Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of optical cable, in particular to a water-blocking cable paste coating device for optical cable core. BACKGROUND

[0002] The information disclosed in this BACKGROUND section is only for the purpose of enhancing the understanding of the general background of the present application and does not suggest or imply that the information forms any part of the prior art base to the present application.

[0003] With the continuous development and application of communication optical cable, the long-term reliability of optical cable is paid more and more attention. In the long-term use process, due to the erosion of moisture and water, the transmission performance will be reduced, which will affect the normal use. In the production of optical cable, the water-blocking materials of the core mainly have two categories, one is water-blocking filling paste, and the other is water-blocking tape and water-blocking yarn. Since the water-blocking filling paste (hereinafter referred to as water-blocking cable paste) can play a good waterproof, moisture-proof, buffering and bonding role in production, it has good reliability and convenient maintenance, therefore, the water-blocking cable paste is widely used in optical cable production. In the manufacturing process of OPGW optical cable, a layer of water-blocking cable paste needs to be coated on the inner layer of the core steel wire to isolate the optical fiber sleeve from the external erosion source. However, the traditional water-blocking cable paste coating method is only to add water-blocking cable paste into the cable paste box, and rely on the gravity of the water-blocking cable paste to coat on the surface of the optical cable. The water-blocking cable paste itself has strong adhesion, but when the optical cable passes quickly, a smooth channel will be formed inside the water-blocking cable paste, which will not be able to automatically and uniformly coat for a long time. In addition, in winter, the water-blocking cable paste will freeze, which makes it more difficult to coat. In addition, the water-blocking cable paste packaging container is generally a 200L cylindrical oil paste barrel. In actual production, the operator needs to continuously transfer the water-blocking cable paste in the oil paste barrel to the cable paste box with a shovel, which not only is not conducive to the cleaning of the working environment, but also increases the labor intensity of the workers, resulting in high labor cost and production cost.

[0033] The following is a preferred embodiment for illustrating the present application, but is not used to limit the scope of the present application.

[0034] Embodiment 1:

[0035] Referring to Figures 1 to 6 As shown in the legends therein, a water-blocking cable paste coating device for an optical cable core comprises:

[0036] A coating mechanism for coating water-blocking cable paste on the optical cable core 1, the coating mechanism comprising a first rack 21, a mounting rack 22 connected to the first rack 21, and a coating and scraping module connected to the mounting rack 22, the coating and scraping module comprising a coating assembly 23, a first scraping assembly 24, a second scraping assembly 25, and a feeding pump 26, the coating assembly 23 being provided with a lumen, the lumen being provided with a feeding port 231 and an overflow port 232 on the side wall, the first scraping assembly 24 being provided with a first scraping hole 241, and the second scraping assembly 25 being provided with a second scraping hole 251, the first scraping hole 241 and the second scraping hole 251 being respectively arranged at the two axial ends of the lumen, and the first scraping hole 241, the lumen, and the second scraping hole 251 forming a coating and scraping channel, and the feeding pump 26 being in communication with the feeding port 231.

[0037] A water-blocking cable paste barrel 3 for containing water-blocking cable paste and providing water-blocking cable paste for the feeding pump 26.

[0038] A guiding mechanism for guiding the optical cable core 1 to move in the horizontal direction and sequentially pass through the first scraping hole 241, the lumen, and the second scraping hole 251.

[0039] In operation, the OPGW optical cable core passes through the cable entry guide wheel, then passes through the coating and scraping module, and then passes through the cable exit guide wheel. In the process of moving forward, the water-blocking cable paste is continuously coated on the cable core, and the excess water-blocking cable paste flows back to the water-blocking cable paste barrel through scraping. The coating and scraping module is used to ensure that a layer of water-blocking cable paste is uniformly coated on the optical cable core 1, so as to isolate the optical fiber jacket from external erosion sources. The outlet of the feeding pump is hard connected to the feeding port through a steel pipe. When the feeding pump works, the water-blocking cable paste is injected into the coating tube. The overflow port is a pressure relief port to prevent the pressure in the coating tube from being too high after the coating tube is filled with water-blocking cable paste. The coating tube, the feeding pump, the first scraping plate, and the second scraping plate are provided. The feeding pump keeps the water-blocking cable paste in the coating tube flowing, and the first scraping plate and the second scraping plate uniformly coat the water-blocking cable paste on the optical cable core.

