Description

Technical Field

[0001] This invention belongs to the field of metal panel technology, and specifically relates to a device for applying a corrosion-resistant coating to metal panels. Background Technology

[0002] Common metal decorative panels are made by hot-pressing various colored aluminum foils onto the surface of MDF sheets, creating single-sided and double-sided panels with various patterns and styles. These include brushed and painted effects, among others. Because aluminum foil itself is metal, it possesses a bright metallic texture. Combined with patterned treatments, this allows for greater diversity in the types of metal panels available, meeting the needs of various furniture, integrated metal cabinets, interior backgrounds, and more, resulting in a more elegant and sophisticated look. Unlike melamine boards, it also has fire-retardant and waterproof properties, making it an ideal material for decoration. It is especially suitable for large public spaces. [The company behind this product is located in China.] Metal decorative panels are environmentally friendly and elegant, making them an ideal choice for home decoration.

[0003] Metal panel surfaces require anti-corrosion coating. In the market, the coating process is usually done by hand spraying liquid or by squeezing with two rollers. Neither of these methods can achieve uniform liquid spraying. On the one hand, hand spraying is inefficient and produces poor results. On the other hand, squeezing between rollers causes clumping in the gaps between the rollers, resulting in uneven spraying and high costs. Summary of the Invention

[0033] like Figure 1 - Figure 10 As shown, a metal panel corrosion-resistant coating application device according to the present invention includes a base 1. Adjustment mechanisms 2 for clamping and rotating the metal panel are fixedly provided on both sides of the inner wall of the base 1. The adjustment mechanism 2 includes a first motor 21, a housing 22, a second motor 23, a first electric push rod 24, and a clamping assembly 25 for clamping the metal panel. The first motor 21 is fixedly mounted on the top wall of the base 1, and its output end is fixedly mounted on a lead screw slide. The housing 22 is threaded onto the lead screw slide, and a sliding groove for sliding the housing 22 is provided on the inner wall of the base 1. The second motor 23 is fixedly mounted on the inner wall of the housing 22, and the first electric push rod 24 is fixedly mounted on its output end. The clamping assembly 25 is fixedly mounted on the output end of the first electric push rod 24. Lead screw slides are fixedly provided on both sides of the outer wall of the base 1. A third motor 3 is fixedly mounted on the outer wall of the base 1, and its output end is fixedly connected to one set of lead screw slides. A chain drive is provided between the two lead screw slides. The top is equipped with a spraying mechanism 4 for spraying metal panels, and the bottom of the spraying mechanism 4 is slidably mounted on two lead screw slides. The base 1 has a groove inside, and a protective plate is slidably mounted inside the groove. Both sides of the base 1 are equipped with lifting mechanisms 5 for raising and lowering the protective plate. Both sides of the inner wall of the base 1 are equipped with wiping components 6 for wiping the protective plate. By setting an adjustment mechanism 2, the adjustment mechanism 2 can be adapted to various types of metal panels and can apply a coating to the clamping surface, thereby avoiding the problem of the clamping surface being unable to be sprayed with liquid. In addition, by setting a cleaning agent nozzle, the coated area of ​​the clamping surface can be cleaned periodically to prevent clumping and unusable next time. The metal panel is sprayed by the spraying mechanism 4. Before spraying after lowering, the lifting mechanism 5 is activated to raise the protective plate, so that the protective plate protects the health of the workers from liquid splashes. At the same time, the interior can be visualized. After spraying, the protective plate can be wiped by the wiping components 6 for reuse.

[0034] The clamping assembly 25 includes a C-shaped plate 251, a second electric push rod 252, a pressing rod 253, a measuring cylinder 254, a hollow plate 255, and a coating layer 256. The C-shaped plate 251 is fixedly mounted to the output end of the first electric push rod 24. Multiple second electric push rods 252 are symmetrically arranged on the C-shaped plate 251. The pressing rod 253 is fixedly mounted to the output end of the second electric push rod 252 and extends into the measuring cylinder 254, slidingly mounted on the inner wall of the measuring cylinder 254. The measuring cylinder 254 is fixedly mounted inside the hollow plate 255. The coating layer 256 is fixedly mounted at the bottom of the hollow plate 255. Water pipes are inserted between the multiple measuring cylinders 254, extending out of the hollow pipes. First, the first motor 21 is started to lift two boxes, lifting the metal surface to be coated. The plate is placed between two clamping components 25. The distance between the two clamping components 25 is adjusted according to the size of the metal panel by the first electric push rod 24. The second electric push rod 252 is activated to descend, so that the coating layer 256 under the two hollow plates 255 clamps the metal panel. In order to avoid the metal panel being unable to be sprayed at the clamping point, the push rod is driven to slide and squeeze inside the measuring cylinder 254 during the process of squeezing the hollow plate 255, thereby squeezing the paint inside the measuring cylinder 254 onto the coating layer 256. During the process of the two hollow plates 255 clamping and pressing the panel, the coating layer 256 is applied to the clamping points on both sides of the panel. After clamping is completed, the first motor 21 is activated to drive the clamping components 25 downward into the base 1.

