Description

Technical Field

[0001] The utility model belongs to the technical field of film tensile testing, in particular to a film strength tensile testing device. Background Art

[0002] Film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials, the tensile tester can be used to test the physical and mechanical properties of the film and provide data support for the production and research and development of the film. During the experiment, the film sample to be tested can be clamped between the upper and lower clamps of the tensile tester, and then the upper clamp is driven by the linear drive mechanism of the tensile tester to move the stretched film sample.

[0003] The control system of the tensile tester can detect the tensile force exerted on the film sample in real time through the set tensile sensor and other detection equipment until the film sample breaks. The existing film tensile test device needs to clamp and fix both ends of the film by a clamp, and bolt locking mechanisms are provided on both sides of the clamp. When fixing one end of the film, it is necessary to adjust two sets of bolt locking mechanisms at the same time. Although the film can be fixed, it takes a long time to fix and clamp the film. At the same time, it is difficult to clamp and fix the film in the center position of the clamp, which leads to deviations when testing the film, resulting in reduced practicality of the equipment. Utility Model Content

[0009] The adjustment mechanism is arranged inside the clamping base and is used to adjust the position of the clamping plate.

[0010] Furthermore, the adjustment mechanism includes a driving gear, a connecting screw, a limiting sleeve and a connecting rod. The driving gear is rotatably connected to the internal central position of the clamping base, the connecting screw is arranged on the upper end surface of the driving gear, the limiting sleeve is sleeved on the outer surface of the connecting screw, and the limiting sleeve can be slid up and down along the inside of the connecting screw for adjustment.

[0011] Furthermore, convex parts are arranged on both sides of the clamping plate, and the convex parts can be embedded in the inner side of the clamping panel and the clamping plate can be slidably adjusted left and right.
