Description

Technical Field

[0001] The invention relates to the technical field of electric wire production, in particular to a tension dynamic compensation device for enameled wire production. Background Art

[0002] With the rapid development of society, the power industry has also seen rapid progress, resulting in an increasing number of applications for electrical wiring. Enameled wire is a type of electrical wire. Enameled wire is a bare copper wire coated with an insulating varnish and is widely used in motors, transformers, electronic equipment, and other fields. Dynamic tension compensation in enameled wire production is a crucial step in ensuring wire quality. Dynamic tension compensation primarily uses sensors to monitor tension changes during the production process. When the sensors detect tension fluctuations, the system automatically adjusts the speed of the pulling and pay-off devices to achieve dynamic tension balance.

[0003] At present, the traditional enameled wire production uses a consistent tension, which makes it inconvenient to monitor the tension in real time. As a result, the increase and decrease of the tension makes it inconvenient to adjust the wire pay-off speed in time, and it is impossible to compensate for the wire pay-off state, which leads to damage to the wire and affects the normal production of the enameled wire. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A wire-paying mechanism, which is used to pay out the wire and control the pay-out speed, and is installed on the top of the notch plate;

[0010] In which, the pay-off mechanism includes a pay-off wheel and a rectangular frame, the pay-off wheel is installed on the top of the notch plate, the rectangular frame is fixedly installed on the top of the frame through supporting legs, a first slider is slidably installed inside the rectangular frame, a second slider is slidably installed on the inner cavity of the rectangular frame and on the side away from the first slider, a first slide bar is fixedly connected to the center of the first slider, a second slide bar is fixedly connected to the center of the second slider, a first semicircular piece is fixedly connected to the bottom of the second slider, a second semicircular piece is fixedly connected to the bottom of the first slider, and a driving assembly is installed on one end of the first slide bar and the second slide bar extending to the outside of the rectangular frame.

[0011] Preferably, the tension sensor is electrically connected to the controller, the support arm is installed at an angle, and the bending rod passes through the center of the cylinder.

[0012] Preferably, the rectangular frame and the pay-off wheel are installed at the same height, and the pay-off wheel and the top of the notch plate are detachably rolled.

[0013] Preferably, the first slide bar, the second slide bar and the rectangular frame are slidably installed, and the first slide bar and the second slide bar are installed at the same height, and the material of the first semicircular piece and the material of the second semicircular piece are both rubber.

[0014] Preferably, the driving assembly includes a semicircular groove and a servo motor, the semicircular groove is opened on the surface of the first slide bar and the surface of the second slide bar and extends to one end outside the rectangular frame, the servo motor is fixedly mounted on the supporting leg at the bottom of the rectangular frame, and the servo motor is electrically connected to the controller, the output end of the servo motor is fixedly connected to the rotating wheel, and the outer circular surface of the rotating wheel is fixedly mounted with a ball head toggle tooth. When the tension on the wire increases, the output end of the servo motor is used to drive the rotating wheel to rotate clockwise, and the ball head toggle tooth rotates together with the rotating wheel, and is combined with the rotating wheel and the semicircular groove to engage with each other, so that the first slide bar and the second slide bar are subjected to driving force, which can drive the first slider and the second slider to slide together, so that the two first semicircular pieces and the second semicircular pieces move outward, so that the first semicircular piece and the second semicircular piece can be kept away from the wire, and the friction force on the wire is reduced, thereby accelerating the moving speed of the wire and increasing the wire pay-off speed.

[0015] Preferably, the rotating wheel is installed between the first slide bar and the second slide bar, and the ball head toggle tooth and the semicircular groove are installed at the same height. When the tension on the wire is reduced, the rotating wheel is driven to rotate counterclockwise by the output end of the servo motor, and under the drive of the ball head toggle tooth, the first slide bar and the second slide bar slide in opposite directions, and under the sliding connection between the first slider and the second slider, the two first semicircular pieces and the second semicircular pieces move inward toward each other, so that the wire can be flexibly clamped by the two first semicircular pieces and the second semicircular pieces, increasing the friction between the first semicircular piece and the second semicircular piece and the wire, reducing the moving speed of the wire, thereby reducing the wire pay-off speed, and dynamically compensating for the tension.

