Example Embodiment

[0020] Description with accompanying drawings.

[0021] The frame of the paper cutting device of the illustrated embodiment includes left and right vertical wall panels 11 and a bottom surface. The wall panels 11 on both sides are parallel to each other. The upper knife linear guide 8 is installed between them, and the upper knife linear guide 8 is perpendicular to the wall panel 11. , The rubber wheel seat linear guide 7 on the bottom is parallel to the upper knife linear guide 8, see figure 2 .

[0022] figure 2 with 4 As shown, the upper knife rotation driving power drives the upper knife 1 to rotate. The upper knife rotation drive power in this embodiment is the upper knife rotation drive motor 9. The upper knife rotation drive motor 9 mounted on the left wall plate 11 transmits the output power to the upper knife rotation drive active timing belt via the timing belt wheel and timing belt. The wheel shaft, the active timing belt wheel shaft for the upper knife rotation drive...

Abstract

The invention relates to a paper cutter, and in particular relates to a paper cutting device of a paper cutter without a lower cutter. The paper cutting device is used for cutting paper. The paper cutting device is characterized in that an upper cutter is matched with the external diameter of a rubber wheel installed on a rubber wheel seat to cut paper; the upper cutter is vertical to the axis of the rubber wheel; and a paper supporting plate is fixedly installed on the rubber wheel seat. The paper cutting device has the following advantages that the technical problems that the paper cutting devices of the existing paper cutters are easily worn, are short in service life and high in costs, waste time and labour in changing cutters and generate deckle edges and winding when in cutting paper are solved.

Description

technical field [0001] The invention relates to a paper cutter, in particular to a paper cutting device of a paper cutter without a lower knife. Background technique [0002] The paper cutting device of the traditional paper cutter uses metal upper and lower blades to cut the paper. The long-term mutual friction and collision during the knife setting greatly reduce the service life of the upper knife, and the phenomenon of knife collapse occurs from time to time. , and it takes time and effort to change the knife, and the paper is prone to burrs. Chinese Invention Patent Publication No. CN 1954978A "Paper Cutting Device" discloses a paper cutting device in which a wheel-shaped knife seat is made of rubber material, and the lower circular knife suit is fixed on the knife seat. Although this patent reduces the difficulty and time of changing the knife, it does not fundamentally solve the defects that the blade is easy to wear and paper cutting is prone to burrs. Chinese Util...
