[0024] The frame body 1 is provided with a liquid discharge pipe 9, a smoke pipe 10, a cold water pipe 11, and an operation channel 12 that cooperates with the cold water pipe 11;

[0025] The frame body 1 is slidably connected with an adjustment bracket 13, which is driven by a first power device. The adjustment bracket 13 is vertically slidably connected with a vertical auxiliary plate 14, which is driven by a second power device. The vertical auxiliary plate 14 is slidably connected with two groups of clamps 15 at intervals, and the two groups of clamps 15 are driven by a third power device.

[0026] The frame body 1 is provided with a roller bracket 16, and the roller bracket 16 is provided with a fixing bracket 17 corresponding to the clamp 15, and the roller bracket 16 is rotatably connected with a material rolling drum 18, and the material rolling drum 18 is provided with arrays of liquid inlet holes 19 at intervals, and the material rolling drum 18 is driven by a fourth power device;

[0027] The frame is provided with a primary deplating tank 2, a secondary deplating tank 3, a tertiary deplating tank 4, a primary water washing tank 5, a secondary water washing tank 6, a tertiary water washing tank 7 and a feed tank 8 in sequence;

[0028] The liquid discharge pipe 9, the cold water pipe 11 and the operating channel 12 are all located at the bottom of the frame body 1, and the cold water pipe 11 and the operating channel 12 are connected;

[0029] The first power device includes a bidirectional motor 20 provided on the adjustment bracket 13, the output shaft of the bidirectional motor 20 is provided with a gear 21, the frame body 1 is provided with a rack 22 matched with the gear 21, and the bidirectional motor 20 is electrically connected to the controller;

[0030] The second power device includes a lifting motor 23 and a lifting rotating shaft 24 provided on the adjusting bracket 13, the lifting rotating shaft 24 is rotatably connected to the adjusting bracket 13, two sets of pulleys 25 are provided on the lifting rotating shaft 24, and both sets of pulleys 25 are provided with lifting belts 26, one end of the lifting belt 26 is connected to the vertical auxiliary plate 14, and the lifting motor 23 is electrically connected to the controller;
