[0002] The wire doubling machine is a machine that uses some mechanical equipment to combine two or more single wires into one strand, or to combine two or more strands into one composite strand. By doubling, silk threads of a certain thickness can be obtained.

[0003] However, traditional winding machines usually rotate and wind multiple yarns at the same time to winding, and use a tension adjustment device to adjust the tightness of the yarns during winding. However, no central yarn is set to guide the multiple yarns during the rotating winding process, which can easily cause winding deviation during yarn winding. After the yarn winding is completed, the yarn needs to be cut manually. However, the cut yarn is easy to fall off the lead-in mechanism, and the yarn needs to be led when replacing the winding drum, which not only has high labor costs but also low efficiency.

DETAILED DESCRIPTION

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0033] As described in the background technology, during conventional yarn doubling, multiple yarns are not provided with a center yarn for guiding during the rotating doubling process, which may easily affect the doubling deviation during the yarn doubling, and after the yarn doubling is completed, the yarn needs to be cut manually. However, the cut yarn is easy to fall off from the lead-in mechanism, and the yarn needs to be led when the winding drum is replaced, which not only has high labor costs but also has low efficiency. For this reason, the present embodiment provides a doubling device, which can divide the yarn into a main line and a secondary line, so that the main line is used as the doubling center line, and the secondary line is wound and doubling under the guidance of the main line, so as to reduce the deviation during the yarn doubling, and reciprocate winding is performed after the yarn tension is adjusted. After the winding is completed, the yarn can be clamped and cut to prevent the yarn from falling off after manual cutting.

[0034] See also Figure 1 - Figure 7 This embodiment proposes a wire-winding device, including a main board 1, on the upper surface of which a wire-winding mechanism 2, a tension adjustment mechanism 3 and a winding mechanism 4 are arranged in sequence from left to right, as well as a guide component located between the tension adjustment mechanism 3 and the winding mechanism 4.

[0035] refer to Figures 1 to 7 The setting of the guide component can facilitate the guidance of the yarn after it is doubling, so that the yarn can be guided from a high place into the winding mechanism 4, and the stability and stress points of the yarn during transmission are improved.

[0036] The guide assembly comprises a fixing plate 5 fixed on the upper surface of the main board 1 , and a plurality of guide rollers 6 rotatably matched with the front face of the fixing plate 5 .

[0037] By providing the guide assembly, it is possible to facilitate the guidance of the yarn after the yarn is doubling, so that the yarn after the yarn is doubling can be guided by the guide roller 6 and transferred to the winding mechanism 4 for winding.

[0038] In addition, the guide roller 6 can rotate at the fixed plate 5 to avoid wear during the yarn guiding process, and the size of the guide roller 6 is adapted to the reciprocating motion of the subsequent guide assembly to avoid yarn breaking during the reciprocating guiding process.

[0039] The wire-docking mechanism 2 includes a fixing frame 201 fixed on the upper surface of the main board 1, and a gear ring 202 rotatably connected to the inner wall of the fixing frame 201. The wire-docking mechanism 2 also includes a secondary line guide ring 203 located on the upper part of the main board 1 and arranged opposite to the gear ring 202. The wire-docking mechanism 2 also includes a plurality of secondary line rollers 204 rotatably connected to the outer surface of the gear ring 202, and a secondary line hole 205 opened on the outer surface of the secondary line guide ring 203 and opposite to the secondary line rollers 204.

[0040] refer to Figures 1 to 7 The setting of the toothed ring 202 and the central through groove between the fixed frame 201, the toothed ring 202 and the secondary line guide ring 203 can facilitate the passage of the main yarn line, so that the secondary line can pass through the secondary line hole 205 and surround the outer ring of the main line, so that the secondary line can be wound around the main line.

[0041] The wire-winding mechanism 2 also includes a connecting rod 206 fixed on the outer surface of the gear ring 202 and fixedly connected to the secondary line guide ring 203. The wire-winding mechanism 2 also includes a first servo motor 207 installed on the upper surface of the main board 1, and a first gear 208 fixedly connected to the output end of the first servo motor 207 and meshing with the gear ring 202.

