Needle tester and needle testing method

Abstract

The invention discloses a needle tester and a needle testing method, and relate to the technical field of needle testing. The needle tester comprise a support, and further comprise a fixing table anda rotating assembly, wherein the fixing table is arranged on a support and used for fixing a tested needle a; and the rotating assembly is arranged on the support, and the rotating assembly provides swinging arc force for the tested needle a when rotating. The beneficial effects of the invention are that a professional tester is designed, accurate measurement can be carried out on the tested needle, the acting force for testing the needle is enabled to be always stable in position, and the force simulation is more accurate; and the tester has multiple functions and can be used for conducting rebound resilience testing, bending fatigue testing, bending-resistant angle testing and fracture testing.

Description

technical field [0001] The invention relates to the technical field of needle testing, in particular to a needle tester and a testing method using the tester. Background technique [0002] The technology of producing non-woven fabrics with needles has a history of more than 100 years. With the development of science and technology, various new types of needles continue to emerge. However, for the quality and physical performance testing of needles, in addition to using traditional hardness testers to measure hardness, outer micrometers and calipers to measure dimensions, and metallographic microscopes to detect metallographic structures, there are no other special physical performance testing instruments and equipment. The comprehensive evaluation of the physical and physical properties of various needles has led to product standards, testing indicators and methods, but no professional testing instruments and means have existed for a long time, thus causing the following pro...

Problems solved by technology

However, for the quality and physical performance testing of needles, in addition to using traditional hardness testers to measure hardness, outer micrometers and calipers to measure dimensions, and metallographic microscopes to detect metallographic structures, there are no other special physical performance testing instruments and equipment. The comprehensive evaluation of the physical and physical properties of various needles has led to product standards, testing indicators and methods, but no professional testing instruments and means have existed for a long time, thus causing the following problems:

[0003] 1. The user cannot judge the quality of the needle without actual use (such as wear life, fracture resistance and resilience, temperature rise caused by friction with the cloth surface, etc.)

[0004] 2. When the user does not know the physical performance indicators of each brand and model of needle, it is impossible to choose the appropriate needle specification model and brand according to the final requirements of the product process

[0005] 3. In the absence of complete testing methods and testing instruments, it is difficult for needle manufacturers to ensure the pass rate of products and further improve product quality

[0006] 4. Professionals in research institutes, colleges and R&D centers who want to use new materials to develop non-woven products with new functions cannot accurately obtain the force of each needle or the entire needle when piercing the fiber web and the impact on the fiber. net effect

[0007] 5. Needle users dare not fully utilize the functions and efficiency of the needles they use
