Description

Technical Field

[0001] This invention relates to the field of transformer or reactor manufacturing technology, and more particularly to equipment for manufacturing enameled wire windings for transformers or reactors. Background Technology

[0002] Existing equipment for manufacturing enameled wire windings for transformers or reactors typically uses multiple independent motors to drive the conveying, wire laying, and stranding mechanisms separately. In actual production, due to response delays and speed deviations between the motors, it is difficult for multiple actuators to achieve strict synchronous operation. This easily leads to tension fluctuations and accumulation of the enameled wire during conveying, affecting the tightness and uniformity of the windings. Furthermore, the transmission links of traditional equipment are complex and occupy a large space, hindering compact production line layouts. In the stranding stage, the enameled wire experiences significant frictional resistance as it passes through metal guides, easily generating localized high temperatures, causing insulation damage or coil surface roughness, and reducing product quality. Simultaneously, existing equipment has poor adaptability to enameled wires of different diameters, requiring manual adjustment of mechanical components when changing specifications, resulting in low efficiency.

[0003] To address the problems of multi-motor synchronization difficulties, large equipment size, parallel strand friction heating, and insufficient adaptability in the existing technologies, this invention proposes a transformer or reactor enameled wire winding manufacturing equipment. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides a transformer or reactor enameled wire winding manufacturing equipment, which aims to improve the problems of existing winding equipment, such as difficulty in synchronizing multiple motors, complex transmission links, large equipment size, frictional heating of parallel strands, and poor adaptability to enameled wires of different diameters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Transformer or reactor enameled wire winding manufacturing equipment includes a mounting base for supporting the transformer, a transmission assembly fixedly connected to the top of the mounting base, and a stranding assembly mounted in the middle of the upper surface of the mounting base.

[0007] The transmission assembly includes two protective frames for protection. Two drive pulleys are vertically mounted on the lower rear side of the inner wall of the two protective frames. A first set of transmission pulleys is arranged inside the protective frame at the upper end of the two drive pulleys. A second set of transmission pulleys is installed on the front side of the inner wall of the protective frame located between the drive pulleys and the first set of transmission pulleys. Three rotating shafts pass through the centers of the two drive pulleys, the first set of transmission pulleys, and the second set of transmission pulleys, respectively. A primary conveying component is installed on the surface of the rotating shaft located in the middle of the first set of transmission pulleys. A secondary conveying component is installed on the surface of the rotating shaft located in the middle of the two drive pulleys. A threaded groove is formed on the surface of the rotating shaft located in the middle of the second set of transmission pulleys, and a following sliding component is installed through the threaded groove. Two annular grooves are formed on the outer ring surface of the two drive pulleys. The two drive pulleys and the first set of transmission pulleys are connected by a first set of transmission belts, and the two drive pulleys and the second set of transmission pulleys are connected by a second set of transmission belts.

[0008] As a further description of the above technical solution: A servo motor is horizontally mounted on one side of the drive pulley on the left side. The servo motor drives the drive pulley to rotate. The first set of transmission belts and the second set of transmission belts are respectively embedded in two annular grooves opened on the outer ring surface of the drive pulley, which drives the first set of transmission pulleys and the second set of transmission pulleys to rotate synchronously. Through a single power source, the primary conveying component, the secondary conveying component and the following sliding component are synchronously driven to operate in coordination. This achieves strict speed matching and complete synchronization of the actions of multiple sets of actuators during the winding manufacturing process, thereby reducing the number of power sources, simplifying the transmission link, compressing the overall size of the equipment, and improving the transmission accuracy and operational stability.

[0009] As a further description of the above technical solution: the primary conveying assembly includes a gear column sleeved on the surface of a rotating shaft in the middle of the first set of transmission pulleys. Multiple cylindrical gear sleeves are sleeved on the surface of the gear column. Each cylindrical gear sleeve is connected to a locking disc. Each locking disc has four annularly arranged arc holes on its left and right sides. Two reciprocating springs are connected to the front and rear sides of the inner wall of each arc hole. Two damping blocks are connected to the front and rear ends of each reciprocating spring.

