Description

Technical Field

[0001] This invention relates to the field of cable production technology, and in particular to a cable core coating and molding device for the production of civilian cables. Background Technology

[0002] The cable core is the conductive part of a power cable, used to transmit electrical energy. It is the main part of the power cable. Currently, copper or aluminum is generally used for the cable core. Polyethylene is a thermoplastic plastic polymerized from ethylene. It has good electrical insulation properties, but low heat resistance and mechanical strength. By chemically or irradiating crosslinking polyethylene, the polyethylene molecular chains form a three-dimensional network structure. When processing crosslinked polyethylene cables, a layer of crosslinked polyethylene material needs to be wrapped around the cable core to achieve insulation. This requires the use of a coating molding device.

[0003] If the core temperature is too low during the overmolding process, the extruded molten material will cool and solidify rapidly when it comes into contact with the core, resulting in insufficient adhesion and affecting the quality of the produced cable.

[0004] To address this, the patent application CN115050523A, titled "A Cable Core Coating and Molding Device for Cable Production," describes a device that uses a heater to heat a pair of preheating tubes. The wire core passes through the preheating tubes before entering the hollow rod, thus achieving the purpose of preheating the wire core. This solves the problem that when the wire core temperature is too low during coating and molding, the extruded molten material cools down rapidly when it comes into contact with the wire core, resulting in insufficient adhesion and separation of the inner and outer layers of the cable.

[0005] However, in the actual processing, heating with a heater will result in a lot of energy consumption. Also, since the surface of the cable core will be covered with dust, impurities and oxide layer, if the dust on the surface of the cable core is not cleaned in advance, the adhesion between the cable core and the sheathing material will be affected, thus affecting the quality of the produced cable. Summary of the Invention

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1: Please refer to Figures 1 to 9 This invention provides a technical solution: a cable core coating molding device for civilian cable production, comprising a mounting frame 1, an extrusion assembly 2 for extruding coating material mounted on the inner side of the mounting frame 1, an extrusion cylinder 3 mounted on the bottom of the extrusion assembly 2, the cable core being inserted into the extrusion cylinder 3, a cooling assembly 4 for cooling the coating material mounted on the left side of the mounting frame 1, and a pretreatment assembly 5 disposed on the right side of the mounting frame 1, the pretreatment assembly 5 being used for preheating the cable core and cleaning its surface, the pretreatment assembly 5 including a frame 51 fixed to the right side of the mounting frame 1, the frame 51... The internal moving parts include a water spray frame 52, and a cleaning frame 53. Brush bristles are fixed inside the cleaning frame 53. A pipe 54 connected to the cooling component 4 is fixedly inserted into the bottom of the water spray frame 52. The pipe 54 is used to input the heated water into the interior of the water spray frame 52. A spray pipe 55 is fixedly inserted into the inner side of the pipe 54. A heating box 510 is configured in the middle part of the pipe 54. A heating element for heating is installed inside the heating box 510. A drainage groove 59 is opened at the bottom of the frame 51. A liquid pump is installed inside the pipe 54 to allow water to enter the interior of the water spray frame 52.

[0045] By adopting the above technical solution, the extrusion component 2 uses a screw extruder, which is a mature existing technology and will not be described in detail. The cooling component 4 includes a cooling cylinder through which the cable core passes. A cold water pipe for cooling water is inserted into the top of the cylinder. After entering the cylinder, the cold water pipe can branch into multiple branches, which spray cold water evenly onto the cross-linked polyethylene material from different directions from different angles to cool the material. This cooling technology is a mature existing technology and will not be described in detail. When the device is in use, the cable core is passed through the extrusion cylinder 3, the pretreatment component 5, and the cooling component 4, and the cable core is pulled at the left end. The pulling technology is a mature existing technology and will not be described in detail.

[0046] During the coating process, the required cross-linked polyethylene material is placed inside the extrusion assembly 2. The cross-linked polyethylene material is melted and extruded into the extrusion cylinder 3 through the extrusion assembly 2 to coat the cable core. As the cable core is pulled, the surface of the cable core can be uniformly coated.

[0047] Before the cable core is covered, the cable core is pretreated by the pretreatment component 5. After the covering material is cooled and absorbs heat, hot water enters the interior of the spray frame 52 through the pipe 54, and then sprays onto the ring side of the cable core through multiple spray pipes 55. In this way, the cooled water is used to preheat the cable core, increase the temperature of the cable core during the covering process, and reduce the situation where the molten material cools down and solidifies rapidly when it is bonded to the cable core, resulting in insufficient adhesion. At the same time, the warm water generated after the cooling water absorbs heat is used to preheat the cable core, reducing energy consumption during preheating.

