Figure 4 As shown, at least one circle of second holes 401 are distributed on the upper end of the lower support member 40, and a third threaded hole (not shown in the figure) is arranged on the lower end of the lower support member 40. In actual application, the lower support member 40 is fixed to the rotating sleeve 70 with the third bolt 403. Furthermore, two circles of first holes 301 are arranged on the upper end of the upper support member 30, and the first holes 301 of the inner circle correspond to the first holes 301 of the outer circle. Two circles of second holes 401 are arranged on the upper end of the lower support member 40, and the second holes 401 of the inner circle correspond to the second holes 401 of the outer circle. The maximum diameter of the upper support member 30 and the lower support member 40 is about 300 mm. The diameters of the first hole 301 and the second hole 401 are 3 mm. The structure of the upper support member 30 and the lower support member 40 in this embodiment is suitable for weaving cylinders or cones. In other embodiments, the cross-sections of the upper support member 30 and the lower support member 40 are both polygonal, which can realize the changes of different braiding yarn support structures, thereby realizing the weaving of three-dimensional structures of other shapes such as pyramids.

More specifically, a plurality of through holes 502 are arranged at intervals on the radiation rod 501, and the radiation rod 501 is fixed on the upper support member 30 by inserting a positioning pin (not shown in the figure) through the through hole 502 into the first hole 301. Preferably, the length of the radiation rod 501 is 200 mm. Preferably, the diameter of the through hole 502 is 3 mm.

[0046] like Figure 5 , Figure 6As shown, in this embodiment, the control valve 601 includes a sleeve 602, a push rod 603, a rotating part 604, a telescopic rod 605 and an elastic part. The sleeve 602 is installed on the radiation rod 501, the push rod 603 can move up and down along the sleeve 602, the push rod 603 can drive the rotating part 604 to rotate and engage with the sleeve 602, the rotating part 604 cooperates with the telescopic rod 605, the elastic part is sleeved on the telescopic rod 605, the upper end of the elastic part abuts against the telescopic rod 605, and the lower end of the elastic part abuts against the radiation rod 501.

The lower part of the rotating member 604 is provided with a plurality of third ridges 614 along the circumferential direction, and the top surface of the third ridge 614 is a second inclined surface 615. The sum of the number of the first grooves 606 and the second grooves 607 is equal to the number of the second ridges 613, and the sum of the number of the first grooves 606 and the second grooves 607 is twice the number of the third ridges 614.

[0048] Specifically, the elastic member is a spring 617 , a protrusion 618 is provided on the telescopic rod 605 , and the upper end of the spring 617 abuts against the protrusion 618 .

[0049] In addition, the movable range of the telescopic rod 605 can be effectively changed by changing the rod length above the second protrusion 613 of the top rod 603 and the length of the first groove 606 and the second groove 608 of the sleeve 602.

[0050] In the initial state, the multiple second protrusions 613 of the top rod 603 are respectively engaged in the multiple first grooves 606 and the multiple second grooves 608, and the multiple third protrusions 614 of the rotating member 604 are respectively engaged in the multiple first grooves 606. At this time, there is a gap between the telescopic rod 605 and the weaving unit 20, and they are separated. By manually pressing the top rod 603, the multiple first protrusions 607 of the top rod 603 move downward along the multiple first grooves 606 and the multiple second grooves 608 respectively, the serrated protrusion 612 of the top rod 603 presses against the second inclined surface 615 of the third protrusion 614 of the rotating member 604, the top rod 603 pushes the third protrusion 614 of the rotating member 604 to leave the first groove 606, the second inclined surface 615 of the third protrusion 614 moves along the third inclined surface 619 of the serrated protrusion 612 of the top rod 603, the rotating member 604 rotates a certain angle, the top rod 603 is released, the second inclined surface 615 of the third protrusion 614 of the rotating member 604 presses against the oblique mouth 609 of the sleeve 602, the spring 617 is compressed, and the telescopic rod 605 extends into the weaving unit 20 to achieve connection with the weaving unit 2 0; press the top rod 603 again, the serrated protrusion 612 of the top rod 603 presses against the second inclined surface 615 of the third ridge 614 of the rotating member 604, the top rod 603 pushes the third ridge 614 of the rotating member 604 to leave the oblique mouth 609 of the sleeve 602, the second inclined surface 615 of the third ridge 614 moves along the third inclined surface 619 of the serrated protrusion 612 of the top rod 603, the rotating member 604 rotates a certain angle, release the top rod 603, the second inclined surface 615 of the third ridge 614 of the rotating member 604 moves along the first inclined surface 610 of the sleeve 602, the rotating member 604 rotates a certain angle so that the third ridge 614 moves into the first groove 606 under the action of elastic force, the spring 617 returns to its original position, and the telescopic rod 605 is separated from the weaving unit 20.

