Description

Technical Field

[0001] The present invention relates to the technical field of optical cable production, and in particular to an optical cable cooling device and optical cable production equipment. 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 external plastic sheath is generated by an extruder. When the optical cable is sent out from the extruder, the plastic sheath is in a high temperature state and needs to be cooled.

[0003] In traditional optical cable production lines, a cooling device for cooling optical cables is usually provided, which is mainly a cooling tank with circulating cooling water. The high-temperature optical cable sent from the extruder passes through the cooling tank and contacts and exchanges heat with the cooling water in the tank, thereby achieving the purpose of water cooling of the high-temperature optical cable.

[0004] In the related art, after the high-temperature optical cable enters the cooling tank of the traditional cooling device, its horizontal position usually remains unchanged, and then the cooling water is driven to flow horizontally to achieve the heat exchange and cooling effect. This makes the cooling water temperature near the bottom of the cooling tank in the longitudinal direction always lower than the water temperature near the open part of the cooling tank. When the cooling water circulates, the cooling water near the bottom of the cooling tank flows out of the cooling tank before it can fully exchange heat. The heat exchange rate of the optical cable cooling device is low, the heat exchange effect is limited, and the cooling effect is poor; moreover, it causes a large waste of cooling energy and high energy consumption.

The cooling surface of the semiconductor refrigeration sheet is in contact with the outer wall of the cooling tank, and the heat sink is in contact with the heat dissipation surface of the semiconductor refrigeration sheet. A plurality of heat dissipation fins are installed on the heat sink.

[0013] In a possible implementation manner, the optical cable cooling device further comprises a heat transfer cover, which is arranged outside the cooling groove and forms a heat transfer channel between the heat transfer cover and the cooling groove;

[0017] In a possible embodiment, the optical cable cooling device also includes an extrusion plate and a connecting rope. The extrusion plate is movably installed in the shell along the thickness direction of the cooling groove and is located below the adsorption cotton. A plurality of drainage holes are opened on the extrusion plate. The two ends of the connecting rope are respectively connected to the adjusting rod and the extrusion plate.

[0018] In a possible implementation manner, the water absorption mechanism is installed at a position of the cooling trough close to an outlet of the optical cable.

[0019] In a possible implementation manner, the optical cable cooling device further includes a plurality of guide pulleys spaced apart along the direction of the optical cable, and the guide pulleys are used for slidingly connecting the optical cable.

[0020] In a second aspect, the present application provides an optical cable production device, comprising the optical cable cooling device as described in any one of the first aspects.

[0021] Beneficial effects of this application:

[0022] 1. Through the technical solution of the present application, part of the optical cable entering the cooling tank can move up and down in the cooling tank, so that the high-temperature optical cable can be in contact with the cooling water at different longitudinal heights as much as possible, so that the high-temperature optical cable can fully exchange heat with the cooling water, thereby improving the heat exchange rate and heat exchange effect of the device, improving the cooling effect, and reducing the loss of cold energy.

[0023] 2. Through the technical solution of the present application, the cooling water in the cooling trough is in a relatively static state. By moving the high-temperature optical cable up and down, it can achieve full contact with the cooling water at different longitudinal heights, thereby improving the heat exchange effect between the high-temperature optical cable and the cooling water, further improving the cold energy utilization rate of the device, and reducing energy consumption.

[0024] 3. Through the technical solution of the present application, the reciprocating screw can also drive the fan blades to rotate at the same time. When the fan blades rotate, not only the cooling water in the cooling tank can be air-cooled, but also the heat sink on the heat exchanger can be air-cooled, thereby improving the cooling effect of the cooling water. In addition, the heat emitted by the cooling water and the heat emitted by the heat sink can be brought into the drying channel to dry the wet optical cable, thereby improving the energy utilization rate of the device.

[0025] 4. Through the technical solution of the present application, when the lifting frame moves downward and drives part of the optical cable in the cooling trough to move downward, the length of the optical cable in the cooling trough increases, and the optical cable at the adjustment mechanism will contact the tensioning wheel, causing the adjustment rod to move upward, thereby shortening the length of the optical cable at the adjustment mechanism, thereby supplementing the length of the optical cable in the cooling trough. When the lifting frame moves upward and drives part of the optical cable in the cooling trough to move upward, the length of the optical cable in the cooling trough shortens, and the optical cable at the adjustment mechanism becomes loose. At this time, the adjustment rod moves downward due to the downward gravity of the counterweight, thereby lengthening the length of the optical cable at the adjustment mechanism. The length of the optical cable is adaptively adjusted by the adjustment mechanism to ensure that the production process of the optical cable will not be affected.

