Description

Technical Field

[0001] This invention relates to the field of welding wire feeding technology, and more particularly to a wire feeding device for thick plate welding equipment, belonging to the field of welding tooling technology. Background Technology

[0002] In welding operations, a heat source locally heats the base material to melt and form a molten pool. The wire feeding mechanism needs to feed the welding wire into the molten pool at a specific speed, and the melting speed of the welding wire and the wire feeding speed need to be precisely matched to ensure the stability of the molten pool volume and the formation of the weld. In the welding of thick plates such as automobile chassis, in order to reduce the waiting time caused by the cooling of the molten pool in single-wire welding, the double-wire welding method has emerged. However, the early wire feeding mechanism of double-wire welding has obvious limitations. The two welding wires are fed by independent conveyor wheel assemblies. Although they can be fed to the welding gun head synchronously and in parallel, there is a dispersion gap between the welding wires, which leads to arc dispersion and heat source inability to concentrate. This seriously affects the penetration of the welding wire, resulting in problems such as insufficient penetration depth and poor weld formation, which makes it difficult to meet the quality requirements of thick plate welding. In related technologies, two welding wires are often wound and fed using a combination of a rotating rod, support frame, and hot-pressing confluence mechanism. This "twisting" effect concentrates arc energy, playing a role in improving penetration and welding speed, and reducing defects such as porosity and cracks. However, this device still has significant drawbacks in practical applications. As a key component for supplying welding wire, the wire winding shaft cannot be quickly disassembled after the wire on its outer surface is depleted. This results in operators spending considerable time replenishing the wire supply, causing welding interruptions and severely impacting the continuity and efficiency of wire-fed welding. The shortcomings of existing technologies also lie in their overall adaptability. Neither the early independent conveyor wheel assembly dual-wire feeding mechanism nor the winding and feeding device can simultaneously guarantee welding quality and operational efficiency. Early devices suffered from arc dispersion, which affected welding results. While the wire feeding device improved penetration and weld quality, the inconvenience of disassembling and assembling the wire winding shaft led to excessively long downtime, making it difficult to meet the demands of continuous and efficient modern welding production. These shortcomings mean that there is still considerable room for improvement in existing wire feeding devices for thick plate welding scenarios. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a wire feeding device for a thick plate welding equipment, in order to address the deficiencies of the existing technology and solve the problems mentioned in the background art.

[0004] To solve this technical problem, the present invention provides a wire feeding device for a thick plate welding equipment, comprising a housing, an outer cover, a wire feeding mechanism, a mounting base, a drive motor, and a closing mechanism. The outer cover is installed at one end of the housing, and the closing mechanism is movably installed on the outside of the housing. The wire feeding mechanism is located inside the housing, and the mounting base is fixed at the other end of the housing. The drive motor is fixed on the mounting base, and its output end passes through the mounting base and the housing and is connected to the wire feeding mechanism to drive it. The wire feeding mechanism includes a transmission module, a mounting module, a wire feeding take-up roller, a wire supply, and a straightening module. The transmission module includes a gear ring, a turntable, and a cross plate. The outside of the turntable is connected to the drive motor, and the other side is connected to the cross plate. Two sets of mounting modules are fixedly installed at both ends of the cross plate. The mounting module is equipped with gears that mesh with the gear ring of the transmission module. The wire feeding take-up roller is mounted on the mounting module, and the wire supply is wound around its outer surface. A straightening module is installed in the middle of the outer side of the transmission module. The end of the wire supply passes through the straightening module and through the housing.

[0005] The turntable of the transmission module is rotatably connected to the middle of the side of the housing near the drive motor, and the output end of the drive motor is fixedly connected to the outer side of the turntable; the gear ring is fixedly installed on the edge of the housing near the drive motor.

[0006] The mounting module also includes a concave frame, a limiting bracket, a mounting rail, and mounting blocks. The gear is rotatably connected to both ends of the horizontal plate away from the drive motor. The concave frame is fixed to the side of the gear away from the drive motor. The inner ends of the concave frame are fixed with limiting brackets. The inner ends of the concave frame away from the drive motor are rotatably connected with mounting rails. Mounting blocks are slidably connected inside the mounting rails. The yarn feeding and take-up roller is fixedly disposed between two mounting blocks. The limiting bracket and the mounting blocks are snap-fitted together.

