Description

Technical Field

[0001] This invention relates to the field of warehouse racking technology, and in particular to an FEP spiral wound tube. Background Technology

[0002] Traditional spiral wound tubes are prone to breakage during prolonged use due to their low strength, rendering them unable to effectively protect wires and cables.

[0003] Existing FEP spiral wound tubes include a main body, with reinforcing members wound and fixedly connected to its outer surface. A functional layer is located on the inner side of the main body's outer surface, containing a flame-retardant layer of FEP and an anti-aging layer of ASA material. A toughness layer is fixedly connected to the inner side of the functional layer, a heat insulation layer is fixedly connected to the inner side of the toughness layer, and a shielding layer is fixedly connected to the inner side of the heat insulation layer. By adding reinforcing strips to the surface of the main body, the overall toughness of the spiral wound tube can be improved. The addition of a carbon fiber reinforcing layer makes the tube even stronger and less prone to breakage. Furthermore, by penetrating and fixing a diagonally interwoven steel wire mesh inside the reinforcing layer, the overall strength of the spiral wound tube is enhanced, preventing breakage during long-term use and effectively extending its service life.

[0004] However, existing spiral wound tubes are easily subjected to external pressure or impact during use, which can transmit the impact force to the cable through the tube, thus easily damaging the cable. Summary of the Invention

[0005] The purpose of this invention is to provide an FEP spiral wound tube, which aims to solve the problem that existing spiral wound tubes are easily subjected to external compression or impact during use, causing the impact force to be transmitted to the cable through the tube and thus easily damaging the cable.

[0006] To achieve the above objectives, the present invention provides an FEP wound tube, comprising a wound tube body, characterized in that,

[0007] It also includes buffer components,

[0008] The buffer assembly includes an arched rubber frame and a buffer cylinder. The arched rubber frame is connected to the main body of the winding tube and is located on one side of the main body of the winding tube. The buffer cylinder is connected to both the arched rubber frame and the main body of the winding tube, and is located between the arched rubber frame and the main body of the winding tube.

[0009] The FEP winding tube further includes an insulating layer, which is connected to the arched rubber frame and located on one side of the arched rubber frame.

[0010] The FEP winding tube further includes a shielding layer, which is connected to the insulating layer and located on the side of the insulating layer away from the arched rubber frame.

[0011] The FEP wound tube further includes a heat insulation layer, which is connected to the shielding layer and located on the side of the shielding layer away from the insulating layer.

[0012] The FEP spiral wound tube further includes a functional layer, which includes a flame-retardant layer and an anti-aging layer. The flame-retardant layer is connected to the heat insulation layer and is located on the side of the heat insulation layer away from the shielding layer. The anti-aging layer is connected to the flame-retardant layer and is located on the side of the flame-retardant layer away from the heat insulation layer.

[0013] The functional layer further includes a halogen-free flame retardant, and the flame retardant layer contains the halogen-free flame retardant.

[0014] The FEP wound tube further includes a toughness layer, which comprises a carbon fiber reinforcement layer and a steel wire mesh. The carbon fiber reinforcement layer is connected to the anti-aging layer and is located on one side of the anti-aging layer. The steel wire mesh is disposed in the carbon fiber reinforcement layer.

[0015] The toughness layer further includes a thermally conductive filler, which is added to the carbon fiber reinforcing layer.

[0016] The toughness layer further includes a weather-resistant layer, which is connected to the carbon fiber reinforcement layer and located on one side of the carbon fiber reinforcement layer.

[0017] The present invention discloses an FEP spiral wound tube. When the main body of the spiral wound tube is subjected to pressure or impact, the impact force is transmitted to the arched rubber frame, causing the arched rubber frame to compress and deform, thus buffering the impact force. At the same time, during the compression and deformation of the arched rubber frame, the buffer cylinder between the arched rubber frame and the main body of the spiral wound tube is also squeezed. Through the stability of the arched structure of the arched rubber frame and the deformation buffer of the buffer cylinder, the cable in the main body of the spiral wound tube is protected against impact, preventing the cable from being damaged by the impact force.

