[0002] Electrophoretic coating is a coating process, also known as electrophoretic painting or electrophoretic coating. It is a method of applying the paint evenly on the surface of the workpiece using the principle of electrophoresis.

[0003] The electrophoretic coating step includes immersing the workpiece in an electrophoretic tank containing paint particles, and the paint particles are uniformly deposited on the surface of the workpiece to form a coating through the action of an electric field. The electrophoretic tank in the prior art currently establishes an electric plant in the electrophoretic tank, so that the paint can move to the surface of the workpiece through the action of the electric plant. However, before the workpiece enters the electrophoretic tank, the paint particles are easily precipitated in the electric tank and cannot be evenly suspended, so that the particles are easily deposited, resulting in uneven coating. In this regard, an electrophoretic tank for electrophoretic coating is proposed to solve the above-mentioned problems. Summary of the invention

[0004] In order to solve the deficiencies in the prior art, the utility model provides an electrophoretic tank for electrophoretic coating, which has the advantages of an additional stirring system to ensure that the paint particles are evenly suspended in the electrophoretic tank.

[0008] A further improvement to the above technical solution is that a connecting sleeve is fixedly installed on one end of the connecting plate, the connecting sleeve is sleeved on the power end of the motor, and the stirring element is connected to the other end of the connecting plate.

[0009] A further improvement to the above technical solution is that: a pin is fixedly mounted on the top of the electrode frame, and sealing strips are embedded on both the front and rear side surfaces of the electrode frame, and the sealing strips are tightly fitted to the baffle.

[0010] A further improvement to the above technical solution is that the stirring member includes a stirring shaft and a blade structure fixed to the end of the stirring shaft, the stirring shaft is rotatably connected to a connecting plate, and one end of the connecting plate connected to the stirring shaft is bent toward a side away from the baffle.

[0011] A further improvement to the above technical solution is that the blade structure includes two frame-shaped installation frames and blades attached to the inner walls of the installation frames, wherein the two installation frames are welded in a cross shape, and connecting blocks are integrally protruded on the cross-staggered ends of the installation frames, and the connecting blocks are fixedly connected to the stirring shaft.

[0012] A further improvement to the above technical solution is that a mounting plate is fixedly mounted on the inner wall of the baffle, the mounting plate is penetrated by the power end of the motor, a truncated cone-shaped fan-shaped toothed plate is fixedly mounted on the outer ring of the mounting plate, and the stirring element also includes a gear shaft fixedly connected to the end of the stirring shaft, and the gear shaft teeth are meshed with the fan-shaped toothed plate.

[0013] Beneficial effect: Compared with the prior art, the technical solution of the utility model forms an electrophoretic tank by arranging an electrophoretic tank surrounded by a relatively movable baffle on the electrode frame, and the stirring device is arranged on the baffle. On the one hand, it is convenient to maintain the stirring device by directly removing the baffle, and on the other hand, different stirring devices can be flexibly replaced to adapt to the electrode frame.

[0022] This design enables the middle part of the electrode frame 1 to form an electrophoresis tank between the two baffles 5. On the one hand, it is convenient to directly remove the baffle 5 to maintain the stirring device. On the other hand, different stirring devices can be flexibly replaced to adapt to the electrode frame 1, thereby improving the convenience of use.

[0023] In this embodiment, the stirring device includes a motor 6 as a driving element, a connecting plate 10 connected to the power end of the motor 6, and a stirring member installed on the connecting plate 10;

[0024] In a specific implementation, the motor 6 controls the connecting plate 10 to drive the stirring element to rotate to stir the coating in the electrophoresis tank so that the coating is evenly suspended and distributed;

[0025] It should be noted that a connecting sleeve 9 is fixedly mounted on one end of the connecting plate 10, the connecting sleeve 9 is sleeved on the power end of the motor 6, and the stirring element is connected to the other end of the connecting plate 10;

[0026] Such a design enables the connecting plate 10 to rotate with the connecting sleeve 9 as the rotation center, and at the same time enables the stirring element to swing along with the rotation of the connecting plate 10 .

[0027] In this embodiment, a pin 2 is fixedly installed on the top of the electrode frame 1, and sealing strips 3 are embedded on the front and rear side surfaces of the electrode frame 1. The sealing strips 3 fit tightly to the baffle 5. The sealing strips 3 can effectively improve the sealing effect of the electrophoresis tank under the baffle 5.

[0028] The stirring member in this embodiment includes a stirring shaft 11 and a blade structure fixed to the end of the stirring shaft 11. The stirring shaft 11 is rotatably connected to the connecting plate 10, and one end of the connecting plate 10 connected to the stirring shaft 11 is bent toward a side away from the baffle 5.

[0029] By bending the connection of the stirring shaft 11 , the stirring shaft 11 is allowed to deviate at a larger angle from the power axis of the motor 6 , thereby obtaining a larger rotation range.

[0030] In this embodiment, the blade structure includes two frame-shaped installation frames 13 and blades 14 attached to the inner wall of the installation frames 13, wherein the two installation frames 13 are welded in a cross shape.

[0031] It should be noted that a connecting block 15 is integrally protruded on the cross-staggered end of the mounting frame 13, and the connecting block 15 is fixedly connected to the stirring shaft 11.

[0032] In a specific embodiment, the stirring shaft 11 rotates, so that the mounting frame 13 connected to the stirring shaft 11 rotates, thereby stirring the coating material through the blades 14 .

[0033] In order to expand the stirring effect, a mounting plate 7 is fixedly mounted on the inner wall of the baffle 5 in this embodiment, and the mounting plate 7 is penetrated by the power end of the motor 6;

[0037] The working principle of this utility model:

[0038] By selecting an electrode frame 1 and a baffle 5 of suitable width, the baffle 5 is inserted into the electrode frame 1 from the front and rear sides of the electrode frame 1, and the baffle 5 is restricted by the fixing frame 4 outside the electrode frame 1 to fit tightly to the sealing strip 3, so that an electrophoresis tank is enclosed between the electrode frame 1 and the baffle 5. At this time, current is connected to the two pins 2 on the electrode frame 1, so that the electrophoresis phenomenon can be formed. By controlling the motor 6 located on the baffle 5, the motor 6 drives the connecting plate 10 on the power end to rotate with the connecting shaft sleeve 9 as the rotation center, and at the same time, the stirring shaft 11 It can swing with the rotation of the connecting plate 10. At this time, the mounting frame 13 and the blades 14 connected to the end of the stirring shaft 11 rotate around the shaft core of the motor 6. At the same time, the connecting plate 10 can drive the stirring shaft 11 to rotate around the mounting disk 7 during rotation, so it can pull the gear shaft 12 to rotate during one circle of rotation. The gear shaft 12 further rotates the stirring shaft 11 relative to the connecting plate 10 during rotation. The stirring shaft 11 drives the mounting frame 13 connected to the stirring shaft 11 to rotate during its own rotation, thereby stirring the paint through the blades 14.
