Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a cutting machine, and more particularly to a cutting machine for easily and quickly cutting paper sheets or gold foils or the like into smaller cut chips, and for automatically collecting the cut chips.

2. Description of the Prior Art

Typical cutting machines comprise a base having a fixed cutter edge or blade formed or provided therein, and a movable cutter blade pivotally attached or coupled to the base, and rotatable relative to the base, and movable toward and away from the fixed cutter edge or blade for cutting or trimming paper sheets.

Normally, the typical cutting machines may be used to cut or trim paper sheets into longitudinal paper straps or strips only, but may not easily cut or trim paper sheets into square, or rectangular, or triangular or hexagonal paper cut chips.

For allowing the paper sheets to be cut or trimmed into square, or rectangular, or triangular or hexagonal paper cut chips, the longitudinal paper straps or strips should further be cut or trimmed by the typical cutting machines again, to cut the longitudinal paper straps or strips in a direction perpendicular to the longitudinal paper, in order to form the smaller square, or rectangular, or triangular or hexagonal paper cut chips.

However, it is time consuming and it takes a lot of labor work and it will be difficult to cut paper sheets into the smaller square, or rectangular, or triangular or hexagonal paper cut chips.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional cutting machines.
