Description

Technical Field

[0001] This utility model relates to the field of polyester yarn doubling and spooling technology, specifically a polyester yarn doubling and spooling device. Background Technology

[0002] In textile production, the properties of a single yarn, such as its thickness and strength, may fluctuate. By combining multiple yarns through doubling, their respective defects can be compensated for, resulting in a more uniform yarn thickness and a more stable strength distribution. For example, combining several polyester yarns with slight differences in thickness will significantly reduce the thickness deviation of the final doubling yarn, which is beneficial for subsequent weaving processes to produce a smooth and aesthetically pleasing fabric.

[0003] Chinese Patent CN118145417B discloses a polyester yarn doubling and winding device, belonging to the field of yarn doubling and winding technology. It includes a base, a yarn bobbin assembly, a yarn guide assembly, and a winding assembly. The yarn bobbin assembly and the yarn guide assembly are fixed side-by-side on the base. A yarn rotation assembly and a yarn tensioning assembly are disposed on the base between the yarn bobbin assembly and the yarn guide assembly. A winding assembly is disposed on the base between the yarn tensioning assembly and the winding assembly. The winding assembly is connected to the yarn bobbin assembly, the yarn rotation assembly, and the winding assembly via a transmission assembly. This invention arranges the yarn bobbin assembly, the yarn rotation assembly, the yarn tensioning assembly, the yarn guide assembly, the winding assembly, and the winding assembly from left to right, and connects them using a transmission assembly, allowing them to share a single power source to achieve the purpose of doubling and winding, thus effectively saving energy.

[0004] Existing devices suffer from the problem that when the yarn on the yarn bobbins is under tension, the bobbins rotate freely. Due to inertia, some bobbins may slip, causing fluctuations in their rotational speed. This results in variations in the amount of yarn delivered. At any given time, some yarns are delivered more than others, leading to uneven thickness in the final yarn. This severely affects yarn quality, resulting in uneven fabric surfaces, noticeable patterns, or thickness differences, thus reducing the product's appearance. Furthermore, the uneven yarn delivery inevitably leads to uneven tension among the yarns. Yarns with excessive tension are prone to breakage, increasing the frequency of yarn breakage. Frequent breakage not only disrupts the production process but also leaves defects on the fabric. Yarns with insufficient tension are prone to loosening and tangling, intertwining with other yarns and further disrupting the doubling order. Moreover, loose yarns cannot tightly bind together, resulting in insufficient strength in the doubled yarn.

[0005] To address the aforementioned issues, a device for bundling and shaping polyester yarn is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a device for bundling and shaping polyester yarn, which solves the problem in the prior art where the rotation speed of the yarn bobbin is different, resulting in a certain difference in the amount of yarn released from each yarn, affecting the uniformity of bundling, and easily causing breakage or tangling.

A winding and spooling mechanism is provided on the side of the pressure roller away from the wire-coiling ring, and the winding and spooling mechanism is fixedly connected to the top of the base plate of the wire-coiling and spooling device.

[0010] Preferably, the oil outlet holes are evenly spaced about the sides of the disc-shaped rotating block, and the oil outlet holes are connected to the oil storage cavity.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model provides a polyester yarn doubling and winding device. By incorporating a synchronization component, it ensures that each yarn bobbin rotates at the same speed during the doubling process, and that each bobbin releases yarn at the same stable speed. This guarantees that each yarn is delivered to the same length, precisely achieving uniform doubling of multiple yarns. The resulting yarn is extremely uniform in thickness, eliminating localized thickness differences and significantly improving yarn uniformity. This effectively ensures the quality of the synthesized yarn. When used for weaving high-end clothing fabrics and precision industrial fabrics, it can produce high-quality fabrics with a smooth surface and fine texture. The consistent yarn release avoids strength fluctuations caused by excessive or insufficient tension in some yarns. The stable doubling process ensures tight cohesion and uniform stress between yarns, stabilizing the overall yarn strength. This allows the yarn to withstand the stretching and friction of weaving machinery during subsequent processing, such as knitting and weaving, reducing the risk of yarn breakage and ensuring production continuity.

[0023] 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.

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] Please see Figures 1 to 5 This utility model discloses a polyester yarn doubling and winding device, comprising a doubling and winding device base plate 1, a support column 2 fixedly connected to the top of the base plate 1, a servo motor 3 fixedly connected to the top of the support column 2, a first rotating shaft 7 fixedly connected to the output end of the servo motor 3, and a doubling turntable 4 fixedly connected to the end of the first rotating shaft 7 away from the servo motor 3. The first rotating shaft 7 passes through the interior of the support column 2 and is rotatably connected to the support column 2. A synchronization component 5 is installed on the side of the doubling turntable 4. The synchronization component 5 includes a second rotating shaft 501, a disc-shaped rotating block 502 fixedly connected to the end of the second rotating shaft 501, an oil storage cavity 503 is provided inside the disc-shaped rotating block 502, an oil outlet hole 504 is provided on the side of the disc-shaped rotating block 502, a toothed block 505 is fixedly connected to the outer wall of the disc-shaped rotating block 502, and a toothed chain 508 is meshed on the outside of the toothed block 505. An oil filling port 506 is fixedly connected to the side of the disc-shaped rotating block 502 away from the second rotating shaft 501, and a threaded sealing cap 507 is threadedly connected to the end of the oil filling port 506.

