Description

Technical Field

[0001] This invention relates to the field of spandex filament production technology, specifically to an automatic device and method for handling warp breakage of low-temperature, high-resilience spandex filament. Background Technology

[0002] Spandex filament, commonly known as elastic fiber or spandex fiber, is a synthetic fiber with high elasticity and elongation. It is made of polyurethane polymers containing at least 85% segments of hard and soft segments with urethane bonds directly attached to the chain. Spandex filament is so elastic that it can be stretched to 500% or more of its original length and quickly returns to its original shape.

[0003] Existing processing devices still have the following problems. Referring to a warping device for producing spandex yarn disclosed in publication number CN213978027U, it includes a transmission mechanism, a pressing mechanism, and a driving mechanism.

[0020] Beneficial effects

[0021] This invention provides an automatic device and method for handling warp breakage in low-temperature, high-resilience spandex yarn. Compared with the prior art, it has the following advantages:

[0022] (1) This processing device uses a tension sensor to detect yarn tension when the yarn passes through it during warping. When the tension sensor detects a change in yarn tension exceeding a certain range, it determines that the yarn is broken and sends a signal to stop the warping operation. At the same time, a pair of second electric telescopic rods drive a circular block to rise and fix the broken end of the yarn. A pair of first electric telescopic rods drive a first fixed plate to move. The first fixed plate drives a bidirectional threaded rod to rotate, which in turn drives another first fixed plate to move. A pair of first fixed plates drive a pair of moving plates to move relative to each other. A pair of second electric telescopic rods drive a circular block to rise and fix the yarn. An air splicer is used to adsorb and connect the broken yarn end, thus connecting the broken yarn. This allows for convenient connection processing of broken yarn.

[0023] (2) The processing device uses the second electric telescopic rod to drive the circular block to squeeze the yarn, while the circular block drives a pair of support blocks and a pair of squeezing rods to rise and fall. The pair of squeezing rods rise and fall to squeeze a pair of trapezoidal blocks. The pair of L-shaped plates drive a pair of shearing blades to move relative to each other to cut the yarn ends, keeping the yarn ends clean. This avoids loose fibers from affecting the connection of the air splicer to the yarn. The air splicer has an adsorption function, which can adsorb the yarn ends.

[0024] (3) The processing device detects tension through a tension sensor, drives the first rotating shaft and rotating wheel to rotate through a stepper motor, and drives the guide ring to rotate through the rotating wheel to adjust the tension, thereby keeping the yarn tension within a certain range and thus preventing the yarn from breaking due to tension.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-5 This invention provides a technical solution: an automatic yarn breakage treatment device and method for low-temperature high-resilience spandex yarn, comprising a rectangular shell 1, a yarn breakage treatment mechanism for connecting broken yarns inside the rectangular shell 1, the yarn breakage treatment mechanism comprising: a treatment component 2, disposed inside the rectangular shell 1 for detecting and connecting broken yarns, the treatment component 2 including a tension sensor 3, the tension sensor 3 being fixed between opposite sidewalls of the rectangular shell 1, and an air splicer 4 fixed to the inner top wall of the rectangular shell 1; an adjustment component 5, disposed inside the rectangular shell 1 for adjusting the position of the broken yarn; and a fixing component 6, disposed on the adjustment component 5 for fixing the broken yarn end, the adjustment component 5 including a sliding groove 7, the sliding groove 7 being opened at the bottom of the rectangular shell 1, and a pair of sliding joints slidably connected within the sliding groove 7. The bottom of each pair of movable blocks 8 is fixedly connected to a first fixed plate 9. A pair of first fixed plates 9 are threadedly connected to a bidirectional threaded rod 10 via a pair of threaded grooves. A pair of second fixed plates 11 are fixedly connected to the bottom of the rectangular shell 1. The bidirectional threaded rod 10 is rotatably connected between the opposite sidewalls of the pair of second fixed plates 11. A third fixed plate 12 is fixedly connected to the bottom of the rectangular shell 1. A pair of first electric telescopic rods 13 are fixedly connected to the sidewalls of the third fixed plate 12. The telescopic ends of the pair of first electric telescopic rods 13 are fixedly connected to the sidewalls of the first fixed plates 9. An arc-shaped plate 31 is fixed between the opposite sidewalls of the pair of second fixed plates 11. Each pair of first fixed plates 9 is slidably connected to the arc-shaped plate 31 via arc-shaped holes. The fixing assembly 6 includes a rectangular plate 14. A pair of rectangular plates 14 are divided into... A U-shaped through hole 15 is fixedly attached to the top of a pair of movable blocks 8. The rectangular plate 14 has an inverted U-shaped through hole 15. A first sliding groove 16 is provided on the opposite sidewalls of the U-shaped through hole 15. A circular block 17 is slidably connected to the pair of first sliding grooves 16 via a pair of first sliding blocks. A second electric telescopic rod 18 is located on the top of the movable block 8, and its output end is fixedly attached to the bottom of the circular block 17. During warping, the yarn passes through a tension sensor 3 to detect yarn tension. When the tension sensor 3 (5-9 PCS tension sensors, available from Alibaba shopping platform) detects a change in yarn tension exceeding a certain range, it determines that the yarn has broken, thus sending a signal to stop the warping operation. The time is used to drive the circular block 17 to rise through a pair of second electric telescopic rods 18, which fixes the broken end of the yarn. The first fixed plate 9 is moved through a pair of first electric telescopic rods 13. The first fixed plate 9 drives the bidirectional threaded rod 10 to rotate, which in turn drives the other first fixed plate 9 to move. The pair of first fixed plates 9 drive the pair of moving plates to move relative to each other. The circular block 17 is raised through a pair of second electric telescopic rods 18 to fix the yarn. The broken yarn end is then connected by adsorption using an air splicer 4 (model JOINTAIR115C air splicer, available for purchase from Alibaba). This allows for convenient connection of broken yarns.

