Description

Technical Field

[0001] This application relates to the field of transportation technology, and in particular to a method for recycling the rim of a non-pneumatic tire and the rim of a non-pneumatic tire. Background Technology

[0002] Non-pneumatic tires, such as spoked non-pneumatic tires, have attracted widespread attention in the transportation sector in recent years as an innovative tire design. Compared with traditional pneumatic tires, these tires exhibit significant advantages due to their unique structure and material selection. Spoked non-pneumatic tires mainly consist of three parts: the tread, the spokes, and the rim. The clever use of adhesive technology to fit these three parts together ensures the tire's stability and durability.

[0003] During tire manufacturing, the spoke material is tightly bonded to the tread and rim using precise bonding technology. This bonding method not only ensures the overall strength of the tire but also allows the tire to better distribute force when impacted, protecting the safety of the vehicle and its passengers.

[0004] However, despite the many advantages of spoked non-pneumatic tires, there are also some challenges in their use. Because the tire tread is the part that directly contacts the ground, it bears the brunt of wear. Over time, the tread gradually wears down until it fails. At this point, due to the tire's structural characteristics, the user needs to replace the entire wheel, not just the tread, increasing maintenance costs. Summary of the Invention

[0005] This application provides a method for recycling the hub of a non-pneumatic tire and the hub of a non-pneumatic tire, which can separate the spokes and the hub, facilitating the repeated recycling of the hub.

[0006] In a first aspect, embodiments of this application provide a method for recycling the rim of a non-pneumatic tire, the method comprising:

[0007] Place the damaged, non-pneumatic tire with a normal rim onto the cutting equipment;

[0008] The steps described above allow you to place a damaged, non-pneumatic tire with an intact rim onto specialized cutting equipment. This equipment typically employs high-precision, high-efficiency cutting technology to ensure safety and accuracy during the cutting process.

[0009] The non-pneumatic tire is cut off by the cutting device to obtain a wheel hub with remaining residual spokes to be processed.

[0010] The above steps involve cutting off all the spokes of a non-pneumatic tire using a cutting device. Spokes are an important component of non-pneumatic tires, but they need to be separated from the rim during recycling. After cutting the spokes, a rim with residual spokes is obtained for further processing.

[0011] The remaining spokes on the hub to be treated are easily detachable;

[0012] The steps described above facilitate the removal of residual spokes from the wheel hub. This step aims to reduce the difficulty of subsequently peeling off the residual spokes. Specific methods may include heating, chemical treatment, and other approaches to ensure that the residual spokes can be easily removed from the wheel hub.

[0013] Cut off the remaining spokes after the easy-to-disassemble process;

[0014] The above steps allow for the cutting of any remaining spokes after the easy-to-disassemble process. This step further reduces the size and number of remaining spokes, facilitating subsequent stripping work.

[0015] Use a stripping device to remove the remaining spokes;

[0016] The above steps can be performed using a specialized peeling device to remove the remaining spokes. These devices typically employ advanced technologies such as robotic arms and suction cups to precisely peel the remaining spokes from the hub. During the peeling process, strict control of force and speed is necessary to avoid damaging the hub.

[0017] The separated wheel hubs are shot blasted and polished.

[0018] The above steps allow for shot blasting and polishing of the removed wheel hubs. Shot blasting removes rust, dirt, and other impurities from the wheel hub surface; polishing makes the surface smoother and more aesthetically pleasing. After these two steps, the wheel hubs can be reused.

[0019] In some examples, the easy-to-disassemble treatment is achieved by heating the part of the wheel hub to be treated, excluding the hub itself, to soften it.

[0020] Alternatively, the easy-to-disassemble method involves dissolving the adhesive between the wheel hub and spokes using a pre-set solvent.

[0021] Specifically, the methods for easy disassembly include, but are not limited to, the two mentioned above:

[0022] One easy-to-disassemble method involves heating the wheel hub to soften the rest of the wheel. During heating, the material used for the spokes gradually softens, while the hub, due to its special material and design, maintains high hardness and stability. This allows operators to easily peel the hub from the softened spokes, achieving effective separation. This method is simple, low-cost, and suitable for large-scale applications.

