Essentially, this is because a layer of oxide film is covered on the metal surface, thus improving the corrosion resistance of the pre-coated sheet. The existing metal sheet passivation reaction machine sprays the passivation liquid onto the front of the aluminum sheet through an upper spray method, and the excess passivation liquid flows into the accumulation tray. The passivation liquid in the tray is picked up by the lower reaction steel roller and brought to the lower reaction rubber roller, and then rolled onto the back of the pre-coated sheet through the lower reaction rubber roller.
[0003] However, in the prior art, when the passivation mechanism is performing passivation operations on the back of small and medium-sized pre-coated plates, it is necessary to wait for the passivation liquid to flow into the accumulation tray and reach a certain liquid level before the lower reaction rubber roller can perform the passivation operation. If the liquid level is too high, the staff is required to discharge the passivation liquid in time before continuing to work, which reduces the processing efficiency of the equipment. In view of the above problems, a self-cleaning pre-coated plate passivation mechanism is proposed. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0021] Embodiment 1

A clamping plate 29 is fixedly installed at one end, and the two clamping plates 29 are respectively slidably connected to the two ends of the mounting frame 25. A limiting roller 221 is fixedly installed at one end of the No. 1 fixed plate 22, and the outer surfaces of the two rollers 28 are both in contact with the inclined ends of the limiting roller 221. The No. 1 fixed plate 22 is arranged between the driving device 21 and the No. 2 fixed plate 23. The bottom end of the No. 1 fixed plate 22 is fixedly installed on the side of the top of the workbench 1 away from the liquid collecting tank 6, and the bottom end of the No. 2 fixed plate 23 is fixedly installed on the side of the top of the workbench 1 close to the liquid collecting tank 6. A spring 8 is movably sleeved on one end of the movable rod 26, and one end of the spring 8 is fixedly connected to the other end of the movable block 27, and the other end of the spring 8 is fixedly connected to one end of the rotating disk 231.
[0023] The specific settings and functions of this embodiment are described in detail below. The driving device 21 is a reduction motor. When the driving device 21 is working, it will drive the rotating rod 24 to rotate. When the rotating rod 24 rotates, the rotating disk 231 will rotate with it. The rotating disk 231 can rotate in the second fixed plate 23. When the rotating disk 231 rotates, the movable rod 26 thereon will slide on the rotating disk 231 due to the limiting effect of the inclined surface of the limiting roller 221. The lower part of the inclined end of the limiting roller 221 is longer. When the movable rod 26 abuts against the lower part of the inclined end of the limiting roller 221 through the roller 28, it will slide toward the direction of the mounting frame 25. The roller 28 can reduce the friction between the movable block 27 and the limiting roller 221 The movable block 27 will squeeze the spring 8, causing the spring 8 to generate elastic force, and at the same time, the clamping plate 29 will gradually stick to the bottom end of the installation frame 25. A pre-coated sheet is placed in the installation frame 25, and the pre-coated sheet will be supported by the clamping plate 29 when it is turned over to prevent the pre-coated sheet from falling from the installation frame 25. At the same time, the movable rod 26 located above the inclined end of the limiting roller 221 will be recovered inwardly due to the elastic force released when the spring 8 recovers its elastic deformation, so that the pre-coated sheet in the installation frame 25 is exposed, which is convenient for the top surface of the pre-coated sheet to be sprayed. When the passivation operation is performed, the pre-coated sheet can be turned over to facilitate the spraying of the passivation liquid on both sides of the pre-coated sheet, and there is no need to wait for the height of the liquid level below to reach a suitable position, thereby improving the processing efficiency.
[0024] Embodiment 2
[0025] like Figure 1 , Figure 3 and Figure 4 As shown, a storage box 3 is movably installed on one side of the workbench 1, and a spray pipe 4 is fixedly connected to the top of the storage box 3.

A liquid collecting tank 6 is opened on the top of the workbench 1, and the liquid collecting tank 6 is arranged below the installation frame 25. A collecting box 7 is arranged inside the workbench 1, and the liquid collecting tank 6 is fixedly connected to the collecting box 7.
[0026] The effect achieved by the entire embodiment is that a water pump is arranged inside the spray pipe 4, and a passivation liquid is arranged inside the storage box 3. The spray pipe 4 sucks the passivation liquid in the storage box 3 out through the internal water pump and sprays it on the pre-coated plate. The support frame 5 can support the spray pipe 4. At the same time, the staff can also remove the spray pipe 4 from the support frame 5 for manual spraying to prevent uneven spraying on the surface of the pre-coated plate during automatic spraying. After the passivation liquid is sprayed out, a part of it will flow into the liquid collecting tank 6. A through groove is provided on one side of the liquid collecting tank 6. The collected passivation liquid will flow from the through groove on the liquid collecting tank 6 into the collecting box 7. A switch door is provided on one side of the workbench 1. After the staff opens the switch door, the collecting box 7 can be taken out from the workbench 1, and the passivation liquid in the collecting box 7 can be recycled, thereby avoiding the waste of processed raw materials and reducing production losses.
[0027] The use method and working principle of this device are as follows: the driving device 21 is a reduction motor. When the driving device 21 is working, it will drive the rotating rod 24 to rotate. When the rotating rod 24 rotates, the rotating disc 231 will rotate with it. The rotating disc 231 can rotate in the second fixed plate 23. When the rotating disc 231 rotates, the movable rod 26 thereon will slide on the rotating disc 231 due to the limiting effect of the inclined surface of the limiting roller 221. The lower part of the inclined end of the limiting roller 221 is longer. When the movable rod 26 abuts against the lower part of the inclined end of the limiting roller 221 through the roller 28, it will slide toward the direction of the installation frame 25. At this time, the movable block 27 will squeeze the spring 8, causing the spring 8 to generate elastic force. At the same time, the clamping plate 29 gradually sticks to the bottom end of the installation frame 25. A pre-coated sheet is placed in the installation frame 25. The pre-coated sheet will be supported by the clamping plate 29 when it is turned over to prevent the pre-coated sheet from falling from the installation frame 25. The spray pipe 4 can suck the passivation liquid in the storage box 3 out and spray it on the pre-coated plate, and the support frame 5 can support the spray pipe 4. At the same time, the staff can also remove the spray pipe 4 from the support frame 5 for manual spraying to prevent uneven spraying on the surface of the pre-coated plate during automatic spraying. After the passivation liquid is sprayed out, a part of it will flow into the liquid collecting tank 6. A through groove is provided on one side of the liquid collecting tank 6. The collected passivation liquid will flow into the collection box 7 from the through groove on the liquid collecting tank 6. A switch door is provided on one side of the workbench 1.
