[0024] Reference Figure 1 and Figure 2 A membrane puncture test device comprises a machine box, a membrane fixing plate 100 and a translation device 200, wherein the membrane fixing plate 100 is connected to the machine box, a through hole 110 penetrating in the horizontal direction is arranged in the middle of the membrane fixing plate 100, and the number of the membrane fixing plates 100 is not less than two; the translation device 200 is arranged on the machine box, and the translation device 200 is transmission-connected with a push frame 210, and the translation device 200 can drive the push frame 210 to approach or move away from the membrane fixing plate 100, and the positions of the push frame 210 facing the multiple through holes 110 are respectively connected with puncture rods 220.

[0025] As can be seen from the above, the membrane to be tested is fixed on the membrane fixing plate 100, and the membrane covers the position of the through hole 110 of the membrane fixing plate 100. Different membranes can also be fixed on different membrane fixing plates 100 to directly realize comparative testing. During operation, the translation device 200 provides a reciprocating driving force for the push frame 210, first driving the push frame 210 close to the membrane fixing plate 100, so that the multiple puncture rods 220 on the push frame 210 are respectively pressed against the membranes of the multiple membrane fixing plates 100. As the push frame 210 drives the multiple puncture rods 220 to gradually apply pressure to the membrane, the multiple puncture rods 220 can be respectively penetrated into the multiple through holes 110, and the multiple membranes are stretched and extended. At this time, the stretching and deformation of the membrane under the pressure of the puncture rods 220 can be observed. In this way, the tensile and ductility properties of different membranes can be intuitively observed, and different membranes can be tested and compared at the same time, further improving the convenience of displaying membrane performance, and the overall structure is simple, the production cost is low, and it can be better promoted and applied.

[0026] When the machine box is in use, it is necessary to install electrical components such as a control panel on its surface or internal position. As for its specific structural setting, in the present embodiment, the machine box includes a base 310 and a cover plate 320, the translation device 200 is connected to the base 310, the cover plate 320 is connected to the top side of the base 310, and a limiting hole 321 and an avoidance hole 322 are provided on the cover plate 320. The limiting hole 321 extends along the movable direction of the push frame 210, and a sliding limit is formed between the push frame 210 and the limiting hole 321. The membrane fixing plate 100 passes through the avoidance hole 322 and is connected to the base 310. In actual application, there can be only one avoidance hole 322. At this time, multiple membrane fixing plates 100 are connected to the base 310 through the avoidance hole 322, or the number of avoidance holes 322 and membrane fixing plates 100 corresponds to each other, and multiple membrane fixing plates 100 are respectively connected to the base 310 after passing through multiple avoidance holes 322. The base 310 is used for the placement and fixation of the whole. The translation device 200 can be installed on the base 310. A cover plate 320 is also installed on the base 310. The cover plate 320 can cover and decorate the top side of the base 310. The membrane fixing plate 100 passes through the avoidance hole 322 on the cover plate 320 and is then installed in the base 310 for fixation. There is also a sliding limitation between the push frame 210 and the cover plate 320. In this way, the translation device 200 can move closer to or away from the membrane fixing plate 100 along the limiting hole 321 when driving the push frame 210 to move, thereby further improving the stability of the movement of the puncture rod 220.

[0027] The sliding restriction formed between the push frame 210 and the limiting hole 321 can be that the push frame 210 is directly set on the top side of the cover plate 320, and a slider structure protruding toward the limiting hole 321 is formed on the push frame 210, and the sliding restriction is formed between the push frame 210 and the cover plate 320 through the sliding cooperation between the slider and the limiting hole 321. In order to reduce the exposure of the driving structure, a groove structure for accommodating the transmission connection part of the translation driving device and the push frame 210 can be formed on the base 310. Specifically, a fixed The fixed groove 311, the cover plate 320 covers the fixed groove 311, and a limiting hole 321 is arranged on the cover plate 320 at a position opposite to the fixed groove 311, and two limiting holes 321 are arranged at intervals along its width direction. The push frame 210 includes a cross bar and a vertical bar, and the translation device 200 is transmission-connected to the cross bar, and the cross bar is located in the fixed groove 311. The two vertical bars are connected to the cross bar and extend upward from the two limiting holes 321 respectively, and the two vertical bars are respectively connected to the puncture rods 220. A space for accommodating the movable part of the translation device 200 is provided on the top side of the base 310, and the cover plate 320 is used to cover it, so as to reduce the exposure of the movable structure, improve the overall appearance, and reduce external interference during operation. At this time, the cross bar is installed in the fixing groove 311, and is connected to the translation device 200 through the cross bar. A vertical rod for fixing the puncture rod 220 is connected to the cross bar. The number of vertical rods can be set according to the number of puncture rods 220. For example, when two puncture rods 220 are needed, two vertical rods are connected, and the vertical rods extend upwardly through the limiting hole 321. The vertical rod is limited by the limiting hole 321, so as to realize the sliding limitation between the push frame 210 and the limiting hole 321, and improve the stability of the activity of the puncture rod 220.

