Bulk paper board cutting tool

Abstract

The invention discloses a bulk paper board cutting tool which comprises a plurality of circle ring-shaped first blades (3) which are arranged on an upper cutter shaft (1) and a plurality of circle ring-shaped second blades (4) which are arranged on an lower cutter shaft (2), a plurality of first blades (3) and the plurality of circle ring-shaped second blades (4) are distributed in an interlaced way and embedded in each other, on the circumference surface of each of the first blades (3) and on each of the second blades (4) are provided with at least a pair of gap I (6) and gap II (7), the distance from a middle point of a circular arc to which the gap I (6) corresponds to the axial line of the lower cutter shaft is equal to the distance from a middle point of a circular arc to which the gap II (7) corresponds to the axial line of the upper cutter shaft, and the middle point of the circular arc the gap I (6) corresponds to and the middle point of the circular arc the gap II (7) corresponds to are on the line of the circle centre of the two blades, or at the same side of the line of the circle centre of the two blades. The cutting tool of the invention can cut the bulk paper board into a reticulation and the paper board after being cut has good damping effect, convenient usage and can save usage amount of the paper board.

Description

technical field [0001] The invention relates to a cutting tool for a paper shredding device, in particular to a cutting tool for bulky cardboard. Background technique [0002] Packaging filling materials mainly include plastic foam, wood chips and cardboard. Plastic foam filling materials will pollute the environment because they are not easy to degrade; wood chips have a great demand for wood, so long-term use will greatly damage the natural environment. Therefore, some countries that pay attention to environmental protection in the world have clearly required the use of cardboard Similar filling materials to replace the filling materials of plastic foam and wood chips. [0003] Since it is inconvenient to fold the entire cardboard into various shapes for filling, it will be cut with a shredder and then filled. At present, it is generally cut into the following two shapes: [0004] 1. Cut the cardboard into strips. If this kind of strip cardboard is stacked up as a filli...
