Description
Technical Field
[0001] The present invention relates to the technical field of conductive foam, and in particular to a conductive foam high-efficiency coating device. Background Art
[0002] Conductive foam is a foam material with conductive properties. It is typically composed of a foam base material and a conductive material. Common foam base materials include polyurethane and polyethylene, and have a porous structure. This makes the conductive foam soft and elastic, allowing it to conform well to various irregular surfaces. The conductive material, which may be silver powder, copper powder, carbon black, etc., is evenly dispersed in the foam base material or coated on the foam surface. This material retains the cushioning, shock absorption, and sealing properties of foam while also imparting its conductive function. It is commonly used in scenarios such as electromagnetic shielding, grounding connections, and conductive contact between batteries and devices in electronic products. It can effectively prevent electromagnetic interference and ensure the normal operation of electronic equipment.
[0003] Currently, conventional high-efficiency conductive foam coating devices first coat the entire strip of conductive foam. However, the coated conductive foam often retains a certain amount of heat, necessitating subsequent cutting for subsequent use. However, if conventional cutting devices directly cut this heated, coated conductive foam, the coating easily adheres to the cutting blades. This significantly affects not only the smoothness of the cut but also the precision of the cut, disrupting the normal cutting process and causing significant inconvenience in production.

When the first gear 403 rotates, the rotating disk 405 rotates synchronously, and the second gear 407 is rotatably mounted on the upper both sides of the interior of the equipment bracket 404, and a connecting shaft 408 is fixedly mounted on the inner side of the second gear 407. 6. The rotating disk 405 and the second gear 407 are meshed with each other through the meshing tooth block 406. Through the provided cutting mechanism 4, while the transmission mechanism 2 is driven by the driving motor 201, the second tooth block 401 and the first gear 403 are connected to each other through the second transmission belt 402, thereby driving the first gear 403 on the outside of the equipment bracket 404 to rotate synchronously and continuously, so that the rotating disk 405 on the inside of the equipment bracket 404 rotates continuously, and the rotating disk 405 drives the transmission plate 411 and the inner rack 412 fixed at the lower end and the cutting blade 413 to slide back and forth up and down through the rotating rod 410, and the conductive foam is quantitatively cut by the cutting blade 413. At the same time, the rotating disks 405 on both sides are rotated synchronously by the upper second gear 407 and the connecting shaft 408, thereby ensuring that the inner rack 412 and the cutting blade 413 can slide back and forth more smoothly, ensuring that the quantitative cutting of the conductive foam is accurate and stable, and improving the cutting quality and efficiency.
[0042] Example 4:
[0043] The cleaning mechanism 5 includes a scraper 503 and an outer rack 501. The scraper 503 is rotatably mounted on the lower end of the outer rack 501, and the outer rack 501 is movably mounted on the inner side of the equipment bracket 404. Meshing rollers 504 are rotatably mounted on both sides of the interior of the equipment bracket 404. The meshing rollers 504 are respectively engaged with the outer rack 501 and the inner rack 412. A fixed plate 505 is fixedly mounted on the inner side of the equipment bracket 404. The transmission plate 411 and the outer rack 501 are both slidably mounted on the inner surface of the fixed plate 505. A limiting block 502 is fixedly mounted on the upper part of the outer rack 501, and a baffle 505 is fixedly mounted on the inner lower part of the outer rack 501. A spring structure 506 is installed between the lower surface of the baffle 505 and the upper surface of the scraper 503 to ensure that the scraper 503 is always in close contact with the lower side surface of the cutting blade 413.
[0044] When in use, after the device is started, the driving motor 201 drives the first gear block 203 and the second gear block 401 to rotate through the transmission shaft 202, and the first transmission belt 204 transmits power to the transmission roller 206, so that the transmission roller 206 rotates synchronously. The surface of the transmission roller 206 is provided with a plurality of limit grooves 209 for placing the conductive foam. Through the transmission mechanism 2, the conductive foam is continuously transmitted to the coating mechanism 3. In the coating mechanism 3, the hot pressing roller 303 guides the coating material 304 through the driving roller 302 and drives the transmission roller 206. When the conductive foam reaches the coating mechanism 3, the coating material 304 is evenly hot-pressed on the upper and lower surfaces of the conductive foam by the hot pressing roller 303 to achieve synchronous coating. This process is driven by the drive motor 201 to drive the transmission shaft 202 to rotate, thereby realizing the automation of the transmission and coating of the conductive foam. In the cutting mechanism 4, the inner rack 412 is fixedly installed at the lower end of the transmission plate 411, and the cutting blade 413 performs quantitative cutting by the reciprocating sliding of the inner rack 412 up and down. The cutting blade 41 When the cutting blade 413 moves downward, the outer rack 501 and the scraper 503 are driven to slide upward by the meshing roller 504, thereby preventing the coating material 304 from adhering to the surface of the cutting blade 413. At the same time, the scraper 503 is closely attached to the two side surfaces of the cutting blade 413, adhering the coating material 304, thereby automatically cleaning the blade and ensuring a smooth and efficient cutting process. In the cleaning mechanism 5, the scraper 503 is installed at the lower end of the outer rack 501, and the outer rack 501 is meshed with the inner rack 412 through the meshing roller 504. The scraper 503 is able to slide up and down, and is always in close contact with the lower side surface of the cutting blade 413 through the spring structure 506, ensuring that the conductive foam after cutting remains on the surface of the conveying roller 206 for conveying. This design effectively avoids the adhesion problem of the coating material 304 during the cutting process, thereby improving production efficiency and product quality. The entire device realizes efficient and automatic coating and cutting of the conductive foam through the coordinated work of the four main mechanisms of conveying, coating, cutting and cleaning, thereby significantly improving production efficiency and product quality.