[0016] Preferably, an opening and closing mechanism is installed at the side of the surface of the notch plate, and the opening and closing mechanism includes a supporting round rod and a cylinder, the supporting round rod is fixedly installed with the side of the surface of the notch plate by screws, the cylinder is rotatably installed at the side of the frame surface, the outer circular surface of the supporting round rod is hinged with a right-angle plate, the telescopic end of the cylinder is hinged to the bottom of the right-angle plate, and a semicircular top moving part is rotatably installed on the top of the right-angle plate, and the telescopic end of the cylinder is used to apply a pushing force to the right-angle plate, and under the support of the supporting round rod, the right-angle plate drives the semicircular top moving part to rotate clockwise to adjust the angle, and the semicircular top moving part can be used to press against the end of the pay-off wheel to limit and support the pay-off wheel, so that the pay-off wheel rotates smoothly and can pay out the line evenly, and the interaction between the structures is used to connect the structures together.

[0017] Preferably, the cylinder is installed directly below the right-angle plate, and the cylinder is installed at an angle. When the wire on the pay-off wheel is paid out, the telescopic end of the cylinder applies a pulling force to the right-angle plate, so that the right-angle plate drives the semi-circular top moving part to rotate counterclockwise to adjust the angle, thereby disengaging the semi-circular top moving part from the end of the pay-off wheel, making it easy to remove the pay-off wheel. By driving the semi-circular top moving part to different states through the right-angle plate, multiple functions can be realized.

[0018] The top end of the guide roller is fixedly provided with a circle, and the bottom end of the guide roller passes through the bottom of the inner cavity of the wire drum and extends to the outside of the wire drum. The bottom end of the limit roller is fixedly provided with a round table, and the surface of the ladder frame is fixedly connected to the elastic strip, and the outer circumferential surface of the round table is provided with a brake card interface, which limits the wire by the limit roller, so that the wire always moves from the center line of the wire drum and is not easy to deviate or skew in the arc. As the wire moves, the limit roller can be driven to rotate, so that the wire moves smoothly, and after the wire passes through the tail of the wire drum, it is convenient for the wire to be output to the bottom under the guiding action of the guide roller.

[0019] Preferably, there are two guide rollers, and the two guide rollers are symmetrically installed along the axis in the middle of the bobbin, the brake card interface is evenly distributed on the outer cylindrical surface of the table, and the end of the elastic strip away from the trapezoidal frame is in contact with the outer cylindrical surface of the table. The elastic force of the elastic strip itself is used to make the end of the elastic strip fit with the outer cylindrical surface of the table. When the guide roller is subjected to the force of the moving wire and the guide roller drives the table to rotate in the opposite direction, the end of the elastic strip is immediately inserted into the inside of the brake card interface, so that the guide roller can be braked, making it difficult for the wire to move in the opposite direction, so that the wire can only move in the discharge direction, and the wire is not easy to be disordered.

[0020] The present invention provides a dynamic tension compensation device for enameled wire production, which has the following beneficial effects:

[0021] 1. The dynamic tension compensation device for enameled wire production uses a conductor passing through the bottom of the cylinder and around the groove in the middle of the top of the support roller, making the conductor present a curved shape. It can then pass through the support of the support roller and, when the elastic ring is not supported by the elastic force, the conductor is tensioned. Since both the support roller and the cylinder can roll, rolling friction can be used to reduce the frictional resistance to the conductor, making the conductor move smoothly and less likely to get stuck.

[0022] 2. The dynamic tension compensation device for enameled wire production supports the support roller with the support arm, so that the support roller is tensioned, and through the elastic force of the elastic ring itself, when the support roller is subjected to changes in the tension of the wire, the support arm will adjust the angle, so that the elastic ring can be stretched and pressed, causing the elastic ring to deform, so that the force can be detected in real time through the tension sensor, and the tension can be collected through the tension sensor, and the collected information can be transmitted to the controller.