[0007] The limiting clamp assembly includes a side rail, a slot, a limiting spring, a slider, a locking block, and a synchronous adjustment handle. The slot is opened on the side of the mounting block near the horizontal plate. The side rail is fixedly installed at both ends inside the concave frame. The limiting spring is fixedly connected inside the side rail. The slider is fixedly connected to the end of the limiting spring. The locking block is fixedly installed on the outside of the slider. The end of the locking block passes through the side rail and the mounting rail and is inserted into the slot.

[0008] A synchronous adjustment handrail is fixedly installed on the outer side of the slider, and an anti-slip handrail is fixedly connected to the middle of the outer side of the synchronous adjustment handrail. The two sliders are connected to each other through the synchronous adjustment handrail.

[0009] The correction module includes a support rod, a correction plate, correction guide holes, a connecting arm, and a correction sleeve. One end of the support rod is fixed to the middle of the side of the horizontal plate away from the drive motor, and the other end of the support rod is fitted with a correction plate. Correction guide holes are provided at both ends of the correction plate. A connecting arm is fixedly installed on the top of the correction plate, and a correction sleeve is fixedly installed on the outer end of the connecting arm. The end of the supply wire passes through the correction guide holes and penetrates the correction sleeve and the housing.

[0010] The closure mechanism includes a pre-removed slot, a limiting group, and a cover plate. The pre-removed slot is located in the center of the front of the housing. The limiting group is fixedly installed on one side of the outer surface of the housing. The cover plate covers the outer surface of the pre-removed slot.

[0011] The limiting assembly includes an arc-shaped rail, a sliding block, a limiting hole, a limiting arm, and a limiting screw. The arc-shaped rail is fixedly installed on the outer surface of the housing at the end away from the drive motor. The sliding block is slidably connected inside the arc-shaped rail. A cover plate is fixedly installed on the side of the sliding block near the drive motor. The cover plate covers the outside of the pre-reserved slot for disassembly and assembly. A limiting arm is fixedly installed on the outside of the cover plate near the end of the arc-shaped rail. A limiting screw is threaded to the outer end of the limiting arm. The end of the limiting screw passes through the limiting arm.

[0012] The limiting screw is a handle-type screw, and the outer side of the arc-shaped rail has limiting holes at equal intervals along the rail, with the end of the limiting screw inserted into the limiting hole.

[0013] The end of the housing away from the drive motor is provided with a hot-pressing manifold mechanism, and the end of the supply wire extends through the correction module and into the inner side of the hot-pressing manifold mechanism, with its outermost end penetrating the housing.

