Description

Technical Field

[0001] This utility model relates to the field of tension adjustment technology, specifically a tension adjustment device. Background Technology

[0002] Fabric conveying refers to the process of transporting fabric from one place to another through mechanical equipment or systems. It is commonly used in the production process of industries such as textiles, clothing, footwear, and home furnishings. Its core function is to improve production efficiency, reduce manual handling, and ensure the continuity of material flow. However, during the transmission process, materials may become loose or over-tensioned due to changes in length, mechanical vibration, or external forces, leading to unstable transmission, material wrinkles, or even breakage. In traditional fabric conveying devices, the tension rollers are mostly fixed in position, making it inconvenient to adjust the tension according to the needs of the fabric, which can easily lead to unstable fabric conveying.
