Description

Technical Field

[0001] This invention relates to the technical field of tire processing, and in particular to a device for bonding anti-cutting layers to radial aircraft tires. Background Technology

[0002] Radial aircraft tires, due to their high load, high speed, and high safety requirements, have a more complex and precise structure than ordinary tires. Among them, the anti-cut layer, a key reinforcing structure located between the belt layer and the tread, is mainly made of high-strength, high-modulus aramid fibers and other materials. Its core function is to resist impacts and cuts from runway debris, protecting the underlying belt layer and ensuring the tire's safety. Therefore, the strength, uniformity, and reliability of the interfacial adhesion between the anti-cut layer and the tire matrix (mainly the tread base rubber or belt layer overlay) directly determine the tire's overall performance and service life.

[0003] Currently, in the production of radial tires (including aircraft tires), the bonding of the tread and related components mainly relies on mechanical hot pressing processes. For example, the "tread hot bonding device for radial tire production" disclosed in Chinese patent application CN117841431A uses adjustable-gap extrusion rollers to roll the tread, supplemented by heating (generating fumes) to promote adhesion. These existing technical solutions generally suffer from the following inherent defects: The bonding mechanism is limited, and the interfacial strength has reached a bottleneck: Current technologies mainly rely on the physical effects of heat and mechanical pressure to soften and flow the rubber, causing it to deform and adhere. However, for materials like aramid anti-cutting layers, which have smooth surfaces and are extremely chemically inert, traditional hot pressing is insufficient to form a strong chemical bond and micro-mechanical interlock with the rubber matrix. The rubber cannot fully wet the aramid fiber bundles, resulting in microscopic defects at the interface. Key bonding indicators such as "H-pull-out force" are difficult to further improve, becoming a critical bottleneck limiting the performance and reliability of aircraft tires.

[0004] Significant side effects of process heat: The overall heating applied to promote adhesion (as mentioned in CN117841431A, which generates fumes) can easily damage the high-temperature properties of aramid fibers and may also cause scorching of the rubber compound (early vulcanization), affecting the uniformity of the final product's performance. The generated fumes also require additional purification systems, increasing equipment complexity and environmental costs.

[0005] Lack of specialized treatment for anti-cutting layer characteristics: Existing bonding devices (such as those mentioned in the patent) are mostly general-purpose tread pressing equipment. Their design goal is to adapt to the physical dimensions of different tire sizes and achieve basic compaction, without addressing the core issue of "how to fundamentally improve the extremely difficult interface of aramid-rubber". Their pressure rollers only have the functions of applying pressure and heating, and cannot perform active, molecular-level modification of the interface.

[0006] Vibration and noise issues: Traditional mechanical pressing equipment is prone to vibration and noise during high-speed rolling. If these vibrations are transmitted to the precision forming drum or equipment frame, they may affect the positioning accuracy and long-term stability of the equipment.

[0007] In summary, existing anti-cutting layer bonding technologies for radial tires (especially aircraft tires) are limited by their bonding mechanisms and have reached a bottleneck in pursuing higher interfacial performance. They also suffer from high energy consumption, material damage risks, and a lack of specificity. Therefore, there is an urgent need to develop a new bonding technology and equipment that can actively and efficiently strengthen the interfacial bond between the aramid anti-cutting layer and the rubber matrix without damaging the materials. This would break through existing performance limits and meet the stringent safety and reliability requirements of next-generation high-performance aircraft tires. Summary of the Invention

[0008] To solve the above-mentioned technical problems, the present invention provides a device for bonding the anti-cutting layer of radial aircraft tires.

[0009] The present invention provides a shear-resistant layer bonding device for radial aircraft tires, comprising a base, a forming drum body, and a controller. The forming drum body is disposed at the top of the base, and the controller is disposed at the top of the base. The device also includes: An ultrasonic bonding assembly, mounted on top of a base, is used to bond the anti-cut layer to a tire. Air-cooled components are installed on the ultrasonic bonding components to cool them down. Both the ultrasonic bonding component and the air-cooling component are electrically connected to the controller. In use, the tire is fitted onto the molding drum body, and the anti-cutting layer is initially adhered to the outer sidewall of the tire. The controller operates the ultrasonic bonding component to press the rotating tire and the anti-cutting layer onto the molding drum body. At the same time, the air-cooling component is operated to cool the ultrasonic bonding component, avoiding the limitations of traditional hot pressing or pure mechanical pressing for highly inert interfaces such as aramid-rubber, where the bonding strength has reached a bottleneck and high heat can damage the material.

