[0002] Steel plate is the raw material for manufacturing the barrel body, top cover and bottom cover of steel drum. The traditional way of processing steel plate is to cut, weld and stamp first, and then perform phosphating cleaning, which results in that only the barrel body can be cleaned during phosphating cleaning, and the inside of the steel drum cannot be cleaned at the same time. Moreover, the cleaning can only be performed individually, and the cleaning efficiency is low. Therefore, in order to solve the above defects, a phosphating cleaning device for steel plate can be designed. The phosphating cleaning device first performs phosphating cleaning on the steel plate, so that the steel plate in each subsequent process (cutting, welding, stamping, etc.) is clean.

The cleaning of multiple steps combined can significantly improve the cleanliness after cleaning. Two groups of driving components are set, so that the first group of driving components can be realized. After taking materials from the feeding mechanism and the cleaning box one, it slides close to the discharging mechanism, and the steel plates on the two taking plates are put into the cleaning box one and the cleaning box two again. Then, the steel plates in the feeding mechanism are moved for the first cleaning, and the steel plates after the first cleaning are moved just for the second cleaning; when the taking plates of the first group of driving components are in the feeding mechanism and the cleaning box one, at the same time, the taking plates of the second group of driving components are located in the cleaning box two and the cleaning box three.

The short rod is clamped in the chute 1, and the chute 1 is divided into a descending section, a horizontal section 1, an ascending section and a horizontal section 2. Therefore, when the driving cylinder rotates until the short rod is located in the descending section, the driving rod, i.e., the material taking plate, is driven to descend and go deep into the cleaning box to take the material. Then the short rod is located in the horizontal section 1 and is immersed in the cleaning box. Then, the short rod is located in the ascending section and is lifted up from the cleaning box. Finally, the short rod is located in the horizontal section 2. At this time, the toothed part of the driving gear is externally meshed with the rack 1 on one side.
