spinneret hole of various hole shape for spinning machine line

The spinneret is one of the important parts of the spinning machine. Its function is to transform the viscous polymer melt or solution through the micropores into a trickle with a specific cross-section, which is solidified by a solidification medium or a solidification bath. And forming a thread. In the spinning process, the spinneret will be blocked by mechanical impurities, carbon fiber, gel, etc., the spinneret hole, when the spinneret hole is partially blocked, the spinning solution will overflow on the outer surface of the spinneret/plate, resulting in the original filament The size is uneven and there are problems such as fineness and hairiness. When the spinneret hole is completely blocked, it will greatly increase the rate of fiber breakage, which has a great impact on the fiber quality, so the spinneret must be cleaned regularly.
Many factories now use ultrasonic cleaning machines to clean the spinneret. Ultrasonic cleaning is a cleaning method that is widely used in the industry and has a good effect. Its working principle is that when the ultrasonic is propagated in the cleaning liquid, the tiny bubbles in the cleaning liquid are in the sound field. Vibration occurs under the action. When the sound pressure reaches a certain value, the bubble will increase rapidly, and then the shock wave can reach thousands of atmospheres when it closes and bursts. The shock wave reduces the adhesion between the stain and the cleaned workpiece and can destroy insoluble stains. And make them dispersed in the cleaning liquid, so as to achieve the purpose of cleaning. Although the bursting energy of the bubbles is very high, because the volume of each bubble is very small, there will be no mechanical damage and obvious temperature rise for the workpiece.