[0026] 5. Through the technical solution of the present application, when the optical cable passes through the adsorbent cotton, the water droplets attached to the surface of the optical cable can be adsorbed, so that when the subsequent optical cable passes through the drying channel, the drying effect of the optical cable can be further improved.

[0027] 6. Through the technical solution of the present application, when the adjusting rod moves to the end of the stroke, the extrusion plate can be driven to move upward through the connecting rope to perform an extrusion operation on the adsorbent cotton, thereby squeezing out the moisture in the adsorbent cotton, thereby ensuring that the moisture content of the adsorbent cotton remains in a relatively low state, so that the adsorbent cotton can effectively absorb water droplets on the optical cable.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] like Figure 1-Figure 4 As shown, an embodiment of the present application provides an optical cable cooling device, which includes a cooling tank 100, a lifting frame 200, and a driving mechanism. The top side of the cooling tank 100 is open, and an optical cable inlet 110 and an optical cable outlet 120 are respectively arranged on both sides of the opening. The optical cable can enter the cooling tank 100 from the optical cable inlet 110, pass through the cooling tank 100, and then leave the cooling tank 100 from the optical cable outlet 120. Guide pulleys for connecting optical cables are respectively installed at the optical cable inlet 110 and the optical cable outlet 120. Cooling water is filled in the cooling tank 100 to cool the optical cable passing through the cooling tank 100.

[0037] The lifting frame 200 is disposed in the cooling tank 100 and at least partially extends into the receiving chamber. The lifting frame 200 is used to press down the corresponding optical cable on the side facing the cooling tank 100 so that the optical cable is located at different positions in the thickness direction of the cooling tank 100. Guide pulleys for connecting the optical cable are respectively installed at both ends of the bottom side of the lifting frame 200. The driving mechanism is used to drive the lifting frame 200 to reciprocate along the thickness direction of the cooling tank 100.

[0038] Through the above technical solution, part of the optical cable entering the cooling tank 100 can continuously move up and down in the cooling tank 100, so that the high-temperature optical cable can be in contact with the cooling water at different longitudinal heights as fully as possible, so that the high-temperature optical cable can fully exchange heat with the cooling water, thereby improving the heat exchange rate and heat exchange effect of the device, improving the cooling effect, and reducing cold energy loss.

[0039] It should be noted that the thickness direction of the cooling groove 100 mentioned in this embodiment is equivalent to the longitudinal direction, and can also be understood as the vertical direction perpendicular to the ground.

[0040] In a possible embodiment, the driving mechanism includes a plurality of guide rods 310, a reciprocating screw 320 and a motor 330. In one example, the number of guide rods 310 is at least two, and the two guide rods 310 are symmetrically distributed on both sides of the reciprocating screw 320 and extend along the thickness direction of the cooling tank 100. One end of the guide rod 310 can be fixedly connected to the bottom of the cooling tank 100 by welding or the like, and the other end can be detachably connected to a connecting beam disposed laterally on the opening of the cooling tank 100 by a threaded structure. The lifting frame 200 is provided with a movable hole, and the lifting frame 200 can be movably sleeved on the guide rod 310 through the movable hole. In this way, the lifting frame 200 can be guided in the thickness direction of the cooling tank 100 by the guide rod 310, thereby improving the movement accuracy and reliability of the lifting frame 200 in this direction, thereby improving the position accuracy of the optical cable in this direction, and realizing the cooling and temperature reduction of the optical cable at different levels. One end of the reciprocating screw 320 can be rotatably mounted on the bottom of the cooling trough 100 through a bearing or other structure, and the other end extends along the thickness direction of the cooling trough 100 and extends out of the opening of the cooling trough 100 to be connected to the output end of the motor 330. The motor 330 can be a servo motor or a stepper motor, and the output shaft of the motor 330 can be connected and fixed to the reciprocating screw 320 through a coupling. The lifting frame 200 can be sleeved on the outside of the reciprocating screw 320 through a threaded structure, and at the same time, can be sleeved on the outside of the guide rod 310 through a movable hole. In this way, the reciprocating screw 320 can be driven to rotate by the motor 330 to drive the lifting frame 200 threadedly sleeved on the reciprocating screw 320 to reciprocate along the guide rod 310, so that the optical cable wound around the bottom of the lifting frame 200 reciprocates in the cooling trough 100 along the thickness direction of the cooling trough 100, so as to achieve cooling and cooling of the optical cable at different heights in the longitudinal direction of the cooling trough, with good cooling effect and high effective utilization rate of cold energy.

