[0028] Example 1

[0029] Please see the attached Figure 1-4 The purpose of this embodiment is to provide an electric uniform speed device for testing the bending stiffness of textiles, comprising: a supporting platform 1, a driving assembly 2, a steel ruler 3 and a rubber plate 4; the table top 13 of the platform body 11 of the supporting platform 1 is arranged horizontally, and a baffle 12 is provided on one side of the table top 13. The inclined surface 14 of the platform body 11 intersects with the table top 13, and the angle between the inclined surface 14 and the table top 13 is 41.5°. A plurality of guide wheels 15 are provided on the table top 13; the driving assembly 2 is arranged on the side of the inclined surface 14 away from the platform body 11, and the driving assembly 2 is used to drive the steel ruler 3 to translate in the direction close to the inclined surface 14. A plurality of supporting legs 16 are provided at the bottom of the platform body 11 to ensure the stability of the platform body 11. Compared with the existing technology, the way of moving the steel ruler 3 forward is changed from manual pushing to pushing by the driving assembly 2, which saves manpower and is easier to control.

[0030] The drive assembly 2 comprises multiple support columns 21, the top ends of which are connected to the bottom surface of a support plate 22. A telescopic drive member 23 is fixedly mounted on the top surface of the support plate 22. In this embodiment, the telescopic drive member 23 is an electric telescopic cylinder, whose extended rod drives the steel ruler 3. It should be noted that the multiple support columns 21 can be electric, hydraulic, or pneumatic cylinders, allowing for fine-tuning of the height of the telescopic drive member 23.

[0031] Specifically, the surface of the steel ruler 3 is provided with scale lines 31 extending from one end to the other. The axes of the multiple guide wheels 15 are aligned and arranged parallel to the baffle 12. The presence of multiple guide wheels 15 on the table 13 ensures that the steel ruler 3 does not deviate during forward movement, thereby improving the relative accuracy of measurement.

[0032] Example 2

[0033] Please see the attached Figure 1-4 The purpose of this embodiment is to provide an electric uniform speed device for testing the bending stiffness of textiles, comprising: a supporting platform 1, a driving assembly 2, a steel ruler 3 and a rubber plate 4; the table top 13 of the platform body 11 of the supporting platform 1 is arranged horizontally, and a baffle 12 is provided on one side of the table top 13. The inclined surface 14 of the platform body 11 intersects with the table top 13, and the angle between the inclined surface 14 and the table top 13 is 41.5°. A plurality of guide wheels 15 are provided on the table top 13; the driving assembly 2 is arranged on the side of the inclined surface 14 away from the platform body 11, and the driving assembly 2 is used to drive the steel ruler 3 to translate in the direction close to the inclined surface 14. A plurality of supporting legs 16 are provided at the bottom of the platform body 11 to ensure the stability of the platform body 11. Compared with the existing technology, the way of moving the steel ruler 3 forward is changed from manual pushing to pushing by the driving assembly 2, which saves manpower and is easier to control.

[0034] The drive assembly 2 comprises multiple support columns 21, the top ends of which are connected to the bottom surface of a support plate 22. A telescopic drive member 23 is fixedly mounted on the top surface of the support plate 22. In this embodiment, the telescopic drive member 23 is a hydraulic cylinder or a pneumatic cylinder, and the extended rod of the telescopic drive member 23 drives the steel ruler 3. It should be noted that the multiple support columns 21 are electric, hydraulic, or pneumatic cylinders, allowing for fine-tuning of the height of the telescopic drive member 23.

[0035] Specifically, the surface of the steel ruler 3 is provided with scale lines 31, which extend from one end of the steel ruler 3 to the other. The axes of the multiple guide wheels 15 are located on the same straight line, and the multiple guide wheels 15 are arranged in a direction parallel to the baffle 12. Each guide wheel 15 can move along the width of the table 13, which facilitates adjustment of the gap between the guide wheel 15 and the steel ruler 3. In theory, the guide wheel 15 is locked when it just contacts the steel ruler 3. The locking method adopts the method of the prior art and will not be repeated here. The multiple guide wheels 15 provided on the table 13 can ensure that the steel ruler 3 does not deviate when moving forward, thereby improving the relative accuracy of the measurement.

[0036] The measuring devices of the two aforementioned embodiments, when measuring the bending stiffness of a textile 5, employ the following specific methods: The textile 5 is placed on the table surface 13 of the platform body 11, and the rubber sheet 4 and steel ruler 3 are placed sequentially above the textile 5. The front ends of the textile 5, the rubber sheet 4, and the steel ruler 3 are aligned, with the front ends of the rubber sheet 4 and the steel ruler 3 aligned so that they coincide with the intersection of the table surface 13 and the inclined surface 14. The telescopic drive member 23 is then adjusted so that its extended rod drives the steel ruler 3 forward until the bent front end of the textile 5, under the action of gravity, contacts the inclined surface 14, and the drive stops. It should be noted that the friction between the rubber sheet 4 and the textile 5, and the friction between the rubber sheet 4 and the steel ruler 3, are both greater than the friction between the textile 5 and the table surface 13, ensuring that the textile 5, rubber sheet 4, and steel ruler 3 can move forward synchronously.

[0037] Then calculate the bending stiffness G according to the formula. The specific calculation method is as follows:

[0038] G=m×C 3 ×10 -3

[0039] G represents the bending stiffness per unit width, in millinewtons centimeters;

[0040] m represents the mass per unit area of textiles, in grams per square meter;

[0041] C represents the average bending length of the textile in centimeters;

[0042] Here, m can be obtained by a measuring instrument, and C is half of the extended length, wherein the extended length is the extended length of the textile 5 when the steel ruler 3 extends and bends to contact the inclined surface 14, that is, the length of the steel ruler 3 extending from the table surface 13.

[0043] Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model should be included in the scope of protection of this utility model.
