Description

Technical Field

[0001] The utility model relates to the technical field of zipper production, in particular to a durability detection mechanism for zipper manufacturing. Background Art

[0002] The durability testing mechanism for zipper manufacturing is a device used to test the durability and life of zippers. During the test, the zipper is repeatedly pulled and pulled back to simulate the zipper operation in daily use. The testing machine usually records the number of times the zipper is pulled and the damage of the zipper to evaluate the durability and life of the zipper. Through these tests, it can be determined whether the zipper can withstand long-term use and whether it is easy to break or damage during use. The life test of the zipper is to ensure the quality and durability of the zipper to meet the needs and usage requirements of consumers. Such tests can help manufacturers improve product design and production processes and improve product quality and reliability.

[0003] During the test, the zipper is fixed and a certain lateral force acts on the fabric tape, simulating the state of the zipper being sewn on a garment and worn. After a certain number of opening and closing movements, the zipper is observed to see if there is any form of damage. If there is no damage, it means that the zipper can withstand a certain number of uses. However, the existing testing mechanism is not convenient for fixing the zipper head on the device, and the fixed position cannot be adjusted according to the length of the zipper. Therefore, we proposed a durability testing mechanism for zipper manufacturing. Utility Model Content
