Description

Technical Field

[0001] This invention relates to the field of vulcanized fabrics, and in particular to vulcanized fabrics, vulcanized fabric processing apparatus, and vulcanized fabric processing methods. Background Technology

[0002] Adding sulfur, carbon black, and other substances to raw rubber and heating it under high pressure transforms it into vulcanized rubber—a process called vulcanization. Cloths, for example, have their tensile strength increased by vulcanizing rubber onto their surface. The vulcanization process typically involves covering the fabric surface with rubber and then subjecting it to high-temperature, high-pressure vulcanization using a rolling vulcanization device. However, with the development of vulcanized fabric's functionalities, its existing structure can no longer meet the demands of use. For instance, when used for material loading, vulcanized fabric needs to adhere to the bottom of the material bags and be attached to the bottom of the vehicle compartment. Similarly, when used in tents, vulcanized fabric can detect temperature and light, automatically provide internal lighting, and offer temperature parameters for uncooled facilities. The existing structure of vulcanized fabric is far from capable of achieving these functions.

[0003] A utility model patent, CN 211492469 U, published on September 15, 2020, discloses a vulcanized fabric processing device. This device uses high-temperature metal particles at the top and a heat-conducting support platform at the bottom to dynamically vulcanize the rubber-impregnated fabric from both top and bottom directions. However, this patent has two problems: first, the metal particles cannot be replenished in a timely manner, requiring machine shutdown for each replenishment; second, to increase the strength of the vulcanized fabric, the vulcanization process needs to evenly impregnate the fabric with rubber, an effect that existing equipment struggles to achieve. Furthermore, multifunctional vulcanized fabrics have complex structures, and existing vulcanized fabric processing devices are unable to process such complex structures. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of this invention is to provide a vulcanized fabric that can effectively solve the problem of dynamic vulcanization of the fabric.

[0005] The technical solution solved by this invention is:

[0006] A vulcanized fabric includes an upper rubber layer, an intermediate fiber impregnation layer, and a lower rubber layer. The fiber impregnation layer comprises a fiber layer made of a blend of fibers and conductive metal wires and an impregnation layer therein. Each conductive metal wire contains at least four enameled wires. Every at least two conductive metal wires form a group. The spacing between adjacent conductive metal wires within each group is 0.5-2 cm, and the spacing between conductive metal wires in each group is 15-20 cm.

[0007] Preferably, the fiber is aramid 1414 fiber.

[0008] Preferably, the fiber layer is provided with electronic components, the electronic components are connected to corresponding conductive metal wires and encapsulated with potting compound, and plugs are provided on the metal wires connected to the electronic components.

[0011] Preferably, the functional element includes a lighting element and / or a processor.

[0012] Preferably, the impregnation in the fiber layer contains magnetic material particles.

[0013] A vulcanized fabric processing apparatus includes a glue-dipping unit, a storage unit, and a vulcanizing unit located between the glue-dipping unit and the storage unit. The glue-dipping unit includes a first glue impregnation tank and a second glue impregnation tank. The vulcanizing unit includes an upper heat-conducting film circulating conveyor roller group and a lower heat-conducting film circulating conveyor roller group. The upper heat-conducting film circulating conveyor roller group is positioned above the glued fabric and includes an upper pressure roller, an upper separation roller, an upper heat-conducting film deflector roller, and an upper heat-conducting film wound around the upper pressure roller, upper separation roller, and upper heat-conducting film deflector roller. The upper heat-conducting film between the upper pressure roller and the upper separation roller is tightly adhered to the upper surface of the fabric. The lower heat-conducting film circulating... The conveyor roller assembly includes a lower pressure roller, a lower separation roller, a lower heat-conducting film guide roller, and a lower heat-conducting film wound around the lower pressure roller, the lower separation roller, and the lower heat-conducting film guide roller. The lower heat-conducting film between the lower pressure roller and the lower separation roller is tightly attached to the lower surface of the fabric. An annular conveyor belt is set below the lower heat-conducting film and is tightly attached to the lower heat-conducting film. The annular conveyor belt includes a conveyor belt body, a first conveyor wheel, and a second conveyor wheel. A support platform with a heating function is set at the bottom of the upper conveying surface of the conveyor belt body to support the upper conveying surface. A strip electromagnet is set below the support platform. A hopper with the discharge port facing downward is set above the front end of the annular conveyor belt to hold steel powder.

