[0036] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0037] Reference Figure 3 A high-speed armored optical cable production system is suitable for a high-speed production line of armored optical cables with a production speed of not less than 150m / min. The high-speed armored optical cable production system includes a multi-stage water bead removal system and a metal strip forming mold water cooling system. The multi-stage water bead removal system is used to remove water droplets from the optical cable body after the sheath is cooled; the water droplets are collected in a water storage tank and added to the circulating cooling water used by the metal strip forming mold water cooling system through a return pipe.

[0038] Reference Figures 4 to 11, the multi-stage water bead removing system comprises a brush, a ring-shaped air knife and a hot air dryer 15 arranged in sequence along the advancing direction of the armored optical cable 1100, the brush, the ring-shaped air knife and the hot air dryer 15 are respectively the first stage, the second stage and the third stage water bead removing structure 1300, the cooling water tank 1200 is filled with cooling water 1201 for cooling the armored optical cable 1100, the cooled armored optical cable 1100 comes out from the side plate 1202 of the cooling water tank 1200, the brush is used for brushing off the water beads 1300 on the outer surface of the armored optical cable 1100 coming out from the cooling water tank 1200, the ring-shaped air knife has a plurality of circumferentially arranged air slits 17 for blowing off the water beads 1300 adhered to the outer surface of the armored optical cable 1100 and for thinning the water marks on the cable surface, and the hot air dryer 15 is used for blowing hot air to dry the outer surface of the armored optical cable 1100. Through the three-stage water bead removing structure 1300, the first-stage brush can sweep off the large-particle water beads 1300 on the surface of the armored optical cable 1100, the second-stage ring-shaped air knife can blow off the small-particle water beads 1300 on the surface of the armored optical cable 1100, and the third-stage hot air dryer 15 removes the tiny-particle water beads 1300 on the surface of the armored optical cable 1100 by drying, thereby eliminating the false alarm of electric spark breakdown caused by the residual water beads 1300 on the surface of the armored optical cable 1100, eliminating the false alarm of bulging caused by the residual water beads 1300 on the surface of the armored optical cable 1100, and preventing the negative impact on the quality of code spraying and marking. The bristles on the brush are made of soft hair to avoid scratching the outer surface of the armored optical cable 1100. The use of the brush instead of water-absorbing materials can effectively collect large-particle water beads without causing drying effect attenuation due to water absorption saturation. The first-stage water bead removing system uses the brush to continuously and efficiently collect a large amount of water beads brought out by the cable, which can effectively dry the cable on one hand and effectively save water as mold cooling water on the other hand.

[0039] Further, the brush has a plurality of brushes, including a first brush 11 and a second brush 12 arranged in sequence along the advancing direction of the armored optical cable 1100, the bristles of the first brush 11 are horizontally arranged, and the bristles of the second brush 12 are vertically arranged. The distance between the outlet of the cooling water 1201 tank baffle and the ring-shaped air knife is L, the brush can make the large water beads 1300 on the surface of the armored optical cable 1100 flow downward due to gravity, and the two kinds of brushes are used to contact the armored optical cable 1100 and are arranged between the cooling water 1201 tank baffle and the compressed air dryer to sweep off the large-particle water beads on the surface of the armored optical cable 1100. When the armored optical cable 1100 passes through the second brush 12, the large-particle water beads are swept off, and the remaining water beads on the bottom of the armored optical cable 1100 are visible to the naked eye, and the second brush 12 is arranged again to sweep off the remaining water beads again.

[0040] Further, the annular air knives are multiple to cooperate with the 360° blowing of the water drops 1300 on the whole circumference of the outer surface of the armored optical cable 1100. The annular air knives are preferably provided with two.

[0041] After the first-stage brush removes the large water drops on the surface of the armored optical cable 1100, small water drops are left on the surface of the armored optical cable 1100. Then, the annular air knives forcibly blow away the small water drops. The annular air knives are two in total. The first annular air knife blows away most of the small water drops on the left and right sides of the armored optical cable 1100, and the second air slit 17 blows away the small water drops on the longitudinal blind area of the first air slit. In addition, the air knife can effectively thin the water marks and improve the hot air drying efficiency.

