Description

Technical Field

[0001] The present invention relates to the technical field of cable production, and specifically to a production device for a composite cable core. Background Art

[0002] A cable is a commonly used power transmission device, generally composed of multiple strands of wires, with a rubber cortex on the outer layer for protection. According to specific needs, it is divided into various cables such as power cables and signal cables. For better power transmission, cables are usually composite, formed by twisting multiple strands of wires together. An insulated cable refers to a cable in which the conductor is 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 electricity or signals.

[0003] The core of an 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. Since the length of the cable is relatively long during the production process, when the cable core passes through the extruder, due to the overly long exposed length, the cable core itself will shake. Moreover, when the cable core just comes out of the extruder, the insulating layer on its surface has not completely cooled and solidified, and it will cause the failure of the formation of the protective layer due to shaking and hitting the inner wall of the machine.

[0004] In the existing production devices for composite cable cores, a support structure is directly arranged around the cable core to protect the just-extruded core and prevent the core from hitting the inner wall of the machine. Although the support structure prevents the damage caused by the core shaking and hitting the inner wall of the machine, the insulating layer on the surface of the just-extruded core has not been completely shaped, and the direct sliding friction between the support structure and the surface of the insulating layer is more likely to scratch the insulating layer; and only a support structure is arranged inside the machine, and the core at the machine port is more likely to be scratched and damaged, and the traditional support structure cannot take care of the core at the machine port; the air with pollutants from the outside enters the machine interior and will contaminate the incompletely shaped insulating layer, reducing the production quality of the core. Summary of the Invention

[0005] (I) Technical Problems to be Solved Aiming at the deficiencies of the prior art, the present invention provides a production device for a composite cable core, which solves the problems that the insulating layer on the surface of the just-extruded core has not been completely shaped, and the direct sliding friction between the support structure and the surface of the insulating layer is more likely to scratch the insulating layer; and only a support structure is arranged inside the machine, and the core at the machine port is more likely to be scratched and damaged, and the traditional support structure cannot take care of the core at the machine port; the air with pollutants from the outside enters the machine interior and will contaminate the incompletely shaped insulating layer, reducing the production quality of the core.

[0006] (2) Technical Solution To achieve the above objectives, the present invention is realized through the following technical solutions: A composite cable core production device includes an extrusion tube. One side of the extrusion tube is fixedly installed with a sleeve. A protection mechanism is provided at the output port of the sleeve. A blowing mechanism is provided on one side inside the sleeve. The surface of the sleeve is threadedly connected with a mounting ring. A support mechanism is provided inside the mounting ring. The cable core is extruded through an extruder and the extrusion tube. The extruded cable core with an insulating layer enters the sleeve and sequentially passes through the support mechanism and the protection mechanism, and finally is extruded from the sleeve to form. The middle section of the core is supported by the support mechanism, the core located at the port of the sleeve is supported and protected by the protection mechanism, and the surface insulating layer of the just-extruded core can be cooled by the blowing mechanism. At the same time, the blowing mechanism can reduce the entry of external polluted air; The protection mechanism includes arc-shaped curved plates. A plurality of arc-shaped curved plates are evenly and symmetrically distributed around the center of the sleeve. Both sides of the arc-shaped curved plate are rotatably connected with sector plates. One side of the sector plate is rotatably connected with a slider. A chute is opened on the inner wall of the sleeve. The slider is slidably connected inside the chute. A guide rod is fixedly connected inside the chute. The slider is slidably connected to the surface of the guide rod. A first tight spring is elastically connected between the arc-shaped curved plate and the inner wall of the sleeve. Through the protection mechanism, cores with different diameters can be supported and protected, preventing the core with the just-wrapped insulating layer from shaking strongly and rubbing or hitting the port of the sleeve and being damaged, improving the production quality of the core; The blowing mechanism includes a micro air pump. The micro air pump is fixedly connected to the top of the sleeve. The output end of the micro air pump is connected with a connecting pipe through a pipe. The output end of the connecting pipe passes through the top wall of the sleeve and is connected with an arc-shaped pipe through a pipe. Both ends of the arc-shaped pipe are connected with a through pipe through a pipe. One side of the through pipe is connected with a blowing pipe through a pipe. Through the blowing mechanism, the surface of the extruded core can be quickly cooled, improving the smoothness of the core surface, and reducing the entry of external pollutants, preventing dust from adhering to its surface, and improving the production quality of the core.

[0007] Preferably, a limiting block is fixedly connected inside the chute. The limiting block is located in the middle of the chute. Through the limiting block, the sector plates on both sides can be prevented from sliding to the same side of the chute, ensuring the support effect of the sector plates and the arc-shaped curved plates.