[0023] 3. The tension dynamic compensation device for enameled wire production, when the tension on the wire increases, uses the output end of the servo motor to drive the wheel to rotate clockwise, and the ball head toggle gear rotates together with the wheel, and combined with the meshing connection between the wheel and the semicircular groove, the first slider and the second slider are driven by a driving force, which can drive the first slider and the second slider to slide together, so that the two first semicircular pieces and the second semicircular pieces move outward, so that the first semicircular piece and the second semicircular piece can be moved away from the wire, reducing the friction force on the wire, thereby accelerating the movement speed of the wire and increasing the wire pay-off speed.

[0024] 4. The tension dynamic compensation device for enameled wire production, when the tension on the wire is reduced, drives the wheel to rotate counterclockwise through the output end of the servo motor, and under the drive of the ball head toggle tooth, makes the first slider and the second slider slide in opposite directions, and under the sliding connection between the first slider and the second slider, makes the two first semicircular pieces and the second semicircular pieces move inward toward each other, so that the wire can be flexibly clamped by the two first semicircular pieces and the second semicircular pieces, increasing the friction between the first semicircular pieces and the second semicircular pieces and the wire, reducing the moving speed of the wire, thereby reducing the wire pay-off speed, and thus achieving dynamic compensation for the tension.

[0025] 5. The dynamic tension compensation device for enameled wire production uses the telescopic end of the cylinder to apply a pushing force to the right-angle plate, and with the support of the supporting round rod, the right-angle plate drives the semi-circular top moving part to rotate clockwise to adjust the angle. The semi-circular top moving part can be used to press against the end of the pay-off wheel to limit and support the pay-off wheel, so that the pay-off wheel rotates smoothly and can pay out the wire evenly. The interaction between the structures is used to connect the structures together.

[0026] 6. The dynamic tension compensation device for enameled wire production uses the telescopic end of the cylinder to contract, which can apply pulling force to the right-angle plate, so that the right-angle plate drives the semi-dome moving part to rotate counterclockwise to adjust the angle, thereby separating the semi-dome moving part from the end of the pay-off wheel, making it easier to remove the pay-off wheel. By driving the semi-dome moving part to different states through the right-angle plate, multiple functions can be realized.

[0027] 7. The tension dynamic compensation device for the enameled wire production limits the conductor through the limiting roller, so that the conductor always moves from the center line of the wire drum, and is not easy to deflect and skew in the arc. As the conductor moves, the limiting roller can be driven to rotate, so that the conductor moves smoothly. After the conductor passes through the tail of the wire drum, it is guided by the guide roller to facilitate the output of the conductor to the bottom.

[0028] 8. The dynamic tension compensation device for enameled wire production is designed such that when the guide roller is subjected to the force of the moving conductor and the guide roller drives the round table to rotate in the opposite direction, the end of the elastic strip is immediately inserted into the interior of the brake card interface, thereby braking the guide roller and preventing the conductor from moving in the opposite direction. The conductor can only move in the discharge direction and is less likely to become misaligned. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] The first embodiment, as Figures 1 to 7 As shown, the present invention provides a technical solution:

[0042] A tension dynamic compensation device for enameled wire production, comprising:

[0043] A rack 1 and a controller 2 mounted on the top of the inner cavity of the rack 1. The two ends of the top of the rack 1 are fixedly connected with a notch plate 3 and an opening plate 4 in sequence;

[0044] A support mechanism 5 is used to provide tension to the wire and detect the tension. The support mechanism 5 is installed in the middle of the surface of the opening plate 4;

[0045] The support mechanism 5 includes a support arm 51 and an elastic ring 52. The bottom end of the support arm 51 is hinged to the side of the surface of the opening plate 4. The elastic ring 52 is fixedly connected between the support arm 51 and the opening plate 4. A tension sensor 53 is installed in the middle of the elastic ring 52. A support roller 54 is rotatably installed on the top of the support arm 51. A bending rod 55 is fixedly connected to the middle of the surface of the support arm 51. A cylinder 56 is rotatably installed in the middle of the surface of the bending rod 55. The wire passes through the bottom of the cylinder 56 and bypasses the groove in the middle of the top of the support roller 54, so that the wire presents a curved shape and can pass through the support of the support roller 54. When the elastic ring 52 does not support the elastic force, the wire is tensioned and stretched. It can roll through the support roller 54 and the cylinder 56, so that rolling friction can be used to reduce the friction resistance to the wire.

