Bending elasticity tester and testing method for palm fibers

Abstract

The invention relates to a bending elasticity tester and testing method for palm fibers. The bending elasticity tester structurally comprises a base, a micrometer, a palm fiber bending and fixing clip and an electronic scale, wherein the electronic scale is placed on the base, the palm fiber bending and fixing clip is arranged above the electronic scale, the micrometer is fixedly arranged on a movable cross rod, and the movable cross rod penetrates through two vertical round rods fixedly arranged on the base to move up and down and are rotatably fixed through screws. The tester has the advantages that 1) contact between palm fiber bending deformation and stress is established through displacement of the micrometer and the numerical value of the electronic scale, and the whole tester is skillfully established through relatively simple equipment which is low in cost; 2) multiple devices of the tester can be movably retracted, and the fixed cross rod of the micrometer can be adjusted up and down so as to test fibers with different curvatures, and the palm fiber bending and fixing clip further can be adjusted in length left and right so as to realize different curvatures of the fibers; and 3) the two main measuring parts, namely the micrometer and the electronic scale, are electronically read, so that the micrometer and the electronic scale are relatively precise.

Description

technical field [0001] The invention relates to a tester and a testing method for the bending elasticity of palm fiber on a palm mattress, and belongs to the technical field of testing the bending elasticity of palm fiber. Background technique [0002] At present, there is no relevant research report on the elastic force in the vertical direction when the palm fiber is bent. The existing device for testing the elasticity of brown fibers basically follows the testing method of textile fibers, breaking them with a tensile machine to test the maximum tensile modulus, but brown fibers are different from textile fibers, especially for brown mattresses. The fiber is laminated and bent to produce elasticity, and stretching elasticity does not directly contribute to the elasticity of the mattress. The structural principle of the instrument is to push the bent brown fiber to produce deformation through a micrometer to generate elasticity, which reacts on the electronic scale to displ...

AI Technical Summary

Problems solved by technology

The defects of the instrument are: 1) The bent brown fiber is deformed by external force. In theory, the deformation at the maximum bending point should be measured. Since the brown fiber is a natural material, it is easy to slip or twist during deformation, which is easy to cause a sudden change in force.

2) Micrometers and electronic scales need to be read manually, which is prone to errors
