Description

Technical Field

[0001] This utility model relates to the technical field of metal wire processing equipment, specifically a tensioning and unloading device for the production of tin-plated copper-clad steel wire. Background Technology

[0002] A tin-coated copper-clad steel wire pay-off device is an auxiliary device for tin-coated copper-clad steel wire that is used in conjunction with a stranding machine to pay off the wire. Tin-coated copper-clad steel wire pay-off devices can be divided into powered pay-off machines and passive pay-off machines. Powered pay-off machines include gantry-type powered pay-off, box-type powered pay-off, frame-type powered pay-off, end-shaft pay-off, and gantry pay-off.

[0003] In the prior art, such as in publication number CN221191030U, a wire feeding device for producing tin-plated copper-clad steel wire is disclosed. It includes a base plate with a groove on its top. Inside the groove is a moving component for changing the direction of the tin-plated copper-clad steel wire. Above the moving component is a rotating component for feeding and recovering the metal wire. By rotating a turntable, the turntable drives a crossbar to rotate, which in turn drives a driving bevel gear to rotate. The driving bevel gear drives a driven bevel gear meshing with it to rotate, which in turn drives a first threaded rod to rotate, thereby moving a slider. The slider then moves a moving plate, and with the cooperation of an auxiliary plate, moves a first rotating roller. Adjusting the position of the first rotating roller changes the height difference between the first and second rotating rollers, thus changing the tension of the tin-plated copper-clad steel wire. This ensures the wire remains taut during feeding and recovery, preventing wire breakage.

[0004] Based on the above-mentioned existing technology, the existing tensioning and unwinding devices for tin-plated copper-clad steel wire production still have the following problems: In the initial stage of unwinding the copper-clad steel wire on the unwinding roller, there is a large amount of copper-clad steel wire on the unwinding roller, and the moment of inertia is large. It is easy for the unwinding speed to be too fast, resulting in insufficient tension of the copper-clad steel wire, which leads to loosening and tangling of the copper-clad steel wire. In the later stage of unwinding, there is a small amount of copper-clad steel wire remaining on the unwinding roller, and the moment of inertia is small. It is easy for the unwinding speed to be too slow, resulting in excessive tension of the copper-clad steel wire, which can easily lead to breakage of the copper-clad steel wire. Therefore, this utility model provides a tensioning and unwinding device for tin-plated copper-clad steel wire production. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tensioning and unwinding device for the production of tin-plated copper-clad steel wire. This device solves the problems of insufficient tension and slack in the copper-clad steel wire during the initial unwinding stage on the unwinding rollers, where a large amount of wire on the rollers results in high rotational inertia and excessively fast unwinding speed, leading to tangling and loosening of the wire. Conversely, in the later stages of unwinding, a smaller amount of wire remains on the rollers, resulting in low rotational inertia and excessively slow unwinding speed, which can cause the wire to break.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tensioning and unloading device for producing tin-plated copper-clad steel wire, comprising an unloading mechanism, a tension adaptive adjustment mechanism downstream of the unloading mechanism, and a wire drawing mechanism downstream of the tension adaptive adjustment mechanism; the tension adaptive adjustment mechanism includes a mounting frame, a U-shaped plate is mounted on the top of the mounting frame near the edge, pressure sensors are mounted on the inner bottom surface and the inner bottom surface of the U-shaped plate, two guide rods are mounted on the top of the mounting frame near the middle, a lifting block is slidably disposed between the surfaces of the two guide rods, a spring is mounted on the bottom surface of the lifting block, and the bottom end of the spring is fixedly connected to the top surface of the mounting frame, which can generate an upward thrust on the lifting block, an L-shaped connecting plate is mounted on the surface of the lifting block facing the U-shaped plate, a contact plate is connected to the bottom of the L-shaped connecting plate, the contact plate is placed inside the U-shaped plate, and the contact plate can contact any one of the pressure sensors.

[0007] Preferably, the wire feeding mechanism includes a fixed base, a motor is mounted on the outer surface of the fixed base, the output shaft of the motor movably passes through the outer surface of the fixed base and extends to the other side, and a wire feeding roller is mounted on the output shaft of the motor.

[0008] Preferably, an L-shaped fixing plate is mounted on the surface of the mounting bracket facing the wire feeding mechanism, and a wire ring is mounted on the surface of the L-shaped fixing plate.

[0009] Preferably, the front surface of the lifting block is provided with an adaptive wire roller, and the front surface of the mounting frame is provided with a lower guide roller symmetrically rotated, forming a wire feeding channel between the bottom of the two lower guide rollers and the top of the adaptive wire roller.

