Embodiment 1

[0047] figure 1 It is a schematic diagram of the three-dimensional structure of a special spindle for carbon fiber three-dimensional weaving in this embodiment, figure 2 It is a schematic diagram of the front view of a special spindle for carbon fiber three-dimensional weaving in this embodiment, as shown in figure 1 , figure 2 As shown, a special spindle rod for carbon fiber three-dimensional weaving includes a yarn shaft kit 1, the yarn shaft kit 1 is a hollow shaft body, and a wire wheel installation shaft 2 is sleeved in the shaft body for winding yarn and paying off , and the yarn spool set 1 rotates radially around the spool installation shaft 2 during the wire unwinding process.

[0048] Specifically, the yarn spool kit 1 includes a yarn spool 11, a yarn spool base 12, and a yarn spool brake disc 13, the yarn spool 11 is a cylindrical tube, the yarn spool base 12, The yarn spool brake disc 13 is a disk-shaped end surface located at both ends of the yarn spool 11 , ...

Embodiment 2

[0081] Figure 8 It is a schematic structural diagram of the follower assembly in this embodiment, such as Figure 8 As shown, the structure of this implementation is similar to that of Embodiment 1, the only difference is that the structure of the follower device is different, and there is no transverse guide hole arranged radially along the yarn shaft sleeve 1 in the middle of the wire routing column 3, that is, The follow-up assembly does not include the guide eye 9.

[0082] The follow-up assembly includes a slidable and displaceable self-adjusting wiring device 4 and a self-adjusting connection module 6 that connects the self-adjusting wiring device 4 to the bottom of the wiring column 3, and the self-adjusting connection module 6 It includes a self-adjusting tension spring 62, and the self-adjusting wiring device 4 has a hole for wiring.

[0083] Specifically, the opening groove 32 of the wiring post is a "window" structure located at the lower part of the wiring post ...

Abstract

The invention discloses a special spindle blade for carbon fiber three-dimensional weaving. The spindle blade comprises a yarn shaft sleeve piece and a yarn wheel installation shaft arranged in the yarn shaft sleeve piece in a sleeved mode; a sliding groove is formed in the lower portion of the yarn wheel installation shaft; a broken yarn protection device is connected to the sliding groove; the yarn shaft sleeve piece comprises a yarn shaft, a yarn shaft base and a yarn shaft brake disc; a yarn wheel seat fixed to the yarn wheel installation shaft is arranged below the yarn shaft base; one side of the yarn wheel seat is connected with a yarn passing column; the top end of the yarn passing column is matched with the yarn shaft sleeve piece through a hinge assembly; and the yarn passing column comprises a follow-up assembly capable of relatively moving in a yarn drawing and releasing process. The spindle blade has the advantages that the structure is simple, the tension is stable during carbon fiber yarn drawing and releasing, yarn output is smooth, damage to carbon fiber yarn is relatively small, and the placement dimension is not limited when the special spindle blade for carbon fiber three-dimensional weaving is used.

Description

technical field [0001] The present application relates to the technical field of three-dimensional weaving machinery, in particular to a special spindle rod for three-dimensional weaving of carbon fibers. Background technique [0002] Three-dimensional weaving technology is an extension of two-dimensional weaving technology. It uses a yarn carrier to move precisely along a predetermined trajectory on a plane, and then realizes the interweaving of yarns in X, Y, and Z three-dimensional spaces to form a three-dimensional weaving fabric. Due to the advantages of high strength, high modulus, high temperature resistance, corrosion resistance, and light weight, carbon fiber is widely used in key industrial fields such as aviation composite materials and aerospace ablation-resistant composite materials. It has irreplaceable advantages of other chemical fibers and is widely used. , carbon fiber has a tendency to replace metal materials as high-temperature aerospace materials, but th...
