Description

Technical Field

[0001] This utility model relates to the field of spinning equipment technology, specifically to a melt spinning spinneret for fiber synthesis. Background Technology

[0002] Spinning is the process of forming chemical fibers by making certain polymer compounds into colloidal solutions or melting them into melts and then extruding them through the fine holes of a spinneret. Therefore, during the spinning process, a spinneret is installed on the outside of the extrusion pipe, which drives the spinning and extrusion of fibers.

[0003] When using a spinneret to extrude fiber materials, the diameter of the extruded fibers needs to be adjusted. Therefore, when using melt spinning equipment, spinnerets with different orifice diameters are usually required to produce different filament diameters. During this process, the operator rotates the spinneret to replace it. However, when spinning the synthetic material, heating is required, which causes the spinneret to reach a high temperature. This can result in burns to the operator from the hot molten fiber material when replacing the spinneret, posing a safety hazard. To address this, we propose a melt spinning spinneret for fiber synthesis. Utility Model Content

[0004] To address the shortcomings of existing melt spinning spinnerets for fiber synthesis, this invention provides a melt spinning spinneret for fiber synthesis that features an adjustable plate that automatically adjusts the orifice size by rotating the plate, making orifice adjustment more convenient and solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a melt spinning spinneret for fiber synthesis, comprising a spinneret body, a limiting plate fixedly connected to the middle of the outer side of the spinneret body, a first extrusion hole opened inside the spinneret body, a conical plate installed inside the spinneret body, an inclined baffle fixedly connected to the outside of the conical plate, an adjusting plate installed at the front end of the spinneret body via a rotating disk, and a second extrusion hole, a third extrusion hole and a fourth extrusion hole opened at equal intervals inside the adjusting plate.

[0006] Preferably, the spinneret body is provided with a threaded groove on its exterior, and the spinneret body is threadedly installed at the front end of the melt spinning spinneret pipe.

[0007] Preferably, a positioning pin is installed inside the spinneret body, and the positioning pin passes through the spinneret body and is threaded inside the inclined baffle.

[0008] Preferably, eight sets of the first extrusion orifice and the inclined baffle are installed. The inclined baffle is located on one side of the first extrusion orifice, the outer side of the inclined baffle is inclined, and the inner side of the inclined baffle is attached to the inner side of the spinneret body.

[0009] Preferably, an adjustment disc is fixedly connected to the outside of the front end of the spinneret body, and the adjustment disc is movably sleeved on the outside of the lower end of the adjustment plate.

[0010] Preferably, the second, third, and fourth extrusion holes are aligned with the first extrusion hole, and the second and third extrusion holes are provided with wire holes inside, with one end of the wire hole being in contact with the end of the first extrusion hole.

[0011] Preferably, the second, third, and fourth extrusion holes have different diameters, and a sealing sleeve is fixedly connected to the outside of the adjustment plate.

[0012] Compared with existing melt spinning spinnerets for fiber synthesis, this invention has the following advantages:

[0013] 1. This melt spinning spinneret for fiber synthesis can adjust the direction of the adjusting plate by rotating the sealing sleeve. When the second, third, or fourth extrusion hole is connected to the first extrusion hole, the different extrusion spinning diameters can be adjusted, improving the flexibility of the spinneret in use.

[0014] 2. The melt spinning spinneret for fiber synthesis has a conical plate and an inclined baffle installed inside the spinneret body. At the same time, a positioning pin is installed inside the spinneret body. The positioning pin passes through the spinneret body and squeezes and limits the position of the inclined baffle, ensuring that the conical plate and the inclined baffle can be replaced inside the spinneret body. Meanwhile, the outside of the inclined baffle is inclined. After the molten material is diverted by the inclined baffle, it can be concentrated and squeezed into the interior of the first extrusion hole, ensuring sufficient extrusion of the molten material.

[0024] Please see Figure 1 The spinneret body 1 has a threaded groove installed on its exterior. The spinneret body 1 is threadedly installed at the front end of the melt spinning spinneret pipe. By opening the threaded groove on the exterior of the spinneret body 1 and installing it threadedly, the spinneret body 1 can be driven to be installed on the exterior of the melt spinning pipe. At the same time, the melting device melts the fiber, and the molten fiber is extruded through the spinneret body 1 to form fiber spinning, thereby completing the production of fiber spinning.