[0051] During the actual weaving process, the control valve 601 plays the role of a clutch, mainly to achieve that when a certain axial yarn is weaving with the weaving yarn, the telescopic rod 605 of the control valve 601 is retracted, and a gap is created between the telescopic rod 605 and the weaving unit 20 to form a yarn channel, so that the weaving yarn can pass smoothly through the yarn channel at the upper end of the axial yarn, so as to avoid occasional weaving errors caused by the weaving yarn being pierced through the middle or lower end of the axial yarn, or the ambiguity of the weaving rules that may occur when multiple layers and multiple yarns are weaved; similarly, on other axial yarns that do not need to be weaved yet, the telescopic rod 605 of the control valve 601 is extended to close the yarn channel, and each yarn that needs to be weaved is smoothly introduced into the weaving unit 20.

[0052] In this embodiment, the weaving unit 20 includes a plurality of weaving components 201, such as Figure 8 , Fig.11As shown, each weaving component 201 includes a fixed steering knuckle and a steering rod assembly, the fixed steering knuckle includes a fixing part 202 and a movable mechanism rotatably connected to the fixing part 202, the fixing part 202 is mounted on the lower support part 40, the steering rod assembly is mounted on the movable mechanism, the steering rod assembly includes at least one steering rod, the weaving unit 20 can be flexibly rotated around the frame 10 through the lower support part 40 via the rotating sleeve 70, the taper of the steering rod can be adjusted arbitrarily, and the height of the weaving preform and the size of the upper and lower cross-sections can also be adjusted.

[0053] The fixing member 202 includes a fixing plate 203, at least one mounting hole 204 opened at one end of the fixing plate 203, a notch 205 opened at the other end of the fixing plate 203, and two first holes 206 connected to the notch 205.

[0054] like Fig. 9 As shown, the movable mechanism includes a single movable member 207, which is T-shaped and includes a hollow cylinder 208, a protrusion 209 disposed on the cylinder 208, and a second hole 210 is disposed on the protrusion 209. The protrusion 209 is matched in the notch 205. Specifically, the protrusion 209 is inserted into the notch 205, and a movable pin (not shown in the figure) passes through one of the first holes 206, the second hole 210, and another first hole 206. The protrusion 209 can rotate around the movable pin to drive the cylinder 208 to rotate. Preferably, the cylinder 208 and the protrusion 209 are integrally formed as a whole to improve the stability of the single movable member 207 and the smoothness of rotation.

[0055] like Fig.10As shown, the steering rod includes an angle adjustment member 211 and a hollow braiding rod 212, one end of the braiding rod 212 is mounted on the angle adjustment member 211, and the other end is mounted on the movable mechanism. More specifically, the angle adjustment member 211 includes a mounting seat 213, a spherical hinge 214 matched with the mounting seat 213, and a support rod 215 mounted on the spherical hinge 214. One end of the braiding rod 212 is placed in the mounting seat 213, and the other end is placed in the cylinder 208. The mounting seat 213 can rotate around the spherical hinge 214 to drive the braiding rod 212 to rotate, adjust the inclination angle of the braiding rod 212, that is, the taper of the braided preform, thereby changing the maximum hypotenuse length of the braided preform. Preferably, the braiding rod 212 is a hollow steel pipe. The braiding rod 212 replaces the braiding yarn, that is, when braiding, the yarn of a system required for braiding is replaced by the braiding rod 212. After the braiding is completed and the molding is completed, the braiding rod 212 is removed, and the braiding yarn is introduced along the position and the direction of the braiding rod 212 to complete the braiding of the structural part on the braiding unit 20. By using the braiding rod 212 instead of the axial yarn, it is possible to avoid artificial braiding damage or breakage of the high-performance material as the axial yarn, thereby affecting the performance of the braided preform. The fineness of the braiding yarn 212 is determined by the braiding material, and the total length is 500mm.

