[0030] See also Figure 1-3 As shown, the present invention is a cooling device for optical cable production, which includes a cooling component for air cooling and water cooling of the optical cable 1a, and a drying component for drying the outer surface of the optical cable 1a; when in use, the cooling component is first used to cool the optical cable 1a, and then the drying component is used to dry the outer surface of the optical cable 1a; and the cooling component and the drying component are arranged along the conveying direction of the optical cable 1a.

[0031] In order to facilitate cooling of the optical cable 1a and improve the cooling effect of the optical cable 1a, the cooling assembly provided by the present invention includes six cooling mechanisms 1 arranged in series, such as Figure 4-5 The cooling mechanism 1 includes a first water tank 10, and a second water tank 12 is supported on the bottom side of the first water tank 10 by a column 11; slots 121 are provided on the tops of the opposite side walls of the second water tank 12, and a blocking block 13 is provided in the slot 121, and the blocking block 13 and the slot 121 cooperate to form a channel for the optical cable 1a to pass through; the bottom side of the channel is higher than the top surface of the first water tank 10; a blower 3 is provided just above the lead-out end of the optical cable 1a located in the second water tank 12, and the blower 3 The blown airflow is directly facing the optical cable 1a; thereby achieving the above, the optical cable 1a is passed through the second water tank 12, and the cooling water stored in the second water tank 12 is used to water-cool the optical cable 1a, and at the same time, the optical cable 1a is air-cooled by the provided blower fan 3, and then through the above-mentioned arrangement, when in use, air cooling and water cooling are alternately combined, which not only improves the cooling effect of the optical cable, but also avoids the problem of excessive shrinkage of the plastic outer skin of the optical cable due to rapid cooling by water cooling, resulting in more gaps inside.

[0032] Specifically, when in use, a large number of water droplets will adhere to the outer wall of the optical cable 1a passing through the second water trough 12. In order to prevent the water droplets from falling to the ground along with the optical cable 1a, a wiping structure for wiping the water droplets adhered to the outer wall of the optical cable 1a is provided on the outer wall of the second water trough 12 located at the lead-out end of the optical cable 1a; the wiping structure includes fixed rods 14 arranged on both sides of the slot 121, and a wiping member A15 is provided on opposite sides of the two fixed rods 14; the wiping member A15 includes a telescopic cylinder 1701, a base plate 1702 is fixed to the end of the telescopic cylinder 1701, and a sponge block 1703 is provided on one side of the base plate 1702, so that the sponge block 1703 is used to wipe the water droplets adhered to the outer peripheral side of the optical cable 1a when in use.

[0033] It can be known that during long-term use, when the sponge block 1703 of the wiping member A15 absorbs excessive moisture, the sponge block 1703 loses the function of wiping the water drops on the outer peripheral side of the optical cable 1a. Therefore, the wiping structure provided by the present invention also includes an L-shaped frame 16 arranged on an outer side wall of the second water tank 12, and a rotating motor 161 is installed at the top of the L-shaped frame 16. A swing rod 162 is fixed at the end of the rotating motor 161, and a rotating rod 162 is respectively provided at both ends of the swing rod 162. A shaft 163 is provided with a connecting block 164 which can be rotatably mounted on the rotating shaft 163, and an end of the connecting block 164 is connected to a U-shaped frame A17 or a U-shaped frame B18; a wiping member B171 is respectively provided on the two opposite inner walls of the U-shaped frame A17, and a wiping member C81 is respectively provided on the two opposite inner walls of the U-shaped frame B18; the wiping member A15, the wiping member B171 and the wiping member C81 have the same structure; and a controller is also included, which is connected to the rotating motor 161 and the telescopic cylinder 1701.

[0034] Based on the above, when using, it is necessary to control the wiping piece A15, the wiping piece B171 and the wiping piece C81 to be used alternately to wipe the water drops attached to the outer peripheral side of the optical cable 1a.

