Automatic twisting device

Abstract

The present invention discloses an automated twisting device, which relates to the technical field of textile equipment and includes a frame, a support assembly, a pay-off assembly, a wrapped wire, a core wire, and a guide wheel. The present invention provides a support assembly that can rotate around the core wire. By arranging multiple pay-off assemblies on the outside of the support assembly, the pay-off assemblies can rotate with the support assembly to achieve the winding of the wrapped wire around the core wire. The pay-off assemblies can rotate to achieve the self-rotation of the wrapped wire, thereby improving the twisting effect of the fiber product. The release position of the wrapped wire of the pay-off assembly can be adjusted. Since the wrapped wire performs a circular motion around the core wire, when the release position of the wrapped wire is adjusted, the radius of its circular motion changes. When the core wire movement speed is constant, the closer the position of the wrapped wire is to the outside, the smaller its winding density is, thereby achieving the adjustment and control of the wrapped wire winding twisting density, so that the device can perform twisting processing of fiber yarns of different specifications for nylon curtains of different specifications.

Description

Technical Field

[0001] The present invention relates to the technical field of textile equipment, in particular to an automatic yarn twisting device. Background Art

[0002] Cord fabric: A tire skeleton fabric made from strong strands of yarn as the warp and medium- and fine-count single yarns as the weft. The warp threads are closely arranged, while the weft threads are sparsely spaced, resembling a cord, hence the name. Cord fabric serves as the skeleton for tires and other rubber products, enabling them to withstand immense pressure, shock loads, and intense vibration. It is clear that cord fabric is a critical material affecting tire performance and lifespan. The warp threads (also known as cord yarns) bear the load, while the weft yarns secure the warp threads in place. Requirements for cord fabric are: ① high strength and initial modulus; ② heat resistance; ③ fatigue resistance; ④ structural stability; and ⑤ rubber adhesion. There are many different types of cord fabric. For nylon cord fabric, the primary processes are fiber production and rubber impregnation, both of which directly impact product performance. For fibers, the strength of the fibers is generally improved by twisting and winding the core wire and the covering wire. However, after twisting, the specifications of the fibers change to a certain extent. When producing curtains of different styles and thicknesses, fibers of different specifications need to be used. This requires controlling and adjusting the twisting of the fibers, mainly controlling the winding density of the covering wire on the outside of the core wire.

[0003] A textile twisting device with publication number CN112342651A includes a workbench, a mounting plate welded to the rear of the workbench, a twisting mechanism arranged inside the workbench, two support plates welded to the front of the mounting plate, a rotating shaft movably connected between the two support plates, a winding drum movably connected to the surface of the rotating shaft, and a winding mechanism arranged at the front of the mounting plate. The present invention uses the twisting mechanism and the winding mechanism to enable multiple strands of yarn to rotate while twisting, so that each strand of yarn can be twisted when it is tightly wound, which can ensure that there will be no uneven thickness after twisting, beautify the appearance, reduce the production of defective products, and can twist up to nine strands of textile yarn at the same time, increasing the scope of application of the device, and rewind the twisted yarn in a left-right reciprocating manner, thereby preventing the yarn from being entangled during winding.

[0004] The above technical solution drives the multi-strand rotation through the ageing mechanism to improve the twisting strength. However, the winding density of each wire on the outside of the core wire is constant, and it is difficult to adjust the winding density of the sheath on the outside of the core wire according to demand.

[0045] Moreover, a third reversing bevel gear 314 is fixedly arranged at one end of the support shaft 305. A fourth reversing bevel gear 315 is arranged on one side of the third reversing bevel gear 314. An extension seat 316 is arranged at the bottom end of the fourth reversing bevel gear 315 through a bearing, and the extension seat 316 is fixedly arranged at the bottom end of one side of the sliding seat 303.

[0046] Moreover, a movable bevel gear 320 is fixedly arranged at the bottom end of the hexagonal shaft 318, and the movable bevel gear 320 meshes with the fixed bevel gear 208. When the support plate 301 rotates following the rotating shaft 202, the support plate 301 drives the hexagonal shaft 318 to rotate around the rotating shaft 202, and the hexagonal shaft 318 drives the movable bevel gear 320 to rotate. At this time, the movable bevel gear 320 rotates around the fixed bevel gear 208, and at this time, the movable bevel gear 320 rotates self - rotatably. The movable bevel gear 320 drives the hexagonal shaft 318 to rotate self - rotatably, and the hexagonal shaft 318 drives the fourth reversing bevel gear 315 to rotate self - rotatably through the shaft sleeve 317. At this time, the power input to the wire pay - off assembly 3 can be realized;

