Description

Technical Field

[0002] With the widespread application of plastic products in modern industry and daily life, plastic films are widely used due to their lightness, durability and high cost-effectiveness. Plastic films are widely used in packaging, agricultural covering, health care, and electronic manufacturing. In these applications, the tear resistance of the film has become one of the key parameters to ensure product quality and performance. The tear resistance not only affects the service life and reliability of the product, but is also directly related to the safety and user experience of the user. However, the traditional evaluation methods of the tear resistance of plastic films have multiple limitations. First, traditional methods often rely on manual operation and subjective judgment, which is not only inefficient, but also has poor accuracy and repeatability of the results. Secondly, some detection methods may destroy the integrity of the sample and cannot achieve non-destructive testing. In addition, with the continuous development of plastic film technology, the demand for testing tear resistance is also increasing. Traditional detection devices and methods can no longer meet current detection requirements. Utility Model Content

[0021] Working principle: When it is necessary to test the tear resistance of the plastic film, the operator places the film sample to be tested on the platform 2 and fixes it below the detection pressing device 3. By controlling the working state of the telescopic cylinder 33, the pressing force applied by the pressure head 36 connected to the cover plate 32 to the film sample is adjusted. This adjustment can ensure that the applied pressure is within an appropriate range to obtain accurate test results. When the pressing force reaches the set value, the tear test is started. The force applied by the pressure head 36 causes the film sample to tear under certain tensile conditions. The testing instrument records data such as the tear strength and tear distance of the film to evaluate its tear resistance. The function of the winding device 4 is to automatically control the winding and unfolding of the film before and after the test.
