Since the middle part of the wedge rod 3 is inclined, the pressure plate 32 drives the upper detection frame 33 to move downward under the obstruction of the wedge rod 3, and the second spring 34 is compressed. When the upper detection frame 33 contacts the lower detection frame 33, the detection frames 33 on the upper and lower sides clamp the mica paper. When the detection frame 33 moves outward, the detection frame 33 pulls the mica paper outward to measure the maximum load of the mica paper when it is subjected to tension.

[0035] After the detection is completed, the sliding frame 21 of the electric slide rail 2 is controlled to drive the V-shaped guide rail 22 to move upward and reset, and then the electric slide rail 2 is closed, and the V-shaped guide rail 22 drives the first slider 23, the first transverse guide rail 24, the second slider 25, the first spring 26 on the upper side, the first roller 27 on the upper side, the vertical rod 28, the guide plate 31, the pressure plate 32, the upper detection frame 33, the second spring 34 and the first sliding rod to move upward and reset.

The fixing plate (4) is rotatably connected to a gear (53), the racks (5) are meshed with the gears (53), the second support plate (43) is rotatably connected to symmetrically distributed second rollers (54), the second rollers (54) are in contact with the push rod (51), the first support plate (11) is slidably connected to a contact block (55), the contact block (55) is fixedly connected to the rack (5) sliding on the first support plate (11), and a fifth spring (56) is installed between the contact block (55) and the first support plate (11).

6. A mica paper mechanical strength testing device according to claim 5, characterized in that: The side of the contact block (55) close to the electric slide rail (2) is an inclined surface.

7. A mica paper mechanical strength testing device according to claim 6, characterized in that: It also includes an adsorption component for fixing the mica paper, the adsorption component is arranged on the fixed plate (4), the adsorption component includes a pull rod (6), a suction cup (61) and a hollow tube (62), the fixed plate (4) is fixedly connected to the hollow tube (62), the pull rod (6) is slidably connected inside the hollow tube (62), and the hollow tube (62) is connected to the suction cup (61).

8. A method for using the mica paper mechanical strength testing device according to claim 7, comprising the following steps: S1, laying mica paper on the second support plate (43), pulling the pull rod (6) to allow the suction cup (61) to fix the mica paper; S2. During the inspection, the pull rod (6) is pushed upward to make the suction cup (61) release the mica paper, and the electric slide rail (2) drives the V-shaped guide rail (22) to move through the sliding frame (21). The V-shaped guide rail (22) drives the first roller (27) to clamp the mica paper. Subsequently, under the guidance of the V-shaped guide rail (22), the first roller (27) flattens the mica paper: S3, the second slider (25) drives the vertical rod (28) to be inserted into the insertion hole of the third slider (251), the second slider (25) drives the detection frame (33) to move horizontally through the guide plate (31), and the detection frame (33) is driven to contact each other under the cooperation of the wedge rod (3) and the pressure plate (32), and at the same time, the second slider (25) drives the third slider (251) and the detection frame (33) to move horizontally through the vertical rod (28) to measure the maximum load of the mica paper when it is subjected to tension; S4, the V-shaped guide rail (22) pushes the contact block (55) to move horizontally, and under the cooperation of the gear (53) and the rack (5), the push rod (51) drives the second roller (54) to rotate and smooth the mica paper through friction.
