[0025] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 3 As shown, this embodiment provides a precooling device 100 for a cable production line, which is used to precool the cable 10 that enters the liquid cooling component 70 for cooling. When the cable 10 is processed with an outer sheath, the outer sheath needs to enter the liquid cooling component 70 for cooling after being extruded from the die head to improve the strength of the outer sheath. The liquid cooling component 70 generally uses a cooling water tank 710. After the cable 10 completes the extrusion molding operation of the outer sheath, the cable 10 needs to be pulled into the cooling water tank 710 to quickly cool the outer sheath of the cable 10 and improve its strength.

[0027] The precooling device 100 for a cable production line includes a precooling pipe 20 and a blowing member 30. The precooling pipe 20 includes a first pipe portion 21 and a second pipe portion 22, and the first pipe portion 21 and the second pipe portion 22 are detachably connected. The first pipe portion 21 and the second pipe portion 22 are arranged to form a cooling channel 201, and the cooling channel 201 is for the cable 10 to pass through. The precooling pipe 20 is provided with an air inlet 202, and the air inlet 202 is connected to the cooling channel 201. The blowing member 30 is detachably connected to the precooling pipe 20, and the air outlet end of the blowing member 30 is connected to the air inlet 202.

[0028] In this way, the precooling device 100 for the cable production line of the present application pulls the cable 10 to pass through the precooling tube 20, and blows air into the precooling tube 20 through the blowing member 30, thereby cooling the outer surface of the cable 10 passing through the precooling tube 20, and avoiding problems such as water spot marks on the outer surface of the cable 10 due to the large temperature difference between the outer surface of the cable 10 and the coolant when the cable 10 enters the liquid cooling component 70. In addition, the precooling tube 20 is composed of a first tube portion 21 and a second tube portion 22, and the precooling tube 20 can be separated and covered on the outer periphery of the cable 10, avoiding the need to slowly pull the cable 10 from one end of the precooling tube 20 to pass through the precooling tube 20, thereby improving processing efficiency. At the same time, the blowing piece 30 is detachably connected to the precooling tube 20, which facilitates the synchronous movement of the blowing piece 30 and the precooling tube 20. By rotating the precooling tube 20, the airflow blown by the blowing piece 30 can alternately act on different areas of the outer surface of the cable 10, thereby improving the precooling effect.

[0029] For the convenience of subsequent reading, the present application introduces a first direction Z, a second direction X, and a third direction Y to describe the embodiments of the present application. The first direction Z, the second direction X, and the third direction Y may be three non-parallel linear directions in space; further, the first direction Z, the second direction X, and the third direction Y may be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In the subsequent embodiments, the first direction Z is the Z-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction X is the X-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction Y is the Y-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0030] Please combine again Figure 1 to Figure 2 In one embodiment, the precooling tube 20 is substantially a hollow columnar structure, and the extension direction of the precooling tube 20 is parallel to the third direction Y.

[0031] The first tube portion 21 and the second tube portion 22 are arranged in sequence along the first direction Z. The first tube portion 21 and the second tube portion 22 have substantially the same structure and shape, and the precooling tube 20 is formed by splicing the first tube portion 21 and the second tube portion 22. Along the first direction Z, a first channel 210 is provided on one side of the first tube portion 21 close to the second tube portion 22, and a second channel 220 is provided on one side of the second tube portion 22 close to the first tube portion 21. When the first tube portion 21 and the second tube portion 22 are connected, the first channel 210 communicates with the second channel 220, and the first channel 210 and the second channel 220 together form a cooling channel 201. The size of the cooling channel 201 is larger than the size of the cable 10 to prevent the cable 10 from contacting the tube wall of the precooling tube 20.