[0047] Meanwhile, a threaded groove 321 is penetrated through the inner wall of the top end of the chute 302, and an adjusting screw 322 is penetrated through the inside of the threaded groove 321. The bottom end of the adjusting screw 322 is movably arranged at the middle of the top end of the sliding seat 303 through a bearing. By rotating the adjusting screw 322, the position of the sliding seat 303 can be adjusted;

[0048] Furthermore, on one side where the two rotating seats 307 are close to each other, "C" - shaped mounting frames 323 are fixedly arranged, and the mounting frames 323 correspond to the wire pay - off rollers 308. A locking bolt 324 is arranged in a screw hole penetrated through the middle of the outer side of the mounting frame 323, and one end of the locking bolt 324 is in contact with the outer side wall of the wire pay - off roller 308. The locking bolt 324 can lock both ends of the wire pay - off roller 308 to realize the installation of the wire pay - off roller 308;

[0049] The guide wheel 6 is set as a traction wheel, and the guide wheel 6 corresponds to the core wire 5. The guide wheel 6 can play a role in traction of the core wire 5 to facilitate the twisting operation.

[0050] To sum up, when this device is in use, first, the core wire 5 is passed through the support assembly 2, and the core wire 5 is guided to pass through the guide wheel 6. The guide wheel 6 traction the core wire 5, and then the covering wire 4 is guided to wind and twist on the outer side of the core wire 5. According to the production specifications of the fiber filaments, the position of the wire pay - off assembly 3 is adjusted to realize the adjustment of the winding tightness of the covering wire 4 on the outer side of the core wire 5. Then, the support assembly 2 is started, so that the support assembly 2 drives the wire pay - off assembly 3 to rotate around the core wire 5. At this time, the covering wire 4 can wind and twist on the outer side of the core wire 5, and during the twisting process, the covering wire 4 can rotate self - rotatably to ensure the twisting effect;

[0051] When performing the twisting operation, the driving motor 205 drives the transmission gear 204 to rotate through the driving gear 204, and the transmission gear 203 can drive the rotating shaft 202 to rotate. The rotating shaft 202 drives the support plate 301 to rotate, the support plate 301 drives the sliding seat 303 to rotate, and the sliding seat 303 drives the support seat 306 to rotate around the core wire 5 through the support seat 305;

[0052] When the support plate 301 rotates following the rotating shaft 202, the support plate 301 drives the hexagonal shaft 318 to rotate around the rotating shaft 202, and the hexagonal shaft 318 drives the movable bevel gear 320 to rotate. At this time, the movable bevel gear 320 rotates around the fixed bevel gear 208. At this time, the movable bevel gear 320 rotates, and the movable bevel gear 320 drives the hexagonal shaft 318 to rotate. The hexagonal shaft 318 drives the fourth reversing bevel gear 315 to rotate through the shaft sleeve 317. The fourth reversing bevel gear 315 drives the third reversing bevel gear 314 to rotate. The third reversing bevel gear 314 drives the support shaft 305 to rotate. The support shaft 305 drives the support base 306 to rotate. The support base 306 drives the pay-off roller 308 to rotate, so as to control the rotation of the wrapped wire 4 and ensure the twisting effect.

[0053] At the same time, when the support shaft 305 drives the support seat 306 to rotate, the support seat 306 drives the transmission shaft 311 to rotate. At this time, the transmission shaft 311 rotates relative to the slide seat 303, and the transmission shaft 311 drives the movable gear 312 to rotate, so that the movable gear 312 rotates around the ring gear 313. At this time, the movable gear 312 rotates on its own, and the movable gear 312 drives the second reversing bevel gear 310 to rotate through the transmission shaft 311. The second reversing bevel gear 310 drives the first reversing bevel gear 309 to rotate, and then drives the rotating seat 207 to rotate. The rotating seat 207 can drive the pay-off roller 208 to rotate to realize the release of the wrapped wire 4. At this time, the wrapped wire 4 is released to the outside of the core wire 5 and is wrapped around the core wire 5 and twisted to achieve a twisting effect.

[0054] When adjusting the winding tightness of the wrapped wire 4 on the outside of the core wire 5, by rotating the adjusting screw 322, the adjusting screw 322 cooperates with the thread groove 321, so that the slide 303 slides in the slide groove 302, and the slide 303 can drive the support seat 306 to slide through the support shaft 305, and then drive the pay-off roller 308 to slide, so as to adjust the release position of the wrapped wire 4. Since the wrapped wire 4 makes a circular motion around the core wire 5, when the movement speed of the electrocardiogram 5 and the winding speed of the wrapped wire 4 are constant, the position of the wrapped wire 4 is adjusted so that the radius of the circular motion of the wrapped wire 4 changes. At this time, the linear speed of the circular motion of the wrapped wire 4 changes. When the core wire 5 moves the same distance, the wrapped wire 4 wrapped on the outside changes. At this time, the winding tightness of the wrapped wire 4 on the outside of the core wire 5 changes.
