Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically to a tension adjustment device and an automatic winding machine. Background Technology

[0002] Power transformers are the core hub of modern power systems. The core component of a power transformer is its coil, which is typically composed of alternating layers of insulating paper and metal wire, possessing high electrical insulation performance and mechanical strength. Transformer coils are usually manufactured using winding machines.

[0003] However, during the winding process, the wire winding machine needs to maintain appropriate tension of the material (wire / insulating paper). When the wire passes through the wire winding mechanism, the reciprocating movement of the wire winding mechanism can cause sudden tension changes in the wire during the winding process, which affects the winding effect of the coil.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a tension adjustment device and an automatic wire winding machine to solve the technical problem of sudden tension changes in metal wires during the winding process in related technologies.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: a tension adjustment device is provided, comprising: an adjustment seat, which is movably arranged along the height direction, a sensing component is provided on the adjustment seat, a material to be wound is inserted into the sensing component, the sensing component is used to detect the tension state of the material to be wound, and the adjustment seat moves along the height direction according to the tension state of the material to be wound; a damper, which is installed on a guide wheel for providing the material to be wound, and the damper is connected to the adjustment seat. When the adjustment seat moves along the height direction, the damping magnitude of the damper changes accordingly, so as to change the tension state of the material to be wound led out by the guide wheel.

[0007] Furthermore, the damper includes a friction belt and a friction wheel. The friction belt is connected to the adjusting seat, and the friction wheel is coaxially arranged with the guide wheel. The friction belt is wound around the friction wheel. When the adjusting seat moves along the height direction, the contact area between the friction belt and the friction wheel changes, and the damping magnitude of the damper changes accordingly.

[0008] Furthermore, the damper includes a counterweight, which is connected to the end of the friction band away from the adjusting seat.

[0009] Furthermore, the adjustment seat includes a slider, which is slidably mounted on the guide rail.

[0010] Furthermore, the tension adjustment device includes a limiting component, which is located at the top of the guide rail and is positioned to abut against the slider.

[0011] Furthermore, the sensing component includes a first guide wheel and a second guide wheel, both of which are rotatably mounted on an adjusting seat. The first guide wheel and the second guide wheel are arranged opposite to each other, and the material to be wound is accommodated between the first guide wheel and the second guide wheel, wherein the first guide wheel is in rolling contact with the material to be wound.

[0012] An automatic wire winding machine includes the aforementioned tension adjustment device.

[0013] Furthermore, the tension adjustment device is located between the guide wheel and the movable trigger, and the material to be wound enters the movable trigger after passing through the tension adjustment device. Beneficial effects: 1. The tension adjustment device provided in this embodiment converts the tension state of the material to be wound into a vertical displacement of the adjustment seat through the movable setting of the adjustment seat and the linkage of the sensing component. Then, the damper converts this displacement into an adjustment of the resistance to the wire feeding wheel. Real-time automatic tension adjustment can be achieved without a complex electrical control system, effectively suppressing the sudden tension phenomenon caused by equipment start-up, shutdown, reversal, or uneven material. Through the adjustment feedback mechanism, damping adjustment is performed according to the real-time tension state, ensuring that the material to be wound maintains a stable and uniform tension state throughout the high-speed winding process. This significantly improves the winding quality and product consistency, and solves the technical problem of sudden tension changes in metal wires during the winding process in related technologies.

[0014] 2. By adjusting the up-and-down movement of the adjusting seat, the friction belt moves synchronously, changing the engagement position of the friction belt on the friction wheel, and thus changing the wrap angle between the friction belt and the friction wheel. The increase or decrease of the wrap angle directly leads to the increase or decrease of the contact arc length between the friction belt and the friction wheel, that is, the dynamic change of the contact area.

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] According to an embodiment of this utility model, a tension adjusting device is provided. Please refer to [link / reference]. Figures 1 to 7 The device includes: an adjusting seat 6, which is movably arranged along the height direction, and a sensing component is provided on the adjusting seat 6. The sensing component contains the material to be wound, and the sensing component is used to detect the tension state of the material to be wound. The adjusting seat 6 moves along the height direction according to the tension state of the material to be wound; and a damper 7, which is installed on the guide wheel 414 for providing the material to be wound. The damper 7 is connected to the adjusting seat 6. When the adjusting seat 6 moves along the height direction, the damping magnitude of the damper 7 changes accordingly to change the tension state of the material to be wound led out by the guide wheel 414.