[0056] When the present invention is in use, according to the design requirements of the weaving structure law, it is first necessary to determine the axial height of the three-dimensional weaving preform, that is, the distance between the upper support 30 and the lower support 40; the radiation rod 501 placed on the upper support 30 and the fixed knuckle density on the lower support 40 are determined according to the designed size of the weaving preform, and then by adjusting the angle of the single movable part 207 of the fixed knuckle, the position of the single movable part 207 on the weaving rod 212 and the position of the control valve 601 on the radiation rod 501, the actual structure of the weaving yarn support and the weaving unit 20 is clarified, and the changes in the inclination angle of the weaving rod 212 and the weaving length d and the size of the maximum weaving cross-section, that is, the taper of the cone of the three-dimensional weaving preform, the height of the three-dimensional weaving part and the cross-sectional shape of the cone are realized.

[0057] After determining the position and structure of the weaving unit 20, the weaving yarn support and other parts, the overall installation of the simple weaving device is completed. When actually weaving, the brittle high-performance material: 4-strand basalt roving is used as the raw material, and the fineness is about 3-4mm. Therefore, the fineness of the weaving rod 212 is 3.5mm, and the size of the single movable part 207 of the fixed steering knuckle corresponds to it.

[0058] The weaving process of three-dimensional materials: the weaving yarn 80 is led out from the yarn guide tube 90, bypasses the radiation rod 501, and passes through the control valve 601 that can be extended and retracted up and down within a certain range. When weaving is required, the top rod 603 of the control valve 601 is pressed to open the yarn channel 100 to allow the weaving yarn 80 to pass through. After the weaving yarn 80 is inserted, the top rod 603 of the control valve 601 is pressed again to allow the telescopic rod 605 to be inserted into the support rod 215, and the yarn channel 100 is closed. According to this step, each weaving yarn 80 that needs to be weaved is smoothly introduced into the weaving unit 20, and the weaving yarn 80 is woven in the weaving unit 20 according to a certain weaving rule and in combination with a certain adding yarn and reducing yarn rule.

[0059] When the weaving unit 20 is weaving, the weaving rod 212 is used as a replacement for the axial yarn. The weaving yarn 80 is passed through the weaving rod 212 at the corresponding position in sequence according to the designed weaving rules. After the weaving yarn 80 is completely wound, it is necessary to remove the weaving rod 212 that replaces the axial yarn one by one and introduce the axial yarn 200 at the same time. When the hollow weaving rod 212 is used to replace the axial yarn, the lead wire 300 that can pass through the weaving rod 212 needs to be tied tightly at the head end of the axial yarn 200, such as Fig.12 As shown, first, the lead wire 300 is passed through the hollow braiding rod 212, and the braiding rod 212 and the head end of the lead wire 300 are pulled upward, and the lead wire 300 pulls the shaft yarn 200 below to move upward. During the process of the braiding rod 212 being pulled out, the shaft yarn 200 is inserted along the pulled-out position of the braiding rod 212, so as to realize the braiding between the braiding yarn 80 and the shaft yarn 200. When the braiding rod 212 is completely pulled out, the braiding work is completely completed, and a conical braided piece is obtained.

[0060] By reasonably adjusting the position, density and structural form of the weaving unit 20 and the weaving yarn support, a new weaving frame can be obtained, and then different variable-section or special-section weaving preforms such as pyramids can be formed.