[0046] The tension sensor 53 is electrically connected to the controller 2 , the support arm 51 is installed at an angle, and the bending rod 55 passes through the center of the cylinder 56 .

[0047] As the support arm 51 supports the support roller 54, the support roller 54 is tensioned, and the elastic force of the elastic ring 52 itself causes the support roller 54 to be affected by the change of the wire tension force. The support arm 51 will adjust the angle, and can stretch and press the elastic ring 52, so that the elastic ring 52 is deformed. The tension sensor 53 is installed in the middle of the elastic ring 52, so that the tension sensor 53 can detect the acting force in real time, and the tension can be collected by the tension sensor 53, and the collected information can be transmitted to the controller 2.

[0048] The pay-off mechanism 6 is used to pay the wire and control the pay-off speed. The pay-off mechanism 6 is installed on the top of the notched plate 3;

[0049] Among them, the pay-off mechanism 6 includes a pay-off wheel 61 and a rectangular frame 62, the pay-off wheel 61 is installed on the top of the notched plate 3, the rectangular frame 62 is fixedly installed on the top of the frame 1 through supporting legs, the inside of the rectangular frame 62 is slidably installed with a first slider 63, and the inner cavity of the rectangular frame 62 and the side away from the first slider 63 is slidably installed with a second slider 64, the center of the first slider 63 is fixedly connected to a first slide 65, the center of the second slider 64 is fixedly connected to a second slide 66, the bottom of the second slider 64 is fixedly connected to a first semicircular piece 67, the bottom of the first slider 63 is fixedly connected to a second semicircular piece 68, and the first slide 65 and the second slide 66 extend to one end outside the rectangular frame 62 and are installed with a drive assembly 69.

[0050] The rectangular frame 62 and the pay-off wheel 61 are installed at the same height, and the pay-off wheel 61 and the top of the notched plate 3 are detachably and rollably mounted.

[0051] The first slide bar 65 and the second slide bar 66 are slidably installed between the rectangular frame 62 and are installed at the same height. The first semicircular piece 67 and the second semicircular piece 68 are both made of rubber.

[0052] The driving assembly 69 includes a semicircular groove 691 and a servo motor 692. The semicircular groove 691 is opened on the surface of the first slide 65 and the surface of the second slide 66 and extends to one end outside the rectangular frame 62. The servo motor 692 is fixedly installed at the support leg at the bottom of the rectangular frame 62, and the servo motor 692 is electrically connected to the controller 2. The output end of the servo motor 692 is fixedly connected to the rotating wheel 693, and the outer surface of the rotating wheel 693 is fixedly installed with a ball head toggle tooth 694. When the tension on the wire increases, the tension sensor 53 transmits the information of the tension increase collected to the controller 2. The controller 2 processes the information and controls the servo motor through the controller 2. The servo motor 692 can be turned on by controlling the machine 692. The rotation of the output end of the servo motor 692 can drive the rotating wheel 693 to rotate clockwise, and the ball head toggle tooth 694 rotates together with the rotating wheel 693, and the rotating wheel 693 is engaged with the semicircular groove 691, so that the first slide bar 65 and the second slide bar 66 are driven by the driving force, which can drive the first slider 63 and the second slider 64 to slide together, so that the two first semicircular pieces 67 and the second semicircular pieces 68 move outward, so that the first semicircular piece 67 and the second semicircular piece 68 can be kept away from the wire, and the friction force on the wire is reduced, thereby speeding up the moving speed of the wire and increasing the wire-releasing speed.

