Improved power paper cutter

Abstract

The invention discloses an improved power paper cutter. The improved power paper cutter comprises a base, a blade, a lower die, a support and a power device, wherein the blade is arranged on the basethrough the support, a sliding pair is arranged between the blade and the support, the power device is fixedly connected with the base or the support, the power output end of the power device is connected with the blade through a transmission mechanism, the lower die is arranged in the upper plane of the base, and the cutting edge of the blade is positioned above the lower die and is parallel to the lower die. The improved power paper cutter is characterized in that an included angle between the upper plane of the base and the horizontal plane is 15-80 degrees, the length direction of the lower die is parallel to the upper plane of the base, the length direction of the cutting edge of the blade is parallel to the upper plane of the base, a linear limiting convex strip is arranged at the lower edge of the upper plane of the base, and the length direction of the limiting convex strip is parallel to the horizontal plane and perpendicular to the length direction of the lower die. The paperis automatically perpendicular to the limiting convex strip under the action of gravity and is parallel to the upper plane of the base, and tidy paper cutting can be achieved when more pages of the stacked paper are cut.

Description

technical field [0001] The present invention relates to the field of machinery, in particular to a paper cutting device, in particular to a power-driven improved power paper cutter, in particular to an improved power paper cutter. Background technique [0002] Improved power cutters, either electrically or hydraulically driven, are widely used to trim the sheets during the binding process. In the prior art, an improved power paper cutter driven by electric or hydraulic pressure includes a base, a blade and a power device, the blade is arranged on the base through a bracket, and the power device drives the blade to move relative to the base through a transmission mechanism. The base is basically parallel to the horizontal plane, the cutting edge of the blade is parallel to the base, and the movement plane of the cutting edge of the blade is perpendicular to the base. During the paper cutting process, in order to keep the paper tidy, it is necessary to set limit protrusions o...

AI Technical Summary

Problems solved by technology

During the paper cutting process, in order to keep the paper tidy, it is necessary to set limit protrusions on the edge of the base. However, when cutting paper with a large number of stacked pages, the blade will push the paper that has been cut, and the paper that has been cut will be separated from the paper below. The friction force between the uncut paper on the side will take the uncut paper on the lower side away from the predetermined limit, making the paper cut uneven
