Description

Technical Field

[0001] This utility model relates to the field of yarn production technology, specifically a shearing device for yarn production. Background Technology

[0002] Yarn is a long, thin material formed by combining numerous fibers in a certain way and then twisting or otherwise treating them. These fibers can be natural fibers, such as cotton, wool, silk, and hemp, or chemical fibers, such as polyester, nylon, acrylic, and spandex. They can also be blends of natural and chemical fibers. In the yarn production process, the yarn needs to be cut. However, most existing cutting devices use two sharp blades to squeeze and cut the yarn. Moreover, the yarn is in a loose state during the cutting process, which can easily cause tangling and knotting. Furthermore, during the splicing operation, there is a risk of accidental injury from the cutting device's blades, which is very inconvenient. Utility Model Content
