Some manufacturers use electrostatic spraying for passivation treatment of aluminum plates, thereby improving product quality. Users can control the paint thickness during the spraying process.

[0003] Existing electrostatic passivation surface treatment equipment applies a coating to the surface of aluminum materials through electrostatic spraying. However, it can only spray one side of the aluminum material at a time. After one side is sprayed, the equipment needs to be stopped and the aluminum material needs to be manually flipped over, which reduces the processing efficiency. Utility Model Content

[0030] (III) Beneficial Effects

[0031] Compared with the prior art, the present invention provides an electrostatic passivation surface treatment device, which has the following beneficial effects:

[0032] This processing equipment boasts improved processing efficiency. One end of the aluminum material is placed against the inner left wall of the fixed frame.

After spraying, motor two rotates the fixed frame 180 degrees via a shaft, flipping the other side of the aluminum material upwards for spraying. This solves the problem of existing processing equipment that can only spray one side of the aluminum material at a time, requiring the device to be paused and the aluminum material manually flipped after one side is sprayed, thus reducing processing efficiency.

[0041] 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.

[0042] Example 1

[0043] See Figure 1-4 An electrostatic passivation surface treatment device includes a main component 1, which includes: a processing frame 11 with a through groove 12 on its top; a processing component 2 disposed on the processing frame 11 and the through groove 12, the processing component 2 including: a rotating shaft 211 symmetrically and rotatably connected to the inner side wall of the processing frame 11; a fixed frame 21 fixedly connected to the opposite end of the rotating shaft 211; a second motor 261 disposed on the outer side wall of the processing frame 11, the output shaft of the second motor 261 being fixedly connected to one of the rotating shafts 211; a cavity 221 symmetrically opened inside the fixed frame 21; a lead screw 22 rotatably connected to one of the cavities 221; and a movable block 23 symmetrically and slidingly. A movable block 23 is threaded to the outside of the lead screw 22 and is movably connected to the cavity 221. A fixed block 24 is fixedly connected to the end of the movable block 23 away from the cavity 221. A pressure sensor 241 is disposed on the side wall of the fixed block 24 away from the movable block 23. A motor 25 is disposed on the outer wall of the fixed frame 21, and the output shaft of the motor 25 is fixedly connected to the lead screw 22. A controller 26 is disposed on the inner wall of the processing frame 11, and the controller 26 is electrically connected to the motor 25, the motor 261, and the pressure sensor 241. A spraying mechanism 27 is disposed on the processing frame 11 and the through groove 12. The spraying mechanism 27 includes: an electric push rod 271, disposed at the top of the processing frame 11; a connecting plate 272, fixedly connected to the output shaft of the electric push rod 271, the connecting plate 272 extending through the through groove 12 into the interior of the processing frame 11; a spray head 273, disposed at the bottom of the connecting plate 272, the electric push rod 271, the spray head 273 and the controller 26 electrically connected; and a material conveying mechanism 274 disposed on the spray head 273 and the processing frame 11. Limiting rods 42 are symmetrically and fixedly connected to the top of the processing frame 11, and brackets 41 are fixedly connected to the opposing surfaces of the limiting rods 42. Limiting blocks 4 are slidably connected to the brackets 41, and the limiting blocks 4 are fixedly connected to the outer wall of the connecting plate 272.

[0044] In use, the operator places one end of the aluminum material against the inner left wall of the fixed frame 21, then operates the controller 26 to start the motor 25. After starting, the motor 25 drives the lead screw 22 to rotate, causing the movable block 23 threaded onto the lead screw 22 to move outwards. The fixed block 24 connected to the movable block 23 gradually comes into contact with the aluminum material. At this time, the pressure sensor 241 senses the pressure and generates a corresponding electrical signal. When the pressure value exceeds a preset threshold, the controller 26 sends a control signal to stop the motor 25. In this way, the fixed block 24 and the inner wall of the fixed frame 21 stably clamp the aluminum material while preventing excessive pressure from deforming it. The width data of the aluminum material is input into the controller 26. The controller 26 controls the electric push rod 271 and the feeding mechanism 274 to start together. The electric push rod 271 drives the connecting plate 272 to move to the right to the corresponding distance according to the width data of the aluminum material. When the connecting plate 272 moves, the bottom nozzle 273 sprays powder and gradually moves to the right, realizing the spraying of one side of the aluminum material. Then, the controller 26 controls the second motor 261 to start. The second motor 261 drives the fixed frame 21 to rotate 180 degrees through the rotating shaft 211, so that the other side of the aluminum material is flipped to face upwards, which is convenient for the spraying mechanism 27 to spray again without manual flipping, thereby improving the processing efficiency. When the electric push rod 271 drives the connecting plate 272 to move, the limiting block 4 on the outside of the connecting plate 272 slides on the limiting rod 42. The limiting block 4 and the limiting rod 42 provide a clear movement trajectory, so that the connecting plate 272 can move accurately in the predetermined direction, avoiding deviation or shaking, and improving the movement accuracy of the connecting plate 272 and the nozzle 273.

[0045] The aforementioned material conveying mechanism 274 includes a powder hopper, a powder pump, and a powder conveying pipe. The powder hopper stores the powder coating, and the powder pump extracts the powder from the hopper and conveys it to the nozzle 273 through the powder conveying pipe. Simultaneously, a high-voltage generator is installed at the bottom of the connecting plate 272, located near the nozzle 273. This generator provides a high voltage to the nozzle 273 to generate a sufficiently strong electrostatic field, ensuring that the powder particles acquire sufficient charge and that the powder coating is uniformly adsorbed onto the aluminum surface. As long as powder conveying is achieved, spraying is possible; the specific structure will not be elaborated upon here.

[0046] Example 2

[0047] An auxiliary function has been added based on Embodiment 1.

[0048] See Figure 1-4 Two sets of the limiting blocks 4, the brackets 41, and the limiting rods 42 are symmetrically arranged on both sides of the connecting plate 272. Rubber pads 3 are provided on the facing surfaces of the fixing blocks 24 and the fixing frame 21. Slider blocks 5 are fixedly connected to the facing surfaces of the movable blocks 23. Sliding grooves 51 are symmetrically formed inside the fixing frame 21, and the sliders 5 are slidably connected within the sliding grooves 51.

[0049] The limiting blocks 4 on both sides and the limiting rod 42 form a double support structure, which can better balance the force on the connecting plate 272 during movement. When the connecting plate 272 is disturbed by external forces or the load distribution is uneven, the limiting blocks 4 on both sides can play a supporting and adjusting role respectively, effectively preventing the connecting plate 272 from tilting or twisting, and further improving the stability and accuracy of the movement of the connecting plate 272. When the fixed block 24 moves and fixes the aluminum material, the rubber pad 3 on the fixed block 24 and the fixed frame 21 contacts the surface of the aluminum material. The rubber pad 3 increases the friction between the fixed block 24, the fixed frame 21 and the aluminum material, thereby enhancing the fixing effect between the fixed frame 21 and the fixed block 24. When the movable block 23 moves under the influence of the lead screw 22, the movable block 23 drives the slider 5 to slide in the slide groove 51. The slider 5 and the slide groove 51 guide the movement of the movable block 23, increasing the stability of the movement of the movable block 23 while preventing the movable block 23 from detaching from the cavity 221 as a whole, thereby avoiding affecting the fixing effect of the fixed block 24.
