[0002] A die-cutting machine is a device used for processing and manufacturing various materials, mainly for operations such as cutting, indentation, punching, and laminating of sheet materials. It has a wide range of applications in industries such as packaging, printing, electronics, automotive, and medical. Currently, common die-cutting machines are used for die-cutting cardboard. When in use, the die-cutting machine transports the cardboard to the inside of the die-cutting machine for processing by a feeding mechanism. However, the existing paper feeding mechanism lacks the function of flattening the cardboard. Since the cardboard as a raw material may be bent and deformed during storage and transportation, it affects the die-cutting effect. In addition, the existing paper feeding mechanism is inconvenient to adjust and cannot position cardboard raw materials of different widths. Therefore, in view of the above current situation, there is an urgent need to develop a die-cutting machine paper feeding mechanism with the function of flattening the cardboard, convenient adjustment, and easy positioning of cardboard of different widths to overcome the deficiencies in current practical applications and meet the current needs.
