[0002] High-count blended yarn, simply referred to as high-count yarn, is high-quality yarn with higher yarn count in the field of textile. In the process of processing and production, high-count yarn needs to be processed into a roll by winding equipment and winding drum. As the carrier of yarn winding, the winding drum is usually made of durable material, which facilitates smooth winding of yarn and forms a good winding shape.

[0003] The existing blended yarn winding drum generally adopts a cylindrical structure or a conical structure when in use. However, the internal diameter of the winding drum with these two structures is usually fixed, which leads to the fact that they must match a winding shaft with a specific diameter to smoothly perform the winding operation. Since the internal diameter of the winding drum lacks the ability to flexibly adjust according to the diameter of the winding shaft, it is limited in actual application and lacks flexibility and versatility in use.

The two elastic sheets are bent to the same degree to control the internal diameter of the winding drum body. The winding drum body has sufficient contact area with the corresponding winding shaft, ensuring that the winding drum body is stable enough during winding and is not prone to falling. The size of the internal diameter of the winding drum body is indirectly changed by the bending degree of the elastic sheets. The winding drum body can be used on winding shafts with different diameters, improving the flexibility and versatility of the winding drum body.

[0006] In at least some embodiments,

[0007] The diameter of the locking screw hole matches the diameter of the limiting sliding groove; a locking bolt is mounted in the locking screw hole.

[0008] In at least some embodiments,

[0009] The locking bolt is also connected with the limiting sliding plate through the limiting sliding groove; a limiting washer is fixedly mounted on the circumferential outer wall of the locking bolt.
