6. The device for initially processing and flattening the advertising board as claimed in claim 1, wherein the bottom surfaces of the left limiting block (109) and the right limiting block (110) are abutted against the table top of the workbench (1).

7. The primary processing and flattening device for the advertising board as claimed in claim 1, wherein a first guide post (108) is horizontally arranged on two sides of a screw rod (106) in side plates (105) on two sides of the bottom surface of the workbench (1), through holes matched with the first guide post (108) are respectively formed in the first nut seat (111) and the second nut seat (112), and the first nut seat (111) and the second nut seat (112) are slidably connected to the first guide post (108) through the through holes.

8. The primary processing and flattening device for the advertising board as claimed in claim 1, wherein a plurality of supporting legs are arranged on the bottom surface of the workbench (1), an object placing plate (101) is horizontally arranged between the supporting legs, and a cup mat (102) and a guide wheel (103) are fixedly arranged on the ground of the supporting legs.

9. A use method for a billboard primary processing leveling device is characterized by comprising the following specific steps:

the method comprises the following steps: the first screw (106) is driven to rotate by the first motor (107), so that the first screw (106) drives the first nut seat (111) and the second nut seat (112) on the two sides to move on the first screw (106) in the opposite direction or the reverse direction, the first nut seat (111) and the second nut seat (112) drive the first support column (113) and the second support column (114) to adjust the distance between the left limiting block (109) and the right limiting block (110), a support plate (115) is erected in L-shaped notches of the left limiting block (109) and the right limiting block (110), and the billboard to be leveled is covered on a plane formed by the left limiting block (109), the right limiting block (110) and the support plate (115);

step two: the piston rod is driven by the cylinder (204) to push the connecting plate (207) to move, so that the connecting plate (207) drives the clamping plate (209) to move, and the clamping plate (209) is abutted against the side face of the billboard, thereby completing the clamping and fixing of the clamping plate (209) on the right fixed rack (2), the left fixed rack (3) and the front fixed rack (4) on three faces of the billboard;

step three: through rotating runner (503), make runner (503) drive screw rod two (502) rotate, make screw rod two (502) drive riser (506) move in vertical direction to make riser (506) drive diaphragm (508) and move in vertical direction, adjust levelling plate (511) height in vertical direction, and drive piston rod through pneumatic cylinder (507) and promote locating plate (509) and move down, thereby make locating plate (509) drive levelling plate (511) level the surface of bill-board.
