Abstract
Description
Technical Field
[0001] This utility model relates to the field of twisting spindle technology, and in particular to a twisting spindle with a cat's eye support structure. Background Technology
[0002] After being twisted, filaments exhibit different textures in textiles. Twisted chemical fiber filaments can be made into yarns with various styles and wide applications, such as sewing thread, embroidery thread, bag thread, zipper thread, and knitting yarn. Fiber twisting is mostly done by twisting machines, and the twisting spindle is a key component of the twisting machine.
[0003] The existing spindle structure suffers from high vibration, requires oil changes and maintenance, and has a low rotation speed. In particular, the belt drive has a large speed difference, poor yarn consistency, and low quality. In addition, the large gap between the yarn tube and the spindle results in high vibration and low speed. The lack of direct motor drive makes bearing maintenance inconvenient, and the low rotation speed and high vibration make it difficult to spin high-quality yarn. Utility Model Content
