Technical Field
[0001] The utility model relates to the technical field of nuclear pore membrane pressing, in particular to a nuclear pore membrane pressing device with a rapid positioning structure. Background Art
[0002] Nuclear pore membrane, also known as track-etched membrane, is made of polyester film (PET), which is made of polyethylene terephthalate, extruded into thick sheets, and then biaxially stretched into thin films. It uses high-energy particles accelerated by an accelerator to penetrate organic polymer plastic films and leave a narrow irradiation channel - track - on the path. The tracks on the film can be etched into micropores by etching with appropriate chemical reagents. The nuclear pore membrane can be used to adjust the humidity inside the fresh food storage box during fresh food transportation, so that the fresh food can be kept fresh for a longer time. When using the nuclear pore membrane, the nuclear pore membrane needs to be pressed tightly on the fixing component, and the fixing component must be fixed at the installation position when in use before it can be used.

A first guide slide bar 19 is slidably provided in a rectangular perforation on one side of the movable plate 18. The first guide slide bar 19 is fixed on one side of the fixed plate at the bottom end of the inner side of the main frame 11. A tension spring 20 is fixed between one side of the fixed plate and one side of the movable plate 18. A driving mechanism for driving the movable plate 18 to move is provided at the bottom end of the inner side of the main frame 11. A correction mechanism for correcting the position of the fixed component is provided at the upper end of the inner side of the main frame 11. The driving mechanism facilitates the movable plate 18 to move so that the two positioning plates 15 clamp and limit the fixed component. The correction mechanism facilitates the alignment of the fixed component with the upper template 12.
[0024] The driving mechanism includes two symmetrically arranged connecting rods 21, one end of the connecting rod 21 is rotatably connected to one side of the moving plate 18, and the other end of the connecting rod 21 is rotatably connected to one end of the horizontal plate on one side of the guide plate 22. A fixed groove rod 29 is slidably provided at the bottom end of the guide plate 22, and the fixed groove rod 29 is fixedly arranged at the bottom end of the inner side of the main frame 11. A push rod 23 is tightly arranged at the inclined surface of the upper end of the guide plate 22, and the push rod 23 is fixedly arranged on the output end of the electric push rod 13. When in use, when it is necessary to press the nuclear pore membrane, the fixed component is placed on the upper end of the lower template 14, and the nuclear pore membrane is placed inside the fixed component. Then the electric push rod 13 is started, and the output end of the electric push rod 13 drives the upper template 12 and the push rod 23 to move. The push rod 23 is in close contact with the inclined surface of the guide plate 22. When the push rod 23 moves, it pushes the guide plate 22 to slide inside the fixed groove rod 29. When the fixed groove rod 29 slides, the two movable plates 18 are pulled to slide through the connecting rod 21. The movable plate 18 drives the two positioning plates 15 to move through the adjusting rod 16. The two positioning plates 15 move in opposite directions. When one end of the push rod 23 is in close contact with the plane on one side of the guide plate 22, the two positioning plates 15 symmetrically fix the parts to clamp and limit, so that the fixing parts are coaxially arranged with the upper template 12.
[0025] A ball bearing is provided at one end of the push rod 23, which is convenient for reducing the wear between the one end of the push rod 23 and the guide plate 22 during use.
[0026] A first roller is rotatably disposed in the mounting groove at the bottom end of the movable plate 18, so that the movable plate 18 can be easily moved when in use.
[0027] Second rollers are rotatably disposed in a plurality of mounting grooves on the inner side of the positioning plate 15 , so that when in use, the fixing component can be rotated when the positioning plate 15 clamps and limits the fixing component.
