[0002] After aluminum strip is cast, it needs to be sprayed to improve its surface properties such as gloss and scratch resistance. For example, Chinese patent CN219400703U provides a spraying device for producing aluminum strip, including a box body. A through groove is provided in the middle of both sides of the box body. Two guide rods are fixed to the inner walls of both sides of the back of the box body. A fixing plate is fixed to one end of each of the four guide rods. Sliding holes are provided in the inner walls of the four fixing plates. Guide wheels are slidably connected to the inner walls of the four sliding holes. Return springs are fixed to the top of the inner walls of two of the sliding holes and the bottom of the inner walls of the other two sliding holes. One end of each of the four return springs is fixedly connected to one of the four guide wheels. A moving component is provided at the top of the box body. A drying component is provided on the inner wall of one side of the front of the box body.

Multiple connecting pipes are connected around the side of the branch pipe, and valves are disposed on the connecting pipes. U-shaped pipes are connected to the connecting pipes, and each U-shaped pipe is provided with a different number of nozzles. A flexible hose connector is connected to the main pipe. During operation, the aluminum sheet / strip passes through the top of the support frame and through the middle of the U-shaped pipe (the valve on the U-shaped pipe is open, and the valves on other U-shaped pipes are closed), so that nozzles are distributed above and below it. Depending on the width of the aluminum sheet / strip, the branch pipe is rotated to select a U-shaped pipe with a different number of nozzles to ensure a moderate spraying range, preventing excessive spraying and waste of spraying liquid, thus saving production costs.