[0010] As a further description of the above technical solution: four pressure shafts are installed along the middle of the front and rear of every two reciprocating springs, and multiple rubber columns arranged in a ring are provided on the outer ring surface of each pressure shaft. Two T-shaped discs are fixedly connected to the left and right ends of each pressure shaft. A primary transmission roller is installed in the middle of the two T-shaped discs. The two T-shaped discs and the primary transmission roller are fixedly connected by fixing bolts.

[0011] As a further description of the above technical solution: the secondary conveying assembly includes multiple cylindrical mounting sleeves fitted onto the rotating shaft surface in the middle of the drive pulley. Each cylindrical mounting sleeve has six annularly arranged telescopic grooves vertically opened on its outer ring surface. Each telescopic groove has multiple sets of vertically installed spring damping rods fixedly connected to its inner wall lower surface.

[0012] As a further description of the above technical solution: each of the spring damping rods has a lifting plate connected to one end away from the inner wall seal of the telescopic groove; each of the cylindrical mounting sleeves has a secondary transmission roller coaxially sleeved on its outer wall; each of the secondary transmission rollers has a square slot on its inner wall ring surface; and the end of each lifting plate away from the spring damping rod is in floating contact with the square slot.

[0013] As a further description of the above technical solution: the following sliding assembly includes a sliding mounting sleeve with a hexagonal outer wall, coaxially sleeved on the surface of a rotating shaft in the middle of the second set of transmission pulleys. An internal threaded sleeve is installed inside the sliding mounting sleeve via a supporting rotating shaft. The internal threaded sleeve is threadedly engaged with the threaded groove on the surface of the rotating shaft. Two supporting cavities are opened on the left and right sides of the inner wall of the sliding mounting sleeve. Two connecting threaded sleeves are vertically installed in each supporting cavity. Two sets of supporting threaded sleeves are provided through all six sides of the outer wall of the sliding mounting sleeve between the two connecting threaded sleeves. A sliding groove is installed perpendicular to the bottom of the sliding mounting sleeve. Two sliders are slidably arranged inside the sliding groove. A threaded connecting rod is connected to the top of each slider.

[0014] As a further description of the above technical solution: Adjusting bolts are rotatably installed inside both connecting threaded sleeves and both sets of supporting threaded sleeves. The lower end of the adjusting bolt located inside the two connecting threaded sleeves is connected to the threaded connecting rod. Each adjusting bolt located inside the two sets of supporting threaded sleeves passes through one end face of the sliding mounting sleeve and is fixedly connected to a trapezoidal block. Two supporting rotating shafts are vertically installed inside the sliding mounting sleeve on the opposite side of the two supporting cavities, and an internal threaded sleeve is installed in the middle of the two supporting rotating shafts.

[0015] As a further description of the above technical solution: the parallel stranding assembly includes a mounting circular groove installed in the middle of the upper surface of the mounting base. Two stationary plates are connected to the inner wall of the mounting circular groove. A rotating shaft is installed in the middle of the upper surface of the inner wall of the mounting circular groove. A vertical rotating column is vertically installed in the middle of the rotating shaft. A rotating ring is installed at the lower end of the outer ring surface of the vertical rotating column. Two rotating plates are connected to the surface of the rotating ring. Two sets of vertically installed rotating rollers are passed through the inner ends of the two stationary plates away from the mounting circular groove and the inner ends of the two rotating plates away from the rotating ring. The surfaces of each pair of rotating rollers are fixedly connected by a spring plate. A parallel stranding cylinder is connected to the upper end of the vertical rotating column. Two transition rings are connected to the front and rear ends of the parallel stranding cylinder. The inner wall of the parallel stranding cylinder is made of ceramic material, which can reduce frictional heat generation during the parallel stranding process and improve the smoothness of parallel stranding.

