Description

Technical Field

[0001] The invention belongs to the technical field of production and processing of electric wires and cables, and specifically relates to a surface cooling device for cable production. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors;

[0003] The production process of general wires and cables generally includes the following steps: drawing copper and aluminum monofilaments; annealing of monofilaments; twisting of conductors; extrusion of insulation; and cabling.

[0004] In the insulation extrusion process of wires and cables, polyethylene and polyvinyl chloride are usually used as insulation layer materials. The plastic insulation of wires and cables is generally made by direct extrusion or vacuum extrusion. The extruded insulation layer should be tightly and evenly wrapped on various conductive cores. The thickness of the extrusion should ensure the plastic thickness specified by the process. The process thickness of the insulation layer should comply with and meet the corresponding national standards for various wires and cables.

[0005] In the insulation extrusion process of the cable, the applicant found that the prior art had the following problems:

[0006] 1. During the cable insulation extrusion process, the surface temperature of the extruded cable is too high and needs to be cooled. However, the prior art usually directly immerses the extruded cable in cold water for rapid cooling. However, due to the temperature difference between the cable surface insulation layer and the cold water, it is very easy to cause the cable insulation layer to crack and generate gap bubbles, which affects the appearance and subsequent use of the cable.

[0007] 2. After the cable is cooled, some moisture will adhere to its surface. If the moisture on the surface of the cable insulation layer is not removed, it will affect the subsequent packaging process of the cable. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a surface cooling device for cable production, which is used to solve the problem in the prior art that, during the cable insulation extrusion process, the surface temperature of the extruded cable is too high and needs to be cooled.

[0040] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. DETAILED DESCRIPTION

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0044] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0045] In one embodiment of the present invention, Figure 1 As shown, a surface cooling device for cable production includes: a support component 1, a cooling component 2, a transmission component 4, a rotating cooling component 27 and a water removal component 28;

[0046] The support assembly 1 includes a bottom plate 13, a pay-off roller 11 and a take-up roller 12 fixed on the bottom plate 14;

[0047] Specifically, the base plate 13 is used to support the cooling component 2, the transmission component 4, the rotating cooling component 27 and the water removal component 28 thereon, and the base plate 13 is also symmetrically fixedly connected with support legs, and a reinforcing plate is fixed between the support legs, and the reinforcing plate is used to enhance the bearing capacity of the support component 1. At the same time, the cable to be cooled is wound around the pay-off roller 11, and the cable after cooling is wound around the take-up roller 12. The pay-off of the pay-off roller 11 to be cooled and the take-up of the take-up roller 12 after cooling are completed by a driving mechanism, wherein the driving mechanism can be an ordinary motor, which is not drawn in detail in the accompanying drawings.

[0048] The cooling assembly 2 is mounted on the bottom plate 13, and includes a box body 21 and a plurality of cooling boxes 24 horizontally and equidistantly distributed in the box body 21. The side walls of the box body 2 close to the pay-off roller 11 and the take-up roller 12 and the two side walls of the cooling box body 24 are respectively provided with a first through hole 22 and a second through hole 23 for the cable to pass through, and the plurality of cooling boxes 24 are correspondingly connected to a liquid storage tank 214 through a water pipe 25;

[0049] It is worth noting that the cable to be cooled first enters the cooling assembly 2 through the first through hole 22. After entering the cooling assembly 2, the cable then passes through the second through hole 23 and passes through a plurality of cooling boxes 24 in sequence to complete the cooling process of the cable. Meanwhile, during the cooling process, the coolant stored in the liquid storage tank 214 enters the cooling box 24 corresponding thereto to complete the cooling process of the cable.

[0050] like Figure 2As shown, at the same time, in the liquid storage tank 214 in this embodiment, a heating element 215 is fixed therein, and the heating element 215 is used to heat the coolant in the liquid storage tank 214 to ensure that a certain temperature difference is formed between the coolants in the liquid storage tanks 214, thereby realizing step-by-step cooling of the cable.

[0051] The transmission component 4 is installed in the box body 21, and the transmission component 4 includes a first transmission roller 41, a second transmission roller 42 and a third transmission roller 43. The first transmission roller 41 and the third transmission roller 43 are installed at a position close to the first through hole 22, and the second transmission roller 42 is installed on the side wall of the box body 21 away from the first through hole 22. The cable passes through the first transmission roller 41, the cooling box body 24, the second transmission roller 42 and the third transmission roller 43 in sequence. The transmission component 4 is used to assist the movement of the cable in the box body 21 to change the transmission direction of the cable in the box body 21, so as to ensure that the cable can be cooled and dried in sequence.

