Description

Technical Field

[0001] The utility model relates to the field of electroplating equipment, in particular to a filtering mechanism and small electroplating equipment. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to make a layer of metal film adhere to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance and enhancing aesthetics. The outer layer of many coins is also electroplated. When the plating solution is added to the electroplating equipment after preparation, residual metal particles will enter the electroplating equipment along with the plating solution. Therefore, it is necessary to filter out useless metal impurities in the plating solution.

[0003] The prior art has the following problems: the filter mechanism of the traditional electroplating equipment is easily clogged, resulting in reduced filtering efficiency, and the traditional cleaning method is only to clean the filter screen with a cleaning brush, which has a single cleaning method and poor cleaning effect. Utility Model Content

[0004] The purpose of the utility model is to provide a filtering mechanism and a small electroplating device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filtering mechanism, the filtering mechanism includes a gantry and a cleaning assembly, the top of the gantry is fixedly connected to two cylinders, a lifting ring is fixedly connected between the output ends of the two cylinders, the middle part of the lifting ring is fixedly connected to a liquid inlet pipe, the bottom end of the liquid inlet pipe is provided with a filtering assembly, the bottom of the lifting ring is fixedly connected to a lifting cylinder, two slide grooves are provided on both sides of the inner wall of the lifting cylinder, an annular groove is provided on the top of the inner wall of the lifting cylinder, the cleaning assembly is arranged on the outside of the liquid inlet pipe, and the cleaning assembly includes a slider slidably connected to the inside of the two slide grooves, the slider is fixedly connected to the outer top end of the rotating cylinder, the surface of the rotating cylinder is provided with a spiral groove, and the outer bottom end of the rotating cylinder is fixedly connected to an L-shaped cleaning brush.

[0006] Preferably, the spiral groove has one turn, and a fixing rod is inserted into the middle of the spiral groove, and the fixing rod is L-shaped.

[0007] Preferably, the rotating cylinder is sleeved on the outside of the liquid inlet pipe, and the inner diameter of the rotating cylinder is consistent with the outer diameter of the liquid inlet pipe.

[0008] Preferably, the filter assembly comprises a filter cartridge fixedly connected to the bottom end of the liquid inlet pipe, a side surface of the filter cartridge is provided with a plurality of filter holes, and the plurality of filter holes are equiangularly distributed on the outer surface of the filter cartridge.

[0009] Preferably, three connecting rods and a conical plate are respectively fixedly connected between the inner walls of the filter cartridge, the three connecting rods are connected via a blocking plate, the conical plate is located below the blocking plate, and a through hole is opened in the middle of the conical plate.

[0010] Preferably, two fixing blocks are fixedly connected to the bottom of the inner wall of the filter cartridge, a plug-in block is inserted in the middle of the two fixing blocks, the plug-in block is fixedly connected to the top edge of the bottom plate, and a locking screw is inserted in the middle of the plug-in block.

[0011] A small electroplating device comprises an electroplating device body, on which a filtering mechanism as described above is installed.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the lifting cylinder is driven downward by the cylinder, and the fixed rod is fixedly connected to the inner top of the electroplating equipment body. At this time, the rotating cylinder will remain in place under the obstruction of the fixed rod, so that the rotating cylinder and the lifting cylinder can move relative to each other. Therefore, when the lifting cylinder descends, the slider will slide upward in the slide groove. When the lifting cylinder descends to a certain position, the slider will enter the annular groove, and the cylinder continues to push the lifting cylinder down. At this time, the opening diameter at the top of the lifting cylinder is smaller than the outer diameter of the rotating cylinder. At this time, under the action of the fixed rod and the spiral groove, the rotating cylinder starts to rotate. When the rotating cylinder rotates, it will drive the L-shaped cleaning brush to clean the filter holes on the side of the filter cylinder to prevent the filter cylinder from being blocked and causing the filtration efficiency to decrease. The filter cylinder is pushed down by the cylinder to make the filter cylinder descend into the electroplating liquid. At this time, the electroplating liquid will flow inward from the outside of the filter cylinder, forming a reverse impact force to flush out the impurities in the filter holes and drop them to the bottom of the inner side of the filter cylinder for collection. The filter holes are cleaned at the same time with the L-shaped cleaning brush. The double cleaning method can better clean the filter cylinder and achieve better cleaning effect.
