Description

Technical Field

[0001] This application relates to the field of twisting, and in particular to a twisting device for polyester yarn with adjustable tension and its twisting process. Background Technology

[0002] A doubling twister is a type of twisting equipment, essentially a yarn-combining device (combining multiple strands into one). It's called a yarn-combining machine, but there's no specific Chinese or English name for it. It can achieve two twists in one turn, significantly increasing twisting efficiency compared to traditional twisting equipment. It offers increased roll capacity, seamless twisting over 10,000 meters, and greatly improved twisting quality. Its lower layer height makes it particularly suitable for operation.

[0003] The final step in twisting is winding the twisted yarn onto a bobbin. A crucial point to remember during winding is to maintain a constant winding speed. This ensures stable twist and tension. However, during actual winding, the yarn diameter gradually increases as it winds onto the bobbin. At the same bobbin rotation speed, the winding speed increases with the amount of yarn wound onto the bobbin, thus affecting the twist. Current twisting devices relying solely on a tension wheel to maintain stable yarn tension are clearly insufficient, and adjusting the existing tension wheel is also inconvenient.

[0004] Therefore, we use this twisting device to solve the problem of unstable tension during yarn winding in the prior art. Summary of the Invention

[0005] The purpose of this application is to improve the existing twisting device and provide an adjustable polyester yarn twisting device and twisting process compared to the existing technology. By adding a yarn feeder to the existing twisting device to achieve uniform winding, the stability of yarn tension is effectively improved. Furthermore, by setting convex and concave yarn discs, the yarn is bent at a certain arc, thereby tightening the yarn. The magnitude of magnetic repulsion is indirectly adjusted by adjusting the flexible magnetic shielding sheet, thereby changing the distance between the convex and concave yarn discs to adjust the yarn tension. At the same time, the convex and concave yarn discs cooperate with the yarn feeder to ensure that the yarn is not affected by the speed of the yarn bobbin during winding, effectively improving the stability of yarn twist.

[0006] This achieves stability of tension and twist during yarn winding, thereby effectively reducing the impact of yarn drum rotation speed on the yarn.

[0007] Furthermore, the clamping bar includes a bar body, with a polyurethane elastic mesh fixedly connected to the end of the bar body away from the anti-over-clamping component. A plastic seat is fixedly connected to the polyurethane elastic mesh, and a magnetic sheet is fixedly embedded in the inner wall of the plastic seat. A clamping head is also fixedly connected to one end of the plastic seat. When the two wire feeders rotate synchronously, the magnetic sheets on the two opposing clamping bars attract each other, causing the clamping bars to contact the polyester yarn. This allows the opposing clamping heads to clamp the polyester yarn, thereby achieving the purpose of uniformly conveying the twisted polyester yarn. The elasticity of the polyurethane elastic mesh can effectively prevent the clamping force of the two clamping heads on the polyester yarn from being too large, which could cause yarn breakage.

[0008] Furthermore, a yarn clamping pad is fixedly embedded in the side wall of the yarn clamping head. The yarn clamping pad is made of latex material, which is soft and has sufficient friction. In this way, the yarn clamping pad can move the polyester yarn by friction without damaging it.

[0009] Furthermore, the two wire feeders rotate synchronously in opposite directions, and the two opposing magnetic plates attract each other. When the two opposing magnetic plates rotate into a straight line, the magnetic attraction between them allows the two clamping rods to clamp the polyester filament, thereby achieving the conveying of the polyester filament. Moreover, the two clamping rods rotate at the same speed, which can effectively improve the tension and twist stability during the winding process of the polyester filament.

[0010] Furthermore, the anti-over-clamping component includes a rubber matrix, and multiple tendon-shaped latex inserts are fixedly embedded in the inner wall of the rubber matrix. When the clamping rods approach each other due to magnetic attraction and clamp the polyester filament, the anti-over-clamping component is pulled. Both the rubber matrix and the tendon-shaped latex inserts are elastic, so they can reset the clamping rods and restrain the two clamping rods from over-clamping the polyester filament.

