Description

Technical Field

[0001] This utility model relates to the technical field of metal wire processing equipment, specifically a wire take-up machine for twisting and releasing. Background Technology

[0002] As the core equipment of the metal wire processing production line, the winding machine undertakes the important task of orderly winding the wire after the front-end process. Its performance is directly related to the convenience of storage, transportation safety and availability of the finished wire products for subsequent processing.

[0003] However, existing take-up machines only have basic winding functions and lack a targeted torque elimination mechanism. When wire with residual torque enters the take-up machine, it will gradually accumulate and release during the winding process, causing problems such as kinking and spiral deformation of the wire. The kinked wire will cause uneven tension, resulting in disordered wire arrangement and interlayer compression on the I-beams. This not only affects the quality of the wound wire, but also causes wire jamming problems during subsequent unwinding.

[0004] Therefore, it is necessary to design a torsion release take-up machine that is unaffected by the torque force of the wire. Utility Model Content

[0005] The purpose of this invention is to provide a winding take-up machine for twisting and releasing, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a twist release take-up machine, including a frame, a wire feeding mechanism on one side of the frame, a wire take-up mechanism on the other side of the frame, and a straightening mechanism in the middle of the frame; The wire feeding mechanism includes a self-rotating component on which an I-beam can be mounted.

A main shaft is fixedly connected to the center of the bottom surface of the flange turntable. The output end of the first motor is connected to the main shaft through the first synchronous belt drive component, so that the first motor drives the flange turntable and the self-rotating component to revolve simultaneously.

[0007] In one embodiment of this utility model, the straightening mechanism includes a second motor, a second synchronous belt drive assembly, and a virtual twister. The virtual twister includes a twist seat with a cavity. Multiple over-twist rollers are rotatably arranged in the cavity. The twist seat has drive shafts at both ends. The drive shafts at both ends have coaxial through holes and deep groove ball bearings. The second motor is fixed inside the frame. The output end of the second motor is connected to the lower drive shaft via the second synchronous belt drive assembly.

[0008] In one embodiment of the present invention, the frame is fixedly provided with a plurality of thread guide wheels on the upper and lower sides of the virtual twister, and the frame is fixedly provided with an active traction wheel and a driven traction wheel on the side of the virtual twister near the take-up mechanism, with the active traction wheel located above the driven traction wheel.

[0009] In one embodiment of the present invention, a drive shaft is fixedly mounted on the drive traction wheel, and a reducer is connected to the other end of the drive shaft inside the frame. A third synchronous belt drive assembly is provided at the input end of the reducer. A third motor is driven and connected to the reducer through the third synchronous belt drive assembly. The third motor is fixed inside the frame. A first bearing seat is sleeved on the drive shaft, and the first bearing seat is fixedly connected to the outside of the frame.

[0010] In one embodiment of the present invention, an electromagnetic tension tuner is fixedly provided on the side of the frame near the wire feeding mechanism, a wire guide wheel is fixedly provided on the frame above the electromagnetic tension tuner, and a tension rod tuner is provided on the frame above the wire taking-up mechanism.

[0011] In one embodiment of the present invention, the frame is provided with a workbench on the take-up mechanism. The take-up mechanism includes a cable laying assembly, a mounting assembly, and a drive assembly. The cable laying assembly and the mounting assembly are both fixed on the workbench, and the drive assembly is fixed below the workbench.

