Problems solved by technology

The yarn carrier of the determinant three-dimensional knitting machine operates in the form of a whole row or a whole column, and a single yarn carrier cannot move freely. Therefore, when the cross-sectional area of ​​the three-dimensional weaving prefab changes, it needs to be moved out of or added to the knitting area in a timely manner. yarn is more difficult

Embodiment Construction

[0024] The embodiments of the present invention will be further described below in conjunction with the drawings.

[0025] The overall picture of the three-dimensional braiding equipment is as figure 1 Shown. In the overall view, 1 is a three-dimensional braiding preform, 2 is a forming device, 3 is a knitting yarn, 4 is a gear-type active yarn carrier, and 5 is a rack-type knitting chassis. The gear-type active yarn carrier 4 is equipped with four DC motors, and each DC motor drives a pair of gears respectively, and there are a total of four pairs of gears. Each pair of gears are coaxial, with two DC motors in the X-axis direction and two DC motors in the Y-axis direction. In this way, the movement in each dimension is powered by two DC motors, and the gear-type active yarn carrier 4 is directly placed on the chassis composed of racks, and the two sets of racks on the chassis are arranged at equal intervals.

[0026] The knitting yarns are carried by the yarn carrier and arrange...

Abstract

The invention relates to three-dimensional knitting equipment which comprises a three-dimensional knitting preformed part, a forming device, a gear type initiative yarn carrier and a rack type knitting base plate. A gear on the gear type initiative yarn carrier is driven by a direct-current motor and meshed with a rack on the knitting base plate to enable the gear type initiative yarn carrier to operate on the base plate so as to drive knitting yarns to complete knitting of the three-dimensional knitting preformed part. The three-dimensional knitting equipment is provided with the direct-current motor which provides a driving force for the yarn carrier, and accordingly movement of the gear type initiative yarn carrier is improved, and the problems of yarn reduction and addition for the special-shaped three-dimensional knitting preformed part can be solved. Further, the three-dimensional knitting equipment is applicable to preparation of various three-dimensional knitting preformed parts.

Description

Technical field [0001] The invention relates to the technical field of three-dimensional three-dimensional weaving, in particular to a three-dimensional three-dimensional weaving equipment. Background technique [0002] Three-dimensional overall weaving technology is a high-tech textile technology developed in the 1980s, which has the characteristics of one-time weaving of special-shaped parts. During the knitting process, all the yarns participate in the weaving at the same time, and each yarn moves according to a certain law, thereby interweaving each other to form a three-dimensional overall fabric. This kind of reinforced composite material has the characteristics of light weight, no delamination, high strength, good overall performance and flexible structural design, which provides broad prospects for composite materials to be used in load-bearing structures. It has been used in aerospace, aviation, transportation, chemical engineering , Sports, medical and other fields hav...
