Description

Technical Field

[0001] This utility model relates to the technical field of cables and production equipment, specifically to a Class A special control cable with copper wire PVC insulation and sheath double shielding, anti-interference and flame retardant, and related production equipment. Background Technology

[0002] A cable is an electrical energy or signal transmission device consisting of one or more mutually insulated conductors and an outer protective covering. The inner conductor is typically made of highly conductive copper or aluminum, responsible for transmitting current or signals; the insulation layer uses materials such as polyvinyl chloride (PVC) or cross-linked polyethylene (XLPE) to prevent current leakage and signal interference; the outer protective layer includes a shielding layer, an armor layer, and an outer sheath. The shielding layer resists electromagnetic interference, the armor layer (such as galvanized steel tape) provides mechanical protection and enhances compressive and tensile strength, and the outer sheath, mostly made of PVC or polyethylene, serves to prevent moisture, corrosion, and abrasion. Due to its safety, stability, flexible installation, and high transmission efficiency, cables are widely used in power transmission, communication networks, industrial control, and building wiring, playing an indispensable role in modern society's energy supply and information transmission.

[0003] However, the anti-interference and flame-retardant capabilities of cables on the market can be further improved. At the same time, the cutting equipment in the cable production process is usually fixed, with poor mobility and insufficient flexibility. Therefore, we have proposed a special Class A control cable with copper wire PVC insulation and sheath double shielding, anti-interference and flame retardant, as well as its production equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a copper wire PVC insulated and sheathed double-shielded anti-interference and flame-retardant Class A special control cable and its production equipment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A Class A special control cable with copper wire PVC insulation and sheath, double shielding, interference resistance, and flame retardancy, comprising a PVC outer sheath layer, a galvanized steel tape armor layer fixedly disposed inside the PVC outer sheath layer, an inner lining layer fixedly disposed inside the galvanized steel tape armor layer, a copper wire braided layer fixedly disposed inside the inner lining layer, a first polyester tape layer fixedly disposed inside the copper wire braided layer, a copper-plastic composite tape layer fixedly disposed inside the first polyester tape layer, a second polyester tape layer fixedly disposed inside the copper-plastic composite tape layer, a filler layer fixedly disposed inside the second polyester tape layer, a PVC insulation layer fixedly disposed inside the filler layer, a mica tape layer fixedly disposed inside the PVC insulation layer, and a copper conductor fixedly disposed inside the mica tape layer.

[0006] The copper-plastic composite tape layer and copper wire braided layer further enhance the cable's anti-interference capability, ensuring stable operation. The zinc layer on the surface of the galvanized steel tape armor layer effectively resists acid and alkali corrosion, oxidation corrosion, and other corrosive factors, extending the cable's service life. The PVC outer sheath layer uses high-oxygen-index, high-shell-forming, and low-heat-release PVC sheath material, which has certain flame-retardant properties and is not easily ignited when exposed to open flames, effectively preventing the spread of fire and reducing the risk of fire.

[0007] Production equipment for copper wire PVC insulated and sheathed double-shielded anti-interference and flame-retardant Class A special control cables includes a mobile platform, the bottom of which is equipped with a fixed shaft, and the bottom of the fixed shaft is rotatably connected to a self-locking universal wheel.

[0008] As a further embodiment of this utility model: the fixed shafts are distributed at the four bottom corners of the moving platform, and a cutting table is fixedly installed on the top of the moving platform.

[0009] The above solution allows the cable to be placed on a cutting table by setting up a cutting table.

[0010] As a further improvement of this utility model: the cutting table has a cutting opening in the middle, and the cutting opening has a cutting groove in the middle.

[0011] The above solution allows the cutting blade to move within a cutting groove by setting a cutting groove.

[0012] As a further improvement of this utility model: an electric telescopic rod is fixedly installed inside the mobile platform, and a push rod is movably installed at one end of the electric telescopic rod.

[0013] The above solution uses an electric telescopic rod to control the lifting of the push rod, thereby enabling the lifting plate to rise and fall.

[0014] As a further improvement of this utility model: a lifting plate is fixedly provided at the top of the push rod, and a cutting blade is fixedly provided at the bottom of the lifting plate.

[0015] The above solution involves setting up a lifting plate, which in turn drives the cutting blade to move up and down.

[0016] As a further improvement of this utility model: the cutting blade is located at the top of the cutting groove, and the cutting blade and the cutting groove are matched.

[0017] The above method involves placing the cable on top of the cutting groove, and then cutting the cable using a cutting blade that works in conjunction with the cutting groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are: 1. This copper wire PVC insulated and sheathed double-shielded Class A special control cable, with anti-interference and flame-retardant properties, further enhances its anti-interference capability through the addition of a copper-plastic composite tape layer and a copper wire braided layer, ensuring stable operation. The zinc layer on the surface of the galvanized steel tape armor layer effectively resists acid and alkali corrosion, oxidation corrosion, and other corrosive factors, extending the cable's service life. The PVC outer sheath layer uses high-oxygen-index, high-shell-forming, and low-heat-release PVC sheath material, which has certain flame-retardant properties and is not easily ignited when exposed to open flames, effectively preventing the spread of fire and reducing the risk of fire. These design features improve the device's anti-interference and flame-retardant capabilities.

