Description

Technical Field

[0001] This utility model relates to the field of spinning production technology, specifically to a spinning production equipment for cationic dyeable polyester pre-oriented yarn. Background Technology

[0002] Cationic dyeable polyester pre-oriented yarn, as a functional and differentiated fiber, possesses unique cationic dyeability, enabling it to impart rich and vibrant colors and excellent colorfastness to fabrics. It is widely used in high-end clothing, home décor, and other fields. With the market's increasing demands for textile quality, the production process and equipment performance of cationic dyeable polyester pre-oriented yarn are also facing higher standards. Among these, tow tension control and winding quality have become key factors affecting product performance.

[0003] Reference patent (publication number: CN222251147U; publication date: 2024-12-27) discloses a spinning production equipment, relating to the field of spinning production technology, including a spinning machine. Movable plates are movably mounted on both sides of the upper surface of the spinning machine. A drive mechanism for controlling the movement of the movable plates is provided on one side of the spinning machine. A take-up roller is installed between the two movable plates. A rotation control mechanism is provided on one side of the movable plates. A lifting mechanism is also provided on the upper surface of the spinning machine. Under the meshing action between the bidirectional screw and the screw sleeve, the movable plates can be driven to move in opposite directions, thereby adjusting the distance between the two circular mounting blocks. This allows the slots on the surface of the circular mounting blocks to engage with the locking blocks on the surface of the connecting rod, fixing the position of the take-up roller. A cylinder pushes the lifting block to move, thereby lifting the take-up roller. No manual installation or disassembly of the take-up roller is required, making operation more convenient.

[0004] Based on the aforementioned patent, existing spinning production equipment requires the winding of the filament bundle after spinning. However, during winding, the tension of the filament bundle is not easy to adjust and control, which can easily affect the subsequent processing performance and the quality of the finished product. Moreover, traditional winding equipment often uses a single rotating winding shaft, and the filament bundle is fixed in the same position during the winding process, which can easily lead to problems such as the filament bundle piling up, overlapping, or uneven winding on the winding shaft. Therefore, this utility model provides a spinning production equipment for cationic dyeable polyester pre-oriented yarn. Utility Model Content

In addition, traditional winding equipment often uses a single rotating winding shaft, and the yarn bundle is fixed in the same position during the winding process, which can easily lead to the yarn bundle accumulating, overlapping or winding unevenly on the winding shaft.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spinning production device for cationic dyeable polyester pre-oriented yarn, comprising a spinning machine body, wherein the spinning machine body is provided with a winding mechanism for the spinning production of cationic dyeable polyester pre-oriented yarn, the winding mechanism comprising:

[0014] Beneficial effects

[0015] This invention provides a spinning production device for cationic dyeable polyester pre-oriented yarn. Compared with the prior art, it has the following advantages:

[0016] Firstly, the rotation of the first screw in this invention drives the lifting block to move up and down along the slide groove, thereby adjusting the height of the tension roller shaft and changing the tension of the filament bundle. If it is necessary to fine-tune the guiding position of the filament bundle, the second screw is rotated. Because the guide ring is threadedly connected to the second screw and slides in the movable groove, the rotation of the second screw causes the guide ring to slide in the movable groove, thus achieving precise adjustment of the guiding position of the filament bundle. The height of the tension roller shaft can be flexibly adjusted through the lifting assembly, achieving precise control of the filament bundle tension and avoiding filament bundle breakage or uneven thickness due to improper tension. The sliding assembly can fine-tune the guiding position of the filament bundle, ensuring the accuracy of the filament bundle transmission path and effectively correcting transmission path deviations caused by equipment installation errors, changes in the characteristics of the filament bundle itself, and other factors.

[0017] Secondly, after passing through the adjustment component, the filament enters the take-up component. The movable block slides on the slide rod, and the reciprocating screw is driven by a motor. The movable block has a protrusion inside that slides along the annular groove on the reciprocating screw, so that the movable block slides along the slide rod via the reciprocating screw, thereby driving the movable rod and the swing wheel to perform reciprocating motion. The rubber ring on the edge of the swing wheel contacts the filament. During the reciprocating motion of the swing wheel, the filament is evenly wound onto the take-up shaft. The limiting rod can limit the position of the filament to a certain extent, preventing the filament from falling off the swing wheel and avoiding the problems of filament accumulation, overlap, or uneven winding on the take-up shaft, thus improving the packaging quality and appearance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a spinning production equipment for cationic dyeable polyester pre-oriented yarn, including a spinning machine body 1, on which a winding mechanism for spinning production of cationic dyeable polyester pre-oriented yarn is provided, the winding mechanism including:

[0026] The adjustment assembly includes a mounting plate 3 fixed to the inner wall of the spinning machine body 1. The mounting plate 3 has a tension roller 304 connected by a lifting assembly inside it. The tension roller 304 has a guide ring 307 connected by a sliding assembly inside it.

[0027] The winding assembly includes a fixed plate 4 installed inside the spinning machine body 1. The fixed plate 4 has a movable rod 404 connected by a reciprocating assembly inside it. The movable rod 404 extends to one end outside the spinning machine body 1 and has a swing wheel 405 installed thereon. A rubber ring 406 is fixed to the edge of the swing wheel 405 and a limit rod 407 is fixed to the upper end of the swing wheel 405.

