Embodiment Construction

[0013] Such as figure 1 As shown, a yarn carrier suitable for three-dimensional weaving and binding yarn control includes a bracket 1, and a yarn carrier tube 9 is movably installed on the bracket 1 through a yarn carrier base 8, and is sequentially connected with the yarn carrier base 8 There are buckle 6, connecting buckle 7, pull buckle 5, pilot conductor 4 and spring 2; wherein the base 8 of the yarn carrier is provided with a slot 10, and the buckle 6 can be located in the slot to prevent the yarn-carrying drum 9 from rotating. The outer peripheral surface of the pilot conductor 4 is fitted with a coil 3 .

[0014] Its movement process is: when the coil 3 is not energized, due to the effect of the spring 2, the buckle 6 is pushed into the slot 10 of the base 8 of the yarn carrier to limit its rotation. When the coil 3 is energized, the pilot conductor 4 will be attracted upwards, thereby driving the pull buckle 5, thereby pulling one end of the connecting buckle 7, so th...

Abstract

The invention belongs to the technical field of three-dimensional weaving binding yarns, and specifically relates to a yarn carrier and a feedback system suitable for controlling three-dimensional weaving binding yarns, including a support, on which a yarn carrying cylinder is movably installed through the base of the yarn carrying device, and is connected with the yarn carrying device. The base of the yarn device is sequentially connected with buckles, connecting buckles, pull buckles, pilots and springs; the base of the yarn carrier is provided with a card slot, and the buckle can be located in the slot to prevent the yarn carrying drum from rotating. Coils are matched and connected to the peripheral surface of the body. The invention controls the tightening and loosening of the yarn carrier carrying the bundled yarn through a feedback system, thereby realizing the automatic adjustment function of the tension and adapting to the requirements of the weaving working condition.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional weaving binding yarns, and in particular relates to a yarn carrier feedback system suitable for controlling three-dimensional weaving binding yarns. Background technique [0002] Fiber composite materials have the characteristics of high specific strength and high specific modulus. In recent years, the structural parts prepared from this material have been widely used in the fields of aerospace, automobile and marine equipment. For structural parts based on such materials, it is usually necessary to combine high-performance fibers into fiber reinforcements through a specific process. After the target geometry is formed, resin is injected into the reinforcements. After sufficient bonding, the final structural parts are obtained. Among the various technologies for preparing reinforcements, the three-dimensional weaving method has unique advantages, such as binding yarns that bind multiple...
