BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Attached Figure 1 It is a structural schematic diagram of the spinneret of the utility model. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] As attached Figure 1 The reinforced spinneret structure of a spinning assembly comprises a spinneret 1, on which a plurality of spinneret holes 2 are disposed, and the discharge surface of the spinneret 1 corresponds to the discharge ports of the spinneret holes 2. At least one reinforcing rib 3 is disposed on the discharge surface of the spinneret 1, and the strength of the surface of the spinneret 1 is improved by the reinforcing rib 3, thereby enhancing the impact resistance of the spinneret 1, so that the spinneret 1 is not prone to local bulging under the impact of the spinning melt.

[0015] The reinforcing ribs 3 include interconnected straight ribs 4 and curved ribs 5, wherein the straight ribs 4 extend in the radial direction of the spinneret 1, and the curved ribs 5 extend in the circumferential direction of the spinneret 1. The straight ribs 4 and the curved ribs 5 extend in different directions, and compared with ribs in a single direction, the ribs in different extending directions cooperate with each other, which can more effectively enhance the impact resistance of the spinneret 1.

[0016] As attached Figure 1 As shown in the figure, there are multiple reinforcing ribs 3 on the discharge surface of the spinneret 1, and the straight ribs 4 of the multiple reinforcing ribs 3 cooperate with each other to divide the discharge surface of the spinneret 1 into multiple fan-shaped spinning areas 6, that is, the straight ribs 4 on two adjacent reinforcing ribs 3 are sandwiched on both sides of the fan-shaped spinning area 6. The spinneret holes 2 are correspondingly opened in the fan-shaped spinning area 6, so that the spinneret holes 2 and the straight ribs 4 are staggered with each other.

[0017] One end of the curved rib 5 is connected to the straight rib 4 , and the other end of the curved rib 5 extends in an arc direction toward the adjacent fan-shaped spinning area 6 to enhance the plate strength of the fan-shaped spinning area 6 .

[0018] The curved ribs 5 extend in an arc direction along the outer edge of the fan-shaped spinning area 6. The curved ribs 5 and the straight ribs 4 cooperate to form a semi-enclosed structure to semi-enclose the adjacent fan-shaped spinning area 6. The curved ribs 5 can increase the plate strength of the fan-shaped spinning area 6 without interfering with the inner spinning holes 2 of the fan-shaped spinning area 6, so that the layout position of the reinforcing ribs 3 is more reasonable.

[0019] The arc angle of the curved rib 5 is greater than or equal to half of the arc angle of the fan-shaped spinning area 6 surrounded by it. Figure 1 In one embodiment shown in , the arc angle of the fan-shaped spinning area 6 is 120 degrees, and the arc angle of the curved rib 5 is greater than or equal to 60 degrees. The curved rib 5 covers at least half of the fan-shaped spinning area 6, so that the curved rib 5 can better strengthen the plate strength of the fan-shaped spinning area 6.

[0020] The ends of the curved ribs 5 are connected to the ends of the straight ribs 4 , and the connected curved ribs 5 and the straight ribs 4 are in an angled shape as a whole to semi-enclose the fan-shaped spinning area 6 .

[0021] The plurality of reinforcing ribs 3 on the spinneret 1 are arranged at equal angles in the circumferential direction, so that the position distribution of the reinforcing ribs 3 is more uniform and reasonable.

[0022] In the utility model, the structural strength of the spinneret 1 is improved by the reinforcing ribs 3 semi-enclosed in the fan-shaped spinning area 6, so that the spinneret 1 is not prone to local bulging under the impact of the spinning melt, and the semi-enclosed reinforcing ribs 3 are not easy to interfere with the spinneret holes 2, and it is also more convenient to clean the discharge surface of the spinneret 1.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
