Embodiment 2:

[0025] See also Figure 1~Figure 4 , the utility model is a spinning assembly for composite fibers of special structure. Compared with the first embodiment, the present embodiment further includes: the outer shell 1 and the inner shell 6 are both slidably provided with an extrusion piece 7; the extrusion piece 7 includes a first metal plate 71 that is plugged and fixedly installed at the bottom of the piston rod of the first cylinder 32; a first sealing ring 72 with a sealing function is adhesively fixed to the outer ring side of the first metal plate 71; the top of the first metal plate 71 is symmetrically distributed with first filter valve ports 73, and the first filter valve port 73 is connected to the quick connector 34 on the middle side of the top of the upper cover 2 through a telescopic tube.

[0026] A second metal plate 74 is inserted and fixedly installed at the bottom of the piston rod of the second cylinder 33; a second sealing ring 75 with sealing function is glued and fixed on the outer ring side of the second metal plate 74; second filter valve ports 76 are symmetrically distributed on the top of the second metal plate 74, and the second filter valve ports 76 are connected to the quick connector 34 on the outer side of the top of the upper cover 2 through a telescopic tube.

[0028] The working principle of the spinning assembly based on an improved special-shaped composite fiber is:

[0029] First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation;

[0030] Second, the staff connects the two sets of quick connectors 34 on the top of the upper cover 2 longitudinally to the first external melt equipment through pipelines, and connects the two sets of quick connectors 34 on the top of the upper cover 2 transversely to the second external melt equipment through pipelines, so that the two melts successively pass through the quick connectors 34 and their bottom telescopic tubes and the first filter valve port 73 and the second filter valve port 76 to enter the outer shell 1 and the inner shell 6.

[0031] Third, the staff then introduces the air source into the solenoid valve 31 through the external controller, and drives the first cylinder 32 and the second cylinder 33 to extend synchronously through the guiding effect of the solenoid valve 31. At this time, the first cylinder 32 and the second cylinder 33 respectively drive the first metal plate 71 and the second metal plate 74 to slide downward, so that the first sealing ring 72 and the second sealing ring 75 compress the internal space of the outer shell 1 and the inner shell 6 respectively, and then the melt flows downward along the flow channel set in the guide upper plate 4 under the action of pressure, and enters the oblique flow channel 51 and gathers at the diverter sphere 53 at the top of the slot flow channel 52. Due to the blocking effect of the diverter sphere 53, the two melts flow downward and compound together, and then spray out through the bottom of the slot flow channel 52 to form a composite melt thin flow containing two different components, and then it is shaped by external cooling and oiling equipment to finally form a special-shaped composite fiber.

[0032] The utility model provides a spinning assembly for composite fibers of special structures through improvement. By setting a double-flow channel structure of an outer shell 1 and an inner shell 6 and utilizing an extrusion piece 7 to increase the pressure of the assembly more smoothly, thereby reducing internal leakage of the extrusion piece 7, solving the problem of slow flow rate of the melt under normal pressure, and reducing the flow path of the melt, improving the smoothness of the melt flow, thereby reducing breakage and extending the service life of the assembly.