[0010] Preferably, the ultrasonic bonding assembly includes a crossbeam, a servo electric cylinder, a lifting plate, a light bar, a disc spring, a pressure sensor, a fixed base, vertical plates, and a lifting seat. Two sets of vertical plates are mounted on the top of the base, and the tops of both sets of vertical plates are connected to the bottom of the crossbeam. A servo electric cylinder is mounted on the top of the crossbeam, and the bottom moving end of the servo electric cylinder is connected to the top of the lifting plate. A light bar is mounted on the top of the lifting plate and is slidably connected to the crossbeam. A pressure sensor is mounted on the bottom of the lifting plate, and a fixed base is mounted on the bottom of the pressure sensor. A disc spring is mounted on the bottom of the fixed base, and a lifting seat is mounted on the bottom of the disc spring. An ultrasonic pressure roller assembly is mounted on the bottom of the lifting seat. Both the servo electric cylinder and the ultrasonic pressure roller assembly are electrically connected to a controller. In use, the anti-cutting layer is wrapped around the outside of the tire, and the assembly is activated. The main body of the drum rotates the tire and the anti-cut layer. Then, the controller extends the servo electric cylinder, causing the lifting plate to drive the ultrasonic pressure roller assembly to contact the outer wall of the anti-cut layer under the guidance of the light bar. The disc spring adapts accordingly. When the pressure sensor detects that the pressure of the ultrasonic pressure roller assembly on the anti-cut layer reaches the set value, the servo electric cylinder maintains a constant length. The ultrasonic pressure roller assembly presses the anti-cut layer and the tire together with ultrasonic vibration, utilizing the micro-friction effect to improve the adhesion strength between the tire and the anti-cut layer and avoid damage to the materials from high heat. The disc spring provides a constant and smooth clamping force while isolating harmful vibrations and reducing damage to the servo electric cylinder. It protects the ultrasonic pressure roller assembly from the reverse impact of the tire joint and also buffers the instantaneous force of the ultrasonic pressure roller assembly on the tire.

[0011] Preferably, the ultrasonic pressure roller assembly includes a bearing housing, a hollow rotating roller, a first hollow rotating shaft, a first support plate, an electromagnetic slip ring, an ultrasonic generator, a first cable, a second cable, and a second hollow rotating shaft. Two sets of bearing housings are provided at the bottom of the lifting base. A first hollow rotating shaft is provided on one side of the hollow rotating roller, and a second hollow rotating shaft is provided on the other side of the hollow rotating roller. The first and second hollow rotating shafts are rotatably connected to a set of bearing housings, respectively. A first support plate is provided at the bottom of the lifting base, and an electromagnetic slip ring is provided on the first support plate. An ultrasonic generator is provided at the bottom of the crossbeam. The output end of the ultrasonic generator is connected to the first end of the first cable, and the second end of the first cable is connected to the fixed end of the electromagnetic slip ring. An ultrasonic transducer is installed inside the hollow rotating roller. The input end of the ultrasonic transducer is connected to the first end of the second cable, and the second end of the second cable passes through the second hollow rotating shaft and is connected to the rotating end of the electromagnetic slip ring. In use, when the outer wall of the hollow rotating roller comes into contact with the outer wall of the anti-cutting layer, the forming drum body drives the tire and the anti-cutting layer to rotate, thereby causing the hollow rotating roller to rotate adaptively with the cooperation of two sets of bearing seats. The ultrasonic generator is then activated, causing the ultrasonic transducer inside the hollow rotating roller to vibrate with the cooperation of the first cable, the second cable, and the electromagnetic slip ring, thereby realizing the ultrasonic vibration of the hollow rotating roller. This further realizes the micro-friction effect of the hollow rotating roller on the anti-cutting layer and the tire, improving the adhesion strength between the anti-cutting layer and the tire.

