The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0032] In one embodiment of this utility model, such as Figure 1-5As shown, a single-cylinder centrifugal electroplating machine's lower plating tank includes a mounting frame 1, a conductive component 2, a rotating component 3, an electroplating tank body 4, a drive device 5, and a bearing seat 6. The rotating component 3 is rotatably mounted on the bearing seat 6, with one end connected to the electroplating tank body 4 and the other end connected to the conductive component 2. The drive device 5 drives the rotating component 3 to rotate. The conductive component 2 is mounted on the mounting frame 1 and is electrically connected to the electroplating tank body 4 via the rotating component 3. The rotating component 3 includes an inner tube 31, a flow-stop ball 32, and a drain nozzle 33.One end of the inner tube 31 is connected to the electroplating tank 4, and the other end of the inner tube 31 is connected to one end of the drain nozzle 33. The other end of the drain nozzle 33 is provided with a drain outlet 331. The stop ball 32 is movably installed inside the drain nozzle 33 and can block the drain outlet 331. In this embodiment, the bearing seat 6 and the mounting bracket 1 are specifically installed on the body of the single-cylinder centrifugal electroplating machine. The mounting bracket 1 is located below the bearing seat 6. A push rod is provided below the rotating assembly 3. The push rod is used to lift the stop ball 32. It should be noted that the diameter of the stop ball 32 is larger than the diameter of the drain outlet 331, and the diameter of the stop ball 32 is smaller than the diameter of the internal pipe of the drain nozzle 33, so that the stop ball 32 can move up and down inside the drain nozzle 33. During installation, the mounting bracket 1 and the bearing seat 6 are respectively installed... The rotating assembly 3 is mounted inside the bearing seat 6 within the body of the single-cylinder centrifugal electroplating machine. The top of the rotating assembly 3 is mounted to the bottom of the electroplating tank 4, and the top of the inner tube 31 is connected to the interior of the electroplating tank 4, allowing the rotating assembly 3 to drive the electroplating tank 4 to rotate. Then, the conductive assembly 2 is mounted on the mounting bracket 1 and connected to the bottom of the rotating assembly 3, enabling the conductive assembly 2 to be electrically connected to the electroplating tank 4 via the rotating assembly 3. Specifically, the conductive assembly 2 is connected to the electroplating tank 4 via a wire. The negative terminal of the power supply is electrically connected. The drive device 5 is mounted on the mounting bracket 1, and the output end of the drive device 5 is connected to the rotating assembly 3. During operation, the workpiece to be plated and the electroplating solution are added into the electroplating tank 4, and the anode titanium basket extends into the electroplating tank 4 to supply electroplating chemicals. It should be noted that the anode titanium basket is connected to the chemical tank. The power supply provides power to the conductive assembly 2 through a wire. The conductive assembly 2, through the rotating assembly 3, energizes the electroplating tank 4 as a cathode, thereby electroplating the workpiece to be plated. At the same time, the drive device 5 drives the rotating assembly 3. When component 3 rotates, the rotating component 3 drives the electroplating tank 4 to rotate. At this time, the stop ball 32 blocks the drain port 331 of the drain nozzle 33. When it is necessary to discharge the electroplating liquid in the electroplating tank 4, the push rod below the rotating component 3 moves upward. The push rod lifts the stop ball 32, so that the stop ball 32 cannot block the drain port 331. Thus, the electroplating liquid in the electroplating tank 4 is discharged from the drain port 331 through the inner tube 31 and the drain nozzle 33 in sequence. Furthermore, when cleaning the electroplating tank 4, the cleaning water inside it is also discharged through the drain port 331.This application utilizes a mounting frame 1, a conductive component 2, a rotating component 3, an inner tube 31, a stop ball 32, a drain nozzle 33, a drain outlet 331, an electroplating tank body 4, a drive device 5, and a bearing seat 6. During draining, simply lifting the stop ball 32 is sufficient, making operation simple and draining convenient and quick. During the electroplating or cleaning process, the stop ball automatically resets under hydraulic pressure, firmly blocking the drain outlet 331 of the drain nozzle 33, preventing leakage of electroplating solution or cleaning water. This not only ensures the quality and efficiency of electroplating or cleaning but also avoids waste of electroplating solution and cleaning water. Furthermore, it prevents leakage of electroplating solution or cleaning water that could corrode parts or cause rust, thus improving the service life of the lower discharge tank of the single-cylinder centrifugal electroplating machine.

During operation, the driving device 5 drives the transmission rod 34 to rotate, and the transmission rod 34 drives the electroplating tank 4 to rotate through the turntable 35, which is convenient, fast, and has high transmission efficiency. Preferably, the bottom of the inner tube 31 is provided with a flared opening, and the inner tube 31 is connected to the drain nozzle 33 through the flared opening. The diameter of the inner tube 31 is smaller than the diameter of the stop ball 32, thereby preventing the stop ball 32 from entering the inner tube 31.

[0034] like Figure 3-4As shown, the rotating assembly 3 also includes a sealing ring 37, which is installed on the turntable 35 and located at the connection between the inner tube 31 and the electroplating tank 4. In this embodiment, the sealing ring 37 is a silicone ring. The sealing ring 37 is provided at the connection between the electroplating tank 4 and the inner tube 31, and it serves a sealing function to prevent electroplating solution or cleaning water from seeping out from the gaps.

