Description

Technical Field

[0001] This utility model relates to the field of leather testing technology, specifically a leather abrasion resistance testing device. Background Technology

[0002] In the field of leather product manufacturing and quality inspection, abrasion resistance is a key indicator for measuring its durability. Existing leather abrasion resistance testing devices mostly adopt a single-point testing structure, that is, a single abrasive is driven by a drive mechanism to rub a leather sample back and forth, and the abrasion resistance is evaluated by observing the degree of wear on the sample surface.

[0003] However, the traditional testing methods mentioned above have obvious limitations. Each test can only be conducted on one type of leather or abrasive, and parallel comparative tests cannot be performed. If it is necessary to compare the abrasion resistance differences of different leather or abrasive materials, two separate tests must be conducted. However, since there is a time interval between the two tests, it is difficult to keep the external conditions such as ambient temperature, humidity, and drive mechanism status completely consistent. This introduces additional variables, which may lead to inaccurate comparison results, reduced reliability, and affect the scientific nature and efficiency of the test data. Utility Model Content
