Fiber bundle dividing and washing method and device

Abstract

The invention relates to a fiber bundle dividing and washing method and a fiber bundle dividing and washing device. The method comprises the following steps of: 1) arranging a plurality of groups of fiber dividing and washing units and a fiber output unit on a frame, wherein each unit is provided with a running rotating crawler; 2) passing a feeding roller through a crawler input end of each fiber dividing and washing unit so as to convey the fiber bundle forward, making the fiber bundle enter a fiber dividing and washing area which is provided with a beater and a fiber dividing roller at intervals, simultaneously opening a high pressure water pipe which is arranged above the beater and the fiber dividing roller, and performing washing soaking, beating, carding and fiber dividing on the fiber bundle edges; 3) feeding the fiber treated by the previous fiber dividing and washing unit to the next fiber dividing and washing unit for continuous fiber dividing and washing; and 4) feeding the fiber treated by the last fiber dividing and washing unit into a fiber dividing input area, performing water squeezing operation through a squeezing roll, feeding the fiber into a cloth arrangement mechanism, arranging and folding the strip-shaped fiber through the cloth arrangement mechanism, and feeding the fiber into a fiber storage box. The fiber bundle dividing and washing method and the fiber bundle dividing and washing device can be widely applied to fiber dividing and washing treatment for various bast fibers, leaf fibers, and grass family fibers.

Description

technical field [0001] The invention relates to a fiber bundle washing method and equipment, in particular to a fiber bundle splitting and washing method and device for degumming bast fibers, grass fibers, leaf fibers and the like. Background technique [0002] The main components of bast fiber are pectin, hemicellulose, cellulose and lignin, etc. After mechanical, chemical or biological degumming of bast fiber, many pectin and lignin still adhere to the surface of the fiber and cannot be separated , must be washed down with water. At present, the industrial washing method of hemp fiber is mainly to use manual beating or disc beating machine to beat and so on. Among them, the principles of the disc knocking machine and the manual knocking are both to use physical and mechanical effects to remove the gum in the raw hemp and retain the cellulose component. However, the quality of the products processed by these methods is difficult to control, not only damages the fibers, ma...

Problems solved by technology

However, the quality of the products processed by these methods is difficult to control. Not only will the fibers be damaged and the fibers will be confused, but also the processing efficiency is low, the noise and labor intensity are high, so it is difficult to popularize and apply on a large scale.
