The precise coordination of the synchronous structure and the intermittent structure ensures the smooth rotation and precise positioning of the placement structure, so that the position of the film can be accurately aligned in each experiment.
[0024] 2. The polyester film puncture test equipment ensures the smooth rotation and positioning of the storage base through the intermittent cooperation between the groove plate and the groove wheel, as well as the intermittent cooperation between the lever and the radial groove.

The check valve is used to achieve vacuum suction and air blowing. When the piston block moves toward the outside of the piston cylinder, suction is generated to firmly adsorb and fix the film in the storage slot. This stable fixing method ensures the stability of the film during the puncture test and avoids experimental errors caused by film movement or deformation.
[0026] 4. The polyester film puncture test equipment drives the connecting rod and slide to move back and forth by swinging the crank in a circular motion, thereby controlling the up and down movement of the puncture test structure. This precise control method ensures the consistency of the speed, force and angle of the puncture needle during the puncture test, improving the accuracy and repeatability of the test. The automated process reduces the chance of manual operation, thereby reducing the impact of human factors on the test results, which helps to ensure the objectivity and accuracy of the test results.

DETAILED DESCRIPTION
[0038] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0039] like Figure 1 - Figure 9 As shown, the polyester film puncture experimental equipment provided in this embodiment includes a puncture experimental structure 2 installed on a workbench 1, wherein the puncture experimental structure 2 includes an experimental frame 201 arranged above the workbench 1 and an experimental puncture needle 202 detachably installed on the experimental frame 201, and the experimental frame 201 is L-shaped. The puncture experimental structure 2 belongs to the conventional technology known to the public in the prior art, so its specific structural composition and working principle will not be described in detail in this article. The experimental puncture needle 202 is detachably installed on the experimental frame 201, which is convenient for replacing puncture needles of different specifications and types to meet the needs of different types of film experiments. The workbench 1 is provided with a storage structure 3 and a drive motor 4 used in conjunction with the puncture experimental structure 2. A transmission structure 5 and an intermittent structure 6 for linkage use are provided between the drive motor 4 and the storage structure 3. The upper surface of the workbench 1 is also provided with a vacuum structure 9 used in conjunction with the transmission structure 5 to fix the film; as shown Figure 1 and Figure 3As shown, the storage structure 3 includes a storage seat 301, and six surfaces are equidistantly arranged on the storage seat 301, and each of the six surfaces is provided with a storage slot 302. The storage slot 302 is provided with a puncture slot 303 and a suction hole 304 used in conjunction with the vacuum structure 9. Among them, the top storage slot 302 is located directly below the puncture test structure 2. The puncture test structure 2 is driven by the motor 4 and the transmission structure 5 to achieve up and down reciprocating movement to realize the puncture experiment on the film. The storage seat 301 is hexagonal in shape. This design allows users to easily place and replace samples. At the same time, the combination of the suction hole 304 and the vacuum structure 9 ensures the stability of the sample during the experiment. Two relatively distributed card slots are provided on the inner side of the storage slot 302 for preliminary fixing of the film when it is placed. At the same time, the puncture slot 303 is opened in the storage slot 302 to facilitate the puncture experiment of the experimental puncture needle 202. There are several suction holes 304 and they are symmetrically arranged on both sides of the puncture slot 303.
[0040] In this embodiment, the drive motor 4 is a dual-axis motor. One of the output shafts of the drive motor 4 is connected to the transmission structure 5, and a synchronization structure 7 is provided between the other output shaft of the drive motor 4 and the intermittent structure 6. The drive motor 4 is a dual-axis motor. One output shaft drives the transmission structure 5 to achieve the up and down reciprocating movement of the puncture experimental structure 2, and the other output shaft controls the intermittent rotation of the placement structure 3 through the synchronization structure 7 and the intermittent structure 6. This design makes the experimental process highly automated and greatly improves the experimental efficiency. Figure 6 As shown, the synchronization structure 7 includes a fixedly connected synchronization shaft 701 and a synchronization wheel 702, and there are two synchronization shafts 701 and two synchronization wheels 702, and a synchronization belt 703 is connected between the two synchronization wheels 702. The motor seat 41 on which the drive motor 4 is installed is fixed on the upper surface of the workbench 1. Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the transmission structure 5 includes a swinging member, a sliding member and a guiding member, wherein a sliding shaft member 509 is installed between the sliding member and the experimental frame 201, and the sliding shaft member 509 includes a shaft 5091 fixed to the outer surface of the experimental frame 201 and a roller 5092 rotatably installed at the other end of the shaft 5091; the swinging member includes a swing crank 501 fixed on the output shaft of the driving motor 4, and a connecting rod 502 hingedly installed at the bottom end of the swing crank 501.
