The pickling box and the floating rollers 3 used for support are of a line contact structure, which ensures that the pickling box is wrapped with concentrated sulfuric acid as much as possible, so that the electrode plates inside are fully immersed, thereby improving the pickling effect.

[0035] The traction assembly includes two groups of traction ropes 9. A first ear plate 6 and a second ear plate 7 are fixedly installed above the bracket 4 and above the pickling tank 1 respectively.

[0037] The pickling device also includes a traction assembly for driving the roller frame to rise and fall, and the traction assembly also includes a first motor 11 fixedly installed on the outer wall of the pickling tank 1. The output end of the first motor 11 is transmission-connected with a traction shaft 10, and the traction shaft 10 is rotatably installed on the outer wall of the pickling tank 1. Pulleys 8 are also fixedly installed at both ends of the traction shaft 10. Cylinders 12 are symmetrically installed on the outer wall of the pickling tank 1 on both sides of the first motor 11.

[0038] In this embodiment, the steps of controlling the pickling tank are as follows:

[0039] The first motor 11 is started, and the first motor 11 drives the traction shaft 10 to rotate, and the pulleys 8 at both ends of the traction shaft 10 rotate, and the traction rope 9 is loosened. One end of the traction rope 9 is connected to the pulley 8 on the first ear plate 6. Therefore, when the pickling box is placed on the floating roller 3, the floating roller 3 supports the pickling box to sink under the action of gravity, so that the battery production plate is completely immersed in the pickling tank 1.

[0053] A fixing frame 21 is fixedly installed on one side of the cleaning pool 2, and a second guide bar 22 is provided on one side of the fixing frame 21 and the inner wall of the cleaning pool 2. A rack 24 is slidably installed in the second guide bar 22, and one end of two sets of racks 24 are connected with a screw 28, and two sets of screws 28 are threadedly connected in the internal threaded sleeve 27. The surface of the internal threaded sleeve 27 is connected with a second gear 26.

[0054] In this embodiment, the main pipe 17 is driven to rotate a certain angle, preferably ±55°, by the rotating drive assembly. Specifically, the second motor 29 is started, and the second motor 29 drives the first synchronous pulley 31 at its output shaft end to rotate, and transmits to the first synchronous pulley 31 at the shaft end of the driving rod 30, thereby driving the driving rod 30 to rotate. A second gear 26 is provided at one end of the driving rod 30, and a second gear 26 is also fixedly installed on the surface of the internal threaded sleeve 27. The two sets of second gears 26 are meshed, thereby driving the internal threaded sleeve 27 to rotate on one side of the inner wall of the cleaning tank 2. The two sets of screws 28 are respectively provided with left-handed external threads and right-handed external threads, and the inner wall of the internal threaded sleeve 27 is respectively provided with left-handed internal threads and right-handed internal threads matching the left-handed external threads and the right-handed external threads. Therefore, by using the forward and reverse rotation of the second motor 29, the two sets of first racks 24 can be made close to or away from each other through the rotation of the internal threaded sleeve 27, thereby driving the first gear 23 to rotate forward and reverse, and finally realizing the forward and reverse rotation of the upper and lower main pipes 17 within a certain angle range.

Therefore, when the pickling box is placed on the floating roller 3, under the action of gravity, the floating roller 3 supports the pickling box to sink, so that the battery production plate is completely immersed in the pickling tank 1.

[0056] After the pickling treatment, the first motor 11 is started to drive in reverse, and the pulleys 8 at both ends of the traction shaft 10 rotate to reel in the traction rope 9, thereby pulling the first ear plate 6 to pull the brackets 4 on both sides and the floating rollers 3 between the two groups of brackets 4 and the pickling box to the outside of the concentrated sulfuric acid, and the cylinder 12 is started to push the pickling box to the top of the cleaning tank 2;

During the rotation process, the cleaning rollers 13 use the convex ribs 32 to contact and move the pickling box to continuously transport it to the subsequent battery production process. At the same time, the convex ribs 32 lift the pickling box to a certain height, so that the gap between the cleaning rollers 13 and the pickling box is used to make the water outlet 39 flow smoothly, and the pickling box is cleaned as fully as possible.

[0058] The second motor 29 is started to rotate forward and reverse, and the two sets of first racks 24 are moved closer or farther away from each other by rotating the internal thread sleeve 27, thereby driving the first gear 23 to rotate forward and reverse, and finally realizing the forward and reverse rotation of the upper and lower sets of main pipes 17 within a certain angle range.

[0060] The second motor 29 drives the first synchronous pulley 31 at its output shaft end to rotate, and transmits it to the first synchronous pulley 31 at the shaft end of the driving rod 30, thereby driving the driving rod 30 to rotate, and the driving rod 30 drives the internal threaded sleeve 27 to rotate on one side of the inner wall of the cleaning tank 2, and the two groups of screws 28 are respectively set to left-handed external threads and right-handed external threads, and the inner wall of the internal threaded sleeve 27 is respectively provided with left-handed internal threads and right-handed internal threads that match the left-handed external threads and the right-handed external threads. Therefore, by utilizing the forward and reverse rotation of the second motor 29, the two groups of first racks 24 can be moved closer to or away from each other through the rotation of the internal threaded sleeve 27, thereby driving the first gear 23 to rotate forward and reverse, and finally realizing the forward and reverse rotation of the upper and lower groups of main pipes 17 within a certain angle range, ensuring the spray cleaning range as large as possible.
