Description

Technical Field

[0001] This utility model relates to the field of electrophoretic coating technology, specifically to an electrophoretic tank for electrophoretic coating. Background Technology

[0002] An electrophoretic coating tank is a device used for electrophoretic coating. It is a coating method that uses an external electric field to cause pigments and resin particles suspended in an electrophoretic solution to migrate directionally and deposit on the surface of a substrate, which is one of the electrodes. The principle of electrophoretic coating was invented in the late 1930s, but the development of this technology and its industrial application only began after 1963. Electrophoretic coating is a special film formation method that has been developed in the last 30 years. It is the most practical construction process for water-based coatings. It has the characteristics of water solubility, non-toxicity, and easy automation control, and has been rapidly and widely used in the automotive, building materials, hardware, and home appliance industries.

[0003] Compared with existing technologies: During the electrophoretic coating process, paint particles in the electrophoretic tank are prone to sedimentation. If there is no anti-sedimentation mechanism, the sedimented particles will cause uneven coating thickness, rough surface, and even defects such as pinholes and orange peel on the workpiece surface. These defects not only affect the appearance quality of the product, but may also reduce the product's corrosion resistance.

[0004] Therefore, an electrophoresis tank for electrophoretic coating is proposed. Utility Model Content

Example

[0026] Based on the existing problem that deposited particles can cause uneven coating thickness, rough surface, and even defects such as pinholes and orange peel on the workpiece surface, please refer to [the relevant documentation]. Figures 1-3 The present invention provides a technical solution: an electrophoresis tank for electrophoretic coating, comprising an electrophoresis tank body 1, an anti-settling mechanism 2 and an electrophoretic coating mechanism 3 provided on the inner side of the electrophoresis tank body 1;

[0027] The anti-sedimentation mechanism 2 includes a circulation section 21 and a rotating section 22;

[0028] The rotating part 22 is located on the inner side of the circulating part 21;

[0029] The electrophoretic coating mechanism 3 includes a lifting part 31 and an electrophoretic coating part 32;

[0030] The electrophoretic coating section 32 is located on the bottom surface of the lifting section 31.

[0031] The circulation section 21 includes a drain pipe 211, which is connected to the electrophoresis tank body 1. A fixing plate 212 is provided on the rear side of the drain pipe 211, and the fixing plate 212 is fixedly connected to the rear side of the electrophoresis tank body 1. A circulation pump 213 is provided on the top surface of the fixing plate 212, and the circulation pump 213 is fixedly connected to the fixing plate 212.

[0032] A connecting pipe 214 is provided on the left end face of the circulating pump 213. The connecting pipe 214 extends through to the inner side of the electrophoresis tank body 1. A branch pipe 215 is provided on the right side of the connecting pipe 214, and the branch pipe 215 is connected to the circulating pump 213.

[0033] The rotating part 22 includes a U-shaped tube 221, which is connected to the branch pipe 215. The U-shaped tube 221 extends through to the inner side of the electrophoresis tank body 1. The inner end face of the U-shaped tube 221 is connected to a nozzle 222. A U-shaped plate 223 is provided below each nozzle 222. The top surface of the U-shaped plate 223 is fixedly connected to the bottom surface of the electrophoresis tank body 1.

[0034] Motor 224 is provided on the inner side of U-shaped plate 223. Motor 224 is fixedly connected to U-shaped plate 223. Rotating rod 225 is provided on the output end face of motor 224. Rotating rod 225 is fixedly connected to motor 224. Rotating rod 225 extends through to the inner side of electrophoresis tank body 1. Rotating rod 225 is rotatably connected to the inner wall of electrophoresis tank body 1 through bearing seat. Rotating blade 226 is sleeved on the surface of rotating rod 225. Rotating blade 226 is fixedly connected to rotating rod 225.

[0035] Furthermore, in this embodiment, the anti-sedimentation mechanism 2 utilizes the circulation pump 213 in the circulation section 21 to drive the circulation pump 213 to operate. The circulation pump 213 draws the tank liquid containing suspended coating particles from the bottom of the electrophoresis tank body 1 through the connecting pipe 214. After the tank liquid is pressurized by the circulation pump 213, it enters the U-shaped pipe 221 through the branch pipe 215 and finally sprays out at high speed from the nozzle 222 at the end of the U-shaped pipe 221, forming a vertically upward directional jet. At the same time as the circulation pump 213 is operating, the motor 224 is started. The motor 224 drives the rotating rod 225 to rotate, which drives the rotating blade 226 to stir in the tank liquid. The position of the rotating blade 226 is complementary to the jet range of the nozzle 222, covering the tank edge and dead corners that the circulation pump 213 cannot reach. The jet of the circulation pump 213 lifts the bottom particles to the middle layer of the tank. The rotating blade 226 makes the particles evenly distributed through shearing and diffusion.

