AI Technical Summary

Technical Problem

Existing PE stretch film testing devices cannot quantitatively detect its tensile properties, making the evaluation process inconvenient.

Method used

Two sets of film end clamps are used to hold the wound film, and a spring tension mechanism accumulates potential energy to prevent the clamps from sliding. Combined with a maximum tension measuring mechanism to record the sliding distance of the clamps, the tensile strength is quantitatively tested.

Benefits of technology

This technology enables quantitative testing of the tensile strength of stretch film, improving testing efficiency and accuracy.

Abstract

The utility model discloses a high-elasticity PE (polyethylene) wrapping film production detection device, which belongs to the technical field of PE wrapping film detection devices and comprises a device support, a film end clamp, a spring tension mechanism and a maximum tension metering mechanism. When the spring tension mechanism moves, the maximum tension metering mechanism is synchronously driven to move. According to the technical scheme, during detection, the film end clamp on one side is pulled, the film end clamp on the other side can be driven to slide under the force transmission effect of the winding film, at the moment, the spring tension mechanism can accumulate elastic potential and apply reverse tension, and the maximum tension metering mechanism can record the maximum stroke of the spring tension mechanism; the detection device is simple in structure, has the characteristic of quantitative tensile strength, and can be used for conveniently and efficiently detecting and evaluating.
