Description

Technical Field

[0001] The utility model relates to the field of spinning devices, in particular to a spinning device with adjustable spinning thickness. Background Art

[0002] The spinneret uses a spinneret to eject liquid or solution polymers through a fine-hole spinneret to form a continuous fiber stream. These fiber streams are gradually solidified into fiber bundles through the traction and stretching of air, and finally form spinning lines. The spinneret is a device used for spinning, usually made of iron, copper, stainless steel or other metals, with many tiny holes on the surface of the plate. The design of the spinneret and the control of operating parameters have an important influence on the diameter and distribution of the spun fibers.

[0003] Different fields have specific requirements for the diameter specifications of the wire, so different spinneret diameters are needed. The thickness of the wire will also affect the stability of the spinning process. Too thick may lead to extrusion difficulties, excessive tensile stress or uneven deposition. Too thin may be difficult to pull due to insufficient tension or be affected by the external environment and break. Therefore, the spinneret diameter needs to be adjusted according to different materials. However, each spinneret plate is usually only provided with one spinneret diameter. If the spinneret diameter is to be adjusted, the spinneret plate must be replaced, which is troublesome to replace and takes a long time to adjust, affecting production efficiency. Therefore, a spinneret device with adjustable spinneret thickness is proposed to solve the above problems. Summary of the invention

An extrusion hole 5 for extruding a polymer material to form a spinning line is provided inside the spinneret 4, and the extrusion hole 5 is provided with four different diameters, and the extrusion holes 5 of each diameter are distributed in a fan shape with an arc angle of 22.5°.

[0030] Reference Figure 3A limiting column groove 8 is provided on the top of the fixing ring 6. Sixteen groups of limiting column grooves 8 are arranged, which are evenly distributed in an annular shape on the top of the fixing ring 6. An elastic component is fixedly connected inside the bottom end of the limiting column groove 8. The elastic component includes a limiting spring 9. The bottom end of the limiting spring 9 is fixedly connected to the inner wall of the bottom end of the limiting column groove 8. The top end of the limiting spring 9 is fixedly connected to the bottom end of the limiting ball 10. When the limiting ball 10 is not subjected to force, the limiting spring 9 will push the limiting ball 10 upward, and the limiting ball 10 The outer periphery is slidably connected to the inside of the limiting column groove 8. The bottom diameter of the limiting column groove 8 is the same as that of the limiting ball 10, but the top is slightly retracted inward, so that the limiting ball 10 can protrude from the top of the limiting column groove 8 but cannot fall out. A spherical card slot 11 is provided at the bottom of the connecting ring 1. There are sixteen groups of spherical card slots 11, which are evenly distributed in an annular shape at the bottom of the connecting ring 1, and the position of the spherical card slot 11 is opposite to the limiting column groove 8. The top of the limiting ball 10 is clamped in the inside of the spherical card slot 11.

[0031] Reference Figure 1-Figure 3 , a fixed circular block 12 for fixed connection is fixedly connected to the top of the baffle plate 2, a fixed threaded sleeve 13 is fixedly connected to the top of the fixed circular block 12, and threads are arranged inside and outside the fixed threaded sleeve 13, a rotating threaded column 14 is slidably connected to the inside of the spinneret 4, and the spinneret 4 can rotate freely at the outer periphery of the rotating threaded column 14, the outer periphery of the rotating threaded column 14 is slidably connected to the inside of the baffle plate 2, the outer periphery of the rotating threaded column 14 is slidably connected to the inside of the fixed circular block 12, a thread groove 15 is provided on the upper part of the side wall of the rotating threaded column 14, the internal thread of the fixed threaded sleeve 13 is connected to the outer periphery of the thread groove 15, and the rotating threaded column 14 is fixedly connected to the bottom of the rotating threaded column 14 with a supporting block 16, and the top of the supporting block 16 is rotatably connected to a rotating circular block 17, the outer periphery of the rotating threaded column 14 is rotatably connected to the inside of the rotating circular block 17, and the top of the rotating circular block 17 contacts with the bottom of the spinneret 4, so that after the rotating threaded column 14 is tightened, the spinneret 4 can still rotate.

[0032] Working principle: when you want to conveniently adjust the spinneret diameter of the spinneret 4, turn the rotating ring 7. The rotating ring 7 rotates, driving the fixed ring 6 to rotate, and the fixed ring 6 drives the spinneret 4 to rotate. At the same time, the fixed ring 6 drives the limiting ball 10 to rotate. The limiting ball 10 is squeezed by the spherical groove 11, and the horizontal force is partially converted into a downward force through the arc surface. At this time, the limiting ball 10 will move downward along the limiting column groove 8 and squeeze the limiting spring 9. After rotating 22.5°, the limiting ball 10 encounters the next adjacent spherical groove 11. At this time, the limiting ball 10 moves upward under the push of the limiting spring 9 and is stuck in the spherical groove 11. At this time, the spinneret 4 has rotated 22.5°, thereby changing the extrusion hole 5 passing through the groove 3, thereby conveniently adjusting the spinneret diameter of the spinneret 4. When it is desired to prevent the polymer material extruded downward during the spinning process from causing the spinneret 4 to fall off, the fixed threaded sleeve 13 is first rotated to fix the fixed threaded sleeve 13 on the spinneret, and then the rotating threaded column 14 is inserted into the fixed threaded sleeve 13 and the rotating threaded column 14 is rotated to connect the two tightly. At this time, the rotating round block 17 can still rotate the spinneret 4, and the supporting block 16 provides a supporting force, so that the spinneret 4 can work continuously for a long time.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