[0011] Furthermore, the reset adjustment component includes a rubber bladder, inside which are placed multiple vertically arranged silicone rings, and a spring wire is fixedly connected between two adjacent silicone rings. Both the silicone rings and the spring wire have elasticity, which allows the convex coil to reset, making it convenient to adjust the tension of the convex and concave coils on the polyester yarn.

[0012] Optionally, the magnetic adjustment cover includes a magnetic shielding cover. Adjustment grooves are provided on both sides of the magnetic shielding cover, and flexible magnetic shielding sheets are slidably connected within these grooves. Two flexible magnetic shielding sheets pass through the rear of the magnetic shielding cover and exit from the front. Matching concave-convex sealing strips are fixedly connected to the front ends of the two flexible magnetic shielding sheets. When the position of the flexible magnetic shielding sheets within the magnetic shielding cover is adjusted, the area of ​​the magnetic component covered by the front end of the flexible magnetic shielding sheet changes accordingly, thereby altering the magnitude of the magnetic repulsion force of the magnetic component on the disk. This, in turn, changes the position of the convex wire disk recessed into the concave wire disk, thus adjusting the tension of the polyester filament. The concave-convex sealing strips effectively enhance the magnetic shielding effect of the flexible magnetic shielding sheets when the two flexible magnetic shielding sheets are joined.

[0013] Furthermore, the magnetic assembly is composed of multiple magnetic blocks, which are spaced apart. The side wall of the slide plate is fixedly embedded with a disk that repels the magnetic blocks. The multiple magnetic blocks are spaced apart so that a single magnetic block can be covered when adjusting the flexible magnetic shielding sheet, thereby facilitating the adjustment of the magnetic repulsion force of the magnetic assembly on the disk.

[0014] Furthermore, a yarn storage reel is fixedly connected to the mounting base near the yarn bobbin, and the yarn storage reel has threading ports on both sides of the center line. A twist stabilizing cylinder is rotatably connected to the center of the yarn storage reel, and the polyester yarn is wound around the twist stabilizing cylinder multiple times. The twisted polyester yarn wound around the twist stabilizing cylinder can effectively improve the tension and twist stability before winding, and can effectively avoid the influence of the yarn bobbin winding speed on the twist of the polyester yarn.

[0015] Furthermore, the twisting process of a polyester yarn twisting device with adjustable tension includes the following twisting steps:

[0016] S1. First, turn on the twisting machine to twist the polyester yarn. After the initial twisting, pass the polyester yarn through the cam disc, the concave disc and the yarn feeder in sequence. Then, after the twist stabilizing cylinder has been turned around once, place it on one side of the yarn bobbin and pull the polyester yarn by hand to keep it moving at a certain speed.

[0017] S2, start the servo motor to make the yarn feeder rotate. The two yarn feeders rotate synchronously in opposite directions. During this process, the two yarn feeders will uniformly feed the twisted polyester yarn towards the yarn bobbin, effectively maintaining the stability of the tension and twist of the polyester yarn during the winding process.

[0018] S3. Next, move the flexible magnetic shielding sheet back and forth to adjust the magnitude of the magnetic repulsion force of the magnetic component on the disk, thereby adjusting the tension of the polyester filament on the convex and concave coils. After the tension is adjusted, cut off the polyester filament that was pulled out by hand in step S, and then wind the new polyester filament onto the yarn bobbin for winding.

[0019] Compared to existing technologies, the advantages of this application are:

[0020] (1) This solution improves the stability of yarn tension by adding a yarn feeder to the existing twisting device to achieve uniform winding. It also bends the yarn to a certain degree by setting convex and concave yarn discs, thereby tightening the yarn. The magnetic repulsion force is indirectly adjusted by adjusting the flexible magnetic shield, thereby changing the distance between the convex and concave yarn discs and thus adjusting the yarn tension. At the same time, the convex and concave yarn discs cooperate with the yarn feeder to ensure that the yarn is not affected by the speed of the yarn drum during winding, effectively improving the stability of yarn twist and achieving the stability of tension and twist during yarn winding, thereby effectively reducing the influence of the yarn drum speed on the yarn.

