Then, only the first hand wheel 7 is rotated, the first hand wheel 7 drives the first lead screw 19 to rotate, the first lead screw 19 drives the moving block 14 on the third roller part 12 to move in a direction away from the second roller part 11, a gap is formed between the third roller part 12 and the second roller part 11, after the third roller part 12 is moved, the first bolt 21 is inserted between the first hand wheel 7 and the rotating shaft 16, and the second bolt 22 is inserted between the second hand wheel 8 and the first hand wheel 7, so that the first lead screw 19 and the second lead screw 20 are fixed. Because a gap is formed between the second roller part 11 and the third roller part 12, paint on the second roller part 11 cannot diffuse to the third roller part 12, and paint cannot be supplemented to the third roller part 12, so that the phenomenon that the paint is continuously adsorbed on the third roller part 12 in a suspended state to cause more paint to drip on the outer side of the plate is avoided, and the waste of the paint is avoided.

Then, the first hand wheel 7 is rotated, the first hand wheel 7 drives the first lead screw 19 to rotate, the first lead screw 19 drives the moving block 14 on the third roller part 12 to move in a direction away from the second roller part 11, and a gap is formed between the third roller part 12 and the second roller part 11. Then, the second hand wheel 8 is rotated, the second hand wheel 8 drives the second lead screw 20 to rotate, the second lead screw 20 drives the moving block 14 on the second roller part 11 to move, the second roller part 11 moves in a direction away from the first roller part 10, and thus a gap is formed between the second roller part 11 and the first roller part 10. Then, the first bolt 21 is inserted between the first hand wheel 7 and the rotation shaft 16, and the second bolt 22 is inserted between the first hand wheel 7 and the second hand wheel 8 to fix the first lead screw 19 and the second lead screw 20. Because the gap is formed between the second roller part 11 and the first roller part 10, paint on the first roller part 10 cannot spread to the second roller part 11, paint cannot be supplemented to the second roller part 11 and the third roller part 12, the phenomenon that the paint is continuously adsorbed on the second roller part 11 and the third roller part 12 in a suspended state and more paint is dropped on the outer side of the plate under the action of weight is avoided, and waste of the paint is avoided. And the first roller portion 10 is now against the sheet material so that paint is applied to the sheet material.
