Description

Technical Field

[0001] This utility model relates to the field of texturing machine technology, specifically an FDY stranding device for a double-strand texturing machine. Background Technology

[0002] As a key piece of equipment in the chemical fiber textile industry for producing drawn textured yarn (DTY), the core working principle of the double-strand texturing machine is to heat two strands of pre-oriented yarn (POY) in a hot box and then false-twist them using a false twister to form an elastic double-strand DTY product, meeting the demand for elastic yarns in the conventional textile industry. With the diversification of market requirements for textile performance, composite yarns combining the high strength of fully drawn yarn (FDY) and the high elasticity of DTY are gradually becoming a hot demand. Introducing FDY into the double-strand texturing machine for online twisting has become an important direction for expanding product types.

[0003] In existing technologies, achieving the combined processing of FDY and DTY on a double-strand texturing machine typically requires a separate FDY feeding and guiding system, or large-scale modifications to the core mechanical structure and control system of the texturing machine. This not only significantly increases the complexity and cost of the equipment system but may also affect the stability of the original double-strand DTY production. Furthermore, because FDY has a stable structure and does not require false twisting, the existing texturing machine's yarn path design cannot provide an independent transport channel bypassing the heating box. This easily leads to FDY losing its original high strength and low elongation characteristics due to heat, making it difficult to achieve the ideal composite of yarns with different properties. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the Invention

[0004] In view of the above shortcomings, the purpose of this utility model is to provide an FDY stranding device for a double-strand texturing machine, so as to avoid the loss of high strength and low elongation characteristics of FDY yarn due to heat due to the inability to bypass the hot box, and to ensure the product quality of FDY / DTY composite yarn.

[0005] To achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted by this utility model is as follows: An FDY stranding device for a double-strand texturing machine is characterized by comprising a base, an internal mounting cavity containing two sets of clamping assemblies, a synchronous drive unit connected to both sets of clamping assemblies, a mounting frame fixedly connected to the top of the base, a cross-shaped sliding groove extending along the length of the mounting frame, a lead screw rotatably connected within the cross-shaped sliding groove, a first motor fixedly connected to one side of the mounting frame, the output end of the first motor fixedly connected to one end of the lead screw, a cross slider threadedly connected to the lead screw and adapted to the cross-shaped sliding groove, the cross slider sliding within the cross-shaped sliding groove, a mounting plate fixedly connected to the top of the cross slider, a bracket hinged to the top of the mounting plate, a wire guide located at the end of the bracket away from the mounting plate, and an angle adjustment mechanism between the bracket and the mounting plate.

[0006] As a preferred technical solution, the clamping assembly includes a double-threaded rod rotatably connected to the inner wall of the mounting cavity. The inner wall of the mounting cavity is also fixedly connected to guide rods symmetrically distributed on both sides of the double-threaded rod. Moving plates are threadedly connected to the positive and negative thread sections of the double-threaded rod. The two moving plates are slidably connected to the two guide rods. The bottom of the base is provided with a clearance groove communicating with the mounting cavity. The bottoms of the two moving plates extend to the bottom of the base through the clearance groove and are fixedly connected to clamping plates. The synchronous drive unit is simultaneously connected to the double-threaded rods in the two clamping assemblies.

[0007] As a preferred technical solution, anti-slip pads are fixedly connected to the opposite sides of the two clamping plates in the same clamping assembly.

[0008] As a preferred technical solution, the synchronous drive unit includes a second motor fixedly connected to the inner wall of the mounting cavity, a rotating rod fixedly connected to the output end of the second motor, and the other end of the rotating rod rotatably connected to the inner wall of the mounting cavity. The middle smooth ends of the double-threaded rods in the two clamping assemblies are fixedly connected to worm gears, and worms that mesh with the two worm gears are fixedly connected to the rotating rod.

[0009] As a preferred technical solution, the angle adjustment mechanism includes a first hinge assembly fixedly connected to the top of the mounting plate, an electric push rod fixedly connected to the other end of the first hinge assembly, a second hinge assembly fixedly connected to the output end of the electric push rod, and the other end of the second hinge assembly fixedly connected to one side of the bracket.

[0010] As a preferred technical solution, the guide wire device defines a guide wire channel.

[0011] As a preferred technical solution, the anti-slip mat is made of rubber.

