On the contrary, when the support ring 22 and the protrusion 23 rotate, the top of the support column 24 corresponding to the film paper 7 to be detected slides from the bottom of the protrusion 23 to the bottom of the support ring 22, and the second compression spring 41 drives the movable sleeve 8 and the movable seat 3 to move upward synchronously, and the bottom end of the winding shaft 6 slides into the movable sleeve 8 to prevent the slider 10 from being separated from the slide groove 11, so that the winding shaft 6 is fixed relative to the first rotating shaft 4 or the second rotating shaft 5;

[0048] The top of the support column 24 located below the film paper 7 that does not need to be detected is in contact with the bottom of the protrusion 23, the bottom end of the winding shaft 6 is exposed from the movable sleeve 8, and the fixing frame 25 and the magnet block 26 corresponding to the support column 24 and the movable seat 3 are in the lowest position, the magnet block 26 is in contact with the corresponding iron plate 27, and the magnetic force generated by the magnet block 26 and the iron plate 27 is at a preset value, so that the two winding shafts 6 corresponding to the film paper 7 that does not need to be detected are fixed relative to the fixing frame 25. Similarly, the top of the support column 24 located below the film paper 7 that needs to be detected is in contact with the bottom of the support ring 22, and the fixing frame 25 and the magnet block 26 corresponding to the support column 24 and the movable seat 3 are in the highest position, and the magnet block 26 is not in contact with the corresponding iron plate 27, so that the two winding shafts 6 corresponding to the film paper 7 that needs to be detected can rotate relative to the fixing frame 25 and the movable seat 3. When the servo motor 34 drives the third gear 35 to rotate, the third gear 35 drives the corresponding fourth rotating shaft 43 and the third damping disk 44 through the fourth gear 36. Rotation, the third damping disc 44 drives the fourth damping disc 45 and the second rotating shaft 5 that are not limited to rotate through friction, and the second rotating shaft 5 can drive the winding shaft 6 to rotate relative to the movable sleeve 8 through the slider 10. The third damping disc 44 cannot drive the fixed fourth damping disc 45, the second rotating shaft 5 and the winding shaft 6 to rotate through friction. The second hydraulic telescopic rod 31 drives the movable disc 30 to move in the vertical direction, and the spacing between the movable disc 30 and the second damping disc 29 changes. The movable disc 30 slides relative to the guide column 32, and the length of the first compression spring 33 changes, changing the pressure applied by the first compression spring 33 to the second damping disc 29, thereby adjusting the friction between the second damping disc 29 and the first damping disc 28. When the second rotating shaft 5 and the winding shaft 6 pull the corresponding winding shaft 6 and the first rotating shaft 4 to rotate through the film paper 7, the winding shaft 6 drives the first damping disc 28 to rotate relative to the second damping disc 29 through the first rotating shaft 4, and the first damping disc 28 rotates to overcome the friction so that the tension of the film paper 7 during movement is within a preset range.