[0010] Preferably, the wire-drawing mechanism includes a base, a vertical plate mounted on the top of the base, a fixed frame mounted on the top of the base at the rear side of the vertical plate, an electric push rod mounted on the top surface of the fixed frame, and the telescopic end of the electric push rod slidingly through the top surface of the fixed frame and extending downwards. A lifting frame is mounted on the telescopic end of the electric push rod, and the lifting frame is located above the vertical plate. The wire-drawing mechanism also includes two wire-pressing strips, one of which is located on the front side of the vertical plate and the other is located on the inner side of the lifting frame. Each wire-pressing strip has a set of synchronous pulleys inside, which can drive the wire-pressing strip to rotate. There are two pulleys in each set. One set of synchronous pulleys is rotatably mounted on the front surface of the vertical plate, and the other set of synchronous pulleys is rotatably mounted on the inner wall of the lifting frame. Each of the two wire-pressing strips has a pressure plate inside. One pressure plate is fixed on the front surface of the vertical plate, and the other pressure plate is fixed on the inner wall of the lifting frame. The two pressure plates are in contact with the inner walls of the two wire-pressing strips on the side closest to each other.

[0011] Preferably, a controller is installed on the top of the fixed base, and the controller is electrically connected to the motor, pressure sensor and electric actuator.

[0012] Beneficial effects

[0013] This utility model provides a tensioning and unloading device for the production of tin-plated copper-clad steel wire. Compared with the prior art, it has the following advantages:

[0014] (1) In the production of tin-plated copper-clad steel wire, when the tension of the copper-clad steel wire increases or decreases during the wire feeding process, the contact plate will contact the pressure sensor above or below the U-shaped plate under the action of the spring. The pressure sensor detects the pressure change and transmits the data to the controller. The controller judges whether the tension is too large or too small based on the pressure data, and then reduces or increases the speed of the motor, so that the wire feeding speed of the feeding roller is slowed down or increased, thereby realizing the adaptive adjustment of the tension of the copper-clad steel wire and keeping it within a suitable range.

[0015] (2) The tensioning and releasing device for the production of tin-plated copper-clad steel wire, through the two pressure plates on the inner side of the pressure strip, enables the two pressure strips to approach each other without deformation, thereby increasing the friction between the two pressure strips and the tin-plated copper-clad steel wire, thus ensuring that the tin-plated copper-clad steel wire can be stably pulled out with the rotation of the pressure strip during the pulling process, without slippage or displacement.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides two technical solutions:

[0024] Figures 1-5 The first embodiment is shown: a tensioning and unloading device for producing tin-plated copper-clad steel wire, including a unloading mechanism 1, a tension adaptive adjustment mechanism 2 downstream of the unloading mechanism 1, and a wire pulling mechanism 3 downstream of the tension adaptive adjustment mechanism 2; the tension adaptive adjustment mechanism 2 includes a mounting frame 21, a U-shaped plate 25 is mounted on the top of the mounting frame 21 near the edge, pressure sensors 26 are mounted on the inner bottom surface and the inner bottom surface of the U-shaped plate 25, two guide rods 27 are mounted on the top of the mounting frame 21 near the middle, a lifting block 28 is slidably disposed between the surfaces of the two guide rods 27, a spring 210 is mounted on the bottom surface of the lifting block 28, and the bottom end of the spring 210 is fixedly connected to the top surface of the mounting frame 21, which can generate an upward thrust on the lifting block 28, and the lifting block 28 is mounted on the surface facing the U-shaped plate 25. An L-shaped connecting plate 29 is provided, with a contact plate 291 connected to its bottom. The contact plate 291 is placed inside a U-shaped plate 25 and can contact any pressure sensor 26. The wire feeding mechanism 1 includes a fixed base 11, with a motor 12 mounted on its outer surface. The output shaft of the motor 12 extends through the outer surface of the fixed base 11 and reaches the other side. A wire feeding roller 13 is mounted on the output shaft of the motor 12. An L-shaped fixed plate 22 is mounted on the surface of the mounting frame 21 facing the wire feeding mechanism 1, and a wire guide ring 23 is mounted on the surface of the L-shaped fixed plate 22. An adaptive wire roller 211 is rotatably provided on the front surface of the lifting block 28, and lower wire guide rollers 24 are symmetrically rotatably provided on the front surface of the mounting frame 21. A wire feeding channel is formed between the bottom of the two lower wire guide rollers 24 and the top of the adaptive wire roller 211.

[0025] Specifically, the motor 12 drives the feed roller 13 to rotate under the control of the controller 4, so that the tin-plated copper-clad steel wire is released from the feed roller 13. As the feeding process proceeds, when the amount of copper-clad steel wire on the feed roller 13 changes, causing a change in tension, the adaptive roller 211 will move up and down due to the change in force. If the tension decreases, the spring 210 pushes the lifting block 28 to rise, which in turn drives the adaptive roller 211 to rise. At the same time, the contact plate 291 at the bottom of the L-shaped connecting plate 29 will contact the pressure sensor 26 above. The pressure sensor 26 detects the pressure change and transmits the data to the controller 4. The controller 4 determines that the tension is too low based on the pressure data and reduces the speed of the motor 12, which slows down the feeding speed of the feed roller 13, thereby increasing the tension of the copper-clad steel wire. Conversely, if the tension increases, the copper-clad steel wire will pull the adaptive roller 211 down, and the contact plate 291 will contact the pressure sensor 26 below. The pressure sensor 26 transmits a signal to the controller 4, and the controller 4 increases the speed of the motor 12, speeds up the feeding speed, and reduces the tension.