[0040] In the preferred embodiment of the present application, the water-blocking cable paste barrel 3 has an upward barrel mouth, and the coating and wiping module is arranged directly above the barrel mouth. The water-blocking cable paste barrel 3 receives the water-blocking cable paste flowing from the overflow port 232 and the water-blocking cable paste wiped off by the first wiping assembly 24 and the second wiping assembly 25.

[0041] In the preferred embodiment of the present application, the coating mechanism further comprises a lifting module 27 for lifting the mounting frame. The lifting module 27 is mounted on the first rack 21. Specifically, the lifting module 27 comprises a vertical guide rail 271 for guiding the lifting of the mounting frame 22 and a lifting driving device 272 for lifting the mounting frame 22. Both the vertical guide rail 271 and the lifting driving device 272 are mounted on the first rack 21. The lifting of the mounting frame by the vertical guide rail and the lifting driving device enables the on-line replacement of the water-blocking cable paste barrel. Specifically, the lifting driving device 272 is a pneumatic cylinder.

[0042] In the preferred embodiment of the present application, when the lifting module 27 lifts the mounting frame 22, the coating and wiping module goes up and allows the optical cable core 1 to leave the coating and wiping channel and go below the coating and wiping module. When the lifting module 27 lowers the mounting frame 22, the coating and wiping module goes down and allows the optical cable core 1 below the coating and wiping module to enter the coating and wiping channel.

[0043] In the preferred embodiment of the present application, the coating assembly 23 comprises a first arc-shaped pipe wall 233, a second arc-shaped pipe wall 234, and a quick-mounting clamp 235. The first arc-shaped pipe wall 233 and the second arc-shaped pipe wall 234 are vertically opposite to each other to form the pipe cavity. The two arc-shaped clamping arms of the quick-mounting clamp 235 are fixedly connected to the first arc-shaped pipe wall 233 and the second arc-shaped pipe wall 234, respectively. When the lifting module 27 lifts the mounting frame 22, the two arc-shaped clamping arms of the quick-mounting clamp 235 are opened. When the two arc-shaped clamping arms of the quick-mounting clamp 235 are opened, the second arc-shaped pipe wall 234 rotates away from below the first arc-shaped pipe wall 233, so that the optical cable core can go up and down. The first arc-shaped pipe wall is fixed to the feeding pump.

[0044] In the preferred embodiment of the present embodiment, the first light scraping assembly 24 includes a first light scraping seat 242 and a first light scraping plate 243, and the second light scraping assembly 25 includes a second light scraping seat 252 and a second light scraping plate 253. The first light scraping seat 242 and the second light scraping seat 252 are connected to the mounting frame 22, and the first light scraping seat 242 and the second light scraping seat 252 are respectively provided with a first avoiding hole and a second avoiding hole. The first light scraping plate 243 and the second light scraping plate 253 are respectively installed on the first light scraping seat 242 and the second light scraping seat 252. The first light scraping hole 241 and the second light scraping hole 251 are respectively provided on the first light scraping plate 243 and the second light scraping plate 253. The first avoiding hole, the second avoiding hole, the first light scraping hole 241 and the second light scraping hole 251 are all C-shaped holes with openings downward.

