Description

Technical Field

[0001] The invention relates to the technical field of composite yarn twisting, in particular to a composite yarn twisting processing device and a method for preparing sun-proof yarn. Background Art

[0002] Composite yarn twisting processing device is a key equipment for producing special performance yarn in the textile industry. Composite yarn is usually composed of two or more fibers of different properties combined by a specific processing method to achieve comprehensive properties such as the gloss and strength of filament and the softness and warmth of staple fiber. This kind of yarn is widely used in clothing, home textiles and other fields, and can meet diverse market needs. In the production process of composite yarn, twisting is an important link, which is not only related to the appearance quality of the yarn, but also directly affects the performance of the final product. Traditional twisting processing methods are often inefficient and difficult to meet the modern textile industry's pursuit of high efficiency and high quality. Therefore, the research and development of composite yarn twisting processing devices has become the key to improving production efficiency, reducing costs and improving product quality.

[0003] In recent years, with the continuous advancement of textile technology, composite yarn twisting processing devices are also developing towards automation, intelligence and high efficiency and energy saving. New technological innovations include the use 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 and improve the production quality and efficiency of composite yarns. Composite yarn twisting processing devices are rapidly evolving towards integration, multi-functions and automation to adapt to the development trend of the modern textile industry.

[0004] The preparation method of sun-protective yarn usually involves adding materials with sun-protective functions to the fiber, such as UV absorbers or reflectors. Adding anti-UV masterbatch: During the preparation of the fiber, the yarn can be given sun-protective properties by adding anti-UV masterbatch to the spinning solution. Nano titanium dioxide (TiO2) can be loaded on microspheres due to its good UV shielding ability and high refractive index for the preparation of sun-protective yarn. By coating the surface of the yarn with materials with sun-protective properties, the sun protection ability of the yarn can be directly improved. Summary of the invention

[0042] When in use, first prepare the required core wire shaft containing core wire materials and winding shaft containing various winding wire materials according to the type of yarn to be produced (twisted), and then place a core wire shaft and several winding shafts in a core wire pay-off and each winding pay-off (the number of winding pay-offs is increased or decreased according to the actual production process, and the number of windings selected in this embodiment is two, that is, the number of winding pay-offs in an unwinding mechanism 2 is two), so that the core wire pay-off is set at the geometric center position formed by several winding pay-offs, and the core wire is directly output from the center position of each winding, so as to ensure that the twisting center is constant and the twisting of the composite yarn is ensured. Quality; then only in one twisting batch, at the beginning stage, the core wire and each winding wire are guided to pass through the guiding mechanism 4 and the twisting mechanism 5 respectively, and are wound around the outside of each empty bobbin installed inside the bobbin mounting mechanism 6, so as to pass through the pay-off of each pay-off device 21 (core wire pay-off device and each winding wire pay-off device), after the core wire and each winding wire pass through the guiding mechanism 4 respectively, each winding wire is twisted outside the core wire inside the twisting mechanism 5, and then driven by the mobile driving mechanism 3, the twisted yarn is rotated 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, so as to continuously output the twisted composite yarn;

[0044] Embodiment 2:

[0045] Please refer to Figure 1-Figure 5 , the difference from the above-mentioned embodiment is that the wire unwinder 21 includes a positioning box 211, a wire unwinding shaft 212 is arranged at one end of the positioning box 211, a tension rod 213 is arranged at the end of the positioning box 211 away from the wire unwinding shaft 212, a tension wheel 214 is rotatably arranged at the end of the tension rod 213 away from the positioning box 211, and a plurality of winding wheels 215 are arranged on one side of the positioning box 211; each wire unwinding shaft 212 can temporarily fix the core wire shaft and each winding shaft according to the type of the wire unwinder 21, and the wire released from each wire unwinding shaft 212 can pass around each winding wheel 215 in turn and finally be output to the guide mechanism 4 from passing around the tension wheel 214.

[0046] A tension adjustment rod 216 is provided on one side of the positioning box 211. The tension adjustment rod 216 extends into the interior of 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 adjustment rod 216, the angle between the tension adjustment rod 216 and the positioning box 211 can be adjusted to adjust the tension of the wire tensioned between the last winding wheel 215 and the tension wheel 214.

[0047] The angles between the tension adjustment rods 216 of each wire winding and unwinding device and the positioning box 211 are equal, and the angles between the tension adjustment rods 216 of each wire winding and unwinding device and the positioning box 211 are smaller than the angles between the tension adjustment rods 216 of the core wire unwinding device and the positioning box 211.

[0048] During specific use, the core wire spool and each winding spool can be temporarily fixed on the outer side of the corresponding core wire pay-off and the pay-off shaft 212 of each winding pay-off, so that the corresponding core wire and each winding wire can be output from the pay-off shaft 212, and the wire released from each pay-off shaft 212 can be bypassed by each winding wheel 215 in turn and finally output to the guide mechanism 4 from bypassing the tension wheel 214.

[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 passing through each winding guide tube 522 can be respectively wrapped and twisted on 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 mobile driving mechanism 3 includes an X-axis driving motor 31 and an X-axis moving plate 32. The X-axis moving plate 32 is slidably arranged on the upper surface of the top support plate 13.

[0056] After the empty bobbins outside each empty-axle mounting rod 61 are fully wound with the twisted yarn, the twisted yarn is moved to the top of the wire clamp fixing plate 71 following the movement of the bottom end of the output guide tube 53 under the drive of the mobile drive mechanism 3, so that there is a section of twisted yarn between the twisted yarn and the empty wire outside each empty-axle mounting rod 61. At this time, the wire clamp driving motor 74 can drive the wire clamp fixing plate 71 to lift each mobile wire clamp 72 through the lifting driving rod 73, so as to move each open mobile wire clamp 72 to the outside of the section of taut twisted yarn, and each mobile wire clamp 72 is pneumatically controlled to move. The movable wire clamps 72 are closed, and then each movable wire clamp 72 descends to pull down the clamped twisted yarn, providing space for cutting the twisted yarn, and the twisted yarn can be cut between the movable wire clamp 72 and the empty shaft mounting rod 61 (an empty shaft wound with twisted yarn), and the thread ends are retained inside each movable wire clamp 72, so that the thread ends of the cut twisted yarn can be removed from the wire clamping mechanism 7, so that the newly twisted yarn can continue to be wound on the outside of the new empty shaft, thereby improving the efficiency of replacing a new empty shaft inside the shaft mounting mechanism 6, and can effectively increase the overall efficiency of twisting the composite yarn.
