Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable production, in particular to a composite cable core production equipment. BACKGROUND

[0002] The cable is a commonly used power transmission device, generally composed of multiple wires, and the outer layer is wrapped with a rubber skin layer for protection. According to specific needs, it is divided into power cables, signal cables and various cables. In order to better transmit power, the cable is usually composite, and the multiple wires are twisted together. The insulated cable refers to a cable wrapped with an insulating material to prevent current leakage or short circuit. The insulating layer not only protects the conductor from environmental influences such as moisture and chemical corrosion, but also ensures the safe transmission of power or signals.

[0003] The core of the insulated cable must be wrapped with an insulating layer, which is a basic requirement for electrical safety. Therefore, when producing the core of such a cable, an extruder is needed to coat the surface of the core with an insulating layer. Due to the relatively long length of the cable during production, the cable core will sway when passing through the extruder due to the excessive length exposed to the outside. Moreover, since the insulating layer on the surface of the cable core has not completely cooled and solidified when it comes out of the extruder, the protective layer may fail to form due to the sway and impact on the inner wall of the machine.

[0004] The existing composite cable core production equipment directly sets a support structure around the cable core to protect the freshly extruded core from impacting the inner wall of the machine. Although the support structure prevents the cable core from swaying and damaging the inner wall of the machine, the freshly extruded core surface insulating layer has not completely set, and the direct sliding friction between the support structure and the surface of the insulating layer is more likely to scratch the insulating layer. Moreover, only setting the support structure inside the machine, the cable core at the port of the machine is more likely to be scratched and damaged. The traditional support structure cannot take care of the cable core at the port of the machine. The air with pollutants from the outside entering the machine interior will contaminate the insulating layer that has not completely set, reducing the production quality of the core. SUMMARY

[0005] (I) Technical problems solved

[0006] In view of the deficiencies of the prior art, the present application provides a composite cable core production equipment, which solves the problems of the freshly extruded core surface insulating layer not being completely set, the direct sliding friction between the support structure and the surface of the insulating layer being more likely to scratch the insulating layer, and the cable core at the port of the machine being more likely to be scratched and damaged by the traditional support structure that cannot take care of the cable core at the port of the machine. The air with pollutants from the outside entering the machine interior will contaminate the insulating layer that has not completely set, reducing the production quality of the core.

[0007] (II) Technical solutions

[0008] In order to achieve the above object, the present application is realized by the following technical scheme: a composite cable core production equipment, comprising an extrusion pipe, a sleeve is fixedly installed on one side of the extrusion pipe, a protection mechanism is arranged at the outlet of the sleeve, a blowing mechanism is arranged at the inside of the sleeve, an installation ring is screw-connected to the surface of the sleeve, a supporting mechanism is arranged in the inside of the installation ring, the cable core is extruded through the extruder and the extrusion pipe, the extruded cable core with the insulating skin enters the sleeve and passes through the supporting mechanism and the protection mechanism in turn, and finally the extruded sleeve is formed, the middle section of the cable core is supported by the supporting mechanism, the cable core at the port of the sleeve is supported and protected by the protection mechanism, and the surface insulating layer of the just extruded cable core can be cooled by the blowing mechanism, and the entry of the external polluted air can be reduced by the blowing mechanism;

[0009] The protection mechanism comprises a plurality of arc-shaped curved plates which are uniformly and symmetrically distributed around the center of the sleeve, a fan-shaped plate is rotatably connected to the two sides of the arc-shaped curved plate, a sliding block is rotatably connected to one side of the fan-shaped plate, a sliding groove is formed in the inner wall of the sleeve, the sliding block is slidingly connected in the inside of the sliding groove, a guide rod is fixedly connected in the inside of the sliding groove, the sliding block is slidingly connected to the surface of the guide rod, and a first tension spring is elastically connected between the arc-shaped curved plate and the inner wall of the sleeve, the cable core of different diameters can be supported and protected by the protection mechanism, the just wrapped cable core is prevented from shaking strongly and being damaged by scratching or impacting the port of the sleeve, and the production quality of the cable core is improved;

[0011] Preferably, a limiting block is fixedly connected in the inside of the sliding groove, and the limiting block is located in the middle of the sliding groove, the limiting block can prevent the fan-shaped plates on the two sides from sliding to the same side of the sliding groove, and the supporting effect of the fan-shaped plates and the arc-shaped curved plates is ensured.

[0012] Preferably, the outer two sides of the guide rod are sleeved with a second spring, which is located away from the limiting block. The second spring can push the sliding block to move in the sliding groove, so that the sliding block drives the sector plate to move left and right, and the gap through which the wire core passes can be self-adaptively enlarged or reduced according to the size of the wire core diameter, so as to be suitable for wire cores of different diameters.

