Description

Technical Field

[0001] The invention relates to the technical field of enameled wire production, in particular to an automated production line for continuous annealing-varnishing-cooling of enameled wires. Background Art

[0002] Enameled wire is a conductive metal wire with an insulating layer. It is widely used in motors, electrical appliances, electronics and other fields. Its core structure is to evenly coat one or more layers of insulating varnish on the surface of the conductor. After baking and curing, a smooth and tough paint film is formed. The enameled wire has significant performance advantages. The insulating paint film can effectively prevent current leakage and ensure the safe and stable operation of the circuit. Its thin and uniform shape can be tightly wound, saving space and improving the power density of the equipment.

[0003] The production process of enameled wire covers multiple links: first, wire drawing is carried out to evenly release the copper or aluminum material, providing stable raw materials for subsequent processes. Then it enters the annealing stage, where the wire is softened by heating, the internal stress caused by stretching is eliminated, and the flexibility and conductivity are enhanced. Next is painting, using a mold or felt to evenly apply the insulating paint on the surface of the conductor to form a preliminary paint layer. After that, it is dried. Through precise temperature control, the solvent in the paint liquid evaporates, the paint-based material solidifies, and a solid paint film is formed. This process needs to be repeated many times to ensure the quality of the paint film. After baking, it needs to be cooled in time to ensure that the paint film is stably formed to prepare for subsequent painting; finally, the wire is taken up, and the finished enameled wire is tightly and evenly wound on the bobbin for easy transportation and processing.

[0004] During the traditional enameled wire painting process, the tension of the copper wire in the paint pool is not fixed. The tension adjustment of traditional painting equipment often relies on mechanical adjustment devices, such as springs. These devices are difficult to achieve stable control when adjusting the tension. Especially in the high-speed painting process, slight changes in tension may lead to uneven painting. Therefore, in order to solve the above problems, an automated production line for continuous annealing, painting and cooling of enameled wire is proposed. Summary of the Invention

