Description

Technical Field

[0001] This invention relates to the field of steel cord processing, specifically to a steel cord rewinding machine. Background Technology

[0002] In the production of steel cord, due to wire breakage or other product quality defects during the twisting process, some semi-finished steel cords that do not meet the customer's required length per meter are produced. These semi-finished steel cords are then transferred to the next rewinding process for further production. Using a rewinding machine, semi-finished steel cords of different lengths are welded together and rewound to produce finished steel cords that meet the customer's requirements.

[0003] However, in this process, semi-finished steel cord of different lengths needs to be evenly wound around the outside of the roller. Currently, existing rollers use multiple power sources to control the roller in stages during winding, meaning each action—rotation, movement, deceleration, and stopping—requires a separate power source. This design is complex, and the internal components have relatively simple functions, failing to achieve structural simplification. Furthermore, because the roller itself has inertia, simply decelerating the power source will cause the roller to continue rotating due to inertia, and the steel cord will continue to wind around one end of the roller. However, if the roller suddenly stops, the motor, acting as the power source, will also stop abruptly. The motor experiences a sudden change in resistance, and this abrupt torque change can damage the motor, affecting its lifespan.

[0004] To address this, it is necessary to design a steel cord rewinding machine. This steel cord rewinding machine has a simple structure and can achieve step-by-step deceleration of the winding rollers, thus avoiding damage to other parts of the device caused by sudden stops of the winding rollers. Summary of the Invention

[0005] Therefore, it is necessary to provide a steel cord rewinding machine to address the existing technical problems.

[0006] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows:

The power gear is keyed to the output end of the power motor. The two drive gears are symmetrically positioned on both sides of the power gear and mesh with it. The two drive shafts are keyed to the two drive gears respectively, and the two drive shafts are rotatably connected to the two support frames respectively.

[0016] Furthermore, the moving mechanism also includes a linkage shaft, a linkage support rod, a linkage rod, a fixed bracket, two drive worm gears, and two drive worm wheels. The two drive worm gears are respectively sleeved with the two drive shafts and can slide relative to each other. The two drive worm wheels are respectively meshed with the two drive worm gears. The linkage shaft is keyed to the two drive worm wheels. The linkage support rod is located beside one of the drive worm gears. One end of the linkage support rod is fixedly connected to the linkage shaft, and one end of the linkage rod is hinged to the other end of the linkage support rod. One end of the fixed bracket is hinged to the other end of the linkage rod, and the other end is fixedly connected to the support frame.

[0017] Furthermore, the moving mechanism also includes a moving platform, a moving slider, and a limiting bracket. The two ends of the limiting bracket are fixedly connected to two support frames, the moving slider is slidably connected to the limiting bracket, the two sides of the moving slider are connected to two drive worm gears, the moving slider is also slidably connected to the drive shaft, and the moving platform is fixedly connected to the upper end of the moving slider.

[0018] Furthermore, the centering mechanism includes a clamping sleeve, a clamping spring, a positioning baffle, and a support shaft seat. The clamping sleeve is slidably sleeved on the outside of the winding roller shaft. The support shaft seat is located at the end of the winding roller shaft. The upper end of the support shaft seat is rotatably connected to the winding roller shaft, and the lower end is fixedly connected to the moving platform. The positioning baffle is fixedly connected to one end of the support shaft seat near the winding roller shaft. One end of the clamping spring abuts against the clamping sleeve, and the other end abuts against the positioning baffle.

[0019] Furthermore, the first reduction assembly includes a linkage gear, a drive gear, a first pulley, a first belt, a second pulley, a first bevel gear, and a second bevel gear. The second bevel gear is coaxially and fixedly connected to the end of the winding roller shaft away from the power motor. The first bevel gear is located beside the second bevel gear and meshes with it. The second pulley is coaxially connected to the first bevel gear via a pin. The linkage gear is keyed to the end of the linkage shaft away from the linkage support rod. The drive gear is located above the linkage gear and meshes with it. The first pulley is fixedly connected to the end of the drive gear near the moving platform via a pin. One end of the first belt is drivenly connected to the first pulley, and the other end is drivenly connected to the second pulley.

