Active continuous let-off system for carbon fiber weaving

Abstract

The invention provides an active continuous warp feeding system for carbon fiber weaving. The active continuous warp feeding system comprises a frame, a first reed combination, an upper yarn guide roller combination, a rubber guide roller, a first stainless steel yarn guide roller, a second reed combination, a second stainless steel yarn guide roller, a tension balance device, a third stainless steel yarn guide roller and a fourth stainless steel yarn guide roller. A motor drives the rubber guide roller to rotate at a constant speed, a certain quantity of fibers are fed into the tension balance device due to the friction force between the rubber guide roller and the fibers, the warp tension is finely adjusted through lubrication of the vertical positions of the yarn guide rollers, and it is guaranteed that warp yarns can be fed to the weaving process at even and constant tension. The active continuous warp feeding system avoids the problems that a passive warp feeding device feeds warp yarns to a weaving machine through a winding mechanism, the winding mechanism is seriously abraded, and the quality of cloth is deteriorated.

Description

technical field [0001] The invention relates to an active continuous let-off system for carbon fiber weaving. Background technique [0002] Because carbon fiber has excellent mechanical properties, chemical properties and electrical properties, it is widely used in aerospace, wind power industry, construction industry, automobile industry, sporting goods, conductive materials, and marine shipbuilding and other fields. With the increasing demand for carbon fiber products in various industries, the quality and output of carbon fiber fabrics are also in urgent need of follow-up. [0003] As we all know, the traditional fabric weaving process and mechanical coordination are close to perfect, but the carbon fiber fabric weaving process and equipment have just started, we cannot blindly apply traditional weaving equipment to realize the production of carbon fiber fabric. Carbon fiber has mechanical properties such as high strength, high modulus, and low elongation at break. It is...

AI Technical Summary

Problems solved by technology

[0011] The purpose of the present invention is to provide an active continuous warp let-off system for carbon fiber weaving to solve the problem in the prior art that the uniformity of the warp tension is not adjusted, or the adjustment is not enough, and the feeding and weaving process that cannot ensure the balance of the sheet yarn tension is caused. The consequence is that the quality of the carbon fiber fabric cannot be guaranteed
