[0002] The spinneret is a key component in the chemical fiber production process, and its performance directly affects the quality and production efficiency of the fiber. When producing ceramic fibers, a ceramic precursor melt or solution is injected into the spinneret, ejected through the spinneret, and solidified in the air to form fibers. The traditional spinneret design has jets arranged on the periphery of the spinneret or jets are provided on the periphery and center of the spinneret. However, this design cannot evenly blow air to each spinneret hole, resulting in poor uniformity and flexibility of the produced fibers, and the fibers are easy to stick to each other, and the spinneret is easy to clog. These problems limit the improvement of production efficiency and fiber quality. Electrospinning is the most effective way to produce uniform fibers, but the production equipment is small, and the output is low when mass-producing fibers, making it difficult to improve production efficiency.

[0017] The following is a specific description of the utility model.
[0018] Example 1
[0019] like Figure 1-Figure 3 As shown, this embodiment provides a square electrostatic melt-blowing spinneret; the electrostatic melt-blowing spinneret is divided into two main bodies, namely a glue injection plate 1 and an air injection plate 2, the upper layer is the glue injection plate 1, and the lower layer is the air injection plate 2;
[0020] The upper end face of the glue injection plate 1 is a glue injection end face, provided with a glue injection port 3, and the lower end face of the glue injection plate 1 is a spinning end face, provided with a spinning port 5; a glue outlet 4 is provided on the right side wall of the glue injection plate 1; a plurality of spinning ports 6 are evenly provided on the side wall of the gas injection plate 2, and all the spinning ports 6 are respectively connected to the same air pressure; the lower end face of the gas injection plate 2 is an air injection end face, provided with an air injection port 7, the cross section of which is annular, and each spinning port 5 is nested in an annular air injection port 7, the diameter of the spinning port 5 is 0.10 mm, and the diameter of the air injection port 7 is 3.55 mm;
[0021] Among them, the number of gas injection ports 6, spinnerets 5 and air jets 7 can be set according to actual production requirements. In the present embodiment, the gas injection ports 6 are evenly arranged on the front and rear end faces of the square gas injection plate 2, and the number of the front and rear gas injection ports is 7; the number of spinnerets 5 and air jets is 7, which are linearly and evenly arranged on the lower end face of the spinneret.
[0022] The working principle of this utility model:
[0023] When the utility model is in use, the glue injection port 3 is connected to the spinning solution storage tank through a pipeline, and the glue outlet 4 is connected to the recovery tank through a pipeline to discharge waste glue for easy collection and recovery, and all the air injection ports 6 are connected to the same air pressure; the spinning solution is ejected from the spinneret 5, and the air jet 7 simultaneously ejects a uniform high-speed airflow to quickly stretch the ejected fibers. Since each spinneret hole 5 is nested in the corresponding air jet 7, the ejected fibers are evenly pressurized and have a high degree of forming, so that fiber production with high uniformity and good softness can be achieved.
[0024] In summary, when the spinneret is used, the fibers ejected by the electrostatic field force are rapidly stretched and dropped to be collected by the uniform high-speed airflow ejected from the surrounding air jets. The ejected fibers have the properties of high uniformity and good softness.