[0019] The adjusting seat 6 is movably arranged along the height direction. The movement of the adjusting seat 6 directly responds to the tension change of the material to be wound. The adjusting seat 6 can adjust its own height position in real time according to the tension change of the material to be wound. The adjusting seat 6 is equipped with a sensing component, in which the material to be wound is threaded, for real-time detection of the tension state of the material. For example, when the tension of the material to be wound increases, the material to be wound threaded in the sensing component is in a straight state, pushing the adjusting seat 6 upward; when the tension decreases, the material to be wound threaded in the sensing component is in a relaxed state, and the adjusting seat 6 moves downward under the action of gravity.

[0020] Specifically, the damping magnitude of the damper 7 changes continuously as the height of the adjusting seat 6 moves. When the height of the adjusting seat 6 changes, the damping magnitude of the damper 7 changes accordingly, thereby changing the rotational resistance and directional resistance of the guide wheel 414 when releasing the material, thus controlling the wire feeding resistance of the guide wheel 414 and ultimately stabilizing the tension of the material to be wound.

[0021] The tension adjustment device provided in this embodiment converts the tension state of the material to be wound into a vertical displacement of the adjustment seat 6 through the movable setting of the adjustment seat 6 and the linkage of the sensing component. Then, the damper 7 converts this displacement into an adjustment of the wire feeding resistance of the guide wheel 414, forming an adjustment feedback process of "tension sensing - displacement response - damping adjustment". It can realize real-time automatic tension adjustment without the need for a complex electrical control system, effectively suppressing the phenomenon of sudden tension changes caused by equipment start-up and shutdown, reversal, or uneven material. Through the adjustment feedback mechanism, the damping adjustment is performed according to the real-time tension state, ensuring that the material to be wound maintains a stable and uniform tension state throughout the high-speed winding process, significantly improving the winding quality and product consistency, and solving the technical problem of sudden tension changes in metal wires during the winding process in related technologies.

[0022] In the tension adjustment device of this embodiment, see Figure 1-3 The damper 7 includes a friction belt 71 and a friction wheel 72. The friction belt 71 is connected to the adjusting seat 6. The friction wheel 72 is coaxially arranged with the guide wheel 414. The friction belt 71 is wound around the friction wheel 72. When the adjusting seat 6 moves along the height direction, the contact area between the friction belt 71 and the friction wheel 72 changes, and the damping magnitude of the damper 7 changes accordingly.

[0023] The up-and-down movement of the adjusting seat 6 drives the friction belt 71 to move synchronously, changing the engagement position of the friction belt 71 on the friction wheel 72, and thus changing the wrap angle between the friction belt and the friction wheel. The increase or decrease of the wrap angle directly leads to the increase or decrease of the contact arc length between the friction belt 71 and the friction wheel 72, that is, the dynamic change of the contact area.

[0024] When the wrap angle increases, the contact area increases, the braking effect of the friction belt 71 on the friction wheel 72 is enhanced, the generated frictional torque increases, and the resistance to wire feeding on the guide wheel 414 increases. Conversely, when the wrap angle decreases, the contact area decreases, the frictional torque decreases, the damping force decreases, and the resistance to wire feeding on the guide wheel 414 decreases. Since the friction wheel 72 and the guide wheel 414 are coaxially arranged, the change in frictional torque is directly transmitted to the guide wheel 414, changing its rotational resistance, and thus adjusting the tension state of the material to be wound by the guide wheel 414.

[0025] The displacement of the adjusting seat 6 is converted into precise control of the damping force through mechanical linkage, without the need for external energy or complex control system. The variable design of the wrap angle between the friction belt 71 and the friction wheel 72 realizes the adaptive adjustment of the damping force, effectively maintaining the tension of the material to be wound during the winding process.

[0026] In some embodiments, the friction belt may be made of rubber, and the friction wheel may be made of metal.

[0027] In the tension adjustment device of this embodiment, see Figure 1 The damper 7 includes a counterweight 73, which is connected to the end of the friction belt 71 furthest from the adjusting seat 6. By setting the counterweight 73 at the free end of the friction belt 71, it is ensured that the friction belt 71 always maintains effective contact with the friction wheel 72. The direction of gravity of the counterweight 73 is consistent with the extension direction of the friction belt 71, forming a continuous downward pulling force, so that the friction belt 71 maintains the preset initial tension state, thus ensuring the damping adjustment effect.

