[0031] The optical cable production equipment 10 according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0032] Reference Figures 1-3 As shown, the optical cable production equipment 10 according to an embodiment of the present invention includes an optical cable extruder 1, an optical cable cooler 2, and an optical cable retractor 3. The optical cable extruder 1 is used to extrude optical cables 20, and the optical cable retractor 3 is used to retract the optical cables 20. The optical cable cooler 2 is disposed between the optical cable extruder 1 and the optical cable retractor 3. The optical cable cooler 2 includes: a housing 21, a filter plate 22, a drive component 23, a spray head 24, and a liquid suction pump 25. The housing 21 has a spray tank 211 and a liquid storage tank 212. The optical cable 20 passes through the spray tank 211. The filter plate 22 has at least a portion of its components in the spray tank 211. The filter plate 22 is separated into a communication space 2121 and a storage space 2122 within the storage tank 212. The communication space 2121 is located above the storage space 2122 and communicates with the spray tank 211. The drive unit 23 is used to drive the filter plate 22 to vibrate. The spray head 24 is at least partially located within the spray tank 211. The spray head 24 is connected to the storage space 2122 via a suction pump 25. The suction pump 25 is used to pump the coolant in the storage space 2122 to the spray head 24 so that the spray head 24 sprays coolant onto the optical cable 20 in the spray tank 211.

[0033] Specifically, the optical cable extruder 1 is used to extrude the optical cable 20. The optical cable extruder 1 can process optical fibers, reinforcing elements, sheath materials, etc. into optical cables 20 for communication. The optical cable extruder 1 can realize functions such as optical fiber coloring, bundle tube forming, cable core stranding, and sheath covering. After the optical cable extruder 1 extrudes the optical cable 20, the optical cable reel 3 can reel in the extruded optical cable 20 so that the optical cable 20 is wound on the optical cable reel 3, so as to facilitate the storage, transportation and use of the optical cable 20.

[0034] The optical cable 20 extruded by the optical cable extruder 1 is at a high temperature and needs to be cooled before winding. At the same time, the extruded optical cable 20 has debris, oil and other impurities on its exterior, which need to be cleaned. The optical cable cooler 2 is located between the optical cable extruder 1 and the optical cable winder 3. The optical cable cooler 2 can cool and clean the optical cable 20 extruded by the optical cable extruder 1 to ensure the production quality of the optical cable 20 and prevent the optical cable 20 from sticking to the optical cable winder 3 or carrying in impurities.

[0035] The optical cable cooler 2 sprays coolant onto the extruded optical cable 20 to cool and clean it. The optical cable cooler 2 includes: a housing 21, a filter plate 22, a drive unit 23, a spray head 24, and a suction pump 25. The housing 21 has a spray tank 211 and a liquid storage tank 212, which can be integrally molded. The spray tank 211 can be connected to the upper end of the liquid storage tank 212. The filter plate 22 is at least partially disposed within the liquid storage tank 212 to cool and clean the liquid storage tank. 212 is divided into a connecting space 2121 and a liquid storage space 2122. The connecting space 2121 is located above the liquid storage space 2122 and is connected to the spray tank 211. That is to say, the spray tank 211, the connecting space 2121, the filter plate 22 and the liquid storage space 2122 can be arranged sequentially from top to bottom so that the coolant in the spray tank 211 can flow sequentially through the connecting space 2121 and the filter plate 22 under the action of gravity, and then pass through the filter plate 22 into the liquid storage space 2122.

[0036] The optical cable 20 is run through the spray tank 211, and the spray head 24 is at least partially located in the spray tank 211. The spray head 24 is connected to the liquid storage space 2122 through the liquid suction pump 25. The liquid storage space 2122 can be used to store coolant. The spray tank 211 can be used to collect the coolant sprayed by the spray head 24 onto the optical cable 20 to avoid coolant splashing. The connecting space 2121 connects the spray tank 211 and the liquid storage space 2122 so that the coolant collected in the spray tank 211 can flow back to the liquid storage space 2122 through the connecting space 2121, realizing the recycling of coolant and reducing the consumption of coolant. The filter plate 22 is located between the connecting space 2121 and the liquid storage space 2122. When the coolant flows from the connecting space 2121 through the filter plate 22 to the liquid storage space 2122, the filter plate 22 can filter the impurities carried by the coolant scouring the optical cable 20, so as to realize the recycling of the coolant. At the same time, it can also prevent impurities from clogging the suction pump 25 and the spray head 24, thereby improving the service life and reliability of the suction pump 25 and the spray head 24.