[0008] Preferably, second springs are sleeved on both outer sides of the guide rod. The second springs are located on the side away from the limiting block. Through the setting of the second springs, the slider can be pushed to move in the chute, so that the slider can drive the sector plate to move left and right, and then the gap through which the core passes can be adaptively enlarged or reduced according to the diameter of the core, so as to be applicable to cores with different diameters to pass through.

[0009] Preferably, filter holes are provided on the surface of the fan-shaped plate. Since the insulation layer has just been extruded from the surface of the wire core and the insulation layer just coming out of the front side of the sleeve has not yet completely solidified, the unsolidified insulation layer has a certain adsorption capacity, 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 later. By providing small holes in the fan-shaped plate, the fan-shaped plate can play a filtering function, preventing pollutants in the outside air from entering the inside of the sleeve and contaminating the surface of the wire core, thereby improving the production quality of the wire core.

[0010] Preferably, the support mechanism comprises a fixing frame, and a plurality of the fixing frames are evenly and symmetrically distributed around the center of the sleeve, and a supporting ball is rotatably connected inside the fixing frame.

[0011] Preferably, two sides of the fixed frame are fixedly connected with rotating shafts, and the surfaces of the rotating shafts are rotatably connected with telescopic blocks.

[0012] Preferably, a telescopic sleeve is commonly provided between two adjacent telescopic blocks, and an elastic telescopic rod is commonly fixedly connected between the bottom of the telescopic sleeve and the inner wall of the sleeve, and the support wire core is contacted through the support ball in the fixed frame, and is supported by the elastic telescopic rod and the telescopic sleeve, and the fixed frames on both sides are connected by the telescopic blocks. When wire cores of different diameters pass through the supporting mechanism, they are telescoped by the elastic telescopic rod, and at the same time, the telescopic rod is telescoped in the telescopic sleeve, thereby being able to change the gap between the multiple support balls as a whole, so as to adapt to the passage of wire cores of different diameters.

[0013] Preferably, one side of the telescopic block is fixedly connected to a limit plate, and the limit plate is slidably connected to the inside of the telescopic sleeve. The limit plate is used to prevent one side of the telescopic block from escaping from the inside of the telescopic sleeve, thereby ensuring the stability of the device when in use.

[0014] Preferably, a telescopic spring is provided inside the telescopic sleeve, and both ends of the telescopic spring are fixedly connected to the surface of the limit plate. The telescopic blocks on both sides can be telescoped through the telescopic spring, thereby being able to pull the support balls on both sides closer or farther away, and then the internal space surrounded by multiple support balls can be changed as a whole, so that it can be suitable for wire cores of different diameters to pass through, thereby improving the flexibility of the equipment when in use.

[0015] (III) Beneficial effects The present invention provides a composite cable core production device having the following beneficial effects: (1) The composite cable core production equipment can protect the core at the machine port by setting a protective mechanism to prevent the core from shaking and being scratched by the machine port, thereby improving the quality of the core during production. In addition, the protective mechanism can support and protect cores of different diameters, thereby improving the flexibility of the equipment during use.

[0016] (2) The production equipment for the composite cable core can support the middle section of the core through the setting of the support mechanism. By the form of using support balls to contact and convey the core, the traditional sliding friction is transformed into rolling friction. At the same time, the contact area between the support mechanism and the core is reduced, the friction between the support mechanism and the core is lowered, the possibility of the support mechanism scratching the insulation layer of the core is decreased, the production quality of the cable core is improved, and cores with different diameters can be supported, enhancing the practicality of the equipment.

[0017] (3) The production equipment for the composite cable core can quickly cool the surface of the extruded core through the air-blowing mechanism, improve the smoothness of the core surface, reduce the entry of external pollutants into the machine and contamination of the insulation layer, improve the production quality of the core. Moreover, the rapid cooling and shaping of the insulation layer on the core surface can increase the hardness of the insulation layer, making it less likely to be scratched by the support mechanism, thus improving the production quality of the cable core.