[0012] Preferably, the air-cooled assembly includes a second support plate, a rotary joint, a blower, a telescopic hose, exhaust ports, a dustproof net, and a filter assembly. The second support plate is located at the bottom of the lifting seat, and a rotary joint is mounted on the second support plate. The rotating end of the rotary joint is connected to one end of the first hollow rotating shaft, and the fixed end of the rotary joint is connected to the output end of the telescopic hose. A blower is mounted on the vertical plate, and a filter assembly is located between the blower and the input end of the telescopic hose. Multiple sets of exhaust ports are located on the side of the hollow rotating roller, and each set of exhaust ports contains a dustproof net. When the ultrasonic transducer inside the hollow rotating roller drives the hollow rotating roller to perform ultrasonic vibration, the temperature of the ultrasonic transducer rises, activating the blower. This allows cold air from the outside to enter the hollow rotating roller through the telescopic hose and rotary joint to cool the ultrasonic transducer. The hot air inside the hollow rotating roller is discharged through the multiple exhaust ports. Simultaneously, the dustproof net prevents external dust from entering the hollow rotating roller and adhering to the surface of the ultrasonic transducer, thus improving its service life.

[0013] Preferably, the filter assembly includes a No. 1 tee pipe, an air supply pipe, an air supply valve, a filter box, a sealing cover, and a No. 2 tee pipe. The input end of the No. 1 tee pipe is connected to the output end of the blower. The two sets of output ends of the No. 1 tee pipe are respectively connected to the input ends of two sets of air supply pipes. The output ends of both sets of air supply pipes are connected to the two sets of input ends of the No. 2 tee pipe. The output end of the No. 2 tee pipe is connected to the input end of the telescopic hose. Each set of air supply pipes is equipped with a filter box and two sets of air supply valves. The filter box is located between the two sets of air supply valves. A filter screen is installed inside the filter box. The top of the filter box... The end is equipped with a sealing cover; open the two sets of air supply valves on the first set of air supply pipes and close the two sets of air supply valves on the second set of air supply pipes, so that the filter screen inside the first set of filter boxes filters the dust from the cold air delivered by the blower. After a period of use, when it is necessary to clean the filter screen inside the first set of filter boxes, the operator opens the two sets of air supply valves on the second set of air supply pipes and closes the two sets of air supply valves on the first set of air supply pipes, thereby switching between the two sets of filter boxes. After the operator removes the sealing cover on the first set of filter boxes, the corresponding filter screen is taken out and cleaned, so as to achieve non-stop operation and improve processing efficiency.

[0014] Preferably, it also includes a handle and bolts. The sealing cover is provided with a handle, and the sealing cover is fixedly connected to the filter box by bolts. The bolts improve the connection between the sealing cover and the filter box and facilitate disassembly. At the same time, the operator can move the sealing cover by using the handle, which improves convenience.

[0015] Preferably, it also includes a reinforcing plate, and a reinforcing plate is provided between the vertical plate and the base; the vertical plate and the base are reinforced by the reinforcing plate to improve the connection strength.

[0016] Preferably, the base also includes adjustable feet, and multiple sets of adjustable feet are provided on the base; the multiple sets of adjustable feet cooperate with each other to provide stable support for the base and improve stability.

[0017] Preferably, it also includes a handle cover, on which the handle is fitted; the operator grips the handle with the handle cover, reducing the chance of the handle slipping.

[0018] Preferably, it also includes a support plate, on which the No. 2 tee pipe is provided, and the No. 1 tee pipe is installed on the vertical plate; the support plate reinforces and supports the No. 2 tee pipe, reduces the shaking of the No. 2 tee pipe, and improves the connection firmness.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: In use, the tire is fitted onto the molding drum body, the anti-cutting layer is initially pasted onto the outer sidewall of the tire, and the ultrasonic bonding component is operated by the controller to press the rotating tire and the anti-cutting layer on the molding drum body together. At the same time, the air-cooling component is operated to cool down the ultrasonic bonding component, avoiding the bottleneck of the bonding strength of traditional hot pressing or pure mechanical pressing for highly inert interfaces such as aramid-rubber, and the damage to the material caused by high heat.

