Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to an adjustable yarn guide hook. Background Art

[0002] The yarn guide hook is installed above the key of the ring spinning machine to guide the yarn output from the front roller to cooperate with the wire ring for twisting. The center position of the yarn guide hook hole must be on the center line of the key. The twist added by the wire ring to the yarn is transmitted to the upper spinning section through the yarn guide hook until it reaches the front roller jaws. Since the yarn has an arc around the yarn guide hook, the twist transmission is blocked and twist is generated on the spinning section. The yarn guide hook rises and falls with the rise and fall of the bobbin winding to stabilize the balloon height and spinning tension.

[0003] The winding machine does not have a balloon breaker, and only has a yarn guide hook to control the yarn path. Generally, for high-count yarns and small bobbins, the rewinding tension will not be too large, and the balloon shape is relatively stable; but for low-count yarns and large bobbins, the rewinding tension becomes larger, and the balloon shape is difficult to control. For bobbins with high tension and difficult-to-control balloon shape, there is a risk of entanglement between the bobbins of two adjacent spindles. In order to reduce the risk of entanglement, spindles are generally placed at intervals, which greatly reduces the utilization rate of the machine and also greatly reduces efficiency. At the same time, the tension is high and the unstable balloon shape will cause the yarn breakage to increase. For this reason, we propose an adjustable yarn guide hook. Utility Model Content
