Embodiment Construction
[0028] see figure 1 , is a schematic structural view of the first embodiment of the split yarn carrier provided by the present invention, the split yarn carrier includes a yarn storage device 1 and a length compensation device 2 connected in series, in this embodiment:
[0029] The yarn storage device 1 is a frame-type rectangular yarn storage device, which has an outer frame 11 (both ends can be flat, round or pointed) and a rectangular inner frame 12. The inner frame 12 is wound with yarn. The shaft 16 in the length direction of the outer frame 11 rotates relative to the outer frame 11, and the yarn 13 on the inner frame 12 is used for weaving the preform (not shown) after passing through the yarn release hole (not shown) at one end of the outer frame 11. shown); the frame-type rectangular yarn storage device is provided with a limit mechanism 14 between the inner frame 12 and the outer frame 11, and the limit mechanism 14 can make the inner frame 12 be restricted from rotat...

The invention provides a split-type yarn carrying device comprising a yarn storage device and a length compensating device, which are serially connected with each other, wherein the length compensating device is connected to a yarn carrying movement component on a platform. The yarn storage device is preferably a frame yarn storage device, the frame yarn storage device is provided with an outer frame and an inner frame, yarns are wound on the inner frame, the inner frame can rotate relative to the outer frame, and the yarns on the inner frame penetrate through a yarn uncoiling hole in one end of the outer frame for weaving a preformed element. The length compensating device is preferably a scroll-type rope pulling device, the scroll-type rope pulling device is composed of a volute spiral spring and a foldable digging rope driven by the volute spiral spring, and the free end of the digging rope is connected with the yarn storage device. According to the split-type yarn carrying device, the yarn storage device and the length compensating device can be separately arranged, the structure of the yarn carrying device is very simple, the mechanism complexity is reduced and the failure rate is greatly reduced as well; and more importantly, compared with the existing mechanism, the digging rope is used for replacing repeatedly winding yarns, so that the yarns can not be damaged due to repeated friction, and further the quality and performance of the textile are guaranteed.
Description
technical field [0001] The invention relates to a yarn carrier used in a fiber weaving process, in particular to a yarn carrier used for a three-dimensional knitting machine with a large platform and a large depth. Background technique [0002] Three-dimensional weaving technology is an important way to prepare composite materials, especially advanced fiber-reinforced composite material preforms. application. [0003] However, due to the limitation of the form and principle of the three-dimensional knitting manufacturing equipment, whether it is four-step knitting or rotary knitting, there is a large range of movement of the yarn carrier of the knitting machine on the table. This brings about some problems that 2D knitting machines do not have: [0004] One is that due to the movement of the yarn carrier on the table, for example, when it is directly below the forming point from the edge of the table to the center of the table, the fiber length changes greatly; [0005] S...
