[0001] This utility model relates to the field of vehicle color change film testing, and in particular to a vehicle color change film performance testing device. Background Technology

[0002] With the increasing demand for personalized car customization, car color change film, as a product that can quickly change the color of a car's exterior, has been widely used in the automotive aftermarket. Color change film not only meets consumers' pursuit of diverse vehicle appearances, but also has functions such as protecting the original paint and preventing minor scratches. The performance of color change film is directly related to its performance and lifespan.

[0003] Existing vehicle color change film testing methods typically involve extruding the film during the rolling process using extrusion equipment to test its extensibility and flexibility. However, current equipment can only test one performance metric and cannot combine multiple tests, making it difficult to comprehensively evaluate the performance and quality control of the color change film. This also hinders continuous testing and production, impacting production efficiency.

[0004] Therefore, it is necessary to design a vehicle color change film performance testing device that can detect the anti-aging performance, extensibility, flexibility and surface defects of the color change film while it is being wound up, so as to combine multiple tests, facilitate comprehensive evaluation of the color change film performance, facilitate continuous testing and production, and improve production efficiency. Utility Model Content

This device combines multiple tests, facilitates comprehensive evaluation of color-changing film performance, enables continuous testing and production, and improves production efficiency.

[0006] Technical Solution: A vehicle color change film performance testing device includes a base, a film feeding shaft, a connecting frame, a support frame, a connecting frame, a take-up shaft, a first motor, a connector, a pin, and a testing component.

The take-up shaft is rotatably and detachably connected to the upper right side of the base. The first motor is connected to the upper right rear side of the base. A connector is connected to the output shaft of the first motor. The connector passes through the base and engages with the take-up shaft. A pin is engaged on the right side of the connector and engages with the take-up shaft. A testing component for performing various tests on the vehicle color change film is provided between the connecting frame, the support frame, and the connecting frame.

[0007] Furthermore, the film-releasing shaft is I-shaped.

[0008] Furthermore, handles are provided on the upper sides of both the front and rear ends of the film feeding shaft and the winding shaft.

[0009] Furthermore, the detection assembly includes a xenon lamp, a laser detector, a lead screw, a slider, a roller, a second motor, a transmission assembly, a cylinder, and an extrusion frame. Multiple xenon lamps are connected to the upper part of the connecting frame. Laser detectors are connected to both the upper and lower parts of the connecting frame.

[0011] Furthermore, it also includes limit frames, with limit frames connected to the inner sides of both the front and rear parts of the connecting frame.

[0012] The beneficial effects are as follows: 1. This utility model winds up the color-changing film by rotating the winding shaft, and at the same time, it detects the anti-aging performance, extensibility, flexibility and surface defects of the color-changing film by illuminating the xenon lamp, pressing the extrusion frame and using a laser detector. This allows for the detection of the anti-aging performance, extensibility, flexibility and surface defects of the color-changing film while winding it up, realizing the combination of multiple detection methods. This facilitates a comprehensive evaluation of the color-changing film's performance, facilitates continuous testing and production, and improves production efficiency.

[0013] 2. This utility model uses the forward and reverse rotation of the lead screw to cause the front slider to move back and forth under the action of the thread, which causes the roller to move back and forth and rotate to smooth the color-changing film. The rear slider moves back and forth, thereby smoothing the color-changing film during the winding process, preventing wrinkles, bubbles and deformation, and improving the quality and adhesion effect of the color-changing film.

The film-laying shaft 2 is rotatably and detachably connected to the left side of the base 1. The film-laying shaft 2 is I-shaped to facilitate limiting the vehicle color-changing film. The connecting frame 3 is connected to the upper left side of the base 1, the support frame 4 is connected to the upper right side of the base 1, the connecting frame 5 is connected to the right side of the base 1, and the take-up shaft 6 is rotatably and detachably connected to the upper right side of the base 1. Both the film-laying shaft 2 and the take-up shaft 6 have [missing information - likely related to safety features]. The device has a handle for easy gripping and removal of the film-laying shaft 2 and the take-up shaft 6. The first motor 7 is connected to the upper right rear part of the base 1. The limiting frame 8 is connected to the inner sides of both the front and rear parts of the connecting frame 3 to facilitate the positioning of the vehicle color-changing film. The connecting member 16 is connected to the output shaft of the first motor 7. The connecting member 16 passes through the base 1 and engages with the take-up shaft 6. The right side of the connecting member 16 is engaged with the pin 17, which engages with the take-up shaft 6. A detection component for performing various tests on the vehicle color-changing film is provided between the connecting frame 3, the support frame 4, and the connecting frame 5.

