Abstract
Description
Technical Field
[0001] This invention relates to the field of composite yarn twisting technology, specifically to a composite yarn twisting processing device and a method for preparing sunscreen yarn. Background Technology
[0002] Composite yarn twisting equipment is a key piece of equipment in the textile industry used to produce yarns with special properties. Composite yarns are typically made by combining two or more fibers with different properties through specific processing methods to achieve a combination of properties, such as the luster and strength of filaments and the softness and warmth of staple fibers. These yarns are widely used in clothing, home textiles, and other fields, meeting diverse market demands. Twisting is a crucial step in the production of composite yarns, affecting not only the appearance quality of the yarn but also the performance of the final product. Traditional twisting methods are often inefficient and fail to meet the modern textile industry's pursuit of high efficiency and high quality. Therefore, the research and development of composite yarn twisting equipment has become essential for improving production efficiency, reducing costs, and enhancing product quality.
[0003] In recent years, with the continuous advancement of textile technology, composite yarn twisting processing equipment has also been developing towards automation, intelligence, and high efficiency and energy saving. New technological innovations include the adoption of advanced drive systems, optimized twisting structure design, precise tension control, and intelligent monitoring systems. The application of these technologies helps to achieve a more stable and controllable twisting process, improving the production quality and efficiency of composite yarns. Composite yarn twisting processing equipment is rapidly evolving towards integration, multi-functionality, and automation to adapt to the development trends of the modern textile industry.
[0004] The preparation of sun-protective yarns typically involves adding materials with sun-protective functions, such as UV absorbers or reflectors, to the fibers. Adding UV-resistant masterbatch: During fiber preparation, sun-protective properties can be imparted to the yarn by adding UV-resistant masterbatch to the spinning solution. Nano-titanium dioxide (TiO2), due to its excellent UV shielding ability and high refractive index, can be loaded onto microspheres for the preparation of sun-protective yarns. By coating the yarn surface with materials possessing sun-protective properties, the yarn's sun-protective ability can be directly improved. Summary of the Invention

[0016] A method for preparing sunscreen yarn, using the aforementioned composite yarn twisting processing apparatus, includes the following steps:
[0017] Prepare core spools containing sun-protective yarn and winding spools for various types of winding yarn;
[0018] Inside an unwinding mechanism, the core wire spool is placed inside the core wire unwinder, and each winding spool is placed inside its respective winding unwinder.
[0019] By guiding, the core wire and each winding wire pass through the guiding mechanism and the twisting mechanism respectively, and are wound around the outside of each empty spool installed inside the spool mounting mechanism;
[0020] After the core wire and each winding wire are fed through the core wire feeder and the winding wire feeders, the core wire and each winding wire pass through the guide mechanism and are twisted inside the twisting mechanism outside the core wire.
[0021] Driven by the moving drive mechanism, the twisted yarn rotates outside each empty bobbin so that the twisted yarn is wound around the outside of each empty bobbin installed inside the bobbin mounting mechanism.
[0022] After the twisted yarn is fully wound around each empty bobbin, the twisted yarn is pulled down by the yarn clamping mechanism to provide space to cut the twisted yarn so that a new empty bobbin can be installed inside the bobbin mounting mechanism.
[0023] Remove the cut end of the twisted yarn from the yarn clamping mechanism so that the newly twisted yarn can be wound around the outside of a new empty spool.
