Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a yarn feeding spindle. Background Technology

[0002] The yarn guide bobbin is a key component in textile machinery used to suspend the roving tube and achieve stable yarn traction, and is widely used in equipment such as spinning frames. Existing yarn guide bobbins have the following problems during use: On the one hand, the tension adjustment is not precise enough, and the coordination between the spring and the damping structure is not stable enough, resulting in large fluctuations in the yarn traction tension, which can easily lead to problems such as yarn breakage and yarn defects. On the other hand, the installation and positioning between the various components of the bobbin is not convenient. Some structures use fixed connections, which are not easy to disassemble and maintain. Moreover, the reliability of the support and positioning is insufficient. After long-term use, it is easy to shake due to wear, which affects the stability of yarn feeding. In addition, the connection strength and wear resistance of the screw and connecting parts need to be improved, which reduces the overall service life of the lifting spindle. Utility Model Content
