Problems solved by technology
[0002] The existing three-dimensional loom tension device is a fixed shaft, and there is sliding friction between the yarn and the shaft, and the friction force is relatively large, so that the yarn tension is too large when the loom is beating up, and the yarn splits and hairs are serious, which is easy Frequent breaking of the yarn causes many defects on the fabric surface and affects production efficiency
[0003] The sliding friction between the traditional yarn guide rod and the yarn wears the yarn greatly, and makes the yarn tension uncontrollable. The yarn is easy to break when the loom is working. Due to the complex structure of the loom, it makes wiring difficult. , and there are many defects on the fabric surface, which affect the production efficiency of the loom and the quality of the fabric, making it difficult to give full play to the superiority of the loom

The invention relates to a tension control system of a three-dimensional loom, including a yarn tension adjusting and finishing device, a zero-damage yarn guide device and a positioning and tensioning device of a yarn bobbin, which are connected with yarn in sequence during the fabric manufacturing process. The tension adjusting and finishing device of the yarn bobbin changes the slip plane contact between a steel shaft and the yarn into rolling contact by utilizing the rotation of a bearing, the zero-damage yarn guide device reduces the friction by utilizing a miniature bearing, the positioning and tensioning device positions the yarn bobbin by a positioning device and provides enough friction to meet the tensioning requirement of the yarn, and the magnitude of the friction can be realized by slightly adjusting the angles and tightness at two lateral wings of the positioning device. The tension system is highly efficient, can greatly reduce the end breakage rate of the yarn, also haslow cost and is an effective tension control system.
Description
technical field [0001] The invention belongs to the technical field of textiles, in particular to a three-dimensional loom tension control system. Background technique [0002] The existing three-dimensional loom tension device is a fixed shaft, and there is sliding friction between the yarn and the shaft, and the friction force is relatively large, so that the yarn tension is too large when the loom is beating up, and the yarn splits and hairs are serious, which is easy The yarn is often broken, resulting in many defects on the fabric surface and affecting production efficiency. [0003] The sliding friction between the traditional yarn guide rod and the yarn wears the yarn greatly, and makes the yarn tension uncontrollable. The yarn is easy to break when the loom is working. Due to the complex structure of the loom, it makes wiring difficult. , and there are many defects on the fabric surface, which affect the production efficiency of the loom and the quality of the fabri...
