Multi-performance testing device and method for high polymer material

Abstract

The invention relates to a multi-performance testing device for high polymer materials, wherein the device comprises a rack, a fixed limiting mechanism and a movable limiting mechanism; one end of the top of the rack is fixedly provided with the fixed limiting mechanism, the other end of the top of the rack is slidably provided with the movable limiting mechanism, and the movable limiting mechanism and the fixed limiting mechanism have the same structure; a mounting arm is mounted in the middle of the side wall of the rack, and a camera is mounted on the side wall of the mounting arm; and when a pressing plate moves downwards to a second rolling wheel on a wheel seat to drive a movable rod to compress a second spring in an adjusting groove, the high polymer material is limited between a first rolling wheel and the second rolling wheel through elastic deformation of the second spring, at the moment, a motor on a supporting plate works to drive a threaded rod to rotate, two sliding columns which are in threaded connection and located in the middle of the threaded rod are driven to move towards the two ends of the sliding groove respectively, the high polymer material is stretched, wrinkles of the high polymer material are avoided, and the accuracy of test data is guaranteed.

Description

technical field [0001] The invention relates to the technical field of polymer material detection, in particular to a multiple performance testing device and method for polymer materials. Background technique [0002] Polymer materials are materials based on polymer compounds; polymer materials are materials composed of compounds with relatively high molecular weights, including rubber, plastics, fibers, coatings, adhesives, and polymer-based composite materials. form. [0003] When testing the tensile elastic modulus, tensile strength and elongation at break of polymer materials such as fibers and packaging bags, it is necessary to fix the ends of the polymer materials. The existing fixing methods have certain limitations. ; At the same time, during the detection process, it is necessary to ensure that the polymer material is flat, otherwise it is easy to cause errors in the test results.
