Leather performance index testing instrument

Abstract

The invention relates to a leather performance index testing instrument. The leather performance index testing instrument comprises a stepping motor, a speed reducer, a translation block, a lead screw, a shaft coupler, a clamping device, a testing head, a worktable, a displacement sensor and a pressure sensor, wherein the clamping device is fixedly connected on a bottom plate of a rack by the worktable; the testing head is arranged on the clamping device; the pressure sensor is arranged at the upper end of the testing head and is arranged on the translation block by a pressure sensor mounting table; the translation block is in transmission connection with a stepping motor fixed at the upper end of the rack by the lead screw and the shaft coupler; the side of the translation block is fixedly connected with a reading head; the displacement sensor corresponding to the reading head is arranged on the side surface of the rack; and the stepping motor, the pressure sensor, the displacement sensor and the reading head are connected with a control system. The leather performance index testing instrument has a simple structure and is flexible to use; the reliability of a leather performance index test is guaranteed, an on-line test of the leather performance index is realized, and the requirements on a specific test also can be met, the high-efficiency requireemnts on industrial production furtehr can be met and requireemnts of the industrial production can be met.

Description

technical field [0001] The invention relates to a leather performance index tester, in particular to a computer-based automatic tester capable of measuring various leather performance indexes. Background technique [0002] Leather performance index is an important index reflecting the quality of leather. At present, the evaluation of leather quality in actual production mainly adopts a relatively traditional method, that is, using experienced inspectors to identify leather quality through senses such as touch. Although this method is convenient, it is too subjective, and there are certain differences in the personal experience of the inspectors, and the evaluation results are easily affected by factors such as working environment and mood. [0003] At present, the theoretical research of the leather performance index tester has a certain foundation, but the prototype design and manufacture of the leather performance index tester are still in the initial stage. For ex...

Although this method is convenient, it is too subjective, and there are certain differences in the personal experience of the inspectors. At the same time, the evaluation results are easily affected by factors such as working environment and mood.

[0003] At present, the theoretical research on the leather performance index tester has a certain foundation, but the prototype design and manufacture of the leather performance index tester are still in its infancy.

For example, the leather softness and fullness measurement and grading device designed by Professor Zhang Xiaolei of Shaanxi University of Science and Technology cannot fully meet the requirements of leather performance index testing.
