Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, specifically to a galvanized roller structure for metal surface treatment. Background Technology

[0002] Barrel plating refers to the process of plating a large number of small parts in a rotating container. Barrel plating is suitable for plating small parts that cannot or are not suitable for hanging due to factors such as shape and size. Compared with the earlier methods of plating small parts using rack plating or basket plating, it saves labor, improves labor productivity, and greatly improves the surface quality of the plated parts.

[0003] Strictly speaking, barrel plating is called barrel electroplating. It is an electroplating process in which a certain number of small parts are placed in a special barrel and deposited with various metal or alloy coatings on the surface of the parts by means of indirect conductivity while the barrel is rolling, so as to achieve surface protection, decoration and various functional purposes. After the electroplating is completed, the barrel is moved to the outside of the electroplating tank to remove the workpiece. However, after the electroplating is completed, there is still electroplating solution left inside the barrel. During the process of the barrel being moved out, the electroplating solution is continuously dripped out. At the same time, when the workpiece is removed, there is still electroplating solution left on the surface of the workpiece, which is inconvenient to collect and causes waste. To this end, we propose a galvanized barrel structure for metal surface treatment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a galvanized roller structure for metal surface treatment. By changing the position of the roller, it is convenient to drain and collect the workpiece, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a galvanizing roller structure for metal surface treatment, comprising an electroplating tank and a barrel plating mechanism;

[0006] Electroplating tank: Filter plate one and filter plate two are fixedly connected to its front side respectively. The lower end of filter plate one is fixedly connected to the rear end of filter plate two. Filter plate two is an arc-shaped filter plate.

[0007] The barrel plating mechanism includes a connecting plate, a hexagonal cylinder, and a rotating shaft. The upper part of the middle of the electroplating tank is rotatably connected to the rotating shaft. Connecting plates are fixedly sleeved on both the left and right ends of the rotating shaft. A hexagonal cylinder is rotatably connected between the ends of the two connecting plates away from the rotating shaft. A conductive wire is fixedly connected to the upper right side of the electroplating tank. The lower end of the conductive wire passes through the through hole on the right side of the hexagonal cylinder and is placed inside the hexagonal cylinder. The rotation of the roller facilitates the draining and collection of workpieces.

[0008] Furthermore, it also includes a controller, which is located on the left side of the electroplating tank. The input end of the controller is electrically connected to an external power source, and the output end of the conductive wire is electrically connected to the input end of the controller to control electrical appliances.

[0009] Furthermore, a second motor is fixedly connected to the left side of the electroplating tank. The output shaft of the second motor is fixedly connected to the left end of the rotating shaft. The input end of the second motor is electrically connected to the output end of the controller to realize the repositioning of the hexagonal cylinder.

[0010] Furthermore, the barrel plating mechanism also includes a driven gear and a drive assembly. The drive assembly includes a support frame, a drive gear, and a motor. The motor is fixedly connected to both the front and rear ends of the left side of the electroplating tank. The right end of the output shaft of the motor is fixedly fitted with a drive gear. The front and rear ends of the left inner wall of the electroplating tank are fixedly connected to the support frame. The right end of the output shaft of the motor is rotatably connected to the through hole in the middle of the adjacent front and rear support frames. The left end of the hexagonal cylinder is fixedly fitted with a driven gear, which is configured to cooperate with two drive gears. The input end of the motor is electrically connected to the output end of the controller, driving the hexagonal cylinder to rotate.

[0011] Furthermore, the rear sidewall of the electroplating tank is fixedly connected with evenly distributed placement racks for placing the zinc plates of the positive electrode.

[0012] Furthermore, an angle sensor is fixedly connected to the right side of the electroplating tank. The detection shaft of the angle sensor is fixedly connected to the right end of the rotating shaft. The angle sensor is bidirectionally electrically connected to the controller to detect the position of the hexagonal cylinder.

[0013] Furthermore, guide rails are fixedly connected to both the left and right sides of the electroplating tank, and a placement plate is slidably connected between the two guide rails. The placement plate is located on the upper front side of the electroplating tank, and a stop block is fixedly connected to the middle of both the left and right side walls of the electroplating tank. The stop blocks are located at the rear end of the placement plate to facilitate the loading of workpieces.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This galvanized roller structure for metal surface treatment has the following advantages:

[0015] When loading a workpiece, the hexagonal cylinder will not rotate due to the support of the placement plate, making it easy to load the workpiece. The hexagonal cylinder is moved by motor two. When the hexagonal cylinder is at the rear end, it is rotated by motor one on the rear side to achieve zinc plating of the workpiece inside the hexagonal cylinder. When the hexagonal cylinder is at the front end, it is rotated by motor one on the front side to facilitate the return of the electroplating solution to the electroplating tank. After opening the hexagonal cylinder, the workpiece is separated from the electroplating solution again on the upper surface of filter plate one and filter plate two, making it more convenient to remove the workpiece.

[0020] Please see Figure 1-2 This embodiment provides a technical solution: a galvanizing roller structure for metal surface treatment, including an electroplating tank 1 and a barrel plating mechanism 2;

[0021] Electroplating tank 1: Filter plate 4 and filter plate 5 are fixedly connected to its front side. The lower end of filter plate 4 is fixedly connected to the rear end of filter plate 5. Filter plate 5 is an arc-shaped filter plate. The rear wall of electroplating tank 1 is fixedly connected to evenly distributed placement racks 9.

The stop block 12 is located at the rear end of placement plate 7. When placement plate 7 is pushed backward between the two guide rails 6 until it touches the stop block 12, hexagonal cylinder 23 rotates and is placed on the upper end of placement plate 7 to facilitate the placement of workpieces. The electroplating liquid remaining on the surface of the workpiece returns to electroplating tank 1 from the filter holes of filter plate 4 and filter plate 5. Filter plate 5 is an arc-shaped filter plate to prevent workpieces from slipping.

