Description

Technical Field

[0001] This invention belongs to the technical field of transformer foil winding equipment, specifically relating to an automatic insulation supply device for foil winding machines. Background Technology

[0002] In the transformer foil winding process, insulating paper / film needs to be wound between copper and aluminum foil layers. The uniform and continuous supply of the insulation layer directly determines the insulation performance and production efficiency of the transformer winding. Traditional foil winding machines are equipped with insulation supply equipment that only has a single-station unwinding structure, coupled with a fixed cutter for manual cutting of the insulation material. This can basically complete the unwinding and segmented cutting of the insulation roll, meeting the low-capacity processing needs of small transformers.

[0003] However, existing equipment has obvious defects in large-scale continuous production: First, after the single unwinding roll is exhausted, the whole machine must be stopped to replace the roll, which will significantly interrupt the continuity of the production line and reduce the overall processing efficiency; Second, ordinary fixed cutters cannot flexibly adjust the cutting height and lateral cutting stroke according to the winding specifications, resulting in poor cutting dimensional accuracy and inconsistent insulation layer length, which can easily cause transformer insulation defects; Third, the unwinding roller and drive shaft rely only on simple sleeve connection, which makes it easy to slip during the feeding process, cause axial displacement of the roll, and result in poor coordination stability between the cutting and winding processes.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention features an automatic repositioning mechanism for the unwinding roller that operates without stopping the machine. The mechanism includes a dual-station mounting rod and a gear-driven repositioning transmission assembly. When the remaining material roll is insufficient, the motor's three-drive gear set rotates the mounting box along a semi-circular slide rail for repositioning. The spare roll can be directly switched to the feeding station without requiring the entire machine to stop for material roll replacement, effectively eliminating downtime and significantly improving the continuous processing efficiency of the foil winding production line. Simultaneously, the mounting rod is equipped with a strip-shaped protrusion and a pressure plate locking structure, which bidirectionally limits the unwinding roller body in both the circumferential and axial directions, preventing feeding slippage and roll movement, resulting in more stable feeding operation.

[0018] 2. This invention adds a series of supporting limiting and guiding structures, such as strip-shaped protrusions, strip-shaped grooves, pressure plates, fastening screws, T-shaped sliders, and semi-circular slide rails, to the unwinding roller body and the mounting rod mating position. The repositioning process relies on the T-shaped sliders and slide rails to constrain the movement trajectory, resulting in smooth rotation and repositioning without shaking. The assembly and disassembly of the material roll can be completed simply by removing and installing the fastening screws, making the material roll replacement operation convenient and reducing the difficulty of equipment operation and maintenance.

[0019] 3. This invention incorporates a cutting mechanism equipped with a vertical lifting screw module and a horizontal feed screw module. The laser cutting blade allows for free adjustment of the cutting height and horizontal cutting stroke, adapting to insulation rolls of different widths and thicknesses, as well as transformer windings of various specifications. The laser non-contact cutting method produces smooth, burr-free cuts. Combined with limit blocks and limit slots, it achieves overtravel protection during lifting, ensuring high cutting dimensional accuracy and reducing winding quality defects caused by poor insulation layer cutting.

[0026] 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.

[0027] Please see Figure 1-5The present invention provides the following technical solution: an automatic insulation supply device for a foil winding machine, comprising a base plate 1, which is horizontally arranged as the base for the entire machine and provides installation support for all other components; side plates 6 are vertically fixed on the left and right sides of the upper end of the base plate 1, and the side plates 6 are symmetrically and parallelly arranged, serving to limit movement on both sides and support various moving mechanisms; a mounting plate 8 is installed on the lower side of the side plate 6, which is horizontally attached to the upper surface of the base plate 1, increasing the contact area between the side plate 6 and the base plate 1 and improving the installation stability of the side plate; the mounting plate 8 and the base plate 1 are locked and fixedly connected by multiple sets of bolts 7, realizing detachable assembly and facilitating subsequent disassembly and maintenance; the upper rear side of the side plate 6 A motor 5 is mounted at the corner and is horizontally fixed to the outer wall of the side plate 6 to provide rotational power for winding the roll material. A winding roller 4 is horizontally extended from the output end of the motor 5 and is rotatably positioned between the two sets of side plates 6 for winding and taking up the cut insulation material. An automatic unwinding roller switching mechanism 2 is installed at the side edge of the side plate 6 and to the left of the winding roller 4. This mechanism is responsible for placing the insulation material roll and can automatically switch the roll when the roll is used up without stopping the whole machine. A cutting mechanism 3 is installed at the center of the side edge of the side plate 6, in the area between the automatic unwinding roller switching mechanism 2 and the winding roller 4, for precisely cutting the insulation roll material to a fixed length during the conveying process.

