Problems solved by technology

However, the automatic forming equipment of this kind of fabric has been monopolized by Europe, America and Russia for a long time, which seriously restricts the development of my country's three-dimensional weaving industry
[0003] In terms of three-dimensional automatic knitting machines, relevant researchers in my country have done a lot of work, such as the Chinese patents whose publication numbers are CN204644597U and CN1312408A, but the disclosed three-dimensional automatic knitting machines can only be applied to the weaving of a specific, single-structure three-dimensional braided fabric. The equipment cost of three-dimensional weaving is raised; the development and trial weaving of new three-dimensional weaving technology cannot be carried out, which is not conducive to the development of three-dimensional weaving technology; it cannot meet the needs of strong designability and structural diversification of three-dimensional weaving technology, which limits three-dimensional weaving technology Applications in the field of composite materials

Embodiment 1

[0050] 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.

[0051] In this embodiment, the frame 900 is located at one end close to the knitting surface and is provided with a suppo...

Embodiment 2

[0056] 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.

[0057] 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

[0066] Such as Figure 2 to Figure 8 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,

[0067] 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 discloses three-dimensional automatic weaving equipment. The equipment comprises a framework, multiple yarn storage devices and multiple weaving stations, and the weaving stations are arranged in the hollow interior of the framework and form an array in the framework; in the weaving process, the weaving stations rotate circumferentially around the axes of the weaving stations, underthe clamping effect of the weaving stations, all the yarn storage devices move on the end face, close to a weaving face, of the framework around the peripheries of the weaving stations, so that yarn carried by all the yarn storage devices is mutually woven, and a three-dimensional woven fabric is formed at the weaving face. By means of the three-dimensional automatic weaving equipment, the yarn storage devices shuttle back and forth in track discs of the weaving stations, the yarn storage devices carry the yarn to be interwovenr in a weaving space above the track discs, and the function of automatic three-dimensional weaving of all the yarn is achieved. The equipment is simple in structure, has an obvious effect and is suitable for application and popularization.

Description

technical field [0001] The invention belongs to the field of textile machinery, and in particular relates to a three-dimensional automatic weaving device. 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. However, the automatic forming equipment of this kind of fabric has been monopolized by Europe, America and Russia for a long time, which seriously restricts the development of my country's three-dimensional weaving industry. [0003] In terms of three-dimensional automatic knitting machines, relevant researchers in my country have done a lot of work, such as the Chinese patents whose public...
