The top ends of the guide rods 26 are fixedly connected to the top of the inner cavity of the protective cover 22, and the bottom ends of the guide rods 26 are fixedly connected to the top of the support frame 21.
[0023] In this embodiment, through the setting of the protective cover 22, it is convenient to protect the first motor 23, the screw rod 24, the lifting plate 25 and the guide rod 26 inside it. When the thin film is laid on the sampling table 1 and the two ends of the thin film are located below the inside of the two support frames 21, through the cooperation of the first motor 23 and the screw rod 24, it is convenient to drive the lifting plate 25 to move. By using the setting of the guide rod 26, the lifting plate 25 is vertically guided to maintain the stability of the lifting plate 25 during movement. The lifting plate 25 can drive the anti-slip pressing plate 28 to move through the pressing rod 27, so as to press the anti-slip pressing plates 28 inside the two support frames 21 against the two ends of the thin film, thereby fixing the thin film.
[0024] Embodiment Two:
[0025] As Figures 1-3 shown, a thin film sampling and cutting mechanism 3 is provided above the sampling table 1. The thin film sampling and cutting mechanism 3 includes a fixing plate 31. The two sides of the bottom of the fixing plate 31 are fixedly connected to the top of the protective cover 22. A driving groove 32 is opened at the bottom of the fixing plate 31. A driving block 35 is slidably connected inside the driving groove 32. A second motor 33 is fixedly installed at the right end of the inner cavity of the driving groove 32. The output end of the second motor 33 is fixedly connected to a lead screw 34. The left end of the lead screw 34 is rotatably connected to the left end of the inner wall of the driving groove 32. The upper part inside the driving block 35 is threadedly sleeved on the outer wall of the lead screw 34. The bottom of the driving block 35 is fixedly connected to an electric telescopic rod 36. The telescopic end of the electric telescopic rod 36 is fixedly connected to an upper knife seat 37. Two upper cutting knives 38 are fixedly installed on both sides of the bottom of the upper knife seat 37. The number of the upper cutting knives 38 is two. Two lower cutting knives 392 are arranged directly below the two upper cutting knives 38. A limiting groove 39 is opened at the top of the sampling table 1. A lower knife seat 391 is arranged inside the limiting groove 39. The number of the lower cutting knives 392 is two. The bottoms of the two lower cutting knives 392 are fixedly connected to both sides of the top of the lower knife seat 391. Two L-shaped connecting rods 393 are fixedly connected to the lower parts of the front and rear sides of the driving block 35. The number of the L-shaped connecting rods 393 is two. The bottoms of the two L-shaped connecting rods 393 are fixedly connected to both ends of the top of the lower knife seat 391.
[0026] In this embodiment, through the setting of the L-shaped connecting rods 393, it is convenient to connect the lower knife seat 391 with the driving block 35. Through the cooperation of the second motor 33, the lead screw 34 and the driving block 35, it is convenient to drive the electric telescopic rod 36, the upper knife seat 37 and the upper cutting knives 38 to move. The driving block 35 can drive the lower knife seat 391 and the two lower cutting knives 392 to move through the L-shaped connecting rods 393 at the same time, so as to conveniently adjust the position when cutting the thin film. Through the setting of the electric telescopic rod 36, it is convenient to adjust the height of the two upper cutting knives 38. The two upper cutting knives 38 can be moved downwards to contact with the two lower cutting knives 392, so as to quickly and smoothly cut the thin film and improve the flatness of the cutting part of the thin film.
[0027] In summary, as Figures 1-3 shown, when using this thin-film sampling device, first lay the thin film on the sampling table 1, and make both ends of the thin film located below the inside of the two support frames 21. At the same time, the upper cutting knife 38 is located above the thin film. At this time, the first motor 23 inside the two protective covers 22 drives the screw rod 24 to rotate. The screw rod 24 drives the lifting plate 25 to move vertically downward along the outer wall of the guide rod 26. The lifting plate 25 drives the anti-slip pressing plate 28 to move downward through the pressing rod 27, so that the anti-slip pressing plates 28 inside the two support frames 21 can be pressed against both ends of the top of the thin film to fix the thin film. Then, the output end of the second motor 33 drives the lead screw 34 to rotate. The lead screw 34 drives the driving block 35 to slide inside the driving groove 32. The driving block 35 drives the upper tool holder 37 and the two upper cutting knives 38 to move through the electric telescopic rod 36. At the same time, the driving block 35 drives the lower tool holder 391 and the two lower cutting knives 392 to move inside the limiting groove 39 through the L-shaped connecting rod 393, so as to adjust the positions of the upper cutting knife 38 and the upper and lower cutting knives 392. Then, the telescopic end of the electric telescopic rod 36 drives the two upper cutting knives 38 to move downward and contact the two lower cutting knives 392, and use the two upper cutting knives 38 and the two lower cutting knives 392 to cut the thin film quickly and smoothly. Then collect the thin film strip cut between the two upper cutting knives 38 and the two lower cutting knives 392, and the sampling can be completed.
