Description

Technical Field

[0001] The present invention relates to the field of cable processing, and more specifically to a fireproof cable and its manufacturing process. Background Art

[0002] Cables are indispensable in modern society. During the manufacturing process of power cables, with the rapid development of urbanization, the demand for fireproof cables continues to be strong. For existing cables, the fireproof ability is poor, and when the fireproof cable encounters an external force, the effect of resisting the external force is relatively poor, and the protection effect on the conductor inside the fireproof cable is relatively poor. As a result, when the fireproof cable is subjected to an external force, the conductor inside the fireproof cable will be damaged, thus affecting the normal use of the fireproof cable. Therefore, a fireproof cable is needed to solve the above problems. When processing existing fireproof cables to ensure the fireproof effect, it is necessary to extrude the outer insulating skin to increase its density and enhance its stability at high temperatures. However, the high-density skin formed by extrusion causes it to shrink during cooling, thereby strengthening the penetration of the coolant, resulting in a long drying time for the cable and affecting the overall processing efficiency. Summary of the Invention

[0003] The present invention provides a fireproof cable and its manufacturing process, aiming to dry the cable during winding to increase processing efficiency.

[0004] The above object is achieved by the following technical solutions:

[0005] A fireproof cable processing device includes a driving disk and a driven disk, between which a plurality of support plates are slidably connected. A partition is slidably connected to each support plate. Each support plate is provided with a plurality of slots, and each partition is provided with clamping plates corresponding to the number of slots. A first telescopic rod is fixedly connected between each partition and the driving disk.

[0006] The fireproof cable processed by the fireproof cable processing device includes an internal cable core. A refractory rubber layer is fixedly connected to the surface of the cable core. A flame retardant layer is arranged inside the refractory rubber layer, and the outer surface of the refractory rubber layer is a high-density wear-resistant rubber layer.

[0007] The manufacturing process used by the fireproof cable processing device includes the following steps:

[0008] S1: Pass the cable core through the flame retardant layer, then extrude it through an extruder, and then compact the surface rubber layer by a pressure device, and then pass it through a coolant for cooling;

[0009] S2: Fix one end of the cooled cable on the first telescopic rod, and then control the driving shaft to rotate;

[0010] S3: Fix the cylinder shell for winding the cable between the first right support and the second right support;

Detailed Implementation Manner

[0024] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] As Figures 1 to 4 , to reduce the drying time of the coolant.

[0027] A plurality of support plates 202 are slidably connected between the driving disk 12 and the driven disk 201. Each partition plate 204 is slidably connected to the corresponding support plate 202. A plurality of slots are provided on each support plate 202, and a plurality of clamping plates corresponding to the number of slots are provided on each partition plate 204. A first telescopic rod 203 is fixedly connected between each partition plate 204 and the driving disk 12.

[0028] During processing, one end of the cable is first fixed to one end of a support plate 202, and then the driving disk 12 is driven to rotate, thereby driving a plurality of support plates 202 to rotate synchronously. At the same time, the driven disk 201 at the other end also rotates accordingly. During rotation, the cable is wound around the outer ends of the plurality of support plates 202. The entire device is placed on a platform that can move horizontally. Therefore, when winding, the device is driven to move to one side, so that the cable can be wound around the outside of the support plate 202 turn by turn. Each turn of the cable is separated by a plurality of clamping plates on the partition plate 204, so that there is a gap between each turn of the cable. At this time, air is released from the inside of the device to the outside, and the air flow can accelerate the evaporation of the coolant on the surface of the cable. After the cable passes through the extruder, the density of the rubber layer on its outer surface becomes higher through the pressure device. Since rubber itself has elasticity, when passing through the coolant, its own elasticity causes it to expand slightly, resulting in the surface of the cable being not easily dried. Therefore, through this device, the cable is further dried during winding, increasing the drying effect during cable processing, thereby increasing the service life of the cable by avoiding corrosion. When the cable is completely wound, a plurality of partition plates 204 are simultaneously moved inward, thereby driving the clamping plates to slide out of the slots. Then, a cylindrical shell for fixing is placed at one end of the plurality of support plates 202 from one side of the device, and then the cable is pushed from the other end to fix it outside the cylindrical shell.