[0012] In one embodiment of this utility model, the cable assembly includes a fourth motor, a lead screw, a ball bearing seat, and a support frame. The two ends of the lead screw are mounted on the two side support frames. The output end of the fourth motor is connected to one end of the lead screw via a coupling, and the fourth motor is fixed on one side support frame. The ball bearing seat is threaded onto the lead screw, and a connecting frame is fixed on the ball bearing seat. A cable-laying wheel is rotatably mounted on the connecting frame. Photoelectric sensors are provided on the two side support frames above the lead screw, and detection blocks are provided on the ball bearing seat.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are: (1) By setting up a wire feeding mechanism and a straightening mechanism, the self-rotating component of the wire feeding mechanism drives the I-beam wheel to rotate, and the first motor in the revolution component drives the flange turntable and the self-rotating component to revolve through the first synchronous belt transmission component. The combined motion of the two eliminates the initial torque of the wire in advance. The virtual twister of the straightening mechanism, driven by the second motor, ensures the stable rotation of the twist seat with a deep groove ball bearing. The over-twisting wheel in the concave cavity twists and straightens the wire, completely eliminating residual torque, avoiding kinking and spiral deformation during winding, ensuring the straightness of the wire after winding, and effectively solving the problem that the existing winding machine cannot eliminate the torque of the wire before winding. (2) By setting the mounting component in the take-up mechanism, the cylinder on the right bracket in the mounting component drives the driven dial to move axially. The distance between the active dial and the driven dial can be flexibly adjusted according to the length specification of the I-beam. The I-beam specification can be switched without replacing the entire mounting component, which greatly shortens the equipment downtime for adjustment and improves production efficiency. Secondly, the setting of the nylon pad can also avoid damage to the I-beam during clamping and ensure clamping stability. Attached Figure Description

[0016] To enable those skilled in the art to better understand the present invention, the solutions in 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 should fall within the protection scope of the present invention.

[0017] This utility model provides a technical solution: a torsion release take-up machine, including a frame 10, a wire feeding mechanism 20 on one side of the frame 10, the wire feeding mechanism 20 including a self-rotating component 21 on which a bobbin can be installed, a revolution component 22 for driving the self-rotating component 21 to rotate fixedly at the bottom of the self-rotating component 21, the revolution component 22 including a flange turntable 221, a first motor 222 and a first synchronous belt drive component 223, the self-rotating component 21 is mounted on the flange turntable 221, a main shaft 224 is fixedly connected to the center of the bottom surface of the flange turntable 221, and the output end of the first motor 222... The first motor 222 drives the flange turntable 221 and the self-rotation component 21 to revolve simultaneously through the first synchronous belt drive assembly 223 to drive the main shaft 224 and the flange turntable 221 to revolve synchronously as the wire is released. The self-rotation component 21 drives the I-beam to rotate synchronously as the wire is released. The first motor 222 in the revolving component 22 drives the main shaft 224 and the flange turntable 221 to rotate through the precise transmission of the first synchronous belt drive assembly 223, which in turn drives the I-beam on the self-rotation component 21 mounted on the flange turntable 221 to revolve as a whole. The two work together to actively dissipate the initial torque force inside the wire.

[0018] On the other side of the frame 10, a take-up mechanism 30 is provided. A worktable 15 is provided on the take-up mechanism 30. The take-up mechanism 30 includes a cable routing assembly 31, a mounting assembly 32, and a drive assembly 33. The cable routing assembly 31 and the mounting assembly 32 are both fixed on the worktable 15, and the drive assembly 33 is fixed below the worktable 15. The cable routing assembly 31 includes a fourth motor 311, a lead screw 312, a ball bearing seat 313, and a support frame 314. The two ends of the lead screw 312 are located on the two side support frames 314. The output end of the fourth motor 311 is connected to one end of the lead screw 312 via a coupling. The fourth motor 311 is fixedly mounted on a support frame 314 on one side. A ball bearing seat 313 is threaded onto the lead screw 312, and a connecting frame 315 is fixedly mounted on the ball bearing seat 313. A cable guide wheel 316 rotatably mounts on the connecting frame 315. Photoelectric sensors 317 are mounted on both support frames 314 above the lead screw 312, and detection blocks 318 are mounted on the ball bearing seat 313. The two support frames 314 provide stable support for the lead screw 312. 311 transmits power smoothly to the lead screw 312 via a coupling, driving the lead screw 312 to rotate at a constant speed. This, in turn, drives the threaded ball bearing seat 313 to reciprocate linearly along the axis of the lead screw 312. The connecting bracket 315 on the ball bearing seat 313 drives the wire guide wheel 316 to move synchronously. When the wire passes around the wire guide wheel 316, it moves with the guide wheel 316 and is evenly distributed on the I-beam. At the same time, the photoelectric sensor 317 and the detection block 318 form a precise limiting engagement. When the detection block 318 moves with the roller... When the ball seat 313 moves to the position of the photoelectric sensor 317, the photoelectric sensor 317 sends a signal to the system, and the system controls the fourth motor 311 to reverse, realizing the automatic reversal of the ball seat 313. The limit positions of the photoelectric sensors 317 on both sides can be adjusted by the slider and the adjusting rod to adapt to the I-beams of different diameters. The wire laying stroke control can be completed without manual intervention, which not only improves the wire laying efficiency, but also ensures the consistency of the reversal position, making the wires on the I-beams neat and orderly, and the layers tightly and evenly spaced.

