Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] figure 1 It shows a schematic structural view of the device for widening and arranging wide-width fibers in this embodiment. Referring to the diagram, the device includes: a creel 1, on which a multi-spindle fiber is arranged, and the fiber is a fiber before widening; an ultrasonic groove 4, a multi-spindle The fiber passes through it, and an ultrasonic transducer is arranged inside it for oscillating the liquid dissolved in it so as to widen the fiber in the liquid; the prepreg arrangement unit is arranged behind the outlet of the widened fiber , the stretched fibers are arranged and wound into rolls in the prepreg arranging unit.

[0023] Preferably, the creel 1...

Abstract

The invention relates to fiber processing and production equipment, and discloses wide fiber widening arrangement equipment. The wide fiber widening arrangement equipment comprises a creel provided with spindles of fiber; an ultrasonic groove where spindles of fiber pass through, and an ultrasonic transducer for vibrating liquid accommodated inside to widen fiber in the liquid is arranged inside the ultrasonic groove; and a prepreg arranging unit arranged behind an outlet of widened fiber rolled in the prepreg arranging unit. According to the device provided by the invention, spindles of fiber can be simultaneously arranged into the ultrasonic groove to widen so as to realize integrated output of the wide fiber. No external forces are applied to the fiber in a whole widening process, thereby, a damage rate of the fiber is reduced, and quality of the widened fiber is improved while a structure of integral equipment is simplified.

Description

technical field [0001] The invention relates to fiber processing and production equipment, in particular to a wide-width fiber stretching and arranging equipment. Background technique [0002] Tests on fiber fabrics have shown that the thinner the fabric, the lower the mass per unit area, the smaller the deviation of its physical properties, and the better the operability of the covering. Therefore, the widening arrangement of the fiber tow is directly related to the quality of the fiber fabric. At present, airflow method and rolling method are mostly used in the processing process of fiber widening and arrangement. [0003] These two methods of widening and arranging fibers cause large fiber damage, and the fiber damage exceeds 20%. The strength and modulus of fibers treated in this way are reduced, which greatly affects the mechanical properties and quality stability of composite products. Contents of the invention [0004] (1) Technical problems to be solved [0005...
