[0002] Composite cardboard is mainly made from waste newspapers and recycled packaging paper products. After being made into board paper, it is compounded into cardboard with relatively high thickness. This kind of cardboard is the most environmentally friendly. Composite cardboard can be widely used in cartons and cartons. Composite paper is usually produced continuously during production, and the produced composite cardboard is relatively long, so cutting equipment is needed to cut the composite cardboard.

[0003] In order to ensure the safety of the operator when operating the cutting device to cut paper when the existing cutting device cuts the composite cardboard, the patent publication number CN219543415U discloses a safe composite cardboard cutting table, which uses an infrared imager and an optical camera to monitor the personnel and debris near the cutting blade. When the cutting table is not started, it is detected that there are people near the cutting blade or there are debris on the workbench, the cardboard cannot be placed flat, and the cutting table cannot be started; when the cutting table is in operation, it is detected that there are people or debris. The motor brake can be controlled to avoid or reduce damage to personnel, which can effectively improve the safety of automatic cutting operations. Although the safety of the operator is improved, the above scheme cuts the composite cardboard by rotating the saw blade with serrated teeth. When the saw teeth rotate and cut, it is easy to cause burrs at the cutting position of the composite cardboard, which is easy to affect the quality and effect of the cardboard cutting, and then it is easy to affect the subsequent use of the composite cardboard.
