Description

Technical Field

[0001] This utility model relates to the field of tenter frame technology, specifically to a flat edge blowing and stretching device for a tenter frame. Background Technology

[0002] In the textile printing and dyeing industry, the tenter frame is a key piece of equipment for finishing fabrics. Its function is to make the fabric reach the predetermined width and dimensional stability through mechanical stretching and heat setting, while improving the hand feel and appearance quality of the fabric.

[0003] During the production process of a tenter frame, when the fabric enters the equipment through the overfeed guide roller, the problem of edge smoothness is particularly prominent due to the special nature of the overfeed process and the characteristics of the fabric itself. By controlling the fabric feeding speed to be higher than the operating speed of the equipment, the overfeed guide roller can effectively reduce the fabric tension, but it can also cause edge wrinkles and curling in the relaxed state of the fabric. Specifically, when the fabric runs on the surface of the guide roller, the edges are easily affected by roller friction, airflow disturbance and mechanical vibration due to the lack of uniform tension support in the central area, forming wavy undulations or local folds. This problem of uneven edges is particularly obvious in the processing of chemical fiber blends, elastic fabrics and ultra-thin fabrics. Although the existing mechanical pressure roller leveling method can partially improve wrinkles, it will leave indentations on the fabric surface, which is especially unsuitable for sensitive materials such as silk and lace, and cannot meet the current requirements.