[0026] The oil outlet holes 504 are evenly spaced about the sides of the disc-shaped rotating block 502, and the oil outlet holes 504 are connected to the oil storage cavity 503. The toothed blocks 505 are evenly spaced about the outer wall of the disc-shaped rotating block 502, and the toothed blocks 505 and the oil outlet holes 504 are spaced apart. The second rotating shaft 501 passes through the interior of the wire-coating turntable 4, and the second rotating shaft 501 is rotatably connected to the wire-coating turntable 4.

[0027] During the unwinding process, the yarn bobbin fixed at the end of the second rotating shaft 501 will rotate along the second rotating shaft 501, carrying the disc-shaped rotating block 502. Under the constraint of the toothed chain 508, each disc-shaped rotating block 502 will maintain the same rotation speed, thus ensuring that each yarn bobbin can only rotate at the same speed. This prevents differences in the unwinding amount due to slippage or uneven rotation of individual yarn bobbins. Lubricating oil can be added to the oil storage cavity 503 through the oil filling port 506. During the rotation of the disc-shaped rotating block 502, under the action of centrifugal force, the lubricating oil can gradually flow out through the oil outlet hole 504 to the space between the toothed block 505 and the toothed chain 508, reducing wear. At the same time, the output end of the servo motor 3 drives the doubling turntable 4 to rotate through the first rotating shaft 7, causing the yarn unwinding from the yarn bobbin fixed on the side of the doubling turntable 4 to cross and wrap together, improving the tightness of the connection between the strands of yarn after doubling.

[0028] A yarn bobbin fixing assembly 6 is installed at the end of the second rotating shaft 501 away from the disc-shaped rotating block 502. The yarn bobbin fixing assembly 6 is used to fix the yarn bobbin. The yarn bobbin fixing assembly 6 includes a yarn bobbin fixing shaft 601, which is fixedly connected to the end of the second rotating shaft 501. A transmission worm 602 passes through the inside of the yarn bobbin fixing shaft 601, and the transmission worm 602 is rotatably connected to the yarn bobbin fixing shaft 601. A knob 603 is fixedly connected to the part of the transmission worm 602 that extends out of the yarn bobbin fixing shaft 601. A transmission worm wheel 604 is engaged at the top of the transmission worm 602. Two transmission screws 605 are symmetrically arranged on the side of the transmission worm wheel 604, and the threads of the two transmission screws 605 are opposite. A clamping fixing block 606 is connected to the external thread of the transmission screw 605, and the clamping fixing block 606 is slidably connected to the yarn bobbin fixing shaft 601.

[0029] The yarn spool can be fitted onto the outside of the yarn spool fixing shaft 601. Then, turn the knob 603. The knob 603 drives the transmission worm gear 602 to rotate, which in turn drives the transmission screws 605 on both sides of the transmission worm wheel 604 to rotate. Since the threads of the two transmission screws 605 are opposite, they cause the clamping blocks 606 on both sides to slide inward or extend outward at the same time. The outwardly extended clamping blocks 606 press tightly against the inner wall of the yarn spool, thereby fixing the yarn spool.

[0030] A yarn-coiling ring 8 is provided on the side of the support column 2, and the yarn-coiling ring 8 is installed on the top of the base plate 1 of the yarn-coiling and winding device. A pressure roller 10 is provided on the side of the yarn-coiling ring 8 away from the support column 2. A tensioning mechanism 9 is fixedly connected to the end of the pressure roller 10, and the tensioning mechanism 9 is fixedly connected to the top of the base plate 1 of the yarn-coiling and winding device. The tensioning mechanism 9 is used to adjust the tension of the yarn. A winding and winding mechanism 11 is provided on the side of the pressure roller 10 away from the yarn-coiling ring 8, and the winding and winding mechanism 11 is fixedly connected to the top of the base plate 1 of the yarn-coiling and winding device.

[0031] The yarns released from the yarn bobbin are wound together and passed through the hole in the middle of the doubling ring 8 to form a single thread. Then, the thread is guided by the pressure roller 10 and finally wound onto the bobbin at the winding and shaping mechanism 11 to complete the shaping.
