Description

Technical Field

[0001] The embodiments of the present application relate to the field of spinning technology, and in particular to a spinning assembly, a spinning box, and a melt spinning machine. Background Art

[0002] In the existing textile industry, a melt spinning machine is a unit that forms a filament (thread) from a fiber-forming polymer melt. In the production process of the melt spinning machine, annular air (or side air) is used to cool the unformed filaments. However, in order to avoid sudden cooling that affects the elongation and strength of the final formed thread, the unformed filaments (i.e., before being discharged from the spinneret) and the threads (i.e., the threads just discharged from the spinneret) in the capillary pores of the spinneret need to be kept warm to achieve the purpose of a gradual cooling process (slow cooling), thereby improving the elongation and strength of the final thread.

[0003] Currently, heating is usually performed by connecting an additional heat source to a heating plate integrated in the spinning manifold, thereby achieving the purpose of keeping the spinneret and the filaments just discharged from the spinneret warm.

Summary of the invention

[0030] The implementation of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0031] Embodiments of the first aspect

[0032] An embodiment of the first aspect of the present application provides a spinning assembly.

[0033] Figure 1 is a schematic diagram of a spinning manifold according to an embodiment of the first aspect of the present application, which shows a cross-sectional view of several spinning assemblies included in the spinning manifold; Figure 2 yes Figure 1 One of the spinning components ( Figure 1 The enlarged view of the dashed box F1); Figure 3 It is an exploded view of the heat conduction component of the embodiment of the first aspect of the present application.

[0034] like Figure 1 and Figure 2 As shown, the spinning assembly 20 installed in the assembly hole 10 of the spinning beam 1 may include a shell 201 and a spinneret 202 . The spinneret 202 is located at the lower end of the spinning assembly 20 and contacts the bottom 2011 of the shell 201 in the radial direction.

[0035] like Figure 2 As shown, the spinning assembly 20 may further include a heat conduction component 203, wherein the heat conduction component 203 is in contact with the bottom 2011 of the shell 201 and the inner wall 101 of the assembly hole 10 respectively, and the heat conduction component 203 conducts the heat of the inner wall 101 of the assembly hole 10 to the spinneret 202 via the bottom 2011 of the shell 201 by heat conduction, so as to heat the spinneret 202.

[0036] That is to say, the spinning manifold itself is used as a heat source (as is well known, the outer shell of the spinning manifold 1 itself is a heat source, and therefore, the assembly hole 10 formed by the outer shell of the spinning manifold 1 is the heat source), and the heat is conducted from the inner wall 101 of the assembly hole 10 to the spinneret 202 via the heat conduction component 203 and the bottom 2011 of the shell 201 of the spinning assembly 20, thereby increasing the capillary temperature in the spinneret 202, keeping the unformed filaments in the capillaries (i.e., the melt before being discharged from the spinneret) warm, and improving the flow state of the melt in the spinneret 202.

[0037] According to the above embodiment, the heat of the spinning box 1 is used to heat the spinneret 202 of the spinning assembly 20 by using the heat conduction component 203 which is in contact with the shell 201 of the spinning assembly 20 and the component hole 10 of the spinning box 1 respectively, that is, a passive heating method is adopted, which does not require an additional heat source and is beneficial to energy saving; the spinneret 202 is heated by heat conduction, which has a higher heating efficiency than the heating method by thermal radiation, and improves the quality index of the final silk thread (including elongation and strength, etc.); there is no need to integrate the heat conduction component 203 in the spinning box 1, which is convenient for disassembly and has a simple structure.

[0038] In the embodiments of the present application, Figure 2 and Figure 3 The heat conduction component 203 is shown as an example of a heating ring, but the present application is not limited thereto, and any structure of a heat conduction component that heats the spinneret in a heat conduction manner is included in the present application.

[0039] In the embodiments of the present application, Figure 2 and Figure 3 As shown, the heat conducting component 203 is formed into an annular heat transfer ring 203a, and the heat transfer ring 203a includes a heat transfer ring 203a extending in the up and down directions (in Figure 2 The heat transfer ring 203a has an outer wall portion 2031a extending therefrom as shown by arrow A, an upper surface S1 of the wall portion 2031a contacts the bottom 2011 of the shell 201 of the spinning assembly 20 in the up and down directions, and a diameter D1 of the heat transfer ring 203a can be adjusted so that an outer surface S2 of the wall portion 2031a contacts the inner wall 101 of the assembly hole 10 in the radial direction.

[0040] Thus, the heat conduction component 203 can be realized through a simple annular structure; and the wire just discharged from the spinneret 202 can be insulated by heat radiation in the radial direction through the wall portion 2031a. Compared with the traditional heat radiation through the component hole to insulate the wire just discharged from the spinneret 202, due to the radial thickness of the wall portion 2031a, it is equivalent to reducing the inner diameter of the heat source, that is, the heating source of the wire is closer to the wire, so that the heat radiation capacity is stronger, which avoids the sudden cooling of the wire, and can further improve the elongation and strength of the final wire.

