Description

Technical Field

[0001] The invention relates to the technical field of cable processing, in particular to a cable sheath coating production equipment. Background Art

[0002] The structure of coaxial cable is that the conductor used for transmitting signals is located in the center, and the conductor is covered with an insulating layer, an aluminum tube layer and a sheath from the inside to the outside. The last production process of coaxial cable is to cover the core wire with a sheath after cabling to protect the core wire from the external environment when in use. The operation method of covering the sheath is: the core wire is pulled through the mold cavity of the sheathing machine head, and the mold cavity contains a molten plastic material, which is evenly coated on the outer surface of the aluminum tube layer of the core wire, and then enters the water tank to cool and shape the coated sheath. Cables buried underground lack certain protection. If the protection is not in place, it is difficult to repair the cable once it is damaged. Sheaths are often installed on cables buried underground to prevent the cables from experiencing various wear and corrosion in the underground environment. The impact on power supply caused by the corrosion. The Chinese patent announcement number is: CN113450975B discloses "A cable wear-resistant and corrosion-resistant sheath and its covering device". This patent improves the waterproof penetration performance of the cable by setting up a plastic protective layer manufacturing mechanism, thereby increasing the service life of the cable. By adding a metal wire mesh coiling mechanism, the cable is provided with wear-resistant performance, making the cable more stable in complex underground environments and extending its service life. However, the cross-section of the cable is a circular structure, and it is difficult to evenly compact the cable sheath layer using the existing pressing structure.

[0003] Due to structural design defects, existing cable sheath coating production equipment has problems such as the inability to fully mix and hot-melt the plastic particles, resulting in poor cable sheath molding quality, and the inability of the hot-melt plastic to evenly coat the outer surface of the core wire, which makes the cable easily trapped in water when entering the water tank for cooling.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] First embodiment: Figure 1-Figure 3 As shown, the present invention provides a technical solution: a cable sheath coating production device, comprising a base 1, a hot melt device 2 and a support table 7 are fixedly connected to the top of the base 1, one end of the hot melt device 2 is fixedly connected to an electric turntable 3, the output end of the electric turntable 3 is fixedly connected to a shear screw, and the side of the electric turntable 3 away from the hot melt device 2 is fixedly connected to a wire guide 4, and also includes:

[0039] Uniform hot extrusion mechanism 5, which is fixedly mounted on the side of the hot melt device 2 away from the electric turntable 3, and is used to roll and mix the hot melt sheared plastic and to coat the hot melt plastic fluid on the surface of the wire core;

[0040] The pressing mechanism 6 is fixedly mounted on the side of the uniform hot extrusion mechanism 5 away from the hot melting device 2, and is used for compacting the sheath covering the surface of the wire core;

[0041] A pulling mechanism 8 is fixedly mounted on the inner side of the support platform 7. A nozzle 9 is fixedly connected to the top of the support platform 7. The pulling mechanism 8 is used for limiting the position of the wire core sheath after coating and for pulling and rewinding the wire core sheath;

[0042] The uniform hot extrusion mechanism 5 includes a guide assembly 51 and a fixed plate 55. The guide assembly 51 is fixedly installed at the end surface of the shear screw. The surface of the guide assembly 51 is rotatably connected to a rolling assembly 54. The fixed plate 55 is fixedly installed at the end surface of the hot melt device 2. A primary cooling assembly 57 is fixedly connected to the side of the fixed plate 55 away from the hot melt device 2. The inner side surface of the fixed plate 55 is rotatably connected to the outer surface of the rolling assembly 54. The inner side surface of the rolling assembly 54 is fixedly connected to a barrier tube 56.

[0043] The uniform hot extrusion mechanism 5 further includes an annular guide rail 52 , which is fixedly mounted on the surface of the hot melting device 2 near the rolling assembly 54 , and a magnetic block 53 is fixedly connected to the output end of the annular guide rail 52 .

[0044] When in use, the conductor core passes through the wire guide 4 into the interior of the hot melt device 2, and the end of the barrier tube 56 away from the rolling component 54 extends to the electric turntable 3. The electric turntable 3 drives the shear screw to rotate, and the inner side of the shear screw is rotatably connected to the surface of the barrier tube 56. The plastic rubber particles are hot-melted under the shear force and flow to the guide component 51. At this time, some particles in the hot-melt fluid are not completely hot-melted. The guide component 51 guides the hot-melt fluid to the middle position. With the rotation of the guide component 51 and the shearing push of the shear screw, the hot-melt plastic fluid is squeezed to the position between the rolling component 54 and the guide component 51. The fluid is fully heated and pressurized in the rolling component 54 and the guide component 51 and hot-melted. The high-temperature fluid passes through the fixing plate 55 to the inner side of the primary cooling component 57. Under the guidance of the primary cooling component 57, the conductor core is coated with the hot-melt fluid and then passes through the pressing mechanism 6 and is wound on the surface of the pulling mechanism 8, which solves the problem that the plastic particles cannot be fully mixed and hot-melted, resulting in poor molding quality of the cable sheath.