[0045] The lateral openings of the first avoiding hole and the second avoiding hole are relatively large, and the lateral openings of the first light scraping hole and the second light scraping hole are relatively small, that is, the lateral openings of the first light scraping hole and the second light scraping hole match the radial size of the cable core. It does not need to be too large. The first light scraping seat, the second light scraping seat, the first light scraping plate and the second light scraping plate are all cowhide light scraping plates made of polyurethane material, and the center is provided with a wire passing hole with a diameter slightly larger than the diameter of the cable core, so that the excess water-blocking cable paste can be scraped off when the cable core passes through and the cable core surface is not easily scratched. The bottom of the first light scraping seat and the second light scraping seat is cut by wire cutting to the center hole, so that the light scraping plate can be quickly inserted and taken out. The first light scraping plate prevents the excess water-blocking cable paste on the cable core from falling to the ground when the cable core is retracted due to tension when the cable core segment is cut. The second light scraping plate ensures uniform coating of the water-blocking cable paste. The bottom of the first light scraping plate and the second light scraping plate is provided with a notch. Specifically, the cable core 1 passing through the lumen is projected downward on the bottom generatrix of the lumen, the cable core 1 passing through the first light scraping hole is projected downward on the bottom generatrix of the first light scraping hole, and the cable core 1 passing through the second light scraping hole is projected downward on the bottom generatrix of the second light scraping hole. The first light scraping plate 243 is cut along the bottom generatrix of the first light scraping hole to form a first cut, and the second light scraping plate 253 is cut along the bottom generatrix of the second light scraping hole to form a second cut.

[0046] When the lifting module 27 drives the mounting frame 22 to ascend, the quick mounting clamp is opened, the coating and scraping module ascends and allows the cable core 1 to leave the coating and scraping channel to the lower side of the coating and scraping module, when the lifting module 27 drives the mounting frame 22 to descend, the quick mounting clamp is opened, the coating and scraping module descends and allows the cable core 1 at the lower side of the coating and scraping module to enter the coating and scraping channel. When the feeding pump sends the water-blocking cable paste into the lumen, the quick mounting clamp is locked.

[0047] In the preferred embodiment of the present embodiment, the second scraping assembly 25 comprises two second scraping plates 253. The second scraping plates are designed with double scraping, the first scraping is rough scraping and the second scraping is fine scraping, so as to ensure uniform coating of the water-blocking cable paste.

[0048] In the preferred embodiment of the present embodiment, one end of the lumen towards the first scraping plate 243 is a horn mouth. The front end of the coating tube is in the shape of a horn mouth, which facilitates the joint between the completed cable core and the next long cable core to pass through. It is ensured that the joint will not be caught by the coating tube to cause damage to the optical cable.

[0049] In the preferred embodiment of the present embodiment, the coating mechanism further comprises a first heating module 28 for heating the feeding pump 26, a second heating module 29 for heating the water-blocking cable paste in the water-blocking cable paste barrel 3, and a heat preservation module 210 for heating and preserving the temperature of the water-blocking cable paste barrel 3. The first heating module 28 and the second heating module 29 are installed on the mounting frame 22, and the heat preservation module 210 is installed on the outer side wall of the water-blocking cable paste barrel 3. The first heating module 28 is a spiral heating pipe disc installed on the pneumatic plunger pump. Through electrical time delay control, it is ensured that the water-blocking cable paste in the pump pipe is quickly thawed when it is frozen, so as to ensure the normal start and operation of the pneumatic plunger pump. The second heating module 29 comprises a temperature measuring thermocouple 291 and a U-shaped heating pipe 292. Through a temperature control system, the water-blocking cable paste in the 200L water-blocking cable paste barrel 3 is heated, thawed and preserved, so as to ensure the fluidity of the water-blocking cable paste in the barrel. The heat preservation module 210 is used for heating the 200L water-blocking cable paste barrel 3 from the outside to the inside, so as to assist in the heat preservation of the water-blocking cable paste, thereby ensuring the fluidity of the water-blocking cable paste. The heat preservation module 210 is composed of three industrial electric heating blankets, which are independent of each other and controlled by an external temperature controller. The electric heating blankets are installed around the barrel in one circle, and are tightly attached to the barrel body by spring buckles for heat transmission, and can be quickly installed and disassembled.
