Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, specifically a continuous cleaning device for high-strength galvanized steel strip. Background Technology
[0002] In the high-strength galvanized steel strip manufacturing industry, high-strength galvanized steel strips generally require cleaning during processing. Currently, the industry uses high-pressure water jet spraying to clean high-strength galvanized steel strips, that is, using high-pressure water jets to spray water to rinse the steel strips.
[0003] However, the existing equipment has the drawback that after a long period of use, the water in the cleaning tank needs to be cleaned regularly with dirt such as iron filings and impurities. The cleaning process requires stopping the machine and production to remove the dirt from the cleaning tank.
[0004] As disclosed in the high-strength galvanized steel strip continuous cleaning device with announcement number CN219401396U, the steel strip passes over the upper reversing roller on one side and then over the lower reversing roller before entering the cleaning water. Finally, it exits from the reversing roller on the other side for cleaning. During the cleaning process, the cleaning water enters the filtration equipment to filter out dirt and then flows back into the cleaning tank. The first water inlet pipe replenishes the cleaning tank with the consumed cleaning water to maintain the cleanliness and quantity of the cleaning water in the cleaning tank. The cleaning equipment is cleaned regularly to avoid downtime caused by cleaning the cleaning tank, which facilitates continuous production and improves production efficiency.
[0005] However, the device cannot tension the high-strength galvanized steel strip during use. When the tension is too low, the steel strip will wrinkle, making it difficult for the cleaning fluid to penetrate into the wrinkles and affecting the cleaning quality of the steel strip.
[0006] Therefore, we urgently need to provide a continuous cleaning device for high-strength galvanized steel strip. Utility Model Content
[0007] The purpose of this invention is to provide a continuous cleaning device for high-strength galvanized steel strip, in order to solve the problem mentioned in the background art that when the tension is too small, the steel strip will wrinkle, making it difficult for the cleaning fluid to penetrate into the wrinkles and affecting the cleaning quality of the steel strip.

[0031] Example 2:
[0032] Based on Example 1, please refer to Figures 1-4After cleaning, the steel strip has cleaning fluid adhering to its surface, which needs to be wiped off. Therefore, this device is also equipped with a wiping mechanism, which includes a fixing plate 601, a sponge wiper 602, a fixing plate 603, and a sponge wiper 604. The fixing plate 601 is fixedly installed on the front and rear sides of the upper right side of the cleaning tank 1. The sponge wiper 602 is installed on the side adjacent to the two fixing plates 601. The cleaning fluid on the surface of the high-strength galvanized steel strip is wiped off by the sponge wiper 602 and the sponge wiper 604. The fixing plate 603 is installed on the front and rear sides of the lower right side of the cleaning tank 1. The sponge wiper 604 is installed on the side adjacent to the two fixing plates 603. The sponge wiper 602 and the sponge wiper 604 are respectively installed on the fixing plate 601 and the fixing plate 603 by bolts, which facilitates the installation and removal of the sponge wiper 602 and the sponge wiper 604.
[0033] In use, one end of the high-strength galvanized steel strip is passed between the upper pressure roller 403 and the lower pressure roller 411, then through the inlet on the left side of the cleaning tank 1, then between the two guide rollers 2, then between the brush rollers 502 and 503, then between the two guide rollers 3, and finally out through the outlet. Cleaning fluid is then injected into the cleaning tank 1. As the steel strip is conveyed from left to right, the cleaning fluid washes the strip. The motor 501 drives the brush rollers 502 and 503 to rotate, brushing the steel strip. Simultaneously, the brush rollers 502 and 503 agitate the cleaning fluid, further rinsing the steel strip. To further improve the cleaning quality of the steel strip, when the steel strip tension is too low and wrinkles occur, the motor 404 is started to drive the rotating shaft 405 and the bevel gear 406 to rotate. The bevel gear 406 meshes with the bevel gear 408, causing the bevel gear 408 to drive the threaded rod 407 to rotate. When the threaded rod 407 rotates, it is threadedly connected to the moving block 410, causing the moving block 410 to drive the lower pressure roller 411 to move upward along the limit rod 409. The upper pressure roller 403 presses the steel strip, thereby increasing the tension of the steel strip. After cleaning, the steel strip is wiped by the sponge 602 and the sponge 604 to remove the cleaning liquid from the surface of the steel strip, thus completing the cleaning of the steel strip.
