Shore hardness testing device and testing method

Abstract

The invention provides a shore hardness testing device and a shore hardness testing method and belongs to the technical field of material performance testing. The device comprises a test platform, a winding and unwinding unit, a hardness testing unit, a power unit, a first driving structure control unit, a second driving structure, a data acquisition unit and a control unit, wherein the top of which is provided with a test tabletop; the winding and unwinding unit is provided with a winding assembly and an unwinding assembly which are located on two sides of the test table board in the first preset direction respectively; the hardness testing unit comprises a testing frame and a shore durometer; and the shore durometer is arranged corresponding to the test table board and is movably connected with the test frame along the direction vertical to the test table board; the power unit comprises a first driving structure and a second driving structure; the first driving structure is used for driving the winding and unwinding unit to perform winding and unwinding actions; the second driving structure is used for driving the shore durometer to be close to the test table board for testing; the data acquisition unit is used for collecting test data of the shore durometer; and the control unit is in communication connection with the power unit. The method is carried out by adopting the device, continuous and automatic testing can be realized, testing efficiency is relatively high, and testing accuracy is relatively high.

Description

technical field [0001] The present application relates to the technical field of material performance testing, in particular, to a Shore hardness testing device and testing method. Background technique [0002] Hardness is one of the most important quality characteristics of EVA foam cushioning materials, and it is an important indicator to characterize its cushioning performance. In the prior art, when testing the hardness of the EVA foam cushioning material, a manual hand-held Shore durometer is usually pressed on the surface of the EVA foam cushioning material, and the reading is recorded within 1 second to record the hardness value. The test method is manually operated, and the test efficiency is low; and due to the different hand-held operations of the testers, there are large differences in the test, which reduces the authenticity of the hardness test. Contents of the invention [0003] The purpose of this application is to provide a Shore hardness testing device an...