[0037] The drive unit 23 can drive the filter plate 22 to vibrate, so that the coolant can pass through the filter plate 22 quickly, thereby improving the filtration efficiency of the filter plate 22 for the coolant. At the same time, the vibration of the filter plate 22 can separate impurities from it, thereby preventing the impurities filtered out by the filter plate 22 from clogging the filter plate 22 and extending the service life of the filter plate 22.

[0038] Understandably, after the optical cable 20 is extruded by the optical cable extruder 1, it first passes through the spray tank 211 and is then wound up by the optical cable retractor 3. When the optical cable 20 passes through the spray tank 211, the liquid suction pump 25 pumps the coolant in the liquid storage space 2122 to the spray head 24. The spray head 24 sprays the coolant onto the optical cable 20 in the spray tank 211. The coolant can cool and clean the optical cable 20. After the coolant sprayed by the spray head 24 washes the optical cable 20, it is collected by the spray tank 211 and then flows to the connecting space 2121. It is then filtered by the filter plate 22 below the connecting space 2121. The connecting space 2121 can store the coolant to be filtered to prevent the coolant from overflowing. At the same time, the drive unit 23 drives the filter plate 22 to vibrate so that the coolant can quickly flow back to the liquid storage space 2122 through the filter plate 22, realizing the recycling of the coolant.

[0039] According to the embodiment of the present invention, the optical cable production equipment 10 has an optical cable cooler 2 located between the optical cable extruder 1 and the optical cable retractor 3. The optical cable cooler 2 can cool and clean the optical cable 20. The optical cable cooler 2 is equipped with a filter plate 22 to filter impurities in the coolant, realize the recycling of the coolant, and prevent the spray head 24 and the suction pump 25 from clogging. The optical cable cooler 2 is also equipped with a drive component 23 to drive the filter plate 22 to vibrate, so as to improve the filtration efficiency of the filter plate 22 and prevent the filter plate 22 from clogging. This helps to reduce the failure rate of the optical cable production equipment 10, reduce maintenance costs and downtime for maintenance, improve the production efficiency of the optical cable 20, and reduce the production cost of the optical cable 20.

[0040] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 As shown, the spray head 24 includes a spray conduit 241 and a spray ring 242. The spray conduit 241 is fixed in the spray tank 211 and is connected to the liquid suction pump 25. The spray ring 242 is connected to the spray conduit 241 and is sleeved in the spray tank 211 on the radial outer side of the optical cable 20. The spray ring 242 has a plurality of spray holes 2421, which are arranged at intervals along the circumferential direction of the spray ring 242, and each spray hole 2421 faces the optical cable 20.

[0041] Specifically, the spray head 24 includes a spray conduit 241 and a spray ring 242. The spray conduit 241 can be inserted and fixed in the spray trough 211. The extension direction of the spray conduit 241 can be the same as the direction in which the optical cable 20 passes through the spray trough 211, that is, the extension direction of the spray conduit 241 is... Figure 2 In the left and right direction, the spray ring 242 can be fixed to the spray conduit 241. The spray conduit 241 is connected to the suction pump 25, and the spray ring 242 is connected to the spray conduit 241. The suction pump 25 can pump coolant to the spray ring 242 through the spray conduit 241.

[0042] The spray ring 242 is fitted inside the spray groove 211 on the radial outer side of the optical cable 20. The spray ring 242 has multiple spray holes 2421, which are arranged at intervals along the circumferential direction of the spray ring 242. Each spray hole 2421 faces the optical cable 20. Thus, the spray ring 242 can spray the optical cable 20 from multiple angles and directions on the outer periphery of the optical cable 20 through multiple different spray holes 2421, which helps to improve the cooling and cleaning effect of the optical cable 20.

