Problems solved by technology

[0003] For a long time, three-dimensional weaving is carried out in a semi-mechanical and semi-manual way, which makes the cost of three-dimensional weaving high and slow, and the existing three-dimensional weaving machine uses gear transmission or other transmission methods to drive the yarn movement, and when the yarn When the number continues to increase, the transmission will become more and more difficult, or even impossible, which directly affects the wide application of 3D braiding

Embodiment 1

[0052] 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 within the frame 900. During the knitting process, the knitting station 800 rotates circumferentially around the axis of the knitting station 800, and under the clamping action of the knitting station 800, each yarn storage device 100 wraps around the outer circumference of the knitting station 800 and on the end face 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.

[0053] In this embodiment, the frame 900 is located at one end close to the knitting surface and...

Embodiment 2

[0058] 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.

[0059] 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

[0068] Such as Figure 2 to Figure 8 As shown, a large-capacity yarn storage device 100 for a three-dimensional knitting device 1000 is introduced in this embodiment. 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,

[0069] 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 u...

Abstract

The invention discloses a high-capacity yarn storage device for three-dimensional automatic knitting equipment. The high-capacity yarn storage device is characterized by comprising a yarn storage pipe, a yarn delivering unit for delivering yarn to the knitting surface from the yarn storage pipe and a tension adjusting unit for adjusting yarn tension in the yarn delivering process, so that the yarnis unwound under the effect of the tension. By arranging the yarn delivering unit and the tension adjusting unit, the yarn can be delivered to the knitting surface through the yarn delivering unit for yarn knitting, the knitting tension is more even, the tension can be adjusted at any time through the tension adjusting unit in the knitting process, and the tension adjusting range is widened.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional automatic weaving equipment, and in particular relates to a large-capacity yarn storage device for three-dimensional automatic weaving equipment, especially a large-capacity yarn storage device suitable for high-performance fiber weaving. Background technique [0002] Three-dimensional weaving is a kind of fabric forming process, which can support cables, belts, nets, plates, pipes and special-shaped fabrics through three-dimensional weaving process with high-performance fibers. This kind of braid has unique structure and function, and has high strength, high modulus, high Reliability, high pressure resistance, wear resistance, precise and controllable elongation, etc., are special products for national strategies and important people's livelihoods such as aerospace, national defense and military industry, and marine exploration. However, the automatic forming equipment of this kind of f...