Detailed Implementation

[0025] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] The first embodiment of this application is:

[0027] Please see Figure 1 ,in Figure 1 This is a schematic diagram of the structure of the FEP winding tube according to the first embodiment of the present invention.

[0028] This invention provides an FEP spiral wound tube, comprising a wound tube body 101, a buffer assembly 102, an insulation layer 103, a shielding layer 104, and a heat insulation layer 105. The buffer assembly 102 includes an arched rubber frame 106 and a buffer cylinder 107. This solution addresses the problem that existing spiral wound tubes are easily subjected to external pressure or impact during use, causing the impact force to be transmitted through the tube to the cable, thus easily damaging the cable. It is understood that the aforementioned solution can be used to give the spiral wound tube impact resistance.

[0029] In this embodiment, the main body 101 of the spiral tube is an FEP spiral tube, which can wrap and protect the cable.

[0030] The arched rubber frame 106 is connected to the winding tube body 101 and located on one side of the winding tube body 101. The buffer cylinder 107 is connected to both the arched rubber frame 106 and the winding tube body 101, and is located between the arched rubber frame 106 and the winding tube body. Multiple arched rubber frames 106 are connected and fixed to the winding tube body 101. The arched rubber frames 106 are evenly distributed in a circular shape on the winding tube body 101. The buffer cylinders 107 are also evenly distributed in a circular shape on the winding tube body 101 and are correspondingly connected between the corresponding multiple arched rubber frames 106 and the winding tube body 101. All columns 107 are made of rubber, possessing a certain deformation recovery capability. Power cables can be placed and installed within the main body 101 of the winding tube, thus protecting the cables. When the main body 101 of the winding tube is subjected to pressure or impact, the impact force is transmitted to the arched rubber frame 106, causing the arched rubber frame 106 to compress and deform, buffering the impact force. Simultaneously, during the compression and deformation of the arched rubber frame 106, the buffer cylinder 107 between the arched rubber frame 106 and the main body of the winding tube is also compressed. Through the stability of the arched structure of the arched rubber frame 106 and the deformation buffering of the buffer cylinder 107, the cables within the main body 101 are protected against impact, preventing damage to the cables.

[0031] Secondly, the insulating layer 103 is connected to the arched rubber frame 106 and is located on one side of the arched rubber frame 106. The insulating layer 103 is connected to multiple arched rubber frames 106. The insulating layer 103 is made of polyethylene. By using the polyethylene insulating layer 103, the wires and cables wound inside the winding tube can be insulated and protected, thereby improving the safety of the device.

[0032] Meanwhile, the shielding layer 104 is connected to the insulating layer 103 and is located on the side of the insulating layer 103 away from the arched rubber frame 106. The shielding layer 104 is connected to the insulating layer 103. The shielding layer 104 is composed of soft aluminum foil and polyester film. By using soft aluminum foil and polyester film as raw materials and composite aluminum foil Mylar material with gravure coating, the shielding layer 104 can effectively avoid electromagnetic interference from external electromagnetic fields to the wires and cables wound inside the winding tube, and ensure the normal information transmission of the wires and cables.

[0033] Finally, the heat insulation layer 105 is connected to the shielding layer 104 and is located on the side of the shielding layer 104 away from the insulating layer 103. The heat insulation layer 105 is connected to the shielding layer. The heat insulation layer 105 is heat insulation cotton, which can effectively prevent damage to the wires and cables wound inside the winding tube due to external high temperature.

[0034] When using the FEP spiral wound tube of this embodiment, when the spiral wound tube body 101 is subjected to pressure or impact, the impact force is transmitted to the arched rubber frame 106, causing the arched rubber frame 106 to compress and deform to buffer the impact force. At the same time, during the compression and deformation of the arched rubber frame 106, the buffer cylinder 107 between the arched rubber frame 106 and the spiral wound tube body is also squeezed. Through the stability of the arched structure of the arched rubber frame 106 and the deformation buffer of the buffer cylinder 107, the cable in the spiral wound tube body 101 is protected against impact, preventing the cable from being damaged by impact force.

[0035] The second embodiment of this application is as follows:

[0036] Based on the first embodiment, please refer to Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure of the FEP winding tube according to the second embodiment of the present invention. Figure 3 This is a schematic diagram of the functional layer structure of the second embodiment of the present invention.

