Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and in particular to a solution stirring device for anodizing treatment. Background Technology

[0002] Anodizing is the electrochemical oxidation of metals or alloys. It is the process by which an oxide film is formed on aluminum products under the action of an applied current in the appropriate electrolyte and under specific process conditions. Unless otherwise specified, anodizing usually refers to sulfuric acid anodizing.

[0003] The electrolysis required for anodizing typically uses liquid sulfuric acid, chromic acid, oxalic acid, etc., as the positive electrode. During the preparation of the electrolyte, sulfuric acid, chromic acid, oxalic acid, etc., need to be diluted. At this time, a stirring device is required. However, when using the existing stirring device, the solution needs to be filled to a certain level before stirring, and the solution needs to be discharged after stirring is completed before the next batch is filled and stirred. The waiting time is long, which reduces the stirring effect. Therefore, a solution stirring device for anodizing is needed to meet the requirements. Utility Model Content

[0004] The purpose of this invention is to provide a solution stirring device for anodizing treatment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solution stirring device for anodizing treatment, comprising a tank body, a motor mounted on the tank body, a rotating shaft connected to the output end of the motor, the rotating shaft being rotatably connected to the tank body, a connecting block mounted on the bottom end of the rotating shaft, a plurality of first connecting rods rotatably connected to the outer walls of the connecting block, a sliding block slidably connected to the outer wall of the rotating shaft, a plurality of second connecting rods rotatably connected to the outer wall of the sliding block, each second connecting rod being rotatably connected to a corresponding first connecting rod, electric telescopic rods mounted on both outer walls of the tank body, a common connecting rod connected to the telescopic shafts of two electric telescopic rods, two sliding rods connected to the bottom end of the connecting rods, the two sliding rods being slidably connected to the top end of the tank body, a common piston disc connected to the bottom end of the two sliding rods, the piston disc being slidably connected to the rotating shaft, a sealing ring fitted on the outer wall of the piston disc, a first one-way valve body mounted on the piston disc, an inlet pipe mounted on the top end of the tank body, an outlet pipe mounted on one side of the bottom end of the tank body, and a second one-way valve body mounted inside the outlet pipe.

[0006] Preferably, a first rubber ring is embedded in the top of the tank, and the rotating shaft is rotatably connected inside the first rubber ring.

[0007] Preferably, a first spring is sleeved on the outer wall of the rotating shaft, with one end of the first spring connected to the connecting block and the other end connected to the sliding block.

[0008] Preferably, a rotating groove is provided on one end of the second connecting rod, and the first connecting rod is rotatably connected in the rotating groove.

[0009] Preferably, a second rubber ring is embedded in the top of the tank, and the slide rod is slidably connected inside the second rubber ring.

[0010] Preferably, a third rubber ring is embedded in the piston disc, and the rotating shaft is rotatably connected within the third rubber ring.

[0011] Preferably, both the first one-way valve body and the second one-way valve body are composed of a first fixed ring, a second fixed ring, a second spring and a conical plug, with the two ends of the second spring connected to the first fixed ring and the conical plug respectively, and the conical plug slidingly fitting within the second fixed ring.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, a motor drives a rotating shaft to rotate, causing the connecting block to rotate accordingly. This, in turn, causes the first and second connecting rods to rotate in a circular motion, thus stirring the electrolyte for anodizing. Furthermore, an electric telescopic rod extends and retracts, connecting the connecting rod and the sliding rod to achieve piston movement of the piston disc within the tank. This allows the piston disc to press down, enabling rapid discharge of the stirred electrolyte. Simultaneously, it allows the electrolyte to be drawn into the space above the piston disc and remain stationary, while the piston disc moves upward, allowing the electrolyte above the piston disc to be discharged into the stirring mechanism at the bottom of the tank. This effectively reduces the electrolyte filling and emptying time in existing technologies and improves stirring efficiency. Attached Figure Description

[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.