[0035] Secondly, the spraying mechanism 4 includes a support and adjustment assembly 41 and a spraying assembly 43. The support and adjustment assembly 41 and the spraying assembly 43 are fixedly arranged. The support and adjustment assembly 41 includes a first rod 411, a second rod 412, a third rod 413, a fourth rod 414, a first collar 415, a second collar 416, a third collar 417, a third electric push rod 418, and a contact head 419. The first rod 411 and the second rod 412 are each slidably mounted on two lead screw slides. The first collar 415 and the second collar 416 are respectively mounted on the first rod 411 and the second rod 412 by return springs. On body 412, the third rod 413 and the fourth rod 414 are respectively fixed on the first collar 415 and the second collar 416. The spraying assembly 43 is fixed between the third rod 413 and the fourth rod 414. The third electric push rod 418 is fixed on the first rod 411 and its output end is fixed to the first collar 415. The third collar 417 is slidably mounted on the first rod 411 by a reset spring. A fixing rod is fixed between the first collar 415 and the third collar 417. The third collar 417 is fixed to the contact head 419. A switch 42 is fixedly mounted on one side wall of the base 1.

[0036] Preferably, the spraying assembly 43 includes a support plate 431, a spraying box 432, a first nozzle 433, and a second nozzle 434. The support plate 431 is fixedly disposed between the third rod 413 and the fourth rod 414. The spraying box 432 is fixedly disposed on the top of the support plate 431. The spraying box 432 has a first chamber and a second chamber inside. Multiple first nozzles 433 and multiple second nozzles 434 are provided. The first nozzle 433 extends into the first chamber, and the second nozzle 434 extends into the second chamber. Before spraying, the spraying agent and cleaning agent are filled into the first chamber and the second chamber, respectively. After placement, the spraying assembly 43 is lowered to tighten the position of the spraying assembly 43 with the metal panel. The closer the distance, the greater the water pressure and the denser the spraying effect. The third electric push rod 418 is activated, causing the third electric push rod 418 to drive the first collar 415 to descend. During the descent, it simultaneously... The second ring 416 slides on the second rod 412, thereby driving the third rod 413 and the fourth rod 414 to move up and down, further driving the spraying assembly 43 to move. On the other hand, the first ring 415 descends and drives the third ring 417 to slide down through the fixed rod, causing the third ring 417 to drive the abutment rod to descend, thereby driving the abutment rod to touch the switch 42 to start the lifting assembly, causing the lifting assembly to drive the protective plate to rise, further preventing liquid splashing during the spraying process. When spraying is not required, the protective plate will automatically retract with the spraying mechanism 4, thus saving space and maintaining the processing environment. After descending to the position where spraying is required, the third motor 3 is started to drive the spraying mechanism 4 to perform left and right movement spraying on the lead screw slide. After one side of the metal panel is sprayed, the second motor 23 is started to drive the panel to flip and then spray the second side.

[0037] Then, the lifting mechanism 5 includes a fourth motor 51, a first bevel gear 52, a second bevel gear 53, a rotating cylinder 54, a fixed cylinder 55, and a lifting rod 56. There are multiple fixed cylinders 55 and they are fixedly installed in the groove. The rotating cylinder 54 is rotatably installed on the top wall of the fixed cylinder 55 through a bearing. The lifting rod 56 is slidably installed in the fixed cylinder 55 and threadedly installed with the rotating cylinder 54 and extends out of the rotating cylinder 54. The multiple rotating cylinders 54 are connected by a chain drive. The lifting rod 56 is fixedly installed with a protective plate. The first bevel gear 52 is fixedly installed with the outer wall of the rotating cylinder 54. The fourth motor 51 is fixedly installed on the inner wall of the base 1, and its output end is fixedly installed with the second bevel gear 53. The first bevel gear 52 and the second bevel gear 53 are meshed.

[0038] Preferably, the wiping assembly 6 includes a fifth motor 61 and a wiping plate 62. A lead screw slide is fixedly provided on the inner wall of the base 1. The fifth motor 61 is fixedly mounted on the base 1 and its output end is fixedly mounted to the lead screw slide. The wiping plate 62 is threaded onto the lead screw slide and slidably mounted on the inner wall of the base 1. The wiping plate 62 abuts against the inner wall of the protective plate. When the switch 42 is activated, the switch 42 drives the fourth motor 51 to rotate. The fourth motor 51 drives the second bevel gear 53 to rotate. The second bevel gear 53 drives the first bevel gear 52 to rotate. The first bevel gear 52 drives the rotating drum 54 to rotate. The rotating drum 54 drives the lifting rod 56 to slide upwards. The system is raised, causing multiple lifting rods 56 to simultaneously raise the protective plate for splash protection. The protective plate is a visible plate, allowing observation of the internal coating process even after it has risen. After spraying is complete, the original steps are followed to reactivate the switch 42, causing the protective plate to retract. Once retracted, the fifth motor 61 can be activated to drive the wiping plate 62 to wipe away any splashed liquid from the inner wall of the protective plate. It should be noted that when spraying is no longer required, the original steps can be repeated to spray cleaning agent through the spray box 432 to clean the entire interior of the device, extending its service life and reducing costs.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., should be included within the scope of protection of the present invention.
