Embodiment 1

[0030] Aiming at the problems of high brittleness, low elongation, high rigidity, serious fluffing during weaving, and decreased mechanical properties of ceramic fibers, the present embodiment provides an auxiliary ceramic fiber fabric weaving, wrapping and plying device, including:

[0031] bobbin 1, which is used to draw out ceramic fiber bundles;

[0032] The hollow spindle 3 is surrounded by cellulose fibers, and the hollow spindle 3 is provided with a passage for the ceramic fiber bundle to pass through, and the hollow spindle 3 can rotate around its central axis;

[0033] The yarn guide hook 4 can rotate according to the rotation of the hollow spindle 3. After the ceramic fiber bundle passes through the channel, the yarn guide hook 4 guides and wraps the cellulose fibers on the hollow spindle 3 to the On the ceramic fiber bundles, the wrapped ceramic fibers are obtained;

[0034] A winding mechanism 7 is used to wind the wrapped ceramic fibers into a cylinder.

[0035]...

Embodiment 2

[0043] The present embodiment also provides a method for assisting the weaving, wrapping and plying of ceramic fiber fabrics, comprising the following steps:

[0044] Step S1: the ceramic fiber bundle is unwound through the bobbin 1, and the two ceramic fiber bundles after unwinding are merged and passed through the hollow rod 2 inside the hollow spindle 3;

[0045] Step S2: The cellulose fibers on the hollow spindle 3 bypass the yarn guide hook 4, and the yarn guide hook 4 rotates with the hollow spindle 3, and guides and wraps the cellulose fibers to the combined two ceramic strands during the rotation On the fiber bundle, the wrapped ceramic fiber is obtained;

[0046] Step S3: The wrapped ceramic fiber passes through the yarn guide handle 5, and then goes around a pair of yarn takeoff rollers 6. The bobbin 9 moves left and right on the ball screw 8 under the drive of the power device, and the wrapped ceramic fiber is rotated by rotating. The fibers are evenly wound onto t...

Abstract

The invention relates to a device and a method for assisting weaving, wrapping and stranding of a ceramic fiber fabric. The device comprises a spool, wherein the spool is used for leading out a ceramic fiber bundle; the hollow spindle is wound with cellulose fibers, a channel for ceramic fiber bundles to pass through is formed in the hollow spindle, and the hollow spindle can rotate around the central axis of the hollow spindle; the yarn guide hook can rotate according to rotation of the hollow spindle, and after the ceramic fiber bundle passes through the channel, the yarn guide hook guides the cellulose fibers on the hollow spindle and wraps the cellulose fibers on the ceramic fiber bundle, so that wrapped and formed ceramic fibers are obtained; and the winding mechanism is used for winding the wrapped and formed ceramic fibers into a barrel. According to the invention, the two fiber bundles can be stranded and wrapped while ceramic fibers are prevented from being broken, so that the frictional wear of yarns is reduced, and the weaving efficiency and mechanical properties of products are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of textile accessories, in particular to an auxiliary ceramic fiber fabric weaving, wrapping and plying device and method. Background technique [0002] Ceramic fiber textile is a new type of material with excellent thermal insulation and mechanical properties, which can be made into cloth, belt and rope of various shapes and specifications. It is suitable for heat insulation, heat preservation and sealing materials in various high temperature and strong chemical erosion environments. However, ceramic fibers are brittle and easily broken after being subjected to mechanical action during processing; the surface of the fibers is very smooth, without any curling, the cohesion between fibers is poor, and it is difficult to form a network and a strip; although it can be improved by sizing agents Its weaving property is still high, but there are still problems such as large friction, serious fluffing during weavi...