[0041] On the other hand, in the prior art, negative pressure is formed when the silk thread moves downward at high speed, resulting in cold air convection upwards; in the embodiment of the present application, since the existence of the wall portion 2031a is equivalent to reducing the inner diameter, the upward convection of cold air can be reduced, that is, it has the effect of shielding the air flow channel, thereby achieving the purpose of keeping the silk thread warm to a certain extent.

[0042] In the embodiment of the present application, the diameter D1 of the heat transfer ring 203a is adjustable, that is, when the heat transfer ring 203a is not assembled in the component hole 10 of the spinning manifold 1, the diameter D1 of the heat transfer ring 203a can be large or small, and when the heat transfer ring 203a is assembled into the component hole 10 of the spinning manifold 1, the outer diameter of the wall portion 2031a of the heat transfer ring 203a can be adjusted to be the same as the inner diameter of the inner wall 101 of the component hole 10, so that the outer surface S2 of the wall portion 2031a can be in contact with the inner wall 101 of the component hole 10 in the radial direction.

[0043] In the embodiment of the present application, the means for adjusting the diameter of the heat transfer ring 203a can be achieved by any method in the prior art. Specific adjustment methods are described below by way of example.

[0044] In the embodiments of the present application, Figure 3 As shown, the wall portion 2031a of the heat transfer ring 203a includes a first wall portion 2031a-1 and a second wall portion 2031a-2, and one circumferential end E1 of the first wall portion 2031a-1 and one circumferential end E2 of the second wall portion 2031a-2 are connected together by a first bolt B1, so that the first wall portion 2031a-1 and the second wall portion 2031a-2 can pivot around the first bolt B1, and the other circumferential end E3 of the first wall portion 2031a-1 and the other circumferential end E4 of the second wall portion 2031a-2 are connected together by two tapered lock nuts N1 and N2 opposite to each other in the up-down direction, and the two tapered lock nuts N1 and N2 are brought closer to or farther away from each other in the up-down direction by rivets R to adjust the diameter D1 of the heat transfer ring 203a.

[0045] For example, the two tapered lock nuts N1 and N2 can be at least partially accommodated in the grooves provided at the other circumferential end E3 of the first wall portion 2031a-1 and the other circumferential end E4 of the second wall portion 2031a-2. When the rivet R is tightened, the two tapered lock nuts N1 and N2 approach each other, so that the other circumferential end E3 of the first wall portion 2031a-1 and the other circumferential end E4 of the second wall portion 2031a-2 are separated from each other, so that the first wall portion 2031a-1 and the second wall portion 2031a-2 can be made to be close to each other. The outer surface of the first wall portion 2031a-1 abuts against the inner wall 101 of the component hole 10 in the radial direction, and when the rivet R is loosened, the two conical lock nuts N1 and N2 move away from each other, so that the other circumferential end E3 of the first wall portion 2031a-1 and the other circumferential end E4 of the second wall portion 2031a-2 approach each other, that is, the outer diameters of the first wall portion 2031a-1 and the second wall portion 2031a-2 are smaller than the inner diameter of the inner wall 101 of the component hole 10, thereby facilitating the removal of the heat transfer ring 203a from the component hole 10 and further facilitating disassembly.

[0046] Of course, the connection method between the first wall portion 2031a-1 and the second wall portion 2031a-2 in the present application is not limited to the above example. For example, an elastic component (for example, a spring) can also be installed at the joint between the first wall portion 2031a-1 and the second wall portion 2031a-2, so that the diameter D1 of the heat transfer ring 203a can be adjusted.

[0047] In the embodiments of the present application, Figure 2As shown, the inner diameter D2 of the wall portion 2031a is smaller than the inner diameter D3 of the bottom 2011 of the shell 201 of the spinning assembly 20; that is, the thickness requirement of the heat transfer ring 203a is: under the condition of ensuring normal production, the inner surface of the wall portion 2031a is as close to the silk thread as possible without contacting it; thereby, the heat generated by the wall portion 2031a can be further closer to the silk thread just discharged from the spinneret 202, which is further beneficial to improve the heat transfer efficiency of thermal radiation; and further plays the effect of shielding the air flow channel.

[0048] However, the present application is not limited to this, and the inner diameter D2 of the wall portion 2031a may also be the same as the inner diameter D3 of the bottom 2011 of the shell 201 of the spinning component 20; that is, the thickness of the wall portion 2031a is the radial thickness of the bottom 2011 of the shell 201 of the spinning component 20 plus the distance of the gap G1 between the shell 201 of the spinning component 20 and the inner wall 101 of the component hole 10, and the gap G1 is approximately 2 to 3 mm. Therefore, the thickness of the wall portion 2031a is approximately the radial thickness of the bottom 2011 of the shell 201 of the spinning component 20 plus 2 to 3 mm; thereby, the heat transfer ring 203a and the shell 201 of the spinning component 20 are facilitated to be integrally formed.

