Description

Technical Field

[0001] This utility model relates to the field of nylon filament production technology, specifically to a nylon filament spinneret. Background Technology

[0002] In the production of nylon filament, a spinneret, also known as a spinning cap, is required. Its function is to transform a viscous polymer melt or solution into a fine stream with a specific cross-sectional shape through micropores, which then solidifies into filaments through a solidification medium such as air or a solidification bath. A Chinese patent with authorization publication number CN211897194U discloses a spinneret for coarse denier nylon filament, comprising a spinneret and spinneret holes arranged concentrically on at least two concentric circles. The spinneret has annular cooling air channels arranged along each concentric circle and a linear cooling air channel radially arranged along the airflow direction. The linear cooling air channel has an air inlet and an air outlet at both ends, and the annular cooling air channel and the linear cooling air channel are interconnected. This invention is used in the production of nylon coarse denier yarn, enabling the denier yarn in the inner spinneret holes to dissipate heat quickly and fully, thereby improving the spinning quality; and the ribs formed between the cooling air channels and each ring of spinnerets can improve the rigidity of the spinneret, enhance its pressure resistance, and increase its service life.

[0003] However, in practical applications, the above-mentioned spinnerets still have the following shortcomings: Although the spinnerets can improve the rigidity of the spinnerets, as the diameter specifications of nylon yarns increase, if different specifications of nylon yarns are to be spun, it is necessary to stop the machine and replace different spinnerets. This not only results in long replacement time and reduced nylon yarn production efficiency, but also increases production costs due to the need to keep multiple spinnerets on hand, making them less practical. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a nylon filament spinneret that eliminates the need for prolonged downtime when changing the diameter of the nylon filament, thus ensuring the production efficiency of the nylon filament. Furthermore, it eliminates the need for multiple spare spinnerets, reducing production costs and improving practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A nylon filament spinneret includes a cylindrical plate hoop, a base plate and a mounting plate installed within the plate hoop, an adjusting plate rotatably connected within the plate hoop, and an adjusting mechanism for driving the adjusting plate to rotate. The adjusting plate is disposed between the base plate and the mounting plate, and the adjusting mechanism is mounted on the plate hoop. The base plate is provided with four sets of liquid inlet holes, which are equidistant from the axis of the plate hoop. The adjusting plate is provided with four sets of spinneret hole group one, four sets of spinneret hole group two, four sets of spinneret hole group three, and four sets of spinneret hole group four, which are equidistant from the axis of the plate hoop.

[0007] Each set of liquid inlet holes includes five liquid inlet holes that are equidistantly distributed outward from the axis of the plate hoop, and the mounting plate is provided with through holes directly opposite the liquid inlet holes;

[0008] Any group of spinneret holes includes five spinneret holes radiating outwards at equal intervals from the axis of the plate clamp; any group of spinneret holes includes five spinneret holes radiating outwards at equal intervals from the axis of the plate clamp; any group of spinneret holes includes five spinneret holes radiating outwards at equal intervals from the axis of the plate clamp; any group of spinneret holes includes five spinneret holes radiating outwards at equal intervals from the axis of the plate clamp; any group of spinneret holes includes five spinneret holes radiating outwards at equal intervals from the axis of the plate clamp. The diameters of the spinneret holes 1, 2, 3, and 4 are different. During the rotation of the adjusting plate driven by the adjusting mechanism, the spinneret holes 1, 2, 3, or 4 are aligned with the liquid inlet and the through hole.

[0009] Furthermore, the diameters of the first, second, third, and fourth spinnerets gradually increase.

[0010] Furthermore, an opening is provided on one side of the plate hoop; the adjustment mechanism includes a rotating shaft rotatably connected to one side of the plate hoop, a drive gear and a knob disposed on the rotating shaft, and an external gear disposed on the adjustment plate, wherein the drive gear extends into the opening and meshes with the external gear.

[0011] Furthermore, the opening is arc-shaped and is centered on the axis of the rotating shaft. The plate hoop is provided with scale one, scale two, scale three and scale four, which are centered on the axis of the rotating shaft. The knob is provided with an arrow.