[0033] In this embodiment, a pair of second sliding grooves 19 are provided on the top of the movable block 8. Each of the two second sliding grooves 19 is slidably connected to a shearing blade 20 via a second sliding block, and the two shearing blades 20 are arranged opposite to each other. An L-shaped plate 21 is fixedly connected to each of the two shearing blades 20. A trapezoidal block 22 is fixedly connected to the top of each of the two L-shaped plates 21. L-shaped blocks 23 are fixedly connected to both sides of the rectangular plate 14. A guide rod 24 is fixedly connected between the opposite sidewalls of the two L-shaped blocks 23. The two trapezoidal blocks 22 are slidably connected to the guide rod 24 through guide holes. A pair of support blocks 25 are fixedly connected to the sidewall of the circular block 17. Each support block 25 has a pressing rod 26 fixedly attached to its side wall. The second electric telescopic rod 18 drives the circular block 17 to press the yarn, while the circular block 17 drives the pair of support blocks 25 and the pair of pressing rods 26 to rise and fall. The pair of pressing rods 26 press the pair of trapezoidal blocks 22 by rising and falling. The pair of L-shaped plates 21 drive the pair of shearing blades 20 to move relative to each other to cut the yarn ends, keeping the yarn ends clean and thus preventing loose fibers from affecting the connection of the air splicer 4 to the yarn. The air splicer 4 has an adsorption function, which can adsorb the yarn ends.

[0034] In this embodiment, a stepper motor 27 is fixedly connected to the side wall of the rectangular shell 1 via an L-shaped rod. A first rotating shaft 28 is rotatably connected between the opposite side walls of the rectangular shell 1, and one end of the first rotating shaft 28 passes through the side wall of the rectangular shell 1. The output end of the stepper motor 27 is driven to one end of the first rotating shaft 28. A rotating wheel 29 is fixedly connected to the first rotating shaft 28, and a guide ring 30 is fixedly connected to the rotating wheel 29. The tension is detected by the tension sensor 3. The stepper motor 27 drives the first rotating shaft 28 and the rotating wheel 29 to rotate. The rotating wheel 29 drives the guide ring 30 to rotate to adjust the tension, thereby keeping the yarn tension within a certain range and preventing the yarn from breaking due to tension. The tension sensor 3 controls the stepper motor 27 to adjust the rotation angle.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, the equipment is installed on the warping unit at locations where yarn breakage is likely. Tension sensors 3 detect yarn tension as it passes through the yarn during warping. When the tension sensors 3 (5-9 PCS tension sensors, available from Alibaba) detect a change in yarn tension exceeding a certain range, a yarn breakage is determined, triggering a signal to stop the warping operation. Immediately, a pair of second electric telescopic rods 18 raise a circular block 17 to secure the broken yarn end. A pair of first electric telescopic rods 13 move a first fixed plate 9, which in turn rotates a bidirectional threaded rod 10. This bidirectional threaded rod 10 then moves another first fixed plate 9, which in turn moves a pair of moving plates relative to each other. The pair of second electric telescopic rods 18 raise the circular block 17 to secure the yarn. Finally, an air splicer 4 (model JOINTA) adsorbs and connects the broken yarn end. The IR115C air splicer (available for purchase on Alibaba) connects broken yarns, facilitating the reconnection of broken yarns. A second electric telescopic rod 18 drives a circular block 17 to compress the yarn, while the circular block 17 simultaneously raises and lowers a pair of support blocks 25 and a pair of compression rods 26. The compression rods 26 then compress a pair of trapezoidal blocks 22. A pair of L-shaped plates 21 drive a pair of shearing blades 20 to move relative to each other, cutting the yarn ends and keeping them clean. This prevents loose fibers from affecting the air splicer 4's yarn connection. The air splicer 4 has an adsorption function, allowing it to adhere to the yarn ends. Tension is detected by a tension sensor 3, and a stepper motor 27 drives a first rotating shaft 28 and a rotating wheel 29 to rotate. The rotating wheel 29 then drives a guide ring 30 to adjust the tension, maintaining the yarn tension within a certain range and preventing breakage due to tension.

[0037] The processing method of the automatic warping yarn breakage handling device for low-temperature high-resilience spandex yarn specifically includes the following steps:

[0038] S1: The first fixed plate 9 is moved by a pair of first electric telescopic rods 13, and the bidirectional threaded rod 10 is rotated by the first fixed plate 9, thereby the bidirectional threaded rod 10 moves the other first fixed plate 9. The pair of first fixed plates 9 move a pair of moving plates relative to each other. The circular block 17 is raised to fix the yarn by a pair of second electric telescopic rods 18. The broken yarn is connected by the air splicer 4.

[0039] S2: The second electric telescopic rod 18 drives a pair of support blocks 25 and a pair of extrusion rods 26 to rise and fall. The pair of extrusion rods 26 rise and fall to extrude a pair of trapezoidal blocks 22. The pair of L-shaped plates 21 drive a pair of shearing blades 20 to move relative to each other to shear the yarn ends.

[0040] S3: The tension is detected by the tension sensor 3, and the first rotating shaft 28 and the rotating wheel 29 are driven to rotate by the stepper motor 27. The guide ring 30 is driven to rotate by the rotating wheel 29 to adjust the tension.