[0014] Beneficial Effects: During application, the arc-shaped rail, sliding block, and cover plate of the enclosed mechanism work together to provide a convenient operating opening. The synchronous adjustment handle of the installation module drives the slider to slide, and the tension limit spring causes the locking block to disengage from the slot, enabling quick assembly and disassembly of the wire feeding and take-up rollers. This allows for rapid replacement of the wire feeding and take-up rollers during use, reducing replacement time and thus improving work continuity and reducing the impact of wire feeding interruptions. It solves the problem in the prior art where the wire winding shaft cannot be quickly assembled and disassembled, leading to time-consuming replacement after wire feeding and affecting welding efficiency. The drive motor of this invention drives the turntable to rotate, causing the gear to roll along the gear ring. The wire feeding and take-up rollers revolve around the center and rotate on their own axis simultaneously. Combined with the hot-press confluence mechanism, the wire feed is converged, allowing the two wire feed strands to form a tightly wound "twisted" connection during use. This invention achieves the effect of concentrating arc energy and improving wire penetration in dual-wire welding, solving the problems of arc dispersion, insufficient penetration, and poor weld formation caused by wire dispersion in existing technologies. The correction guide hole and correction sleeve of the correction module of this invention provide multiple guidance for the supply wire, and the drive motor adjusts the speed to control the wire supply speed, ensuring stable wire supply during use and adapting to different welding needs. This improves welding accuracy and adapts to diverse welding scenarios, solving the problems of easy wire deviation and inflexible wire supply speed adjustment in existing technologies, which affect welding quality and adaptability.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] like Figures 1-8As shown, the present invention provides a wire feeding device for a thick plate welding equipment, including a housing 1, an outer cover 2, a wire feeding mechanism 3, a mounting base 4, a drive motor 5, and a closing mechanism 6. The outer cover 2 is installed at one end of the housing 1, and the closing mechanism 6 is movably installed on the outside of the housing 1. The wire feeding mechanism 3 is disposed inside the housing 1, and the mounting base 4 is fixed at the other end of the housing 1 (the end away from the outer cover 2). The drive motor 5 is fixed on the outside of the mounting base 4, and the output end of the drive motor 5 passes through the mounting base 4 and the housing 1 and is connected to the wire feeding mechanism 3 to drive the wire feeding mechanism 3. The wire feeding mechanism 3 includes a transmission module 31, a mounting module 32, a wire feeding and take-up roller 33, a wire feeding mechanism 34, and a straightening module 35. The transmission module 31 includes teeth. The system comprises a ring 311, a turntable 312, and a horizontal plate 313. The outer side of the turntable 312 is connected to the drive motor 5, and the other side (the side away from the drive motor 5) is fixedly connected to the horizontal plate 313. Two sets of mounting modules 32 are fixedly mounted on both ends of the horizontal plate 313. Each mounting module 32 is equipped with a gear 321, which meshes with the gear ring 311 of the transmission module 31. Mounting modules 32 are fixedly mounted on both ends of the transmission module 31 on the side away from the drive motor 5. The yarn feeding and take-up roller 33 is mounted on the mounting module 32, and a yarn feeding 34 is wound around the outer surface of the yarn feeding and take-up roller 33. A straightening module 35 is mounted on the middle of the outer side of the horizontal plate 313 of the transmission module 31. The end of the yarn feeding 34 passes through the straightening module 35 and penetrates the housing 1. When the present invention is in operation, the housing 1 forms a stable structure through the outer cover 2 and the mounting base 4. The drive motor 5 on the mounting base 4 provides power to the wire feeding mechanism 3. The output end of the drive motor 5 is connected to the transmission module 31 of the wire feeding mechanism 3, which drives the transmission module 31 to operate. The sealing mechanism 6 on the outside of the housing 1 can be opened when needed to facilitate operations such as replacing the wire feeding and winding roller 33.

[0019] The turntable 312 of the transmission module 31 is rotatably connected to the middle part of the side of the housing 1 near the drive motor 5, and the output end of the drive motor 5 is fixedly connected to the outer side of the turntable 312; the gear ring 311 is fixedly installed on the edge of the side of the housing 1 near the drive motor 5.

[0020] During operation, the transmission module 31 drives the wire feeding and take-up roller 33 to move, achieving stable feeding of the wire 34. The correction module 35 guides and corrects the wire feeding 34, reducing deviation during feeding, ensuring stable feeding path of the wire feeding 34, and improving wire feeding accuracy. The drive motor 5 can control the wire feeding speed by adjusting the rotation speed to adapt to different welding requirements. The setting of the closed mechanism 6 makes it easy to replace the wire feeding and take-up roller 33, reducing operation interruption time, thereby improving overall welding efficiency and solving the problems of unstable wire feeding and inconvenient replacement in the existing technology.

[0021] The mounting module 32 further includes a concave frame 322, a limiting bracket 323, a mounting rail 324, and a mounting block 325. The gear 321 is rotatably connected to both ends of the horizontal plate 313 away from the drive motor 5. The concave frame 322 is fixed on the side of the gear 321 away from the drive motor 5. The limiting bracket 323 is fixed to both ends of the inner side of the concave frame 322. The mounting rail 324 is rotatably connected to both ends of the concave frame 322 away from the drive motor 5. The mounting block 325 is slidably connected inside the mounting rail 324. The yarn feeding and take-up roller 33 is fixedly disposed between the two mounting blocks 325. The limiting bracket 323 and the mounting block 325 are snapped together.