[0023] Another easy-to-disassemble method involves using a pre-prepared solvent to dissolve the adhesive between the wheel hub and spokes. During tire manufacturing, a special adhesive is typically used to connect the wheel hub and spokes. This adhesive swells and dissolves under the influence of a specific solvent, weakening the connection between the hub and spokes. Operators can easily peel the wheel hub from the spokes by simply immersing it in the pre-prepared solvent for a period of time. This method requires precise control over the type and concentration of adhesive, but it achieves a more thorough separation.

[0024] In some examples, the step of easily removing residual spokes on the hub to be treated includes:

[0025] The wheel hub to be processed is placed in the heating device;

[0026] The aforementioned process involves placing the wheel hub to be processed into a dedicated heating device. This device employs advanced temperature control technology to ensure the uniformity and stability of the heating process. Furthermore, the device's user interface is simple and intuitive, allowing operators to quickly learn how to use it.

[0027] Adjust the ambient temperature of the wheel hub to be treated to 120℃-300℃ and maintain it for 10min-120min.

[0028] The above allows for adjustment of the ambient temperature of the wheel hub to be treated. According to research and experimental data, adjusting the ambient temperature to 120℃-300℃ and maintaining it for 10-120 minutes can minimize the adhesion between the spokes and the wheel hub, thus facilitating the removal of the hub. This process is not only efficient but also environmentally friendly, as the exhaust gases generated during heating can be treated to meet emission standards.

[0029] In some examples, the step of cutting the remaining spokes after the easy-to-disassemble process includes:

[0030] The wheel hub to be processed is removed while it is still hot after being fully heated, while the remaining spokes remain in a softened state.

[0031] The above steps may involve using specialized heating equipment to evenly heat the wheel hub. During this process, the heating time and temperature must be strictly controlled to ensure the wheel hub reaches the ideal softening state. Once the wheel hub is fully heated, it can be removed while still hot. At this point, the remaining spokes are softened, ready for the subsequent cutting. The softened remaining spokes are then cut.

[0032] The above steps allow for the cutting of any remaining spokes during the softening process. This step requires high-precision cutting equipment. Such equipment is fast, accurate, and stable, ensuring cutting quality while minimizing damage to the wheel hub. This step allows us to easily remove the remaining spokes from the wheel hub, laying the foundation for its reuse.

[0033] In some examples, the step of stripping the residual spokes with a stripping device includes:

[0034] The softened and cut residual spokes and corresponding adhered hubs are placed into the peeling device;

[0035] In the above steps, the softened and pre-cut residual spokes and the hub to which they adhere can be placed into the peeling device. The softening treatment here is to reduce the adhesion strength between the spokes and the hub, making the peeling process smoother.

[0036] Before the remaining spokes are fully hardened, the remaining spokes are peeled off to obtain the hub.

[0037] In the above steps, the stripping device precisely removes the remaining spokes before they have fully hardened. During this process, the stripping device utilizes advanced robotic arms and sensor technology to ensure the stripping operation is both accurate and rapid. In this way, the wheel hub is completely removed from the remaining spokes, preserving its original integrity and reusability.

[0038] In some examples, the step of easily removing residual spokes on the hub to be treated includes:

[0039] The wheel hub to be treated is placed in the immersion equipment;

[0040] The above steps involve placing the wheel hub to be treated into the immersion equipment. This step ensures that the wheel hub has sufficient contact with the solvent during subsequent processing, thereby achieving a better peeling effect. In the immersion equipment, the wheel hub is placed stably to ensure that it does not move or tilt during the immersion process.

[0041] Add a preset solvent to the soaking device and maintain the soaking state for at least 60 minutes.

[0042] The above steps involve adding a pre-selected solvent to the soaking equipment. This solvent is carefully selected and formulated to quickly penetrate the connection between the spokes and the hub, thereby weakening the bond between them. Simultaneously, the amount of solvent added is strictly controlled to ensure that the solvent concentration and temperature remain stable during the soaking process, which lasts for at least 60 minutes.

[0043] In some examples, the step of cutting the remaining spokes after the easy-to-disassemble process includes:

[0044] After the wheel hub has been fully soaked, it is removed, and the adhesive between the remaining spokes and the wheel hub fails.

