An all-in-one machine for primary twisting, plying, and multiple twisting for ceramic fibers

Abstract

The invention provides an integrated machine for primary twisting, plying and twisting of ceramic fibers, comprising: a main body support; a sun disk and a plurality of planetary wheels mounted on the main body support; coaxial with each of the planetary wheels and fixed on the A plurality of wire feeders on the sun disk; a plurality of first godets arranged above each of the wire feeders; a plurality of second godets above the plurality of first godets ; After the ceramic fibers on each of the described spinning machines pass through the outside of the first godet wheel, they are introduced into the second godet wheel, so that multiple strands of ceramic fibers are plyed at the second godet wheel, and passed through the second godet wheel. The rotation of the plurality of planetary wheels and the revolution of the sun disk realize primary twisting and re-twisting. The invention has the advantages of simple structure, reasonable design and convenient operation, and can realize the primary twisting, plying and re-twisting of multiple strands of ceramic fibers at one time.

Description

technical field [0001] The invention belongs to the field of ceramic fiber production, and in particular relates to an integrated machine for primary twisting, plying and double twisting for ceramic fibers. Background technique [0002] Different from traditional textile raw materials (cotton, wool, silk, hemp, chemical fiber, etc.) and metal filament materials, ceramic fibers have the unique characteristics of high temperature resistance, corrosion resistance and creep resistance. Metallurgy, chemical industry and other fields have a wide range of applications and are important strategic basic materials. [0003] In the textile process, ply twisting is the key link of fiber quality control in the whole preparation process. By twisting - plying - re-twisting the multi-strand fibers, the properties such as the strength of the fiber bundles can be improved, and the wovenability of the fibers can be improved. [0004] At present, the equipment that can be used for fiber plyin...

AI Technical Summary

Problems solved by technology

[0004] At present, there are twisting machines, two-for-one twisting machines, etc. that can be used in the market for fiber ply twisting. Most of these equipment are used for chemical fiber, glass fiber and carbon fiber, and these equipment have high speed, high friction and complex structure.

Ceramic fibers have special physical and mechanical properties of high tensile strength but low elongation at break. The existing ply-twisting equipment performs the twisting, plying, and re-twisting of ceramic fibers step by step during operation, and the process is very long. , the wear of ceramic fibers is very serious, and problems such as broken wires, fluffing, twisting defects and poor cohesion are prone to occur

Therefore, in view of the characteristics of ceramic fibers that are easy to wear, broken filaments, and fluff, it is necessary to solve the defects of the current ply twisting equipment such as step-by-step, long process, and serious wear of ceramic fibers.
