[0003] And the spinneret acts as the actual filament-forming element in the spinning machine for the production of man-made fibers, both in melt spinning and in dry and wet spinning; the spinneret is usually a round or square plate made of glass, metal or ceramic with a number of nozzle openings of the same size. They divide the spinning mass provided by the spinning pump at a constant pressure and per unit time into fine spinning melt or spinning solution jets. These are solidified into filaments by a subsequent chemical or physical post-treatment method, depending on the specific spinning process.
[0004] However, the existing spinnerets for preparing modified biomass fibers have poor shaping effects and insufficient molding degree, resulting in the ejected fiber filaments having an overly tight structure and insufficient fluffiness, resulting in low quality of the molded fiber filaments.

[0024] In order to facilitate the delivery of raw materials, please refer to Figure 2 The material collecting mechanism 2 includes a plurality of feed bins 21 , the upper ends of the outer surfaces of the plurality of feed bins 21 are provided with feed ports 22 communicating with the outside, and the bottom walls of the inner cavities of the plurality of feed bins 21 are provided with discharge holes 23 .
[0025] After the raw materials are put into the inner cavity of the feed port 22, the raw materials will flow downward through the inner cavity of the feed hole 23 to the inner cavity of the rough feed hole 32, thereby avoiding the spillage of the raw materials when the raw materials are put into the feed port.
[0026] In order to achieve the purpose of multiple shaping of the melt, see Figure 2 The feeding mechanism 3 includes a connecting plate 31, and a plurality of groups of coarse feeding holes 32 are provided in a circular array on the upper end of the outer surface of the connecting plate 31, and a plurality of fine feeding holes 33 communicating with the outside are provided on the bottom walls of the inner cavities of the plurality of coarse feeding holes 32. The upper end of the outer surface of the connecting plate 31 is fixedly connected to the lower ends of the outer surfaces of the plurality of feed bins 21, and the plurality of groups of coarse feeding holes 32 are communicated with the inner cavities of the plurality of feed holes 23.
[0027] After the put-in raw materials flow through the inner cavity of the discharge hole 23 to the inner cavities of the several feeding mechanisms 3, the raw materials are transported step by step through the inner cavities of the coarse feeding hole 1 32 and the fine feeding hole 2 33, so that the raw materials can be shaped multiple times while facilitating the transportation and shaping of the thickness of the final formed fiber filaments.
[0028] For the purpose of making the solution more ductile, see Figure 3 The extended bend pipe 4 is spirally shaped, the upper outer surface of the extended bend pipe 4 is fixedly connected to the lower inner cavity of the corresponding fine feed hole 33, and the lower outer surface of the extended bend pipe 4 is fixedly connected to the upper inner cavity of the corresponding spinneret hole 11.
[0029] The melt of the finally formed fiber filaments can be transported again so that the melt can enhance its own ductility while flowing in the inner cavity of the extension elbow 4, making the fiber filaments softer after being ejected.

[0034] The working principle of the utility model is as follows: first, the device is placed in a suitable position by holding the two handles 52, and then the raw materials are put into the inner cavity of the feed port 22. The raw materials will flow downward through the inner cavity of the discharge hole 23 to the inner cavity of the coarse feed hole 32, and then the raw materials will be transported step by step through the inner cavities of the coarse feed hole 32 and the fine feed hole 33. Finally, the raw materials will be transported in a spiral manner through the extension bend 4 again to make the formed raw materials more ductile, until they are ejected through the spinneret hole 11 to form.