[0045] In the steps described above, the thoroughly soaked wheel hub can be removed. This soaking process utilizes a specific chemical solvent to gradually break down the adhesive between the remaining spokes and the hub. The choice of this chemical solvent is crucial; it needs to be able to specifically disrupt the molecular structure of the adhesive without damaging the hub material. Carefully selected and experimentally validated solvents ensure the efficiency and safety of the entire treatment process.

[0046] Cut off any remaining spokes from adhesive failure.

[0047] In the steps described above, the remaining spokes due to adhesive failure can be cut. This step requires high-precision cutting equipment to ensure accuracy and efficiency. During the cutting process, the equipment precisely cuts the remaining spokes according to preset parameters, such as cutting depth, angle, and speed. After cutting, the connection between the spokes and the hub is completely severed, and the hub can be easily peeled off.

[0048] In some examples, the preset solvent includes at least one of ketones and organic compounds, which is capable of swelling and dissolving the adhesive between the hub and the spokes.

[0049] The core of the aforementioned recycling method lies in using a pre-selected solvent to melt and dissolve the adhesive between the wheel hub and spokes. Specifically, the pre-selected solvent mainly includes at least one of ketones and organic compounds. These solvents have strong dissolving power and can effectively penetrate into the adhesive between the wheel hub and spokes, destroying its molecular structure and thus achieving separation.

[0050] In practice, the non-pneumatic tire is first placed in specific equipment. Then, by controlling parameters such as temperature and pressure, a pre-set solvent is applied to the adhesive between the hub and spokes. As the solvent penetrates and dissolves the material, the connection between the hub and spokes gradually weakens until they are completely separated. At this point, the hub can be easily peeled off, facilitating subsequent recycling and reuse.

[0051] In some examples, the non-pneumatic tire includes a tread, spokes, and a hub from the outside to the inside, and the spokes include an outer ring, spokes, and an inner ring from the outside to the inside, with the tread connected to the outer ring and the hub connected to the inner ring;

[0052] After the cutting device cuts off all the spokes of the non-pneumatic tire, the non-pneumatic tire will be divided into two parts. The first part includes the tread, the outer ring, and some spokes located inside the outer ring. The second part includes some spokes located outside the inner ring, the inner ring, and the hub. The hub to be processed is the second part.

[0053] A non-pneumatic tire typically consists of three parts from the outside in: the tread, the spokes, and the rim. Among these, the spokes, as the key component connecting the tread and the rim, are particularly important in their design.

[0054] Specifically, the wheel spokes consist of the outer ring, spokes, and inner ring from the outside in. The outer ring is the outermost layer of the spokes, tightly connected to the tire tread, and bears the various forces exerted by the vehicle during driving. The spokes, like a bridge, connect the outer and inner rings, ensuring the overall stability and load-bearing capacity of the tire. The inner ring connects to the rim, providing support and fixation.

[0055] Specialized cutting equipment is needed when specific processing is required on non-pneumatic tires, such as replacing the rim or repairing a part. This equipment can precisely cut off all the spokes, dividing the non-pneumatic tire into two parts.

[0056] The first part mainly includes the tread, outer ring, and some spokes located inside the outer ring. This part of the structure retains the basic shape and appearance of the tire and can continue to be used. The second part includes some spokes located outside the inner ring, the inner ring, and the rim. After this part of the structure is cut, the rim becomes the object to be processed.

[0057] Secondly, this application provides a hub for a non-pneumatic wheel, wherein the hub of the non-pneumatic wheel can be recycled using the aforementioned non-pneumatic tire hub recycling method.

[0058] After recycling the rims of non-pneumatic tires using the aforementioned method, the rims can be reused. This not only reduces resource waste and environmental pollution but also brings significant economic benefits to businesses. Specifically, the rims of most non-pneumatic tires can still be recycled and reused after damage. Furthermore, this recycling method has advantages such as simple operation, high efficiency, and good safety. Attached Figure Description

[0059] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0060] Figure 1 This is a schematic flowchart of a method for recycling the hub of a non-pneumatic tire according to an embodiment of this application. Detailed Implementation

[0061] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0062] Non-pneumatic tires, such as spoked non-pneumatic tires, have attracted widespread attention in the transportation sector in recent years as an innovative tire design. Compared with traditional pneumatic tires, these tires exhibit significant advantages due to their unique structure and material selection. Spoked non-pneumatic tires mainly consist of three parts: the tread, the spokes, and the rim. The clever use of adhesive technology to fit these three parts together ensures the tire's stability and durability.

