Description

Technical Field

[0001] The invention relates to the technical field of automatic painting devices, in particular to an automatic painting device for enameled wire production. Background Art

[0002] Enameled wire is a metal conductor with an insulating varnish coated on its surface. The center of the enameled wire is a metal conductor, usually made of metals with good conductivity such as copper or aluminum. Copper is the most commonly used material because of its excellent conductivity, second only to silver, and it has good mechanical properties and corrosion resistance. Compared with copper enameled wire, aluminum enameled wire has a lower density, lighter weight, and is cheaper. It is used in some applications that have weight requirements or are cost-sensitive. These metal conductors provide a conduction path for electric current and are the basis for enameled wire to achieve its basic electrical function. The insulating varnish is evenly coated on the surface of the metal conductor to act as an insulator. There are many types of insulating varnishes, the most common of which are polyester varnish, polyurethane varnish, polyimide varnish, etc. When producing enameled wire, an automatic painting device is required to apply the insulating varnish to the metal guide surface.

[0003] However, the current painting device achieves the painting of metal wires through a single spraying or dipping process. But when the paint liquid flow rate is too large, the paint layer on the surface of the enameled wire may be too thick, and paint flow and dripping may occur easily. When the flow rate is too small, the paint layer may be too thin, and the expected insulation performance and other requirements may not be met, resulting in poor painting effect. At the same time, the painting device has a low degree of automation, and the enameled wire needs to be manually introduced into the painting device. Multiple machine covers need to be opened when threading, and multiple guide rollers and pressure rollers need to be bypassed. The operation is cumbersome and prone to errors, resulting in reduced painting efficiency. The organic waste gas generated by the volatilization of the paint liquid will evaporate into the air, which is easy to pollute the environment and has poor environmental protection.

When the paint liquid level inside the infiltration pool 203 reaches the lowest level, the liquid level sensor 207 also transmits the liquid level information to the control center, controls the control valve 213 to be opened, and the reflux valve 210 to be closed, so as to replenish the paint liquid inside the infiltration pool 203 in time, thereby improving the painting effect.

[0044] Then, when threading is required, first control the first hydraulic cylinder 402 to make the multiple bottom frames 403 and the guide rollers 404 in a low position, control the second hydraulic cylinder 410 to control the top frame 407 and the multiple pressure rollers 408 in a high position, then pass the metal wire around the wire dividing wheel 8, and then use the hexagonal wrench to rotate the bolt 312 so that the bolt 312 no longer conflicts with the clamping plate 308. At this time, the bolt 312 and the clamping plate 308 can be removed, and then the multiple metal wires are placed at the perforation 306 in turn, and then the clamping plate 308 is installed so that the positioning hole 309 on the clamping plate 308 is plugged into the positioning column 307 on the slide plate 302, and the abutment plate 310 at the bottom end of the clamping plate 308 conflicts with the metal wire, and then the bolt 312 is rotated, and the bolt 312 continuously conflicts with the clamping plate 308, so that the clamping plate 308 fully clamps the multiple metal wires. After the multiple metal wire heads are fixed, start The motor 305 drives the screw rod 303 to rotate, and the screw rod 303 rotates to drive the slide plate 302 to slide on the guide rail 301, and then the metal wire is pulled to the outlet end of the coating machine 1. The setting of the guide rod 304 improves the stability of the slide plate 302 when sliding, and then the wire is slowly released. At this time, the first hydraulic cylinder 402 and the second hydraulic cylinder 410 can be started. The first hydraulic cylinder 402 extends to drive the bottom frame 403 to rise, and the bottom frame 403 drives the guide roller 404 to rise. The second hydraulic cylinder 410 extends to drive the top frame 407 to descend, and then drives the pressure roller 408 to descend, and the passed wire is pressed into the infiltration tank 203. The setting of the guide column 406 improves the stability of the bottom frame 403 when sliding, and then the multiple metal wires are passed around the wire dividing wheel 8 at the outlet end of the coating machine 1, and then the multiple metal wires are fixed on the winding drum of the winding device;

[0045] Secondly, after the wire is passed, the third hydraulic cylinder 503 can be started. The third hydraulic cylinder 503 contracts to drive the mounting bar 502 and the sliding column 501 to descend, thereby driving the upper mounting plate 505 and the scraper 506 to descend. The upper scraper 506 and the lower scraper 506 are then spliced ​​together to wrap the metal wire. Both ends of the scraping groove 507 on the scraper 506 are truncated cone structures, which are convenient for scraping paint on metal wires at different angles. When there is more paint liquid on the metal wire, it will be scraped off by the scraper 506 as the metal wire moves and drip back into the infiltration tank 203. When it is necessary to scrape paint on metal wires of different diameters, the third hydraulic cylinder 503 can be opened first. The second machine cover 202, and then press the pressing block 508 on the scraper 506, the pressing block 508 drives the slide bar 509 to slide, the sliding of the slide bar 509 drives the card block 510 to no longer engage with the card slot 511 on the mounting plate 505, at this time, the scraper 506 can be slid out, and the scraper 506 with a different diameter scraper slot 507 can be replaced, and then the new scraper 506 is inserted into the mounting plate 505, and the spring 513 resets to drive the slide bar 509 to slide, and then drives the card block 510 to engage with the card slot 511 on the mounting plate 505, and the setting of the fixed shaft 512 improves the stability of the sliding of the slide bar 509 and prevents the spring 513 from running off;

[0046] Finally, the painted metal wire will be dried in the drying boxes 7 arranged on the two sides, and the vacuum pump 604 will be started at the same time. The vacuum pump 604 will extract the organic waste gas generated by the paint liquid inside the paint coating machine 1 through the connecting hose 603, the vacuum pipe 602 and the suction hood 601. The air outlet of the vacuum pump 604 is connected to the waste gas treatment equipment through a pipeline, which is convenient for treating the waste gas and improving the environmental protection of the equipment. At the same time, the air flow rate in the drying area is accelerated, so that the hot air rises quickly to dry the enameled wire, thereby improving the drying effect. When the drying box 7 needs to be inspected and repaired, the hydraulic rod 605 can be started, and the hydraulic rod 605 drives the connecting block 606 to move, and the connecting block 606 drives the second machine cover 202 to move. The second machine cover 202 drives the slider 608 to slide inside the slide groove 607. The setting of the slider 608 and the slide groove 607 improves the sliding stability of the second machine cover 202. When the second machine cover 202 is removed, the internal oven can be inspected and maintained, and the scraper 506 can be replaced conveniently.
