DETAILED DESCRIPTION

[0026] The embodiment of the present invention provides an alkaline etching device for processing aluminum alloy plates, such as Figure 1-6 As shown, the metal sheet is alkali-etched, comprising a liquid reservoir 1, a frame 2 is suspended in the liquid reservoir 1, two movable plates 3 are arranged symmetrically in the frame 2, a plurality of brush rollers 4 are arranged between the two movable plates 3, the metal sheet is between two adjacent brush rollers 4, and the surface of the metal sheet is cleaned of oxides by rotating the brush rollers 4. The liquid reservoir 1 is originally equipped with a heating system, which is not described in detail because it is a prior art.

[0027] A vertical extension rod 5 is welded at the bottom of the movable plate 3. The extension rod 5 is located between two adjacent metal plates. An oxide detection component is connected between two extension rods 5 in the same row to sense whether oxides are attached to the front and rear surfaces of the metal plates.

[0028] The oxide detection assembly includes two thin steel wires 53, which are in contact with the surface of the metal plate. The movable plate 3 can move up and down. During the movement of the movable plate 3, the thin steel wires 53 scrape off the stubborn oxides.

[0029] The oxide detection assembly also includes two support rods 51, a small spring 52 and a force measuring unit 54. The force measuring unit 54 is fixedly installed at the upper end of the extension rod 5. One end of the support rod 51 is hinged to the rod body of the extension rod 5. The two support rods 51 are flush with each other. One end of the support rod 51 away from the extension rod 5 is welded to a thin steel wire 53. The thin steel wire 53 is in a taut state. The small spring 52 is welded between the two support rods 51.

[0030] The elastic potential energy of the small spring 52 causes the two support rods 51 to move away from each other, thereby causing the thin steel wire 53 to contact the metal plate.

[0031] The support rod 51 carries a counterweight. If the oxide is not stubbornly attached, the thin steel wire 53 can easily scrape the oxide off. The support rod 51 rises slightly but does not contact the force measuring unit 54.

[0032] During operation, the movable plate 3 slowly descends to drive the thin steel wire 53 to move. When encountering stubborn oxides, the movement of the thin steel wire 53 is hindered, and the support rod 51 is pulled up and always exerts pressure on the force measuring unit 54. The value measured by the force measuring unit 54 reaches the preset range and feeds back the information to the external computer terminal.

[0033] A groove is provided at the bottom of the movable plate 3, and the groove is aligned with the metal sheet. A flap 31 is hinged at the groove. A striking part 32 is fixedly installed at the lower end of the flap 31, and the striking part 32 is used to touch the metal sheet. A magnet 33 is fixedly installed on the side of the flap 31 away from the metal sheet. A large spring 34 is welded between the flap 31 and the movable plate 3, and multiple electromagnet units 11 are fixedly installed at equal distances on the left and right sides of the liquid storage tank 1.

[0034] The surfaces of the flap 31, the impact part 32, the magnet 33, the spring and other components are all coated with a corrosion-resistant layer.

[0035] When working, the force measuring unit 54 feeds back information to the external computer terminal, the electromagnet unit 11 is energized to generate a magnetic field, and when the magnet 33 passes through the electromagnet unit 11, the flap 31 deflects away from the metal sheet, and the large spring 34 is squeezed. When the magnet 33 is away from the electromagnet unit 11, the large spring 34 is reset. So that every time the electromagnet unit of the movable plate 3 hits the metal sheet, the impact part 32 hits the metal sheet. The thin steel wire 53 is assisted by vibration to remove the oxide and shake it off.

[0036] A vertical screw rod 26 is pivotally connected in the frame 2 , and the screw rod 26 is driven to rotate by a motor. The movable plate 3 is provided with a screw hole 35 adapted to the screw rod 26 , and the movable plate 3 extends the screw rod 26 to move up and down.

[0037] The top of the frame 2 is threadedly fixed with a slide bar 22, which is slidably matched with a slide seat 23, and the bottom of the slide seat 23 is connected with a scraper 24, which is used to contact the top of the metal sheet. The scraper 24 moves back and forth to clean the oxide on the top of the metal sheet.

[0038] A vertical electric push rod 25 is fixedly installed around the top of the frame 2 to achieve the purpose of lifting the frame 2.

[0039] A motor 6 is fixedly mounted on the end of the brush roller 4 , and the motor 6 is fixedly mounted together with the movable plate 3 .

[0040] A leak hole 21 is provided at the bottom of the frame 2, and a mesh cover 7 is arranged at the bottom of the frame 2. A spiral blade 71 driven by a motor is arranged inside the mesh cover 7. The spiral blade 71 is used to stir the liquid inside the liquid storage tank 1, so that the temperature can be evenly distributed during the heating process of the alkali pool.

[0041] In summary, the alkaline etching device for processing aluminum alloy plates has a frame 2 set up in a liquid storage tank 1, and a pair of movable plates 3 that can move up and down are arranged in the frame 2, and the movable plates 3 are installed with multiple brush rollers 4. A thin steel wire 53 is arranged under the movable plate 3, and the oxides on the surface of the metal plate are removed by the cooperation of the brush roller 4 and the thin steel wire 53. By setting up a flap 31, a collision part 32, a magnet 33, a large spring 34 and an electromagnet unit 11, the metal plate is knocked, and the oxides on the metal plate are shaken off by vibration, which plays a role of auxiliary cleaning and enhances the oxide cleaning effect. It prevents oxides from adhering to the surface of the aluminum alloy plate and affecting the continuous reaction.