[0022] The barrel plating mechanism 2 includes a connecting plate 22, a hexagonal cylinder 23, and a rotating shaft 24. The rotating shaft 24 is rotatably connected to the upper middle part of the electroplating tank 1. Connecting plates 22 are fixedly fitted onto both ends of the rotating shaft 24. A hexagonal cylinder 23 is rotatably connected between the ends of the two connecting plates 22 furthest from the rotating shaft 24. A conductive wire 3 is fixedly connected to the upper right side of the electroplating tank 1. The lower end of the conductive wire 3 passes through a through hole on the right side of the hexagonal cylinder 23 and is placed inside the hexagonal cylinder 23. A second motor 11 is fixedly connected to the left side of the electroplating tank 1. The output shaft of the second motor 11 is fixedly connected to the left end of the rotating shaft 24. The input end of the second motor 11 is electrically connected to the output end of the controller 8. The barrel plating mechanism 2 also includes a driven... The electroplating tank 1 has gears 21 and drive assembly 25. Drive assembly 25 includes support frame 251, drive gear 252, and motor 253. Motor 253 is fixedly connected to both ends of the left side of the electroplating tank 1. Drive gear 252 is fixedly sleeved on the right end of the output shaft of motor 253. Support frame 251 is fixedly connected to both ends of the left side inner wall of the electroplating tank 1. The right end of the output shaft of motor 253 is rotatably connected to the through hole in the middle of the adjacent support frame 251. Driven gear 21 is fixedly sleeved on the left end of hexagonal cylinder 23. Driven gear 21 is configured to cooperate with two drive gears 252. The input end of motor 253 is electrically connected to control... An angle sensor 10 is fixedly connected to the right side of the electroplating tank 1 at the output end of the device 8. The detection shaft of the angle sensor 10 is fixedly connected to the right end of the rotating shaft 24. The angle sensor 10 is bidirectionally electrically connected to the controller 8. When the output shaft of the second motor 11 rotates, the rotating shaft 24 rotates, the connecting plate 22 rotates, driving the hexagonal cylinder 23 to rotate. The hexagonal cylinder 23 rotates in the opposite direction. The angle sensor 10 detects the rotation angle of the rotating shaft 24 and feeds it back to the controller 8, which facilitates precise control of the position of the hexagonal cylinder 23. The first motor 253 at the rear starts, driving the driving gear 252 at the rear to rotate. The hexagonal cylinder 23 rotates backward. The driven gear 21 contacts the driving gear 252 and meshes with it. Gear 21 is driven to rotate. A zinc plate is placed on the placement rack 9 and the output terminal of the controller 8 is connected. When the hexagonal cylinder 23 rotates, it drives the zinc-plated workpiece inside to rotate in reverse. The lower ends of the conductive wires 3 of some workpieces contact each other and conduct current between the workpieces to form a circuit and realize electroplating. After zinc plating is completed, the hexagonal cylinder 23 rotates in the forward direction. The motor 253 at the front end drives the adjacent driving gear 252 to rotate. The driven gear 21 contacts and meshes with the driving gear 252 at the front end. The hexagonal cylinder 23 rotates, and the electroplating solution flows out from the filter hole of the hexagonal cylinder 23. Then the hexagonal cylinder 23 is opened. As the hexagonal cylinder 23 rotates, the workpiece falls to the upper end of the whole composed of filter plate 4 and filter plate 5.

[0023] It also includes a controller 8, which is located on the left side of the electroplating tank 1. The input end of the controller 8 is electrically connected to an external power source, and the output end of the conductive line 3 is electrically connected to the input end of the controller 8.

[0024] The working principle of the galvanizing roller structure for metal surface treatment provided by this utility model is as follows: The placement plate 7 is pushed backward between the two guide rails 6 until it touches the stop block 12. Then, the output shaft of motor 21 rotates, the rotating shaft 24 rotates, the connecting plate 22 rotates, driving the hexagonal cylinder 23 to rotate. The hexagonal cylinder 23 is placed on top of the placement plate 7. The hexagonal cylinder 23 is opened to fill the workpiece to be galvanized. The hexagonal cylinder 23 is closed, and it rotates in the opposite direction. The angle sensor 10 detects the rotation angle of the rotating shaft 24 and feeds it back to the controller 8 for precise control of the position of the hexagonal cylinder 23. The rear motor 253 starts, driving the rear drive gear 252 to rotate. The hexagonal cylinder 23 rotates backward, and the driven gear 21 contacts and meshes with the drive gear 252, causing the driven gear 21 to rotate. When the zinc plate is placed on the placement rack 9 and the output terminal of the controller 8 is connected, the hexagonal cylinder 23 rotates, causing the zinc-plated workpiece inside to reverse. The lower ends of the conductive wires 3 of some workpieces come into contact and conduct current between the workpieces to form a circuit, thus realizing electroplating. After the zinc plating is completed, the hexagonal cylinder 23 rotates in the forward direction. The motor 253 at the front end drives the adjacent driving gear 252 to rotate. The driven gear 21 contacts and meshes with the driving gear 252 at the front end. The hexagonal cylinder 23 rotates, and the electroplating solution flows out from the filter hole of the hexagonal cylinder 23. Then the hexagonal cylinder 23 is opened. As the hexagonal cylinder 23 rotates, the workpiece falls to the upper end of the whole composed of filter plate 4 and filter plate 5. The electroplating solution remaining on the surface of the workpiece returns to the electroplating tank 1 from the filter hole of filter plate 4 and filter plate 5. Filter plate 25 is an arc-shaped filter plate to prevent the workpiece from slipping.
