The cleaning roller adheres to the stainless steel plate and is driven to rotate by the plate to perform the cleaning work. Furthermore, when the cleaning roller needs to be replaced, it can be automatically replaced via a push mechanism in conjunction with the control mechanism, bracket, and loading box, greatly improving replacement efficiency. The control mechanism controls the main shaft to rotate the cleaning roller to the bracket. During this process, the push rod on the support arm is gradually pushed under the control of the guide plate and limit plate, pushing the insert out of the mounting slot, thereby releasing the connection and fixation between the support arm and the insert arm, enabling rapid separation. As the cleaning roller rotates and passes through the arc-shaped arm on the bracket, it is initially supported and restricted by the arc-shaped arm after reaching the bracket. Then, as the main shaft continues to rotate, the cleaning roller slides along the arc-shaped arm. Simultaneously, as it descends, the insert arm of the cleaning roller continuously disengages from the support arm, achieving automatic disassembly. Attached Figure Description

[0058] A method for using a device for eliminating pickling pattern defects on the surface of hot-rolled stainless steel, specifically as follows:

[0059] 1) Oxidized slag removal: First, the stainless steel plate 6 is turned at the descaling mechanism 1 so that both sides can be cleaned by the cleaning roller 13 on the descaling mechanism 1. During the cleaning process, the first motor 123 drives the main shaft 121 to rotate, thereby driving the branch arm 122, the insertion arm 131 and the cleaning roller 13 to rotate, so that the cleaning roller 13 stops and contacts the surface layer of the stainless steel plate 6 for cleaning;

[0060] 2) Cleaning roller replacement: When the cleaning roller 13 is attached with more oxidized slag, the main shaft 121 rotates to replace the cleaning roller 13. The main shaft 121 drives the cleaning roller 13 to rotate, thereby driving the cleaning roller 13 to the bracket 14. In this process, the push rod 125 on the branch arm 122 is gradually pushed under the control of the guide plate 1241 and the limiting plate 124, pushing the insertion block 1312 out of the installation slot 1223, thereby releasing the connection and fixation between the branch arm 122 and the insertion arm 131, so that they have the condition of separation. When passing through the arc-shaped arm 142 on the bracket 14, the cleaning roller 13 slides along the arc-shaped arm 142 to make the insertion arm 131 separate from the branch arm 122, thereby completing the disassembly of the cleaning roller 13. Then, continue to rotate the main shaft 121 to align the branch arm 122 with the first fixed arm 16 to prepare for the insertion of the insertion arm 131 into the branch arm 122.

[0061] 3) cleaning roller installation: the cleaning roller 13 in the box 15 is lowered by gravity and supported by the first fixed arm 16, the insertion arm 131 is kept horizontal by the cooperation of the third limiting plate 1521 and the flat mouth 1315, then the limiting groove 1311 is accurately fitted with the sliding arm 161, thereby ensuring that the insertion arm 131 and the supporting arm 122 can be smoothly inserted and connected; when the insertion arm 131 is inserted into the supporting arm 122, the end of the insertion arm 131 is inserted into the insertion slot 1222; then the push block 172 is pushed by the push mechanism 17, the push plate 175 on the push block 172 pushes the cleaning roller 13 to move along the sliding arm 161 and insert the supporting arm 122, when the push block is reset, the push plate 175 rotates and presses the arc-shaped arm 176 into the arc-shaped slot 1721 under the block of the cleaning roller 13, after passing the cleaning roller 13, the arc-shaped arm 176 pushes the push plate 175 back to reset under the push of the second spring 177, and the pushing of the cleaning roller 13 is realized by reciprocating;

[0062] At this time, the insertion block 1312 is pushed back into the empty slot 1313 through the inclined slot 1221, then the first spring 1314 is pushed out again at the installation slot 1223 to push out the push rod 125 synchronously, so that the insertion arm 131 and the supporting arm 122 are fixed and connected;

[0063] 4) stainless steel plate pickling: the stainless steel plate 6 is transported into the pickling bin 205 and pickled by acid solution;

[0064] 5) squeezing mechanism squeezing treatment: after the stainless steel plate 6 is pickled, it is squeezed and cleaned by the squeezing roller 32 of the squeezing mechanism 3;

[0065] 6) stainless steel plate washing: the water tank 42 in the washing mechanism 4 supplies water to the water pipe 432 and the spray head 431 on the fixed seat 43, and washes the stainless steel surface to remove the residual liquid after pickling; during the washing process, the third motor 41 can drive the lead screw 441 in the adjusting assembly 44 to rotate to move the fixed seat 43 and the spray head 431, so as to realize the relative concentration and dispersion of the spray head 431 according to the width of the stainless steel plate 6, which is beneficial to improve the washing effect;

[0066] 7) the surface of the stainless steel plate is scrubbed: after the rinsing is completed, the surface of the stainless steel plate 6 is scrubbed by using the scrubbing mechanism 5, not only can the rinsing water be removed, but also the dirt adhered to the surface which cannot be rinsed away can be scrubbed away by the felt cloth 531; in the scrubbing process, the fourth motor 51 drives the chain 52 to rotate, and then drives the chain plate 53 and the felt cloth 531 to rotate and scrub on both sides of the stainless steel plate 6; further, the felt cloth 531 is squeezed by the squeezing mechanism 54 to remove the water in the felt cloth 531, so that the felt cloth 531 is kept dry to a certain extent, which is beneficial to improve the scrubbing effect; the third spring 544 pushes the first compression roller 543 to cooperate with the second compression roller 545 to squeeze the felt cloth 531 on the chain plate 53; after the above treatment is completed, the stainless steel plate 6 is transmitted out of the cabinet 2.