[0016] As a further description of the above technical solution: a controller is installed on the right side surface of the mounting base, the right ends of the three rotating shafts all penetrate through the protective frame, and locking sleeves are connected to the ends of the three rotating shafts.

[0017] The present invention has the following beneficial effects:

[0018] 1. In this invention, a single power source transmission assembly is adopted. A servo motor is horizontally mounted and drives the active pulley to rotate. The first set of transmission belts and the second set of transmission belts are respectively embedded in two annular grooves opened on the outer ring surface of the active pulley, which drives the first set of transmission pulleys and the second set of transmission pulleys to rotate synchronously. This drives the primary conveying assembly, the secondary conveying assembly and the following sliding assembly to operate in coordination. This achieves strict speed matching and complete synchronization of multiple actuators in the winding manufacturing process, and achieves the effects of reducing the number of power sources, simplifying the transmission link, compressing the overall size of the equipment, and improving the transmission accuracy and operational stability.

[0019] 2. In this invention, by setting a floating cylindrical mounting sleeve with a spring damping rod in the secondary conveying assembly, the spring damping rod pushes the lifting plate to float and connect with the square slot on the inner wall of the secondary transmission roller, thereby achieving adaptive flexible conveying of enameled wires of different diameters; at the same time, the use of a ceramic inner wall-mounted stranding cylinder and an adaptively tensioned rotating roller in the stranding assembly allows the multi-strand enameled wires to be integrated and tightened twice during the stranding process, thereby reducing the operating noise caused by traditional rigid transmission, reducing the heat generated by stranding friction, and improving the winding quality.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figures 1-11 An embodiment of the transformer or reactor enameled wire winding manufacturing equipment provided by the present invention:

[0035] Transformer or reactor enameled wire winding manufacturing equipment includes a mounting base 1 for supporting the transformer, a transmission assembly 2 fixedly connected to the top of the mounting base 1, and a stranding assembly 6 mounted in the middle of the upper surface of the mounting base 1.

[0036] As a further improvement to the above technical solution: the transmission assembly 2 includes two protective frames 201 for protection. Two drive pulleys 202 are vertically mounted on the lower rear side of the inner wall of the two protective frames 201. A first set of transmission pulleys 203 is disposed inside the protective frame 201 at the upper end of the two drive pulleys 202. A second set of transmission pulleys 204 is installed on the front side of the inner wall of the protective frame 201 located between the drive pulleys 202 and the first set of transmission pulleys 203. Three rotating shafts 205 pass through the centers of the two drive pulleys 202, the first set of transmission pulleys 203, and the second set of transmission pulleys 204, respectively. A primary conveying assembly 3 is mounted on the surface of the rotating shaft 205 in the middle of the 3. A secondary conveying assembly 4 is mounted on the surface of the rotating shaft 205 located in the middle of the two driving pulleys 202. A threaded groove 206 is formed on the surface of the rotating shaft 205 located in the middle of the second set of transmission pulleys 204. A following sliding assembly 5 is mounted on the surface of the threaded groove 206. Two annular grooves 209 are formed on the outer ring surface of the two driving pulleys 202. The two driving pulleys 202 and the first set of transmission pulleys 203 are connected by a first set of transmission belts 207. The two driving pulleys 202 and the second set of transmission pulleys 204 are connected by a second set of transmission belts 208.

[0037] A servo motor 210 is horizontally mounted on one side of the drive pulley 202 on the left side. The servo motor 210 drives the drive pulley 202 to rotate. The first set of transmission belts 207 and the second set of transmission belts 208 are respectively embedded in the two annular grooves 209 opened on the outer ring surface of the drive pulley 202, which drive the first set of transmission pulleys 203 and the second set of transmission pulleys 204 to rotate synchronously. Through a single power source, the primary conveying component 3, the secondary conveying component 4 and the following sliding component 5 are synchronously driven to operate in coordination. This achieves strict speed matching and complete synchronization of the actions of multiple actuators in the winding manufacturing process, thereby reducing the number of power sources, simplifying the transmission link, compressing the overall size of the equipment, and improving the transmission accuracy and operational stability.