[0037] The present invention provides an FEP spiral tube that further includes a functional layer 201, wherein the functional layer 201 includes a flame retardant layer 202, an anti-aging layer 203, and a halogen-free flame retardant 204.

[0038] The flame-retardant layer 202 is connected to the heat insulation layer 105 and is located on the side of the heat insulation layer 105 away from the shielding layer 104. The anti-aging layer 203 is connected to the flame-retardant layer 202 and is located on the side of the flame-retardant layer 202 away from the heat insulation layer 105. The flame-retardant layer 202 is connected to the heat insulation layer 105. The flame-retardant layer 202 is made of FEP material, which can prevent the flame from spreading in the event of a fire. The anti-aging layer 203 is made of ASA material, which gives the entire spiral wound tube an anti-aging effect and can extend its service life. The flame-retardant layer 202 contains the halogen-free flame retardant 204. The halogen-free flame retardant 204 is directly mixed into the flame-retardant layer 202. The halogen-free flame retardant 204 is mixed directly with FEP resin in powder or masterbatch form, and the flame-retardant layer 202 is formed by extrusion or injection molding. It can ensure that the flame retardant is evenly dispersed inside the material, forming a stable flame retardant system, avoiding the decline in flame retardant performance due to surface wear, and at the same time reducing the toxic gases and smoke produced during combustion, thus improving the safety and environmental friendliness of the product.

[0039] The flame-retardant layer 202, anti-aging layer 203, and halogen-free flame retardant 204 prevent the spread of flames in the event of a fire. The anti-aging layer 203 provides overall anti-aging protection for the spiral wound tube, extending its service life. The halogen-free flame retardant 204 ensures uniform dispersion of the flame retardant within the material, forming a stable flame-retardant system and preventing a decline in flame-retardant performance due to surface wear. It also reduces toxic gases and fumes produced during combustion, improving product safety and environmental friendliness.

[0040] The third embodiment of this application is as follows:

[0041] Based on the second embodiment, please refer to Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of the FEP winding tube according to the third embodiment of the present invention. Figure 5 This is a schematic diagram of the toughness layer in the third embodiment of the present invention.

[0042] The present invention provides an FEP spiral tube that further includes a toughness layer 301, wherein the toughness layer 301 includes a carbon fiber reinforcement layer 302, a steel wire mesh 303, a thermally conductive filler 304, and a weather-resistant layer 305.

[0043] The carbon fiber reinforcing layer 302 is connected to the anti-aging layer 203 and located on one side of the anti-aging layer 203. The steel wire mesh 303 is disposed in the carbon fiber reinforcing layer 302 and connected to the anti-aging layer 203. The carbon fiber reinforcing layer 302 is made of carbon fiber, which makes the winding tube more durable and less prone to breakage. Furthermore, the inclined interwoven steel wire mesh 303, which penetrates and is fixedly installed inside the carbon fiber reinforcing layer 302, further enhances the overall strength of the winding tube, preventing breakage during long-term use and effectively extending its service life. The carbon fiber reinforcing layer 302 contains a thermally conductive filler 304, which is made of graphene. This filler improves the thermal conductivity of the winding tube, aiding in heat dissipation and preventing performance degradation due to overheating, thus improving the reliability and safety of the winding tube.

[0044] The weather-resistant layer 305 is connected to the carbon fiber reinforcing layer 302 and is located on one side of the carbon fiber reinforcing layer 302. The weather-resistant layer 305 is made of polycarbonate material with added UV stabilizer. The weather-resistant layer 305 can better improve the service life of the wound tube and better protect the internal structure of the tube.

[0045] By inserting and fixing the inclined interwoven steel wire mesh 303 inside the carbon fiber reinforcing layer 302, the overall strength of the spiral wound tube is improved, making it less prone to breakage during long-term use and effectively extending its service life. At the same time, the thermally conductive filler 304 can improve the thermal conductivity of the spiral wound tube, which helps to dissipate heat and prevents the performance of the spiral wound tube from deteriorating due to overheating, thereby improving the reliability and safety of the spiral wound tube.
