Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of yarn separation of a warp drawing machine, and in particular relates 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 problem with existing yarn separation is 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. Too large yarn cannot be sucked into the suction nozzle, resulting in yarn falling. Too small yarn can be sucked into the suction nozzle, but the matching area is small, resulting in yarn falling or shaking. Summary of the invention