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example like Figures 1-14 As shown, the present invention proposes an automated production line for continuous annealing, painting, and cooling of enameled wire, comprising a pay-off rack 1, a wire drawing oil tank 20, a tubular annealing furnace 31, a painting box 40, and a drying and cooling furnace 51. The painting box 40 is provided with a tension adjustment assembly, which includes an adjustment bracket 44. The adjustment bracket 44 is symmetrically provided with circularly movable winding rollers 445. A plurality of spacers 446 are fixedly connected equidistantly between the two winding rollers 445. The two winding rollers 445 are used to tighten or relax the copper wire. A swing assembly is provided within the paint box 40. The swing assembly includes two sets of guide rails 4611. Threaded brackets 4610 are slidably provided on the two guide rails 4611. A plurality of fixed guide wheels 4613 and fixed guide plates 4615 are mounted on the threaded brackets 4610. The fixed guide wheels 4613 and fixed guide plates 4615 are used to restrain the copper wires. The threaded brackets 4610 are used to stagger the copper wires for uniform painting. A guide assembly is provided inside the paint box 40, and the guide assembly includes a fixed bracket 47, on which a plurality of angle-reversible auxiliary guide discs 475 are mounted, and the auxiliary guide discs 475 are used to guide the copper wire; Furthermore, in the automated production line for continuous annealing, painting and cooling of enameled wire, the pay-off rack 1 serves as the starting end, stably releasing the copper wire to be processed. After the copper wire is drawn out from the pay-off rack 1, it enters the wire drawing oil tank 20, where it is lubricated and drawn to achieve the required diameter specification, and then the copper wire is wound into a wire roller. Furthermore, the copper wire enters the tubular annealing furnace 31, which adjusts the temperature and heating time through a PLC control system to anneal the copper wire. This process can eliminate the internal stress generated in the copper wire during the wire drawing process and improve its crystal structure. Furthermore, after the copper wire emerges from the tubular annealing furnace 31, it undergoes painting. Within the painting box 40, the swing assembly and tension adjustment assembly work in concert, causing the copper wire to exhibit a staggered movement under the guidance of the fixed guide wheel 4613 and the fixed guide plate 4615. This staggered movement ensures that the copper wire is fully exposed to the paint during the painting process, ensuring that the paint evenly covers the copper wire surface. Furthermore, the movement state of the copper wire in the paint box 40 is similar to a wave shape. At this time, the tension of the copper wire changes in real time. Therefore, the tension adjustment component provided on the paint box 40 controls the forward and reverse circular motion of the two winding rollers 445 through the PLC. The copper wire passes through the two winding rollers 445 in an S shape. When the tension needs to be increased, the winding rollers 445 are controlled to rotate so that the copper wire is wound on the two winding rollers 445, thereby increasing the tension on the copper wire. Conversely, when the tension needs to be reduced, the winding rollers 445 rotate in the opposite direction to release the copper wire wound on the two winding rollers 445, thereby reducing the tension. Furthermore, the guide assembly provided inside the painting box 40 is used to assist the staggered movement of the copper wire. The multiple angularly flippable direction-adjusting auxiliary guide discs 475 can flexibly adjust the angle according to the direction of the copper wire and the painting requirements. When the copper wire moves in the painting box 40, the direction-adjusting auxiliary guide discs 475 can guide the copper wire to change direction so that it can better cooperate with the fixed guide wheel 4613 and the fixed guide disc 4615, while ensuring the stability of the copper wire during the painting process, avoiding jitter or deviation of the copper wire, and further improving the accuracy and uniformity of the painting. Furthermore, after the painting is completed, the copper wire enters the drying and cooling furnace 51. In the drying and cooling furnace 51, the solvent in the paint film is evaporated by a heating device, and the paint-based material is solidified to form a solid insulating paint film. Subsequently, the enameled wire is quickly cooled by a cooling device to stabilize the paint film structure, and finally an enameled wire product that meets the quality requirements is obtained.

[0022] A wire drawing mobile console 2 is installed at the bottom of the wire drawing oil tank 20, a wire drawing guide wheel frame 21 is fixedly connected to the side of the wire drawing oil tank 20, a wire drawing take-up roller 23 is installed on the side of the wire drawing oil tank 20 away from the wire drawing guide wheel frame 21, a wire drawing roller 22 is symmetrically rotated on the inner side of the wire drawing oil tank 20, and a wire drawing tool 24 fixedly connected to the wire drawing oil tank 20 is provided between the wire drawing rollers 22; An annealing furnace bracket 3 is installed at the bottom of the tubular annealing furnace 31, an annealing exhaust gas collection cover 32 is installed on the top of the tubular annealing furnace 31, an annealing furnace wire take-up frame 33 is fixedly connected to the side of the annealing furnace bracket 3, an annealing wire pay-off roller 30 is installed on the side of the annealing furnace bracket 3 away from the annealing furnace wire take-up frame 33, a drying exhaust gas collection cover 50 is installed on the top of the drying and cooling furnace 51, a drying wire pay-off frame 5 is fixedly connected to the side of the drying and cooling furnace 51, and a drying wire take-up frame 52 is installed on the side of the drying and cooling furnace 51 away from the drying wire pay-off frame 5; Furthermore, in the metal wire processing flow, the wire drawing mobile control console 2 installed at the bottom of the wire drawing oil tank 20 can control the wire drawing process, and the wire drawing guide wheel frame 21 fixedly connected on the side is used to guide the direction of the wire to ensure that the wire can smoothly enter the wire drawing oil tank 20. The wire drawing take-up roller 23 installed on the side away from the wire drawing guide wheel frame 21 is responsible for orderly winding the wire after the wire drawing is completed. The wire drawing roller 22 symmetrically rotated and connected to the inside of the wire drawing oil tank 20 generates tension on the wire through its rotation, so that when the wire passes through the wire drawing device tooling 24 in the wire drawing oil tank 20, the wire diameter is reduced under the action of the wire drawing device tooling 24, completing the wire drawing process and obtaining a wire that meets the size requirements; Furthermore, the wire is guided to the tubular annealing furnace 31 area. The annealing furnace support 3 installed at the bottom of the tubular annealing furnace 31 plays a role in providing stable support. The wire enters the tubular annealing furnace 31, where the tubular annealing furnace 31 heats the wire to eliminate the internal stress generated during the wire drawing process, improve the mechanical properties of the wire, make it softer, and facilitate subsequent processing. At the same time, the annealing exhaust gas collection hood 32 installed on the top of the tubular annealing furnace 31 can collect the exhaust gas generated during the annealing process to prevent the exhaust gas from escaping and polluting the environment. Furthermore, after the wire is painted, the wire enters the drying and cooling furnace 51 from the drying and cooling furnace 51 from the drying and cooling rack 5 fixedly connected to the side of the drying and cooling furnace 51. The drying and cooling furnace 51 dries and cools the wire. The solvent in the paint film is evaporated through the heating device, and the paint-based material is solidified to form a solid insulating paint film. Subsequently, the enameled wire is rapidly cooled through the cooling device to stabilize the paint film structure, and finally an enameled wire product that meets the quality requirements is obtained. The drying waste gas collection hood 50 installed on the top of the drying and cooling furnace 51 is used to collect the waste gas generated during the drying process, and the drying take-up rack 52 installed on the side of the drying and cooling furnace 51 away from the drying pay-out rack 5 is used to reel up the processed wire.