[0042] Further, the air outlet direction of each air slit 17 of the annular air knife is opposite to the advancing direction of the armored optical cable 1100. The air outlet direction of each air slit 17 of the annular air knife forms an angle greater than 0° and less than 90° with the axial direction of the armored optical cable 1100, that is, the air outlet direction is neither perpendicular nor parallel to the axial direction. The air outlet direction forms a resistance to the advancement of the armored optical cable 1100, which can play a role in removing water drops and thinning water marks.

[0043] When the first annular air knife 13 close to the brush is installed in a transverse layout, the air slit 17 direction of the first annular air knife 13 forms an angle a with the axial direction of the armored optical cable 1100. The perpendicular component of the force F*sina perpendicular to the direction of the armored optical cable 1100 is used to squeeze the water drops close to the surface of the armored optical cable 1100, which plays a role in removing water drops and making them separate from the armored optical cable 1100. The parallel component of the force F*cosa parallel to the armored optical cable 1100 pushes the water drops 1300 in the opposite direction. When the water drops 1300 are accumulated to a certain height, the perpendicular component blows the water drops 1300 away from the armored optical cable 1100. When a is 45°, the perpendicular component is equal to the parallel component. Generally, when a is between 45° and 60°, the blowing drying effect is better. The first annular air knife 13 is installed on the bracket 18. The blowing blind area 16 appears on the left and right installation positions of the first annular air knife 13. A second annular air knife 14 needs to be arranged next. The second annular air knife 14 is turned by a certain angle in the circumferential direction to avoid the projection of the blowing blind area 16 of the second annular air knife 14 overlapping the blowing blind area 16 of the first annular air knife 13. The air slit 17 of the second annular air knife 14 blows away the water drops 1300 on the left and right sides of the armored optical cable 1100, which removes the water drops 1300 in the area that cannot be blown by the blowing blind area 16 of the first annular air knife 13.

[0044] The third level hot air dryer 15 is to heat the compressed air and blow it out to dry the fine water molecules on the surface of the armored optical cable 1100, so as to avoid false alarm of power frequency spark. The hot air dryer 15 generates hot air, and the temperature of the hot air is generally between 90-110℃. The hot air dryer 15 includes a hot air blower 151 and an air outlet cylinder 152. The hot air blower 151 blows hot air to the air outlet flow channel of the air outlet cylinder 152. The side wall of the air outlet cylinder 152 is provided with air outlet holes 1521 which are in communication with the air outlet flow channel. In this way, the armored optical cable 1100 entering the air outlet cylinder 152 can be continuously dried. A plurality of groups of air outlet holes are arranged along the axial direction of the air outlet cylinder 152. Each group of air outlet holes includes a plurality of circumferentially uniformly arranged air outlet holes 1521. The length L1 of the range continuously acts on the surface of the armored optical cable 1100, and the fine water droplets on the surface of the armored optical cable 1100 which cannot be directly identified by the naked eye are dried.

[0045] The water storage tank 300 is used to collect the water droplets brushed off by the brush. The water storage tank 300 is connected to the circulating water tank of the water cooler main body 21 through the water return pipe 301 and the water pump, and then performs water cooling circulation through the circulating water tank. The water return pipe 301 is provided with a filter 302 to filter impurities in the water.

[0046] The metal strip forming die water cooling system includes a water cooler main body 21, a first water cooling assembly, a second water cooling assembly and a third water cooling assembly.

[0047] The first water cooling assembly includes a first water inlet pipe 22, a first water cooling sleeve 23 and a first water outlet pipe 24. The first cold water outlet 211 of the water cooler main body 21 is connected to the first water inlet pipe 22 to deliver cold water to the first water inlet pipe 22. The first water cooling sleeve 23 is provided with a first cooling water flow channel. The inlet and outlet of the first cooling water flow channel are connected to the first water inlet pipe 22 and the first water outlet pipe 24, respectively. After the first water cooling sleeve 23 is water cooled by the cooling water flow channel, hot water is discharged through the first water outlet pipe 24. The first water cooling sleeve 23 has a first inner hole for sleeving a sizing die to cool the sizing die, so that the temperature of the sizing die is lower than the peeling-off temperature of the surface film layer of the metal strip. The sizing die is used to form a closed metal strip into a cylindrical pipe.