[0014] Preferably, a demagnetizing unit is provided behind the bar electromagnet.

[0015] Preferably, it further includes a steel powder collecting and heating mechanism, which includes a magnetic collecting unit, a transfer unit, and a heating unit; the magnetic collecting unit is located above the strip electromagnet and the demagnetizing unit, and includes a rotating shaft, a plurality of L-shaped first metal rods arranged along the axis of the rotating shaft, a positive conductive cylinder frictionally connected to the brushes of the first metal rods, a block electromagnet connected to the end of the first metal rods, a second metal rod connected to the block electromagnet, and a negative conductive cylinder frictionally connected to the brushes of the free end of the second metal rod, the negative conductive cylinder having a power-off gap. The first and second metal rods each include an electrical connection portion parallel to the axis of rotation and a right-angle bend portion connected to the block electromagnet. The bend portions of the first and second metal rods form a support rod for the block electromagnet. The transfer unit includes an L-shaped collection trough and a first conveyor belt disposed in the collection trough. The heating unit includes a heating trough and a second conveyor belt disposed in the heating trough. The lower end of the first conveyor belt is located at the bottom of the collection trough and the upper end is located above the rear end of the heating trough. The lower end of the second conveyor belt is located at the bottom of the rear end of the heating trough and the upper end of the second conveyor belt is located above the hopper.

[0016] The vulcanized fabric processing method according to the above-mentioned vulcanized fabric processing device includes the following steps:

[0017] Step 1: Blend fibers and conductive metal wires to form a fiber layer;

[0018] Step 2: Impregnate the fiber layer in the first and second adhesive impregnation tanks respectively to form an upper rubber layer, a middle fiber impregnation layer and a lower rubber layer.

[0019] Step 3: The resin-impregnated fiber layer is fed into the vulcanization unit for vulcanization. At the same time, the bar electromagnet is turned on to tightly adsorb the heated steel powder flowing out of the hopper onto the upper heat-conducting film, thereby tightly pressing the resin-impregnated fiber layer and vulcanizing the fiber layer.

[0020] Step 4: Steel powder is collected by magnetic collection unit and sent to transfer unit. It is then sent to heating unit for heating and returned to hopper. The vulcanized material is distributed in collection unit after vulcanization.

[0021] The vulcanized fabric of the present invention comprises a fiber impregnation layer consisting of a fiber layer made of a blend of fibers and conductive metal wires and an impregnation layer in the fiber layer. The placement of the conductive metal wires creates a conductive path in the vulcanized fabric, providing a basis for the placement of electronic components and laying the foundation for the flexible application of the vulcanized fabric. The impregnation of the enameled wires prevents leakage or signal loss.

[0022] Furthermore, electronic components are arranged in the fiber layer, and the electronic components are connected to corresponding conductive metal wires and encapsulated with potting compound. A plug is provided on the metal wire connected to the electronic components for connecting to power supply and external devices. The potting compound is used to prevent the electronic components from being interfered with.

[0023] Furthermore, the impregnation in the fiber layer contains magnetic material particles, which, after being magnetized, form a magnetic vulcanized fabric.

[0024] In this invention, the vulcanized fabric processing apparatus involves dipping the fiber layer in adhesive. During vulcanization in the vulcanization unit, a strip electromagnet is energized as needed. Steel powder at a temperature of 150-200°C flowing from the hopper is attracted by the electromagnet, increasing the pressure on the lower heat-conducting film. This presses the rubber firmly onto the fiber layer, accelerating its wetting and evenly embedding it into the fabric. Simultaneously, vulcanization occurs gradually, increasing the strength of the vulcanized fabric. Existing vulcanization apparatuses use an upper and lower roller extrusion method during vulcanization, which can easily damage some electronic components. In contrast, this vulcanized fabric processing apparatus uses a non-upper and lower roller hard extrusion method, which is more friendly to electronic components and can process vulcanized fabrics with complex structures.