[0026] In this embodiment, during use, the anti-cutting layer is pasted and wrapped around the outside of the tire. The forming drum body 102 is activated, causing the tire and anti-cutting layer to rotate. Then, the controller 103 extends the servo electric cylinder 202, causing the lifting plate 203, guided by the light bar 204, to drive the ultrasonic pressure roller assembly to contact the outer wall of the anti-cutting layer. The disc spring 205 adapts accordingly. When the pressure sensor 206 detects that the pressure of the ultrasonic pressure roller assembly on the anti-cutting layer reaches the set value, the servo electric cylinder 202 maintains its length and the ultrasonic generator 306 is activated. The ultrasonic generator 306, in conjunction with the first cable 307, the second cable 308, and the electromagnetic slip ring 305, causes the ultrasonic transducer inside the hollow roller 302 to vibrate, thereby realizing the ultrasonic vibration of the hollow roller 302.

The machine 403 allows outside cold air to enter the hollow roller 302 through the telescopic hose 404 and rotary joint 402 to cool the ultrasonic transducer. Hot air inside the hollow roller 302 is discharged through multiple exhaust holes 405. Simultaneously, a dustproof net 406 prevents external dust from entering the hollow roller 302 and adhering to the surface of the ultrasonic transducer. Two sets of air supply valves 503 on the first set of air supply pipes 502 are opened, and two sets of air supply valves 503 on the second set of air supply pipes 502 are closed, thereby allowing the first set of... The filter screen inside the filter box 504 filters dust from the cold air delivered by the blower 403. After a period of use, when it is necessary to clean the filter screen inside the first filter box 504, the operator opens the two sets of air supply valves 503 on the second set of air supply pipes 502 and closes the two sets of air supply valves 503 on the first set of air supply pipes 502, thereby switching between the two sets of filter boxes 504. After the operator removes the sealing cover 505 on the first set of filter boxes 504, the corresponding filter screen is taken out and cleaned, so as to achieve non-stop operation.

[0027] The main functions achieved by this invention are: 1. High-frequency ultrasonic vibration is introduced into the roller, which actively intervenes in the interface between the anti-cut layer and the tire matrix during the pressing process. By utilizing the micro-friction effect, cavitation effect and local heat energy of ultrasonic waves, the inert layer on the surface of aramid is destroyed at the molecular level, and the flow and wetting of rubber are promoted. This achieves a fundamental transformation from "physical compaction" to "physical-chemical synergistic bonding". This method is specifically designed to solve the extremely difficult bonding scenario of "aramid anti-cut layer of aerospace tires" and is not a simple transfer of general welding technology. 2. The functions of the disc spring 205 are as follows: (1) Provide constant and compliant clamping force: ensure that the vibrating hollow roller and the curved tire always maintain stable contact, and the pressure does not fluctuate with microscopic fluctuations; (2) Isolation of harmful vibrations: As a "mechanical filter", it limits the high-frequency working vibration of the hollow roller to a local area, preventing it from being transmitted to the lifting seat and the whole machine, thus protecting the precision transmission components; (3) Bidirectional impact buffer: It protects the ultrasonic transducer from the reverse impact of the tire joint and also buffers the instantaneous force of the hollow roller on the tire. 3. The viscoelasticity and high damping properties of the uncured rubber of the tire matrix and the cord composite layer are utilized. During the pressing process, the tire material is not a rigid body, and its adaptive deformation actively absorbs and dissipates most of the transmitted vibration energy. The tire forms a natural "second" vibration attenuation barrier: combined with the active isolation of the disc spring, it constitutes double vibration isolation, making the residual vibration transmitted to the molding drum negligible. The vibration energy is "trapped" and consumed to the maximum extent in the interface area that needs to be treated, which not only improves the processing efficiency, but also protects the system.
