Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire testing, and in particular to a tire self-healing adhesive adhesion testing device. Background Technology
[0002] Tire self-sealing technology, as an effective solution for tire punctures, relies on a special self-sealing adhesive material pre-coated or injected into the tire's interior. This material automatically flows to fill the puncture when the tire is punctured, maintaining tire pressure and ensuring driving safety. However, the adhesion between the self-sealing adhesive and the tire's inner wall is a key indicator determining its long-term effectiveness and reliability. Insufficient adhesion can cause the adhesive layer to peel off and fail under tire rolling deformation or high-temperature conditions, resulting in the loss of its self-sealing function. Currently, methods for testing this adhesion have significant limitations: Traditional static peel tests (such as peeling rubber samples from small pieces of tire inner wall specimens) cannot realistically simulate the dynamic loads, complex stress states, and continuous rolling deformation conditions that tires experience during actual driving. The test results have a poor correlation with actual performance. On the other hand, equipment that attempts to conduct tests under dynamic conditions is often complex in structure, cumbersome in operation, and lacks safety. For example, it lacks an effective lateral restraint device for high-speed rotating tires, posing a significant safety hazard of tires accidentally detaching and injuring people during the test.
[0003] Therefore, a tire self-healing adhesive adhesion testing device is now being developed to address the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of existing devices during use, this utility model provides a tire self-healing adhesive adhesion testing device.
[0005] The technical solution of this utility model: A tire self-sealing adhesive adhesion testing device includes a mounting frame, a conveyor belt assembly mounted on the mounting frame, a drive motor mounted on the outer side of the mounting frame, the output shaft of the drive motor being connected to the conveyor belt assembly, the drive motor driving the conveyor belt assembly to rotate, sliding blocks slidably mounted on both the left and right sides of the middle of the mounting frame, mounting rollers rotatably mounted on each sliding block, a tire to be tested mounted between the two mounting rollers, a sliding plate slidably mounted on the top of the mounting frame, a pressure frame slidably mounted in the middle of the sliding plate, a testing component for testing tire adhesion mounted on the upper part of the sliding plate, and the bottom of the testing component being connected to the pressure frame.
[0006] Furthermore, it is particularly preferred that the mounting frame also includes a mounting plate, which is connected to the left and right sides of the mounting frame. A hydraulic cylinder is provided on the top of the mounting plate, and a contact plate is connected to the top of the telescopic end of the hydraulic cylinder.
[0007] Furthermore, it is particularly preferred that the mounting frame also includes baffles, which are rotatably connected to both the front and rear sides of the left side of the mounting frame, and fixed posts are fixedly connected to both the front and rear sides of the right side of the mounting frame.
[0008] Furthermore, it is particularly preferred that the bottom of the pressure frame contacts the sliding block.
[0009] Furthermore, it is particularly preferred that the contact plate be elongated to prevent the sliding block from falling off the side after it has been lifted off the mounting frame.
[0010] Furthermore, it is particularly preferred that each of the fixed columns is rotatably connected to a rotating locking device, which is used to lock the baffle.
[0011] By adopting the above technical solution, compared with the prior art, this utility model has the following advantages: This device significantly improves the automation, ease of operation, and accuracy of tire self-sealing adhesive adhesion testing. The testing components continuously collect force and displacement changes caused by the stress on the self-sealing adhesive interface when the tire rotates through a pressure frame, accurately reflecting the actual adhesion performance of the interface between the adhesive layer and the tire inner wall under dynamic load. The testing process is safe, efficient, and reliable, significantly improving testing efficiency and accuracy. Attached Figure Description

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0017] A device for testing the adhesion of tire self-sealing adhesive, such as Figures 1-3 As shown, the device includes an installation frame 1, a conveyor belt assembly 2 on the installation frame 1, a drive motor 3 on the outside of the installation frame 1, the output shaft of the drive motor 3 being connected to the conveyor belt assembly 2, the drive motor 3 being used to drive the conveyor belt assembly 2 to rotate, sliding blocks 4 being slidably installed on both the left and right sides of the middle of the installation frame 1, mounting rollers 5 being rotatably installed on each sliding block 4, the tire to be tested being installed between the two mounting rollers 5, a sliding plate 6 being slidably installed on the top of the installation frame 1, a pressure frame 7 being slidably installed in the middle of the sliding plate 6, the bottom of the pressure frame 7 being in contact with the sliding block 4, and a test assembly 8 for testing tire adhesion being installed on the upper part of the sliding plate 6. The bottom of the test component 8 is connected to the pressure frame 7. The left and right sides of the mounting frame 1 are connected to the mounting plates 9. The top of the mounting plate 9 is equipped with a hydraulic cylinder 10. The top of the extension end of the hydraulic cylinder 10 is connected to a contact plate 11. The contact plate 11 is long and narrow to prevent the sliding block 4 from falling off the side after being pushed off the mounting frame 1. The left front and rear sides of the mounting frame 1 are rotatably connected to baffles 12. The right front and rear sides of the mounting frame 1 are fixedly connected to fixed columns 13. Rotating clips 14 are rotatably connected to the fixed columns 13. The rotating clips 14 are used to lock the baffles 12.
