Background
The spinning cap is a precise component on a chemical fiber spinning machine, also called a spinneret plate and a spinning head, and a large number of spinning holes with consistent size are arranged on the spinning cap. During spinning, the spinning solution or melt passes through these micropores and enters the coagulation bath or air in a trickle state, and is coagulated or cooled to form fibers. Spinnerets are an important component in the spinning industry that directly affects the quality of the finished yarn. During long-term operation of the spinneret cap, the spinneret holes are subject to defects such as blockage, erosion and the like, which seriously affect the fiber quality. Therefore, in the spinning industry, the detection of the spinneret orifices is of great significance both before and during use.
The existing detector is used for polishing the spinning caps from bottom to top, photographing and analyzing the whole spinning caps on the right upper side of the spinning caps, detecting personnel roughly judge whether the spinning caps are qualified or not on the whole according to the light transmission condition of each spinning hole on a photo, and only the photo can be observed after being amplified aiming at the spinning holes with abnormal light transmission, but the specific defect types cannot be determined by photographing the spinning holes with abnormal light transmission in a focusing mode one by one. The defects of the spinneret holes, such as erosion, cannot be repaired, and the defects of blockage, such as blockage, can be repaired by a conventional maintenance means. In addition, in order to improve the management level of the spinning caps, some enterprises can set unique identification codes on the spinning caps according to the specifications and the numbers of the spinning caps, and establish a detection archive database of the spinning caps according to the identification codes, and the existing detectors are also not provided with components for identifying the identification codes.