[0029] As Figure 2 and Figure 3 , to solve the problem of winding cables with different diameters.

[0030] A first telescopic rod 203 is fixedly connected between each partition plate 204 and the driving disk 12.

[0031] Due to the requirements of different usage environments, the cable needs to be processed into different diameters. When winding it around the support plate 202, if the cable diameter is too long and exceeds the length of each clamping plate on the partition plate 204, it will easily fall off during the winding process. If the clamping plate is too long, the distance between the cable output end and the support plate 202 will be too far during winding, resulting in the cable being prone to collide with the clamping plate during winding, affecting the winding efficiency. Therefore, the first telescopic rod 203 is provided. When it contracts, it drives the support plate 202 to move inward, so that the length of the clamping plate exceeding the support plate 202 becomes longer, thus meeting the processing requirements for cables with a large diameter. Conversely, when the first telescopic rod 203 extends, it similarly meets the processing requirements for cables with a small diameter.

[0032] Such as Figure 4 , to solve the problem of blowing air outward from the inside of the support plate 202.

[0033] The rotating shaft 13 rotates coaxially with the driving disk 12 and is arranged inside multiple support plates 202. The wind wheel 301 is fixed on the rotating shaft 13.

[0034] When the cable is wound around the outside of the support plate 202, the internal rotating shaft 13 rotates synchronously, driving the wind wheel 301 to rotate at a high speed inside. Then, the air is blown out from around the wind wheel 301 and then to both ends. At this time, the high-speed flowing air passes through the surface of the cable, accelerating the drying effect of the coolant and preventing the residual coolant from corroding the cable and affecting its lifespan. The air flow is inhaled from all around and blown out from both sides, which can also make the dust in the air adhere to the outside of the cable coil as much as possible, facilitating the cleaning of the cable.

[0035] Such as Figure 6 And Figure 7 , to solve the problem of synchronous movement of multiple partition plates 204.

[0036] One end of a slide bar 205 is welded to each partition plate 204. A linkage disk 14 is arranged inside multiple support plates 202. The linkage disk 14 is provided with sliding grooves 401 corresponding to the number of slide bars 205. One end of each slide bar 205 is slidably connected in the corresponding sliding groove 401.

[0037] The chute 401 on the linkage disk 14 is inclined. When the linkage disk 14 rotates, it drives multiple inclined chutes 401 to rotate. Initially, one end of each slide bar 205 is located at the outer end of the corresponding chute 401. When the chute 401 rotates, the slide bar 205 moves inward along its slide, thereby driving the slide bar 205 to move inward, and then driving each partition plate 204 to move inward simultaneously, causing the clamping plate exceeding the support plate 202 to move inward, and thus no longer blocking the cable, facilitating the removal of the cable from one side. A tension spring is fixedly connected between the partition plate 204 and the support plate 202. When the linkage disk 14 rotates in the reverse direction, the tension spring contracts synchronously to reset the partition plate 204.

[0038] As Figure 8 and Figure 9 , to solve the problem of the rotation of the wind wheel 301.

[0039] The drive disk 12 is rotatably connected to the bracket 11. A drive shaft 15 is rotatably connected to the bracket 11. A third gear 501 is welded on the drive shaft 15. The rotating shaft 13 is rotatably connected to the bracket 11. A first gear 302 is fixedly connected to the rotating shaft 13. The first gear 302 and the third gear 501 mesh with each other.

[0040] When the drive shaft 15 rotates, it drives the third gear 501 to rotate, and then meshes with and drives the first gear 302 to rotate. At this time, the first gear 302 drives the rotating shaft 13 to rotate, thereby achieving the purpose of driving the wind wheel 301 to rotate.

[0041] As Figure 8 and Figure 9 , to solve the problem of the synchronous rotation of the drive disk 12 when the wind wheel 301 is working.

[0042] A toothed disk 208 is welded on the drive disk 12. The toothed disk 208 and the third gear 501 mesh with each other.