[0012] Furthermore, the base plate and the mounting plate are slidably connected within the plate clamp. The adjusting plate is symmetrically provided with arc-shaped locking grooves, which are symmetrically arranged with the axis of the plate clamp as the center. A stud is rotatably connected within the arc-shaped locking groove. The stud is rotatably connected to the plate clamp. Two external threads, one and two, with opposite directions of rotation are provided adjacently on the stud. The base plate and the mounting plate are respectively provided with internal thread holes one and two, facing the external threads one and two. The bottom end of the stud passes through the arc-shaped locking groove and is tightened by tightening the nut.

[0013] Furthermore, the diameter of the liquid inlet gradually decreases from top to bottom.

[0014] The beneficial effects of this utility model are:

[0015] In practical applications, during use, the viscous polymer melt or solution enters the inlet hole, and after passing through spinneret one, two, three, or four, it is transformed into fine filaments and ejected from the through hole. When it is necessary to change the diameter of the nylon filament, the adjustment mechanism drives the adjustment plate to rotate, adjusting the spinneret directly opposite the inlet hole and the through hole, thereby changing the diameter of the ejected nylon filament. This invention eliminates the need for long-term machine downtime to replace the spinneret when the diameter of the nylon filament needs to be changed, ensuring the production efficiency of nylon filament, and also eliminates the need for multiple spare spinnerets, reducing production costs and improving practicality.

[0021] like Figure 1-5As shown, a nylon spinneret includes a cylindrical plate hoop 1, a base plate 2 and a mounting plate 3 installed inside the plate hoop 1, an adjusting plate 4 rotatably connected inside the plate hoop 1, and an adjusting mechanism for driving the adjusting plate 4 to rotate. The adjusting plate 4 is disposed between the base plate 2 and the mounting plate 3. The adjusting mechanism is mounted on the plate hoop 1. The base plate 2 is provided with four sets of liquid inlet holes, which are arranged at equal angles around the axis of the plate hoop 1. The adjusting plate 4 is provided with four sets of spinneret hole group one, four sets of spinneret hole group two, four sets of spinneret hole group three and four sets of spinneret hole group four, which are arranged at equal angles around the axis of the plate hoop 1.

[0022] Each set of liquid inlet holes includes five liquid inlet holes 21 that are equidistantly distributed outward from the axis of the plate hoop 1, and the mounting plate 3 is provided with through holes 31 facing the liquid inlet holes 21;

[0023] Any group of the spinneret holes includes five spinneret holes 41 equidistantly distributed outward from the axis of the plate hoop 1; any group of the spinneret holes includes five spinneret holes 42 equidistantly distributed outward from the axis of the plate hoop 1; any group of the spinneret holes includes five spinneret holes 43 equidistantly distributed outward from the axis of the plate hoop 1; any group of the spinneret holes includes five spinneret holes 44 equidistantly distributed outward from the axis of the plate hoop 1. The diameters of the spinneret holes 41, 42, 43, and 44 are different. During the rotation of the adjusting plate 4 driven by the adjusting mechanism, the spinneret holes 41, 42, 43, or 44 are aligned with the liquid inlet hole 21 and the through hole 31.

[0024] In use, the viscous polymer melt or solution enters the inlet hole 21, and after passing through the spinneret hole 41, spinneret hole 42, spinneret hole 43, or spinneret hole 44, it is transformed into fine filaments and ejected from the through hole 31. When it is necessary to change the diameter of the nylon filament, the adjusting mechanism drives the adjusting plate 4 to rotate, adjusting the spinneret hole facing the inlet hole 21 and the through hole 31, thereby changing the diameter of the ejected nylon filament. This utility model eliminates the need for long-term machine downtime to replace the spinneret when the diameter of the nylon filament needs to be changed, ensuring the production efficiency of nylon filament, and also eliminates the need for multiple spare spinnerets, reducing production costs and improving practicality.

[0025] like Figure 1-5 As shown, the diameters of the spinneret 1 41, spinneret 2 42, spinneret 3 43 and spinneret 44 gradually increase; in this embodiment, when the diameters of the spinneret 1 41, spinneret 2 42, spinneret 3 43 and spinneret 44 gradually increase, the adjustment of the nylon filament diameter is more convenient.

