Die-cutting pressure, paper feeding speed, and positioning accuracy are the core process parameters in the operation of a fully automatic high-speed die-cutting machine. These three parameters are interrelated and each determines the overall operating condition of the equipment from three aspects: product quality, production efficiency, and equipment stability. Their specific impacts are as follows: 

   Die-cutting pressure is the core parameter that ensures the quality of die-cutting results. It directly determines the edge quality and the clarity of the indentations of materials such as paper and corrugated cardboard. If the die-cutting pressure is too low, problems such as incomplete knife marks, inability of the paper to be completely separated, shallow indentations and easy rebound will occur, resulting in the inability of the finished product to be folded properly or difficulties in clearing waste. At the same time, the uncut paper may also wrap around the transmission components during the high-speed operation of the equipment, causing jamming or even blade and die breakage. If the pressure is too high, it will not only accelerate the wear rate of the die-cutting die and shorten its service life, but also cause the paper board to collapse, severe edge burrs on the paper, and for corrugated cardboard, excessive pressure will collapse the corrugation pattern, affecting the load-bearing performance of the packaging finished product. In addition, exceeding the rated pressure will increase the load on the hydraulic or mechanical transmission system of the equipment, causing overload of the motor, deformation of the press plate, and other equipment damages, and reducing the stability of the entire machine operation. 

   The paper feeding speed is a key indicator that affects production efficiency and the smooth operation of the equipment. It needs to be matched with the die-cutting pressure and the mechanical structure performance of the equipment. Increasing the paper feeding speed within a reasonable range can directly enhance the production capacity per unit time, meeting the efficiency requirements of large-scale production. However, when the paper feeding speed is too fast, the materials are prone to skewing and sliding during transportation, resulting in deviation of the die-cutting position. At the same time, high-speed transportation will increase the friction loss between the paper feeding rollers and the paper, causing static electricity to attract paper debris, thereby affecting the subsequent die-cutting and waste removal processes. If the paper feeding speed is too slow, although it can improve the stability of single paper feeding, it will reduce the overall production efficiency. Moreover, in a low-speed operation state, the motor and transmission system of the equipment are prone to low-frequency vibration. Long-term low-load operation will cause energy waste and ineffective loss of components. At the same time, due to the slow production rhythm, it will affect the connection between the previous and subsequent processes, reducing the overall coordination of the production line.