[0053] The rotating wheel 693 is installed between the first slide bar 65 and the second slide bar 66, and the ball head toggle tooth 694 and the semicircular groove 691 are installed at the same height. When the tension on the wire is reduced, the controller 2 processes the information of the tension reduction and controls the servo motor 692 again. By rotating the output end of the servo motor 692 in the opposite direction, the rotating wheel 693 can be driven by the output end of the servo motor 692 to rotate counterclockwise, and under the drive of the ball head toggle tooth 694, the first slide bar 65 and the second slide bar 66 slide in opposite directions, and under the sliding connection of the first slider 63 and the second slider 64, the two first semicircular pieces 67 and the second semicircular pieces 68 move inward toward each other, and the wire can be flexibly clamped by the two first semicircular pieces 67 and the second semicircular pieces 68, thereby increasing the friction between the first semicircular piece 67 and the second semicircular piece 68 and the wire, so that the moving speed of the wire is reduced, thereby reducing the wire pay-off speed.

[0054] The second embodiment, based on the first embodiment, see Figures 1 to 8 As shown:

[0055] When the locking cam 73 is in the unlocking state, the locking cam 73 is in the unlocking state, and the locking cam 73 is in the unlocking state, so that the locking cam 73 can be unlocked easily, and the winch cam 73 can be unlocked easily.

[0056] The cylinder 72 is installed just below the right-angle plate 73. The cylinder 72 is installed at an angle. When the wire on the pay-off wheel 61 is finished, the cylinder 72 can be opened again to work. The telescopic end of the cylinder 72 contracts, and a pulling force can be applied to the right-angle plate 73, so that the right-angle plate 73 drives the semicircular moving part 74 to rotate counterclockwise to adjust the angle, thereby disengaging the semicircular moving part 74 from the end of the pay-off wheel 61, making it easier to remove the pay-off wheel 61.

[0057] The third embodiment, based on the first and second embodiments, see Figures 1 to 10 As shown:

[0058] An auxiliary mechanism 8 is installed in the middle of the top of the frame 1. The auxiliary mechanism 8 includes a bracket 81. A guide roller 82 is installed on the top of the bracket 81. A ladder frame 83 is fixedly connected to the middle of the surface of the bracket 81. The top of the ladder frame 83 is fixedly connected to the threading drum 84. The inner cavity of the drum 84 is rotatably installed with a limiting roller 85. The bottom end of the limiting roller 85 passes through the bottom of the inner cavity of the drum 84 and extends to the outside. A round table 86 is fixedly installed on the bottom of the limiting roller 85. The surface of the ladder frame 83 is fixedly connected to The elastic strip 87 and the outer circumference of the truncated cone 86 are provided with a brake card interface 88. By passing the wire between the two symmetrical limiting rollers 85, the wire can be limited by the limiting rollers 85, so that the wire always moves from the center line of the wire drum 84, and is not easy to deviate or skew in the arc. As the wire moves, the limiting rollers 85 can be driven to rotate, so that the wire moves smoothly. After the wire passes through the tail of the wire drum 84, it is guided by the guide roller 82 to facilitate the wire to be output to the bottom.

[0059] There are two guide rollers 82, and the two guide rollers 82 are symmetrically installed along the axis in the middle of the bobbin 84. The brake card interface 88 is evenly distributed on the outer cylindrical surface of the truncated cone 86. The end of the elastic strip 87 away from the ladder frame 83 is in contact with the outer cylindrical surface of the truncated cone 86. The elastic force of the elastic strip 87 itself is used to make the end of the elastic strip 87 fit the outer cylindrical surface of the truncated cone 86. When the guide roller 82 is subjected to the force of the moving wire and the guide roller 82 drives the truncated cone 86 to rotate in the opposite direction, the end of the elastic strip 87 is immediately inserted into the inside of the brake card interface 88, which can brake the guide roller 82, making it difficult for the wire to move in the opposite direction, so that the wire can only move in the discharge direction, and the wire is not easy to be disordered.

[0060] When in use, first install the pay-off wheel 61 with the wire wound on it on the top of the notched plate 3, and the staff starts the cylinder 72 to work. By extending the telescopic end of the cylinder 72, a pushing force can be applied to the right-angle plate 73. Under the support of the supporting round rod 71, the right-angle plate 73 drives the semicircular moving piece 74 to rotate clockwise to adjust the angle. The semicircular moving piece 74 can be pressed against the end of the pay-off wheel 61 to limit and support the pay-off wheel 61.

