[0030] Please refer to Figure 1 A circulating anti-sedimentation device for an electrophoretic tank comprises an electrophoretic tank 1, which is used to hold electrophoretic paint. A drain valve 8 connected to the inside of the electrophoretic tank 1 is fixedly connected to one side of the bottom of the electrophoretic tank 1, and the drain valve 8 is used to facilitate the discharge of the electrophoretic paint inside the electrophoretic tank 1 when it is opened. Rollers 4 are rotatably connected to the four corners of the bottom of the electrophoretic tank 1, and the setting of the rollers 4 facilitates the movement of the entire device. A U-shaped push rod 3 is fixedly connected to the side of the auxiliary pool 2 away from the electrophoretic tank 1, and convex particles are evenly arranged on the outer side of the U-shaped push rod 3. The setting of the U-shaped push rod 3 facilitates the pushing of the entire device.

[0031] Please refer to Figure 1 The outer wall of the electrophoretic tank 1 is symmetrically fixedly connected with extension plates 5, and the interiors of the two groups of extension plates 5 are both threadedly connected with adjusting screws 6. The bottom of each group of adjusting screws 6 is fixedly connected with a stop plate 7. The adjusting screws 6 are arranged to drive the stop plate 7 to move up and down when rotating, and the movement of the entire device can be restricted when the stop plate 7 moves downward to contact the ground. A connected auxiliary pool 2 is fixedly connected to one side of the electrophoretic tank 1, and the auxiliary pool 2 is arranged to allow the electrophoretic paint inside the electrophoretic tank 1 to flow into. A circulation pump 16 is fixedly connected to one side wall of the auxiliary pool 2, and a liquid extraction pipe 18 is fixedly connected to the input end of the circulation pump 16. The end of the liquid extraction pipe 18 away from the circulation pump 16 is connected to the auxiliary pool 2, and the circulation pump 16 is arranged to extract the electrophoretic paint inside the auxiliary pool 2 through the liquid extraction pipe 18 when starting the work.

[0032] Please refer to Figure 1-3 A hose 17 is fixedly connected to the output end of the circulation pump 16, and two groups of U-shaped conduits 9 are symmetrically arranged inside the electrophoretic tank 1. A plurality of liquid spraying pipes 10 are evenly and fixedly connected between the two groups of U-shaped conduits 9. Specifically, the liquid spraying ports of each group of liquid spraying pipes 10 are arranged clockwise, so that the electrophoretic paint extracted by the liquid extraction pipe 18 can be guided to the inside of the U-shaped conduit 9 through the hose 17 and finally sprayed out through each group of liquid spraying pipes 10, so that the electrophoretic paint circulates inside the electrophoretic tank 1, thereby reducing the probability of the electrophoretic paint being precipitated inside the electrophoretic tank 1.

[0033] Please refer to Figure 1-3 The end of the hose 17 away from the circulation pump 16 is fixedly connected to the U-shaped conduit 9 on one side. The tops of the two groups of U-shaped conduits 9 are symmetrically fixedly connected with the suspension rods 11. The tops of the two groups of suspension rods 11 on the same side are fixedly connected with the connecting plates 12. The outer wall of the electrophoresis tank 1 is symmetrically fixedly connected with the fixing blocks 14. The bottoms of each group of fixing blocks 14 are symmetrically fixedly connected with the right-angle plates 15. Each group of right-angle plates 15 is fixedly connected to the outer wall of the electrophoresis tank 1. The right-angle plates 15 are used to further connect and fix the electrophoresis tank 1 and the fixing blocks 14, thereby improving the connection stability between the electrophoresis tank 1 and the fixing blocks 14. The tops of each group of fixing blocks 14 are fixedly connected with the first oil cylinder 13, and the fixing blocks 14 are used to provide support for the first oil cylinder 13.

