Description

Technical Field

[0001] The utility model belongs to the technical field of testing instruments and equipment, and particularly relates to a sanding belt anti-debonding tensile force testing device. Background Art

[0002] Tensile testing machines are widely used in various physical and mechanical property tests of materials such as rubber, plastic sheets, pipes, profiles, plastic films, wires and cables, waterproof coils and metal wires. Tensile testing machines generally include a base, a lifting mechanism, a tensile gauge, an upper fixture and a lower fixture. The lifting mechanism is located on the base, the tensile gauge is located at the driving end of the lifting mechanism, the upper fixture is located at the sensing end of the tensile gauge, and the lower fixture is located on the base and below the tensile gauge.

[0003] However, the imperfect structural design of the upper and lower clamps in the existing tensile testing machines makes the clamping force unstable when testing thin sheet objects, so the measured tensile force is unstable, resulting in inaccurate test results; moreover, the existing upper clamp is in hard contact with the tensile gauge, and when testing the adhesion between thin sheets, it will not adapt to the change in the direction of the force, so that the force direction of the tensile sensor is inconsistent with the force direction of the object to be tested, further increasing the error of the test result. Utility Model Content

[0004] The utility model provides a sanding belt anti-debonding tensile test device, which is used to solve the technical problems in the prior art such as the unstable tensile force obtained when testing thin sheet-like objects. It only relies on experience and feeling without data support, which brings a lot of troubles to the overall quality improvement. In order to accurately capture the glue bonding strength data, a special tool is invented.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: a sand belt anti-debonding tensile test device, which is used to test the anti-debonding bonding strength of the sand belt, the sand belt includes a first section and a second section that are glued together, including:
