Description
Technical Field
The utility model belongs to the field of fabric detection, and particularly relates to a fabric compression elasticity tester.
Background
Elasticity and elastic recovery performance are important indexes for measuring the quality of elastic woven fabrics and knitted fabrics. There are two types of instruments currently used to test elasticity and elastic recovery: universal material testing machine and simple hanging weight device.
The test operation by using the universal material testing machine is very complicated, and the detection efficiency is very low. If the universal material testing machine has a cyclic testing function, although the testing precision is higher, the equipment price is high, and the economic benefit is very low. If the universal material testing machine does not have the cyclic testing function, the manual operation balance beam moves, so that a plurality of factors influencing the testing precision and accuracy exist, and the testing error is large. And because the moving speed of the cross beam is limited, the universal material testing machine cannot test the elasticity and the elongation performance of the knitted fabric with higher elasticity.
And the simple weight-hanging device is used for testing the elasticity, the elongation and the recovery of the fabric, the whole process is manually operated, the time interval of the circular weight hanging is difficult to accurately control, and the problems of poor testing precision and poor parallelism exist.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to solve the defects of the prior art, the utility model provides a fabric compression elasticity tester.
The technical scheme is as follows: the utility model provides a fabric compression elasticity tester, includes tester surface fabric platform, tester surface fabric bench side fixed mounting have the lifter, the bottom fixed mounting of lifter have the test code, the test code can be two kinds for square test code or hemisphere test code, the lifter be connected with displacement sensor, the lifting change of lifter is measured by displacement sensor accuracy, the built-in power value sensor of test code, the test code atress size is measured by built-in power value sensor, power value sensor in be equipped with a plurality of piezo-resistor, piezo-resistor evenly distributed, be 6/cm2And arranging, wherein the surface of the test code (2) is also covered with a layer of polyurethane film.
As an optimization: place the elastic object on the tester surface material bench, then the test code descends along with the lifter, descends along with the test code, and the test code is pressed and is put on the elastic object, and under certain pressure, the phenomenon that the position descends can take place for the test code, and displacement sensor and force value sensor can send the position of test code, atress information for the host computer, carry out data analysis, form the judgement to the elastic object.