[0048] It should be noted that a collection box is set at the bottom of the frame 51. The water used for preheating is sprayed onto the cable core and then discharged from the drain trough 59 and enters the collection box. The pipe 54 near the water spray frame 52 is made of a flexible pipe.

[0049] As the cable moves due to traction, the cable core moves, causing relative movement between the cable core and the brush bristles. This cleans impurities from the surface of the cable core, removing dust and other contaminants. This reduces the impact of dust on the adhesion between the cable core and the sheathing material, improving the tightness between the sheathing material and the cable core, and ultimately enhancing the quality of the produced cable.

[0050] The sprayed water, combined with the brush bristles, cleans the cable core, improving the cleaning effect and further enhancing the tightness between the sheathing material and the cable core, thus improving the quality of the produced cable.

[0051] In the initial processing state, since no hot coating material has entered the cooling component 4, the water temperature used for preheating is low. The water is heated by the heating element inside the heating box 510. The heating element can be an electric heating wire, which is a mature existing technology and will not be described in detail.

[0052] A moving frame 56 is fixed to the left side of the cleaning frame 53. The surface of the moving frame 56 has a spiral groove. A fixing tube 58 is fixed inside the left side of the frame 51. A guide slider 57 that moves within the spiral groove is fixed inside the fixing tube 58. The left side of the moving frame 56 moves within the fixing tube 58. A transmission assembly 6 for driving the water spray frame 52 is provided on the right side. A sliding groove 10 is provided on the cleaning frame 53 corresponding to the position of the spray pipe 55. The transmission assembly 6 includes a mounting box 61 fixed to the mounting bracket 1 located on the right side of the frame 51. Both the top and bottom ends of the inner side are rotatably connected to extrusion rollers 62. The upper extrusion roller 62 is slidable. The front and rear ends of the central axis of the lower extrusion roller 62 pass through the frame 51 and are fixedly connected to a disc 63. The eccentric part of the disc 63 is fixedly connected to a driving rod 64. A motion frame 65 is sleeved on the outside of the driving rod 64. The left side of the two motion frames 65 is fixedly connected to a connecting frame 66. A round rod 67 is fixedly connected between the connecting frame 66 and the frame 51. The round rod 67 slides inside the frame 51. A through groove is opened on the motion frame 56 near the cleaning frame 53.

[0053] By adopting the above technical solution, during production preparation, the cable core passes through the two extrusion rollers 62. The central axis of the upper extrusion roller 62 is rotatably connected to a slider. The slider is adjusted and controlled by rotating bolts. When the cable core is inserted, the upper extrusion roller 62 moves upward as a whole through bolt adjustment to facilitate the insertion of the cable core. When the device is in use, the upper extrusion roller 62 moves downward to achieve sufficient extrusion force on the cable core by the two extrusion rollers 62. The extrusion rollers 62 are fixedly connected with rubber anti-slip pads to ensure sufficient friction between the extrusion rollers 62 and the cable core.

[0054] In addition to dust and impurities, the surface of the cable core may also have an oxide layer. When the cable core is pulled by an external traction device, the friction between the extrusion wheel 62 and the cable core causes the extrusion wheel 62 to rotate. When the extrusion wheel 62 rotates, its central axis causes the disc 63 to rotate, which in turn causes the eccentrically mounted drive rod 64 to rotate. As the eccentrically mounted drive rod 64 rotates along the axis of the disc 63, it moves inside the motion frame 65, causing the motion frame 65 to move in the left and right directions. This causes the connecting frame 66 to reciprocate along the left and right directions with the round rod 67, which in turn causes the water spray frame 52 to reciprocate. With the spray pipe 55 inside the chute 10, the cleaning frame 53, along with its bristles, reciprocates, improving the abrasion cleaning effect of the bristles on the cable core. This effectively cleans the oxide layer and dust, further improving the removal of impurities, and ultimately increasing the tightness between the sheathing material and the cable core, thus improving the quality of the produced cable.

[0055] When the cleaning frame 53 reciprocates with the water spray frame 52, the cleaning frame 53 moves along with the moving frame 56. At this time, there is relative movement between the moving frame 56 and the fixed tube 58. Under the cooperation of the spiral groove and the guide slider 57, the moving frame 56 and the fixed tube 58 rotate, so that the cleaning frame 53 rotates inside the water spray frame 52. When the cleaning frame 53 rotates, the bristles can rotate to clean the oxide layer and dust on the cable core, further improving the cleaning effect, thereby improving the tightness between the sheathing material and the cable core, improving the quality of the produced cable, and the rotation cleaning can reduce the blind spots of cleaning and improve the comprehensiveness of cleaning.

