Technical Field

[0001] The utility model relates to the technical field of yarn production equipment, and specifically discloses a shearing device for yarn production. Background Art

[0002] Yarn is a linear material made of natural fibers or chemical fibers such as cotton, linen, wool, and silk through textile processing. It is widely used in daily life and industrial production. Yarn cutting equipment is an important equipment in the yarn production process. It can cut continuous yarn and facilitate independent winding of yarn. Chinese patent No. CN 217648457U discloses a yarn cutting device for yarn production, including a bottom plate, fixed frames are arranged on the left and right sides of the top of the bottom plate, pulleys are arranged on the fixed frames, a fixed plate is arranged at the rear end of the top of the bottom plate, a connecting plate is arranged on the front of the fixing plate, a wire pressing mechanism is arranged between the connecting plate and the bottom plate, a wire cutting assembly is also arranged at the bottom of the connecting plate, and a waste box is movably arranged in the inner cavity of the bottom plate. The yarn cutting device for yarn production can quickly and automatically cut the yarn by first passing the yarn end through the bottom of two pulleys, pressing and fixing the two ends of the yarn by the wire pressing mechanism, and then controlling the wire cutting assembly. During the cutting process, the yarn is in a taut state, and the shearing effect is more ideal. At the same time, it is not easy for the yarn to be entangled and knotted, which makes the device more convenient and practical, and greatly enhances its working efficiency.

Therefore, in order to solve the above-mentioned problems, the utility model proposes a shearing device for yarn production. Utility Model Content