[0034] Please refer to Figure 1-3 The output ends of the first oil cylinders 13 on both sides are fixedly connected to the connecting plates 12 on both sides respectively. The first oil cylinder 13 is used to drive the connecting plates 12, the suspension rods 11 and the U-shaped guide tube 9 to move up and down when starting the work, so as to adjust the height of the liquid spraying pipe 10, so that the liquid spraying pipe 10 can be used at different heights to improve the flexibility of use. Two groups of U-shaped connecting rods 19 are symmetrically arranged above the electrophoresis tank 1. The bottoms of the two groups of U-shaped connecting rods 19 are evenly fixedly connected with a plurality of J-shaped isolation rods 20. The ends of each group of J-shaped isolation rods 20 away from the U-shaped connecting rods 19 are slidably connected to the inner wall of the electrophoresis tank 1. The groups of J-shaped isolation rods 20 on the same side can form a group of partition baskets, so as to isolate the workpiece to be painted, so as to reduce the probability that the liquid spraying pipe 10 touches the workpiece when moving up and down, thereby causing damage to the electrophoretic paint that is not stably attached to the surface of the workpiece.

[0035] Please refer to Figure 1-3 , both sides of the two groups of U-shaped connecting rods 19 are provided with adjustment mechanisms, the adjustment mechanisms include fixed plates 23 fixedly connected to both sides of the U-shaped connecting rods 19, the bottom of each group of fixed plates 23 is provided with a second oil cylinder 21, the output end of each group of second oil cylinders 21 is fixedly connected to each group of fixed plates 23, and the setting of the fixed plate 23 is used to connect the U-shaped connecting rod 19 with the second oil cylinder 21. The bottom of each group of second oil cylinders 21 is fixedly connected with a support block 22, and each group of support blocks 22 is fixedly connected to the outer wall of the electrophoresis tank 1. The setting of the second oil cylinder 21 is used to drive the fixed plate 23, the U-shaped connecting rod 19 and the J-shaped isolation rod 20 to move up and down when starting work, so as to adjust the height of the J-shaped isolation rod 20. The bottoms of the two sets of fixed plates 23 on the same side are fixedly connected with height indicator rods 24, and the bottom height of the height indicator rods 24 is the same as the bottom height of the J-shaped isolation rod 20. The height indicator rods 24 are configured to move up and down synchronously with the U-shaped connecting rod 19 and the fixed plates 23, so that the height of the J-shaped isolation rod 20 can be marked.

[0036] The implementation principle of this application is:

[0037] When in use, each group of second oil cylinders 21 is started according to the height of the workpiece to be painted, so that the second oil cylinder 21 can drive the fixing plate 23, the U-shaped connecting rod 19 and the J-shaped isolation rod 20 to move up and down when starting the work, thereby realizing the height of the J-shaped isolation rod 20 until the distance between the bottom of the J-shaped isolation rod 20 and the liquid level of the electrophoretic paint inside the electrophoretic tank 1 is greater than the height of the workpiece to be painted, and then the workpiece to be painted is placed in the isolation basket formed by the groups of J-shaped isolation rods 20 on the same side, and is hung in the electrophoretic tank 1 with a conductive hanging rod, and then the workpiece is immersed in the electrophoretic paint, and then the workpiece can be electrophoretically painted. During the painting process, the circulating pump 16 can be started so that the circulating pump 16 can pump the liquid level inside the auxiliary tank 2 when starting the work. The electrophoretic paint is extracted into the interior of the hose 17 through the extraction pipe 18, then guided by the U-shaped conduit 9, and finally sprayed out from each group of spray pipes 10, so that the electrophoretic paint inside the electrophoretic tank 1 and the auxiliary tank 2 can circulate, thereby reducing the probability of electrophoretic paint precipitation. When it is necessary to adjust the height of the spray pipe 10, the first oil cylinder 13 can be started, so that the first oil cylinder 13 can drive the connecting plate 12, the U-shaped conduit 9 and each group of spray pipes 10 to move up and down when starting, thereby realizing the adjustment of the height of the spray pipe 10. During the adjustment process, due to the isolation of the workpiece by the J-shaped isolation rod 20, the probability of the workpiece touching the spray pipe 10 or the U-shaped conduit 9 is effectively reduced, thereby reducing the probability of damage to the paint surface on the workpiece surface.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
