Description

Technical Field

[0001] This utility model relates to the field of material spinning technology, specifically a heatable spinneret. Background Technology

[0002] A spinneret, also known as a spinning cap, is an important device that transforms viscous polymer melts or solutions into fine streams with specific cross-sectional shapes through micropores, and then solidifies them through a coagulation medium to form filaments. In order to make the material temperature more uniform during the spinning process, heated spinnerets are commonly used for spinning operations.

[0003] When using existing spinnerets, a viscous polymer melt or solution is poured into the feed inlet of the spinneret. The molten material is forced through the spinneret holes by its own pressure or external pressure, and then cooled and shaped in a cooling medium (such as air).

[0004] In existing spinnerets, the temperature of the molten solute is lost during use. Although some spinnerets with heating functions can heat the solute, the flow of hot air also causes temperature loss. This results in uneven temperature of the molten material during the spinning process, leading to defects on the fiber surface, such as unevenness or inconsistent thickness, which affects the smoothness and uniformity of the fiber. To address this, we propose a heated spinneret. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a heatable spinneret with spiral pipes around the spinneret holes to guide high-temperature air. The high-temperature hot air surrounds the spinneret holes and continuously heats the molten material during the spinnereting process, thereby ensuring the temperature uniformity of the molten material during the spinnereting process and thus ensuring the spinnereting quality. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heatable spinneret, comprising a plate body;

[0007] Plate body: A material storage tank is opened on the upper side of the plate body, and evenly distributed spinneret holes are opened on the lower side of the plate body. A heat exchanger is fixedly connected to the right surface of the plate body. A heating tank is opened on the right side of the plate body. Evenly distributed electric heating wires are fixedly connected inside the heating tank. Evenly distributed spiral pipes are opened on the lower side of the plate body. The upper ends of the spiral pipes are all connected to the heating tank. The spinneret holes are all located inside the vertically adjacent spiral pipes. The vertically adjacent spinneret holes coincide with the central axis of the spiral pipes. Spiral pipes are opened around the spinneret holes to guide high-temperature air. The high-temperature hot air surrounds the spinneret holes and continuously heats the molten material during the spinnereting process, thereby ensuring the temperature uniformity of the molten material during the spinnereting process and thus ensuring the spinnereting quality.

[0008] Furthermore, a control switch group is provided on the outside of the plate. The input end of the control switch group is electrically connected to an external power source, and the input end of the electric heating wire is electrically connected to the output end of the control switch group to control the operation of the electrical appliances.

[0009] Furthermore, each of the spinnerets consists of a conical guide hole I, a conical guide hole II, and a straight hole that are connected from top to bottom. The diameter of the conical guide hole I is larger than the diameter of the conical guide hole II, guiding the material through the spinneret to form the material.

[0010] Furthermore, the lower end of each spiral pipe is fixedly connected to an air pipe four, the upper end of each air pipe four is connected to the hot air inlet of the heat exchanger, and the rear side of the hot air outlet of the heat exchanger is fixedly connected to an air pipe two to discharge hot air and recover heat from the hot air.

[0011] Furthermore, a third air pipe is fixedly connected to the rear side of the cold air inlet of the heat exchanger, and a first air pipe is fixedly connected to the front side of the cold air outlet of the heat exchanger. The front end of the first air pipe is connected to the heating tank to guide external air in.

[0012] Furthermore, a diversion fan is fixedly connected to the rear side of the inner side of the air pipe three. The input end of the diversion fan is electrically connected to the output end of the control switch group, so that external air enters the heating tank through the heat exchanger.