[0061] One end of the wire on the pay-off wheel 61 passes between the first semicircular piece 67 and the second semicircular piece 68 at the bottom of the rectangular frame 62, extends to the inside of the wire drum 84, and passes between two symmetrical limit rollers 85. The wire passes through the center of the wire drum 84 and bypasses the top of the guide roller 82. The wire passes through the bottom of the cylinder 56 and bypasses the groove body in the middle of the top of the support roller 54, so that the wire presents a curved shape and can pass through the support roller 54. Under the condition that the elastic ring 52 does not support the elastic force, the wire is tensioned and stretched. It can roll through the support roller 54 and the cylinder 56, so that rolling friction can be used to reduce the friction resistance to the wire.

[0062] As the support arm 51 supports the support roller 54, the support roller 54 is tensioned, and the elastic force of the elastic ring 52 itself causes the support roller 54 to be subjected to the change of the wire tension force. The support arm 51 adjusts its angle, thereby stretching and pressing the elastic ring 52, causing the elastic ring 52 to deform. The tension sensor 53 is installed in the middle of the elastic ring 52, so that the tension sensor 53 can detect the acting force in real time, and the tension sensor 53 can collect the tension and transmit the collected information to the controller 2.

[0063] When the tension on the wire increases, the tension sensor 53 transmits the collected information of the tension increase to the controller 2, and the controller 2 processes the information and controls the servo motor 692 through the controller 2, so that the servo motor 692 can be turned on. The rotation of the output end of the servo motor 692 can drive the rotating wheel 693 to rotate clockwise, and the ball head toggle gear 694 rotates together with the rotating wheel 693, and is engaged with the semicircular groove 691 in combination with the rotating wheel 693, so that the first slide bar 65 and the second slide bar 66 are driven by the driving force, which can drive the first slider 63 and the second slider 64 to slide together, so that the two first semicircular pieces 67 and the second semicircular pieces 68 move outward, so that the first semicircular piece 67 and the second semicircular piece 68 can be moved away from the wire, and the friction force on the wire is reduced, thereby speeding up the moving speed of the wire and increasing the wire-releasing speed.

[0064] At the same time, when the tension on the wire is reduced, the controller 2 processes the information of the tension reduction and controls the servo motor 692 again. By the output end of the servo motor 692 rotating in the opposite direction, the rotating wheel 693 can be driven by the output end of the servo motor 692 to rotate counterclockwise, and driven by the ball head toggle tooth 694, the first slide bar 65 and the second slide bar 66 slide in opposite directions, and under the sliding connection of the first slider 63 and the second slider 64, the two first semicircular pieces 67 and the second semicircular pieces 68 move inwardly toward each other, and the two first semicircular pieces 67 and the second semicircular pieces 68 can flexibly clamp the wire, increase the friction between the first semicircular piece 67 and the second semicircular piece 68 and the wire, reduce the moving speed of the wire, and thus reduce the wire pay-off speed;

[0065] The elastic force of the elastic strip 87 is utilized to make the end of the elastic strip 87 fit with the outer circumference of the round table 86. When the guide roller 82 is subjected to the force of the moving wire and the guide roller 82 drives the round table 86 to rotate in the opposite direction, the end of the elastic strip 87 is immediately inserted into the interior of the brake card interface 88, thereby braking the guide roller 82, making it difficult for the wire to move in the opposite direction, so that the wire can only move in the discharge direction and is not easily disordered.

[0066] Moreover, when the wire on the pay-off wheel 61 is finished, the cylinder 72 can be started again to work, and the telescopic end of the cylinder 72 can be retracted to apply a pulling force to the right-angle plate 73, so that the right-angle plate 73 drives the semi-circular top moving member 74 to rotate counterclockwise to adjust the angle, thereby disengaging the semi-circular top moving member 74 from the end of the pay-off wheel 61, making it easy to remove the pay-off wheel 61.
