[0001] The present invention relates to the technical field of cable production, and in particular to a cable centering device and a cable production system. Background Art

[0002] With the rapid development of the cable industry, almost all major projects and equipment have an increasing demand for cables, and the performance and quality requirements are also getting higher and higher.

[0003] At present, the cable industry mostly uses vertical tower type high-voltage line production lines for cable production. Since the vertical tower type high-voltage line production line can well ensure the cylindricity of the cable during the vulcanization stage and ensure the high quality of the cable, it has been used.

[0004] The cable production line includes an automatic cable centering mechanism at the outlet of the cable water tank. Since the cable inevitably shakes left and right during the production process, the automatic cable centering mechanism can center the cable during cable production. The current automatic cable centering mechanism is a rigid mechanical clamping structure, which is easy to bend the cable rigidly or cause irreversible damage to the surface of the cable, which will seriously affect the quality and performance of the cable, so that the produced cable does not meet the quality requirements and causes waste. Summary of the invention

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] refer to Figure 1 and Figure 2 An exemplary cable centering device is shown. The cable centering device provided by the present invention includes a base 1 and a cable supporting unit 2. The cable supporting unit 2 is rotatably arranged on a base surface of the base 1. The rotation axis of the cable supporting unit 2 is perpendicular to the base surface, wherein the cable supporting unit 2 includes a supporting channel 3 for the cable to pass through.

[0025] Since the cable support unit 2 is formed with a support channel 3, the cable 4 can pass through the support channel 3 and be supported by the support channel 3 to avoid being clamped and shaking left and right and damaging the surface layer. At the same time, since the cable support unit 2 can be rotatably arranged, even if the cable 4 shakes left and right during the cable production process, the cable 4 will drive the cable support unit 2 to rotate accordingly to avoid the cable 4 from being rigidly bent. In this way, the cable centering device can effectively alleviate or avoid rigid bending of the cable 4 and damage to the cable surface layer, thereby improving the quality of the cable 4.

[0026] Furthermore, in the actual production of cables, the cables may jump or shake up and down. Therefore, in order to further prevent the cables from being rigidly bent or the cable surface layer from being damaged, preferably, the cable support unit 2 can adjust the position in the direction of the rotation axis. In this way, when the cable jumps or shakes up and down, the cable support unit 2 will adjust the position up and down accordingly to adapt to the up and down jumping or shaking of the cable.

[0027] Of course, the up and down adjustment position of the cable support unit 2 can be achieved in a variety of ways. For example, in one way, when the cable shakes or jumps up and down, it will directly drive the cable support unit 2 to adjust its position up and down. For example, the rotating shaft of the cable support unit 2 can be rotatably set on the base through a bearing, and at the same time the rotating shaft can move up and down relative to the bearing.

[0028] Alternatively, the cable support unit 2 can be driven by a driving device such as a motor gear rack, the rack is arranged on the cable support unit 2, and the motor can be controlled by the control unit to rotate forward and reverse to drive the rack to move up and down, and the up and down shaking of the cable can be detected by a sensor such as a position sensor or an infrared sensor in real time and send a signal to the control unit, so that the signal of the up and down shaking of the cable is transmitted to the control unit, and the control unit controls the motor accordingly, so that the motor moves the cable support unit accordingly through the rack.

[0029] Of course, it should be understood that the implementation method of adjusting the up and down position of the cable support unit 2 of the present invention is not limited to the above two methods. No matter which method is adopted, as long as the cable support unit 2 can move in real time with the up and down shaking or jumping of the cable, it will be fine.

[0030] In addition, in order to further avoid damage to the cable skin layer, preferably, a flexible layer, such as a silicone layer or a nylon layer, is provided on the inner circumference of the support channel 3, so that the cable 4 can be further prevented from being scratched by the flexible layer. Of course, when the cable moves through the flexible layer, the flexible layer can also significantly reduce the moving noise of the cable. In particular, when the flexible layer is a nylon layer with low hardness and self-lubricating effect, the effect of preventing the cable from being scratched and reducing the moving noise is more obvious.

[0031] Of course, the channel wall of the supporting channel 3 may be made of other materials, such as metal or ceramic, etc., as long as a flexible layer is formed on the inner circumferential surface of the supporting channel 3 .

[0032] Alternatively, preferably, in order to increase the service life and reduce the weight of the cable support unit 2, so that the cable can more easily drive the cable support unit 2 to rotate, and more preferably adjust the position up and down, the cable support unit 2 includes a support shell having a support channel 3, wherein the support shell is a flexible shell rotatably arranged on the base 1. That is, the support shell is formed of a flexible material as a whole. In this way, it is possible to avoid the formation of a flexible layer on the inner circumference of the support channel 3.

[0033] Of course, the flexible shell can be made of appropriate flexible materials, such as materials with low hardness and self-lubricating properties. Preferably, the flexible shell is a nylon shell.

[0034] Of course, the nylon shell can be a single complete shell, the internal channel of the shell forms the support channel 3, or the support shell can be formed by two halves of the shell part, such as two halves of the nylon shell, being butted together.