[0063] In terms of material selection, the tread of non-pneumatic tires mainly uses olefin rubbers such as natural rubber, styrene-butadiene rubber, butadiene rubber, and isoprene rubber. These materials not only have excellent elasticity and wear resistance, but also maintain stable performance under various complex climates and road conditions. Meanwhile, the rim, as the supporting part of the tire, mainly uses alloy rims and steel rims, which have high strength and corrosion resistance, ensuring the safety of the tire during long-term use.

[0064] During tire manufacturing, the spoke material is tightly bonded to the tread and rim using precise bonding technology. This bonding method not only ensures the overall strength of the tire but also allows the tire to better distribute force when impacted, protecting the safety of the vehicle and its passengers.

[0065] However, despite the many advantages of spoked non-pneumatic tires, there are also some challenges in their use. Because the tire tread is the part that directly contacts the ground, it bears the brunt of wear. Over time, the tread gradually wears down until it fails. At this point, due to the tire's structural characteristics, the user needs to replace the entire wheel, not just the tread, increasing maintenance costs.

[0066] With increasing environmental awareness and the growing importance of sustainable development, the tire recycling industry is undergoing a technological revolution. Among the many innovative technologies, a new method focusing on the recycling of non-pneumatic tire rims is particularly noteworthy. This method not only solves many problems in traditional tire recycling but also provides a completely new solution for the reuse of rims. Below, we will introduce this innovative non-pneumatic tire rim recycling method in detail.

[0067] First, it's necessary to clarify the advantages of non-pneumatic tires compared to traditional pneumatic tires. Due to their characteristics such as not requiring inflation, structural stability, and wear resistance, non-pneumatic tires are increasingly widely used in automobiles, electric vehicles, bicycles, and other fields. However, when these tires are damaged, how to efficiently and environmentally recycle the rims has become a pressing issue.

[0068] To solve the above technical problems, please refer to Figure 1 As shown, the first aspect of this application proposes a method for recycling the hub of a non-pneumatic tire, which can separate the spokes and the hub, facilitating the repeated recycling of the hub.

[0069] Reference Figure 1 As shown, in some examples, embodiments of this application provide a method for recycling the rims of non-pneumatic tires. Specifically, the spokes and rim can be separated to facilitate the repeated recycling of the rim, aiming to achieve the recycling of rims and reduce resource waste and environmental pollution. The method includes:

[0070] Step S100: Place the damaged, non-pneumatic tire with a normal rim onto the cutting equipment;

[0071] The steps described above allow you to place a damaged, non-pneumatic tire with an intact rim onto specialized cutting equipment. This equipment typically employs high-precision, high-efficiency cutting technology to ensure safety and accuracy during the cutting process.

[0072] Step S200: Cut off all the spokes of the non-pneumatic tire using a cutting device to obtain a wheel hub with the remaining residual spokes;

[0073] The above steps involve cutting off all the spokes of a non-pneumatic tire using a cutting device. Spokes are an important component of non-pneumatic tires, but they need to be separated from the rim during recycling. After cutting the spokes, a rim with residual spokes is obtained for further processing.

[0074] Step S300: Perform easy removal of the remaining spokes on the wheel hub to be treated;

[0075] The steps described above facilitate the removal of residual spokes from the wheel hub. This step aims to reduce the difficulty of subsequently peeling off the residual spokes. Specific methods may include heating, chemical treatment, and other approaches to ensure that the residual spokes can be easily removed from the wheel hub.

[0076] Step S400: Cut the remaining spokes after the easy-to-disassemble process;

[0077] The above steps allow for the cutting of any remaining spokes after the easy-to-disassemble process. This step further reduces the size and number of remaining spokes, facilitating subsequent stripping work.

[0078] Step S500: Use a stripping device to strip the remaining spokes;

[0079] The above steps can be performed using a specialized peeling device to remove the remaining spokes. These devices typically employ advanced technologies such as robotic arms and suction cups to precisely peel the remaining spokes from the hub. During the peeling process, strict control of force and speed is necessary to avoid damaging the hub.