[0025] Furthermore, when it is necessary to produce magnetic vulcanized cloth, neodymium iron boron microparticles are added to the second adhesive impregnation tank. After the fiber layer is impregnated in the second adhesive impregnation tank, it is vulcanized in the vulcanization unit. Due to the action of the strip electromagnet during the vulcanization process, the vulcanized cloth will have a certain degree of magnetism as a whole. A demagnetization unit is set behind the strip electromagnet to demagnetize the vulcanized cloth so that it can be magnetized in subsequent processes according to the magnitude of the magnetism and the needs of the magnetized parts. At the same time, it prevents the vulcanized cloth, which has greatly enhanced magnetic force due to its magnetism, from being attracted to the magnetic collection unit.

[0026] Furthermore, the steel powder collection and heating mechanism allows the steel powder passing through the strip electromagnet to be collected by the magnetic collection unit. When the block electromagnet is above the transfer unit, the corresponding block electromagnet is de-energized, and the steel powder falls into the transfer unit. It is then sent to the heating unit for heating via the first conveyor belt and returned to the hopper via the second conveyor belt, forming a cycle. This improves the utilization rate of steel powder and greatly saves the amount of steel powder used.

[0027] The vulcanized fabric processing method utilizes a vulcanized fabric processing device to conveniently and efficiently process the required complex structure of vulcanized fabric. Attached Figure Description

[0034] An example of a vulcanized fabric, such as Figures 1-3 As shown, the structure includes an upper rubber layer 1, a middle fiber impregnation layer 2, and a lower rubber layer 3. The fiber impregnation layer includes a fiber layer 4 composed of a blend of fiber and conductive metal wire 5, and impregnation within the fiber layer. Each conductive metal wire contains at least four enameled wires. At least two of the conductive metal wires form a group, with adjacent conductive metal wires within each group spaced 0.5-2 cm apart, and the spacing between conductive metal wires in each group is 15-20 cm. In this embodiment, the conductive metal wire contains four enameled wires, all of which are of the same diameter (0.07 mm). Adjacent conductive metal wires within each group are spaced 1 cm apart, and the spacing between conductive metal wires in each group is 15 cm. In this embodiment, the fiber is aramid 1414 fiber. The conductive metal wire can be blended with the fiber only as needed (e.g.,...). Figure 2 As shown), it can be used only as a warp and fiber blend or as both warp and weft blend with the fiber (e.g. Figure 3 As shown, a fiber layer is formed, and electronic components are disposed on the fiber layer. The electronic components are connected to corresponding conductive metal wires and encapsulated with glue. A plug 9 is disposed on the metal wire connected to the electronic components for connecting to a power source and external devices. In this embodiment, the vulcanized fabric can be used in a tent. The electronic components include both detection elements, such as a processor 7 and a light sensor 8, and functional electronic components, such as a lighting element 6.

[0035] In this embodiment, the vulcanized fabric has a fiber impregnation layer comprising a fiber layer made of a blend of fibers and conductive metal wires, and an impregnation layer within the fiber layer. The conductive metal wires create conductive paths within the vulcanized fabric, providing a basis for the placement of electronic components and enabling flexible applications of the vulcanized fabric. The impregnation of the enameled wires prevents leakage or signal loss. Electronic components are mounted on the fiber layer, connected to corresponding conductive metal wires, and encapsulated with adhesive. Plugs are mounted on the metal wires connected to the electronic components, and the encapsulation prevents interference with the electronic components.

[0036] Unlike Embodiment 1, the electronic component can also be a detection element or a functional electronic component. The detection element can be a temperature sensor and / or a pressure sensor, or it can be configured as other monitoring elements and functional electronic components as needed.

[0037] Vulcanized fabric is also used in material bags, especially at the bottom of the material bags. The fiber layer contains magnetic material particles in the impregnation, which are magnetized at the desired locations as needed, forming a magnetic vulcanized fabric after magnetization.

