Description

Technical Field

[0001] This utility model relates to the field of thin film tension detection technology, specifically a thin film tension detection sensor. Background Technology

[0002] Thin film materials are widely used in many industrial production and manufacturing processes, such as packaging, printing, electronics, and textiles. During production, processing, and use, the tension and stability of the film have a crucial impact on product quality and production efficiency. Taking the packaging industry as an example, in processes such as film slitting, lamination, and printing, excessive film tension can lead to stretching deformation or even breakage, affecting product integrity and appearance quality; conversely, insufficient tension can cause wrinkles, loosening, and other defects, resulting in misregistration and poor lamination. In the electronics industry, as a carrier or insulating material for electronic components, unstable film tension can affect the performance and reliability of these components.

[0003] To ensure the quality of thin film products and the smooth operation of the production process, a thin film tension detection sensor is proposed here. Utility Model Content

[0008] Furthermore, each of the two clamping seats has two auxiliary grooves on its surface, and each of the four auxiliary grooves has a first fixing hole inside. Each of the two elastic connectors has two second fixing holes at both ends on its inner side, and the four first fixing holes are respectively set to correspond to the four second fixing holes.