[0028] The correction mechanism includes a correction plate 24, which is arranged above the lower template 14. The correction plate 24 is fixed to one end of the support frame, and the support frame is fixed to the bottom end of the mounting plate. The mounting plate is fixed to one side of the first friction plate 25. A second guide slide bar 26 is slidably provided in a rectangular perforation on one side of the mounting plate. The second guide slide bar 26 is fixed to the upper end of the inner side of the main frame body 11. A first friction wheel is frictionally provided at the bottom end of the first friction plate 25. The first friction wheel is fixed to one end of the fixed shaft, and a rotating plate is rotatably provided on the fixed shaft. The rotating plate is fixed to the upper end of the inner side of the main frame body 11, and a second friction wheel is fixed to the other end of the fixed shaft. A second friction plate 28 is frictionally provided on the second friction wheel. The second friction plate 28 is fixed to one side of the fixed frame 27, and the fixed frame 27 is fixed to the output shaft of the electric push rod 13. A placement groove is provided at the corresponding positions of the upper end of the inner side of the main frame body 11 and the fixed frame 27 and the second friction plate 28. When in use When the output end of the electric push rod 13 drives the upper template 12 to press the nuclear pore membrane, the output end of the electric push rod 13 drives the push rod 23 and the fixed frame 27 to move, and the fixed frame 27 drives the second friction plate 28 to move. When one side of the second friction plate 28 is in close contact with the second friction wheel, the second friction plate 28 drives the first friction wheel to rotate through the second friction wheel, and the first friction wheel drives the correction plate 24 to move through the first friction plate 25. When one end of the push rod 23 contacts the plane of the guide plate 22, one end of the correction plate 24 contacts the fixed column inside the fixed component. If the fixed column is not aligned with the circular perforation on the upper template 12, the correction plate 24 drives the fixed component to rotate. When the fixed column is aligned with the circular perforation on the upper template 12, the correction plate 24 no longer drives the fixed component to rotate. When the upper template 12 presses the nuclear pore membrane, the correction plate 24 moves to a position symmetrical to the initial position. When the upper template 12 is pressed and returns to the initial position, the second friction wheel and the first friction wheel rotate in opposite directions, so that the correction plate 24 moves to the initial position.
[0029] An adjusting nut 17 is rotatably provided at a position corresponding to the position of the adjusting rod 16 on one side of the movable plate 18, a threaded hole is provided on one side of the adjusting nut 17, and an external thread is provided on the adjusting rod 16. When in use, when it is necessary to clamp and limit the fixed parts of different diameters, the adjusting nut 17 is rotated, and the initial position of the positioning plate 15 is adjusted under the action of the thread, so that the fixed parts of different diameters can be limited.
[0030] The above embodiment discloses a nuclear pore membrane pressing device with a rapid positioning structure, wherein, when the nuclear pore membrane needs to be pressed, the fixed component is placed on the upper end of the lower template 14, and the nuclear pore membrane is placed inside the fixed component, and then the electric push rod 13 is started, and the output end of the electric push rod 13 drives the upper template 12 and the push rod 23 to move, and the push rod 23 is in close contact with the inclined surface of the guide plate 22. When the push rod 23 moves, it pushes the guide plate 22 to slide inside the fixed groove rod 29, and when the fixed groove rod 29 slides, the two moving plates 18 are pulled to slide through the connecting rod 21, and the moving plate 18 drives the two positioning plates 15 to move through the adjusting rod 16, and the two positioning plates 15 move in opposite directions. When one end of the push rod 23 is in close contact with the plane of one side of the guide plate 22, the two positioning plates 15 clamp and limit the fixed component, so that the fixed component is coaxially arranged with the upper template 12, and at the same time, the output end of the electric push rod 13 drives the fixing frame 27 to move, and the fixing The frame 27 drives the second friction plate 28 to move. When one side of the second friction plate 28 is in close contact with the second friction wheel, the second friction plate 28 drives the first friction wheel to rotate through the second friction wheel. The first friction wheel drives the correction plate 24 to move through the first friction plate 25. When one end of the push rod 23 contacts the plane of the guide plate 22, one end of the correction plate 24 contacts the fixed column inside the fixed component. If the fixed column is not aligned with the circular perforation on the upper template 12, since a plurality of first rollers are provided on the inner side of the positioning plate 15, the correction plate 24 drives the fixed component to rotate by pushing the fixed column. When the fixed column is aligned with the circular perforation on the upper template 12, the correction plate 24 no longer drives the fixed component to rotate. When the upper template 12 presses the nuclear pore membrane, the correction plate 24 moves to a position symmetrical to the initial position. When the upper template 12 is pressed and returns to the initial position, the second friction wheel and the first friction wheel rotate in opposite directions, thereby moving the correction plate 24 to the initial position.

Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