[0013] Furthermore, the upper surface of the plate has evenly distributed mounting holes on both the left and right sides to facilitate the fixed installation of the plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This heatable spinneret has the following advantages:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This embodiment provides a technical solution: a heatable spinneret, including a plate body 1;

[0023] Plate 1: A storage tank 2 is provided on the upper side of its interior. Evenly distributed spinneret holes 12 are provided on the lower side of the interior of plate 1. Each spinneret hole 12 consists of a conical guide hole 121, a conical guide hole 122, and a straight hole 123 connected from top to bottom. The diameter of the conical guide hole 121 is larger than the diameter of the conical guide hole 122. Evenly distributed mounting holes 3 are provided on both the left and right sides of the upper surface of plate 1. A heat exchanger 5 is fixedly connected to the right surface of plate 1. A heating groove 10 is provided on the right side of the interior of plate 1. Evenly distributed electric heating wires 11 are fixedly connected inside the heating groove 10. A control switch group 14 is provided on the outside of plate 1. The input terminal of the switch group 14 is electrically connected to an external power source. The input terminals of the electric heating wire 11 are all electrically connected to the output terminals of the control switch group 14. Uniformly distributed spiral pipes 13 are provided on the lower inner side of the plate body 1. The upper ends of the spiral pipes 13 are all connected to the heating tank 10. The spinnerets 12 are all located inside the vertically adjacent spiral pipes 13, and the vertically adjacent spinnerets 12 coincide with the central axis of the spiral pipes 13. Air pipes 9 are fixedly connected to the lower ends of the spiral pipes 13. The upper ends of the air pipes 9 are all connected to the hot air inlet of the heat exchanger 5. Air pipes 6 are fixedly connected to the rear side of the hot air outlet of the heat exchanger 5. Air pipes 6 are also fixedly connected to the rear side of the cold air inlet of the heat exchanger 5. A third air pipe 7 is fixedly connected to the side of the heat exchanger 5. A first air pipe 4 is fixedly connected to the front side of the cold air outlet of the heat exchanger 5. The front end of the first air pipe 4 is connected to the heating tank 10. A diversion fan 8 is fixedly connected to the rear side of the inside of the third air pipe 7. The input end of the diversion fan 8 is electrically connected to the output end of the control switch group 14. When the control switch group 14 is operated, the electric heating wire 11 and the diversion fan 8 are started. The diversion fan 8 runs and introduces outside air into the interior of the heat exchanger 5 through the third air pipe 7, and into the interior of the heating tank 10 through the first air pipe 4. The heated gas enters the interior of the heat exchanger 5 through the spiral pipe 13 and the fourth air pipe 9. Under the action of the heat exchanger 5, the exhaust gas is discharged. The heat inside the hot air is recovered and transferred to the air entering the heat exchanger 5. The hot air that has recovered its energy is discharged through the air pipe 6. The molten material is placed in the storage tank 2. Under its own pressure or external pressure (by extruding the molten material through an external pressurizing device), the molten material enters the spinneret 12. Guided by the spinneret 12, the molten material is shaped and flows out through the lower end of the spinneret 12. At the same time, the hot air passes through the spiral pipe 13 outside the spinneret 12 to continuously heat the molten material inside the spinneret 12. Under the action of the cooling medium (such as air), the material is cooled and shaped.

[0024] The working principle of the heated spinneret provided by this utility model is as follows: When using the heated spinneret for spinning operations, the control switch group 14 is operated to start the electric heating wire 11 and the guiding fan 8. The guiding fan 8 runs, introducing external air into the interior of the heat exchanger 5 through air pipe three 7, and then into the interior of the heating tank 10 through air pipe one 4. The electric heating wire 11 runs, heating the gas inside the heating tank 10. The heated gas enters the interior of the heat exchanger 5 through the spiral pipe 13 and air pipe four 9. Under the action of the heat exchanger 5, the heat inside the discharged hot air is recovered. The heat is transferred to the air entering the heat exchanger 5. The hot air, after energy recovery, is discharged through the air pipe 6. The molten material is placed in the storage tank 2. Under its own pressure or external pressure (by extruding the molten material through an external pressurizing device), the molten material enters the spinneret 12. Guided by the spinneret 12, the molten material is shaped and flows out through the lower end of the spinneret 12. At the same time, the hot air passes through the spiral pipe 13 outside the spinneret 12 to continuously heat the molten material inside the spinneret 12. Under the action of the cooling medium (such as air), the material is cooled and shaped.
