The upper surface of the bottom plate 5 is fixedly connected with a cover plate 6. The upper surface of the cover plate 6 is fixedly connected with a main cleaning component 2. The bottom of the inner cavity of the box body 1 is fixedly connected with a main motor 3 through a waterproof shell. The output shaft of the main motor 3 is fixedly connected with the lower surface of the bottom plate 5 through a connecting piece. At the same time, the inner side surface of the box body 1 and the upper surface of the limiting ring 7 are both fixedly connected with guide plates 10. The fixed frame 11 is fixedly connected to the upper surface of the box body 1. The top of the fixed frame 11 is fixedly connected with a cylinder 14 through a groove. The multi-stage telescopic rod of the cylinder 14 is fixedly connected with a pressing plate 13. The lower surface of the pressing plate 13 is fixedly connected with a sub-cleaning component 12. At the same time, a guide groove is correspondingly opened at the position of the side surface of the pressing plate 13 relative to the guide plate 10.

[0018] In this embodiment, the precious metal jewelry blank to be cleaned is placed on the surface of the main cleaning component 2. The switch of the cylinder 14 is started, and the multi-stage telescopic rod of the cylinder 14 pushes the pressing plate 13 and the sub-cleaning component 12 to move downward synchronously, so that the sub-cleaning component 12 can abut against the upper surface of the precious metal jewelry blank. The solenoid valve of the liquid injection pipe is opened, and the cleaning liquid flows into the interior of the box body 1 through the liquid injection pipe. After the cleaning liquid submerges the pressing plate 13, the switch of the main motor 3 is started. The output shaft of the main motor 3 drives the fixedly connected bottom plate 5, cover plate 6 and main cleaning component 2 to rotate synchronously through a connecting piece, and then the main cleaning component 2 and the sub-cleaning component 12 can rotate relatively, thereby enhancing the cleaning effect of the rough washing device on the precious metal jewelry blank. Moreover, the cleaning liquid driven by the rotation of the main cleaning component 2 can also perform corresponding auxiliary cleaning on the surface of the precious metal jewelry blank, improving the cleaning effect and cleaning efficiency of the device on the precious metal jewelry blank, and also ensuring the product quality after composite enamel processing. After cleaning, the solenoid valve corresponding to the drain pipe is started to discharge the cleaning liquid in the box body 1 into the recycling device, so that the precious metal jewelry blank is separated from the cleaning liquid. Then the reset switch of the cylinder 14 is started, and the cylinder 14 drives the pressing plate 13 and the sub-cleaning component 12 to reset, and the worker can take out the precious metal jewelry blank.

[0019] As a preferred implementation mode, the box body 1 is integrally in a cylindrical structure, the cross-section of the box body 1 is in a U-shaped structure, and the fixed frame 11 fixedly connected to the upper surface of the box body 1 is in a C-shaped structure.

[0020] In this embodiment, as Figure 1 and Figure 2 , corresponding solenoid valves are respectively arranged on the liquid injection pipe and the liquid discharge pipe, so that the cleaning liquid inside the box body 1 can be conveniently replaced, ensuring the cleaning effect of the device on the noble metal jewelry blank.

[0021] As a preferred embodiment, the limiting ring 7 has an annular structure, and the axial section of the limiting ring 7 has a convex structure. A plurality of limiting plates are fixedly connected at equal intervals along the circumferential direction on the upper surface of the limiting ring 7. At the same time, the limiting plates are all in a strip structure, and the lengths of the two limiting plates close to the fixing frame 11 are greater than the lengths of the limiting plates at other positions, and a buffer layer is fixedly connected to the surface of the limiting plate.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the buffer layer can be made of silica gel material, which can then assist in reducing the impact force of the noble metal jewelry blank colliding with the side of the box body 1, reducing the probability of surface damage to the noble metal jewelry blank. At the same time, the two groups of limiting plates with increased lengths can assist in enhancing the stability of the pressing plate 13 during movement, ensuring that the pressing plate 13 can smoothly embed into the box body 1.

The positioning groove has a square structure, and at the same time, the sizes of the limiting groove and the protruding part of the limiting ring 7 are adapted to each other.

[0024] In this embodiment, as Figure 1 and Figure 4 , the sizes of the limiting groove and the protruding part of the limiting ring 7 are adapted to each other, which can assist in enhancing the stability of the bottom plate 5 during rotation. Moreover, the opening of the positioning groove facilitates the quick positioning and fixing between the cover plate 6 and the bottom plate 5, ensuring that the through holes opened on the cover plate 6 and the bottom plate 5 can be correspondingly communicated.

[0025] As a preferred embodiment, the cover plate 6 has a circular structure. A positioning block 4 is fixedly connected to the position of the cover plate 6 corresponding to the positioning groove on the lower surface. The diameter of the cover plate 6 is equal to the diameter of the lower surface of the bottom plate 5, and the thickness of the combination formed by the cover plate 6 and the bottom plate 5 is equal to the thickness of the outer side surface of the limiting ring 7.

[0026] In this embodiment, as Figure 1 and Figure 4 , the cover plate 6 is fixedly connected to the upper surface of the bottom plate 5, and the combination formed by the cover plate 6 and the bottom plate 5 can be stably movably connected in the box body 1 through the limiting ring 7, ensuring the cleaning effect of the main cleaning component 2 on the noble metal jewelry blank and also reducing the probability of the noble metal jewelry blank sliding towards the edge.

[0027] As a preferred embodiment, the main cleaning assembly 2 is composed of a short brush 8 and a long brush 9. Both the short brush 8 and the long brush 9 are in an annular structure, and the short brush 8 and the long brush 9 are alternately distributed on the surface of the cover plate 6.

And grooves are evenly arranged at equal intervals along the circumferential direction on the upper surface of the long brush 9, so that the cleaning liquid can be driven to rotate synchronously when the long brush 9 rotates, thereby enhancing the cleaning effect on the noble metal jewelry blank. Moreover, the alternating distribution of the long brush 9 and the short brush 8 can enhance the cleaning effect and also can perform corresponding auxiliary limiting on the noble metal jewelry blank to prevent the noble metal jewelry blank from sliding towards the edge.

[0029] As a preferred embodiment, the pressing plate 13 is in a circular structure. Guide grooves are correspondingly opened at the position of the arc surface of the pressing plate 13 relative to the guide plate 10. The guide grooves are in a rectangular structure, and the dimensions of the guide grooves are adapted to those of the guide plate 10. And a plurality of groups of through holes are evenly opened on the surface of the pressing plate 13. The auxiliary cleaning assembly 12 fixedly connected to the lower surface of the pressing plate 13 is in a circular structure. At the same time, the lower surface of the auxiliary cleaning assembly 12 is in a hemispherical structure.

[0030] In this embodiment, as Figure 1 and Figure 2 , the auxiliary cleaning assembly 12 is made of soft brush hair material, which can assist in reducing the probability of damage to the surface of the noble metal jewelry blank. And the groove structure on the lower surface of the auxiliary cleaning assembly 12 can assist in restricting the moving range of the noble metal jewelry blank and reduce the probability of the noble metal jewelry blank shifting towards the edge during the cleaning process. At the same time, the opening of the through holes facilitates the circulation of the cleaning liquid.
