Description

Technical Field

[0001] The utility model relates to the technical field of electrophoretic coating, in particular to an electrophoretic tank for matte electrophoretic coating. Background Art

[0002] Matt electrophoretic coating is a surface treatment technology mainly used to improve the corrosion resistance and decorativeness of the workpiece surface. In the coating process, the electrophoretic tank is a key part, which usually includes the tank body, power supply system, electrolyte, stirring system and filtration system. Electrophoretic coating uses the electric field to deposit charged particles from the solution to the electrode surface to form a uniform and dense coating, while matte electrophoretic coating uses the extinction characteristics of the pigment during the deposition process under the action of the electric field. When the pigment particles are deposited on the electrode surface, they cause the surface light to scatter, so that the electrode surface no longer reflects light, but presents an extinction effect.

[0003] In the prior art, an overflow tank is separated inside the electrophoresis tank by a partition, and an overflow port is opened on the partition to filter the coating liquid in the tank to prevent the liquid level in the tank from being too high. However, the height of the overflow port cannot be adjusted for liquid level management according to different workpiece sizes or coating requirements, which affects the coating effect. Utility Model Content

[0004] In view of the problems existing in the background technology, a matte electrophoretic coating electrophoretic tank is proposed. The general scheme and the partition are provided with multiple overflow ports and a blocking component for blocking the overflow ports, which can enable the blocking plate to drive the overflow ports corresponding to the blocking block to be blocked, so that the liquid level of the coating tank is controlled at the required height, which is convenient for the liquid level management under different coating requirements, and further ensures the uniformity of the electrophoretic liquid covering the surface of the workpiece and the consistency of the coating effect.

[0008] The plugging component is arranged on the partition plate and is used for plugging the overflow port and adjusting the overflow height.

[0009] Preferably, the electrophoresis tank body is divided into a coating tank and an overflow tank by a partition.

[0010] Preferably, the filtration assembly includes a filter and a circulation pump. The filter is installed on the base and is located relatively to one side of the electrophoresis tank body.

The circulation pump is installed on the outer wall of the electrophoresis tank body and is connected to the reflux pipe.

[0011] Preferably, three groups of overflow ports are provided, all of which are vertically and equidistantly opened on the partition.

[0023] like Figure 1 As shown, the electrophoresis tank body 2 is divided into a coating tank 5 and an overflow tank 6 by a partition 3 .

[0024] When the liquid level in the coating tank 5 is too high, it will enter the overflow tank 6 through the overflow port 4, so that the height of the electrophoretic liquid level in the coating tank 5 can be controlled.

[0025] like Figure 1 As shown, the filtering assembly includes a filter 7 and a circulation pump 8. The filter 7 is installed on the base 1 and is relatively located on one side of the electrophoresis tank body 2. Its two sides are respectively connected with a liquid extraction pipe 10 connected to the overflow tank 6 and a reflux pipe 9 connected to the coating tank 5. The circulation pump 8 is installed on the outer wall of the electrophoresis tank body 2 and is connected to the reflux pipe 9.

[0026] The liquid entering the overflow tank 6 can be drawn into the filter 7 for filtration through the circulation pump 8 to keep the electrophoretic liquid clean, remove impurities and solid particles to prevent them from affecting the coating quality and the coating of the workpieces in the coating tank 5, and return the filtered electrophoretic liquid to the coating tank 5.

[0027] Embodiment 2

[0028] like Figure 1-Figure 3As shown, the utility model proposes a matte electrophoretic coating electrophoretic tank. On the basis of the above embodiment, this embodiment also records in detail the specific components of the blocking component and the blocking method of the overflow port 4.

[0029] like Figure 3 As shown, the blocking assembly includes a fixed frame 11, a movable plate 12, a transverse axis 13, a spring 14, a blocking plate 15 and a blocking block 16. The fixed frame 11 is arranged on the side opposite to the partition 3, and the movable plate 12 is slidably arranged thereon. The movable plate 12 is symmetrically slidably connected with the transverse axis 13, and a driving member is arranged in the middle of the movable plate 12; one end between the two groups of transverse axes 13 is connected to the blocking plate 15, and the blocking block 16 adapted to the caliber of the overflow port 4 is arranged on the blocking plate 15, and the other end of the transverse axis 13 is connected to the anti-slip plate 17, and the spring 14 is sleeved on the transverse axis 13, and its two ends are respectively abutted against the anti-slip plate 17 and the movable plate 12.

When the overflow port 4 of the corresponding height needs to be blocked, the movable plate 12 is first manually moved so that the movable plate 12 is aligned with the overflow port 4 of the corresponding height along the guide track of the fixed frame 11, and then the hand wheel 20 is turned. The hand wheel 20 drives the threaded rod 18 to rotate and move. During the movement, the end of the threaded rod 18 passes through the movable plate 12 to press the blocking plate 15. The blocking plate 15 drives the horizontal axis 13 to move relative to the movable plate 12 until it abuts against the partition plate 3 and drives the blocking block 16 thereon to block the overflow port 4 of the corresponding height. In the blocking process, the horizontal axis 13 will drive the baffle to squeeze the spring 14. When the pressing force of the threaded rod 18 is lost, the blocking plate 15 will resume movement under the action of the spring 14, thereby opening the overflow port 4.
