Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboard cutting, in particular to a corrugated cardboard cutting device. Background Art

[0002] Corrugated cardboard is a multi-layer structural material consisting of a flat cardboard and an intermediate layer (corrugated paper). This material consists of a series of longitudinal peaks and troughs, with a thin layer of honeycomb cardboard between the peaks and troughs. This structure gives the corrugated cardboard excellent compression resistance and cushioning properties. Corrugated cardboard is widely used in packaging, transportation and protection of items due to its light weight, strength and environmental protection. In the production and processing of corrugated cardboard, a cutting device is used to cut the corrugated cardboard into specific sizes and shapes. This cutting process can customize the corrugated cardboard to meet the needs of various packaging, boxes and other uses.

[0003] A Chinese patent document with a search announcement number of CN216993217U discloses a corrugated cardboard cutting device, comprising a cutting table with a cutting groove on the upper surface, a mounting plate fixedly mounted on the cutting table via a plurality of columns, two sliding rods mounted on the mounting plate via a sliding structure, a movable plate fixedly mounted on the upper ends of the two sliding rods, a movable structure installed between the mounting plate and the movable plate, and a plate body 1 fixedly mounted on the lower ends of the two sliding rods. The advantages are: with the cooperation of the gear and the gear rod, the blade can be automatically rotated while moving, so that the rotation and cutting of the blade does not require an additional power source, saving the use cost; at the same time, through the cooperation of the blocking cover and the collecting seat, the debris generated in the cutting process is effectively blocked and collected, and with the cooperation of the plate body 2, the clamping rod and the clamping slot, it is convenient to regularly process the collected debris. During the cutting process of the corrugated cardboard, the corrugated cardboard cutting device requires the staff to fix the corrugated cardboard by hand. Manually fixing the corrugated cardboard may require the staff to maintain a relatively fixed posture for a long time, which will result in high labor intensity. Long-term repeated operations will lead to poor fixing effect, resulting in the corrugated cardboard being offset during the cutting process, which reduces the stability of the corrugated cardboard cutting.