[0013] Preferably, the surface of the sector plate is provided with filter holes. Since the wire core surface is just extruded with an insulation layer, the insulation layer on the front side of the sleeve has not completely solidified, so that the un-solidified insulation layer has a certain adsorption property, which makes it easier for pollutants to adhere to its surface, and it is not easy to clean the pollutants on the surface of the wire core in the later period. By providing small holes in the sector plate, the sector plate plays a filtering function, preventing pollutants in the external air from entering the inside of the sleeve and polluting the surface of the wire core, and improving the production quality of the wire core.

The support ball in the fixed frame contacts and supports the wire core, and the elastic expansion rod and the expansion sleeve are used for support. The expansion blocks are used to connect the fixed frames on both sides. When wire cores of different diameters pass through the support mechanism, the elastic expansion rod expands and contracts, and the expansion rod expands and contracts in the expansion sleeve, so that the gap between the plurality of support balls can be changed as a whole, thereby adapting to wire cores of different diameters.

[0017] Preferably, one side of the expansion block is fixedly connected with a limiting plate, and the limiting plate is slidably connected in the inside of the expansion sleeve.

[0022] (2) The composite cable core production equipment can support the middle section of the cable core through the support mechanism, and convert traditional sliding friction into rolling friction by contacting and conveying the cable core through the support ball, while reducing the contact area between the support mechanism and the cable core, reducing the friction between the support mechanism and the cable core, reducing the possibility of the support mechanism scratching the insulation layer of the cable core, improving the production quality of the cable core, and supporting the cable core of different diameters, improving the practicability of the equipment.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0035] Referring to Figures 1-8 The application provides a technical solution: a composite cable core production equipment, which comprises an extrusion pipe 1, a sleeve 2 fixedly installed on one side of the extrusion pipe 1, a protection mechanism 3 arranged at an output port of the sleeve 2, a blowing mechanism 4 arranged at one side in the interior of the sleeve 2, a mounting ring 5 threadedly connected to the surface of the sleeve 2, and a supporting mechanism 6 arranged in the interior of the mounting ring 5. The cable core is extruded through an extruder and the extrusion pipe 1, the extruded cable core with an insulating skin enters the sleeve, and sequentially passes through the supporting mechanism 6 and the protection mechanism 3, and finally is formed by the extrusion sleeve 2. The supporting mechanism 6 supports the middle section of the core, the protection mechanism 3 supports and protects the core at the port of the sleeve 2, and the blowing mechanism 4 can cool the surface insulating layer of the just extruded core, and simultaneously reduce the entry of external polluted air by using the blowing mechanism 4.

[0036] ​The protection mechanism 3 comprises arc curved plates 31 which are uniformly and symmetrically distributed around the center of the sleeve 2, both sides of the arc curved plate 31 are rotationally connected with a sector plate 32, one side of the sector plate 32 is rotationally connected with a sliding block 33, the inner wall of the sleeve 2 is provided with a sliding groove 34, the sliding block 33 is slidingly connected in the sliding groove 34, the inner wall of the sliding groove 34 is fixedly connected with a guide rod 35, the sliding block 33 is slidingly connected with the surface of the guide rod 35, the arc curved plate 31 and the inner wall of the sleeve 2 are jointly and elastically connected with a first tight spring 36.

[0037] The blowing mechanism 4 comprises a micro air pump 41 which is fixedly connected to the top of the sleeve 2, the output end of the micro air pump 41 is connected with a connecting pipe 42, the output end of the connecting pipe 42 penetrates through the top wall of the sleeve 2 and is connected with an arc-shaped pipe 43, both ends of the arc-shaped pipe 43 are connected with a through pipe 44, one side of the through pipe 44 is connected with a blowing pipe 45.

[0038] The inner wall of the sliding groove 34 is fixedly connected with a limiting block 37, the limiting block 37 is located in the middle of the sliding groove 34, the limiting block 37 can prevent the two sector plates 32 from sliding to the same side of the sliding groove 34, thereby ensuring the supporting effect of the sector plate 32 and the arc curved plate 31.

[0039] The outer sides of the guide rod 35 are sleeved with a second spring 38, the second spring 38 is located on the side away from the limiting block 37, the second spring 38 can push the sliding block 33 to move in the sliding groove 34, so that the sliding block 33 drives the sector plate 32 to move left and right, thereby the gap through which the wire core passes can be self-adaptively enlarged or reduced according to the diameter of the wire core.

[0040] The surface of the sector plate 32 is provided with a filter hole 39, because the wire core surface is just extruded with an insulation layer, the insulation layer just coming out of the front side of the sleeve 2 has not completely solidified, so that the un-solidified insulation layer has a certain adsorption, which is more easy to make the pollutants adhere to its surface, and the pollutants on the surface of the wire core are not easy to clean in the later period, by providing the sector plate 32 with a small hole, the sector plate 32 plays a filtering function, preventing the pollutants in the external air from entering the inside of the sleeve 2 to pollute the surface of the wire core.

[0041] The supporting mechanism 6 comprises a fixed frame 61 which is uniformly and symmetrically distributed around the center of the sleeve 2, the inner wall of the fixed frame 61 is rotationally connected with a supporting ball 62.

