Description

Technical Field

[0001] The present application relates to the technical field of cable production, and in particular to a cooling device for cable production. Background Art

[0002] At present, in the production process of cables, most of them need to be twisted by a stranding machine, and sometimes an inner shielding layer is wrapped on the outside of the core wire, and then the outer side of the core wire is covered with a plastic insulation layer by an extruder, and the insulation layer is mostly a rubber sleeve. Among them, the cable just injected from the extruder needs to be cooled and shaped in a cooling water tank. The cooling water tank is mostly a long strip tank, which allows the rubber insulation layer to be quickly shaped.

[0003] Regarding the above-mentioned related technologies, in order to ensure the molding efficiency of the extruder, the extruder generally maintains a certain wire output efficiency, that is, the cable delivery rate is mostly maintained within a certain range. In order to ensure that the cable has enough cooling time, so that the rubber sleeve can be quickly molded and the cable can be shipped quickly, the length of the cooling water tank is mostly lengthened so that the cable has a longer cooling time in the water tank, but this will cause the cooling water tank to occupy too much space, so it needs to be improved. Utility Model Content

[0004] In order to ensure that the cable has sufficient cooling time in a limited space, the present application provides a cooling device for cable production.

[0005] The present application provides a cooling device for cable production using the following technical solution:

[0006] A cooling device for cable production comprises a trough body, wherein a notch is arranged at the upper end of the trough body, one end of the trough body is the input end of the cable, and the other end of the trough body opposite to the output end of the cable, guide wheels are rotatably arranged at positions near the output end and the input end of the trough body, the rotation axis of the guide wheel is arranged in the horizontal direction and perpendicular to the cable conveying direction, and the lower end of the guide wheel is located in the trough body.

[0007] By adopting the above technical solution, room temperature water or cold water can be filled in the tank body. When the cable is injected out of the extruder, it enters the water in the tank body from the input end. The cable is first wound around the outer side of the lower end of the guide wheel near the output end, then leaves the water surface upward, and then comes back and winds around the outer side of the guide wheel near the input end, so that the cable continues to enter the water for cooling, and then comes out from the output end. Therefore, without changing the length of the tank body, the cable can be cooled for a second time, thereby ensuring that the cable has sufficient cooling time in a limited space.

[0008] Preferably, the guide wheel comprises a wheel body and a rotating shaft, the rotating shaft is passed through and rotatably connected to the axis position of the wheel body, and both ends of the rotating shaft are detachably connected to the trough body.

[0009] By adopting the above technical solution, the rotating shaft and the wheel body are rotatably connected, and the rotating shaft is detachably connected to the groove body, so that it can be easily disassembled when the guide wheel is not in use; when the rotating shaft is installed in the groove body, the wheel and the cable are wrapped around the outside of the wheel body for transportation, the wheel body can rotate, reducing the wear between the cable and the wheel body.

[0010] Preferably, at least one wheel body is provided on each rotating shaft, and the wheel bodies are arranged at intervals along the length direction of the rotating shaft on which the wheel body is installed.

[0011] By adopting the above technical solution, the cable can be wound back and forth around different wheels to cool the cable more times.

[0012] Preferably, an annular guide groove is provided on the outer circumference of the wheel body.

[0013] By adopting the above technical solution, when the cable is wound around the outside of the wheel body for transportation, the cable is wound around the guide groove, and the guide groove can limit the movement of the cable in the direction of the axis of the rotating shaft, thereby reducing the cable from detaching from the wheel body during transportation and improving the stability of the cable when being transported on the guide wheel.

[0014] Preferably, a bearing is coaxially fixed at the axial center position of the wheel body, and the rotating shaft passes through and is fixed to the inner ring of the bearing.

[0015] By adopting the above technical solution, the setting of the bearing ensures smooth rotation between the wheel body and the rotating shaft, and when the cable is wrapped around the outside of the guide wheel for transportation, the wear between the outside of the cable and the wheel body is reduced.