[0020] Furthermore, the first deceleration assembly includes a short linkage shaft, a third bevel gear, a fourth bevel gear, a driving long shaft, a driven long shaft, and several limiting deceleration mechanisms. The short linkage shaft is keyed to the driving gear, the third bevel gear is keyed to the end of the short linkage shaft away from the driving gear, the fourth bevel gear is located beside the third bevel gear and meshes with the third bevel gear, the driving long shaft is keyed to the fourth bevel gear, the driven long shaft is located beside the driving long shaft and is parallel to the driving long shaft, and one end of each of the several limiting deceleration mechanisms is connected to the driving long shaft, and the other end is connected to the driven long shaft.

[0021] Furthermore, the limit reduction mechanism includes a third pulley, a second belt, and a fourth pulley. The third pulley is keyed to the driving long shaft, and the fourth pulley is keyed to the driven long shaft. One end of the second belt is driven to the third pulley, and the other end is driven to the fourth pulley. Several reduction grooves are formed on the outer edge of the second belt.

[0022] The beneficial effects of this invention compared to the prior art are:

[0023] Firstly, this device adopts a design that links the power motor and the winding roller shaft, allowing the winding roller shaft to react directly and affect the power motor. This enables the winding roller shaft to decelerate in advance, preventing it from continuing to rotate under inertial force after it stops. It also simplifies the device structure and avoids delayed feedback caused by the lack of linkage between the power motor and the winding roller shaft, which would affect the winding effect of the steel cord and cause negative effects such as wire slippage.

[0024] Secondly, this device uses the friction between several second belts and the steel cord to decelerate the winding roller. The steel cord is wound around the outside of the winding roller in turn, which achieves a step-by-step deceleration of the winding roller. This avoids the sudden stop of the winding roller after winding is completed, which would cause a sudden increase in the torque of the power motor and damage it. In this device, the winding roller is decelerated step by step under the action of several second belts, and the resistance force on the power motor also increases step by step, which helps to extend the service life of the power motor.

Detailed Implementation

[0035] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0036] refer to Figures 1 to 8 Steel cord rewinding machine, including:

[0037] The traction roller 2 is set in a vertical position;

[0038] Traction roller shaft 1 is keyed to traction roller 2;

[0039] The winding roller 3 is located beside and below the traction roller 1;

[0040] Two centering mechanisms 4 are symmetrically arranged outside the winding roller shaft 3;

[0041] The moving mechanism 9 is located below the winding roller shaft 3 and can drive the winding roller shaft 3 to move back and forth in the axial direction;

[0042] The first deceleration assembly 24 is connected to the moving mechanism 9 and includes a plurality of limiting deceleration mechanisms 37 evenly distributed along the axial direction of the winding roller shaft 3. The plurality of limiting deceleration mechanisms 37 can exert an increasing clamping force on the winding roller shaft 3.

[0043] Two second deceleration mechanisms 42 are respectively installed at both ends of the winding roller shaft 3. The two second deceleration mechanisms 42 can assist in decelerating the winding roller shaft 3.

[0044] During operation, the steel cord is wound around the outside of the winding roller 3 after passing through the traction roller 2. The two centering mechanisms 4 on the winding roller 3 ensure that the steel cord remains centered when it is wound on the winding roller 3. Then, the moving mechanism 9 can drive the winding roller 3 to move along the axial direction. Subsequently, the moving mechanism 9 can also drive the winding roller 3 to rotate through the first deceleration component 24, and apply friction to the steel cord outside the winding roller 3 through several limit deceleration mechanisms 37, so that the winding roller 3 gradually decelerates, realizing the step-by-step deceleration of the winding roller 3. During this process, the two second deceleration mechanisms 42 can ensure that the winding roller 3 can stop rotating, preventing the winding roller 3 from decelerating too slowly due to its own inertia.