[0045] Second embodiment: Figure 3 , Figure 4 , Figure 5 As shown, the guide assembly 51 includes a connecting block 511, a guide cylinder 513 is fixedly connected to the surface of the connecting block 511 near the edge, the end face of the guide cylinder 513 is fixedly installed at the end face of the shear screw, a feed gap 512 is opened in the middle position of the connecting block 511, and a material guide groove 514 is opened on the side of the connecting block 511 away from the guide cylinder 513. The rolling assembly 54 includes a perforated disk 541, the perforated disk 541 is rotatably connected to the side of the connecting block 511 near the material guide groove 514, and the rolling assembly 54 also includes a conical block 542, the conical block 542 is fixedly installed on the surface of the perforated disk 541 near the middle, and a spiral piece 543 is fixedly connected to the surface of the conical block 542 away from the perforated disk 541.

[0046] When in use, the inner side of the shearing screw is set to be hollow, and the guide cylinder 513 is fixedly installed at a position near the edge of the end face of the shearing screw. As the shearing screw rotates, the plastic and rubber particles are sheared and heated to a fluid state. At this time, there are still some unmelted particles inside the plastic fluid. The outer surface of the guide cylinder 513 is close to the inner side of the hot melting device 2. The plastic fluid flows to the inside of the feed gap 512 under the guidance of the guide cylinder 513 of the shrinking structure. The inner side of the hot melting device 2 slides and supports the perforated disk 541. The annular guide rail 5 2 drives the magnetic block 53 to rotate. A magnetic body is embedded in the perforated disk 541. The magnetic body and the magnetic block 53 are magnetically attracted to each other. The rotation of the magnetic block 53 causes the perforated disk 541 to rotate on the inner side of the hot melt device 2. The rotation direction is opposite to the rotation direction of the connecting block 511 and the shearing screw. With the shearing push of the shearing screw, the hot melt fluid passes through the perforated disk 541 through the guide groove 514 and flows to the fixed plate 55. The hot melt fluid is fully pressurized and mixed in the gap between the perforated disk 541 and the connecting block 511, so that the plastic fluid has better coating performance.

[0047] The third embodiment: Figure 3 , Figure 6 , Figure 7 As shown, the primary cooling component 57 includes a shell 571, one side of the shell 571 is fixedly mounted on the side of the fixing plate 55 away from the hot melting device 2, a through hole is opened on the surface of the fixing plate 55, a cavity 572 is arranged inside the shell 571, an air inlet cylinder 573 is fixedly connected to the side of the shell 571 away from the fixing plate 55, and an air inlet pipe 574 is fixedly connected to the surface of the air inlet cylinder 573;

[0048] The pressing mechanism 6 includes a rectangular frame 61, which is fixedly installed on the side of the air intake cylinder 573 away from the shell 571.

The pressing mechanism 6 also includes a first steel wire 63 and a second steel wire 64. The first steel wire 63 and the second steel wire 64 are both spiral structures. The end faces of the first steel wire 63 and the second steel wire 64 are fixedly installed at the output end of the hydraulic cylinder 62.

[0049] When in use, the conductor wire core passes through the barrier tube 56 and the conical block 542 to the inner side of the shell 571, and the heat transfer oil is poured into the cavity 572 to control the temperature of the shell 571 to prevent the hot melt fluid from cooling and solidifying and blocking when flowing through the inner side of the shell 571. A gap is set between the conical block 542 and the shell 571, and the plastic fluid flows to the surface of the conductor wire core in the gap. After the wire core is coated with the plastic fluid, it is led out through the air inlet cylinder 573, and the air inlet pipe 574 is transported to the inside of the air inlet cylinder 573. The cooling gas completes primary cooling of the sheath inside the air inlet cylinder 573, and then the sheath and the wire core are pulled into the interior of the rectangular frame 61. The cross-sectional diameter of the first steel wire 63 is relatively large, and the two ends of the first steel wire 63 are pulled by the hydraulic cylinder 62 to reduce the winding diameter, so that the surface of the first steel wire 63 is in close contact with the surface of the sheath and squeezes each other. After the primary cooling, the sheath and the wire core are subjected to an annular pushing force, which makes the sheath and the wire core more densely wrapped, and at the same time, the surface of the sheath is not damaged.