[0056] It should be noted that the spiral groove has a large pitch and a small length, so the rotation angle of the cleaning frame 53 is small when the cleaning frame 53 reciprocates.

[0057] It should be noted that the frictional force generated between the extrusion roller 62 and the cable core is greater than the resistance when the water spray frame 52 moves.

[0058] It should be noted that the water sprayed from the nozzle 55 can rinse the bristles of the cleaning frame 53, thereby increasing the degree of bristle crystallization. The movement of the bristles can also help shake off the impurities adhering to the bristles. When the cleaning frame 53 rotates, the position of the bristles and the nozzle 55 change, which allows the nozzle 55 to rinse different positions, thereby improving the rinsing effect.

[0059] The overcoating device also includes a wiper assembly 7 disposed on the left side of the frame 51. The wiper assembly 7 includes a sleeve rod 71 fixedly connected to the left side of the motion frame 56. A through rod 72 is slidably connected to the left side of the sleeve rod 71. A ring 73 is fixedly connected to the left side of the through rod 72. A flexible wiper ring 74 is fixedly connected to the inner side of the ring 73. The wiper assembly 7 also includes a limiting frame 75 fixedly connected to the top left side of the frame 51. A limiting groove 76 is provided on the limiting frame 75 near the ring 73. The ring side of the ring 73 is located inside the limiting groove 76 near the limiting groove 76. A ball for reducing friction is rotatably connected inside the limiting groove 76.

[0060] By adopting the above technical solution, the flexible scraper ring 74 is made of flexible rubber material, which can scrape off the residual water after rinsing and preheating, avoiding affecting subsequent processing and thus avoiding affecting the quality of the produced cable.

[0061] When the motion frame 56 rotates under the action of the fixed tube 58 and the guide slider 57, the sleeve rod 71 can rotate with the through rod 72, thereby causing the ring 73 to rotate with the flexible scraper ring 74. This facilitates the scraping of water while using centrifugal force to throw out the scraped water, thus improving the scraping effect.

[0062] Under the limiting action of the limiting groove 76, the ring 73 can limit the ring 73. When the moving frame 56 rotates, it will also move left and right. At this time, the sleeve rod 71 slides with the through rod 72.

[0063] Example 2: The technical solution of this example differs from that of Example 1 in that: Figure 1 , Figure 2 , Figure 10 , Figure 11 and Figure 12 The overcoating device also includes a drying assembly 8 located to the left of the squeegee assembly 7. The drying assembly 8 includes a circular frame 81 fixedly connected to the inside of the mounting frame 1. A drying frame 82 is provided inside the circular frame 81 and rotates along the axis of the circular frame 81. A wiping section 85 is provided inside the drying frame 82. A venting frame 83 is fixedly connected to the left side of the drying frame 82. A rotating tube 84 is fixedly connected to the inside of the venting frame 83. A drive assembly 9 for driving the rotating tube 84 to rotate is provided inside the mounting frame 1. The drive assembly 9 includes a first motor fixedly connected to the inside of the mounting frame 1. Gears are fixedly connected to both the output shaft of the first motor and the outer wall of the rotating tube 84. The two gears mesh with each other. When the output shaft of the first motor rotates, the rotating tube 84 rotates under the action of the two gears. The right side of the venting frame 83 is fixedly inserted with a... A small tube 87 is connected to the dryer, and a spray hood 88 is fixedly inserted into the right side of the small tube 87. A baffle 89 is rotatably connected to the right side of the ventilation frame 83. The dryer 85 includes a pulley 851. There are two pulleys 851. One of the pulleys 851 is driven by a second motor and rotates on both sides of the drying frame 82. A drive belt 852 is connected to the outside of the pulley 851. A battery is installed on the drying frame 82 to power the second motor. A drying cotton 853 is fixedly connected to the outside of the drive belt 852. A groove is opened inside the drive belt 852. The drying assembly 8 also includes a ring cover 86 that rotates on the left side of the ventilation frame 83. An air inlet pipe 810 is fixedly inserted between the ring cover 86 and the baffle 89. An air pump is installed inside the air inlet pipe 810 to make the gas flow to the spray hood 88.