[0043] In some embodiments of this utility model, reference is made to Figure 2 As shown, there are multiple spray rings 242. Along the moving direction of the optical cable 20 in the spray tank 211, the multiple spray rings 242 are arranged at intervals. That is, the multiple spray rings 242 are arranged at intervals in the left and right direction. When the optical cable 20 passes through the spray tank 211 from left to right, it can pass through each spray ring 242 in sequence, which can realize multiple cooling and cleaning of the optical cable 20, so as to further improve the cooling and cleaning effect of the optical cable 20.

[0044] In some other embodiments of the present invention (not shown in the figures), the spray head 24 may be configured as a spiral nozzle surrounding the optical cable 20, the spiral nozzle having a plurality of spray holes facing the optical cable 20 to ensure cooling and cleaning of the optical cable 20.

[0045] In some embodiments of this utility model, reference is made to Figures 1-3 As shown, the filter plate 22 is inclined relative to the horizontal plane, and the liquid storage tank 212 has an impurity discharge port 2123 at the lowest end of the filter plate 22.

[0046] Specifically, the filter plate 22 is inclined relative to the horizontal plane, that is, one end of the filter plate 22 is higher than the other end of the filter plate 22. The liquid storage tank 212 has an impurity discharge port 2123 at the lowest end of the filter plate 22. When the driving component 23 drives the filter plate 22 to vibrate, the impurities can move along the inclined direction of the filter plate 22. The impurities can enter the impurity discharge port 2123 from the lowest end of the filter plate 22, so that the impurities are discharged to the outside of the housing 21 through the impurity discharge port 2123, thereby realizing the self-cleaning function of the filter plate 22, reducing the maintenance of the filter plate 22, and extending the service life of the filter plate 22.

[0047] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 As shown, the optical cable production equipment 10 also includes an impurity collection tank 27, which is detachably connected to the liquid storage tank 212, and the opening of the impurity collection tank 27 is located below the impurity discharge outlet 2123.

[0048] Specifically, the impurity collection tank 27 can be detachably connected to the liquid storage tank 212 through a structure such as a slot, fastener, or slide. The opening of the impurity collection tank 27 is located below the impurity discharge outlet 2123. After the impurities are discharged through the impurity discharge outlet 2123, they can fall into the impurity collection tank 27 to collect the impurities and prevent them from splashing. When there are many impurities in the impurity collection tank 27, the impurity collection tank 27 can be removed, the impurities inside can be poured out, and then it can be reinstalled into the liquid storage tank 212.

[0049] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 As shown, the lowest end of the filter plate 22 extends out of the impurity discharge port 2123. In the vertical direction, the projection of the lowest end of the filter plate 22 onto the impurity collection tank 27 is located inside the impurity collection tank 27, so that the impurities on the filter plate 22 can fall downward into the impurity collection tank 27, avoiding the accumulation of impurities at the impurity discharge port 2123.

[0050] In some embodiments of this utility model, reference is made to Figures 1-3 As shown, the driving component 23 includes a driving motor 231 and a cam 232. The driving motor 231 is fixed to the liquid storage tank 212, and one end of the outer peripheral surface of the cam 232 abuts against the lower surface of the filter plate 22. The cam 232 is connected to the driving motor 231 in a transmission manner.

[0051] Specifically, the drive motor 231 can drive the cam 232 to rotate. The outer contour of the cam 232 can be elliptical. When the cam 232 rotates, the contact position between the lower surface of the filter plate 22 and the outer peripheral surface of the cam 232 changes continuously, so that the cam 232 drives the filter plate 22 to vibrate.

[0052] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 As shown, at least a portion of the drive motor 231 is fixed to the outside of the reservoir 212. The drive component 23 also includes a connecting shaft 233. The drive motor 231 is connected to the cam 232 via the connecting shaft 233 to reduce the risk of coolant entering the drive motor 231. Optionally, both ends of the connecting shaft 233 are rotatably inserted through the reservoir 212 to improve the stability of the connecting shaft 233.

[0053] Reference Figure 3 As shown, the front end of the filter plate 22 is higher than the rear end of the filter plate 22. The rear side of the liquid storage tank 212 is provided with an impurity discharge port 2123 corresponding to the rear end of the filter plate 22. The front end of the filter plate 22 can be hinged in the liquid storage tank 212. The outer peripheral surface of the cam 232 abuts against the lower surface of the filter plate 22 near the impurity discharge port 2123.

