Description

Technical field [0001] The invention involves the field of packaging membrane performance detection technology, which is specifically for a packaging film stretching strength performance detection device and detection method. Background technique [0002] The stretching strength performance of the packaging membrane is one of the important factors that determine the quality of the packaging film. Therefore, in the process of the production of the packaging film, the packaging film sample (hereinafter referred to as sample) needs to be selected for stretch strength performance detection. First fix the sample on the fixture of the tensile strength detection device, then start the stretching strength detection device, stretch the sample through the fixture, and detect the sample stretch strength during the stretching process. [0003] The existing tensile strength detection device is detected during the sample detection. Because the perspective of the test personnel is easily observ...

Problems solved by technology

[0003] In the process of testing the sample, the existing tensile strength testing device cannot fully observe the placement of the sample because the viewing angle of the testing personnel is easily blocked by the fixture and other parts on the device, thereby easily reducing the accuracy of sample placement and The convenience of sample placement will correspondingly reduce the accuracy of sample detection, affect the company's understanding of the quality of the coating, and in severe cases will cause huge economic losses to the company

[0004] In view of the above problems, some existing solutions are to simplify the structure of the fixture on the tensile strength testing device and the structure of the parts near the fixture, but the problem with this measure is that it is difficult to control the sample clamping force, and it is easy to use it in the test. The sample falls off during the process, which will affect the progress of sample testing and the efficiency of testing
