Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of spinning devices and relates to a spinning component. Background Art
[0002] The components of polyester industrial yarn need to be replaced periodically. When the production line stops, the components also need to be removed. The removed components need to be disassembled by component workers in a hot state, and then cleaned and other operations are carried out for reassembly and use.
[0003] In the early production of industrial yarn, single-head spinning was used. The components used were single-cavity spinning components (that is, one ingot component corresponded to a bundle of filaments). It was only necessary to press the inner core of the component under a press, then use a wrench to separate the fastening ring from the shell, then lift the inner core of the component out of the shell, and then use a brass flat bar to pry open the upper cover, distribution plate, spinneret plate, etc. It was very easy to complete the disassembly.
[0004] However, with the rapid development of polyester industrial yarn, single-head spinning has problems such as low production efficiency and poor flexibility. Therefore, multi-head spinning is also increasingly used. One of the components used in multi-head spinning is a double-cavity spinning component (that is, one ingot component corresponds to two bundles of filaments). Due to the special structural design of the double-cavity spinning component, its internal components will be tightly combined with the shell due to high-temperature expansion under hot conditions. Even under the pressure of a press, it is difficult to separate the fastening ring from the shell with a wrench, and it needs to be left to cool before disassembly. Therefore, for double-cavity spinning components, they are mostly disassembled after standing and cooling (cold disassembly). This not only wastes a lot of time, but also there are relatively large safety hazards during the cold disassembly process. Because the melt is cold-set during this process, a copper rod needs to be used to knock on the inner core of the component to separate other accessories, so there are accessory damages or personnel injuries, and this disassembly method has low efficiency.
[0005] Therefore, it is necessary to propose a double-cavity spinning component that is easy to disassemble thermally to improve the disassembly efficiency of the component. Summary of the Utility Model
[0006] The purpose of the utility model is to solve the problems existing in the prior art and provide a spinning component.
[0007] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0008] A spinning component includes a component shell and a circular spinneret plate. The spinneret plate is horizontally placed in the component shell. The spinneret plate is divided into upper and lower parts. The upper part extends radially outward along the spinneret plate to form an extension part. The extension part is supported by an annular boss fixed in the component shell. An annular gasket is arranged between the extension part and the annular boss;
[0009] The vertical section of the annular gasket is trapezoidal;
[0010] The height of the trapezoid is 1 - 3 mm;
[0011] The annular gasket is a copper gasket or an aluminum gasket;
[0012] Because the sizes of the upper surface and the lower bottom ring of this annular gasket are different, when disassembling the spinning component, by pressing down the inner core of the component with a press (a fastening ring is provided at the top of the component housing and is threadedly connected to the component housing for tightly binding the inner core of the component within the component housing. The inner core of the component is a series of components located within the component housing, and the lowermost end thereof is a spinneret plate), the annular gasket has a certain ductility and deformation space in the horizontal direction, so that the thickness of the gasket in the vertical direction is reduced, and the inner core of the component can have a downward movement space. Furthermore, there is a gap between the uppermost end of the inner core of the component and the fixing ring, which facilitates the removal of the fixing ring. The thickness of the annular gasket should not be too large, otherwise it will affect the installation and sealing performance. Otherwise, it should not be too small either, otherwise it will not function.
[0013] As a preferred technical solution:
[0014] For a spinning component as described above, the acute angle of the trapezoid is 25 - 29°.
[0015] For a spinning component as described above, the upper base (i.e., the shorter base) of the trapezoid is located above the lower base (i.e., the longer base).
[0016] For a spinning component as described above, the length of the lower base of the trapezoid is equal to the width of the extension part.
[0017] For a spinning component as described above, the width of the extension part is 0.8 - 1.2% of the radius of the lower part of the spinneret plate.
[0018] For a spinning component as described above, the trapezoid is an isosceles trapezoid.
[0019] For a spinning component as described above, the height of the trapezoid is 2 mm, the length of the upper base is 7.5 mm, and the length of the lower base is 15 mm.
[0020] For a spinning component as described above, the spinning component is a double - cavity spinning component.
[0021] Beneficial effects:
[0022] The present utility model can achieve the disassembly of the double - cavity spinning component under hot conditions, improve the disassembly efficiency of the component, and avoid damage to the component caused by violent disassembly during the disassembly process, reduce the maintenance cost, avoid work - related injuries, and reduce potential safety hazards.

[0028] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of this application.
[0029] A spinning pack, which is a double - cavity spinning pack. As Figures 1 to 4 shown, it includes a pack housing 3 and a circular spinneret plate 2. The spinneret plate 2 is horizontally placed in the pack housing 3. The spinneret plate 2 is divided into upper and lower parts. The upper part extends radially outward along the spinneret plate 2 to form an extension part. The extension part is supported by an annular boss fixed in the pack housing 3. An annular gasket 1 is arranged between the extension part and the annular boss;
[0030] The width of the extension part is 1.2% of the radius of the lower part of the spinneret plate 2;
[0031] As Figure 2 shown, the vertical section of the annular gasket 1 is an isosceles trapezoid. The upper base is located above the lower base. The height of the isosceles trapezoid is 2 mm, the length of the upper base is 7.5 mm, and the length of the lower base is 15 mm;
[0032] The length of the lower base of the isosceles trapezoid is equal to the width of the extension part;
[0033] The annular gasket 1 is a copper gasket or an aluminum gasket.
[0034] The using process of the above - mentioned device is as follows: When disassembling the spinning pack in a hot state, use a press to press down the inner core of the pack. Because the annular gasket has a certain ductility and deformation space in the horizontal direction, the thickness of the gasket in the vertical direction can be reduced, and the inner core of the pack can have a moving space downward. As a result, there is a gap between the uppermost end of the inner core of the pack and the fixing ring 4, which is convenient for removing the fixing ring 4. After removing the fixing ring 4, the inner core of the pack can be taken out from the pack housing 3.