[0024] Compared with the prior art, the present invention provides a composite yarn twisting processing device and a method for preparing sunscreen yarn, which has the following beneficial effects:
[0025] 1. This composite yarn twisting processing device uses a core yarn feeder positioned at the geometric center of several winding feeders to directly output the core yarn from the center of each winding, ensuring a constant twisting center and guaranteeing the twisting quality of the composite yarn. After the core yarn and each winding pass through the guiding mechanism, the windings are twisted outside the core yarn inside the twisting mechanism. Then, driven by the moving drive mechanism, the twisted yarn rotates outside each empty bobbin, winding the twisted yarn onto the outside of each empty bobbin installed inside the bobbin mounting mechanism, enabling continuous output of the twisted composite yarn. The yarn is twisted; after each empty bobbin is fully wound with the twisted yarn, the twisted yarn is pulled down by the clamping mechanism to provide space to cut the twisted yarn. This allows a new empty bobbin to be installed inside the bobbin mounting mechanism. The cut end of the twisted yarn is removed from the clamping mechanism so that the newly twisted yarn can be wound around the outside of the new empty bobbin. This provides sufficient space for workers to operate and also provides space for mechanical movement of the yarn cutting machine during actual use. This improves the efficiency of replacing the empty bobbin inside the bobbin mounting mechanism and effectively increases the overall efficiency of twisting composite yarn.
[0026] 2. This composite yarn twisting processing device allows adjustment of the angle between the tension adjusting rod and the positioning box by rotating the tension adjusting rod. This adjustment controls the tension of the yarn tensioned between the last winding wheel and the tension wheel, ensuring that the angles between the tension adjusting rods of each winding and unwinding device and the positioning box are equal and smaller than those of the core yarn unwinding device. This allows control over the tensile force on each yarn twisted outside the core yarn within the twisting mechanism. A tension difference is created between the core yarn at the center and the outer windings, ensuring higher tension of the core yarn relative to the outer windings. This allows for denser outer windings to be twisted outside the core yarn, effectively ensuring the outer windings cover the core yarn and resulting in superior performance in the twisted yarn.

[0038] 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.
[0039] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a composite yarn twisting processing device and a method for preparing sunscreen yarn.
[0040] Example 1:
[0041] Please refer to Figures 1-10 A composite yarn twisting processing device includes: a fixed frame 1, a wire feeder 11 at the top of the fixed frame 1, a plurality of unwinding mechanisms 2 inside the wire feeder 11, each unwinding mechanism 2 including a plurality of wire feeders 21, each wire feeder 21 inside the unwinding mechanism 1 being divided into a core wire feeder and a plurality of winding wire feeders, the core wire feeders being located at the geometric center position formed by the plurality of winding wire feeders; a support frame 12 in the middle of the fixed frame 1, a top support plate 13 at the top of the support frame 12, a moving drive mechanism 3 above the top support plate 13, a guide mechanism 4 and a twisting mechanism 5 on the side of the moving drive mechanism 3 away from the unwinding mechanism 2, the guide mechanism 4 and the twisting mechanism 5 being able to move synchronously under the drive of the moving drive mechanism 3; a bobbin mounting mechanism 6 inside the support frame 12, and a bottom end... Support plate 14, with a clamping mechanism 7 above the bottom support plate 14; according to the composition of the composite yarn, the core yarn spool is placed inside the core yarn feeder, and each winding spool is placed inside the winding feeder. Through the feeder of the core yarn feeder and each winding feeder, the core yarn and each winding pass through the guide mechanism 4. Inside the twisting mechanism 5, each winding is twisted outside the core yarn; driven by the moving drive mechanism 3, the twisted yarn output from the twisting mechanism 5 can rotate outside the empty yarn spools installed inside the winding spool mounting mechanism 6, and can be wound onto each empty yarn spool; after winding on each empty yarn spool, the clamping mechanism 7 clamps and pulls down the twisted yarn, providing space to cut the twisted yarn, and retains the yarn end of the twisted yarn so that it can continue to be wound outside a new empty yarn spool.