[0052] like Figure 5 , 6 As shown, the rotating cooling component 27 is installed in the cooling box 24, and the rotating cooling component 27 includes an annular support frame 271 fixed in the cooling box 24, a gear ring 272 rotatably installed on the annular support frame 271, and a gear 277 meshed with one side of the gear ring 272. A liquid storage ring 273 is fixed on the inner side of the gear ring 272, and a bellows 279 is connected to one side of the liquid storage ring 273 through a rotating joint 2710. The bellows 279 is fixedly connected to the water pipe 25, and the liquid storage ring 273 is fixedly connected to the water pipe 25. A nozzle 274 is fixed on the inner side of the ring 273 and can rotate along the cable as the axis. An anti-collision cylinder 275 is provided on the side of the liquid storage ring 273 away from the annular support frame 271. A third through hole is reserved on the anti-collision cylinder 275 for the cable to pass through. One end of the anti-collision cylinder 275 extends toward the gear ring 272 until one end of the anti-collision cylinder 275 exceeds the bellows 279. The gear ring 272, the anti-collision cylinder 275 and the third through hole are coaxially arranged, and a forward and reverse motor 278 is coaxially connected to one side of the gear 277.

[0053] Specifically, after the cable enters the cooling box 24, the cable will pass through the annular support frame 271, the gear ring 272, the liquid storage ring 273 and the anti-collision cylinder 275 in sequence. Under the driving action of the forward and reverse motor 278, the gear 277 rotates, thereby driving the gear ring 272 to rotate around the periphery of the cable. Since the annular support frame 271 is fixed in the cooling box 24, the annular support frame 271 can limit the displacement of the gear ring 272, but will not affect the rotation of the gear ring 272. Driven by the gear ring 272, the liquid storage ring 273 and the nozzle 274 rotate around the periphery of the cable. At the same time, through the bellows 279 and the water pipe 25, the coolant in the liquid storage tank 214 corresponding to the cooling box 24 can enter the liquid storage ring 273 and be sprayed on the periphery of the cable through the nozzle 274. At the same time, during the transmission of the cable, the nozzle 274 rotates around the periphery of the cable to ensure that the coolant can be evenly sprayed on the periphery of the cable, so that the cable can be evenly and quickly cooled.

[0054] Furthermore, a time relay is built into the forward and reverse motor 278. By setting the preset time of the time relay, the forward and reverse duration of the forward and reverse motor 278 can be controlled. When the preset time of the time relay is reached, the forward and reverse motor 278 changes from the forward state to the reverse state or from the reverse state to the forward state.

[0055] It is worth noting that, when the liquid storage ring 273 rotates, one end of the bellows 279 will also rotate accordingly, and the rotation of the bellows 279 may cause the bellows 279 to be wrapped around the outer periphery of the cable. Therefore, through the setting of the anti-collision cylinder 275, the cable enters the anti-collision cylinder 275 after the coolant is sprayed out by the nozzle 274, so that the bellows 279 will be directly wrapped around the anti-collision cylinder 275, which will not affect the normal transportation and cooling of the cable. At the same time, one end of the anti-collision cylinder 275 extends toward the gear ring 272 until one end of the anti-collision cylinder 275 exceeds the bellows 279. Further, one end of the anti-collision cylinder 275 exceeds the position of the bellows 279, but does not exceed the position of the nozzle 274. On the one hand, it is to ensure that the anti-collision cylinder 275 does not affect the effect of the coolant on the cable, and on the other hand, it is to ensure that the bellows 279 can be smoothly wrapped around the anti-collision cylinder 275 instead of the cable.

[0056] At the same time, by driving the gear ring 272 to rotate forward and reversely repeatedly through the forward and reverse motor 278, the bellows 279 can be reset after being wound around the anti-collision cylinder 275. At the same time, through the setting of the rotating joint 2710, the rotating structure 2710 can rotate freely on the liquid storage ring 273, thereby preventing the bellows 279 from getting tangled in the cooling box 24.

[0057] like Figure 7As shown, the dewatering assembly 28 is installed on one side of the cooling box 24, and the dewatering assembly 28 includes an air delivery cylinder 281 communicated with the cooling box 24, an exhaust fan 282 is provided in the air delivery cylinder 281, and the air delivery cylinder 281 is arranged between the second transmission roller 42 and the third transmission roller 43;

[0058] Specifically, since the coolant sprayed in the cooling box 24 has a certain temperature, the temperature inside the cooling box 24 will be increased. The hot air in the cooling box 24 can be discharged through the exhaust fan 282. At the same time, after the cable is cooled, it will be output outside the box 21 through the second transmission roller 42 and the third transmission roller 43. The air delivery cylinder 281 is just aligned with the cable between the second transmission roller 42 and the third transmission roller 43 to dry and remove the residual moisture on the surface of the cable to ensure that the subsequent packaging process can proceed smoothly.

