Abstract
Description
Technical Field
[0001] The utility model relates to the field of shadow force measurement, and in particular to a pulling tester for high blocking conformal films. Background Art
[0002] High barrier film is a multi-layer film made by extruding a material with strong gas barrier properties and a polyolefin with strong heat-sealing and moisture barrier properties. The film is wound on a film cylinder for processing. During the processing, the tensile force of the film needs to be tested in order to determine the bearing pressure of the finished film.
[0003] The patent specification with announcement number CN210893939U discloses a tester for detecting the tensile force of plastic film, wherein a group of limit blocks are symmetrically welded at the inner bottom of the main body of the device, a slide groove is provided at the bottom of the main body of the device and between the two limit blocks, a clamp is slidably connected in the slide groove, an outer cylinder is provided at the inner top of the main body of the device, a through hole is provided on the outer cylinder, and a scale is etched on the outer wall of the outer cylinder near the through hole, a clamp is provided in the outer cylinder, a turntable is provided on one side of the upper end of the main body of the device, and a crank is welded on the turntable, and the clamp includes a fixed block, and connecting rods are connected to the lower two sides of the fixed block. The device of this application is small, simple to operate, and has low manufacturing cost. It is suitable for small enterprises and scientific experiments. The device stretches the plastic film to observe the stretching distance, thereby calculating the tensile strength of the film.
[0004] The above technical solution requires that the two ends of the membrane be fixed on the upper and lower clamping devices, but in actual operation, if wrinkles appear on the surface of the membrane, it will affect the actual pulling displacement. Usually, the staff needs to flatten the membrane with both hands, which takes a lot of time and is cumbersome and inconvenient. To this end, we proposed a pulling tester for high blocking conformal membranes. Utility Model Content