[0035] Specifically, when in operation, the wiping piece B171 is used to wipe the water drops attached to the outer peripheral side of the optical cable 1a. After 2 minutes, the wiping piece A15 is controlled to wipe the water drops attached to the outer peripheral side of the optical cable 1a, and then the rotating motor 161 is controlled to drive the swing rod 162. At this time, the wiping piece B171 and the wiping piece C81 are controlled to switch functions. At this time, the two telescopic cylinders 1701 in the wiping piece C81 are extended, and the sponge block 1703 in the wiping piece C81 is controlled to wipe the water drops attached to the outer peripheral side of the optical cable 1a; at the same time, the two telescopic cylinders 1701 in the wiping piece B171 are controlled to continue to extend. At this time, the wiping piece B171 is controlled to be wiped. The sponge block 1703 is squeezed to squeeze out the absorbed moisture; while the wiping piece C81 is used to wipe the water droplets attached to the outer peripheral side of the optical cable 1a, the telescopic cylinder 1701 in the wiping piece A15 is controlled to contract, thereby driving the two sponge blocks 1703 in the wiping piece A15 to detach from the outer peripheral side of the optical cable 1a; and then the blower fan 3 is used to air-dry the sponge block 1703 in the non-wiping state when in use; and after switching, the sponge block 1703 in the non-wiping state is located below the optical cable 1a, thereby preventing the moisture squeezed out by the sponge block 1703 controlled by the wiping piece B171 or the wiping piece C81 from dripping onto the outer wall of the optical cable 1a when in use.

[0036] Based on the above, in order to prevent water droplets from falling to the ground along with the optical cable 1a, the present invention can also connect a tube body 19 for the optical cable 1a to pass through between two adjacent first water troughs 10, and both ends of the tube body 19 protrude from the inner wall of the first water trough 10, and the tube body 19 is used to replace the wiping structure.

[0037] It should be noted that the drying assembly provided in the present invention includes a first drying mechanism 4, a second drying mechanism 5 and a third drying mechanism 6 which are arranged in sequence along the pulling direction of the optical cable 1a, and the first drying mechanism 4, the second drying mechanism 5 and the third drying mechanism 6 are all arranged at the end of the cooling mechanism 1 at the very end.

[0038] Specifically, the first drying mechanism 4 includes a ring body A, and the inner wall of the ring body A is provided with a plurality of air intake ports; the second drying mechanism 5 includes a ring body B, and the inner wall of the ring body B is provided with a sponge ring; the third drying mechanism 6 includes a ring body C, and the inner wall of the ring body C is provided with a plurality of exhaust ports; thereby, when in use, the air intake port of the first drying mechanism 4 is used to form a negative pressure to draw away the water droplets adsorbed on the outer wall of the optical cable 1a; the sponge ring is then used to wipe the water droplets that have not been wiped off and evenly distribute them on the outer wall of the optical cable 1a to form a water film; finally, the water film is dried by the air flow blown out of the exhaust port.

[0039] During use, in order to prevent the plastic skin from shrinking too quickly due to the large temperature difference between the water temperature and the plastic skin during water cooling, thereby forming a large number of holes inside the plastic skin, the water temperature in the six second water tanks 12 of the cooling assembly is controlled to gradually decrease along the conveying direction of the optical cable 1a.

[0040] During use, when the room temperature is 25°C, the water temperatures in the six along the second water tank 12 can be controlled to be 70°C, 55°C, 45°C, 38°C, 30°C and 25°C respectively; when the room temperature is 35°C, the water temperatures in the six along the second water tank 12 can be controlled to be 50°C, 48°C, 44°C, 40°C, 38°C and 36°C respectively.

[0041] What you need to know is that Figure 6 In order to circulate the cooling water in the second water tank 12 during use, a return water tank 7 is connected to the bottom side of the first water tank 10, and a return water pipe 90 is arranged above any second water tank 12; the top of the return water pipe 90 is connected to the cooling component 9, and a water pump 8 for pumping water to the top of the cooling component 9 is arranged in the return water tank 7. When the cooling water in the second water tank 12 is discharged into the first water tank 10 through the slot 121 during use, it is collected by the return water tank 7 and then transported back to the second water tank 12 for circulation by the cooperation of the water pump 8 and the cooling component 9.

[0042] In order to facilitate the control of the liquid level and water temperature in the second water tank 12, the liquid level sensor and the temperature sensor in the second water tank 12 are connected to the controller; Figure 7-8 The cooling assembly 9 provided by the present invention includes a cylinder 91 located at the bottom, and a water inlet pipe 95 connected to the water pump 8 is arranged on one side of the cylinder 91; a plurality of openings 911 are arranged on the bottom side of the cylinder 91, and a cooling pipe 92 is connected to the outer side of the cylinder 91 located at the openings 911, and the plurality of cooling pipes 92 are all connected to a manifold 93, and the manifold 93 is connected to the return pipe 90 through a pipeline; a top plate 94 with a plurality of openings 941 is arranged on the top of the cylinder 91, and a bottom side of the top plate 94 is connected to a cooling pipe 92 along the inner side of the cylinder 91 through a telescopic motor 95.
