Description

Technical Field

[0001] This utility model relates to the field of paint protection film repair and testing technology, specifically a repair capability testing machine for paint protection film. Background Technology

[0002] A paint protection film (PPF) self-healing capability testing machine is a device used to demonstrate and test the self-healing function of PPF. The machine uses tools such as steel brushes to create scratches on the surface of the PPF. By heating or under specific conditions, the self-healing function is triggered, visually demonstrating the process of the scratches disappearing. This tests the repair speed and effect of the PPF under different conditions to verify the reliability of its self-healing performance. While most PPF tests are conducted manually by scratching the film, this method is very time-consuming and labor-intensive, reducing testing efficiency and practicality.

[0003] To overcome the above-mentioned defects, in the prior art 1 (Chinese patent application number CN202220844942.8, application date 2022-04-13), a device for testing the repair capability of paint protection film uses a scraper connected to a spring mounted on the surface of a pressure sensor. A cylinder at the top controls the scraper at the bottom to scrape the surface of the paint protection film. The pressure sensor and spring control the scraping stress of the scraper at the end face, thereby achieving scraping effects under different stresses. Although the prior art can save manual labor, the excessive pressure of the blade holder during the scratching process can lead to insufficient tension of the paint protection film, which will affect the subsequent scratch testing of the paint protection film and reduce the repair testing efficiency. Therefore, the device for testing the repair capability of paint protection film is proposed, which can effectively solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a repair capability testing machine for paint protection film, in order to solve the problem mentioned in the background art that the paint protection film on the market is not tensioned enough during the scratching process due to excessive extrusion pressure from the cutter head, which affects the subsequent scratch testing of the paint protection film, reduces the repair testing efficiency, and has poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a repair capability testing machine for paint protection film, comprising a testing table and a clamping seat disposed on the upper surface of the testing table for clamping the paint protection film. The internal rotation of the testing table is achieved by a drive motor to rotatably mount a threaded rod, and the threaded rod is threadedly connected to a movable frame. The movable frame is slidably mounted on the upper surface of the testing table. An adjusting rod is disposed above the movable frame, and a tool holder is connected to the bottom end of the adjusting rod. The tool holder corresponds to the clamped paint protection film. A rectangular top plate is disposed on the upper surface of the testing table, and two extrusion rods are rotatably connected to the bottom of the top plate. A movable block is rotatably connected to the bottom end of the two extrusion rods. The upper surface of the top plate corresponds to the paint protection film.

[0006] Preferably, the two movable blocks are slidably mounted inside the detection table, and the two movable blocks are symmetrically arranged about the vertical center line of the detection table.

[0007] Preferably, the two extrusion rods are inclined and have the same structure.

[0008] Preferably, a bidirectional lead screw is rotatably mounted inside the testing platform, and moving blocks are threaded through both sides of the bidirectional lead screw, and a throttle handle is connected to the right end of the bidirectional lead screw.

[0009] Preferably, two baking lamps are rotatably mounted on the top of the mobile frame, and the two baking lamps are connected to a driving power supply via a wiring harness, and the driving power supply is located inside the mobile frame.

[0010] Preferably, the two baking lamps are provided with a second magnet on the side near the movable frame, and the outer surfaces of the two second magnets correspond to the first magnets, wherein the two first magnets are symmetrically arranged on the inner sides of the two mounting plates.

[0011] Preferably, the first magnet and the second magnet have the same magnetic poles.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Equipped with a top plate, which is installed on the upper surface of the testing table, when the tension of the car cover needs to be adjusted, only two moving blocks need to be moved to retract. At this time, the two retracting moving blocks will drive the two extrusion rods to simultaneously squeeze the top plate and move it upward. This allows the rising top plate to adjust the tension of the car cover after it is positioned and clamped, so as to achieve better repair and testing of the car cover and improve its practicality.

[0013] Furthermore, when it is necessary to adjust the tension of the car cover after it is positioned and clamped, simply turn the throttle to drive the bidirectional lead screw to rotate. At this time, the rotating bidirectional lead screw will simultaneously drive the two moving blocks to move in position, thereby adjusting the tension of the car cover. The operation is more time-saving and labor-saving.

[0014] Equipped with a threaded rod, which is slidably mounted inside the testing table, and with a movable frame threaded through the outside of the threaded rod, different levels of scratch detection on the car cover can be performed simply by rotating the threaded rod to move the movable frame. The movable frame will then move the tool holder to perform scratch detection on the clamped and positioned car cover, thus improving the practicality of manual operation.

[0015] Furthermore, when it is necessary to adjust the degree of scratching on the tool holder, the height of the tool holder can be adjusted by adjusting the adjusting rod, thereby adjusting the scratching angle of the tool holder to achieve scratch detection at different levels and improve the subsequent detection effect.