[0012] Compared with traditional technical solutions, the beneficial effects of this utility model are: The stranding device of this utility model, through the synchronous drive unit in the base and the cooperation of two sets of clamping components, can achieve stable installation and fixation of the device on the double-strand texturing machine. At the same time, the screw drive in the mounting frame drives the cross slider to move, and the position and angle of the guide can be flexibly adjusted in combination with the bracket and angle adjustment mechanism. This precisely constructs an independent yarn path for FDY yarn that bypasses the heat box. It does not require large-scale modification of the core structure of the texturing machine, which greatly reduces the modification cost and system complexity. It can also prevent FDY yarn from losing its high strength and low elongation characteristics due to heat, thus ensuring the product quality of FDY / DTY composite yarn. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "top," "bottom," "left," "right," "front," "rear," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances. Example

[0017] Please refer to Figures 1 to 5 As shown, an FDY stranding device for a double-strand texturing machine includes a base 1, an installation cavity 2 inside the base 1, two sets of clamping assemblies 3 inside the installation cavity 2, and a synchronous drive unit 4 connected to the two sets of clamping assemblies 3 inside the installation cavity 2. An installation frame 5 is fixedly connected to the top of the base 1. A cross slide groove 6 is provided in the installation frame 5 along the length direction. A lead screw 7 is rotatably connected in the cross slide groove 6. A first motor 8 is fixedly connected to one side of the installation frame 5. The output end of the first motor 8 is fixedly connected to one end of the lead screw 7. A cross slider 9 adapted to the cross slide groove 6 is threaded onto the lead screw 7. The cross slider 9 slides in the cross slide groove 6. An installation plate 10 is fixedly connected to the top of the cross slider 9. A bracket 11 is hinged to the top of the installation plate 10. A wire guide 12 is provided at the end of the bracket 11 away from the installation plate 10. An angle adjustment mechanism 13 is also provided between the bracket 11 and the installation plate 10.

[0018] Those skilled in the art will understand that when the first motor 8 is started, its output end drives the lead screw 7 to rotate within the cross groove 6. Since the cross slider 9 is threadedly connected to the lead screw 7 and adapted to the cross groove 6, the rotation of the lead screw 7 will drive the cross slider 9 to slide along the length of the cross groove 6. The sliding of the cross slider 9 will drive the mounting plate 10 fixedly connected to the top to move synchronously. The bracket 11 hinged to the top of the mounting plate 10 moves with the mounting plate 10, thereby adjusting the horizontal position of the wire guide 12 at the end of the bracket 11. At the same time, the angle between the bracket 11 and the mounting plate 10 can be changed through the angle adjustment mechanism 13 to realize the angle adjustment of the wire guide 12. The synchronous drive unit 4 can drive the two sets of clamping components 3 to move, so that the device is stably installed on the double-strand texturing machine.

[0019] The lead screw 7 and the cross slider 9 work together to achieve precise adjustment of the horizontal position of the wire guide 12; the angle adjustment mechanism 13 can be used to flexibly adjust the angle of the wire guide 12 to ensure that an independent wire path suitable for FDY wire can be built; the combination of two sets of clamping components 3 and synchronous drive unit 4 ensures that the device is installed firmly and avoids the wire feeding accuracy being affected by loosening during operation, providing a stable equipment foundation for online stranding of FDY and DTY. In addition, the lead screw 7 is equipped with a telescopic protective sleeve to ensure its normal and stable operation. Example

[0020] Furthermore, the clamping assembly 3 includes a double-threaded rod 301 rotatably connected to the inner wall of the mounting cavity 2. The inner wall of the mounting cavity 2 is also fixedly connected to guide rods 302 symmetrically distributed on both sides of the double-threaded rod 301. Moving plates 303 are threadedly connected to the positive and negative thread sections of the double-threaded rod 301. Both moving plates 303 are slidably connected to the two guide rods 302. The bottom of the base 1 is provided with a clearance groove 304 communicating with the mounting cavity 2. The bottoms of the two moving plates 303 extend to the bottom of the base 1 through the clearance groove 304 and are fixedly connected to clamping plates 305. The synchronous drive unit 4 is simultaneously connected to the double-threaded rods 301 in the two clamping assemblies 3.