[0016] Preferably, sleeves covering the bearings are sealed and fixed on opposite sides of the wheel body, the rotating shaft passes through the sleeves, and the sleeves are higher than the water surface of the tank body.

[0017] By adopting the above technical solution, since a part of the wheel body is located in the water of the trough body, when the wheel body rotates, water will flow along the side wall of the wheel body to the bearing. After the water contacts the bearing, it is easy to cause the bearing to rust, affecting the smooth rotation of the bearing; and the sleeve can block the two sides of the bearing. When water flows downward from the surface of the wheel body, the sleeve can block the water flow, reduce the water contacting the bearing, and thus reduce the rust of the bearing.

[0018] Preferably, the outer diameter of the sleeve gradually increases in a direction away from the wheel body.

[0019] By adopting the above technical solution, the sleeve is made into a conical cylinder. When water flows to the outer surface of the sleeve, the water flows from the opening of the sleeve away from the wheel body to the inner wall of the sleeve, which further reduces the contact between water and the bearing.

[0020] Preferably, a convex edge is fixed on the circumferential outer side of the sleeve.

[0021] By adopting the above technical solution, when water flows to the outer surface of the sleeve, the convex edge can block it, thereby reducing the water flowing from the opening of the sleeve away from the wheel body to the inner wall of the sleeve.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] (1) By setting the coordination between the trough body and the guide wheel, the cable can be cooled secondary along the length direction of the trough body without increasing the length of the trough body, thereby achieving the effect of ensuring that the cable has sufficient cooling time in a limited space;

[0024] (2) By setting the matching between the bearing and the sleeve, the wheel body can be ensured to rotate smoothly, reducing the wear between the cable and the wheel body. At the same time, the sleeve can reduce the contact of water with the bearing and reduce the rust of the bearing;

[0025] (3) By arranging at least one wheel on each rotating shaft, the cable can be cooled reciprocatingly more times to ensure sufficient cooling time for the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a cooling device for cable production. Figure 1The cooling device includes a tank body 1 and a guide wheel 2. The tank body 1 is a rectangular parallelepiped, and a square notch 3 is provided on the upper end surface of the tank body 1. Normal temperature water or ice water can be added into the tank body 1 as a cooling medium. One end of the tank body 1 in the length direction is the input end of the cable, and the other end of the tank body 1 opposite to the cable output end. After the cable is overmolded from the extruder, it enters the tank body 1 from the input end and is cooled by water. The cable is transported along the length direction of the tank body 1 and finally leaves the tank body 1 from the output end.

[0033] Among them, refer to Figure 1 and Figure 2 There are two guide wheels 2, which are rotatably connected to the positions of the trough body 1 near the output end and the input end. The rotation axis of the guide wheel 2 is arranged in the horizontal direction and is perpendicular to the cable conveying direction. The lower end of the guide wheel 2 is located in the trough body 1 and in the water. When the cable just enters the water of the trough body 1, the cable first passes through the side of the guide wheel 2 near the input end. At this time, the cable does not contact the guide wheel 2 near the input end. Then the cable is wound around the outside of the guide wheel 2 near the output end, and then goes upward into the air. Finally, it is wound around the outside of the guide wheel 2 near the input end. The cable re-enters the water of the trough body 1 for secondary cooling. Therefore, without changing the length of the trough body 1, the effect of ensuring that the cable has sufficient cooling time in a limited space is achieved.

[0034] In some embodiments, reference Figure 2 and Figure 3 The guide wheel 2 includes a wheel body 21 and a rotating shaft 22. The wheel body 21 is circular. The rotating shaft 22 is passed through and rotatably connected to the axis of the wheel body 21. Both ends of the rotating shaft 22 are detachably connected to the tank body 1, which is convenient for disassembling the guide wheel 2. The cable can change the conveying direction around the outer side of the wheel body 21. A bearing 4 is coaxially fixed at the axis position of the wheel body 21. The rotating shaft 22 is passed through and fixed to the inner ring of the bearing 4, which can improve the smooth rotation connection between the wheel body 21 and the rotating shaft 22 and reduce the wear between the cable and the wheel body 21.

