Abstract

The invention discloses a chopped fiber dispersion machine, which is characterized in that toothed plate dispersion teeth positioned on the inner circumferential surface of a protective shell and inner barrel dispersion teeth positioned on the outer circumferential surface of a rotary inner barrel are arranged in a staggered manner; a motor drives the rotary inner barrel to rotate; chopped yarns are fed into a material inlet; the chopped yarns are dispersed at the material inlet by utilizing the mutual impact effect of high rotating speeds of the dispersing teeth; and when the chopped yarns are dragged into the barrel body and slide relative to the surfaces of the dispersing teeth of the adjacent inner barrel and outer barrel, the chopped yarns are separated and discharged along with airflow generated by high-speed rotation of the inner barrel, so that finally the purpose of dispersing fibers is achieved. According to the invention, blocky fibers can be dispersed into fibers with the diameter of 1 mm or below, the dispersion rate can reach 95% or above, the dispersion rate of the fibers with the diameter of 3 mm or below can reach 99%, abrasion of dispersion equipment to the fibersis very small, the phenomenon that the surfaces of the fibers are abraded and fuzzed is basically avoided, and the fiber dispersity is good.

Description

technical field [0001] The invention relates to the field of chopped fiber preparation, in particular to a chopped fiber disperser. Background technique [0002] Glass fiber acid leaching is an important and indispensable process for the production of glass fiber chopped strand products. It is to precipitate the phase-separated non-siliceous phase in the glass fiber structure under the action of acid to make the SiO2 content in the structure Reach above 96%. Because the glass fiber presents a compact block structure ranging from 60mm to 80mm after wire drawing and chopping, especially at the knife edge position at both ends, after high-speed cutting by the knife, the yarn and yarn are bonded together due to the presence of the sizing agent. Difficult to disperse. During the reaction process of glass fiber and acid leaching, the outer fiber first reacts with the acid solution, which causes the alkaline product produced by the chopped strand reaction to be enriched in a larg...
