[0024] To achieve the up and down reciprocation of the experimental puncture needle 202, Figure 4 and Figure 5As shown in the figure, the sliding member includes a sliding seat 508 disposed above the workbench 1 and a connecting shaft 503 fixed to the front surface of the sliding seat 508. The right end of the connecting rod 502 far from the swing crank 501 is hinged to the end of the connecting shaft 503. An adjustment chute 5081 for cooperating with the roller 5092 is provided inside the sliding seat 508, and the outer surface of the roller 5092 is in rolling connection with the inner side of the adjustment chute 5081. Through the precise cooperation of components such as the swing crank 501, the connecting rod 502, the sliding seat 508, and the roller 5092, the precise up-and-down reciprocating movement of the experimental puncture needle 202 is achieved. This design ensures the consistency of the force and speed during the puncture process, thereby improving the accuracy and repeatability of the experiment.

The second buffer spring 512 surrounds the outside of the guide rod 511. The guiding member includes the limiting seats 504, the guide rod 505, the sliding sleeve 506, and the first buffer spring 507.

In addition, the second buffer spring 512 can be disassembled according to requirements for better puncture experiments.

[0026] As Figure 3 , Figure 6 and Figure 7 shown, in this embodiment, an annular groove 306 communicating with the outside is provided inside the placement seat 301, and a connecting frame 305 having a cross-shaped appearance and used for connecting with the intermittent structure 6 is bolted to the outer surface of the placement seat 301. There are two connecting frames 305, and the two connecting frames 305 are respectively located on the left and right sides of the annular groove 306. As Figure 7As shown in the figure, the intermittent structure 6 includes two connecting shafts 601, a groove disk 602 and a grooved pulley 603 fixed on the two connecting shafts 601. The groove disk 602 and the grooved pulley 603 are intermittently engaged. Among them, the connecting shaft 601 connected to the groove disk 602 is fixed to the outer surface of the connecting frame 305. And a swing arm 604 is fixed on the connecting shaft 601 connected to the grooved pulley 603. A dial rod 605 is installed at the other end of the swing arm 604. A number of equidistant and open radial grooves 606 are formed inside the groove disk 602. The dial rod 605 is intermittently engaged with the radial grooves 606. Through the intermittent engagement between the radial grooves 606 on the groove disk 602 and the dial rod 605, the intermittent rotation of the object placing seat 301 is realized. This design not only simplifies the transmission mechanism, but also improves the accuracy and stability of rotation, ensuring the one-by-one and orderly testing of the thin film during the experiment.

[0027] It should be noted that the two synchronous shafts 701 are respectively connected and fixed to the other output shaft of the driving motor 4 and the bottom connecting shaft 601. The two synchronous pulleys 702 are set to be of different sizes. A supporting structure 8 for limiting the object placing structure 3 and the intermittent structure 6 is fixed on the upper surface of the workbench 1; As Figure 6 shown, the supporting structure 8 includes a first supporting frame 801 and a second supporting frame 802 fixed on the upper surface of the workbench 1. The first supporting frame 801 is in a concave shape, and the second supporting frame 802 is in an L shape.

[0028] To fix the thin film, as Figure 1 、 Figure 3 、 Figure 8 and Figure 9As shown in the figure, the vacuum structure 9 includes a piston cylinder 901 fixed to the upper surface of the workbench 1, an adsorption cover 902 fixedly arranged in the annular groove 306, a piston block 903 slidably arranged inside the piston cylinder 901, a connecting pipe 907 and an air extraction pipe 904 fixedly communicated with the outer surface of the piston cylinder 901. Among them, the air extraction pipe 904 is communicated with the adsorption cover 902. The adsorption cover 902 is fan-shaped in appearance, and the adsorption cover 902 is in contact with the inner top wall of the annular groove 306. The adsorption cover 902 is in contact with the inner top wall of the annular groove 306, and a docking hole 906 adapted to the suction hole 304 is provided inside. This design ensures that the adsorption cover 902 can be closely attached above the film, and the film is firmly adsorbed in the placement groove 302 through the suction hole 304 and the docking hole 906. A docking hole 906 adapted to the suction hole 304 is provided inside the adsorption cover 902. A piston rod 905 extending outside the piston cylinder 901 is fixed to the outer surface of the piston block 903. A connecting block 10 is installed between the piston rod 905 and the transmission structure 5. Check valves 909 are installed on both the piston block 903 and the air extraction pipe 904. A mounting shaft 908 fixed to the connecting frame 305 is fixed to the outer surface of the adsorption cover 902. Through the cooperation of components such as the piston cylinder 901, the piston block 903, the connecting pipe 907 and the air extraction pipe 904, strong adsorption and fixation of the film are achieved. This design not only improves the stability of the film during the experiment but also avoids experimental errors caused by film movement. Through the coordinated operation of the drive motor 4, the transmission structure 5, the intermittent structure 6 and the vacuum structure 9, the automation and high efficiency of the experimental process are realized. This design not only improves the experimental efficiency but also reduces the labor intensity of the operator.