[0026] Figures 1-5 The second embodiment is shown, and its main difference from the first embodiment is that the wire-drawing mechanism 3 includes a base 31, a vertical plate 32 is mounted on the top of the base 31, a fixing frame 33 is mounted on the top of the base 31 at the rear side of the vertical plate 32, an electric push rod 34 is mounted on the top surface of the fixing frame 33, and the telescopic end of the electric push rod 34 slides through the top surface of the fixing frame 33 and extends downward. A lifting frame 35 is mounted on the telescopic end of the electric push rod 34, and the lifting frame 35 is located above the vertical plate 32. The wire-drawing mechanism 3 also includes two wire-pressing strips 36, one of which is located on the front side of the vertical plate 32, and the other is located inside the lifting frame 35. Each wire-pressing strip 36... Each of the 6 has a set of two synchronous pulleys 37 that can drive the pressure belt 36 to rotate. One set of synchronous pulleys 37 is rotatably mounted on the front surface of the upright plate 32, and the other set of synchronous pulleys 37 is rotatably mounted on the inner wall of the lifting frame 35. Each of the two pressure belts 36 has a pressure plate 38 inside. One pressure plate 38 is fixed on the front surface of the upright plate 32, and the other pressure plate 38 is fixed on the inner wall of the lifting frame 35. The two pressure plates 38 are respectively in contact with the inner wall of the two pressure belts 36 on the side that are close to each other. The top of the fixed base 11 is equipped with a controller 4, and the controller 4 is electrically connected to the motor 12, the pressure sensor 26 and the electric push rod 34.

[0027] Specifically, the synchronous wheel 37 in the wire drawing mechanism 3 is driven by an external motor, which drives the two wire pressing belts 36 to rotate in opposite directions to pull the tin-plated copper-clad steel wire. The two pressure plates 38 on the inner side of the wire pressing belts 36 prevent deformation when the two wire pressing belts 36 come close to each other, thereby increasing the friction between the two wire pressing belts 36 and the tin-plated copper-clad steel wire. This ensures that the tin-plated copper-clad steel wire can be stably pulled out as the wire pressing belts 36 rotate during the pulling process, without slippage or displacement.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] In use, the tin-plated copper-clad steel wire is placed on the wire feeding roller 13. The released copper-clad steel wire enters the tension adaptive adjustment mechanism 2 and the wire drawing mechanism 3 in sequence through the guide ring 23. In the tension adaptive adjustment mechanism 2, the copper-clad steel wire bypasses the wire feeding channel formed by the adaptive wire roller 211 and the lower guide roller 24. In the wire drawing mechanism 3, the copper-clad steel wire passes between the two pressure strips 36. The electric push rod 34 adjusts the height of the lifting frame 35 under the control of the controller 4, thereby changing the gap between the two pressure strips 36 and clamping the copper-clad steel wire.

[0030] Subsequently, under the control of the controller 4, the motor 12 drives the pay-off roller 13 to rotate, allowing the tin-plated copper-clad steel wire to be released from the pay-off roller 13. As the pay-off process proceeds, when the amount of copper-clad steel wire on the pay-off roller 13 changes, causing a change in tension, the adaptive roller 211 will move up and down due to the change in force. If the tension decreases, the spring 210 pushes the lifting block 28 to rise, causing the adaptive roller 211 to rise. At the same time, the contact plate 291 at the bottom of the L-shaped connecting plate 29 will contact the pressure sensor 26 above. The pressure sensor 26 detects the pressure change and transmits the data to the pressure sensor 26. Controller 4 determines that the tension is too low based on the pressure data. It then reduces the speed of motor 12, slowing down the feeding speed of the feeding roller 13, thereby increasing the tension of the copper-clad steel wire. Conversely, if the tension increases, the copper-clad steel wire will pull the adaptive roller 211 downward, and the contact plate 291 will contact the pressure sensor 26 below. The pressure sensor 26 transmits a signal to controller 4, which then increases the speed of motor 12, speeds up the feeding speed, and reduces the tension. In this way, the tension of the copper-clad steel wire is adaptively adjusted to keep it within a suitable range.

[0031] The synchronous wheel 37 in the wire drawing mechanism 3 is driven by an external motor, which drives the two wire pressing belts 36 to rotate in opposite directions to pull the tin-plated copper-clad steel wire. The two pressure plates 38 on the inner side of the wire pressing belts 36 prevent deformation when the two wire pressing belts 36 come close to each other, thereby increasing the friction between the two wire pressing belts 36 and the tin-plated copper-clad steel wire. This ensures that the tin-plated copper-clad steel wire can be stably pulled out as the wire pressing belts 36 rotate during the pulling process, without slippage or displacement.