[0021] (2) The clamping bar includes a bar body. A polyurethane elastic mesh is fixedly connected to the end of the bar body away from the anti-over-clamping device. A plastic seat is fixedly connected to the polyurethane elastic mesh. A magnetic sheet is fixedly embedded in the inner wall of the plastic seat. A clamping head is also fixedly connected to one end of the plastic seat. When the two wire feeders rotate synchronously, the magnetic sheets on the two clamping bars on opposite sides attract each other, causing the clamping bars to contact the polyester yarn. This allows the opposite clamping heads to clamp the polyester yarn, thereby achieving the purpose of uniformly conveying the twisted polyester yarn. The elasticity of the polyurethane elastic mesh can effectively prevent the clamping force of the two clamping heads on the polyester yarn from being too large, which would cause yarn breakage.

[0022] (3) A wire clamping pad is fixedly embedded on the side wall of the wire clamping head. The wire clamping pad is made of latex material. Latex is soft and has sufficient friction. In this way, the wire clamping pad can move the polyester filament by relying on friction without damaging it.

[0023] (4) The two wire feeders rotate synchronously and in opposite directions. The two opposing magnetic plates attract each other. When the two opposing magnetic plates rotate to a straight line, the two clamping rods clamp the polyester wire by relying on the magnetic attraction between them, thereby realizing the conveying of the polyester wire. Moreover, the two clamping rods rotate at the same speed, which can effectively improve the tension and twist stability during the winding process of the polyester wire.

[0024] (5) The anti-over-clamping component includes a rubber matrix, and multiple tendon-shaped latex inserts are fixedly embedded in the inner wall of the rubber matrix. When the clamping rods approach each other due to magnetic attraction and clamp the polyester filament, the anti-over-clamping component is pulled. Both the rubber matrix and the tendon-shaped latex inserts are elastic, so the clamping rods can be reset and the two clamping rods can be restrained from over-clamping the polyester filament.

[0025] (6) The reset adjustment component includes a rubber bladder, inside which are placed multiple vertically arranged silicone rings, and a spring wire is fixedly connected between two adjacent silicone rings. Both the silicone rings and the spring wire have elasticity, which allows the convex coil to reset and facilitates adjustment of the tension of the convex and concave coils on the polyester yarn.

[0026] (7) The magnetic force adjustment cover includes a magnetic shielding cover. Adjustment grooves are provided on both sides of the magnetic shielding cover, and flexible magnetic shielding sheets are slidably connected in the adjustment grooves. Two flexible magnetic shielding sheets are inserted into the rear of the magnetic shielding cover and exited from the front. The front ends of the two flexible magnetic shielding sheets are respectively fixedly connected with matching concave and convex sealing strips. When the position of the flexible magnetic shielding sheet in the magnetic shielding cover is adjusted, the area of ​​the magnetic component covered by the front end of the flexible magnetic shielding sheet will change accordingly, thereby changing the magnitude of the magnetic repulsion force of the magnetic component on the disk, and thus changing the position of the convex wire disk recessed into the concave wire disk, thereby realizing the adjustment of the tension of the polyester yarn. The concave and convex sealing strips can effectively improve the magnetic shielding effect of the flexible magnetic shielding sheet when the two flexible magnetic shielding sheets are connected.

[0027] (8) The magnetic assembly is composed of multiple magnetic blocks, and the multiple magnetic blocks are spaced apart. The side wall of the slide plate is fixedly embedded with a disk that repels the magnetic blocks. The multiple magnetic blocks are spaced apart so that a single magnetic block can be covered when adjusting the flexible magnetic shielding sheet, thereby facilitating the adjustment of the magnetic repulsion force of the magnetic assembly on the disk.

[0028] (9) A yarn storage reel is fixedly connected to the mounting base near the yarn bobbin, and the yarn storage reel is located on both sides of the center line with threading ports. A twist stabilizing cylinder is rotatably connected to the middle of the yarn storage reel, and the polyester yarn is wound around the twist stabilizing cylinder multiple times. The twisted polyester yarn wound around the twist stabilizing cylinder can effectively improve the tension and twist stability before winding, and can effectively avoid the influence of the yarn bobbin winding speed on the twist of the polyester yarn.