[0042] The two sides of the fixed frame 61 are fixedly connected with a rotating shaft 63, the surface of the rotating shaft 63 is rotationally connected with an extension block 64.

[0043] The adjacent two extension blocks 64 are jointly sleeved with an extension sleeve 65, the bottom of the extension sleeve 65 and the inner wall of the sleeve 2 are jointly and fixedly connected with an elastic extension rod 66.

[0044] Specifically, the support balls 62 in the fixed frame 61 contact the support wire core, and are supported by the elastic expansion rod 66 and the expansion sleeve 65, and the expansion blocks 64 are connected to the two sides of the fixed frame 61. When the wire core with different diameters passes through the support mechanism 6, the elastic expansion rod 66 is expanded, and the expansion rod is expanded in the expansion sleeve 65, so that the gap between the plurality of support balls 62 can be changed as a whole, so that the wire core with different diameters can pass through.

[0045] One side of the expansion block 64 is fixedly connected with a limiting plate 67, and the limiting plate 67 is slidably connected in the inside of the expansion sleeve 65. The limiting plate 67 prevents the one side of the expansion block 64 from being separated from the inside of the expansion sleeve 65.

[0046] The inside of the expansion sleeve 65 is provided with an expansion spring 68, and the two ends of the expansion spring 68 are fixedly connected to the surface of the limiting plate 67. The expansion spring 68 can make the two expansion blocks 64 expand, so that the distance between the two support balls 62 can be pulled in or away, and the inside space surrounded by the plurality of support balls 62 can be changed as a whole.

[0047] When working: when the cable core is wrapped with an insulation layer, the cable core passes through the extruder and the extrusion pipe 1, the extruded cable core with an insulation layer enters the sleeve, and sequentially passes through the support mechanism 6 and the protection mechanism 3, and finally the extrusion sleeve 2 is formed;

[0048] The protection mechanism 3 can prevent the cable core from shaking in the sleeve 2 and colliding with the port of the sleeve 2, prevent the cable core from colliding with the port and damaging the insulation layer, and the arc-shaped curved plate 31 and the two fan-shaped plates 32 can support the wire core, and the wire core is tightly pressed to the center by the first spring. When the wire core with different diameters needs to be supported and tightly pressed, the two fan-shaped plates 32 are away from each other or close to each other, so that the slider 33 slides left and right in the inside of the sliding groove 34 along the guide rod 35, the two fan-shaped plates 32 drive the arc-shaped curved plate 31 to expand, and the gap between the plurality of arc-shaped curved plates 31 changes, so that the wire core with different diameters can pass through. The setting of the protection mechanism 3 can support the wire core with different diameters, prevent the wire core with the insulation layer from shaking strongly and scratching or colliding with the port of the sleeve 2, and improve the production quality of the wire core;

[0049] The blowing mechanism 4 can cool the insulation layer of the just-extruded core surface and blow air to the outlet of the sleeve 2, further preventing the outside air with pollutants from entering the inside of the sleeve 2. When the blowing mechanism 4 works, the micro air pump 41 with a filtering function is started to blow air first. The filtered air enters the arc-shaped pipe 43 through the connecting pipe 42, then enters the through pipe 44, and finally vertically blows to the surface of the core through the blowing pipe 45, so as to quickly cool the insulation layer of the just-extruded core surface. Since the blowing pipe 45 is inclined and faces the outlet of the sleeve 2, the outside air entering from the outlet of the sleeve 2 is reduced. The blowing mechanism 4 can quickly cool the extruded core surface, improve the smoothness of the core surface, reduce the entry of external pollutants, prevent dust from adhering to the surface, and improve the quality of the core production.

[0050] Since the sleeve 2 is slightly long, the middle section of the core is supported by the supporting mechanism 6, and the insulation layer on the surface of the middle section of the core is not cooled as completely as the port of the sleeve 2. The supporting mechanism 6 supports the core in a rolling manner through the supporting balls 62, reduces the contact area between the supporting mechanism 6 and the core, and changes the traditional sliding friction to rolling friction, thereby reducing the friction between the supporting mechanism 6 and the core surface and reducing the extrusion of the traditional supporting mechanism 6 on the core. When the supporting mechanism 6 supports the core, the supporting balls 62 in the fixed frame 61 contact and support the core, and the elastic extension rod 66 and the extension sleeve 65 are used for support. The extension block 64 connects the two fixed frames 61. When the core with different diameters passes through the supporting mechanism 6, the elastic extension rod 66 extends and retracts in the extension sleeve 65, so that the gap between the multiple supporting balls 62 can be changed as a whole, thereby adapting to the core with different diameters. The limiting plate 67 prevents one side of the extension block 64 from separating from the inside of the extension sleeve 65, and the extension spring 68 can make the two extension blocks 64 extend and retract, so that the distance between the two supporting balls 62 can be pulled in or away, thereby changing the internal space surrounded by the multiple supporting balls 62 as a whole.