[0064] By adopting the above technical solution, after the water is scraped off, there is still some moisture remaining on the cable core, making the surface of the cable core relatively damp. Therefore, this solution designs a drying component 8. When drying, the rotating tube 84 is driven to rotate by the driving component 9, which can make the rotating tube 84 rotate along with the ventilation frame 83 and the drying frame 82. At this time, the drying cotton 853 in the drying tube 85 rotates accordingly, removing the moisture on the cable core, reducing the impact of moisture on the adhesion between the sheathing material and the cable core, and improving the quality of cable production.

[0065] As the drying frame 82 rotates with the wiping cotton 85, the second motor drives one of the pulleys 851 to rotate, causing the transmission belt 852 to carry the wiping cotton 853 in the opposite direction to the cable core, further improving the effect of removing moisture from the surface of the cable core.

[0066] Furthermore, due to the movement of the transmission belt 852, the part containing moisture after wiping with the drying cotton 853 moves to a position close to the spray hood 88. The top of the spray hood 88 has a spray hole, and the ring hood 86 is installed on the left side of the extrusion cylinder 3. The cable core that has just been wrapped passes through the ring hood 86. At this time, the air pump is started, causing the gas inside the small tube 87 to flow to the spray hood 88. The external gas enters the ring hood 86 and then enters the spray hood 88. During this process, the external air initially cools the cable core and the wrapping material. After cooling, the heat-absorbing air enters the air inlet pipe 810 and is finally sprayed out from the spray hood 88 to dry the moisture absorbed by the drying cotton 853.

[0067] It should be noted that the squeegee 7 removes more water first, while the wiping cotton 853 removes less water.

[0068] It should be noted that the ring cover 86 is initially cooled by air cooling, and the cooling component 4 is cooled by water cooling, realizing staged cooling and avoiding rapid cooling that could cause stress in the sheathing material and affect the quality of the cable.

[0069] Working principle: During the coating process, the required cross-linked polyethylene material is placed inside the extrusion assembly 2. The cross-linked polyethylene material is melted and extruded into the extrusion cylinder 3 through the extrusion assembly 2, thereby coating the cable core. As the cable core is pulled, the surface of the cable core can be uniformly coated.

[0070] Subsequently, multiple nozzles 55 spray water onto the ring side of the cable core, using the cooled water to preheat the cable core, increasing the temperature of the cable core during the sheathing process. This reduces the risk of the molten material rapidly solidifying and cooling when it comes into contact with the cable core, which could lead to insufficient adhesion. Simultaneously, the warm water generated after the cooling water absorbs heat further preheats the cable core, reducing energy loss during preheating. This allows the cable core to move, creating relative movement between the cable core and the brush bristles. This effectively cleans impurities from the cable core surface, removing dust and impurities that may affect the adhesion between the cable core and the sheathing material, improving the tightness between the sheathing material and the cable core, and ultimately improving the quality of the produced cable. The sprayed water, combined with the brush bristles, effectively cleans the cable core, further enhancing the tightness between the sheathing material and the cable core, and improving the quality of the produced cable.

[0071] When the cable core is pulled by an external traction device, the friction between the extrusion wheel 62 and the cable core causes the extrusion wheel 62 to rotate. When the lower extrusion wheel 62 rotates, its central axis causes the disc 63 to rotate, which in turn causes the eccentrically mounted drive rod 64 to rotate. As the eccentrically mounted drive rod 64 rotates along the axis of the disc 63, it moves within the moving frame 65, causing the moving frame 65 to move left and right. This causes the connecting frame 66 to reciprocate left and right along the rod 67, which in turn causes the spray frame 52 to reciprocate. With the spray pipe 55 within the chute 10, the cleaning frame 53, along with its bristles, reciprocates, improving the cleaning effect of the bristles on the cable core. This effectively removes oxide layers and dust, further improving the cleaning efficiency. To achieve a high-quality cleaning effect, the cleaning frame 53 moves along with the moving frame 56. At this time, relative movement occurs between the moving frame 56 and the fixed tube 58. Under the cooperation of the spiral groove and the guide slider 57, the moving frame 56 and the fixed tube 58 rotate, causing the cleaning frame 53 to rotate inside the water spray frame 52. When the cleaning frame 53 rotates, the bristles can rotate to clean the oxide layer and dust on the cable core, further improving the cleaning effect and thus improving the tightness between the sheathing material and the cable core. The water sprayed from the spray pipe 55 can rinse the bristles of the cleaning frame 53, thereby improving the crystallization degree of the bristles. The movement of the bristles can also help shake off the impurities adhering to the bristles. When the cleaning frame 53 rotates, the position of the bristles and the position of the spray pipe 55 change, which facilitates the spray pipe 55 to rinse different positions, thereby improving the rinsing effect.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