[0032] In this embodiment, the air inlet 202 includes a first air inlet 212 and a second air inlet 222. Along the first direction Z, the first tube portion 21 is provided with a first air inlet 212 on a side away from the second tube portion 22, and the first air inlet 212 is connected to the first channel 210. The second tube portion 22 is provided with a second air inlet 222 on a side away from the first tube portion 21, and the second air inlet 222 is connected to the second channel 220. The extension directions of the first air inlet 212 and the second air inlet 222 are both parallel to the first direction Z. The blowing member 30 includes a first blowing member 31 and a second blowing member 32, the first air outlet end of the first blowing member 31 is connected to the first air inlet 212, and the second air outlet end of the second blowing member 32 is connected to the second air inlet 222. In this way, by blowing air on both sides of the cable 10 in the first direction Z at the same time through the first blowing member 31 and the second blowing member 32, convection can be formed to improve the pre-cooling effect of the cable 10.

[0033] It is understandable that, in other embodiments, the number of the first air inlets 212 is multiple. Along the third direction Y, the multiple first air inlets 212 are arranged in sequence and spaced apart. The number of the second air inlets 222 is multiple. Along the third direction Y, the multiple second air inlets 222 are arranged in sequence and spaced apart. The number of the first blowing members 31 is the same as the number of the first air inlets 212, and the first blowing members 31 are arranged in a one-to-one correspondence with the first air inlets 212. The number of the second blowing members 32 is the same as the number of the second air inlets 222, and the second blowing members 32 are arranged in a one-to-one correspondence with the second air inlets 222. In this way, by increasing the number of the first blowing members 31 and the second blowing members 32, it is possible to simultaneously perform blowing precooling on each section of the cable 10 in its extension direction, which is suitable for cables 10 with a longer length and can improve the precooling efficiency of such cables 10.

[0034] In the present embodiment, the first blowing member 31 and the second blowing member 32 are devices capable of blowing air, such as vortex blowers. Along the first direction Z, the first blowing member 31 is detachably connected to the side of the first tube portion 21 away from the second tube portion 22, and the second blowing member 32 is detachably connected to the side of the second tube portion 22 away from the first tube portion 21. The first blowing member 31 can be mounted on the first tube portion 21 by bolts and other elements, so as to facilitate the disassembly and assembly of the first blowing member 31. For example, holes can be opened on the first blowing member 31 and the first tube portion 21, and the first blowing member 31 can be connected to the first tube portion 21 by bolts passing through the opened holes. The connection method of the second blowing member 32 and the first blowing member 31 is roughly the same, and will not be repeated.

[0035] Please combine again Figure 1 to Figure 2 In one embodiment, the precooling device 100 for a cable production line further includes a connecting structure 40. The first tube portion 21 and the second tube portion 22 are detachably connected by the connecting structure 40, and the connecting structure 40 is configured to clamp the first tube portion 21 and the second tube portion 22.

[0036] Along the second direction X, the first tube portion 21 is provided with first connecting portions 211 on opposite sides thereof, the extension direction of the first connecting portions 211 is parallel to the second direction X, and the two first connecting portions 211 are integrally formed with the first tube portion 21. Along the second direction X, the second tube portion 22 is provided with second connecting portions 221 on opposite sides thereof, the extension direction of the second connecting portions 221 is parallel to the second direction X, and the two second connecting portions 221 are integrally formed with the second tube portion 22.

[0037] The two second connection parts 221 are arranged correspondingly to the two first connection parts 211. When the first tube part 21 and the second tube part 22 are spliced, the two second connection parts 221 and the two first connection parts 211 respectively abut against each other in the first direction Z. Any one of the two first connection parts 211 is detachably connected to the corresponding second connection part 221 through a connection structure 40 to improve the stability of the connection between the first tube part 21 and the second tube part 22.

[0038] In this embodiment, the connection structure 40 includes a connection member 41. A first connection hole 2110 is provided on the first connection portion 211, and the first connection hole 2110 penetrates the first connection portion 211 along the first direction Z. A second connection hole 2210 is provided on the second connection portion 221, and the second connection hole 2210 penetrates the second connection portion 221 along the first direction Z. The connection member 41 is penetrated through the first connection hole 2110 and the second connection hole 2210, and the connection member 41 is configured to connect the first connection portion 211 and the second connection portion 221. For example, the connection member 41 can be a threaded element such as a bolt, and the first connection hole 2110 and the second connection hole 2210 are both threaded holes, thereby realizing a threaded connection between the connection member 41 and the first connection portion 211 and the second connection portion 221.