[0028] When the adjusting seat 6 moves upward, the friction band 71 is pulled upward, and the counterweight 73 rises accordingly. When the adjusting seat 6 moves downward, the friction band 71 is pulled downward, and the counterweight 73 moves downward under the action of gravity.

[0029] In the tension adjustment device of this embodiment, see Figure 1 The adjusting seat 6 includes a slider 61, which is slidably mounted on the guide rail 9. By setting the slider 61 on the adjusting seat 6 and forming a sliding engagement with the guide rail 9, precise motion guidance is provided for the movement of the adjusting seat 6 in the height direction, reducing the coefficient of friction of the moving adjusting seat 6, and enabling the adjusting seat 6 to quickly complete the height adjustment according to the tension change.

[0030] In the tension adjustment device of this embodiment, see Figure 1 The tension adjustment device includes a limiting component 91, which is located at the top of the guide rail 9. The limiting component 91 and the slider 61 are grounded together.

[0031] In some embodiments, a limit device is provided at the top of the guide rail to prevent the slider 61 from moving excessively and causing the slider 61 to disengage from the guide rail.

[0032] In the tension adjustment device of this embodiment, see Figure 1 The sensing component includes a first guide wheel 81 and a second guide wheel 82. Both the first guide wheel 81 and the second guide wheel 82 are rotatably mounted on the adjusting seat 6. The first guide wheel 81 and the second guide wheel 82 are arranged opposite to each other. The material to be wound is accommodated between the first guide wheel 81 and the second guide wheel 82. The first guide wheel 81 is in rolling contact with the material to be wound.

[0033] Specifically, the first guide wheel 81 is in direct rolling contact with the material to be wound. When the material is taut, it maintains a relatively horizontal position, and the tension is sufficient to support the first guide wheel 81. At this time, the adjusting seat 6 is in a relatively high position. When the tension of the material decreases, it is insufficient to support the first guide wheel 81 and keep it in its initial position. Under its own weight, the adjusting seat 6 moves downward, thereby adjusting the damping magnitude of the damper 7. When the material is taut again, it pulls the first guide wheel 81, which in turn drives the adjusting seat 6 to move upward.

[0034] For example in Figure 3 In the middle, the downward movement of the adjusting seat 6 causes the friction belt 71 to move downward; The working process of the tension adjusting device provided in this embodiment of the present invention is as follows: In the initial state, the material to be wound is led out from the guide wheel 414, passes through the sensing component of the tension adjustment device in sequence, and enters the moving trigger 5 for winding. At this time, the adjusting seat 6 is in the initial height position. One end of the friction belt 71 is connected to the adjusting seat 6, and the other end is connected to the counterweight 73. It is wound on the friction wheel 72, which is coaxial with the guide wheel 414, to form an initial wrap angle A1, so that the material to be wound is kept taut.

[0035] join Figure 3 When the tension of the material to be wound decreases, the supporting force of the material on the first guide wheel 81 weakens, which is insufficient to balance the weight of the adjusting seat 6. Under the combined action of its own weight and the counterweight 73, the adjusting seat 6 moves downward along the guide rail 9. The descent of the adjusting seat 6 causes the friction belt 71 to move downward, increasing its wrap angle on the friction wheel 72, forming a wrap angle A2. This leads to an increase in the contact area and frictional torque, which in turn increases the wire feeding resistance of the guide wheel 414, causing the tension to gradually rise.

[0036] As the tension of the material to be wound gradually recovers, the material pulls the adjusting seat 6 upward along the guide rail 9. The rise of the adjusting seat 6 causes the friction belt 71 connected to it to move upward synchronously, reducing the wrap angle of the friction belt 71 on the friction wheel 72, thereby reducing the friction torque and extending the service life of the friction belt.

[0037] In summary, the tension adjustment device of this embodiment senses the tension change in real time through the sensing component, drives the adjustment seat 6 to move up and down, and then dynamically adjusts the damping magnitude by changing the wrap angle between the friction belt 71 and the friction wheel 72, effectively solving the technical problem of sudden tension changes during the winding of metal wire.

