Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and more specifically, it relates to a zipper head torque testing device. Background Technology

[0002] In the zipper manufacturing industry, the quality of the zipper pull plays a crucial role in the overall performance of the zipper. Among the key indicators of zipper pull quality is the torque between the zipper pull tab and the zipper pull body. If the torque is too low, the zipper pull tab will easily rotate during daily use, leading to inconvenience in opening and closing the zipper or even accidental slippage. Conversely, excessive torque will cause operational difficulties for the user, reducing the user experience.

[0003] Currently, traditional methods for testing zipper pull torque have many shortcomings. Some factories rely on subjective human judgment, depending on experience to feel the resistance of the zipper pull tab. This method lacks precision, and the judgment standards of different operators vary, making it impossible to guarantee consistent product quality. Other companies use simple tools for testing, but these tools are limited in function and lack versatility, making it difficult to adapt to the testing needs of different specifications and types of zipper pulls. Furthermore, they cannot accurately measure and record torque values ​​during testing, hindering improvements in production processes and quality control. Therefore, there is an urgent need for a device that can accurately, efficiently, and universally test zipper pull torque. Utility Model Content