[0045] To ensure that the winding roller 3 can eventually stop rotating and to prevent it from continuing to rotate after winding is completed, the following features are specifically designed:

[0046] The second deceleration mechanism 42 includes a power cylinder 43 and a deceleration block 44. The power cylinder 43 is vertically positioned at the end of the winding roller shaft 3. The deceleration block 44 is fixedly connected to the output end of the power cylinder 43. The moving mechanism 9 includes a power motor 23, a power gear 22, two drive gears 15, two drive shafts 14, and two support frames 11. The two support frames 11 are arranged along the axial direction of the winding roller shaft 3. The power motor 23 is fixedly connected to one of the support frames 11 through a motor frame. The power gear 22 is keyed to the output end of the power motor 23. The two drive gears 15 are symmetrically positioned on both sides of the power gear 22 and mesh with the power gear 22. The two drive shafts 14 are keyed to the two drive gears 15 respectively, and the two drive shafts 14 are rotatably connected to the two support frames 11 respectively. When the device is running: the power motor 23 starts and drives the power gear 22 to rotate. The rotation of the power gear 22 drives the two drive gears 15 meshing with it to rotate. The rotation of the two drive gears 15 drives the two drive shafts 14 connected to it to rotate. When the winding roller shaft 3 needs to be decelerated, the two power cylinders 43 start and drive the deceleration block 44 to move. After the deceleration block 44 moves, it will abut against both ends of the winding roller shaft 3, and finally stop the winding roller shaft 3 from rotating.

[0047] In order to integrate the power source and enhance the compactness of the device structure, the following features are specifically designed:

[0048] The moving mechanism 9 also includes a linkage shaft 18, a linkage support rod 19, a linkage rod 20, a fixed bracket 21, two drive worm gears 16, and two drive worm wheels 17. The two drive worm gears 16 are rotatably connected to the two drive shafts 14 and can slide relative to each other. The two drive worm wheels 17 are meshed with the two drive worm gears 16. The linkage shaft 18 is keyed to the two drive worm wheels 17. The linkage support rod 19 is located beside one of the drive worm gears 16. One end of the linkage support rod 19 is fixedly connected to the linkage shaft 18. One end of the linkage rod 20 is hinged to the other end of the linkage support rod 19. One end of the fixed bracket 21 is hinged to the other end of the linkage rod 20, and the other end is fixedly connected to the support frame 11. During operation: The rotation of the two drive shafts 14 drives the two drive worms 16 to rotate, which in turn drives the two drive worm wheels 17 meshing with them to rotate. The rotation of the two drive worm wheels 17 drives the keyed linkage shaft 18 to rotate, which in turn drives the hinged linkage support rod 19 to rotate. The rotation of the linkage support rod 19 drives the hinged linkage rod 20 to move. The other end of the linkage rod 20 is hinged to the fixed bracket 21, so the linkage rod 20 will reciprocate around the hinge point connected to the fixed bracket 21. During this process, the linkage rod 20, in conjunction with the linkage support rod 19, drives the linkage shaft 18 to reciprocate along the axis of the drive shaft 14. Finally, the linkage shaft 18 reacts to the drive worms 16, causing the two drive worms 16 to reciprocate along the axis of the drive shaft 14.

[0049] In order to enable the winding roller 3 to reciprocate in the axial direction, the following features are specifically designed:

[0050] The moving mechanism 9 also includes a moving platform 10, a moving slider 13, and a limiting bracket 12. The two ends of the limiting bracket 12 are fixedly connected to two support frames 11, respectively. The moving slider 13 is slidably connected to the limiting bracket 12. Both sides of the moving slider 13 are connected to two drive worm gears 16, respectively. The moving slider 13 is also slidably connected to the drive shaft 14. The moving platform 10 is fixedly connected to the upper end of the moving slider 13. During operation: the movement of the two drive worm gears 16 drives the moving slider 13 to reciprocate, and the movement of the moving slider 13 drives the moving platform 10 to reciprocate. During this process, the limiting bracket 12 improves the stability of the moving slider and prevents the moving slider 13 from exerting excessive pressure on the two drive shafts 14, thus avoiding deformation of the two drive shafts 14.