Detailed Implementation

[0039] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0040] Example 1:

[0041] Please refer to an adjustable polyester yarn twisting device. Figure 1 , 2 and Figure 3 The system includes a twisting machine body and a yarn bobbin on it. A mounting base 1 is provided between the yarn bobbin and the guide hook on the twisting machine body. Two yarn feeders 2 are symmetrically distributed on both sides of the polyester yarn in the middle of the mounting base 1. Two servo motors with their output ends connected to the yarn feeders 2 are installed at the bottom of the mounting base 1 (the specific connection structure and control principle are known technologies to relevant technicians, and the specific model is selected according to actual needs, and will not be described in detail here). The yarn feeder 2 includes a rotating roller 201, and the side wall of the rotating roller 201 has multiple equal... The device features a series of interconnected telescopic grooves, each slidably connected to a wire clamping rod 202. Each wire clamping rod 202 includes a rod body 2021. A polyurethane elastic mesh 2022 is fixedly connected to the end of the rod body 2021 furthest from the anti-over-clamping component 2023. A plastic seat 2023 is fixedly connected to the polyurethane elastic mesh 2022. A magnetic sheet 2024 is fixedly embedded in the inner wall of the plastic seat 2023. A wire clamping head 2025 is also fixedly connected to one end of the plastic seat 2023. When the two wire feeders 2 rotate synchronously, the two opposing wire clamping rods 2022... The magnetic plates 2024 on the 2nd plate attract each other, causing the clamping rods 202 to contact the polyester yarn. This allows the opposing clamping heads 2025 to hold the polyester yarn, thus achieving uniform feeding of the twisted polyester yarn. The elasticity of the polyurethane elastic net 2022 effectively prevents excessive clamping force from the two clamping heads 2025, which could cause yarn breakage. Clamping pads 2026 are fixedly embedded in the side walls of the clamping heads 2025. These pads are made of latex, which is soft and has sufficient friction. The sample clamping pad 2026 can move the polyester yarn by friction without damaging it. The two yarn feeders 2 rotate synchronously and in opposite directions. The two opposing magnetic plates 2024 are magnetically attracted to each other. When the two opposing magnetic plates 2024 rotate into a straight line, the magnetic attraction between them allows the two clamping rods 202 to clamp the polyester yarn, thereby realizing the conveying of the polyester yarn. Moreover, the two clamping rods 202 rotate at the same speed, which can effectively improve the tension and twist stability of the polyester yarn during the winding process.

[0042] Please see Figure 4Furthermore, an anti-over-clamping component 203 is fixedly connected between the clamping rod 202 and the wall of the telescopic groove. The anti-over-clamping component 203 includes a rubber substrate 2031, and multiple tendon-shaped latex inserts 2032 are fixedly embedded in the inner wall of the rubber substrate 2031. When the clamping rods 202 approach each other due to magnetic attraction and clamp the polyester filament, the anti-over-clamping component 203 is pulled. Both the rubber substrate 2031 and the tendon-shaped latex inserts 2032 are elastic, so the clamping rods 202 can be reset and the two clamping rods 202 can be restrained from over-clamping the polyester filament.