[0049] In the embodiment of the present application, the lower surface S2 of the wall portion 2031a is as close as possible to the heat-insulating material (not shown) at the bottom of the spinning manifold 1 and does not contact it; that is, the height requirement of the heat transfer ring 203a is: under the condition of ensuring normal production or installation, the higher the height of the heat transfer ring 203a, the better, but its bottom surface cannot contact the heat-insulating material of the spinning manifold 1. Therefore, the heat transfer ring 203a that is as high as possible can further increase the heat radiation to the filaments just discharged from the spinneret 202.

[0050] In the embodiments of the present application, Figure 3 As shown, the heat transfer ring 203a may further include a plurality of grooves 2032a, each groove 2032a being recessed from the outer surface of the wall 2031a to the inner surface of the wall 2031a, and each groove 2032a passing through the upper surface S1 and the lower surface S2 of the wall 2031a. Thus, the grooves 2032a form through holes through which the slurry (melt) can leak, and in the event of a failure of the spinning assembly 20, the overflowed melt can be discharged.

[0051] In an embodiment of the present application, the radial depth of each groove 2032a is not less than 2 mm, which is conducive to the smooth discharge of the overflowed melt; and, as shown in the figure, the number of grooves 2032a is 6, but the present application is not limited to the situation shown in the figure, for example, the number of grooves 2032a is at least 4.

[0052] In the embodiments of the present application, Figure 3As shown, the heat transfer ring 203a may also include a plurality of through holes 2033a, each of which is arranged in the wall portion 2031a along the up-down direction and passes through the upper surface S1 and the lower surface S2 of the wall portion 2031a. By providing the above-mentioned through holes, when the spinning assembly 20 fails, the top wire T1 can be inserted into the through hole 2033a to remove the heat transfer ring 203a from the spinning assembly 20. During normal production, the top wire T1 can be inserted into the through hole 2033a, for example. The number of through holes 2033a can be, for example, 4.

[0053] In the embodiment of the present application, the heat transfer ring 203a may also include an electric heating wire (not shown), which may be wound around a circumferential portion of the wall portion 2031a, or may be arranged inside the wall thickness of the wall portion 2031a, so as to further heat the heat transfer ring 203a through the electric heating wire; thereby, the heat source intensity is further improved, thereby further enhancing the heat preservation degree of the spinneret 202 and the silk thread just discharged from the spinneret 202.

[0054] In the embodiment of the present application, the heat conducting component 203 is made of metal, which is conducive to heat conduction. However, the present application is not limited thereto, and the heat conducting component 203 may also be made of other materials that are conducive to heat conduction, or made of ceramics.

[0055] In the embodiment of the present application, the heat conducting component 203 can be integrally formed with the shell 201 of the spinning assembly 20 ; or the heat conducting component 203 can also be separately formed with the shell 201 of the spinning assembly 20 .

[0056] In the embodiment of the present application, the spinning assembly 20 with the above structure can be mainly applied to fine dpf silk yarns, especially fine denier porous silk yarns with dpf≤0.5. For fine denier porous silk yarns with dpf≤0.5, the elongation can be increased by at least 3% to 4% compared with the traditional heating and heat preservation method.

[0057] According to the spinning assembly of the embodiment of the present application, the heat of the spinning assembly 20 itself is used to heat the spinneret 202 of the spinning assembly 20 through the heat conduction component 203 which is in contact with the shell 201 of the spinning assembly 20 and the assembly hole 10 of the spinning manifold 1 respectively, without the need for an additional heat source, which is beneficial to energy saving; the spinneret 202 is heated by heat conduction, which has a higher heating efficiency than the heating method by thermal radiation, and improves the quality index of the final silk thread (including elongation and strength, etc.); there is no need to integrate the heat conduction component 203 in the spinning manifold 1, which is convenient for disassembly and has a simple structure.

[0061] The above only describes the structures related to the spinning manifold in the embodiment of the present application. The present application is not limited thereto. The spinning manifold may also include other conventional structures. For details, please refer to the relevant technology, and the description is omitted here.

[0062] In this way, according to the spinning manifold 1 including the spinning assembly 20, the heat of the box itself is used to heat the spinneret 202 of the spinning assembly 20 through the heat conduction component 203 which is in contact with the shell 201 of the spinning assembly 20 and the assembly hole 10 of the spinning manifold 1 respectively, without the need for an additional heat source, which is beneficial to energy saving; the spinneret 202 is heated by heat conduction, which has a higher heating efficiency than the heating method by thermal radiation, and improves the quality index of the final silk thread (including elongation and strength, etc.); there is no need to integrate the heat conduction component 203 in the spinning manifold 1, which is convenient for disassembly and has a simple structure.