[0023] The tension adjustment assembly also includes an adjustment motor 440 mounted on the adjustment bracket 44. The two adjustment brackets 44 are fixedly connected to the paint box 40. The output end of the adjustment motor 440 is fixedly connected to a transmission rod 441 that is rotatably connected to the adjustment bracket 44. The transmission rod 441 is fixedly connected to both ends of the adjustment bracket 44 with a pinion 442. The two adjusting brackets 44 are rotatably connected to the opposite sides of each other with an adjusting disk 444. The outer side of the adjusting disk 444 is fixedly connected to a large ring gear 443. The large ring gear 443 and the small gear 442 are meshed with each other. The two winding rollers 445 are fixedly connected between the two adjusting disks 444. Furthermore, during the process of adjusting the tension of the copper wire, the adjusting motor 440 is started, and the rotation of the output end of the adjusting motor 440 drives the transmission rod 441 to rotate synchronously. The transmission rod 441 is fixedly connected to the two ends of the adjusting bracket 44 with a small gear 442. As the transmission rod 441 rotates, the small gear 442 also rotates. The large ring gear 443 and the small gear 442 are meshed with each other. According to the principle of gear transmission, the rotation of the small gear 442 drives the large ring gear 443 to rotate, thereby rotating the adjusting disk 444, and the two winding rollers 4 45 is fixedly connected between the two adjusting disks 444. When the adjusting disk 444 rotates, the winding roller 445 is driven to rotate. During the painting operation, the wire is wound around the winding roller 445. By adjusting the forward and reverse rotation and speed change of the motor 440, the rotation of the transmission rod 441, the small gear 442, the large ring gear 443, the adjusting disk 444 and the winding roller 445 is controlled, thereby changing the tension of the wire during the winding process, avoiding the problems of wire stretching and deformation due to excessive tension or wire loosening and uneven painting due to too little tension.

