Description

Technical Field

[0001] The utility model relates to the technical field of fiber textile machinery, in particular to a spinneret for producing differentiated regenerated polyester fibers. Background Art

[0002] Differentiated fibers generally refer to fibers that have undergone physical, chemical, or process modifications based on their original fiber composition to improve the overall performance of conventional synthetic fibers, resulting in significantly different morphological structures and physical and chemical properties from those of conventional chemical fibers, thereby enhancing their quality and grade. Differentiated fibers are a relatively common type of fiber. During their production, differentiated fibers typically require the use of a spinneret to extrude the fiber raw material for subsequent processing and use. Traditional spinnerets, however, have a relatively simple structure and lack internal heating for the raw material, which can easily cause the fiber raw material to solidify rapidly within the spinneret, leading to blockage and thus affecting the spinning efficiency and quality of the fibers, making them inconvenient for normal spinning. Furthermore, the spinneret requires regular cleaning and maintenance. However, existing spinnerets are typically sealed or even welded to improve the sealing effect of the structure. These existing fixing methods are inconvenient for cleaning and maintenance, increase the difficulty, and are inefficient to install, requiring repeated adjustments, which is not conducive to efficient production. Therefore, further improvements are needed. Utility Model Content

[0021] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0022] like Figures 1 to 3 As shown, a spinneret for the production of differentiated regenerated polyester fibers comprises a spinneret body 1, which is cylindrical and has a plurality of spinneret holes 2 extending through the thickness of the body on its upper end face. The plurality of spinneret holes 2 are arranged in a circular circle with the center of the spinneret body 1 as the center and are equidistant from each other. The longitudinal center cross-section of each spinneret hole 2 is a bullet-shaped structure that is wide at the top and narrow at the bottom, and a guide block 3 is fixedly installed in each spinneret hole 2. The structure of the guide block 3 is the same as that of the spinneret hole 2, and it is fixed on the inner wall of the spinneret hole 2. The guide block 3 is hollow inside and is mainly used to guide the fiber raw material into the spinneret hole 2 and ensure that the fiber raw material maintains the correct path and direction when passing through the spinneret hole 2, thereby reducing the friction between the fiber raw material and the spinneret hole 2, thereby reducing the risk of fiber damage and breakage.

[0023] A heating mechanism is provided at the bottom of the spinneret body 1, which includes a plurality of concentric annular mounting grooves 4 arranged at the bottom of the spinneret body 1, an annular heating block 5 fixedly installed in the corresponding annular mounting grooves 4, a plurality of heat-conducting blocks 6 and a plurality of power boxes 7, wherein the plurality of annular mounting grooves 4 are arranged at equal intervals and are alternately arranged in layers with the above-mentioned annularly arranged spinneret holes 2, and the spinneret holes 2 are located between two adjacent annular mounting grooves 4; the annular heating blocks 5 are installed one by one in the annular mounting grooves 4, and a plurality of embedded grooves are provided in the spinneret body 1 above them, and the above-mentioned plurality of heat-conducting blocks 6 are installed one by one in the embedded grooves and fixed thereto, and the lower end of the heat-conducting block 6 is fixedly connected to the top of the annular heating block 5, and the upper end thereof is fixedly connected to the corresponding guide block 3, and the above-mentioned heat-conducting block 6 and the guide block 3 are both made of heat-conducting metal material, which can realize heat conduction, and the fiber raw material in the guide spinning process is heated in real time through the guide block 3. The above-mentioned multiple power supply boxes 7 are fixedly installed at the peripheral position of the bottom of the spinneret body 1 to prevent the spinneret holes 2 from being blocked from spinning. They are respectively connected to each annular heating block 5 through lines to provide them with electric energy for heating.

[0024] The heat conducting block 6 is arranged in an L-shaped structure, so that the annular heating block 5 in the outer circle is connected to the guide block 3 in the spinneret hole 2 in the adjacent inner circle, thereby improving the heating radiation efficiency.

[0025] The spinneret body 1 also features four symmetrically spaced retractable connectors on its circumferential sidewalls for quick installation and removal within the corresponding fiber spinning equipment. Four corresponding inset rectangular cavities 8 are defined within the spinneret body 1's circumferential sidewalls, corresponding to the locations where the retractable connectors are mounted. Each cavity 8 has an extension opening on its outer wall. The above-mentioned retractable card joint is accommodated in the corresponding rectangular cavity 8, and specifically includes a vertical movable plate 9, two horizontally extending plates 11, a magnetic block 12, a traction rope 13 and a telescopic spring 10. The vertical movable plate 9 is slidably installed in the corresponding rectangular cavity 8, and a telescopic spring 10 is arranged between its inner side wall and the inner end side wall of the rectangular cavity 8, and the two ends of the telescopic spring 10 are respectively fixedly connected to it; the above-mentioned two horizontally extending plates 11 are both fixedly installed laterally on the outer side wall of the vertical movable plate 9, one above and one below, and arranged in parallel, and their outer ends can extend outward from the corresponding extension port to the rectangular cavity 8; the magnetic block 12 is fixedly installed on the inner side of the outer end side wall of the rectangular cavity 8, and an electromagnetic magnet is selected, which is connected to the above-mentioned power box 7 through a line. Correspondingly, the above-mentioned vertical movable plate 9 is made of magnetic metal material, such as iron. After power is turned on, the electromagnetic magnet can generate suction on the vertical movable plate 9. One end of the traction rope 13 is fixedly connected to the inner wall of the vertical movable plate 9, and the other end passes through the spinneret body 1 inwardly and upwardly and extends from the upper end surface of the spinneret body 1, with a pull ring connected to the end.

[0026] The interior of the fiber spinning production equipment is provided with a snap-in groove corresponding to the horizontal extension plate 11 in the four retractable snap-in joints, and the outer end of the horizontal extension plate 11 can be inserted into the corresponding snap-in groove. When guiding the spinning, the annular heating block 5 is connected to the power box 7, and the power is turned on for heating. The heat is transferred through the heat-conducting block 6 and the guide block 3, so that the temperature around the guide block 3 increases, and the fiber raw material inside it is heated in real time, ensuring the connectivity during fiber spinning and improving the quality of fiber spinning; at this time, the magnetic suction block 12 is energized, and the electromagnetic suction generates suction on the vertical movable plate 9, driving it to slide outward along the rectangular cavity 8, thereby driving the horizontal extension plate 11 to extend outward, completing the stable snap-in of the spinneret body 1. When the spinning is completed, the magnetic block 12 is powered off, and the vertical movable plate 9 is reset under the action of the telescopic spring 10. At this time, the outer end of the horizontally extending plate 11 has not yet disengaged from the card slot, and continues to ensure the stable card connection of the spinneret body 1. Subsequently, the traction rope 13 is pulled to drive the vertical movable plate 9 to continue to slide inward, thereby driving the horizontally extending plate 11 to retract into the rectangular cavity 8, completing the disengagement and realizing quick disassembly, which is convenient for subsequent cleaning, maintenance and replacement.

[0027] According to a further optimized technical solution, the guide block 3 can be provided with a variety of different inner diameter specifications. By replacing the guide blocks 3 with different inner diameters, the spinning production of fibers with different aperture requirements can be achieved, which can effectively increase the practicality of the spinneret.

[0028] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
