[0002] A spinning needle is a device that can process spinning into a specific shape. At present, a spinning needle can only process a specific shape of spinning. If it is necessary to continuously process spinning of different shapes, it is necessary to constantly change the corresponding shape. Spinning needles, which make the replacement frequency of spinning needles high, the efficiency of spinning processing is low, and for the current preparation of core-shell spinning needles, the function is single, and there is a lack of multi-functional spinning needles

The invention discloses a spinning needle and a spinning device, and belongs to the technical field of spinning. The spinning needle comprises a feeding device, a flow guiding device and a forming device, and the feeding device is provided with a shell material channel; the flow guiding device is provided with a nuclear material channel; the forming device comprises two forming discs, each formingdisc is provided with a plurality of forming openings with different shapes, each forming disc can rotate so as to combine the forming opening in one forming disc with the forming opening in the other forming disc to form a combined opening; and the spinning device comprises any one spinning needle. In the working process, the two forming openings are in butt joint to be combined into the combined opening, core-shell spun yarns flowing out of the feeding device enters the combined opening, the core-shell spun yarns are machined into the shape of the combined opening through the combined opening, the forming discs are rotated, the combined openings in other shapes are formed for continuous machining, and the defect that the spinning needle is frequently replaced is overcome. In addition, the core-shell spun yarns with core shift, curve shapes, hollow structures or spiral core structures can further be prepared.
Description
technical field [0001] The invention is used in the technical field of spinning, and in particular relates to a spinning needle and a spinning device. Background technique [0002] A spinning needle is a device that can process spinning into a specific shape. At present, a spinning needle can only process a specific shape of spinning. If it is necessary to continuously process spinning of different shapes, it is necessary to constantly change the corresponding shape. Spinning needles, the replacement frequency of spinning needles is high, the efficiency of spinning processing is low, and the current preparation of core-shell spinning needles has a single function and lacks multifunctional spinning needles. Contents of the invention [0003] The object of the present invention is to solve at least one of the technical problems in the prior art, and provide a spinning needle and a spinning device, which can reduce the replacement frequency of the spinning needle and improve ...
