AI Technical Summary

Technical Problem

Existing plastic film tensile testing devices are prone to causing the plastic film to tear or loosen at the fastening structure, and the testing method is limited, making it impossible to effectively evaluate the diverse tensile properties of plastic films.

Method used

A plastic film tensile testing instrument was designed, which uses a winding device and a pushing device to perform tensile testing through both winding and pushing methods. The plastic film is fastened by the winding assembly and the transmission assembly, and the tensile performance is detected by the pressure sensor.

Benefits of technology

It improves the reliability of plastic film fastening, prevents tearing or loosening, and allows for diverse testing of the tensile properties of plastic film, including winding stretching and push-forward stretching, providing a more comprehensive performance evaluation.

Abstract

This invention relates to the field of material tensile testing, specifically to a plastic film tensile testing instrument. It includes a base, a pressure sensor, a forward pushing device, a winding device, and a limiting mechanism. The forward pushing device includes a movable frame, a push platform hinged to the top front of the movable frame, and a telescopic device mounted on the base and driving the movable frame to move horizontally. The winding device includes a mounting frame mounted on the base, a winding assembly rotated vertically on the mounting frame, a transmission assembly connected to the winding assembly, and a movable plate mounted on the transmission assembly. The pressure sensor is mounted on the movable plate. The limiting mechanism includes a sliding column, a movable platform for horizontal sliding of the sliding column, and an adjusting assembly for adjusting the position of the movable platform. This invention can first secure the ends of the plastic film and then wind it, improving the reliability of the secure connection and preventing tearing or loosening of the plastic film at the secure point. It can also perform winding tensile and forward pushing tensile tests on the plastic film, providing diverse testing methods.