[0041] To achieve the up and down reciprocation of the experimental puncture needle 202, as shown in FIG. Figure 4 and Figure 5As shown, the sliding member includes a slide 508 positioned above the workbench 1 and a connecting shaft 503 fixed to the front of the slide 508. The right end of the connecting rod 502, away from the swing crank 501, is hinged to the end of the connecting shaft 503. The slide 508 has an adjustment slot 5081 formed inside for use with a roller 5092. The outer surface of the roller 5092 is in rolling engagement with the inner side of the adjustment slot 5081. Through the precise coordination of the swing crank 501, connecting rod 502, slide 508, and roller 5092, precise up and down reciprocating movement of the experimental puncture needle 202 is achieved. This design ensures consistency in force and speed during the puncture process, thereby improving the accuracy and repeatability of the experiment.
[0042] In order to improve the lifting stability of the experimental puncture needle 202, Figure 2 、 Figure 4 and Figure 5 As shown, the guide member includes two limit seats 504 fixed to the upper surface of the workbench 1, a guide rod 505 that slides through the two limit seats 504, and a sleeve 506 fixed to the outer surface of the guide rod 505. A slide seat 508 is welded to the outer surface of the sleeve 506. A first buffer spring 507 is fixed between the sleeve 506 and the left limit seat 504 and surrounds the outer surface of the guide rod 505. The guide member also includes a limit ear 510 fixed to the outer surface of the laboratory rack 201 and a guide rod 511 fixed to the upper surface of the workbench 1. The top end of the guide rod 511 extends through the limit ear 510. A second buffer spring 512 is fixed between the lower surface of the limit ear 510 and the guide rod 511. The second buffer spring 512 surrounds the outer surface of the guide rod 511. The guide member includes the limit seats 504, the guide rod 505, the sleeve 506, and the first buffer spring 507. These components together ensure the stability of the laboratory puncture needle 202 during the raising and lowering process. In addition, the addition of the stopper 510, the guide rod 511 and the second buffer spring 512 further enhances the stability of the experimental frame 201, thereby ensuring the accuracy of the experimental results. In addition, the installation of the second buffer spring 512 can be detached as needed to better perform the puncture experiment.
[0043] like Figure 3 、 Figure 6 and Figure 7 As shown, in this embodiment, an annular groove 306 is opened inside the storage seat 301 and communicates with the outside. A connecting frame 305 with a cross shape and used to connect to the intermittent structure 6 is bolted to the outer surface of the storage seat 301. There are two connecting frames 305, which are respectively located on the left and right sides of the annular groove 306. Figure 7As shown, the intermittent structure 6 includes two connecting shafts 601 and a grooved plate 602 and a grooved wheel 603 fixed to the two connecting shafts 601. The grooved plate 602 and the grooved wheel 603 intermittently cooperate with each other, wherein the connecting shaft 601 connected to the grooved plate 602 is fixed to the outer surface of the connecting frame 305. In addition, a swing arm 604 is fixed to the connecting shaft 601 connected to the grooved wheel 603, and a lever 605 is mounted on the other end of the swing arm 604. The grooved plate 602 is internally provided with a plurality of equidistant and open radial grooves 606, and the lever 605 intermittently cooperates with the radial grooves 606. The intermittent cooperation between the radial grooves 606 on the grooved plate 602 and the lever 605 enables intermittent rotation of the storage seat 301. This design not only simplifies the transmission mechanism, but also improves the accuracy and stability of the rotation, ensuring the sequential and orderly testing of the films during the experiment.
[0044] 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 wheels 702 are set in different sizes, and the upper surface of the workbench 1 is fixed with a support structure 8 limited by the opposing structure 3 and the intermittent structure 6; Figure 6 As shown, the support structure 8 includes a first support frame 801 and a second support frame 802 fixed to the upper surface of the workbench 1. The first support frame 801 is concave in shape, and the second support frame 802 is L-shaped.
