Background
The film is a thin and soft transparent sheet, and is generally made of plastic, adhesive, rubber or other materials. After the film is manufactured, the film needs to be detected to detect whether each index of the film is qualified or not, wherein one detection index is the tensile strength. Wherein the tensile strength refers to the load bearing capacity of the film in the transverse direction or the longitudinal direction, and the load bearing capacity is shown by stretching the film at a certain test speed until the film is broken through a telescopic clamp. When the tensile strength of the film is detected, the two sides of the film need to be fixed through a clamp. The conventional clip generally includes only an upper clip and a lower clip, and when fixing the film, the film is placed between the upper clip and the lower clip, and then the upper clip and the lower clip are fixed. However, because the thickness of the film is very thin, the existing clamp has the situation that the film is not clamped tightly when the film is fixed, namely, the film and the clamp move relatively in the detection process, even the film is separated from the clamp, and the detection result is further influenced. And the existing film detection process has single detection result, cannot fully reflect the quality of a film product, and has inaccurate measurement result.

When the quality of the finished film is detected, the motor 11 is started, the motor 11 drives the driving wheel 24 to rotate, and the driven wheel 26 is driven to rotate through the transmission belt 25. At this time, the stopper is rotated to abut against the nut 27 and restrict the nut 27 from rotating. The screw 28 rotates with the driven roller 26 and is in threaded fit with the nut 27, and at this time, the driven roller 26 moves axially under the action of the screw 28, that is, the transmission ratio of the driving wheel 24 to the driven roller 26 changes, that is, the rotating speed of the first gear 12 changes, so that the moving speed of the moving seat 23 changes, that is, the pulling force on the film also changes, and the quality of the film at different pulling forces, especially when the film is suddenly subjected to a large force, can be detected. The tension wheel 31 and the elastic telescopic rod 30 can ensure the transmission between the driving wheel 24 and the driven roller 26. When the moving speed of the moving seat 23 is not required to be changed, the stopper is rotated so as not to abut against the nut 27.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