[0054] In some other embodiments of the present invention (not shown in the figure), the inner wall of the liquid storage tank 212 may be provided with an annular groove for placing the filter plate 22. The filter plate 22 overlaps on the annular groove, and the filter plate 22 is in clearance fit with the annular groove so that the filter plate 22 can vibrate in the annular groove.

[0055] It should be noted that the structure of the driving component 23 is not limited to this. The driving component 23 can also be an electromagnet vibrator, a pneumatic vibrator, etc.

[0056] In some embodiments of this utility model, reference is made to Figure 3 and Figure 5 As shown, the liquid storage tank 212 has a liquid injection hole 2124, which communicates with the liquid storage space 2122. Coolant can be injected into the liquid storage space 2122 through the liquid injection hole 2124 to facilitate the addition of coolant to the liquid storage space 2122. A liquid injection pipe 2125 is inserted into the liquid injection hole 2124, through which coolant flows into the liquid injection hole 2124.

[0057] Reference Figure 2 As shown, optical cable through holes 2111 are provided at both ends of the spray tank 211 near the optical cable extruder 1 and the optical cable retractor 3. The diameter of the optical cable through hole 2111 is larger than the diameter of the optical cable 20. The optical cable 20 passes through the optical cable through hole 2111 and passes through the spray tank 211.

[0058] Reference Figure 2 and Figure 3 As shown, the suction pump 25 is fixed to the liquid storage tank 212. The inlet of the suction pump 25 is located in the liquid storage space 2122, and the outlet of the suction pump 25 is located outside the liquid storage tank 212 and is connected to the spray head 24 through the connecting pipe 26. The connecting pipe 26 is located outside the liquid storage tank 212 to avoid interference between the connecting pipe 26 and the filter plate 22.

[0059] In some embodiments of this utility model, the filter plate 22 may include a filter mesh layer and a filter paper layer stacked together. The filter mesh layer may be a metal mesh structure. The filter paper layer is detachably connected to the filter mesh layer. The filter mesh layer can support and fix the filter paper layer and has good water permeability. The filter paper layer can filter impurities and adsorb grease. The filtration effect of the filter plate 22 can be maintained by replacing the filter paper layer.

[0060] In some embodiments of this utility model, reference is made to Figure 2 , Figure 4 and Figure 5As shown, the optical cable retractor 3 includes: a support frame 31, a drive shaft 32, a retracting motor 33, and a retracting roller 34. The support frame 31 has a support hole 311. The drive shaft 32 is rotatably inserted through the support hole 311. The retracting motor 33 is fixed to the support frame 31 and is connected to the drive shaft 32. The retracting roller 34 is detachably connected to the drive shaft 32. The retracting motor 33 drives the retracting roller 34 to rotate through the drive shaft 32 so that the optical cable 20 is wound on the retracting roller 34.

[0061] Specifically, the winding motor 33 can be fixed to the support frame 31 by fasteners or a motor sleeve 35. The support frame 31 has a support hole 311, through which the drive shaft 32 rotatably passes. The support hole 311 supports the drive shaft 32. A bearing or bushing can be provided between the drive shaft 32 and the support hole 311 to reduce wear between them. The winding motor 33 can be directly connected to the drive shaft 32, or it can be indirectly connected to the drive shaft 32 via a coupling. The drive motor 33 can drive the drive shaft 32 to rotate. The drive motor 33 drives the winding roller 34 to rotate through the drive shaft 32, so that the optical cable 20 is wound on the winding roller 34, realizing the winding operation of the optical cable 20 and providing continuous traction force for the winding of the optical cable 20. The winding roller 34 is detachably connected to the drive shaft 32. When the optical cable 20 on the winding roller 34 is fully wound, the winding roller 34 with the full optical cable 20 can be removed from the drive shaft 32, and then an empty winding roller 34 can be installed on the drive shaft 32.

[0062] In some embodiments of this utility model, reference is made to Figure 2 and Figure 4 As shown, the optical cable retractor 3 also includes a quick-release frame 36, which is opposite to and spaced apart from the support frame 31. The quick-release frame 36 includes a frame body 361, a support arm 362, and a telescopic arm 363. One end of the support arm 362 is hinged to one end of the telescopic arm 363, and the other ends of the support arm 362 and the telescopic arm 363 are both hinged to the frame body 361. The telescopic arm 363 drives the support arm 362 to rotate to the support position and the dismount position by extending and retracting. In the support position, the support arm 362 supports the end of the drive shaft 32 away from the support frame 31. In the dismount position, the support arm 362 releases the support of the drive shaft 32.

