[0002] The 1950mm stretch-bending straightening machine is a key equipment in the plate and strip plant. Therefore, the stretching and straightening of aluminum alloy coils have become an important part of the production process of the plate and strip plant. After stretching and straightening, the surface of the aluminum plate needs to be cleaned with an alkaline cleaning solution with a pH value greater than 10 to remove dirt and residues on the surface of the aluminum plate.

[0003] In order to check the cleaning quality, the machine needs to be temporarily stopped during the cleaning process to check whether the aluminum plate is cleaned. However, due to the fixed nozzle inside the existing cleaning device, there is still residual pressure in the nozzle when the machine is stopped. The cleaning liquid is directly sprayed on a certain area of ​​the aluminum plate, which can easily cause point-like alkaline corrosion on the surface of the aluminum plate, and thus cannot meet the production quality of the aluminum plate.

[0004] In summary, how to propose a cleaning device to address the above technical issues has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0007] The liquid storage box is provided with a plurality of groups of mounting holes and long strip holes for aluminum plates to pass through, and a supporting plate is fixedly connected to the liquid storage box.

[0008] The spraying unit is arranged on two surfaces of the aluminum plate, and comprises a rotatable spraying pipe, a swing cylinder, two bearing seats and two spraying pipe transparent covers.

[0009] The rotatable spray pipe is coaxially arranged with the mounting hole, one end of the rotatable spray pipe is closed, and a quick connector is installed at the other end of the rotatable spray pipe. A V-shaped drainage groove and a plurality of connecting sleeves are fixedly connected to the rotatable spray pipe, and the V-shaped drainage groove and the connecting sleeves are arranged at 180° on the circumferential surface of the rotatable spray pipe. The length direction of the V-shaped drainage groove is parallel to the axial direction of the rotatable spray pipe, the axes of the plurality of connecting sleeves are perpendicular to the axis of the rotatable spray pipe, and the plurality of connecting sleeves are arranged at equal intervals along the axial direction of the rotatable spray pipe, and each connecting sleeve is installed with a fan-shaped nozzle.

[0010] The bearing seat and the spray pipe cover are both sleeved on the rotatable spray pipe, the seat body of the bearing seat is fixedly connected with the support plate, and the spray pipe cover is connected with the liquid storage tank through screws.

[0011] The swing cylinder is fixedly connected to the closed end of the rotatable injection pipe, and the cylinder body of the swing cylinder is fixedly connected to the support plate.

[0012] Furthermore, the diameter of the mounting hole on the liquid storage tank is larger than the sum of the diameter of the rotatable spray pipe and the length of the connecting sleeve.

[0013] Compared with the prior art, the utility model has the following effects:

[0014] 1. The utility model has a simple structure and is easy to operate. During the cleaning process of the aluminum plate, the fan-shaped nozzles on the upper and lower surfaces of the aluminum plate spray cleaning liquid to clean the aluminum plate.

[0039] How it works

[0040] Combination Figures 1 to 5 Explain the working principle of the utility model:

[0041] The aluminum plate passes through one side elevation of the liquid storage tank 6 and comes out from the other side elevation. The aluminum plate is parallel to the horizontal plane, and the injection units are arranged on both surfaces of the aluminum plate. The rotatable injection pipe 1 is coaxially arranged with the mounting hole to enable the rotatable injection pipe 1 to pass through the liquid storage tank 6.

[0042] The swing cylinder 2 can drive the rotatable spray pipe 1 to rotate. The rotatable spray pipe 1 is equipped with a quick connector 1-3. When the rotatable spray pipe 1 rotates, the cleaning liquid supply pipeline connected to the quick connector 1-3 does not rotate, and the fan-shaped nozzle sprays cleaning liquid to clean the two surfaces of the aluminum plate.

[0043] During the cleaning process of the aluminum plate, the angles between the axes of the fan-shaped nozzles on the upper and lower surfaces of the aluminum plate and the aluminum plate are both 45°; when the machine is stopped for inspection, the swing cylinder 2 drives the rotatable spray pipe 1 to rotate, and the angles between the axes of the fan-shaped nozzles on the upper and lower surfaces of the aluminum plate and the aluminum plate are both 90°, and the spray holes of the fan-shaped nozzles are away from the upper and lower surfaces of the aluminum plate.

[0044] The cleaning liquid that continues to be sprayed outward by the fan-shaped nozzle on the upper surface of the aluminum plate due to the residual pressure is received by the V-shaped drainage groove 1-1, and then the cleaning liquid is guided into the liquid storage tank 6 along the V-shaped drainage groove 1-1; the cleaning liquid that continues to be sprayed outward by the fan-shaped nozzle on the lower surface of the aluminum plate due to the residual pressure is directly sprayed onto the bottom plate of the liquid storage tank 6, thereby preventing the cleaning liquid from causing alkaline corrosion to the upper and lower surfaces of the aluminum plate.

[0045] The present invention has been disclosed as above in the form of a preferred embodiment, but it is not intended to limit the present invention. Any simple modification, equivalent changes and modifications made to the above implementation cases by any professional and technical personnel who do not deviate from the content of the technical solution of the present invention and based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