[0080] Step S600: Perform shot blasting and polishing on the stripped wheel hub.

[0081] The above steps allow for shot blasting and polishing of the removed wheel hubs. Shot blasting removes rust, dirt, and other impurities from the wheel hub surface; polishing makes the surface smoother and more aesthetically pleasing. After these two steps, the wheel hubs can be reused.

[0082] Statistical data shows that using this non-pneumatic tire rim recycling method, the rim recycling rate can reach over 90%. This means that most non-pneumatic tires, even after damage, still have rims that can be recycled and reused. This not only reduces resource waste and environmental pollution but also brings significant economic benefits to businesses.

[0083] Furthermore, this recycling method boasts advantages such as simple operation, high efficiency, and good safety. In practical applications, the recycling process can be appropriately adjusted and optimized according to different tire types and degrees of damage. This gives the recycling method broad application prospects and market potential.

[0084] In summary, the non-pneumatic tire hub recycling method provided in this application is an innovative, environmentally friendly, and efficient solution. It not only enables the recycling of hubs but also brings economic and social benefits to businesses.

[0085] In some examples, the easy-to-disassemble treatment involves heating the wheel hub to soften the rest of the wheel hub, making it easier to peel it off.

[0086] Alternatively, an easy-to-disassemble method involves using a pre-set solvent to melt and expand the adhesive between the wheel hub and spokes, making it convenient to peel the wheel hub off.

[0087] Unlike traditional pneumatic tires, non-pneumatic tires do not require internal air pressure to maintain their shape and performance, thus offering greater durability and safety. However, this also presents challenges for rim recycling, as the connection between the rim and spokes is often more complex.

[0088] To address this challenge, an innovative wheel hub recycling method has been proposed. The core of this method lies in achieving efficient separation of the spokes and hub through a specific easy-to-disassemble process. Specifically, the easy-to-disassemble process includes, but is not limited to, the two methods mentioned above:

[0089] One easy-to-disassemble method involves heating the wheel hub to soften the rest of the wheel. During heating, the material used for the spokes gradually softens, while the hub, due to its special material and design, maintains high hardness and stability. This allows operators to easily peel the hub from the softened spokes, achieving effective separation. This method is simple, low-cost, and suitable for large-scale applications.

[0090] Another easy-to-disassemble method involves using a pre-prepared solvent to dissolve the adhesive between the wheel hub and spokes. During tire manufacturing, a special adhesive is typically used to connect the wheel hub and spokes. This adhesive swells and dissolves under the influence of a specific solvent, weakening the connection between the hub and spokes. Operators can easily peel the wheel hub from the spokes by simply immersing it in the pre-prepared solvent for a period of time. This method requires precise control over the type and concentration of adhesive, but it achieves a more thorough separation.

[0091] It is worth mentioning that the wheel hub recycling method described in this application not only improves recycling efficiency but also promotes the sustainable use of resources. By recycling and reusing wheel hubs, reliance on new materials can be reduced, production costs can be lowered, and environmental impact can be minimized. Adopting this recycling method could save millions of tons of steel and rubber materials annually, which is of great significance for promoting the development of green industries.

[0092] In summary, this method for recycling non-pneumatic tire rims is an innovative and practical solution. It not only achieves efficient separation of the spokes and rim but also promotes the sustainable use of resources.

[0093] In some examples, the steps for easily removing residual spokes on the wheel hub include:

[0094] Step S310: Place the wheel hub to be processed into the heating device;

[0095] In step S310, the wheel hub to be processed can be placed in a dedicated heating device. This heating device employs advanced temperature control technology to ensure the uniformity and stability of the heating process. Furthermore, the device's user interface is simple and clear, allowing operators to quickly learn how to use it.

[0096] Step S320: Adjust the ambient temperature of the wheel hub to be treated to 120℃-300℃ and maintain it for 10min-120min. This will facilitate the removal of the wheel hub.

