Spinning frame yarn broken end detection device

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of textile processing, in particular to a yarn break detection device for spinning frame. Background technique [0002] In the sizing production process, the warp beam is unwound according to the speed set by the process, and the warp yarn is unwound from the warp beam, and then enters the slurry pot to be impregnated with the size liquid, and the size liquid penetrates into the interior of the yarn through the pressure of the pressure roller , and then separate stranding in the dry stranding area, and finally wind up on the pulp shaft through the take-up roller at the headstock, and the yarn on the warp beam is generally at a speed of 10m / min-100m / min during the unwinding process. [0003] At present, the method of detecting whether the yarn is broken or not generally adopts the method of manual visual inspection. During the sizing production process, the operator must continuously check whether the warp ya...

Problems solved by technology

[0003] At present, the method of detecting whether the yarn is broken or not generally adopts the method of manual visual inspection. During the sizing production process, the operator must continuously check whether the warp yarn on the warp beam is broken or entangled, so as to ensure the quality of the sizing beam. If the roving inspection of the locomotive operator is not timely, the yarn on the warp beam is easy to be wound on the warp beam after the end is broken, and the nearby yarns are involved together, which seriously affects the production quality of sizing
