Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 6, the long fiber cotton spinneret plate with good shaping effect comprises a disc-shaped body, the body comprises a material plate 1 and a positioning plate 2, the material plate 2 is integrally formed at the inner ring of the material plate 1, the lower end of the positioning plate 2 and the lower end of the material plate 1 are located on the same plane, the upper end of the positioning plate 2 is lower than the upper end of the material plate 1, for convenience of understanding, the upper end of the positioning plate 2 refers to the upward end shown in fig. 1, and the lower end of the positioning plate 2 refers to the downward end shown in fig. 1.

Seted up a plurality of spinneret orifice 3 on flitch 1, spinneret orifice 3 uses the center pin of locating plate 2 to be the circumference array and arranges as the center, and both ends about flitch 1 are run through to spinneret orifice 3, and spinneret orifice 3's feed end is located the upper end of flitch 1, and spinneret orifice 3's feed end is equipped with the chamfer structure, and spinneret orifice 3's discharge end is located the lower extreme of flitch 1.

The cross section shape of the spinneret orifice 3 is enclosed by a first major arc 31, a first straight line 32, a second major arc 33 and a second straight line 34, namely, the cross section shape of the spinneret orifice 3 is dumbbell-shaped, the first straight line 32 is parallel to and equal to the second straight line 34, the first major arc 31 is equal to the second major arc 33, and the structure is designed to ensure that the spun fiber is not easy to break and has higher strength; the straight line that the centre of a circle of first major arc 31 and the centre of a circle of second major arc 33 are even and crossing with the center pin of locating plate 2 perpendicularly, and the scope of spinneret orifice 3 from its feed end to discharge end reduces gradually, and the design makes the greater pressure difference source of solution in the downthehole acquisition of jet-propelled like this to the dynamics that makes the jet-propelled silk is more even, obtains better moulding effect, just the utility model discloses after arranging the jet-propelled hole according to the geometry rule, spun cellosilk has better moulding effect.
