The change device includes a first rectangular hole opened on one side of the plate body. A second rectangular hole is opened on one side of the plate body. The second rectangular hole communicates with the first rectangular hole. A microporous plate is slidably inserted into the second rectangular hole. By setting the change device, the blocked microporous plate can be removed from the inside of the first rectangular hole and the second rectangular hole and quickly separated from the plate body. At the same time, another microporous plate is inserted into the first rectangular hole and the second rectangular hole for alternative use, reducing the situation that the direct disassembly of the plate body causes the machine body to stop running for a long time and affects the production of polyamide filaments, and improving the convenience of replacing the blocked microporous plate.

[0004] The above-mentioned spinneret for producing antistatic polyamide fibers has some problems in use. Although the above-mentioned can reduce the situation that the direct disassembly of the plate body causes the machine body to stop running for a long time and affects the production of polyamide filaments, it can only produce fibers of a single model and cannot produce multiple fibers, so the practicability is relatively low. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rectangular spinneret to solve the problem of low practicability that only fibers of a single model can be produced and multiple fibers cannot be produced as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , this embodiment provides a rectangular spinneret plate, including a mounting frame 100. Two groups of plate bodies 102 are arranged in the inner cavity of the mounting frame 100. Extrusion holes 105 are formed on the surfaces of the two groups of plate bodies 102. The plate body 102 located above is fixedly installed in the inner cavity of the mounting frame 100, and the plate body 102 located below is slidably connected to the inner cavity of the mounting frame 100. A moving component for moving the plate body 102 located below is arranged inside one side of the mounting frame 100, and several groups of connection holes 101 are formed on the surface of the mounting frame 100;

[0026] The moving component includes a sliding groove 201 opened on the inner wall surface of one side of the mounting frame 100. A lead screw 203 is rotatably connected to the inner cavity of the sliding groove 201. A nut seat 103 is threadedly connected to the surface of the lead screw 203. The nut seat 103 is fixedly connected to the surface of the lower plate body 102. One end of the lead screw 203 is provided with a rotating member for rotating the lead screw 203. Through the setting of the moving component, the lead screw 203 rotates, and then drives the lower plate body to be pushed to one side through the nut seat 103, so that the relative position between the upper and lower two groups of plate bodies 102 can be adjusted. Furthermore, the overlapping area of the two extrusion holes 105 at the same position can be flexibly controlled, so that fibers of various shapes can be manufactured, and the practicability is further improved.

[0027] Further, the rotating member includes a connecting rod 204 fixedly connected to one end of the lead screw 203. One end of the connecting rod 204 penetrates through the mounting frame 100 and extends to the outside of the mounting frame 100. One end of the connecting rod 204 located outside the mounting frame 100 is fixedly connected with a hand wheel 200. Through the setting of the rotating member, the connecting rod 204 connects the hand wheel 200 and the lead screw 203, which is convenient for the operator to control the rotation of the lead screw 203 by rotating the hand wheel 200 outside the mounting frame 100, and the operation is simple and convenient.

[0028] Furthermore, bearings 202 are fixedly sleeved on both ends of the lead screw 203. The two groups of bearings 202 are respectively embedded in the corresponding inner wall surfaces of the sliding groove 201. Through the setting of the bearings 202, the bearings 202 reduce the friction force when the lead screw 203 rotates, making the operation easier and more labor-saving. The bearings 202 embedded in the inner wall of the sliding groove 201 ensure the installation stability of the lead screw 203, prevent the lead screw 203 from shaking or shifting during the rotation process, and improve the precision and reliability of the device.

[0029] Preferably, a limiting hole 302 is opened on one side surface of the mounting frame 100 at a position corresponding to the nut seat 103. A threaded rod 300 is fixedly connected to the surface of the nut seat 103. One end of the threaded rod 300 penetrates through the limiting hole 302 and extends to the outside of the mounting frame 100. One end of the threaded rod 300 is threadedly connected with a hand-tightening nut 301. One end of the hand-tightening nut 301 is closely attached to the surface of the mounting frame 100. Through the setting of the limiting hole 302 and the threaded rod 300, the limiting hole 302 provides a passage for the threaded rod 300 to pass through, so that the threaded rod 300 can move within a certain range as the lower plate body 102 moves. The cooperation of the threaded rod 300 and the hand-tightening nut 301 can be tightened after the position of the lower plate body 102 is adjusted, preventing the plate body 102 from accidentally moving during the working process, and improving the stability and safety of the device.

[0030] It should be noted that one end of the lower plate body 102 facing the nut seat 103 is fixedly connected with a limiting plate 104. A limiting groove 106 corresponding to the limiting plate 104 is opened on one inner wall of the mounting frame 100 at a position corresponding to the limiting plate 104. The limiting plate 104 is slidably connected to the inner cavity of the limiting groove 106. Through the arrangement of the limiting groove 106 and the limiting block, the limiting plate 104 slides in the limiting groove 106, ensuring that the lower plate body 102 can only move along a specific direction, avoiding deviation or skew, and ensuring the alignment accuracy of the extrusion holes 105.

[0031] Furthermore, a blocking piece 107 is provided at the bottom of the upper plate body 102 and on one side of each group of extrusion holes 105. One side of the blocking piece 107 extends into the inner cavity of the extrusion hole 105 at the corresponding position below. Through the arrangement of the blocking piece 107, the blocking piece 107 can prevent the backflow or cross-contamination of the extrudate. The blocking piece 107 is on one side of the extrusion hole 105 and extends into the inner cavity of the lower extrusion hole, effectively blocking the reverse flow of the extrudate, ensuring the unidirectionality of the extrusion process, reducing the mutual interference between different extrusion holes 105, and improving the accuracy and quality of the extrusion operation.

[0032] Working principle;

[0033] The rectangular spinneret plate is fixedly connected to the machine through the connection holes 101. Then, the machine is started. The material produced by the machine first flows downward through the upper extrusion holes 105, and after being limited by the blocking piece 107, it flows into the lower extrusion holes 105 and flows out from them, thus completing the shaping of the material. When the material needs to be shaped into other shapes, first rotate the handwheel 200. The handwheel 200 drives the lead screw 203 to rotate, so as to drive the lower plate body to be pushed to one side through the nut seat 103. The extrusion holes 105 opened on the upper and lower groups of plate bodies 102 coincide, so that the upper and lower extrusion holes 105 are arranged in an oval shape. At the same time, the handwheel 200 can be rotated in the reverse direction to push the lower plate body 102 to the other side, so that the upper and lower groups of extrusion holes 105 are in a rounded square shape. And the handwheel 200 can be continuously rotated. Further, the lower plate body 102 is pushed to the other side to extend the length of the rounded square. When adjusted to the required shape, tighten the hand-tightening nut 301 to fix the lower plate body 102.

[0034] It should be noted that the aperture of the lower extrusion hole 105 is smaller than the aperture of the upper extrusion hole 105, so that the lower extrusion hole 105 forms a spinneret hole.

[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
