[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. The spinning needle includes a feeding device, a flow guiding device and a forming device. The feeding device has a shell material channel; the flow guiding device has a core material channel, and the forming device includes two Each forming disc has a plurality of forming openings with different shapes, and each forming disc can be rotated to combine the forming opening on one of the forming discs with the forming opening on the other forming disc to form a combined opening. The filament device includes any of the spinning needles above. During the working process, the two forming ports are butted and combined to form a combined port, the core-shell spinning flowing out of the feeding device enters the combined port, the core-shell spinning is processed into the shape of the combined port through the combined port, and the forming disc is rotated. Combining ports of other shapes can continue to be processed, which reduces the disadvantages of frequent replacement of spinning needles. In addition, core-shell spinning with eccentric, curved, hollow or helical core structures can also be prepared. The present invention is used for spinning technology field.
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 ...
