Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber production equipment, in particular to a composite spinning device. Background Art

[0002] Composite spinning refers to a spinning method that prepares fibers by passing two or more spinning fluids of different chemical compositions or concentrations through a spinneret with a special distribution system at the same time. For composite spinning, due to the different melting points of its components and the different viscosities of the molten fluids, different melting temperatures are required during the spinning process. Different raw materials must be heated separately to obtain composite fibers that meet the multifunctional goals. The composite spinning boxes in the prior art are mostly two-component composite spinning boxes, such as a composite spinning device disclosed in Chinese patent CN116463742A, which includes a composite box body B, a connecting frame is symmetrically fixedly installed at the front end of the composite box body B, and a composite box body A is fixedly installed at the front end of the connecting frame. The composite box body B includes a first box cover, a melt B inlet, a melt B connecting pipe, a first box body, a melt B metering pump, a melt B branch pipe, a melt B distribution block and a first connecting pipe. The first box cover is fixedly installed on the top of the first box body, the melt B distribution block is fixedly installed on the inner bottom end of the first box body, the first connecting pipe is fixedly installed on the top of the melt B distribution block, the melt B inlet is fixedly installed on the top of the first connecting pipe, and the melt B branch pipes are fixedly installed on both sides of the melt B distribution block. When the aforementioned composite spinning box is in use, the composite box B and the connecting frame are combined and arranged, and the composite box B and the connecting frame are arranged in a separated manner, so that the composite box B and the connecting frame are not affected by each other's temperature when transmitting the spinning. At the same time, the melt B connecting tube and the melt A connecting tube inside the composite box B and the connecting frame adopt a counter-transmission method, so that the two types of spinning can be concentratedly transported to the spinning assembly inside the composite box, and the spinning can be centrally mixed and transmitted. However, the aforementioned prior art only realizes the preparation of two-component fibers, and, taking the inflow channel of solution B as an example, the lengths of multiple connecting tubes are different. For large-scale spinning equipment, the flow rates that finally flow into multiple spinning assemblies are different, which will cause the component contents of the mixed fibers extruded by multiple spinning assemblies to be slightly different, and finally affect the quality consistency of the composite spinning; in addition, the structure of the aforementioned composite spinning box can realize composite spinning of three components at most, but cannot realize mixed spinning of four or more components.

[0003] In view of this, the utility model provides a composite spinning device, which can realize the mixed spinning of two or more raw materials with large differences in melting temperatures, and the flow rate of the same raw materials flowing into the blending component chamber is the same, thereby ensuring the quality consistency of the mixed spinning and higher quality of the finished product.
