Description

Technical Field

[0001] This utility model relates to the field of impact testing technology for paint protection films, specifically an impact testing device for impact-resistant protective films. Background Technology

[0002] Paint Protection Film (PPF), also known as "invisible car wrap," is a high-performance film that covers the surface of a car's paint. It is mainly used to prevent damage to the paint surface from scratches, corrosion, ultraviolet rays, etc. After the paint protection film is produced, it needs to be subjected to impact testing to test the strength of the paint protection film in protecting the car's paint surface.

[0003] Most existing testing methods for paint protection films are single-test modes, usually testing the impact resistance of the film only through sandblasting or single-point impact tests. These single-test methods cannot fully reflect the real working conditions of paint protection films, which may be subjected to a combination of factors such as sand and gravel impacts and external force impacts in actual use, thus leading to a certain deviation between the test results and the actual use effect.

[0004] Therefore, it is necessary to design an impact testing device for impact-resistant protective films to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an impact testing device for impact-resistant protective films, which solves the technical problems mentioned in the background art.

The outer surfaces of the two screws are rotatably connected with a lifting plate, and the bottom of the two lifting plates are fixedly connected with two positioning pins. The bottom ends of the four lifting plates are slidably inserted into the bottom of the clamping plate, and the bottom ends of the four positioning pins are fixedly connected with a first limiting plate.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3This utility model provides an impact testing device for impact-resistant protective films, including a testing frame 1. A first servo motor 5 is fixedly connected to the top of the testing frame 1. The output shaft of the first servo motor 5 is fixedly connected to a first rotating shaft 6, and a second turntable 4 is fixedly connected to the bottom of the first rotating shaft 6. Two symmetrical connecting posts 3 are fixedly connected to the bottom of the second turntable 4, and a first turntable 2 is fixedly connected to the bottom ends of the two connecting posts 3. A sandblasting pipe 7 is fixedly inserted into the outer surface of the first turntable 2. Fixing plates 18 are fixedly connected to both sides of the inner cavity of the testing frame 1, and a fixing frame 17 is fixedly connected between the two fixing plates 18. Symmetrical... The system includes two support columns 29, with a region frame 16 fixedly connected between them. A support plate 11 is fixedly connected to the top of the region frame 16. A second servo motor 8 is fixedly connected to one side of the support plate 11. A second rotating shaft 9 is fixedly connected to the output shaft of the second servo motor 8. A third turntable 10 is fixedly connected to one end of the second rotating shaft 9. A rotating block 12 is rotatably connected to one side of the third turntable 10, and a reciprocating sliding column 13 is rotatably connected to the bottom end of the rotating block 12. A connecting piece 15 is fixedly connected to the top of the region frame 16. A positioning tube 14 is fixedly inserted into the inside of the connecting piece 15, and the reciprocating sliding column 13 is slidably inserted into the inside of the positioning tube 14. Furthermore, a connecting rope 20 is fixedly connected to the bottom end of the reciprocating sliding column 13, and an impact detection ball 21 is fixedly connected to the bottom end of the connecting rope 20. A servo electric cylinder 19 is fixedly connected to the bottom of the inner cavity of the detection frame 1, and a clamping plate 28 is fixedly connected to the top end of the servo electric cylinder 19. The clamping plate 28 is provided with a clamping mechanism for clamping the paint protection film. Through the clamping mechanism, the detected paint protection film can be clamped on the top of the clamping plate 28, and the clamping plate 28 is attached to the bottom of the fixed frame 17 by extending the area frame 16. Then, the sandblasting pipe 7 can be connected to the pipe of the sandblasting machine with a flexible hose. Furthermore, by opening the first servo motor 5 and the second servo motor 8, on the one hand... The first turntable 2 is rotated by two connecting columns 3, thereby using the circumferential rotation of the sandblasting pipe 7 to perform sandblasting inspection on the circumferential area inside the fixed frame 17 outside the area frame 16. The activation of the second servo motor 8 causes the reciprocating sliding column 13 to slide back and forth inside the positioning tube 14 through the rotation of the third turntable 10. This allows the impact detection ball 21 to perform impact testing on the paint protection film. Thus, through the structure of the above device, the paint protection film can be simultaneously tested for sand and gravel friction and external force impact, improving the impact testing efficiency of the paint protection film. Moreover, for the same film, the test data from both methods are relatively accurate and do not interfere with each other.

[0021] To facilitate the clamping and inspection of the paint protection film, the clamping mechanism includes two lifting plates 23. Screws 25 are threaded onto both sides of the clamping plate 28. A knob 22 and a second limiting piece 27 are fixedly connected to the top and bottom ends of each screw 25. A lifting plate 23 is rotatably connected to the outer surface of each screw 25. Two positioning posts 24 are fixedly connected to the bottom of each lifting plate 23. The bottom ends of all four lifting plates 23 are slidably inserted into the bottom of the clamping plate 28. A first limiting piece 26 is fixedly connected to the bottom end of each of the four positioning posts 24. By rotating the two knobs 22, the rotation of the two screws 25 and the downward movement of the two lifting plates 23 clamp both sides of the paint protection film for inspection.

[0022] To facilitate dividing the detection area into two parts for two detection methods, both the area frame 16 and the fixing frame 17 are square boxes with openings at the top and bottom, and the bottom of the clamping plate 28 is in contact with the bottom of both the fixing frame 17 and the area frame 16.

[0023] To more stably test the paint protection film, the impact testing ball 21 is slidably disposed inside the area frame 16, and the impact testing ball 21 is slidably disposed between the bottom of the connecting piece 15 and the top of the clamping plate 28.

[0024] To avoid the impact of sand and gravel impact detection on external force impact detection, the sandblasting pipe 7 is rotatably disposed on the outside of the area frame 16, and the sandblasting pipe 7 is rotatably disposed inside the fixed frame 17.

[0025] In order to prevent the hose from being blocked by external objects when the blasting pipe 7 rotates after the hose is connected, the two connecting posts 3 are respectively fixed to both sides of the blasting pipe 7, and the blasting pipe 7 is rotatably positioned between the two connecting posts 3, and the third turntable 10 is rotatably positioned below the bottom of the first turntable 2.

[0026] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments.
