[0001] The utility model relates to an aluminum plate spraying device, in particular to a chromium-free passivating agent spraying device for the aluminum plate, belonging to the technical field of aluminum plate spraying processing. Background Art

[0002] Chromium-free passivation liquid is a chromium-free passivation liquid, which is mainly used for the passivation of metal workpieces such as aluminum plates. Its main function is to prevent rust on the surface of metal workpieces. After the production of aluminum plates is completed, the chromium-free passivation agent is generally sprayed on its surface by spraying to improve its anti-rust and anti-corrosion properties.

[0003] When the aluminum plate is sprayed with a spray device, the part to be sprayed is clamped and fixed, and then the spraying process is carried out. During spraying, the bottom of some shapes of aluminum plates often requires secondary spraying due to placement reasons, resulting in reduced spraying efficiency; and manual flipping is required, which is very inconvenient to operate; at the same time, it cannot be drained quickly after spraying, which is easy to cause contamination by external impurities when drying, thus requiring secondary spraying, which greatly reduces work efficiency.

It should be noted that the travel distance that the second screw rod 23 drives the partition 20 to slide is sufficient for the aluminum plate clamping frame 4 holding the aluminum plate to pass through later.

[0026] A chromium-free passivating agent spraying mechanism 2 is arranged inside the processing box 1, and the chromium-free passivating agent spraying mechanism 2 includes a chromium-free passivating agent storage tank 201, a first nozzle 202 located above the interior of the processing box 1, and a plurality of second nozzles 203 located on the side of the interior of the processing box 1.
