Description

Technical Field

[0001] The utility model belongs to the technical field of steel strip processing equipment, and in particular relates to a steel strip anti-shake device and a galvanizing machine. Background Art

[0002] Steel is easy to rust in air and water, while the corrosion rate of zinc in the atmosphere is only 1 / 15 of that of steel in the atmosphere. Galvanized steel sheets are protected from corrosion by a fine zinc coating. During the continuous production of aluminum-magnesium-zinc plating, the steel strip will be suspended for a distance on the turning roller at the top of the tower when it comes out of the zinc pot and enters the cooling tower. At present, the steel strip will be purged by the air knife and the quick cooling fan when it is plating the zinc layer of magnesium-aluminum-zinc. Since the steel strip is in a suspended state and has no tension, it will inevitably shake greatly during the blowing. When the steel strip shakes, the air knife cannot stably control the galvanizing operation, resulting in uneven galvanizing. Since the coating out of the zinc pot is not solidified, the shaking steel strip will be scratched by the air knife when it touches the air knife, which seriously affects the quality of the product.

[0003] There are studies on the problem of steel strip shaking in the prior art, such as patent application CN219233524U - a steel strip hot rolling feeding anti-shake mechanism, which prevents the steel strip from shaking by cooperating with the straightening component and the anti-shake component, solving the current problem of steel strip shaking during feeding. However, the existing anti-shake mechanism can only ensure the shaking of the steel strip feeding, but it is difficult to effectively suppress the shaking of the steel strip when it is galvanized by the air knife and the fast cooling fan. The galvanizing will still be uneven, and the surface will be scratched when it hits the air knife, thereby affecting the effect and quality of the galvanizing of the steel strip. Therefore, a new technical solution is needed to solve the above technical problems. Utility Model Content

[0026] The end of the guide rod 301 passes through the guide sleeve 302 and extends to be fixed on the side end of the magnet block 2. The guide rod 301 is directed and moved on the mounting seat 4 through the guide sleeve 302, the magnet block 2, the travel screw 7, the transmission shaft 6 and the servo motor 5.

[0027] See also Figure 1-Figure 2 and Figure 4-Figure 5One end of the travel screw rod 7 horizontally penetrates the transmission shaft 6 and is connected to the transmission shaft 6 in a spiral manner through the servo motor 5, and the other end of the travel screw rod 7 penetrates the mounting seat 4 and is fixedly connected to the middle part of the side of the magnet block 2;

[0028] The magnet block 2 is horizontally moved on the mounting seat 4 through the guide member 3 (the guide member 3 includes a guide rod 301 and a guide sleeve 302), a travel screw rod 7, a transmission shaft 6 and a servo motor 5;

[0029] The two magnet blocks 2 are magnet A201 and magnet B202, and magnet B202 and magnet A201 are arranged on both sides of the steel strip 1 opposite to each other;