[0038] Specifically, a servo motor 210 is horizontally mounted on the outside of the left protective frame 201, and its output shaft is directly connected to the central key of the left drive pulley 202 to achieve direct torque transmission. Two parallel annular grooves 209 machined on the outer ring surface of the drive pulley 202 respectively accommodate the inner tooth surfaces of the first set of transmission belts 207 and the second set of transmission belts 208, preventing axial displacement of the belts during operation. The first set of transmission belts 207 transmits the rotational motion of the left drive pulley 202 to the first set of transmission pulleys 203, while the second set of transmission belts 208 transmits the same rotational motion to the second set of transmission pulleys 204, thus ensuring that the two driven pulleys rotate synchronously at the same angular velocity. Because the first set of transmission pulleys 203 and the second set of transmission pulleys 204 are respectively mounted on different rotating shafts 205, and these three rotating shafts 205 are respectively connected to the primary conveying component 3, the secondary conveying component 4, and the following sliding component 5, strict synchronization of the three actuators in time and space is achieved, avoiding the phase difference and speed fluctuation that may occur in traditional multi-motor drives. The controller 7 is connected to the servo motor 210 driver through a signal line, receives the speed parameters set by the operator, and feeds back the encoder signal in real time to form a closed-loop control, ensuring that the entire transmission system can maintain stable synchronization performance when the load changes.

[0039] As a further improvement to the above technical solution: the primary conveying assembly 3 includes a gear post 301 sleeved on the surface of the rotating shaft 205 in the middle of the first set of transmission pulleys 203. Multiple cylindrical gear sleeves 302 are sleeved on the surface of the gear post 301. Each cylindrical gear sleeve 302 is connected to a locking disc 303. Each locking disc 303 has four circularly arranged arc holes 304 on its left and right sides. Two reciprocating springs 305 are connected to the front and rear sides of the inner wall of each arc hole 304. Two damping blocks 306 are connected to the front and rear ends of each reciprocating spring 305.

[0040] Four pressure shafts 307 are installed along the middle of the front and rear of every two reciprocating springs 305. Each pressure shaft 307 has multiple rubber columns 308 arranged in a ring on its outer ring surface. Two T-shaped discs 309 are fixedly connected to the left and right ends of each pressure shaft 307. A primary transmission roller 310 is installed in the middle of the two T-shaped discs 309. The two T-shaped discs 309 and the primary transmission roller 310 are fixedly connected by fixing bolts 311.

[0041] Specifically, the gear column 301 rotates synchronously via the rotating shaft 205 in the middle of the first set of transmission pulleys 203. The outer surface of the gear column 301 meshes with the internal teeth of multiple cylindrical gear sleeves 302, ensuring that each cylindrical gear sleeve 302 rotates at a uniform speed. Each cylindrical gear sleeve 302 transmits rotational power to the locking disc 303 body through a locking disc 303 fixed to its outer surface. Reciprocating springs 305 and damping blocks 306 are installed in the four arc-shaped holes 304 on both sides of the locking disc 303. During rotation, the elastic deformation of the springs and the frictional energy dissipation of the damping blocks 306 absorb the instantaneous impact and vibration from the traction of the enameled wire. Four horizontally penetrating pressure shafts 307 span the front and rear middle sections of every two reciprocating springs 305. The rubber pillars 308 densely arranged on the outer ring surface of the pressure shafts 307 maintain elastic contact with the reciprocating springs 305 and damping blocks 306, further attenuating high-frequency micro-amplitude vibrations. The T-shaped discs 309 at both ends of the pressure shaft 307 are rigidly connected to the primary drive roller 310 via fixing bolts 311. This ensures that the smooth rotational torque after vibration damping is ultimately transmitted to the primary drive roller 310, achieving uniform and low-vibration conveying of multiple strands of enameled wire from the material tray to the next process. If the conveying tension needs to be adjusted, the speed of the servo motor 210 can be adjusted via the controller 7, thereby changing the linear speed of the primary drive roller 310 to adapt to the conveying requirements of enameled wires of different specifications.