[0045] To achieve the fixation of the film, Figure 1 、 Figure 3 、 Figure 8 and Figure 9As shown, 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, and a connecting pipe 907 and an exhaust pipe 904 fixedly connected to the outer surface of the piston cylinder 901, wherein the exhaust pipe 904 is connected to the adsorption cover 902, the adsorption cover 902 is fan-shaped, 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 is provided with a docking hole 906 adapted to the suction hole 304. This design ensures that the adsorption cover 902 can fit tightly above the film and firmly adsorb the film into the storage groove 302 through the suction hole 304 and the docking hole 906. A docking hole 906 that matches the suction hole 304 is provided inside the adsorption cover 902. A piston rod 905 extending to the outside of 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. A check valve 909 is installed on the piston block 903 and the exhaust pipe 904. A mounting shaft 908 fixed to the outer surface of the adsorption cover 902 is fixed to the connecting frame 305. Through the cooperation of components such as the piston cylinder 901, the piston block 903, the connecting pipe 907 and the exhaust pipe 904, a strong adsorption and fixation of the film is achieved. This design not only improves the stability of the film during the experiment, but also avoids experimental errors caused by the movement of the film. Through the coordinated work of the drive motor 4, the transmission structure 5, the intermittent structure 6 and the vacuum structure 9, the automation and efficiency of the experimental process are achieved. This design not only improves the experimental efficiency, but also reduces the labor intensity of the operator.
[0046] It should be noted that the rotating shaft connecting the storage base 301 to the first support frame 801 is a hollow shaft, and the mounting shaft 908 is also a hollow shaft to facilitate communication with the connecting tube 907. The mounting shaft 908 extends through the interior of the rotating shaft and is rotatably connected to the rotating shaft, preventing the connecting tube 907 from becoming entangled when the storage base 301 rotates. The connecting tube 907 is a vacuum hose. The interior of the adsorption cover 902 is hollow.
[0047] like Figure 1 - Figure 9 As shown, the principle of the polyester film puncture test equipment provided in this embodiment is as follows:
[0048] When the present invention is used, the polyester film to be tested is first placed in the storage slot 302 of the storage structure 3, and both sides of the polyester film are clamped into the clamping slots in the storage slot 302 to ensure that the film covers the puncture slot 303 and the suction hole 304, and at the same time achieves its preliminary fixation, and the drive motor 4 is started. An output shaft drives the puncture test structure 2 to move up and down through the transmission structure 5, and the experimental puncture needle 202 performs a puncture test on the film. The other output shaft controls the intermittent rotation of the storage structure 3 through the synchronization structure 7 and the intermittent structure 6, so that the next storage slot 302 moves to the right under the puncture test structure 2, ready for the next experiment; the intermittent cooperation of the groove plate 602 and the groove wheel 603, and the intermittent cooperation of the shifting rod 605 and the radial groove 606 ensure the smooth rotation and positioning of the storage seat 301, so that the storage seat 301 rotates a certain angle after each puncture test, and the new film position is aligned with the experimental puncture needle 202, which greatly improves the experimental efficiency;
[0049] When the driving motor 4 drives the transmission structure 5, the swing crank 501 performs a circular motion, which drives the slide 508 to reciprocate back and forth through the connecting rod 502. When the slide 508 moves, the roller 5092 connected to the experimental frame 201 rolls in the adjustment slot 5081. When the slide 508 slides to the extreme right, the roller 5092 moves to the lowest position of the adjustment slot 5081, thereby driving the puncture test structure 2 to move upward. At this time, the experimental puncture needle 202 on the puncture test structure 2 performs a puncture test on the film.
[0050] When the slide 508 is displaced, it will drive the guide rod 505 to move back and forth. The guide rod 505 moves through the connecting block 10 to start the vacuum structure 9. At this time, the piston block 903 in the vacuum structure 9 then reciprocates in the piston cylinder 901 to continuously change the pressure in the piston cylinder 901, and cooperates with the two sets of check valves 909 to realize the suction vacuum and blowing effects. When the piston block 903 moves toward the outside of the piston cylinder 901, a vacuum effect is realized. At this time, the experimental puncture needle 202 moves downward, and the suction cover 902 generates suction to tightly adsorb and fix the film in the storage groove 302, so that the film can stabilize the experimental puncture needle 202 for puncture experiments. When the slide 508 moves to the right, the piston block 903 moves into the piston cylinder 901, and the experimental puncture needle 202 moves upward. 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. As the storage structure 3 rotates, an automatic discharge effect is realized.