[0022] During operation, the transmission module 31 operates under the drive of the drive motor 5. The output of the drive motor 5 causes the turntable 312 to rotate inside the housing 1. The horizontal plate 313 moves synchronously with the turntable 312. Since the gear ring 311 is fixed to the inner edge of the housing 1, the gear 321 of the mounting module 32 meshes with the gear ring 311. When the gear 321 moves with the horizontal plate 313, it rotates, thereby driving the concave frame 322 and the components mounted on it to move synchronously. The wire feeding and take-up roller 33 is mounted in the mounting rail 324 through the mounting block 325. The limit locking group 323 forms a locking and fixing with the mounting block 325 to ensure that the position of the wire feeding and take-up roller 33 is stable during the movement. When the feed wire 34 needs to be fed, the rotation of the gear 321 causes the feed wire take-up roller 33 to release the feed wire 34. At the same time, the rotation of the horizontal plate 313 causes the two feed wire take-up rollers 33 to move around the center of the turntable 312, so that the feed wire 34 forms an orderly winding state during the feeding process. This movement mode not only ensures the continuity and stability of the feed wire 34, but also achieves precise control of the feed wire speed through the meshing transmission of the gear 321 and the gear ring 311. With the fixed fixation of the feed wire take-up roller 33 by the limit card group 323, the shaking and deviation during the feed wire process are reduced, the feed wire accuracy is improved, and thus provides a reliable guarantee for the quality of subsequent welding operations. It effectively solves the problems of unstable feed wire and deviation of the conveying path in the prior art.

[0023] The limiting block 323 includes a side rail 3231, a slot 3232, a limiting spring 3233, a slider 3234, a locking block 3235, and a synchronous adjustment handle 3236. The slot 3232 is opened on the side of the mounting block 325 near the horizontal plate 313. The side rail 3231 is fixedly installed at both ends inside the concave frame 322. The limiting spring 3233 is fixedly connected inside the side rail 3231. The slider 3234 is fixedly connected to the end of the limiting spring 3233. The locking block 3235 is fixedly installed on the outside of the slider 3234. The end of the locking block 3235 passes through the side rail 3231 and the mounting rail 324 and is inserted into the slot 3232.

[0024] A synchronous adjustment handrail 3236 is fixedly installed on the outer side of the slider 3234. An anti-slip handrail is fixedly connected to the middle of the outer side of the synchronous adjustment handrail 3236. The two sliders 3234 are connected to each other through the synchronous adjustment handrail 3236.

[0025] During operation, the limiting clamp group 323 plays a crucial role in the installation and replacement of the feed take-up roller 33. When the feed take-up roller 33 needs to be installed, the operator holds the anti-slip grip on the outside of the synchronous adjustment handle 3236 and pulls it outward, causing the two sliders 3234 to slide along the side rail 3231. At this time, the limiting spring 3233 inside the side rail 3231 is stretched, and the locking block 3235 on the outside of the slider 3234 retracts from the mounting rail 324, releasing the restriction on the mounting block 325. After pushing the mounting block 325 together with the feed take-up roller 33 into the designated position along the mounting rail 324, the synchronous adjustment handle 3236 is released, and the limiting spring 3233 resets under its own elastic force, pushing the slider 3234 back, so that the locking block 3235 passes through the side rail 3231 and the mounting rail 324 and is precisely inserted into the locking groove 3232 on the mounting block 325, thus completing the fixation of the feed take-up roller 33. During the wire feeding process, the tight engagement between the locking block 3235 and the slot 3232 effectively prevents the mounting block 325 from sliding within the mounting rail 324, ensuring that the wire feeding take-up roller 33 remains stable as it moves with the mounting module 32. This avoids the wire feeding 34 from shifting due to the shaking of the wire feeding take-up roller 33. The synchronous adjustment of the handle 3236 ensures that the movements of the two sliders 3234 are synchronized, guaranteeing that the locking blocks 3235 on both sides simultaneously disengage from or engage with the slot 3232. This simplifies the operation process, shortens the replacement time of the wire feeding take-up roller 33, improves work efficiency, and solves the problems of unstable fixing and inconvenient replacement of the wire feeding take-up roller 33 in the prior art.