[0042] As a further improvement to the above technical solution: the secondary conveying assembly 4 includes multiple cylindrical mounting sleeves 401 sleeved on the surface of the rotating shaft 205 in the middle of the two drive pulleys 202. Each cylindrical mounting sleeve 401 has six annularly arranged telescopic grooves 402 vertically opened on its outer ring surface. Each telescopic groove 402 has multiple sets of vertically installed spring damping rods 403 fixedly connected to the lower surface of its inner wall.

[0043] Each spring damping rod 403 has a lifting plate 406 connected to the end away from the inner wall seal of the telescopic groove 402. Each cylindrical mounting sleeve 401 has a secondary transmission roller 404 coaxially mounted on its outer wall. Each secondary transmission roller 404 has a square slot 405 on its inner wall ring surface. Each lifting plate 406 has a floating contact connection with the square slot 405 at the end away from the spring damping rod 403.

[0044] Specifically, the rotating shaft 205 in the middle of the drive pulley 202 drives multiple cylindrical mounting sleeves 401 to rotate synchronously. Six vertically formed expansion slots 402 on the outer circumference of each cylindrical mounting sleeve 401 serve as accommodating spaces. Multiple sets of vertical spring damping rods 403 are fixedly installed on the lower inner wall of each expansion slot 402. Utilizing the elastic expansion and contraction characteristics of the spring damping rods 403, the end furthest from the sealing of the expansion slot 402 consistently applies an outward thrust to the lifting plate 406. The end of the lifting plate 406 furthest from the spring damping rods 403 forms a floating contact connection with the square groove 405 on the inner circumference of the secondary drive roller 404. Thus, during rotation, the automatic expansion and contraction of the spring damping rods 403 compensates for the radial gap between the secondary drive roller 404 and the cylindrical mounting sleeves 401, enabling the secondary drive roller 404 to adapt to changes in radial pressure caused by the passage of enameled wires of different diameters. Multiple strands of enameled wire are individually conveyed and naturally converged by passing around the rear surface of each secondary drive roller 404. This floating transmission structure achieves adaptive pressing and conveying of the enameled wire on the surface of the secondary drive roller 404, avoiding slippage or jamming caused by changes in wire diameter in traditional fixed-diameter drive rollers. This results in smooth transmission of multiple strands of enameled wire and preliminary pre-coiling. This secondary conveying assembly 4 requires no additional sensors or electronic controls, relying entirely on the elastic floating characteristics of the mechanical structure for self-adaptation, simplifying the complexity of the control system. If adjustment of the pre-coiling tension is required, the speed of the servo motor 210 can be adjusted via the controller 7, thereby changing the linear speed of the secondary drive roller 404 to adapt to the conveying requirements of different specifications of enameled wire.

[0045] As a further improvement to the above technical solution: the following sliding component 5 includes a sliding mounting sleeve 501 with a hexagonal outer wall, which is coaxially sleeved on the surface of the rotating shaft 205 in the middle of the second set of transmission pulleys 204. The sliding mounting sleeve 501 has an internal threaded sleeve 511 installed inside through a supporting rotating shaft 510. The internal threaded sleeve 511 is threadedly engaged with the threaded groove 206 on the surface of the rotating shaft 205. Two supporting cavities 502 are opened on the left and right sides of the inner wall of the sliding mounting sleeve 501. Two connecting threaded sleeves 503 are vertically installed in each supporting cavity 502. Two sets of supporting threaded sleeves 504 are provided through all six sides of the outer wall of the sliding mounting sleeve 501 between the two connecting threaded sleeves 503. A sliding groove 505 is installed perpendicular to the bottom of the sliding mounting sleeve 501. Two sliders 506 are slidably arranged inside the sliding groove 505. A threaded connecting rod 507 is connected to the top of each slider 506.

