The surface of the cold rolled strip is clean and bright, and it is easy to be coated and plated. It is mainly used in automobiles, printed iron drums, construction, building materials, bicycles and other industries. It is also the best material for producing organic coated steel plates.

[0003] During the processing of cold-rolled steel strip, it needs to be washed, pickled, and then washed again. After searching, it is found that a pickling tank for cold-rolled steel strip production is disclosed in Chinese patent literature [Application No.: 2016213586538; Publication No.: CN206502870U]. The structure of this pickling tank is too simple, and it can only achieve simple pickling of cold-rolled steel strip, and it is impossible to brush off the dirt attached to its surface. At the same time, the acid on the surface of the cold-rolled steel strip will also enter the subsequent water washing tank in large quantities. Therefore, it is necessary to design a pickling machine for cold-rolled steel strip. Summary of the invention

[0006] The upper movable beam is also provided with a scraper bar, and the scraper bar is arranged behind the first brush bar.

[0007] The scraper strip is V-shaped.

[0008] The locking screw 1 and the locking screw 2 are hand screws.

[0009] A handle is also installed on the connecting arm.

[0010] Compared with the prior art, the pickling machine for cold-rolled strip steel has the following advantages:

[0011] In the utility model, brush strips one and two with a certain range of movement are provided, so that the upper and lower surfaces of the cold-rolled steel strip can be cleaned. At the same time, the scraper strip can be used to scrape off the acid on the upper surface of the cold-rolled steel strip after pickling, thereby reducing the amount of acid entering the subsequent water washing tank.
