Description

Technical Field

[0001] The utility model is applicable to the technical field of cleaning aluminum plate strip foil after cold rolling, and particularly relates to a surface oil removal device for aluminum plate strip foil after cold rolling. Background Art

[0002] At present, aluminum sheet, strip and foil refers to aluminum processed products obtained through cold rolling and deformation, and is the main product type in the aluminum rolling industry. After the cold rolling of the aluminum sheet, strip and foil is completed, a large amount of grease will adhere to its surface. The presence of grease will seriously affect the surface treatment effect of the aluminum plate, such as anodizing, passivation, etc., so it must be thoroughly removed.

[0003] However, when degreasing the surface of cold-rolled aluminum foil, the aluminum foil is immersed in a degreasing agent to remove the oil stains. However, when cleaning the aluminum foil surface, the aluminum foil is limited by the fixed size of the immersion tank, and the aluminum foil cannot fully contact the degreasing agent, which in turn affects the cleaning and degreasing quality of the aluminum foil surface. Therefore, we propose a degreasing device for the surface of cold-rolled aluminum foil. Utility Model Content

[0004] The main purpose of the utility model is to provide a surface oil removal device for aluminum plates, strips and foils after cold rolling, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] Both ends of the inner side of the cleaning pool are vertically fixed with fixed frames, and the number of fixed frames is four. A transmission frame is fixedly installed on the outer side of the top of each two groups of fixed frames. An adjustment mechanism is provided inside each of the fixed frames. A synchronization mechanism is provided inside each of the transmission frames, and the synchronization mechanism and the adjustment mechanism are transmission-connected.

[0008] A sliding plate is slidably installed on the outside of each fixed frame, and the adjustment mechanism is transmission-connected to the outside of the sliding plate. A rotating rod is rotatably installed between the sides of each two groups of sliding plates through bearings, and a pressing roller is fixedly sleeved on the middle end surface of each rotating rod.

[0009] By adopting the above technical solution, the vertical position of the pressure roller inside the cleaning pool can be adjusted through the mutual cooperation of the synchronization mechanism and the adjustment mechanism, so that the two groups of pressure rollers can be set up and down inside the cleaning pool. The aluminum plate and foil to be cleaned can enter from the bottom of the left pressure roller and pass out from the top of the right pressure roller, thereby increasing the immersion time of the aluminum plate and foil in the cleaning pool, thereby increasing the contact between the aluminum plate and foil and the degreaser inside the cleaning pool, thereby ensuring the quality of cleaning the oil stains on the surface of the aluminum plate and foil.

[0011] By adopting the above technical solution, through the rotation transmission action of the lifting sleeve by the rotating screw and the position adjustment processing of the lifting sleeve on the pressure roller, the two sets of pressure rollers can be set up and down inside the cleaning pool. The aluminum plate and foil to be cleaned can pass through the bottom of the left pressure roller and pass through the top of the right pressure roller, thereby increasing the soaking time of the aluminum plate and foil in the cleaning pool.

[0012] As an optional solution to the technical solution of the present application, the synchronization mechanism includes a transmission sprocket, a follower sprocket and a transmission chain. Connecting rods are installed on both sides of the interior of each transmission frame for vertical rotation through bearings, and the bottom of the connecting rod and the top surface of the rotating screw are fixedly connected. The middle end surface of each connecting rod is fixedly sleeved with a follower sprocket. The middle end of the inner side of each transmission frame is vertically rotated by bearings. The middle end surface of each transmission rod is fixedly sleeved with a transmission sprocket, and a transmission chain is meshed and sleeved between the outer sides of the transmission sprocket and the follower sprocket.

[0013] By adopting the above technical solution, the two sets of connecting rods can drive the rotating screw rods thereunder to rotate synchronously and in the same direction through the meshing transmission action of the transmission chain on the transmission sprocket and the follower sprocket.

[0014] As an optional solution of the technical scheme of the present application, the cleaning mechanism comprises a scraping plate, an installation frame is fixedly installed between the top portions of the two groups of fixing frames, an adjusting bolt is vertically screwed at the middle end of the installation frame, an activity plate is rotatably installed at the bottom of the adjusting bolt through a bearing, the scraping plate is fixedly installed at the bottom surface of the activity plate and located above the outer side of the guide roller, guide rods are vertically and fixedly installed at the top portions of the two sides of the activity plate, limit grooves are formed at the top portions of the two sides of the installation frame, and the guide rods are slidingly inserted into the limit grooves.
