Description

Technical Field

[0002] Metal sheets are widely used in industrial production, but due to the oxidation and rust problems existing in their raw materials and production processes, pickling treatment is required to achieve a clean and smooth surface effect. The metal sheet pickling device is a device used to clean the surface of metal sheets. It is mainly used to remove oxide scale, rust, oil stains and other pollutants on the metal surface. This equipment is mainly used for the surface treatment of metals such as steel, aluminum, and copper, and is widely used in automobile manufacturing, electronics, and manufacturing industries.

[0003] The pickling device usually includes multiple components, such as loading and unloading components, conveying components, acid bath spray components and water washing components. Among them, the loading and unloading components play a vital role in the entire pickling device.

[0039] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0040] When in use, add a proper amount of pickling liquid to the inner cavity of the pickling liquid box 4, start the first conveying platform 1, and use the first conveying platform 1 to drive the metal sheet 3 to move. When the metal sheet 3 moves to the top of the first conveying roller 513, use the infrared sensor 58 to monitor that the metal sheet 3 moves to the top of the first conveying roller 513, and continue to use the first conveying platform 1 to drive the metal sheet 3 to move. At the same time, use the infrared sensor 58 to monitor the metal sheet 3 in real time until the metal sheet 3 completely moves to the top of the first conveying roller 513. The infrared sensor 58 can detect that the metal sheet 3 is completely separated from the top of the first conveying platform 1, and the second hydraulic cylinder 59 is started. The second hydraulic cylinder 59 drives the pressure plate 61 to move downward, and the pressure plate 61 moves downward. During the movement, the second conveying roller 65, the second brush roller 66, the second sprocket 69 and the fifth sprocket 619 are simultaneously driven to move downward. The downward movement of the second sprocket 69 and the fifth sprocket 619 can stretch the two second chains 618 to move downward. At the same time, the second chain 618 is used to pull the fourth sprocket 617 to drive the telescopic rod 614 to move inward, and stretch the second spring 615 to elastically deform. The pressing plate 61 moves downward until the second conveying roller 65 contacts the metal sheet 3. The second hydraulic cylinder 59 continues to drive the pressing plate 61 to move downward, and the second conveying roller 65 can be used to press the metal sheet 3 to drive the first supporting plate 511 to move downward, until the first supporting plate 511 and the metal sheet 3 are pressed into the pickling liquid in the pickling liquid tank 4 by the pressing plate 61, and the pickling liquid tank 4 is used to press the first supporting plate 511 and the metal sheet 3. The metal sheet 3 is pickled with liquid, and the motor 610 located on the front side is started at this time. The rotation of the output end of the motor 610 can cause the plurality of second brush rollers 66 to rotate through the cooperation between the third sprocket 612, the fourth sprocket 617, the second sprocket 69, the second chain 618, the first sprocket 67 and the first chain 68 matched therewith, so that the second brush rollers 66 are used to brush the upper surface of the metal sheet 3. At the same time, the motor 610 located on the rear side is started, and the output end of the motor 610 located on the rear side is used to rotate counterclockwise and clockwise reciprocatingly, and the cooperation between the third sprocket 612, the fourth sprocket 617, the second sprocket 69, the second chain 618, the fifth sprocket 619 and the third chain 620 matched therewith can cause the plurality of first brush rollers 66 to rotate. The two conveying rollers 65 rotate clockwise and counterclockwise, thereby driving the metal sheet 3 to move back and forth left and right, so that the second brush roller 66 is used to scrub the lower surface of the metal sheet 3 to enhance the pickling effect. The first brush roller 514 and the second brush roller 66 scrub the surface of the metal sheet 3 to remove stubborn dirt and oxides on the metal surface, and can promote the diffusion and penetration of the pickling liquid on the metal surface, thereby improving the pickling efficiency. After the pickling of the metal sheet 3 is completed, the two motors 610 are turned off, and the second hydraulic cylinder 59 is started to drive the pressure plate 61 to move upward, thereby releasing the squeezing of the first support plate 511, and the first support plate 511 and the metal sheet 3 are pulled upward under the elastic force of the first spring 512 until they return to the initial position.Start the first hydraulic cylinder 56, and use the first hydraulic cylinder 56 to push the rack 57 to move, so that the rack 57 causes the gear 55 to drive the rotating rod 53 to rotate, and the rotating rod 53 drives the baffle 54 to rotate until the baffle 54 rotates to the bottom of the first support plate 511, and the baffle 54 is used to support the first support plate 511, and the second hydraulic cylinder 59 is started to push the pressure plate 61 to move downward until the second brush roller 66 is firmly attached to the metal sheet 3, and the motor 610 located at the rear side is started, so as to cause the second conveying rollers 65 to rotate counterclockwise, thereby causing the metal sheet 3 to move to the right until the metal sheet 3 moves to the top of the second conveying platform 2, and the second conveying platform 2 is used to convey the metal sheet 3 to move for subsequent processing, and the device can be restored to the initial state by moving in the opposite direction to the above. Position, repeat the above actions to complete the repeated processing of the metal sheet 3. The device adopts a fully automatic loading and unloading component, which can reduce manual operation and is easy to operate. The metal sheet 3 can be quickly loaded into the pickling frame and automatically removed after the pickling is completed. There is no need for manual loading and unloading and removing of the metal sheet 3, which avoids the harm of the operator to the pickling liquid, improves the safety of operation, and improves production efficiency. In addition, the device can wash the surface of the metal sheet 3 while pickling the metal sheet 3, which helps to remove stubborn dirt and oxides on the metal surface, and can promote the diffusion and penetration of the pickling liquid on the metal surface, improve the pickling effect, reduce the necessity of multiple pickling, reduce the amount of acid used, save resources, and thus also have certain environmental benefits.