[0042] By setting the connecting rod 206, it is convenient to stably connect the gear ring 202 and the secondary line guide ring 203, so that the gear ring 202 can simultaneously drive the secondary line guide ring 203 to rotate when rotating, so that the secondary line roller installed on the secondary line roller 204 can pass through the secondary line hole 205 and wrap around the main line passing through the central axis of the gear ring 202.

[0043] In addition, the main line serving as a guide for the secondary line does not rotate with the secondary line. When the wire is being wound, the first servo motor 207 is started first. The output shaft of the first servo motor 207 drives the first gear 208 to engage with the gear ring 202, so that the gear ring 202 drives the secondary line on the secondary line roller 204 and the secondary line guide ring 203 to rotate, so that the secondary line can be wound around the main line for winding.

[0044] The wire-winding mechanism 2 also includes a main wire frame 209 fixed on the upper surface of the main board 1, and a main wire roller 2010 rotatably connected to the inner wall of the main wire frame 209. The main wire roller 2010 is arranged at the same level as the central axis of the fixed frame 201 and the gear ring 202. The through hole on the outer surface of the secondary wire guide ring 203 is fixedly connected to a conical cylinder 2011 that passes through to limit the main wire.

[0045] By setting the main line roller 2010, it is convenient to locate the main line roller at the center position of the gear ring 202, so that the main line passes through the gear ring 202 and the secondary line guide ring 203 in sequence and is guided to the outside of the secondary line guide ring 203 through the limiting of the conical cylinder 2011, so that the main line is located at the center position between the secondary lines to guide the secondary lines.

[0046] As a supplement, the main line can facilitate the guidance and winding of the secondary line. Through the subsequent tension adjustment component, the main line and the secondary line can be wound during the rotation process, which can greatly improve the stability of the yarn winding process and reduce the misalignment and deviation during the winding process.

[0047] The tension adjustment mechanism 3 includes a tension adjustment frame 301 fixed on the upper surface of the main board 1, and two limiting rollers 302 fixed on the inner wall of the tension adjustment frame 301. The tension adjustment mechanism 3 also includes a tension adjustment component connected to the tension adjustment frame 301, and a compression adjustment component; the tension adjustment component is used to adjust the tightness of the yarn when it is doubling.

[0048] refer to Figures 1 to 4 The setting of the tension adjustment component requires that the yarn maintains appropriate tension when it is doubling. If the tension is too large, the yarn is prone to breakage, and if the tension is too small, the yarn is prone to relaxation, so the tension adjustment component is required to adjust the yarn tension.

[0049] The tension adjustment assembly includes a first electric push rod 303 installed on the upper surface of the tension adjustment frame 301. The output end of the first electric push rod 303 slides through the upper surface of the tension adjustment frame 301 and is fixedly connected to an adjustment roller 304. The adjustment roller 304 is used to adjust the tightness of the yarn when it is twisted.

[0050] By setting up the tension adjustment component, it is possible to facilitate the squeezing of the yarn during the winding process through the adjusting roller 304, so that the yarn is limited and blocked by the adjusting roller 304 and the limiting roller 302, and the tightness of the yarn during the winding process can be adjusted to avoid the risk of misalignment and breakage of the yarn due to the yarn being too loose or too tight during the winding process.

[0051] As a supplement, when the tension of the yarn is adjusted, by starting the first electric push rod 303, the output end of the first electric push rod 303 pushes the adjusting roller 304 to rise and fall, so that the adjusting roller 304 can squeeze the yarn, thereby adjusting the tightness of the yarn during the winding.

[0052] The clamping adjustment component includes two groups of guide grooves 305 opened on the outer surface of the tension adjustment frame 301, and a clamping roller 306 slidingly matched with the guide grooves 305. The clamping adjustment component also includes a connecting plate 307 rotatably matched with the outer ends of the two groups of clamping rollers 306, and a rack 3010 fixed to the bottom surface of the connecting plate 307. The clamping adjustment component also includes a dual-output shaft motor 308 embedded in the tension adjustment frame 301, and the two output shafts of the dual-output shaft motor 308 are fixedly connected to a second gear 309 meshing with the rack 3010 on the same side.

[0053] By providing a compression adjustment component, the tension adjustment component can be improved in adjusting the tightness of the yarn when doubling the yarn, and the main line and the secondary line can be doubling in the compression adjustment component.