[0035] like Figure 1 and Figure 3 As shown, the driving device 5 includes a first pulley 51, a second pulley 52, a transmission belt 53, and a driving unit 54; the driving unit 54 is mounted on the mounting frame 1, the first pulley 51 is mounted on the output end of the driving unit 54, the second pulley 52 is mounted on the outer periphery of the transmission rod 34, and the second pulley 52 is connected to the first pulley 51 through the transmission belt 53. In this embodiment, the drive unit 54 is a motor, which is mounted on the mounting bracket 1. The output end of the drive unit 54 is equipped with the first pulley 51, and the second pulley 52 is specifically mounted on the outer periphery of the bottom of the transmission rod 34 through an expansion sleeve. The second pulley 52 is located above the drain nozzle 33, and the second pulley 52 is connected to the first pulley 51 through the transmission belt 53. During operation, the drive unit 54 drives the first pulley 51 to rotate, and the first pulley 51 drives the second pulley 52 to rotate through the transmission belt 53, thereby causing the second pulley 52 to drive the transmission rod 34 to rotate, which in turn causes the electroplating tank 4 to rotate. This is convenient, fast, and has high transmission efficiency.

[0036] like Figure 1-3As shown, the conductive component 2 includes a rubber pad 21, a fixing plate 22, an electric clamp fixing nail 23, a conductive clamp 24, a first locking screw 25, a locking nut 26, and a conductive ring 27.

The bottom of the two fixing plates 22 is respectively mounted on the electric clamp fixing pin 23. One end of each of the two conductive clamps 24 is clamped to the electric clamp fixing pin 23 by the first locking screw 25 and the locking nut 26. The other end of 4 is clamped to the outer periphery of the conductive ring 27, which is installed on the outer periphery of the transmission rod 34. The conductive ring 27 is located above the second pulley 52, and the negative terminal of the power supply is wound around the first locking screw 25 through a wire and locked and clamped by the locking nut 26. During operation, the negative terminal of the power supply supplies power to the electroplating tank 4 through the first locking screw 25, the conductive clamp 24, the transmission rod 34 and the turntable 35 in sequence, so that the electroplating tank 4 serves as the cathode of electroplating. This embodiment adopts a double electric clamp wrapping clamping structure, which is beneficial to ensure the stability of current transmission.

[0037] like Figure 1-2 As shown, it also includes a protective cover 7, which is mounted on the mounting frame 1 and covers the conductive clip 24 and the conductive ring 27. In this embodiment, the protective cover 7 protects the conductive clip 24 and the conductive ring 27, preventing them from being disturbed by external factors during the conduction process, which helps to ensure the stability and reliability of electroplating.

[0038] like Figure 1-4As shown, the electroplating tank 4 includes a chassis 41, a plating dish 42, a cathode ring 43, a cathode cover 44, a pressure cap 45, and a second locking screw 46.

The cover 44, the cathode ring 43, and the plating dish 42 are mounted on the turntable 35; the base 41 is mounted on the bottom of the plating dish 42, and the bottom surface of the base 41 is connected to the top surface of the turntable 35. The base 41 is provided with a confluence hole 411. The plating dish 42 is provided with a plurality of mesh holes 421. The plurality of mesh holes 421 are evenly spaced along the circumferential direction of the plating dish 42, and the plurality of mesh holes 421 are connected to the inner tube 31 through the confluence hole 411.

Then, the pressure cap 45, cathode cover 44, cathode ring 43, and plating dish 42 are connected sequentially using the ends of multiple second locking screws 46. The ends of the second locking screws 46 are installed on the turntable 35. Then, the base plate 41 is installed in the middle of the bottom of the plating dish 42. The number of mesh holes 421 is eight. Each mesh hole 421 is equipped with a filter screen to prevent the workpiece to be plated from falling into the mesh holes 421 and causing blockage. During drainage, the electroplating solution or cleaning water is discharged from the eight mesh holes 421 into the area between the base plate 41 and the plating dish 42, then discharged from the manifold 411 into the inner tube 31, and finally discharged from the drain nozzle 33, which is convenient and quick.

[0039] like Figure 5As shown, it also includes a drain pan 8, which is located below the electroplating tank 4. The drain pan 8 is used to drain wastewater from the outer periphery of the electroplating tank 4.

When cleaning the top cover, the wastewater exists on the outer periphery of the electroplating tank 4. In order to discharge the wastewater on the outer periphery of the electroplating tank 4, the drain tray 8 is provided for unified collection and discharge of the wastewater. Specifically, the drain tray 8 is installed on the body of the single-cylinder centrifugal electroplating machine. The drain tray 8 is located below the electroplating tank 4. Its inner baffle 81 is located on the outer periphery of the bearing seat 6, and its outer baffle 82 is located on the outer periphery of the electroplating tank 4, so that the wastewater from cleaning the top cover is located between the inner baffle 81 and the outer baffle 82 and is discharged from the drain hole 83, which is convenient and quick.

[0040] like Figure 5 As shown, it also includes a waterproof ring 9, which is installed on the bottom surface of the turntable 35 and located on the outer periphery of the inner baffle plate 81.
