Preferably, the braided rod 212 is a hollow steel tube. The knitting rod 212 has the function of replacing knitting yarns, namely, when knitting is carried out, yarns of one system required by knitting are replaced by the knitting rod 212, after knitting is finished and forming is finished, the knitting rod 212 is pulled out, meanwhile, the knitting yarns are led in the position of the knitting rod 212 and the pulling-out direction, knitting of a structural part on a knitting unit is finished, and by adopting the knitting rod 212 to replace axial yarns, the situation that high-performance materials serving as the axial yarns are damaged or broken by artificial knitting and further the performance of a knitted preform is affected can be avoided. The fineness of the knitting yarn 212 is determined by the knitting material, and the total length is 500 mm.

When the three-dimensional braided preform is used, according to the design requirement of a braided structure rule, the axial height of the three-dimensional braided preform, namely the distance between the upper support 30 and the lower support 40, needs to be determined; the density of the fixed knuckles on the radiation bar 501 and the lower support 40 placed on the upper support 30 is determined according to the designed size of the woven preform, and then the actual structure of the woven yarn support and the woven unit 20 is determined by adjusting the angle of the single movable piece 207 of the fixed knuckle, the position of the single movable piece 207 on the woven bar 212 and the position of the control valve 601 on the radiation bar 501, so that the change of the inclination angle of the woven bar 212 and the used length d of the weaving and the change of the size of the maximum cross section of the weaving, namely the change of the taper of the cone of the three-dimensional woven preform, the height of the three-dimensional woven member and the shape of the cross section of the cone are realized.

After the position and the structure of the knitting unit 20, the knitting yarn support and other parts are determined, the integral installation of the simple knitting device is completed. When actual weaving is carried out, the weaving method is characterized in that: 4 strands of twisted basalt roving are used as raw materials, the fineness is about 3-4 mm, therefore, the fineness of the weaving rod 212 is 3.5mm, and the size of the single movable piece 207 for fixing the knuckle corresponds to the fineness.

Weaving process of the three-dimensional material: the knitting yarn 80 is led out from the yarn guide cylinder 90, bypasses the radiation rod 501, is sleeved with the control valve 601 which can stretch up and down in a certain range, when knitting is needed, the ejector rod 603 of the control valve 601 is pressed to open the yarn channel 100 to enable the knitting yarn 80 to pass through, after the knitting yarn 80 penetrates, the ejector rod 603 of the control valve 601 is pressed again to enable the telescopic rod 605 to be inserted into the supporting rod 215 to close the yarn channel 100, each knitting yarn 80 needing to be knitted is smoothly guided into the knitting unit 20 according to the step, and the knitting yarn 80 is knitted in the knitting unit 20 according to a certain knitting rule and a certain yarn adding and reducing rule.

When the knitting unit 20 performs knitting, the knitting rods 212 are used as substitute phases of axial yarns, the knitting yarns 80 sequentially penetrate through the knitting rods 212 at corresponding positions according to a designed knitting rule, after all the knitting yarns 80 are wound, the knitting rods 212 need to be off-machine processed, and the axial yarns 200 are introduced while the knitting rods 212 replacing the axial yarns are pulled out one by one. When the hollow knitting rod 212 is used for axial yarn replacement, the leading wire 300 which can pass through the knitting rod 212 needs to be tied tightly at the head end of the axial yarn 200, as shown in fig. 12, the leading wire 300 firstly passes through the hollow knitting rod 212, meanwhile, the head ends of the knitting rod 212 and the leading wire 300 are pulled, the leading wire 300 is pulled upwards, the lower axial yarn 200 is pulled to move upwards, and in the process of pulling the knitting rod 212, the axial yarn 200 is inserted along the pulling position of the knitting rod 212, so that the knitting between the knitting yarn 80 and the axial yarn 200 is realized. And after the weaving rod 212 is completely pulled out, the weaving work is completely finished, and the conical weaving piece is obtained.

By reasonably adjusting the positions, densities and structural forms of the weaving units 20 and the weaving yarn supports, a new weaving framework is obtained, and further weaving preformed bodies with different variable cross sections or special-shaped cross sections such as pyramids can be formed.

As shown in fig. 13 and 14, the present embodiment is different from the first embodiment in that: the fixed plate 203 of mounting 202 extends with the part that lower supporter 40 is connected, can realize weaving the cone structure range of change more extensively, in order to reduce the limitation of weaving the angle transform, the moving mechanism includes two at least movable bodies 220 that set up side by side, every movable body 220 includes hollow carrier bar 221, install the connecting block 222 on carrier bar 221, the cooperation is provided with third eyelet 223 on the connecting block 222 of breach 205 department, movable body 220 can rotate, can realize weaving multilayer three-dimensional structure. Specifically, each control valve assembly includes three control valves 601, the steering rod assembly includes three steering rods, and the number of the movable bodies 220 is three, so that a three-layer three-dimensional structure can be woven. Preferably, the three movable bodies 220 are integrally formed into a whole, so that the stability of the movable mechanism and the smoothness of the rotation of the movable mechanism are improved.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