[0054] As a supplement, when the yarn is doubling, by starting the dual output shaft motor 308, the two output shafts of the dual output shaft motor 308 drive the second gear 309 to mesh with the rack 3010 for transmission, so that the rack 3010 drives the pressure roller 306 to stably rise and fall under the limiting action of the guide groove 305 through the connecting plate 307, so that the distance between the pressure roller 306 and the limiting roller 302 can be adjusted, and then the pressure roller 306 can provide a certain stability in the process of yarn doubling. The winding mechanism 4 includes a winding assembly and a guide assembly, as well as a cutting assembly connected to the guide assembly. The winding assembly is used for winding the yarn after it is doubling, the guide assembly is used for reciprocating winding of the yarn after it is doubling, and the cutting assembly is used for cutting the yarn after winding is completed.

[0055] refer to Figures 1 to 7 The setting of the winding mechanism 4 can facilitate the stable winding of the yarn, and through the mutual cooperation of the winding component, the guide component and the cutting component, the yarn can be clamped and cut after being wound up with transverse reciprocating guidance, thereby avoiding the situation where the yarn becomes loose or falls off due to manual cutting of the yarn.

[0056] The winding assembly includes two first fixed blocks 401 fixed on the upper surface of the main board 1, and a winding roller 404 rotatably cooperated with the first fixed blocks 401. The winding assembly also includes an L-shaped connecting plate 402 fixed on the outer surface of the L-shaped connecting plate 402, and a second servo motor 403 installed on the inner wall of the L-shaped connecting plate 402. The output shaft of the second servo motor 403 rotates through the first fixed block 401 on the same side and is fixedly connected to the winding roller 404.

[0057] By setting up a winding assembly, it is possible to facilitate the winding of the yarn after winding, thereby improving the practicality of the overall device, and can drive the subsequent guide assembly to perform reciprocating motion, so that the yarn after winding can be reciprocated on the winding roller 404, so as to avoid stacking and misalignment during the yarn winding process.

[0058] As a supplement, when winding the yarn after winding, first wrap the front end of the yarn after winding around the winding roller 404, then start the second servo motor 403, and the output shaft of the second servo motor 403 drives the winding roller 404 to rotate, so that the winding roller 404 can wind up the yarn.

[0059] The guide assembly includes two second fixed blocks 405 fixed on the upper surface of the main board 1, and a reciprocating screw 406 rotatably matched with the second fixed blocks 405. The guide assembly also includes a threaded frame 407 threadedly matched with the reciprocating screw 406, and a sliding rod 408 sliding through the threaded frame 407 and connected to the two second fixed blocks 405. The outer surface of the sliding rod 408 is provided with a guide wheel 409 located inside the threaded frame 407.

[0060] By setting up a guide component, the setting of the threaded frame 407 and the guide wheel 409 in the guide component, it is possible to facilitate the guidance of the yarn after the yarn is doubling, and the reciprocating screw rod 406 can be driven to rotate during the rotation of the winding component, so that the reciprocating screw rod 406 drives the threaded frame 407 to continue to rotate back and forth, thereby driving the yarn to reciprocate as it is wound.

[0061] In addition, during the yarn winding process, when the second servo motor 403 rotates, it can drive the reciprocating screw rod 406 to rotate through subsequent components, so that the reciprocating screw rod 406 can cooperate with the threaded frame 407, so that the threaded frame 407 can move back and forth laterally under the limiting action of the slide rod 408, so that the yarn on the guide wheel 409 can be reciprocated and wound around the winding roller 404, avoiding stacking and misalignment during the single-position winding of the yarn.

[0062] The outer end of the reciprocating screw rod 406 rotates through the second fixed block 405 on the same side and is fixedly connected to the driven sprocket 4014. The outer surface of the output shaft of the second servo motor 403 is fixedly connected to the driving sprocket 4015, and the driving sprocket 4015 is transmission-connected to the driven sprocket 4014 through a chain.

[0063] By setting the driven sprocket 4014 and the driving sprocket 4015, the second servo motor 403 can drive the guide assembly to rotate synchronously when driving the winding roller 404 to wind the yarn, so that the guide assembly can guide the yarn laterally reciprocatingly, thereby facilitating stable winding of the yarn.