[0051] To ensure that the steel cord can be evenly wound around the outside of the winding roller 3, the following features are specifically designed:

[0052] The centering mechanism 4 includes a clamping sleeve 5, a clamping spring 6, a positioning baffle 7, and a support shaft seat 8. The clamping sleeve 5 is slidably sleeved on the outside of the winding roller shaft 3. The support shaft seat 8 is located at the end of the winding roller shaft 3. The upper end of the support shaft seat 8 is rotatably connected to the winding roller shaft 3, and the lower end is fixedly connected to the moving platform 10. The positioning baffle 7 is fixedly connected to the end of the support shaft seat 8 near the winding roller shaft 3. One end of the clamping spring 6 abuts against the clamping sleeve 5, and the other end abuts against the positioning baffle 7. When the device is running, in order to ensure that the steel cord is always kept in the center of the winding roller shaft 3 and does not fall off, the two clamping sleeves 5 will approach each other under the action of the clamping spring 6. As mentioned above, the reciprocating movement of the moving platform 10 will drive the two support shaft seats 8 to move, and the movement of the two support shaft seats 8 will drive the winding roller shaft 3 to move, so that the steel cord can be evenly wound on the outside of the winding roller shaft 3.

[0053] In order to drive the winding roller 3 to rotate, the following features are specifically designed:

[0054] The first reduction assembly 24 includes a linkage gear 25, a drive gear 26, a first pulley 27, a first belt 28, a second pulley 29, a first bevel gear 30, and a second bevel gear 31. The second bevel gear 31 is coaxially and fixedly connected to the end of the winding roller shaft 3 away from the power motor 23. The first bevel gear 30 is located beside the second bevel gear 31 and meshes with it. The second pulley 29 is coaxially connected to the first bevel gear 30 via a pin. The linkage gear 25 is keyed to the end of the linkage shaft 18 away from the linkage support rod 19. The drive gear 26 is located above the linkage gear 25 and meshes with it. The first pulley 27 is fixedly connected to the end of the drive gear 26 near the moving platform 10 via a pin. One end of the first belt 28 is connected to the first pulley 27, and the other end is connected to the second pulley 29. When the device is running, the rotation of the linkage shaft 18 will drive the linkage gear 25 to rotate, the linkage gear 25 will drive the drive gear 26 meshing with it to rotate, the drive gear 26 will drive the first pulley 27 connected to it to rotate, the first pulley 27 will drive the second pulley 29 to rotate via the first belt 28, the second pulley 29 will drive the first bevel gear 30 to rotate via the pin, the first bevel gear 30 will drive the second bevel gear 31 meshing with it to rotate, and the second bevel gear 31 will drive the winding roller shaft 3 connected to it to rotate.

[0055] In order to integrate the power source so that several limit reduction mechanisms 37 can be linked with the power motor 23, the following features can be specifically set:

[0056] The first deceleration assembly 24 includes a short linkage shaft 32, a third bevel gear 33, a fourth bevel gear 34, a driving long shaft 35, a driven long shaft 36, and several limiting deceleration mechanisms 37. The short linkage shaft 32 is keyed to the driving gear 26. The third bevel gear 33 is keyed to the end of the short linkage shaft 32 away from the driving gear 26. The fourth bevel gear 34 is located beside the third bevel gear 33 and meshes with it. The driving long shaft 35 is keyed to the fourth bevel gear 34. The driven long shaft 36 is located beside the driving long shaft 35 and is parallel to it. One end of each limiting deceleration mechanism 37 is connected to the driving long shaft 35, and the other end is connected to the driven long shaft 36. When the device is running: the rotation of the drive gear 26 will drive the short shaft 32 to rotate, the rotation of the short shaft 32 will drive the third bevel gear 33 connected to it to rotate, the rotation of the third bevel gear 33 will drive the fourth bevel gear 34 meshing with it to rotate, and the rotation of the fourth bevel gear 34 will drive the drive long shaft 35 connected to it to rotate. It can be seen that the direction of the fourth bevel gear 34 is opposite to the direction of the second bevel gear 31, that is, the direction of the drive long shaft 35 is opposite to the direction of the winding roller shaft 3.