[0043] When the drive shaft 15 rotates, it drives the third gear 501 to rotate. At this time, it meshes with and drives the first gear 302 to rotate, driving the wind wheel 301 to work. When the third gear 501 rotates, it drives the toothed disk 208 to rotate. At this time, it drives the drive disk 12 to rotate to wind the cable, and thus simultaneously drives the wind wheel 301 to rotate to dry the wound cable.

[0044] As Figure 8 and Figure 9 , to solve the problem of the rotation of the linkage disk 14.

[0045] Multiple connecting rods 402 are welded on the linkage disk 14. The other ends of the multiple connecting rods 402 are welded with a second gear 403. The first gear 302 is meshed with the second gear 403 through sliding.

[0046] After the cable winding and drying are completed, the drive shaft 15 stops rotating. At this time, the movable drive shaft 15 drives the third gear 501 to move so that the third gear 501 meshes with the second gear 403. Then, the drive shaft 15 is driven to rotate, driving the third gear 501 to rotate. At this time, the meshing drives the second gear 403 to rotate, and then drives a plurality of connecting rods 402 to rotate, and then drives the linkage disk 14 to rotate, causing a plurality of partition plates 204 to move.

[0047] As Figure 9 and Figure 10 , to solve the problem of the movement of the drive shaft 15.

[0048] A sliding seat 103 is slidably connected to the bracket 11. A first motor is fixedly connected to the sliding seat 103. The output shaft of the first motor is fixedly connected to the drive shaft 15. The movable end of a second telescopic rod 104 is fixedly connected below the sliding seat 103, and the fixed end of the second telescopic rod 104 is fixed on the bracket 11.

[0049] When the first motor works, it drives the drive shaft 15 to rotate. When it is necessary to move the drive shaft 15, the second telescopic rod 104 is driven to contract, thereby driving the sliding seat 103 to move. At this time, the first motor and the drive shaft 15 are driven to move synchronously, so that the third gear 501 moves to mesh with the second gear 403.

[0050] As Figure 4 and Figure 5 , to solve the problem of removing the wound cable from the device.

[0051] On the other side of the bracket 11, there is a second right bracket 102. Above the second right bracket 102, there is a first right bracket 101. The first right bracket 101 and the second right bracket 102 are connected by an insertion plate. The rotating shaft 13 is rotatably connected to the first right bracket 101. A push plate 207 is slidably connected outside a plurality of support plates 202. A threaded rod 206 is rotatably connected between the bracket 11 and the second right bracket 102. The push plate 207 is threadedly connected to the threaded rod 206.

[0052] When winding, the insertion plate between the first right bracket 101 and the second right bracket 102 fixedly connects the two. When the cable is wound and dried, the rotating shaft 13 on one side of the first right bracket 101 is supported. Then, the insertion plate between the first right bracket 101 and the second right bracket 102 is removed, and the cylindrical shell to which the cable is fixed is sleeved between the first right bracket 101 and the second right bracket 102. After the partition plate 204 moves inward, the threaded rod 206 is driven to rotate, and then the push plate 207 is driven to move. As the push plate 207 moves, the cable outside the support plate 202 is pushed toward the cylindrical shell side, and then it is pushed onto the cylindrical shell for easy movement and storage.

[0053] The fire-resistant cable processed by this processing equipment includes an internal cable core made of metallic copper. A refractory rubber layer is fixedly connected to the surface of the cable core. A flame retardant layer is arranged inside the refractory rubber layer, and the outer surface of the refractory rubber layer is a high-density wear-resistant rubber layer.

[0054] Such as Figure 11 , a manufacturing process used in a fire-resistant cable processing equipment, includes the following steps:

[0055] S1: Pass the cable core through the flame retardant layer, then extrude it through an extruder. After that, compact the surface rubber layer with a pressure device, and then pass it through the coolant for cooling;

[0056] S2: Fix one end of the cooled cable on the first telescopic rod 203, and then control the driving shaft 15 to rotate to wind the cable around the outside of a plurality of support plates 202;

[0057] S3: Fix the cylindrical shell wound with the cable between the first right support 101 and the second right support 102;

[0058] S4: Drive the second telescopic rod 104 to contract, then control the driving shaft 15 to rotate to make the partition plate 204 contract inward, and then drive the threaded rod 206 to rotate to drive the push plate 207 to push the cable out of the cylindrical shell.