[0024] The swing assembly also includes a swing motor 46 symmetrically mounted on both sides of the paint box 40. The output end of the swing motor 46 is fixedly connected to a first transmission shaft 461. A driving bevel gear 462 is mounted on the side of the paint box 40 close to the first transmission shaft 461. Both sides of the paint box 40 are fixedly connected to a first bearing seat 463. The first bearing seat 463 is rotationally connected to the first transmission shaft 461. The driving bevel gears 462 are symmetrically mounted on the first transmission shaft 461, and the two driving bevel gears 462 face opposite directions. A second bearing seat 464 is symmetrically fixedly connected to one side of the swing motor 46 close to the first transmission shaft 461, and a second transmission shaft 460 is rotatably connected to the second bearing seat 464. A driven bevel gear 466 is installed on the end of the second transmission shaft 460 close to the active bevel gear 462. The driven bevel gear 466 and the active bevel gear 462 are meshed with each other. A driving disc 465 is also fixedly connected to the end of the second transmission shaft 460 away from the driven bevel gear 466. A slot plate 467 is slidably provided on the driving disc 465. A sliding shaft 469 is fixedly connected between the slot plate 467 and the guide rail 4611, and the sliding shaft 469 slides relative to the paint box 40. There are two guide rails 4611 in each group. Each group of guide rails 4611 is staggered and moves in opposite directions relative to the paint box 40. A lifting motor 468 is installed on the top of the guide rails 4611. The output end of the lifting motor 468 is fixedly connected to a lifting screw 4612 that is rotatably connected to the guide rails 4611. The two lifting screws 4612 are threadedly connected to a threaded bracket 4610. A mounting shaft 4614 is fixedly connected to the threaded bracket 4610. A fixed guide plate 4615 is fixedly connected to the mounting shaft 4614. The fixed guide wheel 4613 and the fixed guide plate 4615 are in a vertical position on the axis. Furthermore, in the swing assembly, the copper wires are staggered to move, so that the relative moving contact surface between the copper wires and the paint liquid is constantly changing. When the swing motor 46 is started, the swing motor 46 drives the first transmission shaft 461 to rotate. The first transmission shaft 461 is symmetrically mounted with driving bevel gears 462 facing in opposite directions. When the first transmission shaft 461 rotates, the driving bevel gears 462 will rotate synchronously therewith. Furthermore, according to the principle of bevel gear transmission, when the driving bevel gear 462 rotates, it drives the driven bevel gear 466 to rotate, thereby rotating the second transmission shaft 460. Since the two driving bevel gears 462 face opposite directions, the two driven bevel gears 466 meshing therewith also rotate in opposite directions, causing the two second transmission shafts 460 to rotate in opposite directions.

[0025] Furthermore, when the second transmission shaft 460 rotates, it will drive the toggle disc 465 to rotate. During the rotation of the toggle disc 465, its edge will periodically toggle the slot plate 467. Since the slot plate 467 is connected to the guide rail 4611 through the sliding shaft 469, and the sliding shaft 469 can slide relatively on the paint box 40, the slot plate 467 will drive the guide rail 4611 to perform reciprocating linear motion. Because the two second transmission shafts 460 rotate in opposite directions, the reciprocating motion directions of the two sets of guide rails 4611 are also opposite.

[0026] Furthermore, during the installation of the copper wire, the lifting motor 468 is started, and its output end drives the lifting screw 4612 to rotate. According to the principle of screw transmission, the threaded bracket 4610 will perform lifting and lowering movements driven by the lifting screw 4612. The threaded bracket 4610 is fixedly connected to the installation shaft 4614, and the fixed guide plate 4615 is fixedly connected to the installation shaft 4614. The fixed guide wheel 4613 and the fixed guide plate 4615 are in the same vertical position. Therefore, when the threaded bracket 4610 is lifted or lowered, it will drive the installation shaft 4614, the fixed guide plate 4615 and the fixed guide wheel 4613 to lift or lower together. Then the staff will pass the copper wire through the gap between the fixed guide plate 4615 and the fixed guide wheel 4613.

