Description

Technical Field

[0001] The present invention relates to the technical field of composite film detection, and in particular to a high-efficiency heat-insulating, flame-retardant, reflective composite film detection device and method. Background Art

[0002] After the flame retardant material is produced, it is necessary to conduct random inspections on the finished products. During the random inspection process, there is a necessary test process, which is to test the heat and fire resistance of the flame retardant material, and obtain reliable test parameters of the flame retardant material itself to ensure its stability and performance requirements after it is put on the market.

[0003] In the prior art, a Chinese patent with publication number "CN217133077U" discloses a test device for efficiently detecting flame retardant materials. The flame retardant material to be tested is clamped on a clamping plate, and the position of the clamping plate in the test chamber is fixed. The position of the flame retardant material to be tested can be adjusted by adjusting the position of the clamped material in the clamping plate. The adjustment and fixation are convenient. After the flame retardant material is placed in the test chamber, the flame retardant material is ignited by moving a horizontal rod for testing. This solves the problem that the existing device cannot effectively adjust and fix the distance between the flame retardant material and the fire source during the test.

[0004] As described above, the flame-retardant material is fixed by a fixed clamp. However, in this solution, since the clamp is fixed and the fire source can only move horizontally, the fire source can only burn the designated location of the flame-retardant material. This can cause some areas to burn excessively, while other areas may not be affected by the flame at all. As a result, the test results will be inaccurate and cannot truly reflect the flame-retardant effect of the material under different flame conditions. In addition, some existing testing devices cannot flatten the flame-retardant material to be tested, resulting in a wrinkled flame-retardant material after clamping. This can also lead to inaccurate test data. Summary of the Invention

[0018] S1. Pass one end of the composite film to be tested between the upper pressing roller and the lower pressing roller, and adjust the position of the adjusting block by rotating the adjusting screw and utilizing the cooperation between the adjusting screw and the first bearing and the limited sliding between the limiting slide and the first leveling frame. The position of the upper pressing roller is adjusted by utilizing the first mounting shaft on the adjusting block. The adjustable upper pressing roller and the lower pressing roller cooperate to facilitate fixing composite films of different thicknesses.

[0019] S2, the lifting plate is then driven to rise by the electric push rod, and the first connecting frame and the second connecting frame on the lifting plate are used to drive the first driving rod and the second driving rod to rise, and then the first driving rod cooperates with the third connecting frame, and the second driving rod cooperates with the fourth connecting frame, so that the first leveling frame and the second leveling frame are limited by the two limiting slides and move outward at the same time, and the upper pressing roller and the lower pressing roller are used to fit the composite film, so as to facilitate leveling the surface of the composite film;

The position of the upper pressure roller is adjusted by utilizing the first mounting shaft on the adjustment block, and the cooperation between the adjustable upper and lower pressure rollers facilitates the fixation of composite films of different thicknesses.

[0024] 2. The present invention drives the lifting plate to rise by an electric push rod, and utilizes the first connecting frame and the second connecting frame on the lifting plate to drive the first driving rod and the second driving rod to rise, and then through the cooperation of the first driving rod and the third connecting frame, and the cooperation of the second driving rod and the fourth connecting frame, the first leveling frame and the second leveling frame are moved outward at the same time through the limit of the two limit slides, and the upper and lower pressure rollers are used to fit the composite film to facilitate the leveling of the surface of the composite film;

[0025] 3. In the present invention, when the first and second leveling frames move outward, the second bearings on the first and second leveling frames will move synchronously, the auxiliary gear on the second mounting shaft will mesh with the gear plate, and the lower pressure roller will rotate through the drive of the second mounting shaft. The rotational force generated by the second mounting shaft facilitates applying an outward pushing force to the composite film, ensuring a better effect when leveling the composite film.

[0026] 4. In the present invention, after the composite film is flattened and fixed, the flamethrower is started, and the drive motor is started at the same time. The drive motor is used to drive the connecting inclined plate on the drive disk to rotate, and the driving rod on the connecting inclined plate will rotate with the drive disk as the center.

10. A method for detecting a high-efficiency heat-insulating flame-retardant reflective composite film, based on a device for detecting a high-efficiency heat-insulating flame-retardant reflective composite film according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Pass one end of the composite film to be tested between the upper pressure roller (8) and the lower pressure roller (9), and adjust the position of the adjustment block (33) by rotating the adjustment screw (35), utilizing the cooperation between the adjustment screw (35) and the first bearing (34), and the limited sliding of the limit slide (32) and the first leveling frame (6). The first mounting shaft (36) on the adjustment block (33) is used to facilitate the adjustment of the position of the upper pressure roller (8). The adjustable upper pressure roller (8) and the lower pressure roller (9) are used to facilitate the fixing of composite films of different thicknesses. S2, the lifting plate (23) is then driven to rise by the electric push rod (22), and the first connecting frame (24) and the second connecting frame (25) on the lifting plate (23) are used to drive the first driving rod (26) and the second driving rod (27) to rise, and then the first driving rod (26) cooperates with the third connecting frame (30), and the second driving rod (27) cooperates with the fourth connecting frame (31), so that the first leveling frame (6) and the second leveling frame (7) pass through the two limiting chute (29) and move outward at the same time, and the upper pressure roller (8) and the lower pressure roller (9) are used to fit with the composite film, so as to facilitate the leveling of the surface of the composite film; S3. When the first leveling frame (6) and the second leveling frame (7) move outward, the second bearings (37) on the first leveling frame (6) and the second leveling frame (7) will move synchronously, the auxiliary gear (39) on the second mounting shaft (38) will mesh with the tooth plate (40), and the lower pressure roller (9) will rotate through the drive of the second mounting shaft (38). The rotational force generated by the second mounting shaft (38) is used to facilitate the application of a force pushing the composite film outward, thereby ensuring a better effect when the composite film is leveled; S4. After the composite film is flat and fixed, the flamethrower (2) is started, and the driving motor (10) is started at the same time. The driving motor (10) is used to drive the connecting inclined plate (12) on the driving disk (11) to rotate. The driving rod (13) on the connecting inclined plate (12) will rotate with the driving disk (11) as the center. The circular block (14) and the driving column (16) on the driving rod (13) will rotate synchronously. The driving column (16) drives the detection frame (5) to swing and rotate through the cooperation of the mounting ring (19) and the arc connecting rod (20) and the cooperation of the connecting ring (21) and the positioning shaft (17). By swinging and rotating the composite film on the detection frame (5), the surface of the composite film can be evenly contacted with the flame generated by the flamethrower (2), effectively improving the detection accuracy of the composite film.
