Demand Law of Fabric Weight on the Airflow Velocity of a Gas-Assisted Model

Abstract

This research takes as its basis the engineering requirement that the cloth conveyed by a cloth-feeding mechanism moves forward for a certain distance in a balanced and stable manner; therefore, a scheme for the air-assisted conveyance of fabric is designed. The traditional fabric-conveying mechanism occupies a large space, consumes a lot of energy, and the conveying is unstable, As a new type of conveying method, the technology of using a gas-assisted device to convey fabric has emerged rapidly due to its extensive application range, and the fact that it produces no pollution and zero emissions. By establishing the mathematical model of the balance between the upper and lower surfaces of conveyed fabric, the Creo flow analysis module is used to simulate and analyze the surface pressure distribution of conveyed fabric. The purpose is to analyze the influence of fabrics with different weights on the airflow velocity in the pipeline when the fabric is conveyed in a balanced state and to determine the layout scheme of the air supply pipeline, as well as the configuration law of the airflow velocity in the pipeline. The research results demonstrate that the constructed air-assisted conveying mechanism model is able to realize the smooth lifting and forward conveying of different fabrics, The fabric with a density of 60 g/cm² has been smoothly suspended and transported forward for 200 mm, and the regularity can be obtained by comparing the weight of 30–80 g/cm² different fabrics. As the weight of the fabric increases, the flow rate in each row of pipes and the total flow rate of the air compressor also show an upward trend, forming a certain linear law, providing a reference for the development of the next-generation home-textile kit, which has three-sided automatic sewing and an integrated cutting device.