[0038] Vulcanized fabric processing equipment, such as Figures 4-6 As shown, it includes a glue-dipping unit, a storage unit, and a vulcanization unit located between the glue-dipping unit and the storage unit. The glue-dipping unit includes a raw fabric storage roller 10, a first intermediate roller 14, a second intermediate roller 17, a first glue impregnation tank 12, and a second glue impregnation tank 15. The fiber layer is disposed on the raw fabric storage roller 1. The first glue impregnation tank 3 is equipped with a rotating first steering roller 13, and the second glue impregnation tank 6 is equipped with a rotating second steering roller 16. The first glue impregnation tank 12 is used for preliminary glue impregnation, and the second glue impregnation tank 6 is used for secondary glue impregnation. When magnetic vulcanized fabric needs to be made, neodymium iron boron particles are added to the second glue impregnation tank 6 as needed.

[0039] The vulcanizing unit includes an upper heat-conducting film circulating conveyor roller group and a lower heat-conducting film circulating conveyor roller group. The upper heat-conducting film circulating conveyor roller group is positioned above the adhesive-coated fabric 11. The upper heat-conducting film circulating conveyor roller group includes an upper pressure roller 18, an upper separation roller 26, an upper heat-conducting film guide roller 19, and an upper heat-conducting film 22 wound around the upper pressure roller, upper separation roller, and upper heat-conducting film guide roller. The upper heat-conducting film between the upper pressure roller and the upper separation roller is in close contact with the upper surface of the fabric. The lower heat-conducting film circulating conveyor roller group includes a lower pressure roller 36, a lower separation roller 27, lower heat-conducting film guide rollers 28 and 35, and a lower heat-conducting film guide roller 25 wound around the lower pressure roller, lower separation roller, and lower heat-conducting film guide roller. The heat-conducting film 31 is tightly bonded to the lower surface of the fabric between the lower pressure roller and the lower separation roller. To avoid damaging the fiber layer after impregnation, the upper pressure roller, upper separation roller, lower pressure roller, and lower separation roller all have a rubber layer. An annular conveyor belt is set below the lower heat-conducting film and is in close contact with the lower heat-conducting film. The annular conveyor belt includes a conveyor belt body, a first conveyor wheel 27, and a second conveyor wheel 34. A support platform 33 with heating function is set at the bottom of the upper conveying surface of the conveyor belt body to support the upper conveying surface. A strip electromagnet 32 ​​is set below the support platform. A hopper 37 with the discharge port facing downward is set above the front end of the annular conveyor belt to hold steel powder.

[0040] In this invention, the vulcanized fabric processing apparatus involves dipping the fiber layer in adhesive. During vulcanization in the vulcanization unit, a strip electromagnet is energized as needed. Steel powder at a temperature of 150-200°C flowing from the hopper is attracted by the electromagnet, increasing the pressure on the lower heat-conducting film. This presses the rubber firmly onto the fiber layer, accelerating its wetting and evenly embedding it into the fabric. Simultaneously, vulcanization occurs gradually, increasing the strength of the vulcanized fabric. Existing vulcanization apparatuses use an upper and lower roller extrusion method during vulcanization, which can easily damage some electronic components. In contrast, this vulcanized fabric processing apparatus uses a non-upper and lower roller hard extrusion method, which is more friendly to electronic components and can process vulcanized fabrics with complex structures.

