8. The device for producing formaldehyde-free maternity board according to claim 2, characterized in that: The marking mechanism (4) comprises an ink storage box (401), a delivery pump (402) and a bellows (403); the ink storage box (401) is fixed on the top of the processing frame (2); one end of the ink storage box (401) is connected to the delivery pump (402); the output end of the delivery pump (402) is connected to the bellows (403); the bottom end of the bellows (403) is connected to the inkjet head (404); and a limiting rod (405) is fixed inside the processing frame (2).

9. The device for producing formaldehyde-free maternity board according to claim 8, characterized in that: The inner wall of the inkjet head (404) is close to the inner wall of the limiting rod (405), and the inkjet head (404) and the limiting rod (405) are slidably connected.

10. A method for producing a non-aldehyde-added maternity board, using the non-aldehyde-added maternity board production device according to claims 2-9, characterized in that: The following steps are involved: S1, placing the maternity board on the top of the base (1) for transportation, so that it moves on the top of the base (1), the maternity board first passes the bottom of the limiting frame (502), and when it is located in the middle of the limiting frame (502), the transportation of the maternity board is stopped, and the third servo motor (501) is started to drive the second screw (503) to rotate, thereby driving the position of the connecting block (504) to move, thereby driving the embossing cylinder (505) to move and rotate, so that the embossing cylinder (505) presses the surface of the maternity board through the embossing block installed in the installation groove (506) when moving, so that the surface of the maternity board has a shortened distance pattern (12), thereby shortening the contact distance between the air and the activated carbon layer (13), and expanding the contact space between the activated carbon layer (13) and the air, and improving the efficiency of the maternity board in absorbing harmful substances by expanding the contact area between the activated carbon layer (13) and the air, thereby protecting the safety of users using the maternity board; S2. After being pressed, the maternity board is continuously conveyed so that the maternity board with the top pressed is located at the bottom of the polishing sleeve (310), the first servo motor (301) is started to drive the first bevel gear (302) to rotate, the first bevel gear (302) drives the connecting rod (303) and the third bevel gear (305) to rotate, so that the third bevel gear (305) drives the first screw (307) to rotate, and then the lifting block (308) is driven to move up and down by the shape of the first screw (307), thereby changing the position of the polishing sleeve (310), so that when the second servo motor (311) is started to drive the polishing sleeve (310) to rotate to polish the maternity board, it can better contact with the maternity board for operation, thereby compensating for the loss of the polishing sleeve (310) after long-term use; S3. During polishing, sawdust is generated, and the dust collecting fan (8) is started. The dust collecting fan (8) generates wind force when rotating, and collects the sawdust into the dust collecting box (9) through the dust collecting groove (7); S4. When the processing area of ​​the maternity board moves to the bottom of the inkjet head (404), the inkjet position of the inkjet head (404) is adjusted according to the width of the maternity board, so that the ink is located at the distance from the inside to the outside of the turning cylinder (602) of the maternity board, and is marked, so that the device can judge the height of the movable plate (606) according to the position of the ink, thereby ensuring the effect of subsequent turning; S5, the maternity board is moved to the inside of the turning groove (603) provided in the turning cylinder (602), and the fourth servo motor (601) is started to drive the fourth servo motor (601) to drive the limiting frame (502) and the maternity board to turn over, so as to perform a polishing and pressing operation on the back of the maternity board. Furthermore, the third screw rod (605) is rotated to drive the movable plate (606) to move inside the connecting frame (604), so as to change the space occupied by the turning groove (603), so that the device can turn over maternity boards of different widths through adjustment.