[0042] In use, firstly, according to the type of yarn being produced (twisted), prepare the required core spool containing the core yarn and the winding spool containing various winding yarns. Then, inside an unwinding mechanism 2, place one core spool and several winding spools respectively inside the core yarn unwinder and each winding unwinder (the number of winding unwinders is increased or decreased according to the actual production process; in this embodiment, two windings are used, meaning there are two winding unwinders inside one unwinding mechanism 2). This ensures that the core yarn is output directly from the center position of each winding spool, as the core yarn unwinder is positioned at the geometric center formed by the several winding unwinders. This guarantees a constant twisting center and ensures the twisting of the composite yarn. Quality; then, only in one twisting batch, at the beginning stage, the core yarn and each winding yarn are guided through the guide mechanism 4 and the twisting mechanism 5 respectively, and wound around the outside of each empty spool installed inside the spool mounting mechanism 6, so that the yarn is fed out by each pay-off device 21 (core yarn pay-off device and each winding pay-off device). After the core yarn and each winding yarn pass through the guide mechanism 4 respectively, each winding yarn is twisted outside the core yarn inside the twisting mechanism 5. Then, driven by the movement drive mechanism 3, the twisted yarn rotates outside each empty spool so that the twisted yarn is wound around the outside of each empty spool installed inside the spool mounting mechanism 6, so that the twisted composite yarn can be continuously output.
[0043] After the twisted yarn is wound around each empty bobbin, the twisted yarn is pulled down by the clamping mechanism 7 to provide space to cut the twisted yarn. This allows a new empty bobbin to be installed inside the bobbin mounting mechanism 6. The cut end of the twisted yarn is removed from the clamping mechanism 7 so that the newly twisted yarn can continue to be wound around the outside of the new empty bobbin. This provides sufficient space for workers to operate and also provides space for mechanical movement of the yarn cutting machine during actual use. This improves the efficiency of replacing the empty bobbin inside the bobbin mounting mechanism 6 and effectively increases the overall efficiency of twisting composite yarn.
[0044] Example 2:
[0045] Please refer to Figures 1-5 The difference from the above embodiments is that each wire feeder 21 includes a positioning box 211. One end of the positioning box 211 is provided with a wire feeder shaft 212. The end of the positioning box 211 away from the wire feeder shaft 212 is provided with a tension rod 213. The end of the tension rod 213 away from the positioning box 211 is rotatably provided with a tension wheel 214. A plurality of winding wheels 215 are provided on one side of the positioning box 211. Each wire feeder shaft 212 can temporarily fix the core wire shaft and each winding shaft according to the type of wire feeder 21. The wires released from each wire feeder shaft 212 can pass through each winding wheel 215 in sequence and finally be output to the guide mechanism 4 from the tension wheel 214.
[0046] A tension adjusting rod 216 is provided on one side of the positioning box 211. The tension adjusting rod 216 extends into the positioning box 211 and is fixed to the end of the tension rod 213 away from the tension wheel 214. By rotating the tension adjusting rod 216, the included angle between the tension adjusting rod 216 and the positioning box 211 can be adjusted, thereby adjusting the tension of the wire tensioned between the last winding wheel 215 and the tension wheel 214.
[0047] The included angles between the tension adjusting rod 216 of each winding and unwinding device and the positioning box 211 are all equal, and the included angles between the tension adjusting rod 216 of each winding and unwinding device and the positioning box 211 are all smaller than the included angles between the tension adjusting rod 216 of the core wire unwinding device and the positioning box 211.
[0048] In practical use, the core wire spool and each winding spool can be temporarily fixed to the outside of the corresponding core wire feeder and the feeder spool 212 of each winding feeder, so that the corresponding core wire and each winding can be output from the feeder spool 212. The wires released from each feeder spool 212 can pass through each winding wheel 215 in sequence and finally be output to the guide mechanism 4 from the tension wheel 214. By rotating the tension adjusting rod 216, the included angle between the tension adjusting rod 216 and the positioning box 211 can be adjusted, and the tension of the wire (including the core wire and each winding) tensioned between the last winding wheel 215 and the tension wheel 214 can be adjusted, so that the included angle between the tension adjusting rod 216 of each winding feeder and the positioning box 211 can be maintained. The tension adjustment rods 216 and positioning boxes 211 of each winding and unwinding device are equal, and the included angle between each winding and unwinding device and the positioning box 211 is smaller than the included angle between the tension adjustment rods 216 and positioning boxes 211 of the core wire unwinding device. This allows control over the tensile force on each wire that is twisted outside the core wire inside the twisting mechanism 5. This creates a tension difference between the core wire at the center and the windings on the outside, ensuring a higher tension relative to the outer windings. This allows for denser outer windings to be twisted outside the core wire, effectively ensuring the coverage of the core wire (usually a high-strength support wire) by the outer windings (generally functional wires), resulting in better performance in the twisted yarn.
