Technical Field
[0001] This utility model belongs to the field of electroplating solution technology, specifically relating to a cyanide-free electroplating solution mixing device. Background Technology
[0002] Electroplating solutions are liquids that can expand the range of cathode current densities for metals, improve the appearance of the coating, and increase the stability of the solution against oxidation. There are countless types of electroplating solutions; more than ten have been used in manufacturing experiments. Four commonly used plating solutions in production are cyanide zinc plating, zincate zinc plating, chloride zinc plating, and sulfate zinc plating. The numerous plating solutions evolved from these variations, differing only slightly in their main salt and other components.
[0003] Most existing cyanide-free electroplating solution mixing devices are not very practical. They cannot achieve circulating stirring, have low stirring efficiency, and because the electroplating solution contains deposited metals, it needs to be crushed. Furthermore, the stirring effect on the electroplating solution that accumulates at the bottom of the device is not good, which can easily lead to poor final mixing effect. The problem that this device addresses is how to achieve circulating stirring, improve stirring efficiency, and improve the final mixing effect of cyanide-free electroplating solution. Utility Model Content

In addition, the stirring rod and grinding rod crush the sediment in the electroplating solution, which effectively improves the mixing effect. The drive motor drives the rotation of the second spiral blade, which can convey the electroplating solution to the discharge pipe for discharge. The device has high practicality.

[0020] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides the following technical solution: a cyanide-free electroplating solution mixing device, including a mixing cylinder 1, a servo motor 2 fixedly mounted on the top of the mixing cylinder 1, a rotating shaft fixedly mounted on the output end of the servo motor 2, a main gear 4 and a first helical blade 6 fixedly mounted on the surface of the rotating shaft, and the first helical blade 6 being disposed below the main gear 4; a secondary gear 5 and a gear ring 3 are rotatably mounted on the inner side of the top of the mixing cylinder 1, and the main gear 4 and the secondary gear 5 are disposed on the inner side of the gear ring 3, and the main gear 4 and the secondary gear 5 are meshed and connected, and the secondary gear 5 is meshed and connected to the gear ring 3. A connecting rod 7 is fixedly installed at the bottom, and a conveying cylinder 8 is fixedly installed at the bottom of the connecting rod 7. The first spiral blade 6 is located inside the conveying cylinder 8. A stirring rod 9 is fixedly installed on the surface of the conveying cylinder 8. A grinding rod 10 is fixedly installed inside the mixing cylinder 1. An installation plate 11 is fixedly installed on the left side of the mixing cylinder 1. A drive motor 12 is fixedly installed on the surface of the installation plate 11. A second spiral blade 13 is fixedly installed on the drive motor 12 through the rotating shaft at the output end. A feed pipe 14 is fixedly installed on the left side of the top of the mixing cylinder 1. A discharge pipe 15 is fixedly installed on the right side of the mixing cylinder 1.
[0022] The rotation shaft at the output end of the servo motor 2 drives the main gear 4 and the first spiral blade 6 to rotate. Since the main gear 4 meshes with the secondary gear 5, and the secondary gear 5 meshes with the gear ring 3, the gear ring 3 and the first spiral blade 6 rotate in opposite directions, which in turn drives the rotation of the stirring rod 9. The first spiral blade 6 conveys the cyanide-free electroplating solution upwards, and then it flows down from above the conveying cylinder 8, so that the cyanide-free electroplating solution in the mixing cylinder 1 is circulated and stirred. In addition, the stirring rod 9 and the grinding rod 10 crush the sediment in the electroplating solution, which effectively improves the mixing effect. The rotation shaft at the output end of the drive motor 12 drives the rotation of the second spiral blade 13, which can convey the electroplating solution to the discharge pipe 15 for discharge. The device is highly practical. The addition of a confluence hole 16 on the surface of the stirring rod 9 helps to reduce the resistance when the stirring rod 9 rotates and reduce the load on the servo motor 2. The controller 20 is fixedly installed on the right side of the servo motor 2 and is electrically connected to the servo motor 2, which facilitates better control according to the usage. The rotation amplitude and switching of the servo motor 2 make the stirring more controllable, increasing the comfort of using the device. The sealing cap 17 installed on the top thread of the feed pipe 14 makes it easy to cover the feed pipe 14 and prevent external impurities from entering and contaminating the electroplating solution. The handle 18 makes it easier to put on and take off the sealing cap 17. The solenoid valve 19 is fixedly installed on the surface of the discharge pipe 15, which makes it easier to control the discharge of the electroplating solution and increases the practicality of the device structure. The observation window 21 is opened on the surface of the mixing cylinder 1, and the glass plate 22 is fixedly installed on the surface of the observation window 21. The glass plate 22 is transparent, which makes it easier for the user to observe the operation inside the mixing cylinder 1, increasing the comfort of using the device. The support legs 23 make it easier to stabilize the mixing cylinder 1, and the anti-slip pads 24 increase the friction, making the device more stable and increasing the stability of the device. All electrical equipment in this device is powered by an external power supply.
[0023] In one aspect of this embodiment, the arrangement of the flow-collecting hole 16 on the surface of the stirring rod 9 facilitates the reduction of resistance when the stirring rod 9 rotates, thereby reducing the load on the servo motor 2. The arrangement of the controller 20 fixedly installed on the right side of the servo motor 2 and electrically connected to the servo motor 2 facilitates better control of the rotation amplitude and switching of the servo motor 2 according to the usage situation, making the stirring more controllable and increasing the comfort of using the device.
[0024] In one aspect of this embodiment, the provision of a sealing cap 17 threaded onto the top of the feed pipe 14 facilitates the covering of the feed pipe 14, preventing external impurities from entering and contaminating the electroplating solution. The provision of a handle 18 facilitates the easier placement and removal of the sealing cap 17. The provision of a solenoid valve 19 fixedly mounted on the surface of the discharge pipe 15 facilitates better control of the discharge volume of the electroplating solution, increasing the practicality of the device structure.
[0025] In one aspect of this embodiment, an observation window 21 is provided on the surface of the mixing cylinder 1. A glass plate 22 is fixedly installed on the surface of the observation window 21, and the glass plate 22 is transparent. This allows the user to better observe the operation inside the mixing cylinder 1 through the observation window 21, increasing the comfort of using the device. The support legs 23 help to better stabilize the mixing cylinder 1, while the anti-slip pads 24 increase the friction, making the device more stable and increasing its stability.
[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