[0046] Adjusting bolts 508 are rotatably installed inside the two connecting threaded sleeves 503 and the two sets of supporting threaded sleeves 504. The lower end of the adjusting bolts 508 inside the two connecting threaded sleeves 503 is connected to the threaded connecting rod 507. The adjusting bolts 508 inside the two sets of supporting threaded sleeves 504 all pass through one end face of the sliding mounting sleeve 501 and are fixedly connected to a trapezoidal block 509. Two supporting rotating shafts 510 are vertically installed inside the sliding mounting sleeve 501 on the opposite side of the two supporting cavities 502. An internal threaded sleeve 511 is installed in the middle of the two supporting rotating shafts 510.

[0047] Specifically, the sliding mounting sleeve 501 adopts an integral structure with a hexagonal outer wall and a circular inner hole. The internal threaded sleeve 511 is fixed by the support shaft 510 in its internal support cavity 502, allowing the internal threaded sleeve 511 to form a precise threaded fit with the threaded groove 206 on the surface of the rotating shaft 205 in the middle of the second set of transmission pulleys 204. This allows the sliding mounting sleeve 501 to move smoothly axially when the rotating shaft 205 rotates. The hexagonal outer wall structure provides a flat, vertical mounting surface for connecting the threaded sleeve 503 and supporting the threaded sleeve 504, ensuring the installation accuracy and stress stability of the adjusting bolt 508. It also increases the top bearing area, providing more stable support for the transformer box and avoiding slippage and positioning misalignment issues when using fixtures with a circular outer wall. By tightening the adjusting bolt 508 inside the supporting threaded sleeve 504, the trapezoidal block 509 can be pushed inward to clamp the transformer box, thus achieving rapid fixation of the tooling; by adjusting the adjusting bolt 508 inside the connecting threaded sleeve 503, the fitting clearance between the slider 506 and the slide groove 505 can be adjusted to ensure the smoothness of axial movement and the guiding accuracy, so that the transformer box can complete the uniform bundling and winding of the enameled wire during the axial movement with the sliding mounting sleeve 501, realizing the integrated operation of conveying and wire bundling.

[0048] As a further improvement to the above technical solution: the parallel stranding assembly 6 includes a mounting groove 601 installed in the middle of the upper surface of the mounting base 1. Two stationary plates 602 are connected to the inner wall of the mounting groove 601. A rotating shaft 603 is installed in the middle of the upper surface of the inner wall of the mounting groove 601. A vertical rotating column 604 is vertically installed in the middle of the rotating shaft 603. A rotating ring 606 is installed at the lower end of the outer ring surface of the vertical rotating column 604. Two rotating plates 607 are connected to the surface of the rotating ring 606. Two sets of vertically installed rotating rollers 608 are passed through the inner ends of the two stationary plates 602 away from the mounting groove 601 and the inner ends of the two rotating plates 607 away from the rotating ring 606. The surfaces of each pair of rotating rollers 608 are fixedly connected by a spring plate 609. A parallel stranding cylinder 610 is connected to the upper end of the vertical rotating column 604. Two transition rings 605 are connected to the front and rear ends of the parallel stranding cylinder 610. The inner wall of the parallel stranding cylinder 610 is made of ceramic material, which can reduce frictional heat generation during the parallel stranding process and improve the smoothness of parallel stranding.

[0049] The controller 7 is mounted on the right side surface of the mounting base 1. The controller 7 is a rectangular box structure and is fixed to the side wall of the mounting base 1 by bolts. It integrates a control unit and is electrically connected to the driver of the servo motor 210 through a control cable. The right ends of the three rotating shafts 205 all pass through the protective cover on the side of the protective frame 201, and the ends of the three rotating shafts 205 are all connected to locking sleeves 8.

