BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 It is a schematic diagram of the cross-sectional structure of a high-tensile-resistance flexible combined cable for a digital intelligent manufacturing workshop provided according to an embodiment of the present invention. DETAILED DESCRIPTION

[0024] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0025] Various aspects of the utility model are described in the present disclosure with reference to the accompanying drawings, in which many illustrative embodiments are shown. The embodiments of the present disclosure are not necessarily intended to include all aspects of the utility model. It should be understood that the various concepts and embodiments introduced above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed by the utility model are not limited to any implementation. In addition, some aspects disclosed by the utility model can be used alone, or in any appropriate combination with other aspects disclosed by the utility model.

[0026] Combination Figure 1 The high-tensile-resistance flexible combined cable for a digital intelligent manufacturing workshop of the example shown includes a power core 10 , a monitoring core 20 , a filling rope 30 , a first isolation tape layer 40 , a flexible composite braided tape layer 50 and an outer sheath layer 60 .

[0027] Combination Figure 1 As shown, between a group of power cores 10 designed in pairs and a group of monitoring cores 20 designed in pairs, a circular cross-section cable core is formed by the power cores 10 and the monitoring cores 20 being spaced apart, and filling ropes 30 are filled in the center position of the cable core and the circumscribed interval positions between any two power cores 10 and the monitoring cores 20.

[0028] As an optional example, taking two power cores 10 and two monitoring cores 20 as an example, each power core 10 is tangent to each monitoring core 20 in sequence and arranged at intervals; the two power cores 10 and the two monitoring cores 20 form a cross-orthogonal distribution in the interface direction of the cable core, and glass fiber ropes are filled as filling ropes 30 at the circumscribed interval positions of any adjacent power cores 10 and monitoring cores 20, and glass fiber ropes embedded with fine steel wires are filled as filling ropes 30 at the center position of the cable core.

[0029] Therefore, the glass fiber rope filled on the outside of the power core 10 and the monitoring core 20 ensures the roundness and flame retardant performance of the cable, effectively maintains the circular structure of the cable, prevents its shape from changing, ensures the cable core's resistance to external impact and extrusion, and the glass fiber rope with embedded fine steel wires filled in the center ensures roundness and tensile and torsional properties, resists the risk of cable damage caused by the reciprocating rotation and torsion of equipment in the digital intelligent manufacturing workshop, and enhances the strength and toughness of the glass fiber rope through the implantation of fine steel wires, so that the cable can maintain stability when stretched or torsioned, and is not prone to deformation or breakage, thereby ensuring the integrity and stability of the cable core.

[0030] like Figure 1 As shown, the halogen-free flame retardant tape wrapped around the outside of the cable core constitutes a first isolation tape layer 40 .

[0031] The flexible composite braided tape layer 50 is braided and formed by aramid wires and stainless steel wires in a preset manner, and is wrapped around the outside of the first isolation tape layer 40 to achieve external global shielding performance and ensure the tensile and torsional resistance of the combined cable.

[0032] like Figure 1 The outer sheath layer 60 is made of polyvinyl chloride sheath, which is extruded on the outside of the flexible composite braided belt layer 50 to form an overall external protection, which plays the role of electrical insulation, fatigue resistance, mechanical damage resistance, wear resistance, corrosion resistance, temperature resistance and flame retardancy, ensuring the normal operation of the cable and extending its service life.

[0033] As an optional embodiment, the power core 10 includes a power core conductor 11 composed of a Category VI tinned annealed conductor, and a halogen-free EPDM rubber insulation layer 12 extruded on the outside of the power core conductor 11 as a conductor insulation layer.

[0034] As an optional embodiment, the monitoring core 20 includes a monitoring core conductor 21, a monitoring core insulation 22, an aluminum-plastic composite tape 23, a tinned braided shielding layer 24, a second isolation tape layer 25, and an inner sheath 26, which are arranged sequentially from the inside to the outside along the cross-sectional direction. The inner sheath 26 can be made of a flame-retardant nitrile sheath to provide electrical insulation, flame retardancy, and temperature resistance protection for the monitoring core.

[0035] As an optional embodiment, the aluminum-plastic composite tape 23 adopts a single-sided metal composite tape composed of a single-sided aluminum metal film and a plastic reinforcement layer. The single-sided aluminum metal film faces the monitoring wire core insulation 22 side and is wrapped in a longitudinal wrapping manner, with 2 layers wrapped and an overlap rate of 35% to 55%; the plastic reinforcement layer adopts at least one of polyethylene, polypropylene, polyester, polyimide, and polytetrafluoroethylene propylene, and the thickness of the single-sided aluminum metal film is 0.05mm to 0.08mm.

[0036] Therefore, the aluminum-plastic composite tape 23 is a single-sided metal composite tape composed of a single-sided aluminum metal film and a plastic reinforcement layer, which can provide mechanical protection and good electromagnetic shielding. The single-sided aluminum metal film faces the monitoring wire core insulation 22 and is wrapped in a longitudinal wrapping manner to form a protective layer for the wire core insulation. The aluminum metal film achieves electromagnetic shielding, blocks the propagation of electromagnetic waves, reduces the impact of electromagnetic interference (EMI), and ensures the stability and reliability of signal transmission. The overlap rate is controlled at 35% to 55%, which can ensure the close fit and coverage between the aluminum metal films and ensure the shielding effect.

[0037] As an optional embodiment, the tinned braided shielding layer 24 is formed by braiding tinned copper wires at a braiding angle of 45° and is wrapped around the outside of the plastic reinforcement layer of the aluminum-plastic composite tape 23 .

[0038] Thus, the tinned braided shielding layer is made of tinned copper wire, woven at a braiding angle of 45°, with a braiding density of 85%, forming a tight mesh structure, effectively blocking the propagation of electromagnetic waves, playing the role of electromagnetic shielding, reducing the impact of electromagnetic interference (EMI), and ensuring the stability and reliability of signal transmission. At the same time, the tinned braided shielding layer also has a mechanical protection effect on the aluminum-plastic composite tape 23, wrapped around the outside of the plastic reinforcement layer of the aluminum-plastic composite tape 23, providing additional protection for the internal reinforcement layer, preventing it from being damaged by external mechanical damage, and enhancing the durability and stability of the cable.

[0039] As an optional embodiment, the second isolation tape layer 25 is formed by wrapping flame retardant yarn, with two layers wrapped and an overlap rate of 35% to 45%. The flame retardant yarn has good flame retardant properties and can effectively prevent the spread of flames when a fire occurs, reducing the degree of damage to the cable caused by the fire.

[0040] As an optional embodiment, the aramid wires and stainless steel wires in the flexible composite braided tape layer 50 are formed by interlaced weaving and woven around the outside of the first isolation tape layer 40, providing better mechanical strength, toughness and protective performance for the cable core.

[0041] In the embodiment of the utility model, the aramid yarn used has good tensile strength and elastic modulus, which can improve the rigidity and durability of the composite braided belt, so that the braided belt is not easy to deform or break under torsion or external tension. Combined with the tensile strength and hardness of the stainless steel wire, the protective performance and wear resistance of the composite braided belt can be enhanced. At the same time, the aramid yarn and the stainless steel wire have excellent wear resistance and chemical corrosion resistance, which can maintain the stable performance of the braided belt.

[0042] By adopting the interlaced weaving forming method, the aramid wire and the stainless steel wire can be closely combined together to form a composite weaving structure.