[0049] Example 3:
[0050] Please refer to Figures 1-2 , Figures 6-10The difference from the above embodiment is that the guiding mechanism 4 includes a guiding plate 41, and the surface of the guiding plate 41 is provided with a plurality of guiding holes 42, the number of guiding holes 42 being consistent with the total number of unwinding devices 21; the twisting mechanism 5 includes a twisting plate 51, the top end of the twisting plate 51 is provided with a plurality of twisting tubes 52, and the bottom end of the twisting plate 51 is provided with a plurality of output guiding tubes 53, the number of twisting tubes 52 and output guiding tubes 53 being consistent with the number of unwinding mechanisms 2.
[0051] Each twisting tube 52 includes a core wire guide tube 521 and several winding guide tubes 522. The bottom ends of the core wire guide tube 521 and each winding guide tube 522 are connected to the output guide tube 53. The number of winding guide tubes 522 in each twisting tube 52 is equal to the number of winding and unwinding devices in each unwinding mechanism 2. Each winding guide tube 522 is wound around the outside of the core wire guide tube 521. Under the guidance of the winding guide tubes 522, each winding can be twisted and wound around the outside of the core wire inside the output guide tube 53, and the twisted yarn is output from the bottom end of the output guide tube 53.
[0052] Thus, through the pre-setting of the winding guide tube 522, each winding guide tube 522 is respectively wound around the outside of the core wire guide tube 521, so that each winding wire passing through each winding guide tube 522 can be twisted around the outside of the core wire passing through the core wire guide tube 521, so that the twisted yarn can be output through the bottom end of the output guide tube 53.
[0053] The moving drive mechanism 3 includes an X-axis drive motor 31 and an X-axis moving plate 32. The X-axis moving plate 32 is slidably mounted on the upper surface of the top support plate 13. The output shaft of the X-axis drive motor 31 is threadedly connected to one end of the X-axis moving plate 32, and the X-axis drive motor 31 can drive the X-axis moving plate 32 to move along the X-axis direction. A Y-axis moving plate 33 is slidably mounted on the upper surface of the X-axis moving plate 32. A Y-axis drive motor 34 is mounted on one side of the Y-axis moving plate 33, and the output shaft of the Y-axis drive motor 34 is connected to the Y-axis moving plate 33. One end of the Y-axis drive motor 34 is threadedly connected to the other end of the Y-axis drive plate 33, which can drive the Y-axis moving plate 33 to move along the Y-axis direction. The top end of the Y-axis moving plate 33 is provided with a Z-axis drive rod 35 and a Z-axis drive motor 36. The Z-axis drive motor 36 and the Z-axis drive rod 35 are connected by a power transmission. A movable mounting plate 37 is sleeved on the outside of the Z-axis drive rod 35. One side of the movable mounting plate 37 is threadedly connected to the Z-axis drive rod 35. The Z-axis drive motor 36 can drive the movable mounting plate 37 to move along the Z-axis direction through the Z-axis drive rod 35.