[0097] In step S320, the ambient temperature of the wheel hub to be treated can be adjusted. Based on research and experimental data, adjusting the ambient temperature to 120℃-300℃ and maintaining it for 10-120 minutes can minimize the adhesion between the spokes and the wheel hub, thus facilitating the removal of the wheel hub. This process is not only efficient but also environmentally friendly, as the exhaust gases generated during heating can be treated to meet emission standards.

[0098] It's important to clarify that the core of this recycling method lies in the easy disassembly of residual spokes on the wheel hub. This is a crucial step because it directly affects the integrity of the wheel hub and the possibility of subsequent reuse. Through the steps described above, the efficiency and environmental friendliness of the processing can be ensured.

[0099] It's worth noting that this recycling method has demonstrated outstanding performance in practical applications. For example, the wheel hub recycling rate using this method is over 95%, and the recycled wheels are of stable and reliable quality, gaining widespread market acceptance. Furthermore, this method significantly reduces waste and pollutant emissions generated during traditional tire recycling processes, helping to improve a company's environmental image and economic benefits.

[0100] In summary, this method of recycling non-pneumatic tire rims has significant advantages and potential. It not only enables efficient recycling and reuse of rims, reducing resource waste and environmental pollution, but also lowers production costs and improves economic efficiency.

[0101] The ambient temperature mentioned above may also include, but is not limited to, 130℃, 140℃, 150℃, 200℃, 230℃, 250℃, and 280℃. The time parameters mentioned above may also include, but are not limited to, 11min, 15min, 20min, 25min, 30min, 60min, 80min, 100min, and 110min.

[0102] In some examples, the steps of cutting off the remaining spokes after easy disassembly include:

[0103] Step S410: Remove the fully heated wheel hub while it is still hot, keeping the remaining spokes in a softened state;

[0104] In step S410, specialized heating equipment may be used to uniformly heat the wheel hub. During this process, the heating time and temperature must be strictly controlled to ensure the wheel hub reaches the ideal softening state. Once the wheel hub is fully heated, it can be removed while still hot; at this point, the remaining spokes are softened, preparing it for the subsequent cutting.

[0105] Step S420: Cut the softened residual spokes to facilitate the removal of the wheel hub.

[0106] In step S420, the softened residual spokes can be cut. This step requires high-precision cutting equipment. Such equipment is fast, accurate, and stable, ensuring cutting quality while minimizing damage to the wheel hub. This step allows us to easily peel the residual spokes off the wheel hub, laying the foundation for its reuse.

[0107] The core of this non-pneumatic tire rim recycling method lies in the precise and efficient cutting of the remaining rim spokes after easy disassembly. The rim to be processed needs to be thoroughly heated to a certain temperature, so that the remaining spokes remain in a softened state. This step is crucial because it not only ensures the smooth progress of subsequent cutting but also reduces damage to the rim itself during the cutting process.

[0108] It's worth noting that this method of recycling non-pneumatic tire rims not only has environmental benefits but also offers certain economic advantages. According to relevant research data, rims recycled using this method can be reused after processing, with performance and lifespan nearly identical to new rims. This means that this method can effectively reduce production costs, improve resource utilization, and achieve a win-win situation for both environmental protection and economic benefits.

[0109] Furthermore, this recycling method has broad application prospects. With the rapid development of electric vehicles and new energy vehicles, the market demand for non-pneumatic tires, as a new type of tire, is constantly expanding. Correspondingly, the issue of wheel rim recycling and reuse is becoming increasingly prominent. Therefore, this non-pneumatic tire wheel rim recycling method has enormous market potential and application value.

[0110] This non-pneumatic tire rim recycling method not only enables precise separation of the spokes from the rim, making it possible to reuse the rim, but also effectively reduces production costs, improves resource utilization, and promotes the sustainable development of the automotive industry.

[0111] In some examples, the step of stripping residual spokes using a stripping device includes:

[0112] Step S510: Place the softened and cut residual spokes and the corresponding adhered hub into the peeling device;

[0113] In the above steps, the softened and pre-cut residual spokes and the hub to which they adhere can be placed into the peeling device. The softening treatment here is to reduce the adhesion strength between the spokes and the hub, making the peeling process smoother.

[0114] Step S520: Before the remaining spokes are fully hardened, the remaining spokes are peeled off to obtain the wheel hub. This makes it easier to peel off the wheel hub.