[0026] The correction module 35 includes a support rod 351, a correction plate 352, a correction guide hole 353, a connecting arm 354, and a correction sleeve 355. One end of the support rod 351 is fixed to the middle of the side of the horizontal plate 313 away from the drive motor 5. The other end of the support rod 351 (the end away from the drive motor 5) is equipped with the correction plate 352. Both ends of the correction plate 352 are provided with correction guide holes 353. The top of the correction plate 352 is fixedly installed with the connecting arm 354. The outer end of the connecting arm 354 is fixedly installed with the correction sleeve 355. The end of the supply wire 34 passes through the correction guide hole 353, through the correction sleeve 355, and through the housing 1.

[0027] The straightening module 35 plays a guiding and correcting role during the feeding of the feed yarn 34. The feed yarn 34 released by the feed take-up roller 33 first passes through the straightening guide holes 353 at both ends of the straightening plate 352. The support rod 351 stably fixes the straightening plate 352 on the horizontal plate 313, ensuring that the straightening plate 352 will not shake due to the operation of the equipment during the feeding process. The straightening guide holes 353 provide initial constraint on the feed yarn 34, preventing the feed yarn 34 from shifting laterally in the early stage of feeding, and keeping the feed yarn 34 on a relatively stable feeding trajectory. Subsequently, the feed yarn 34 continues to be fed forward and passes through the straightening sleeve 355 at the outer end of the connecting arm 354. The connecting arm 354 fixes the straightening sleeve 355 in a suitable position, forming a double guiding structure with the straightening plate 352. The straightening sleeve 355 further limits the feed yarn 34, correcting any slight deviation that may occur during the feeding process, and ensuring that the feed yarn 34 enters the subsequent hot pressing and converging mechanism with a precise posture. Throughout the wire feeding process, the synergistic effect of the straightening guide hole 353 and the straightening sleeve 355 effectively reduces the swaying of the supply wire 34 caused by its own toughness or equipment vibration, ensuring the consistency of the supply wire 34's feeding path. This ensures that the supply wire 34 is accurately positioned when entering the hot-pressing manifold, facilitating the formation of a stable "twisted" state. This dual straightening structure improves the stability and accuracy of the supply wire 34's feeding, avoiding arc dispersion or welding deviation caused by the supply wire 34's offset, thereby improving the weld formation quality and solving the problem of easy offset of the supply wire 34 in the prior art, which affects the welding effect. At the same time, the stable support of the support rod 351 and the connecting arm 354 ensures that the straightening module 35 is not easily deformed during long-term use, maintaining the stability of the straightening effect and extending the service life of the device.

[0028] The closing mechanism 6 includes a disassembly and assembly reserved slot 61, a limiting group 62, and a cover plate 63. The disassembly and assembly reserved slot 61 is opened in the middle of the front of the housing 1, the limiting group 62 is fixedly installed on one side of the outer surface of the housing 1, and the cover plate 63 covers the outer surface of the disassembly and assembly reserved slot 61.

[0029] The limiting assembly 62 includes an arc-shaped rail 621, a sliding block 622, a limiting hole 623, a limiting arm 624, and a limiting screw 625. The arc-shaped rail 621 is fixedly installed on the outer surface of the housing 1 at the end away from the drive motor 5. The sliding block 622 is slidably connected inside the arc-shaped rail 621. A cover plate 63 is fixedly installed on the side of the sliding block 622 near the drive motor 5. The cover plate 63 covers the outside of the disassembly and assembly reserved slot 61. A limiting arm 624 is fixedly installed on the outside of the cover plate 63 near the end of the arc-shaped rail 621. The outer end of the limiting arm 624 is threadedly connected to the limiting screw 625. The end of the limiting screw 625 passes through the limiting arm 624.

[0030] The limiting screw 625 is a handle-type screw, and the outer side of the arc-shaped rail 621 has equal-spaced limiting holes 623, with the end of the limiting screw 625 inserted into the limiting hole 623.

