A second clamping plate 321 corresponding to the first clamping plate 223 is provided on the second mounting plate 32. By rotating the second transverse lead screw, the second transverse moving seat 31 moves along the second transverse guide rail 3. The first clamping plate 223 and the second clamping plate 321 cooperate with each other, activating the drive cylinder 222. The piston rod of the drive cylinder 222 extends, and the first clamping plate 223 and the second clamping plate 321 apply resistance to the filter media, simulating the test of the filter media performance under resistance conditions.
[0028] Reference Figure 1 A drive motor 24 is mounted on the first transverse guide rail 2. A bevel gear pair is provided between the output shaft of the drive motor 24 and the first transverse lead screw. A connecting shaft 33 is rotatably connected inside the second transverse guide rail 3. The connecting shaft 33 is connected to the second transverse lead screw through the bevel gear pair. Connecting wheels 331 are coaxially fixedly connected to both the output shaft of the drive motor 24 and the connecting shaft 33. The two connecting wheels 331 are connected by a connecting belt 332. When the drive motor 24 is started, it drives the first transverse lead screw to rotate. At the same time, the output shaft of the drive motor 24 and the connecting shaft 33 rotate synchronously through the connecting wheels 331 and the connecting belt 332, thereby causing the first transverse lead screw and the second transverse lead screw to rotate synchronously, and thus causing the first mounting plate 22 and the second mounting plate 32 to move synchronously.
[0029] Reference Figure 1The support frame 1 is provided with a longitudinal moving component 4 for synchronously moving the first transverse guide rail 2 and the second transverse guide rail 3 along the filter material conveying direction. The longitudinal moving component 4 includes a longitudinal moving guide rail 41 and a longitudinal guide rail 42.

The longitudinal moving seat 43 is installed on the longitudinal moving guide rail 41 and is threadedly connected to the longitudinal lead screw. The longitudinal guide seat 44 is installed on the longitudinal guide rail 42 and is slidably connected to the longitudinal guide rail 42. Start the working motor to drive the longitudinal lead screw to rotate, which in turn drives the longitudinal moving seat 43 to move along the longitudinal moving guide rail 41, thereby moving the first transverse guide rail 2 and the second transverse guide rail 3. During the movement of the first transverse guide rail 2 and the second transverse guide rail 3, the longitudinal guide seat 44 moves along the longitudinal guide rail 42 to improve stability.

The second transverse guide rail 3 is located between the two synchronous rollers 5. The two ends of the two synchronous rollers 5 are rotatably connected to the longitudinal moving seat 43 and the longitudinal guide seat 44. During the movement of the longitudinal moving seat 43 and the longitudinal guide seat 44, the two synchronous rollers 5 are driven to move, thereby facilitating the adjustment of the tension of the filter material.
[0031] Reference Figure 1 and Figure 2 The support frame 1 is rotatably connected to two ends along the filter media conveying direction, with a power roller 6 and a support roller 7 located below the longitudinal moving guide rail 41. The power roller 6 provides power for the movement of the filter media by rotating the power roller 6, and the support roller 7 supports the filter media to prevent it from sagging.
[0032] The implementation principle of an air filter material tester according to an embodiment of this application is as follows: Power is provided for the movement of the filter material by rotating the power roller 6. The filter material is conveyed by the fixed roller 11, causing the first transverse screw to rotate. The first transverse moving seat 21 moves along the first transverse guide rail 2, and the first mounting plate 22 moves above the filter material. The drive motor 24 is started, driving the first transverse screw to rotate. Simultaneously, the output shaft of the drive motor 24 and the connecting shaft 33 rotate synchronously through the connecting wheel 331 and the connecting belt 332, thereby causing the first transverse screw and the second transverse screw to rotate synchronously, thus causing the first mounting plate 22 and the second mounting plate 32 to move synchronously. The drive cylinder 222 is started, and the piston rod of the drive cylinder 222 extends. The first clamping plate 223 and the second clamping plate 321 apply resistance to the filter material, simulating the performance test of the filter material under resistance conditions. The test element 221 performs the test on the filter material performance.
