[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and Figure 4-5The electroplating solution mixing and stirring device of this embodiment includes a base 1, a tilting frame 2 rotatably connected to the top of the base 1, a stirring tank 3 detachably mounted on the outer side of the top of the tilting frame 2, a top cover 7 detachably mounted on the top of the stirring tank 3, an outlet pipe 12 mounted at the bottom axis of the stirring tank 3, and feeding mechanisms 9 mounted on the upper and lower sides of the stirring tank 3 for feeding different types of raw materials into the stirring tank 3. The feeding mechanism 9 includes an upper feeding pipe 901 and a lower feeding pipe 902. The upper feeding pipe 901 is located at the top edge of the top cover 7, and the lower feeding pipe 902 is located at the outlet pipe 12. On the side, an inner flow pipe 904 is fixedly connected inside the axis of the liquid outlet pipe 12. The lower feed pipe 902 is connected to the inner flow pipe 904. An annular spray pipe 905 is arranged around the liquid outlet pipe 12 on the inner bottom of the mixing tank 3. The inner flow pipe 904 is connected to the annular spray pipe 905. Several spray holes 907 are evenly opened on the top of the annular spray pipe 905. A motor 8 is fixedly connected to the top center of the top cover 7. A stirring shaft 14 is fixedly connected to the rotating shaft of the motor 8. The stirring shaft 14 is coaxial with the mixing tank 3. Several stirring blades 15 are fixedly connected to the lower side of the outer wall of the stirring shaft 14. During feeding, different raw material output pipes are connected to the upper feeding pipe 901 and the lower feeding pipe 902 respectively. The denser raw material is fed into the interior of the mixing tank 3 through the upper feeding pipe 901, and the less dense raw material is fed into the inner flow pipe 904 through the lower feeding pipe 902. Then, the raw material flows into the annular nozzle 905 and is sprayed out from the bottom of the mixing tank 3 through several spray holes 907 at the top of the annular nozzle 905. At this time, the motor 8 is started, which makes the stirring shaft 14 and the stirring blades 15 start to rotate, stirring the mixed raw materials inside the mixing tank 3. During the stirring process, the raw material sprayed out through the spray holes 907 at the top of the annular nozzle 905 can improve the backflow effect at the bottom of the mixing tank 3, thereby making the raw materials more uniformly mixed and improving the electroplating quality of the mixed electroplating solution.

[0024] Please see Figure 3 A shut-off valve 13 is installed in the middle of the outlet pipe 12, and a regulating valve 903 is installed in the middle of the lower feed pipe 902. Several guide vanes 906 are fixedly connected around the inner wall of the inner flow pipe 904 between the outer wall and the inner wall of the outlet pipe 12. The input flow rate of the raw material can be adjusted by the regulating valve 903, thereby adjusting the concentration of the electroplating solution. When stirring, the shut-off valve 13 is closed to seal the outlet pipe 12. After stirring is completed, the shut-off valve 13 is opened, so that the stirred electroplating solution flows out along the flow channel between the outlet pipe 12 and the inner flow pipe 904. The guide vanes 906 can divert and guide the outflow of the electroplating solution.

[0025] Please see Figure 2A telescopic rod 4 is rotatably connected to the middle of the side of the tilting frame 2 away from the mixing tank 3. A slider 5 is rotatably connected to the other end of the telescopic rod 4. The slider 5 is slidably connected to the top of the base 1. A hydraulic cylinder 11 is horizontally installed at the bottom of the base 1. The piston rod of the hydraulic cylinder 11 is fixedly connected to the slider 5. The hydraulic cylinder 11 is located directly below the telescopic rod 4. Several support seats 10 are fixedly connected to the top of the side of the tilting frame 2 away from the mixing tank 3. After the electroplating solution is discharged from the mixing tank 3 after stirring, the slider 5 is driven by the hydraulic cylinder 11 to move away from the tilting frame 2. When the slider 5 moves, it drives the telescopic rod 4 rotatably connected to its top to rotate around the middle of the side wall of the tilting frame 2, generating a pulling force on the tilting frame 2. This causes the tilting frame 2 to start rotating around its connection with the base 1, driving the support seats 10 on the top of the side wall of the tilting frame 2 to move towards the base 1 until the support seats 10 abut against the top of the base 1. At this time, the tilting frame 2 rotates 90°, bringing the mixing tank 3 to a horizontal position, which facilitates the disassembly and cleaning of the mixing tank 3.

[0026] The outer wall of the mixing tank 3 is surrounded by a heating layer 6, with an inlet and an outlet respectively located at the top and bottom of the outer side of the heating layer 6. By providing the heating layer 6, heat-conducting liquid can be introduced into the cavity between the mixing tank 3 and the heating layer 6 through the inlet during mixing, thereby regulating the temperature of the electroplating solution inside the mixing tank 3.

[0027] Working principle: During feeding, different raw material output pipes are connected to the upper feeding pipe 901 and the lower feeding pipe 902 respectively. The denser raw material is fed into the mixing tank 3 through the upper feeding pipe 901, while the less dense raw material is fed into the inner flow pipe 904 through the lower feeding pipe 902, and then flows into the annular nozzle 905. The material is then sprayed out from the bottom of the mixing tank 3 through several nozzles 907 at the top of the annular nozzle 905. At this time, the motor 8 is started, causing the stirring shaft 14 and stirring blades 15 to rotate, stirring the mixed raw materials inside the mixing tank 3. During the stirring process, the raw material sprayed through the nozzles 907 at the top of the annular nozzle 905 can raise the bottom of the mixing tank 3. The reflux effect makes the raw materials more uniformly mixed, thereby improving the electroplating quality of the mixed electroplating solution; the input flow rate of the raw materials can be adjusted by regulating valve 903, thereby adjusting the concentration of the electroplating solution; during stirring, the shut-off valve 13 is closed to seal the outlet pipe 12, and after stirring is completed, the shut-off valve 13 is opened, so that the stirred electroplating solution flows out along the flow channel between the outlet pipe 12 and the inner flow pipe 904, and the flow guide plate 906 can divert and guide the outflow of the electroplating solution; by setting the heating layer 6, during stirring, heat transfer liquid can be introduced into the cavity between the stirring tank 3 and the heating layer 6 through the liquid inlet, thereby regulating the temperature of the electroplating solution inside the stirring tank 3.

[0028] After the electroplating solution is discharged from the mixing tank 3 after stirring, the hydraulic cylinder 11 drives the slider 5 to move away from the flipping frame 2. When the slider 5 moves, it drives the telescopic rod 4 connected to its top to rotate around the middle of the side wall of the flipping frame 2, generating a pulling force on the flipping frame 2. This causes the flipping frame 2 to start rotating around the connection point with the base 1, driving the support seat 10 at the top of the side wall of the flipping frame 2 to move towards the base 1 until the support seat 10 abuts against the top of the base 1. At this time, the flipping frame 2 rotates 90°, bringing the mixing tank 3 to a horizontal position, which facilitates the disassembly and cleaning of the mixing tank 3.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