[0063] Specifically, in the axial direction of the drive shaft 32, that is Figure 2 In the front and rear, the quick-release frame 36 can be opposite to the support frame 31 and the two are spaced apart. The telescopic arm 363 of the quick-release frame 36 can be extended and retracted to drive the support arm 362 to rotate relative to the frame body 361.

[0064] When the support arm 362 rotates to the support position, the support arm 362 can be parallel to the horizontal plane. The support arm 362 supports the end of the drive shaft 32 away from the support frame 31 to ensure the stability of the drive shaft 32 and prevent the drive shaft 32 from shaking and affecting the winding quality of the optical cable 20.

[0065] When the support arm 362 rotates from the supporting position to the disassembly position, the length of the telescopic arm 363 shortens. The telescopic arm 363 drives the support arm 362 to rotate downward. The support arm 362 rotates around its hinge point with the frame body 361, and the end of the support arm 362 that is hinged to the telescopic arm 363 moves downward, thereby releasing the support arm 362 from the drive shaft 32. At this time, the support arm 362 is offset from the drive shaft 32 in the axial direction, so as to facilitate the assembly and disassembly of the winding roller 34 fully wound with optical cable 20 in the axial direction of the drive shaft 32. The quick-release frame 36 can facilitate the quick assembly and disassembly of the winding roller 34, effectively reducing the cumbersome steps of replacing the winding roller 34 and significantly improving work efficiency.

[0066] In some embodiments of this utility model, the telescopic arm 363 can be an electric telescopic arm or a hydraulic telescopic arm.

[0067] In some embodiments of this utility model, reference is made to Figure 4 As shown, the support arm 362 has a support groove 3621. In the supported position, the end of the drive shaft 32 away from the support frame 31 is rotatably connected to the support groove 3621. The support groove 3621 can support and limit the drive shaft 32 to reduce the risk of the drive shaft 32 coming off the support groove 3621.

[0068] In some embodiments of this utility model, a bearing bush is provided in the support groove 3621. The bearing bush can reduce the wear of the support groove 3621 and the transmission shaft 32, and improve the service life of the support arm 362 and the transmission shaft 32.

[0069] Reference Figure 4 and Figure 5 As shown, the drive shaft 32 includes a shaft body 321 and a limiting sleeve 322. The limiting sleeve 322 is sleeved on the radially outer side of the shaft body 321 and has at least one radial protrusion 3221. The take-up roller 34 has guide limiting grooves 341 corresponding to the radial protrusions 3221. In the axial direction of the drive shaft 32, the guide limiting grooves 341 guide and cooperate with the corresponding radial protrusions 3221. The guide limiting grooves 341 can slide on the radial protrusions 3221 in the axial direction of the drive shaft 32 to facilitate the installation and removal of the take-up roller 34. In the circumferential direction of the drive shaft 32, the guide limiting grooves 341 limit and cooperate with the corresponding radial protrusions 3221 to make the take-up roller 34 rotate synchronously with the shaft body 321 and the limiting sleeve 322, thus preventing the take-up roller 34 from slipping.

[0070] Reference Figure 2 As shown, the frame body 361 can be an L-shaped bracket to reduce the risk of interference between the frame body 361 and the support arm 362 and the telescopic arm 363. The lower ends of the frame body 361 and the support frame 31 can be connected by a connecting bracket 37 to improve the stability of the frame body 361 and the support frame 31.

[0071] In some embodiments of this utility model, reference is made to Figure 1 As shown, the optical cable production equipment 10 also includes a substrate 4, on which the optical cable extruder 1, optical cable winder 3, and optical cable cooler 2 are all mounted.

[0072] Specifically, the substrate 4 can be a flat plate structure. The optical cable extruder 1, the optical cable retractor 3, and the optical cable cooler 2 can all be mounted on the upper surface of the substrate 4. The substrate 4 can connect the optical cable extruder 1, the optical cable retractor 3, and the optical cable cooler 2 into a whole, so as to facilitate the handling and use of the optical cable production equipment 10.
