When the graphene heat insulation film is detected, the graphene heat insulation film is cut into a long rectangular material belt which is convenient to detect in advance. Whether tensile strength detection or anti-distortion detection is performed, the graphene heat insulation film is clamped between the two film material flat clamping devices 4, and in order to facilitate clamping operation, the two rotary drums 3 limit the rotation freedom degree through the locking component 45, the two film material flat clamping devices 4 are located at the same horizontal height and are in the horizontal state, when clamping, one end of the graphene heat insulation film is flatly unfolded and plugged between the two clamping blocks 444 of one film material flat clamping device 4, then, the output rod is contracted by starting the clamping driving cylinder 441 to drive the stroke plate 442 to slide towards one side close to the disc 31, then the two clamping blocks 444 are driven to move close by the connecting rod 445, one end of the graphene heat insulation film is clamped between the two clamping blocks 444, the operation is repeated, and the other end of the graphene heat insulation film is clamped in the other film material flat clamping device 4.

The preparation work is completed when the tensile strength detection and the anti-twisting detection are carried out, and a new graphene heat insulation film for detection needs to be replaced in the two detection processes.
After the preparation work is completed, when the tensile strength is detected, the locking assembly 45 is locked on the matching plate 421 and the rotary cylinder 3, so that the tension spring 43 cannot be stretched, the graphene heat insulation film can be always kept in a horizontal tightening state, then the stretching mechanism 2 is started again, and the graphene heat insulation film is driven to be gradually stretched and tensioned through the back displacement of the two rotary supporting platforms 22 until the graphene heat insulation film is finally stretched. In order to monitor the tensile strength in real time, because the film material flat clamping device 4 and the rotary supporting table 22 generate synchronous displacement in the supporting and pulling process, a tension sensor can be assembled on the detection workbench 1, the tension direction of the tension sensor and the sliding direction of the rotary supporting table 22 are arranged in the same direction, the tension end of the tension sensor is fixed on the rotary supporting table 22, and according to the principle that the tension detection value of the tension sensor and the displacement are in a proportional relation, when the tensile strength of the graphene thermal insulation film is detected, the tension can be fed back in real time through the tension sensor, and the critical tension value at the final stretch-out time can be detected, and the critical tension value is the maximum bearing tension, so that the tensile strength parameter of the detected graphene thermal insulation film can be detected.
After the preparation is completed, when the anti-twist flexibility test is performed, the locking assembly 45 is released so that the rotary cylinder 3 is in a rotatable state, and the fitting plate 421 is in a slidable state and the tension spring 43 is in a stretchable state. Then, the reversing driving mechanism 5 is started to drive the two rotating drums 3 to synchronously and reversely rotate, the two film material flat clamping devices 4 keep synchronously rotating along with the respective rotating drums 3, and along with the progress of rotation, on one hand, the graphene heat insulation film is gradually twisted and wound, on the other hand, the matching plate 421 slides along the sliding guide plate 41 towards the direction away from the disc 31, the tension spring 43 gradually stretches, the distorted graphene heat insulation film is always in a tight state, the rotating is stopped after the rotating drums 3 reach the set detection number of turns, then the clamping of the graphene heat insulation film is released, the film surface condition of the observed graphene heat insulation film is taken down, whether the film material such as obvious wrinkles, stretching deformation and the like is damaged is observed, and therefore qualitative detection judgment is completed.