[0016] Equipped with a first magnet and a second magnet, after the car cover is scratched, two baking lamps are activated to heat the scratched car cover. Heating the car cover causes the TPU molecular chains to move, gradually eliminating the scratches and restoring the surface of the car cover to its original state. Conversely, if the scratches do not disappear, it indicates a failure in the test. As the moving frame moves the two baking lamps, the two baking lamps drive the two second magnets and the two first magnets to swing their positions based on the principle of like poles repelling each other in the magnetic field. This expands the baking range of the two baking lamps and improves the accuracy of the car cover test. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides the following technical solution: a repair capability testing machine for paint protection film. Example 1: To address the problem that existing car covers suffer from insufficient tension during scratch testing due to excessive pressure from the blade holder 5, which affects subsequent scratch detection and reduces repair efficiency and practicality, the following invention is disclosed: a testing platform 1 and a clamping seat 2 on the upper surface of the testing platform 1 for holding the car cover. The testing platform 1 has a threaded rod 4 mounted internally via a drive motor, and the threaded rod 4 is threadedly connected to a movable frame 3, which is slidably mounted on the upper surface of the testing platform 1. An adjusting rod 6 is positioned above the movable frame 3, and the bottom end of the adjusting rod 6 is connected to the blade holder 5, which corresponds to the clamped car cover. The upper surface of the testing platform 1 has a rectangular top plate 7, and two pressing rods 12 are rotatably connected to the bottom of the top plate 7. The bottom ends of the two pressing rods 12 are rotatably connected to a moving block 13, and the upper surface of the top plate 7 corresponds to the car cover.

[0021] The two movable blocks 13 are slidably installed inside the detection table 1, and the two movable blocks 13 are symmetrically arranged about the vertical center line of the detection table 1. The two extrusion rods 12 are inclined and have the same structure.

[0022] like Figures 1-6 As shown, when it is necessary to test the repairability of the car cover, simply position and clamp the car cover on the upper surface of the test table 1 through the four clamping seats 2, and then rotate the throttle 15 to drive the moving blocks 13 connected by threads on both sides of the two-way lead screw 14 to retract and move, so that the two moving blocks 13 drive the two extrusion rods 12 to drive the top plate 7 to move upward. At this time, the upward moving top plate 7 will adjust the tension of the car cover after positioning and clamping, so as to achieve better repair testing of the car cover and better practicality.

[0023] Example 2, unlike Example 1, utilizes two baking lamps 10 to expand the baking range of the car cover, thereby triggering its self-healing function and improving the detection efficiency. The following is disclosed: A bidirectional lead screw 14 is rotatably mounted inside the testing platform 1, and moving blocks 13 are threaded through both sides of the bidirectional lead screw 14. A throttle 15 is connected to the right end of the bidirectional lead screw 14. Two baking lamps 10 are rotatably mounted on the top of the moving frame 3, and the two baking lamps 10 are connected to a driving power supply through a wiring harness. The driving power supply is located inside the moving frame 3. A second magnet 11 is provided on the side of the two baking lamps 10 near the moving frame 3, and a first magnet 9 is corresponding to the outer surface of the two second magnets 11. The two first magnets 9 are symmetrically arranged on the inner side of the two mounting plates 8, and the first magnets 9 and the second magnets 11 have the same magnetic poles.

[0024] like Figures 1-4 As shown, rotating the threaded rod 4 will move the movable frame 3 to the upper surface of the inspection table 1. At this time, the movable frame 3 will drive the tool holder 5 to perform scratch operation on the car cover after it is clamped and positioned. When it is necessary to adjust the degree of scratch on the car cover, simply rotate the threaded rod 4 to move the movable frame 3 to the upper surface of the inspection table 1. At this time, the movable frame 3 will drive the tool holder 5 to perform scratch detection on the car cover after it is clamped and positioned, so as to improve the practicality of manual operation.

[0025] After the car cover is scratched, the two baking lamps 10 are activated to bake and heat the scratched car cover. At this time, the moving frame 3 will drive the two baking lamps 10 to dry and heat the scratched car cover. By heating the car cover, the TPU molecular chain segments move, the scratches gradually disappear, and the surface of the car cover is restored to its original state. Conversely, if the scratches do not disappear, it means that the test has failed. While the moving frame 3 moves the two baking lamps 10, the two baking lamps 10 will drive the two second magnets 11 and the two first magnets 9 to swing their positions through the principle of like poles repulsion in the magnetic field. This can expand the baking range of the two baking lamps 10 and improve the accuracy of the car cover test.