[0043] Please see Figure 1 , 6 and Figure 8 The mounting base 1 is fixedly connected to a tension adjusting seat 3 on one side of the yarn feeder 2. A sliding plate 301 is slidably connected to the tension adjusting seat 3. Multiple symmetrically distributed reset adjusting components 4 are fixedly connected between the side wall of the sliding plate 301 and the inner wall of the tension adjusting seat 3. The reset adjusting component 4 includes a rubber bladder 401. Multiple vertically arranged silicone rings 402 are placed inside the rubber bladder 401, and a spring wire 403 is fixedly connected between two adjacent silicone rings 402. Both the silicone rings 402 and the spring wire 403 have elasticity, which allows the convex yarn disc 5 to reset, making it convenient to adjust the tension of the convex yarn disc 5 and the concave yarn disc 6 on the polyester yarn. The sliding plate 301 is fixedly connected to the side wall away from the reset adjusting component 4. There is a convex coil 5, and a concave coil 6 matching the convex coil 5 is fixedly connected to the mounting base 1. Polyester yarn passes through the convex coil 5 and the concave coil 6, and passes through two yarn feeders 2 and is wound on the yarn bobbin. A magnetic adjustment cover 7 is fixedly connected to the inner wall of the tension adjustment seat 3, and a magnetic component 8 that magnetically repels the slide plate 301 is fixedly connected inside the magnetic adjustment cover 7. The magnetic component 8 is composed of multiple magnetic blocks, and the multiple magnetic blocks are spaced apart. A disk 3011 that repels the magnetic blocks is fixedly embedded in the side wall of the slide plate 301. The multiple magnetic blocks are spaced apart so that a single magnetic block can be covered when adjusting the flexible magnetic shielding sheet 702, thereby facilitating the adjustment of the magnitude of the magnetic repulsion force of the magnetic component 8 on the disk 3011.

[0044] Example 2:

[0045] Based on Example 1, please refer to Figure 6 , 7The magnetic force adjustment cover 7 includes a magnetic shielding cover 701. The magnetic shielding cover 701 has adjustment grooves on both sides, and flexible magnetic shielding sheets 702 are slidably connected in the adjustment grooves. The two flexible magnetic shielding sheets 702 are inserted into the rear of the magnetic shielding cover 701 and exit from the front. The front ends of the two flexible magnetic shielding sheets 702 are respectively fixedly connected with matching concave and convex sealing strips 703. When the position of the flexible magnetic shielding sheet 702 in the magnetic shielding cover 701 is adjusted, the area of ​​the front end of the flexible magnetic shielding sheet 702 covering the magnetic component 8 will change accordingly, thereby changing the magnitude of the magnetic repulsion force of the magnetic component 8 on the disk 3011, and thus changing the position of the convex wire disk 5 recessed into the concave wire disk 6, thereby realizing the adjustment of the tension of the polyester yarn. The concave and convex sealing strips 703 can effectively improve the magnetic shielding effect of the flexible magnetic shielding sheet 702 when the two flexible magnetic shielding sheets 702 are connected.

[0046] Please see Figure 1 The mounting base 1 is also fixedly connected to a yarn storage reel 9 near the yarn bobbin. The yarn storage reel 9 has threading ports on both sides of the center line. The center of the yarn storage reel 9 is rotatably connected to a twist stabilizing cylinder 10. The polyester yarn is wound around the twist stabilizing cylinder 10 multiple times. The twisted polyester yarn wound around the twist stabilizing cylinder 10 can effectively improve the tension and twist stability before winding, and can effectively avoid the influence of the yarn bobbin winding speed on the twist of the polyester yarn.

[0047] Please see Figure 1 , 2 5 and Figure 7 The twisting process of this device includes the following twisting steps:

[0048] S1. First, turn on the twisting machine to twist the polyester yarn. After the initial twisting, the polyester yarn that comes out will pass through the convex disc 5, the concave disc 6 and the yarn feeder 2 in sequence. Then, after the twist stabilizer 10 is wrapped around the yarn 3-6 times, it will be placed on one side of the yarn bobbin. Pull the polyester yarn by hand to keep it moving at a certain speed.

[0049] S2, start the servo motor to make the yarn feeder 2 rotate. The two yarn feeders 2 rotate synchronously in opposite directions. During this process, the two yarn feeders 2 will uniformly feed the twisted polyester yarn towards the yarn bobbin, effectively maintaining the stability of the tension and twist of the polyester yarn during the winding process.

[0050] S3. Next, move the flexible magnetic shielding sheet 702 back and forth to adjust the magnitude of the magnetic repulsion force of the magnetic component 8 on the disk 3011, thereby adjusting the tension of the polyester yarn on the convex and concave discs 5 and 6. After the tension is adjusted, cut off the polyester yarn pulled out by hand in step S1, and then wind the new polyester yarn onto the yarn bobbin for winding.

[0051] The above description is only the best implementation method adopted in this application in combination with current practical needs, but the scope of protection of this application is not limited thereto.