[0028] In a preferred embodiment, a spinneret hole 2 is provided on one side of the spinning machine body 1. A support frame 201 is provided on one side wall of the spinning machine body 1 below the spinneret hole 2. A positioning ring 202 is fixed at the upper end of the support frame 201 and is located directly in front of the spinneret hole 2. After the cationic dyeable polyester pre-oriented yarn is extruded from the spinneret hole 2 on one side of the spinning machine body 1, it passes through the positioning ring 202 at the upper end of the support frame 201 to perform preliminary positioning and guidance of the yarn bundle, ensuring stable transmission of the yarn bundle.

[0029] In a preferred embodiment, the lifting assembly includes four sets of sliding grooves 301 formed on the inner wall of the mounting plate 3. A first screw 302 is rotatably connected inside the sliding groove 301, and a lifting block 303 is slidably connected to the inner wall of the sliding groove 301. The lifting block 303 is threadedly connected to the first screw 302. A tension roller shaft 304 is located on the side wall of the lifting block 303. The sliding assembly includes a movable groove 305 formed inside the tension roller shaft 304. A second screw 306 is rotatably connected inside the movable groove 305. A guide ring 307 is slidably connected to the inner wall of the movable groove 305. The second screw 306 is threadedly connected to the guide ring 307. The yarn bundle continues to be transmitted to the adjusting assembly, first passing through the tension roller shaft 304. When it is necessary to adjust the yarn bundle tension, the first screw 302 is rotated. Since the lifting block 303 is threadedly connected to the first screw 302 and slides within the sliding groove 301, The rotation of the first screw 302 drives the lifting block 303 to move up and down along the slide groove 301, thereby adjusting the height of the tension roller shaft 304 and changing the tension of the filament bundle. If it is necessary to fine-tune the guiding position of the filament bundle, the second screw 306 is rotated. Because the guide ring 307 is threadedly connected to the second screw 306 and slides in the movable groove 305, the rotation of the second screw 306 causes the guide ring 307 to slide in the movable groove 305, thus achieving precise adjustment of the guiding position of the filament bundle. The height of the tension roller shaft 304 can be flexibly adjusted through the lifting assembly to achieve precise control of the filament bundle tension, avoiding filament bundle breakage or uneven thickness due to improper tension. The sliding assembly can fine-tune the guiding position of the filament bundle, ensuring the accuracy of the filament bundle transmission path and effectively correcting transmission path deviations caused by equipment installation errors, changes in the characteristics of the filament bundle itself, and other factors.

[0030] In a preferred embodiment, the reciprocating assembly includes a pair of support blocks 401 fixed to the upper end of a fixed plate 4. A pair of slide rods 402 are fixed to the inner wall of each support block 401. A movable block 403 is slidably connected to the outer wall of each slide rod 402. A movable rod 404 is located on the side wall of the movable block 403 and is slidably connected to the spinning machine body 1. A reciprocating screw 6 is rotatably connected inside the support block 401. A take-up shaft 5 is provided on the inner wall of the spinning machine body 1, located on one side of the swing wheel 405. The yarn bundle after passing through the adjustment assembly enters the take-up assembly. The movable block 403 slides on the slide rods 402. The reciprocating screw 6 is driven by a motor. 3. An internal protrusion is provided to slide along the annular groove on the reciprocating lead screw 6, so that the movable block 403 slides along the slide bar 402 via the reciprocating lead screw 6, thereby driving the movable rod 404 and the swing wheel 405 to perform reciprocating motion. The rubber ring 406 on the edge of the swing wheel 405 contacts the yarn bundle. During the reciprocating motion of the swing wheel 405, the yarn bundle is evenly wound on the take-up shaft 5. The limiting rod 407 can limit the position of the yarn bundle to a certain extent, so as to prevent the yarn bundle from falling off the swing wheel 405 and to prevent the yarn bundle from piling up, overlapping or winding unevenly on the take-up shaft, thereby improving the winding quality and appearance. The motor model is Y2-200L1-2Y.

[0031] The elastic buffering properties of the rubber ring 406 can also absorb the impact force caused by equipment vibration or yarn tension fluctuation during the winding process, further protecting the physical properties of the yarn.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] During operation, cationic dyeable polyester pre-oriented yarn is extruded from the spinneret 2 on one side of the spinning machine body 1 and passes through the positioning ring 202 at the upper end of the support frame 201 to complete the initial positioning and guidance, ensuring stable transmission of the yarn bundle. Subsequently, the yarn bundle enters the adjustment component. When it is necessary to adjust the tension, the first screw 302 is rotated. Under the action of the screw drive, the lifting block 303 moves up and down along the slide 301, driving the tension roller shaft 304 to change its height, thereby achieving precise adjustment of the yarn bundle tension.

[0034] To fine-tune the guide position, rotate the second screw 306 to drive the guide ring 307 to slide in the movable groove 305, accurately correcting the yarn transmission path. The adjusted yarn enters the winding assembly, and the motor drives the reciprocating screw 6 to rotate. The protrusion inside the movable block 403 slides along the annular groove of the reciprocating screw 6, making it move back and forth stably on the slide bar 402, thereby driving the movable rod 404 and the swing wheel 405 to move synchronously.

[0035] The rubber ring 406 on the edge of the swing wheel 405 contacts the filament bundle and evenly winds the filament bundle onto the take-up shaft 5 during the reciprocating process. During this process, the limiting rod 407 restricts the position of the filament bundle to prevent it from falling off. At the same time, the rubber ring 406 absorbs the impact force generated by equipment vibration and filament bundle tension fluctuations due to its elastic buffering characteristics, ensuring that the physical properties of the filament bundle are not damaged.
