Description

Technical Field

[0001] The utility model relates to the technical field of galvanizing processing, in particular to a thickness uniformity control mechanism for an acidic rolling galvanizing coating. Background Art

[0002] Barrel plating is also called drum electroplating. It is a kind of electroplating processing method that places a certain number of small parts in a special drum and deposits various metal or alloy coatings on the surface of the parts by indirect conduction in a rolling state to achieve surface protection, decoration and various functional purposes. Barrel plating is suitable for the electroplating of small parts that cannot or should not be installed due to factors such as shape and size. The pre-plating treatment generally includes the following basic contents: degreasing, rust removal, oxide scale removal, etching, pickling, activation, grinding, polishing, rolling, sandblasting, local insulation, cleaning, preheating, and adding auxiliary electrodes. The small parts to be installed are loaded into the drum. The parts rely on their own gravity to tightly press the cathode conductive device in the drum to ensure that the current required for the parts to be plated can be transmitted smoothly. Then, the drum rotates at a certain speed and in a certain direction. The parts keep rolling and falling after being rotated in the drum. At the same time, the main metal ions are reduced to metal coating on the surface of parts after being affected by the electric field. Fresh solution outside the drum is continuously added to the drum through countless small holes on the drum wall, and the old solution in the drum and the hydrogen generated during the electroplating process are also discharged from the drum through these small holes.

[0003] However, the roller plating barrel in the existing roller plating device is generally fixed, and the roller plating barrel of appropriate capacity cannot be replaced according to the number of parts to be plated, resulting in an excessive number of parts to be plated and uneven thickness of the galvanized layer after roller plating, which affects the quality of the galvanizing processing of parts. Utility Model Content

[0004] The utility model aims to provide a thickness uniformity control mechanism for acidic zinc-roll plating to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an acid barrel galvanizing coating thickness uniformity control mechanism, comprising a main structure and a driving structure, wherein the driving structure is fixed to the outer wall of the main structure;

[0006] The main structure includes a roller plating box, the outer walls of both sides of the roller plating box are fixedly connected with lifting columns, the top of the lifting columns is fixedly connected with a first drive motor, the output end of the first drive motor is fixedly connected with a screw, the outer surface of the screw is threadedly connected with a connecting rod, the bottom of the connecting rod is fixedly connected with a fixing frame, the inner wall of the fixing frame is clamped with a mounting plate, and the outer wall of the mounting plate is rotatably connected to a roller plating barrel.

[0007] Preferably, a lifting slot is formed on the outer surface of the lifting column, and an end of the screw rod away from the first drive motor passes through the lifting column and extends into the lifting slot.

[0008] Preferably, a fixing groove is formed on the inner wall of the fixing frame, a fixing block is arranged inside the fixing groove, and the top of the fixing block is semicircular.

[0009] Preferably, a return spring is fixedly connected to the inner bottom wall of the fixing groove, and the top of the return spring is fixedly connected to the bottom of the fixing block.

[0010] Preferably, a positioning groove is provided on the outer wall of the mounting plate, and the shape and size of the positioning groove are matched with the fixing groove.

[0011] Preferably, the driving structure includes a second driving motor, the output end of the second driving motor is fixedly connected to a driving gear, the outer surface of the driving gear is meshed with a driven gear, the outer wall of the driven gear is fixedly connected to a rotating rod, and the outer wall of the rotating rod is fixedly connected to a roller.

[0012] Preferably, one end of the rotating rod away from the driven gear passes through the roller plating box and is rotatably connected to the roller plating box through a bearing, and the outer wall of the roller is in contact with the outer surface of the roller plating barrel.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] First, the utility model starts the first driving motor to drive the screw to rotate, and the rotating screw drives the connecting rod to move. The displaced connecting rod moves the fixed frame upward, and also drives the barrel to be lifted out of the barrel plating box body, and the mounting plate is moved upward so that the fixed block is squeezed and retracted into the fixed groove, thereby releasing the fixation of the mounting plate and the limit of the barrel plating barrel. When the staff replaces the barrel plating barrel with a suitable capacity according to the number of parts to be plated, the mounting plate is installed in the fixed frame. After the fixing groove is aligned with the positioning groove, the reset spring gives the fixing block an outward force, and the fixing block is stuck in the positioning groove to complete the replacement of the barrel plating barrel. This makes it easy for the staff to replace the barrel plating barrel, avoiding the problem that the capacity of the barrel plating barrel cannot be replaced, resulting in too many parts to be plated and uneven thickness of the galvanized layer after barrel plating.

[0015] Second, the utility model starts the second driving motor to make the driving gear drive the meshing driven gear to rotate, and the rotating driven gear drives the rotating rod to rotate, and also drives the roller to roll, and the rolling roller drives the barrel in contact with it to rotate, thereby avoiding the accumulation of barrel-plated parts in the barrel, causing uneven barrel plating on the surface of the barrel-plated parts.