[0023] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the detection assembly includes a xenon lamp 30, a laser detector 50, a lead screw 9, a slider 10, a roller 11, a second motor 12, a transmission assembly 13, a cylinder 14, and a pressing frame 15. Four xenon lamps 30 are connected to the upper part of the connecting frame 3. The laser detector 50 is connected to both the upper and lower parts of the connecting frame 5. Two lead screws 9 are rotatably connected to the inner front of the connecting frame 3. Slider 10s are threaded onto each lead screw 9, and the front sliders 10s are in contact with the connecting frame 3. Two sliders 10s are also slidably connected to the rear of the connecting frame 3. The two sliders 10 at the same height position are rotatably connected to the rollers 11. The front right part of the connecting frame 3 is connected to the second motor 12. The transmission assembly 13 is provided between the lead screw 9 and the output shaft of the second motor 12. The transmission assembly 13 includes pulleys and a flat belt. The right side of the lead screw 9 is connected to pulleys. The output shaft of the second motor 12 is also connected to pulleys. A flat belt is wound between the pulleys. The cylinder 14 is connected to the inner side of the upper part of the support frame 4. The telescopic end of the cylinder 14 passes through the support frame 4 and is connected to the extrusion frame 15.

[0024] When performance testing of vehicle color-changing film is required, this device can be used. The base 1 is brought into contact with the ground. The film-laying shaft 2, with the film wrapped around it, is then lifted by the handle and installed on the base 1. The film-laying shaft 2 is I-shaped to facilitate the positioning of the film. The winding shaft 6 is then lifted and installed on the base 1, engaging with the connecting member 16. The pin 17 is then inserted into the winding shaft 6 and the connecting member 16 for fixation. Next, the color-changing film is moved by hand, allowing it to pass through the limiting frame 8, between the rollers 11, through the support frame 4, and through the connecting frame 5. The film is then wound around the winding shaft 6. Finally, the first electric... Machine 7, driven by the first motor 7, rotates the connecting member 16, causing the winding shaft 6 to rotate and wind up the color-changing film, and the unwinding shaft 2 to rotate and unwind the film. Simultaneously, the second motor 12 is activated, driving the corresponding pulley to rotate, causing the flat belt to rotate, which in turn rotates the remaining pulleys, causing the lead screw 9 to rotate. Under the action of the thread, the front slider 10 moves, causing the roller 11 to move and rotate to smooth the color-changing film. The rear slider 10 moves until it reaches the rightmost side of the lead screw 9. Then, the second motor 12 reverses its operation, causing the corresponding pulley to rotate in the opposite direction, the flat belt to rotate in the opposite direction, the remaining pulleys to rotate in the opposite direction, and the lead screw 9 to rotate in the opposite direction. Under the action of the screw thread, the front slider 10 moves in the opposite direction to reset, causing the roller 11 to move in the opposite direction and rotate to smooth the color-changing film. The rear slider 10 also moves in the opposite direction, thus smoothing the color-changing film during the winding process, preventing wrinkles, bubbles, and deformation, and improving the quality and adhesion of the color-changing film. While smoothing, the xenon lamp 30 is activated to simulate real-life photo-oxidation, hydrolysis, and thermal oxidation reactions to test the anti-aging performance of the color-changing film. The smoothed color-changing film continues to move to below the extrusion frame 15, and then the cylinder 14 on the support frame 4 is activated. The cylinder 14 drives the extrusion frame 15 to move and extrude the color-changing film for extrusion testing. This extrusion process... The deformation during the process is used to determine the extensibility and flexibility of the color-changing film. The film is then moved further, and the laser detector 50 is used to inspect the surface for cracks, flatness, and defects. This allows for multiple inspections while the film is being wound up. The above operation is repeated to inspect and wind up the entire roll of film. If any defects are detected, the first motor 7 is turned off after the entire roll of film is wound up. Then, the pin 17 is removed, and the winding shaft 6 is removed using the handle for recycling. If the film passes inspection, the winding shaft 6 is removed for storage and reuse. This allows for the simultaneous inspection of the color-changing film's anti-aging properties, extensibility, flexibility, and surface defects during winding, enabling a comprehensive evaluation of the film's performance through a combination of multiple inspections.This facilitates continuous testing and production, improving production efficiency. After use, simply turn off the xenon lamp 30, the laser detector 50, the first motor 7, the second motor 12, and the cylinder 14.