[0036] Furthermore, in this embodiment, the anti-settling mechanism 2 utilizes the circulation pump 213 in the circulation section 21. The circulation pump 213 is started, and the circulation pump 213 extracts the electrophoresis tank body 1 through the connecting pipe 214. The extracted material enters the branch pipe 215 through the circulation pump 213, reaches the U-shaped pipe 221, and is finally sprayed out from the nozzle 222. At the same time, the motor 224 is started, and the motor 224 drives the rotating rod 225, causing the rotating rod 225 to rotate with the rotating blade 226. This avoids the deposition of coating particles in the electrophoresis tank body 1, which would cause uneven coating thickness, rough surface, or even defects such as pinholes and orange peel on the workpiece surface. Example

[0037] Please see Figure 1 , Figure 2 , Figure 4 Furthermore, based on Embodiment 1, the following is obtained: the lifting part 31 includes a gate-shaped plate 311, which is fixedly connected to the electrophoresis tank body 1. The inner side of the gate-shaped plate 311 is provided with through slots. A cylinder 312 is provided through the inner wall of the gate-shaped plate 311. A lifting plate 313 is provided on the output end face of the cylinder 312. The lifting plate 313 is fixedly connected to the cylinder 312. An installation slot is provided on the bottom surface of the lifting plate 313.

[0038] The electrophoretic coating unit 32 includes a slider 321, which is fixedly connected to a lifting plate 313. A sliding rod 322 is provided through the inner wall of the slider 321. The sliding rod 322 is slidably connected to the slider 321. The sliding rod 322 is fixedly connected to the inner side of the through groove. A second motor 323 is provided inside the sliding rod 322. The second motor 323 is located inside the mounting groove and is fixedly connected to the mounting groove. A second rotating rod 324 is provided on the output end face of the second motor 323. The second rotating rod 324 is fixedly connected to the second motor 323. A hook 325 is fixedly provided on the surface of the second rotating rod 324.

[0039] Furthermore, in this embodiment, the electrophoretic coating mechanism 3 utilizes the hook 325 in the electrophoretic coating section 32 to suspend the workpiece. The cylinder 312 is activated, and the cylinder 312 drives the lifting plate 313 and the electrophoretic coating section 32 to descend along the slide bar 322 under the action of the slider 321, so that the workpiece descends to 5-10cm directly above the rotating blade 226. The second motor 323 is activated, and the second motor 323 drives the second rotating rod 324 to rotate the hook 325 and the workpiece.

[0040] Furthermore, in this embodiment, the workpiece is hung on the hook 325 in the electrophoretic coating section 32 by the electrophoretic coating mechanism 3. The cylinder 312 is started, and the cylinder 312 drives the lifting plate 313 and the electrophoretic coating section 32 to slide on the surface of the slide rod 322 under the action of the slider 321, thereby descending. When it descends above the rotating blade 226, the motor 323 is started. The motor 323 drives the rotating rod 324, which in turn drives the hook 325 and the workpiece to rotate, thereby making the electrophoretic coating uniform and improving work efficiency.

[0041] In use, coating is injected into the electrophoresis tank body 1. Through the anti-sedimentation mechanism 2, the circulation pump 213 in the circulation section 21 is driven to operate. The circulation pump 213 draws the tank solution containing suspended coating particles from the bottom of the electrophoresis tank body 1 through the connecting pipe 214. After being pressurized by the circulation pump 213, the tank solution enters the U-shaped tube 221 through the branch pipe 215, and finally is ejected at high speed from the nozzle 222 at the end of the U-shaped tube 221, forming a vertically upward directional jet. Simultaneously with the operation of the circulation pump 213, the motor 224 is started. The motor 224 drives the rotating rod 225 to rotate, causing the rotating blades 226 to agitate the tank solution. The position of the rotating blades 226 is within the jet range of the nozzle 222. The system complements and covers the tank edges and dead corners that the circulating pump 213 cannot reach. The jet from the circulating pump 213 lifts the bottom particles to the middle layer of the tank. The rotating blades 226 distribute the particles evenly through shearing and diffusion. The workpiece is then suspended by the hooks 325 in the electrophoretic coating section 32 through the electrophoretic coating mechanism 3. The cylinder 312 is started, and the cylinder 312 drives the lifting plate 313 and the electrophoretic coating section 32 to descend along the slide bar 322 under the action of the slider 321. The workpiece is lowered to 5-10cm directly above the rotating blades 226. The second motor 323 is started, and the second motor 323 drives the second rotating rod 324 to rotate the hooks 325 and the workpiece, thereby performing electrophoretic coating.
