Description

TECHNICAL FIELD

[0001] The utility model belongs to cutting machine technical field, and specifically is a packaging box processing cutting machine. BACKGROUND

[0002] In the field of modern logistics and commodity packaging, packaging boxes, as indispensable packaging materials, have a growing demand with the rapid development of the e-commerce industry and the packaging box demand of product diversification. These packaging boxes need to be cut and processed into appropriate sizes by cutting machines to meet the precise needs of product packaging.

[0003] In the prior art, the paperboard is placed above the lower cutting knife, and then the upper cutting knife is driven downward by the hydraulic rod to cut the paperboard. However, during the cutting process, the paperboard is usually pressed and clamped by the telescopic device for positioning. However, when the telescopic device contacts the paperboard, if the pressing force is too large, it is easy to cause indentation on the contact part of the paperboard, which affects the quality of the paperboard. If the pressing force is too small, the paperboard cannot be effectively pressed, which affects the processing. Therefore, we propose a packaging box processing cutting machine.