[0048] The second water cooling assembly comprises a second water inlet pipe 25, a second water cooling sleeve 26 and a second water outlet pipe 27, the second water inlet pipe 25 and the second water outlet pipe 27 are connected to the second cold water outlet 212 and the first hot water inlet 213 of the water cooling machine body 21 respectively, the second water inlet pipe 25 transports the cold water into the water cooling machine body 21, the second water outlet pipe 27 discharges the hot water into the water cooling machine body 21 for cooling again to form circulating water. The second water cooling sleeve 26 is provided with a second cooling water flow channel, the inlet and outlet of the second cooling water flow channel are connected to the second water inlet pipe 25 and the second water outlet pipe 27 respectively, the first water cooling sleeve 23 has a second inner hole for sleeving a compression mold for cooling the compression mold so that the temperature of the compression mold is lower than the peeling-off temperature of the surface film layer of the metal strip.

[0049] The third water cooling assembly comprises a third water cooling sleeve 28 and a third water outlet pipe 29, the second hot water inlet 214 of the water cooling machine body 21 is connected to the third water outlet pipe 29, the hot water discharged by the third water outlet pipe 29 flows back to the water cooling machine body 21 through the second hot water inlet 214. The third water cooling sleeve 28 is provided with a third cooling water flow channel, the inlet and outlet of the third cooling water flow channel are connected to the first water outlet pipe 24 and the third water outlet pipe 29 respectively, the water discharged by the first water outlet pipe 24 is used to cool the third water cooling sleeve 28. The third water cooling sleeve 28 has a third inner hole for sleeving a preforming mold for cooling the preforming mold so that the temperature of the preforming mold is lower than the peeling-off temperature of the surface film layer of the metal strip.

[0050] The preforming block, the preforming mold, the compression mold and the sizing die are used to shape the metal strip respectively, which belongs to the prior art and will not be described here.

[0051] The first water cooling sleeve 23, the second water cooling sleeve 26 and the third water cooling sleeve 28 are coaxially arranged, the controller of the water cooling machine body 21 can set and adjust the water temperature, and the water tank of the water cooling machine body 21 is provided with a water level sensor to alarm when the water level is insufficient.

[0052] If the water cooling system of the application is not arranged outside the mold, the temperatures of the preforming mold, the compression mold and the sizing die are t2, t3 and t4 respectively in the existing conventional shaping, the application adjusts the temperatures of the preforming mold, the compression mold and the sizing die for shaping the metal strip, efficiently reduces the temperatures of the preforming mold, the compression mold and the sizing die through water cooling circulation, prevents the peeling-off of the double-sided plastic film layer of the metal strip, and prevents the faults of belt breakage, spark breakdown and bulging.

[0053] The three molds of the preforming mold, the pressing mold and the sizing mold are installed in corresponding water-cooled mold sleeves. When the metal strip and the cable core are fed into the preforming mold, the pressing mold and the sizing mold at high speed, the heat generated by the friction between the metal strip and the mold is exchanged by the cold water injected into the cavities of the water-cooled mold sleeves. The heated water is recycled into the water-cooled machine main body 21 through the pipeline, and is converted into cold water in the water-cooled machine main body 21, and then is injected into the water-cooled mold sleeves through the pipeline.

[0054] The temperature of the pressing mold is relatively high, and a single water-cooled circulation is used.

[0055] Since the temperature of the sizing mold and the preforming mold is lower than that of the pressing mold, a single water-cooled circulation can be shared. The cold water is first connected to the inlet of the first water-cooled mold sleeve 23 through the first water inlet pipe 22. The warm water at the outlet of the first water-cooled mold sleeve 23 is connected to the inlet of the third water-cooled mold sleeve 28 through the first water outlet pipe 24. The water at the outlet of the third water-cooled mold sleeve 28 is recycled into the water-cooled machine through the third water outlet pipe 29. After cooling, the above circulation is repeated.

[0056] The inlet pipeline of the water inlet pipe is connected to the cold water outlet of the refrigeration machine, and the outlet of the water outlet pipe is connected to the recycling port of the refrigeration machine. In addition to the common refrigeration function, the refrigeration machine also has the functions of water temperature setting and adjusting, and water tank water level alarm, so as to achieve the desired cooling process temperature of the forming mold.

[0057] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present application, and is not used to limit the present application.