[0035] Or, if Figure 1 and Figure 2As shown, the support housing includes a first housing portion 5 and a second housing portion 6 which are rotatably arranged in any appropriate manner, wherein the first housing portion 5 and the second housing portion 6 are respectively formed with a cavity, which may have various forms such as a semicircular cavity, and the first housing portion 5 and the second housing portion 6 are arranged in a manner that the cavities face each other so that the cavities of the two together form a support channel 3. In this way, as Figure 1 As shown, after the cable 4 passes through the supporting channel 3 , when the cable 4 swings left and right, the first housing portion 5 and the second housing portion 6 will be driven to rotate slightly accordingly to adapt to the left and right swing of the cable 4 .

[0036] Of course, a proper distance may be maintained between the first housing portion 5 and the second housing portion 6 , so that the first housing portion 5 and the second housing portion 6 can be more easily rotated slightly as the cable 4 shakes left and right.

[0037] The first housing portion 5 and the second housing portion 6 can be directly rotatably disposed on the base 1, or, further, in order to facilitate maintaining an appropriate distance between the bottom surfaces of the first housing portion 5 and the second housing portion 6 and the base 1, such as Figure 1 and Figure 2 As shown, two slewing bearings 7 arranged at intervals are provided on the base 1, and the cable support unit 2 includes a first support 8 rotatably arranged on the slewing bearing 7 and a second support 9 rotatably arranged on the other slewing bearing 7, wherein the first shell part 5 is arranged on the first support 8 and the second shell part 6 is arranged on the second support 9.

[0038] Furthermore, if Figure 1 and Figure 2 As shown, after the cable jumps left and right, in order to facilitate the return of the first shell part 5 and the second shell part 6, a flexible part 11 is connected between the outer circumference of the first shell part 5 and the outer circumference of the second shell part 6, so that under the action of the flexible part 11, the first shell part 5 and the second shell part 6 will return to drive the cable 4 to return to the center again.

[0039] Of course, the flexible member 11 can have various forms and be connected to the outer circumference of the first shell portion 5 and the second shell portion 6 in any appropriate manner. For example, the ends of the flexible member 11 can be connected to the outer circumference of the first shell portion 5 and the second shell portion 6 by bolts 12.

[0040] The flexible member 11 may be an elastic rubber strip or a spring, so that the spring can more easily return the first housing portion 5 and the second housing portion 6, thereby making it easier for the cable 4 to be returned to center; and / or, the first support 8 and the second support 9 can adjust their positions relative to their respective slewing bearings 7 along the direction of the rotation axis, so that the first housing portion 5 and the second housing portion 6 can adapt to the up and down jumping or shaking of the cable 4.

[0041] exist Figure 1 and Figure 2 In one example of the cable centering device shown, two slewing bearings 7 are arranged at intervals on the base 1, a first support 8 is rotatably arranged in one slewing bearing 7 so as to be able to rotate slightly, and a second support 9 is rotatably arranged in the other slewing bearing so as to be able to rotate slightly, and the first support 8 and the second support 9 can adjust their positions up and down relative to their respective slewing bearings, and the two halves of the nylon shell are respectively connected to the first support 8 and the second support 9 and are close to each other to form a support channel 3 between the two halves. Of course, an appropriate gap is maintained between the two halves of the nylon shell, and in addition, the spring is connected between the outer circumferences of the two halves of the nylon shell. In this way, when the cable passing through the support channel 3 deviates from the center, the two halves of the nylon shell can make a slight rotation to adapt to the slight movement of the cable and not damage the surface of the cable. After the cable is returned to the center, under the action of the spring force, the two halves of the nylon shell return to the normal position. At the same time, if the cable is not easy to return to the position, the spring force will assist the cable to return to the center through the nylon shell. When the speed of the cable traction machine is well matched, the cable is in a tensioned state to pass through the support channel 3, which can effectively alleviate the hard bending and skin damage of the cable and reduce the noise of cable movement. In this way, the damage to the cable can be reduced, the noise can be reduced, the shaking of the cable can be alleviated, the operation is stable, and the operation of subsequent processes is convenient.

[0042] In addition, the present invention provides a terminal water tank and a drying device for a cable production system, such as Figure 3 As shown, the terminal water tank and drying device of the cable production system include a bracket 10 and any of the cable centering devices described above. Along the cable output direction, the bracket 10 is provided with rollers located upstream of the cable centering device and can be pre-adjusted according to the production of different cable specifications.

[0043] In this way, as described above, the overall performance of the cable production system is improved, and the quality of the produced cables is reliable.

[0044] In addition, the support 10 can be a support included in a movable water tank system of a high-voltage tower cable and a medium-voltage catenary cable, such as Figure 2 As shown, the bracket 10 can be fixed on the water tank housing.

[0045] In addition, if Figure 3 As shown, since the roller can be pre-adjusted and the position can be adjusted on the bracket 10 along the height direction of the bracket 10 to adapt to the production of different specifications of cables 4 with up and down jumping or shaking, when producing large-specification cables, the pre-adjusted roller rotating shaft is adjusted downward, and when producing small-specification cables, the pre-adjusted roller rotating shaft is adjusted upward.

[0046] In addition, the cable centering device can also adjust the height accordingly according to the specifications of the cable. For example, a connecting rod is connected between the two end plates of the base 1, and an elongated hole extending in the height direction is provided on the bracket 10. The connecting rod passes through the elongated hole, so that the connecting rod can slide up and down in the elongated hole.
