[0044] When the first linear cylinder extends, the sampling inner ring 21 and the sampling blade 22 rise until they abut against the film material. At this time, the first linear cylinder continues to extend, and the first spring 314 and the second spring contract under pressure to play a role in flexibility regulation.

[0045] The second linear drive mechanism 6 is a second linear cylinder, which includes a second cylinder body and a second piston rod. The end of the second cylinder body away from the second piston rod is connected to the base 1, and the end of the second piston rod away from the second cylinder body is connected to the outer ring mounting plate 7.

The first linear drive mechanism 4 can continue to extend so that the outer ring mounting plate 7 and the sampling mechanism 2 have sufficient pressure, and the first flexible contact component 31 and the second flexible contact component 32 are contracted, specifically the first spring 314 and the second spring are contracted, which plays a role in self-regulation of pressure, and while ensuring sufficient pressure, it can also avoid excessive pressure from damaging the equipment; then the rotary drive mechanism 5 is started to drive the first linear drive mechanism 4 to rotate, thereby driving the sampling mechanism 2 to rotate, and the blade is rotated to cut the film material. Since the outer ring 71 is tightened to press the film material, the film material will not rotate with the sampling inner ring 21. The device has a high sampling success rate, good stability, and a high flatness of the film material after punching.