[0064] As a supplement, when the output shaft of the second servo motor 403 rotates, it can drive the driven sprocket 4014 to rotate through the active sprocket 4015 and the chain, so that the driven sprocket 4014 drives the reciprocating screw rod 406 to rotate, and then can drive the guide assembly to guide and reel the yarn.

[0065] The cutting assembly includes a second electric push rod 4010 fixedly connected to the protrusion on the outer surface of the threaded frame 407, and a cutting block 4011 fixed on the outer surface of the threaded frame 407 and located directly below the second electric push rod 4010. The output end of the second electric push rod 4010 is fixedly connected to a rubber pad 4012, and a cutting knife 4013 is installed on the outer surface of the rubber pad 4012.

[0066] By setting up the cutting component, the cutting component can move synchronously with the guide component, so that when the winding component completes winding and needs to replace the winding roller 404, the yarn can be clamped and cut, so that the cut yarn will not fall off, thereby reducing manpower loss and improving work efficiency when replacing the winding roller 404 for subsequent yarn winding.

[0067] As a supplement, when the cutting component cuts the yarn, it first starts the second electric push rod 4010, and the output end of the second electric push rod 4010 pushes the rubber pad 4012 to squeeze the yarn, so that the rubber pad 4012 can undergo elastic deformation during the squeezing process of the yarn, thereby enabling the rubber pad 4012 to stably clamp the yarn, and the continuous elastic squeezing can make the cutting knife 4013 contact with the yarn, so that the cutting knife 4013 can cut the yarn.

[0068] Working principle: When winding the yarns, first take out one roll from the multiple yarn rollers and install it on the main line roller 2010 as the main line, and the remaining yarn rollers are installed on the secondary line roller 204 as secondary lines. Then the main line is passed through the gear ring 202, the secondary line guide ring 203 and the conical cylinder 2011 in turn, and the secondary line is passed through the secondary line hole 205 to be combined with the main line to facilitate the subsequent winding work.

[0069] The combined yarn is passed through the secondary line guide ring 203, and the dual-output shaft motor 308 is started. The two output shafts of the dual-output shaft motor 308 drive the second gear 309 to mesh with the rack 3010 for transmission, so that the rack 3010 pulls the connecting plate 307 and the clamping roller 306 to descend under the limiting action of the guide groove 305, clamps the combined yarn stably, and guides and transmits the combined yarn through the limiting guides of several guide rollers 6 in turn, and passes through the cutting area of ​​the cutting assembly through the limiting guide of the guide wheel 409 to connect with the winding roller 404, thereby completing the preparation work before the yarn is doubled.

[0070] When winding the yarn, start the L-shaped connecting plate 402 and the first servo motor 207, and the output shaft of the L-shaped connecting plate 402 drives the winding roller 404 to wind the yarn, and at the same time, the active sprocket 4015 and the chain drive the driven sprocket 4014 and the reciprocating screw rod 406 to rotate, so that the reciprocating screw rod 406 drives the threaded frame 407 and the yarn to reciprocate, so that the yarn can be reciprocated on the winding roller 404. When the L-shaped connecting plate 402 is started, the first servo motor 207 can be started at the same time, and the output shaft of the first servo motor 207 drives the first gear 208 to mesh with the gear ring 202 for transmission, so that the gear ring 202 drives the secondary line roller 204 and the secondary line guide ring 203 to rotate, so as to drive the secondary line to wind the main line and wire it, so as to complete the stable winding of the yarn.

[0071] However, the yarn after the front end assembly has not been paralleled. It is only necessary to close the L-shaped connecting plate 402 and the first servo motor 207 and start the second electric push rod 4010 when the yarn after the paralleling moves into the cutting assembly, so that the second electric push rod 4010 pushes the rubber pad 4012 to squeeze the yarn after the paralleling. Continuous squeezing can make the rubber pad 4012 elastically deformed and the cutting knife 4013 can cut the yarn that has not been paralleled at the front end, so as to facilitate the connection of the yarn after the paralleling with the winding roller 404. When the winding roller 404 needs to be replaced after the winding of the yarn is completed, it is only necessary to repeat the above-mentioned cutting assembly to cut the yarn.