[0019] 2. The production equipment for this copper wire PVC insulated and sheathed double-shielded anti-interference and flame-retardant Class A special control cable has improved mobility through the setting of a moving platform, fixed shaft and self-locking casters. When cutting is required, the self-locking casters are locked, and then the cable is placed on the cutting opening at the top of the cutting platform. Then, through the combined action of the electric telescopic rod and the push rod, the lifting plate drives the cutting blade to cut the cable. Attached Figure Description

[0023] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution: A Class A special control cable with copper wire PVC insulation and sheath double shielding, interference resistance, and flame retardancy, comprising a PVC outer sheath layer 1, a galvanized steel tape armor layer 2 fixedly installed inside the PVC outer sheath layer 1, an inner lining layer 3 fixedly installed inside the galvanized steel tape armor layer 2, a copper wire braided layer 4 fixedly installed inside the inner lining layer 3, a first polyester tape layer 5 fixedly installed inside the copper wire braided layer 4, a copper-plastic composite tape layer 6 fixedly installed inside the first polyester tape layer 5, a second polyester tape layer 7 fixedly installed inside the copper-plastic composite tape layer 6, a filler layer 8 fixedly installed inside the second polyester tape layer 7, a PVC insulation layer 9 fixedly installed inside the filler layer 8, a mica tape layer 10 fixedly installed inside the PVC insulation layer 9, and a copper conductor 11 fixedly installed inside the mica tape layer 10.

[0024] The copper-plastic composite tape layer 6 and copper wire braided layer 4 further enhance the cable's anti-interference capability, ensuring stable operation. The zinc layer on the surface of the galvanized steel tape armor layer 2 effectively resists acid and alkali corrosion, oxidation corrosion, and other corrosive factors, extending the cable's service life. The PVC outer sheath layer 1 uses high-oxygen-index, high-shell-forming, and low-heat-release PVC sheath material, which has certain flame-retardant properties and is not easily ignited when exposed to open flames, effectively preventing the spread of fire and reducing the risk of fire.

[0025] Production equipment for copper wire PVC insulated and sheathed double-shielded anti-interference and flame-retardant Class A special control cables includes a movable platform 12, a fixed shaft 13 at the bottom of the movable platform 12, and a self-locking universal wheel 14 rotatably connected to the bottom of the fixed shaft 13.

[0026] As a further improvement of this utility model: fixed shafts 13 are distributed at the four bottom corners of the moving platform 12, a cutting table 15 is fixedly installed on the top of the moving platform 12, a cutting opening 16 is opened in the middle of the cutting table 15, a cutting groove 17 is opened in the middle of the cutting opening 16, an electric telescopic rod 18 is fixedly installed inside the moving platform 12, a push rod 19 is movably installed at one end of the electric telescopic rod 18, a lifting plate 20 is fixedly installed on the top of the push rod 19, a cutting blade 21 is fixedly installed at the bottom of the lifting plate 20, the cutting blade 21 is located on the top of the cutting groove 17, and the cutting blade 21 and the cutting groove 17 are matched.

[0027] The above scheme allows the cable to be placed on the cutting table 15, the cutting blade 21 to move inside the cutting groove 17, and the lifting plate 20 to be raised and lowered by the electric telescopic rod 18 controlling the lifting of the push rod 19. The lifting plate 20 drives the cutting blade 21 to rise and fall. The cable is placed on the top of the cutting groove 17, and then the cutting blade 21 and the cutting groove 17 work together to cut the cable.

[0028] In this embodiment, the copper wire PVC insulated and sheathed double-shielded anti-interference and flame-retardant Class A special control cable and production equipment, through the copper-plastic composite tape layer 6 and copper wire braided layer 4, further enhance the cable's anti-interference capability, ensuring stable operation. The zinc layer on the surface of the galvanized steel tape armor layer 2 effectively resists acid and alkali corrosion, oxidation corrosion, and other corrosive factors, extending the cable's service life. The PVC outer sheath layer 1 uses high oxygen index, high shell formation, and low heat release PVC sheath material, which has certain flame-retardant properties and is not easily ignited when exposed to open flame, effectively preventing the spread of fire and reducing the risk of fire. The above design improves the device's anti-interference and flame-retardant capabilities. The movable platform 12, fixed shaft 13, and self-locking universal wheels 14 further enhance the device's mobility. When cutting is required, the self-locking universal wheels 14 are locked, and the cable is placed on the cutting opening 16 at the top of the cutting platform 15. Then, through the combined action of the electric telescopic rod 18 and the push rod 19, the lifting plate 20 drives the cutting blade 21 to cut the cable.
