Description

Technical Field

[0001] The utility model belongs to the technical field of yarn separation of warping machines, in particular to a double-suction-nozzle yarn separation device. Background Art

[0002] Yarn separation technology is a very important technical content in the warp drawing machine. Yarn separation requires the process of separating independent yarns one by one in the yarn layer. The main problems with existing yarn separation are the occurrence of double yarns or unstable yarn absorption during the yarn separation process. Specifically, double yarn refers to the occurrence of two yarns after yarn separation, which makes it impossible to enter the textile link later. Another reason for unstable yarn absorption is that different thicknesses of yarns will appear on one yarn layer due to different process effect requirements, that is, the gap for absorbing the yarn will be too large or too small relative to the yarn. If the yarn is too large, it cannot be sucked into the suction nozzle, resulting in yarn falling. Although the yarn is too small, it can be sucked into the suction nozzle, the matching area is small, resulting in yarn falling or shaking. Utility Model Content
