Height, the inner wall 102 of the liquid storage tank 10 is higher than the lowest height of the storage basket 6 and moves up and down under the drum base 5, and the bottom plate 19 of the liquid storage tank 10 is connected to the power end of the lifting power device, wherein the bottom plate 19 and the power end of the lifting power device can be directly connected, or directly supported by the power end, so when the power end rises, it will push the liquid storage tank 10 to rise, and when the power end falls, the liquid storage tank 10 will fall by its own weight; the outer and inner walls 102 of the liquid storage tank 10 and the bottom plate 19 together form a liquid storage cavity for convenient storage of the dipping liquid; the inner wall 102 of the liquid storage tank 10 forms a central sleeve hole for being mounted on the outside of the mounting sleeve 3; the mounting sleeve 3 is provided with a splash-proof structure on the outside, and the liquid storage tank 10 is provided with an outer shell 11, which is fixedly mounted on the mounting base 1, and the outer shell 11 is provided with an openable and closable cover 12.

[0031] In the present embodiment, an opening 13 is provided above the storage basket 6, and an inner eaves extending toward the center is provided at the edge of the opening 13. The drum base 5 is a circular structure, and the sleeve portion 7 of the storage basket 6 is a circular groove matched with the drum base 5. The edge of the drum base 5 is also provided with an inclined chamfer 14 guided by the circular groove, and the accommodating portion 8 of the storage basket 6 is annular; an inner eaves is provided at the edge of the opening 13 of the storage basket 6, which can effectively narrow the range of the opening 13 and prevent the dipping liquid from being thrown out from the opening 13 during centrifugation, thereby reducing the sputtering range.

The inner annular baffle 18 is fixed around the mounting base 1 and is located between the inside of the liquid storage tank 10 and the mounting sleeve 3. Since the storage basket 6 rotates during dipping and the storage basket 6 rotates rapidly during centrifugation, the inner annular baffle 18 can prevent the dipping liquid from splashing into the mounting sleeve 3. The outer annular baffle 17 can effectively slow down the dripping of the dipping liquid in the accommodating portion 8 and prevent splashing caused by dripping after the liquid storage tank 10 descends, thereby further improving the splash-proof effect.

[0034] Furthermore, the lower end of the outer annular baffle 17 is provided with an outer edge extending outward, further reducing the distance between the outer annular baffle 17 and the storage basket 6 receiving portion 8, so that the coating liquid dripping from the receiving portion 8 can be effectively blocked by the outer edge, further slowing down the dripping speed and reducing the sputtering effect.

[0035] In this embodiment, rotating bearings 21 are provided at both ends of the mounting sleeve 3, and the driving spindle 4 is rotatably installed in the mounting sleeve 3 through the rotating bearings 21. Limiting end plates 20 for limiting the rotating bearings 21 are fixedly installed at both ends of the mounting sleeve 3; a spindle sealing ring 22 is also provided between the limiting end plate 20 and the driving spindle 4; this can ensure that the driving spindle 4 can rotate stably in the mounting sleeve 3, and the spindle sealing ring 22 can improve the sealing between the driving spindle 4 and the mounting sleeve 3, thereby improving the sealing effect.

When dipping, the centrifugal motor 23 controls the driving spindle 4 to rotate slowly and uniformly, which can ensure that the workpiece can be coated. Then, when centrifuging, it is only necessary to control the driving spindle 4 to rotate quickly, which effectively improves the use effect.

[0037] The cover plate 12 and the shell 11 are hingedly connected, and the cover plate 12 is also provided with a viewing mirror 26 for observing the interior of the shell 11; it is convenient to open the cover plate 12, place the storage basket 6 and perform maintenance and inspection on the interior, and the cover plate 12 and the shell 11 can be effectively fixed by a lock or other switch structure. When the cover plate 12 is closed, the viewing mirror 26 can be used to conveniently observe whether the internal operation is accurate, thereby improving convenience; the viewing mirror 26 is an existing structure available on the market, and therefore it is not described in detail in this article.

[0038] The working principle of this embodiment is as follows: first, the cover plate 12 is opened, and the workpiece is placed in the accommodating portion 8. The liquid storage tank 10 contains the dipping liquid. Then, the lifting cylinder 15 rises to drive the liquid storage tank 10 to rise, and the dipping liquid covers the workpiece in the accommodating portion 8. Then, the centrifugal motor 23 drives the driving spindle 4 to rotate slowly and uniformly, so that the accommodating portion 8 of the storage basket 6 rotates in the liquid storage tank 10. After the dipping is completed, the driving spindle 4 stops rotating, and the liquid storage tank 10 descends. Then, the centrifugal motor 23 drives the driving spindle 4 to rotate rapidly centrifugally, and the excess dipping liquid in the accommodating portion 8 is thrown out from the hollow hole 9 to complete the drying.
