Description

Plastic film tensile testing machine

Technical Field

The utility model relates to the technical field of film tension test, in particular to a plastic film tension tester.

Background

As is well known, a film tensile tester is mainly used for tensile test of a film, and the tensile test refers to a test method for measuring the characteristics of a material under the condition that the material is subjected to axial tensile load, and the elastic limit, elongation, elastic modulus, proportion limit, area reduction amount, tensile strength, yield point, yield strength and other tensile performance indexes of the material can be determined by using data measured by the tensile test.

The existing film tensile testing machine is fixed through the both ends of anchor clamps to plastic film, when tensile back to plastic film, plastic film can take place deformation, and plastic film can be inseparable attached at the anchor clamps surface, when taking off plastic film after the test is accomplished, directly upwards or downwards pulling plastic film hardly takes off plastic film, needs to tear plastic film along the anchor clamps surface, causes the speed of taking off plastic film too slowly, influences plastic film's test efficiency.
