the transmission gear 531 meets the transmission rack 532, the transmission gear 531 can mesh with the transmission rack 532.

[0045] Through the above technical solution, when the rotating shell 200 rotates one circle, the transmission gear 531 can meet the transmission rack 532. Through the mutual engagement of the transmission gear 531 and the transmission rack 532, the receiving wheel 520 is driven to rotate a certain angle, thereby realizing the flow renewal of the cleaning belt 400.

[0046] In other embodiments, if cost and energy are not considered, the transmission assembly 530 can directly use an electric drive such as a servo motor or a stepper motor. In addition, the unloading wheel 510 and the receiving wheel 520 can each be equipped with an electric drive, and the unloading operation of the unloading wheel 510 and the receiving operation of the material wheel 520 can be achieved through the cooperation of the two electric drives.

[0047] In a possible embodiment, in order to ensure that the unloading wheel 510 and the receiving wheel 520 do not rotate at will and can only rotate under the drive of the transmission assembly 530, rubber pads are installed on the sides of the unloading wheel 510 and the receiving wheel 520, and the rubber pads are against the inner wall of the cavity 220. The rubber pads can have a good anti-slip effect, so that the unloading wheel 510 and the receiving wheel 520 will not rotate at will, and prevent the cleaning belt 400 from loosening.

[0048] In a possible embodiment, the driving mechanism 300 includes a driving gear 310, an annular rack 320 and a driving motor 330. The driving motor 330 is fixedly mounted on the bracket 100 by bolts, and the driving motor 330 can be a servo motor or a stepping motor. The driving gear 310 is keyed to the output shaft of the driving motor 330. The annular rack 320 is fixedly mounted on the outer wall of the rotating shell 200 close to the bracket 100, and meshes with the driving gear 310. The driving motor 330 can drive the driving gear 310 to rotate, and then the rotating shell 200 is driven to rotate through the mutual meshing of the driving gear 310 and the annular rack 320, so that the cleaning belt 400 rotates around the optical fiber 700 to clean the optical fiber 700.

[0049] In another embodiment, the driving mechanism 300 may also use a driving motor 330 in combination with a belt drive, a chain drive, etc., which can realize the rotational movement of the rotating shell 200.

[0050] In a possible embodiment, in order to facilitate opening the cavity 220 of the rotating shell 200, disassembling, maintaining or repairing the internal parts and the cleaning belt 400, the rotating shell 200 is provided with an opening on the side of the cavity 220 away from the bracket 100, and the rotating shell 200 is installed with a cover plate 270 on the open side. Two cover plates 270 are provided, and the two cover plates 270 are arranged symmetrically. In addition, there is also a through hole 230 for the optical fiber 700 to pass through between the two cover plates 270. The cover plate 270 can be installed on the rotating shell 200 by a connection method such as a buckle, a bolt, etc., or it can be installed on the rotating shell 200 by a double door. This embodiment is not specifically limited, and it only needs to facilitate the staff to open the cavity 220 of the rotating shell 200. In addition, the cover plate 270 can be made of a transparent material, so that the staff can view the situation inside the cavity 220 of the rotating shell 200 in real time.

[0051] In a possible embodiment, in order to facilitate the replacement of the cleaning belt 400, the rotating shell 200 is rotatably mounted with two rotating shafts 280 in the cavity 220, and the two rotating shafts 280 are respectively adapted to the discharge wheel 510 and the receiving wheel 520. A connecting key is integrally formed on the rotating shaft 280, and the connecting key extends along the axial direction of the rotating shaft 280. The middle part of the discharge wheel 510 and the receiving wheel 520 is provided with a connecting hole adapted to the rotating shaft 280, and the inner side wall of the connecting hole is provided with a keyway adapted to the connecting key. When the rotating shaft 280 is inserted into the connecting hole of the discharge wheel 510 or the receiving wheel 520, the connecting key can enter the keyway to realize the key connection between the rotating shaft 280 and the discharge wheel 510 or the receiving wheel 520. When the cleaning tape 400 needs to be replaced, the cover plate 270 can be opened, the unloading wheel 510 and the receiving wheel 520 can be directly removed, and replaced with new unloading wheel 510 and receiving wheel 520, on which new cleaning tape 400 is wound. In addition, it should be noted that the transmission gear 531 is installed on the rotating shaft 280 adapted to the receiving wheel 520.

[0052] In a possible embodiment, the optical cable production equipment further includes an oiling mechanism 600 for oiling the optical fiber 700. The oiling mechanism 600 includes an annular oil spray pipe 610 and an oil pump 620. The inner ring of the annular oil spray pipe 610 is provided with a plurality of evenly arranged oil spray nozzles 611, which are connected to the annular oil spray pipe 610, and the oil spraying end of the oil spray nozzle 611 faces the center of the annular oil spray pipe 610, and the optical fiber 700 can pass through the plurality of oil spray nozzles 611. The oil inlet end of the oil pump 620 is connected to an external oil supply device through a pipeline, and the oil outlet end is connected to the annular oil spray pipe 610 through a pipeline. By such an arrangement, after cleaning the optical fiber 700, the oil of the oil supply device can be transported to the annular oil spray pipe 610 by the power of the oil pump 620, and finally sprayed to the optical fiber 700 through the oil spray nozzle 611, thereby completing the oiling operation of the optical fiber 700.

[0053] In a possible embodiment, the oiling mechanism 600 further includes a recovery container 630, which is a hollow structure with an open top side, and the open side of the recovery container 630 is located at the lower side of the annular oil spraying pipe 610, and the annular oil spraying pipe 610 can be fixed to the recovery container 630 by a connecting rod. The recovery container 630 is provided to recover the oil applied to the optical fiber 700, and the oil can be reused after subsequent processing.