[0021] Reference Figure 1-5 A solution stirring device for anodizing treatment includes a tank body 1, a motor 2 mounted on the tank body 1, a rotating shaft 3 connected to the output end of the motor 2, the rotating shaft 3 being rotatably connected inside the tank body 1, a connecting block 4 mounted on the bottom end of the rotating shaft 3, a plurality of first connecting rods 5 rotatably connected to the outer walls of the connecting block 4, a sliding block 6 slidably connected to the outer wall of the rotating shaft 3, and a plurality of second connecting rods 7 rotatably connected to the outer wall of the sliding block 6, each second connecting rod 7 being rotatably connected to a corresponding first connecting rod 5, and electric telescopic rods 8 mounted on both outer walls of the tank body 1. Two electric telescopic rods 8 are connected to the same connecting rod 9 on their telescopic shafts. Two sliding rods 10 are connected to the bottom end of the connecting rod 9. The two sliding rods 10 are slidably connected to the top of the tank body 1. The bottom end of the two sliding rods 10 is connected to the same piston disc 11. The piston disc 11 is slidably connected to the rotating shaft 3. A sealing ring 12 is fitted on the outer wall of the piston disc 11. A first one-way valve body 13 is provided on the piston disc 11. An inlet pipe 14 is provided on the top of the tank body 1. An outlet pipe 15 is provided on one side of the bottom of the tank body 1. A second one-way valve body 16 is provided inside the outlet pipe 15.

[0022] The rotating shaft 3 is driven by motor 2, causing the connecting block 4 to rotate accordingly. This causes the first connecting rod 5 and the second connecting rod 7 to rotate in a circular motion, thus stirring the electrolyte for anodizing. The electric telescopic rod 8 extends and retracts, and through the connection of the connecting rod 9 and the sliding rod 10, the piston disc 11 moves within the tank 1. When the piston disc 11 is pressed down, the first one-way valve 13 closes and the second one-way valve 16 opens, allowing for the rapid discharge of the stirred electrolyte. A one-way valve can be installed at the inlet pipe 14. Simultaneously, a negative pressure is created in the upper space of the piston disc 11, drawing the electrolyte to be stirred from the feeding mechanism connected to the inlet pipe 14. When the piston disk 11 moves upward into the space above the piston disk 11, the first one-way valve body 13 opens and the second one-way valve body 16 closes, discharging the electrolyte to be stirred in the space above the piston disk 11 into the stirring mechanism at the bottom of the tank 1, thereby achieving rapid feeding and effectively reducing the electrolyte filling and discharge time in the prior art. It also enables the stirring device to achieve feeding and discharging effects without stopping the machine, improving stirring efficiency. Through the sliding effect of the sliding block 6 and the rotation effect between the second connecting rod 7 and the first connecting rod 5, the folding effect between the first connecting rod 5 and the second connecting rod 7 is achieved, ensuring the smooth downward movement of the piston disk 11.

[0023] Specifically, in this embodiment, a first rubber ring 17 is embedded in the top of the tank body 1, and the rotating shaft 3 is rotatably connected in the first rubber ring 17, which ensures that the rotating shaft 3 rotates smoothly while improving the sealing of the connection part.

[0024] Specifically, in this embodiment, a first spring 18 is sleeved on the outer wall of the rotating shaft 3. One end of the first spring 18 is connected to the connecting block 4, and the other end is connected to the sliding block 6. After the piston disc 11 moves up, the sliding block 6 automatically rises under the elastic force of the first spring 18, causing the first connecting rod 5 and the second connecting rod 7 to produce a restoration effect.

[0025] Specifically, in this embodiment, a rotating groove 19 is provided on one end of the second connecting rod 7, and the first connecting rod 5 is rotatably connected in the rotating groove 19, so as to realize that the centers of the first connecting rod 5 and the second connecting rod 7 are collinear, thereby improving the overall rigidity and ensuring the rotational stirring effect.

[0026] Specifically, in this embodiment, a second rubber ring 20 is embedded in the top of the tank body 1, and the slide rod 10 is slidably connected in the second rubber ring 20 to ensure that the slide rod 10 slides smoothly and at the same time improves the sealing of the connection part.

[0027] Specifically, in this embodiment, a third rubber ring 21 is embedded in the piston disc 11, and the rotating shaft 3 is rotatably connected in the third rubber ring 21 to ensure the smooth rotation of the rotating shaft 3 and the sliding of the piston disc 11 on the outer wall of the rotating shaft 3.

[0028] Specifically, in this embodiment, the first one-way valve body 13 and the second one-way valve body 16 are both composed of a first fixing ring 22, a second fixing ring 23, a second spring 24 and a conical plug 25. The two ends of the second spring 24 are respectively connected to the first fixing ring 22 and the conical plug 25, and the conical plug 25 is slidably adapted to the second fixing ring 23.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