[0115] In the above steps, the stripping device precisely removes the remaining spokes before they have fully hardened. During this process, the stripping device utilizes advanced robotic arms and sensor technology to ensure the stripping operation is both accurate and rapid. In this way, the wheel hub is completely removed from the remaining spokes, preserving its original integrity and reusability.

[0116] It is worth noting that this recycling method is not only highly efficient but also has significant environmental value. Since wheel rims are a crucial component of tires and their materials are valuable, recycling and reusing them can significantly reduce resource consumption and environmental pollution during tire production. Statistical data shows that using this recycling method, the wheel rim recycling rate reaches over 90%, effectively reducing the environmental impact of tire waste.

[0117] In some examples, the steps for easily removing residual spokes on the wheel hub include:

[0118] Step S330: Place the wheel hub to be treated in the immersion equipment;

[0119] The above steps involve placing the wheel hub to be treated into the immersion equipment. This step ensures that the wheel hub has sufficient contact with the solvent during subsequent processing, thereby achieving a better peeling effect. In the immersion equipment, the wheel hub is placed stably to ensure that it does not move or tilt during the immersion process.

[0120] Step S340: Add the preset solvent to the soaking device and maintain the soaking state for at least 60 minutes.

[0121] The above steps involve adding a pre-selected solvent to the soaking equipment. This solvent is carefully selected and formulated to quickly penetrate the connection between the spokes and the hub, thereby weakening the bond between them. Simultaneously, the amount of solvent added is strictly controlled to ensure that the solvent concentration and temperature remain stable during the soaking process, which lasts for at least 60 minutes.

[0122] During the soaking process, the solvent gradually softens the connection between the spokes and the hub. Over time, the bonding force between the spokes and hub weakens, eventually allowing the spokes to separate from the hub. At this point, the spokes can be easily peeled off the hub with a gentle pull.

[0123] It's worth noting that this wheel hub recycling method is not only simple and efficient to operate, but also environmentally friendly. Thanks to the use of special solvents and soaking technology, the entire process produces no harmful waste gas, wastewater, or waste residue, fully meeting environmental protection requirements. Furthermore, the detached wheel spokes can be reused, further improving resource utilization.

[0124] This wheel hub recycling method achieves a recycling rate of over 90%, and the recycled wheel hubs maintain good quality, fully meeting the requirements for reuse. Furthermore, compared to traditional tire recycling methods, this wheel hub recycling method saves significant energy and costs, bringing considerable economic benefits to businesses.

[0125] This method of recycling non-pneumatic tire rims not only has significant environmental and economic benefits, but also provides a new approach and method for the tire recycling industry.

[0126] In some examples, the steps of cutting off the remaining spokes after easy disassembly include:

[0127] Step S430: Remove the fully soaked wheel hub; the adhesive between the remaining spokes and the wheel hub will fail.

[0128] In the steps described above, the thoroughly soaked wheel hub can be removed. This soaking process utilizes a specific chemical solvent to gradually break down the adhesive between the remaining spokes and the hub. The choice of this chemical solvent is crucial; it needs to be able to specifically disrupt the molecular structure of the adhesive without damaging the hub material. Carefully selected and experimentally validated solvents ensure the efficiency and safety of the entire treatment process.

[0129] Step S440: Cut off the remaining spokes from the adhesive failure.

[0130] In the steps described above, the remaining spokes due to adhesive failure can be cut. This step requires high-precision cutting equipment to ensure accuracy and efficiency. During the cutting process, the equipment precisely cuts the remaining spokes according to preset parameters, such as cutting depth, angle, and speed. After cutting, the connection between the spokes and the hub is completely severed, and the hub can be easily peeled off.

[0131] The advantages of this recycling method lie in its efficiency and environmental friendliness. By precisely controlling the use of chemical solvents and the operation of the cutting equipment, the entire process can complete the recycling of a large number of wheel hubs in a short time. Furthermore, due to the targeted nature of the chemical solvents and the precision of the cutting equipment, the wheel hubs suffer minimal damage during recycling, retaining a high degree of reuse value. In addition, this method reduces environmental pollution and resource waste, aligning with the requirements of sustainable development.

