Description

Technical Field

[0001] The utility model belongs to the technical field of sheet material cutting, and particularly relates to a sheet material cutting device. Background Art

[0002] On the packaging box production line, after the pressed packaging boxes are taken out, the whole piece of waste plastic needs to be cut into smaller pieces for easy stacking, transportation, and recycling. Therefore, the staff will place these whole pieces of waste plastic in the limiting groove on the cutting device, and then use the cylinder to push the blade to cut the rectangular sheets of waste plastic.

[0003] The Chinese patent with the publication number "CN212400032U" discloses a sheet cutting device, including a conveyor, characterized in that a knife holder is provided at the output end of the conveyor, a movable cutter is provided on the knife holder, the movable cutter is connected to a connecting rod, the connecting rod is connected to a lower power cylinder, and a lifting plate is provided on the knife holder above the movable cutter, and the lifting plate is connected to an upper power cylinder. After the sheet moves to the cutting position with the conveyor, the upper power cylinder first drives the pressing plate to press down to fix the sheet, and then the lower power cylinder drives the connecting rod and the movable cutter to move along the knife groove to cut the sheet.