[0028] See Figure 1-3 The unwinding roll non-stop automatic repositioning mechanism 2 includes a transmission assembly 29. The transmission assembly 29 is installed on the rear edge of the base plate 1 and behind the two sets of side plates 6. The transmission assembly 29 provides rotational driving force for the entire unwinding and repositioning action, realizing the switching of the material roll station. The transmission assembly 29 is horizontally connected to the mounting box 210 on the side facing the side plate 6. The mounting box 210 is suspended on the outside of the side plate 6 and serves as a protective and mounting carrier for the motor 211. Two sets of motor 211 are symmetrically installed on the left and right sides inside the mounting box 210, and the output shafts of the two sets of motor 211 face each other. The arrangement includes two independent mounting rods 28, which drive the two rolls of material simultaneously for standby. The output end of the second motor 211 is coaxially fixed with the mounting rod 28, which extends horizontally outward from the mounting box 210 and serves as the material roll bearing shaft. The outer surface of the mounting rod 28 is coaxially fitted with the unwinding roller body 25, which is used to hold the entire roll of insulating material. The shaft of the unwinding roller body 25 has a through hole 23 corresponding to the mounting rod 28. The mounting rod 28 passes through the through hole 23 to achieve the sleeve assembly of the unwinding roller body 25, ensuring the coaxial rotation and conveying of the material roll.

[0029] See Figure 1-3The unwinding roller automatic repositioning mechanism 2 also includes a strip-shaped protrusion 27. The outer wall of the mounting rod 28 is integrally machined with the strip-shaped protrusion 27, which serves as a circumferential transmission limit. The inner wall side of the through hole 23 is provided with a strip-shaped groove 24 corresponding to the strip-shaped protrusion 27. The strip-shaped protrusion 27 is inserted into the strip-shaped groove 24. During transmission, it drives the unwinding roller body 25 to rotate synchronously, preventing the unwinding roller body 25 from slipping relative to the mounting rod 28 and ensuring stable feeding speed.

[0030] See Figure 1-3 The unwinding roller automatic repositioning mechanism 2 also includes a pressure plate 22. The pressure plate 22 is installed at the outer end of the mounting rod 28 away from the mounting box 210. The pressure plate 22 fits against the outer end face of the unwinding roller body 25 to achieve axial limiting and prevent axial movement of the material roll during conveying. A fastening screw 21 is installed through the side of the pressure plate 22. The end side of the mounting rod 28 has a screw hole 26 corresponding to the fastening screw 21. The fastening screw 21 is screwed into the screw hole 26 to lock the pressure plate 22, quickly completing the axial fixation of the unwinding roller body 25 and making it convenient to disassemble and assemble the material roll.

[0031] See Figure 1-3 The automatic repositioning mechanism 2 for unwinding rolls without stopping also includes a T-shaped slider 212. The T-shaped slider 212 is provided on the bottom inner side of the mounting box 210 and above the base plate 1 to support the mounting box 210 to move synchronously with the transmission components. The side of the base plate 1 is provided with a semi-circular slide rail 213 corresponding to the T-shaped slider 212. The T-shaped slider 212 slides along the semi-circular slide rail 213 to guide and limit the movement trajectory of the mounting box 210, ensuring that the repositioning process is smooth and does not deviate.

[0032] See Figure 1-3 The transmission assembly 29 includes a second mounting box 291, which is installed at the rear edge of the side plate 6. The internal enclosure of the second mounting box 291 houses the gear transmission structure and provides dust protection. A third motor 294 is installed on the side of the second mounting box 291, which provides rotational power for material roll switching. A small gear 295 is located inside the second mounting box 291 at the output end of the third motor 294. The small gear 295 rotates synchronously with the third motor 294. A large gear 293 is meshed on the side of the small gear 295. The meshing of the large and small gears reduces speed and increases torque, improving the shifting load capacity. A rotating shaft 292 is installed on the side of the large gear 293 and is fixedly connected to the first mounting box 210. The rotation of the gear drives the rotating shaft 292 to rotate, thereby driving the first mounting box 210 to complete the material roll shifting action.

[0033] See Figure 1-3 The connection between the rotating shaft 292 and the side plate 6 is made by a bearing. The bearing reduces the rotational friction resistance of the rotating shaft 292, reduces wear, and ensures smooth rotation and lower noise.

[0034] See Figure 3-5 The cutting mechanism 3 includes a mounting base 35, which is vertically fixed at the center of the side of the base plate 1, serving as the base for the overall lifting and lowering movement of the cutting module. A motor 312 is mounted at the lower end of the mounting base 35, providing power for the overall lifting and lowering of the cutting blade. A screw 36 is provided at the output end of the motor 312, rotating in both forward and reverse directions with the motor 312. A nut slider 33 is threaded onto the surface of the screw 36, converting the rotational motion of the screw into the vertical linear displacement of the nut slider 33 via threaded transmission. A square groove 34 corresponding to the nut slider 33 is provided inside the mounting base 35, vertically guiding the nut slider 33 and preventing deviation during lifting and lowering. The nut slider 33 is fixedly mounted on the side of the mounting base 35. The device is equipped with a mounting base 2 313, which rises and falls synchronously with the nut slider 1 33 and carries a transverse cutting component. A motor 5 311 is installed on the side of the mounting base 2 313, which provides power for the transverse feed of the cutting blade. A screw 2 310 is provided at the output end of the motor 5 311, which is driven by the forward and reverse rotation of the motor 5 311. The surface of the screw 2 310 is threadedly connected to the nut slider 2 39, which converts the rotation of the screw into the transverse linear movement of the nut slider 2 39. The interior of the mounting base 2 313 has a square groove 2 31 corresponding to the nut slider 2 39, which limits and guides the transverse sliding of the nut slider 2 39. A laser cutting blade mounting component 32 is installed at the upper end of the nut slider 2 39, which completes the roll material cutting operation as the nut slider 2 39 moves laterally.