[0041] In another embodiment, the driving mechanism may also use structures such as an electric cylinder, an electric hoist, etc. to control the up and down movement of the lifting frame 200.

[0042] In a possible embodiment, the material of the cooling tank 100 is preferably a metal material with good thermal conductivity, such as iron, aluminum, etc. A plurality of heat exchangers 130 are installed on the cooling tank 100, mainly the heat exchangers 130 are installed on the front and rear sides of the cooling tank 100, for absorbing the heat of the cooling water, cooling and lowering the temperature of the cooling water.

[0043] The heat exchanger 130 includes a semiconductor refrigeration sheet 131 and a heat sink 132. Among them, the semiconductor refrigeration sheet 131 is a relatively mature traditional technology, having a relatively set cooling surface and a heat sink surface, which will not be described in detail here. The cooling surface of the semiconductor refrigeration sheet 131 can be attached to the outer wall of the cooling tank 100 by welding or silicone grease bonding to cool the cooling water in the cooling tank 100. The heat sink 132 is attached to the heat sink surface of the semiconductor refrigeration sheet 131, and can also be bonded by silicone grease, and a number of evenly arranged heat sink fins are installed on the heat sink 132, each of which is vertically arranged, so as to quickly dissipate the heat of the semiconductor refrigeration sheet 131 and achieve a better cooling effect.

[0044] In this embodiment, the cooling water in the cooling tank 100 is cooled by a heat exchanger 130, which is different from the cooling water circulation method in the conventional technology. The heat exchange method in this embodiment allows the cooling water to be in a relatively static state as much as possible, and the optical cable is moved up and down to make it fully contact with the cooling water at different heights in the longitudinal direction, thereby improving the heat exchange effect between the high-temperature optical cable and the cooling water, further improving the cold energy utilization rate of the device, and reducing energy consumption.

[0045] In a possible embodiment, the optical cable cooling device further includes a heat transfer cover 400, which is disposed on the outside of the cooling groove 100 and fixed to the cooling groove 100. A cover inlet 410 and a cover outlet 420 are also disposed on both sides of the heat transfer cover 400, and the optical cable can enter the heat transfer cover 400 from the cover inlet 410, pass through the cooling groove 100, and then pass out from the cover outlet 420.

[0046] In addition, a heat transfer channel 430 is formed between the heat transfer cover 400 and the cooling tank 100, and the heat exchanger 130 is located in the heat transfer channel 430. A plurality of ventilation holes 440 are provided on the top side of the heat transfer cover 400, and a drying channel 450 is provided on the bottom side. The ventilation holes 440, the heat transfer channel 430 and the drying channel 450 are connected, and the optical cable coming out of the cooling tank 100 can enter the drying channel 450. Guide pulleys for connecting the optical cable are installed on the outside and inside of the heat transfer cover 400 to ensure that the optical cable can enter the drying channel 450. A plurality of fan blades 460 are rotatably installed on the top side of the heat transfer cover 400, and the rotating shafts of the fan blades 460 are drivingly connected to the reciprocating screw 320. Specifically, the reciprocating screw 320 is keyed with a driving gear 321, and the rotating shaft of the fan blade 460 is keyed with a driven gear 461, and the driven gear 461 and the driving gear 321 are meshed with each other to realize the rotation of the fan blade 460. In addition, the motor 330 is also fixed on the top side of the heat transfer cover 400.

[0047] Through the above technical solution, the reciprocating screw 320 can also drive the fan blade 460 to rotate at the same time. When the fan blade 460 rotates, it can not only cool the cooling water in the cooling tank 100, but also cool the heat sink 132 on the heat exchanger 130, thereby improving the cooling effect of the cooling water. In addition, the heat emitted by the cooling water and the heat emitted by the heat sink 132 can be brought into the drying channel 450 to dry the wet optical cable, thereby improving the energy utilization rate of the device.

[0048] Since the lifting frame 200 can drive part of the optical cable to move up and down in the cooling trough 100, this will inevitably cause the length of the optical cable passing through the cooling trough 100 to be in a dynamically changing state, while the speeds of the outlet device and the take-up device at both ends of the optical cable production line are always in a uniform state. The change in the length of the optical cable at the optical cable cooling device process station will cause the optical cable to be pulled, which will affect the normal production process of the optical cable.