[0021] Those skilled in the art will understand that the synchronous drive unit 4 drives the double-threaded rod 301 to rotate within the inner wall of the mounting cavity 2. Since the moving plate 303 is threadedly connected to the positive and negative thread sections of the double-threaded rod 301 respectively, and the guide rod 302 is symmetrically distributed on both sides of the double-threaded rod 301 and slidably connected to the moving plate 303, when the double-threaded rod 301 rotates, the two moving plates 303 will move towards or away from each other along the direction of the guide rod 302. The bottom of the moving plate 303 extends to the bottom of the base 1 through the clearance groove 304. Its movement will drive the clamping plate 305 fixed at the bottom to move synchronously. When the two clamping plates 305 move towards each other, they can clamp the mounting part of the double-strand texturing machine to achieve device fixation.

[0022] The forward and reverse thread design of the double-threaded rod 301 ensures that the two moving plates 303 move synchronously in opposite directions, ensuring uniform clamping force of the clamping plate 305; the guide rod 302 guides and limits the moving plate 303, preventing the moving plate 303 from rotating with the double-threaded rod 301, thus improving clamping stability; the clearance slot 304 provides space for the connection between the moving plate 303 and the clamping plate 305, making the clamping action smooth and further ensuring the installation of the device firmly. Example

[0023] Furthermore, anti-slip pads 306 are fixedly connected to opposite sides of the two clamping plates 305 within the same clamping assembly 3. The anti-slip pads 306 are made of rubber.

[0024] Those skilled in the art will understand that when the clamping plate 305 clamps the mounting part of the double-strand texturing machine, the anti-slip pad 306 will be in close contact with the mounting surface of the texturing machine. Utilizing the high frictional properties of the rubber material itself, the friction between the clamping plate 305 and the texturing machine is increased, preventing displacement of the device due to vibration or other factors during operation, and further improving the installation stability of the device. At the same time, the rubber material has a certain degree of elasticity, which can prevent the clamping plate 305 from directly and rigidly contacting the mounting surface of the texturing machine, reducing wear on the mounting part of the texturing machine, and protecting the original structure of the texturing machine. Example

[0025] Furthermore, the synchronous drive unit 4 includes a second motor 401 fixedly connected to the inner wall of the mounting cavity 2. The output end of the second motor 401 is fixedly connected to a rotating rod 402. The other end of the rotating rod 402 is rotatably connected to the inner wall of the mounting cavity 2. The middle smooth ends of the double-threaded rods 301 in the two clamping assemblies 3 are fixedly connected to worm gears 403. Worms 404 that mesh with the two worm gears 403 are fixedly connected to the rotating rod 402.

[0026] Those skilled in the art will understand that when the second motor 401 is started, its output end drives the rotating rod 402 to rotate on the inner wall of the mounting cavity 2. The two worm gears 404 fixed on the rotating rod 402 rotate synchronously with the rotating rod 402. Since the two worm gears 404 are respectively engaged with the worm wheels 403 fixed at the middle smooth end of the double-threaded rod 301 in the two sets of clamping components 3, the rotation of the worm gears 404 will drive the worm wheels 403 to rotate, thereby driving the double-threaded rod 301 to rotate synchronously, realizing the synchronous action of the two sets of clamping components 3.

[0027] The transmission method using worm gear 403 and worm 404 features a stable transmission ratio and good self-locking properties, ensuring that the double-threaded rods 301 of the two sets of clamping components 3 rotate synchronously, so that the clamping or loosening actions of the two sets of clamping plates 305 are consistent, improving the coordination during installation or disassembly of the device; the second motor 401 provides stable power, ensuring the reliable operation of the synchronous drive unit 4 and avoiding problems such as poor clamping effect due to insufficient power or unstable transmission. Example

[0028] Furthermore, the angle adjustment mechanism 13 includes a first hinge assembly 1301 fixedly connected to the top of the mounting plate 10, an electric push rod 1302 fixedly connected to the other end of the first hinge assembly 1301, a second hinge assembly 1303 fixedly connected to the output end of the electric push rod 1302, and the other end of the second hinge assembly 1303 fixedly connected to one side of the bracket 11.

