Description

TECHNICAL FIELD

[0001] The utility model belongs to the yarn sizing machine technical field, especially is related to a single yarn sizing machine yarn winding device. BACKGROUND

[0002] Yarn sizing is the processing technology commonly used in the textile industry to improve the weavability and durability of yarn. During the sizing process, the sizing machine immerses the yarn in a sizing tank. Then, the yarn is sent to a drying device to dry the sizing on the yarn. Finally, the processed yarn is rewound onto a winding roller. During the winding process, the operator needs to wrap the yarn around the winding roller several times to secure it. Then, the winding roller is clamped into a cantilever that controls the rotation of the winding roller. During this process, if the number of wraps around the winding roller is too small, it will not effectively secure the yarn, which can cause the yarn to fall off during the winding process. On the other hand, if the yarn is wrapped too many times, it will waste time. Moreover, to control the rotation of the winding roller, two cantilevers are used to clamp the winding roller. The cantilever near the machine body is equipped with a synchronous motor, and the other end is equipped with a structure to clamp the winding roller. The operator needs to first expand the gap between the two cantilevers by bending them outward, then align the two cantilevers with the pre-set position, and finally clamp them. This increases the labor intensity of the operator and makes it difficult to align the winding roller with the pre-set position, causing the winding roller to vibrate during work. Additionally, the clamping transmission method can cause relative movement at the connection between the winding roller and the cantilever, which can cause the yarn to loosen during the initial stage.

[0036] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0037] The yarn winding mechanism of the yarn winder, comprising two cantilever arms 1, two cantilevers 1 ends are respectively equipped with shaft 11, a cylindrical winding roller 4 is arranged between two shafts 11.
