Description

Technical Field

[0001] This utility model relates to an electroplating device, specifically a linear electroplating device for thick plates and strips of precious metals. Background Technology

[0002] Electroplated steel sheets are protective plates on which a layer of metal is plated onto the surface of a steel sheet through electrolysis. Electroplated sheets have demonstrated their unique value in numerous industrial sectors.

[0003] Electroplated steel sheets are widely used in various industries, including the home appliance industry (such as the outer shells of refrigerators and washing machines), the automotive industry (as the main material for car bodies and doors), the construction industry (for the decoration and protection of roofs and wall panels), and the manufacturing of machinery and equipment (such as the manufacture of motors and compressors).

[0004] Its notable characteristics include excellent rust resistance, effectively resisting moisture and corrosion; superior appearance, enhancing the overall aesthetics of the product; high strength, ensuring product stability during use; and good machinability, facilitating bending, stamping, and other processing operations. These properties make electroplated steel an indispensable and preferred material in many industrial fields.

[0005] Currently, in the process of electroplating sheet and strip, a layer of electroplating solution needs to be applied to the surface of the metal sheet and strip. Since there are strict requirements for the electroplating area, it is necessary to strictly control the immersion area of ​​the solution. However, since the solution is fluid, it is not easy to strictly control its immersion range in industrial continuous production, which often causes deviations in the electroplating area.

Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0045] Please see Figures 1-7 As an embodiment of the present utility model, the thick plate strip precious metal linear electroplating device includes a base plate 2 and a conveyor belt mechanism arranged on the base plate 2 along the length direction of the base plate 2;

[0046] Spraying mechanisms for spraying chemicals onto the electroplating area on the plate strip 4 are symmetrically arranged on both sides of the plate strip 4.

[0047] The conveyor belt mechanism is used to drive the plate 4 to be electroplated to move in a straight line along the length of the base plate 2, and to cover the non-electroplated areas on the plate 4 to be electroplated.

[0048] In this embodiment, the spraying mechanism can spray chemicals on the areas of the plate 4 that need to be electroplated, and the conveyor belt mechanism can shield the non-electroplated areas to prevent the non-electroplated areas from being accidentally sprayed with chemicals and electroplated.

[0049] In addition, the conveyor belt mechanism can not only control the front and rear tension, and thus the contact force, but also control the left and right tension, thereby ensuring the straightness of the plate belt 4 to be electroplated.

[0050] As a further embodiment of this utility model, the conveyor belt mechanism includes two sets of synchronous belt structures, namely a first synchronous belt structure and a second synchronous belt structure;

[0051] The first synchronous belt structure includes two pulleys that are rotatably arranged along the length of the base plate 2, and the first synchronous belt structure is located on one side of the plate to be electroplated 4.

[0052] The second synchronous belt structure also includes two pulleys that are rotatably arranged along the length of the base plate 2, and the second synchronous belt structure is located on the other side of the plate to be electroplated 4;

[0053] In the first synchronous belt structure, the two pulleys are connected by two shielding belts 7 distributed vertically, and there is a gap between the two shielding belts 7.

[0054] In the second synchronous belt structure, the two pulleys are connected by two additional vertically distributed shielding belts 7, and there is also a gap between the two shielding belts 7.

[0055] In this embodiment, the gaps formed between the upper and lower shielding strips 7 allow the electroplating area on the plate 4 to be exposed, so that the chemical solution can be effectively sprayed onto it. Meanwhile, the non-electroplated areas on the plate 4 are shielded by the presence of the shielding strips 7, ensuring that the chemical solution does not soak into them.

[0056] As a further embodiment of this utility model, one of the pulleys in the first synchronous belt structure is a driving pulley, which is rotatably mounted on the base plate 2; the other pulley is rotatably mounted on a set of left and right tension control structures 10.

[0057] The left and right tension control structure 10 includes a base disposed on the base plate 2, a guide rod disposed on the base, and a mounting seat slidably disposed on the guide rod, and the pulley is rotatably disposed on the mounting seat;

[0058] An adjusting screw parallel to the guide rod is rotatably mounted on the base, and the adjusting screw is threadedly connected to the mounting seat.

[0059] In this embodiment, since one of the pulleys is rotatably mounted on the base plate 2 and its position is fixed, the mounting seat can be adjusted along the length of the base plate 2 by rotating the adjusting screw, thereby adjusting the distance between the two pulleys and ultimately achieving left and right tension control adjustment of the shielding belt 7 on the first synchronous belt structure.

