A lifting frame 2 is movably mounted on the mold 1. The lifting frames 2 are opposite to each other and lift the aluminum foam upward. A main roller 3, a slave roller 4, and a guide roller 5 are rotatably connected to the lifting frame 2. The main roller 3, the slave roller 4, and the guide roller 5 are arranged in a triangular distribution. A steel belt 6 is movably mounted on the main roller 3, the slave roller 4, and the guide roller 5, so that the steel belt 6 can drive the main roller 3, the slave roller 4, and the guide roller 5 to rotate. A scraper assembly 7 is movably installed on the lifting frame 2 at one side of the guide roller 5. The scraper assembly 7 scrapes off the steel strip 6 rotating on the guide roller 5. A baffle 102 is fixedly connected in the middle of the mold 1, which divides the mold 1 into a liquid storage tank and a foaming tank. A conveying outlet 101 is provided on the mold 1 so that the foamed aluminum foam can be easily moved out of the conveying outlet 101. The lifting frame 2 is located on both sides of the conveying outlet 101. The main roller 3 and the secondary roller 4 are located at the upper and lower parts of the lifting frame 2, respectively. The guide roller 5 is located on the side of the lifting frame 2. A drive motor 301 is fixedly connected to the lifting frame 2. The drive motor 301 drives the main roller 3, so that the drive motor 301 drives the main roller 3 to rotate, thereby driving the steel belt 6 to rotate.

[0032] A water-cooled box 14 is fixedly connected to the inner side of the lifting frame 2. The water-cooled box 14 is slidably connected to the steel strip 6 and cools the steel strip 6 and the foamed aluminum on the side. Water inlet pipes 1401 and 1402 are fixedly connected to both sides of the water-cooled box 14. The water inlet pipes 1401 and 1402 pass through the corresponding plates on the lifting frame 2 and extend to the outside, facilitating the connection of the water-cooled box 14 to external pipes via the water inlet pipes 1401 and 1402. A support base 13 is fixedly connected to the mold 1, and a cylinder 12 is fixedly connected to the support base 13. The output shaft is fixedly connected to the lifting frame 2, and the cylinder 12 drives the lifting frame 2 to slide on the mold 1, so that the lifting frames 2 can move towards each other or away from each other. Limiting plates 501 are fixedly connected to both sides of the guide roller 5. The steel strip 6 on the guide roller 5 is located between the limiting plates 501. The limiting plates 501 restrict the steel strip 6 so that the steel strip 6 does not deflect when rotating. A leveling plate 10 is fixedly connected to the lower part of the lifting frame 2. A heater 11 is fixedly connected to the side of the leveling plate 10. An electric heating wire is fixedly connected inside the heater 11. After the leveling plate 10 is heated, it compresses the aluminum foam.

[0033] The scraper assembly 7 includes a mounting bracket 701, a slide rod 702, a mounting base 703, and a first spring 707. The mounting bracket 701 is fixedly connected to both sides of the lifting frame 2. The slide rod 702 is fixedly connected to the mounting bracket 701 and guides the first spring 707, causing the first spring 707 to compress or release along the direction of the slide rod 702. The two ends of the mounting base 703 are slidably connected to the slide rod 702. The first spring 707 is movably mounted on the slide rod 702 and is located on the side of the mounting bracket 701. The first spring 707 pushes the mounting base 703 to move to one side.

[0034] The scraper assembly 7 also includes a mounting groove 706, a scraper 704, a first fixing bolt 705, a collection box 708, and a second fixing bolt 709. The mounting groove 706 is formed on the mounting base 703. The scraper 704 is fixedly connected to the mounting groove 706 by the first fixing bolt 705, and the cutting edge of the scraper 704 is slidably connected to the steel strip 6. The mounting groove 706 provides a position for the installation of the scraper 704. The collection box 708 is fixedly connected to the lower part of the mounting base 703 by the second fixing bolt 709, so that the collection box 708 collects the debris scraped off by the scraper 704.

