When the number of times of replacement (500) of the back and forth movement of the scouring pad 200 is reached, the lifting mechanism lifts the translation mechanism, the 180-degree rotary cylinder 9 rotates 180 degrees, so that the scouring pad holder 5, the force sensor 6, the vertical guide rod 7 and the scouring pad 200 of the preparation group are downward, the previous scouring pad holder 5, the force sensor 6, the vertical guide rod 7 and the scouring pad 200 are upward, the opening of the previous scouring pad holder 5 is upward opened, the scouring pad 200 cannot fall randomly, the scouring pad 200 is replaced, and after the scouring pad holder 5 is closed, the controller 1 controls the translation cylinder 10 to work when the change value of the data signal of the force sensor 6 of the preparation group reaches a set value in the process of descending the translation mechanism by the lifting mechanism.