[0025] Please see Figure 2A positioning pin 6 is installed inside the spinneret body 1. The positioning pin 6 passes through the spinneret body 1 and is threaded inside the inclined baffle 5. The inclined baffle 5 is installed through the tapered plate 4 at the lower end of the spinneret body 1. The inclined baffle 5 is fitted inside the spinneret body 1. At the same time, the positioning pin 6 is installed inside the spinneret body 1. The positioning pin 6 passes through the spinneret body 1 and squeezes and limits the position of the inclined baffle 5 to ensure that the inclined baffle 5 remains stable when installed inside the spinneret body 1.

[0026] Please see Figure 2 The first extrusion hole 3 and the inclined baffle 5 are each equipped with eight sets. The inclined baffle 5 is located on one side of the first extrusion hole 3. The outside of the inclined baffle 5 is inclined. The inside of the inclined baffle 5 is attached to the inside of the spinneret body 1. The inclined baffle 5 is installed inside the spinneret body 1. At the same time, the inclined baffle 5 is located on the side of the first extrusion hole 3. When the molten fiber liquid is squeezed into the inside of the spinneret body 1, it is evenly squeezed inward through the first extrusion hole 3 by the diversion of the conical plate 4 and the inclined baffle 5.

[0027] Please see Figure 6 An adjustment disc 14 is fixedly connected to the front end of the spinneret body 1. The adjustment disc 14 is movably sleeved on the outside of the lower end of the adjustment plate 7. It is installed inside the spinneret body 1 through the sealing sleeve 9 and the rotating disc 8. At the same time, the adjustment disc 14 is installed on the outside of the spinneret body 1. The adjustment disc 14 is sleeved on the outside of the adjustment plate 7. The adjustment disc 14 seals the connection between the spinneret body 1 and the adjustment plate 7, thereby ensuring the sealing performance of the adjustment plate 7 while ensuring that the adjustment plate 7 can be rotated and adjusted at the front end of the spinneret body 1.

[0028] Please see Figure 5 The second extrusion hole 10, the third extrusion hole 11, and the fourth extrusion hole 12 are aligned with the first extrusion hole 3. The second extrusion hole 10 and the third extrusion hole 11 are provided with wire holes 13 inside. One end of the wire hole 13 is kept in contact with the end of the first extrusion hole 3. The second extrusion hole 10, the third extrusion hole 11, and the fourth extrusion hole 12 are provided inside the adjusting plate 7. By rotating the adjusting plate 7, the second extrusion hole 10, the third extrusion hole 11, and the fourth extrusion hole 12 are aligned with the first extrusion hole 3 in sequence. At the same time, the first extrusion hole 3 drives the fiber extrusion molding process. The second extrusion hole 10, the third extrusion hole 11, and the fourth extrusion hole 12 adjust the extrusion hole diameter. The wire holes 13 are provided inside the second extrusion hole 10 and the third extrusion hole 11. The wire holes 13 are aligned with the first extrusion hole 3 to ensure smooth fiber extrusion molding.

[0029] Please see Figure 4The diameters of the second extrusion hole 10, the third extrusion hole 11 and the fourth extrusion hole 12 are different. A sealing sleeve 9 is fixedly connected to the outside of the adjusting plate 7. By rotating the sealing sleeve 9, the adjusting plate 7 is driven to rotate. The adjusting plate 7 controls the angle and orientation of the second extrusion hole 10, the third extrusion hole 11 and the fourth extrusion hole 12 to be adjusted.

[0030] Working principle: In use, the conical plate 4 drives the inclined baffle 5 to be installed inside the spinneret body 1. At the same time, a positioning pin 6 is installed on the outside of the spinneret body 1. The positioning pin 6 drives the inclined baffle 5 to maintain stability when spliced ​​and limited inside the spinneret body 1. The spinneret body 1 is spirally installed on the outside of the extrusion pipe. After the fiber melts, it is extruded into the inside of the spinneret body 1. After being diverted by the conical plate 4 and the inclined baffle 5, the fiber melt material is ensured to maintain compactness after extrusion. At the same time, the fiber melt material is extruded into the inside of the second extrusion hole 10, the third extrusion hole 11 or the fourth extrusion hole 12 through the first extrusion hole 3, so that the diameter of the extruded material can be adjusted.