[0050] Specifically, the mounting groove 601 is fixed to the middle of the upper surface of the mounting base 1, providing a stable mounting foundation for the entire stranding assembly 6. The rotating shaft 603 can rotate freely around its own axis without additional power drive. The vertical rotating column 604 and the rotating ring 606 swing synchronously with the rotating shaft 603, allowing the rotating plate 607 to deflect circumferentially relative to the stationary plate 602. Under the action of the conveying tension, the enameled wire passes through the rotating drum 608 and the stranding drum 610. When the transformer box moves axially back and forth with the sliding assembly 5, the enameled wire changes in a fan shape, and the direction of the tension changes synchronously. This causes the rotating plate 607 and the vertical rotating column 604 to adaptively deflect at the corresponding angle, avoiding the problems of right-angle hard bends and stress concentration in the enameled wire. Two adjacent rotating rollers 608 are elastically connected by spring plates 609. The elastic deformation of the spring plates 609 automatically adapts to the tension fluctuations when the multi-strand enameled wires are converged, and performs secondary integration and tightening of the pre-jointed enameled wires. When the transformer box returns or the tension decreases at the end of production, the rebound force of the spring plates 609 can drive the rotating plates 607 and the joining cylinder 610 to automatically reset, without manual adjustment or additional power drive. Through the joining cylinder 610 connected to the upper end of the vertical rotating column 604, the integrated and tightened multi-strand enameled wires are guided into the interior of the joining cylinder 610 through the transition rings 605 at both ends. Utilizing the smooth and wear-resistant properties of the ceramic material on the inner wall of the joining cylinder 610, the frictional resistance of the enameled wires during the joining process is greatly reduced, avoiding coil damage caused by frictional heat, thereby ensuring the smoothness of the joining process and the stability of the winding quality. The protective cover serves to isolate and protect the equipment from foreign objects entering the transmission area; the locking sleeve 8 is used to lock the rotating shaft 205 when the equipment is stopped or under maintenance to prevent accidental rotation and ensure operational safety.

[0051] Working principle: The operator first prepares before starting the machine, and checks the installation and tightness of each component on the mounting base 1. Unlike traditional winding equipment that requires calibration of the synchronization parameters of multiple motors, this device only needs to confirm that the transmission component 2 and the parallel strand component 6 are not loose. Then, the power supply of the controller 7 is turned on, and the process parameters for winding production are entered on the operation interface of the controller 7 to quickly complete the production preparation.

[0052] After setting the parameters, the operator loads the materials, fitting various enameled wire reels of different specifications onto the surface of the primary drive roller 310 of the primary conveying component 3. The fixing bolts 311 are then tightened to secure the reels. Unlike traditional equipment that can only produce a single specification, this device can install multiple sets of reels of different specifications simultaneously. The transformer box to be bundled is then placed onto the surface of the sliding mounting sleeve 501 of the following sliding component 5. The hexagonal adjusting bolts 508 inside the supporting threaded sleeve 504 are then tightened in sequence, causing the trapezoidal block 509 to move inward and press against the transformer box, thus completing the clamping and fixing of the transformer box.

[0053] After the material is fed, the operator threading the wires is performed. The enameled wire ends from each material tray are passed around the back of the secondary transmission roller 404 of the secondary conveying component 4, and then converged and passed through the stranding component 6. The wire ends enter the stranding cylinder 610 through the transition ring 605, and the final end is fixed to the terminal of the transformer box. Compared with the complicated operation of traditional equipment that requires tension adjustment of each strand, this device can complete the threading and material feeding in one go.

[0054] After the wiring is completed, the operator presses the start button on the controller 7, and the servo motor 210 starts to run. Unlike traditional equipment that requires multiple motors to drive each mechanism separately in a complex transmission, this device adopts a single power source design. The servo motor 210 is horizontally installed on the outside of the left protective frame 201. Its output shaft drives the drive pulley 202 to rotate. Through the two annular grooves 209 opened on the outer ring surface of the drive pulley 202, the first set of transmission belts 207 and the second set of transmission belts 208 are driven to rotate synchronously, so that the first set of transmission pulleys 203 and the second set of transmission pulleys 204 rotate synchronously at the same speed, realizing the strict synchronous operation of the three rotating shafts 205, fundamentally avoiding the synchronization error problem existing in traditional multi-motor drives.