[0039] It is understandable that in other embodiments, the number of the first connection holes 2110 is multiple. Along the third direction Y, the multiple first connection holes 2110 are sequentially spaced apart. Correspondingly, the number of the second connection holes 2210 and the connection members 41 is multiple, and the multiple second connection holes 2210 and the multiple connection members 41 are arranged one-to-one with the multiple first connection holes 2110 to improve the fastness of the connection between the first tube portion 21 and the second tube portion 22.

[0040] Furthermore, the connection structure 40 further includes a locking member 42. The extension length of the connection member 41 is greater than the sum of the extension lengths of the first connection hole 2110 and the second connection hole 2210, so that both ends of the connection member 41 respectively pass through the first connection hole 2110 and the second connection hole 2210. A stopper 410 is protruded from one end of the connection member 41 passing through the first connection hole 2110, and one end of the connection member 41 passing through the second connection hole 2210 is connected to the locking member 42.

[0041] The outer diameters of the limiting portion 410 and the locking member 42 are both larger than the outer diameter of the connecting member 41. The limiting portion 410 abuts against a side of the first connecting portion 211 away from the second connecting portion 221, and the locking member 42 abuts against a side of the second connecting portion 221 away from the first connecting portion 211, thereby clamping the first connecting portion 211 and the second connecting portion 221 between the limiting portion 410 and the locking member 42, thereby improving the tightness when the first pipe portion 21 and the second pipe portion 22 are connected.

[0042] In this embodiment, the locking member 42 may be a threaded element such as a nut, and the locking member 42 is threadedly connected to the connecting member 41 for easy assembly and disassembly.

[0043] Please combine again Figure 1 to Figure 2 In one embodiment, the precooling tube 20 is configured to be rotatable relative to the cable 10. The precooling device 100 for the cable production line also includes a bracket 60 and a rotating seat 50. The bracket 60 is provided with a rotating groove, and the rotating groove penetrates the bracket 60 along the third direction Y. The rotating seat 50 is sleeved on the outer circumference of the bracket 60, and the rotating seat 50 is rotatably installed in the rotating groove. The rotating seat 50 can be driven by a motor or other device to rotate relative to the bracket 60, thereby realizing the rotation of the precooling tube 20 fixedly connected to the rotating seat 50 relative to the bracket 60, so that the first blowing member 31 and the second blowing member 32 are rotated to blow air to different areas of the cable 10 located in the precooling tube 20, thereby improving the precooling efficiency of the cable 10.

[0044] like Figure 3 See Figure 1 to Figure 2 This embodiment also provides a cooling device 200 for a cable production line, including a liquid cooling component 70 and the above-mentioned pre-cooling device 100 for a cable production line.

[0045] The liquid cooling assembly 70 is provided at the cable outlet end of the precooling device 100 for the cable production line along the pulling direction of the cable 10, and the liquid cooling assembly 70 is configured to cool the cable 10 that has completed the precooling operation. The liquid cooling assembly 70 includes a plurality of cooling pools 71. Along the third direction Y, the plurality of cooling pools 71 are arranged in sequence, and each cooling pool 71 is provided with a cooling water tank 710, and cooling water is injected into the cooling water tank 710.

[0046] Among them, the cooling water trough 710 of the cooling pool 71 closest to the precooling pipe 20 among the multiple cooling pools 71 is connected to the cooling channel 201, so that the cable 10 that has completed the precooling operation can be immediately sent into the cooling water trough 710 to be immersed in cooling water and quickly cooled.

[0047] In the above, the specific embodiments of the present application are described with reference to the accompanying drawings. However, those skilled in the art will appreciate that various changes and substitutions may be made to the specific embodiments of the present application without departing from the scope of the present application. These changes and substitutions are all within the scope defined by the present application.
