[0024] According to an embodiment of the present utility model, an aluminum alloy anodizing device with a stirring function is provided.

[0025] Embodiment 1;

[0026] As Figures 1-5 shown, the aluminum alloy anodizing device with a stirring function according to an embodiment of the present utility model includes a tank structure 1. The tank structure 1 includes an oxidation tank 101, a tank bottom 102, and an arc groove 103. The inner bottom end of the oxidation tank 101 is the tank bottom 102, and the arc groove 103 is provided on the periphery of the oxidation tank 101. The periphery of the oxidation tank 101 is the tank wall. A guide structure 2 is installed on the tank wall, a paddle structure 5 is connected to the guide structure 2, a transmission structure 3 is installed on the oxidation tank 101, one-way air holes 4 are evenly distributed on the tank bottom 102, and the one-way air holes 4 distributed on the tank bottom 102 of the tank structure 1 are connected to a compressed air supply device, so that the one-way air holes 4 regularly and quantitatively introduce air bubbles into the electrolyte, which can disturb the liquid flow and prevent debris from depositing while disturbing the liquid flow. The guide structure 2 and the paddle structure 5 cooperate with the transmission structure 3 to realize the annular flow guidance of the electrolyte in the oxidation tank 101, and improve the uniformity of the electrolyte.

[0027] The guiding structure 2 includes a connecting block 201, a clamping block 202, a fixing bolt 203, a through-hole 204, a limiting block 205, and a hinge seat 206. A clamping block 202 is fixedly arranged on one side of the connecting block 201. A threaded hole is formed in the clamping block 202, and a fixing bolt 203 is screwed in the threaded hole. A through-hole 204 is formed in the connecting block 201, and a guiding wire is threaded through the through-hole 204. A limiting block 205 is fixedly arranged on the guiding wire. A hinge seat 206 is arranged on the other side of the connecting block 201. The hinge seat 206 is rotatably connected to the connecting block 201. The hinge seat 206 is fixedly installed on the groove wall of the groove body structure 1. The guiding structures 2 are evenly distributed on the groove wall. At the same time, the guiding structure 2 is also installed on the arc groove 103. The orientations of the guiding paddles connected by the guiding structures 2 are the same. The guiding wire threaded through the through-hole 204 cooperates with the limiting block 205, so that when the guiding wire is pulled, it will drive the connecting block 201 and the guiding paddle to rotate on the hinge seat 206 through the limiting block 205, thereby generating a directional guiding effect on the electrolyte.

[0028] The transmission structure 3 includes a first motor 301, a first transmission rod 302, a first winding wheel 303, a second motor 304, a second transmission rod 305, a second winding wheel 306, and a fixed block 307. The driving end of the first motor 301 is drivingly connected to the first transmission rod 302, and the first winding wheel 303 is fixedly connected to the first transmission rod 302. A second motor 304 is provided on one side of the first motor 301. The driving end of the second motor 304 is drivingly connected to the second transmission rod 305, and the second winding wheel 306 is fixedly connected to the second transmission rod 305. The first motor 301 is fixedly connected to the fixed block 307, and the second motor 304 is fixedly installed on the fixed block 307. The fixed block 307 is fixedly installed on the oxidation tank 101. The first motor 301 and the second motor 304 are matched and driven with each other. The first motor 301 is driven forward to drive the first transmission rod 302 and the first winding wheel 303 to wind. One end of the guiding wire is fixedly connected to the first winding wheel 303, and the guiding wire can be wound. When the first winding wheel 303 winds, the guiding wire drives the guiding paddle to rotate forward, so that the concave surface 501 of the paddle body generates a positive flow guiding effect on the liquid. The other end of the guiding wire is connected to the second winding wheel 306. When the second winding wheel 306 winds the guiding wire driven by the second motor 304, it pulls the guiding wire in the reverse direction. The first winding wheel 303 will release the wire. The reverse pulling of the guiding wire will cause the guiding paddle to rotate in the reverse direction and reset. Due to the convex surface design of the convex surface 502 of the paddle body, the resistance to the disturbance of the liquid is less than that of the concave surface 501 of the paddle body during the forward transmission. At the same time, the guiding paddle is made of glass fiber reinforced plastic and has a certain flexibility itself. During the reverse transmission process, the convex surface 502 of the paddle body will be deformed by the force, further reducing the force-bearing area of the liquid guiding and reducing the resistance. Therefore, when the flow guiding effect of the forward transmission is greater than that of the reverse transmission, the electrolyte will flow in the direction of the forward flow guiding. Because the guiding structure 2 is evenly distributed on the tank wall, the electrolyte will flow in a circular pattern in the oxidation tank 101.

[0029] The paddle body structure 5 includes a paddle body concave surface 501, a paddle body convex surface 502, and a docking hole 503. The paddle body concave surface 501 is formed on one side of the guiding paddle, and the other side of the guiding paddle is the paddle body convex surface 502. The docking hole 503 is formed on the guiding paddle. The clamping block 202 is fixedly connected to the guiding paddle through the fixing bolt 203 passing through the docking hole 503. The material of the guiding paddle is glass fiber reinforced plastic.

[0030] In order to facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0031] In summary, by means of the above technical solution of the present utility model, the unidirectional air holes 4 distributed at the bottom 102 of the tank body structure 1 are connected to a compressed air supply device, so that the unidirectional air holes 4 regularly and quantitatively introduce air bubbles into the electrolyte, which can prevent debris deposition while disturbing the liquid flow. The guiding structure 2 and the paddle structure 5 cooperate with the transmission structure 3 to realize the annular flow guiding of the electrolyte in the oxidation tank 101, improving the uniformity of the electrolyte. The guiding structure 2 is evenly distributed on the tank wall, and at the same time, the arc-shaped groove 103 is also provided with the guiding structure 2. The orientations of the guiding paddles connected by the guiding structure 2 are the same. The guiding wire passing through the through-hole 204 cooperates with the limiting block 205, so that when the guiding wire is pulled, it will drive the connecting block 201 and the guiding paddle to rotate on the hinge seat 206 through the limiting block 205, thereby generating a directional guiding effect on the electrolyte. The first motor 301 and the second motor 304 are matched and driven with each other. The first motor 301 is driven in the forward direction, so that it drives the first transmission rod 302 and the first reel 303 to wind up. One end of the guiding wire is fixedly connected to the first reel 303, and the guiding wire can be wound up. When the first reel 303 winds up, the guiding wire will drive the guiding paddle in the forward direction, so that the concave surface 501 of the paddle generates a forward guiding effect on the liquid. The other end of the guiding wire is connected to the second reel 306. When the second reel 306 winds up the guiding wire driven by the second motor 304, it pulls the guiding wire in the reverse direction, and the first reel 303 will release the wire. When the guiding wire is pulled in the reverse direction, the guiding paddle will be driven in the reverse direction to reset. Since the convex surface design of the convex surface 502 of the paddle has a smaller resistance to the disturbance of the liquid than the concave surface 501 of the paddle driven in the forward direction, and at the same time, the guiding paddle is made of glass fiber reinforced plastic and has a certain flexibility, the convex surface 502 of the paddle will be deformed under force during the reverse transmission process, further reducing the force-bearing area with the liquid guiding and reducing the resistance. Therefore, when the guiding effect in the forward direction is greater than the guiding effect in the reverse direction, the electrolyte will flow in the direction of the forward guiding. Because the guiding structure 2 is evenly distributed on the tank wall, the electrolyte will flow annularly in the oxidation tank 101.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
