The lower plate brushing roller 1311 and the lower plate synchronous roller 1312 are installed on the first fixed frame. Among them, the lower plate brushing roller 1311 includes a body and bristles provided on its surface. The body is cylindrically arranged, and the bristles are sleeved on the outside of the body. The material of the bristles can be set according to the plate to be cleaned or the effect to be achieved. For example: steel bristles, cotton and linen bristles. The lower plate brushing roller 1311 and the lower plate synchronous roller 1312 are arranged at an upper and lower interval, that is, the lower plate brushing roller 1311 is below the lower plate synchronous roller 1312 to brush the lower plate surface of the plate. Similarly, the upper plate brushing member includes an upper plate brushing roller 1321 and an upper plate synchronous roller 1322, and its structure can refer to the structure of the lower plate brushing member.

Since the plate cleaning device 100 adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated one by one here.

[0041] Specifically, for the specific structure of the conveying belt 20, a commercially available conveyor belt can be referred to. The conveying belt 20 extends in the horizontal direction for conveying plates, that is, the extension direction of the conveying belt 20 is the direction of plate conveyance. The caustic washing device 30, the first water washing device 41, the electro-degreasing device 50, the second water washing device 42, the pickling device 60, the third water washing device 43, and the plate brushing device 10 are sequentially arranged at intervals along the extension direction of the conveying belt 20. Among them, the caustic washing device 30 includes a second fixed frame, heating pipes, and multiple caustic washing nozzles. The second fixed frame is connected to the conveying belt 20 and forms a caustic washing space. The heating pipes and multiple caustic washing nozzles are installed in the caustic washing space. The heating pipes are used to heat the plates entering the caustic washing space to accelerate the fluidity of the oil stains on the plate surface. The caustic washing nozzles are used to spray alkaline solution onto the plate surface to hydrolyze and alcoholize the oil and dirt on its surface. The electro-degreasing device 50 includes a third fixed frame, an electrolytic cell, and electrolytic electrodes. The third fixed frame is installed on the conveying belt 20, the electrolytic cell is installed on the third fixed frame, and the electrolytic electrodes are installed on the third fixed frame and correspond to the electrolytic cell.

The first water washing device 41 includes multiple spray heads, and the multiple spray heads are correspondingly installed on the conveying belt 20. When the plates pass through, clean water can be sprayed onto the plates to remove impurities and oil stains on the plate surface. The specific structures of the second water washing device 42, the pickling device 60, and the third water washing device 43 can refer to the structure of the first water washing device 41, and no redundant description will be made here. It should be noted that the spray heads of the pickling device 60 spray acidic liquid onto the plates, which can not only neutralize the residual caustic solution on the plate surface, but also slightly corrode the plate surface, thereby increasing its specific surface area.

[0042] Further, the electro-degreasing device 50 further includes a sandblasting device 70. The sandblasting device 70 includes a fourth fixed frame, multiple upper sandblasting heads, and multiple lower sandblasting heads. The fourth fixed frame is installed on the conveying belt 20.

The multiple lower sandblasting heads are located above the conveying belt 20 and are evenly spaced along its extension direction. By setting this sandblasting device 70, the surface of the plates can be polished to improve the forming quality.

[0043] Further, the plate cleaning equipment 100 further includes a fourth water washing device 44 and a high-pressure water washing device 80. The fourth water washing device 44 and the high-pressure water washing device 80 are sequentially arranged at intervals downstream of the sandblasting device 70. The specific structures of the fourth water washing device 44 and the high-pressure water washing device 80 can refer to the structure of the first water washing device 41, and no redundant description will be made here. Different from the first water washing device 41, the high-pressure water washing device 80 can accelerate the removal of the residual sand grains on the plate surface after sandblasting by increasing the shooting speed of the water flow.

[0044] Furthermore, the sheet cleaning device 100 includes a drying device 90, which includes a fifth fixed frame, a fan, and a hot air duct. The fifth fixed frame is installed downstream of the high-pressure water washing device 80 and forms a drying chamber. The fan and the hot air duct are installed in the drying chamber. The hot air duct is used to convey hot air into the drying chamber. The fan blows the water droplets on the surface of the sheet away and accelerates evaporation, and the hot air is used to accelerate the evaporation of the water droplets on the surface of the sheet. The two work together to dry the upper and lower surfaces of the sheet, thereby avoiding rust caused by water droplet residues.

[0045] The sheet cleaning device 100 of the present application automatically cleans the sheet by sequentially conveying the sheet to be cleaned to multiple devices through the conveyor belt 20. By providing an alkali washing device 30, a primary water washing device 41, an electro-degreasing device 50, a secondary water washing device 42, a pickling device 60, a tertiary water washing device 43, a sheet brushing device 10, a sandblasting device 70, a quaternary water washing device 44, a high-pressure water washing device 80, and a drying device 90, multiple cleaning and brushing operations can be performed on the sheet, and the degreasing effect on the sheet is better.

[0046] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
