The nozzle assembly of precision parts silk chemical fiber spinning machine, also known as the spinning head. The spinneret shape is generally hat shaped, circular or corrugated, there are many holes on the surface of the same size. In spinning, spinning solution or melt from these micropores by, trickle to squeeze into the coagulation bath or in the air, namely solidification and cooling into fibers. The spray head, distribution plate and filter material, etc.. The distribution plate is uniformly dispersed into a lot of small holes in the gel or melt. Filter used to filter waste. Component in the most important component of the wire, directly affect the quality of finished products. According to the different spinning method, three kinds of spinning, wet spinning and dry spinning were divided. Melt spinning spinneret is generally circular, it is also called the spinneret, there are rectangular. The circular spray wire plate is made of high temperature resistant stainless steel, the structure is simple and easy to manufacture. The pore diameter of the spray wire used for the melt spinning is related to the fiber variety and the spinning condition, the average diameter is 0.5 ~ 0.2 mm. Spinning hole number is generally dozens of holes, a palm hole, short fiber spinning holes generally up to 400 ~ 2000. Wet spray head mainly for the hat shaped, also known as the spray cap, there are disc shaped and plate (corrugated), with a strong corrosion resistance of gold platinum alloy or titanium, niobium, tantalum, stainless steel and other metal. In the spinning of the filament, the number of holes is less than that of the jet. The number of holes is 2 to 150 thousand, and the number of holes can be divided into a number of spray heads and the same piece of stainless steel. The aperture ratio of wet spinning jet head is smaller than that of the melt spinning, and the diameter of the hole is 0.05 ~ 0.1 mm. Commonly used dry spinning silk head (plate) is a cap and round two, the aperture is 0.16 ~ 0.07 mm, the number of holes is 300 ~ 1200, made of stainless steel or special alloy steel.
