Description

Technical Field

[0001] The present invention relates to the technical field of textile equipment, and in particular to a spindle flyer grinding device. Background Art

[0002] The flyer is a core component of spinning and winding in textile machinery. The grinding accuracy of the inner wall of its hollow tube and the outer wall of the flyer arm directly determines the quality of yarn formation and the life of the equipment. Currently, the industry generally uses manual operation to grind the flyer. The specific process is: the operator manually inserts a flexible grinding rope into the hollow tube of the flyer and controls the up and down movement and rotation of the grinding rope with a handheld tool to achieve the polishing of the inner wall. Manual control of the grinding rope's lifting speed and rotation frequency is uneven, which can easily lead to uneven polishing of the inner wall or excessive wear, affecting the dimensional accuracy of the flyer. To this end, we propose a flyer grinding device. Summary of the Invention
