Description

Technical Field

[0001] This utility model relates to the field of cardboard cutting technology, and in particular to a cardboard cutting device that facilitates automatic paper replacement. Background Technology

[0002] Cardboard is widely used in packaging, logistics, printing, and decoration industries. To meet the size requirements of various industries, the produced cardboard needs secondary processing, cutting large pieces into the required dimensions. During cardboard cutting, because the same cardboard product often requires assembly using cardboard of different sizes, the original cardboard on the feeding mechanism needs to be replaced during the cutting process to produce different cardboard modules. This ensures that all the necessary components for the cardboard product are cut and produced. Therefore, the cardboard on the cutting machine needs to be changed frequently.

[0003] Existing cardboard cutting equipment requires changing different cardboards for cutting, and the frequent feeding and pushing of different cardboards is time-consuming. It fails to pre-place multiple different cardboards to be cut to reduce the time wasted on feeding. Moreover, before the cardboard is cut, the parts far from the cutting point are prone to lifting, and it is not possible to flatten them to ensure accurate cutting.

[0004] Therefore, we provide a paperboard cutting device that facilitates automatic paper replacement. Utility Model Content