[0031] The closing mechanism 6 controls the opening and closing of the front of the housing 1 through the cooperation of the pre-reserved slot 61 and the limiting group 62. When the internal yarn feeding and take-up roller 33 needs to be replaced or maintained, the operator rotates the handle-type limiting screw 625 of the limiting group 62, causing its end to exit from the limiting hole 623 of the arc-shaped rail 621, releasing the fixation of the cover plate 63. Then, the operator pushes the cover plate 63, causing the sliding block 622 to slide along the arc-shaped rail 621, so that the cover plate 63 moves away from the outside of the pre-reserved slot 61, exposing the slot for operation. After the operation is completed, the operator pushes the cover plate 63 in the opposite direction, the sliding block 622 resets along the arc-shaped rail 621, the cover plate 63 covers the pre-reserved slot 61 again, and then rotates the limiting screw 625, causing its end to insert into the corresponding limiting hole 623, thus fixing the cover plate 63. The arc-shaped rail 621 provides stable guidance for the sliding block 622, ensuring smooth and precise opening and closing of the cover plate 63. The handle-type limiting screw 625 is designed for quick operation, improving ease of use. The limiting holes 623 are evenly spaced along the arc-shaped rail 621, allowing adjustment of the fixed position of the cover plate 63 to meet the opening requirements of different operating scenarios. This structural design makes the opening and closing of the pre-reserved slot 61 simple and efficient, ensuring the sealing of the housing 1 to protect the internal mechanism while allowing for quick opening when needed. This provides ample space for operations such as replacing the yarn feeding and winding roller 33, shortening operation time and improving work efficiency. It solves the problem of inconvenient opening and closing of the equipment housing 1 and its impact on the maintenance and replacement of internal components in the prior art. At the same time, the tight cooperation between the cover plate 63 and the limiting group 62 effectively prevents external dust and impurities from entering the housing 1 through the pre-reserved slot 61, ensuring the operating environment of the internal mechanism and extending the service life of the device.

[0032] The housing 1 is provided with a hot-pressing manifold mechanism at the end away from the drive motor 5. The end of the supply wire 34 extends through the correction module 35 and into the inner side of the hot-pressing manifold mechanism, with its outermost end penetrating the housing 1. The supply wire 34 is conveyed under the action of the transmission module 31. The end of the supply wire 34 passes through the correction module 35 in the middle of the outer side of the transmission module 31, and after correction, extends into the inner side of the hot-pressing manifold mechanism. The hot-pressing manifold mechanism processes the supply wire 34. The hot-pressing manifold mechanism is an existing technology, which has been described in detail in CN202510965345.9.

[0033] In use, the operator pushes the cover plate 63, causing the sliding block 622 to slide smoothly along the arc-shaped rail 621. During this process, the arc-shaped rail 621 provides guidance for the sliding block 622, ensuring the stability of the moving trajectory of the cover plate 63, thereby fully exposing the pre-reserved slot 61 for disassembly and assembly on the front of the housing 1. Then, the limiting screw 625 of the limiting assembly 62 is rotated, causing its end to be pulled out from the limiting hole 623 of the arc-shaped rail 621, releasing the fixation on the cover plate 63, and allowing the yarn feeding take-up roller 33 to... The replacement provides ample operating space; then, by setting the installation module 32, the synchronous adjustment armrest 3236 is operated. Since the two sliders 3234 are connected through the synchronous adjustment armrest 3236, the sliders 3234 on both sides can slide synchronously along the side rail 3231. At this time, the limiting spring 3233 inside the side rail 3231 is stretched, and the locking block 3235 on the outside of the slider 3234 is pulled out from the locking groove 3232 of the mounting block 325, releasing the limitation on the mounting block 325. The feed take-up roller 33, with the feed wire 34 wound around it, is aligned with the entrance of the mounting rail 324 via the mounting block 325. The mounting block 325 is pushed to slide along the mounting rail 324 to the designated position. The synchronous adjustment handle 3236 is released, and the limit spring 3233 resets under its own elasticity, causing the slider 3234 and the locking block 3235 to move back, so that the locking block 3235 is reinserted into the slot 3232, thus completing the fixing of the feed take-up roller 33. After that, the end of the feed wire 34 is passed through the correction guide hole 353 of the correction module 35 and the correction sleeve 355 at the end of the connecting arm 354 in sequence, and finally extends to the inside of the hot pressing confluence mechanism. In this process, through the coordinated cooperation of the limit locking group 323 of the mounting module 32 and the closing mechanism 6, the feed take-up roller 33 can be quickly disassembled and assembled during use, which solves the problem that the winding shaft cannot be quickly replaced in the existing patented device, thereby greatly reducing the time cost of feed replacement and effectively improving the continuity of operation.