[0132] In some examples, the preset solvent includes at least one of ketones and organic compounds, which is capable of swelling and dissolving the adhesive between the wheel hub and the spokes.

[0133] The core of the aforementioned recycling method lies in using a pre-selected solvent to melt and dissolve the adhesive between the wheel hub and spokes. Specifically, the pre-selected solvent mainly includes at least one of ketones and organic compounds. These solvents have strong dissolving power and can effectively penetrate into the adhesive between the wheel hub and spokes, destroying its molecular structure and thus achieving separation.

[0134] In practice, the non-pneumatic tire is first placed in specific equipment. Then, by controlling parameters such as temperature and pressure, a pre-set solvent is applied to the adhesive between the hub and spokes. As the solvent penetrates and dissolves the material, the connection between the hub and spokes gradually weakens until they are completely separated. At this point, the hub can be easily peeled off, facilitating subsequent recycling and reuse.

[0135] It is worth mentioning that this recycling method is not only highly efficient but also environmentally friendly. Because the selected solvent is targeted, it minimizes environmental pollution while ensuring effective dissolution. Furthermore, the recycled wheel hubs can be reused in production after simple processing, thus achieving resource recycling.

[0136] In some examples, a non-pneumatic tire consists of a tread, spokes, and rim from the outside in. The spokes consist of an outer ring, spokes, and an inner ring from the outside in. The tread is connected to the outer ring, and the rim is connected to the inner ring.

[0137] After the cutting equipment cuts off all the spokes of the non-pneumatic tire, the non-pneumatic tire will be divided into two parts. The first part includes the tread, the outer ring, and some spokes located inside the outer ring. The second part includes some spokes located outside the inner ring, the inner ring, and the rim. The rim to be processed is the second part.

[0138] A non-pneumatic tire typically consists of three parts from the outside in: the tread, the spokes, and the rim. Among these, the spokes, as the key component connecting the tread and the rim, are particularly important in their design.

[0139] Specifically, the wheel spokes consist of the outer ring, spokes, and inner ring from the outside in. The outer ring is the outermost layer of the spokes, tightly connected to the tire tread, and bears the various forces exerted by the vehicle during driving. The spokes, like a bridge, connect the outer and inner rings, ensuring the overall stability and load-bearing capacity of the tire. The inner ring connects to the rim, providing support and fixation.

[0140] Specialized cutting equipment is needed when specific processing is required on non-pneumatic tires, such as replacing the rim or repairing a part. This equipment can precisely cut off all the spokes, dividing the non-pneumatic tire into two parts.

[0141] The first part mainly includes the tread, outer ring, and some spokes located inside the outer ring. This part of the structure retains the basic shape and appearance of the tire and can continue to be used. The second part includes some spokes located outside the inner ring, the inner ring, and the rim. After this part of the structure is cut, the rim becomes the object to be processed.

[0142] This cutting method not only ensures the integrity and reusability of all parts of the tire, but also significantly improves processing efficiency. According to statistics, using this cutting method to process non-pneumatic tires can save nearly 30% of the time compared to traditional methods. At the same time, because all parts of the tire are fully utilized, it also reduces environmental pollution.

[0143] It's worth noting that some non-pneumatic tires utilize composite materials and advanced manufacturing processes, allowing the spokes to maintain strength while also possessing good flexibility and impact resistance. This design enables non-pneumatic tires to exhibit higher stability and safety when dealing with complex road conditions.

[0144] Secondly, this application provides a non-pneumatic wheel hub, which can be recycled using the non-pneumatic tire hub recycling method described above.

[0145] After recycling non-pneumatic tire rims using the aforementioned method, the rims can be reused. This not only reduces resource waste and environmental pollution but also brings significant economic benefits to businesses. Specifically, the rims of most non-pneumatic tires can still be recycled and reused after damage. Furthermore, this recycling method has advantages such as simple operation, high efficiency, and good safety. In practical applications, the recycling process can be appropriately adjusted and optimized according to different tire types and degrees of damage. This gives this recycling method broad application prospects and market potential.

[0146] The non-pneumatic tire hub recycling method provided in this application is an innovative, environmentally friendly, and efficient solution. It not only enables the recycling of hubs but also brings economic and social benefits to businesses.
