Description

Technical Field

[0001] The utility model relates to the technical field of textile, in particular to a yarn breaking mechanism of a warping machine. Background Art

[0002] Warping, as an important step in weaving, aims to wind a certain number of cheese yarns into a certain width in parallel according to the designed length and wind them onto a warping beam or a loom beam to prepare for the warp system of the fabric. In weaving production, the widely used warping methods can be divided into sectional warping and beam warping. During the warping process, the yarn needs to be wound around the warping beam. After the yarn winding is completed, it needs to be disconnected, and then the warping beam wound with the yarn is removed from the warping machine for subsequent process treatment.

[0003] After retrieval, a patent with the Chinese patent publication number CN221000013U discloses a yarn breaking mechanism of a warping machine, which mainly drives a cutting knife to cut the yarn under the action of a motor, a screw rod, a movable plate and a guide rod, thereby reducing the strength during cutting.

[0004] Comparing with the prior art in the related field, it can be seen that when using a cutting knife to cut the yarn, there is a lack of corresponding limiting devices for the yarn on both sides of the cutting position. The yarn has a certain tension during cutting. After cutting, the cut yarn will be scattered, which is not convenient for subsequent finishing production and slows down the production efficiency.
