Description

Paperboard cutting device Technical Field The utility model relates to the technical field of cardboard cutting, and more particularly relates to a cardboard cutting device. Background In the field of cardboard packaging manufacture, cutting devices are one of the core devices, the performance of which directly affects the production efficiency and the product quality. Conventional paperboard cutting devices typically employ a single cutting disc structure that cuts paperboard straight through a high-speed rotating disc knife. Such devices perform well in the face of conventional paperboard having a thickness of less than 3mm, but as the demand for large-size packaging boxes, heavy-duty logistics boxes and the like grows, the paperboard thickness gradually increases to 5-10mm, and the limitations of conventional single-disc cutting schemes are increasingly pronounced. In the prior art, the core problem of the single cutting disc structure is that the complete cutting of the thick paper board cannot be completed at one time. For example, when the cardboard thickness exceeds 3mm, the peripheral cutting edge of a single cutting disc is difficult to penetrate the full thickness of the material, resulting in incomplete cutting and secondary processing. This not only increases the equipment run time, but also results in uneven cuts due to repeated positioning errors, affecting the yield of finished products. To solve the above problems, some improvements have attempted to enhance the penetration force by increasing the diameter of the cutting disc or increasing the rotational speed, but have had limited effectiveness. For example, increasing the disk diameter can prolong the cutting contact time, but leads to a significant increase in equipment volume and energy consumption, while increasing the rotational speed can increase tool wear and shorten the service life. Based on this, a new paperboard cutting apparatus is needed.