[0018] The working principle of this tire self-sealing adhesive adhesion testing device focuses on evaluating the adhesion performance between the internal self-sealing adhesive and the tire inner wall bonding interface under simulated dynamic load and rolling conditions. When the device is started, the drive motor 3 mounted on the outside of the mounting frame 1 drives its output shaft, which in turn drives the conveyor belt assembly 2 on the mounting frame 1 to start running, providing basic motion power for the entire testing process. During the preparation stage, the operator slides the sliding plate 6 forward to provide space for the entire tire to be placed. Then, the sliding block 4 and the mounting roller 5 are taken out upwards. The tire to be tested, which has been injected with self-healing adhesive, is placed at the center of the left and right sides and the mounting roller 5 is installed. These two mounting rollers 5 are key clamping and driving components. Then, the tire with the mounting roller 5 and the sliding block 4 installed is placed inside the mounting frame 1. Finally, the sliding plate 6 is slid back to reset so that the pressure frame 7 is back above the sliding block 4 and in contact with the sliding block 4. The sliding block 4 can move up and down along the mounting frame 1. This sliding connection provides displacement freedom for subsequent simulation of tire load. After the tire position is adjusted, the test environment needs to be locked. At this time, the operator flips the baffle 12, which is rotatably connected on the front and rear sides of the left side of the mounting frame 1, inwards so that it stands upright and forms a physical barrier on the side of the tire. Subsequently, the rotating clips 14, which are fixedly connected to the fixed columns 13 on the front and rear sides of the right side of the mounting frame 1, are rotated one by one to reliably hook and press the edge of the baffle 12, thereby mechanically locking the baffle 12 to prevent the tire from being accidentally thrown out during the subsequent high-speed rolling test and to ensure operational safety. After the baffle 12 is locked, the tire enters the clamping and initial state, and the drive motor 3 drives the drive mounting roller 5 on the pulley assembly to start rotating; the tire, which is tightly clamped by the mounting rollers 5 on both sides, contacts the conveyor belt and rotates synchronously to simulate the rolling state of the tire during vehicle operation. When the tire reaches the preset stable speed, the core adhesion test is started: the pressure frame 7 is slidably installed in the middle of the sliding plate 6 at the top of the mounting frame 1, and the bottom of the pressure frame 7 contacts the top of the sliding blocks 4 that have been raised on both sides below; A test assembly 8 for precise tire adhesion testing is mounted on the upper part of the sliding plate 6. The bottom of the test assembly 8 is fixedly connected to the pressure frame 7. At the start of the test, the rotation of the tire causes the sliding block 4 to produce a small, controllable upward displacement. This force is ultimately transmitted to the test assembly 8 through the pressure frame 7. When the adhesion of the self-healing adhesive at a certain point on the rotating tire's inner wall is insufficient to resist external peeling forces, the adhesive layer at that point will peel off or detach. The test software analyzes recorded force and displacement curves, or the critical force value that triggers the peeling event, to determine the dynamic adhesion performance. After completing a certain test cycle, the drive motor 3 is stopped, thus stopping the overall testing operation of the device and releasing the locking of the rotating clamp 14 to the baffle 12. Flip the baffle 12 to flatten and reset it. Slide the sliding plate 6 on the top of the mounting frame 1 forward to disengage the pressure frame 7 from the sliding block 4, thus providing space for tire removal. Mounting plates 9 are connected to the left and right sides of the mounting frame 1. A hydraulic cylinder 10 is installed on the top of the mounting plate 9. Start the hydraulic cylinder 10 to lift its telescopic end upward. The lifting force is evenly transmitted to the sliding blocks 4 on both sides below through the long strip contact plate 11 connected to the top of the telescopic end. Under the upward force of the hydraulic cylinder 10, the sliding blocks 4 on the left and right sides slide and lift upward, thereby driving the mounting rollers 5 connected to them to move upward. Finally, the mounting rollers 5 on both sides together tightly clamp and lift the tire in the middle, thereby pushing out the sliding block 4, the mounting rollers 5 and the tire, making it easy to remove the whole tire.