[0038] In the automatic wire winding machine of this embodiment, see... Figure 4 The automatic wire winding machine includes the aforementioned tension adjustment device.

[0039] In the automatic wire winding machine of this embodiment, the tension adjustment device is disposed between the guide wheel 414 and the movable trigger 5. The material to be wound enters the movable trigger 5 through the tension adjustment device.

[0040] By arranging the tension regulating device between the discharge side of the guide wheel 414 and the feed side of the moving trigger 5, the material to be wound is regulated by the tension regulating device before entering the winding actuator, i.e., the moving trigger 5, to ensure that the material entering the moving trigger 5 has a stable and uniform tension state.

[0041] The automatic wire winding machine in this embodiment includes: a winding assembly 1; a paper feeding assembly 2, which is installed on one side of the winding assembly 1; a wire feeding assembly 3, which is reciprocatingly linearly connected to the top of the paper feeding assembly 2; and a feeding assembly 4, which is installed on one side of the paper feeding assembly 2. The paper feeding assembly 2 is located between the winding assembly 1 and the feeding assembly 4, and the feeding assembly 4 is provided with a moving trigger 5. The moving trigger 5 is used to sense the position of the wire feeding assembly 3 so as to control the feeding assembly 4 to follow the movement direction of the wire feeding assembly 3 and perform reciprocating linear motion in the same direction.

[0042] Using the above device, when coil winding is required, the winding assembly 1 is started. The winding assembly 1 drives the material of the feeding assembly 4 to pass through the wire laying assembly 3 and the paper laying assembly 2 at the same time. On the one hand, it helps the material to maintain stable operation during the transmission process. On the other hand, the wire laying assembly 3 is connected to the top of the paper laying assembly 2 in a reciprocating linear motion. The feeding assembly 4 is horizontally installed on one side of the paper laying assembly 2, so that the paper laying assembly 2 is located between the winding assembly 1 and the feeding assembly 4. The feeding assembly 4 is equipped with a moving trigger 5, which is used to control the feeding assembly 4 to follow the movement direction of the wire laying assembly 3 and perform reciprocating linear motion in the same direction. This can simultaneously drive the wire and the insulating paper to be wound in an orderly manner on the winding assembly 1.

[0043] In this embodiment, the feeding assembly 4 includes: a feeding element 41, which is reciprocally linearly connected to the feeding base 42; a moving trigger 5 disposed on the feeding element 41; the feeding element 41 is used to feed the wire. The feeding base 42.

[0044] It should be noted that a servo motor is installed on the feeding base 42 to drive the pinion to rotate. The pinion meshes with the long rack fixed on the feeding base 42. The rotation of the gear drives the feeding component 41 to move linearly along the rack.

[0045] The feeding component 41 includes: a feeding bracket 411; a first shaft 412 connected to the feeding bracket 411, on which a guide wheel 414 for winding the wire is provided; and a second shaft 413 connected to the feeding bracket 411, on which a guide wheel 415 for winding insulating paper is provided.

[0046] This allows for the conveying of insulating paper and wires.

[0047] In this embodiment, the first shaft 412 is disposed above the second shaft 413; the movable trigger 5 is located between the first shaft 412 and the cable assembly 3; the movable trigger 5 is located between the guide wheel 414 and the cable assembly 3.

[0048] By adopting the above settings, the feeding component 4 becomes more integrated and makes better use of space.

[0049] The moving trigger 5 includes: position sensors 51: two position sensors 51 are mounted side by side on the feeding bracket 411 and are parallel to the guide wheel 414; trigger rods 52: one end of each trigger rod 52 is rotatably connected to the two position sensors 51, and the middle of the two trigger rods 52 forms a gap for the guide wire to pass through. The left and right movement of the two trigger rods 52 will drive the guide wheels of the two trigger rods 52 to rotate in the corresponding direction.

[0050] Using the above device, when the wire moves left and right on the wiring assembly 3, it will cause the wire trigger rod 52 to move left and right. When the wire moves to the left, it will cause the trigger rod 52 to move to the left, which will control the trigger element to control the feeding bracket 411 to move to the left. When the wire starts to move to the right, the left trigger rod 52 returns to the center, which will cause the trigger rod 52 to move to the right, which will control the moving trigger element 5 to control the feeding bracket 411 to move to the right. On the one hand, the wire wheel 414 will move in the same direction as the wiring assembly 3, reducing the rapid change of wire tension. On the other hand, since the wire wheel 414 and the paper guide wheel 415 are installed on the feeding bracket 411, when the wire triggers the feeding assembly 4 to move, it will also drive the paper guide wheel 415 to feed the insulating paper tape, realizing the winding of the wire and the insulating paper tape.