[0035] Among them, the two ends of the rotating shaft 22 are locked to the upper end surface edge of the trough body 1 through the arc pressure plate 5 and the screw 6. The arc pressure plate 5 presses the end of the rotating shaft 22, and the arc pressure plate 5 is locked to the trough body 1 through the screw 6 to realize the quick and detachable connection of the upper guide wheel 2, and it is convenient to adjust the installation position of the wheel body 21.

[0036] In some embodiments, at least one wheel body 21 is provided on each rotating shaft 22. In this embodiment, two wheels 21 are provided on each rotating shaft 22. The wheels 21 are arranged at intervals along the length direction of the rotating shaft 22 on which they are installed, and the planes where the wheels 21 are located are parallel and staggered. According to cooling needs, the cable can be reciprocated around different wheels 21 along the length direction of the tank body 1 to cool the cable in water more times, further improving the cooling time of the cable in water.

[0037] In some embodiments, an annular guide groove 7 is provided on the outer circumference of the wheel body 21, and the cable is wound in the guide groove 7, which can reduce the cable from falling off the guide wheel 2 and improve the stability of the cable during transportation.

[0038] In some embodiments, sleeves 8 covering the bearings 4 are sealed and fixed to the two opposite planes of the wheel body 21. In this embodiment, the cross section of the sleeve 8 is circular. In other schemes, the cross section of the sleeve 8 can also be triangular, rectangular or polygonal, as long as the ends of the sleeve 8 can completely cover the side area of ​​the bearings 4. The ends of the sleeve 8 are fixed to the two side planes of the wheel body 21 by sealant, the shaft 22 passes through the sleeve 8, and the lower side of the sleeve 8 is higher than the water level of the tank body 1, reducing the water from entering the sleeve 8. Since a part of the wheel body 21 is located in the water of the tank body 1, when the wheel body 21 rotates, water will flow down along the side wall of the wheel body 21 to the bearing 4. After the water contacts the bearing 4, it is easy to cause the bearing 4 to rust, affecting the smooth rotation of the bearing 4; and the sleeve 8 can block the two sides of the bearing 4. When the water flows down from the surface of the wheel body 21, the sleeve 8 can block the water flow, reducing the water from contacting the bearing 4, so as to reduce the possibility of the bearing 4 rusting.

[0039] In some embodiments, a flange 9 is fixed to the circumferential outer side of the sleeve 8 , and the flange 9 surrounds the circumference of the sleeve 8 , which can further play a blocking role and reduce the flow of water from the opening of the sleeve 8 away from the wheel body 21 to the inner wall of the sleeve 8 .

[0040] In some embodiments, reference Figure 4 The outer diameter of the sleeve 8 gradually increases in the direction away from the wheel body 21, so that the sleeve 8 is in a cone shape as a whole, which can reduce the flow of water from the opening of the sleeve 8 away from the wheel body 21 to the inner wall of the sleeve 8.

[0041] The implementation principle of a cooling device for cable production in an embodiment of the present application is as follows: when the cable just enters the water in the trough body 1, the cable first passes through the side of the guide wheel 2 close to the input end. At this time, the cable does not contact the guide wheel 2 close to the input end. Then the cable is wound around the outside of the guide wheel 2 close to the output end, then goes upward into the air, turns back in the direction close to the input end, and finally is wound around the outside of the guide wheel 2 close to the input end, and goes downward into the water, so that the cable re-enters the water in the trough body 1 for secondary cooling. Therefore, without changing the length of the trough body 1, the effect of ensuring that the cable has sufficient cooling time in a limited space is achieved.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
