The diaphragm after the test could no longer be used, resulting in a waste of resources. Secondly, the diaphragm needs to be kept flat before it can be used. If the diaphragm is easily deformed after being bent, the previous testing equipment did not test the diaphragm's anti-bending performance. Summary of the invention

At this time, the hydraulic press drives the loading platform and the buffer tile on its top to engage with the pressure roller, and the diaphragm is locked between the pressure roller and the buffer tile. During the process of the torsion motor driving the pressure roller to rotate, the torque detector will calculate the tension of the diaphragm, and the strong rubber band on the outer side of the buffer tile prevents the torsion motor from applying too strong pressure to break the diaphragm, thereby solving the problems mentioned in the background technology.

If there are uneven parts on the diaphragm, the crossbar and the rocking arm on its side wall will twist, and the tip of the rocking arm will touch the sensing grating, thereby detecting whether the diaphragm can return to a flat state after bending and stretching.

The diaphragm 701 stops after being pulled for a certain distance. The hydraulic press 202 drives the stage 201 and the buffer tile 3 on its top to close on the pressure rod 102. The diaphragm 701 is locked between the pressure rod 102 and the buffer tile 3. During the process of the torsion motor 104 driving the pressure rod 102 to rotate, the torque detector 104 will calculate the tension of the diaphragm 701.

[0029] The flexure mechanism includes a twisting frame 5 below the top plate 4, which is fixedly connected to the bottom surface of the top plate 4 through a cantilever bridge 501. Three twisting bars 502 are arranged on the inner wall of the twisting frame 5. The diaphragm 701 passes through the gaps between the twisting bars 502. The diaphragm 701 passes through the middle of the three twisting bars 502 before the tensile test. At this time, the diaphragm 701 will be twisted, and the staff can observe the twisting and rebound performance of the diaphragm 701 with the naked eye.

[0030] The twisting bar 502 is fixedly connected to the side wall of the twisting frame 5 by countersunk bolts, and the staff can replace the twisting bars 502 of different sizes according to the detection requirements.

The diaphragm 701 after the stretching detection is completed immediately reaches the working station of the forked rod 803, and the steel ball at the end of the forked rod 803 abuts against the diaphragm. If there is an uneven part on the diaphragm 701, the cross bar 801 and the rocking rod 804 on its side wall will twist, and the tip of the rocking rod 804 will touch the sensing grating 8, thereby detecting whether the diaphragm 701 can return to a flat state after bending and stretching.

[0032] The outer side of the cross bar 801 is provided with a torsion spring 802, one end of the torsion spring 802 is fixedly connected to the outer side wall of the cross bar 801, and the other end of the torsion spring 802 is fixedly connected to the side wall of the detection plate 6.

The swing arm 804 can be replaced with different lengths. The longer the length of the swing arm 804 is, the higher the detection accuracy of the swing arm 804 is.

[0034] Working principle: the diaphragm 701 is pulled out from the outside of the discharge roller 704 and then passed over the pressure roller 102 and connected to the winding roller 703. The diaphragm 701 stops after being pulled for a certain distance. The hydraulic press 202 drives the stage 201 and the buffer tile 3 on its top to close on the pressure roller 102, and the diaphragm 701 is locked between the pressure roller 102 and the buffer tile 3. During the process of the torsion motor 104 driving the pressure roller 102 to rotate, the torque detector 104 will calculate the tension of the diaphragm 701. The strong rubber band 303 on the outside of the buffer tile 3 prevents the torsion motor 104 from applying too strong pressure to break the diaphragm 701. After the diaphragm 701 stops after being pulled for a certain distance, the clutch cylinder 706 drives the pin rod 707 to extend out to lock the extension shaft 705 and the discharge roller 704. The diaphragm 701 is pulled out from the middle of the three twisted bars 502 before the tensile test. When it is passed over, the diaphragm 701 will be twisted, and the staff can observe the twisting and rebound performance of the diaphragm 701 with the naked eye. The staff will replace the twisting bars 502 of different sizes according to the detection requirements. The diaphragm 701 that has completed the stretching detection will then reach the work station of the forked rod 803, and the steel ball at the end of the forked rod 803 will hit the diaphragm. If there are uneven parts on the diaphragm 701, the cross bar 801 and the rocking bar 804 on its side wall will twist, and the tip of the rocking bar 804 will touch the sensing grating 8, and then it can be detected whether the diaphragm 701 can return to a flat state after twisting and stretching. The torsion spring 802 can balance the gravity of the forked rod 803 and the steel ball, thereby increasing the detection accuracy. The rocking bar 804 can be replaced with different lengths. The longer the length of the rocking bar 804 is, the higher the detection accuracy of the rocking bar 804 is.