[0041] In addition, the vulcanized fabric processing apparatus of this embodiment also includes a steel powder collection and heating mechanism, which includes a magnetic collection unit, a transfer unit, and a heating unit. The magnetic collection unit is located above the bar electromagnet and the demagnetizing unit, and includes a rotating shaft 40, a plurality of L-shaped first metal rods 41 arranged along the axis of the rotating shaft, a positive conductive cylinder 42 that is rubbed with the brush of the first metal rod, a block electromagnet 39 connected to the end of the first metal rod, a second metal rod 44 connected to the corresponding block electromagnet 39, and a negative conductive cylinder 43 that is rubbed with the brush of the free end of the second metal rod. The negative conductive cylinder has a power-off gap 45. Both the first metal rod and the second metal rod include an electric arc parallel to the axis of the rotating shaft. The connecting part and the right-angle bend connecting to the block electromagnet, the bend of the first metal rod and the second metal rod form the block electromagnet support rod 38; the transfer unit includes an L-shaped collection trough 24 and a first conveyor belt 23 disposed in the collection trough, the bottom surface of the collection trough is a slope that is lower in the front and higher in the back, the first conveyor belt is disposed along the inclined trough wall of the collection trough, which facilitates the collection of steel powder and facilitates the first conveyor belt to collect and transport the steel powder to the heating trough; the heating unit includes a heating trough 21 and a second conveyor belt 20 disposed in the heating trough, the lower end of the first conveyor belt is located at the bottom of the collection trough and the upper end is located above the rear end of the heating trough, the lower end of the second conveyor belt is located at the bottom of the rear end of the heating trough and the upper end of the second conveyor belt is located above the hopper 37.

[0042] The steel powder collection and heating mechanism allows steel powder passing through the strip electromagnet to be collected by the magnetic collection unit. When the block electromagnet is above the transfer unit, the corresponding block electromagnet is de-energized, and the steel powder falls into the transfer unit. It is then sent to the heating unit via the first conveyor belt for heating with heating oil, and then returned to the hopper via the second conveyor belt, forming a cycle. This improves the utilization rate of steel powder and greatly saves the amount of steel powder used.

[0043] In this embodiment, a demagnetizing unit is provided behind the strip electromagnet. The demagnetizing unit is existing technology and will not be described in detail here. When magnetic vulcanized cloth needs to be produced, neodymium iron boron microparticles are added to the second adhesive impregnation tank. After the fiber layer is impregnated in the second adhesive impregnation tank, it is vulcanized in the vulcanization unit. Due to the action of the strip electromagnet during vulcanization, the vulcanized cloth will have a certain degree of magnetism as a whole. The demagnetizing unit behind the strip electromagnet can demagnetize the vulcanized cloth so that it can be magnetized in subsequent processes according to the magnitude of the magnetism and the needs of the magnetized areas. At the same time, it prevents the vulcanized cloth, whose magnetic force is greatly enhanced due to its magnetism, from adsorbing onto the magnetic collection unit.

[0044] It should be noted that the demagnetizing unit is located below the magnetic collecting unit and is longer than the magnetic collecting unit. This is so that the vulcanized cloth is demagnetized before reaching the magnetic collecting unit, preventing the vulcanized cloth, whose magnetic force is greatly enhanced due to its magnetism, from adsorbing onto the magnetic collecting unit. After passing through the magnetic collecting unit, a second demagnetization is performed to eliminate the influence of the magnetic collecting unit on the secondary magnetization of the vulcanized cloth.

[0045] The vulcanized fabric processing method according to the vulcanized fabric processing apparatus of Example 3 is as follows: Figures 1-6 As shown, it includes the following steps:

[0046] Step 1: Blend fibers and conductive metal wires to form a fiber layer;

[0047] Step 2: Impregnate the fiber layer in the first and second adhesive impregnation tanks respectively to form an upper rubber layer, a middle fiber impregnation layer and a lower rubber layer.

[0048] Step 3: The resin-impregnated fiber layer is fed into the vulcanization unit for vulcanization. At the same time, the bar electromagnet is turned on to tightly adsorb the heated steel powder flowing out of the hopper onto the upper heat-conducting film, thereby tightly pressing the resin-impregnated fiber layer and vulcanizing the fiber layer.

[0049] Step 4: Steel powder is collected by magnetic collection unit and sent to transfer unit. It is then sent to heating unit for heating and returned to hopper. The vulcanized material is distributed in collection unit after vulcanization.

[0050] The vulcanized fabric processing method utilizes a vulcanized fabric processing device to conveniently and efficiently process the required complex structure of vulcanized fabric.

[0051] Furthermore, it should be noted that the shapes and names of the parts and components described in the specific embodiments described in this specification may differ. All equivalent or simple variations made to the structure, features, and principles described in this patent concept are included within the protection scope of this patent. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the structure of this invention or exceed the scope defined in these claims, they should all fall within the protection scope of this invention.