[0051] It should be noted that the combination of the two position sensors 51 and their trigger rods 52 arranged side by side is located on the same plane as the guide wheel 414, and a cylindrical guide wheel is sleeved on the trigger rod 52. In addition to using a dual trigger mechanism, a single trigger mechanism can also be used to realize the reciprocating motion of the feeding assembly 4.

[0052] In this embodiment, see Figure 6 The moving trigger 5 includes: a limiting frame 53: the limiting frame 53 is provided with two spaced guide wheels; the axis of the guide wheels on the limiting frame 53 is perpendicular to the guide wheel on the trigger rod 52.

[0053] By adopting the above configuration, the structure of the trigger can be more integrated, thereby accurately sensing the position. The axis of the guide wheel on the limit frame 53 is perpendicular to the guide wheel on the trigger rod 52, which makes the wiring more stable and will not affect the sensing of the position sensor 51.

[0054] The paper feeding assembly 2 includes: a paper feeding bracket 21; guide shafts 22: several guide shafts 22 are fixedly connected to the paper feeding bracket 21; the top of the paper feeding bracket 21 is provided with a slide rail 211 and a lead screw 212 parallel to the guide shafts 22, and the slide rail 211 and the lead screw 212 are used to cooperate with the cable feeding assembly 3 to perform reciprocating motion.

[0055] It should be noted that three guide shafts 22 arranged in a regular vertical pattern are used to guide the insulating paper, ensuring that the insulating paper maintains a certain tension and stability during movement. The top of the paper feeding bracket 21 is provided with two slide rails 211 parallel to the guide shafts 22, and a lead screw 212 is installed between the two slide rails 211.

[0057] In this embodiment, the winding assembly 1 includes: a control console 11; a rotating shaft 12 for driving the workpiece to rotate; and a positioning shaft 13 for positioning the workpiece.

[0058] Working principle: Material preparation and threading: Install the spools of enameled wire, etc., onto the wire rollers 414 of the feeding assembly 4. Install the insulating paper rolls onto the paper guide rollers 415 of the feeding assembly 4. Lead the wires and insulating paper tapes out from their respective rollers and thread them along the preset path: The wire is drawn out from the wire wheel 414, passes through the gap between the two trigger rods 52 of the movable trigger 5, passes through one or more wire wheels 32 of the wire assembly 3, and finally reaches the rotating workpiece for winding.

[0059] Insulating paper tape: It is drawn out from the paper guide roller 415, passes around several guide shafts 22 on the paper discharge assembly 2, and finally reaches the rotating workpiece. It is wound synchronously with the wire and is usually used for interlayer insulation.

[0060] Cable routing process: The drive mechanism of the cable routing assembly 3 is activated. The slider 33 at the bottom of the cable routing bracket 31 slides on the slide rail 211 at the top of the paper routing bracket 21. The lead screw 212 rotates, driving the cable routing bracket 31 and its cable routing wheel 32 to reciprocate linearly along the slide rail 211.

[0061] Guided by the wire guide wheel 32, the wires are evenly and orderly arranged on the rotating workpiece as the wire guide bracket 31 moves left and right.

[0062] Movement triggering and feeding synchronization: When the wire moves to the left under the guidance of the wire guide wheel 32: the wire will push the trigger rod 52 on the left side of the moving trigger 5 to contact the guide wheel on the trigger rod.

[0063] The rotation of the left trigger lever 52 triggers the position sensor 51 connected to it.

[0066] The rotation of the right trigger lever 52 triggers the position sensor 51 connected to it.

[0067] Position sensor 51 sends a signal.

[0068] The feeding component follows the movement: The signal from position sensor 51, which shifts left or right, is sent to the control system on feeding base 42.

[0069] The control system drives the servo motor on the feeding base 42.

[0070] A servo motor drives a small gear to rotate.

[0071] The pinion meshes with the long rack fixed on the feeding base 42.
