Description

Technical Field

[0001] This utility model relates to the field of fine grinding equipment technology, specifically a centering fine grinding device for metal yarn tubes. Background Technology

[0002] Textile machinery refers to the various mechanical equipment needed to process natural or chemical fibers into textiles. While machinery for producing chemical fibers encompasses various chemical processing machines, it is now considered an extension of textile machinery and falls under a broader definition. The processes required to process different fibers such as cotton, linen, silk, and wool into textiles vary, and some are entirely different, thus requiring a wide variety of machines. Textile machinery is typically classified according to production processes, including: spinning equipment, weaving equipment, dyeing and finishing equipment, chemical fiber spinning equipment, silk reeling equipment, and nonwoven fabric equipment. Spinning equipment is further divided into those processing short fibers and those processing long fibers. Cotton and cotton-type chemical fibers belong to the short fiber category, while wool, linen, silk, and their blended chemical fibers belong to the long fiber category. The processing procedures for these two types of fibers differ, and the equipment cannot be interchanged; however, the design principles of some machines are similar. Looms use two or more sets of right-angle interlacing... Looms are machines used to form fabrics from yarn. They can be classified in various ways, such as by fabric fiber (cotton looms, wool looms, burlap looms, silk looms, etc.) or by weft insertion method (shuttle looms and shuttleless looms). Yarn tubes are a crucial component in textile machinery, serving to wind the yarn. Currently, common yarn tubes are made of plastic, suitable for most types of yarn and highly versatile. However, many types of specialty yarns also exist in the textile industry. Specialty yarns are those with unique structures and appearances obtained by processing fibers or yarns using special raw materials, equipment, or processes during spinning and yarn making, such as silk yarn. Because these yarns are finer and of higher quality, winding them with common plastic yarn tubes can cause snagging. Therefore, these yarns are generally wound using metal yarn tubes.

[0003] Currently, common metal yarn tubes generally require fine grinding of their outer surface. However, the common fine grinding equipment can only perform fine grinding on cylindrical shapes and is not suitable for fine grinding of conical tubes with different diameters at both ends. Therefore, we propose a centering fine grinding device for metal yarn tubes. Utility Model Content