[0029] Those skilled in the art will understand that when the electric push rod 1302 is activated, its output end extends or retracts, and through the rotational action of the first hinge assembly 1301 and the second hinge assembly 1303, the bracket 11 is pushed or pulled to rotate around the hinge point with the mounting plate 10, thereby changing the tilt angle of the bracket 11 and realizing the angle adjustment of the wire guide 12.

[0030] The electric actuator 1302 is easy to operate. By controlling the extension and retraction of the output end of the electric actuator 1302, the angle of the bracket 11 can be precisely adjusted, thereby precisely controlling the angle of the wire guide 12 to meet the requirements of different wire paths for the angle of the wire guide 12. The setting of the first hinge assembly 1301 and the second hinge assembly 1303 ensures that the electric actuator 1302 can smoothly drive the bracket 11 to rotate when it extends and retracts. Example

[0031] Furthermore, the wire guide 12 is made of 304 stainless steel, and the wire guide channel is polished.

[0032] Those skilled in the art will understand that when FDY wire is conveyed in the wire guide channel of the wire guide 12, the 304 stainless steel material has good corrosion resistance, which can prevent the wire guide 12 from rusting due to long-term contact with the wire or environmental factors; the polishing treatment of the inner wall of the wire guide channel reduces the roughness of the inner wall of the channel, reduces the frictional resistance between the FDY wire and the inner wall of the channel, avoids problems such as fuzzing and breakage of the wire due to friction, ensures the conveying quality of FDY wire, and provides a guarantee for high-quality stranding of FDY and DTY.

[0033] In this embodiment, the first motor 8, the second motor 401, and the electric push rod 1302 used in this application are all prior art, and the connections between the components are also prior art. Therefore, their connection relationships and principles will not be described in detail here.

[0034] The working principle and usage procedure of this device are as follows: First, move the device to the designated installation position of the double-strand texturing machine, start the second motor 401, and the output end of the second motor 401 drives the rotating rod 402 to rotate on the inner wall of the mounting cavity 2. The two worm gears 404 on the rotating rod 402 rotate synchronously. Since the worm gears 404 mesh with the worm wheels 403 at the smooth ends of the double-threaded rods 301 in the two sets of clamping components 3, the worm gears 404 drive the worm wheels 403 to drive the double-threaded rods 301 to rotate on the inner wall of the mounting cavity 2; When the threaded rod 301 rotates, the two moving plates 303 move towards each other along the symmetrically distributed guide rods 302, simultaneously driving the two clamping plates 305 to move towards each other synchronously until the rubber anti-slip pads 306 on the clamping plates 305 are in tight contact with and clamped to the mounting part of the double-strand texturing machine, thus completing the device fixation; then, according to the feeding requirements of FDY yarn, the first motor 8 is started, and the output end of the first motor 8 drives the screw 7 to rotate in the cross groove 6 of the mounting frame 5, and the cross slider 9, which is threadedly connected to the screw 7, slides along the cross groove 6. As the cross slider 9 moves, the mounting plate 10 on top of it moves with the cross slider 9, adjusting the position of the bracket 11 on top of the mounting plate 10 so that the guide wire 12 at the end of the bracket 11 is initially aligned with the FDY yarn feeding path; then the electric push rod 1302 is activated, and the output end of the electric push rod 1302 extends or retracts. Through the rotation of the first hinge assembly 1301 and the second hinge assembly 1303, the bracket 11 is pushed to rotate around the hinge point with the mounting plate 10, precisely adjusting the angle of the guide wire 12 to ensure the guide wire of the guide wire 12 is properly guided. The direction of the FDY yarn feed is perfectly matched to the direction of the FDY yarn feed. Finally, after the FDY yarn is unwound from the original yarn bobbin, it is introduced into the guide channel of the yarn guide 12. With the help of the yarn guide 12, the FDY yarn is smoothly fed to the bottom of the false twister. At the same time, the two strands of POY yarn in the double-strand texturing machine are normally heated in the hot box and false twisted by the false twister. The FDY yarn and the two strands of DTY yarn after deformation meet at the yarn guide, interweave through the network nozzle, and are wound into an FDY / DTY composite yarn bobbin by the winding device, completing the entire stranding process. If the production of composite yarn is not required, the FDY yarn feed can be stopped and the FDY yarn removed to restore the standard DTY production function of the double-strand texturing machine.