[0027] The guide assembly also includes an electric telescopic rod 470 mounted on the outside of the paint box 40. The telescopic end of the electric telescopic rod 470 is fixedly connected to a pull rod 471 that slides relative to the paint box 40. A plurality of auxiliary guide plates 475 for adjusting the direction are movably connected to the pull rod 471. A fixed bracket 47 is fixedly connected to the inside of the paint box 40. The fixed bracket 47 is located between the two sets of guide rails 4611. A mounting rod 473 is fixedly connected to the fixed bracket 47. A plurality of ball bearings 474 are mounted on the mounting rod 473. The ball bearings 474 are rotatably connected to the auxiliary guide plates 475 for adjusting the direction. A plurality of baffles 472 are fixedly connected to the bottom of the fixed bracket 47. Furthermore, the direction of the wire changes in real time during the cross movement. Therefore, by activating the electric telescopic rod 470, since the telescopic end of the electric telescopic rod 470 is fixedly connected to the pull rod 471 that slides relative to the paint box 40, the movement of the telescopic end of the electric telescopic rod 470 will drive the pull rod 471 to slide synchronously on the paint box 40. Furthermore, when the pull rod 471 slides, it drives all the auxiliary guide plates 475 to move together. The presence of the ball bearing 474 allows the auxiliary guide plates 475 to flexibly rotate around the axis of the ball bearing 474 while moving with the pull rod 471. This design not only ensures that the auxiliary guide plates 475 can adjust their positions along with the pull rod 471, but also allows the auxiliary guide plates 475 to adaptively rotate according to the direction of the wire, thereby better guiding the wire. Furthermore, during the painting process, the wire rods will sequentially pass through these auxiliary guide plates 475. By driving the pull rod 471 and the auxiliary guide plates 475 to move via the electric telescopic rod 470, the path of the wire rods in the painting box 40 can be changed, so that the wire rods can be painted along a preset trajectory, ensuring uniformity and comprehensiveness of the painting. In addition, a plurality of baffles 472 are fixedly connected to the bottom of the fixed bracket 47 , and the baffles 472 are in contact with the auxiliary guide plate 475 to prevent the wire from shaking and falling off the auxiliary guide plate 475 .

[0028] A paint support 4 is installed at the bottom of the paint box 40, a paint feeding pipe 41 and a paint exhaust gas collection cover 42 are installed at the top of the paint box 40, and a hydraulic rod 43 is also installed on the top of the paint box 40. The telescopic end of the hydraulic rod 43 is installed with an upper coating plate 430. The inner side of the paint box 40 is fixedly connected to the lower coating plate 431. A roller 45 is installed on the side of the paint box 40 away from the fixed support 47; Furthermore, the paint delivery pipe 41 installed on the top of the paint box 40 is a key channel for paint delivery. The external paint supply system delivers an appropriate amount of paint to the interior of the paint box 40 through the paint delivery pipe 41. During the painting process, waste gas containing harmful components such as volatile organic compounds is generated. The paint waste gas collection cover 42 installed on the top of the paint box 40 collects the waste gas generated in the paint box 40 to prevent the waste gas from spreading to the surrounding environment. Furthermore, when painting operations are being performed, the hydraulic system is started, and hydraulic oil is injected into the hydraulic rod 43, causing the telescopic end of the hydraulic rod 43 to extend downward, driving the upper coating plate 430 mounted thereon to move downward, and the lower coating plate 431 fixedly connected to the inner side of the paint box 40 corresponds to the upper coating plate 430. During the painting process, the wire will pass between the upper coating plate 430 and the lower coating plate 431. As the upper coating plate 430 moves downward, the distance between the upper coating plate 430 and the lower coating plate 431 gradually decreases, eventually sandwiching the wire in the middle, and the relative surfaces of the upper and lower coating plates are usually designed with specific shapes and textures, which can evenly apply the paint to the surface of the wire and scrape off excess paint to achieve the painting operation.

[0029] Furthermore, after the painting operation, when the wire is led out of the paint box 40, the roller 45 provides a stable support point for the wire, so that the wire can be smoothly led out of the paint box 40, avoiding problems such as shaking or sagging of the wire due to its own gravity or external factors, thereby ensuring the smooth progress of the painting process.

[0030] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