[0060] As a further embodiment of this utility model, the second synchronous belt structure is mounted on the adjusting plate 14, and the adjusting plate 14 is set on the base plate 2 by the front and rear tension control structure 11.

[0061] The front and rear tension control structure 11 is the same as the left and right tension control structure, including a base, a guide rod set on the base, and a mounting seat slidably set on the guide rod. An adjusting screw parallel to the guide rod is also rotatably installed on the base, and the adjusting screw is threadedly connected to the mounting seat.

[0062] The base is fixedly connected to the base plate 2, and the adjusting plate 14 is fixedly connected to the mounting base;

[0063] In the second synchronous belt structure, one of the pulleys is the driving pulley, which is rotatably mounted on the adjusting plate 14, and the other pulley is rotatably mounted on another set of left and right tension control structures 10;

[0064] The base of the left and right tension control structure 10 is fixedly connected to the adjustment plate 14.

[0065] In this embodiment, the distance between the second synchronous belt structure and the first synchronous belt structure can be adjusted by the adjusting screw in the front and rear tension control structure 10 to accommodate electroplating plates 4 of different thicknesses, thereby achieving the effect of front and rear tension control.

[0066] Similarly, since one of the pulleys in the second synchronous belt structure is mounted on another set of left and right tension control structures 10, the left and right tension of the shielding belt 7 connected by the two pulleys in the second synchronous belt structure can also be adjusted.

[0067] As a further embodiment of this utility model, the driving pulley in the first synchronous belt structure and the driving pulley in the second synchronous belt structure are connected by a gear set.

[0068] The gear set includes a driving gear 13 coaxially connected to one of the driving pulleys and a driven gear 12 coaxially connected to the other driving pulley, wherein the driving gear 13 and the driven gear 12 mesh with each other.

[0069] In this embodiment, the two synchronous belt structures connected by the gear set ensure that the shielding belts 7 located on both sides of the plate to be electroplated 4 are conveyed in the same direction.

[0070] As a further embodiment of this utility model, an auxiliary motor 6 is also provided on one side of the base plate 2, and the output end of the auxiliary motor 6 is connected to one of the driving pulleys through a transmission belt.

[0071] A set of conductive seats 3 is provided at each end of the base plate 2. Multiple guide wheels are rotatably mounted on the conductive seats 3, and a channel is formed between the multiple guide wheels for the plate strip 4 to be electroplated to roll through.

[0072] In this embodiment, the auxiliary motor 6 can provide power to the two sets of synchronous belt structures, and at the same time ensure that the running speed of the shielding belts 7 on both sides of the plate to be electroplated 4 is always equal.

[0073] The conductive seat 3 can guide and constrain the front and rear ends of the plate strip 4 to be electroplated as it passes through the electroplating device, preventing the plate strip 4 from deforming before entering the electroplating device and after exiting the electroplating device.

[0074] As a further embodiment of this utility model, the spraying mechanism includes water bags 9 symmetrically arranged on both sides of the plate strip 4 to be electroplated, one of the water bags 9 being fixedly installed on the adjusting plate 14, and the other water bag 9 being arranged on the base plate 2.

[0075] In the first synchronous belt structure, the shielding band 7 encloses one of the water bladders 9, and in the second synchronous belt structure, the shielding band 7 encloses the other water bladder 9.

[0076] A set of water outlets 901 are provided at the center of the two water bags 9 facing each other along the length of the bottom plate 2, and the water outlets 901 are directly opposite the gap;

[0077] The water bladder 9 is connected to the water supply pipe 8.

[0078] In this embodiment, since the inner side of the shielding band 7 in the two sets of synchronous structures encloses the water bag 9, and the outer side of the shielding band 7 in the two sets of synchronous structures clamps and covers the plate 4 to be electroplated, and the water outlet 901 is directly facing the gap, the liquid in the water bag 9 will only spray onto the plate 4 to be electroplated at the gap, while the sides of other areas are blocked by the shielding band 7 respectively.

[0079] As a further embodiment of this utility model, a support plate is provided on the conductive base 3, the guide wheel is rotatably mounted on the support plate, a slide rod is vertically mounted on the conductive base 3, a top plate is provided at the top of the slide rod, and a height adjustment screw is rotatably mounted on the top plate, the height adjustment screw being threadedly connected to the support plate.

[0080] In this embodiment, rotating the height adjustment screw can drive the threaded pallet to rise and fall, thereby driving the guide wheel to rise and fall, so as to adapt to different plate electroplating heights.

[0081] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