[0035] The steel belt 6 rotates on the main roller 3, the secondary roller 4, and the guide roller 5. When the steel belt 6 rotates on the guide roller 5, the compressed No. 1 spring 707 pushes the mounting base 703 to move to the side, so that the scraper 704 on the mounting base 703 fits tightly against the scraper 704, scraping off the debris. The scraped debris then slides into the collection box 708 under the action of gravity, making it easy to collect the debris scraped off the steel belt 6.

[0036] A grinding component 8 is movably installed on the lifting frame 2 on the other side of the guide roller 5. The grinding component 8 grinds the scraped steel strip 6 to further remove debris. The grinding assembly 8 includes a lifting plate 801, a grinding stone 802, rubber wiping heads 803, a connecting rod 804, and a first connecting plate 805. The lifting plate 801 is located on the side of the steel belt 6 and inside the lifting frame 2. The grinding stone 802 and the rubber wiping heads 803 are fixedly connected to the lifting plate 801. The grinding stone 802 grinds the steel belt 6 to remove residual solidified debris. The rubber wiping heads 803 are located behind the grinding stone 802 and are arranged in a straight line at equal intervals. The rubber wiping heads 803 wipe the steel belt 6 to remove powder and other impurities generated during grinding. The connecting rod 804 is fixedly connected to both sides of the lifting plate 801. The first connecting plate 805 is located on both sides of the lifting frame 2 and is fixedly connected to the connecting rod 804 corresponding to the side of the lifting plate 801. The first connecting plate 805 drives the lifting plate 801 to rise and fall.

[0037] The grinding assembly 8 also includes a second connecting plate 806, a connecting groove 807, a second spring 808, and a first base plate 809. The second connecting plate 806 is fixedly connected to both sides of the lifting frame 2, and the first base plate 809 is fixedly connected to both ends of the second spring 808. The second spring 808 is located between the first connecting plate 805 and the second connecting plate 806. The second spring 808 is fixedly connected to the first connecting plate 805 and the second connecting plate 806 respectively through the first base plate 809.

[0038] After being scraped by the scraper 704, the steel strip 6 moves downward, allowing it to grind against the grinding stone 802 on the lifting plate 801. A first connecting plate 805 is fixedly connected to both sides of the lifting plate 801. A compressed second spring 808 pushes the first connecting plate 805 upward, causing it to move upward and tightly adhere to the grinding stone 802, thus grinding the steel strip 6 and removing any remaining aluminum foam residue. Then, a rubber wiping head 803 behind the grinding stone 802 wipes the steel strip 6, removing powder and other impurities generated during grinding.

[0039] A coating assembly 9 is movably mounted on the lifting frame 2 at a position below the roller 4. The coating assembly 9 coats the steel strip 6 that rotates from the roller 4.

[0040] The paint assembly 9 includes a support plate 901, a paint box 902, a third spring 903, and a second base plate 904. The support plate 901 is fixedly connected to the lower part of the lifting frame 2. The paint box 902 is located above the support plate 901. The overall weight of the paint box 902 and the paint inside it compresses the third spring 903 downward, thereby reducing the height of the paint box 902. The paint box 902 slides downward on the roller box 905. The two ends of the third spring 903 are fixedly connected to the second base plate 904. The third spring 903 is fixedly connected to the support plate 901 and the paint box 902 through the second base plate 904. The third spring 903 is located between the support plate 901 and the paint box 902.

[0041] The coating assembly 9 also includes a roller box 905, ear plates 906, a feed hole 907, and a coating roller 908. The ear plates 906 are fixedly connected to both sides of the roller box 905. The roller box 905 is fixedly connected to the lifting frame 2 via the ear plates 906. The coating roller 908 is rotatably connected to the lower part of the lifting frame 2, and the roller of the coating roller 908 is movably installed inside the roller box 905. The lower part of the roller of the coating roller 908 contacts the coating material, and after rotating to the upper position, it contacts the steel strip 6, thereby coating the steel strip 6. The feed hole 907 is opened on the bottom surface of the roller box 905. The coating material in the coating box 902 enters the roller box 905 through the feed hole 907. The roller of the coating roller 908 coats the steel strip 6 from the roller 4. The coating material in the coating box 902 enters the roller box 905 through the feed hole 907, which facilitates the contact between the coating rollers 908.

