Problems solved by technology

At present, the preparation of such special-shaped composite material prefabricated parts is not easy to achieve through semi-mechanical and semi-manual methods, and the production efficiency is low.
The main method is to perform traditional mechanical post-processing on the corresponding regular and equal-section prefabricated parts to obtain the required appearance size. During the processing, the fibers of the braid are easily damaged severely, and the structural integrity of the prefabricated parts is destroyed. The mechanical properties of composite materials are significantly reduced, and at the same time, the process is increased and the production cost is increased

Embodiment 1

[0050] like figure 1 As shown, in the present embodiment, a kind of three-dimensional automatic knitting machine is characterized in that: comprise by a plurality of knitters 3 that are used to pass the single yarn on the corresponding spool to the knitting surface; Machine base 1; a knitting machine chassis consisting of a plurality of knitting stations 2 installed on the knitting machine base 1; The yarns move to weave into a three-dimensional braid.

[0051] like figure 2 As shown, in this embodiment, the knitter 3 includes, the knitting section 5 that transmits the yarn from the chassis of the knitting machine to the knitting surface, the support section 4 that fixes the horizontal position of the knitting station, and provides yarn for the knitting machine 3 supply line segment. When performing three-dimensional weaving, the yarns set in the supply segments of each knitter 3 pass through the supporting segment 4 and the knitting segment 5 to the weaving surface in tur...

Embodiment 2

[0055] like figure 2 As shown, in this embodiment, the knitter 3 includes, the knitting section 5 that transmits the yarn from the chassis of the knitting machine to the knitting surface, the support section 4 that fixes the horizontal position of the knitting station, and the knitting section that provides the yarn for the knitting machine. for line segments.

[0056] like Figure 4 As shown, in this embodiment, the thread supply section includes a bobbin box 47, a bobbin 46 arranged in the bobbin box 47, and a wide range tension control system for controlling the tension of the yarn.

[0057] like Figure 4 As shown, in this embodiment, the support section 4 includes a wire tube 44 connected to the bobbin box 47, the wire tube 44 is provided with a support piece 43 for fixing the braider 3, and the wire tube 44 is connected to the bobbin The connecting end of the box 47 is provided with a crimping wheel 45 . The wire tube 44 is arranged as a straight tube inside for the...

Embodiment 3

[0062] like image 3 As shown, in the present embodiment, the braiding station 2 is divided into a support layer 23 for fixing the position of the braider 3 and a support layer 23 for making the braider 3 produce a braider 3 from top to bottom with the support tube 21 arranged on the braider base 1 as a pillar. Drive layer 22 for horizontal displacement.

[0063] like Image 6 As shown, in this embodiment, each braiding station 2 is provided with four bobbin sockets 25 shared with adjacent braiding stations 2 , which can fix the braider bobbin 44 at an angle of 90 degrees to each other. The knitting machine 3 can be controllably positioned relative to the knitting station 2 by moving the wire tube 44 between the different wire tube holders 25 .

[0064] like Image 6 As shown, in this embodiment, the support layer 23 is composed of an upper support plate and a lower support plate formed of discs arranged in parallel around the axis of the support tube 21, and a line that ca...

Abstract

The present invention relates to the field of textile machinery, specifically to a three-dimensional automatic knitting machine, which comprises: a plurality of same weavers (3), a knitting machine chassis and a knitting machine base (1), wherein each weaver (3) moves on the knitting machine base (1) under the effect of the knitting machine chassis so as to make yarns corresponding to each weaver (3) mutually weave into a three-dimensional fabric. According to the present invention, each weaver moves on the knitting machine base under the effect of the knitting machine chassis so as to make the yarns corresponding to each weaver mutually weave into the three-dimensional fabric, the knitting machine chassis is arranged on the knitting machine base through a plurality of support pipes, the yarn starts from the yarn shaft, penetrates through the yarn pipe, passes through the weaving arm, and arrives at the weaving surface position on the top portion of the weaving arm, the weavers perform the cross movement in the knitting machine chassis, the yarn shaft on the lower portion shuttles back and forth below the chassis, and the weaving arms on the upper portion are staggered above the chassis so as to achieve the three-dimensional knitting. The three-dimensional automatic knitting machine has characteristics of simple structure and significant effect, and is suitable for promotional use.

Description

technical field [0001] The invention relates to a three-dimensional automatic weaving machine in the field of textile machinery. Background technique [0002] It has been 30 years since the three-dimensional braided composite material was proposed and applied, and it has been introduced to China for 20 years. It has important applications in aerospace and other fields, for example, the Shenzhou 9 spaceship is an example. However, for a long time, three-dimensional weaving has been carried out in a semi-mechanical and semi-manual way, which makes the cost of three-dimensional weaving high and slow, which directly affects the wide application of three-dimensional weaving. [0003] In practical engineering applications, the vast majority of composite prefabricated parts are not regular structural parts with equal cross-sections, but special-shaped structural parts whose cross-sectional size gradually increases along the length direction, such as wind turbine blades, radar rado...