[0055] During equipment operation, the rotating shaft 205 in the middle of the first set of transmission pulleys 203 drives the gear column 301 to rotate, causing the cylindrical gear sleeve 302 and the locking disc 303 to rotate synchronously. The reciprocating spring 305 and damping block 306 in the arc hole 304 on the surface of the locking disc 303 automatically absorb the vibration of operation. Compared with the traditional rigid transmission structure, the damping buffer structure of this device effectively reduces the operating noise, drives the pressure shaft 307 and T-shaped disc 309 to rotate smoothly, thereby making the first-stage transmission roller 310 rotate at a uniform speed, realizing the synchronous and stable conveying of multiple strands of enameled wire.

[0056] After the enameled wire is conveyed down from the primary drive roller 310, it is stranded and wound around to the rear side of each secondary drive roller 404 of the secondary conveying assembly 4. The rotating shaft 205 in the middle of the drive pulley 202 drives the cylindrical mounting sleeve 401 to rotate. The spring damping rod 403 in the telescopic groove 402 automatically pushes the lifting plate 406 to extend outward, so that the lifting plate 406 is in close contact with the square slot 405 on the inner wall of the secondary drive roller 404, causing the secondary drive roller 404 to rotate adaptively. Unlike the limitations of the fixed diameter drive roller in traditional equipment, this floating structure can adapt to enameled wires of different diameters. The multiple strands of enameled wire converge at the rear side of the secondary drive roller 404 to complete the first pre-coupling and sorting.

[0057] Meanwhile, the threaded groove 206 on the surface of the rotating shaft 205 in the middle of the second set of transmission pulleys 204 forms a precise threaded engagement with the internal threaded sleeve 511 on the internal support shaft 510 of the sliding mounting sleeve 501, so that the following sliding component 5 moves slowly along the axial direction of the rotating shaft 205. The groove 505 and the slider 506 provide smooth guidance, thereby driving the clamped and fixed transformer box to move axially at a uniform speed, realizing the uniform and orderly bundling and winding of the enameled wire on the transformer box. Compared with the complex design of traditional equipment that requires a separate wire laying mechanism, this device highly integrates the functions of conveying, bundling and stranding.

[0058] After pre-stranding, the enameled wires continuously enter the stranding assembly 6. The mounting groove 601 provides stable support. During the axial movement of the transformer box, the enameled wires change in a fan shape, and the tension direction changes synchronously. This causes the rotating shaft 603 and the vertical rotating column 604 to adaptively deflect. The rotating roller 608 and the spring plate 609 adaptively tension the enameled wires, performing secondary integration and tightening of the multiple strands. Then, through the smooth guidance of the ceramic inner wall of the stranding cylinder 610, the final precision stranding operation is completed. During the production return trip, the spring plate 609 can drive the stranding assembly to automatically reset. Unlike traditional equipment with fixed stranding guidance, which is prone to hard bending and sudden tension changes, this adaptive structure has a flexible transition throughout the entire process, effectively reducing friction and improving winding quality.

[0059] After production is completed, the operator presses the stop button on the controller 7, and the servo motor 210 stops running. The three rotating shafts 205 can be axially locked and positioned by the locking sleeve 8. When it is necessary to change product specifications or perform equipment maintenance, the operator can release the locking sleeve 8 to pull out the rotating shafts 205 and quickly replace the transmission rollers and transformer boxes at each stage. The open structure of the protective frame 201 facilitates the operator's maintenance work. Compared with the difficulty of disassembly and maintenance of traditional equipment, this quick-release structure greatly reduces maintenance time and cost.
