The invention discloses a
spinning frame
yarn broken end detection device. The device comprises a fixing frame, warp beams are rotatably connected to the inner walls of the two sides of the fixing frame, a detection frame is arranged on the fixing frame, an installation frame is arranged on the detection frame, a driving
assembly is arranged on the installation frame, a detection
assembly is arranged on the driving
assembly, and the detection assembly is driven to do reciprocated motion in the axial direction of the warp beams. The detection assembly comprises an
infrared emitter, the infraredemitter is connected with the driving assembly through an adjusting assembly, and the
infrared emitter is driven to conduct pitching adjustment. According to the detection device, the reciprocating detection assembly is adopted, all-position detection
processing can be conducted on broken
yarn wound and bulged on the warp beams, meanwhile, the detection angle of the detection device can be adjusted in cooperation with an adjusting assembly, it is guaranteed that the detection angle of the detection device can be matched with the winding thickness of the
yarn on the warp beams in real time, and therefore, the detection accuracy of the end yarn on the warp beams is improved.