[0035] See Figure 3-5 The cutting mechanism 3 also includes a limiting block 38. The nut slider 33 is equipped with a limiting block 38 on its side to limit the lifting stroke of the cutting mechanism and prevent overtravel collision. The mounting base 35 has a limiting groove 37 corresponding to the limiting block 38 on its side. The limiting block 38 slides up and down inside the limiting groove 37. When it reaches both ends of the groove, it triggers the lifting limit to protect the equipment structure.

[0036] See Figure 3-5The laser cutting blade mounting assembly 32 includes a connecting plate 322. The upper end of the nut slider 39 is screwed onto the connecting plate 322, which serves as the upper mounting carrier for the laser cutting blade body 321. The upper end of the connecting plate 322 is fixedly mounted with the laser cutting blade body 321, which is the actuating component for cutting insulating rolls and achieves non-contact cutting using laser. The lower end of the nut slider 39 is screwed onto the connecting plate 324, which is used for wiring and fixing the wire ends. The output end of the laser cutting blade body 321 is provided with a wire 323 for transmitting laser power and control signals. The other end of the wire 323 is connected to a wire 325 to extend the line for easy connection to an external control power supply. The nut slider 39 has a circular hole 326 inside corresponding to the wire 323 for the wire 323 to pass through, keeping the line neat and preventing breakage due to movement.

[0037] See Figure 3-5 The nut slider 33 has a threaded mounting hole inside that corresponds to the screw 36. The threaded hole fits precisely with the screw 36 to achieve precise lifting and lowering transmission. The nut slider 39 has a threaded mounting hole inside that corresponds to the screw 310. It matches the screw 310 to ensure the positioning accuracy of the cutting blade's lateral movement.

[0038] The working principle and usage process of this invention are as follows: Before use, two rolls of insulating material are respectively mounted on the unwinding roller body 25 outside the two sets of mounting rods 28. The through hole 23 inside the unwinding roller body 25 is aligned with the strip protrusion 27 on the mounting rod 28 to complete circumferential positioning. Then, the pressure plate 22 is attached to the outer end face of the unwinding roller body 25, and the fastening screw 21 is tightened so that it is screwed into the screw hole 26 to complete the axial locking and fixing of the unwinding roller body 25. Subsequently, the end of the insulating material is pulled through the cutting mechanism 3 in sequence and finally fixed on the surface of the winding roller 4. The first wire 323 passes through the circular hole 326 inside the nut slider 39 and connects with the second wire 325 to connect the power supply of the whole machine.

[0039] When the equipment is working normally, motor 211 drives the mounting rod 28 to rotate at a constant speed, which drives the unwinding roller body 25 to rotate synchronously to release the insulating roll. Motor 5 drives the winding roller 4 to rotate continuously to wind up the insulation layer, and the roll is stably conveyed. When the system detects that the remaining amount of roll material on the current unwinding roller body 25 is insufficient, motor 3 294 starts, which drives the small gear 295 to mesh and drive the large gear 293 to rotate. The rotating shaft 292 synchronously drives the mounting box 210, which rotates along the semi-circular slide rail 213 of the base plate 1 to change position, and rotates the spare roll to the feeding station. The whole process does not require stopping the machine and realizes uninterrupted material supply.

[0040] When the foil winding machine needs a fixed length of insulation layer, motor 4 312 drives screw 1 36 to rotate, causing nut slider 1 33 to rise along square groove 1 34, and limit block 38 to slide synchronously along limit groove 37, raising laser cutting blade mounting assembly 32 to the roll material cutting height; then motor 5 311 drives screw 2 310 to rotate, causing nut slider 2 39 to move quickly laterally along square groove 2 31, and laser cutting blade body 321 emits laser to cut the insulation roll laterally; after cutting, motor 4 312 reverses to drive cutting mechanism 3 to descend and reset, motor 5 311 rotates in the opposite direction to make laser cutting blade mounting assembly 32 return to the initial position, and winding roller 4 continues to complete the winding operation of the cut insulation layer, completing the entire process of automatic insulation material supply, cutting, and winding in a cycle.

[0041] When the equipment needs to change the material roll, simply loosen the fastening screw 21, remove the pressure plate 22, and pull the empty unwinding roller body 25 out from the mounting rod 28. After reinstalling the new roll, tighten the pressure plate 22 to continue using it. All motors of the whole machine are connected to an external control system, which can automatically adjust the feeding speed, cutting length, and repositioning timing to meet the continuous production needs of foil winding machines.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