[0019] The mounting assembly 32 includes a left bracket 321 and a right bracket 322. The drive assembly 33 includes a fifth motor 331 and a fourth synchronous belt drive assembly 332. A second bearing seat 323 is fixed on the left bracket 321. A rotating shaft 324 is fitted inside the second bearing seat 323. One end of the rotating shaft 324 is connected to the output end of the fifth motor 331 through the fourth synchronous belt drive assembly 332. An electromagnetic brake 325 is provided on the rotating shaft 324. An active dial 326 is fixed on the other end of the rotating shaft 324. A cylinder 327 is flange-connected to the right bracket 322. A driven dial 328 is rotatably connected to the piston end of the cylinder 327. The active dial 326 and the driven dial 328 are coaxially arranged and both are provided with nylon pads 329. The left bracket 321 and the right bracket 322 form a symmetrical support structure. The cylinder 327 on the right bracket 322 can be adjusted according to the length of the H-beam pulley. The flexible telescopic design allows the driven dial 328 to move axially closer to or further away from the drive dial 326, thereby adjusting the distance between the two dials and accommodating various lengths of I-beams. This solves the problem of poor adaptability in traditional fixed clamping structures and significantly shortens the I-beam replacement time. The rotating shaft 324 is stably supported by the second bearing seat 323, ensuring concentricity during rotation. The fifth motor 331 smoothly transmits power to the rotating shaft 324 through the fourth synchronous belt transmission assembly 332, driving the drive dial 326 and the clamped I-beams to rotate at a uniform speed, ensuring stable winding speed. The electromagnetic brake 325 can quickly brake the rotating shaft 324 when stopping or changing rolls, preventing the I-beams from continuing to rotate due to inertia and causing the wire to loosen. In addition, the nylon pads 329 on the drive dial 326 and the driven dial 328 can prevent surface damage caused by direct contact between the metal dials and the I-beams.

[0020] The frame 10 has a straightening mechanism 40 in the middle. The straightening mechanism 40 includes a second motor 41, a second synchronous belt drive assembly 42, and a virtual twister 43. The virtual twister 43 includes a twist seat 431 with a cavity 432. Multiple over-twist rollers 433 are rotatably arranged in the cavity 432. The twist seat 431 has drive shafts 434 at both ends. The drive shafts 434 at both ends have coaxial through holes 435 and deep groove ball bearings 436. The second motor 41 is fixed inside the frame 10. The output end of the second motor 41 is connected to the lower drive shaft 434 through the second synchronous belt drive assembly 42. The second motor 41 transmits power stably to the lower drive shaft 434 through the second synchronous belt drive assembly 42. The deep groove ball bearing 436 mounted on the drive shaft 434 effectively reduces the radial offset during rotation, enabling the twist seat 431 to rotate stably with high concentricity, providing a uniform twisting foundation for the over-twisting wheel 433. The multiple over-twisting wheels 433 in the cavity 432 form a multi-directional and uniform twisting force on the wire passing through the coaxial through hole 435, correcting the bending deformation of the wire caused by uneven stress, and effectively solving the problem of wire twisting and non-straightness after winding caused by the lack of effective straightening means in traditional winding machines.