[0049] In order to solve the above problems, the optical cable cooling device in this embodiment also includes an adjustment mechanism 500 for adaptively adjusting the length of the optical cable, and the adjustment mechanism 500 includes a mounting frame 510, an adjustment rod 520, a tensioning wheel 530 and a counterweight 540. Among them, the mounting frame 510 is transversely fixed on one side of the heat transfer cover 400 close to the cover body outlet 420. The adjustment rod 520 is movably inserted in the mounting frame 510 and can reciprocate along the thickness direction of the cooling groove 100. The upper end of the adjustment rod 520 is fixed with a limit plate 521 to prevent the adjustment rod 520 from being separated from the mounting frame 510. The tensioning wheel 530 is rotatably mounted on the bottom end of the adjustment rod 520 for winding the optical cable sent out from the cooling groove 100. The counterweight 540 is mounted on the bottom end of the adjustment rod 520. In addition, guide pulleys for connecting the optical cable are also installed on both sides of the adjustment rod 520 on the mounting frame 510, and the horizontal heights of the two sets of guide pulleys are always higher than the horizontal height of the tensioning wheel 530.

[0050] Through the above technical solution, when the lifting frame 200 moves downward and drives part of the optical cable in the cooling tank 100 to move downward, the length of the optical cable in the cooling tank 100 increases, and the optical cable at the adjustment mechanism 500 will contact the tension wheel 530, so that the adjustment rod 520 moves upward, thereby shortening the length of the optical cable at the adjustment mechanism 500, so as to supplement the length of the optical cable in the cooling tank 100. When the lifting frame 200 moves upward and drives part of the optical cable in the cooling tank 100 to move upward, the length of the optical cable in the cooling tank 100 shortens, and the optical cable at the adjustment mechanism 500 becomes loose. At this time, the adjustment rod 520 moves downward under the downward gravity of the counterweight 540, so that the length of the optical cable at the adjustment mechanism 500 becomes longer. The length of the optical cable is adaptively adjusted by the adjustment mechanism 500 to ensure that the production process of the optical cable will not be affected.

[0051] In a possible embodiment, the optical cable coming out of the cooling water may be accompanied by a large number of water droplets, and the degree of drying of the optical cable may not be guaranteed by relying solely on the drying effect of the drying channel 450. Therefore, the optical cable cooling device in this embodiment also includes a water absorption mechanism 600 for removing water droplets on the surface of the optical cable, and the water absorption mechanism 600 includes a shell 610 and an adsorption cotton 620. Among them, the shell 610 can be fixed on the cooling tank 100 or the heat transfer cover 400, and is located on the open side of the cooling tank 100, and the optical cable coming out of the cooling tank 100 can pass through the shell 610. The adsorption cotton 620 is installed in the shell 610, and the optical cable also passes through the adsorption cotton 620. The adsorption cotton 620 is mainly made of sponge. When the optical cable passes through the adsorption cotton 620, the water droplets attached to the surface of the optical cable can be absorbed, so that when the subsequent optical cable passes through the drying channel 450, the drying effect of the optical cable can be further improved.

[0052] In a possible embodiment, the optical cable cooling device further includes an extrusion plate 630 and a connecting rope 640. The extrusion plate 630 is movably installed in the housing 610 along the thickness direction of the cooling trough 100 and is located at the lower side of the adsorbent cotton 620. A plurality of drainage holes 631 are provided on the extrusion plate 630, and the bottom side of the housing 610 is also designed as a hollow structure. One end of the connecting rope 640 is fixed to the adjustment rod 520, and the other end is fixed to the extrusion plate 630. When the adjustment rod 520 moves to the end of the stroke (the uppermost end or the lowermost end), the extrusion plate 630 can be driven to move upward by the connecting rope 640, and the adsorbent cotton 620 is squeezed to squeeze out the moisture in the adsorbent cotton 620, thereby ensuring that the moisture content of the adsorbent cotton 620 is kept at a relatively low state, so that the adsorbent cotton 620 can effectively adsorb the water droplets on the optical cable.

[0053] In addition, the connecting rope 640 can be an elastic rope with a certain elasticity, so that the connecting rope 640 has a buffering force and is not easy to be broken. A guide pulley for receiving the connecting rope 640 can also be installed on the heat transfer cover 400, so that the movement of the connecting rope 640 is more regular.

[0054] In a possible embodiment, the water absorption mechanism 600 is installed in the cooling tank 100 near the optical cable outlet 120. A guide pulley connected to the optical cable is also installed in the cooling tank 100 on the left side of the water absorption mechanism 600. Through this arrangement, the water squeezed out of the absorption cotton 620 can flow back into the cooling tank 100, reducing the loss of cooling water.

[0055] In a possible embodiment, all guide pulleys have the same structure, including a pulley frame and a pulley, and the pulley is rotatably mounted on the pulley frame. The specific number and installation position of the guide pulleys can be changed according to actual conditions, and this embodiment does not make specific limitations.
