Description

Technical Field

[0001] This invention belongs to the field of foil winding machine technology, specifically relating to a foil winding machine with easily adjustable foil tension. Background Technology

[0002] Foil winding machines are core specialized equipment for the production of transformer foil coils. They mainly complete the forming process of transformer coils by continuously conveying metal foils such as copper foil and aluminum foil, and simultaneously winding the insulation layer. The stability and adjustability of the foil conveying tension directly determine the flatness, density and product qualification rate of the coil winding.

The tensioning electric telescopic rod automatically drives the support plate and tension roller to rise and fall, forming a closed-loop adjustment. This avoids manual delays, ensures constant tension, and improves winding uniformity and density. The fixed roller and adjustable roller work together to press and straighten the foil, eliminating initial bending and slack, and providing a stable foil input for subsequent processes. The lifting electric telescopic rod drives the adjustable roller to rise and fall, allowing for flexible adjustment of the spacing according to the foil thickness, further enhancing the tension control accuracy and adaptability.

[0018] 2. This invention achieves real-time automatic detection and precise correction of foil position through the linkage of photoelectric correction sensors, correction motors, correction lead screws, and square sliders. This effectively prevents lateral offset, ensures neat coil edges, and significantly improves product qualification rate. Simultaneously, adjusting the motor drives the bidirectional trapezoidal lead screw to synchronously move two photoelectric correction sensors closer or further away. This allows for rapid adjustment of the detection spacing according to different foil widths, adapting to various specifications and greatly enhancing the equipment's versatility.

[0019] 3. The present invention enables quick assembly and disassembly of the photoelectric correction sensor through the connecting component, which facilitates the disassembly, maintenance or replacement of the photoelectric correction sensor. The operation is simple; the photoelectric correction sensor can be removed by simply pulling it outward. Attached Figure Description

[0037] Please see Figure 6 The automatic tensioning assembly 5 includes a support frame 51, which is fixedly connected to the top of the foil winding machine body 1. One end of the support frame 51 is fixedly connected to a tensioning electric telescopic rod 52. A support plate 53 is fixedly connected above the tensioning electric telescopic rod 52. Tension sensors 54 are symmetrically and fixedly connected above the support plate 53. A tensioning seat 55 is fixedly connected above the tension sensors 54.

A fixed roller 59 is provided, and an adjustable roller 50 is provided above the fixed roller 59. The adjustable roller 50 is slidably connected to the lifting assembly 6 and the support frame 51. The tension is monitored by the tension sensor 54. When the tension is too large, the tensioning electric telescopic rod 52 drives the tensioning roller 56 to move down. When the tension is insufficient, the tensioning electric telescopic rod 52 drives the tensioning roller 56 to move up to tighten. The fixed roller 59 and the adjustable roller 50 work together to facilitate horizontal positioning, pressing and correction of the foil, eliminate the initial bending and slack state of the foil, and ensure the accuracy of subsequent tension monitoring.

[0038] Please see Figure 6The two sides of the support plate 53 are symmetrically and fixedly connected to the limiting sliders 57. The limiting sliders 57 and the support frame 51 are fitted and slidably connected. The middle of the limiting sliders 57 is slidably connected to the limiting rod 58. The two ends of the limiting rod 58 are fixedly connected to the support frame 51. The limiting sliders 57 slide along the limiting rod 58, which facilitates the stable lifting and lowering of the support plate 53 and the tension roller 56 above it.

[0039] Please see Figure 7 The lifting assembly 6 includes a lifting electric telescopic rod 61, which facilitates the adjustment of the distance between the adjustable roller 50 and the fixed roller 59 according to the thickness of the foil. The lifting electric telescopic rod 61 is symmetrically and fixedly connected to one end of the support frame 51. A lifting slider 62 is fixedly connected below the lifting electric telescopic rod 61. The adjustable roller 50 and the lifting slider 62 are rotatably connected by bearings. The lifting slider 62 and the support frame 51 are in close contact and slidably connected. The two ends above the lifting slider 62 are symmetrically and fixedly provided with lifting slide rods 63. The lifting slide rods 63 are in close contact and slidably connected to the support frame 51. A stop block 64 is fixedly connected above the lifting slide rod 63, which facilitates the stable lifting and lowering of the lifting slider 62.

[0040] The working principle and usage process of this invention: The foil material passes through the correction component 4 and the automatic tensioning component 5 in sequence, and enters the winding process after completing the position correction and tension adjustment. When the foil material enters the area of ​​the automatic tensioning component 5, the tension sensor 54 monitors the tension value at the tensioning roller 56 in real time. When the tension is insufficient, the tensioning electric telescopic rod 52 drives the support plate 53 to rise. The limiting sliders 57 on both sides of the support plate 53 slide along the limiting sliders 58 to ensure smooth lifting and lowering. The support plate 53 drives the tensioning seat 55 and the tensioning roller 56 to move upward, increasing the tension force. When the tension is too high, the tensioning electric telescopic rod 52 drives the tensioning roller 56 to move downward, reducing the tension force, thereby realizing closed-loop automatic tension adjustment. Simultaneously, the fixed roller 59, in conjunction with the adjustable roller 50 above, horizontally limits and presses the foil, eliminating its initial bending and slack. The lifting electric telescopic rod 61 in the lifting assembly 6 drives the lifting slider 62 to slide along the lifting slide bar 63, raising and lowering the adjustable roller 50. The distance between the adjustable roller 50 and the fixed roller 59 is adjusted according to the foil thickness. The stop block 64 prevents the lifting slide bar 63 from dislodging, ensuring the pressing effect. Subsequently, the foil enters the area of ​​the correction assembly 4. The photoelectric correction sensor 49, located above the adjustment assembly 48, detects the edge position of the foil in real time. When a deviation is detected, the control system issues a command, the correction motor 42 starts, and drives the correction screw 43 to rotate. The correction screw 43 drives the square slider 44 to slide smoothly along the guide slide bar 47 within the correction drive seat 41. The correction roller seat 45 above the square slider 44 moves accordingly, thereby driving the correction roller 46 to move laterally, correcting the foil to the correct position and achieving automatic correction. This is useful during equipment debugging or maintenance. When changing foil specifications, the spacing between the two photoelectric correction sensors 49 can be adjusted by adjusting component 48: adjusting motor 482 drives bidirectional trapezoidal lead screw 483 to rotate, and a limit block 487 is fixed in the middle of the bidirectional trapezoidal lead screw 483. Its two reverse threads drive two adjusting sliders 484 to move towards or away from each other along the guide slider 488 in the guide groove of adjusting seat 481. The adjusting slider 484 drives the two photoelectric correction sensors 49 to move closer or further away synchronously through connecting block 485 and support rod 486 to adapt to foils of different widths. When it is necessary to disassemble or replace the photoelectric correction sensor 49, simply pull the cylindrical insert 402 below it out of the connector 401. The positive magnetic block 405 below the cylindrical insert 402 will disengage from the negative magnetic block 406 in the connector 401, and the rubber fastening sleeve 403 will exit from the insertion hole of the adjusting seat 481. The guide port 404 facilitates insertion and removal, enabling quick assembly and disassembly. During installation, insert the cylindrical insert 402 into the connector 401. The positive magnetic block 405 and the negative magnetic block 406 are magnetically attracted and fixed, and the rubber fastening sleeve 403 ensures a tight connection. The entire process is controlled by the electrical control box 2 and the controller 3, achieving fully automatic operation.