[0042] After the steel strip 6 is polished by the grinding stone 802, the powder and other impurities on it are wiped off by the rubber wiping head 803. Then the steel strip 6 rotates onto the roller 4. The coating roller 908 is rotatably connected to the steel strip 6, so that the coating roller 908 can easily apply coating to the steel strip 6 and attach a layer of release agent to the steel strip 6, so that the foam aluminum can be easily separated from the steel strip 6 later. The coating box 902 is pushed by the compressed No. 3 spring 903. When the coating in the coating box 902 gradually decreases, the overall weight of the coating box 902 decreases. The No. 3 spring 903 pushes the coating box 902 upward, thereby maintaining the amount of coating in the roller box 905 and extending the service life of the coating roller 908.

[0043] It should be noted that the present invention is a processing method for preparing high-strength aluminum foam based on the air blowing method. In the present invention, the inner baffle 102 of the mold 1 divides it into two parts, one side is a liquid storage tank and the other side is a foaming tank. A conveying outlet 101 is provided at the upper position of the foaming tank. The bubbles in the foaming tank are generated by the air blowing device, adsorb silicon carbide particles in the melt, rise to the top of the foaming tank and accumulate, and are discharged upward through the conveying outlet 101. Lifting frames 2 are provided on both sides of the conveying outlet 101 to lift the aluminum foam. The aluminum foam discharged from the conveying outlet 101 is located between the straightening plates 10. The heater 11 is equipped with an electric heating wire to heat the straightening plates 10. The cylinder 12 pushes the lifting frame 2 and the straightening plates 10 inside it to move towards each other, compressing the molten aluminum foam in the middle position. The shrinkage of the straightening plates 10 can compress 1 to 2 bubbles on the surface of the molten aluminum foam, while the inside still maintains the complete bubble morphology. The drive motor 301 drives the main roller 3 to rotate, which causes the steel strip 6 on the main roller 3 to rotate. The steel strip 6 drives the guide roller 5 and the driven roller 4 to rotate. The aluminum foam is located between the steel strips 6, so that the steel strips 6 on the main roller 3 and the driven roller 4 lift the aluminum foam upward. A water-cooled box 14 is installed on the inner side of the lifting frame 2. Cold water enters the water-cooled box 14 from the inlet pipe 1401 and then exits from the outlet pipe 1402 to cool the steel strip 6 and the foamed aluminum on the side of the steel strip 6. After the steel belt 6 moves from the main roller 3 to the guide roller 5, the scraper 704 on its scraper assembly 7 scrapes off the residual aluminum foam debris. The scraper 704 is located on the mounting base 703 and moves together with the mounting base 703. The compressed first spring 707 pushes the mounting base 703 to move, so that the scraper 704 is in close contact with the steel belt 6, making it easy to scrape off the debris. The scraped debris enters the collection box 708 below by gravity. The collection box 708 can be disassembled and installed by the second fixing bolt 709, making it easy to clean the debris in the collection box 708. After the steel strip 6 is removed from the guide roller 5, it moves downward and rubs against the grinding plate 802 of the grinding assembly 8 to grind away the solidified debris remaining on it. The steel strip 6 is then wiped by the rubber wiping head 803 to remove the powder. The compressed second spring 808 pushes the first connecting plate 805 upward, causing the lifting plate 801 to move the grinding plate 802 upward and make close contact with the steel strip 6, making it easier to remove the solidified debris. The rubber wiping head 803 at the rear of the lifting plate 801 wipes the ground steel strip 6 to remove the powder generated during grinding, improve the cleanliness of the steel strip 6, and prepare it for subsequent application of the release agent. The steel strip 6 moves onto the roller 4 and is coated with a release agent by the coating roller 908 on the coating assembly 9. The steel strip 6 and the coating roller 908 are rotatably connected to each other. The coating roller 908 picks up the coating from the roller box 905 at the lower position and then rotates upward to contact the steel strip 6, so that a layer of release agent is attached to the surface of the steel strip 6, which facilitates the subsequent separation of the foamed aluminum from the steel strip 6 and reduces the debris on it.