[0050] Fourth embodiment: Figure 3 , Figure 8 As shown, the guide assembly 51 is fixedly installed at the end surface of the shear screw, the surface of the guide assembly 51 is rotatably connected to the rolling assembly 54, the fixed plate 55 is fixedly installed at the end surface of the hot melt device 2, the side of the fixed plate 55 away from the hot melt device 2 is fixedly connected to the primary cooling assembly 57, the inner side surface of the fixed plate 55 is rotatably connected to the outer surface of the rolling assembly 54, and the inner side surface of the rolling assembly 54 is fixedly connected to the barrier tube 56;

[0051] The rectangular frame 61 is fixedly mounted on a side of the air inlet cylinder 573 away from the housing 571. A hydraulic cylinder 62 is fixedly connected to the surface of the rectangular frame 61. There are multiple hydraulic cylinders 62. The pressing mechanism 6 also includes a first steel wire 63 and a second steel wire 64. The first steel wire 63 and the second steel wire 64 are both spiral structures. The end surfaces of the first steel wire 63 and the second steel wire 64 are fixedly mounted on the output end of the hydraulic cylinder 62.

[0052] The pulling mechanism 8 includes a fixed platform 81, which is fixedly installed on the bottom of the inner side of the support platform 7. The top of the inner side of the fixed platform 81 is rotatably connected to a guide roller 82. The surface of the support platform 7 is fixedly connected to a motor 83. The pulling mechanism 8 also includes a limit platform 84, which is fixedly installed on the outer surface of the support platform 7. The surface of the limit platform 84 is rotatably connected to a rotating wheel 85. One end of the rotating wheel 85 extends to the inner side of the motor 83. The surface of the rotating wheel 85 is fixedly connected to a pressing assembly 86.

[0053] When in use, the pressing assembly 86 fixes and installs the end surface of the sheath and the wire core, and the motor 83 drives the rotating wheel 85 to rotate. After the sheath passes through the guide roller 82, it is guided downward by the guide roller 82 to the surface of the rotating wheel 85 for winding. The rotating wheel 85 is located directly below the guide roller 82. After the wire core passes through the wire guide 4, it is guided to the barrier tube 56. After passing through the barrier tube 56, the wire core is introduced into the primary cooling assembly 57 for plastic coating. After the coating is completed, the primary cooling assembly 57 performs primary plastic coating on the outer surface of the sheath. After the cooling treatment, the sheath is pulled by the rotating wheel 85 through the first steel wire 63. The surface of the first steel wire 63 is treated with plastic dipping to reduce the friction between the sheath and the second steel wire 64. The second steel wire 64 is inserted into the interior of the first steel wire 63. At the same time, both ends of the second steel wire 64 are also in a tensioned state, which makes the first steel wire 63 more stable when pressed and the structure between the sheath and the wire core is denser, which solves the problem that the hot-melt plastic cannot be evenly coated on the outer surface of the core wire and the cable is prone to water when entering the water tank for cooling.

[0054] Fifth embodiment: Figure 5 , Fig. 9 As shown, the perforated disk 541 is rotatably connected to a side of the connecting block 511 near the guide groove 514, and the rolling assembly 54 further includes a conical block 542, which is fixedly mounted on a surface of the perforated disk 541 near the middle, and a spiral piece 543 is fixedly connected to a surface of the conical block 542 away from the perforated disk 541;

When installed, the limit platform 84 is fixedly installed on the surface of the support platform 7, and the rotating wheel 85 is driven to the inner side of the fixed platform 81. The middle position of the rotating wheel 85 extends to the inner side of the motor 83, and the motor 83 and the rotating wheel 85 are quickly engaged. The rotating wheel 85 is inside the fixed platform 81, and the end face of the sheath passes through the guide roller 82 to the inside of the penetration hole 862, and the hoist 863 drives the pressing block 864 to close the inner side of the fixed platform 81. The sheath is close to the outer sleeve so that the end face of the sheath is clamped quickly and stably. The motor 83 drives the rotating wheel 85 to rotate. The cable sheath is wound on the surface of the connecting tube 861 and the rotating wheel 85. The wire core is transported through the conical block 542 along the middle position of the hot melt device 2. The conical block 542 rotates with the perforated disk 541. The rotating lift of the spiral sheet 543 causes the plastic fluid to be coated on the surface of the wire core under the extrusion effect. At the same time, under the pulling force, the axis of the wire core is always parallel to the ground, so that the plastic fluid is coated more evenly and densely.