[0057] In order to ensure that the deceleration process of the winding roller 3 is a gradual decrease, the following features are specifically set:

[0058] The limiting and deceleration mechanism 37 includes a third pulley 38, a second belt 39, and a fourth pulley 41. The third pulley 38 is keyed to the driving long shaft 35, and the fourth pulley 41 is keyed to the driven long shaft 36. One end of the second belt 39 is connected to the third pulley 38, and the other end is connected to the fourth pulley 41. Several deceleration grooves 40 are formed on the outer edge of the second belt 39. When the device is running: the rotation of the driving long shaft 35 will drive the several third pulleys 38 connected to it to rotate. The several third pulleys 38 will drive the several fourth pulleys 41 to rotate through the several second belts 39. It can be seen that the direction of rotation of the several second belts 39 is opposite to the direction of rotation of the winding roller shaft 3. As the thickness of the steel cord coil on the winding roller shaft 3 increases, the several second belts 39 will come into contact with the steel cord on the winding roller shaft 3. At this time, the deceleration grooves 40 on the several second belts 39 can increase the friction between the second belts 39 and the steel cord. This friction will resist the rotation of the winding roller shaft 3. When the rotation of the winding roller shaft 3 is obstructed, the torque of the power motor 23 will increase. At this time, the power cylinder 43 will start and drive the deceleration block 44 to abut against both ends of the winding roller shaft 3, thus completing the step-by-step deceleration of the winding roller shaft 3.

[0059] The working principle of this device is as follows: The steel cord is first wound around the outside of the winding roller 3 by the traction roller 2. During this process, due to errors, there will be uneven spacing between each turn of the steel cord when it is wound around the outside of the winding roller 3. At this time, the two clamping sleeves 5 will move closer to each other under the action of the two clamping springs 6. The two clamping sleeves 5 will apply force to the steel cord, causing the steel cord to move and eliminating the error distance between each turn of the steel cord. That is, the two clamping sleeves 5 will abut against the steel cord wound around the outside of the winding roller 3, ensuring that the steel cord can be evenly wound around the outside of the winding roller 3. It should be noted that the movement stroke of the winding roller 3 should match the relative position of the two clamping sleeves 5 to prevent the steel cord from passing over the two clamping sleeves 5 and being miswound around the two clamping springs 6 during the winding process.

[0060] During the winding process of the steel cord, the power motor 23 starts, and the moving platform 10 moves back and forth with the cooperation of the drive worm 16 and the drive worm wheel 17. The steel cord will be evenly wound layer by layer on the outside of the winding roller 3 during the back and forth movement of the winding roller 3. At the same time, the rotation of the second bevel tooth 31 will drive the winding roller 3 to rotate. The rotation of the winding roller 3 can provide power for the steel cord to be wound on the outside of the winding roller 3. The rotation direction of the fourth bevel tooth 34 is opposite to the rotation direction of the second bevel tooth 31. That is, when the fourth bevel tooth 34 rotates, the direction of the second belt 39 is opposite to the direction of the winding roller 3.

[0061] Ultimately, as the length of the steel cord on the winding roller 3 increases, the thickness of the steel cord coil gradually increases. The increased steel cord eventually comes into contact with the second belt 39. Since the steel cord is wound sequentially around the outside of the winding roller 3, several second belts 39 will sequentially come into contact with their corresponding steel cord coils. During this process, the resistance experienced by the winding roller 3 gradually increases. Because the winding roller 3 and the power motor 23 are directly linked via a mechanical structure, the resistance experienced by the power motor 23 also gradually increases, preventing sudden torque changes that could damage the power motor 23. Finally, when all the second belts 39 have come into contact with the steel cord, the progressively increasing resistance experienced by the power motor 23 reaches its maximum value, at which point the speed of the winding roller 3 will be greatly reduced. The two power cylinders 43 will also drive the deceleration block 44 to completely decelerate the winding roller 3, thus completing the deceleration process.

[0062] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