[0026] like Figure 1-5 As shown, an opening 11 is provided on one side of the plate hoop 1; the adjustment mechanism includes a rotating shaft 51 rotatably connected to one side of the plate hoop 1, a drive gear 52 and a knob 53 provided on the rotating shaft 51, and an external gear 45 provided on the adjustment plate 4. The drive gear 52 extends into the opening 11 and meshes with the external gear 45. In this embodiment, when the knob 53 is turned, the knob 53 drives the external gear 45 and the adjustment plate 4 to rotate through the drive gear 52 on the rotating shaft 51, thereby adjusting the spinneret hole facing the liquid inlet hole 21 and the through hole 31.

[0027] like Figure 1-5 As shown, the opening 11 is arc-shaped and centered on the axis of the rotating shaft 51. The plate hoop 1 is provided with scales 12, 13, 14, and 15, all centered on the axis of the rotating shaft 51. The knob 53 is provided with an arrow 531. In this embodiment, when the arrow 531 of the knob 53 is aligned with scale 12, the spinneret 41 is aligned with the inlet hole 21 and the through hole 31, and the viscous polymer melt or solution is ejected through the inlet hole 21, spinneret 41, and through hole 31 to obtain nylon yarn of the first diameter specification. After the knob 53 rotates one revolution, when the arrow 531 is aligned with scale 23, the spinneret 42 is aligned with the inlet hole 21 and the through hole 31, and the viscous polymer melt or solution is ejected through the inlet hole 21, spinneret 41, and through hole 31 to obtain nylon yarn of the first diameter specification. The nylon filament is ejected through the inlet hole 21, the spinneret hole 42, and the through hole 31 to obtain the second diameter specification. After rotating knob 53 one full turn, when arrow 531 is aligned with scale 14, the spinneret hole 43 is aligned with the inlet hole 21 and the through hole 31, and the viscous polymer melt or solution is ejected through the inlet hole 21, the spinneret hole 43, and the through hole 31 to obtain the third diameter specification. After rotating knob 53 one full turn, when arrow 531 is aligned with scale 15, the spinneret hole 44 is aligned with the inlet hole 21 and the through hole 31, and the viscous polymer melt or solution is ejected through the inlet hole 21, the spinneret hole 44, and the through hole 31 to obtain the fourth diameter specification. This process eliminates the need for long-term machine downtime to replace the spinneret, ensuring the production efficiency of the nylon filament. It also eliminates the need for multiple spare spinnerets, reducing production costs and improving practicality.

[0028] like Figure 1-5As shown, the base plate 2 and mounting plate 3 are slidably connected within the plate clamp 1. The adjusting plate 4 has symmetrically arranged arc-shaped locking grooves 46, symmetrically arranged around the axis of the plate clamp 1. A stud 6 is rotatably connected within the arc-shaped locking groove 46, and the stud 6 is rotatably connected to the plate clamp 1. The stud 6 has two adjacent external threads, one 61 and the other 62, with opposite directions of rotation. The base plate 2 and mounting plate 3 have internal thread holes one and two, respectively, opposite to the external threads 61 and 62. The bottom end of the stud 6 passes through the arc-shaped locking groove 46 and is tightened by screws. Tighten cap 63; In this embodiment, when it is necessary to adjust the diameter of the nylon filament, loosen the tightening nut 63, and rotate the stud 6 clockwise. Since the stud 6 is screwed to the base plate 2 through the external thread 61 and the internal thread hole 1, and screwed to the mounting plate 3 through the external thread 62 and the internal thread hole 2, the base plate 2, the mounting plate 3 and the adjusting plate 4 are separated. The adjusting mechanism drives the adjusting plate 4 to rotate, and adjusts the spinneret hole facing the liquid inlet hole 21 and the through hole 31, thereby changing the diameter of the nylon filament that is ejected. After the diameter of the nylon filament is adjusted, rotate the stud 6 counterclockwise, so that the base plate 2 and the mounting plate 3 are close to each other and pressed against the adjusting plate 4. Tighten the tightening nut 63 to fix the stud 6 to the plate clamp 1.

[0029] like Figure 1-5 As shown, the diameter of the inlet hole 21 gradually decreases from top to bottom; in this embodiment, when the diameter of the inlet hole 21 gradually decreases from top to bottom, the viscous polymer melt or solution is more likely to enter the inlet hole 21.

[0030] The specific embodiments described herein are merely illustrative examples of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by this utility model.
