Description

Technical Field

[0001] This utility model relates to the field of automotive interior technology, and in particular to a testing device for testing the softness and anti-adhesion of automotive leather. Background Technology

[0002] Automotive leather is used in leather products for automotive interiors and seats. With the rapid development of the automotive industry, the automotive leather market is also showing strong growth. Consequently, the number of testing and inspection items related to automotive leather materials is increasing.

[0003] The main problems currently existing in leather flexibility and anti-adhesion testing are insufficient standardization of testing methods, high equipment precision requirements, and complex influencing factors. Specific problems are as follows: 1. Insufficient standardization of testing methods: In anti-adhesion testing, different standards have different settings for parameters such as sample size and environmental conditions (e.g., temperature, humidity), leading to low comparability of test results. For example, adhesion testing requires samples to be bonded together before testing, but existing standards do not uniformly specify the specific operational details; sample sizes also vary. 2. When measuring anti-adhesion using a tensile testing machine after temperature storage, the small adhesion strength range of leather (2.5~10N / 10mm) means that even slight equipment deviations can lead to data distortion. 3. Anti-adhesion is not only related to coating materials but also involves processing technology (e.g., pressure plate temperature, pressure), environmental humidity, and other factors. For example, improper control of pressure plate parameters can lead to insufficient adhesion of the intermediate coating, thus affecting the test results. Utility Model Content

The base platform is shaped like a right trapezoid, the rectangular groove is located near the hypotenuse of the right trapezoid, and the square groove is located at the right-angle end of the right trapezoid.

[0006] As a preferred embodiment of this utility model, fixed magnets are pre-embedded on both sides of the rectangular and square grooves on the base platform. The fixed magnets are used to magnetically attract the scales, so that the spacing of the two scales in a set can be adjusted.

[0007] As a preferred embodiment of this invention, the minimum scale value of the ruler is 1 mm.

[0008] As a preferred embodiment of this invention, the beveled edge of the base platform is 45 degrees.

[0018] See Figure 1-4As shown in the figure, this embodiment provides a testing device for testing the softness and anti-adhesion properties of automotive leather, including: a base platform 1, a rectangular groove 2 and a square groove 3 formed on the top surface of the base platform 1, a scale 4 disposed on the top surface of the base platform 1 and located on both sides of the rectangular groove 2, a leather flexibility testing plate 5 located on the rectangular groove 2, and a leather anti-adhesion testing plate 6 located on the square groove 3. The base platform 1 is shaped like a right trapezoid, with the rectangular groove 2 located near the hypotenuse of the right trapezoid, and the square groove 3 located at the right-angle end of the right trapezoid. Fixed magnets are embedded on both sides of the rectangular groove 2 and the square groove 3 on the base platform 1. These magnets are used to magnetically attract the scale 4, allowing adjustment of the spacing between the two scales 4. The minimum scale value of the scale 4 is 1 mm. The hypotenuse of the base platform 1 is 45 degrees.

[0019] Working principle:

[0020] 1) Leather Flexibility Test: The dimensions of the first specimen 7 are set to be the same as the dimensions of the rectangular groove 2 on the upper surface of the base platform 1. The shorter side of the first specimen 7 is placed at the starting point A of the scale. A leather flexibility test plate 5 of the same size as the first specimen 7 is used to press the specimen down, and the specimen is slid forcefully towards the inclined plane. When the drooping side of the front end of the first specimen 7 just contacts the inclined plane, the scale reading at position B, where the other end of the first specimen 7 has moved, is immediately read and recorded. The main purpose of the rectangular groove 2 is to constrain the movement direction of the first specimen 7, ensuring that the first specimen 7 moves along the same axis without deviation, thus improving the accuracy of the test. Appropriate scale rulers 4 are placed on both sides of the rectangular groove 2, with a minimum scale value of 1 mm; a fixed steel ruler can be used to read the final test results.

[0021] 2) Leather anti-adhesion test: The vertical end of the base platform 1 is used for the anti-adhesion test. The size of the second sample 8 is set to be the same as the size of the square groove 3 on the upper surface of the base platform 1. Two second samples 8 with the required size are placed face to face and side to side. A leather anti-adhesion test pressure plate 6 is placed on top and aligned with three sides of the sample. The weight parameters of the leather anti-adhesion test pressure plate 6 must meet the test requirements. The sample is placed in an environmental chamber with a certain temperature and humidity. After the test time is reached, the sample is taken out. After removing the leather anti-adhesion test pressure plate 6, the two second samples 8 are removed without pressure and are moved away at a certain speed. The condition of the sample surface is observed.

[0022] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