[0021] The frame 10 has multiple guide rollers 11 fixed on the upper and lower sides of the twister 43. A drive traction roller 12 and a driven traction roller 13 are fixed on the side of the twister 43 near the take-up mechanism 30. The drive traction roller 12 is positioned above the driven traction roller 13. A drive shaft 121 is fixed on the drive traction roller 12. The other end of the drive shaft 121 extends into the frame 10 and is connected to a reducer 122. A third synchronous belt drive assembly 123 is provided at the input end of the reducer 122. The reducer 122 is connected to a third motor 124 via the third synchronous belt drive assembly 123. The third motor 124 is fixed inside the frame 10. A first bearing seat 125 is sleeved on the drive shaft 121 and is fixedly connected to... Outside the frame 10, multiple guide rollers 11 on the upper and lower sides of the virtual twister 43 form a continuous guide channel, which can accurately limit the wire entering and exiting the virtual twister 43, ensuring that the wire always moves along the axis of the wire hole 435 of the virtual twister 43, avoiding uneven twisting force during straightening due to wire deviation. The active traction roller 12 and the driven traction roller 13 cooperate to form a stable traction force on the wire. The third motor 124 serves as a power source, and transmits power to the reducer 122 through the third synchronous belt transmission assembly 123. The reducer 122 can adjust the output speed according to the wire specifications and winding requirements, and then drive the active traction roller 12 to rotate at a uniform speed through the active shaft 121, so as to achieve precise control of the wire conveying speed.

[0022] An electromagnetic tension tuner 50 is fixedly installed on the side of the frame 10 near the wire feeding mechanism 20. A wire feed guide roller 14 is fixedly installed above the electromagnetic tension tuner 50 on the frame 10. A tension rod tuner 60 is installed above the take-up mechanism 20 on the frame 10. The wire first passes through the electromagnetic tension tuner 50, which can adjust the tension of the wire in real time during the wire feeding stage to stabilize the wire tension within a preset range. After the tension is adjusted, the wire enters the wire feed guide roller 14 above, ensuring that the wire enters the straightening mechanism 40 in a stable posture. The tension rod tuner 60 above the take-up mechanism 30 can adjust the tension of the wire in real time during the take-up stage to avoid the problem of the wire being disordered due to uneven tension during winding.

[0023] Working principle: First, according to the specifications of the I-beam, the distance between the active dial 326 and the driven dial 328 is adjusted by the cylinder 327 to complete the clamping, and the photoelectric sensor 317 is adjusted to limit and adapt to the diameter of the I-beam. After starting, the first motor 222 in the wire feeding mechanism 30 drives the flange turntable 221 to drive the self-rotating component 21 and the I-beam to revolve. At the same time, the self-rotating component 21 drives the I-beam to rotate. The combined motion eliminates the initial torque of the wire. After the tension of the wire is stabilized by the electromagnetic tension tuner 50, the wire enters the wire guide wheel 14 and is guided to the straightening mechanism 40. Guided by the upper guide wheel 11, the wire enters the twisting seat 431 through the wire hole 435. The second motor 41 drives the twisting seat 431 to rotate stably. The wire passes through multiple twisting wheels 433 in sequence to straighten and eliminate residual stress. Then, the wire is guided by the lower guide wheel 11 to the active traction wheel 12 and the driven traction wheel 13. The third motor 124 drives the active traction wheel 12 to rotate at a constant speed through the speed adjustment of the reducer 122, thereby pulling the wire at a constant speed. Finally, the wire enters the take-up mechanism 30. The fifth motor 331 drives the I-beam wheel to rotate and rewind the wire. The fourth motor 311 drives the wire-laying wheel 316 to reciprocate and lay the wire. The detection block 318 and the photoelectric sensor 317 work together to achieve automatic reversal. The tension bar tuner 60 stabilizes the tension in real time. When the machine stops, the electromagnetic brake 325 brakes to prevent the wire from loosening and completes the twist release take-up.