[0018] (4) The production equipment for the composite cable core, through the cooperation of the sector plate with small holes and the air-blowing mechanism, can block the entry of air with pollutants from the outside to a certain extent into the machine interior, enabling the sector plate to function as a filter to prevent pollutants in the outside air from entering the inside of the sleeve and contaminating the core. At the same time, by blowing air through the air pipe facing the port, it makes it more difficult for outside air to enter the interior of the machine, further preventing pollutants in the air from adhering to the unfixed insulation layer, and improving the overall production quality of the core.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figure 1-8 , the present invention provides a technical solution: a composite cable core production device, the structure of which includes an extrusion tube 1, a sleeve 2 is fixedly installed on one side of the extrusion tube 1, a protection mechanism 3 is arranged at the output port of the sleeve 2, a blowing mechanism 4 is arranged on one side inside the sleeve 2, an installation ring 5 is threadedly connected to the surface of the sleeve 2, and a support mechanism 6 is arranged inside the installation ring 5. The cable core is extruded through an extruder and the extrusion tube 1, and the extruded cable core with an insulating layer enters the sleeve, and sequentially passes through the support mechanism 6 and the protection mechanism 3, and finally is extruded from the sleeve 2 to form. The middle section of the core is supported by the support mechanism 6, the core located at the port of the sleeve 2 is supported and protected by the protection mechanism 3, and the surface insulating layer of the just-extruded core can be cooled by the blowing mechanism 4, and at the same time, the blowing mechanism 4 can be used to reduce the entry of external polluted air; The protection mechanism 3 includes an arc-shaped curved plate 31, a plurality of arc-shaped curved plates 31 are evenly and symmetrically distributed around the center of the sleeve 2, sector plates 32 are rotatably connected to both sides of the arc-shaped curved plate 31, a slide block 33 is rotatably connected to one side of the sector plate 32, a chute 34 is opened on the inner wall of the sleeve 2, the slide block 33 is slidably connected to the inside of the chute 34, a guide rod 35 is fixedly connected to the inside of the chute 34, the slide block 33 is slidably connected to the surface of the guide rod 35, and a first tension spring 36 is elastically connected between the arc-shaped curved plate 31 and the inner wall of the sleeve 2; The blowing mechanism 4 includes a micro air pump 41, the micro air pump 41 is fixedly connected to the top of the sleeve 2, the output end of the micro air pump 41 is connected to a connecting pipe 42 through a pipe, the output end of the connecting pipe 42 passes through the top wall of the sleeve 2 and is connected to an arc-shaped pipe 43 through a pipe, both ends of the arc-shaped pipe 43 are connected to a through pipe 44 through a pipe, and a blowing pipe 45 is connected to one side of the through pipe 44 through a pipe.

[0023] Among them, a limiting block 37 is fixedly connected inside the sliding groove 34. The limiting block 37 is located in the middle of the sliding groove 34. Through the limiting block 37, the sector plates 32 on both sides can be prevented from sliding to the same side of the sliding groove 34, ensuring the supporting effect of the sector plates 32 and the arc-shaped curved plate 31.

[0024] Among them, two second springs 38 are sleeved on the outer sides of the guide rod 35. The second springs 38 are located on the side far from the limiting block 37. Through the arrangement of the second springs 38, the slider 33 can be pushed to move in the sliding groove 34, so that the slider 33 can drive the sector plate 32 to move left and right, and then the gap through which the wire core passes can be adaptively enlarged or reduced according to the diameter of the wire core.

[0025] Among them, filter holes 39 are formed on the surface of the sector plate 32. Since the insulating layer has just been extruded on the surface of the wire core and the insulating layer just coming out from the front side of the sleeve 2 has not completely solidified, the non-solidified insulating layer has a certain adsorption property, making 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 stage. By providing small holes on the sector plate 32, the sector plate 32 functions as a filter to prevent pollutants in the external air from entering the inside of the sleeve 2 and contaminating the surface of the wire core.

[0026] Among them, the supporting mechanism 6 includes a fixed frame 61. A plurality of fixed frames 61 are evenly and symmetrically distributed around the center of the sleeve 2. A supporting ball 62 is rotatably connected inside the fixed frame 61.

[0027] Among them, two rotating shafts 63 are fixedly connected to both sides of the fixed frame 61. A telescopic block 64 is rotatably connected to the surface of the rotating shaft 63.

[0028] Among them, a telescopic sleeve 65 is jointly sleeved between two adjacent telescopic blocks 64. An elastic telescopic rod 66 is jointly fixedly connected between the bottom of the telescopic sleeve 65 and the inner wall of the sleeve 2.

[0029] Specifically, the wire core is supported by the supporting ball 62 in the fixed frame 61, and the elastic telescopic rod 66 and the telescopic sleeve 65 are used for support. The telescopic blocks 64 are used to connect the two fixed frames 61 on both sides. When wire cores with different diameters pass through the supporting mechanism 6, the elastic telescopic rod 66 expands and contracts, and at the same time, the telescopic rod expands and contracts in the telescopic sleeve 65, so that the gap between multiple supporting balls 62 can be changed as a whole, thus adapting to wire cores with different diameters passing through.

