Embodiment 1

[0066] Such as figure 1 As shown, a three-dimensional automatic weaving device 1000 is introduced in this embodiment, and the three-dimensional automatic weaving device 1000 includes a frame 900, a plurality of yarn storage devices 100 and a plurality of weaving stations 800, and the weaving stations 800 are arranged in the hollow inside of the frame 900 , and form an array in the frame 900. During the knitting process, the knitting station 800 rotates circumferentially around the axis of the knitting station 800, and each yarn storage device 100 is clamped by the knitting station 800, around the outer circumference of the knitting station 800, on the end surface of the frame 900 close to the knitting surface move so that the yarns carried by each yarn storage device 100 knit each other to form a three-dimensional knitting fabric at the knitting surface.

[0067] In this embodiment, the frame 900 is located at one end close to the knitting surface and is provided with a suppo...

Embodiment 2

[0072] Such as figure 1 As shown, in this embodiment, the yarn storage device 100 includes a base disc column 107 and a base 101, the base 101 and the base disc column 107 both extend along the axial direction of the knitting station 800, and the base disc column 107 is arranged on the side of the yarn storage device 100 One end away from the weaving surface, the base 101 is arranged on the end of the yarn storage device 100 away from the weaving surface, the base disc column 107 is fixedly arranged with the base 101, the diameter of the base 101 is much larger than the diameter of the base disc column 107, the base disc column 107 and the base 101 coaxial setting.

[0073] In this embodiment, the base 101 rests on the support plate 901, the base disc column 107 extends into the frame 900 through the circular track 904, and the knitting station 800 clamps the base disc column 107 and rotates circumferentially to drive the yarn storage device 100 It moves around the outer circ...

Embodiment 3

[0082] Such as Figure 2 to Figure 4 As shown, in this embodiment, a large-capacity yarn storage device 100 for a three-dimensional knitting device 1000 is introduced. The thread transfer unit 500 is used to transfer the yarn on the yarn storage tube 100 from the yarn storage tube 100 to the knitting surface, and the tension adjustment unit 600 is used to adjust the yarn tension during the yarn transfer process, so that the yarn is Unwind under tension. By setting the yarn transfer unit and the tension adjustment unit,

[0083] In this embodiment, the yarn transfer unit 500 includes an upper wire passing wheel 104 and a lower wire passing wheel 105, the upper wire passing wheel 104 is arranged at one end of the yarn storage device 100 close to the knitting surface, and the lower wire passing wheel 105 is arranged at the yarn storage device At the end of 100 away from the weaving surface, the yarn is delivered to the weaving surface from the yarn storage tube 108 through the ...

Abstract

The invention belongs to the field of operation methods of weaving devices, and relates to an operation method of a three-dimensional automatic weaving device. The three-dimensional automatic weavingdevice comprises a plurality of yarn storage devices and a plurality of weaving stations. The weaving stations are distributed in arrays. Each weaving station comprises a body section and a clip section, wherein the clip section is arranged on the body section and can rotate relative to the axis of the body section, the clip section is provided with a plurality of clips for clamping the corresponding yarn storage devices, and the yarn storage devices are arranged around the weaving station and opposite to the clips. The three-dimensional automatic weaving device controls the clip sections to extend at least one clip to clamp the opposite yarn storage devices. The clip sections rotate to drive the yarn storage devices to circumferentially rotate by a certain angle and then stop, the clips retreat, the three-dimensional automatic weaving device controls the clip sections according to a weaving program to sequentially repeat the process, and yarn is interwoven to obtain a three-dimensional braided fabric. The yarn storage devices are clamped by the clips of the clip sections and driven to rotate relative to the body sections, and the yarn is interwoven to obtain the three-dimensionalbraided fabric.

Description

technical field [0001] The invention belongs to the field of operating methods of knitting equipment, and in particular relates to an operating method of three-dimensional automatic knitting equipment. Background technique [0002] Three-dimensional braiding is a three-dimensional braiding process. High-performance fibers can be woven into cables, belts, nets, plates, pipes, special-shaped three-dimensional braids, etc., which have unique structures and functions. It has the characteristics of high strength, high modulus, high reliability, high pressure resistance, wear resistance, precise and controllable elongation, and the automatic three-dimensional weaving equipment is the key to the industrialization of three-dimensional weaving technology. [0003] The Chinese patents whose publication numbers are CN204644597U and CN1312408A, but the disclosed three-dimensional automatic knitting machine can only be applied to the weaving of a certain specific, single-structure three-...