[0059] The liquid storage tank 214 stores cooling liquid. Along the direction from the first transmission roller 41 to the second transmission roller 42, the temperature of the cooling liquid in the plurality of liquid storage tanks 214 gradually decreases, so that the temperature of the cooling liquid sprayed from the nozzles 274 in the plurality of cooling boxes 24 gradually decreases. When the cable enters the plurality of cooling boxes 24, the cable is cooled step by step by the cooling liquid with decreasing temperature, so that the cable realizes a cooling process with decreasing temperature in the plurality of cooling boxes 24, so as to avoid the insulation layer cracking and gap bubbles in the cable insulation layer caused by the large temperature difference between the cable and the cooling liquid. Meanwhile, correspondingly, along the direction from the second transmission roller 42 to the third transmission roller 43, the temperature of the hot air output from the air delivery cylinder 281 gradually increases, so as to ensure that after the cable is cooled, it undergoes a drying and dehydration process with increasing temperature step by step, so as to avoid a sudden increase in the cable temperature, that is, to ensure the integrity of the cable insulation layer and to fully remove the moisture on the cable surface, so as to ensure the smooth progress of the subsequent packaging process.

[0060] In this embodiment, the take-up roller 12 and the pay-off roller 11 are installed on the same side of the box body 21, two first through holes 22 are provided, and the two first through holes 22 are respectively provided corresponding to the take-up roller 12 and the pay-off roller 11, and the cable passes through the pay-off roller 11, one of the first through holes 22, the first transmission roller 41, the cooling box body 24, the second transmission roller 42, the third transmission roller 43, another first through hole 22, and the take-up roller 12 in sequence, so that the cable has a C-shaped structure in the box body 21. Specifically, the transmission process of the cable in the box body 21 can be roughly divided into two stages, the first stage is the process of the cable from the first transmission roller 41 to the second transmission roller 42, and the second stage is the process of the cable from the second transmission roller 42 to the third transmission roller 43;

[0061] Specifically, in the first stage, the cable will pass through several cooling boxes 24 to achieve a cooling process in which the temperature of the cable is gradually reduced. In the second stage, the cable is transported from the second transmission roller 42 to the third transmission roller 43. In the process again, the cable will pass through several air ducts 281 in turn. The air duct 281 will transport hot air to the cable at this stage to achieve a drying and dehydration process in which the temperature of the cable is gradually increased.

[0062] like Figure 2 As shown, in this embodiment, a test assembly 3 is also installed on the box body 21, and the test assembly 3 includes a test box body 32 fixed on the box body 21, an expansion airbag 33 is installed in the test box body 32, and the expansion airbag 33 is filled with helium. One side of the expansion airbag 33 is connected to the liquid storage tank 214 through a heat conducting rod 31, and a sensor switch 34 is provided below the expansion airbag 33. An expansion gap is left between the sensor switch 34 and the expansion airbag 33, and a display light 35 electrically connected to the sensor switch 34 is installed on the test box body 32;

[0063] Specifically, in common knowledge, when the temperature of a gas rises, its own volume will collide. Therefore, when the expansion airbag 33 is filled with helium, the expansion coefficient of helium is high, and the effect is high. Therefore, within a certain temperature range, the temperature in the liquid storage tank 214 can be roughly obtained by the expansion volume of the expansion airbag 33. Since it may be impossible to know whether the temperature of the coolant in the liquid storage tank 214 meets the standard during the actual use of the present application, the temperature of the coolant in the liquid storage tank 214 can be pre-measured by the test component 3 before the present application works. When the temperature of the coolant in the liquid storage tank 214 reaches the pre-measured temperature, the temperature of the coolant in the liquid storage tank 214 is measured. After the temperature is set, the expansion airbag 33 fills the expansion gap through the heat conduction effect of the heat-conducting rod 31. The expansion airbag 33 expands to contact and squeeze the sensing switch 34, and controls the display light 35 to flash, so as to remind the staff that the coolant temperature in the liquid storage tank 214 meets the preset temperature. When the coolant temperature in the liquid storage tank 214 does not meet the preset temperature, the expansion airbag 33 expands. When the temperature is not enough, the expansion airbag 33 will not expand to the extent of squeezing the sensing switch 34, so the display light 35 will not flash, and the coolant temperature in the liquid storage tank 214 will continue to increase.

[0064] In this embodiment, the expansion gap in the test box 32 gradually decreases along the direction from the first conveying roller 41 to the second conveying roller 42. The expansion gap in the present application can be pre-calculated at different preset temperatures by the expansion volume of the expansion airbag 33 at different preset temperatures and the heat consumption of the heat-conducting rod 31 when conducting heat. Since the coolant in the liquid storage tank 214 gradually decreases along the direction from the first conveying roller 41 to the second conveying roller 42, that is, the expansion volume of the expansion airbag 33 gradually decreases, the expansion gap needs to be gradually reduced.

