[0021] Example 1

[0022] like Figure 1 and Figure 2 A novel spinneret assembly holder is shown, comprising a conical plate 100, a circular transition plate 106 and a spinneret 114;

[0023] The contact surfaces of the conical plate 100 and the circular transition plate 106 are circularly provided with a plurality of conical plate openings 105 and a plurality of circular transition plate openings 108 used in conjunction with each other.

[0024] A circular collecting trough 116 is provided on one side of the spinneret 114 and is used in conjunction with a plurality of circular transition plate openings 108.

[0025] The other side of the spinneret 114 is provided with a circular spinneret hole 117 for use with the collecting trough 116.

[0026] A group of circular transition plate screw holes 107 are symmetrically arranged in the outer layer of the circular transition plate 106.

[0027] The outer layers of the conical plate 100 and the spinneret 114 are symmetrically provided with countersunk screw holes 101 and spinneret screw grooves 115 that cooperate with the circular transition plate screw holes 107.

[0028] The conical plate 100, the circular transition plate 106 and the spinneret 114 are fixed together by bolts 104 through the countersunk screw holes 101, the circular transition plate screw holes 107 and the spinneret screw grooves 115.

[0029] One side of the conical plate 100 is provided with a feed cover 102 covering a plurality of conical plate openings 105.

[0030] A feed port 103 is provided on one side of the symmetrical center line of the feed housing 102 .

[0031] The working principle is: stack the conical plate 100, the circular transition plate 106, and the spinneret 114 in sequence, and ensure that the countersunk screw hole 101, the circular transition plate screw hole 107, and the spinneret screw groove 115 correspond in vertical position. At this time, use the bolt 104 to fix the conical plate 100, the circular transition plate 106, and the spinneret 114 through the countersunk screw hole 101, the circular transition plate screw hole 107, and the spinneret screw groove 115. After assembly, the vertical positions of the conical plate material opening 105, the circular transition plate material opening 108, and the collecting trough 116 correspond.

[0032] Example 2

[0033] On the basis of the first embodiment, the novel spinneret assembly seat further includes at least two groups of arc-shaped limit plates 109 on the edge end surface of the circular transition plate 106, and circular plates 111 arranged on the surface of the circular transition plate 106 and respectively abutting against the inner walls of the two groups of arc-shaped limit plates 109, and circular filter holes 112 arranged in a circular shape in the circular plate 111 and used in conjunction with the circular transition plate material port 108 and the collecting trough 116, and circular plate limit screw holes 113 symmetrically arranged in the outer layer of the circular plate 111 and used in conjunction with the bolts 104;

[0034] Among them, the circular plate 111, the circular filter hole 112 and the circular plate limiting screw hole 113 are made of stainless steel in one piece. The one-piece hard structure provides stable support for the spinneret 114 to prevent extrusion deformation. At the same time, it is pressure-resistant, wear-resistant and durable, achieving the purpose of filtration during use.

[0035] Example 3

[0036] On the basis of the second embodiment, the novel spinneret assembly seat further comprises a first rubber sealing ring 110 sleeved on the outer wall of the circular plate 111;

[0037] The outer wall of the first rubber sealing ring 110 abuts against the lower inner walls of the two sets of arc-shaped limiting plates 109 . The above design forms a sealing protection for the circular plate 111 after assembly.

[0038] Example 4

[0039] On the basis of the second or third embodiment, the novel spinneret assembly seat further includes a second rubber sealing ring 118 sleeved on the outer wall of the spinneret 114;

[0040] Among them, the outer wall of the second rubber sealing ring 118 abuts against the upper inner wall of the two sets of arc-shaped limit plates 109, and the upper end face of the second rubber sealing ring 118 is flush with the upper end faces of the two sets of arc-shaped limit plates 109. After the above design is assembled, it forms a sealing protection for the spinneret 114 while ensuring the beauty of the end face.

[0041] In addition, the diameter of the circular filter hole 112 is preferably larger than the diameter of the conical plate opening 105, and the diameters of the conical plate opening 105, the circular transition plate opening 108, and the collecting trough 116 are the same. The above design ensures smooth raw material diversion and filtration.

[0042] In addition, the diameter of the circular filter hole 112 can also be designed to be smaller than the diameter of the tapered plate opening 105 to meet different design and use requirements.

[0043] The working principle or structural principle of the new spinneret assembly seat of this structure:

[0044] Please review Figure 1 、 Figure 2 , when assembling:

[0045] First, the first rubber sealing ring 110 and the second rubber sealing ring 118 are respectively mounted on the outer wall of the circular plate 111 and the outer wall of the spinneret 114;

[0046] Then, stack the conical plate 100, the circular transition plate 106, and the spinneret 114 in sequence, ensuring that the countersunk screw hole 101, the circular transition plate screw hole 107, the spinneret screw groove 115, the circular plate limiting screw hole 113, the conical plate material opening 105, the circular transition plate material opening 108, the circular filter hole 112, and the collecting trough 116 are vertically aligned one by one.

[0047] Finally, the conical plate 100 , the circular transition plate 106 and the spinneret 114 are fixed together by using the bolts 104 through the countersunk screw holes 101 , the circular transition plate screw holes 107 and the spinneret screw grooves 115 .