[0029] It should be noted that the rotating shaft connecting the placement seat 301 and the first support frame 801 is a hollow shaft, and at the same time, the mounting shaft 908 is also a hollow shaft for the connecting pipe 907 to communicate. The mounting shaft 908 penetrates through the inside of the rotating shaft, and the mounting shaft 908 can be rotatably connected to the rotating shaft so that the connecting pipe 907 will not be wound when the placement seat 301 rotates. The connecting pipe 907 is a vacuum hose. The inside of the adsorption cover 902 is hollow.

[0030] As Figure 1 - Figure 9 As shown in the figure, the principle of the polyester film puncture experiment device provided in this embodiment is as follows: When the present invention is in use, first place the polyester film to be tested in the placement groove 302 of the placement structure 3, and snap both sides thereof into the card slots in the placement groove 302 to ensure that the film covers the puncture groove 303 and the suction holes 304, and at the same time achieve preliminary fixation thereof. Start the drive motor 4. One output shaft drives the puncture experiment structure 2 to move up and down reciprocally through the transmission structure 5, and the experimental puncture needle 202 performs a puncture experiment on the film. The other output shaft controls the intermittent rotation of the placement structure 3 through the synchronization structure 7 and the intermittent structure 6, so that the next placement groove 302 moves to directly below the puncture experiment structure 2 to prepare for the next experiment; the intermittent cooperation between the groove plate 602 and the groove wheel 603, and the intermittent cooperation between the dial rod 605 and the radial groove 606 ensure the stable rotation and positioning of the placement seat 301, so that the placement seat 301 rotates a certain angle after each puncture experiment to align the new film position with the experimental puncture needle 202, greatly improving the experimental efficiency; When the drive motor 4 drives the transmission structure 5, the swinging crank 501 makes a circular motion, drives the slide block 508 to move back and forth through the connecting rod 502. When the slide block 508 moves, the roller 5092 connected to the experimental frame 201 rolls in the adjustment chute 5081. When the slide block 508 slides to the rightmost side, the roller 5092 is displaced to the lowest position of the adjustment chute 5081, thereby driving the puncture experiment structure 2 to move upward. At this time, the experimental puncture needle 202 on the puncture experiment structure 2 performs a puncture experiment on the film; When the slide block 508 is displaced, it will drive the guide rod 505 to move back and forth. The movement of the guide rod 505 starts the vacuum structure 9 through the connecting block 10. At this time, the piston block 903 in the vacuum structure 9 reciprocates in the piston cylinder 901, continuously changing the pressure in the piston cylinder 901. Cooperating with the two check valves 909, the functions of suction vacuum and blowing are realized. When the piston block 903 moves outward from the piston cylinder 901, the vacuum function is realized. At this time, the experimental puncture needle 202 moves downward, generates suction through the adsorption cover 902, and tightly adsorbs and fixes the film in the placement groove 302, so that the film can stably enable the experimental puncture needle 202 to perform a puncture experiment. When the slide block 508 moves to the right, at this time the piston block 903 moves into the piston cylinder 901, the experimental puncture needle 202 moves upward, and the piston block 903 moves into the piston cylinder 901 to blow air, thereby blowing up the tested film and automatically withdrawing it from the card slot. With the rotation of the placement structure 3, the function of automatic discharging is realized.