[0065] like Figure 4 As shown, in this embodiment, a cleaning assembly 26 is installed between two adjacent cooling boxes 24, and the cleaning assembly 26 includes a cleaning cylinder 261 and a brush cylinder 262 installed in the cleaning cylinder 261, and both ends of the brush cylinder 262 are through-set, and both ends of the brush cylinder 262 are coaxially through-set with the second through hole 23, and the cleaning cylinder 261 is fixed in the box 21 through a first support rod 263;

[0066] It is understandable that in the process of the cable passing through two adjacent cooling boxes 24, it will pass through the cleaning component 26. During the transmission of the cable, the brush cylinder 262 can be used to brush off part of the liquid on the cable surface on the one hand, and on the other hand, it can brush off stains and impurities on the cable surface to ensure the cleanliness of the cable surface.

[0067] In this embodiment, a drainage port 213 is provided on one side of the cooling box 24, and a plurality of transversely distributed drainage grooves 29 are provided at the bottom of the box 21. One side of the drainage groove 29 is connected to a water collecting tank 210, and a plurality of drainage holes 211 are distributed in an array in the water collecting tank 210.

[0068] Specifically, during the process of the nozzle 274 in the cooling box 24 continuously spraying the coolant, the coolant will gradually accumulate in the cooling box 24 , and the used coolant can be discharged through the drain port 213 and discharged outside the box 21 through the drain groove 29 and the water collection groove 210 .

[0069] In this embodiment, the depth of the drainage groove 29 gradually increases along the direction from the cooling box 24 to the water collecting groove 210, so that the drainage groove 29 forms a certain slope to prevent the coolant from staying in the drainage groove 29, and at the same time, the effect of quickly draining the coolant into the water collecting groove 210 can be achieved.

[0070] In this embodiment, the drainage hole 211 passes through the bottom plate 13, and a water collecting tank 212 is correspondingly arranged under the bottom plate 13. After the coolant is discharged out of the box body 21, the used coolant can be collected again through the water collecting tank 212. At the same time, the coolant in the water collecting tank 212 can be filtered and then re-input into the liquid storage tank 214 through a pipeline, thereby realizing the recycling of the coolant and avoiding waste of resources.

[0071] like Figure 8 , 9As shown in FIG. 10, in this embodiment, the annular support frame 271 is fixedly connected to the cooling box 24 through a third support rod 2712, and a step block 2713 is fixed on a side of the gear ring 272 close to the annular support frame 271, and the width of the step block 2713 gradually increases along the direction from the gear ring 272 to the annular support frame 271, and a step groove 2714 adapted to the step block 2713 is opened on a side of the annular support frame 271 close to the gear ring 272;

[0072] Specifically, by engaging the step block 2713 in the step groove 2714, the step block 2713 can slide in an annular manner in the step groove 2714. The step groove 2714 is an annular groove, which on the one hand facilitates the rotation of the ring gear 272, and on the other hand can limit the displacement of the ring gear 272 to prevent the ring gear 272 from detaching from the annular support frame 271.

[0073] In this embodiment, a sponge tube 2711 with two ends penetrating therein is fixed in the anti-collision tube 275. The sponge tube 2711 is coaxially penetrating with the gear ring 272 and the second through hole 23. The anti-collision tube 275 is fixed in the cooling box 24 through a second support rod 276.

[0074] Specifically, after the cable is cooled by the coolant sprayed by the nozzle 274, it will enter the anti-collision cylinder 275. The sponge brush 2711 can be used to perform preliminary cleaning on the cable surface and remove the coolant, ensuring that there are no stains and impurities on the cable surface after the cooling process, and the coolant content on its surface is relatively low.

[0075] In summary, the surface cooling device for cable production in the above-mentioned embodiment of the present invention, through a plurality of horizontally distributed cooling boxes 24, the cooling boxes 24 rotate the cooling mechanism 27 to evenly spray the coolant in the liquid storage tank 214 on the surface of the cable, and the temperature of the coolant in the liquid storage tank 214 gradually decreases from the first transmission roller 41 to the second transmission roller 42, so that the cable can achieve a cooling process with a gradually decreasing temperature in the plurality of cooling boxes 24, thereby avoiding the cracking of the insulation layer of the cable and the generation of gap bubbles due to the large temperature difference between the cable and the coolant. At the same time, the hot air in the cooling box 24 is output to the surface of the cable through the dewatering component 28, and the moisture on the surface of the cable is further dried and removed to ensure that the subsequent packaging process can proceed smoothly.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