[0054] The guide plate 41 and the twisting plate 51 are respectively fixed at the top and bottom of the movable mounting plate 37 on the side away from the Z-axis drive rod 35; the bobbin mounting mechanism 6 includes several empty bobbin mounting rods 61, and an empty bobbin can be mounted on the outside of each empty bobbin; the guide plate 41 and the twisting plate 51 can move with the movable mounting plate 37 to wind the twisted yarn output from the bottom of the output guide tube 53 around the outside of each empty bobbin.
[0055] The wire clamping mechanism 7 includes a wire clamp fixing plate 71 and several movable wire clamps 72. Each movable wire clamp 72 is fixed to the top of the wire clamp fixing plate 71, and each movable wire clamp 72 is pneumatically controlled to open and close. The upper surface of the bottom support plate 14 is provided with a lifting drive rod 73 and a wire clamp drive motor 74. The lifting drive rod 73 is threadedly connected to one side of the wire clamp fixing plate 71, and the lifting drive rod 73 and the wire clamp drive motor 74 are connected for power transmission. The wire clamp drive motor 74 can drive the wire clamp fixing plate 71 to lift and lower each movable wire clamp 72 through the lifting drive rod 73.
[0056] After the empty spools on the outside of each empty spool mounting rod 61 are fully wound with twisted yarn, the twisted yarn is moved above the clamp fixing plate 71 by the moving drive mechanism 3, following the movement of the bottom end of the output guide tube 53. This ensures that there is a section of twisted yarn between the twisted yarn and the empty spools on the outside of each empty spool mounting rod 61. At this time, the clamp drive motor 74 can drive the clamp fixing plate 71 to lift each movable clamp 72 through the lifting drive rod 73, so as to move each open movable clamp 72 to the outside of the taut twisted yarn. The movement is controlled pneumatically. The moving clamp 72 closes, and then each moving clamp 72 descends, pulling down the twisted yarn and providing space to cut the twisted yarn. The twisted yarn can be cut between the moving clamp 72 and the empty spool mounting rod 61 (an empty spool full of twisted yarn), leaving the yarn end inside each moving clamp 72. This allows the cut yarn end to be removed from the clamping mechanism 7, so that the newly twisted yarn can continue to be wound around the outside of a new empty spool. This improves the efficiency of replacing the empty spool inside the spool mounting mechanism 6, and effectively increases the overall efficiency of twisting composite yarn.
[0057] Example 4:
[0058] A method for preparing sunscreen yarn, using a composite yarn twisting processing apparatus as described in any one of Examples 1-3, includes the following steps:
[0059] Prepare core yarn spools containing sun-protective yarn (the core yarn is a high-strength support yarn, and in this embodiment, high-strength polyester yarn can be selected) and various winding yarns (the winding yarn is a functional yarn containing sun-protective material, and in this embodiment, polyester yarn obtained by co-extrusion of anti-ultraviolet materials can be selected).
[0060] Inside an unwinding mechanism 2, the core wire spool is placed inside the core wire unwinder, and each winding spool is placed inside its respective winding unwinder.
[0061] By guiding, the core wire and each winding wire pass through the guiding mechanism 4 and the twisting mechanism 5 respectively, and are wound around the outside of each empty spool installed inside the spool mounting mechanism 6;
[0062] After the core wire and each winding wire are fed through the core wire feeder and each winding wire feeder, the core wire and each winding wire pass through the guide mechanism 4 respectively, and then each winding wire is twisted outside the core wire inside the twisting mechanism 5.
[0063] Driven by the moving drive mechanism 3, the twisted yarn rotates outside each empty bobbin so that the twisted yarn is wound around the outside of each empty bobbin installed inside the bobbin mounting mechanism 6.
[0064] After the twisted yarn is fully wound around each empty bobbin, the twisted yarn is pulled down by the yarn clamping mechanism 7 to provide space to cut the twisted yarn so that a new empty bobbin can be installed inside the bobbin mounting mechanism 6.
[0065] Remove the cut end of the twisted yarn from the clamping mechanism 7 so that the newly twisted yarn can continue to be wound around the outside of the new empty spool.
[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
