Abstract

The invention belongs to the technical field of fiber tow treatment and particularly relates to a fiber tow treatment device and method. The fiber tow treatment device comprises a front traction machine, a mounting rack, an upper cavity, a lower cavity and a rear traction machine, wherein the front traction machine, the upper cavity and the rear traction machine are sequentially arranged on the upper surface of the mounting rack from left to right, fiber inlets / outlets of the front traction machine, the upper cavity and the rear traction machine are located on the same horizontal straight line, and pressing rollers are arranged above drafting rollers of the front traction machine and the rear traction machine. By adopting the fiber tow treatment device and the fiber tow treatment method, the problems of poor stability and poor adjustability of fiber tows when the fiber tows advance in the existing air fiber spreading process are solved, and the fiber spreading atmosphere of the fiber tow treatment device can be uniformly distributed and concentrated in an effective area, so that the influence of turbulent flow on the tows is effectively reduced, the tow dispersing effect is improved, and adverse variables in an adjusting process are decreased.

Description

technical field [0001] The invention belongs to the technical field of fiber tow processing, and in particular relates to a processing device and method for fiber tow. Background technique [0002] In the process of fiber application, it is usually necessary to make the fiber tow as thin as possible in the unfolded state, that is, fiber spreading treatment. At present, there are two main methods of spreading fibers in common use. One method is to use mechanical means to spread fibers, see Chinese patent (CN201520104863; CN201821646155); another method is to use air to spread fibers, see Chinese patent (CN201480072709). An airflow facing or at an angle to the fiber is added between the drafting rollers, and the high-speed airflow is used to realize the expansion of the fiber tow. The above two methods have obvious defects. The mechanical fiber spreading method will inevitably cause damage to the fiber, while in the air fiber spreading method, due to the unstable air flow, t...