[0028] The end of the puncture rod 220 facing the through hole 110 is a tapered structure, which makes it convenient to apply puncture force to the membrane. Different puncture shapes will have different puncture effects. In order to facilitate the replacement of the puncture rod 220, in actual applications, the puncture rod 220 and the vertical rod are detachably connected, which makes it convenient to replace and maintain the puncture rod 220. For example, the puncture rod 220 and the vertical rod are connected to each other by means of a buckle and a slot, or the puncture rod 220 is connected to the vertical rod by a threaded connection. In order to facilitate the application of force to the puncture rod 220, a thread may be provided on the outside of the puncture rod 220 to facilitate the rotation of the puncture rod 220.

[0029] The translation device 200 is mounted on the bottom cover and can be directly exposed. In order to better protect its driving structure, in this embodiment, the machine box further includes a cover box 330, which is connected to the top side of the base 310 and covers the translation device 200. The cover box 330 covers the translation device 200, which can reduce the exposure of the driving structure, better protect the translation device 200, and improve the overall appearance.

[0030] In the above embodiment, the membrane fixing plate 100 can be directly fixed on the base 310 and cannot be removed. When the membrane to be tested needs to be fixed on the membrane fixing plate 100, it needs to be fixed directly on the whole machine. In order to improve the installation efficiency of the membrane fixing plate 100, in this embodiment, the membrane fixing plate 100 and the base 310 are detachably connected. When the membrane to be tested needs to be fixed on the membrane fixing plate 100, the membrane fixing plate 100 can be removed first. At this time, the membrane to be tested can be fixed on the membrane fixing plate 100 by bonding or clamping, and then the membrane fixing plate 100 can be reinstalled on the base 310 to improve the convenience of installation.

[0031] There are many ways to detachably connect the membrane fixing plate 100 and the base 310. For example, a positioning pin is driven into one side of the base 310 and inserted into the membrane fixing plate 100, so that the membrane fixing plate 100 and the base 310 are relatively fixed. When it is necessary to remove it, the membrane fixing plate 100 can be separated from the base 310, or the membrane fixing plate 100 can be connected and fixed to each other by means of the mutual cooperation of the buckle and the slot. In this embodiment, the top side of the base 310 is provided with a positioning slot 312, and two positioning slots 312 are arranged at intervals along the width direction of the limiting hole 321, and the bottoms of the two membrane fixing plates 100 are respectively inserted into the two positioning slots 312. There are two membrane fixing plates 100, and two different membranes can be tested comparatively. The two membrane fixing plates 100 are respectively connected to the positioning slots 312 on the top side of the base 310 through their bottoms, so that disassembly and assembly positioning can be easily achieved. In actual applications, the bottoms of the two membrane fixing plates 100 are connected in the two positioning grooves 312 with an interference fit, thereby improving the stability of the installation and fixation of the two membrane fixing plates 100. When the membrane is stretched and deformed by the top pressure of the puncture rod 220, the two membrane fixing plates 100 will not shake, thereby improving the accuracy of the test.

[0032] In the above embodiment, the tensile and elongation performance of the membrane is judged only by directly observing the situation when the membrane is deformed by the puncture needle. In order to better quantify its performance index, in this embodiment, a ruler 323 is provided on the top side of the cover plate 320, which is located beside the membrane fixing plate 100. The ruler 323 can be provided beside a membrane fixing plate 100, or between two membrane fixing plates 100. The length of the membrane stretched by the puncture needle can be intuitively observed through the ruler 323, so as to better quantify the tensile and elongation performance of the membrane and improve the experience of the test display.

[0033] The translation device 200 is mainly used to provide a driving force for the reciprocating movement of the push frame 210. There are many structural forms, such as electric screws, cylinders or hydraulic cylinders, etc. In order to better adjust and control the movement of the puncture rod 220, in this embodiment, the translation device 200 is an electric push rod. The electric push rod provides a driving force to the push frame 210, which can smoothly drive the puncture rod 220 to move, and the direction of travel is better controlled.

[0034] Furthermore, the machine box is provided with a switch button 341 and a speed regulating button 342, and the switch button 341 and the speed regulating button 342 are electrically connected to the electric push rod. When the operation of the electric push rod needs to be controlled, the start and stop of the electric push rod can be controlled by the switch button 341, and the driving force provided to the puncture rod 220 can be adjusted by the speed regulating button 342, so as to adjust the magnitude of the puncture force provided to the membrane, which is more flexible and convenient during testing. In practical applications, there are many types of switch buttons 341, which can be a main switch for controlling the activity of the electric push rod, a forward switch for controlling the electric push rod to drive the push frame 210 to move in a direction close to the membrane fixing plate 100, or a backward switch for controlling the electric push rod to drive the push frame 210 to move in a direction away from the membrane fixing plate 100, which can be configured according to the needs of use.

[0035] In some embodiments, the machine box is detachably connected with a display board 350, which can be connected to the machine box by means of a buckle and a slot, or fixed to the machine box by means of a connection such as a screw. In practical applications, the display board 350 can be a tablet, on which only the test information and the whole machine test content are recorded, or an electronic display board, which can display real-time test information, such as the torque and speed of the puncture rod 220, to further improve the test display experience.
