First twisting, stranding and second twisting all-in-one machine for ceramic fibers

Abstract

The invention provides a first twisting, stranding and second twisting all-in-one machine for ceramic fibers. The machine comprises a main body support; a sun disc and multiple planet wheels mounted on the main body support; a plurality of yarn releasing machines coaxial with the planet wheels and fixed on the sun disc; a plurality of first yarn guide wheels arranged above the yarn releasing machines; and second yarn guide wheels arranged above the plurality of first yarn guide wheels. The ceramic fibers on the yarn releasing machines pass through the outer sides of the first yarn guide wheels and then are introduced into the second yarn guide wheels, so that the multiple strands of ceramic fibers are stranded at the second yarn guide wheels; and first twisting and second twisting are realized through rotation of the planet wheels and revolution of the sun disc. The machine is simple in structure, reasonable in design, easy and convenient to operate and capable of achieving first twisting, stranding and second twisting of the multiple strands of ceramic fibers at a 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] Ceramic fiber is different from traditional textile raw materials (cotton, wool, silk, hemp, chemical fiber, etc.) and metal filament materials. It has the characteristics of high temperature resistance, corrosion resistance, and creep resistance unique to ceramic materials. It is widely used in metallurgy, chemical industry and other fields, and is an important strategic basic material. [0003] In textile technology, 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 bundle strength and other properties of the fibers can be improved, and the weavability of the fibers can be improved. [0004] At present, there are twisting machines, two-for-on...

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.