[0030] Among them, a limiting plate 67 is fixedly connected to one side of the telescopic block 64. The limiting plate 67 is slidably connected inside the telescopic sleeve 65, and the limiting plate 67 is used to prevent one side of the telescopic block 64 from separating from the inside of the telescopic sleeve 65.

[0031] Among them, a telescopic spring 68 is arranged inside the telescopic sleeve 65, and both ends of the telescopic spring 68 are fixedly connected to the surface of the limit plate 67. The telescopic blocks 64 on both sides can be telescoped through the telescopic spring 68, so as to pull the distance between the supporting balls 62 on both sides closer or farther, and then the internal space surrounded by multiple supporting balls 62 can be changed as a whole.

[0032] During operation: when wrapping the cable core with an insulating layer, the cable core is extruded through the extruder and the extrusion tube 1, the extruded cable core with the insulating skin enters the sleeve, and passes through the supporting mechanism 6 and the protective mechanism 3 in sequence, and finally extruded into the sleeve 2 for forming; The protective mechanism 3 can prevent the cable core from shaking in the sleeve 2 and hitting the port of the sleeve 2, and prevent the cable core from hitting the port and damaging the insulation layer. The arc-shaped curved plate 31 and the fan-shaped plates 32 on both sides can support the core, and the first spring can press the core toward the center of the circle. When it is necessary to support and press the cores of different diameters, the fan-shaped plates 32 on both sides are moved away from opening or moved closer to closing, so that the slider 33 slides left and right along the guide rod 35 inside the slide groove 34, and the fan-shaped plates 32 on both sides drive the arc-shaped curved plates 31 to expand and contract, and then the size of the gap between the multiple arc-shaped curved plates 31 changes, so that cores of different diameters can pass through. The setting of the protective mechanism 3 can support and protect the cores of different diameters, prevent the cores of the newly wrapped insulation layer from shaking strongly and being damaged by rubbing or colliding with the port of the sleeve 2, thereby improving the production quality of the core; The blowing mechanism 4 can not only cool the insulating layer on the surface of the just-extruded wire core, but also blow air toward the output port of the sleeve 2, further preventing the outside air with pollutants from entering the inside of the sleeve 2. When the blowing mechanism 4 is working, the micro air pump 41 with its own filtering function is first started to blow air, and the filtered gas enters the inside of the arc tube 43 through the connecting tube 42, and then enters the through pipe 44, and finally passes through the blowing tube 45 vertically to the surface of the wire core, thereby achieving the purpose of quickly cooling the insulating layer on the surface of the just-extruded wire core, and because the blowing tube 45 is inclined, it is toward the output end of the sleeve 2, thereby reducing the outside air from entering from the output port of the sleeve 2, and the blowing mechanism 4 can quickly cool the surface of the extruded wire core, improve the smoothness of the surface of the wire core, and reduce the entry of external pollutants, prevent dust from adhering to its surface, and improve the quality of wire core production; Since the sleeve 2 is slightly longer, the middle section of the wire core is supported by the support mechanism 6. And the insulating layer on the surface of the middle-section wire core has just been cooled by the wind and is not as thoroughly cooled as the port of the sleeve 2. Therefore, it is supported by the rolling of the support balls 62 in the support mechanism 6, reducing the contact area between the support mechanism 6 and the wire core. And by changing the traditional sliding friction into rolling friction, the frictional force between the support mechanism 6 and the surface of the wire core is reduced. Furthermore, the extrusion of the traditional support mechanism 6 on the wire core is reduced and even damage is avoided. When the support mechanism 6 supports the wire core, the wire core is supported by the contact of the support balls 62 in the fixed frame 61, and is supported by the elastic telescopic rod 66 and the telescopic sleeve 65. The two sides of the fixed frame 61 are connected by the telescopic block 64. When wire cores of different diameters pass through the support mechanism 6, the elastic telescopic rod 66 expands and contracts, and at the same time the telescopic rod expands and contracts in the telescopic sleeve 65, so that the gap between multiple support balls 62 can be changed as a whole, thus being able to adapt to wire cores of different diameters passing through. The limiting plate 67 is used to prevent one side of the telescopic block 64 from separating from the inside of the telescopic sleeve 65, and the telescopic spring 68 enables the telescopic blocks 64 on both sides to expand and contract, so that the distance between the support balls 62 on both sides can be pulled in or widened, and thus the internal space surrounded by multiple support balls 62 can be changed as a whole.