[0034] The drive motor 5 is started, and its output end drives the turntable 312 to rotate inside the housing 1. The horizontal plate 313 rotates synchronously with the turntable 312. The gear 321 of the mounting module 32 meshes with the gear ring 311 on the inner side of the housing 1. When the horizontal plate 313 rotates, the gear 321 rolls along the gear ring 311, thereby driving the feed take-up roller 33 to rotate on its own axis while revolving around the center of the turntable 312, continuously releasing the feed wire 34 wound on the outer surface. The support rod 351 fixes the straightening plate 352 in the designated position of the horizontal plate 313, ensuring that the straightening plate 352 is stable in position during the wire feeding process. When the feed wire 34 passes through the straightening guide holes 353 at both ends of the straightening plate 352, the straightening guide holes 353 will initially guide the feed wire 34 to avoid deviation in the initial stage of feeding. Subsequently, the feed wire 34 enters the straightening sleeve 355 at the outer end of the connecting arm 354. The straightening sleeve 355 further constrains the feed wire 34's conveying path, ensuring that the feed wire 34 enters the hot-pressing manifold mechanism in a stable posture. This technical solution, through the synergistic effect of the transmission module 31, allows the feed wires 34 of the two feed winding rollers 33 to naturally form a tight winding state under the dual action of revolution and rotation during use. This, combined with the hot-pressing manifold mechanism, performs manifold processing on the wound feed wires 34, forming a stable twisting effect. This solves the arc dispersion problem caused by wire dispersion in early dual-wire welding, significantly improving the wire's penetration into thick plates and ensuring the penetration depth and weld formation quality during the welding process.

[0035] During the welding process, the hot-pressing confluence mechanism integrates the corrected supply wire 34 to ensure that the welding wire entering the welding area is in a stable state, providing a concentrated heat source for the welding arc. The drive motor 5 can precisely control the release speed of the wire feeding take-up roller 33 by adjusting the output speed, so that the supply wire 34 is fed into the welding area at a speed that matches the welding requirements, meeting the specific requirements of different thickness plates and different welding processes. If it is necessary to pause the operation or replace the wire feeding and take-up roller 33 during the welding process, the above disassembly and assembly steps can be repeated to quickly complete the operation. After the operation is completed, the limit screw 625 of the limit group 62 is reinserted into the corresponding limit hole 623 and tightened to fix the cover plate 63 and close the disassembly and assembly reserved slot 61 to prevent external impurities from entering the housing 1 and affecting the operation of the mechanism. By setting the multiple guide structure of the correction module 35, the correction guide hole 353 and the correction sleeve 355 constrain the wire feeding 34 from different positions, so that the feeding path of the wire feeding 34 can always be stable during use, avoiding welding deviation caused by the offset of the wire feeding 34 and ensuring welding accuracy.

[0036] This invention, through the synergistic effect of its various structures, ensures both welding quality and operational efficiency during use, thereby fully adapting to the demands of continuous and efficient modern welding production and effectively compensating for the shortcomings of existing technologies in balancing quality and efficiency.

[0037] This invention, through the setting of a closed mechanism and an installation module, with the arc-shaped rail, sliding block, and cover plate of the closed mechanism working together to provide a convenient operating opening, and the synchronous adjustment handle of the installation module driving the slider to slide, stretching the limit spring to disengage the locking block from the slot, realizes the quick disassembly and assembly of the wire feeding and winding roller, allowing for rapid replacement of the wire feeding and winding roller during use, reducing replacement time, and thus achieving the effect of improving the continuity of operation and reducing the impact of wire feeding interruption. It solves the problem in the prior art that the winding shaft cannot be quickly disassembled and assembled, resulting in time-consuming replacement after wire feeding and affecting welding efficiency.

[0038] The above embodiments of the present invention are merely illustrative examples and are not the only ones. All modifications within the scope of the present invention or equivalent to the scope of the present invention are encompassed by the present invention.
